  • the core components of the invention of the present application, such as the action of a rotary stopper is highly modified.
  • Conventional filter syringes can be classified into two types. One is a separate suction tube with a built-in filter at the end of the needle, and a separate filter structure that prevents debris from flowing through the needle by inhaling the injection solution and then removing the suction tube. The other is a filter in the syringe. It is a flow filter structure that prevents the debris powder remaining in the suction filter from mixing into the discharge pipe by making the fluid flow type so that when the injection liquid pressure action direction is different from each other during the suction and discharge process, it also changes the internal flow path of the filter unit.
  • the prior application discloses the needle in such a manner that the suction tube disposed next to the needle for discharging the injection liquid and the suction portion including the suction tube cover the needle portion and turn it to tear it off. If the conventional detachable filter was used to cover the end of the needle with a filter module, it was extremely inconvenient and difficult to insert the intake into the glass ampoule. Decreased.

  • an object of the present invention is to propose an easy and convenient opening structure which lowers the probability of a user's mistake of operation by solving the derived technical problems neatly and displaying a more intuitive and familiar operation feeling in the removal process of the suction unit.
  • a thick body rotary stopper 14 with improved sealing performance and operational reliability was applied instead of the conventional flat plate rotating plate cap, which was rather thin. Accordingly, the stopper rotating space 13 was also considered in consideration of the assembly process of the mass production type product. In addition to the shape that can easily insert the thick rotary plug 14 in the lateral direction and fix the rotating shaft, a shape for improving the sealing performance and increasing the reliability of the plug rotation was applied.
  • the suction stopper rotates only by rotating the lower end of the suction pipe.
  • the suction part, the suction pipe, the rotary stopper, etc. the major difference is that the core components can coaxially rotate.
  • the rotary stopper 14 of the present invention which is much thicker by the unique filter-internal molding method, is coupled with the outer protrusion 14-3 of the plug and the receiving groove 23 at the maximum moment radius, so that the rotational force is the first application. It is incomparably strong and accurate compared to. This sufficiently surpasses the frictional force due to the interference between the upper and lower sides of the rotary stopper, thereby increasing the elastic deformation limit of the rotary stopper 14, thereby improving the assembling ability to be assembled in the lateral direction, and also improving the sealing force to prevent leakage of the injection liquid before and after rotation. You will get
  • the suction unit 20 does not need to be modified at all unlike the prior invention, but if necessary, the suction tube may be slightly bent in the injection process or may be slightly twisted in the operation of the rotary stopper 14. It can be made of a soft, non-toxic plastic material. For example, soft transparent polyethylene or polyvinyl chloride material used as a cap material of a syringe or various sanitary containers may be used.
  • the suction part 20 is balanced in strength and flexibility of the material to be convenient to use and harmless to the human body, and preferably, the stopper protrusion accommodating groove 23 part, the needle part coupling groove 24, and the suction pipe 21. Areas that require precise stop after rotation, such as), need to have a more rigid structure. Such areas can be designed to be hardly deformed by increasing the cross-sectional thickness of the same material.
  • parts that do not need to be deformed, but do not require structural strength are made thinner so that they are not broken and bent or twisted, so as not to injure hands during use.
  • the suction part becomes relatively flexible and very transparent at the portion formed to a thickness of less than 2 mm, helping the user's intuitive operation, the needle and the internal rotation stopper when the thickness is more than 2 mm, and While supporting the suction tube well, the rubber ampoule membrane has sufficient strength and hardness to penetrate.
  • the suction tube 21 of the present invention having a cross-sectional shape similar to the crescent shape is not long and has a thin outline. It can be easily adapted to both narrow glass ampoule bottle caps and rubber membrane ampoule lids, as well as the unique shape of the needle half-buried to prevent the mistake of being stabbed in the human body without removing the suction tube after inhaling the injection solution.
  • the injection liquid in the ampoule is introduced into the syringe cylinder in a filtered state.
  • the rotary stopper 14 after closing the inlet hole 16 or after opening the outflow pipe to the needle 11 It can be maintained in a state that prevents the reverse rotation (a thicker rotary stopper to further increase the elasticity of the upper and lower surfaces of the stopper, thereby causing the contact surface between the rotary stopper 14 and the stopper rotation space 13 as much as desired). Designed with proper friction is always maintained.
  • the present invention in addition to the implementation of filter needles that completely block the possibility of impurities such as debris powder is injected into the human body, in addition to solving the disadvantages that the manufacturing of parts by industrial mass production or low-cost process is difficult, as well as in the rotation process Eliminating the need for unnatural deformations of the core components improves the material's freedom of choice, ease of molding, ease of operation and operational reliability.
  • the stopper outer protrusion 14-3 and the outer protrusion receiving groove 23 are coupled in driving at the maximum moment radial position, the rotational force of the rotary stopper 14 is incomparably strong and accurate compared to the prior application. Therefore, by intentionally strengthening the interference fitting assembly state of the upper and lower rotary stopper, the sealing force improvement effect is prevented even when the pressure is increased by the syringe piston. It completely solves the leak problem.
