Abstract

The utility model relates to a high-hydraulic scar syringe, which comprises a syringe and a booster connected with the tail end of the syringe, wherein, the booster comprises a sleeve barrel, a casing nut and an injection screw. One end of the sleeve barrel is provided with an external thread, a shaft center of the other end of the sleeve barrel is provided with a threaded hole in which the injection screw is screwed, the outer end of the injection screw is connected with a rotating disk, and a long hole along axial direction is arranged on the wall of the sleeve barrel. The inside diameter of a top hole of the casing nut is matched with the outside diameter of an outer sleeve of the syringe, an inner pipe thread of the casing nut is matched with an external pipe thread at one end of the sleeve barrel, a thread end of the casing nut is provided with two opposite notches, and two radial handles at the tail end of the outer sleeve of the syringe are clamped into the notches. The precession of the injection screw is used by the utility model for pushing an injection handle of the syringe, very large pressure can be generated to physic liquor injection, labor is saved, and physic liquor can be injected evenly and slowly. The utility model has the advantages of simple structure and practicality.

Description

High hydraulic pressure cicatrix syringe

Technical field

This utility model relates to medical instruments, and particularly a kind of high hydraulic pressure cicatrix syringe is mainly used in medicine injection treatment treatment keloid.

Background technology

The sickness rate of keloid is very high among China person between twenty and fifty, when drug application injection treatment treatment keloid, must be injected into medicine in the outgrowth cicatrix essence just effective.And keloid is to be formed by excessive outgrowth collagen fiber deposition, and is so it organizes particularly compact tightly tough, very difficult with the ordinary syringe injection.

Summary of the invention

The purpose of this utility model just provides a kind of easy to use, and injection is easy to high hydraulic pressure cicatrix syringe.

For achieving the above object, this utility model is taked following technical scheme: comprise syringe, also comprise the booster that is connected with described syringe tail end, this booster comprises: sleeve, sleeve nut, injection screw, at a telescopic end external screw thread is arranged, screw is arranged, screw in injection screw in it in other end axle center, connect a rotating disk in the outer end of this injection screw, slotted hole is vertically arranged on described sleeve wall; The apical pore internal diameter of sleeve nut cooperates with the external diameter of described syringe jacket, its Internal Pipe Thread cooperates with the external pipe thread of described sleeve one end, the end of thread at this sleeve nut has two relative breach, two of the syringe jacket tail end radially handle snap in this breach.

Also comprise and the inner push-plate that is connected of described injection screw.

This utility model utilizes the injection handle of injection screw precession pushing syringe, can produce very big pressure to liquid medicine injection, not only laborsaving but also can be evenly liquid medicine injection lentamente.It is simple in structure, practical.

The specific embodiment

Referring to Fig. 1-Fig. 5, this utility model comprises syringe 1, the booster that is connected with the tail end of described syringe 1, this booster comprises: sleeve 2, sleeve nut 3, injection screw 4, end at sleeve 2 has external screw thread 21, in the other end axle center screw 22 is arranged, and screws in injection screw 4 in it, connect a rotating disk 5 in the outer end of this injection screw 4, slotted hole 23 is vertically arranged on described sleeve 2; The internal diameter of the apical pore 31 of sleeve nut 3 cooperates with the external diameter of the overcoat 11 of described syringe 1, its Internal Pipe Thread 32 cooperates with the external pipe thread 21 of described sleeve 2 one ends, the end of thread at this sleeve nut 3 has two relative breach 33, two of syringe jacket 11 tail ends radially handle 12 snap in this breach 33.The inner at described injection screw 4 connects a push-plate 6.

When using this utility model, the sleeve nut 3 of booster front end is screwed off, the front end of having taken out the 5ml of medicinal liquid or 3ml syringe 1 end from sleeve nut 3 jagged 33 is passed, and two handles 12 of syringe jacket tail end are just in time snapped in the breach 33.Injection handle 13 with the syringe tail end inserts sleeve 2 again, and the external screw thread 21 of sleeve nut 3 with sleeve end screwed, and makes syringe jacket 11 and booster fastening.Make its inner push-plate 6 withstand the injection handle 13 of syringe 1 by rotating disk 5 rotary injection screw rods 4 then.Carried out the preparation of injection this moment.The rotating disk 5 of injection screw 4 outer ends of turning clockwise during injection gets final product.

Claims

1, a kind of high hydraulic pressure cicatrix syringe, comprise syringe, it is characterized in that: also comprise the booster that is connected with described syringe tail end, this booster comprises: sleeve, sleeve nut, injection screw, at a telescopic end external screw thread is arranged, screw is arranged, screw in injection screw in it in other end axle center, connect a rotating disk in the outer end of this injection screw, slotted hole is vertically arranged on described sleeve wall; The apical pore internal diameter of sleeve nut cooperates with the external diameter of described syringe jacket, its Internal Pipe Thread cooperates with the external pipe thread of described sleeve one end, the end of thread at this sleeve nut has two relative breach, two of the syringe jacket tail end radially handle snap in this breach.
