A fastener hole is arranged on the protecting cap, a spring and a fastener are arranged on the needle handle, the fastener on the needle handle is in slide fit with the fastener hole on the protecting cap, by the aid of sliding of the protecting cap, fastening positions of the fastener and the fastener hole match with each other, so that a needle tip is protected by the protecting cap again after blood taking, secondary damage is avoided, and the possibility of infection of bloodborne pathogen is greatly reduced.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, is specifically related to a kind of novel blood taking needle.
Background technology
Along with the understanding gradually to infectious agent, numerous medical personnels have recognized that use has the sharp-pointed medical apparatus and instruments of safety guard, the importance that causes blood-borne pathogens to infect to avoiding stinging in the treatment process, hurting.Also correspondingly on the market be born that some have the hemostix of basic security protector,, all needed before use with hands protective cap is taken out earlier, therefore caused the inconvenience in the use as all being cast with the plastics protective cap on the needle point of hemostix.The retractable blood taking needle of some needle points is also arranged on the market in addition; For example number of patent application is that the patent publication of 2005200054RS.X discloses a kind of new disposable safe hemostix; It is made up of cabinet, the slide mass that has blood taking needle and starting switch and spring; The plastics protective cap of blood sampling needle point and the main part of slide mass are non-conjuncted moulding; Hemostix assembling and use before, the needle point protective cap is positioned at the outside of shell front end, the handle on the push-and-pull slide mass is prepared in the blood sampling needle point plastics protective cap and is received shell and stop automatically and come off.Press handle, hemostix promptly starts blood sampling.Above-mentioned new disposable safe hemostix is come off protective cap owing to stopping of shell under the handle that promotes on the slide mass; The bad control inconvenient operation of strength in this process; And outside needle point is exposed to after the blood sampling completion; Cause the secondary injury during collection easily, cause the infection of blood-borne pathogens.
The utility model content
It is a kind of easy to operate that this utility model provides, the novel blood taking needle of blood sampling back protective cap retraction.
In order to solve the problems of the technologies described above; This utility model provides following technical scheme: novel blood taking needle comprises shell, needle handle, nook closing member, protective cap; Described protective cap is provided with block button hole, and needle handle is provided with spring and buckle, and buckle on the needle handle and the block button hole on the protective cap are slidingly matched.Because protective cap is provided with block button hole; Needle handle is provided with spring and buckle; Buckle on the needle handle and the block button hole on the protective cap are slidingly matched; So can make the clamping matching in buckle and screens hole realize that blood drawing back needle point is protected the protection of medicated cap once more, has avoided the secondary injury, thereby has greatly reduced the possibility of infection of blood-borne pathogens through the slip of protective cap.
Further, described spring is coated on the outer surface of needle handle, and the movable end of spring connects protective cap; The stiff end of spring is located at the junction of needle handle and shell; The outer surface of spring coats transparent sleeve, and telescopic length is than the little 20mm of length of needle handle, and telescopic diameter is greater than the diameter of protective cap.Because spring is coated on the outer surface of needle handle, the movable end of spring connects protective cap, and the stiff end of spring is located at the junction of needle handle and shell; So after blood drawing, press buckle; Make buckle when block button hole withdraws from, under the effect of the recovery elastic force of spring,, needle point is protected once more the protective cap self-return; Again because the outer surface of spring coats transparent sleeve; Telescopic length is than the little 20mm of length of needle handle, and telescopic diameter is greater than the diameter of protective cap, and is so not only attractive in appearance but also let protective cap when sliding, be convenient to action.
Further, the length of described needle handle is than the big 15mm of length of protective cap, and buckle is positioned at the position apart from nook closing member and needle handle junction 15～20mm, and described buckle is located at the end of protective cap.Because the length of needle handle is than the big 15mm of length of protective cap; Institute is so that mounting spring; Space after having reserved the spring compression on the needle handle; Because buckle is positioned at the position apart from nook closing member and needle handle junction 15～20mm, and block button hole is located at the end of protective cap, make things convenient for the nurse to take a blood sample again so can nook closing member all be exposed during blood taking needle.
Further, described sleeve is provided with pushing plate near an end of needle point.Because sleeve is provided with pushing plate near an end of needle point, so the nurse conveniently is affectedly bashful and locatees in carrying out blood sampling work.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further detailed explanation:
Fig. 1 is the structural representation of the novel blood taking needle of this utility model.
The specific embodiment
As shown in Figure 1: novel blood taking needle comprises shell 1, needle handle 9, nook closing member 7, protective cap 8, and described protective cap 8 is provided with buckle 5, and buckle 5 is located at the end of protective cap 8; Needle handle 9 is provided with spring 4 and block button hole 6, and block button hole 6 is located at apart from the 15～20mm of needle handle 9 with shell 1 junction, and the block button hole 6 on the needle handle 9 is slidingly matched with the buckle 5 on the protective cap 8; The length of described needle handle 9 is than the big 15mm of length of protective cap 8; Described spring 4 is coated on the outer surface of needle handle 9, and the movable end of spring 4 connects protective cap 8, and the stiff end of spring 4 is located at the junction of nook closing member 7 and needle handle 9; The outer surface of spring 4 coats transparent sleeve 2; Sleeve 2 is provided with pushing plate 3 near an end of needle point, and the length of sleeve 2 is than the little 20mm of length of needle handle 9, and the diameter of sleeve 2 is greater than the diameter of protective cap 8.
Above-described only is the preferred implementation of this utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from this utility model structure, can also make some distortion and improvement; Should be regarded as the protection domain of this utility model, these can not influence effect and practical applicability that this utility model is implemented yet.
