Description
Technical field
The present invention relates to a kind of medical apparatus, in particular to a kind of syringe with filtering function.
Background technique
In medical care, syringe is one of the most common type medical instruments, including intravenous injection, intramuscular injection, the heart
Interior injection, acupoint injection therapy etc. are required using syringe, so far in clinical position there are no anti-micro particle filtering formula syringe,
So in injection process, can by medical fluid or bottle stopper it is perverse fall particle be extracted into syringe, be injected again into the human body,
Especially some insoluble micro-particles such as syringe needle might have rubber plug particle etc. when penetrating into bottle cap, as a kind of foreign matter into
Entering human body cannot be metabolized, and can block lung or cardiovascular and cerebrovascular or form 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 current clinic to
One of the major issue that powder faces.The patent for retrieving official seal micro particle filtering formula syringe at present, application No. is
201710869814.2, filter device is placed at syringe nipple, on the one hand on the one hand structure is complicated does not account for yet
Due to being lengthened at nipple so that medical fluid retains increase, waste medical fluid, simultaneously because tiny at nipple, manufacture difficulty, cost are opposite
It is higher；A kind of multifunctional injector ZL2016210698372 of the patent of invention authorized designs needles with two holes and pacifies in pintle portion
Complicated filter device is put, since pintle portion space is too small, complex process, realizes difficult, raising production and consumption charge；
Not the problems such as not accounting for medicine liquid leakage when injection；The disposable aspiration needle filter for molten that market has sale is taken out equal when injection after medicine every time
Syringe needle is needed to change, not only using trouble, secondary or pumping medicine Shi Zexu is replaced repeatedly three times if same branch syringe disposably needs
The advantages of syringe needle, also easily causes germ contamination in addition to inconvenient to use, the return formula of elasticity anti-particle syringe be it is easy to use,
With hand flicking, that is, convertible two hole position, while in view of the factors such as liquid is exposed in injection process, it is provided with leak-proof device,
To sum up there is the problems such as manufacture is difficult, cost is high, inconvenient to use, medicine liquid leakage, increase patient medical in syringe filter device
Expense and waste health resources.
Summary of the invention
It, can not insolubility in filtering liquid medicine the invention aims to solve above-mentioned existing syringe without filter device
Particle, these particles can enter human body during injection to be metabolized, and can block heart and brain or pulmonary vascular or in obstruction office
Portion forms package and is known as granuloma, unhealthful or cause life danger, while complex process, cost are high, difficult realize, injected
The problems such as Cheng Zhongyou medicine liquid leakage, and a kind of syringe with filtering function is provided.
A kind of syringe with filtering function, including injection tube, injector push-rod, nipple and filter device, syringe
Push rod is arranged in injection tube, and nipple setting is arranged between injection tube and nipple in injection tube front, filter device；
The injection tube front is provided with sliding block mounting groove, closing piece mounting groove and spring mounting hole；
The filter device includes push rod, sliding block, filter screen, spring, closing piece, closing piece shaft, resets push rod and spring leaf,
Push rod is arranged on sliding block, and sliding block is arranged in sliding block mounting groove, and filter screen is arranged on sliding block, and spring one end is arranged in sliding block
On, the other end is arranged in spring mounting hole, and closing piece is mounted in closing piece mounting groove by closing piece shaft, and closing piece can turn around closing piece
Axis rotation resets push rod setting in closing piece tail end, and pressing, which resets push rod, can be such that closing piece rotates counterclockwise around closing piece shaft, spring leaf
One end setting is in closing piece tail portion, and other end setting is in closing piece installation groove sidewall；
First through hole, the second through-hole and closing piece card slot are provided on the sliding block；
The filter screen is arranged in the second through-hole；
The closing piece is used cooperatively with closing piece card slot；
The working principle of the invention and process:
When extracting medical fluid, sliding block state is as shown in Fig. 2, sliding block is in original state, first through hole and nipple and note at this time
Shooting cylinder connection, pulls injector push-rod, and medical fluid enters in injection tube by nipple, first through hole, after having taken out medical fluid, presses and push away
Bar, push rod drive slide block movement, and spring is compressed, and closing piece sticks into closing piece card slot when moving to certain position, slide position quilt
Fixed, the second through-hole is connected to nipple and injection tube at this time, and sliding block state is as shown in figure 4, push injector push-rod, medical fluid is through infusing
The filter screen inside the second through-hole is arranged in exhaustjet in the process in shooting cylinder, the second through-hole and nipple exhaustjet cylinder
The medical fluid of cylinder is filtered, and stays in insoluble microparticle inside injection tube, is extracted medical fluid if necessary to second, is pressed reset and push away
Bar, spring leaf are compressed, and closing piece rotates counterclockwise under the action of resetting push rod around closing piece shaft, and closing piece takes off out of closing piece card slot
From sliding block restores under the action of the spring to initial position, unclamps and resets push rod, and closing piece restores initial bit under spring leaf effect
It sets, first through hole is connected to nipple and injection tube at this time, continues second of extraction medical fluid.
When injecting drug, push rod is pressed, push rod drives slide block movement, and spring is compressed, closing piece when moving to certain position
It sticking into closing piece card slot, slide position is fixed, and the second through-hole is connected to nipple and injection tube at this time, injector push-rod is pushed,
The filter screen pair inside the second through-hole is arranged in the process through injection tube, the second through-hole and nipple exhaustjet cylinder in medical fluid
The medical fluid of exhaustjet cylinder is filtered, and stays in insoluble microparticle inside injection tube, prevents insoluble microparticle from entering in human body.
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 medical fluid, guarantee in medical fluid invariably
Solvable particle and the leakage of injection process Chinese medicine liquid, use is safe, improves medical staff's working efficiency, can avoid injecting fluid interior
Grain enters human body, guarantees drug safety, prevents particle blocking heart and brain or pulmonary vascular, improves the safety to human body.
