Description
Technical field
The present invention relates to a kind of medical instruments, in particular to a kind of syringe needle 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, and the syringe needle of front end of the syringe needle be always numerous medical instrument manufacturers and
The emphasis of scientific research personnel's concern.There are no anti-micro particle filtering formula syringes in clinical position so far, also without anti-particle mistake
Syringe needle is filtered, so the impurity in medical fluid can be extracted into syringe, be injected into human body, especially in injection process again
It is that some 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 retrieves the patent of official seal micro particle filtering formula syringe at present, application No. is 201710869814.2, is infusing
Filter device is placed at emitter nipple, on the one hand on the one hand structure is complicated does not account for due to lengthening at nipple so that medical fluid yet
Increase is retained, medical fluid is wasted, simultaneously because tiny at nipple, manufacture difficulty, cost are relatively high；The patent of invention one authorized
Kind of multifunctional injector ZL2016210698372, designs needles with two holes and in the filter device of pintle portion placing structure complexity, by
Too small, complex process, realization difficulty, raising production and consumption charge in pintle portion space；Medicine liquid leakage when injection is not accounted for
The problems such as；The disposable aspiration needle filter for molten that market has sale needs to change syringe needle when taking out injection after medicine every time, and fiber crops are not used only
Tired, if same branch syringe disposably needs, secondary or pumping medicine Shi Zexu replaces syringe needle repeatedly three times, in addition to inconvenient to use
Germ contamination is easily caused, to sum up the Related products such as current syringe filter or patent have manufacture difficulty, cost height, use
The problems such as inconvenience, waste health resources, increases Medical Expense for Patients and waste health resources.
Summary of the invention
The invention aims to solve in above-mentioned background technique, existing syringe, can not filtering liquid medicine without filter device
In insoluble micro-particle, entering human body there are insoluble micro-particle during injection cannot be metabolized, and can block heart and brain or lung
Blood vessel forms package in blocking local and is known as granuloma, unhealthful or cause life danger, while complex process, cost
High, difficult to realize, is inconvenient to use, wasting the problems such as health resources, this patent places filter device at syringe needle, manufactures well, makes
Valence is low, it is easy to use, also do not change syringe construction without replacing syringe needle, and provide a kind of syringe needle with filtering function
Head.
A kind of syringe needle with filtering function, including needle main body, the first strainer, the second strainer, the first ball
With the second ball, the first strainer is arranged inside needle main body, and the second strainer is arranged inside needle main body, the setting of the first ball
Inside needle main body, the second ball is arranged inside needle main body；
The needle main body is internally provided with first passage and second channel；
The first rounding taper hole is provided on the first passage；
The second rounding taper hole is provided on the second channel；
The first rounding taper hole is opposite with the direction of the second rounding taper hole；
First strainer is arranged in the first rounding taper hole front；
Second strainer is arranged in the second rounding taper hole front；
First ball is arranged among the first strainer and the first rounding taper hole；
Second ball is arranged among the second strainer and the second rounding taper hole；
The working principle of the invention and process:
When extracting medical fluid, medical fluid is respectively enterd in first passage and second channel, when medical fluid passes through first passage, the
One ball moves backward, the first rounding taper hole open, first passage is unimpeded, when medical fluid passes through second channel, the second ball to
After move, the second rounding taper hole is blocked by the second ball, and second channel is closed, medical fluid through first passage, the first rounding taper hole and
First strainer enters syringe, and when by the first strainer, the first strainer once filters medical fluid, and particle stays in the first strainer
Surface.
When liquid medicine injection, medical fluid is respectively enterd in first passage and second channel, when medical fluid passes through first passage, first
Ball travels forward, and the first rounding taper hole is blocked by the first ball, and first passage is closed, when medical fluid passes through second channel, the
Two balls travel forward, and the second rounding taper hole is opened, and second channel is unimpeded, and medical fluid is through second channel, the second rounding taper hole and the
Two strainers enter human body, and when by the second strainer, the second strainer carries out second to medical fluid and filters, and particle stays in the second strainer table
Face.
Beneficial effects of the present invention:
The configuration of the present invention is simple, it is easy to operate, medical fluid is filtered twice, filter screen can be filtered out effectively in medical fluid
Particle improves medical staff's working efficiency, can avoid injecting fluid endoparticle and enters human body, guarantees drug safety, prevent particle
Heart and brain or pulmonary vascular are blocked, the safety to human body is improved.
