A peripheral stem cell and bone marrow blood transfusion device

Abstract

The invention relates to the technical field of medical instruments and discloses a peripheral blood stem cell and marrow blood reinfusion device. The peripheral blood stem cell and marrow blood reinfusion device comprises an infusion tube; the infusion tube is made of a non-toxic and harmless material; the outer side of the infusion tube is fixedly provided with a pressure control bag and a protective shell; the pressure control bag is arranged above the protective shell; a partition plate is fixedly connected to the interior of the pressure control bag; and a communication hole is formed inthe left side of the top of the partition plate. For the peripheral blood stem cell and marrow blood reinfusion device, by installing the pressure control bag on the infusion tube, when in use, as blood below the partition plate in the pressure control bag slowly flows out, a floating plate slowly descends; when a pulling rope is straightened, a floating block starts to drive a pull rod to move downwards through the pulling rope, the pull rod pulls a sliding rod, the sliding rod vertically moves downwards, and a clamping rod is driven to move rightwards to enter a moving cavity through an inclined through hole; and the upper side and the lower side of the partition plate are communicated through an L-shaped hole, blood above the partition plate flows to the lower side, and after the clamping rod moves to the position below the partition plate, the structure is reset.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a peripheral stem cell and bone marrow blood transfusion device. Background technique [0002] With the continuous aggravation of environmental pollution in our country, various heavy metals exceed the standard, coupled with the increasingly chaotic work and rest time, people are more likely to suffer from blood diseases and kidney diseases. Currently, the treatment methods for these two types of diseases include hemodialysis and Bone marrow transplant, both of these treatments involve an exchange transfusion. [0003] During blood transfusion, hang the blood bag on a high place, so that the blood enters 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 too fast or too slow blood transfusion, but with the amount of blood in the blood bag As...

[0003] During blood transfusion, hang the blood bag on a high place, so that the blood enters 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 too fast or too slow blood transfusion, but with the amount of blood in the blood bag As the pressure in the blood bag decreases, the speed of blood transfusion may become slower and slower, which will bring discomfort to the human body and slow down the speed of blood transfusion. Therefore, we propose a peripheral stem cell and bone marrow blood transfusion device for the above problems. to solve the problem
