Problems solved by technology

[0004] The purpose of the present invention is to provide a hemodialysis puncture needle stabilizer, which solves the problem of numbness and cramping in the arm of the existing patients when undergoing hemodialysis for a long time. The problem of bulge in the site, and the patient moves the arm inadvertently during hemodialysis or the puncture needle is connected to the catheter moves, which will cause the puncture needle to be unstable

Abstract

The invention discloses a hemodialysis puncture needle stabilizer. The stabilizer comprises a stabilizing arm seat, puncture needle tube fixing structures, arm restraint structures and blood-activating driving structures, wherein a pad is arranged inside the stabilizing arm seat, the left and right two sides of the stabilizing arm seat are fixedly provided with fixing plates, the puncture needle tube fixing structures are located above driving boxes, the left and right two sides of the pad are provided with the driving boxes, the arm restraint structures are installed on the top end of the stabilizing arm seat, the blood-activating driving structures are installed inside the driving boxes, and the outer sides of the output ends of the blood-activating driving structures are provided with driving position-limiting structures. According to the stabilizer, the symmetrical arrangement of the blood-activating driving structures and the driving position-limiting structures can simultaneouslysqueeze the arm from two sides during massage to avoid the problem of displacement of the arm, the fixing of the two parts of the arm and a connecting catheter can well stabilize a puncture needle, and at the same time, the installed pad with an elastic structure can also improve the comfort when the apparatus is used.

Description

technical field [0001] The invention relates to the technical field of dialysis auxiliary devices, in particular to a hemodialysis puncture needle stabilizer. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) with a similar concentration to the body are exchanged through diffusion / convection inside and outside the hollow fibers. , remove metabolic waste from the body, maintain electrolyte and acid-base balance; remove excess water from the body at the same time, and return the purified blood to the entire process called hemodialysis. Puncture needles are common medical devices that can be used to puncture organs and tissues or to inject drugs. [0003] When patients undergo hemodialysis, they may suffer from arm numbne...
