New description: [New technical field] This creation is about the type of blood collection needle structure, especially the disposable blood collection needle. [Prior Art] According to the approved 092209425 "Safety Device for Blood Injection Needle" patent, it consists of a single-input double-needle base unit and an injection dragon; its casing unit can make double 2 The pedestal single it is completely covered inside, which constitutes the safety of the blood-sucking needle. However, the double-needle base unit of the above case is pumped in the injection syringe, and the method is broken. Damage, so the possibility of using the syringe again can not be avoided; the problems faced in this case, especially for its years of involvement in the research and development of the industry, manufacturing practice experience, the possibility of preventing the injection syringe from being used again Improvements [New Content] The purpose of contact ΐΪ 2 is to provide a disposable pick-and-pin structure. By rotating the body seat, the rotation of the body seat can selectively release or lock the needle directly. Pushing the pusher can push the needle piece away from the swivel seat of the syringe part, instead of feeding the powder head part, throwing the contact part with the needle item to avoid the danger of stabbing and improving safety. Sex. The safety of the pipe fittings _ structure ' _ abandoning time ' is reversed by the guiding protrusions on the core s ship needle parts, so that the needle on the needle piece can not be exposed again to avoid the stab wound. Dangerous, and the collection of blood, the position of the bumps, so that the needle will remain in the state of the exposed casing to facilitate the disease. Q, the safety of the use of blood collection and the prevention of the use of the needles after cleaning, the second purpose of the use of the above-mentioned purpose and efficacy 'the technical means adopted, including a needle-shaped needle device has a blood collection tube and The lancet includes: a syringe member, and the slewing seat is provided with at least one positioning portion, wherein the portion is rotated to the positioning and the rotation is rotated, and a needle is obtained. The extension extends a card to the end.

The specific method used in the step 2 is to be carried out by the following embodiments and the accompanying drawings. [Embodiment] Body Description: Needle: The system includes: a syringe member 1〇 and a needle member 20/mating port' for blood drawing, and the blood collecting needle and pin member 10 has a hollow cylinder single πΓ^ΓΡ 110 ?, Hi^ 110 .1, the end face is provided with an end hole 113 which is open to the outside. 111 ' 112 121 ' 122 ^ swivel=1^ The groove structure in which the U1, 112 moves. The swivel seat 12 is as 122= : Parts (1), 112 ':; Γ-进• and _ unit==:== M436461 The other end of the swivel seat 12 corresponds to the end hole 113 of the needle member 10. The lock hole 123' Making the lock hole of the swivel seat 12 The needle member 20 has a needle member that is open 1 , s * ^ has a soft sleeve 212 at one end, and the needle member 2 is not at the needle member = -1 end - the needle 2U, and the other portion 213. The needle member 2 〇 The soft sleeve 212 of the card needle unit 21 extends outwardly from the middle portion of the needle member as shown in Fig. 6; the liquid guide needle of the second ==2 is passed through the keyhole (2) as shown in the figure 畀The end hole 113 of the needle piece 10 enters the inside of the hollow cylindrical unit u. The keyhole 1M has an opening shape with a locking amount of 5 213 123 = 113 as shown in Figs. 3A and 4A and is locked to the barrel member 1 The upper part of the 小 小 〇 〇 使 使 使 使 使 使 使 使 使 使 使 使 使 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The locking hole (2) is disposed such that the opening σ direction of the locking hole 123 is incorrect as shown in FIG. 5A'5B to lock the locking portion 213; otherwise, after the blood collection, the rotating seat is also rotated to The opening direction of the locking hole 123 corresponds to the locking portion 2U as in the third, and the needle member 20 is separated from the needle 1G in the drawing. In the design of the present invention, the locking hole 123 is controlled by the rotation of the body 12 The direction of the opening The needle member 2g is not contacted, and the head member 20 is selectively rotated or locked to the syringe member 10. In the case of blood collection, the blood vessel τ is taken inside the empty cylinder unit u, and the liquid guiding needle Will extend out of the soft cannula into the inside of the syringe 1 as shown in Figure 6 and penetrate into the blood collection tube τ, and connected to the blood collection tube τ, so that blood can be collected through the needle member 2 through the liquid guiding needle 2d Referring to Figures 7 and 8, it is a perspective view and an exploded perspective view showing the second embodiment of the present invention. The main components of the blood collection needle 1 in the second embodiment are the same as the first embodiment. The same functions as in the first embodiment are given the same reference numerals, and the description thereof is omitted. In the second embodiment, the lancet 100 is provided with a push-out piece 214 之间 between the needle 211 and the locking portion 213. In the embodiment, the ejector piece 214 is adjacent to the locking portion 213 and extends further beyond the locking portion. The end of 213. 5 M436461 'Shift' turns the swivel seat 12 to the direction of the opening of the lock hole 123 and the locking portion 213. When the needle 2G and the syringe member 1G are used, the needle member of the needle member 2ΐ can be pushed by (4) pushing the #214A The swivel seat 12 of the f-cylinder piece 1〇 allows the needle unit 20 to be separated without having to directly hold the needle, and is discarded to avoid the risk of being stabbed by the needle 211. FIG. 9 shows the creation of the present invention. The third embodiment is an exploded perspective view of the third embodiment. The third embodiment is the same as the first embodiment, and has the same functions as those of the first embodiment, and the same reference numerals are used and the description thereof is omitted. The needle in the bucket f is also the same as the needle member 20B in the needle 211 and the locking portion 213 2MA 'and the second and the second is the same as the second 14 = the touch block 215B ' and further includes the 栌 22 ^ ^ Β A guide groove 22〇B is disposed at a position where the corresponding guide protrusion 21 is made, and the guide protrusion 215B is moved in the groove by the guide bow 1 of the guide groove. The groove 22 has a front end portion 221B and a rear end portion 222b and extends rearward at the rear end thereof. There is a rear end and a groove is provided at the end portion 221Β. The convex portion 225 Β and the needle 211 on the needle 单元 = needle unit 21 will remain in the exposed sleeve member after the addition of the guide groove to the fine groove along the guide groove from the front end thin end Ϊ 22 The B end portion 222B' is further locked by the broadcast to the end portion 224B of the guide groove following the groove, as shown in FIG.
