Description

[0001] The present invention relates to a pen needle safety ejection mechanism,

The present invention relates to the separation and discharge after use of a hub, i.e., a pen needle, which is equipped with a needle (needle) used for disposable use in combination with a pen type syringe used mainly by diabetics who administer insulin, More particularly, the present invention relates to a pen-type syringe, and more particularly, to a pen-type syringe, which is inserted into the inner space of a lid, which is used once, and the pen needle itself is bent or wrinkled by the insertion pressure, Type syringe. The syringe and the pen needle are rotated counterclockwise. The pen needle is easily and safely removed from the lid of the pen type syringe by a one-touch pressure method.

Pen-type syringes are easily carried and used when a regular dose of injectable medication is required, such as insulin administration.

These pen-type syringes are mainly made for the convenience of users who need to inject themselves frequently, such as diabetics.

Insulin is essential and must be administered to people with diabetes, especially type 1 diabetes. Methods of insulin administration have been developed and studied in the form of inhaled, patch, and oral medicines. Still, the usual method of administration is daily administration of the patient using a syringe and a needle.

The pen-type syringe contains a medicament which can be injected several times to several tens of times, and a certain amount of medicament can be injected into the human body by pressing.

The pen needle of the pen-type syringe is a single-use article which is used by replacing the pen needle every time the pen needle is used due to the risk of infection due to injection. The pen needle is a single set of the small cap, the moving body having the irregularities, Consists of.

The pen needle is very thin in thickness, sharpness and relatively short in length compared to a needle of a general medical syringe.

In general, a spiral portion provided at the upper portion of the pen type syringe is used by being inserted into the tip of the innermost spiral portion inside the pen needle. The spiral portion is rotated two to four times from the initial contact point of the two spiral portions, When the needle is inserted into the skin of the human body or animal with the screw of the type syringe and the pen needle fastened together, it is prescribed and injected by the prescribed injection agent, and when the pen type injector and the pen needle are separated after use, The left turn is rotated 2 to 4 times, and each of them is separated in a screw loosening manner to dispose of the used pen needle.

However, in the past, when the disposable pen needle has been used once and then the needle protecting cap has been inserted into the needle in the process of separating the pen type syringe from the used pen needle, the pen needle may be stuck to a very small, Of the pen needle in the direction of the left turn, as well as the case where the pen needle is stuck to the needle by carelessness in the course of attempting the screw release method very frequently.

Furthermore, due to the cumbersome process of safely disposing of the medical waste after separating the pen needle which is once used and contaminated, and the economical problem of repetitive repetition of the pen needle as a one-time consumable item, It is a disposable consumable item, and there is a problem that it is actually reused repeatedly.

Meanwhile, up until now, a disposal container for disposing a disposable pen needle after use has been developed (JP-A-2014-18456, JP-A-9-19498) However, the present invention has a disadvantage in that the disposal container or the separation mechanism must be separately managed. However, the present invention is not limited to the pen type syringe Convenient and safe separation and discharge function according to the one-touch discharge is provided without risk of direct contact with the user's hands or skin against the pen needle which is safely detached from the inside of the lid, thereby eliminating the need for a separate separation mechanism, Since the penile needle is irregularly bent or wrinkled with sharp ends and trunk, Or puncture of the skin due to carelessness, and to prevent secondary infections. Pen needle sorting ejector using the inner space of the cover forming one set with pen type syringe is easy to carry and easy to store Safe and easy to use.

In order to facilitate separation of the pen needle having been used once from the main body of the pen type syringe, the pen type syringe has been used to solve the problem as described in the background art. In order to separate and discharge the pen needle fastened to the space inside the lid by the screw fastening method that rotates the pen tip type syringe to the right side two or three times, again by the reverse rotation (left side) screw releasing method,

The pen needles are entirely wrapped around the inside of the cover and are prevented from rotating in the same direction at the same time, and there is provided a concave / convex portion at the lower end of the movable pen for discharging the pen needle so that the function of bending or crushing the needle inside the lid can be performed. It is composed of a movable plunger and a cover clip for pen needle discharge.

The needles which are engaged with the pen needle on the upper part of the pen type syringe are brought into contact with the irregularities of the movable lower part for discharging the pen needle provided inside the syringe lid, The tip of the needle, which is very sharp by pressure,

Quot; shape or " d " shape, or the like, and thus the reuse is fundamentally impossible.

When the pen needle is separated from the main body of the pen type syringe, the pen needle once used is rotated and fixed to the inside of the lid by rotating it counterclockwise in the counterclockwise direction, So that only the pen needle attached to the crushed needle is left inside the movable body irregularity.

In this way, the pen needle bent by the insertion pressure of pushing the pen type syringe into the lid in a state where the pen type syringe is engaged with the movable body unevenness fixedly mounted inside the lid of the pen type syringe is provided in the upper part inside the lid Using a cover clip connected to the movable plunger for the pen needle discharge, it is pushed out by the one-touch pressure method in the downward direction and discharged from the inside of the cover to the outside of the cover.

When the pen-type syringe and the pen needle are separated from each other after the pen-needle equipped with the needle is once used and the needle-protecting small-cap is inserted into the needle, the user can not insert the pen- It is often the case that the needle is stuck to a very sharp needle due to carelessness, such as when it is stuck or when it is attempted to separate it immediately without putting the small cap on the needle. The pen needle, which is used for one time use to block the contamination due to reuse and repetitive use of the disposable pen needle and the secondary infection caused by it, is used after the pen tip is used once, Needle is separated and discharged so that it can be fundamentally prevented from being used repeatedly as well as reusing

When disposing of used pen needle from a pen type syringe, the tip and body of the needle are completely bent or wrinkled, preventing accidental physical contact or piercing of the needle to prevent instant pain. And to prevent unintended secondary infection such as tetanus.

In order to achieve the above object, the present invention relates to separation and release after use of a disposable pen needle for use in a pen-type syringe for insulin administration for administering insulin for the treatment of diabetes,

The pen type syringe body is equipped with a container containing the injected drug, a scale mark for indicating the amount of use, a push button for injecting the injected medicine into the body, and a spiral part outside the upper end of the pen type syringe to be fastened with the disposable pen needle In addition,

The spiral part is formed of a cover and a form similar to a normal fountain cap lid for protecting the injection medicine and the medicine container when the pen type syringe is not used or stored for everyday, It has a single pen shape.

The lid is opened so that the container for storing the injection medicine of the pen type syringe and the spiral portion of the upper portion can be inserted into the lid, the lid lower end is open and the lid upper end is normally clogged considering the design side. Has a hollow form.

The manufacturing method of the lid of the pen type syringe having the function of separating and discharging the pen needle according to the present invention is not limited to the use of the simple protective lid of the lid of the conventional pen type syringe, A new function is provided to separate the used pen needle easily from the spiral part of the pen type syringe and to discharge the pen needle to the outside of the lid for one-touch pressure method.

In addition, the front needle of the pen needle, which is spirally connected to the pen type syringe through the separation and discharge process, is inserted into the lid by the insertion pressure to insert the pen type syringe into the lid, Since the front needle is completely bent as described above and the worn pen needle is discharged from the inside of the cover to the outside because the front needle is completely bent as described above because it is inserted into the uneven surface of the lower part of the movable bar for the user and is completely bended or wrinkled, And the ability to prevent secondary infection due to physical contact of the tip of the needle, which can be caused by a very sharp needle.

In order to solve the above-mentioned problem, the upper end portion of the lid is formed with a protrusion for supporting a movable bar which prevents the movable plunger for withdrawing the pen needle from retracting, and the side surface of the lid is provided with a movable plunger for discharging the pen needle, And the upper end of the pen needles for discharging the pen needle is connected to the uppermost point of the uppermost point, The pen needle is opened by a length sufficient to reciprocate up and down from the inside of the lid to the outside when the pen needle is released from the inside of the lid for direct downward discharge pressure using the lid clip, On the inner side of the opening of the form, the cover clip and the moving stick An "H" beam-shaped rail is formed which enables reciprocating motion.

The lower end of the lid is completely open to the self-storage of the pen-type syringe and the insertion passage of the pen-type syringe for the separation and ejection of the pen needle used once.

The lower end portion of the movable plunger for discharging the pen needle is constituted by a "convex" shaped pen needle fastened to the upper spiral portion of the pen type syringe, a very thin and thin needle mounted on the center portion thereof, a pen type syringe body through the opening The tip of the front needle is inserted and bent, and the tip of the front needle is bent and wrinkled. Ultimately, the tip of the needle is fixed to the pen needle, And is composed of a plate having concave and convex portions.

In order to separate the pen needle used once from the pen type syringe cover, when the upper part of the pen type syringe is inserted from the lower end of the cover into the inside of the moving object irregularity, the lower part of the movable pen for pen needle discharge moves upward The movable stopper and cover clip for discharging the pen needle discharging pen needle used in proportion to the length of the cap is generated in proportion to the end of the cap top opening portion, After the pen needle is lowered due to the pressing pressure of the cap clip, the upper part of the moving pen for the pen needle discharging is pushed up toward the upper part of the cover by the process of inserting into the cover for storing the pen type syringe main body The upper end of the lid opening comes into contact with the upper end of the lid opening, Rug period shape of the constituent having the unevenness of the one lower end is in contact with the exactly the same as its outer surface and the plunger moves through the lower support surface is structured to maintain the sealing property.

In order to separate the pen-type syringe main body from the pen-type syringe main body, a pen-type needle attached to the upper spiral portion of the pen-type syringe inserted into the lid for separating the pen- In order to prevent the pen needle from being rotated in the same direction with the pen type syringe body in the left direction during separation, a rod-like projection for supporting the pen needle outside is provided. Shaped projections are formed in the moving object irregularities in four to six rooms, so that the rod-like projections on the outer wall surface of the pen needle and the rod- And has a designed structure to be inserted.

In addition, since the pen-type syringe is detached from the inside of the cover after the pen needle is removed by the left-turn unwinding method of the upper spiral portion of the pen-type syringe, The pen needle, which has been bent or wrinkled,

The one-touch discharge pressure directly below the cover clip, which is integral with the pen needle ejection movable plunger, separates it from the rod-shaped projection for supporting the pen needle outside and is eventually discharged from the inside of the cover, The crumpled needle is discharged in the rear position and the pen needle bottom portion containing the rear needle relatively safe for the user is discharged. Therefore, it is possible to separate and discharge the pen needle more safely after use, and it is already curved and wrinkled, Characterized in that it is provided with a function for facilitating the collection and disposal of safe and easy disposable front needles.

As described above, according to the present invention, there is no need to purchase a separate pen needle discharger separately after using the disposable pen needle equipped with the needle in the pen type syringe, and it is possible to easily use the pen needle, And the discharged pen needle is already discharged with the tip and the body of the sharp front needle bent or completely crumpled to thereby prevent the reuse of the pen tip to prevent contamination and secondary infection caused by the reuse of the user, When the pen needle is removed, it is also advantageous to prevent secondary infection due to unexpected physical contact such as needle piercing due to carelessness. Even when the used pen needle is processed, the pen needle can be handled without touching the user's hand at all As well as due to the already completely bent or crumpled pen needle due to the insertion pressure There is also capable of convey processing conveniently disposed of effect.
