Background technology
It is well known that be encapsulated at present the injection of Clinical practice in vial more, with the syringe needle of syringe prick rubber stopper or
When vial extraction decoction is cut with emery wheel, bottle stopper material bits or glass powder can enter in parenteral solution.Traditional syringe does not have
There is filtering function, these impurity can be extracted into syringe when extracting liquid medicine and direct injection is to patient, so as to induce quiet
The diseases such as arteries and veins inflammation.
Chinese invention patent CN103721322A, discloses a kind of filter-type syringe, including syringe and filtering are injected
Pin, the injection needle is made up of needle tubing and needle stand, and needle tubing is arranged on the front end of upper needle stand, and the rear end of lower needle stand is connected to syringe
Conehead on, the front end of lower needle stand combines to form with upper needle stand and is provided with check-valves on imbibition entrance and injection outlet, lower needle stand,
Injection direction of the check-valves in the imbibition direction of imbibition entrance and injection outlet is opened, and injection is provided with filter in outlet.By
In designing feed pathway and liquid outlet channel simultaneously in the limited physical dimension of needle stand, cause two passages all narrow, and only
Return valve and form obstacle before liquid passage is crossed, liquid extracting and pushing resistance can be influenceed, cause liquid extracting and pushing to be exerted oneself all more conventional common
Injection needle significantly increases, and narrow and small passage covers filter membrane again during drawing liquid, enters flow velocity slowly, adds the work of medical personnel
Make intensity and working time, cause clinic can not receive application.Secondly, when drawing liquid is with liquid is pushed away, check-valves shape will first be washed open
Into liquid passage is crossed, once washing passage open, moment resistance diminishes, easily right especially when pushing away liquid injection, it is impossible to control injection speed
Patient damages.Furthermore, the feed liquor of check-valves, which stops liquid structure and going out liquid, stops feed liquor structural integrity, and in drawing liquid, feed liquor stops
Going out liquid structure and packing up can pull out liquid to stop feed liquor structure, cause liquid outlet to open, and cause decoction to enter from non-filtered passage and note
In emitter so that decoction impurity is not filtered completely, causes product design concept to lose meaning.
Utility model content
The purpose of this utility model is to provide a kind of multi-purpose filtering of stopcock formula simple in construction, easy to operate, safe
Type syringe, is especially suitable for Clinical practice.
The technical solution of the utility model is：
A kind of stopcock formula uses filter-type syringe, including syringe and injection needle, and the injection needle includes needle tubing and pin
Seat, needle tubing is arranged on the front end of needle stand, and the rear end of needle stand is connected on syringe, and four-way rotary valve, described four are set in needle stand
Way rotary valve includes housing, and the two ends of housing are connected with syringe and injection needle respectively, rotatable in housing to be provided with spheroid,
A channel interior in cross passage, cross passage is provided with spheroid and is vertically provided with filter membrane, hull outside sets rotation head, rotation head connection
On spheroid lateral wall.
The rotation head includes connecting portion and handle, and one end of connecting portion is connected with the lateral wall of spheroid, connecting portion it is another
One end is stretched out housing and is connected with handle.
The connecting portion is perpendicular to plane where cross passage, and the handle and connecting portion are perpendicular.
The cross vias inner walls are provided with annular groove, and the edge of the filter membrane is welded in annular groove.
The handle is plane where capstan handle, capstan handle and plane parallel where cross passage.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, drawing liquid and liquid process is pushed away
Middle Chinese medicine liquid filtering more facilitates；With simple in construction, easy to operate, medical filtration is complete, safe, Clinical practice is convenient
The advantages of.

Embodiment
As Figure 1-Figure 2, a kind of stopcock formula of the utility model uses filter-type syringe, including syringe 1 and injection
Pin 2, the injection needle 2 includes needle tubing 3 and needle stand 4, and needle tubing 3 is arranged on the front end of needle stand 4, and the rear end of needle stand 4 is connected to injection
On device 1, four-way rotary valve 5 is set, the four-way rotary valve 5 includes housing 6 in needle stand 4, the two ends of housing 6 respectively with syringe
1 is connected with injection needle 2, and rotatable be provided with spheroid 7, spheroid 7 is provided with cross passage 8 in housing, one in cross passage 8
Channel interior is vertically provided with outside filter membrane 9, housing 6 and sets rotation first 10, and rotation first 10 is connected on the lateral wall of spheroid 7.
The rotation first 10 includes connecting portion 11 and handle 12, and one end of connecting portion 11 is connected with the lateral wall of spheroid 7, even
The other end of socket part 11 stretches out housing 6 and is connected with handle 12.
The connecting portion 11 is perpendicular to the place plane of cross passage 8, and the handle 12 and connecting portion 11 are perpendicular.
As shown in figure 3, the inwall of cross passage 8 is provided with annular groove 13, it is recessed that the edge of the filter membrane 9 is welded on annular
In groove 13.
As shown in figure 4, the handle 12 is capstan handle 14, the place plane of capstan handle 14 where cross passage 8 with putting down
