Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, in particular to an anti-slip fixing device for a hemodialysis puncture needle. Background Art

[0002] Hemodialysis is one of the main ways to replace renal function for patients with end-stage renal disease. During the hemodialysis process, a puncture needle needs to be accurately inserted into the patient's blood vessels to establish extracorporeal blood circulation. To ensure smooth treatment, the puncture needle must be firmly and reliably fixed to the patient's body surface.

[0003] The existing method of fixing the puncture needle mainly adopts simple bandaging with tape or bandage. This traditional fixation method has many shortcomings. The adhesive tape or bandage has poor viscosity and is easily loosened due to patient activity or sweating. Therefore, the probability of the puncture needle slipping is high, which will not only interrupt the treatment but also threaten the patient's life safety. For this reason, we propose a hemodialysis puncture needle anti-slip fixation device. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a hemodialysis puncture needle anti-slip fixing device, which is designed with a sliding cover that can be slid to disassemble and adjust the position of the sliding cover, thereby facilitating the adjustment of the position of the fixing mechanism and the heating mechanism at the top of the sliding cover. After the position is determined, the rubber arranged on the outside of the limit slider can play a fixing role, thereby ensuring the stability of the fixing mechanism and the heating mechanism, preventing the drainage tube from loosening due to activities or sweating of the patient, thereby avoiding the risk of the puncture needle slipping and improving safety.

[0008] As a preferred technical solution of the utility model, a plurality of the fixing mechanisms are provided, and the plurality of the fixing mechanisms are equidistantly distributed.

[0009] As a preferred technical solution of the utility model, a warming cloth is laid on the inner bottom of the base.

[0010] As a preferred technical solution of the utility model, the cross section of the pressure ring is a semicircular arc structure, and an arc-shaped protrusion is provided on the inner side of the pressure ring.

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

[0012] 1. The sliding cover is designed so that the sliding cover can be disassembled and its position can be adjusted by sliding, so that the position of the fixing mechanism and the heating mechanism on the top of the sliding cover can be adjusted conveniently.

[0022] Hemodialysis is one of the main ways of renal replacement therapy for patients with end-stage renal disease. During the hemodialysis process, a puncture needle needs to be accurately inserted into the patient's blood vessels to establish extracorporeal blood circulation. To ensure the smooth progress of the treatment, the puncture needle must be firmly and reliably fixed on the patient's body surface. When the patient needs to undergo hemodialysis puncture, first, the two drainage tubes are distributed and inserted into the fixing mechanism 3 and the heating mechanism 4, and then the arm is placed inside the base 1, and the limiting slider 6 is inserted into the limiting slide groove 5, and the sliding cover 2 is slid until the sliding cover 2 is directly above the base 1, and then the puncture needle is punctured, and the puncture site is fixed with tape, and then the position of the two drainage tubes is stretched, and then the rotating block 9 is rotated to drive the screw 10 to rotate, and under the action of the thread, the pressure ring 8 is driven to move downward, thereby fixing one of the drainage tubes, and then the Velcro is used to wrap and fix the other drainage tube, and the operation is completed. By designing the sliding cover 2, the sliding cover 2 can be slid to disassemble and adjust the position of the sliding cover 2, so as to facilitate the adjustment of the position of the fixing mechanism 3 and the heating mechanism 4 at the top of the sliding cover 2. After the position is determined, the rubber set on the outside of the limit slider 6 can play a fixing role, ensuring the stability of the fixing mechanism 3 and the heating mechanism 4, avoiding the patient's activities or sweating, etc., which may cause the drainage tube to loosen, thereby avoiding the risk of the puncture needle slipping off and improving safety.
