Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a fixing device for a dialysis tube, belonging to the technical field of hemodialysis. Background Art

[0002] Hemodialysis is the most effective treatment for patients with uremia. Most patients undergo hemodialysis through long-term intravenous cannulation. During hemodialysis, one dialysis tube extracts the patient's pathogen-free blood and transports it to the hemodialysis machine for filtration, detoxification, and cleansing. Another dialysis tube returns the processed blood from the machine and re-injects it into the patient's body. This is the general process of hemodialysis. Dialysis tube fixtures play an important role in the medical field. They are designed to ensure the stability and safety of the dialysis tube on the patient.

[0003] In the prior art, a dialysis tube fixing device for hemodialysis patients, such as that disclosed in Publication No. CN214911375U, comprises a cannula assembly, a fixing plate, and a fixing mechanism. The cannula assembly includes a first dialysis cannula and a second dialysis cannula, both of which are mounted on the fixing plate. The fixing mechanism is capable of engaging the fixing plate. The first and second dialysis cannulae each define a semi-enclosed groove having a trapezoidal opening and capable of accommodating only one dialysis tube. The inner wall of the semi-enclosed groove is paved with an anti-slip layer. This increases the sliding resistance of the dialysis tube, limits its flexibility, improves its structural stability, facilitates hemodialysis operations, facilitates disinfection and cleaning of the dialysis tube, and facilitates the storage and organization of the dialysis tubes.

[0004] Although the above technical solution increases the sliding resistance of the dialysis tube, limits the flexibility of the dialysis tube, and improves the structural stability of the dialysis tube, it is inconvenient to heat the dialysis tube during use. When the difference between blood temperature and human body temperature is large, it is easy to increase the patient's discomfort. In view of this, a fixing device for dialysis tube is provided to overcome the above-mentioned defects. Utility Model Content

When the height of the device needs to be adjusted, the limit rod 91 provided on the mounting tube 9 is used to pull the pull plate 92 to move, thereby driving the limit rod 91 and the limit hole 94 to separate, and releasing the fixation of the fixed plate 5. At this time, the fixed plate 5 can be adjusted in the vertical direction to achieve the function of adjusting the height of the device, and the provided limit plate 10 can play a limiting role to prevent the fixed plate 5 from falling off due to excessive pulling. After the adjustment is completed, the pull plate 92 is released. During the process of the spring 93's own extension, the fixing ring on the limit rod 91 will be pushed to reset, thereby driving the limit rod 91 to be inserted into the limit hole 94 to fix the fixed plate 5 for easy use.
