Abstract
The utility model particularly relates to a needle head protective cap for a precharging type injector, which is characterized by comprising a needle head flexible cap and a needle head hard cap. Needle head holes are arranged on the needle head flexible cap, a projection is arranged on the outer surface of the needle head flexible cap, the shape of a cavity of the needle head hard cap matches with the shape of the needle head flexible cap, and a clamping slot matching with the projection of the needle head flexible cap is arranged on the inner surface of the needle head hard cap. The needle head protective cap for the precharging type injector solves the defects that needle head protective caps of precharging type injectors in the prior art can not give equal attention to two aspects of protecting needle head safety and guaranteeing needle head sealing performance, and the needle head protective cap for the precharging type injector has the advantages of simple structure, excellent sealing performance, safety, reliability and sanitation. The needle head flexible cap and the needle head hard cap are sleeved together, the needle head flexible cap and the needle head hard cap are fixed through the projection and the clamping slot, and the needle head protective cap gives equal attention to the safety and the sealing performance of the needle head.
Description
Technical field
This utility model is specifically related to a kind of precharging type syringe syringe needle helmet.
Background technology
In recent years, the frequent generation of public safety incidents such as SARS, bird flu, H1N1 is brought up to unprecedented height with people to the concern of vaccine; In addition, constantly perfect along with country disease prevention and control centers at different levels epidemic prevention system also has fast the demand of vaccine and to increase, and this all provides good fortune for the development of precharging type syringe.The precharging type syringe the inside is filled with a certain amount of medicinal liquid in advance, safety and sanitation, and extraneous antibacterial has only by syringe needle could pollute medicinal liquid, so the design of syringe needle helmet is particularly crucial.
The syringe needle helmet of prior art is divided into overseas cap and two kinds on hard medicated cap, and the overseas cap good airproof performance can prevent effectively that medicinal liquid from being polluted, but not enough to the protection of syringe needle; Hard medicated cap is better to the protection of syringe needle, but and between the syringe needle sealing poor, medicinal liquid is polluted easily.
The utility model content
The purpose of this utility model is to solve the syringe needle helmet of prior art precharging type syringe in the defective that can't get both aspect protection needle safety and the assurance syringe needle sealing two, and a kind of precharging type syringe syringe needle helmet that can take into account needle safety and syringe needle sealing is provided.
This utility model is achieved through the following technical solutions:
It is a kind of precharging type syringe syringe needle helmet, it is characterized in that comprising the syringe needle overseas cap and the hard medicated cap of syringe needle that are sleeved on together, described syringe needle overseas cap is provided with and the syringe needle hole, the outer surface of syringe needle overseas cap is provided with projection, the form fit of the cavity of the hard medicated cap of syringe needle and syringe needle overseas cap, the inner surface of the hard medicated cap of syringe needle are provided with the draw-in groove that mates with the projection of syringe needle overseas cap.
The projection of syringe needle overseas cap outer surface is positioned at the bottom of syringe needle overseas cap, and the draw-in groove of the hard medicated cap inner surface of syringe needle is positioned at the bottom of the hard medicated cap of syringe needle, with the projection coupling of syringe needle overseas cap.
The utlity model has simple in structure, good airproof performance, safe and reliable, hygienic advantages.This utility model is fitted together syringe needle overseas cap and the hard cap sleeve of syringe needle, between by the projection and draw-in groove fix, taken into account the safety and the sealing of syringe needle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the street corner sketch map of the hard medicated cap of syringe needle of the present utility model;
Fig. 3 is the structural representation of syringe needle overseas cap of the present utility model.
As shown in FIG.: the hard medicated cap of 1 syringe needle; 2 syringe needle overseas caps; 3 draw-in grooves; 4 syringe needle holes; 5 projectioies.
The specific embodiment
Below in conjunction with accompanying drawing embodiment is done detailed description:
As Fig. 1, Fig. 2, shown in Figure 3: syringe needle overseas cap 2 is sleeved in the hard medicated cap 1 of syringe needle, and the bottom of the outer surface of syringe needle overseas cap 2 is provided with projection 5, and the bottom of the inner surface of the hard medicated cap 1 of syringe needle is provided with draw-in groove 3.
When this utility model uses, syringe needle overseas cap 2 is sleeved in the hard medicated cap 1 of syringe needle, the projection 5 of syringe needle overseas cap 2 snaps in the draw-in groove 3 of the hard medicated cap 1 of syringe needle, and the syringe needle with precharging type syringe inserts syringe needle hole 4 interior getting final product again.
