Background technology
In medical care, syringe is the most common type medical instruments, including intravenous injection, intramuscular injection, the heart
Interior injection, acupoint injection therapy etc. are required for using syringe, so far in clinical position there are no anti-micro particle filtering formula syringe,
So in injection process, the insolubility particle in liquid can be extracted into syringe, be injected into human body again, especially
It is that these insoluble micro-particles such as syringe needle might have rubber plug particle etc. when penetrating into bottle cap, enters people as a kind of foreign matter
Body cannot be metabolized, and can be blocked lung or cardiovascular and cerebrovascular or be formed package referred to as granuloma in blocking local, cause human body long-term
, potential, irreversible damage, it is not only unhealthful or even cause life danger, particle pollution be face at present it is important
One of problem.The patent for retrieving official seal micro particle filtering formula syringe at present is being noted application No. is 201710869814.2
Filter device is placed at emitter nipple, on the one hand complicated one side is not accounted for due to being lengthened so that liquid at nipple yet
Increase is retained, liquid is wasted, simultaneously because tiny at nipple, manufacture difficulty, cost are relatively high；The utility model authorized is special
A kind of multifunctional injector ZL2016210698372 of profit designs needles with two holes and is filled in the filtering of pintle portion placing structure complexity
It sets, since pintle portion space is too small, complex process, realizes difficult, raising production and consumption charge；Liquid when injection is not accounted for
The problems such as leakage；The disposable aspiration needle filter for molten of the existing sale in market needs to change syringe needle when taking out injection after medicine every time, not only makes
With trouble, need to replace syringe needle repeatedly if when same branch syringe disposably needs secondary or pumping medicine three times, except inconvenient to use
The problems such as also easily causing germ contamination outside, not accounting for medicine liquid leakage when injection, pusher advantage is than rotary user
Just, touch the position of i.e. convertible manhole appendix with hand, while in view of the particular/special requirement of sterile articles for use, ensure the opening of push plate with
It is extraneous obstructed, sterility requirements are more in line with, to sum up syringe filter device is difficult in the presence of manufacture, cost is high, inconvenient to use, medicine
The problems such as liquid leaks outside increases Medical Expense for Patients and waste health resources.
Invention content
The invention aims to solve above-mentioned existing syringe without opening on filter device, filtration syringe wall and the external world
It communicates, is likely to result in pollution；Particle that can not be in filtering liquid medicine, there are insoluble micro-particles to enter human body not during injection
It can be metabolized, heart and brain or pulmonary vascular can be blocked or form package in blocking local be known as granuloma, it is unhealthful or cause to give birth to
Critically ill danger, while complex process, cost are high, hardly possible is realized, have the problems such as medicine liquid leakage in inconvenient to use, injection process, and carry
For a kind of pusher Simple dustproof syringe.
A kind of push type Simple dustproof syringe, including injection tube and injector push-rod, injector push-rod setting are being noted
In shooting cylinder, which is characterized in that the upper end in the injection tube has filter device；

It is respectively provided with the second through-hole and filter hole on filter, there is filter screen, the second through-hole and filter hole in filter hole
Surrounding is respectively provided with seal washer, and filter both sides are respectively provided with arc-shaped slot, and the outer wall sealing of arc-shaped slot and injection tube is matched
It closes, filter is arranged in sliding slot, and the second through-hole and filter hole upper end are connected with nipple respectively, under the second through-hole and filter hole
End is connected with first through hole respectively.
The operation principle and process of the present invention：
When extracting liquid, nipple, the second through-hole are connected with first through hole, and injector push-rod, liquid is pulled to pass through respectively
Nipple, the second through-hole and first through hole enter in injection tube；
When injecting drug, first push filter, the arc-shaped slot of filter hole side is stuck on injection drum outer wall, and make nipple,
Filter hole is connected with first through hole, and injector push-rod, liquid is pushed to be flowed out respectively by nipple, filter hole and first through hole,
Impurity in filter screen filtration liquid, prevents insoluble micro-particle from entering in human body；
Seal washer is respectively provided with around second through-hole and filter hole can prevent overflow of drug fluid, the sealing of the first elastic sealing film
It is arranged at the first open slot, the sealing of the second elastic sealing film is located at the second open slot, the first elastic sealing film and the second bullet
Property diaphragm seal wrap up the both ends of filter respectively, prevent filter device contaminated.
Beneficial effects of the present invention：
The configuration of the present invention is simple, easy to operate, filter screen can effectively filter out the impurity in liquid, ensure liquid cleaning,
It is safe to use, medical staff's working efficiency is improved, injecting fluid endoparticle is can avoid and enters human body, ensure drug safety, prevent
Particle blocks heart and brain or pulmonary vascular, improves the safety to human body.
