Abstract

The invention discloses a kind of safety shield for medical needles, including shell body and inner housing, the inner housing is eccentric with the shell body to be socketed, the shell body can be rotated relative to the inner housing, the inner housing head end is provided with the first opening passed through for medical needle needle tubing, the inner casing can be moved axially with respect to medical needle needle tubing, the inner housing end and the shell body end are respectively equipped with the second opening and the 3rd opening passed through for medical needle syringe needle, second opening is located at the inner housing distal center position, the position at center is partial to positioned at the shell body in 3rd opening.Bending of needlepoint by pressure can destroy syringe needle by protector of the invention with this, simultaneously because the protection needle point of housing tail end and clip also will not it is exposed outside, it is to avoid people is damaged.

Description

A kind of safety shield for medical needles

Technical field

The present invention relates to a kind of safety shield for medical needles, belong to technical field of medical instruments.

Background technology

Medical needle, such as hypodermic needle, biopsy needle, intravenous inducting device, trocar, seal wire, pneumothorax puncture needle, these make Turn into dangerous goods after the pathogen that can be stained with medicine or patient after, and because accident is by these devices with syringe needle The case that tool is pierced is too numerous to enumerate, existing in order to avoid the health risk stabbed or therefore infected by such contaminated thorn part Existing some protectors in technology, but existing some protectors are protected and not in place, often it is also possible to suffering two Secondary injury.

Furthermore, existing various medical needles are disposable, are soon abandoned using simply putting pin after complete and emitting, due to Pin is emitted and insecure, and also the staff that process these medical wastes can be damaged, or even some lawless persons return again These medical needles abandoned are received, potential safety hazard is bigger, prior art does not find more thoroughly preventing for such case also Protection unit, syringe needle that will be after use is thoroughly damaged, and can not only avoid stabbing the recycling that can also prevent person who is ambitious or tenacious of purpose.

The content of the invention

The technical problem to be solved in the present invention is to provide a kind of safety shield for medical needles.

To solve the above problems, the technical solution adopted by the present invention is：

A kind of safety shield for medical needles, including shell body and inner housing, the inner housing are eccentric with the shell body Socket, the shell body can be rotated relative to the inner housing, and the inner housing head end is provided with first passed through for medical needle needle tubing Opening, the inner casing can be moved axially with respect to medical needle needle tubing, and the inner housing end and the shell body end set respectively There are the second opening and the 3rd opening passed through for medical needle syringe needle, second opening is located at inner housing distal center position Put, the 3rd opening is partial to the position at center positioned at the shell body.

Preferably, the shell body inner surface is provided with internal thread, and the inner casing external surface is provided with and the internal thread phase The external screw thread of adaptation.

Preferably, the shell body end inner side is provided with loading layers, has filler in the loading layers.

Preferably, the shell body and the inner housing are cylindrical shape housing.

Preferably, the loading layers inner stuffing is viscous silica gel.

Preferably, second opening and the described 3rd opening are equal-sized circular open.

The beneficial effect that the present invention is reached：

Protector of the invention can be used preceding or use rear enclosure in medical needle head in medical needle, preferably using preceding Put, it is safer.After putting, syringe needle can sequentially pass through the second opening, the 3rd opening and stretch out, it is to be used it is complete after, first basis The distance of regulation inner housing and medical needle head is needed, and then regulation shell body makes needle point as far as possible with the relative position of inner housing Contacted with shell body end, then outside rotational shell body（I.e. to the direction for increasing shell body and inner housing overall length）, make needle point Avoid the 3rd opening relative with shell body end other parts, last inwardly rotational shell body（I.e. to reduction shell body and inner casing The direction of body overall length）, and by bending of needlepoint by pressure during turning；

Filler in the loading layers of shell body end can also block needle point, so both prevent residue in needle tubing Leak, also thoroughly damage needle point, it is to avoid stab people and be recovered.Even if pole in particular cases the protector from medical needle Come off, needle point will not also cause harm.

Brief description of the drawings

Fig. 1 is the structural scheme of mechanism after medical needle and protector assembling in embodiment；

Fig. 2 is the structural representation of protector in Fig. 1；

Fig. 3 is the structure of casing ends in Fig. 1 to be intended to.

Specific embodiment

The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention Technical scheme, and can not be limited the scope of the invention with this.

As Figure 1-3, a kind of safety shield for medical needles, including shell body 2 and inner housing 1, inner housing 1 and shell The eccentric socket of body 2, shell body 2 can be rotated relative to inner housing 1, and the head end of inner housing 1 is provided with first to be opened for what medical needle needle tubing passed through Mouth 3, inner casing can be moved axially with respect to medical needle needle tubing, and the end of inner housing 1 and the end of shell body 2 are respectively equipped with for medical needle pin The second opening 4 and the 3rd opening 5 that head passes through, the second opening 4 are located at the distal center position of inner housing 1, and the 3rd opening 5 is located at outer Housing 2 is partial to the position at center.

Specifically, the inner surface of shell body 2 is provided with internal thread, and the outer surface of inner housing 1 is provided with adaptable with the internal thread External screw thread.

This syringe needle for being designed to be applicable different length of shell body 2 and inner housing 1, it is simple and convenient.

Further, the end of shell body 2 inner side is provided with loading layers, has filler in loading layers, the loading layers inner stuffing It is viscous silica gel, viscous silica gel referred to herein is that with sticking silica gel, filler in the end loading layers of shell body 2 can be with Needle point is blocked, leaking for residue in needle tubing had so both been prevented, needle point is also thoroughly damaged, it is to avoid stab people and be recovered. Even if in particular cases the protector comes off from medical needle for pole, needle point will not also cause harm.

Further, shell body 2 and inner housing 1 are cylindrical shape housing, and the second opening 4 and the 3rd opening 5 are big Small equal circular open.

The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, on the premise of the technology of the present invention principle is not departed from, some improvement and deformation can also be made, these improve and deform Also should be regarded as protection scope of the present invention.
