The following examples and the drawings are used to explain the present invention in detail: [Embodiment], and the fifth and sixth figures of the present invention are the safety injection needles of the present invention. 10, having at least one hollow cylinder-end opening 13 and a pressing member 14; wherein, 11, one end of the first connecting portion 12, 11; 12; the first connecting portion 12' is opened opposite to the end The end opening 13' of the hollow cylinder is located at the first connecting portion of the pressing member 14, and is movable at the opening 13 of the hollow cylinder a 200900103; 21 and a second connecting portion - the needle 2G, at least Having a total of 22; wherein: g the hollow needle 21, at least | + channel 212; 〃, with - oblique end surface 211 and an internal passage of the second connection portion 22, the system 1 is connected to the first connection The portion 12 is coupled to form a body; the & 1 full assembly 30' has a projecting-stop portion 33 and a linking portion 34; wherein: the connecting member and the hole are extending from the inner tube portion 31. The hollow needle tube 21; the communication hole 2 is located at the radial position of the end portion of the protruding inner tube portion 31, Attached to the end of the extended inner tube and located in the brother-connecting portion 22; §_ portion 34'_ to assist the pushing member to activate the broadcast portion ϋϋ > thereby, the security component 3G has at least a -th position ρι (such as a fifth entry 及 and a second position 2 2 (as shown in the tenth figure); when located at the first position P1 · the end of the inner tube portion 31 is located The inclined end surface 211 of the hollow needle tube 连通 communicates with the hollow barrel body. When the pressing member 14 interlocks the pushing portion 33, the safety assembly 30 is moved from the first 200900103 position Pi to the second position. Position P2; the stopping portion 33 covers one end of the inner passage 212; the communicating hole portion 32 is closed by the surface of the hollow needle tube 21 (also referred to as the surface of the _ portion passage 212); the protruding inner tube portion 31 extends out of the inclined end surface 211 of the hollow needle s 21, and the tool prevents the oblique end face from being a blunt object of a thorn-like creature such as a human body. This is the safe injection syringe of the present invention. In practice, the 'receiving portion 34 may be called a sensitive structure, or the bridging may be as shown in FIG. 5A, or may be connected to the supporting portion 33 (as shown in FIG. 5B). Treasury, tie _ push element 14. Regarding the use process of the present invention, as shown in the fifth and sixth figures, first, before the injection of the king/绮 syringe of the present month, the oblique end face m of the needle body is placed (for example, Entering the injection container 91 in the predetermined injection container 91 and then moving the pressing tree 14 relative to the h cylinder u (may also say that the pressing member 14 is outside the hollow cylinder 1) Pulling, that is, the injection product 91 flows from the inclined end surface 211 through the protruding inner tube portion 31, the communication hole portion 32, the inside of the second connecting portion 22, and the end opening 13 of the cylindrical body iq due to the pressure difference. Finally enter the hollow cylinder u. Until the shot body 11 is stored in a predetermined amount (usually based on the scale of the outer surface of the hollow cylinder u), the injection end 9 of the needle body 20 is pulled away from the injection object 91 (may also be said Take out the vial for storing the injection). Then, the cylinder 10 is held, and the needle 2 is inserted into the predetermined injected object 200900103 (as shown in the seventh figure, for example, inserted into the human body); and the hollow body 11 is then passed through the element 14 And the injection/protrusion 91 is injected into the injectable object 92 (in the process of pushing the injection 91, only the reverse operation of injecting the injection 91 into the hollow cylinder u) , not to be mentioned). When the injection product 91 is injected into the ^ 物 92 92 material, the 峨 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( The protruding inner tube portion 31 of the safety component 30 pushes out the hollow needle tube 21 obliquely = surface 211 (as shown in the ninth figure), since the protruding inner tube portion ^ is extremely consistent with the inner surface of the middle two needle f 21 , And having a frictional force, so that the protruding inner tube does not easily retreat after extending the inclined end surface 211, so that even the needle of the needle body 2〇 after the left shot (that is, the inclined end surface 211) is accidentally touched Touching the human body also makes the actual contact with the human body change "off, (not (four) puncture the skin) out of the inner tube 3 can effectively avoid, sharp" (four) puncture the skin of the needle: stab caused Serious problems with infectious diseases. § However, 'after the injection is completed,' even if the needle body 20 is not pulled away from the object to be injected 92, the pressing member 14 can be advanced to push the protruding inner tube portion out of the inclined end surface of the needle body 20. 211, because it only introduces a small section of pure tube (for example, the introduction of 2 5 coffee, that is, it has safety function), and the diameter is smaller than the needle body 20, and the needle body 2〇 is slightly forwarded, and then does not It will produce a bad shirt sound for the injected object, especially for the medical personnel, it can also produce better disease prevention and infection. 200900103 can have obvious results for medical staff and epidemic prevention work. > Read the tenth and tenth-figure 'in more detail, after the completion of the injection, continue to push the 7G piece of the 14G piece of fuel, and the extension of the inner tube part 31 of the safety squid 3G can be pushed out of the hollow needle 21 The inclined end surface 211 can simultaneously close the hollow needle tube 21 and the end of the protruding saddle portion 31. Since the pressing member 14 continues to push out the safety component 3G, if it is pulled back, the safety component 30 is not pulled back. Therefore, the front end of the needle body 2 is formed into a pure round tube, which cannot be repeated and used together. The needle body 20 can directly reduce the sharing rate of the needle body 2 (), and indirectly prevent the possibility of disease transmission through blood. *When the medical staff is in the action of returning the needle, the needle will be easily punctured by the needle. In addition, the medical staff will call Na safety gloves, and the safety component 3 is even more difficult to puncture the human body. To achieve the purpose of protecting the human body and bio-safety protection. The advantages and effects of the present invention can be summarized as: Π] effectively improve safety. By using the safety injection syringe of the present invention, after the injection is completed/extracted (for example, blood is drawn) (whether or not the body is withdrawn), the pushing member can continue to be advanced (still an injection action). The purely protruding inner tube protrudes out of the needle-small section, even if it accidentally touches the needle body (although the injecting personnel are very careful 'but still inevitable) 'actually it also touches the purely protruding inner tube part ( At most, it is "touching" the skin 'but not "puncture, skin", not being pinched by the needle to prevent blood-borne diseases. 12 200900103 ^ New (four) silk research _ Therefore. The present invention is fine injection Between the hollow cylinder of the Ten Commandments and the hollow needle tube, a safety component is added, and all the functions of the existing syringe are completely saved. In the process of injecting the medicine, the bottom of the surface is simultaneously pushed out of the inner tube of the safety component. The needle body - small section, the more, the main shooting action fusion '--------------------------------------------------------------------------------------------------- [3] Just change the financial structure freshly. The needle disc body of the present invention is provided with a safety component which is actually only a hollow tube having a communicating hole portion and an auxiliary push rod 'structure phase # simple, and the existing structure can be simply modified. It can also be used for the safety of the appropriate size of the single county H, or the needle of the safety component, which can be used with the general syringe. The cost is low and the safety is high. ...[4] The extension of the inner tube portion beyond the hollow needle tube cannot be retracted, and the syringe can be prevented from being reused. The blunt-shaped protruding inner tube portion of the present invention has no design to be pushed back (or pulled back) after being pushed out of the inclined end surface of the hollow needle tube, so that as long as the injection process is actually completed (in the process of injection, it is illusory, The blunt extension of the inner tube portion extends out of the hollow needle, and the needle body cannot be injected again. This effectively prevents the unscrupulous person from repacking the syringe, or the operator may reuse the needle. The above is only by better. The invention is not limited to the spirit and scope of the invention. It is to be understood by those skilled in the art that the present invention can achieve the foregoing objects.
