Problems solved by technology

[0004] Dangerous, causing the harm of air embolism in patients due to air bubbles. Our company's authorized patent No. CN101780295A solves this problem. However, it is found in the application that this device can realize automatic exhaust, but the effect of stopping liquid is not good. This will lead to blood backflow easily due to failure to pull out in time after the injection, which will cause mental pressure on the patient. For this reason, further improvement is needed to enhance the hemostatic effect of the device

Abstract

The invention discloses a disposable infusion device. The infusion device includes an infusion catheter, a dropping hopper, an anti-bubble liquid dropping device, a dropper body, a liquid inlet hole,a dropper body fixing base, a dropper body connecting catheter, a vent hole, an air inlet plug, a liquid inlet pipe, a liquid inlet needle, an air pressure balancing needle, a balancing pipe and a heavy ion microporous film; the integral anti-bubble liquid dropping device is composed of the dropper body above, the dropper body fixing base in the middle, the dropper body connecting catheter below and the heavy ion microporous film fixed into the dropper body connecting catheter; by additionally arranging the heavy ion microporous film, after infusion is finished, partial medicinal liquid can remain on the heavy iron microporous film, blood reflux caused by complete dropping of the medicinal liquid is avoided, and liquid stopping is achieved at the same time; the infusion catheter and the dropping hopper adopt modified polyvinyl chloride as a raw material, not only is the physical mechanical performance of a traditional polyvinyl chloride material preserved, but also complete degradationis achieved, pollution is not caused to the environment, and environmental protection is facilitated. Moreover, since DEHP and other toxic additives are not added during preparation, important indicators such as heavy metal content and cytotoxicity are all superior to those of congeneric polyvinyl chloride products, and the infusion device is much safer to use.

Description

technical field [0001] The invention relates to a disposable infusion set, in particular to a safe and environment-friendly infusion set with functions of automatic exhaust and stop liquid, and capable of degrading. Background technique [0002] At present, PVC is generally used as raw material for the infusion tube, which is the main component of disposable infusion sets on the market. Although it has the advantages of excellent physical and mechanical properties, low price, and simple production process, the disadvantages of its PVC hose are extremely harmful, mainly as follows: 1. There are a large number of harmful substances in the production of PVC materials, and they must be added during processing. Toxic materials such as bis(2-ethylhexyl) phthalate (DEHP) are likely to cause disease hazards and unsafety for patients. In addition, the hydrolysis of DEHP will generate monoethylhexyl phthalate (MEHP) , its toxic and side effects are far higher than DEHP, and the hidde...
