Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, and specifically relates to a hemodialysis tube anti-detachment protection device for hemodialysis care. Background Art

[0002] In the patent application with the publication number CN212651142U, it includes a fixing component, and an anti-pulling component is disposed through the middle of the fixing component, and a hemodialysis catheter is clamped on the anti-pulling component; the fixing component includes a fixing band, a hook-and-loop fastener is disposed on the band body at one end of the fixing band, and a plush fastener is disposed on the band body at the other end of the fixing band. The advantages are as follows: The fixing component is fixed at an easily detachable place such as the joint of the patient, the bending part of the hemodialysis catheter or the connection part of the hemodialysis catheter through the hook-and-loop fastener and the plush fastener. The anti-pulling component is threadedly disposed on the fixing component, and the hemodialysis catheter is clamped on the anti-pulling component. In this way, not only is it convenient to fix the hemodialysis catheter during use, but also it is convenient to disassemble the hemodialysis catheter. Compared with the traditional adhesive method, the practicability and versatility are stronger.

[0003] In the prior art including the above patents, most disposable hemodialysis tubes lack an effective protection structure at the position with the dialysis machine. The connection between the hemodialysis tube and the dialysis machine mainly relies on plugging or screw connection. After the plug-in type hemodialysis tube is connected, due to manufacturing quality or later manual pulling (there will be large-amplitude movements by the elderly unconsciously or pulling of the hemodialysis tube due to resistance), the hemodialysis tube may fall off, causing harm to the patient. The screw connection can firmly fix the hemodialysis tube on the dialysis machine. However, when the patient pulls or moves greatly, although the hemodialysis tube will not fall off the instrument, the connecting tube on the patient's body will be affected. Since the fixed end is at a relatively weak position on the dialysis machine, the connecting tube at the body connection of the patient will be in a vulnerable position. Summary of the Invention

[0004] The problem to be solved by the present invention is that there is a lack of a protection mechanism at the connection between the dialysis machine and the hemodialysis tube. The plug-in type fixation may fall off, and the screw type fixation may cause pulling at the connection between the dialysis tube on the patient's body and the body, resulting in pain and discomfort to the patient.

[0005] To solve the above technical problems, the technical solution of the present invention is: A hemodialysis tube anti-detachment protection device for hemodialysis care includes a dialysis machine. An alarm is provided on the front of the dialysis machine, and an anti-detachment structure is provided on the front of the dialysis machine. The anti-detachment structure includes a bottom ring. One side of the bottom ring is fixedly communicated with a telescopic tube, and the telescopic tube is in a contracted state during use. A connection ring is provided on one side of the telescopic tube, and a hemodialysis tube is fixedly communicated on one side of the connection ring.

[0006] Preferably, an arc-shaped groove is opened at the top of one side of the bottom ring, and a movable ring and a fixed ring are respectively rotatably provided on the left and right sides of the bottom of the bottom ring.

[0007] Preferably, a limiting rod is fixedly provided on the top of one side of the movable ring, the limiting rod is matched with the arc groove, and the movable ring can move along the slide groove.

[0008] Preferably, rubber rings are fixedly provided on the inner walls of the movable ring and the fixed ring, and fixing screws penetrate the tops of the movable ring and the fixed ring.

[0009] Preferably, a lead wire is fixedly provided on one side of the top of the connecting ring, an insert is fixedly provided on one side of the lead wire, and a pull ring is fixedly provided on the top of one side of the insert.

[0010] Preferably, 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 at the top of the inner wall of the battery box, and a battery is provided at the bottom of the spring.

[0011] Preferably, a plug hole is provided at the bottom of one side of the battery box, the plug hole is adapted to be matched with a plug-in piece, and the plug-in piece is used to separate the battery.

[0012] Preferably, a water hanging rack is provided on one side of the dialysis machine, a display screen is provided on the top of the front of the dialysis machine, and a peristaltic pump is provided on the bottom of the front of the dialysis machine.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) An anti-slip structure is provided at the connection between the dialysis machine and the hemodialysis tube. The anti-slip structure can prevent the hemodialysis tube from falling off when the elderly move or pull the hemodialysis tube drastically through the cooperation between the telescopic tube and the soft rubber rod. 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 the patient moves drastically or pulls strongly, the thinner part in the middle of the soft rubber rod will break, and the telescopic tube will be stretched outward for a distance, which will offset the pulling force, thus preventing the tube connected to the human body from being pulled and causing discomfort to the patient. It can also prevent the hemodialysis tube from falling off the machine. This structure adopts plastic structure and hose structure. The overall structure is simple and convenient, which can meet the disposable standards of medical devices and does not need to be repeatedly used to cause infection. In addition, objects such as the soft rubber rod are disposable and can be used in normal medical operations. (2) An activity ring and a fixed ring are provided on the bottom ring, which can facilitate the connection of dialysis machines with different interface sizes and increase the overall adaptability of the device. The activity ring and the fixed ring are tightened on the dialysis machine by rotating the fixing screws to prevent dropping. The rubber pads on the inner walls of the activity ring and the fixed ring can further increase the friction at the connection with the dialysis machine, making it more firm and stable. A lead wire is provided on one side of the telescopic tube, and a plug is provided at one end of the lead wire. During daily use, the plug can be inserted into the battery box to cut off the alarm. In case of an emergency, when the blood dialysis tube is subjected to a large pull and forms a protection mechanism, the plug disengages from the battery box, and the battery and the power source come into contact with each other to form a circuit loop, triggering the alarm to sound, enabling medical staff to discover such a situation first and avoiding the noisy hospital environment from preventing the stretching of the blood dialysis tube from being quickly and effectively detected, facilitating medical staff to come and check the condition of the blood dialysis tube and comfort the patient's emotions in a timely manner.

[0022] A lead wire 302 is fixedly provided on one side of the top of the connecting ring 311. A plug piece 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 piece 306.

[0023] One side of the alarm 2 is provided with a switch 8, and the bottom of the alarm 2 is provided with a battery box 9. The top of the inner wall of the battery box 9 is provided with a spring 11, and the bottom of the spring 11 is provided with a battery 10.

[0024] A jack is opened at the bottom of one side of the battery box 9, and the jack is adapted to a tab 306, and the tab 306 is used to separate the battery 10.

[0025] One side of the dialysis machine 7 is provided with an IV pole 6, the top of the front of the dialysis machine 7 is provided with a display screen 1, and the bottom of the front of the dialysis machine 7 is provided with a peristaltic pump 5.

[0026] The working principle and usage process of the present invention: When in use, medical staff rotate and open the fixing screw 310. After opening, the movable ring 307 is rotated and opened with the rotation 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-shaped groove 312. After opening the movable ring 307, it can be sleeved on the connection part of the dialysis machine 7. After sleeving, close the movable ring 307 and tighten the fixing screw 310. The movable ring 307 and the fixed ring 309 can firmly fix the connection part of the dialysis machine 7. The rubber ring 308 provided on the inner walls of the movable ring 307 and the fixed ring 309 can increase the friction force with the surface of the connection part of the dialysis machine 7 to make it more firm. After the blood dialysis tube 4 is connected to the dialysis machine 7, the tab 306 on one side of the connection ring 311 is inserted into the battery box 9.

Then normally connect the blood dialysis tube 4 to the dialysis tube in the patient's body and normally use the dialysis machine 7 for treatment. When the patient moves and pulls the blood dialysis tube 4 greatly, when the pulling amplitude and force are greater than the limit that the soft rubber rod 305 can bear, the soft rubber rod 305 will break. At this time, with the continuous application of force, the originally contracted telescopic tube 303 will extend outwards to offset the pulling force of the patient, without causing pain and discomfort to the patient and without affecting the normal operation of the machine. At the same time when the telescopic tube 303 extends outwards, the tab 306 will be detached from the battery box 9 under the traction of the lead wire 302, and the batteries 10 in the battery box 9 will come into contact with each other to form a circuit to make the alarm 2 sound, so that medical staff can discover the problem in the first time, come to comfort the patient's emotions and check whether the connection of the blood dialysis tube 4 is normal. The blood dialysis tube 4 and the anti-disconnection structure 3 are both disposable medical consumables. After use, replace with a new one and continue to use.
