Description

Catheter fixing device for hemodialysis of nephrology department Technical Field The utility model relates to the technical field of medical instruments, in particular to a catheter fixing device for hemodialysis in nephrology department. Background Hemodialysis is a common kidney function substitution treatment method, and blood of a patient is led out of the body through hemodialysis equipment to be purified and then returned into the body, so that the aims of removing toxins in the body and regulating water electrolyte balance are fulfilled. During dialysis, the patient is connected to the device via a catheter, and the stability of the catheter has an important influence on the safety and comfort of the dialysis process. The catheter fixing device in the prior art adopts a bracket or a base structure, and adapts to the body positions of different patients or the placement positions of equipment by adjusting the height of the bracket. However, conventional fixtures typically use a screw, threaded rod structure for height adjustment. Although such a structure has a certain flexibility, it takes a certain time to complete, and it is difficult to quickly adjust to a proper height in an emergency. For medical staff, the convenience of using of this kind of design is lower, probably influences treatment efficiency. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a catheter fixing device for hemodialysis in nephrology department. In order to achieve the above object, the technical scheme of the present utility model is as follows: The catheter fixing device for hemodialysis in nephrology department comprises a clamping plate clamped at the edge of a nursing bed and a supporting ring positioned above the clamping plate, wherein the side wall of the clamping plate is fixedly provided with a vertical rod, the section of the vertical rod is regular polygon, and each side wall of the vertical rod is provided with a clamping groove; The side wall of the vertical rod is sleeved with a sleeve plate in a sliding manner, the shape of the inner hole of the sleeve plate is fit with the shape of the section of the vertical rod, and the bottom of the sleeve plate is rotatably provided with a sleeve ring; The circumference of the inner side wall of the lantern ring is provided with a plurality of clamping blocks, and when the lantern ring rotates, the clamping blocks are driven to rotate so that the clamping blocks are clamped into the clamping grooves or rotate out of the clamping grooves. Preferably, when the clamping block rotates out of the clamping groove, the clamping block is close to one side of the side wall of the vertical rod, which is far away from the clamping groove. Preferably, the cross section of the vertical rod comprises an equilateral triangle structure or a square structure. Preferably, a first magnet is disposed on a side of the clamping groove, which is close to the side line of the vertical rod, a second magnet is disposed on a side of the clamping block, which is close to the first magnet, and the first magnet attracts the second magnet when the clamping block rotates to clamp into the clamping groove. Preferably, a cross rod is fixed at the top of the sleeve plate, a chute along the length direction of the cross rod is formed in the cross rod, and the support ring is slidably clamped in the chute of the cross rod. Preferably, the bottom of the clamping plate is connected with a locking screw for fixing. Compared with the prior art, the utility model has the beneficial effects that: 1. When the height of the support ring needs to be adjusted so as to support and fix the guide pipe, the lantern ring is rotated to drive the clamping block to rotate out of the clamping groove of the vertical rod, the lantern ring after rotation is dragged upwards, the lantern ring carries the sleeve plate and the cross rod to move upwards, the height of the support ring can be adjusted, the operation is simple and convenient, and the height of the support ring can be adjusted rapidly. 2. When the lantern ring drives the clamping block to rotate, the clamping block can slide the lantern ring and the sleeve plate after rotating out of the clamping groove of the vertical rod, and the force of the clamping block away from the clamping groove can be kept when the lantern ring slides, so that the lantern ring can stably slide and can not be clamped in the sliding process.
