Embodiment Construction

[0017] A high-efficiency and low-resistance impurity particle filtration system for intravenous infusion, including a muphy-type dropper 1, an air filter 2 and a liquid medicine filter 3 communicating with it are arranged on the muphy-type dropper 1, and the air filter 2 It communicates with the right side of the upper part of the muphy dropper 1, and the air intake pipe 4 of the air filter 2 opens downward, and the liquid medicine filter 3 communicates with the left side of the lower part of the muphy dropper 1, and the muphy dropper 1 and The liquid medicine filter 3 is provided with a composite filter cloth 5 that separates it left and right and places it vertically. The composite filter cloth 5 is made by bonding a woven filter cloth and a polydimethylsiloxane filter membrane. The end of the inlet pipe 4 of the device 2 is provided with a composite filter cloth 5 placed horizontally.

[0018] The aperture of the composite filter cloth in the air filter 2 and the liquid med...

Abstract

The invention particularly discloses a high-efficiency and low-resistance impurity particle filter system for venous transfusion, solving the problem that an existing venous transfusion filter system is unreasonable in structure design and poor in filter effect, thus causing potential safety hazards. The high-efficiency and low-resistance impurity particle filter system for venous transfusion comprises a murphy's dropper, wherein the murphy's dropper is provided with an air filter and a liquid medicine filter which are communicated with the murphy's dropper; the air filter is communicated with the right side of the upper part of the murphy's dropper, and the opening of an air inlet pipe of the air filter is downward; the liquid medicine filter is communicated with the left side of the lower part of the murphy's dropper; each of the murphy's dropper and the liquid medicine filter is internally provided with composite filter cloth which is vertically placed; the two pieces of composite filter cloth respectively divide the murphy's dropper and the liquid medicine filter from left to right; each composite filter cloth is made by bonding woven filter cloth and a polydimethylsiloxane filter membrane, and the end part of the air inlet pipe of the air filter is provided with horizontally placed composite filter cloth. The filtering effect of the venous transfusion is improved by the high-efficiency and low-resistance impurity particle filter system, and then the potential safety hazards are completely eradicated.

Description

technical field [0001] The invention relates to a medical filter system, in particular to a high-efficiency and low-resistance impurity particle filter system for intravenous infusion. Background technique [0002] According to statistics, the annual output and annual sales volume of infusion solutions in my country have reached 15 billion bottles and 10.4 billion bottles respectively, among which more than 390,000 people died due to unsafe injections, and more than 2.5 million people caused adverse reactions. [0003] Unsafe injections are mostly due to the production process, production environment, infusion environment, human operation and other reasons. The following main tiny impurity particles are inevitably mixed in the finished infusion solution: carbon black particles produced during the production of liquid medicine; rubber particles and plastic particles; glass debris particles generated when ampoule is opened; crystal particles generated when adding drugs or mixi...
