Abstract

Provided is a depth setting injector. A protruding surface (1) having the same length with a depth setting needle tube is arranged at the upper end of the depth setting needle tube, and a capacity dial gauge is arranged on the protruding surface (1). A depth setting sleeve (2) is sleeved on the depth setting needle tube, and the internal diameter and the length of the depth setting sleeve (2) are respectively identical to the external diameter and the length of the depth setting needle tube. A through opening (2-1) corresponding to the protruding surface (1) is arranged at the upper end of the depth setting sleeve (2) and has the same length with the protruding surface (1), and the width of the through opening (2-1) is slightly larger than that of the protruding surface (1). A plurality of prisms (2-2) which are arranged at the same interval and have the same length and width with the protruding surface (1) are arranged at edges on two sides of the through opening (2-1) and on the periphery of the depth setting sleeve (2). The depth setting injector can set the injection depth in advance and master the injection depth.

Description

Depthkeeping syringe

Technical field

The present invention relates to a kind of syringe that can set in advance and can control injection depth, i.e. depthkeeping syringe.

Background technology

While having an injection to patient, syringe needle penetrates the depth degree of muscle, be that injection depth directly has influence on the assimilation effect of medicine and patient's pain perception, cross dark or cross and shallowly all can bring harmful effect to patient, present widely used ordinary syringe, when use, its injection depth with operator's technical experience and the random control of sensation, is difficult to reach science requirement accurately entirely.

Summary of the invention

The present invention will provide a kind of depthkeeping syringe that can set in advance in use and can control injection depth, to make up the deficiency of ordinary syringe.

Technical scheme

A kind of depthkeeping syringe, comprise depthkeeping needle tubing, depthkeeping cover, pintle and syringe needle, it is characterized in that, there is a fan-like pattern projecting surface depthkeeping needle tubing outer wall upper end, on this projecting surface, be carved with containing mark table, its length flushes with depthkeeping needle tubing front and back end, and its width equates with the width of the containing mark table of common needle tubing.There is the depthkeeping cover of front and back to pass through openings one upper end, this depthkeeping cover is enclosed within on depthkeeping needle tubing outer wall, its internal diameter equates with depthkeeping needle tubing external diameter, opening is corresponding with the projecting surface of depthkeeping needle tubing, A/F is slightly larger than the width of projecting surface, the length of opening and projecting surface equal in length, and depthkeeping cover edge, opening both sides and periphery are provided with and multiplely equidistantly sagittally overlap isometric prism with depthkeeping, the thickness of prism equates with the thickness of projecting surface, and width can be large as much as possible.

Beneficial effect

1, while injection, can set and can control injection depth.

2, grasp simple and easy to operate, injection depth degree of accuracy is high.

Detailed description of the invention

Fig. 1, be depicted as depthkeeping needle tubing, pintle and needle head structure schematic diagram, there is a fan-like pattern projecting surface 1 depthkeeping needle tubing outer wall upper end, this projecting surface 1 flushes with depthkeeping needle tubing front and back end, on this projecting surface 1, be carved with containing mark table, the width of this projecting surface 1 equates with the containing mark table width of ordinary syringe, and pintle, syringe needle are identical with pintle, the syringe needle of ordinary syringe.

Fig. 2, for the depthkeeping of depthkeeping syringe overlaps 2 structural representations, internal diameter, the length of this depthkeeping cover 2 equate respectively with external diameter, the length of depthkeeping needle tubing, depthkeeping overlaps 2 upper ends has front and back corresponding with the projecting surface 1 of depthkeeping needle tubing to pass through openings 2-1, opening 2-1 width is slightly larger than the width of projecting surface 1, edge, this opening 2-1 both sides and depthkeeping overlap 2 peripheries and are provided with and multiplely overlap with depthkeeping the prism 2-2 that 2 front and back are isometric and interval equates, the thickness of multiple prism 2-2 equates with the thickness of projecting surface 1, in the scope of the circumference of depthkeeping cover 2, the desirable maximum of width.The material requirements of making depthkeeping cover has suitable consistency and elasticity, makes the depthkeeping cover 2 under normal circumstances can maintainance set shape shape, overlaps wall energy and produce certain bending while holding, and prism 2-2 has certain impact resistance.

Fig. 3, for using front depthkeeping cover 2 to be enclosed within on depthkeeping needle tubing, and depthkeeping overlaps the depthkeeping syringe construction schematic diagram of 2 front and back ends in the time that depthkeeping needle tubing front and back end flushes, containing mark table on depthkeeping needle tubing upper end projecting surface 1 appears clear, obviously, while using depthkeeping syringe to draw injection, there is nothing different from the using method of ordinary syringe.

Fig. 4, overlaps the depthkeeping syringe construction schematic diagram of 2 present positions for having set the depthkeeping of injection depth before injecting, before depthkeeping cover 2, postpone, and stretches the injection depth of overlapping needle length before 2 front ends and be setting at depthkeeping.

From Fig. 1,2,3,4, depthkeeping syringe is drawn after injection, before infer dark cover 2, set injection depth, holding cover has the depthkeeping needle tubing of depthkeeping cover 2 to inject, and due to the grip of hands, that depthkeeping cover 2 is combined with depthkeeping needle tubing is as a whole, and the touching of prism 2-2 front end end face and muscle can make syringe needle stop in the degree of depth of setting,, obtained the effect of setting and control injection depth.

Due to depthkeeping cover, there is opening 2-1 2 upper ends, therefore press and wait operation also without prejudice for pull out pin and cotton balls after injection.

The area that suitably increases prism 2-2 front end end face can reduce the impact pressure between front end end face and skin.

Depthkeeping cover 2 is used in conjunction with and also can obtains reasonable depthkeeping injection effect with ordinary syringe.
