Disposable precision filter infusion set for children

Abstract

The invention provides a disposable precision filter infusion set for children, which is characterized by comprising a bottle stopper puncture outfit, a drip bucket, an injection part, a liquor filter, a flow regulator, a conical joint and a deep vein trocar which are successively connected by pipelines, wherein the bottom part of the bottle stopper puncture outfit is connected with an air filter with a filtering aperture of 0.2mu m; and the filtering aperture of the liquor filter is 0.2-2mu m. The invention has the advantages of no toxicity or harm and good liquor filtering effect, and is suitable for infants and children to use.

Description

technical field [0001] The invention provides a disposable precision filter infusion set for children, which is especially suitable for clinical infusion of infants and children, and belongs to the technical field of infusion sets. Background technique [0002] Traditional infusion sets: generally divided into two types: "non-ventilated infusion set (with separate air intake device)" and "air intake infusion set", such as figure 1 As shown, it is a schematic diagram of a traditional non-air-intake infusion set. The non-air-intake infusion set is composed of a cork piercer 11, a dripping funnel 13, a flow regulator 15, and a liquid medicine filter connected through a pipeline 14 in sequence. 16 and a venous needle 17, and the dripping funnel 13 is provided with an injection part 12. Such as figure 2 As shown, it is a schematic diagram of a traditional air-intake infusion set, and the air-intake infusion set is composed of a cork piercer 21 connected through a pipeline 22 a...

Problems solved by technology

[0005] ② Poor filtering effect: Adult capillaries are generally 6-8 μm, and children, especially infants, are generally 2-3 μm thinner. General infusion sets are not divided into adults and children during the infusion process. The pore size is generally greater than 15 μm, and it cannot filter the small particles (greater than 2 μm) in the liquid medicine. Larger particles can directly cause local circulation disorders and cause vascular embolism. Severe cases cause local blockage and insufficient oxygen supply, and tissue hypoxia produces edema and inflammation. The blood flow smaller than this diameter can directly cause thrombus or cause red blood cells to gather around the microparticles due to foreign matter invading the tissue to increase the volume, resulting in granuloma, and because of the large number, it can also cause vascular embolism; at the same time, the microparticles in the infusion can also cause blood clots Phlebitis, allergic reaction, thrombocytopenia, bacteremia, allergic reaction, etc., the harm to the human body is latent and long-term

[0006] ③The liquid medicine filter does not have an exhaust design

When the air filter is used for clinical infusion, the liquid medicine is easy to flow out of the air filter, resulting in poor air intake of the air filter, or even no air intake, so that the clinical infusion cannot be performed, and the air intake part needs to be replaced
