Technical Field

The invention relates to a transportation tool technology for loading and unloading patients, in particular to an infection-preventing medical transfer bed.

Background

At present, a medical transfer bed is used for moving and transferring patients with inconvenient actions before and after a surgery, the patients are transferred to the transfer bed from a sickbed, and then transferred to an operating table or equipment needing examination/treatment from the transfer bed, or the patients are reversely transferred.

The medical transfer bed sold or used in the market at present mainly comprises two parts, wherein one part is a vehicle body used for moving, and the other part is a moving bed plate mechanism used for transversely moving and receiving patients; for example, the medical patient transport cart disclosed in chinese patent No. 98205338.X includes a cart body and a transport bed top (moving bed plate mechanism) which is composed of transport rollers, driven rollers, and transport cloth belts mounted on the transport rollers and the driven rollers, and the transport bed top can be horizontally translated back and forth under the action of a motor. Also, as disclosed in chinese patent 200610052776.3, "medical patient transfer cart", the moving bed plate mechanism employs a double-layer combination structure of an upper moving bed/upper moving cloth and a lower moving bed/lower moving cloth, and specifically includes a cloth winding shaft frame, a cloth winding shaft, an end joint seat body, a clutch gear, an upper moving bed/upper moving cloth, a lower moving bed/lower moving cloth, and the like.

However, these medical transfer beds have the following disadvantages:

1. problem of hygiene

The transmission strap or the upper and lower moving cloth is directly contacted with the body of a patient, the cloth cover is easy to be dirty and comprises stains such as blood stains, human body exudate, treatment medicine exudate and the like, because the transmission strap or the upper and lower moving cloth is the annular closed transmission cloth, the transmission cloth is hidden in a machine and is difficult to clean and replace, the disassembly and assembly workload of replacing the transmission cloth is not inferior to that of assembling a new machine, and therefore, the problem of the dirty cloth cover cannot be solved. Although the problem of cross infection can be solved by changing the upper and lower moving cloths once every time a patient is transported, the method is not practical, and after the medical equipment is disassembled, the professional is required to debug the equipment again, so that the time is long, and the method is not an optimal solution. In order to avoid cross infection between patients caused by the fact that different patients use the same transfer trolley, the transfer bed capable of automatically laying isolation cushions needs to be designed.

2. Structural problems

The transmission cloth belt (Chinese patent 98205338.X) or the upper moving cloth (Chinese patent 200610052776.3) is driven by the driving rubber roller to rotate, so that the transmission cloth belt or the upper moving cloth sleeved on the rubber roller is driven to transversely move back and forth to be close to or far away from an operating table/sickbed, and as the transmission of the cloth cover needs a certain tension force, the tension degree of the cloth cover needs to be adjusted after long-term use, the cloth cover needs to be replaced when being stretched to a certain degree, otherwise, the guardrails arranged at the two sides of the vehicle body cannot be closed; the cloth cover of the structure is easy to move left and right and needs to be debugged; in addition, the arrangement of the rubber roller can cause many problems, for example, the gap existing between the rubber roller 15 and the end connector seat body 16 in the specification of the medical patient transfer vehicle disclosed in the Chinese patent 200610052776.3, namely the figure 16, is easy to roll clothes into the rubber roller, and the clamp can be used for clamping during the process of transferring patients; and the problems that the rubber roller is aged, the rubber roller needs to be replaced, the running state of the equipment needs to be debugged again and the like exist.

For example, the transmission mechanism of the chinese patent 200610052776.3 adopts a clutch for transmission, and the clutch adopts a mechanical control structure in which two clutch gears are engaged and disengaged, and has the disadvantages of complicated design structure and easy occurrence of failure; particularly, when the clutch part needs to be combined, when the two teeth of the two clutch gears are not coordinated, the combination is not smooth, and when the clutch part needs to be separated, under the condition that the two teeth are meshed, the separation resistance exists, so that the difference of the moving and the positioning is large, and the patient can not be completely transferred.

In addition, the transmission cloth belt or the upper and lower moving cloth is annular closed transmission cloth which is in direct contact with the body of the patient and is a main part for directly receiving and delivering the patient; due to the requirement of medical sanitation, cloth interfaces crack easily caused by the disinfection of cloth surfaces of the transmission cloth belts or the up-and-down moving cloth, and the structural strength is not enough.

3. Safety problem

For example, in the medical patient transfer cart in chinese patent 200610052776.3, the driving mechanism drives the rubber roller to rotate, so that there is a problem that the transmission cloth sleeved on the rubber roller moves back and forth, which may cause a patient to collide with the end connector base 16 due to misoperation, or even fall to the frame of the transfer bed across the end connector base 16. Under the normal state, when a person lies on the transmission cloth, the driving mechanism stops driving the rubber roller to rotate, the transmission cloth is in a static state, and the person only needs to move the up-down moving plate to complete receiving and conveying to a required position. If a patient is on the transfer bed, the patient may hit the end connector base 16 by pressing a button inserted into the bed by mistake, or even fall to the bed frame of the transfer bed across the end connector base 16, resulting in a medical accident.

Preferably, the locking bar driving mechanism is selected from one or a combination of more than two of a motor, a ratchet wheel, a brake mechanism and an electromagnetic device.

Compared with the prior art, the invention has the beneficial effects that:

(1) one of the core points of the invention is that the isolation pad laying mechanism is arranged, when a moving bed plate mechanism of the transfer bed receives a patient and extends out of the up-down moving plate, the upper isolation pad fixed on the locking strip is simultaneously involved between the patient and the upper moving cloth along with the extension of the up-down moving plate, so that the patient is isolated from the upper moving cloth; when the moving bed plate mechanism receives a patient and needs to retract the upper and lower moving plates, the locking strip is unlocked and locked, the upper isolation pad moves synchronously along with the upper and lower moving plates and the upper moving cloth and is always arranged between the patient and the upper moving cloth, so that bloodstains or treatment medicines on the patient cannot pollute the upper moving cloth due to the isolation of the upper isolation pad, the upper moving cloth cannot be polluted due to the patient receiving, and the risk of cross infection among the patients is reduced. In addition, when a moving bed plate mechanism of the transfer bed receives a patient and extends out of the upper and lower moving plates, the lower isolation pad fixed on the receiving and delivering side of the frame is simultaneously rolled between the lower moving cloth and the operating bed along with the extension of the upper and lower moving plates, and the lower moving cloth cannot be polluted by blood or treatment medicines remained on the operating bed; when the moving bed plate mechanism receives a patient and needs to withdraw the upper and lower moving plates, the lower isolation pad is left on the operating bed, so that blood or treatment medicines remained on the operating bed can not pollute the transfer bed due to the isolation of the lower isolation pad, the sanitary standard of the operating bed during secondary use is ensured, and the risk of cross infection among patients is reduced.

When a moving bed plate mechanism of the transfer bed sends a patient to extend out of the up-and-down moving plate, the patient and the upper isolation pad synchronously and transversely move along with the extension of the up-and-down moving plate; after the patient is sent to the sick bed top, loosen the last isolation pad of fixing on the locking strip, when the moving bed board mechanism of transporting the bed withdraws upper and lower movable plate after sending the people, go up the isolation pad and stay between patient and the sick bed, guaranteed the isolated state between patient and the sick bed, reduce infected risk.

In general, the infection-preventing medical transfer bed is provided with the isolation pad laying mechanism, so that the upper isolation pad can ensure that the upper moving cloth cannot be polluted from beginning to end in the processes of receiving and sending patients, and meanwhile, after the patients are sent back to the sickbed, the upper isolation pad is synchronously left on the sickbed, and the sanitary isolation between the patients and the sickbed can also be realized. The lower isolation pad can ensure that the lower movable cloth is not polluted by blood or treatment medicines remained on the operating bed in the process of receiving a patient, and meanwhile, when the patient is received to the transfer bed, the lower isolation pad is synchronously remained on the operating bed to isolate an infection source.

(2) The second core of the invention is that the locking strip is arranged on the upper moving cloth longitudinally and fixed on the upper moving cloth, and the locking strip is driven by the locking strip driving mechanism to move transversely so as to draw the upper moving cloth to move transversely back and forth on the upper moving plate; when the moving bed plate mechanism receives a patient and needs to retract the upper and lower moving plates and send the patient and needs to extend the upper and lower moving plates (namely when the upper moving plate loads a patient), the upper and lower moving plates move transversely under the driving of the moving bed driving mechanism, the locking strip driving mechanism drives the locking strip and the upper moving plate to move synchronously and transversely, the patient lying on the upper moving plate and the locking strip are relatively static, the friction force generated by the lower moving cloth in relative rotation to the lower moving plate is overcome in the process, the friction force at the contact surface of the upper and lower moving cloth is overcome, the upper moving plate, the upper moving cloth and the patient are relatively static, the lower moving cloth moves relative to the lower moving plate and the upper moving plate, but the contact part of the lower moving cloth and the sickbed surface of the sickbed is still relatively static, the resistance is still small, and the problem. When the moving bed plate mechanism is used for receiving a patient and needs to extend out of the upper and lower moving plates, and sending the patient and needs to retract the upper and lower moving plates, the locking strip driving mechanism self-locks the locking strip to fix the locking strip at an initial position, at the moment, the upper moving plate and the lower moving plate simultaneously move forwards and backwards and transversely (the forward transverse movement means that the upper and lower moving plates are gradually inserted between the patient and a sickbed, and the backward transverse movement means that the upper and lower moving plates are gradually withdrawn between the patient and the sickbed), the lower moving cloth moves relative to the lower moving plate, the contact part of the lower moving cloth and the sickbed/operating bed is kept relatively static with the bed surface, the binding surfaces of the upper moving cloth and the lower moving cloth are also kept relatively static, and the contact part of the upper moving cloth and the patient is also kept relatively static with the patient, therefore, in the moving plate moving up and down, there is no other relative movement, that is, there is no sliding friction between the movable cloth and the bed surface of the sickbed/patient, so the resistance is very small, and the sickbed and the patient are relatively static with the movable cloth contacting with them, and the bed sheet can ensure that the movable plate is smoothly inserted under the patient, and the bed sheet is not driven, the patient is not pushed, and the patient is not pushed or pulled. The whole receiving and delivering process is very smooth, and the friction force and the resistance are small.

Generally speaking, the invention replaces the mode of conveying cloth by driving the rubber roller to rotate in the prior art with the power mechanism provided with the locking strips and the locking strips, simplifies the structure of the moving bed plate mechanism, and solves the problems related to no rubber roller, such as the problems of no need of adjusting the tensioning of the cloth cover, the shifting of the cloth cover, hair clamping, clothes rolling, the aging of the rubber roller, the need of replacing the rubber roller, the complicated transmission of a clutch, the medical accidents of falling injury caused by misoperation and the like; meanwhile, the patient is delivered more smoothly, compared with the prior art, the resistance and the friction force in the process of delivering the patient are greatly reduced, and the movable plate can be very smoothly inserted under the patient without manual intervention; the movable cloth has no friction coefficient requirement, the movable resistance is smaller, the power consumption is smaller, a driving motor with smaller power can be adopted, the transmission is simpler, the load capacity of the whole vehicle is more favorably improved, and the production cost is more favorably reduced.

(3) The upper moving cloth and/or the lower moving cloth are designed into an open form, so that the requirements of disassembly and replacement can be met, the purpose of preventing infection is achieved, and the strength cannot be influenced after disinfection.
