Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of filtration syringe has and its technical scheme.
Background technology
At present, human body is subcutaneous, in terms of intracutaneous, muscle and intravenous injection, due to without can reliably provide a kind of safety
The effective filtering technique for directly using, employs the mode of liquid direct injection without filtering in clinic.It is clinical at present
The medicine equipments such as the middle syringe for using, dispensing injector with pin, injection needle and dispensing needle, without medical filtration function, injection needle or
Dispensing needle is arranged on syringe or dispensing injector with pin, and the core bar of emitter or dispenser is injected by drawing（Or piston）Complete liquid
Suction and the work such as human body is subcutaneous, intracutaneous, muscle, the injection of vein and the dissolving of liquid, preparation.Because these are used for people
Body is subcutaneous, the aseptic injection utensil of intracutaneous, muscle and intravenous injection or for liquid dissolving, the dispenser prepared and dispensing needle all
Filtering function without liquid, it is impossible to filter the particulate matter in liquid, and these particulate matters be typically derived from it is many
Pollution and syringe in the crystallization or liquid impurity and operating process of kind liquid are in itself.It is generally straight more than 5 microns
The particulate matter in footpath all has the property for causing capillary embolism, there is the risk of venous embolism more afterwards to patient.
In use of making up a prescription, to overcome this clinical difficulty problem, Partial Hospitals take liquid medicine filter and make up a prescription
The mode of syringe matched combined is used to filter during drug solution preparing the particulate matter more than more than 5 microns.But due to medicine
Liquid filter and dispenser are all the independent apparatus or accessory individually packed, and it has secondary pollution in anabolic process
（Such as open the air pollution twice after packaging, the environmental pollution in dismounting and installation process at least twice）, and due to combination and
Mounting-dismounting programme is strict and complicated, such as：Need to open packaging by sterile working requirement to accessory and apparatus respectively, enter by regulation requirement
Row installation at least twice（I.e. liquid medicine filter is first installed with dispenser, afterwards again enters dispensing needle with liquid medicine filter
Row is installed, and removes dispensing needle is installed with dispenser again after liquid medicine filter）Must be removed with after use（It is i.e. first
Remove the installation of dispensing needle and liquid medicine filter, then remove the installation of liquid medicine filter and dispenser, afterwards again by dispensing needle and
Dispenser is installed, and otherwise cannot just carry out feeding operations）, cause fluid loss and the loss of time, and to user or trouble
The fringe cost of person is also increased substantially.
The content of the invention
The technical problem of defect and presence for above-mentioned prior art, the present invention devise a kind of filtration syringe tool and
Its technical scheme, including medical filtration syringe, medical filtration injection needle, filtering dispensing injector with pin, filtering dispensing needle, injection
Liquid medicine filter and safety type medical filtration syringe, realize instrument used for injection to liquid source property particulate matter and injection with synchronous
The filtering of device source property particulate matter, realizes the i.e. injection i.e. filtering function of instrument used for injection during clinical injection, so that real
Show simplification, high efficiency, scientific, reliability, security and the economy of clinic medical filtration injection operation.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of filtration syringe tool, including upper shell, lower house, cavity, cut-off, liquid medicine filtering membrane, feed liquor control device and note
Penetrate control device；Liquid medicine filtering membrane top is divided into by feed liquor filter chamber and two, filter chamber of injection by cut-off in the upper shell
Chamber, the feed liquor filter chamber with feed liquor control device connect, the injection filter chamber connects with injection control apparatus；
The feed liquor control device includes feed liquor control room, unidirectionally controlled part, damping hole, damping keeper；
The injection control apparatus include injection room, unidirectionally controlled part, damping hole, damping keeper；
In a kind of above-mentioned technical proposal of filtration syringe tool disclosed by the invention, described liquid medicine filtering membrane is installed on upper shell
On upper or cavity, upper shell and liquid medicine filtering membrane form chamber and are separated into feed liquor filter chamber and injection filter chamber by cut-off,
Each independent feed liquor control device is provided with cavity and control device, feed liquor filter chamber, feed liquor control device, injection was injected
Control device, injection filter chamber are sequentially communicated；
In a kind of above-mentioned technical proposal of filtration syringe tool disclosed by the invention, the upper shell, lower house and cavity can be with
Using polypropylene for medical article, polyethylene, polyacrylonitrile-styrene-butadiene（ABS）Material or other medical macromolecular materials systems
Make, it would however also be possible to employ medical stainless steel material manufacture；
Another aspect of the present invention discloses a kind of technical scheme of filtration syringe tool：
When liquid suction is carried out, liquid enters the feed liquor filter chamber of upper shell, flows through liquid medicine filtering membrane, now, injection filtering
Unidirectionally controlled part in device is remained turned-off in the presence of Self-Closing and damping keeper, and under negative pressure state feed liquor
Unidirectionally controlled part in control room is opened, and after liquid is through the filtering of liquid medicine filtering membrane, is entered in syringe by feed liquor control room,
And the particulate matter that will be filtered out is intercepted and is retained in feed liquor filter chamber；When injecting liquid drug is carried out, pushed away in syringe core rod
Under the positive pressure of dynamic injection, by the self-acting of unidirectionally controlled part in feed liquor control room and in the effect of damping keeper
Under, unidirectionally controlled part in feed liquor control room is closed, while the unidirectionally controlled part in injection room at positive pressure is opened, warp
The liquid for crossing filtering for the first time is flowed through from injection room discharge after liquid medicine filtering membrane, it is secondary filter after not capacitive particulate intercept indwelling
In injection filter chamber, it is achieved thereby that the particulate matter after filtering can not be injected into human body and pollute other medicine again
The function of liquid or container.
A kind of filtration syringe that the present invention is provided has and its beneficial effect of technical scheme is：In not only solving clinic
It is applied in combination the secondary pollution problem of single liquid medicine filter and syringe and solves what operation sequence complexity was brought
Fluid loss, the loss of time, problem of environmental pollution, also solve it is irrealizable in existing clinical technology cannot be in vein and flesh
Medical filtration problem when meat is injected, so as to simplify, the operation of convenient clinical practice is required, effectively eliminates liquid and the time damages
Lose, effectively reduce the capillary embolism risk that particulate matter is caused to patient, effectively raise the rear matter of patient
Amount.
