Description
Technical field:
This utility model relates to technical field of medical instruments, and exactly, it is a kind of disposable venoclysis needle safe in utilization.
Background technology:
Venoclysis needle is the most frequently used, one of the simplest medical apparatus and instruments, constitutes transfusion device together with tube for transfusion.Along with development of technology, it develops into present disposable occupation mode by original repeatedly sterilization, repeated use mode.Fig. 1 is exactly the structural representation of the present soft double-vane handle of the disposable use venoclysis needle of using always, and it is made according to State Standard of the People's Republic of China GB18671-2002, among the figure: the 1st, needle guard, the 2nd, syringe needle, the 3rd, double-vane, the 4th, connect flexible pipe, the 5th, needle stand.During use, remove needle guard 1, after syringe needle 2 penetrates vein, utilize adhesive tape that double-vane 3 is fixed on the human body skin.Though the transfusion needle of this double-vane structure has fixing reliable advantage, syringe needle be difficult for to produce " prick and leak " or syringe needle and phenomenon such as deviates from the infusion process, but when pulling out pin, at first, medical personnel must very separate fixed double-vane carefully from human body skin, and then syringe needle is extracted out from vein, in double-vane and the skin separation process, needle point very easily scratches vein blood vessel, and is careless slightly or move and excessively just blood vessel is damaged.So existing soft double-vane handle venoclysis needle not only causes unnecessary malpractice easily, increased difficulty also for medical personnel's intravenous injection.
In addition, because existing soft double-vane handle venoclysis needle does not have self-destroying function, handle a little just reusable, in case reuse accidentally, just very easily cause the cross infection of hematopathy such as acquired immune deficiency syndrome (AIDS), hepatopathy or other diseases, thereby society is caused great harm.Moreover, the unshielded measure of the syringe needle after the use, exposed also can handle and make troubles outside to Biohazard Waste, the punctures packing material also can pollute environment.
Summary of the invention:
This utility model is the technological improvement to existing soft double-vane handle venoclysis needle, its purpose just provides a kind of fixing reliable, easy to use, particularly can avoid blood vessel wall is caused unnecessary damages, and have the venoclysis needle disposable safe in utilization of self-destruction and useless syringe needle safeguard procedures simultaneously.
The purpose of this utility model is to realize like this.Disposable venoclysis needle safe in utilization comprises slip sheath, shank, pulls out pin handle, syringe needle and flexible pipe, needle guard (12) is enclosed within on the syringe needle (11), flexible pipe (19) is connected to tube for transfusion through needle stand (20), it is characterized in that: syringe needle (11) is contained in the front end of shank (14), the rear end of shank (14) is provided with pulls out pin handle (18), slip sheath (16) is enclosed within on the shank (14), and the tail end of shank (14) connects flexible pipe (19); The front portion of shank (14) is provided with exterior bayonet slot (13); Pull out pin handle (18) and be provided with outer fixture block (17); The inside of slip sheath (16) is provided with interior fixture block (22), and circle is provided with inner card cage (21) in the rear portion, and double-vane (15) is equipped with in the front portion; Double-vane (15) also can adopt the single-blade form.Before the use, the outer fixture block (17) that pulls out on the pin handle (18) is stuck in the inner card cage (21) of slip sheath (16); After the use, the interior fixture block (22) of slip sheath (16) is stuck on the forward exterior bayonet slot of shank (14) (13), protects syringe needle (11).
Compared with prior art, this utility model is keeping on the fixing reliable basis of soft double-vane handle venoclysis needle, do not need elder generation that the double-vane of fixation is separated from human body skin when pulling out pin, can be with syringe needle along extracting out in the slip sheath, separate double-vane after pulling out pin earlier, thereby fundamentally avoided because of separate double-vane cause accidentally the blood vessel injury may, make also that operation of medical workers is more free and relaxed, working strength further reduces.Pull out in the pin process, slip sheath reach also is stuck on the shank, again can't after move, promptly brought into play self-destruction, prevented to reuse, avoid cross infection; Simultaneously, the slip sheath is enclosed within on the exhausted syringe needle, has guaranteed to handle the safety of medical waste again, prevents the pollution of medical waste to environment.

The specific embodiment:
Embodiment 1:
This utility model all can adopt plastics to make except that syringe needle 11, and needle guard 12, flexible pipe 19 and needle stand 20 are same as the prior art, and needle stand 20 is also same as the prior art with the connected mode of tube for transfusion.As shown in Figure 1, needle guard 12 is enclosed within on the syringe needle 11, and flexible pipe 19 is connected to tube for transfusion through needle stand 20, again to infusion bottle.Syringe needle 11 can be installed in the front end of shank 14 with Shooting Technique, and the rear end of shank 14 is provided with pulls out pin handle 18, and both are bonding to be integral.Slip sheath 16 is enclosed within on the shank 14, and the tail end of shank 14 connects flexible pipe 19.The front portion of shank 14 is provided with exterior bayonet slot 13, pulls out pin handle 18 and is provided with outer fixture block 17, and the inside of slip sheath 16 is provided with interior fixture block 22, and circle is provided with inner card cage 21 in the rear portion.Before the use, the outer fixture block 17 that pulls out on the pin handle 18 is stuck in the inner card cage 21 of slip sheath 16; After transfusion finishes, needn't separate fixing between double-vane 15 and the human body skin, press the outer fixture block 17 that pulls out on the pin handle 18, again shank 14 is twitched backward along slip sheath 16, as shown in Figure 2, extracting from the patient vessel, slide until syringe needle 11, the interior fixture block 22 of sheath 16 is stuck in the shank 14 forward exterior bayonet slots 13, slip sheath 16 protects syringe needle 11, at last double-vane 15 is taken off from human body skin.After interior fixture block 22 was stuck in the exterior bayonet slot 13, slip sheath 16 just again can't retreat or be sleeved on again on the shank 14, promptly produces self-destroying function; Slip sheath 16 protects syringe needle 11, with the processing that makes things convenient for medical waste, prevent that medical dirt from polluting environment.Double-vane 15 can adopt Shooting Technique to be fixed on the front end of slip sheath 16.
Embodiment 2:
Double-vane 15 on this utility model slip sheath 16 also can adopt the single-blade form.
