Electronic blood collection scale with function of automatic collection process terminating

Abstract

The invention discloses an electronic blood collection scale with a function of automatic collection process terminating. The electronic blood collection scale comprises an electronic blood collectionscale body, and the electronic blood collection scale body comprises a scale base, trays, an oscillating mechanism, weight acquisition sensors and displays. The oscillating mechanism (1-3), the weight acquisition sensors (1-4) and the displays (1-5) are all in circuit connection with a single-chip microcomputer. The electronic blood collection scale is characterized in that blood collection tubeclipping mechanisms (2) are arranged on the scale base (1-1) and connected with the single-chip microcomputer; when the weight acquisition sensors (1-4) detect that weights of blood in blood collection bags put in the trays (1-2) reach a set blood collection value, the single-chip microcomputer controls the blood collection tube clipping mechanisms (2) to clip blood collection tubes (M-1) of the blood collection bags. The technical problem that blood collection continues even when the blood in the blood collection bags is excessive in blood collection with an existing electronic blood collection scale can be solved.

Description

technical field [0001] The invention belongs to an electronic blood collection scale with the function of automatically terminating the collection process. Background technique [0002] We know that when the blood flows out of the body, it will coagulate in 2-8 minutes under normal conditions. However, the blood collected by blood donation will not coagulate in the blood collection bag, thanks to the anticoagulant in the blood collection bag. [0003] Existing electronic blood collection scales generally include a tray, a balance base, a display, a load cell, a swing mechanism, and the like. When blood is collected, in order to prevent the collected blood from coagulating, a certain amount of anticoagulant will be housed in the plastic blood collection bag. Place the blood collection bag on the tray of the electronic blood collection scale. During the blood collection process, the blood flows into the plastic blood collection bag, and the weighing tray of the electronic bl...

AI Technical Summary

Problems solved by technology

[0004] First, when the blood volume in the blood collection bag in the tray of the electronic blood collection scale reaches the set blood collection value, the staff needs to detect and close the blood collection tube in time. If it is not found or processed in time, there will be a problem of continuous blood collection

[0005] Second, the existing electronic blood collection scales are one-person-one-scale blood collection. When there are many blood collection people, a large number of blood collection scales need to be configured, which is costly and inconvenient to operate.
