Description

Technical Field

[0001] The utility model relates to the technical field of medical restraint, in particular to a restraint belt for hemodialysis patients which is easy to operate. Background Art

[0002] Hemodialysis refers to the use of a blood purification device to remove various toxins and excess water from the patient's blood, while replenishing various beneficial substances to achieve the purpose of purifying the blood. The fistula needle is an indispensable medical device in hemodialysis treatment. It is mainly composed of a stainless steel puncture needle tube, needle wings, tube body, catheter clamp, connector, etc. During hemodialysis treatment, the patient's arteriovenous fistula is punctured and connected to the extracorporeal circulation circuit and dialyzer to form an extracorporeal circulation pathway for blood.

[0003] During use, the existing restraint belt for hemodialysis patients can restrain the patients, but cannot perform hemodialysis on the patients, which reduces the use restrictions of the equipment. Therefore, the fistula needle needs to be taken out for hemodialysis after restraint, and the phenomenon of fixing the fistula needle on the restraint belt cannot be achieved. At the same time, the fistula needle cannot be clamped and fixed, resulting in the fistula needle being subjected to too little force when the restraint belt is used to remove the fistula needle, and remaining in the patient's body, causing secondary damage to the patient, reducing the diversity and fixation of the traditional restraint belt for hemodialysis patients. For this reason, a restraint belt for hemodialysis patients that is easy to operate is introduced. Utility Model Content

[0008] As a preferred technical solution of the utility model, the limiting rod is clamped in the groove of the placement groove, and the fixing plate is slidably connected to the inner wall of the telescopic shell.

[0009] As a preferred technical solution of the utility model, the limiting rod is slidably connected to the inner wall of the limiting groove, and the clamping block is made of rubber.

[0010] As a preferred technical solution of the utility model, there are four groups of the clamping blocks, the fixing plates and the limiting columns, and the four groups of the clamping blocks, the fixing plates and the limiting columns are respectively arranged in a ring shape on the top of the needle column.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The easy-to-operate restraint belt for hemodialysis patients can place the fistula needle by placing it into the needle wing shell and the needle column before restraining the patient.

At the same time, the button can be pressed again to retract the fistula needle, so that hemodialysis can be performed while restrained.

[0013] 2. The easy-to-operate restraint belt for hemodialysis patients, after placing the intravenous fistula needle, rotates the rotating plate to make the limit column slide in the groove of the sliding groove, thereby driving the fixed plate and the inner wall of the limit block to slide, so that the rotation of the rotating plate drives the restraint belt body to rotate, so that the restraint belt body has a contraction effect, thereby achieving the ability to adjust the pressure of the restraint belt body on the patient's puncture site, reducing the need for medical staff to press the skin to prevent blood from flowing out, and also achieving the fixation of the intravenous fistula needle, preventing the patient from slipping due to the insecure fixation of the intravenous fistula needle during the dialysis process, thereby causing secondary injury to the patient, so that the restraint belt body applies pressure to the patient's puncture site through rotation.
