A simulation training device for puncturing arteriovenous fistula in patients with hemodialysis

Abstract

The invention discloses a simulated training device for puncturing an arteriovenous fistula of a patient on hemodialysis, comprising a workbench and a universal brake wheel. The bottom of the workbench is provided with a universal brake wheel. The bearing is provided with a support shaft, the outer wall of the support arm is sleeved with a direction adjusting sleeve, the side of the first fixing plate is rotatably connected with an extension screw, and the top outer wall of the support column is fixedly installed with a positioning rod, A direction adjusting support rod is fixedly connected to the outer wall of the support shaft, and a lifting rod is fixedly connected to the upper surface of the lifting screw. The simulated training equipment for puncturing the arteriovenous fistula of simulated hemodialysis patients is easy to hold the internal fistula models of different sizes stably, and the equipment is easy to adjust the spatial position of the internal fistula model, which is beneficial for the user to observe the puncturing effect of the internal fistula from multiple angles. At the same time, the internal fistula puncture simulation training equipment is convenient for storing tools, so as to avoid the phenomenon of losing training tools.

Description

technical field [0001] The invention relates to the technical field of medical treatment, in particular to a simulation training device for puncturing an arteriovenous internal fistula of a simulated hemodialysis patient. Background technique [0002] Hemodialysis is one of the treatment methods for patients with renal failure. The process is to drain the blood from the patient's body into a dialysis device composed of hollow fibers through equipment, remove metabolic waste from the patient's body, maintain acid-base balance and electrolytes, and then remove the patient's body. The excess water is then re-directed into the patient's body after purification, and an arteriovenous fistula is a surgical procedure used for hemodialysis treatment, in which an artery near the wrist and a nearby vein are sutured to form an arteriovenous fistula It can provide sufficient blood for hemodialysis and ensure the adequacy of dialysis treatment. Generally, the service life of internal fist...

Problems solved by technology

[0008] The purpose of the present invention is to provide a simulated training device for arteriovenous fistula puncture in simulated hemodialysis patients to solve the above-mentioned background technology. Stable clamping makes it inconvenient for users to perform puncture simulation training of different types of internal fistula, and it is not easy to adjust the space position of the internal fistula model for the internal fistula puncture simulation training equipment, which is not conducive to the user to observe the effect of internal fistula puncture from multiple angles. Fistula puncture simulation training equipment is inconvenient to store tools, and training tools are prone to loss, which reduces the practicality of the device
