Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a single roll of padding for an examination bed and its installation structure. Background Technology
[0002] During medical examinations, disposable sanitary sheets are typically used to prevent cross-infection and contamination on the examination bed. Currently, a common type of examination bed sheet roll on the market is formed by winding multiple layers of paper or non-woven fabric onto a core. One end of the core is fixed to one side of the examination bed, and the other end is connected to the other side of the examination bed via a cutting device. In use, the sheet is pulled out from the core, placed on the examination bed, and then cut using the cutting device to create a sheet suitable for the size of the examination bed.
[0003] Existing invention patent CN219878570U discloses a diaper roll for examination beds and its installation structure, which includes a self-adhesive roll and a diaper roll formed by a diaper wound on the self-adhesive roll; the self-adhesive roll includes a core, an adhesive layer is circumferentially disposed on the outer layer of the core, and a release film layer is circumferentially disposed on the side of the adhesive layer away from the core, the circumference of the release film layer being greater than that of the adhesive layer; at least one side of the diaper has an edge-sealing adhesive layer on both sides in the width direction along the length direction; it solves the problem of how to quickly and safely replace and recycle disposable diapers during hospital examinations, which can improve work efficiency, avoid cross-infection, and improve the patient's medical experience.
[0004] Existing drape rolls are used to collect used drapes using a take-up roller, while unused drapes are laid on the examination bed. However, the installation structure of existing drape rolls makes it difficult to achieve an automated drape laying and collection process. In addition, since the patient's skin health status is unknown, there is a risk of accidental contact infection during collection. Furthermore, the drapes may become misaligned or wrinkled during the patient's movement on and off the examination bed, potentially leading to direct contact with the bed and thus posing a risk of cross-infection.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] 1. This invention, through the setting of a laying structure, can complete the automatic laying and rolling process of the diaper on the examination bed. When the diaper layer is recycled, it can avoid the side of the diaper layer that the patient directly touches from coming into contact with staff or other patients, reducing the risk of contact infection. When laying or rolling the diaper layer, it can disinfect the area where the patient gets on and off the bed, improving the cleanliness and hygiene of the bed board, thereby effectively preventing cross-infection and contamination.
[0019] 2. The single-time recovery length of the roll-up cylinder in this invention is slightly longer than the single-use length of the roll-up cylinder. This is because when patients use the examination bed later, they may come into contact with the unused roll-up cylinder core. Therefore, the excess unused roll-up portion can more effectively prevent cross-infection between patients. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figures 1 to 9 The present invention provides a technical solution: a test bed pad roll, including a pad roll 3, the pad roll 3 including a core 301, the outer circumferential of the core 301 is provided with an adhesive layer, and a pad layer 302 is wound around the outer side of the adhesive layer.
[0032] A self-adhesive layer 303 is provided at the end of the pad layer 302 away from the core 301. The self-adhesive layer 303 is located on the upper surface of the pad layer 302, and release paper is adhered to the self-adhesive layer 303.
[0033] Both ends of the core 301 are provided with column grooves 304. A take-up drum 4 is provided on one side of the core 301. The take-up drum 4 is arranged parallel to the core 301. Both ends of the take-up drum 4 are provided with two sets of hexagonal grooves 401. The take-up drum 4 is provided with an area for fixing the self-adhesive layer 303.
[0034] like Figure 1 and Figure 9 As shown, when the pad cylinder 3 is used on the examination bed, the pad cylinder 3 is stably positioned above the examination bed by the column grooves 304 provided at both ends of the cylinder core 301. At the same time, by driving the cylinder core 301 to move in the horizontal direction, the cylinder core 301 can rotate freely in the vertical direction and release part of the pad layer 302. Meanwhile, one end of the pad layer 302 is adhered to the take-up drum 4 by the self-adhesive layer 303. The take-up drum 4 is set on one side of the examination bed by the hexagonal groove 401, and the position of the take-up drum 4 is fixed. Therefore, the release length of the pad layer 302 is related to the horizontal distance of the cylinder core 301.
[0035] Meanwhile, when the used pad 302 needs to be recycled after a single patient's examination, the drive core 301 moves toward the take-up drum 4. At this time, the take-up drum 4 rotates freely in the vertical direction and recycles the used pad 302. It should be noted that the upper surface of the pad 302 ends at the surface of the take-up drum 4, that is, the take-up drum 4 recycles the side of the pad 302 that was in contact with the patient. Therefore, the used pad 302 is on the take-up drum 4 with its back side facing outward. The back side of the pad 302 is the side that is not in direct contact with the patient. Therefore, when recycling the pad 302, the side of the pad 302 that was in direct contact with the patient can be prevented from coming into contact with staff or other patients, reducing the risk of contact infection and thus preventing cross-infection.
[0036] It should also be noted that the release length of the single layer 302 is related to the horizontal distance of the core 301, and can be adjusted according to the size of different examination beds to avoid waste and discomfort of the single layer 302. Furthermore, as the length of the single layer 302 recovered by the winding drum 4 increases, the thickness of the single layer 302 wound on its surface also increases. Therefore, in actual use, the single recovery length of the single layer 302 by the winding drum 4 will be slightly longer than the single use length of the single layer 302. This is because when patients use the examination bed later, they may come into contact with the unused single layer 302 on the core 301. Therefore, the excessive recovery of the single layer 302 can more effectively prevent cross-infection between patients.
[0037] An installation structure for a test bed mattress roll includes a bed body 1, which includes a bed board and support legs, and a mattress layer 302 laying structure is provided on the bed body 1.
[0038] The laying structure includes two sets of side uprights 2, which are fixedly connected to one end of the bed board. The two sets of side uprights 2 are respectively provided with guide posts 6 and directional posts 25. The two sets of side uprights 2 are provided with inverted V grooves 5 for the guide posts 6 and directional posts 25 to slide horizontally. One set of side uprights 2 is provided with a swing assembly for driving the guide posts 6 to move horizontally. The side of the guide post 6 facing the directional post 25 is fixedly connected with a left snap-fit post 23. The directional post 25 is provided with a right snap-fit post 24. A space for placing the core 301 is formed between the left snap-fit post 23 and the right snap-fit post 24. The directional post 25 is provided with a plug-in assembly for adjusting the horizontal longitudinal position of the right snap-fit post 24.
[0039] like Figure 1 , Figure 3 , Figure 5 and Figure 8 As shown, the left locking post 23 and the right locking post 24 are respectively inserted into the column grooves 304 at both ends of the core 301. The left locking post 23 is fixedly connected to the guide post 6, and the right locking post 24 is set on the directional post 25. By driving the guide post 6 to slide on the inverted V groove 5, the core 301 moves horizontally. When the core 301 moves horizontally, since one end of the pad 302 is attached to the take-up drum 4, the core 301 moves horizontally and rotates vertically at the same time, thereby releasing the pad 302. When the core 301 is at the end of its stroke away from the take-up drum 4, the process of laying the pad 302 on the bed board is completed.
[0040] In one preferred embodiment, a left-side locking block 17 and a right-side locking block 18 are provided on one side of the bed board, which are arranged opposite to each other. The left-side locking block 17 and the right-side locking block 18 are respectively inserted into a set of hexagonal slots 401, and a space for placing the winding drum 4 is formed between the left-side locking block 17 and the right-side locking block 18. A winding assembly for driving the left-side locking block 17 to rotate vertically is provided on one set of side uprights 2, and an anti-pulling assembly for restricting the rotation direction of the right-side locking block 18 is provided on another set of side uprights 2.
[0041] like Figure 5 and Figure 7 As shown, when installing the take-up drum 4, the left locking block 17 and the right locking block 18 are respectively inserted into the hexagonal slots 401 at both ends of the take-up drum 4. By driving the left locking block 17 to rotate, the take-up drum 4 is driven to rotate. When the drum core 301 moves toward the take-up drum 4, the take-up drum 4 rotates in the vertical direction and winds up the used pad layer 302, thereby reducing the workload of the workers. At the same time, it prevents personnel from coming into contact with the used pad layer 302 and avoids contact infection.
[0042] Furthermore, the lateral swing assembly includes a driven plate 10 that swings back and forth in an arc-shaped trajectory in the vertical direction. The side plate 2 is provided with a circular groove for the driven plate 10 to slide. A main connecting rod 9 is fixedly connected to the driven plate 10. A driven swing rod 7 is provided on one side of the main connecting rod 9. A guide post 6 is fixedly connected to one end of the driven swing rod 7 facing the inverted V groove 5. A relief post 8 is fixedly connected to the main connecting rod 9. A through groove is opened on the driven swing rod 7 for the relief post 8 to slide. A disinfection component for spraying disinfectant is provided on the driven swing rod 7.
[0043] like Figure 1 , Figure 5 and Figure 6 As shown, the driven disk 10 reciprocates in the vertical direction along an arc trajectory, thereby driving the main connecting rod 9 and the relief column 8 mounted on it to swing synchronously. The relief column 8 slides in contact with the through groove opened on the driven rocker arm 7. Therefore, when the main connecting rod 9 swings, it can drive the driven rocker arm 7 to swing in the vertical direction. The guide column 6 is fixedly connected to the driven rocker arm 7. The guide column 6 moves along the opening trajectory of the inverted V groove 5. Therefore, when the driven rocker arm 7 swings, its vertical height changes synchronously.
[0044] Based on the embodiment of the horizontal swing assembly, the disinfection assembly includes a sealing cylinder 30 fixedly connected to the support leg. A piston plate 29 is slidably contacted on the inner wall of the sealing cylinder 30. A piston rod 28 is fixedly connected to the piston plate 29. The piston rod 28 slides through the sealing cylinder 30. An adjusting rod 32 is provided at the end of the piston rod 28 away from the piston plate 29. The two ends of the adjusting rod 32 are respectively fixedly rotated on the piston rod 28 and the swing rod 7. A water outlet pipe is provided on the sealing cylinder 30. A horizontal pipe 31 is fixedly connected at the end of the side plate 2 away from the winding drum 4. The two ends of the water outlet pipe are respectively fixedly connected to the sealing cylinder 30 and the horizontal pipe 31.
[0045] like Figure 1 and Figure 6 As shown, when the swing arm 7 swings vertically, it can drive the adjusting rod 32 to deflect. At the same time, when the adjusting rod 32 deflects, its vertical height changes, thus driving the piston rod 28 and piston plate 29 to move inside the sealing cylinder 30. Through the movement of the piston plate 29, the disinfectant in the sealing cylinder 30 is sprayed onto the bed board through the transverse pipe 31. The sealing cylinder 30 is fixedly connected to the disinfection box through the water inlet pipe, and one-way valves are fixedly connected to both the water inlet pipe and the water outlet pipe. By setting two sets of one-way valves, the disinfectant can only flow from the disinfection box through the sealing cylinder 30 and into the transverse pipe 31.
[0046] It should be noted that since the winding drum 4 is located on one side of the bed board, in order to avoid the patient coming into contact with the single layer 302 already used on the winding drum 4 during use, the patient should get on and off the bed board from the side away from the winding drum 4 when using the bed 1. By setting up a disinfection component, the area where the patient gets on and off the bed board can be disinfected, improving the cleanliness and hygiene of the bed board, preventing the patient from being infected or spreading diseases when getting on and off the bed, ensuring the health and safety of patients and medical staff, and avoiding contact infection.
[0047] Based on the disinfection component embodiment, the plug-in component includes an end plate 27 fixedly connected to the right snap-fit post 24, the right snap-fit post 24 slidingly passing through the directional post 25, and a spring 26 sleeved on the right snap-fit post 24, with the two ends of the spring 26 fixedly connected to the end plate 27 and the directional post 25 respectively.
[0048] like Figure 2 and Figure 8 As shown, when installing the single cylinder 3, pull the end plate 27 to stretch the spring 26 and simultaneously retract the right-side locking post 24 into the directional post 25. At this time, insert the left-side locking post 23 into the groove 304 at one end of the cylinder core 301, and align the groove 304 at the other end of the cylinder core 301 with the right-side locking post 24. Then, release the end plate 27, and the spring 26 will return to its original deformation and drive the right-side locking post 24 to be inserted into the groove 304. By setting the insertion assembly, the stability of the cylinder core 301 is ensured, making it convenient for users to install or replace the single cylinder 3, and ensuring that the cylinder core 301 can rotate freely when moving in the horizontal direction.
[0049] Based on the plug-in assembly embodiment, the winding assembly includes a first gear 14 driven by a motor to rotate vertically. The first gear 14 meshes with a second gear 13. A drive disc 12 is provided on one side of the second gear 13. The drive disc 12 is coaxially fixed on the second gear 13. The second gear 13 rotates on a fixed axis on the side plate 2. A driven link 11 is provided on one side of the drive disc 12. The two ends of the driven link 11 rotate on the drive disc 12 and the driven disc 10 respectively. An incomplete gear 15 is coaxially fixed to the first gear 14. A third gear 16 is provided on one side of the incomplete gear 15. The third gear 16 meshes with the incomplete gear 15. The third gear 16 rotates on a fixed axis on the side plate 2. The side of the third gear 16 away from the side plate 2 is fixedly connected to the left side locking block 17.
[0050] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the motor drives the first gear 14 and the coaxial incomplete gear 15 to rotate in the vertical direction. During the rotation of the first gear 14, it drives the second gear 13, which meshes with it, to rotate synchronously. The second gear 13 is coaxially fixed with the driving disk 12, which in turn drives the driving disk 12 to rotate in the vertical direction. During the rotation of the driving disk 12, it drives the driven connecting rod 11 to deflect, which in turn drives the driven disk 10 to rotate in the vertical direction. It should be noted that the diameter of the driving disk 12 is smaller than the diameter of the driven disk 10. Therefore, when the driving disk 12 rotates one revolution, the rotation trajectory of the driven disk 10 is fan-shaped, which in turn drives the main connecting rod 9 on the driven disk 10 to swing back and forth in an arc trajectory.
[0051] At the same time, when the pad single tube 3 moves toward the take-up drum 4, the incomplete gear 15 gradually meshes with the third gear 16 and drives the third gear 16 to rotate, thereby driving the left locking block 17 on the third gear 16 to rotate synchronously. The left locking block 17 and the right locking block 18 are inserted into the hexagonal slots 401 at both ends of the take-up drum 4, so that the rotation of the left locking block 17 drives the take-up drum 4 to rotate in the vertical direction, thereby enabling the use of the pad single layer 302 to be wound up.
[0052] Based on the winding assembly embodiment, the anti-pull assembly includes a receiving shell 19 disposed on the side plate 2. A telescopic rod 22 is provided on the side of the receiving shell 19 facing the side plate 2. The fixed end of the telescopic rod 22 is fixedly connected to the side plate 2, and the movable end of the telescopic rod 22 is fixedly connected to the receiving shell 19. A ratchet 20 is fixedly rotatable on the inner wall of the receiving shell 19. A blocking block 21 is provided on one side of the ratchet 20. The blocking block 21 is fixedly rotatable on the receiving shell 19. The side of the ratchet 20 away from the side plate 2 is fixedly connected to the right-side locking block 18.
[0053] like Figure 1 , Figure 2 and Figure 7 As shown, when the pad drum 3 moves horizontally away from the take-up drum 4, the incomplete gear 15 does not mesh with the third gear 16. In order to prevent the take-up drum 4 from rotating and releasing the used pad layer 302, a ratchet 20 is provided on the right-side locking block 18, and a stop block 21 is provided on one side of the ratchet 20. The rotation direction of the ratchet 20 is restricted by the stop block 21, thereby preventing the take-up drum 4 from releasing the pad layer 302. A torsion spring is provided between the stop block 21 and the housing 19 to drive the stop block 21 back to its initial position. The stop block 21 is in close contact with the surface of the ratchet 20 in the initial state. This torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure.
[0054] Meanwhile, when installing the take-up drum 4, by adjusting the overall length of the telescopic rod 22 and the horizontal position of the right-side locking block 18, the left-side locking block 17 is first inserted into the hexagonal slot 401 on one side of the take-up drum 4, and the right-side locking block 18 is aligned with another set of hexagonal slots 401. The telescopic rod 22 is then adjusted so that the right-side locking block 18 is inserted into the hexagonal slot 401. The anti-pull component facilitates the installation and disassembly of the take-up drum 4, and at the same time restricts the rotation of the take-up drum 4, preventing the single layer 302 of the pad from being pulled out after use.
[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
