Description

Medical syringe set, High pressable syringe parts and lock up accessories for anti-separation needle to syringe}

The present invention is a device for separation and separation of the needle fastened to the syringe and a syringe article set for ease of use at high pressure discharge, more specifically, the separation between the needle and the needle manufactured by using a synthetic resin usable for medical use And a needle anti-rotation holder to prevent separation, a needle fixing device which is dually fastened over a needle that is fastened to a syringe in which a fixed device is previously formed, and a pain relief applied to a user's hand when the pressure of the syringe is pressed at high pressure. The present invention relates to a syringe grip, an intake grip, and an intake including a grip for ease of use.

Generally, a syringe contains a liquid or gel-like substance to be used in a cylinder in a syringe for the purpose of inhaling or injecting a drug or blood, body fluid, etc. from the human body, or injecting the blood into a human body for the purpose of examination or removal. Or for the purpose of inhaling body fluids from the human body.

In addition, the needle is used for the same purpose as the syringe, and the tip of the needle tube is sharply processed to connect the body to the body when connecting and injecting the body to facilitate infiltration between the syringe and the human body. Penetrating is a generally standardized disposable intended to alleviate pain and facilitate penetration.

Conventional methods of connecting these syringes and needles include a drug outlet 101 of the syringe, that is, a tape at the end of the syringe barrel and a needle 102 of the syringe, that is, a synthetic resin, which fits into the syringe taper. The cylindrical connection, which is inclined inwardly, is fastened and used in a physical fit form to enable this. At this time, since the needle diameter of the needle is smaller than the outer diameter of the tip of the syringe barrel, it has been performed to discharge or inject a low concentration of a general chemical solution, and currently occupies most of the purpose of the chemical liquid injection.

However, when injecting with a high viscosity medicine, or a high viscosity material such as medical high viscosity material or auto fat graft, which is not a general medicine, in order to discharge the material through the needle, it is necessary to apply excessive pressure to the intake (plunger, push rod). High positive pressure is generated inside the syringe barrel, causing the needle to escape from the tapered portion of the syringe barrel or bounce off at high speed.

This phenomenon causes the failure of the original injection and infusion procedure itself, and if the needle is released from the syringe barrel or bounces rapidly at the time of penetration into the tissue, it causes secondary trauma to the patient. This may result in trauma to the person in charge, or damage to the device or device by colliding with another device or device.

Luer lok tip syringe (BD, Corp.) (FIG. 2), which is currently developed and produced and sold by BD in the USA, is prevented to prevent the detachment of the needle as described above. There is a Luerlock pre-filled syringe (glass syringe) (FIG. 3), and a Korean patent 20-0435652 "Medical syringe set, medical syringe and removable needle holding device" (FIG. 4.) has been invented. These devices are provided with a screw-type fixing device 201 in the syringe barrel in the case of a Luerlock tip syringe is integrated with the syringe barrel through injection or rotational injection, core type injection method at the time of production of the syringe barrel, and rotates the needle 202. Induced to screw the luer lock tip portion 201 (Fig. 2.), Luerlock pre-filled syringe (glass syringe) (Fig. After screwing the luer lock holder 301 in the form of a fitting, the needle 302 was rotated to screw the luer lock holder 301 (FIG. 3). , Medical syringe and removable needle fixing device "to fasten the screw fixing device 401 to the syringe barrel 406 with the irregularities in some modified injection method (Fig. 4.) so as not to significantly interfere with the conventional syringe barrel production. One After the needle 402 was rotated to prevent the departure of the needle by a screw fastening method to the fixing device 401.

However, the results of repeated experiments to inject high-viscosity materials in order to inject other high-viscosity materials in order to invent other technical developments of the present inventors to achieve the present invention (Plunger, push rod) with high force to inject high-viscosity materials {(104, 204 , 304, 404)} high positive pressure is generated inside the syringe barrel, the needle that is fastened in the screw type does not withstand the positive pressure and rotates in reverse to escape from the syringe. In addition, when the intake (plunger, push rod) is pushed at high pressure to discharge the contents of high viscosity, the intake force (plunger, push rod) is bent and the external force that is pressurized does not have a straightness and is dispersed, and the force on the intake (plunger, push rod) The area of the part giving pressure to the intake (plunger, push rod) {(105, 205, 305, 405) by hand is small and causes pain in the user's hand. The supporting portion (103, 203, 303, 403) has a size much smaller than the finger area, which gives the user more strength in support and causes fatigue and pain. Therefore, the conventional solution to the injection of a material having a low viscosity was not unreasonable, but a fundamental solution for injecting a high viscosity material did not solve the domestic patent "medical syringe set, medical syringe and removable needle holding device" This includes the hassle of modifying or separately producing standardized syringes, which currently dominate the market.

The present invention relates to a fixing device for firmly fixing a needle to a medical syringe, and a high viscosity material, such as fat used for fat transplantation, a polymer material for repairing soft tissue, etc., is inserted into the syringe and then discharged from the syringe to the outside. Since the needle is discharged from the inside of the syringe barrel through a narrow needle, it provides a needle holding device for preventing the needle from being ejected or bounced off by the high positive pressure generated at this time, and a set of convenience syringe supplies for applying high pressure. There is a purpose.

The present invention does not deform the special syringe barrel that is already mass-produced or sold in small quantities and sold without using a conventional syringe as it is, the injection and scattering of the needle that occurs when injecting high viscosity chemicals and substances An object of the present invention is to provide a fastening device that can be fastened easily.

In addition, the purpose is to enable economical reuse by replacing or detachable in the case of syringe barrel and needle that can be reused depending on the use.

In order to achieve the purpose of injecting the high-viscosity material to prevent the escape of the needle and flying out of the needle in the present invention, the intake (Plunger, specially invented to apply a high pressure to discharge the high-viscosity material from the syringe through the needle) Push rod) grip and the suction sucker (plunger, push rod) including the grip, the syringe grip to strongly support the syringe barrel with a finger to push the intake (plunger, push rod), and the needle for preventing needle departure It is a syringe kit set consisting of a needle holder that is removable and reusable.

In detail, when the pressure is applied to a high pressure, positive pressure is applied to the inside of the syringe barrel, and a needle locking anti-rotation holder having a locking part is formed to prevent the needle that is rotated from being ejected or bounced out by the pressure, and a luer lock holder or a luer lock tip. When using a syringe, it provides a needle fixing device for double fixation on the outside of the needle, and it is simple to handle and intake (plunger, pusher) of the syringe barrel to prevent the pain given to the user's hand when providing high pressure and to provide convenience. The present invention solves the problem by inventing a grip (handle) and a suction absorber (plunger, push rod) in which the grip is integrated to enable a fastening. Syringe and needle compatible with the present invention is characterized in that it is used as it is without improving the existing syringe and needle as a standard product already mass produced.

The present invention prevents the needle from rotating back by pressure by rotating the needle fixing device in a double rotation to the syringe after the standardized needle is rotated to the syringe in which the Luer lock is formed or the Luer lock holder is added.

In addition, by inserting the injection reverse rotation prevention holder with the anti-rotation tab in place of the existing luer lock holder to the pre-filled syringe produced so that the luer lock holder can be fastened. Prevented.

In addition, the syringe grip and intake grip (plunger, push rod) can be replaced by a simple fastening of the existing syringe or a sucker with a grip. It prevents the user's pain caused by the small size and the area of the hand to be touched, the inconvenience of applying more force than necessary, and the intake (plunger, push rod) bending under pressure.
