Abstract

The utility model relates to a needle cover, solving the problem that a needle cover can be sheathed on a needle safely. Safety cover for needle of infusion comprises a needle cover and a hand hold connecting rod. The utility model is characterized in that the hand hold connecting rod is connected with the needle cover, and the utility model can be widely used for syringes.

Description

Syringe needle is recovered safety head

This utility model relates to a kind ofly can protect medical personnel when recovering syringe and needle guard, by the needle point thorn and syringe needle do not recover safety head.

Existing syringe is after having played pin, recover the needle cover period of the day from 11 p.m. to 1 a.m, can stab oneself finger, diseases such as easy infection hepatitis, its main cause is to recover and has shortcoming on the needle cover structure, as shown in Figure 1, must hold with finger, the opening of needle cover is aimed at needle point, otherwise Yi Ci and finger and cause infection also can not be exempted this danger fully even add the opening of large needle lid.

The purpose of this utility model is recovered safety head with regard to providing a kind of syringe needle of above-mentioned shortcoming of avoiding.

The purpose of this utility model is achieved in that syringe needle recovers safety head, comprises a needle cover and holds connecting rod on the other hand, it is characterized in that: hand-heldly hold connecting rod and be connected with needle cover.

Above-mentioned design when recovering needle cover, is held connecting rod needle cover is recovered syringe needle with hand-held, needn't be pointing direct gripping needle cover, and connecting rod is amesiality, so can avoid needle point to stab the danger of finger fully, obtains positive design effect.

Be described further by drawings and Examples more below.

Fig. 1 is for existing needle cover and recover the action sketch map;

Fig. 2 is for this utility model embodiment and recover the action schematic perspective view;

Fig. 3 is this utility model embodiment user mode action schematic perspective view;

Fig. 4 is this utility model embodiment jagged edge action schematic perspective view;

Fig. 5 is this utility model embodiment outward appearance action schematic perspective view;

Fig. 6 is Fig. 5 side view.

As shown in Figure 1: the ora terminalis 40 of exerting all one's strength that catches on syringe 4 is arranged at syringe 4 bottoms, and needle point 30 is arranged on the needle tubing 3.Illustrate its recover the action dangerous property.

Shown in Fig. 2,3,4: needle cover 2 is connected with hands and grips connecting rod 1.The opening 20 of needle cover 2 is big slightly horn-like, and is provided with jagged edge 21.Connecting rod 1 contains triangular-arc 10, and the outside, lower end is provided with the hand-held sheet 12 of holding, and side is provided with fixedly back-off 11 in addition.Recovering action represents as A1, A2, B and C among Fig. 2,4.Fixedly back-off 11 can catch on the ora terminalis 40 of exerting all one's strength of syringe 4, unlikely skidding off after needle cover is recovered.

As shown in Figure 3: after recovering, the design of triangular-arc 10 can with the driving fits fully of syringe 4 periphery, isolate extraneous.

As shown in Figure 4: when failing to aim at opening 20 as if needle tubing 3, needle point 30 is stuck in jagged edge 21, as long as syringe 4 is moved toward the C direction, can not be partial to by left and right sidesing shifting, when needle point 30 centrage 31 positions of rebounding, again with syringe 4 toward B direction shift-ins, just can recover safely and reach safe and reliable, the function of none error.

Claims
