Description

Insulin patch device

The present invention relates to a device for wearing an insulin patch using an electric current, and more particularly, it is convenient to wear and can be worn well, and it is possible to confirm the administration state of the insulin and the consumption state of the battery, as well as to accurately administer the appropriate amount of insulin at a scheduled time. It relates to a device for wearing an insulin patch.

Patients with diabetes have to be given regular, artificially produced insulin because insulin is not secreted from the pancreas. If the right amount of insulin is not administered in a timely manner, the blood glucose level in the body may increase rapidly and may have a fatal effect on the human body.

Methods of administering insulin into the body include oral administration (약물 口 投 與) method of administering the drug through the mouth, and transdermal administration (經 皮 投 與) method of administering the drug through injection. In general, transdermal administration methods by injection, which can be expected to have a quick effect in a relatively short time, are widely used.

On the other hand, the method of transdermal administration of insulin by injection has the advantage that it can achieve a quick effect in a short time, but has the disadvantage that the patient must bear the pain of inserting the needle into the skin. This pain does not end once but is another challenge for diabetics because it must be experienced each time insulin is administered.

In recent years, in view of such a problem, a patch-type transdermal administration method capable of administering insulin into the body without using a syringe by attaching a patch having an insulin layer formed on the skin has been widely practiced. In particular, recently, a patch-type transdermal administration method using a current has been developed and used to maximize the absorption of insulin in the body. As an example, Korean Patent No. 134151 has a patch main body having insulin in a gel state, a patch plate for applying a current to insulin, and a ground plate which directly contacts the skin to form the patch plate and a closed circuit, and a patch. Insulin patches have been proposed that consist of a power supply that powers the plate.

The insulin patch is to increase the absorption rate of insulin in the body by ionizing the gel insulin by injecting the gel state by the current applied in the state attached to the pretreated skin through an attachment means such as a bandage.

On the other hand, such a conventional insulin patch has the advantage of increasing the absorption rate of insulin in the body by ionizing the gel insulin in the skin by ionization, but a separate attachment means such as bandages should be used to attach the patch body to the skin. There was a disadvantage. This problem adds to the hassle and inconvenience of diabetics who have to take insulin regularly. Of course, the patch may be attached to the skin of the human body for a long time using a bandage or the like, which not only looks unsightly but also causes another problem that the patient wearing it must endure frustration and discomfort.

In addition, the conventional insulin patch is difficult to check the current state of administration of insulin, especially since there is no separate device for checking whether the power is properly applied to the patch plate, or whether the ground plate and skin is properly contacted, especially the built-in battery It is also difficult to check whether the consumption of the. In addition, the dosage of insulin should always be constant. For this purpose, the conventional insulin patch has a problem in that the patient needs to check the dosage by measuring the time after operating the patch.

Therefore, there is an urgent need for the development of an insulin patch device that is convenient to wear and not inconvenient to wear for a long time, and can confirm the administration state of insulin and the consumption state of the battery, as well as to conveniently administer an appropriate amount of insulin.

On the other hand, according to such a request, the present inventors have an insulin patch that can be worn on the wrist at the end of each experiment and research, and by providing a watch function to the patch, it is convenient to wear and has a good feeling of wearing, and the state of insulin administration and battery In addition to being able to check the depletion status of the insulin patch action device that can easily administer a small amount of insulin at a scheduled time.

Accordingly, an object of the present invention is to provide an insulin patch wearing device that is convenient to wear and has a good feeling of wearing.

Another object of the present invention to provide an insulin patch wearing apparatus that can check the state of insulin administration and the consumption of the battery.

It is another object of the present invention to provide an insulin patch wearing apparatus which can accurately administer a suitable amount of insulin at a scheduled time.
