Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, specifically to a device for quick replacement of sterile sheets and movable fabrics. Background Technology

[0002] Medical transport carts are used to move and transfer patients who are immobile before or after surgery. They move patients from their beds to transport beds, and then from the transport beds to the operating table or equipment requiring examination / treatment, or vice versa. Especially for patients with wounds or those who have undergone severe spinal, cervical, or thoracic spine surgery, the advent of medical transport carts has reduced the workload of medical staff and avoided the secondary injuries that could result from multiple moves during pre- and post-operative transport, such as aggravating wounds, causing significant pain for the patient and hindering wound healing.

[0003] A search revealed a utility model patent with publication number CN212997068U, which specifically discloses a quick-release structure for a movable cloth used on a transfer cart. The transfer cart has a movable plate; a movable cloth is placed on the movable plate; the movable cloth is wrapped in a ring around the movable plate via the quick-release structure. The quick-release structure includes a movable cloth locking seat and a cloth clamping strip. The cloth clamping strip is fixed to both sides of the movable cloth. The movable cloth locking seat has two first limiting cavities, each of which extends to the bottom of the locking seat with a first cloth outlet notch. The first limiting cavity communicates with the first cloth outlet notch. After the movable cloth with the cloth clamping strip is wrapped around the movable plate, the first limiting cavity of the locking seat is aligned with the cloth clamping strip, so that the cloth clamping strip is inserted and confined within the first limiting cavity of the locking seat. This quick-release structure allows for the quick assembly and disassembly of the upper and lower movable cloths, enabling rapid cloth replacement; it also requires minimal operator skill, and can be performed by general medical personnel.

[0004] Although the aforementioned patent uses a quick-release structure for the movable cloth to facilitate the assembly and disassembly of the upper and lower movable cloths and to quickly replace the movable cloths, existing transfer carts not only have movable cloths but also sterile drapes placed on the patient to prevent wound infection during patient transfer. However, the existing sterile drapes are generally laid and secured manually by medical staff, which greatly increases their workload and reduces their efficiency.

[0005] Therefore, it is necessary to propose a rapid replacement device for sterile sheets and moving fabrics to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for quick replacement of sterile drapes and movable sheets. Through the cooperation of the internal parts of the fixing mechanism, the sterile drape can be clamped and fixed, allowing it to fall off and remain on the patient after transfer to the transfer cart. This improves the work efficiency of medical staff and reduces their workload. It addresses the problem that existing transfer carts not only have movable sheets but also sterile drapes on the patient to prevent wound infection during patient transfer. The current method of sterile drape placement and fixing is generally done manually by medical staff, which greatly increases their workload and reduces their efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-change device for sterile sheets and movable cloths, including a fixing plate, the fixing plate being located at the top of a transfer cart, the top of the fixing plate being rotatably connected to a fixing mechanism that extends through the interior of the fixing plate, and quick-change mechanisms being mechanically fixed on both sides of the fixing plate and slidably connected to the top of the transfer cart.

[0008] The fixing mechanism includes a connecting plate, and there are multiple connecting plates. The multiple connecting plates are rotatably connected to one end of the outer wall of the fixing plate. A clamping plate is mechanically fixed between the multiple connecting plates and fits against the top of the fixing plate. Button magnets are mechanically fixed between the top of the fixing plate and the inner walls of the connecting plates and the clamping plates. The multiple button magnets are attracted to each other by magnetism. Multiple support rods are mechanically fixed inside the fixing plate.

[0009] The quick-change mechanism includes a fixed base, which is slidably connected to the top of the transfer vehicle. A quick-insertion plate is mechanically fixed to the top of the fixed base. A movable seat is sleeved on the top of the fixed base and engages with the outer wall of the quick-insertion plate, and is mechanically fixed to both sides of the fixed plate. Multiple elastic pressure plates are mechanically fixed to both ends of the inner wall of the movable seat and extend through to the outer wall of the quick-insertion plate.

[0010] Preferably, the quick-change mechanism further includes an electric slide table, which is bolted inside the quick-connect plate and extends through the quick-connect plate to the bottom of the fixed base, and is sleeved with the slide rail on the transfer vehicle. The top of the movable seat is threaded with a pull rod.

[0011] Preferably, the connecting plate and the clamping plate are rotatably connected to one end of the fixing plate via a connecting shaft, and the inner wall of the connecting plate and the clamping plate and the top of the fixing plate are provided with mounting grooves that match the button magnets.

[0012] Preferably, the inner wall of the connecting plate and the clamping plate and the top of the fixing plate are provided with a clamping groove that matches the sterile drape, and there is a certain height between the bottom of the fixing plate and the transfer cart.

[0013] Preferably, the outer wall of the quick-connect plate has stepped notches at both ends, the inner wall of the movable seat has stepped grooves that match the stepped notches on the outer wall of the quick-connect plate, and the surface of the stepped notches on the outer wall of the quick-connect plate has slots that match the elastic pressure plate.

[0014] Preferably, the quick-connect plate has a fixing groove inside that matches the electric slide table, and the bottom of the electric slide table and the fixing base both have sliding grooves that match the top slide rail of the transfer vehicle. The top of the pull rod is mechanically fixed with a pull ring.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By using a pull rod to bring the movable seat and the fixed base closer together, the movable seat is fitted onto the outer wall of the quick-connect plate. The outer wall of the quick-connect plate has stepped notches at both ends, and the inner wall of the movable seat has stepped grooves that match the stepped notches on the outer wall of the quick-connect plate, so that the movable seat and the quick-connect plate are initially engaged. At the same time, the surface of the stepped notches on the outer wall of the quick-connect plate has slots that match the elastic pressure plate, so that the elastic pressure plate on the inner wall of the movable seat can fit into the slots, thus completing the quick-installation and fixation of the movable seat on the fixed base, thereby completing the fixation of the fixed plate on the transfer cart, thereby reducing the time for fixing the fixed plate on the transfer cart. Meanwhile, the electric slide table slides on the slide rail at the top of the transfer cart, driving the fixed base to slide, which in turn drives the movable seat to slide, thereby adjusting the fixed plate to slide on the transfer cart.

[0017] 2. Both the connecting plate and the clamping plate are rotatably connected to one end of the fixed plate via a connecting shaft. This allows the connecting plate to be opened and rotated, causing the clamping plate to rotate 90 degrees and separate from the surface of the fixed plate. The sterile drape is then placed on the surface of the fixed plate, and the clamping plate is then placed on top. The rotation of the connecting plate causes the clamping plate to rotate and fit against the surface of the fixed plate. The inner walls of the connecting plate and the clamping plate, as well as the top of the fixed plate, have mounting grooves that match the button magnets. This allows the button magnets on the inner walls of the connecting plate and the clamping plate to attract and adhere to each other, ensuring a tight fit between the clamping plate and the fixed plate surface, thus securing the sterile drape. Simultaneously, after the patient is transferred to the transfer cart, the fixed base slides the fixed plate, causing the sterile drape to move and cover the patient's surface. Opening the clamping plate releases the clamping of the sterile drape, allowing it to automatically fall off and remain on the patient, providing sterile protection. This improves the work efficiency of medical staff and reduces their workload. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The device for quick replacement of sterile sheets and movable fabrics shown includes a fixing plate 1, which is located at the top of the transfer cart. The top of the fixing plate 1 is rotatably connected to a fixing mechanism 2, which extends into the interior of the fixing plate 1. Quick-change mechanisms 3 are mechanically fixed on both sides of the fixing plate 1 and are slidably connected to the top of the transfer cart.

[0028] The fixing mechanism 2 includes a connecting plate 201, and there are multiple connecting plates 201. The multiple connecting plates 201 are rotatably connected to one end of the outer wall of the fixing plate 1. A clamping plate 202 is mechanically fixed between the multiple connecting plates 201 and fits against the top of the fixing plate 1. A button magnet 203 is mechanically fixed between the top of the fixing plate 1 and the inner walls of the connecting plates 201 and the clamping plate 202. The multiple button magnets 203 are attracted to each other by magnetism. Multiple support rods 204 are mechanically fixed inside the fixing plate 1.

[0029] The quick-change mechanism 3 includes a fixed base 301, which is slidably connected to the top of the transfer vehicle. A quick-insertion plate 303 is mechanically fixed to the top of the fixed base 301. A movable seat 302 is sleeved on the top of the fixed base 301 and engages with the outer wall of the quick-insertion plate 303, and is mechanically fixed to both sides of the fixed plate 1. Multiple elastic pressure plates 306 are mechanically fixed at both ends of the inner wall of the movable seat 302 and extend through to the outer wall of the quick-insertion plate 303.

[0030] By cooperating with each other among the internal parts of the quick-change mechanism 3, the fixation plate 1 can be quickly fixed on the transfer cart, and the fixation plate 1 can be easily removed and replaced from the transfer cart. By cooperating with each other among the internal parts of the fixation mechanism 2, the sterile drape can be clamped and fixed, so that after the patient is transferred to the transfer cart, the sterile drape falls off and remains on the patient, thereby improving the work efficiency of medical staff and reducing the workload of medical staff.

[0031] Refer to the instruction manual appendix Figure 1-5 The quick-change mechanism 3 also includes an electric slide 304, which is bolted inside the quick-insertion plate 303 and extends through the quick-insertion plate 303 to the bottom of the fixed base 301, and is sleeved with the slide rail on the transfer vehicle. The top of the movable seat 302 is threaded with a pull rod 305. Through the mutual cooperation between the internal parts of the quick-change mechanism 3, the electric slide 304 can drive the fixed base 301 to move on the transfer vehicle and drive the fixed plate 1 to move.

[0032] Refer to the instruction manual appendix Figure 1-5 The connecting plate 201 and the clamping plate 202 are rotatably connected to one end of the fixed plate 1 via a connecting shaft. The inner walls of the connecting plate 201 and the clamping plate 202 and the top of the fixed plate 1 are provided with mounting grooves that match the button magnet 203. The connecting plate 201 and the clamping plate 202 are rotatably connected to one end of the fixed plate 1 via a connecting shaft, which makes it easy for the connecting plate 201 to rotate and drive the clamping plate 202 to rotate 90 degrees and separate from the surface of the fixed plate 1.

[0033] Refer to the instruction manual appendix Figure 1-5 The inner walls of the connecting plate 201 and the clamping plate 202 are provided with clamping grooves that match the sterile drape between them and the top of the fixing plate 1. The bottom of the fixing plate 1 is at a certain height from the transfer cart. The clamping grooves that match the sterile drape between the inner walls of the connecting plate 201 and the clamping plate 202 and the top of the fixing plate 1, and the bottom of the fixing plate 1 being at a certain height from the transfer cart, facilitate the cooperation between the connecting plate 201, the clamping plate 202 and the fixing plate 1 to clamp and fix the sterile drape, which can then be dropped onto the patient.

[0034] Refer to the instruction manual appendix Figure 1-5The quick-connect plate 303 has stepped notches at both ends of its outer wall, and the movable seat 302 has stepped grooves on its inner wall that match the stepped notches on the outer wall of the quick-connect plate 303. The surface of the stepped notches on the outer wall of the quick-connect plate 303 has slots that match the elastic pressure plate 306. The stepped notches at both ends of the outer wall of the quick-connect plate 303, the stepped grooves on the inner wall of the movable seat 302 that match the stepped notches on the outer wall of the quick-connect plate 303, and the slots that match the elastic pressure plate 306 on the surface of the stepped notches on the outer wall of the quick-connect plate 303 facilitate the interlocking of the movable seat 302 and the quick-connect plate 303, and the interlocking connection is achieved through the elastic pressure plate 306.

[0035] Refer to the instruction manual appendix Figure 1-5 The quick-connect plate 303 has a fixed groove inside that matches the electric slide table 304. The bottom ends of the electric slide table 304 and the fixed base 301 are both provided with sliding grooves that match the top slide rail of the transfer vehicle. The top of the pull rod 305 is mechanically fixed with a pull ring. The quick-connect plate 303 has a fixed groove inside that matches the electric slide table 304. The bottom ends of the electric slide table 304 and the fixed base 301 are both provided with sliding grooves that match the top slide rail of the transfer vehicle. This makes it easy for the electric slide table 304 to slide on the top slide rail of the transfer vehicle and drive the fixed base 301 to slide.

[0036] The working principle of this practical application is as follows:

[0037] Refer to the instruction manual appendix Figure 1-5 The movable seat 302 and the fixed base 301 are brought closer together by the pull rod 305, so that the movable seat 302 is sleeved on the outer wall of the quick-connect plate 303. The quick-connect plate 303 has stepped notches at both ends of its outer wall, and the movable seat 302 has stepped grooves that match the stepped notches on the outer wall of the quick-connect plate 303, so that the movable seat 302 and the quick-connect plate 303 are initially engaged. At the same time, the quick-connect plate 303 has slots that match the elastic pressure plate 306 on its outer wall stepped notch, so that the elastic pressure plate 306 on the inner wall of the movable seat 302 fits into the slots, thus completing the quick-installation and fixing of the movable seat 302 on the fixed base 301, thereby fixing the fixed plate 1 on the transfer cart, thus reducing the time for fixing the fixed plate 1 on the transfer cart. Meanwhile, the electric slide table 304 slides on the slide rail at the top of the transfer cart, driving the fixed base 301 to slide, which in turn drives the movable seat 302 to slide, thereby adjusting the fixed plate 1 to slide on the transfer cart.

[0038] Refer to the instruction manual appendix Figure 1-5The connecting plate 201 and the clamping plate 202 are rotatably connected to one end of the fixed plate 1 via a connecting shaft. This allows the connecting plate 201 to be opened, rotating to cause the clamping plate 202 to rotate 90 degrees and separate from the surface of the fixed plate 1. The sterile slip is then placed on the surface of the fixed plate 1, and the clamping plate 202 is then placed on top, causing the connecting plate 201 to rotate and thus the clamping plate 202 to rotate and fit against the surface of the fixed plate 1. Simultaneously, mounting grooves matching the button magnet 203 are provided on the inner walls of the connecting plate 201 and the clamping plate 202, as well as at the top of the fixed plate 1, facilitating the connection of the connecting plate 201... The button magnets 203 on the inner wall of the clamping plate 202 and the button magnets 203 on the fixing plate 1 attract and adhere to each other, so that the clamping plate 202 and the surface of the fixing plate 1 are tightly attached, thus completing the clamping and fixing of the sterile drape. At the same time, after the patient is transferred to the transfer cart, the fixing base 301 drives the fixing plate 1 to slide, causing the sterile drape to move and cover the patient's surface. Then, the clamping plate 202 is opened to release the clamping and fixing of the sterile drape, allowing the sterile drape to automatically fall off and remain on the patient, thus providing sterile protection for the patient. This can improve the work efficiency of medical staff and reduce their workload.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
