Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an efficient gynecological examination bed. Background Art
[0002] During gynecological clinical examinations, examination beds, as one of the important medical equipment, are widely used in various gynecological diagnosis and treatment operations. To protect patient privacy and hygiene safety, disposable membranes are usually laid on the surface of the examination bed to avoid cross-infection between patients and keep the examination bed clean.
[0003] However, existing gynecological examination beds still have some shortcomings in terms of membrane replacement and post-use processing: currently most gynecological examination beds use manual methods to replace the membrane, that is, after each patient's examination, the patient or medical staff manually removes the used membrane and replaces it with a new one. This method is not only inefficient, but also increases the workload of the operator.
[0004] Moreover, during the membrane replacement process, the used old membrane is usually discarded directly or temporarily placed in an ordinary trash can, lacking an effective collection and sealing device. Since the membrane may be contaminated with the patient's secretions or other biological contaminants during gynecological examinations, if it is not sealed and processed in time, it is easy to cause the spread of pathogenic microorganisms, increasing the risk of cross-infection during replacement. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide an efficient gynecological examination bed in response to the above-mentioned defects, which can not only automatically replace the membrane cloth on the bed after use without manual collection, thereby reducing the labor intensity of the operator and improving the efficiency of membrane cloth replacement, but also automatically collect and seal the used membrane cloth, thereby effectively preventing the occurrence of medical pollution.
[0006] The technical solution adopted by the present invention to solve its technical problems is: an efficient gynecological examination bed, comprising a mounting frame, a bed body arranged on the mounting frame and a backrest located on one side of the bed body, wherein a film feeding roller and a guide roller are respectively provided on both sides of the bed body, and a film cloth is wrapped around the film feeding roller, and a collecting assembly is provided under the guide roller, wherein the collecting assembly includes a collecting box and a box cover slidably arranged on the upper part of the collecting box, and a cutter is provided on the front side of the box cover, wherein a first transmission mechanism, a second transmission mechanism and a driving mechanism for driving the two to move simultaneously are provided on the mounting frame, the first transmission mechanism is used to drive the film feeding roller and the guide roller to rotate, and the second transmission mechanism is used to drive the box cover to reciprocate along the length direction of the bed body, and the bed body is also provided with a pressure sensor, and the pressure sensor is used to control the driving mechanism to automatically start when the patient gets off the bed body, and the box cover moves accordingly during the process of conveying the film cloth into the collection box to expose the collection box. When the film cloth is collected, the box cover just moves to a position to seal the collection box, and the film cloth is cut by the cutter.
[0007] The working principle of this solution is: when the patient has completed the examination and leaves the bed, the pressure sensor detects that the pressure disappears, triggering the drive mechanism to start automatically, thereby driving the first transmission mechanism and the second transmission mechanism to operate, and the second transmission mechanism drives the film feeding roller and the guide roller to rotate simultaneously, and transports the used membrane cloth downward into the collection box. During the movement of the membrane cloth, the box cover slides along the collection box driven by the second transmission mechanism, exposing the collection box so that the membrane cloth can smoothly enter the collection box. When the membrane cloth is transported to a certain length, the first transmission mechanism drives the box cover to move in the opposite direction. When all the used membrane cloths enter the collection box, the box cover just moves to the position to seal the collection box. During this process, the cutter arranged on the front side of the box cover cuts the membrane cloth, and the used membrane cloths are all put into the collection box, and the collection box is sealed by the box cover.
[0008] Compared with the existing technology, the benefits of this solution are: (1) Through the cooperation of the pressure sensor, the driving mechanism and the first transmission mechanism, the membrane cloth can be automatically replaced after the patient gets off the bed, without the need for manual replacement, thus reducing the workload and improving efficiency; (2) Through the cooperation of the collection box, the box cover, the cutter arranged on the front side of the box cover, the driving mechanism, and the second transmission mechanism, the used old membrane cloth can be directly collected into the collection box and cut off by the cutter, without the need for medical staff to manually collect the replaced membrane cloth. At the same time as the old membrane cloth is cut off, the collection box can be sealed by the box cover, which can effectively prevent medical contamination and cross infection. (3) By starting the driving mechanism, the replacement of the new membrane cloth, the collection of the old membrane cloth, and the sealing of the collection box after the collection are completed can be completed simultaneously. One action can achieve three functions. The structure is reasonable and can further improve the efficiency of the membrane cloth replacement on the gynecological examination bed.
[0009] As a preferred embodiment of the present invention, a placement table is provided in the middle of the mounting frame, the driving mechanism includes a motor assembly arranged on the placement table, a connecting shaft is provided at one end of the output shaft of the motor assembly, the first transmission mechanism includes a first belt respectively installed at both ends on the connecting shaft and the film feeding roller, and a second belt respectively installed at both ends on the connecting shaft and the guide roller; the second transmission mechanism includes a slider arranged on the placement table and connected to the rear side of the box cover, and a connecting rod and a crank for driving the slider to move in the horizontal direction, one end of the crank is fixedly connected to the output shaft of the motor assembly.
[0010] The benefits of this solution are as follows: the output shaft of the motor assembly rotates to drive the connecting shaft and the crank to rotate at the same time, and the rotation of the connecting shaft drives the first belt and the second belt to rotate, thereby driving the film feeding roller and the guide roller to rotate, and transporting the film cloth forward and downward; the rotation of the crank drives the connecting rod to swing, and the swing of the connecting rod drives the slider to move, thereby driving the box cover to move in the direction away from the collection box, exposing the collection box. When a certain length of film cloth is transported into the collection box, that is, after the crank rotates 180°, the box cover moves in the opposite direction. When all the used film cloths enter the collection box, the box cover just moves to the initial position, that is, the position where the collection box is sealed. In this process, the film cloth is cut by a cutter arranged on the front side of the box cover to separate the used film cloth from the new film cloth, and the used film cloth is collected and sealed by the collection box.
[0011] As a preferred embodiment of the present invention, a through groove for slidingly cooperating with the box cover is opened on the rear side of the collection box, the upper side of the box cover is lower than the upper side of the collection box, a slide groove matching the through groove is opened on the side of the placement platform close to the collection box, and a groove connected to the slide groove is opened on the upper side of the placement platform, and the slider is located in the groove.
[0012] The benefit of this solution is that: in the process of moving the box cover to expose the collection box, the box cover moves along the through groove and enters the slide groove under the drive of the slider, and the slide groove limits the movement of the box cover on the placement table; the upper side of the box cover is lower than the upper side of the collection box, so that when the box cover moves to seal the collection box, the cutter can abut against the inner side of the collection box, thereby ensuring that the membrane cloth can be cut.
[0013] As a preferred embodiment of the present invention, the film feeding roller is arranged on the side of the bed close to the backrest, and the mounting frame is provided with a limiting portion on the side close to the guide roller. A gap is left between the limiting portion and the guide roller for the film cloth to pass through, and the inner side of the limiting portion is flush with the inner side of the collection box.
[0014] The benefit of this solution is that: since the membrane cloth passes through the gap between the limiting part and the guide roller, and the inner side of the limiting part is flush with the inner side of the collection box, when the membrane cloth is transported into the collection box, the limiting part plays a role in limiting and guiding the transportation of the membrane cloth, ensuring that the membrane cloth can smoothly enter the collection box.
[0015] As a preferred embodiment of the present invention, the limiting portion includes an upper baffle and a lower baffle arranged in a stepped shape, the inner side of the upper baffle is flush with the inner side of the collection box, and the inner side of the lower baffle is in contact with the outer side of the collection box.
[0016] The benefits of this solution are: the upper baffle is used to guide the transportation of the membrane cloth, and the lower baffle is used to limit the collection box along the length direction of the bed, so as to avoid the collection box from being displaced when the box cover moves toward the collection box to cut the membrane cloth, thereby avoiding the situation where the old membrane cloth cannot accurately enter the collection box.
[0017] As a preferred embodiment of the present invention, a limit plate is provided at one inner end of the lower baffle. Along the length direction of the collecting box, when one side of the collecting box abuts against the limit plate, the two end faces of the guide roller are respectively aligned with the two inner walls of the collecting box, and the width of the membrane cloth is smaller than the length of the guide roller.
[0018] The benefit of this solution is that: when placing the collection box, first place the collection box on the side away from the limit plate, and make the front and rear sides of the collection box contact the inner side of the lower baffle and one side of the mounting frame respectively, and then move the collection box toward the limit plate until one side of the collection box abuts the inner side of the limit plate. At this time, the two end faces of the guide roller are aligned with the two inner walls of the collection box respectively. Since the width of the membrane cloth is smaller than the length of the guide roller, the cooperation of the lower baffle and the limit plate can make the collection box directly under the guide roller, thereby ensuring that the membrane cloth can be completely transported into the collection box.
[0019] As a preferred embodiment of the present invention, the slider is detachably connected to the box cover, a second groove is opened on the rear side of the box cover, and card slots are symmetrically provided on the two opposite inner walls of the second groove. Elastic card blocks for engaging with the card slots are respectively provided on both sides of the slider.
[0020] The benefit of this solution is that the slider is detachably connected to the box cover. When the collection box is filled with the membrane cloth, the elastic card block is pinched to withdraw it from the card slot, and the slider is separated from the box cover. This allows medical staff to remove the collection box in a sealed state by the box cover, avoiding the collection box being in an open state during the recycling process, which may easily cause pollution to the environment.
[0021] As a preferred embodiment of the present invention, a connecting strip is provided on the rear side of the box cover, a connecting hole is opened on the connecting strip, and a clamping column for engaging with the connecting hole is provided on the inner side of the collection box, and the clamping column is located above the box cover.
[0022] The benefit of this solution is that when the membrane cloth in the collection box reaches its capacity and the collection box is sealed by the box cover, the connecting strip provided on the box cover is engaged with the clamping column provided on the inner side of the collection box through the connecting hole to limit the box cover, thereby preventing the box cover with a cutter on the front side from falling off the collection box during the movement of the collection box, thereby reducing safety hazards.
[0023] As a preferred embodiment of the present invention, a cover plate for covering the first belt and the second belt is provided on one side of the bed, a mounting seat for supporting the connecting shaft is provided on the placement table, and the other end of the connecting shaft is provided on the cover plate.
[0024] The benefits of this solution are: the first belt and the second belt are covered by the cover plate to prevent them from being exposed to the outside and unsightly; the cover plate also serves to install the guide roller, film feeding roller and connecting shaft; the connecting shaft is supported by the mounting seat arranged on the placement table, avoiding supporting the connecting shaft by the output shaft of the motor assembly.

The film cloth 18 is laid on the bed 2 through the film inlet and the film outlet. Compared with providing an opening on the bed 2 for the film cloth 18 to pass through, providing the film inlet and the film outlet on the rear side and the bottom of the backrest 3 respectively can avoid causing discomfort to the patient when lying on the bed 2.
[0036] A limiting portion is provided on one side of the mounting frame 1 close to the guide roller 17. A gap is left between the limiting portion and the guide roller 17 for the membrane cloth 18 to pass through. The limiting portion includes an upper baffle 11 and a lower baffle 12 arranged in a stepped shape. A limiting plate 13 is provided at one end of the inner side of the lower baffle 12. A placement platform 9 is provided in the middle of the mounting frame 1, and a slide groove 901 is opened on the side of the placement platform 9 close to the guide roller 17.

A mounting seat 19 is provided on it along the width direction of the mounting frame 1, and the mounting seat 19 is located on the side of the first groove 902 close to the cover plate 21.
[0037] In this embodiment, along the length direction of the mounting frame 1 , the sides of the collecting box 4 and the box cover 5 away from the film feeding roller 16 are respectively the front sides thereof, and the sides close to the film feeding roller 16 are respectively the rear sides thereof.
[0038] As attached Figure 1 , Attachment Figure 6 and attached Figure 7 As shown: a collecting assembly is provided below the guide roller 17, and the collecting assembly includes a collecting box 4 and a box cover 5 slidably arranged on the upper part of the collecting box 4. A through groove 401 for slidingly cooperating with the box cover 5 is opened on the rear side of the collecting box 4, and the upper side of the box cover 5 is lower than the upper side of the collecting box 4. Two clamping columns 15 are symmetrically provided on the inner side wall of the rear side of the collecting box 4, and the two clamping columns 15 are both located above the box cover 5.
[0039] When placing the collection box 4, the collection box 4 is inserted between the lower baffle 12 and the mounting frame 1 along its length direction from the side away from the limit plate 13 until one side of the collection box 4 abuts against the limit plate 13. At this time, the inner side of the upper baffle 11 is flush with the inner side of the collection box 4, and the inner side of the lower baffle 12 is in contact with the outer side of the collection box 4 to limit the collection box 4. The two end faces of the guide roller 17 are respectively aligned with the two inner walls of the collection box 4 to ensure that the membrane cloth 18 can smoothly enter the collection box 4.
[0040] The front side of the box cover 5 is provided with a cutter 6, and the rear side of the box cover 5 is provided with a second groove 501. The two opposite inner walls of the second groove 501 are symmetrically provided with card slots 502. The upper part of the rear side of the box cover 5 is symmetrically provided with two connecting strips 14. Both connecting strips 14 are provided with connecting holes for engaging with the card columns 15. When the collection is completed, the connecting strips 14 are passed through the top of the box cover 5 and the connecting holes are engaged with the card columns 15, thereby limiting the box cover 5.
[0041] As attached Figure 3 , Attachment Figure 4 and attached Figure 5 As shown: the mounting frame 1 is provided with a first transmission mechanism 7, a second transmission mechanism 8 and a driving mechanism for driving the two to move simultaneously, the driving mechanism includes a motor assembly 10 arranged on a placement table 9, and one end of the output shaft of the motor assembly 10 is provided with a connecting shaft 23, which is supported by a mounting seat 19, and the other end of the connecting shaft 23 is installed on the cover plate 21.
[0042] The first transmission mechanism 7 is used to drive the film feeding roller 16 and the guide roller 17 to rotate. Specifically, the first transmission mechanism 7 includes a first belt 701 installed at both ends on the connecting shaft 23 and the film feeding roller 16, and a second belt 702 installed at both ends on the connecting shaft 23 and the guide roller 17. Pulleys are provided on the connecting shaft 23, the film feeding roller 16 and the guide roller 17. The first belt 701 and the second belt 702 are covered by the cover plate 21. In this embodiment, an avoidance hole 22 for avoiding the leg support 20 is opened on the upper side of the cover plate 21 to avoid obstruction to the installation of the leg support 20. Figure 2 shown.
[0043] The second transmission mechanism 8 is used to drive the box cover 5 to reciprocate along the length direction of the bed body 2. Specifically, the second transmission mechanism 8 includes a slider 801 arranged on the placement table 9 and connected to the rear side of the box cover 5, and a connecting rod 802 and a crank 803 for driving the slider 801 to move in the horizontal direction. One end of the crank 803 is fixedly connected to the output shaft of the motor assembly 10.
[0044] The slider 801 is detachably connected to the box cover 5, with one end located in the first groove 902. Elastic blocks for engaging with the card slot 502 are respectively provided on both sides of the slider 801. In this embodiment, a connecting block 804 is provided in the vertical direction on the side of the slider 801 away from the box cover 5, and the connecting rod 802 is rotatably connected to one side of the upper part of the connecting block 804 to ensure that there is sufficient spacing between the connecting rod 802 and the crank 803 and the bottom wall of the first groove 902 to avoid interference with the swing of the connecting rod 802 and the rotation of the crank 803.
[0045] The bed 2 is also provided with a pressure sensor. When the patient gets off the bed 2, the pressure sensor detects that the pressure disappears and feeds back the signal to the controller. The controller controls the driving mechanism to start. In the process of transporting the membrane cloth 18 to the collection box 4, the box cover 5 moves accordingly to expose the collection box 4. When the membrane cloth 18 is collected, the box cover 5 just moves to the position to seal the collection box 4, and the membrane cloth 18 is cut by the cutter 6. A time relay is provided in the controller. When all the used membrane cloths 18 are transported to the collection box 4 through the first transmission mechanism 7, the controller controls the driving mechanism to stop working. The pressure sensor and controller in this scheme are existing technologies, so they will not be described in detail here.
[0046] Specific working principle: The collecting box 4 is placed under the guide roller 17, the inner side of the lower baffle 12 contacts the outer side of the collecting box 4, the limiting plate 13 contacts the other side of the collecting box 4 to limit the collecting box 4, the inner side of the upper baffle 11 is flush with the inner side of the collecting box 4, and the two end faces of the guide roller 17 are respectively aligned with the two inner walls of the collecting box 4 to ensure that the membrane cloth 18 can smoothly enter the collecting box 4 during transportation.
[0047] When the patient has finished the examination and leaves the bed 2, the pressure sensor detects that the pressure disappears, triggering the drive mechanism to start automatically, and the output shaft of the motor assembly 10 rotates, driving the crank 803 fixedly connected to the output shaft and the first belt 701 and the second belt 702 installed on the connecting shaft 23 to rotate at the same time. The rotation of the crank 803 drives the connecting rod 802 to swing, and the swing of the connecting rod 802 drives the slider 801 to move in the horizontal direction, thereby driving the box cover 5 to enter the slide groove 901 and move along it, so that the collection box 4 is in an open state; the rotation of the first belt 701 and the second belt 702 drives the film feeding roller 16 and the guide roller 17 to rotate, thereby driving the film cloth 18 to be transported downward.
[0048] The length of the membrane cloth 18 that needs to be replaced each time is certain. When the membrane cloth 18 to be replaced is conveyed halfway downward, the slider 801 just moves to the farthest point of its stroke. At this time, the collection box 4 is fully opened, and then continues to convey the second half of the membrane cloth 18 downward. At this time, the slider 801 moves in the opposite direction, driving the box cover 5 to move in the direction of sealing the collection box 4, and gradually closing the collection box 4. When the membrane cloth 18 is replaced, the motor assembly 10 stops working, and the slider 801 just moves to the nearest point of its stroke. At this time, the box cover 5 abuts against the inner side of the collection box 4, sealing the collection box 4. In the process of the box cover 5 abutting against the inner side of the collection box 4, the cutter 6 located on the front side of the box cover 5 cuts off the membrane cloth 18, and the cut membrane cloth 18 falls into the collection box 4, and the membrane cloth 18 is collected by the collection box 4.
[0049] When the membrane cloth 18 in the collection box 4 reaches its capacity, pinch the elastic block to withdraw the slider 801 from the card slot 502, separate the slider 801 from the box cover 5, and then engage the connecting strip 14 set on the box cover 5 with the card column 15 set on the inner side of the collection box 4 through the connecting hole to limit the box cover 5, so that the collection box 4 is in a state of being sealed by the box cover 5 when the medical staff takes away the collection box 4, avoiding the collection box 4 being in an open state during the recycling process.

Typical well-known structures and common knowledge technologies in the preferred embodiment are not described in detail here. Ordinary technicians in the relevant field can, under the inspiration given by this embodiment, improve and implement the technical solution of the present invention in combination with their own abilities.
