Abstract

PROBLEM TO BE SOLVED: To provide an insulin injector for inhibiting a person who suffers diabetes and takes an insulin shot from forgetting that the insulin shot has been already taken and erroneously taking the shot twice before meal.SOLUTION: Circuit components such as a cell (or a piezoelectric element), a capacitor (an electric storage element), and an LED (a light emitting diode) are incorporated into an injection button. By depressing an insulin injection button with a thumb in taking the shot, the incorporated LED is lit and performs display for a fixed time, and thus a user can determine that he/she has already taken an insulin shot.

Description

The present invention relates to an insulin injector.

In the present invention, when injecting insulin before meals for the treatment of diabetes, forgetting that it has already been injected and inadvertently injecting insulin twice, it causes hypoglycemic symptoms and causes unconsciousness or worst-case situations. It was invented to prevent things from happening in advance.

The most important challenge for those who need insulin injections for the treatment of diabetes is to make two incorrect insulin injections before a meal.
That is, it is wondering whether or not insulin has already been injected at the stage of eating a meal, and performing a second erroneous injection.
In order to prevent the second injection, it is a problem to develop a syringe that can display that the syringe has been injected for a certain period of time by the action of insulin injection. In addition, fixed time refers to the time from injecting to taking a meal.

Means for solving the above problems will be described with reference to a use state diagram of the pen-type insulin syringe shown in FIG. The insulin syringe is used by injecting a prescribed amount of insulin by pressing the insulin injection button (1) with the thumb. However, since there is no record of the injected action, it may happen that the user is confused by whether or not the injection has been completed. In the present invention, in order to leave the injected action as a record, the present invention solves this problem by adding a function of emitting light to the insulin syringe for a predetermined time by pressing the injection button (1).

As stated in the above problem section, two incorrect injections result in twice the prescribed amount of insulin being injected into the body. This leads to a hypoglycemic state and leads to a serious accident related to unconsciousness or worst life, but if the injection indicator shows that the syringe has already been injected, it can be determined that it has already been injected, thus eliminating the above problem. effective.

FIG. 1 is a structural diagram of an injection button light emitting section of a pen-type insulin syringe, showing a use state diagram of the syringe and a detailed enlarged view of an injection button / push button switch section (A) of the syringe. In the enlarged view (1) is an injection button / push button switch of a pen-type insulin syringe, (2) is an LED light emitting element, (3) is a capacitor, (4) is a battery, (5) is a display portion of an insulin injection amount, (6) shows a push button switch lifting spring for securing the contact gap (g) of the push button switch portion. FIG. 2 shows an example of an LED light emission display circuit diagram in an insulin injector, where (1) is a push button switch, (2) is an LED (light emitting diode), (3) is a capacitor (storage element), (4 ) Indicates a battery. FIG. 3 shows an operation chart of LED light emission related components. In this figure, (1) represents the operation of the push button, (2) represents the lighting time of the LED, and (3) represents the change in the charged amount of the capacitor. The horizontal axis represents the elapsed time (t).

An embodiment of the present invention will be described with reference to FIGS.
In the circuit diagram of FIG. 2, the components (2), (3), and (4) are electrically connected in parallel. By turning on the injection button / push button switch of (1), the battery of (4) The LED of (2) emits light and is simultaneously stored in the capacitor of (3). Even if the switch of (1) is released (OFF), the LED continues to be lit until the accumulated power capacity of the capacitor is exhausted.
FIG. 3 is an operation chart showing the operation and timing of each circuit component in FIG. 2 on the time axis. The reference numerals given in FIGS. 1, 2, and 3 represent the same product names.

Claims (3)

Injected by circuit parts such as a battery (or piezoelectric element), capacitor (electric storage element), LED (light emitting element), etc. incorporated in an insulin injection button used for injecting insulin, etc. Insulin syringe having a function of displaying LED lighting for a certain period of time A pen-type insulin injector that can inject insulin into the body at the same time as injecting insulin, and at the same time, feeds the generated power to the capacitor and the LED by the piezoelectric element, and displays the LED for a certain period of time.
