Description
Technical field
The present invention relates to a kind of hemostix, specially disposable safety retraction hemostix belongs to medical device technology
Field.
Background technology
In clinical position, it is random, uncontrollable to inject relevant needle and stab, and nursing staff is that needle thorn occurs
The high risk group of wound.After unsafe injection includes needlestick injuries after use other people and injection tool use to the harm of society
Manage it is improper cause infection socially spread.Standard precautions were proposed by the Center for Disease Control nineteen ninety-five, and 1996 complete
U.S. implements, and China introduces and be incorporated into what the Ministry of Public Health issued in 2000 for 1999《Hospital infection management specification (tentative)》In.Mark
Standard is prevented viewpoint and is thought：Blood, body fluid, excreta, the secretion of all patients all has infectiousness, whether has apparent
Bloodstain pollutes or whether contacts the skin and mucosa of incomplete property, is both needed to be isolated.Therefore, a large amount of uses of disposable blood taking needle
The safe disposal problem of disposable blood taking needle will be brought.
Safe blood-taking needle usually used at present, vacuum blood collector is by vacuum blood collection tube, blood taking needle, connecting tube and needle holder
Several part compositions.Vacuum blood collection tube is its chief component, is mainly used for the acquisition and preservation of blood preparation.Vacuum blood collection
Pipe is prefixed a certain amount of negative pressure in process of production, after pin puncture of taking a blood sample enters blood vessel, since the negative pressure in heparin tube is made
With blood automatically flows into heparin tube.In order to ensure that the blood taking needle after use does not stab medical worker, it is additionally provided with protective case.
The prior art has the following defects：1, existing protection is cased with shell type protective case, and this protective case is difficult to upper syringe needle, Er Qierong
Easily accidentally injure；2, also have from backshank toward the cephalomotor slidingtype protective case of needle, this protective case is to be equipped with axial open on the protective sleeve
Mouth and stop projection make the fin for holding needle slide into and are stuck in below stop projection using the elasticity of protective case, play protection and make
With, but the material is soft for this protective case, also is easy to deviate from fin；3, existing hemostix part is more, and stability is poor.
Invention content
The purpose of the invention is to provide disposable safety retraction hemostix, asked with solving the above-mentioned of the prior art
Topic.
The purpose of the present invention is achieved through the following technical solutions.
Disposable safety retraction hemostix, including blood taking needle and safety sleeve install one in the safety sleeve
With the matched extensible member of safety sleeve, an elastic salient point is arranged in extensible member outside, and extensible member is connect with blood taking needle and phase
To fixation, blood sampling Aculeata is connect with conduit；It is provided with compressed spring between at the top of the extensible member and the inner wall of safety sleeve；
The safety sleeve is composed of two or more cartridge units, is fixed by socket between two cartridge units；Pacifying
It is respectively arranged with and the matched opening of the elastic salient point of extensible member close to the position of upper and lower end face in full sleeve lateral wall：Trigger mouth
With safety mouth；It is that triggering the corresponding position of mouth is arranged a resilient contact on the outside of safety sleeve；The safe mouth is to condom
The distance at cylinder top is more than the length of blood taking needle.
The safety sleeve is ellipse, to limit extensible member and when blood taking needle slides in safety sleeve revolves
Turn, and causes elastic salient point corresponding with triggering mouth and safe mouth position.
The extensible member is U-shaped, and blood taking needle is fixed in the vertical arm of one of them, bullet is provided on the outside of another vertical arm
Property salient point.
The centre position of the safety sleeve is provided with squeezing handle, to facilitate medical staff to operate.
Lap is limited by corresponding concave-convex design and is moved between the cartridge unit.
The invention has the advantages that：
1, there are two openings for setting in safety sleeve, coordinate respectively with elastic salient point, and triggering mouth can prevent blood taking needle from existing
It stands fast in blood collection procedure；Safe mouth can prevent blood taking needle to be detached from sleeve in safe retrieving；
2, safety sleeve is set to ellipse so that extensible member cannot rotate in safety sleeve, can both realize elasticity
The position of salient point, triggering mouth and safe mouth corresponds to；Limiting component can be reduced again, improve stability.
3, using segmented sleeve, it is easily installed extensible member.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the portions the A enlarged structure schematic diagram of Fig. 1；
Fig. 3 is the structural schematic diagram of safe retrieving state of the present invention；
In figure：1, blood taking needle 2, safety sleeve 3, extensible member 4, elastic salient point 5, compressed spring 6, triggering mouth
7, safe mouth 8, resilient contact 9, squeezing handle.
Specific implementation mode
Below in conjunction with the accompanying drawings with the specific embodiment design feature that the present invention is further explained.
Disposable safety retraction hemostix shown in as shown in Figure 1 and Fig. 2, including blood taking needle 1 and safety sleeve 2, institute
An elastic salient point is arranged in installation one and 2 matched extensible member 3 of safety sleeve in the safety sleeve 2 stated, 3 outside of extensible member
4, extensible member 3 connect and is relatively fixed with blood taking needle 1, and 1 tail portion of blood taking needle is connect with conduit；The extensible member 3 and safety sleeve 2
Inner wall at the top of between be provided with compressed spring 5；The safety sleeve 2 combined by two or more cartridge units and
At being fixed by socket between two cartridge units；On 2 side wall of safety sleeve close to upper and lower end face position be respectively arranged with
The 4 matched opening of elastic salient point of extensible member 3：Trigger mouth 6 and safe mouth 7；1 outside of safety sleeve is that triggering mouth 6 is corresponding
A resilient contact 8 is arranged in position；The distance at the safe mouth 7 to 2 top of safety sleeve is more than the length of blood taking needle 1.
The safety sleeve 2 is ellipse, to limit extensible member 3 and when blood taking needle 1 slides in safety sleeve 2
Rotation, and cause elastic salient point 4 corresponding with triggering mouth 6 and 7 position of safe mouth.
The extensible member 3 is U-shaped, and blood taking needle 1 is fixed in the vertical arm of one of them, is provided on the outside of another vertical arm
Elastic salient point 4.
The centre position of the safety sleeve 2 is provided with squeezing handle 9, to facilitate medical staff to operate.
Lap is limited by corresponding concave-convex design and is moved between the cartridge unit.
When installation, cartridge unit can be disassembled and be opened, extensible member 3, compressed spring 5, blood taking needle 1 (carrying pipe) is fixed
It is good, cartridge unit is then sequentially passed through, and be smoothly inserted into the cartridge unit on top.Until extensible member 3 elastic salient point 4 snap into it is tactile
Send out mouth 6.Then other cartridge units are installed successively；It will include that the cartridge unit of safe mouth 7 is mounted on bottom, and be open
Direction is consistent with triggering mouth 6.
When blood sampling, hand squeezing handle 8 pushes.
When safe retrieving, with finger force press resilient contact 8, resilient contact 8 oppress elastic salient point 4, elastic salient point 4 from
It triggers and retracts at mouth 6.Under the recovery force effect of compressed spring 5, extensible member 3 and blood taking needle 1 bounce back to rapidly safety sleeve 2
It is interior.When elastic salient point 4 reaches at safe mouth 7, elastic salient point 4 is engaged with safe mouth 7, and safety is fixed.To which safe retrieving is taken a blood sample
Needle.
