Description

Technical Field

[0001] The utility model belongs to the technical field of medical care, and relates to a hemodialysis tube fixing device. Background Technique

[0002] During hemodialysis, the tubing is often pulled and slipped due to patient movement and rescue during changes in the patient's condition. Clinically, we often use rubber bands, safety pins or adhesive tapes for fixation. However, these small fixation tools often fall off and are difficult to find during use, and they are likely to cause skin damage to patients, thus increasing the pain of patients and posing a safety hazard.

[0003] Patent CN213191614U discloses a hemodialysis tubing fixator, including a coiled sheet and a fixing part. The coiled sheet has a first state in which it is straightened and a second state in which it is curled. When the coiled sheet is in the second state, the coiled sheet is in the working state. The fixing part is fixedly connected to the coiled sheet, and a clamping position for clamping the hemodialysis tubing is provided on the fixing part. However, this patent is pasted on the bed rail or other bar-shaped structures. If the patient moves too much or turns over, it is easy to cause tubing traction or even pull out the entire hemodialysis tube, affecting the safety of clinical work.

[0004] Patent CN218900537U discloses an external fixation device for indwelling catheters in the necks of hemodialysis patients, including a first fixing band, a second fixing band, a fixing structure, and an adjusting structure. The surfaces of the first fixing band and the second fixing band are provided with a fixing structure, and the surfaces of the first fixing band and the second fixing band are provided with an adjusting structure. However, this patent uses Velcro to fix it on the patient's neck to achieve the purpose of protecting the safety of the hemodialysis tube. However, when it is fixed on the patient's neck, the entire neck is wrapped, and the skin condition of the puncture site cannot be observed. If there is bleeding, exudation, etc., it cannot be discovered in time. The dressing with bleeding is wrapped around the neck, which is likely to cause infection; at the same time, wrapping the Velcro around the entire neck of the patient is likely to rub the skin of the patient's mandible, and pressure sores and other conditions are likely to occur.

[0005] Moreover, the above patents can only adjust the tightness of the fixing device by reducing the tightness according to the size of the wearing position of the patient. The tightness of the fixing device can only be adjusted to the length of the fixing device at most. For some obese patients, a larger-sized fixing device needs to be customized, and the adaptability of the fixing device is poor. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a hemodialysis tube fixing device to overcome at least one defect of the above-mentioned existing technologies. The present utility model can achieve better fixation of the hemodialysis tube, adapt to different body parts of patients with different body types, and greatly change the tightness.

[0007] The purpose of the present utility model can be realized by the following technical solutions:

[0008] One of the technical solutions of the present utility model is to provide a hemodialysis tube fixing device, which includes a wearing strip, on which a fixing groove is provided, and a hemodialysis tube is installed and fixed in the fixing groove;

[0009] Both ends of the wearing strip are respectively provided with a male end and a female end. A male end buckle is telescopically arranged on the male end, and a female end buckle is slidably arranged on the female end. The tightness is adjusted by adjusting the telescopic length of the male end buckle and the sliding position of the female end buckle. The buckles are buckled and worn and fixed on different body parts of patients with different body types. At the same time, the buckles for buckling are made of a plastic material with a certain flexibility, which can be pressed and pulled out and loosened regularly to facilitate observing the covered part and prevent the occurrence of pressure sores.

[0010] As a preferred technical solution, two fixing grooves are provided on the wearing strip for the arterial end and the venous end of the hemodialysis tube to pass through, so as to play a better fixing role.

[0011] As a preferred technical solution, the size of the fixing groove is slightly larger than the outer diameter of the hemodialysis tube, so that the hemodialysis tube is fixed without slipping.

[0012] Further, a fixing sleeve is fixedly arranged on the male end, and a telescopic belt is telescopically arranged in the fixing sleeve.

[0013] Further, an adjusting knob is arranged on the fixing sleeve.

[0014] Further, the adjusting knob controls the telescopic length of the telescopic belt to expand the maximum diameter of the device after the buckles are buckled, which is especially suitable for the thighs of obese patients.

[0015] Further, a male end buckle is arranged at the end of the telescopic belt.

[0016] Further, a sliding sleeve is slidably arranged on the female end.

[0017] Further, a plurality of jacks are provided on the wearing strip.

[0018] Further, a plug is arranged on the inner side of the sliding sleeve.

[0019] Further, the sliding sleeve inserts the plug into the jack at the matching position to reduce the minimum diameter of the device after the buckles are buckled, which is especially suitable for the forearms of thin patients. When fixing the sliding sleeve, push the sliding sleeve inward, the plug is inserted into the jack, and when sliding the sliding sleeve, pull the sliding sleeve outward, and the plug is pulled out of the jack.

[0020] Further, a female end buckle is arranged on the sliding sleeve.

[0021] Compared with the prior art, the present utility model has the following beneficial effects:

[0022] (1) The fixing groove on this utility model can better fix the hemodialysis tube to prevent slippage, achieving better fixation of the hemodialysis tube.

[0023] (2) This utility model can adjust the tightness. The adjusting knob and jack on the side can adjust the fixing tightness according to the patient's fixed position by screwing out the telescopic belt of different lengths and inserting it into the jacks at different positions, adapting to different body parts of patients with different body types, greatly changing the tightness, and better protecting the safety of the pipeline when the patient turns over.

[0024] (3) This utility model is worn and fixed on the patient by buckling the male end buckle and the female end buckle, which is convenient for operation, can also be easily pressed and pulled out, and relaxed regularly, facilitating the observation of the covered part while preventing the occurrence of pressure sores.
