Including syringe needle, barrel and push rod, the front end of barrel is formed with the injection orifice and the rear end is opened, the front end of push rod inserts in the barrel, stretch out from barrel section of thick bamboo intracavity backward the rear end of push rod, the syringe needle is connected with the injection orifice of barrel, the fixed first sleeve pipe of cover on the syringe needle that be equipped with on the syringe needle, be equipped with on the first sleeve pipe with the different second sleeve pipe in sheath opening footpath, the activity of second sleeve pipe is cup jointed on first sleeve pipe, first sheathed tube front end is equipped with locking screw. The utility model discloses the length that can self -defined syringe needle spills can show the pressure value the when liquid medicine impels in real time, and it pinpoints position of infusion and can avoid too big misery and the body bulk damage who causes patient of medicine hydraulic pressure force.
Description
Technical field
This utility model belongs to a kind of medical instrument, specifically, particularly relates to a kind of syringe.
Background technology
Spasticity is one group shows as the general name of jerking movements obstacle and abnormal posture disease.It occurs and upper motion
The suppression of spinal cord downward movement path is weakened or interrupts and motor neuron is overexcited relevant by neuron.Cerebral palsy, cranium brain
Wound, spinal cord injury, tumor, cerebral infarction, neurological sexual dysfunction, metabolism disorder etc. all may result in spasticity.A type meat
Toxin is widely used the most clinically, is a kind of remedy,topical thing, can act on body peripheral motor teleneuron-neuromuscular junction
Place, causes muscular paralysis, link muscle spasm by retardance presynaptic membrane release acetylcholine.By injecting to tissue
Injection BOTOX effectively treat spasm, the injection of current BOTOX often with operator feel operate,
Some needs to be accurately positioned injection depth position, and some needs control to need Artificial Control drug flux pressure, control to get up non-
Often difficulty, flow is the most unstable, and undulatory property is the biggest, it is easy to make patient produce untoward reaction.
Utility model content
This utility model purpose is to provide a kind of syringe, to overcome syringe nothing during injection of prior art
Method is accurately positioned the defect inserting the syringe needle degree of depth.
This utility model realizes by the following technical solutions: a kind of syringe, including syringe needle, cylinder and push rod, institute
The front end stating cylinder is formed with injection orifice and rear end open, and the front end of described push rod is inserted in described cylinder, described push rod
Rear end is stretched out backward from cylinder into the barrel chamber, and described syringe needle is connected with the injection orifice of cylinder, described syringe needle is fixed with and is enclosed within pin
First sleeve on head, described first sleeve is provided with second sleeve pipe different from first sleeve bore, and described second sleeve pipe is lived
Moving and be socketed in first sleeve, the front end of described first sleeve is provided with lock-screw.
Described second sleeve pipe is provided with scale.
The front end of described push rod is provided with pressure transducer, described cylinder be provided with the processor being connected with pressure transducer and
Display unit.
The total length of described first sleeve and the second sleeve pipe is no longer than the length of syringe needle.
Compared with prior art, the beneficial effects of the utility model are: (1) this utility model can spill with self-defined syringe needle
Length, to facilitate doctor accurately to determine the degree of depth of acupuncture treatment, be accurately positioned the position of transfusion；(2) this utility model can be real-time
Force value when display medicinal liquid advances, doctor conveniently grasps the speed pushed pin, and effectively prevent that medicinal liquid pressure is excessive to be made patient
The misery become and somatic damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, syringe needle；2, the second sleeve pipe；3, lock-screw；4, first sleeve；5, cylinder；6, pressure transducer；7, push away
Bar.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of syringe, including syringe needle 1, cylinder 5 and push rod 7, the front end of described cylinder 5 is formed with injection
Hole and rear end open, the front end of described push rod 7 is inserted in described cylinder 5, the rear end of described push rod 7 in cylinder 5 barrel chamber to
After stretch out, described syringe needle 1 is connected with the injection orifice of cylinder 5, and described syringe needle 1 is fixed with the first sleeve being enclosed within syringe needle 1
4, described first sleeve 4 is provided with second sleeve pipe 2 different from first sleeve 4 bore, and described second sleeve pipe 2 is actively socketed on
On sleeve 4, the front end of described first sleeve 4 is provided with lock-screw 3, positions, by flexible second sleeve pipe 2, the tool that syringe needle 1 exposes
Body length, and fix with lock-screw 3.
Preferably, described second sleeve pipe 2 is provided with scale, positions, by scale, the concrete length that the second sleeve pipe 2 stretches out, and
The concrete length that location syringe needle 1 exposes further, and fix with lock-screw 3.
Preferably, the total length of described first sleeve 4 and the second sleeve pipe 2 is no longer than the length of syringe needle 1, to guarantee syringe needle 1
Can remain and expose.
Preferably, the front end of described push rod 7 is provided with pressure inductor 6, and described cylinder 5 is provided with pressure inductor 6 even
The processor connect and display unit, pressure transducer 6 gathers the pressure of medicinal liquid and feeds back to processor, and signal is converted by processor
Become pressure value show on the display unit, doctor can Real Time Observation transfusion pressure and regulate push rod 7 propelling speed, it is to avoid
The excessive misery that patient is caused of medicinal liquid pressure and somatic damage.
