Semi-automatic twist-off equipment for blood bag internal card

Abstract

The invention discloses semi-automatic twist-off equipment for a blood bag internal card. The semi-automatic twist-off equipment comprises a supporting part, an action part and an electric control part, wherein the supporting part comprises a bottom plate, a supporting plate and a blood bag retaining card; the front surface of the supporting plate is fixedly provided with the blood bag retaining card; the action part comprises a motor and an internal card twist-off rod; the output shaft of the motor passes through the supporting part, and the tail end of the supporting plate is fixedly provided with the internal card twist-off rod; the internal card twist-off rod corresponds to the blood bag retaining card; the electric control part comprises a switch, an induction unit and an electric control unit; the induction unit comprises an induction block and an induction element; and the electric control unit is arranged on the upper surface of the bottom plate for cooperating with equipment to integrally act. The semi-automatic twist-off equipment is simple in structure, is convenient to use, is low in manufacturing cost, is easy to maintain, and makes up the blank of blood bag filling auxiliary machinery on the market. The semi-automatic twist-off equipment realizes semi-automatic twist-off of the blood internal card through a simple structure, replaces the original human labor, enables assembly line filling to be more stable and reliable, and is safer.

Description

technical field [0001] The invention relates to the field of blood preservation and filling, in particular to a semi-automatic twist-off device for a built-in card in a blood bag. Background technique [0002] Blood is composed of plasma and blood cells, among which plasma contains water, protein and low-molecular substances; blood cells include three types of cells: red blood cells, white blood cells and platelets. When blood is stored, the blood will be separated according to its composition, and then classified and filled. [0003] During blood filling, plasma bags in series are usually used as storage containers. During the filling process, the blood is continuously filled by twisting off the built-in cards in the inlet tubes of the adjacent blood bags one by one, that is, into the subsequent plasma bags. After the filling is completed, it will be packaged and stored in a unified manner. In the prior art, the above steps are all handled by manpower, and the built-in c...

Problems solved by technology

This method has certain disadvantages, the most important of which is that continuous repetitive work will cause local muscle fatigue, and the hands will become exhausted after working for a period of time, resulting in the inability to continue to cooperate with plasma filling work

For this process, there is currently no corresponding mechanical auxiliary equipment on the market.
