Technical Field

The invention relates to the technical field of medical instruments, in particular to an examination bed.

Background

Magnetic Resonance Imaging (MRI) is a widely used auxiliary examination modality in modern medicine. During the nuclear magnetic resonance examination, a subject is generally placed on a bed board of an examination bed, and then the bed board of the examination bed is moved, so that the subject moves along with the bed board into an examination area of the nuclear magnetic resonance imaging equipment, and the nuclear magnetic resonance imaging examination can be performed on the part to be examined of the subject. When performing mri examination of a lesion site of a subject, it is sometimes necessary to simultaneously monitor the breathing of the subject.

A typical way to monitor the breathing of a subject is: one strain gauge is arranged on each side of the chest of the subject on the examination bed, and a belt is connected to the strain gauges on the two sides across the chest of the subject. When a subject breathes, the movement of the thorax pulls the belt to be tensioned and loosened, and meanwhile, the stress on the strain gauge connected with the belt changes, so that the resistance value of the strain gauge changes, and the breathing of the subject can be monitored according to the change of the resistance value of the strain gauge.

Therefore, the traditional way for monitoring the breathing of the subject needs to wear more additional components on the subject, which causes the operation flow to be troublesome during monitoring and the experience of the subject to be poor.

Disclosure of Invention

Based on this, it is necessary to provide an examining table aiming at the problems that the traditional way of monitoring the breathing of the subject causes the operation flow to be troublesome and the experience of the subject is poor. The examining table can be used for monitoring the breath of a subject, and no additional component is required to be worn on the subject when the breath of the subject is monitored, so that the operation flow is concise during monitoring, and the experience of the subject is improved.

a bed having a support surface for supporting a subject;

the flexible bag is arranged on the bed body, and when fluid is filled into an inner cavity of the flexible bag, the flexible bag can protrude out of the supporting surface; and

and the pressure monitoring device is connected with the flexible bag and is used for monitoring the pressure in the flexible bag.

According to the examination bed, the fluid is filled in the flexible bag and can protrude out of the supporting surface, so that when a subject lies on the supporting surface of the examination bed, the flexible bag is pressed, the movement of the thorax of the subject during respiration can cause the pressure of the subject on the flexible bag to change, and the pressure value in the flexible bag can synchronously change along with the respiration of the subject. Therefore, according to the change signal of the pressure value in the flexible bag monitored by the pressure monitoring device, the change cycle of the pressure value in the flexible bag is analyzed, and the breathing rate of the subject can be obtained. Therefore, when the examination bed is used for monitoring the breath of the testee, the testee can lie on the supporting surface of the bed body without wearing an additional component on the testee, so that the operation flow during monitoring is simple and the experience of the testee is improved.

Referring to fig. 1 in conjunction with fig. 2, an embodiment of the present application provides an examining table 100. The examination couch 100 includes: a bed 110, a flexible bladder 120, and a pressure monitoring device 160.

The bed 110 has a support surface 110 a. In use of the examination couch 100, the support surface 110a is oriented vertically upward for supporting a subject (not shown).

The flexible bag 120 is disposed on the bed 110. The flexible bladder 120 has an inner lumen 101. The inner chamber 101 of the flexible bladder 120 is used to fill with a fluid such that a certain pressure is present within the flexible bladder 120. The fluid is for example a gas or a liquid.

The material used for the flexible bladder 120 may be rubber, flexible polymer, etc. Since the flexible bladder 120 is made of a flexible material, the flexible bladder 120 can change its volume according to the pressure of the fluid filled therein, and thus can expand or contract.

As shown in FIG. 1, when the interior chamber 101 of the flexible bladder 120 is filled with a fluid, the fluid expands the volume of the flexible bladder 120 so that the flexible bladder 120 protrudes from the support surface 110 a. The protruding direction of the flexible bag 120 protruding from the supporting surface 110a is along the direction Y of the supporting surface 110 a.

A pressure monitoring device 160 is coupled to flexible bladder 120 and is used to monitor the pressure within flexible bladder 120. It will be appreciated that when the fluid filled within the interior chamber 101 of the flexible bladder 120 is a gas, the pressure monitoring device 160 may be a gas pressure monitoring device for monitoring the pressure of the gas within the flexible bladder 120. The air pressure monitoring device is, for example, a barometer, an air pressure sensor, or the like. When the fluid filled in the inner chamber 101 of the flexible bladder 120 is a liquid, the pressure monitoring device 160 may employ a hydraulic pressure monitoring device for monitoring the hydraulic pressure within the flexible bladder 120. The hydraulic pressure monitoring device is, for example, a hydraulic pressure gauge, a hydraulic pressure sensor, or the like.

When the examination couch 100 is used for monitoring the respiration of a subject, first, the inner chamber 101 of the flexible bladder 120 is filled with a fluid, so that a certain pressure is provided in the flexible bladder 120 and the flexible bladder 120 protrudes from the support surface 110 a. Next, the subject is laid on the support surface 110a of the examination bed 100, and the chest position of the subject is made to correspond to the position of the flexible bladder 120.

Since the flexible bladder 120 protrudes from the supporting surface 110a, the subject presses the flexible bladder 120 when lying on the supporting surface 110a of the examination bed 100. Since the chest position of the subject corresponds to the position of the flexible bladder 120, the movement of the thorax of the subject during respiration causes the pressure of the subject on the flexible bladder 120 to change, and thus the pressure value in the flexible bladder 120 changes synchronously with the respiration of the subject. Therefore, the breathing rate of the subject can be obtained by analyzing the variation cycle of the pressure value in the flexible bag 120 according to the variation signal of the pressure value in the flexible bag 120 monitored by the pressure monitoring device 160. Therefore, when the examination couch 100 is used for monitoring the breathing of the subject, the subject can lie on the supporting surface 110a of the couch body 110 without wearing additional components on the subject, so that the operation flow during monitoring is simple and the experience of the subject is improved.

In addition, when the heart of the subject beats, the movement of the heart generates a recoil effect in the chest, and the movement of the blood generates a recoil effect in the whole body, so that the gravity of the heart of the subject changes when the heart of the subject shoots blood. The change of the self-gravity caused by the heart beat of the subject also causes the pressure of the subject on the flexible bag 120 to change, so that the pressure value in the flexible bag 120 also changes synchronously with the heart beat of the subject. Thus, the signal of the change in pressure value within the flexible bladder 120 monitored by the pressure monitoring device 160 can be affected by both the respiration and the cardiac activity of the subject. Generally, the human body has a respiration rate of 12 to 20 times/min and a heart rate of 55 to 70 times/min at rest. Therefore, the respiratory wave signal and the cardioblast signal can be separated by filtering the variation signal of the pressure value in the flexible bag 120 monitored by the pressure monitoring device 160 with the band pass filters having the pass bands of 0.2Hz-0.3Hz and 0.75Hz-1.5Hz, respectively. The respiration rate of the subject can be obtained according to the variation cycle of the respiratory wave signal, and the heart rate of the subject can be obtained according to the variation cycle of the cardiac shock wave signal.

In other embodiments, when the subject lies on the supporting surface of the examination bed, the position of the abdomen of the subject may correspond to the position of the flexible bag, and the movement of the abdomen of the subject during respiration may cause the pressure of the subject on the flexible bag to change, so that the pressure value in the flexible bag may change synchronously with the respiration of the subject. Therefore, the respiration rate of the subject can also be obtained by analyzing the variation cycle of the pressure value in the flexible bladder according to the variation signal of the pressure value in the flexible bladder monitored by the pressure monitoring device 160.

Referring to fig. 1, in one embodiment, a groove 102 is formed on the supporting surface 110a, and the flexible bag 120 is disposed in the groove 102.

Specifically, flexible bladder 120 is disposed within recess 102. in one aspect, recess 102 provides space for flexible bladder 120 to fit and facilitates positioning of flexible bladder 120 during installation. On the other hand, as mentioned above, when the inner cavity 101 of the flexible bladder 120 is filled with the fluid, the fluid will increase the volume of the flexible bladder 120 and expand, so that the flexible bladder 120 can protrude from the supporting surface 110 a. In the present embodiment, since the groove 102 can accommodate the flexible bag 120, the flexible bag 120 only needs to partially protrude from the supporting surface 110a, so that the body of the subject can be relatively flat when lying on the supporting surface 110 a.

Further, in one particular embodiment, the dimension of the portion of flexible bladder 120 that is located within recess 102 is greater than the dimension of the portion of flexible bladder 120 that protrudes from support surface 110a along support surface 110a in the direction Y. From the perspective of fig. 1, that is, the height of the portion of the flexible bag 120 located in the groove 102 is greater than the height of the portion of the flexible bag 120 protruding from the supporting surface 110a, so that the protruding degree of the portion of the flexible bag 120 protruding from the supporting surface 110a is further smaller, and the body of the subject lying on the supporting surface 110a is flatter.

In other embodiments, the supporting surface may not have a groove, and the flexible bag is directly disposed on the supporting surface, so that the whole flexible bag protrudes from the supporting surface.

Referring to fig. 2, in one embodiment, the examination couch 100 further comprises a pressure adjustment device 170, the pressure adjustment device 170 being connected to the flexible bladder 120 for adjusting the pressure within the flexible bladder 120 such that the flexible bladder 120 is capable of maintaining a desired pressure value. The pressure regulating device 170 may be a pneumatic pressure regulating device or a hydraulic pressure regulating device. For example, when the fluid is a gas, the pressure adjustment device 170 may be a gas pressure adjustment device. When the fluid is a liquid, the pressure adjustment device 170 may employ a hydraulic adjustment device.

In particular, the pressure regulating device 170 may be a pressure regulating pump, such as a pneumatic pump or a hydraulic pump. When the fluid is gas, the air pressure adjusting device can adopt an air pressure pump. When the fluid is a liquid, the hydraulic adjustment device may employ a hydraulic pump.

Referring to fig. 1, in an embodiment, the bed 110 includes: a bed board 111 and a bed frame 112. In actual use, the frame 112 is located below the top board 111 to support the top board 111. The support surface 110a is a surface of the top board 111, and the subject is supported on the top board 111. Specifically, in the present embodiment, the groove 102 is disposed on the bed plate 111, and the flexible bag 120 is disposed in the groove 102, that is, the flexible bag 120 is disposed on the bed plate 111.

The bed plate 111 is movable relative to the bed frame 112 in a first direction X perpendicular to the orientation Y of the support surface 110 a. Specifically, in actual use, the orientation Y of the supporting surface 110a is vertically upward, and then the first direction X is a horizontal direction. That is, the top board 111 can move in the horizontal direction with respect to the frame 112.

When magnetic resonance imaging is required, the subject may be placed on the bed plate 111. By moving the bed base 111 in the first direction X while keeping the bed base 112 stationary, the subject and the flexible bladder 120 can be moved together with the bed base 111 into the examination region of the mri apparatus. Because the subject and the flexible bag 120 can move together with the bed plate 111 to the examination area of the mri apparatus, the subject can also test the respiration rate and the heart rate through the flexible bag 120 and the pressure monitoring device 160 while performing the mri examination.

Of course, it is understood that the examining table 100 of the present embodiment can also be used to transfer the subject to the examining region of other medical equipment, such as a direct Digital Radiography (DR), a Computed Tomography (CT) apparatus, etc., without being limited to a magnetic resonance imaging (mri) apparatus, so that the subject can also test the respiration rate and the heart rate through the flexible bladder 120 and the pressure monitoring device 160 while performing other medical examinations.

Referring to fig. 1, in one embodiment, the examination table 100 further includes a flexible tube 130. One end of the flexible tube 130 is connected to the flexible bag 120, and the other end of the flexible tube 130 is connected to the pressure monitoring device 160, so that the fluid in the flexible bag 120 can flow into the flexible tube 130, and the pressure monitoring device 160 can monitor the pressure value in the flexible bag 120 through the flexible tube 130.

Specifically, the flexible tube 130 may be made of rubber, flexible polymer, or the like. As shown in fig. 1, in the present embodiment, one end of the flexible tube 130 is connected to the flexible bag 120, and the other end of the flexible tube 130 penetrates the bed board 111 and the bed frame 112 in sequence and is connected to the pressure monitoring device 160. The pressure monitoring device 160 is disposed in the control chamber 140 disposed on the bed frame 112, but the pressure monitoring device 160 may be disposed at other positions on the bed frame 112.

Since the flexible bag 120 and the pressure monitoring device 160 are connected by the flexible tube 130, the flexible bag 120 and the pressure monitoring device 160 can move relatively by the movement of the flexible tube 130, and the connection can be maintained while the relative movement is performed.

During the process that the subject moves together with the bed plate 111 along the first direction X into the examination area of the mri apparatus, the pressure monitoring device 160 and the bed frame 112 may be disposed outside the examination area and both may be kept stationary, at this time, the flexible bag 120 may move relative to the pressure monitoring device 160 through the movement of the flexible tube 130, so that the flexible bag 120 may move together with the bed plate 111 and the subject along the first direction X into the examination area of the mri apparatus. Therefore, when the flexible bag 120 moves along with the bed plate 111 and the subject along the first direction X to the examination area of the mri apparatus, the pressure monitoring device 160 does not need to enter the examination area of the mri apparatus, so that the influence of the metal material adopted by the pressure monitoring device 160 on the magnetic field environment of the mri apparatus is avoided, and the flexible bag 120 can still be connected with the pressure monitoring device 160 through the connecting pipe 130.

In other embodiments, the pressure monitoring device 160 may be disposed on the flexible bladder or on the bed plate when the flexible bladder is not required for use in a magnetic field environment.

In one embodiment, pressure adjustment device 170 is coupled to flexible bladder 120 via flexible tube 130. One end of the flexible tube 130 is connected to the flexible bladder 120, and one end of the flexible tube 130 remote from the flexible bladder 120 is connected to the pressure adjustment device 170.

Specifically, in the present embodiment, the pressure adjustment device 170 shares the same flexible tube 130 with the pressure monitoring device 160. Examination table 100 also includes a three-way valve (not shown). The three-way valve is disposed at an end of the flexible tube 130 remote from the flexible bladder 120. The three-way valve has a first port, a second port, and a third port. The first port is communicated with the pressure adjusting device 170, the second port is communicated with the pressure monitoring device 160, and the third port is communicated with one end of the flexible tube 130 far away from the flexible bag 120, so that the pressure adjusting device 170 and the pressure monitoring device 160 can share the same flexible tube 130 to be connected with the flexible bag 120.

In the present embodiment, the pressure adjusting device 170 is disposed in the control cabin 140 disposed on the bed frame 112, but the pressure adjusting device 170 may be disposed at other positions of the bed frame 112.

During the process that the subject moves together with the bed plate 111 along the first direction X into the examination area of the mri apparatus, the pressure adjustment device 170 and the bed frame 112 may be disposed outside the examination area and both may be kept stationary, at this time, the flexible bag 120 may move relative to the pressure adjustment device 170 through the movement of the flexible tube 130, so that the flexible bag 120 may move together with the bed plate 111 and the subject along the first direction X into the examination area of the mri apparatus. Therefore, when the flexible bag 120 moves along with the bed plate 111 and the subject along the first direction X to the examination area of the mri apparatus, the pressure adjustment device 170 does not need to enter the examination area of the mri apparatus, thereby avoiding the influence of the metal material adopted by the pressure adjustment device 170 on the magnetic field environment of the mri apparatus, and the flexible bag 120 can still be connected with the pressure adjustment device 170 through the connection pipe 130.

In other embodiments, the pressure adjusting device 170 and the pressure monitoring device 160 may be respectively configured with a flexible tube, and the two flexible tubes are respectively connected to the flexible bag through the corresponding flexible tubes, so that the pressure adjusting device 170 can adjust the pressure of the flexible bag, and the pressure monitoring device 160 can monitor the pressure of the flexible bag. In addition, the end of the flexible tube corresponding to the pressure adjustment device 170, which is far away from the flexible bag, may be sequentially threaded through the bed board and the bed frame and then connected to the pressure adjustment device 170.

In other embodiments, the pressure monitoring device 160 may be disposed on the bed plate when the bed plate is not required to be used in a magnetic field environment.

Referring to fig. 1, in an embodiment, the examination table 100 further includes: a towline trough 150. The towline slot 150 is arranged on the bed board 111 and/or the bed frame 112, and the flexible pipe 130 is arranged through the towline slot 150.

Specifically, as shown in fig. 1, in the present embodiment, a part of the towline groove 150 is disposed in the bedplate 111, and another part is disposed in the frame 112. Because the flexible tube 130 is inserted into the towline groove 150, the towline groove 150 can limit the flexible tube 130 to keep the regularity of the flexible tube 130 in the process that the flexible bag 120 moves relative to the pressure monitoring device 160 and/or the pressure adjusting device 170 through the movement of the flexible tube 130. Moreover, the flexible pipe 130 is arranged in the towline groove 150 in a penetrating manner, so that the flexible pipe can be protected by the towline groove 150, and abrasion caused by friction between the flexible pipe 130 and the bed body 110 can be prevented.

Further, as shown in fig. 1, the towline slot 150 includes a transverse segment 151 extending in the first direction X and a longitudinal segment 152 extending in the second direction Y. The second direction Y is the orientation of the support surface 110 a. Wherein at least two segments of the transverse segments 151 are arranged at intervals along the second direction Y. Adjacent transverse segments 151 are connected by longitudinal segments 152. Through setting up two sections at least horizontal sections 151 and being used for connecting the vertical section 152 of adjacent horizontal section 151 for tow chain line groove 150 forms the shape that the multistage is buckled, thereby tow chain line groove 150 can have longer total length, then can make the length of wearing to locate the flexible pipe 130 of tow chain line groove 150 longer, and then makes things convenient for flexible bag 120 to remove for pressure monitoring device 160 and/or pressure adjustment device 170. In addition, at least two sections of transverse sections 151 and longitudinal sections 152 used for connecting the adjacent transverse sections 151 are arranged, so that the towline groove 150 is formed into a multi-section bent shape, and the installation space of the towline groove 150 is saved.

In particular, in this embodiment, the transverse section 151 is two sections, both of which are disposed within the bed frame 112.

In other embodiments, the towline slot may be disposed in only one of the bed board or the bed frame.

In one embodiment, the examination table 100 further comprises: a tensile layer (not shown). A tensile layer is disposed on an outer surface of flexible bladder 120. The tensile strength of the material used for the tensile layer is greater than the tensile strength of the material used for the flexible bladder 120, thereby improving the tensile property of the flexible bladder 120 and preventing the flexible bladder 120 from excessively expanding.

The tensile layer may be made of a material such as tensile fiber, and the tensile layer may be connected to the outer surface of flexible bladder 120 by, for example, bonding.

In one embodiment, the bed 110 has a first position and a second position along the first direction X. The first and second positions are provided with flexible bladders 120, respectively, each flexible bladder 120 being correspondingly configured with a pressure monitoring device 160. Wherein the first position is adapted to correspond to the chest of the subject and the second position is adapted to correspond to the abdomen of the subject, such that the breathing rate of the chest position and the breathing rate of the abdomen position of the subject can be tested when the subject is lying on the support surface 110a, respectively.
