A kind of injection syringe for anaesthesia
Technical field
The present invention relates to the field of medical instrument technology, are specially a kind of injection syringe for anaesthesia.
Background technology
Syringe is usually made of the foraminate syringe of front end band and matching piston core pin, is extracted in core bar
When liquid either gas from syringe front end aperture suck when core bar be pushed by liquid or gas extrusion, existing injection
Device is all that artificial directly hold is fixed, and is then inserted directly into human body and is injected, and the process of injection is also to be fixed by artificial,
As Chinese patent discloses a kind of " anesthesia syringe " (Authorization Notice No.:202128764 U of CN), which includes injection tube
Piston rod with the syringe needle for being arranged on injection tube top and for promoting parenteral solution, injection tube is by interior injection tube and outer injection tube
Composition, is provided with coolant between interior injection tube and outer injection tube, the mode that piston rod is slidably connected with interior injection tube inner wall reaches
The running of syringe is arrived, the shortcomings that above-mentioned patent is:During use built on the sand, layman is unable to normal use, exhaust side
Face is pretty troublesome, and causes syringe built on the sand using error is also inevitably present with even if professional, easily generates medical treatment
Accident, and when using exhaust, it is easy to the waste of liquid medicine is generated, and can not determine when in use and syringe needle is controlled to be inserted into
Depth, when being inserted into too deep patient is easily made to feel violent pain, expected effect is not achieved when excessively shallow again.

The more firm effect of fixing device 14 has been arrived, fixing device 14 has been enable to be simply fixed on the body of patient very much, Er Qieduo
A fixed frame 149 is fixed simultaneously, makes fixing device 14 more firm.
Operation principle:When using injection syringe for anaesthesia, liquid medicine is sucked in injection-tube 1 by syringe needle 3, determines to need to insert
Enter the depth of syringe needle 3, pull draw ring 142 and stay column 143, fixed tooth 145 is made to be separated with the locating slot on graduated scale disk 2, then
Fixing device 14 is socketed on injection-tube 1, and unclamps draw ring 142, fixed tooth 145 is connected together with locating slot, it will be solid
Determine device 14 to be fixed on injection-tube 1, viewing graduated scale disk 2, using draw ring 142, by fixing device 14 on graduated scale disk 2
Distance is adjusted, and the length that syringe needle exposes and the depth being inserted into are equal with the distance on graduated scale disk 2, determine to reach requirement
Afterwards, second handle 12 is pushed into, air-pressure chamber 10 is pushed by the second push rod 11 into injection-tube 1, and air-pressure chamber 10 will be in injection-tube 1
Gas extrusion is discharged, and after ready, syringe needle 3 is inserted into patient affected part, when syringe needle 3 is inserted into, fixed frame 149 can be by injection-tube 1
It is fixed on the body of patient, prevents injection-tube 1 from rocking, promote the first push rod 6 that liquid medicine is squeezed into patient's body, it is whole so as to complete
A work.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
