Description

A kind of single hand operated syringe

Technical field

This utility model belongs to surgery article, is specifically related to a kind of single hand operated syringe.

Background technology

Conventional syringe generally all wants both hands to use, and the time standby used is pointed and is carried out push-and-pull and injection, often firmly uneven, cause syringe needle to fracture or bend, also having some patients due to comparatively far away apart from hospital outpatient, and handicapped, therefore often drug injection to be carried out to oneself, use traditional syringe, operation is inconvenience very, brings great trouble to patient.

Utility model content

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of single hand operated syringe, this injection device, can use by very simple single-hand held, and has an effect when push-and-pull evenly.

The technical solution adopted in the utility model is: comprising: syringe, hold shank type push-and-pull piston, syringe needle, described syringe comprises body, slide rail, mill stricture of vagina tube wall, block, syringe needle hole, described shank type push-and-pull piston of holding comprises hands and holds handle, push-pull bar, piston, chute, described holds shank type push-and-pull piston, push-pull bar and piston are in syringe, hands holds handle outside syringe, slide rail on tube wall be embedded in hands hold handle under chute in, described mill stricture of vagina tube wall be positioned at the side of body and slide rail symmetrical, described block is positioned at the side of mill stricture of vagina tube wall, the afterbody of syringe, described syringe needle hole is positioned at the head of syringe.

Further, described slide rail is I-shaped directive slide track.

Further, described puttee is rectangle, uses cotton spinning or fibrous material to make.

Further, described hands holds handle and push-pull bar, and I is integrally connected, and it is curved surface circular shape that hands holds handle inner surface, and has described chute, and outer surface is concaveconvex shape of shaking hands, and does the process of mill stricture of vagina, and hands holds the syringe surface that handle size can cover 1/3.

The beneficial effects of the utility model:

A kind of single hand operated syringe that this utility model provides, this single hand operated syringe body side has the hands that can slide up and down along syringe and holds handle, hands is held handle and is connected with the push-pull bar piston in syringe, drive push-pull bar piston to move up and down and realize injection or draw medicine, syringe tube wall is mill stricture of vagina tube wall, hands holds handle also through having gone the process of mill stricture of vagina, increase frictional force, medical personnel or patient can hold syringe and complete medicament extraction to injection by singlehanded hands, facilitate the use of people greatly, particularly because a variety of causes needs the sufferer of oneself injection.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described further.

See Fig. 1 and Fig. 2, it is a kind of single hand operated syringe structural representation that the utility model proposes.

As shown in Figure 1, a kind of single hand operated syringe, comprise syringe (1), hold shank type push-and-pull piston (2), syringe needle (3), described syringe (1) comprises body (11), slide rail (12), mill stricture of vagina tube wall (13), block (14), syringe needle hole (15), described shank type push-and-pull piston (2) of holding comprises hands and holds handle (21), push-pull bar (22), piston (23), chute (24), described holds shank type push-and-pull piston (2), wherein push-pull bar (22) and piston (23) are in syringe (1), hands holds handle (21) at syringe (1) outward, slide rail (12) on tube wall be embedded in hands hold handle (21) under chute (24) in, described mill stricture of vagina tube wall (13) be positioned at the side of body (11) and slide rail (12) symmetrical, described block (14) is positioned at the side of mill stricture of vagina tube wall (13), the afterbody of syringe (1), described syringe needle hole (15) is positioned at the head of syringe (1).

Further, described mill stricture of vagina tube wall (13) is circular arc camber shape, covers syringe (1) tube wall of 1/3.

Further, described slide rail (12) is I-shaped directive slide track.

Further, described hands holds handle (21) and push-pull bar (22), and I is integrally connected, it is curved surface circular shape that hands holds handle (21) inner surface, and have described chute (24), outer surface is concaveconvex shape of shaking hands, and do the process of mill stricture of vagina, hands holds syringe (1) surface that handle (21) size can cover 1/3.

In the present embodiment, described syringe (1) tube wall, one side is mill stricture of vagina tube wall (13) increasing friction force, one side is directive slide track (12), hands is held after handle (21) is inlaid into, hands is held handle (21) and just can be moved up and down along this directive slide track (12), final realization and hands hold push-pull bar (22) piston (23) the moving up and down in body (11) that handle one is connected, complete medicament extraction and injection, hands is held handle (21) surface and is also done the process of mill stricture of vagina, skid when avoiding user to use, and hands is held handle (21) and has been ergonomic designs according to the shape that human body is held, the more convenient people of curved surface grasp use.

By reference to the accompanying drawings this utility model preferred implementation is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from this utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that this utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
