Technical field
The present invention relates to a kind of medical instrument, more particularly to a kind of rotary anti-particle syringe.
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 impurity in liquid can be extracted into syringe, be injected into human body again, more not
Solvable particle such as syringe needle might have rubber plug particle etc. when penetrating into bottle cap, and entering human body as a kind of foreign matter cannot be by
Metabolism, can block lung or cardiovascular and cerebrovascular or form package in blocking local and be known as granuloma, cause human body it is long-term, it is potential
, irreversible damage, it is not only unhealthful or even cause life danger, particle pollution be the major issue that faces at present it
One.The patent of official seal micro particle filtering formula syringe is retrieved at present, and application No. is 201710869814.2, in syringe
Filter device is placed at nipple, on the one hand complicated one side is not accounted for due to being lengthened at nipple so that liquid retains yet
Increase, waste liquid, simultaneously because tiny at nipple, manufacture difficulty, cost are relatively high；The utility model patent one authorized
Kind of multifunctional injector ZL2016210698372, designs needles with two holes and in the filter device of pintle portion placing structure complexity,
Since pintle portion space is too small, complex process, realizes difficult, raising production and consumption charge；It does not account for when injection outside liquid
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, is not used only
Trouble needs to replace syringe needle repeatedly, in addition to inconvenient to use if when same branch syringe disposably needs secondary or pumping medicine three times
Also the problems such as easily causing germ contamination, not accounting for medicine liquid leakage when injection increases Medical Expense for Patients and waste health money
The advantages of source, rotary anti-particle syringe is simple for process, cost is more easy, through-hole and filter hole in the same plane, institute
When rotating do not have to change position, and provide a kind of antiparticulate filter.
Invention content
The invention aims to solve above-mentioned existing syringe without filter device, particle that can not be in filtering liquid medicine,
Enter human body there are insoluble micro-particle and cannot be metabolized during injection, heart and brain or pulmonary vascular can be blocked or in blocking local shape
It is known as granuloma at package, it is unhealthful or cause life danger, while complex process, cost are high, difficult realize, in injection process
There is the problems such as medicine liquid leakage, and a kind of rotary anti-particle syringe is provided.
A kind of rotary anti-particle syringe, including injection tube and injector push-rod, injector push-rod are arranged in injection tube
Interior, the upper end in the injection tube has filter device；
The injection tube upper end has baffle, has circular trough among baffle, has the second through-hole on circular trough；
It is respectively provided with first through hole and filter hole among the filter device, is provided with and is connected in first through hole and filter hole
Device, linker include through-hole cylinder and cartridge filter, and through-hole cylinder is staggeredly connected to setting with cartridge filter, has filter screen in cartridge filter, after
There is handle, filter device to be embedded in circular trough, can be rotated in circular trough at end；
The first through hole and filter hole both ends are respectively provided with elastic packing washer；
The first through hole and filter hole upper end can be connected respectively with nipple, and lower end can be connected respectively with the second through-hole
It is logical.
The operation principle and process of the present invention：
Filter device can be rotated as desired by rotating handle, convert the position of through-hole cylinder and cartridge filter, extract liquid
When, pull injector push-rod, through-hole cylinder upper end to be connected to teat seal, lower end is connected to the sealing of the second through-hole, and liquid leads to respectively
Nipple, through-hole cylinder and the second through-hole is crossed to be flowed into injection tube；When injecting drug, pass through rotatable handle filter device, filtering dress
Setting can rotate in circular trough, and after turning to designated position, cartridge filter upper end is connected to teat seal, and lower end and the second through-hole are close
Envelope connection pushes injector push-rod, liquid to flow out external, elastic packing washer by the second through-hole, cartridge filter and nipple respectively
It can prevent liquid medicine spill, filter screen that can be filtered to impurity and insoluble micro-particle etc..
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.
