Description

Technical Field

[0001] This utility model belongs to the technical field of nursing kits for hemodialysis, specifically a nursing kit for deep vein catheterization in hemodialysis. Background Technology

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. During hemodialysis, we first disinfect and prepare the patient's vascular access using a hemodialysis care kit. Then, we connect the pre-charged dialyzer and tubing to the patient's vascular access to establish extracorporeal circulation and begin hemodialysis treatment. When not in use, the central venous catheter used for hemodialysis is usually placed in the care kit.

[0003] However, in existing technologies, deep vein catheters are usually placed directly in the corresponding placement slot in the nursing kit, which is not secure enough. During transportation or movement, the deep vein catheter is prone to falling out of the placement slot, resulting in damage to the deep vein catheter. Summary of the Invention

[0004] The purpose of this invention is to provide a deep vein catheterization care kit for hemodialysis, which can firmly fix the deep vein catheter inside the care kit and prevent it from falling out of the placement slot and being damaged during transportation or movement.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A deep vein catheterization care kit for hemodialysis is provided, comprising a shell, a top cover mounted on the top of the shell, a support plate fixedly connected to the lower inner wall of the top cover, a bidirectional lead screw movably connected inside the support plate, knobs fixedly connected to both ends of the bidirectional lead screw, and movable plates threadedly connected to both ends of the outer wall of the bidirectional lead screw. Two rotating grooves are formed at the bottom of the movable plates, and connecting rods are movably connected to the inner walls of the rotating grooves. A pressure plate is provided inside the bottom of the shell, and multiple U-shaped plates are fixedly connected to the top of the pressure plate. The bottoms of multiple connecting rods are movably connected to the inner walls of the multiple U-shaped plates, and multiple pressure springs are fixedly connected to the top of the pressure plate. The tops of the multiple pressure springs are fixedly connected to the top of the bottom inner wall of the top cover.

[0006] Optionally, each of the two movable plates has a through hole, and there are two through holes in each of them. The bottom inner wall of the top cover is fixedly connected with a limit rod, and there are two limit rods in total. Both limit rods pass through the two movable plates.

[0007] Optionally, a sealing gasket is fixedly connected to the top of the housing, and the sealing gasket is located between the housing and the top cover.

[0008] Optionally, the outer wall of the housing has two connecting grooves, the interior of the housing has two slots, the two connecting grooves are respectively connected to the two slots, the outer wall of the housing has multiple spring grooves, a locking plate is installed inside each of the two connecting grooves, a connecting plate is fixedly connected to one end of the locking plate, a locking spring is fixedly connected to the inner wall of the connecting plate, and the number of locking springs is two, and a pull plate is fixedly connected to the outer wall of the connecting plate.

[0009] Optionally, the bottom of the top cover is fixedly connected with two insert plates, the positions of the two insert plates correspond to the positions of the two slots respectively, and the interior of each of the two insert plates is provided with a locking groove.

[0010] Optionally, the other end of the locking spring is fixedly connected to the inner wall of the spring groove, and one end of the two locking plates located inside the slot is an inclined surface.

[0011] Optionally, the top of the housing is provided with a positioning groove, and there are multiple positioning grooves. The bottom of the top cover is fixedly connected with a positioning rod, and there are multiple positioning rods. The positions of the multiple positioning rods correspond to the positions of the multiple positioning grooves.

[0012] Optionally, handle grooves are provided on both outer walls of the housing, and handles are movably connected inside the handle grooves. Multiple placement grooves are provided on the bottom of the inner wall of the housing. Rubber pads are fixedly connected to the bottom of the inner wall of each of the multiple placement grooves. Multiple support feet are fixedly connected to the bottom of the housing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, after the top cover is installed on the top of the housing, turning the knob on one side drives the bidirectional lead screw to rotate, causing the two moving plates to move in opposite directions. One end of the connecting rod connected to it moves accordingly, while the other end of the connecting rod pushes the U-shaped plate and the pressure plate down until the bottom of the pressure plate contacts the deep vein catheter inside the housing. This ensures that the deep vein catheter in the housing is always located inside the corresponding placement slot. At this time, multiple pressure plate springs are in a stretched state, and the pressure plate only limits the deep vein catheter in the housing, without completely pressing it. This prevents the deep vein catheter in the housing from falling out of the placement slot during transportation or movement, thus protecting the deep vein catheter inside. When using the deep vein catheter, simply separate the top cover from the top of the housing.

[0015] 2. When installing the top cover, insert the two insert plates connected to the bottom of the top cover into the two slots opened in the housing. During the process of the insert plates entering the slots, the inclined end of the locking plate is squeezed by the insert plates, which drives the connecting plate to move outward of the housing. At this time, the locking spring is in a stretched state. After the insert plates are fully inserted into the slots, the multiple locking springs rebound, causing the locking plate to return to the locking groove opened in the insert plates, thereby making the top cover and the housing tightly connected. After the top cover is fixed on the housing, the handle can be removed from the handle groove for easy carrying of this utility model. Attached Figure Description

[0029] Reference Figure 1-7The present invention will now describe a deep vein catheterization care kit for hemodialysis provided in an embodiment of the present invention. A deep vein catheterization care kit for hemodialysis includes a shell 1. A top cover 2 is installed on the top of the shell 1. A support plate 3 is fixedly connected to the inner wall of the lower end of the top cover 2. A bidirectional screw 4 is movably connected inside the support plate 3. A knob 5 is fixedly connected to both ends of the bidirectional screw 4. A movable plate 6 is threaded to both ends of the outer wall of the bidirectional screw 4. The bottom of the movable plate 6 has a rotating groove 7, and there are two rotating grooves 7. A connecting rod 8 is movably connected to the inner wall of the rotating groove 7. A pressure plate 9 is provided inside the bottom end of the shell 1. A U-shaped plate 10 is fixedly connected to the top of the pressure plate 9, and there are multiple U-shaped plates 10. The bottoms of multiple connecting rods 8 are movably connected to the inner walls of multiple U-shaped plates 10. A pressure plate spring 11 is fixedly connected to the top of the pressure plate 9, and there are multiple pressure plate springs 11. The tops of multiple pressure plate springs 11 are fixedly connected to the top of the inner wall of the bottom end of the top cover 2. After the top cover 2 is installed on the top of the shell 1, the knob 5 on any side can be turned to bring... The rotating bidirectional lead screw 4 causes the two moving plates 6 to move in opposite directions. One end of the connecting rod 8 connected to it moves accordingly, while the other end of the connecting rod 8 pushes the U-shaped plate 10 and the pressure plate 9 downward until the bottom of the pressure plate 9 contacts the deep vein catheter inside the housing 1. This ensures that the deep vein catheter in the housing 1 is always located inside the corresponding placement slot. At this time, multiple pressure plate springs 11 are in a stretched state, and the pressure plate 9 only limits the deep vein catheter in the housing 1 without fully compressing it. This prevents the deep vein catheter in the housing 1 from falling out of the placement slot during transportation or movement, thus protecting the deep vein catheter inside. When using the deep vein catheter, the top cover 2 can be separated from the top of the housing 1. The interior of each of the two moving plates 6 is provided with through holes 12, and there are two through holes 12 in each case. The bottom inner wall of the top cover 2 is fixedly connected with two limiting rods 13, and both limiting rods 13 pass through the two moving plates 6.

[0030] In another embodiment of this utility model, please refer to Figure 2 A sealing gasket 14 is fixedly connected to the top of the housing 1. The sealing gasket 14 is located between the housing 1 and the top cover 2. After the top cover 2 is tightly connected to the housing 1, the sealing gasket 14 can play a sealing role to prevent dust from entering the interior of the housing 1.

[0031] In another embodiment of this utility model, please refer to Figures 3 to 6The outer wall of the housing 1 has two connecting grooves 15. The interior of the housing 1 has two slots 16.

Correspondingly, each of the two insert plates 22 has a locking groove 23 inside. When installing the top cover 2, the two insert plates 22 connected to the bottom of the top cover 2 are respectively inserted into the two slots 16 opened in the housing 1. During the process of the insert plate 22 entering the slot 16, the inclined end of the locking plate 18 is squeezed by the insert plate 22, which drives the connecting plate 19 to move outward of the housing 1. At this time, the locking spring 20 is in a stretched state. After the insert plate 22 is fully inserted into the slot 16, the multiple locking springs 20 rebound, so that the locking plate 18 returns to the locking groove 23 opened in the insert plate 22, thereby making the top cover 2 tightly connected to the housing 1.
