Description

[0001] The present invention relates to a multi-function pen-type injector,

The present invention is directed to a method for the treatment and prophylaxis of diabetic neuropathy by administering a physician's prescription for therapeutic purposes such as insulin injection of a diabetic or injection of a growth hormone of the adolescent, treatment of other arthritis, treatment of asthma and allergic diseases, (Needle) which is used in a disposable manner in combination with a pen-type syringe for receiving a variety of injections as described above, which is used for dosing the user, After use, the front needle of the used pen needle is completely bent by using the cover of the pen type syringe so that it can not be reused, and it can be easily separated, safely discharged and conveniently disposable. The present invention relates to a multifunctional lid of a pen type syringe,
More particularly, the present invention relates to a pen type syringe which accommodates a variety of injection medicines, which are used versatically according to various therapeutic purposes, The components of the present invention are formed into one package so that the front needle of the pen needle is completely bent by the insertion pressure of the user according to the constitution of the present invention packaged by inserting the once used pen needle into the lid for the purpose of scanning The pen-type syringe and the pen needle are inserted 2 ~ 4 times in the left side by using the rotating lever inside the lid by using the rotary lever provided on the outside of the top of the cover, making it impossible to re- And the pen needle which is completely bent is pulled out from the pushbars And can easily and easily discharge the lid out of the lid in a one-touch manner by means of one-touch operation.

Pen-type syringes are easily carried and used when regular injections of a fixed dose such as insulin injections of diabetics, injections of growth hormones of growing adolescents, other asthmatics, allergies, atopic patients, and infertile women injection These pen-type syringes are made for the convenience of various users who need self-injection frequently, such as diabetics themselves.
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, And needles to self-administered daily by the patient himself.
The pen type syringe contains an injection medicament which can be injected several times to several tens of times, and a certain amount of injected medicament can be injected into the human body by pressing.
In addition, the pen needle used in combination with the pen type syringe is a one-time product that is used by replacing the needle every time of use due to the risk of infection or the like. The pen needle is a needlelike needle according to ISO 11608-2, Needle Container, Needle Shield, Needle Tube, and Sterilization Closure Seal are all used as disposable consumables. Especially, among the components, It is collectively referred to as a pen needle in which the injection needle penetrates through the center of the hub and is integrated.
In detail, the needle fixedly attached to the center of the pen needle is considerably thinner and sharper than the needle of a general medical syringe, and the length of the needle is usually as short as 12 mm in consideration of the skin thickness of the user and the thickness of the subcutaneous fat Manufactured, manufactured and used.

On the other hand, in order for the user to self-administer the injection drug, the spiral portion provided on the upper side of the injection drug receptor of the pen type syringe should be inserted into the spiral portion inside the pen needle, The helical part of the upper part of the receptor and the helical part of the inner end of the pen needle are formed by rotating the pen type syringe body 2 ~ 4 times in the left direction with the pen type syringe with the right hand while holding the pen needle with the left hand from the first contact point of the two helices. The pen type syringe is rotated two to four times in the right direction. In this case, the pen type syringe and the pen needle attached to the needle are combined, I was stabbed on the animal's epidermis and then injected with the prescribed injection of pen needle and pen When removing the syringe body has been by way of two to four times a reverse rotation as opposed to left or right direction and the coupling at each separated by unscrewing manner.
However, in the related art, since the receptacle for accommodating the pen needle is fixedly mounted inside the lid and integrally formed with the lid, when the user tightens the pen needle and the pen type syringe by the above- When the pen needle and the pen type syringe are separated by the screw loosening rotation operation after self injection, the pen type syringe is rotated in the right turning direction by holding the cover with the left hand to attempt to separate the pen needle and the syringe body, Type syringe with the right hand and with the left hand rotating the cover in the left-handed direction, the pen needle and the syringe body can not be separated from each other,
When the hand which tries to separate and rotate the pen needle by the user unknowingly grasps the lid to generate the separation and rotational force, and when the separation type rotational force is generated by holding the pen type syringe body, It may be a forward direction or a reverse direction. In such a case, it is often attempted to select the wrong rotation direction for separating the pen needle, and the rotational motion for separating the pen needle is mistaken by the user, The rod-like projections formed inside the receptacle housing the pen needle arranged inside the lid and the rod-shaped projections formed on the outer wall of the pen needle are engaged with each other in the staggered butt state to prevent the pen needle from rotating together with the receiver, Each of the rod-shaped projections having a plurality of projections Which is formed on the upper part of the pen needle, which is not only worn out or dulled by the reverse rotation, but also has an inherent function of each protrusion, The formed threads are also disintegrated or worn away by the reverse rotational force, so that unlike disposable pen needles, the remaining injected medicines contained in the pen type syringe must be used occasionally or occasionally, and the thread of the receptacle is broken, The injectable medicament is scattered to the outside or leaks out due to the administration pressure when the injection is administered, resulting in a problem that the function is lost.
In addition, in the prior art, the cover or main body of the pen type syringe could be applied only to the plastic injection, and the pen type syringe made of a metallic material such as stainless steel, iron, aluminum, tungsten, In the process of separating the pen needle inside the cover by using the cover which is not applicable and opaque material, there is no way to check the inside of the cover, so that the number of threads is different for each manufacturer, It is difficult to determine the number of rotations of the pen type syringe, so that the user tries to rotate the number of rotations to an excessive number of rotations, so that the projections of the thread and the rod are crushed or the number of rotations is smaller than the number of threads, A pen-type syringe may be used So that the user has the inconvenience of attempting the separation process again to separate the less separated pen needles.
On the other hand, there is no provision to limit the specifications and shape of the number and size of the internal thread of the pen type syringe and lid and pen needle, but the overall appearance of the pen needle, which is a disposable consumable item, Since the pen needle products of each manufacturer have overall uniformity and compatibility, it is necessary to standardize the size and shape of the rotating body accommodating the pen needles and the length and shape of the push rod, This provides a starting point for the technology that enables the packaging and disassembling function of a single used pen needle to be packaged.
The present invention is a multifunctional cover for a pen-type syringe, which is composed of a package and functions for discharging the function of being completely and safely separated from the inside of the lid by using a pen type syringe and a lid constituting one set, Needle separation mechanism is not necessary, and moreover, it is safe and easy to see through visual confirmation. Once the pen needle is separated from the pen needle, the pen needle which is released easily and conveniently is formed by the sharp tip of the front needle located at the center of the pen needle and the body The pen type syringe body is irregularly and completely bended and wrinkled by the insertion pressure of the pen type syringe body of the user, so that secondary infection by skin contact or piercing due to user's intention or carelessness is fundamentally prevented,
The pen-type syringe which is used as a versatile pen, and the separate space of the cover which makes up the set is used as a package. The present invention is limited to a circular cylindrical type functional cover which is capable of rotating the lid itself to separate and discharge the pen needle therein, The shape of the lower end of the cover may be rounded like a wavy shape, or any other shape including a shape of an oval, a polygon, and a meteorological shape may be formed in the space formed in the inside of the cover, Remove the pen needle from the inner rotating body and push the A multifunctional lid of a pen-type syringe in which each of the above components is set as one package so as to be discharged through a push button has not been developed yet.
