Venous transfusion is the important means of routine clinical treatment, and infusion needs to use infusion apparatus；Infusion apparatus is a kind of master
It is used for venous transfusion, the disposable medical consumptive material by aseptic process；The operation principle of infusion apparatus is bottle under the effect of gravity
The interior thinner infusion tube of liquid runs down flows into Murphy's dropper, when Murphy's dropper water column pressure is more than vein pressure, in bottle
Liquid runs down hose flow into vein；Since different infusion apparatuses is not quite similar in function and structure, cause in infusion process
It is different with the filter effect of bubble to the particulate matter (most of diameters are at 15 μm or less) in liquid；These are insoluble
If it is clinical that particle and bubble into human body can cause patient infusion reaction, the reaction of pyrogen sample, phlebitis, Granuloma in lung etc. occur
Symptom is dealt with improperly or even can threaten patient vitals；The pore size filter of infusion apparatus is larger currently on the market, it is below to 5 μm not
Dissolubility particle can not effectively catching；Filter effect is poor, if but the aperture of filter membrane is too small, be easy to cause filter efficiency compared with
It is low, it is all easy to influence transfusion effect；Therefore, in order to solve problem above, it would be highly desirable to design a kind of infusion apparatus of optional filter.
Utility model content
A kind of in order to solve the above problems, the utility model proposes disposable precision filter infusion set, improved
Effect and filter efficiency are filtered, can also prevent from resulting in blockage because filtering dose is larger, influence to be infused.
The disposable precision filter infusion set of the utility model, including bottle plug puncture unit, and connect with bottle plug puncture unit
The dropping funnel connect, and the governor that is connect with dropping funnel, and the intravenous injector that is connect with governor its output end；The bottle stopper puncture
It is connected by woven hose between device, dropping funnel, governor and intravenous injector；Accurate mistake is installed between the dropping funnel and governor
Filter device；The precise filtering device includes feed liquor buffering bucket, and the accurate filter being connect with feed liquor buffering bucket, and with precision
Filter its output end connection goes out liquid buffering bucket；Described its liquid outlet of feed liquor buffering bucket and goes out liquid buffering bucket its inlet and pacify
Equipped with threeway seat；Its inlet hose of the accurate filter and its liquid outlet hose respectively with the threeway seat of feed liquor buffering bucket and
Go out the threeway seat connection of liquid buffering bucket；Its other end of the threeway seat of the feed liquor buffering bucket and go out the threeway seat of liquid buffering bucket it is another
One end is respectively fixed with sealing rubber plug；The feed liquor buffering bucket is connect with dropping funnel by woven hose；It is described go out liquid buffering bucket with
Governor is connected by woven hose.
As preferred embodiment, its other end of the threeway seat of the feed liquor buffering bucket and the threeway seat for going out liquid buffering bucket
Its other end is connected separately with another accurate filter.
As preferred embodiment, its filter membrane of the accurate filter is polyethers alum material.
Further, the intravenous injector includes needle stand, and the intravenous needle being connect by hose with needle stand；It is described
Intravenous needle outer sheath is equipped with needle guard.
Further, the infusion tube end of its output end of governor is equipped with connector；The connector and needle stand
Detachable installation.
Compared with prior art, the disposable precision filter infusion set of the utility model, it can root
According to two accurate filters of selection are needed, it can also select single accurate filter when using common drug, reduce cost；It is logical
It crosses and multiple accurate filters is set, improve filter effect and filter efficiency, can also prevent from causing to block up because filtering dose is larger
Plug, influences to be infused.
