Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of precision liquid medicine filter.
Background technology
As modern medicine is horizontal and the continuous improvement of people's living standard, clinical application particulate matter is to human body
Harm be commonly numerous medical personnels and recognized, while some patientss also by various approach to insoluble micro- in decoction
The harm of grain has recognized, and they increasingly strengthen clinical application quality and awareness of safety, it is desirable to also more and more higher.But current state
Syringe used in the clinic of interior in the market does not possess the function of the particulate matter in filtering liquid medicine, a large amount of insoluble in decoction
The careless decoction of particulate is injected in blood into the human body together.It is larger (to be more than blood vessel diameter, generally 6~8 μm of adult；Children
Particularly infant's capillary is typically up to thinner 2~3 μm) particulate can directly contribute local circulation obstacle and cause blood vessel bolt
Plug severe patient causes local stoppages and oxygen supply deficiency, and histanoxia produces oedema and inflammation；Can be direct with blood flow less than this footpath
Cause thrombus or because foreign matter intrusion tissue causes erythrocyte aggregation to increase volume around particulate, cause granuloma, and
Because quantity can equally cause blood vessel embolism more.In the present age, especially infant, children accept the risk more greatly, because human body capillary
Blood vessel is generally 6~8 μm, and children's particularly infant's capillary is typically up to thinner 2~3 μm, well imagines infant, youngster
Child undertakes great potential safety hazard when receiving medication.But do not have a kind of mistake of the progress medical filtration of simple possible now
Filter.
The content of the invention
To solve the problems, such as technological deficiency existing for existing syringe, the invention provides a kind of precision liquid medicine filter.Should
Not only cost is low for syringe, and filtering safe is easy to use, during dosing, make its directly filtered when preparing liquid particulate and
Precipitation, reach the effect of secondary filter, it is ensured that patient medication safety.
To reach above-mentioned purpose, the present invention uses following technological means：
A kind of precision liquid medicine filter, including：It is arranged on the filter being connected inside injection tube or with injection tube needle holder
Body, described filter body front end are tapering point, and rear end is filter end；Described filter body includes filter block and work
The dynamic floating plug being arranged on inside filter block, filter block inner side form filter chamber, annular filter film are set in filter chamber；Work as syringe
During drawing liquid, floating plug is moved to the floating plug channel roof of filter block, and liquid enters filter chamber from the blind hole of floating plug；When syringe discharge opeing
When, floating plug channel roof of the floating plug away from filter block, the liquid of filter chamber enters by annular filter film, filter block peripheral channel
The blind hole of floating plug.
Described floating plug is boss structure, and its axis is provided with blind hole, be provided with floating plug convex platform side wall with it is blind
The fluid hole and inlet opening of hole connection；Be provided with the floating plug passage with floating plug form fit in filter block, floating plug passage small end with
Filter chamber connects, and filter chamber is provided with annular filter film in addition to floating plug passage small end exports；The company of being additionally provided with filter block
Pass through filter chamber and the liquid outlet channel at the big end of floating plug passage；When the floating plug shaft shoulder and floating plug passage are adjacent to, blind hole by inlet opening with
Filter chamber connects, and fluid hole, liquid outlet channel are in sealing state；When the floating plug shaft shoulder and floating plug path clearance are set, blind hole is led to
Cross fluid hole, liquid outlet channel connects with filter chamber, inlet opening is in sealing state.
Described liquid outlet channel is multiple, and set along filter block axis.
Described fluid hole and inlet opening are circumferentially uniform along floating plug.
When filter body is connected with injection tube needle holder, the connecting hole of described filter end is connected with needle holder, even
Connect hole and the shape of needle holder outer wall matches, tapering point is used to connect with syringe needle.
When filter body is arranged on inside injection tube, size shape and the injection tube front end of described filter body
Inner chamber matches, and in tapering point insertion needle seat inner chamber, and injection tube inwall is tightly connected with filter body.
Described filter end inner chamber and the shape of the piston of injection rod front end matches.
Described annular filter film is nuclear pore membrane, poly (ether sulfone) film, polyester film or nylon membrane.
Described annular filter membrane filtration aperture is 1.2~15 microns.
Described needle holder and tapering point are nipple or quick connector.
Relative and prior art, the present invention have advantages below：
The decoction precision floating plug filter of the present invention, it can be used on syringe being placed on use in injection tube,
By including filter block with the use of medical filtration, filter is carried out with injection tube and being movably arranged on floating inside filter block
Plug, when syringe drawing liquid, floating plug is moved to the floating plug channel roof of filter block, and liquid enters filtering from the blind hole at floating plug center
Chamber, when syringe discharge opeing, floating plug channel roof of the floating plug away from filter block, the liquid of filter chamber is by annular filter film, mistake
Filter block peripheral channel enters the blind hole of floating plug.So as to realize that drawing liquid does not filter, the function of discharge opeing filtering.Filtering built in the present invention
Device does not cause other workloads to user, and the filtering of decoction has been carried out while normal use.Not only cost is low, mistake
Filter safety, it is easy to use, during dosing, visually it is not easy the particulate that finds and precipitation can be defeated with the thick syringe needle injection of syringe
In liquid bottle (bag), cause infusion safety hidden danger, and the problems such as these particulates are costly filtered using precision infusion set, make its with
Particulate and precipitation are directly filtered during liquid processed, reaches the effect of secondary filter, it is ensured that patient medication safety.
Further, floating plug is boss structure, the floating plug passage with floating plug form fit is provided with filter block, when floating plug axle
When shoulder is adjacent to floating plug passage, blind hole is connected by inlet opening with filter chamber, and fluid hole, liquid outlet channel are in sealing state；When
When the floating plug shaft shoulder is set with floating plug path clearance, blind hole is connected by fluid hole, liquid outlet channel with filter chamber, and inlet opening is in close
Envelope state.Compared with common syringe, it is simple to operate, it is easy to use, also with filtering function.
Further, the advantages of liquid outlet channel is centrally disposed is that decoction discharge is easy when center extrudes, discharge opeing extruding force
Small, filtering is abundant.When the distribution of feed pathway Central Symmetry can be easy to drawing liquid, be further separated into syringe, drawing liquid efficiency
It is high.
Further, the filter body inside injection tube is fabricated structure；It can individually manufacture, use during manufacture
When be combined again, be easy to manufacture and transport.
