[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

Embodiment 1

[0035] Such as image 3 As shown, it is a schematic diagram of a disposable precision filter infusion set for children, and the disposable non-polyvinyl chloride precision filter infusion set for children includes a bottle stopper piercer 1, a dripping funnel 4, and an injection part 6 connected through a pipeline 5 in sequence , liquid medicine filter 7, flow regulator 8, conical joint 9 and venous needle 10, the bottom of bottle stopper piercer 1 is connected with air filter 3, and the filter aperture of described air filter 3 and medicine liquid filter 7 is all 1 μm. The cork piercer 1, the housing of the air filter 3, the injection part 6, the housing of the liquid medicine filter 7, the flow regulator 8 and the conical joint 9 are all made of ABS (757K), and the dropping funnel 4 and The pipelines 5 are all made of TPO (EPDM+PP).

[0036] Such as Figure 5 As shown, it is a schematic diagram of an air filter, the air filter 3 includes an air outlet housing 31, the air ...

Embodiment 2

[0040] Similar to Example 1, the difference is that the filter pore size of the liquid medicine filter membrane 71 is 0.2 μm.

Embodiment 3

[0042] Similar to Embodiment 1, the difference is that the filter pore diameters of the liquid medicine filter membranes 71 are all 2 μm.

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...
