[Prior Art] It has become an inevitable fact that medical staff have been accidentally injured by needle injection because of the operation of the syringe. According to the Center for Disease Control and Preventi〇n, the United States consumes 6 billion syringes a year. On average, there are 8〇~1〇() 10,000 cases of acupuncture accidents, and about 18,000 medical personnel are infected with hepatitis B due to acupuncture. Therefore, the “coating safety syringe” that prevents needle sticks is mushrooming. The company is continuously being introduced, for example, US Patent Nos. US2571653, US4790827, US4631057, US4850994, US4915702, M394823 US4976702, US4998920, US4998924, US5207646, US5674203, US5735823, US5947933, US6149630 And US67〇2786, etc. are all disclosed. However, the various conventional jacket-type safety syringes disclosed above have caused syringe manufacturers to be unwilling to introduce them into production due to a number of defects. The reasons are as follows: 1. First, the above-mentioned conventional US patent US4976702 is taken as an example, as in the first As shown in the third to third figures, the structure is such that each of the two ends of the outer peripheral surface of the syringe 1 is recessed with an upper concave ring groove. And a concave ring groove lb, and a plurality of convex granules 2b (as shown in the third figure) arranged at intervals on the inner wall surface of the outer rim 2a of the outer manpower 2 and the external tamper 2 (the needle lc is not performed) Before the injection of the medicament, the outer sleeve 2 is wrapped on the syringe 1 and is snapped into the concave ring groove lb of the syringe 1 by the ring projection 2b on the inner wall surface of the sleeve 2a, so that they are mutually Fixed without detachment (as shown in the second figure), when the needle 1C completes the injection, then hold the outer sleeve 2 by hand and apply force: (4) k-square ' 'straight _ ring bulge 2b card When the syringe U is inserted into the concave ring groove 1a, the needle U can be wrapped in the outer sleeve 2 (as shown in the first figure), and the medical staff can be prevented from directly hitting the needle lc. There are two missing structures in the & structure, Γ Ο 1 4 M394823 First, because the outer ring surface of the syringe is provided with a concave ring groove and a concave ring groove lb, the original injection mold will be used. Can't continue to use, must spend another time to make a new syringe mold, and then, any finished product of the syringe after changing the structure, according to US drugs The Food and Drag Administration (FDA) regulations must re-apply for re-inspection applications, while fda has certain specifications and review time for medical device testing procedures. Manufacturers still have to wait until they receive inspections. After the qualified notice, the adjustment of the production line operation process can be started. Therefore, the manufacturer will be interested in the disadvantages such as waiting for the FDA to review and not being able to determine when the mass production can be started, and the additional expenditure of making new molds. There is no intention to change production, after all, time is money; second, as shown in the fourth and fifth figures, when the outer sleeve 2 fits over the outer surface of the syringe 1, due to the outer sleeve 2 The inner diameter dimension formed by the ring 2b on the sleeve 2a is smaller than the outer diameter d2 of the syringe 1, so the two lugs on the outer edge of the sleeve 2a must be grasped by a clamp or other tools. 2c, re-synchronizing the two sides of the radial direction to open the fitting opening 2a (as indicated by the two arrows Fv in the fifth figure), and the ferrule 2& which is opened is changed from the original circular diameter In the elliptical caliber (as shown in the imaginary line portion in the fifth figure), and the deformed elliptical sleeve 2a, there is a case where the right side of the circular syringe 1 cannot be immediately placed on each other. After a large external force forces the outer sleeve 2 to pass through the top outer surface of the cylinder 1 + ΤΪΓ 4 π, it will again encounter the concave ring groove 1 & 2 (as shown in the imaginary line in the fourth figure), but The external force is applied again to open the fitting opening 2a, so that the ring 2b of the outer sleeve 2 finally reaches the position of the concave ring # lb, so that the difficult assembly process is not suitable for the current mass production mode. Safe syringe process 'and according to the World Health Organization (W〇rld heart 01^1112.... 11, referred to as WHO) statistics, the annual consumption of global traditional syringes is about 400-60 billion 1 think? The assembly of the sleeve - the difficulty of supporting the syringe 1 and the outer sleeve 2 is already quite high, and it is even more difficult to meet the production demand of the year. 2, taking the above-mentioned US Patent No. 463 l〇57 as an example. As shown in the sixth and seventh figures, the structure is composed of a hollow annular fixing seat 3 and an outer sleeve. The fixing base 3 is sleeved on the top outer edge surface of the syringe 5, and the concave ring groove 3a' under the semicircular section of the ring is recessed near the outer edge surface of the needle 5C end and is close to the syringe barrel 5. The outer edge surface of the P-end of the push rod is recessed " another loop of the concave ring groove on the v-shaped section, and the inner end of the outer sleeve 4 is adjacent to the inner side of the outer sleeve 4 a semi-circular cross-section of the rib ring 4a and a 圃vv & 乂-shaped cross-section of the angular convex ring 4b; before the needle 5C is not injected, the outer sleeve 4 of the convex assist ring 4a is buckled In 6 |^J /-^-r 疋3 l under the concave ring groove 3a (as shown in the sixth figure), after the needle 713 is injected, the outer sleeve 4 is held by hand and the force is pulled toward the needle c. And until the corner ring 4b is snapped into the concave ring groove 3b of the fixing seat 3 I, the needle can be "wrapped in the outer sleeve 4 (as shown in the seventh figure), and the medical personnel are prevented from directly touching The needle head 5C is tied Accident; where 'the structure of the syringe 5 is the same as that of a conventional syringe', so it does not have to re-make the syringe mold' but still exists - a serious lack, as shown in the eighth to twelfth figures due to the outer sleeve 4 The inner diameter of the corner ring 4b is 1. The outer diameter d4 of the outer surface of the fixing seat 3 (as shown in the ninth figure), when the outer sleeve 4 and the fixing base 3 are placed on each other, it must be in the sleeve. After the force is applied to the opposite sides of the joint 4c I, it can be inserted into the outer edge surface of the solid seat 3 (as indicated by the two arrows η in the eighth figure), but the ferrule 4c is opened. The shape will be changed from the original circular diameter to a round shape... as shown in the imaginary line part of the eighth figure), so that the deformed elliptical sleeve opening 4c can not immediately interact with the outer surface of the circular fixing seat 3 The phenomenon of arranging (as shown in the tenth figure), if a large external force is used to force the outer sleeve 4 to pass through the top outer edge surface of the fixing seat 3, it will still encounter the upper and lower concave ring groove & Tenth - as shown in the figure), but it is necessary to apply an external force again to pounce the hoop to continue to move forward. Once again, it will encounter the blockage of the upper concave ring groove 3b (such as the flute country and Liu tenth - the figure does not), so it is necessary to apply [S] 7 M394823 external force again to open the ferrule 2a' through the aforementioned difficulties. The assembly process can complete the assembly of the outer sleeve 4 and the syringe U, and therefore is not suitable for the safety syringe process of the current mass production mode. It is known from the above-mentioned U.S. Patent Nos. 4,976,702 and US 463 1057 that the lack of structural design is the biggest P that prevents the jacket-type safety syringe from entering the production market. In addition, the current law has not been mandatory, that is, it is not feasible to require the syringe manufacturer to take the initiative to produce a safe syringe, and the manufacturer is less willing to invest or introduce the production of the safety syringe under economic considerations. The medical waste disposal personnel can only continue to be threatened by the accidental puncture of the needle being injected. In view of this, the creators of this case have actively conducted in-depth research and carried out many experimental trials after the cooperation of the existing automatic special mechanical equipment. I can finish this creation. [New content] The main purpose of this creation is to provide a kind of "protective device for syringe needle", which consists of a lower ring seat, - 1 , a set ring upper ring seat and a sleeve composed of 'the lower ring seat and the upper ring seat The sleeves are respectively fixed on the outer green surface of the syringe, and the sleeve is sleeved on the outer ring surface of the lower ring seat and the upper ring seat. The inner wall surface of the bottom surface is convexly provided with a circle of ribs 8 from the bottom surface to the side. A long crack groove is formed on each surface, and a groove is further connected to the bottom of the two long crack grooves, wherein the length of the @long crack groove is perpendicular to the convex rib ring, and the convex The thickness of the intersection of the rib ring and the two long crack grooves is smaller than the thickness of the rib ring. When the sleeve is sleeved on the lower ring seat and the upper ring seat, the opening of the bottom surface is biased and then ribbed. The ring will also be opened at the same time, and the shape of the rib ring after the expansion will be formed into a circular shape by an elliptical shape, so that the circular ring seat or the upper ring seat cannot be mutually nested. The existing automatic special machine B can be broken and applied to the jacket safety note. In addition to improving the manufacturer's willingness to invest in safe syringes, it is more conducive to the early elimination of medical doctors _ needle accidents _:: the disposal of waste disposal personnel: the purpose is to provide - "injection needles" Uniform connection: due to the two long crack slots in the sleeve and the bottom of the groove [embodiment] The buckle strength of the lower-ring groove. The rib ring is buckled to the lower ring seat. Please refer to the thirteenth to eighteenth drawings. As shown, the present invention "protective device for a syringe needle" includes: - a ring seat 10' is a transparent hollow ring body and is sleeved on the outer edge surface of the bottom end of the syringe 1, the diameter of the inner ring is The outer peripheral surface of the syringe 1 has the same diameter, and a ring-shaped concave ring groove 11 is recessed on the outer ring surface; an upper ring seat 20' is a transparent hollow ring body and is sleeved on the outer peripheral surface of the top end of the syringe 1. The diameter of the inner ring is the same as the diameter of the outer peripheral surface of the syringe i. The inner middle portion of the outer annular surface is recessed with a ring of concave groove grooves 21' from the upper concave ring groove 21 to the outer end surface of the upper ring seat 20 The annular surface is formed as a tapered cone 22, and the outer ring between the upper concave ring groove 21 and the top end surface of the upper ring seat Then, a ring stop flange 23 is provided, wherein the outer diameter dimension d5 of the stop flange 23 is larger than the outer diameter dimension d6 of the tapered cone 22 (as shown in FIG. 15); and a sleeve 30 'The sleeve is placed on the outer ring surface of the lower ring seat 1〇 and the upper ring seat 2〇, which is a transparent hollow cylindrical body whose total length is shorter than the total length of the syringe 1 'opened on the top surface 31 - The hole 32 is penetrated, and a ring rib ring 34 is protruded from the inner wall surface near the bottom surface 33, and a long crack is formed on the side surface 35 at a position spaced apart by 180 degrees. a groove 36, and a groove 33 is further connected to the groove bottom of the two long slit grooves 36, wherein the length of the 10 groove 36 is perpendicular to the groove width of the groove rib ring 34, and the width is small 】 In the aperture of the tension 1 37, the thickness of the intersection of the two long slit rib rings 34 and the bite 36 is self-produced t7 r ^ & U is smaller than the rib ring twist t2 (such as the eighteenth figure) Shown). As shown in the 19th to 25th, the combination of the syringe and the 10th and 4th steps of the syringe and the steps are as follows: a. First fix the lower ring seat 10 to the barrel The outer edge surface (as shown in the nineteenth figure. Note b) and then the upper ring seat 2〇 cover surface (as shown in the twentieth figure); the ZW end outer edge 33 of the arm R first clip Holding the hook... face (such as the twentieth-figure force Fv, the hemp, 1 towards < work direction on both sides of the d7 will also / &open; open and the inner step of the rib ring 34 Following the disintegration deformation (as shown in Fig. 22, the opening shape of the bottom surface 33 of the sill S will be changed from a circular aperture to an elliptical aperture (as ^^ (as shown in Fig. 12), but the convex The rib ring 34 is deformed into a circular shape due to the thickness of the joint between the two long splits and the "fourth" slot 36 (1 ^ ^ thickness t2), which is deformed into a circular shape (such as the twenty-fourth figure). As shown in the figure), the circle will not be blocked during the rear-end stitching process. Furthermore, the two bottoms and the bottom of the 20 crack slots 36 of the upper ring seat are also affected by the M394823 tension hole 37. Deformation continues In addition, it can also provide the backsight visual force after the deformation disappears, so as to ensure that the open shape of the bottom surface 33 of the sleeve is deformed and restored. Before the deformation and the deformation, the sleeve 30 is displaced through the pair of mechanical arms. The outer edge of the upper ring seat 20 (such as the first __

Then, the pair of mechanical arms are moved in the direction of the push-drying P and are separated from the sleeve 30 (as shown in the imaginary line portion in the twenty-ninth figure), that is, the assembly work of the creative covering sleeve in the syringe 1 is completed ( As shown in the thirtieth map). In the steps a and b, the diameter of the inner ring of the lower ring seat 10 and the upper ring seat 2〇 is the same as the outer diameter of the sleeve 3〇, so that they can be statically matched (transition called or tightness). With the interference, there is no displacement, and the glue can also be used to increase the solid strength between them. 'Furthermore' the assembly of steps a to d above can be imported into the existing automatic special mechanical equipment to achieve Therefore, it is very suitable for the safety syringe system 12 M394823 process of mass production.
