Description
Technical field
This utility model relates to a kind of hemostix, is specially single use and bounces back safely hemostix, belong to technical field of medical instruments.
Background technology
In clinical position, the pricking wound that injection is relevant is random, uncontrollable, and nursing staff is the high risk group that pricking wound occurs.The harm of unsafe injection to society comprise the needle sting after use other people and injection tool use post processing improper cause infecting spread socially.Standard precautions is proposed by the Center for Disease Control nineteen ninety-five, within 1996, implements in the whole America, and China 1999 introduces and within 2000, to enroll in " hospital infection management specification (the trying) " that Ministry of Public Health issues.Whether standard precautions viewpoint is thought: the blood of all patients, body fluid, Excreta, secretions all have infectiousness, no matter have obvious bloodstain to pollute or whether contact the skin mucosa of incomplete property, all need to isolate.Therefore, a large amount of uses of disposable blood taking needle will bring the safe disposal problem of disposable blood taking needle.
Current normally used safe blood-taking needle, vacuum blood collector is made up of the several part of vacuum test tube, blood taking needle, connection tube and needle holder.Vacuum test tube is its key component, is mainly used in collection and the preservation of blood preparation.Vacuum test tube is prefixed a certain amount of negative pressure in process of production, and when after blood taking needle puncture intravasation, due to the suction function in blood taking tube, blood flows in blood taking tube automatically.In order to ensure that the blood taking needle after using does not stab medical worker, be also provided with protective sleeve.There is following defect in prior art: 1, existing protective sleeve has shell type protective sleeve, and this protective sleeve is difficult to upper syringe needle, and easily accidentally injures; 2, also have from backshank toward the cephalomotor slidingtype protective sleeve of pin, this protective sleeve is provided with axially open and stop projection on the protective sleeve, utilize the elasticity of protective sleeve, the fin holding pin is slipped into and is stuck in below stop projection, play a protective role, but this protective sleeve material is softer, also easy fin to be deviate from; 3, existing hemostix part is more, poor stability.
Utility model content
The purpose of this utility model is to provide single use to bounce back safely hemostix, to solve the problems referred to above of prior art.
The purpose of this utility model is achieved through the following technical solutions.
Single use bounces back safely hemostix, comprise blood taking needle and safety sleeve, an extensible member mated is installed, described extensible member arranged outside one elasticity salient point with safety sleeve in described safety sleeve, extensible member and blood taking needle connect also relative fixing, blood taking needle afterbody and tubes connection; Compress Spring is provided with between the inwall top of described extensible member and safety sleeve; Described safety sleeve is combined by two or more cartridge unit, is fixed by socket between two cartridge units; Position near upper and lower end face on safety sleeve sidewall is respectively arranged with the opening mated with the elasticity salient point of extensible member: trigger mouth and safe mouth; Be outside safety sleeve that the position of triggering mouth correspondence arranges a resilient contact; Described safe mouth is greater than the length of blood taking needle to the distance at safety sleeve top.
Described safety sleeve is oval, rotates to limit when extensible member and blood taking needle slide in safety sleeve, and causes elasticity salient point can not be corresponding with triggering mouth and safe mouth position.
Described extensible member is U-shaped, and the vertical arm of one of them is fixed with blood taking needle, the flexible salient point of arranged outside of another vertical arm.
The centre position of described safety sleeve is provided with squeezing handle, operates to facilitate medical personnel.
Between described cartridge unit, lap limits mobile by corresponding concave-convex design.
This utility model has following beneficial effect:
1, in safety sleeve, be provided with two openings, coordinate with elasticity salient point respectively, trigger mouth and can prevent blood taking needle from standing fast in blood collection procedure; Safe mouth can prevent blood taking needle from departing from sleeve when safe retrieving;
2, safety sleeve is set to ellipse, extensible member can not be rotated in safety sleeve, the position that both can realize elasticity salient point, triggering mouth and safe mouth is corresponding; Can limiting part be reduced again, improve stability.
3, adopt stagewise sleeve, be convenient to extensible member is installed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A portion structure for amplifying schematic diagram of Fig. 1;
Fig. 3 is the structural representation of this utility model safe retrieving state;
In figure: 1, blood taking needle 2, safety sleeve 3, extensible member 4, elasticity salient point 5, Compress Spring 6, triggering mouth 7, safe mouth 8, resilient contact 9, squeezing handle.
Detailed description of the invention
Construction features of the present utility model is set forth further below in conjunction with accompanying drawing and specific embodiment.
Bounce back safely with single use shown in Fig. 2 hemostix as shown in Figure 1, comprise blood taking needle 1 and safety sleeve 2, one extensible member 3 mated with safety sleeve 2 is installed in described safety sleeve 2, described extensible member 3 arranged outside one elasticity salient point 4, extensible member 3 and blood taking needle 1 connect also relative fixing, blood taking needle 1 afterbody and tubes connection; Compress Spring 5 is provided with between described extensible member 3 and the inwall top of safety sleeve 2; Described safety sleeve 2 is combined by two or more cartridge unit, is fixed by socket between two cartridge units; Position near upper and lower end face on safety sleeve 2 sidewall is respectively arranged with the opening mated with the elasticity salient point 4 of extensible member 3: trigger mouth 6 and safe mouth 7; Be outside safety sleeve 1 that the position of triggering mouth 6 correspondence arranges a resilient contact 8; Described safe mouth 7 is greater than the length of blood taking needle 1 to the distance at safety sleeve 2 top.
Described safety sleeve 2 is oval, rotates to limit when extensible member 3 and blood taking needle 1 slide in safety sleeve 2, and causes elasticity salient point 4 can not be corresponding with triggering mouth 6 and safe mouth 7 position.
Described extensible member 3 is U-shaped, the vertical arm of one of them is fixed with blood taking needle 1, the flexible salient point 4 of arranged outside of another vertical arm.
The centre position of described safety sleeve 2 is provided with squeezing handle 9, operates to facilitate medical personnel.
Between described cartridge unit, lap limits mobile by corresponding concave-convex design.
During installation, cartridge unit can be disassembled open, extensible member 3, Compress Spring 5, blood taking needle 1 (carrying pipe) are fixed, then successively through cartridge unit, and insert the cartridge unit on top smoothly.Until elasticity salient point 4 bullet of extensible member 3 enters to trigger mouth 6.Then other cartridge units are installed successively; The cartridge unit including safe mouth 7 is arranged on bottom, and opening direction is consistent with triggering mouth 6.
During blood sampling, hands squeezing handle 8 pushes.
During safe retrieving, with finger force pressing resilient contact 8, resilient contact 8 oppresses elasticity salient point 4, and elasticity salient point 4 is retracted from triggering mouth 6.Under the restoring force effect of Compress Spring 5, extensible member 3 and blood taking needle 1 bounce back to rapidly in safety sleeve 2.When elasticity salient point 4 arrives safe mouth 7 place, elasticity salient point 4 engages with safe mouth 7, and safety is fixing.Thus safe retrieving blood taking needle.
