Description
Technical field
The invention belongs to medical apparatus and instruments, specifically a kind of safe self-destroying transfusion injection needle that has movable protective sleeve.
Background technology
In the curative activity, people need often to use needle tubing, the syringe that uses during the treatment disease, and the sampler that uses during check all has needle tubing.For easy to operate, people often connect together needle tubing and needle stand and form the needle tubing assembly, are connected with syringe etc., finish the medical care precess task.The shortcoming of prior art is that transfusion injection needle uses the back needle tubing to be difficult for unmaking, the recycling of syringe or used after needle tubing accidentally injure.The hepatitis B that dangerous injection causes, hepatitis C and aids transmission have become serious public health problem.Therefore invent a kind of safe self-destroying transfusion injection needle, in the clinical treatment practice, have epochmaking realistic meaning.
Summary of the invention
The purpose of this invention is to provide a kind of safe self-destroying transfusion injection needle.
The object of the present invention is achieved like this.
The safe self-destroying transfusion injection needle that has movable protective sleeve, front portion are provided with needle tubing (1), needle tubing (1) is fixed on the front portion that needle stand (3) is gone up, needle stand (3) is fixed on tube for transfusion (6); The front portion of needle stand (3) is provided with annular recess (2); Needle stand (3) is provided with elasticity folder (5) with the junction of tube for transfusion (6), and the front portion of elasticity folder (5) is provided with lock tooth (4); The middle part of protective sleeve is provided with protecting tube (9), and the afterbody of protecting tube (9) is provided with afterbody groove (11), and the front portion of afterbody groove (11) is provided with two locking plates of 180 ° (10) each other.
The afterbody of tube for transfusion is provided with the connection spiral; The front portion that connects spiral is provided with operating grip.
The front portion of protecting tube is provided with butterfly-shaped hand-held sheet; The front portion of butterfly-shaped hand-held sheet is provided with two cue marks of 180 ° each other.
Main points of the present invention are: the outside at needle tubing is provided with protective sleeve, and protective sleeve can move forward and backward, and is fixed by locking plate, lock tooth.When moving forward, two locking plates of protective sleeve afterbody are stuck in the forward annular recess of needle tubing, and the position of protective sleeve is fixed, and needle tubing is enclosed in the protective sleeve, reaches the locking needle tubing, prevent needle tubing accidental injury human body, prevent reusable purpose.When needle tubing uses, for example injection, check sampling, the operator clutches elasticity with finger to be pressed from both sides, and elasticity is pressed from both sides forward lock tooth and is stuck in the protective sleeve afterbody groove, and protective sleeve is fixed on the rear portion of needle tubing, and needle tubing can use easily.Use and finish, finger is clutched the elasticity folder, moves forward protective sleeve, and two locking plates of protective sleeve afterbody are stuck in the forward annular recess of needle tubing, and the position of protective sleeve is fixed, protected cover self-locking of needle tubing and self-destruction.
For easy to operate, the present invention is provided with butterfly-shaped hand-held sheet in the front portion of protective sleeve, when protective sleeve moves forward and backward, hand-held butterfly-shaped easy to operate.The front portion of butterfly-shaped hand-held sheet is provided with two cue marks of 180 ° each other, and cue mark is identical with two locking plate angles of protective sleeve afterbody, is convenient to people's operation.
The present invention is provided with the connection spiral at the afterbody of tube for transfusion, so that needle tubing is connected with equipment such as samplers with syringe.Before connecting spiral, the tube for transfusion afterbody is provided with operating grip, operator's one hand-held operating grip, and the another hands is taken syringe, and is easy to connect.
Needle stand of the present invention is that duroplasts is made, to guarantee the not flexural deformation of annular recess on needle stand and the needle stand; Protecting tube of the present invention is that duroplasts is made, and is indeformable with locking plate, afterbody groove that assurance protecting tube and protecting tube are provided with; Convenient and needle tubing is used.
For easy to operate, tube for transfusion of the present invention, elasticity folder, lock tooth are that nylon material is made.The present invention can not establish Infusion clip according to needs of medical treatment on tube for transfusion, Infusion clip can be set yet.The Infusion clip that is provided with can be a plastic clip, also can be metal clip.
Ingenious being in protective sleeve and needle tubing of the present invention is provided with the locking plate and the annular recess of working in coordination, and makes protective sleeve be fixed on the needle tubing outside, the protection needle tubing; On protective sleeve and tube for transfusion, be provided with afterbody groove and lock tooth, make protective sleeve be fixed on the needle tubing rear portion, make things convenient for needle tubing to use.No matter protective sleeve is to be enclosed within needle tubing outer protection needle tubing, still makes things convenient for medical care precess at the needle tubing rear portion, can both accurately locate.The protected cover self-locking of needle tubing after having realized using and the goal of the invention of self-destruction have been finished the invention task.
The application target of the present invention and needle tubing is irrelevant, no matter is that injection, transfusion are used, and still the check sampling is used, and can use the present invention.The present invention and needle tubing size are irrelevant, no matter are big needle tubings, and still little needle tubing can use the present invention.The present invention and coupled syringe model, kind, material, size are irrelevant, and no matter syringe or check sampling device are that what model, kind, material, size can be used the present invention.
The present invention by the ingenious respective outer side edges of protective sleeve and syringe needle tube, has realized protected cover self-locking of needle tubing and the self-destroying function after the use by being provided with movably protective sleeve in the needle tubing outside.
The present invention is by structural design dexterously, solved the protected cover self-locking of needle tubing after the use that people thirst for solving for a long time and the technical barrier of self-destruction, is an invention that solves the technical barrier that people thirst for solving for a long time.
Patent documentation is consulted domestic and international public publication by retrieval, there is no the identical technical scheme with the present invention, and not seeing has the safety needle pipe that has movable protective sleeve with identical in structure of the present invention, so the present invention has novelty and creativeness; Because use generally in medical practice, the present invention has practicality widely.
Advantage of the present invention is:
Use the mobile protective sleeve in back; Promptly can prevent needle tubing accidental injury human body or repeated use to used needle tubing self-locking and self-destruction.
