As far as we know, the tip end of the needle is beveled into a sharp shape. 7〇Hold it. When in use, the medical staff removes the gold tube 7〇, and according to the doctor's procedure, the needle 55 is pierced into the predetermined position of the skin, and the flaps on the needle holder 5 are used (the single wing is commonly called the scalp needle, and the double wing is commonly called the butterfly needle). Make a paste with the skin to prevent the needle holder 50 from moving. After the needle is finished, the medical staff 'requires the whole set of infusion needle structure to be disposed of with waste. Before the discarding, the above tube 7 must be put back, but due to the sleeve 70 The caliber is very small, and it is difficult to complete the socketing operation. Therefore, the user is stabbed by a sharp needle during the socketing process. What is the case, because the casing 7 is small in size, it is inconvenient to store, the cake is silky, and the needle is needled. 55 people were exposed, so the medical staff and the follow-up Qinglong personnel were easily stabbed by the needle 55. In view of this, the creator is thinking hard, actively researching, and through continuous experimentation and improvement, finally developed this creation Q [ Creative content]: The purpose of this creation is to provide a simple, fast and will be able to use M289066

In order to achieve the above objectives, the techniques, components and means used are taken as a preferred example, and the following drawings are described below. [Embodiment]: As shown in Fig. 1~2, the infusion needle safety sheath of the present invention is a hollow tube body, which is arranged on the needle holder and the infusion tube in front of the needle, and includes: a cassette holder 30, The movable body is disposed on the infusion tube 2; and a tube body 4 is disposed behind the cassette holder 3; and a needle holder 50 > is disposed at one end of the infusion tube 2; by the combination of the above components, backward The cassette seat is pushed to form a latching effect with the needle holder 5, and the needle holder 50 is thus protected by the tube body 4〇. After the user injects, the cartridge 30 is only moved to the needle holder 5, and after the two are engaged, the needle is protected, which can avoid injury to the human body and has a safe and hygienic effect. As will be described in more detail below: As shown in Figures 1 to 3, the infusion needle safety sheath of the present invention is a hollow tube body, wherein the cassette holder 3 is movably disposed on the infusion tube, and a card chamber is disposed inside. 31, and at least one opening α 35 is set to place the clamping element, for example, the C-shaped piece 33, so as to have a +掣 effect; and at the same time, the chamber 32 is additionally disposed in front of the carding chamber u. The tube body 4 is disposed behind the cassette holder 30, and an opening is provided on the side thereof. When the needle holder 50 is snap-fitted with the cassette holder 30, the flap 52 can travel along the opening 41. After the needle holder 5〇 is sleeved on the infusion tube, the front end pre-twisting position si annular tapered protrusion 51 'the annular tapered protrusion si and the wing) ι 52 form a locking portion 53, and the locking portion 53 and the cartridge structure can be formed. A firm snap fit. As shown in Fig. 5, when the annular tapered projection 5i does not enter the C-shaped piece 33 M289066, the C-shaped piece 33 is in a state of being naturally open. As indicated by the circle 6, when the annular tapered projection 51 starts to enter the chevron 33, the C-shaped phantom opening gradually enlarges. As shown in Fig. 7, when the annular tapered projection 51 is about to pass through the C-shaped piece 33, the opening of the c-shaped piece 33 is expanded to the maximum.
如圖8所示，當環形錐狀突起51已經完全越過c 形片33時，C形片33恢復自然開口狀態，此時因環形 錐狀突起51之大徑比C形片33之内徑選要大 > 所以無 法再退回原來位置… 如圖3所示，使用針頭後，使用者將卡掣座移向針 碩卡合後，卡止部53阻止針座50向前，環形錐狀突起 5丄與C形片33形成的卡掣結構>使針座5〇亦不能向後， 此卡掣效果便可利用針座5〇後的管體4〇將針頭5s包 住’使用人員便不會受到針頭55刺傷。 在打針的過程中，為避免針頭移動，所以設翼片52As shown in Fig. 8, when the annular tapered protrusion 51 has completely passed over the c-shaped piece 33, the C-shaped piece 33 returns to the natural opening state, at which time the diameter of the annular tapered protrusion 51 is selected as compared with the inner diameter of the C-shaped piece 33. It is too large to return to the original position... As shown in Fig. 3, after the needle is used, after the user moves the cassette to the needle, the locking portion 53 prevents the needle holder 50 from moving forward and the annular cone is protruding. 5掣 and the C-shaped structure formed by the C-shaped piece 33> The needle holder 5〇 can not be turned backwards, and the click effect can be used to wrap the needle 5s with the tube body 4〇 behind the needle holder 5' Will be stabbed by the needle 55. In the process of injection, in order to avoid needle movement, the flap 52 is provided.
