Description
Technical field:
The present invention relates to the technical field of medical apparatus and instruments, more specifically to a kind of improved syringe of structure.
Background technology:
Syringe, generally primary production, become danger after the pathogen with use can be stained with medicine or patient later
Dangerous article, and the case that the apparatus due to surprisingly being carried syringe needle by these pierces is too numerous to enumerate, in order to avoid by such contaminated
Thorn part is stabbed or the therefore health risk infecting, some preventers existing in prior art, and existing preventer is general
For a simple needle cap, needle cap is sheathed on syringe needle, but such needle cap and needle set cooperation are inaccurate, and Hospitals at Present is
Avoid used syringe to flow out, be frequently used and directly the core bar of syringe fracture later, then medical personnel are fractureing
So that needle cap and syringe needle is departed from core bar or recovery personnel's removal process, be then easy for medical personnel or reclaim people
Member damages.
Content of the invention:
The purpose of the present invention is aiming at the deficiency of prior art, and provides a kind of improved syringe of structure, its increasing
Strong bonding strength between protective case and syringe, thus the state that protective case is departed from syringe can be reduced.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of improved syringe of structure, including syringe, the top of syringe forms the boss of cone, grafting on boss
It is fixed on injection needle, outside injection needle, is inserted with protective case, protective case is made up of conical base and cylindrical upper pipe box, bottom
The lower end of seat forms adapter sleeve straight down, the adapter sleeve sleeve of base on the boss of syringe, the syringe of outside the boss
Land is formed on top surface, the inwall of land forms several flanges, the outer wall of base upper joint sleeve forms with convex
The groove that edge matches, flange is plugged in the groove of base adapter sleeve, and the outer wall of adapter sleeve is resisted against on the inwall of land, phase
Rib is formed on the adapter sleeve outer wall between adjacent groove, the outer end of rib forms reinforcing sleeve, and reinforcing sleeve sleeve is in land
And be resisted against on the outer wall of land.
If arterial highway annular groove is formed on the outer wall of land on described syringe.
Groove on the adapter sleeve of described base is in circular arc, and groove ringwise uniformly divides around the central axis of adapter sleeve
Cloth, the groove number on adapter sleeve is identical with the flange number in land.
The inwall molding cone of described base upper joint sleeve, the angle of inclination of the inwall of adapter sleeve and syringe convex platform
Angle of inclination is equal.
The top of described upper pipe box forms vertical pole, and the top of pole forms handle.
The beneficial effects of the present invention is: its structure is simple, has rectified and improved the structure of protective case, increases protective case and syringe
The area of contact, thus increasing the bonding strength between it, thus the state that protective case is departed from syringe can be reduced, it is to avoid depart from
The injection needle of protective case damages to medical personnel or recovery personnel.

Specific embodiment:
Embodiment: as shown in Fig. 1 to 5, a kind of improved syringe of structure, including syringe 1, the top of syringe 1 forms
The boss 11 of cone, injection needle 3 is fixed in grafting on boss 11, is inserted with protective case 2, protective case 2 is by circular cone outside injection needle 3
The base 21 of shape and cylindrical upper pipe box 22 form, and the lower end of base 21 forms adapter sleeve straight down, base 21
Adapter sleeve sleeve, on the boss 11 of syringe 1, syringe 1 top surface in boss 11 outside forms land 12, the inwall of land 12
On form several flanges 121, the outer wall of base 21 upper joint sleeve is formed the groove 211 being matched with flange 121, convex
Edge 121 is plugged in the groove 211 of base 21 adapter sleeve, and the outer wall of adapter sleeve is resisted against on the inwall of land 12, adjacent grooves
Rib 212 is formed on the adapter sleeve outer wall between 211, the outer end of rib 212 forms reinforcing sleeve 213, reinforcing sleeve 213 sleeve
In land 12 and be resisted against land 12 outer wall on.
If forming arterial highway annular groove 122 or annular knurl on the outer wall of land 12 on described syringe 1.
Groove 211 on the adapter sleeve of described base 21 be in circular arc, groove 211 around adapter sleeve central axis ringwise
It is uniformly distributed, groove 211 number on adapter sleeve is identical with flange 121 number in land 12.
The inwall molding cone of described base 21 upper joint sleeve, the angle of inclination of the inwall of adapter sleeve and syringe 1 are convex
The angle of inclination of platform 11 is equal.
The top of described upper pipe box 22 forms vertical pole 23, and the top of pole 23 forms handle 24, upper pipe box
The fineness of 22 outer walls is preferable.
Operation principle: the present invention is the improved syringe of structure, specifically improves the protective case 2 on syringe, improves
Protective case 2 can strengthen the bonding strength and syringe between, thus not causing protective case 2 and syringe to depart from easily, and
Strengthen the mode of bonding strength, predominantly increase the contact surface between protective case 2 and syringe, such as boss 11 and base 21 lower end
Contact area between adapter sleeve (contact area between adapter sleeve outer wall and land 12 inwall, simultaneously adapter sleeve outer wall with
Corresponding groove 211 and flange 121 are formed on land 12, contact area can be increased), also land 12 outer wall and reinforcing sleeve
Contact area between 213 inwalls；Such that it is able to increase the frictional force of protective case 2 and syringe, prevent protective case 2 from pulling out easily
Go out, then in order to configuration protection set 2 departs from from syringe, be provided with pole 23 and handle 24, and by pole 23 when syringe is scrapped
Fracture, safer.
