Abstract

The utility model provides a technical program for scar gun type injector, consisting of a needle head, an injector, an injector piston, a push head connected with the injector piston and a push bar fixed with the push head. A demountable injector sub-panel fixed with an arm linked to a handle case is equipped on outer surface of the said injector. The said push bar through the upper part of the handle case is sheathed with a clutch spring, one end of which is arranged with a clutch snap gauge connected with the top of an injection trigger. The said injection trigger is located on a rotary shaft fixed on the handle case. Besides, the said push bar gets through a retainer located on the top of the handle case. In addition, a retarding spring is sheathed on the push bar between the handle case and the retainer. A recoil grip is positioned on the end corresponding to the push head on the said push bar.

Description

A kind of cicatrix gun-type syringe

Technical field:

The utility model relates to the syringe that a kind of injection medicament is used, especially a kind of cicatrix gun-type syringe.

Background technology:

In the prior art, technique known is to authorize disclosed No. 02240708.1 patent by State Intellectual Property Office, this patent disclosure a kind of cicatrix syringe, its scheme is at existing syringe needle, installed additional on syringe and the syringe piston and cut somebody's hair and push rod, push rod is then cut somebody's hair by screw mechanism, cut somebody's hair again the pushing syringe piston with drug injection in cicatrix, though this syringe can strengthen the pressure of injection, but when injection, adopt the injection speed of screw propulsion syringe piston too slow, this has just increased the time of injection, also just increased patient's misery, this is the existing in prior technology weak point.

Summary of the invention:

The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of technical scheme of cicatrix gun-type syringe, this scheme adopts the injection trigger to promote push rod, this not only can strengthen the pressure of injection, and can artificially control on demand the speed of injection, reduced the time of injection, also just reduced patient's misery.

This programme is realized by following technical measures: include syringe needle, syringe and syringe piston, contacted with syringe piston and to have cut somebody's hair, and be fixedly connected with push rod with cutting somebody's hair, the characteristics of this programme are that dismountable syringe installing plate is arranged on described syringe outer wall, the fixedly connected pole of this syringe installing plate, pole fixedlys connected with handle box again, described push rod just passes handle box top, be with the clutch spring on the push rod in handle box, one end of this clutch spring has the clutch clamp, and the clutch clamp is connected with the top of injection trigger, and described injection trigger is contained in the rotating shaft, and rotating shaft then is fixed on the handle box; Retaining plate also is housed on end face on the handle box, and described push rod also passes this retaining plate, also is with the retaining spring on the push rod between handle box and the retaining plate.The concrete characteristics of this programme also have, and the corresponding end of cutting somebody's hair on described push rod also has the return handle.

The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme dismountable syringe installing plate is arranged on the syringe outer wall, the then fixedly connected pole of syringe installing plate, pole fixedlys connected with handle box again, and push rod just passes handle box top, be with the clutch spring on the push rod in handle box, one end of this clutch spring has the clutch clamp, and the clutch clamp is connected with the top of injection trigger, described injection trigger is contained in the rotating shaft, and rotating shaft then is fixed on the handle box.Retaining plate also is housed on end face on the handle box, and described push rod also passes this retaining plate, also is with the retaining spring on the push rod between handle box and the retaining plate.This structure, just can promote push rod and move forward by pulling the injection trigger, push rod is then injected with regard to the pushing syringe piston, utilize the injection pressure of injection trigger pushing syringe piston, substantially exceed the injection pressure of staff pushing syringe piston, and, the control as required that injection speed again can be artificial, this has just reduced injects the required time, the corresponding misery that has also just reduced patient.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings:

Fig. 1 is the part sectional structure sketch map of this utility model specific embodiment.

Among the figure, 1 is pole, and 2 is the syringe installing plate, and 3 is syringe, and 4 is syringe needle, and 5 is syringe piston, 6 for cutting somebody's hair, and 7 is push rod, and 8 is handle box, and 9 are the clutch clamp, and 10 is retaining plate, 11 are the return handle, extractor till 12, and 13 are rotating shaft, and 14 are the clutch spring, and 15 are the injection trigger.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

By accompanying drawing as can be seen, the cicatrix gun-type syringe of this programme has syringe needle (4), syringe (3) and syringe piston (5), has contacted cut somebody's hair (6) with syringe piston (5), and has been fixedly connected with push rod (7) with cut somebody's hair (6).This programme is on described syringe (3) outer wall dismountable syringe installing plate (2) to be arranged, this fixedly connected pole of syringe installing plate (2) (1), pole (1) fixedlys connected with handle box (8) again, described push rod (7) just passes handle box (8) top, be with clutch spring (14) on the push rod (7) in handle box (8), one end of this clutch spring (14) has clutch clamp (9), and clutch clamp (9) is connected with the top of injection trigger (15), described injection trigger (15) is contained in the rotating shaft (13), and rotating shaft (13) then is fixed on the handle box (8).Retaining plate (10) also is housed on the last end face of handle box (8), and described push rod (7) also passes this retaining plate (10), also is with retaining spring (12) on the push rod (7) between handle box (8) and the retaining plate (10).The corresponding end of (6) of cutting somebody's hair on described push rod (7) also has return handle (11).
