Abstract
The invention relates to an injection needle with self-damage device, wherein it has simple production and low cost; the production comprises: sheathing tube protective sleeve on the generator connector; the base is sheathed inside the handle or at the back end of handle; the handle is clamped at the connection taper between base and the tube; the inventive structure and application is similar with the general one; when doctor has injected and drawn out the tube, suspending the connector, and pushing down the protective sleeve; the lower end of sleeve contacts the end surface of handle; and the handle will drop from the base via large pushing force; the tube with base will enter into the sleeve; the taper hole of sleeve will be stick with the connection taper to avoid displacement.
Description
Affiliated technical field
Patent of the present invention relates to disposable medical instrument, and patent especially of the present invention relates to a kind of injection with the destructing safety device, transfusion, blood transfusion needle.
Background technology
Medical injection, transfusion, blood transfusion needle are medical apparatus and instruments commonly used, and injection, transfusion, blood transfusion needle are mainly used in the syringe coupling and realize liquid medicine injection, realize loading liquid with the transfusion device coupling, mate with the blood exchange transfusion set and realize blood transfusion etc.
Normal injection, transfusion, blood transfusion needle have a lot of dissatisfactory places after medical treatment is used: the first uses the back excellent, and some lawless persons can pack once more and put goods on the market; It two is that sheath is not easy to continue to be enclosed within on the needle handle needle tubing is concealed, and outside needle tubing was exposed to fully, medical personnel and patient were in cleaning, easy accident is subjected to pricking wound etc. when discarded.Normal injection, transfusion, blood transfusion needle have become a social problem because of the above-mentioned undesirable cross infection that causes with being not intended to stab at present.Especially the viral communication person is used will be prudent in dealing with especially.Thereby each state all drops into a lot of human and material resources and designs better product and solve this social problem.
The technical solution adopted for the present invention to solve the technical problems is: at the union joint place of normal injection, transfusion, blood transfusion needle cover winding the needle tube sheath, needle stand is enclosed within the needle handle or needle stand places the needle handle rear end, needle handle clamps and is stuck in needle stand and is connected the tapering place with conduit, and other structure and use are to common similar.The doctor has annotated, has been totally lost and extracted behind the needle tubing a portable union joint of living behind the liquid, one handgrip needle tubing sheath down pushes away, needle tubing sheath lower surface is at first squeezed the run-bake-needle fault handle and is clamped and the tight fit that is connected the tapering place, in needle tubing sheath lower surface with after the needle handle end face contacts, under the effect that strengthens some thrust, needle handle is squeezed out the disengaging needle stand, and needle tubing enters in the needle tubing sheath with needle stand, the taper hole of needle tubing sheath be connected tapering place fitting together and can not move tightly.Injection like this, transfusion, blood transfusion needle can not reuse, and needle tubing has also concealed.
Summary of the invention
The object of the present invention is to provide injection, transfusion, the blood transfusion needle of band self-destruction and safety device, this destructing safety device can be after use destroyed and needle tubing be hidden from view.Avoided the lawless person to have an opportunity to take advantage of, packing listing has once more avoided accident to stab the people.
A kind of injection with the destructing safety device provided by the present invention, transfusion, blood transfusion needle, it is made up of union joint, needle tubing sheath, conduit, nook closing member, needle handle, needle tubing, sheath.Wherein needle tubing is connected needle stand front end tapered hole with glue, and needle handle clamps and is stuck in needle stand and is connected the tapering place with conduit; Conduit links to each other with the needle stand rear end; The other end of conduit links to each other with union joint; The front end sleeve of needle stand is in the needle handle endoporus; Sheath is enclosed within the needle handle front end; The needle tubing sheath is enclosed within on the conduit.
This safety device needle tubing sheath rear and front end communicates, and there are tapered hole and step in the rear end, and the bore of tapering is less than the external diameter of conduit, and the interference fit place forms the conduit impression, to such an extent as to their frictional force can not relatively move there be not under the external force effect greatly.
Embodiment one needle stand front end has tapered hole, and middle-end has step, and the rear end is a taper.
Embodiment one needle handle is that straight hole and taper hole combine, upper rear end has step, there is handle sheet (can have only has the handle sheet on one side) on both sides, its right-hand member clamps seat, clamping seat links to each other by muscle with needle handle, clamp two sides that clamp and the conduit tapering face place tight fit of seat during assembling, injection, transfusion, blood transfusion needle need allow before destroying two sides that clamp that clamp and conduit tapering emaciated face from.For convenient produce to wait clamp seat and can revolve with needle handle and turn 90 degrees manufacturing, clamp seat during assembling and will revolve and turn 90 degrees two sides that clamp, back and conduit tapering face place tight fit.
Embodiment two and embodiment one different being: needle tubing matches with the needle handle inner chamber, and needle stand places the rear end face of needle handle.
Medical personnel have injected, have been totally lost and extracted behind the needle tubing a portable union joint of living behind the liquid; one handgrip needle tubing sheath down pushes away; needle tubing protective sleeve lower surface with clamp inclined-plane contact and at first squeeze the run-bake-needle fault handle and clamp and the tight fit that is connected the tapering place; in needle tubing protective sleeve lower surface with after the needle handle end face contacts; under the effect that strengthens some thrust; needle handle is squeezed out the disengaging needle stand, and needle tubing enters in the needle tubing protective sleeve with needle stand, the taper hole of needle tubing protective sleeve be connected tapering place fitting together and can not move tightly.Injection like this, transfusion, blood transfusion needle can not reuse, and needle tubing sheath lower surface exceeds needle point needle tubing has been concealed fully.
Other is similar to normal injection, transfusion, blood transfusion needle just no longer to have explained.
The present invention has following characteristics: the suitability is wide, makes simply, and cost is low, and is easy to use, uses the back destructing safety.
