Abstract

The invention discloses a model for simulating internal arteriovenous fistula vascular puncture. The model includes a storage box, wherein a simulation arm is arranged in the storage box; a simulatedarteriovenous blood fistula is connected between the simulated vein blood vessel and the simulated artery blood vessel; a cavity is formed in the bottom of the inner wall of the storage box; a bidirection screw rod is rotatably connected to the left side and the right side of the inner wall of the cavity through bearings; a fixing rod is fixedly connected to the front side, close to the top end, of the stretching-out mechanism, containing cavities are formed in the left side and the right side, close to the top of the storage box, of the storage box; the end, close to the push rod, of the pushing-out mechanism is hinged to the rear end of the push rod. According to the internal arteriovenous fistula puncture model, through cooperation of the structures, the problems that when the internalarteriovenous fistula puncture model is used, a puncture instrument is not easy to use, and the puncture process is not easy to record are solved; and meanwhile, after use, the internal arteriovenousfistula puncture model, the puncture instrument and the recording instrument are not easy to store and tidy, and inconvenience is brought to use.

Description

technical field [0001] The invention relates to the technical field of medical teaching equipment, in particular to a simulated arteriovenous fistula blood vessel puncture model. Background technique [0002] The prerequisite for hemodialysis is to have a reliable vascular access, and the quality of vascular access directly affects the patient's dialysis and quality of life. Foreign studies have shown that hospitalization due to vascular access has become a major issue for maintenance dialysis patients. The number one cause of the disease and a major contributor to medical costs. Arteriovenous fistula (AVF) refers to the vascular channel established by arteriovenous anastomosis under the skin. It is the most commonly used vascular access for hemodialysis patients and is called the "lifeline" of patients. Continuous education and training can reduce the occurrence of internal fistula complications, reduce the resulting medical costs, prolong the use of internal fistula, and ...
