Description

Insulin Patch Controller having Battery State Display and Alarm Functions

The present invention relates to an insulin patch wearing device using a current, and particularly, an insulin patch mounted on the insulin patch wearing device and having a battery state display function for displaying a battery state and an alarm function for alarming according to the battery state. It relates to a controller.

Diabetic patients need to be given artificially produced insulin periodically 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 within a relatively short time, are widely used.

Transdermal administration of insulin by injection has the advantage of being able to 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 view of such a problem, a patch-type transdermal administration method capable of administering insulin into the body without using a syringe has been widely practiced by attaching a patch having an insulin layer formed on the skin. In particular, 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, Patent No. 134151, published in Korean Patent Publication, discloses a patch body having a gel-like insulin, a patch plate for applying a current to insulin, and a patch circuit and a closed circuit in direct contact with the skin. Insulin patches have been proposed which consist of a power supply for supplying ground and patch plates. Such an insulin patch is intended to increase the body's absorption rate of insulin by ionizing the gel insulin to penetrate the skin by the applied current.

In the insulin patch wearing apparatus for administering insulin by the aforementioned patch-type transdermal administration method, the insulin patch controller controls whether insulin is properly administered to the user. As an example of an insulin patch controller that informs a diabetic patient that insulin is being properly administered, FIG. 1 discloses an insulin patch controller for effectively administering insulin using a timer. As shown in Fig. 1, the timer 102 operates simultaneously with insulin infusion. As the timer 102 operates, the oscillator 104 outputs a pulse of several Khz. Accordingly, the load drive 106 is operated to drive the insulin injecting device contacting the skin, that is, the load 112, so that the corresponding insulin is injected into the body for a predetermined time set by the timer 102. At this time, the current sensor 108 is installed on the load drive 106 side for operating the load 112 to detect the current. In this case, when the load driving current is detected, the LED display unit 110 is driven to visually identify the current injection state of the user.

However, the conventional technique shown in FIG. 1 has a problem in that the user cannot know the malfunction of the patch controller and the discontinuation of insulin due to the exhaustion of the battery.

Therefore, an object of the present invention can check the administration state of the insulin and the state of consumption of the battery, and also generate an alarm when the battery consumption falls below the set reference value, it can sound an alarm so that the user can take a predetermined action There is provided an insulin patch controller having a battery status indication and an alarm function.

Figure 2 is a block diagram of an insulin patch controller with a battery status display and alarm function according to the present invention.

Hereinafter, a preferred embodiment of the insulin patch controller according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a view schematically showing an insulin patch controller having a battery status display and an alarm function according to the present invention. As shown in FIG. 2, when the patch plate 200 is inserted, a minute current flows through the skin of the user positioned between the patch plate 200 and the conductive rubber plate 216 by the battery 202. This minute current is sensed by the current sensor 208. The current sensor 208 provides the microcomputer 206 with the fact that the minute current is detected. The microcomputer 206 displays the fact that the microcomputer flows in the display unit 210. This indication will allow the user to know that insulin is currently being administered. In addition, the microcomputer 206 outputs a pulse of a predetermined frequency (eg, 2 KHz) to the inverter 214 due to the fact of current sensing provided from the current sensor 208. In this case, the inverter 214 receives a constant DC current provided from the current sensor 208 and converts it into AC and allows the converted AC to be provided to the conductive rubber plate 216 so that ionized insulin can be more efficiently administered to the skin. To help.
