Description

Disposible safety syringe
Technical field
The present invention relates to medical instrument fields, in particular to disposible safety syringe.
Background technique
It is also the maximum medical instrument of usage amount that current injector, which is the most frequently used, in recent years in order to control iatrogenic infection Disease avoids the adverse consequences such as cross-infection, is generally deposited and is protected after use using disposable sterilized injector but existing syringe It deposits intact still reusable and is on the one hand utilized vulnerable to criminal after injection the defects of syringe needle leakage without safety device, It is used syringe is not sterilized and reuse, the propagation and cross-infection of virus are easily caused, is on the other hand infused Outside the needle body penetrated still is trapped in, carrying, the destruction for not being only syringe rubbish for the acuity of syringe needle are brought Inconvenience, while the thing because stabbing medical staff accidentally also constantly occurs, and the cross-infection of germ just inevitably occurs.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides disposible safety syringes, and easy-to-use, effect can It leans on, needle tubing remains in the solution cavity of retraction injection tube while injection is completed, it is ensured that medical staff avoids by pollution needle point Unexpected injury, avoid medical staff and catch because of needle stick injury.
In order to achieve the above object of the invention, the technical solution adopted by the present invention is：
Piston rod is arranged in disposible safety syringe, including steel needle, injection tube, piston rod and piston handle, the piston handle One end, the piston handle further include on the outside of injection tube：Hemispherical rubber stopper, frustum cone cylinder and preceding cylindrical drum, the frustum cone cylinder are set It sets when injection tube is in syringe use close to one end of skin, the frustum cone cylinder is fixedly connected with preceding cylindrical drum, and the steel needle is solid Surely inner cylindrical tube is connected, the cylindrical outer tube circumference is fixedly attached rubber tube, and the inner cylindrical tube is placed in inside injection tube, makes When with syringe, the one end inside injection tube that is located at of cylindrical drum before the rubber tube is interference fitted, the piston rod is fixedly connected In interference fit with the hemispherical rubber stopper of frustum cone cylinder, the hemispherical rubber stopper is equipped with the cylinder in interference fit with inner cylindrical tube Rubber bumps.
Further, when preparing using syringe, the rubber bumps connect inner cylindrical tube, will be interior inside injection tube The steel needle of cylindrical drum connection pushes outside injection tube, until rubber tube is completely into preceding cylindrical drum.
Further, the rubber tube is identical as preceding cylindrical drum height.
Further, it completes using after syringe, hand piston handle is pulled away from, at this point, the inner circle toward the direction far from skin Column casing moves together with rubber bumps, until steel needle enters in injection tube.
Beneficial effects of the present invention are：
For the present invention when preparing using syringe, the rubber bumps connect inner cylindrical tube, inside injection tube, by inner cylindrical tube The steel needle of connection pushes outside injection tube, until rubber tube is completely into preceding cylindrical drum.It completes to live manually using after syringe Handle is filled in, is pulled away from toward the direction far from skin, at this point, the inner cylindrical tube moves together with rubber bumps, until steel needle enters note In shooting cylinder.Easy-to-use, reliable effect, needle tubing remains in the solution cavity of retraction injection tube while injection is completed, it is ensured that doctor Shield personnel avoid avoiding medical staff by the unexpected injury of pollution needle point and catching because of needle stick injury.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
The appended drawing reference table of comparisons：
Cylindrical drum, 8- before 1- piston handle, 2- piston rod, 3- injection tube, 4- hemispherical rubber stopper, 5- rubber bumps, 6- steel needle, 7- Inner cylindrical tube, 9- rubber tube, 10- frustum cone cylinder.
Specific embodiment
Further illustrate a specific embodiment of the invention with reference to the accompanying drawing.Wherein identical components are with identical Appended drawing reference indicates.
It should be noted that word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to Direction in attached drawing, word "inner" and "outside" refer respectively to the direction towards or away from geometric center of specific component.
In order that the present invention can be more clearly and readily understood, following will be combined with the drawings in the embodiments of the present invention, Technical scheme in the embodiment of the invention is clearly and completely described.
As shown in Figure 1, disposible safety syringe, including steel needle 6, injection tube 3, piston rod 2 and piston handle 1, the work One end of piston rod 2 is arranged in plug handle 1, and the piston handle 1 further includes in 3 outside of injection tube：Hemispherical rubber stopper 4, frustum cone cylinder 10 and preceding cylindrical drum 7, injection tube 3 is arranged in when syringe is used close to one end of skin, the rotary table in the frustum cone cylinder 10 Cylindrical drum 7 before cylinder 10 is fixedly connected, the steel needle 6 are fixedly connected with inner cylindrical tube 8, and 8 excircle of cylindrical drum is fixedly attached rubber Packing element 9, the inner cylindrical tube 8 are placed in inside injection tube 3, and when using syringe, the rubber tube 9 is interference fitted preceding cylindrical drum 7, the 3 inside one end of injection tube that is located at of the piston rod 2 is fixedly connected with the hemispherical rubber stopper 4 in interference fit with frustum cone cylinder 10, The hemispherical rubber stopper 4 is equipped with the cylindrical rubber protrusion 5 in interference fit with inner cylindrical tube 8.
The rubber tube 9 is identical as preceding 7 height of cylindrical drum.
When preparing using syringe, the rubber bumps 5 connect inner cylindrical tube 8, inside injection tube 3, by interior cylinder The steel needle 6 of 8 connection of cylinder pushes outside injection tube 3, until rubber tube 9 is completely into preceding cylindrical drum 7.It completes to use syringe Afterwards, hand piston handle 1 is pulled away from, at this point, the inner cylindrical tube 8 moves together with rubber bumps 5, directly toward the direction far from skin Enter in injection tube 3 to steel needle 6.
