Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a treatment bed for PICC membrane replacement therapy. Background Technology

[0002] Peripherally inserted central catheter (PICC) placement involves inserting a catheter into a vein in the arm, directly reaching a large vein near the heart. This avoids direct contact between chemotherapy drugs and the arm veins. Furthermore, the rapid blood flow in large veins quickly dilutes the chemotherapy drugs, preventing irritation to the blood vessels. Therefore, it effectively protects the veins of the upper limb, reduces the incidence of phlebitis, alleviates patient pain, and improves the patient's quality of life. However, PICC membrane changes lack a standardized workbench or dedicated changing cart; the numerous materials required for membrane changes make conventional trays insufficient for treatment needs.

[0003] A mobile PICC membrane changing cart, disclosed in patent publication number CN215779476U, includes a workbench, a cart body, wheels, and a trash can, serving as a dedicated vehicle for PICC membrane changing. While the cart is mobile, it requires pushing each time it's used, resulting in low efficiency, especially in wards with limited space. In terms of space occupation, the cart is bulky and obstructs passageways, particularly in narrow wards. Moving the cart between different patients may pose a risk of cross-infection. Furthermore, traditional membrane changing procedures are generally performed in an open environment, making the cart susceptible to contamination from the surrounding environment. Utility Model Content

[0004] This invention provides a PICC membrane replacement treatment bed that is space-saving, infection-controlled, and easy to operate.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A PICC membrane replacement treatment bed includes a bed board, a clamping device held against the edge of the bed board, a sterile chamber body, and a connecting bracket connecting the clamping device and the sterile chamber body. The connecting bracket is a telescopic rod. The lower end of the connecting bracket is connected to the non-clamping end of the clamping device via a first rotary joint, and the upper end of the connecting bracket is connected to the bottom of the sterile chamber body via a second rotary joint. The sterile chamber body includes a frame-shaped base and a cover plate that cooperates with the frame-shaped base. The frame-shaped base has an arc-shaped groove in the middle of its outer side, and an inclined platform in the inner side of the arc-shaped groove. The upper surface of the inclined platform has an arc-shaped structure with both sides concave towards the center.

The fixed membrane replacement support is for one person's use, which is more hygienic and avoids cross-infection.

[0019] The designed aseptic chamber structure allows the frame-shaped base plate to be used as a membrane changing table, and the cover plate can be used to create a closed chamber that can be sterilized at any time, including the chamber itself and medical materials, to achieve a sterile environment as much as possible. In addition, the connecting bracket can be adjusted to a vertical position for easy membrane changing when in use, and when not in use, the connecting bracket can be turned into a horizontal bar and placed beside the bed, and the entire surface of the chamber can also be used as a small table.

The magnetic blocks and iron blocks are positioned at the overlapping portion of the side plates and the frame base when they are in contact. During membrane replacement, the first and second cover plates face outwards, and the open frame base serves as a membrane replacement table. After use, the first and second cover plates are closed, and the first and second side plates are placed over the frameless side of the frame base, creating a relatively enclosed space. The ultraviolet lamp is then turned on to disinfect the inner cavity and its contents. To facilitate opening and closing of the first and second cover plates, recessed handles can be provided on the cover panels.

[0027] The arc-shaped groove 22 and the inclined platform 23 are not aligned, and there is a gap between them. The frame-shaped base 20 is provided with a slide rail 4 on the inner side of the arc-shaped groove 22. The slide rail 4 is located at the bottom of the gap between the arc-shaped groove 22 and the inclined platform 23. A sliding plate 41 is slidably connected to the slide rail 4. The diameter of the sliding plate 41 is larger than the diameter of the arc-shaped groove 22. When the sliding plate 41 moves to the arc-shaped groove 22, it can cover the entire arc-shaped groove.

The button of the ultraviolet lamp 24 can be located on the outer wall of the sterile chamber body 2 for easy operation.

[0029] The inclined platform 23 is provided with a detachable medical silicone gauze pad 29, the surface of which is provided with an array of anti-slip bumps.

[0030] The sterile chamber body 2 is made of medical-grade polycarbonate material, and its inner surface is coated with a nano-silver antibacterial coating.

[0031] Figure 1 As shown, the clamping device 1 consists of an upper clamping plate 11 and a lower clamping plate 12. A clamping bolt 13 is installed on the top of the upper clamping plate. One end of the upper clamping plate 11 and the lower clamping plate 12 is installed on one side of the first rotary joint 30 via a fixing block 14. Rubber pads 15 are bonded to the facing surfaces of the upper clamping plate 11 and the lower clamping plate 12.

[0032] Figure 1 , Figure 3 As shown, the base plate 16 is connected to the outer side of the fixing block 14. The base plate 16 is provided with a rotating shaft 17. The first rotating joint 30 is a U-shaped frame structure whose bottom can be rotatably inserted into the rotating shaft. The two sides of the U-shaped frame structure are connected by a first joint shaft 31.

The four inner corners of the U-shaped frame facing the opening are provided with first limiting blocks 33. The first limiting blocks 33 can limit the bottom rod of the connecting bracket 3. The U-shaped frame is made of plastic. The bottom of the connecting bracket 3 can be adjusted laterally by 180° within the plastic U-shaped frame. Pushing the first limiting block to the left or right causes the U-shaped frame to expand slightly outward, and the connecting bracket rotates 90° to a horizontal position.

[0033] Figure 1 As shown, the sterile chamber body 2 is connected to the second rotating joint 50 at the bottom center near the clamping device 1. The first rotating joint 50 is a U-shaped frame structure, with the two sides of the U-shaped frame structure connected by a second joint shaft 51. The top of the connecting bracket 3 is provided with a second column ring 52 that fits onto the second joint shaft 51. Each of the four inner corners of the U-shaped frame facing the opening is provided with a second limiting block 53. The second limiting block 53 can limit the top rod of the connecting bracket 3. The U-shaped frame is made of plastic, and the bottom of the connecting bracket 3 can be adjusted laterally by 180° within the plastic U-shaped frame. Pushing the second limiting block 53 to the left or right causes the U-shaped frame to slightly expand outward, and the connecting bracket 3 rotates 90° to a horizontal position.

[0034] The side of the sterile compartment body 2 corresponding to the hinge position is also provided with a protrusion 8 that is flush with the top of its side. When the first cover and the second cover are opened and rotated 180°, they are placed on the protrusion 8 to form a horizontal panel that can be used to place items.

[0035] When not in use, the connecting bracket and the sterile chamber body are placed horizontally beside the bed. In use, rotate the connecting bracket upwards by 90° to make it vertical; simultaneously, rotate the sterile chamber body by 90° to keep its frame base level. Open the first and second covers, then place the patient's arm on the inclined table, with the wrist extending from the curved groove, to perform the membrane replacement procedure. After use, slide the slide plate 41 to the curved groove position to cover the area, close the cover, then rotate the connecting bracket downwards by 90° to make it horizontal, and rotate the sterile chamber body by 90° to keep it horizontal. Disinfection procedures can then be performed.
