Internal arteriovenous fistula functional exercise instrument and control method

Abstract

The invention provides an internal arteriovenous fistula functional exercise instrument and a control method. The functional exercise instrument comprises a cuff, a processor, an air pressure sensor, an inflation pump and an inflation tube; the cuff is provided with an inflation layer; the gas tube is connected between the inflation layer and an air nozzle of the inflation pump, so that the inflation layer, the inflation tube and the air nozzle of the inflation pump are co-formed an airflow passage; an output end of the air pressure sensor is electrically connected with an air pressure input end of the processor; the inflation control end of the processor is electrically connected with an inflation control end of the inflation pump. The cuff can be tied in a position, close to armpit, of an arm of a patient, and the inflation is started to inflate to the inflation layer of the cuff, the inflated cuff is pressed on blood vessels in the arm, so as to promote venous dilatation and internal fistula maturity. The exercise instrument is easy to operate, people can do exercises by self without any help of others, especially suitable for patients with poor blood vessel conditions, as well as the elderly, relatively poor stamina or relatively poor activity, and helps the patients to finish the functional exercise after the operation for the internal arteriovenous fistula.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an arteriovenous fistula function training instrument and a control method. Background technique [0002] Hemodialysis uses the principle of semi-permeable membranes to purify the blood and correct the water-electrolyte and acid-base balance through dispersion and removal of various harmful and redundant metabolic wastes and excess electrolytes in the fluid. Hemodialysis therapy introduces the patient's blood and dialysate into the dialyzer at the same time, uses the semipermeable membrane of the dialyzer to remove excess toxins and excess water accumulated in the blood out of the body, and supplements bases to correct acidosis and adjust Electrolyte disturbance, which replaces the excretory function of the kidneys. [0003] When performing hemodialysis therapy, the superficial vein of the patient is usually selected for acupuncture. However, due to insuffic...
