Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pen-type syringe having a one-touch coupling and detachable pen needle and a one- be disposed by one-touch operation}

The present invention relates to a method for the treatment and prophylaxis of diabetic retinopathy by administering insulin as an autologous insulin or as an injection of a growth hormone for the adolescents, treatment of other arthritis, treatment of asthma and allergic diseases, A pen needle having a needle (injection needle) used in a single use in combination with a pen type syringe used for various purposes as described above,

The user inserts the pen needle by one-touch inserting method and injects the pen needle by one-touch method using the inside of the cover of the pen type syringe, and the user inserts the front needle of the pen needle by the insertion pressure of the syringe body Pen type syringe with ability to completely bend to make it impossible to reuse and at the same time to separate the pen needle and pen type syringe and to easily dispose of the separated pen needle with one-touch method The present invention relates to a pen needle having a one-touch coupling and a detachable wing-like support and a lid having a one-touch discharge function,

More particularly, the present invention relates to a pen type syringe which is used for various purposes as described above and accommodates a variety of injection medicines according to a therapeutic purpose, The present invention can be applied to a needle-bending function through a bending contact plate and a separating and discharging function, so that the pen needle, which is fastened to the upper thread of the injection medicine receiver of the pen type syringe once used for self- When the pen needle is inserted together with the pen type syringe, the front needle of the pen needle is completely bent by the insertion pressure of the user due to the constituent inside the lid, thereby making it impossible to reuse the pen needle as a one-

At the same time, the upper wing-like support of the pen needle completely wrinkled inside the lid is made to be linearly separated from the inside of the lid only by the self-elasticity of the pen-type syringe in the inside of the lid, The present invention relates to a method for safely disposing a pen needle which is once used as a one-touch discharge method by a push button on the upper outer side and is completely wrinkled in a state in which the front needle is completely wrinkled.

Pen-type syringes are used to inject infusions of injectable medicines regularly in doses of injections such as insulin injections of diabetics, injection of growth hormones of growing adolescents, patients with asthma, patients with arthritis, allergies, atopic patients, infertile women, Such a pen type syringe is made for the convenience of the user who needs to self-scan frequently by himself as described above.

Insulin is indispensable and must be administered to patients with type 1 diabetes, especially type 1 diabetes. Methods such as inhaled, patch, and oral forms of insulin have been developed and studied, The pen type syringe generally contains an injection medicament which can be injected several times to several tens of times, and a certain amount of the injection medicament can be injected into the human body by pushbutton .

In addition, the pen needle used in combination with the pen type syringe is a one-time product which is used by replacing the needle every time of use due to the risk of infection or the like, and the pen needle is a needle hub in accordance with ISO 11608-2, Needle Container, Needle Shield, Needle Tube, and Sterilization Closure Seal are all constituted as one set. The components are all one-time consumables, Needle Hub, which is equipped with a needle inserted through the center of the hub, is called a pen needle.

In detail, the needle fixedly attached to the center of the pen needle is considerably thinner and sharper than the needle attached to a general medical syringe, and the length of the needle is usually 12 mm And it has the characteristics that it is manufactured, produced and used very briefly.

Meanwhile, in order for the user to self-administer the injection medicament, the spiral portion provided on the upper side of the injection medicine receptacle of the pen type syringe is removed from the inner side spiral portion of the pen needle contained in the large- And the helical part of the upper end of the pen type syringe receptacle and the inner end of the pen needle should be pivoted by the pen needle at the first hand point of the two spirals and the pen type syringe at the right hand , The pen type syringe body is rotated 2 to 4 times in the leftward direction to connect the pen type syringe body by a screw fastening method,

On the contrary, by holding the pen needle with the right hand and rotating the pen type syringe 2 ~ 4 times in the right direction, the pen needle and the pen needle are combined using the large cap, When the pen needle and the pen type syringe main body are separated from each other, the cap is put back on the pen needle used in the opposite direction of the above-mentioned connection, or a separate cover inside Or inserted into a separate separating mechanism, and rotated counterclockwise or counterclockwise two to four times to separate them in a screw loosening manner.

However, conventionally, when the user injects the self-injection, first, the sterilization finish seal at the lower end of the needle container is removed, and then the thread formed in the needle hub and the tip of the injection medicine receiver The pen needle and the pen type syringe are connected and fastened by performing the screw fastening method by the rotational movement for insertion as described above for the fastening of the thread formed on the needle, A procedure involving a rotational motion in which a needle is pushed onto the skin by a user and the needle is automatically injected in a state where a needle is pulled out from a hub by separating and removing a needle needles from a needle hub However,

As described above, when the pen needle and the syringe main body are combined by the rotary type fastening method using the screw as described above and the user injects the injection agent, when the pen needle used once in the pen type syringe is separated, There is a structural problem that a separating action by a rotary motion, that is, a screw releasing system in the reverse rotation direction by the number of revolutions or the number of revolutions exceeded at the time of engaging is necessarily required.

That is, conventionally, there is a problem that when the pen needle is fastened to or separated from the pen type syringe, it must be absolutely dependent on the method and procedure of the coupling and separation through the rotational movement by the thread, Also, there is a structural problem in that the separation process must be performed by using a large-cap or separate rotary separating mechanism.

Therefore, in the conventional method, with respect to the pen needle used by the user, when the hand attempting to separate and rotate is unconsciously put on the cover of the pen type syringe or the single used pen needle in the large cap, The direction of separation rotation may be a forward direction for separating the pen needle or a reverse direction for separating the pen needle from the pen needle, In this case, it is often the case that an attempt is made to select the wrong direction of rotation for the rotation.

On the other hand, when the pen needle is rotationally moved for separating the pen needle and is in the same direction as when the user accidentally fastens the pen needle, the rod-shaped protrusion formed inside the receptacle for accommodating the pen needle formed inside the large cap or the cover, The rod-shaped protrusions are engaged in the staggered butt state to prevent the pen needle from rotating together with the receptacle, so that each of the rod-like protrusions having a supporting force against the rotational force is worn by the user for such a wrong reverse rotation Not only will the inherent mutual support function of each projection be lost,

The thread on the upper end of the pen type syringe, which is fastened to the upper inner thread of the pen needle, which is directly transmitted with excessive rotational force, is also broken or worn by the reverse rotation force of the upper end of the receptor of the pen type syringe. Unlike pen-type syringes, pen-type syringes need to be used several times or several times until the remaining amount of the syringes is consumed. However, since the thread of the pen-type syringes receiver is disrupted, There is a problem that the injection solution is scattered or leaks out of the skin due to the administration pressure when the injection is administered again, resulting in the loss of the function.

Therefore, the present invention can be used to make a pen needle, which is used once inside the lid, with a pen type syringe and a lid constituting one set, to be completely bent so as to make contact with the skin from the needle of a user intentionally or carelessly, A function of preventing the unnecessary pain caused by piercing or the like and preventing the risk of the secondary infection caused by this is provided, and it is possible to use the one time only by the linear motion by the one-touch push button without going through the separation process, A functional cover that separates and discharges completely worn pen needles easily, completely and safely,

A pen needle for one-time use having a shape and structure capable of a one-touch insertion and fastening function instead of a screw fastening method by a conventional rotary motion when the pen needle is fastened to a pen type syringe for self-injection administration Pen needles and covers have not yet been developed that combine the one-touch insertion of the pen needle and the one-touch needle bend and separate ejection functions after synchronicity.

The pen-type syringe is connected to the tip of the pen needle which is seated in the large cap. When the linear insertion pressure is applied to the inside, a space considering the width of the spreading support wing is repeated so that the wing-shaped support formed on the pen needle by the pitch and height of the thread and thread is pushed and then folded again. Is provided on the inner wall surface, and the lower end of the large cap is compressed and packed with sterilization paper EO gas or the like.

The small cap and the large cap are formed in a plurality of openings having a uniform spacing on the outer circumferential surface of the cylindrical peripheral portion so as to facilitate separation and removal of the small cap or large cap in a linear direction.

Meanwhile, the lid for separating and discharging the pen-tip equipped with the plurality of wing-shaped supporters once used by the user for self-injection administration by one-touch separation using a lid that forms a set with the pen-type syringe is composed of a lid body, A button, and a contact plate for pushing a bar, a spring, and a needle.

The clip body has a through-hole to receive and receive a push button and a push rod at an upper portion thereof. The clip body has a plurality of wings of a pen needle to be inserted by a user's insertion pressure into the lid, And a cylindrical support member for supporting the upper end of the wing-shaped support member in contact with the upper end of the support member. The wing-shaped support member is suspended by the self-elasticity of the pen needle to the cylindrical member, The thread formed on the upper end of the receptor is disconnected from the thread formed in the pen needle and is naturally separated from the pen needle.

When the push button is not used due to the spring received in the space inside the upper portion of the clip body, the push button is always raised to the upper part by the tension of the spring, and the pen needle used once is separated from the cover and discharged The needle is vertically lowered by the pressing pressure of the user and the pen needle is completely separated and discharged from the cylinder located at the center of the clip body. Then, the pen needle is returned to the upper end of the clip body and the push button constitutes the lower end portion and the lower end portion is used once A cylindrical space and a groove are provided in which a body for contact-plate for bending the needle is inserted and fixedly coupled to the front needle of the pen needle to completely bend the front needle of the pen needle by the insertion pressure of the user, And the body for contact plate for bending the needle, The plate body is caught by the inner jaw of the cylindrical body of the clip body and is no longer pushed to the upper portion, so that the push button and the pushing rod that accommodate the spring can not be pulled out to the outside of the clip body, As shown in Fig.
