Description
Technical field
The purpose of this utility model is for a kind of blood taking needle is provided, and is specially a kind of safe retrieving blood taking needle, belongs to technical field of medical instruments.
Background technology
In clinical position, it is random, uncontrollable injecting relevant pricking wound, and nursing staff is the high-risk colony that pricking wound occurs.Unsafe injection comprises that to social harm needle sting after use other people and injection tool use that post processing is improper causes infecting diffusion socially.Standard precautions is to be proposed by the Center for Disease Control nineteen ninety-five, within 1996, implements in the whole America, and China 1999 introduces and within 2000, enrolling in " hospital infection management specification (the trying) " that Ministry of Public Health issues.Whether standard precautions viewpoint is thought: all patients' blood, body fluid, Excreta, secretions all have infectiousness, no matter there is obvious bloodstain to pollute or the skin mucosa of the incomplete property of no contact, 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 parts 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.A certain amount of negative pressure that vacuum test tube is preset in process of production, when after blood taking needle puncture intravasation, due to the suction function in blood taking tube, blood flows in blood taking tube automatically.For ensure use after blood taking needle do not stab medical worker, be also provided with protective sleeve.Existing protective sleeve has shell type protective sleeve, and this protective sleeve is difficult to upper syringe needle, and easily accidentally injures; Also have from backshank toward the cephalomotor slidingtype protective sleeve of pin; this protective sleeve is on protective sleeve, to be provided with axially open and stop projection; utilize the elasticity of protective sleeve; make the fin of holding pin slip into and be stuck in stop projection below; play a protective role; but this protective sleeve material is softer, also easily fin is deviate from.
In addition, also there is following defect in this blood taking needle: because vacuum test tube in assembly is really transparent, so can not know in time whether syringe needle is pricked on vein by blood.
Utility model content
The purpose of this utility model is for a kind of safe retrieving blood taking needle is provided, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of safe retrieving blood taking needle, comprises blood taking needle, connection tube and vacuum tube, and described blood taking needle is arranged on needle stand, and the lateral symmetry position of needle stand is respectively arranged with fin; The bottom of needle stand is connected with connection tube, is socketed with protective sleeve on connection tube; Described protective sleeve is made up of sleeve pipe and the hard sleeve squeezing handle that can accommodate blood taking needle, is provided with the chute mating with fin on described sleeve pipe; On described sleeve pipe squeezing handle, be provided with stopper slot, stopper slot is communicated with chute; Described chute width is reduced gradually by syringe needle to needle stand; The width of chute and stopper slot junction chute is less than the width of stopper slot; Described stopper slot height is slightly larger than the height of fin.
For the ease of blood taking needle fin is pushed to stopper slot, described cannula tip is designed to inclined-plane or curved surface, and the minimum point on the inclined-plane import department that is chute.
Further, consider the mechanics of fin in stopper slot, the probability in centre position is larger, therefore, and the lower end oral area of chute and the skew of the oral area of stopper slot; Shift ratio is 1:3.
Because sleeve pipe squeezing handle is hard material, therefore stopper slot can be not loose because of external force, and blood taking needle fin just can not skid off stopper slot yet, thereby more safe and reliable.
In order to exit from protective sleeve with limiting blood taking needle further, described chute middle part is set to arcuate structure.
Understand as early as possible blood taking needle for the ease of medical worker and whether inserted vein, described needle stand is set to transparent material.
The beneficial effects of the utility model are: 1, simple in structure, structure exquisiteness, dexterously stopper slot is opened to the squeezing handle place at hard material, and less by chute lower end oral area, blood taking needle fin is limited in stopper slot; Safe and reliable.2, by the chute setting of arcuate structure, can further place blood taking needle and skid off from protective sleeve; 3, the syringe needle polluting by closure after, blocked itself and extraneous direct contact, the probability of having cut off pricking wound prevented nursing staff's employment injuries, the while has also been alleviated the mental pressure of vast nursery work person's occupational exposure.
Brief description of the drawings
Fig. 1 is protective sleeve unused state structural representation of the present utility model;
Fig. 2 is protective sleeve using state structural representation of the present utility model;
In figure: 1, blood taking needle 2, fin 3, sleeve pipe 4, sleeve pipe squeezing handle 5, chute 6, stopper slot 7, connection tube.
Detailed description of the invention
Further set forth construction features of the present utility model below in conjunction with accompanying drawing and specific embodiment.
As depicted in figs. 1 and 2, a kind of safe retrieving blood taking needle, comprises blood taking needle 1, connection tube 7 and vacuum tube, and described blood taking needle 1 is arranged on needle stand, and the lateral symmetry position of needle stand is respectively arranged with fin 2; The bottom of needle stand is connected with connection tube 7, on connection tube 7, is socketed with protective sleeve; Described protective sleeve is made up of sleeve pipe 3 and the hard sleeve squeezing handle 4 that can accommodate blood taking needle, is provided with the chute 5 mating with fin 2 on described sleeve pipe 3; On described sleeve pipe squeezing handle 4, be provided with stopper slot 6, stopper slot 6 is communicated with chute 5; Described chute 5 width are reduced gradually by syringe needle to needle stand; Chute 5 width of chute 5 and stopper slot 6 junctions are less than the width of stopper slot 6; Described stopper slot 6 is highly slightly larger than the height of fin 2.
For the ease of the fin of blood taking needle 12 is pushed to stopper slot 6, described sleeve pipe 3 ends are designed to inclined-plane or curved surface, and the minimum point on inclined-plane is the import department of chute 5.
Further, consider the mechanics of fin 2 in stopper slot 6, the probability in centre position is larger, therefore, and the lower end oral area of chute 5 and the skew of the oral area of stopper slot 6; Shift ratio is 1:3.
Because sleeve pipe squeezing handle 4 is hard material, therefore stopper slot 6 can be not loose because of external force, and blood taking needle fin 2 just can not skid off stopper slot yet, thereby more safe and reliable.
In order to exit from protective sleeve with limiting blood taking needle 1 further, described chute 5 middle parts are set to arcuate structure.
Understand as early as possible blood taking needle 1 for the ease of medical worker and whether inserted vein, described needle stand is set to transparent material.
