Examples

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of the present invention, and fig. 2 is an enlarged view of a point a in fig. 1. The present embodiment provides a gynecological cleaning device comprising an expansion structure, a cleaning structure and a control unit 16, said expansion structure being capable of guiding said cleaning structure into the vagina. The cleaning structure can clean and sterilize the vagina. The expansion structure comprises an arc-shaped head body 1 and an expansion body 2, wherein the arc-shaped head body 1 is connected with the cleaning structure, and the expansion body 2 is arranged between the cleaning structure and the arc-shaped head body 1. The arc-shaped head body 1 is a front end guide body which firstly enters the vagina and then guides each part behind the arc-shaped head body into the vagina. The expansion body 2 can perform the expansion or contraction function, and the expansion or contraction function is used for adapting to the size of the vagina of a patient.

In this embodiment, above-mentioned expansion body 2 is inside to have seted up expansion chamber 3, has seted up pressure boost mouth 5 and pressure relief mouth 6 on the expansion body 2, pressure boost mouth 5 and pressure relief mouth 6 all with expansion chamber 3 intercommunication, pressure boost mouth 5 is connected with first pressure boost pipeline 7, pressure relief mouth 6 is connected with pressure relief pipeline 8, all be provided with first control valve 12 on pressure relief pipeline 8 and the first pressure boost pipeline 7, first control valve 12 is connected to the control unit 16. Above-mentioned expansion chamber 3 can realize the inflation of inflation body 2 through pressure boost mouth 5 injection pressure gas, and similarly, above-mentioned expansion chamber 3 also can carry out gas pressure release through pressure release mouth 6, realizes the shrink of inflation body 2. From this, adaptable different patient's vagina size avoids unable effectual jam to the vagina formation, and the washing liquid gets into the uterus and causes the injury to the patient. And the expansion structure can also be prevented from being large in size and causing extrusion injury to patients.

In the present embodiment, the first control valve 12 on the first pressurization line 7 is used for controlling the opening and closing and the flow rate of the first pressurization line 7, so as to control the expansion process of the expansion body 2. The first control valve 12 on the pressure relief pipeline 8 is used for controlling the opening and closing and the flow of the pressure relief pipeline 8, so as to control the contraction process of the expansion body 2. The control unit 16 can intelligently control the opening and closing and the flow of the first control valve 12, so that the expansion or contraction of the expansion body 2 can be accurately controlled, and the problem of inaccuracy caused by manual control is avoided.

In the present embodiment, the radial dimension of the inflatable body 2 is the maximum radial dimension that extends into the vagina of the patient, and the radial dimensions of the other members are all smaller than the radial dimension of the inflatable body 2. The inflatable body 2 will preferentially contact the patient's vagina and thus be subjected to the greatest pressure within the vagina for blocking the vagina to prevent the entry of the cleansing fluid into the uterus.

Consequently, this cleaning device of gynaecology can stretch into the size according to the vagina size in the washing process of gynaecology and adjust, can prevent that the washing liquid from getting into the uterus, can effectually prevent again to cause the extrusion injury to the vagina when washing, brings uncomfortable symptom for the patient, easily causes the condition such as secondary damage to the user to take place.

Referring to fig. 4, in some embodiments of the present embodiment, a plurality of pressure sensors are disposed on the surface of the expansion body 2 at regular intervals, and the plurality of pressure sensors are respectively connected to the control unit 16.

In this embodiment, the pressure sensors may be used to measure the pressure of the surface of the vagina of the patient to different points on the surface of the inflatable body 2 in real time, and the pressure sensors may detect the pressure values received by a plurality of points on the surface of the inflatable body 2, so as to determine whether the inflatable body 2 destructively extrudes the vagina of the patient.

In this embodiment, the control unit 16 includes a microcontroller, which is an integrated circuit chip, and is a small and perfect microcomputer system formed by integrating functions (possibly including a display driving circuit, a pulse width modulation circuit, an analog multiplexer, an a/D converter, and the like) of a central processing unit CPU, a random access memory RAM, a read only memory ROM, various I/O ports, an interrupt system, a timer/counter, and the like with data processing capability onto a silicon chip by using a very large scale integrated circuit technology, and is widely applied in the field of industrial control.

In this embodiment, after the pressure sensors detect the pressure values received by a plurality of points on the surface of the expansion body 2, the pressure sensors respectively transmit the detected pressure information to the microcontroller, and the microcontroller can determine whether the pressure value received by the expansion body 2 exceeds the maximum rated pressure value according to logic analysis, and if the pressure value exceeds the maximum rated pressure value, the microcontroller controls the first control valve 12 on the pressure relief pipeline 8 to open for pressure relief. During the pressure relief process, the expansion body 2 contracts to adapt to the size of the vagina of the patient due to the discharge of the gas pressure in the expansion cavity 3. In the process of shrinking the expansion body 2, the pressure applied to the expansion body 2 is gradually reduced, the pressure sensor transmits the detected pressure information to the microcontroller in real time, and after the microcontroller judges that the pressure value applied to the expansion body 2 is lower than the maximum rated pressure value according to logic analysis, the microcontroller controls the first control valve 12 of the pressure relief pipeline 8 to be closed.

Similarly, when the microcontroller can judge according to logic analysis that the pressure value that the expansion body 2 received is lower than the minimum rated pressure value, the microcontroller controls the first control valve 12 on the first pressure pipeline 7 to open, and the first pressure pipeline 7 inflates the expansion cavity 3, so that the expansion body 2 is expanded continuously. And in the continuous expansion process of the expansion body 2, the pressure sensor continuously detects the pressure value of the surface of the expansion body 2 and transmits the pressure information to the microcontroller in real time. Because the pressure applied to the expansion body 2 in the vagina is increased after the expansion body 2 is expanded, when the microcontroller judges that the pressure value applied to the expansion body 2 is greater than the minimum rated pressure value according to logic analysis, the microcontroller controls the first control valve 12 on the first pressurization pipeline 7 to close.

In this embodiment, the maximum rated pressure value is a minimum pressure value for determining that the inflatable body 2 has damaged the vagina, and the minimum rated pressure value is a maximum pressure value for determining that the inflatable body 2 and the vagina cannot form effective occlusion. The radial dimensions of the expansion body 2 described above are therefore just suitable when the detected pressure value is between the maximum and minimum nominal pressure values.

In this embodiment, after the pressure values detected by the pressure sensors are transmitted to the microcontroller, the arithmetic mean algorithm is used to obtain the average value by means of weighted mean, and the microcontroller compares and determines the average value with the maximum rated pressure value and the minimum rated pressure value.

The second control valve 15 is controlled by the control unit 16, and the second control valve 15 can be opened or closed to control the spraying or stopping of the cleaning liquid.

Referring to fig. 1, in some embodiments of the present invention, a stabilizing rod 4 is disposed in the expansion cavity 3, and the stabilizing rod 4 is connected to the arcuate head body 1 and the connecting cylinder 10, respectively. Because the expansion body 2 has the elastic expansion and contraction functions, it has no rigidity, which may result in the rigid connection between the connecting cylinder 10 and the arc-shaped head body 1 in the cleaning structure, and thus the arc-shaped head body 1 cannot be effectively controlled. Therefore, the stabilizing rod 4 of the present embodiment is used to realize the rigid connection between the arcuate head body 1 and the connecting cylinder 10.

Referring to fig. 1, in some embodiments of the present invention, a handheld portion 11 is disposed on the cleaning structure, and the handheld portion 11 is located at an end away from the expanding structure.

In the using process, the image sensor can detect the situation in the vagina, so that the diagnosis of medical staff is facilitated, and meanwhile, the monitoring can be carried out, so that the arc-shaped head body 1 is prevented from reaching the uterus due to too much penetration.

In some embodiments of this embodiment, the outer surfaces of the extension structure and the cleaning structure are provided with a buffer layer (not shown). In this embodiment, the buffer layer can play a role in buffering, and prevent the outer surfaces of the extension structure and the cleaning structure from directly contacting the vagina of the patient and damaging the vagina of the patient.

When the vagina-opening device is used, the arc-shaped head body 1 enters the vagina of a patient by holding the holding part, and the arc-shaped head body 1 guides the subsequent components such as the connecting cylinder 10 and the like to enter the vagina. And then starting the control unit 16, after the pressure sensors detect the pressure values received by a plurality of points on the surface of the expansion body 2, respectively transmitting the respective detected pressure information to the microcontroller, wherein the microcontroller can judge whether the pressure value received by the expansion body 2 exceeds the maximum rated pressure value according to logic analysis, and if the pressure value exceeds the maximum rated pressure value, the microcontroller controls the first control valve 12 on the pressure relief pipeline 8 to be opened for pressure relief. During the pressure relief process, the expansion body 2 contracts to adapt to the size of the vagina of the patient due to the discharge of the gas pressure in the expansion cavity 3. In the process of shrinking the expansion body 2, the pressure applied to the expansion body 2 is gradually reduced, the pressure sensor transmits the detected pressure information to the microcontroller in real time, and after the microcontroller judges that the pressure value applied to the expansion body 2 is lower than the maximum rated pressure value according to logic analysis, the microcontroller controls the first control valve 12 of the pressure relief pipeline 8 to be closed.

And in the continuous expansion process of the expansion body 2, the pressure sensor continuously detects the pressure value of the surface of the expansion body 2 and transmits the pressure information to the microcontroller in real time. Because the pressure applied to the expansion body 2 in the vagina is increased after the expansion body 2 is expanded, when the microcontroller judges that the pressure value applied to the expansion body 2 is greater than the minimum rated pressure value according to logic analysis, the microcontroller controls the first control valve 12 on the first pressurization pipeline 7 to close. Thereby, the expansion body 2 can be adjusted to fit the size of the patient by expansion or contraction of the expansion body 2. Then, the on-off key of the second control valve 15 is pressed to open the second control valve 15, the second pressurizing pipeline 14 supplies the cleaning liquid into the liquid storage chamber 17, and after the liquid storage chamber 17 is pressurized, the cleaning liquid is sprayed out along the spraying head 9 to treat the patient. After the treatment is finished, the user presses the stop key, the stop key sends a stop instruction, the control unit 16 controls the first control valve 12 on the pressurization pipeline to be closed, and controls the first control valve 12 on the pressure relief pipeline 8 to be opened, so that the expansion body 2 is not completely contracted, the expansion body 2 is not blocked with the inner wall of the vagina any more, the expansion body is convenient to retreat from the body of the patient after the cleaning is finished, and the cleaning is finished.

In summary, embodiments of the present invention provide a gynecological cleaning device, which includes an extension structure, a cleaning structure and a control unit 16, wherein the extension structure can function as a guide to guide the cleaning structure into the vagina. The cleaning structure can clean and sterilize the vagina. The expansion structure comprises an arc-shaped head body 1 and an expansion body 2, wherein the arc-shaped head body 1 is connected with the cleaning structure, and the expansion body 2 is arranged between the cleaning structure and the arc-shaped head body 1. The arc-shaped head body 1 is a front end guide body which firstly enters the vagina and then guides each part behind the arc-shaped head body into the vagina. The expansion body 2 can perform the expansion or contraction function, and the expansion or contraction function is used for adapting to the size of the vagina of a patient. Above-mentioned 2 inside expansion chamber 3 of having seted up of the expansion body, seted up pressure boost mouth 5 and pressure release mouth 6 on the expansion body 2, pressure boost mouth 5 and pressure release mouth 6 all communicate with expansion chamber 3, and pressure boost mouth 5 is connected with first pressure boost pipeline 7, and pressure release mouth 6 is connected with pressure release pipeline 8, all is provided with first control valve 12 on pressure release pipeline 8 and the first pressure boost pipeline 7, and first control valve 12 is connected to the control unit 16.

And the expansion structure can also be prevented from being large in size and causing extrusion injury to patients. The first control valve 12 on the first pressurization pipeline 7 is used for controlling the opening and closing and the flow of the first pressurization pipeline 7, so as to control the expansion process of the expansion body 2. The first control valve 12 on the pressure relief pipeline 8 is used for controlling the opening and closing and the flow of the pressure relief pipeline 8, so as to control the contraction process of the expansion body 2. The control unit 16 can intelligently control the opening and closing and the flow of the first control valve 12, so that the expansion or contraction of the expansion body 2 can be accurately controlled, and the problem of inaccuracy caused by manual control is avoided. Consequently, this cleaning device of gynaecology can stretch into the size according to the vagina size in the washing process of gynaecology and adjust, can prevent that the washing liquid from getting into the uterus, can effectually prevent again to cause the extrusion injury to the vagina when washing, brings uncomfortable symptom for the patient, easily causes the condition such as secondary damage to the user to take place.
