Abstract

The utility model discloses a kind of syringe and return cap device, including slotting cap plate, described slotting cap plate has multiple through hole, described through hole internal diameter is more than the internal diameter of the needle cap opening part boss of syringe, less than the external diameter of the needle cap opening part boss of syringe.During use, needle cap being positioned over syringe and returns on cap device, nurse returns cap device righting needle cap by syringe after having taken out medicine, and one hand carries out back cap, effectively prevents the generation of pricking wound.

Description

Syringe returns cap device

Technical field

This utility model is a kind of medical assistance apparatus, is specifically that a kind of syringe returns cap device.

Background technology

In the prior art, pricking wound is a kind of unexpected injury often occurred in hospital, especially for nurse, often connects Touching the sharp instruments such as syringe, the most easily cause pricking wound, almost there is pricking wound in every nurse.In order to prevent acupuncture The generation of wound, hospital formulary nurse forbids that both hands return cap.For the syringe needle polluted, nurse is not required to back cap and can directly be abandoned by syringe needle In sharp instrument box；And for clean syringe needle, owing to the most suitably returning cap device, in order to ensure the aseptic of syringe needle, nurse Usually carrying out both hands returns cap in violation of rules and regulations, although this ensure that the aseptic of syringe needle, but there is potential safety hazard, it is possible to cause pricking wound Generation.Although clean syringe needle is not result in the propagation of infectious disease, but can still result in that nurse is injured to bleed, carry to nurse Carry out unnecessary injury.

Utility model content

For above-mentioned shortcoming and defect of the prior art, the purpose of this utility model be to develop a kind of assist back cap and It can be avoided that the syringe of the needle sting human body of syringe returns cap device when returning cap.

The purpose of this utility model is achieved through the following technical solutions:

A kind of syringe returns cap device, including slotting cap plate, described slotting cap plate has multiple through hole, and described through hole internal diameter is big In the internal diameter of the needle cap opening part boss of syringe, less than the external diameter of the needle cap opening part boss of syringe.

Preferably, also include that support column and base, the upper end of described support column are fixedly connected on slotting cap plate lower surface, lower end Fix with the upper surface of described base and be connected.

Preferably, also having multiple through hole on described base, described through hole internal diameter is more than the needle cap opening part of syringe The internal diameter of boss, less than the external diameter of the needle cap opening part boss of syringe.

Preferably, described slotting cap plate is fixedly mounted on support column upper end by screw.

Preferably, described base through screws is fixedly mounted on the lower end of support column.

Preferably, described slotting cap plate is that duroplasts inserts cap plate.

Preferably, described support column is hard plastic support post, and described base is duroplasts base.

Preferably, the plectane that described slotting cap plate is the most identical with thickness with sized by base.

Preferably, the through hole internal diameter on described base is more than inserting the internal diameter of through hole on cap plate.

Compared with prior art, this utility model embodiment at least has the advantage that

During use, needle cap being positioned over syringe and returns on cap device, nurse returns cap device by syringe after having taken out medicine and holds up Positive needle cap, one hand carries out back cap, effectively prevents the generation of pricking wound.

Accompanying drawing explanation

Fig. 1 is the structural representation of injector needle cap；

Fig. 2 is the front view that this utility model syringe returns cap device；

Fig. 3 is the top view of Fig. 2.

Detailed description of the invention

Below in conjunction with Fig. 1-3 and embodiment, the utility model is described in further detail, and following example are illustrative, It not determinate, it is impossible to limit protection domain of the present utility model with this.

As Figure 1-3, Fig. 1 is the structural representation of injector needle cap, and Fig. 2 is that this utility model syringe returns cap device Front view, Fig. 3 is the top view of Fig. 2.

A kind of syringe returns cap device, including slotting cap plate 1, inserts and has multiple through hole 6 on cap plate 1, and through hole 6 internal diameter is more than note The internal diameter of the needle cap opening part boss 5 of emitter, less than the external diameter of the needle cap opening part boss 5 of syringe.

Also including support column 3 and base 2, the upper end of support column 3 is fixedly connected on slotting cap plate 1 lower surface, lower end and base 2 Upper surface fixing connect.

Also having multiple through hole 6 on base 2, through hole 6 internal diameter is more than the internal diameter of the needle cap opening part boss 5 of syringe, External diameter less than the needle cap opening part boss 5 of syringe.

Insert cap plate 1 and be fixedly mounted on support column 3 upper end by screw 4.

Base 2 is fixedly mounted on the lower end of support column 3 by screw 4.

Insert cap plate 1 and insert cap plate for duroplasts.

Support column 3 is hard plastic support post, and base 2 is duroplasts base.

Insert the plectane that cap plate 1 is the most identical with thickness with sized by base 2.

Through hole 6 internal diameter on base 2 is more than inserting the internal diameter of through hole 6 on cap plate 3.The syringe of corresponding different model, syringe needle Specification be also different, the size of corresponding needle cap is also different, according to the size of needle cap, selects base 2 one side Through hole 6 insert cap still insert cap plate 1 one side through hole 6 insert cap can be according to being actually needed selection.

As a kind of preferred embodiment, the internal diameter inserting the multiple through holes 6 on cap plate 1 and base 2 can also be the most not With, through hole 6 can be processed according to the needle cap of all specifications, the through hole 6 of various different inner diameters is respectively distributed to base 2 and slotting cap On plate 1, but select suitable through hole 6 to carry out inserting cap for convenience, the needle cap of correspondence can be shown in each through hole 6 side Specification.

During use, needle cap being positioned over syringe and returns on cap device, nurse returns cap device by syringe after having taken out medicine and holds up Positive needle cap, one hand carries out back cap.

The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should It is as the criterion with the protection domain of claims.
