Description
Technical field
This utility model relates to disposable medical instrument field, particularly a kind of Anti-stabbing remaining needle.
Background technology
Modern medical skill generally adopts disposable Disposable syringe.Disposable syringe is that extract puncture needle out, and make indwelling needle be retained in human vein, indwelling needle can connect drop or other intravenous injection devices after puncture passages through which vital energy circulates.
And indwelling needle is as disposable medical apparatus, after abandoning, its needle tip easily causes the unexpected injury of pinprick.If set up retention device to needle tip, cost is relatively high, and structure is complicated again.
Utility model content
It is with low cost that this utility model is intended to propose one, the simple Anti-stabbing remaining needle of structure, it comprises for the indwelling when puncturing in intravenous indwelling portion and pluggable the puncture portion inserted in described indwelling portion, it is characterized in that, described puncture portion comprises the first end being provided with piercing needle, and second end contrary with described piercing needle, described second end is fixed with the elastic device of the Axis Extension along described piercing needle, described elastic device comprises the stiff end fixed with described second end and the free end being provided with door, described elastic device is movable along the axis direction of described piercing needle between its compression position and extended position, when described compression position, described elastic device compresses and described piercing needle is exposed, when described extended position, described elastic device is freely stretched and is blocked the needle point of described piercing needle by described door.
In a preferred embodiment, described elastic device is the spring be enclosed within along the axis direction of described piercing needle on described piercing needle.
Further, described indwelling portion comprises holding unit, when described piercing needle inserts in described indwelling portion, described holding unit against the free end of described spring door thus described spring is remained on its compression position.
Preferably, described door is disk or columnar structured, and described door is provided with through hole for making described piercing needle through described through hole, described door, along with the free end of described spring, does axial-movement along described piercing needle.
Specifically, the through hole on described door is located at 1/4 place of the diameter of door.
Especially, described door is fixed to described free end by binding agent.
Advantageously, second end in described puncture portion is provided with Handheld Division.
Adopt the Anti-stabbing remaining needle of this utility model structure, on the one hand after puncture terminates, door can bottle up piercing needle automatically, prevents from stabbing medical personnel, avoids injuring other people and infecting other pathogenic bacterias; On the other hand, its simple structure, material cost and assembly cost cheap.

Fig. 2 is the using state decomposing schematic representation of the Anti-stabbing remaining needle in Fig. 1.
Fig. 3 be this utility model one embodiment door on through hole setting position schematic diagram.
Detailed description of the invention
This utility model embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 2 shows the using state decomposing schematic representation of the Anti-stabbing remaining needle of this utility model one embodiment.Wherein, this remaining needle comprises: for the indwelling when puncturing in intravenous indwelling portion 1 and pluggable the puncture portion 2 inserted in described indwelling portion.
Puncture portion 2 comprises the first end being provided with piercing needle 21, and second end contrary with described piercing needle 21.Second end in puncture portion 2 is provided with handle 5.Described second end is fixed with the spring 3 along the Axis Extension of described piercing needle, and it comprises the stiff end fixed with the second end and the free end being provided with door 4.The axis direction of spring 3 along described piercing needle 21 between its compression position (shown in Fig. 2) and extended position (shown in Fig. 1) moves back and forth.As when the compression position of the spring shown in Fig. 2, spring 3 compresses and described piercing needle 21 is exposed, when the extended position of the spring shown in Fig. 1, spring 3 is freely stretched and is blocked the needle point 211 of piercing needle 21 by door 4, thus avoid preventing from stabbing medical personnel, and avoid injuring other people and infecting other pathogenic bacterias.
The axis direction of above-mentioned piercing needle refers to the direction of the longitudinal axis along piercing needle.
Preferably, door 4 is disk or columnar structured, and described door is provided with through hole for making described piercing needle through described through hole, described door, along with the free end of described spring, does axial-movement along described piercing needle.Preferably, the through hole on described door is located at 1/4 place of the diameter of door, is not namely located at the center (as shown in Figure 3) of the disk of described door.
Further as shown in Figure 2, indwelling portion 1 comprises holding unit 11, when piercing needle 21 inserts in indwelling portion 1, spring is remained on its compression position by the door table that holding unit 11 is resisted against the free end of spring.Holding unit 11 can be the needle cylinder type structure shown in Fig. 2, and the diameter of its syringe is less than the diameter of door, thus plays against door and the effect of Compress Spring.
In one embodiment, door 4 is fixed to the free end of spring by binding agent.
During use, during puncture, piercing needle 21 inserts in the needle cylinder type structure of holding unit 11, due to the effect of holding unit, by spring-compressed, thus needle point is exposed.When extracting piercing needle after completing puncture, the elastic force of spring ejects door, just covers the metal needle point of piercing needle, is covered by needle point, play protective action.
By the mode of exemplary embodiment, exemplary explanation is carried out to this utility model above, but this utility model is not limited thereto.Be construed as, when not departing from design of the present utility model, operation principle, the equipment in above embodiment, material, install and use other that know by the art personnel and to replace or equivalent processes is replaced.This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
