Self-adjusting uniform speed reinfusion device and adjustment method for peripheral stem cells and bone marrow blood

Abstract

The invention discloses a self-adjusting constant-speed feedback device for peripheral stem cells and bone marrow blood and an adjusting method thereof. The feedback device comprises an infusion tube;the infusion tube is made of a non-toxic and harmless material; a pressure control bag and a protective shell are fixedly arranged on the outer side of the infusion tube; the pressure control bag islocated above the protective shell; a partition plate is fixedly connected to the interior of the pressure control bag, and a communicating hole is formed in the left side of the top of the partitionplate. According to the peripheral stem cell and bone marrow blood feedback device, the pressure control bag is arranged on the infusion tube; during use, blood slowly flows out along with blood belowthe partition plate in the pressure control bag; a floating plate slowly descends, when a pull rope is straightened, a floating block starts to drive a pull rod to move downwards through the pull rope, the pull rod pulls a sliding rod, the sliding rod vertically moves downwards, an inclined through hole drives a clamping rod to move rightwards to enter a movable cavity, the upper side and the lower side of the partition plate communicate with each other through an L-shaped hole, and after blood above the partition plate flows downwards and the clamping rod moves below the partition plate, thestructure resets.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a self-adjusting uniform reinfusion device and an adjustment method for peripheral stem cells and bone marrow blood. Background technique [0002] With the continuous increase of environmental pollution in my country, various heavy metals exceeding the standard, and the increasingly chaotic work and rest time, people are more likely to suffer from blood diseases and kidney diseases. The current treatment methods for these two types of diseases include hemodialysis and Bone marrow transplantation, both of which involve exchange blood. [0003] During blood transfusion, hang the blood bag at a high place to allow the blood to enter the human body through the pipeline, and at the same time adjust the blood flow speed according to the human body condition, so that the patient will not feel uncomfortable due to the blood transfusion being too fast or too slow, but with the a...
