Abstract
A syringe needle for anesthesia belongs to a medical product. The syringe needle comprises a connector and a steel needle which are separately arranged; one side of the connector connected with a syringe is provided with a thin film; one side of the connector connected with the steel needle is provided with a conical opening of which the diameter ranges from 2.1 to 0mm from outside to inside and the inner wall has elasticity; and the side face of the connector is provided with a through hole of which the diameter is 0.1mm. Because the syringe needle is provided with the thin film and the conical opening, an anaesthetic and an anticoagulant can be added at the connector. Therefore, after the syringe is full of injection, the syringe needle replaces the conventional syringe needle to inject the injection for the patient, and the pain caused by pricking the syringe needle into skin and flesh can be relieved through dual effect of the anaesthetic and the anticoagulant.
Description
Technical field
A kind of anesthesia belongs to medical supplies with injection needle.
Background technology
Present stage, the injection syringe needle all has only a needle point, and measuring the big more pairing syringe needle of syringe will be thick more; The pain that produces in the time of injection will be more severe; Especially for the child, intensive pain can make the syringe needle of hiding of child's instinct, is unfavorable for the cooperation between the medical care.
Summary of the invention
In order to address the above problem, to the utility model discloses a kind of anesthesia and use injection needle; After needle tubing is taken out full injection, to use this utility model syringe needle and replace original syringe needle and give patient infusion, the anaesthetic that can be through being contained in blank area and the dual function of anticoagulant alleviate syringe needle and penetrate the pain in the skin and flesh.
The purpose of this utility model is achieved in that
Injection needle is used in a kind of anesthesia, comprises the joint and the draw point of configured separate, and the side that said joint is connected with needle tubing is provided with thin film; A side that is connected with draw point is provided with from outside to inside diameter by the inwall rubber-like tapered opening of 2.1mm to 0mm; The through hole that to be provided with a diameter in the side of joint be 0.1mm.
Injection needle is used in above-mentioned a kind of anesthesia, and said film surface has cut, and the direction of cut is from the center of circle to the circumference, and cut is to be that symmetrical centre is symmetrically distributed with the center of circle.
Injection needle is used in above-mentioned a kind of anesthesia, and said cut is 4,8 or 16.
Injection needle is used in above-mentioned a kind of anesthesia, and said through hole is sealed by paraffin.
Because this utility model syringe needle is provided with thin film and tapered opening; Therefore can add anaesthetic and anticoagulant at blank area; Therefore after needle tubing is taken out full injection; Use this utility model syringe needle and replace original syringe needle, can alleviate syringe needle through the dual function of anaesthetic and anticoagulant and penetrate the pain in the skin and flesh to patient infusion.
Description of drawings
Fig. 1 is this utility model injection needle sketch.
Among the figure: 1 joint, 2 draw points, 3 thin film, 4 tapered openings, 5 through holes.
The specific embodiment
Below in conjunction with accompanying drawing this utility model specific embodiment is described in further detail.
Injection needle is used in a kind of anesthesia, comprises the joint 1 and the draw point 2 of configured separate, and the side that said joint 1 is connected with needle tubing is provided with thin film 3; A side that is connected with draw point 2 is provided with from outside to inside diameter by the inwall rubber-like tapered opening 4 of 2.1mm to 0mm; The through hole 5 that to be provided with a diameter in the side of joint be 0.1mm, as shown in Figure 1.
Before syringe needle uses,, and guarantee that through hole 5 is in the top at first with joint 1 horizontal positioned; Utilize other ordinary syringe to inject anaesthetic and anticoagulant from tapered opening 4; When the metering of anaesthetic and anticoagulant is enough, with through hole 5 sealings, and extract syringe with paraffin; Tapered opening 4 closures make anaesthetic and anticoagulant be in closed state.
In use, draw point 2 is inserted from tapered opening 4, and joint 1 is linked to each other with needle tubing.Because the side that joint 1 is connected with needle tubing is provided with thin film 3; And this film surface has direction for from the center of circle to the circumference; And with the center of circle 8 cuts that symmetrical centre is symmetrically distributed; Make this thin film 3 by the bursting of the jag of needle tubing institute, in the push rod pushing course of needle tubing, anaesthetic and anticoagulant are at first injected in the body.
Claims (4)
