Abstract
The utility model relates to a disposable filter for intravenous injection, which is composed of an upper small hopper and a lower small hopper which are combined and a piece of filtering film fixed at the middle part. When using, one end is directly connected with an injector and the other end is directly connected with a syringe needle. The utility model can block particles of 15 mu m to be injected into the blood vessel of a human body following the injection, avoiding harm to human bodies caused by particles.
Description
This utility model relates to a kind of disposable vein injection filter.
At present, when carrying out venous transfusion clinically because tube for transfusion is provided with ultimate filter, filtering the transfusion in a large amount of microgranules, reached the pharmacopeia prescribed limit.But, when carrying out intravenous injection, because there is not filter on the syringe, and very easily a large amount of microgranules of liquid in the syringe are injected human vas, for example: the organosilicon in the syringe, the glass fibre that the saw ampoule causes, drug crystallization, drug microparticles, apparatus contamination, environmental pollution etc., these particulate matters can cause certain harm to human body.
The purpose of this utility model is to provide a kind of disposable vein injection filter that can reduce these particulate matters.
This utility model is achieved in that it is to be merged by upper and lower two little funnels, filter membrane of center fixed and forming.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1, this utility model be upper hopper 1 and following funnel 2 both merge, filter membrane 3 of center fixed and composition, the aperture of filter membrane 3 is 9～10 μ m, during use, a termination syringe of upper hopper 1, a termination injection needle or a scalp acupuncture of following funnel 2.
This utility model can stop that the above microgranule of 15 μ m injects human vas with injection, and rejection rate reaches 97.2%, has reached the regulation of Chinese Pharmacopoeia, the harm of having avoided microgranule to cause to human body.
Claims (2)
