Upper limb supporting frame assembly for stem cell collection

Abstract

The invention discloses an upper limb supporting frame assembly for stem cell collection, and relates to the technical field of medical stents. The upper limb supporting frame assembly comprises an upper limb supporting part, wherein the upper limb supporting part comprises a length-adjustable forearm arc-shaped plate; one end of the forearm arc-shaped plate is rotationally connected with a hand arc-shaped plate; the bottom of the other end of the forearm arc-shaped plate is rotationally connected with a universal joint; and the movable end of the universal joint is fixedly connected with a shoulder arm arc-shaped plate. The upper limb supporting frame assembly has a reasonable structure, the angle and the position of each joint of the upper limb supporting frame part can be adjusted to meet the optimal comfort of a patient, the arm arc-shaped plate is bent at an angle relative to an armpit supporting block, arm and shoulder arm bending of the patient is simulated, and the forearm arc-shaped plate rotates and swings relative to the armpit supporting block to simulate a situation that the arm of the patient rotates and swings relative to the shoulder arm. Therefore, the normal movement operation of the upper limbs of the patient is simulated, pain and numbness caused by long-time immobility of the upper limbs of the patient are relieved, and comfort of the human body is achieved.

Description

technical field [0001] The invention relates to the technical field of medical supports, in particular to an upper limb support frame assembly for stem cell collection. Background technique [0002] At present, in the process of stem cell collection, it is necessary to puncture the veins of the elbow, drain the blood into the blood cell separator through the pipeline, enrich the hematopoietic stem cells by centrifugation, and return all the remaining blood components to you. The whole process It takes about 4 to 6 hours, which makes it uncomfortable for the collector to keep the arm in one position for a long time, which will lead to arm numbness; in addition, for the existing one-handed stem cell collection method, blood is collected from the artery at the wrist of one hand, and the blood is returned from the vein in the arm , The requirements for the arm fixation of the collector are higher, the angle of the functional position needs to be adjusted, and the wrist must also...
