Description
Technical field
It is a kind of syringe particularly the present invention relates to a kind of medical instruments.
Background technology
Fixed-quantity injector is used in the self-service treatment of patient, when carrying out rehabilitation or chronic disease maintaining treatment, user
Daily a certain amount of medicine is injected to oneself；Due to patient and non-professional medical personnel, therefore, occur in injection various
The wrong or nervous error caused of various kinds, after injection there is also with pin it is safe the problem of；Therefore, traditional fixed-quantity injector
Many inconveniences are there are, still there are many deficiencies urgently to improve.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of quantitative Needleless injection pen, the injection pen injects medicine using high-pressure jet
Thing, safety, health, efficient, mitigation patient suffering, improves the accuracy and security of injection.
To solve the above problems, the technical solution adopted in the present invention is：This quantifies Needleless injection pen and includes and coaxially set
The tip of the brushstyle of a writing or painting, rotating cylinder and the handle put；The rotating cylinder can freely be rotated around axle, during drum rotation, relative to the tip of the brushstyle of a writing or painting and handle
Seam crossing keeps airtight；
The tip of the brushstyle of a writing or painting includes containment vessel and the sealing block being placed in inside containment vessel, is provided with inwardly in the one side of the sealing block
The injection groove of depression, is provided with injection-tube in the another side of sealing block, is connected between injection groove and injection-tube by flow-limiting valve；Institute
The outside for stating containment vessel is provided with dismountable liquid storing tube, and the liquid storing tube is connected by metering hole with injection groove；
Accumulator is installed in the handle inner, one end of the accumulator is fixedly connected with handle, the other end of accumulator
It is fixedly connected with rotating cylinder；
Pushing block is movably set with the rotating cylinder, is tightly connected between pushing block and rotating cylinder by screw thread, the push side of pushing block with
The injection groove form fit；In the state of flow-limiting valve and current limliting bore closure, pushing block, rotating cylinder, sealing block form airtight deposit
Medicine chamber；Counting scale is provided with outside the rotating cylinder, the counting scale is engaged with rotating cylinder；
Guide rod is further fixedly arranged in the rotating cylinder, the pilot hole matched with guide rod is offered on the pushing block；Institute
Stating pushing block can reciprocatingly slide along guide rod.
The beneficial effects of the invention are as follows：Under nature, pushing block is close to injection groove, and medicine-storing cavity keeps squeezing flat state, do not had
There is the residual of medicine；When needing injection medicine, rotating cylinder directional rotating is rotated, and then accumulator is carried out to fill energy；Meanwhile, rotating cylinder
Pushing block translation is driven, the distance between pushing block and injection groove gradually increases, and medicine-storing cavity becomes larger, and now decoction is from liquid storing tube
Outflow；While drum rotation, the number of turns that counting scale is fixed with synchronous axial system, drum rotation, and then drive pushing block translation
Fixed distance, the decoction now drawn in medicine-storing cavity is fixed, and the amount of the decoction is corresponding with the numerical value of counting scale；
Under the limitation of flow-limiting valve and metering hole, decoction can only enter medicine-storing cavity from liquid storing tube, then flow out to note from medicine-storing cavity
Penetrate pipe；Containment vessel is compressed into skin, injection-tube unclamps rotating cylinder just to skin histology, and the energy being now stored in accumulator is fast
Quick-release is put, and drives rotating cylinder to rotate backward, and then promotes the translation of pushing block snap back, during pushing block rapid translation, medicine
Liquid is sprayed at a high speed with superfine fluid column from injection-tube, now forms high speed fluid column, injects the subcutaneous of human body；Pushing block presses injection
Groove, internal decoction is completely exhausted out.
It is the precise structure, compact, it is easy to operate, without in needle tubing insertion skin, not resulting in pollution, using it is more efficient,
Safety；Because decoction is spurted at a high speed subcutaneously, decoction disperse is easy to human body quickly to absorb in hypodermis, meanwhile, cause
Wound is tiny, and the pain caused is also extremely weak；There is larger improvement on user experience and degree easy to use, use simultaneously
Clean, health, does not result in germ contamination；User originally quantifies nothing using replaceable liquid storing tube after terminating so as to greatly prolong
The usage cycles of pin injection pen.
Preferably, the accumulator includes the pedestal for being fixed on handle inner, and the storage power disk on pedestal
Spring, one end of the storage power disc spring is fixedly connected with the pedestal, and the other end is fixedly connected with the inwall of rotating cylinder；The structure can
Driving force is stored when rotating cylinder rotates, and drives rotating cylinder high-speed reverse to rotate when user looses one's grip, and then promotes pushing block to extrude
Medicine, forms the decoction stream of injection at a high speed, and then it is subcutaneous that decoction is squeezed into human body.
Preferably, the pushing block is made with sealing block using permanent-magnet material, both opposite face heteropoles are attracting；In order to
Strengthen tight binding ability between pushing block and injection groove, be easy to being completely exhausted out for decoction.
Preferably, in the push side of the pushing block with offering the concavo-convex lines matched on the groove face of injection groove；Decoction
Flow into after medicine-storing cavity, the lines can produce flow-disturbing to decoction, and then promote the mixing of decoction, be easy to that decoction is uniform, stable enter
Enter human body, be easy to the absorption of human body.
