Blood bag aseptic connection method and equipment used in the method

Abstract

Disclosed are a blood bag sterile connection method and a device used in the method. The device comprises a motor (12), a junction box (1), a PLC controller (11) and two vascular clamps (10). The junction box (1) is provided inside with a left scroll (3-1) and a right scroll (3-2), wherein a composite metal wire (4) on the left scroll (3-1) is connected with the right scroll (3-2). The method comprises the steps of: 1) placing blood bag pipes above the junction box (1), clamping a position to be cut using the vascular clamps (10) and simultaneously moving the two vascular clamps (10) in opposite directions; 2) heating the composite metal wire (4) and cutting the blood bag pipes using the composite metal wire (4); 3) after completing cutting, aligning the blood bag pipes to be connected; 4) moving the two vascular clamps (10) towards each other, rolling away the used composite metal wire (4) and rolling out a new composite metal wire (4); 5) connecting the blood bag pipes by heating the composite metal wire (4) and simultaneously moving the two vascular clamps (10) towards each other; and 6) returning the junction box (1) to the initial position, taking out the connected blood bag pipes and returning the vascular clamps (10) to the initial position.

Description

technical field

[0001] The invention belongs to the field of medical equipment, and in particular relates to a blood bag aseptic connection method and equipment used therefor. The method and device are used for cutting and connection of blood bag tubes. Background technique

[0002] At present, the traditional cutting sheet is used to cut and connect the blood bag tube. The cutting method of the cutting sheet is easy to realize, and the heat carried by the cutting sheet itself is large, which is easy to melt the blood bag tube. However, it is precisely because of the conventional cutting sheet It carries a lot of heat. During the connection process, the blood bag tubes undergo chemical changes and are thermally fused together. The excess heat of the cutting piece is actually a waste of energy, and the blood bag tubes absorb too much heat and it is easy to make the chemical change time Too long, it is not a reliable choice for clinical medicine.

[0003] Due to the reason wh...
