Definitions
- the present invention relates to an injection needle having a filtering suction structure and a filter syringe employing the same.
- Glass ampoules which are often used as injectable containers, generate fine glass fragments when the bottleneck is broken and opened. This debris, which is invisible but incorporated into the injection solution when the ampoule is opened, can remain inside the cylinder and needle (hereinafter referred to as the needle) and enter the body during the injection process.
- filter syringes can be divided into two categories. One of them is a separate suction tube with a built-in filter at the end of the needle. The suction filter is sucked and then the suction tube is removed to remove debris from the needle. It is a flow filter structure inside the syringe which prevents the debris powder remaining in the filter from entering the discharge pipe. It is designed to change the internal flow path of the filter unit by changing the pressure direction acting differently during the suction and discharge of the injection liquid. .
- the latter fluid filter structure is a filter structure that has recently attracted attention, and various derivative models have been patented and registered competitively.
- the filter flow according to the change of the pressure direction acting on the fluid inside the needle is changed. It adopts a common design structure to change.
- Syringes with this technology are easy to use as they do not differ in appearance from ordinary syringes without filters.
- both suction and discharge must be done with one needle, so that during the suction, when debris is completely passed through the needle and does not flow deeply into the filter inner channel but remains between the needle and the outer channel of the filter, subsequent discharge, that is, injection
- the problem is that debris powder can retreat back to the needle and enter the human body.
- the object of the present invention is to comprehensively solve the disadvantages of the two conventional filter syringes as described above.
- the first operating condition is to maintain the inherent advantages of the conventional detachable suction tube.
- the suction tube 21, which is completely separated from the injection needle, is disposed together with the needle 11 to separately inject the injection liquid.
- the injection needle is designed to prevent glass fragments from entering the source.
- the suction tube 21 is shaped to a thickness and length exceeding the minimum of the size of the needle 11 to be almost completely compatible with the existing ampoule. Place them adjacently (with virtually needles included).
- the present invention should be able to easily separate the suction tube and the needle without holding the needle so that the needle does not contaminate when removing the suction tube before the injection.
- the suction part 20 including the suction pipe is configured to completely wrap the needle part 10 including the needle.
- the suction part 20 including the suction pipe 21 may be made of a soft non-toxic plastic material that may be bent or twisted.
- soft transparent polyethylene or polyvinyl chloride material used as a cap material of a syringe or various sanitary containers may be used.
- a material having a balance in strength and flexibility is basically adopted, but the structurally required portion of the suction part 20 is designed to be cut to compensate for hardening instead of securing a certain thickness of the cross section. Also, parts that should not be cut but do not require structural strength are made thinner so that they can be flexibly deformed.
- the suction part becomes very flexible and transparent at a part formed within a thickness of 1 mm to help the user's intuitive operation, and when the thickness exceeds 2 mm, the needle and the inner flow stopper structure
- the rubber ampoule membrane is well supported and has sufficient strength and hardness to penetrate.
- the suction unit 20 may show excessive operation that greatly deviates from the initial engagement state with the adjacent needle by the appropriate cross-sectional thickness change according to the site and the arrangement of the intentional and appropriate incision groove 26 intended accordingly.
- the tip of the suction pipe 21 is preferably applied with a material sufficiently hard to penetrate the ampoule plug of the rubber membrane type and to protect the tip of the needle.
- the suction pipe 21 and the filter 15 are connected to one pipe line, and the suction pipe 21 is exposed to expose the needle 11 after the injection liquid introduced into the cylinder through the pipe line is completed. After removing the filter, the pipe and the filter 15 disposed in the pipe are actually open. Even if there is a separate injection liquid discharge needle 11 in this state, it is natural that the injection liquid in the cylinder is simultaneously ejected to the filter 15 and the needle 11 when the syringe piston is pressed.
- the filter 15 side pipe line should be designed as a one-way permeable pipe line that is capable of inhalation but blocks the discharge until at least a complete closure is made.
- the conventional technique commonly used in these conditions is a flexible membrane.
- the rubber membrane that bends in only one direction in the opening manner is positioned between the filter and the syringe cylinder to open only to the cylinder, the injection liquid is only sucked through the filter and is not discharged.
- the unidirectional valve is opened and air can be introduced into the open filter, and the introduced air can enter the cylinder and enter the human body as it is through the needle.
- the conventional unidirectional valve structure is difficult to use in the field of filter syringes to which the present invention belongs.
- most commercially available syringes with a fluid filter structure (described above) can also be sucked slightly while the needle is plugged in to check for blood inflow. May be injected into the human body.
- the present invention contemplated a kinematic structure in which the inlet hole of the filter 15 described above is closed by the operation accompanying the incision and detachment process of the suction unit 20 after the suction is completed in the initial fully open state.
- disposable needles are not large parts that are easy to design mechanically, nor are they precision parts.
- the overall structure is required to have a simple and robust and reliable sealing structure.
- an operation opening and closing mechanism is provided that provides convenience of operation while maintaining structural simplicity and sealing reliability close to existing disposable needles. That is the rotary plate stopper 14 and the peripheral configuration that is linked to the incision and detachment operation of the suction unit 20.
- the rotary plate stopper 14 may be made of the same material as the suction part 20 as a thin strip-shaped soft member, but may selectively use a human silicone material having excellent softness and elasticity to further enhance sealing force. have.
- connection tube 24 formed on the inner circumferential surface of the suction unit 20 is slightly lodged in the inlet hole 16 of the needle unit 10 and is connected to the connection tube 24 when it is separated from the side. It can be seen that the rotary plate stopper 14 closes the inlet hole 16 while rotating in the rotary plate storage unit 13 formed on the support 12 of the needle.
- a simple and reliable actuating stopper is realized utilizing the characteristics of the soft elastic material, and the rotary plate stopper 14 completes the filter closing role and then disengages rotation of the entire inlet 20 beyond the predetermined range.
- the coupling state with the connecting tube 24 may be properly released as necessary to prevent breakage or rupture by movement.
- the filter needle is implemented to completely block the possibility that impurities such as debris powder is injected into the human body, in particular, the outer diameter of the separate suction pipe is limited to about 3 ⁇ 6mm close to the needle outer diameter, and the length of the suction pipe also slightly exceeds the needle length This makes it easy to use compact filter needles that can easily be used in virtually any injection ampoule without special attention from the user.
- FIG. 1 is a view showing the filter needle and the filter syringe of the present invention as a whole.
- Figure 2 is a view showing the filter needle coupled to the syringe cylinder with or without the cap.
- FIG 3 is an exploded view showing the main part of the filter needle.
- FIG. 4 is a perspective view and a cross-sectional view of the overall structure of the filter needle.
- FIG. 5 is a view showing a state immediately before prescription in which the needle is exposed by sliding the suction unit 20 after completing the injection of the injection.
- the filtering needle presented in the drawings and the detailed description may be largely divided into three technical parts, namely, the needle part 10, the suction part 20, and the cap 30.
- the filter needle composed of 3 parts occupies most of the technical scope of the present invention and may be an independent product in itself.
- the filter syringe configured by detachably or fixedly equipping the filter needle is also included in the technical concept of the present invention as the invention of the same category.

- a cutout groove 26 is formed on the side of the suction part 20, and the cutout groove extends to almost the end of the portion surrounding the needle 11 over the entire extension portion 22, preferably in a spiral shape.
- the total pitch number (twist number) of the helical cut groove is shown as one in the embodiment of the figure, but may be formed in two to three if necessary.
- the finger touches the needle part 10 so as to contaminate it. There is also an increased risk of compromise, so compromise with the proper twist.
- the place for accommodating the needle 11 and the suction pipe 21 for sucking the injection liquid are separated from each other.
- the suction pipe 21 to be discharged onto the needle 11 does not need to be cut as long as it can rotate about the needle 11 and does not need an incision groove.
- the end of the suction unit 20, that is, the end of the suction tube 21 is preferably in the shape of a needle (with some degree of hardness) having a cross-sectional thickness so as to penetrate the ampoule plug made of rubber membrane as necessary.
