A protective device to prevent hemodialysis tubing from falling off during hemodialysis care.

Abstract

This invention relates to the field of medical assistive devices and discloses a hemodialysis catheter anti-dislodgement protection device for hemodialysis care, including a dialysis machine. The dialysis machine has an alarm on its front and an anti-dislodgement structure on its front. The anti-dislodgement structure includes a bottom ring, and a telescopic tube is fixedly connected to one side of the bottom ring. The telescopic tube is retracted during use, and a connecting ring is provided on one side of the telescopic tube. The hemodialysis catheter anti-dislodgement protection device provided by this invention has an anti-dislodgement structure. This structure prevents the hemodialysis catheter from dislodging when the elderly move or pull it significantly, as the telescopic tube and the soft rubber rod work together. During significant movement or strong pulling, the thinner part of the soft rubber rod breaks, and the telescopic tube stretches outward a certain distance, offsetting the pulling force. This structure uses both plastic and flexible tubing, and the overall structure is simple and convenient, meeting the disposable standards for medical devices.

Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a hemodialysis tubing anti-dislodgement protection device for hemodialysis nursing. Background Technology

[0002] Patent application CN212651142U includes a fixing component with an anti-pull component extending through its center. A hemodialysis catheter is secured to the anti-pull component. The fixing component includes a fixing strap with a hook-and-loop fastener at one end and a snap fastener at the other end. The advantages are: the fixing component is secured to the patient's joints, bends in the hemodialysis catheter, or connections using the hook-and-loop fastener and snap fastener, making it easier to attach and detach. The anti-pull component, threaded onto the fixing component, secures the hemodialysis catheter. This method not only facilitates the fixing of the hemodialysis catheter during use but also its removal, offering greater practicality and versatility compared to traditional adhesive methods.

[0003] In the prior art, including the aforementioned patents, most disposable hemodialysis catheters lack effective protective structures at the dialysis machine location. The connection between the hemodialysis catheter and the dialysis machine mainly relies on plug-in or spiral connections. After plug-in hemodialysis catheters are connected, they may fall off due to manufacturing quality issues or subsequent human pulling (elderly people may unconsciously make large movements or pull the hemodialysis catheter due to resistance), causing harm to the patient. Spiral connections can firmly fix the hemodialysis catheter to the dialysis machine, but if the patient pulls or moves significantly, although the hemodialysis catheter will not fall off the machine, the connecting tube on the patient's body will be pulled. Because the fixed end is on the dialysis machine, the weakest point of the connection will be the tube opening on the human body. Summary of the Invention

[0004] The problem this invention aims to solve is that the connection between the dialysis machine and the hemodialysis tubing lacks a protective mechanism. The plug-in type fixation can fall off, while the spiral type fixation can cause the dialysis tubing to be pulled at the connection point with the patient's body, resulting in pain and discomfort.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a hemodialysis tube anti-dislodgement protection device for hemodialysis nursing, including a dialysis machine, an alarm provided on the front of the dialysis machine, an anti-dislodgement structure provided on the front of the dialysis machine, the anti-dislodgement structure including a bottom ring, a telescopic tube fixedly connected to one side of the bottom ring, the telescopic tube being in a retracted state during use, a connecting ring provided on one side of the telescopic tube, and a hemodialysis tube fixedly connected to one side of the connecting ring;

[0006] An arc-shaped groove is formed on the top of one side of the bottom ring. A movable ring and a fixed ring are respectively rotatably provided on the left and right sides of the bottom of the bottom ring. A limiting rod is fixedly provided on the top of one side of the movable ring. The limiting rod is adapted to the arc-shaped groove. The movable ring can move along the arc-shaped groove. Rubber rings are fixedly provided on the inner walls of both the movable ring and the fixed ring. A fixing screw passes through the top of the movable ring and the fixed ring. A lead wire is fixedly provided on one side of the top of the connecting ring. A plug is fixedly provided on one side of the lead wire. A pull ring is fixedly provided on the top of one side of the plug. A switch is provided on one side of the alarm. A battery box is provided at the bottom of the alarm. A spring is provided on the top of the inner wall of the battery box. A battery is provided at the bottom of the spring. A socket is formed on the bottom of one side of the battery box. The socket is adapted to the plug. The plug is used to separate the battery.

[0007] Preferably, the dialysis machine has a water rack on one side, a display screen on the top of the front of the dialysis machine, and a peristaltic pump on the bottom of the front of the dialysis machine.

[0008] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0009] (1) The connection between the dialysis machine and the hemodialysis tube is equipped with an anti-detachment structure. The anti-detachment structure can prevent the hemodialysis tube from falling off when the elderly move or pull it significantly. The soft rubber rod is used to limit the force and lock the telescopic tube to prevent the telescopic tube from being stretched during normal daily use and causing the protection mechanism to fail. When moving significantly or pulling strongly, the thinner part in the middle of the soft rubber rod will break, and the telescopic tube will stretch outward a certain distance to offset the pulling force, thus preventing the tube connected to the body from being pulled and causing discomfort to the patient. It can also prevent the hemodialysis tube from falling off the machine. This structure uses plastic structure and soft tube structure. The overall structure is simple and convenient and can meet the disposable use standard of medical devices. It does not need to be reused and cause infection. Moreover, the soft rubber rod and other objects are disposable and can be used in normal medical operation procedures.

[0010] (2) The bottom ring is equipped with a movable ring and a fixed ring, which can be used to connect dialysis machines with different interface sizes to increase the overall adaptability of the device. The movable ring and the fixed ring are tightened on the dialysis machine by rotating the fixing screw to prevent them from falling off. The rubber pads on the inner walls of the movable ring and the fixed ring can further increase the friction at the connection with the dialysis machine, making it more secure and stable. One side of the telescopic tube is equipped with a lead wire, and one end of the lead wire is equipped with a plug. In daily use, the plug can be inserted into the battery box to isolate the alarm. In case of an emergency, when the hemodialysis tube is stretched too much and a protective mechanism is formed, the plug will detach from the battery box. The battery and the power supply will touch each other to form a circuit cycle to trigger the alarm and make a sound, so that medical staff can discover such a situation first. This avoids the fact that the hemodialysis tube is stretched quickly and effectively in the noisy hospital environment, and makes it convenient for medical staff to come and check the condition of the hemodialysis tube and soothe the patient's emotions as soon as possible.

[0024] like Figures 1 to 10 As shown, the present invention provides a hemodialysis tube anti-dislodgement protection device for hemodialysis nursing, including a dialysis machine 7, an alarm 2 on the front of the dialysis machine 7, an anti-dislodgement structure 3 on the front of the dialysis machine 7, the anti-dislodgement structure 3 includes a bottom ring 304, a telescopic tube 303 fixedly connected to one side of the bottom ring 304, the telescopic tube 303 is in a retracted state when in use, a connecting ring 311 is provided on one side of the telescopic tube 303, and a hemodialysis tube 4 is fixedly connected to one side of the connecting ring 311.

[0025] An arc-shaped groove 312 is formed on the top of one side of the bottom ring 304. A movable ring 307 and a fixed ring 309 are respectively rotatably provided on the left and right sides of the bottom of the bottom ring 304. A limiting rod is fixedly provided on the top of one side of the movable ring 307. The limiting rod is adapted to the arc-shaped groove 312, and the movable ring 307 can move along the arc-shaped groove 312. Rubber rings 308 are fixedly provided on the inner walls of both the movable ring 307 and the fixed ring 309. A fixing screw 310 passes through the top of the movable ring 307 and the fixed ring 309. A lead wire 302 is fixedly provided on one side of the top of the connecting ring 311, and a plug 306 is fixedly provided on one side of the lead wire 302. A pull ring 301 is fixedly provided on the top of one side of the plug 306. A switch 8 is provided on one side of the alarm 2. A battery box 9 is provided at the bottom of the alarm 2. A spring 11 is provided at the top of the inner wall of the battery box 9. A battery 10 is provided at the bottom of the spring 11. A socket is provided at the bottom of one side of the battery box 9. The socket is adapted to the plug 306. The plug 306 is used to separate the battery 10.

[0026] A water rack 6 is provided on one side of the dialysis machine 7, a display screen 1 is provided on the top of the front of the dialysis machine 7, and a peristaltic pump 5 is provided on the bottom of the front of the dialysis machine 7.

[0027] The working principle and usage process of this invention: When using the device, medical personnel rotate and open the fixing screw 310. After opening, the movable ring 307 is rotated and opened with the connection point with the bottom ring 304 as the center. When the movable ring 307 is opened, the limiting rod on its back will move along the arc groove 312. After opening the movable ring 307, it can be placed on the connection point of the dialysis machine 7. After placing it, close the movable ring 307 and tighten the fixing screw 310. The movable ring 307, together with the fixing ring 309, can firmly fix the connection point of the dialysis machine 7. The rubber ring 308 provided on the inner wall of the movable ring 307 and the fixing ring 309 can increase the friction with the surface of the connection point of the dialysis machine 7, making it more secure. After the hemodialysis tube 4 is connected to the dialysis machine 7, insert the insert 306 on one side of the connecting ring 311 into the battery box 9. The insert 306 will separate the battery 10 in the battery box 9, making its circuit de-energized. Then turn on the switch 8 on the alarm 2. Yes, then connect the hemodialysis tubing 4 to the dialysis tubing in the patient's body as normal, and use the dialysis machine 7 for treatment as usual. When the patient moves and pulls the hemodialysis tubing 4 significantly, if the pulling amplitude and force exceed the limit that the soft rubber rod 305 can withstand, the soft rubber rod 305 will break. At this time, as the force continues, the originally constricted telescopic tube 303 will extend outward to offset the pulling force of the patient, without causing pain or discomfort to the patient or affecting the normal operation of the machine. While the telescopic tube 303 extends outward, the insert 306 will detach from the battery box 9 through the pull of the lead wire 302. The batteries 10 in the battery box 9 will then contact each other to form a circuit, causing the alarm 2 to sound, so that medical staff can discover the problem immediately, come to comfort the patient and check whether the hemodialysis tubing 4 is connected properly. The hemodialysis tubing 4 and the anti-detachment structure 3 are both disposable medical consumables. After use, they can be replaced with new ones for continued use.
