Straight pipeline liquid taking-out device and liquid taking-out method

Abstract

The invention discloses a straight pipeline liquid taking-out device. The straight pipeline liquid taking-out device comprises a main body, a puncture liquid-discharging part, a needle cylinder part and a blood bag pipeline bearing part; the main body is internally hollow, the puncture liquid-discharging part is arranged at one end of the main body and can slide relative to the main body, the needle cylinder part is fixedly arranged at the other end of the main body, the blood bag pipeline bearing part is movably arranged in the main body, the puncture liquid-discharging part is provided witha first puncture needle, and the needle cylinder part is provided with a second puncture needle. A liquid taking-out method comprises the following steps that S1, a blood bag pipeline loaded with to-be-taken-out liquid is fixed; S2, the two ends of the blood bag pipeline are punctured; S3, air is blown into the blood bag pipeline from one end of the blood bag pipeline; and S4, the to-be-taken-outliquid flows out from the other end of the blood bag pipeline. The structure is simple, operation is also very convenient, excessive financial burden is avoided even if single use, and thus the situation of liquid pollution due to repeated use is avoided.

Description

technical field [0001] The invention relates to the technical field of blood component packaging, in particular to a straight-tube liquid take-out device and a liquid take-out method. Background technique [0002] In recent years, a treatment for moderate to severe xerophthalmia by bioremediation of autologous serum extracted from whole blood has emerged. Autologous serum contains rich autologous active polypeptide small molecule repair factors and cohesin, which can effectively activate the resecretion of lacrimal glands, repair the function of lacrimal glands, and greatly relieve the symptoms of dry eyes - red eyes, foreign body sensation in eyes, dry eyes, and achieve relief and The purpose of curing eye dryness. At the same time, due to the application of autologous serum, there is no rejection, no allergic reaction, no toxic and side effects, and it is 100% safe. It is a new biological therapy for the treatment of dry eyes with an incidence of more than 20%. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] However, because the reagent itself is relatively thin, the traditional method is to cut one end of the blood bag pipeline, but there are the following problems: 1. Autologous serum is prone to overflow after cutting, resulting in waste of autologous serum; When opening the blood bag pipeline, they do not pay special attention to the disinfection of the scissors, resulting in the contamination of autologous serum when cutting the blood bag pipeline.
