Description

Safety cover for butterfly needle

This utility model relates to a kind of butterfly needle safety needle cover, particularly at using the butterfly pin syringe needle that has been polluted, for avoiding needle sting medical personnel or other third parties, and the butterfly needle safety needle cover to innovate, the syringe needle of stopping to have been polluted is stabbed the danger of infection once again, and improves the safe and practical property of butterfly pin.

The use of general traditional butterfly pin is: with reference to Fig. 1, the protection needle guard 14 of butterfly pin 10 front ends is taken off, make syringe needle 11 thrust human body and inject, to be injected finishing after syringe needle 11 extractions, syringe needle 11 has been polluted, then must syringe needle 11 be reinstalled in the former protection needle guard 14 carefully; Because general butterfly pin 10 is to be used in a drop bottle injection, and need inject time through a few hours, therebetween or syringe needle displacement is arranged, skid off blood vessel and make by the injector and do not feel well, need extract syringe needle 11 midway injects again and injects and pull out program of pin etc. after finishing, polluted through injection because of syringe needle again, when extracting human body, must recover former protection needle guard 14, and former injector perhaps is not same people with the person that pulls out the pin, increases and be stranded for seeking former protection needle guard 14; Moreover protection needle guard 14 is the tiny pipe box of internal diameter, and the finger of holding former needle guard, collides in recovering process or because of tired, busy, luminance shortage certainly in the place ahead that suffers contaminated pinhead, and the probability of holding former needle guard finger in the thorn is high.

This creator feels high risk (as: AIDS, hepatitis B, violent sudden and violent hepatitis, the syphilis of blood-borne disease deeply ... Deng), and take medical personnel's life security into account, so a kind of butterfly needle safety needle cover is provided, the syringe needle that can stop fully to have been polluted is stabbed infection once again, more increases the rapid safety protection structure of butterfly pin.

The purpose of this utility model is to provide a kind of butterfly needle safety needle cover, especially at using the syringe needle that has been polluted, can quickly and effectively syringe needle be reclaimed and be equipped in the safe needle guard raising safety, practicality.

The purpose of this utility model reaches as follows:

A kind of butterfly needle safety needle cover, this safe needle guard is hollow cylindrical, it is characterized in that: the line of rabbet joint is offered in its upper end, this line of rabbet joint front end is the V-shape and the introducing port of circular arc slightly, a thin straight trough seam is offered in the stage casing, and end is offered an elongated rectangular clamping slot, and this clamping slot front end is established two chamfer bevels, the butterfly pin is set in the safe needle guard, and the fin of butterfly pin supports to arrive in the clamping slot that is fixed in safe needle guard.

The purpose of this utility model can also following mode reach: described butterfly needle safety needle cover is characterized in that: left and right two sides of this safe needle guard respectively offer a described line of rabbet joint.

The syringe needle that effect of the present utility model has been polluted after mainly can preventing to inject comes off and skids off, and in when recovering syringe needle, make medical personnel's both hands all be positioned at the syringe needle rear, can prevent the danger that medical personnel's both hands are caught by needle sting, the security protection effect to the butterfly pin is provided.

This utility model will reach graphic in conjunction with the embodiments, and it is as follows to describe structure of the present utility model, purpose and special efficacy in detail:

Among the figure:

Fig. 1 is the structural representation of existing butterfly pin protection needle guard.

Fig. 2 is the perspective view of a kind of embodiment of this utility model.

Fig. 3-Fig. 5 takes out the operating sequence sketch map of butterfly pin when being this utility model use.

Fig. 6-Fig. 8 recovers the operating sequence sketch map of butterfly pin when being this utility model use.

Fig. 9 is the structural representation of the another kind of embodiment of this utility model.

Figure 10-Figure 13 is the operating sequence sketch map of embodiment shown in Fig. 9.

At first, see also shown in Figure 2, butterfly needle safety needle cover 20 of the present utility model is the cylindric of hollow, a line of rabbet joint is offered in the upper end, this line of rabbet joint front end is " V " font and the introducing port 21 of circular arc slightly, a thin straight trough seam 22 is offered in the stage casing, and end is offered an elongated rectangular clamping slot 23, and these clamping slot 23 front ends are established two chamfer bevels; This butterfly pin 10 is placed through in the safe needle guard 20, and fin 13 supports of butterfly pin 10 are stuck in the clamping slot 23 of safe needle guard 20.

The enforcement motion flow of this utility model safety needle guard 20 sees also Fig. 3-shown in Figure 8, system was not fastened in the safe needle guard 20 when butterfly pin 10 used, at first, with finger with two fins 13 of butterfly pin 10 to intrinsic pressure, simultaneously butterfly pin 10 is pushed away forward, butterfly pin 10 can be released through the line of rabbet joint 22 of safety needle guard 20 upper limbs and break away from safe needle guard 20, inject, after treating that syringe needle 11 enters human body, unclasp two fins 13 of butterfly pin 10, this fin 13 is because of plastic material, and nature opens to both sides can be smooth on human body skin; Injection finishes, butterfly pin 10 is extracted human body, this moment, the operator gripped safe needle guard 20 on the other hand, another hands is pinched two fins 13 of folder butterfly pin 10, so both hands all are in syringe needle 11 rears of having been polluted, there has not been the danger of stabbing finger, the receipts of again this butterfly pin 10 being drawn back, by " V " fonts of safety needle guard 20 front ends slightly the introducing port 21 of circular arc enter, and the periphery of this introducing port 21 is coated with distinct eye-catching caution color, so the fin 13 of butterfly pin 10 1 sides is easier to rapidly and recovers safe needle guard 20 via the line of rabbet joint 22 accurately, enter the clamping slot 23 of safe needle guard 20 when the fin 13 of butterfly pin 10 2 sides, unclasp fin 13 again,, open to two sides to support to arrive in clamping slot 23 because of this fin 13 is a plastic material, this butterfly pin 10 can not come off and skid off, and reaches the practical effect of security protection.

Another embodiment of this utility model (seeing also shown in Figure 9), system is with the safe needle guard 30 left and right lines of rabbet joint of respectively offering, this line of rabbet joint front end is " V " font and the introducing port 31 of circular arc slightly, a thin straight trough seam 32 is offered in the stage casing, end is offered an elongated rectangular clamping slot 33, these clamping slot 33 front ends are established two chamfer bevels, and this butterfly pin 10 is set in the safe needle guard 30, and fin 13 supports of butterfly pin 10 2 sides fix in the clamping slot 33 of safty pin cover 30.

The enforcement motion flow of this utility model safety needle guard 30 sees also Figure 10-shown in Figure 13, system was not fastened in the safe needle guard 30 when this butterfly pin 10 used, at first, butterfly pin 10 is pushed away forward, butterfly pin 10 can be released through the line of rabbet joint 32 of safety needle guard 30 2 sides and break away from safe needle guard 30, inject, to be injected finishing, butterfly pin 10 is extracted human body, the operator grips safe needle guard 30 on the other hand, another pulls the pipe 12 of receiving safe needle guard 30 rears, so both hands all position are in syringe needle 11 rears of having been polluted, there has not been the danger of stabbing finger, when drawing when receiving pipe 12, this butterfly pin 10 can be rapidly accurately by safety needle guard 30 leading edges " V " font and slightly circular arc introducing port 31 recover safe needle guard 30 through the line of rabbet joint 32, the fin 13 of these butterfly pin 10 2 sides supports to arrive in and is snapped in the clamping slot 33, so butterfly pin 10 can not come off and skid off, and reaches the security protection effect.
