New description: [New technical field] This creation is related to a disposable needle set, especially one that can automatically hide the needle after use, without contacting the used needle, and avoiding the needle Dispose of the disposable needle set structure. [Prior Art] According to the current general medical examination process, it is necessary to frequently use injection or invasive blood collection devices. For example, in order to effectively control the blood sugar concentration of diabetic patients, medical personnel must use a blood collection device to stab patients every day. The skin is used to collect blood samples. The blood sample taken is then dropped on the test piece, and the test piece is inserted into the blood glucose meter to read the blood glucose concentration of the blood sample. A similar blood collection device mainly penetrates the skin of a patient through a needle and contacts the blood of the patient, so that the disease is transmitted through the blood through the needle (such as AIDS, type B, hepatitis C, etc. up to more than 20 kinds). It can not be ignored, and the traditional blood collection needle is either a traditional needle or a vacuum blood collection needle. • The tip of the contaminated needle is exposed to the outside, which is easy to cause needle stick injury and cannot protect the safety of medical personnel. Therefore, how to deal with the lack of operation of the conventional blood collection needle, to ensure the safety of the relevant personnel in use, to avoid the user accidentally contact with the used needle, or deliberate repeated use, it is the industry or The intellectuals should further think and try to break through the important issues. 3 [New content] ί ί ί ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' Its main purpose. #为上上目, the creation of the disposable needle set is a floating sleeve, a needle, a compression bomb f, and a seesaw unit in an outer sleeve; wherein the needle is buried in the floating sleeve, Synchronous with the floating sleeve: the relative displacement of the sleeve; the one end of the floating sleeve is provided with a protective cover opposite to the outer sleeve, the dustproof (four) can be removed for the needle, the needle tip is exposed The two fixed ends of the compression magazine are respectively fixed to the outer sleeve and the sleeve. When the force is not applied, the needle is hidden inside the outer cylinder; as for the plate unit The floating sleeve is limited to the position where the collapse spring is squeezed, and the restriction on the floating sleeve can be released by the user as desired. In the case of the disposable needle set of the present invention, the protective cover is removed first, and after the piercing of the sleeve is directly opposite the use part, the pressing unit can release the restriction on the floating sleeve, and the floating sleeve is set by the compression spring. The cartridge, together with the needle, is ejected instantaneously in the direction of the white perforation, so that the needle protrudes from the perforation of the outer sleeve and penetrates into the use portion, and when the compression spring returns to the unstressed free state, i pulls the floating sleeve and the needle back. The needle is hidden inside the outer sleeve, and is not in contact with the used needle, and the compression spring also exhibits a free stretch state without force, and the floating sleeve and the needle can no longer be ejected, thereby avoiding being hit. Deliberately repeated use. The second purpose of this creation is to shield the needle from the shield and to provide a fast rhyme (four) handle set or not by the presence of the (4) shield. Text M374359 [Embodiment] The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the embodiments. As shown in the first figure and the second figure, the disposable needle set of the present invention comprises: an outer sleeve 10, a floating sleeve 20, a needle 30, a compression elastic 40, and a plate assembly 50; Wherein: the entire barrel of the outer sleeve 10 is formed by joining two cylinders 11 and is a cylindrical structure for accommodating the related members, one end of which one end of the tube Φ body 11 is fastened There is a perforation 12. The floating sleeve 20 is disposed inside the outer sleeve 1b, and one end thereof is provided with a protective cover 21 opposite to the through hole 12 of the outer sleeve 1, and the protective cover 21 can be removed during use. The needle 30 is embedded in the floating sleeve 20 and is relatively displaceable with the outer sleeve 10 with the floating sleeve 2, and can be exposed to a needle tip of a specific length after the shield 21 is removed. The compression spring 40 is disposed inside the outer sleeve 1 , and the two fixed ends φ are respectively fixed to the outer sleeve 1 〇 and the floating sleeve 20 , and when the compression spring 40 is unstressed, The appearance of the needle 3〇 hidden inside the outer sleeve 1〇 is shown. The plate assembly 50 is configured to limit the floating sleeve 2 to a position where the compression spring 40 is pressed, and the user can press the user to release the restriction on the floating sleeve 20; The plate unit 5 has a pressing member 51 exposed to the barrel of the outer sleeve 10, and the barrel of the outer sleeve 1 is oppositely provided with a recess 13 for accommodating the pressing member 51 to avoid accidental contact with the plate during handling. Unit 50. The disposable needle set of the present invention is firstly used as shown in the third figure, M374359, to remove the protective cover relative to the outer sleeve 10, so that the needle tip of the needle 3 is relatively exposed to the floating sleeve 20, and the outer After the perforation 12 of the sleeve 1 is facing the use portion 60, the pressing plate unit 50 can release the restriction on the floating sleeve 2〇. As shown in the fourth figure, the floating sleeve 2〇 is combined with the needle by the compression spring 4〇. 3〇 Instantly ejects in the direction of the perforation 12, so that the needle 2 〇 extends relatively out of the perforation 12 of the outer sleeve 1 and penetrates into the use portion 60, thereby completing the needle-punching action of blood collection. And, when the compression spring 40 ejects the floating sleeve 2〇 together with the needle 3〇 in the direction of the perforation 12, it will immediately return to the unstressed free state as shown in the fifth figure, and once the floating sleeve 2 is The needle 3 is pulled back so that the needle 30 is hidden inside the outer sleeve 1〇 without being in contact with the used needle ' to ensure the safety of the person concerned. Furthermore, the disposable needle set of the present invention can be shielded from the needle 30 by the shield 21 (as shown in the second figure), and the presence of the shield U can be used to quickly identify the disposable needle set. No; and, after the entire set of disposable needle sets is used and the needle is automatically hidden inside the outer sleeve, as shown in the fifth figure, the compression spring 4 is unstressed and free to stretch, and can no longer be The floating sleeve 2〇 and the needle 30 are ejected to avoid deliberate repeated use. To sum up, this creation provides a better and feasible disposable needle set, and applies for a new patent according to law; the technical content and technical characteristics of this creation are disclosed above, but those familiar with the technology may still be based on this The creation of the creation and the various changes and modifications that do not depart from the creative spirit of the case. Therefore, the scope of protection of this creation should not be limited to those disclosed in the examples, but should include various substitutions and modifications that do not depart from the creation and are covered by the following scope = scope.
