Abstract
The utility model discloses a kind of safe injection needle; comprise injection needle, injection needle protective sleeve, elastic protecting sleeve; described injection needle is arranged on elastic protecting sleeve inside; and injection needle base is fixed on an end of elastic protecting sleeve; the other end of described elastic protecting sleeve is provided with bayonet ring, aperture bayonet ring being provided with injection needle through hole and being connected with injection needle base.Prick people when this utility model can prevent injection needle from not using, can avoid unnecessary wearing and tearing again, can prevent the Spreading and diffusion of pathogenic bacteria, in garbage processing procedure, avoid the probability of pricking people, most importantly production cost is low, very easily promotes the use of.
Description
Technical field
This utility model relates to area of medical devices, is specifically related to a kind of safe injection needle.
Background technology
Entry needle in the market; when every-day medical injection work; when injection needle does not completely newly use; without any safety guard; such syringe needle easily stabs related personnel; and easily wear and tear; especially after syringe needle is finished using; medical and nursing work personnel often abandon in refuse receptacle conveniently, carry a large amount of pathogenic bacterias in syringe needle, easily diffuse in crowd; very large threat is had to public safety health; and likely cause secondary to stab, and on market, existing safe injection needle manufacturing cost is very high, not easily promotes.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of safe injection needle.
To achieve these goals; this utility model solves the technical scheme that its technical problem adopts: a kind of safe injection needle; comprise injection needle, injection needle protective sleeve, elastic protecting sleeve; described injection needle is arranged on elastic protecting sleeve inside; and injection needle base is fixed on an end of elastic protecting sleeve; the other end of described elastic protecting sleeve is provided with bayonet ring, aperture bayonet ring being provided with injection needle through hole and being connected with injection needle base.
Furtherly; on the two sides of described elastic protecting sleeve, symmetry offers strip hole; the two ends of described strip hole are circular arc; on the edge, middle part of strip hole, symmetry offers semi arch breach, and described bayonet ring and injection needle base are all be connected in the opening sleeve of end setting of elastic protecting sleeve.
Furtherly, described injection needle protective sleeve is socketed on injection needle, and the length of injection needle protective sleeve is greater than the length of injection needle, and described injection needle through-hole aperture is greater than the external diameter of protective sleeve of syringe needle.
The beneficial effects of the utility model: prick people when this utility model can prevent injection needle from not using, unnecessary wearing and tearing can be avoided again, the Spreading and diffusion of pathogenic bacteria can be prevented, in garbage processing procedure, avoid the probability of pricking people, most importantly production cost is low, very easily promotes the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 is this utility model using state;
Fig. 3,4 is the structural representation of this utility model specific embodiment two.
Detailed description of the invention
Detailed description of the invention of the present utility model is set forth further below in conjunction with specific embodiment.
Embodiment one; a kind of safe injection needle as depicted in figs. 1 and 2; comprise injection needle 1, injection needle protective sleeve 2, elastic protecting sleeve 3; it is inner that described injection needle 1 is arranged on elastic protecting sleeve 3; and injection needle base 5 is fixed on an end of elastic protecting sleeve 3; the other end of described elastic protecting sleeve 3 is provided with bayonet ring 4, aperture bayonet ring 4 being provided with injection needle through hole and being connected with injection needle base 5.
Preferably; on the two sides of described elastic protecting sleeve 3, symmetry offers strip hole 6; the two ends of described strip hole 6 are circular arc; on the edge, middle part of strip hole 6, symmetry offers semi arch breach, and described bayonet ring 4 and injection needle base 5 are all be connected in the opening sleeve of end setting of elastic protecting sleeve 3.
Preferably, described injection needle protective sleeve 2 is socketed on injection needle 1, and the length of injection needle protective sleeve 2 is greater than the length of injection needle 1, and described injection needle through-hole aperture is greater than the external diameter of protective sleeve of syringe needle 2.
Embodiment two; a kind of safe injection needle as shown in Figure 3 and Figure 4; comprise injection needle 1, injection needle protective sleeve 2, elastic protecting sleeve 3; it is inner that described injection needle 1 is arranged on elastic protecting sleeve 3; elastic protecting sleeve 3 is that (sheath in Fig. 3 is deployed condition for folding or flexible telescopic sheath; sheath in Fig. 4 is folding or contraction state); the installation sleeve 7 of bayonet ring 4 and injection needle base 5 is fixedly connected with respectively, the bayonet socket clamping of injection needle base 5 and bayonet ring 4 or be separated at the two ends of sheath.
Preferably, above-mentioned bayonet ring 4 is integral type structure with installation sleeve 7 and elastic protecting sleeve 3, time processing molding.
When medical personnel use, drop-down elastomer protective sleeve 3, is blocked by needle mount 5 when elastomer protective sleeve 3 is pulled down to needle mount 5, and injection needle protective sleeve 3 will from injection needle 1 through hole Automatic-falling; When medical personnel finish using, elastomer protective sleeve 3 is retracted original shape, at this moment injection needle 1 is with regard in indentation elastomer protective sleeve 3, avoids in garbage collection procedure and causes secondary injury to people.
Simple change and the replacement of one of ordinary skilled in the art are all within protection domain of the present utility model.
