Abstract
The present invention discloses a needle for injection, transfusion and blood transfusion, which has a self-destruction device. The aim of the present invention is to reach the goal of wide applicability, simple manufacture, low cost, convenient use and safe self-destruction after use. The present invention has the technical scheme to solve the technical problem that a connecting head of the ordinary needle for injection, transfusion and blood transfusion is covered by a needle tube protecting sleeve, and a needle seat is covered in a needle handle or the needle seat is arranged on the back end of the needle handle; the needle handle clamping is clamped on the connecting taper part of the needle seat and a guide tube, and other structure and use are similar with that of the ordinary needle for injection, transfusion and blood transfusion. After finishing injecting and transfusing liquids and drawing out the needle tube, doctors hold the connecting head by one hand and push the needle tube protecting sleeve downwards by the other hand, and the lower end face of the needle tube protecting sleeve firstly squeezes out of the tight cooperation of the needle handle clamping and the connecting taper part. After the lower end face of the needle tube protecting sleeve contacts with the end face of the needle handle, the needle tube is squeezed out and leaves the needle seat under the action of increasing a little push force, and the needle tube enters the needle tube protecting sleeve with the needle seat. The taper hole of the needle tube protecting sleeve is tightly attached to the connecting taper part and can not move. Thus, the needle for injection, transfusion and blood transfusion can not be used again, and the needle tube is also hid.
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 injected, 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 internal 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 destructing 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 comprise by union joint, needle tubing sheath, conduit, needle handle, needle stand, needle tubing, sheath and glue and forming.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; The front end inner chamber of conduit links to each other with the needle stand conical surface of needle stand rear end, and the other end of conduit links to each other with union joint; The front end sleeve of needle stand intracavity in needle handle, its needle stand front end is spacing at needle handle inner chamber conical surface place, needle stand step and needle handle inner chamber tight fit; 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, there are tapered hole and step in its rear end, 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 under the external force effect not having 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 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 conical surface place tight fit of seat during assembling, need allow two sides that clamp and the conduit conical surface that clamp seat break away from before injection, transfusion, blood transfusion needle destroy.For convenient production clamps seat and revolves with needle handle and turn 90 degrees manufacturing, clamp during assembling seat and needle handle to revolve turn 90 degrees after two sides that clamp and conduit conical surface 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 injected or the liquid of being totally lost after extract behind the needle tubing a portable union joint of living, one handgrip needle tubing sheath down pushes away, needle tubing sheath lower surface with clamp the oblique angle and contact, at first squeezing the run-bake-needle fault handle clamps and the tight fit that is connected the tapering place, with after the needle handle end face contacts, under the effect that strengthens some thrust, needle handle is squeezed out the disengaging needle stand in needle tubing sheath lower surface, needle tubing enters in the needle tubing sheath with needle stand, the internal 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 sheath end face exceeds needle point needle tubing has been concealed fully.
Other place similar to normal injection, transfusion, blood transfusion needle has just no longer 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.
