FIG.

1 and 2, a drug injection device according to an embodiment includes a case 10, a driving module 20, a suction adapter 30, an operation switch 40, a controller 50, 60). Here, the suction adapter 30 is configured so that the needle 121 of the needle module 120 installed in the case 10 can be easily inserted into the skin without moving the position so that the syringe 120 is connected to the suction adapter 30 As shown in Fig. When the skin is sucked into the suction adapter 30, the syringe 110 installed in the case 10 is pushed through the driving module 20 to insert the needle into the skin and automatically supply a certain amount of the syringe .

Each configuration of the drug injection device according to the present invention will be described in more detail.

The case 10 is formed as a handgun so that the user can grasp and easily operate the apparatus. The case 10 incorporates a drive module 20, a suction adapter 30, an operation switch 40, and a controller 50 integrally. For reference, the case 10 has an operation button 12 in the form of a trigger for manipulating the user's drug injection device.

The driving module 20 presses the syringe 110 so that the syringe 110 mounted on the case 10 scans a specified amount of drug and is integrally formed in the case 10. [ The specific structure and operation of the driving module 20 will be described below again.

The suction adapter 30 receives the negative pressure from the negative pressure generator 60 independent of the hand-held terminal G and is installed at the muzzle of the case 10 to suck the contact skin during drug injection.

The operation switch 40 switches the drive module 20 in accordance with the operation of the operation button 12.

The controller 50 is disposed at the back of the case 10 so that the user can easily control and confirm the operation of the drug injection device.

The negative pressure generator 60 generates a constant negative pressure according to the setting of the user, and transmits a negative pressure to the suction adapter 30. To this end, the negative pressure generator 60 wirelessly transmits a signal to the controller 50 of the pistol type terminal G, which is independent of the negative pressure generator 60, and a pumping module 61 that pumps air to generate negative pressure, A communication module 62 for opening and closing the pumping module 61 and a valve 63 for maintaining or eliminating the generated negative pressure to open and close the pumping module 61; And a display module 65 for outputting information so that the user can operate the negative pressure generator 60 directly and check the operation status thereof. And a filter 66 for filtering the intake air.

Subsequently, the hand-held terminal G has a light source 70 functioning to sterilize medicines injected into the skin and disinfect the aspirated skin, and a light source 70, which wirelessly communicates with the communication module 62 of the negative pressure generator 60, A communication module 90 for wirelessly transmitting a control signal to the negative pressure generator 60 and a notification module A for informing the user of the scanning time using the handgun type terminal G. [ For reference, the wireless communication between the communication modules 62 and 90 can be performed through a short-range wireless communication technology such as Bluetooth.

The operation sequence of the drug injection device will be described in more detail with reference to FIG.

S10; Step of driving the drug injection device

The user operates the selected one of the input button 51 of the controller 50 and the display module 65 of the negative pressure generator 60 to drive the drive module 20 and the negative pressure generator 60 are prepared for driving. For reference, the control module 64 of the negative pressure generator 60 prepares to drive the pumping module 61 in accordance with the input signal of the display module 65. The control signal of the controller 50 may be wirelessly transmitted through the communication module 90 and may be transmitted to the communication module of the negative pressure generator 60 90 wirelessly receive the control signal and are transmitted to the control module 64. Of course, the control module 64 controls the driving of the pumping module 61 in a process corresponding to the control signal.

S20; Negative pressure generation step

When the user operates the controller 50 to transmit a negative pressure signal, the negative pressure signal is transmitted via the communication module 90 of the hand-held terminal G, and the negative pressure generator 60 wirelessly receives the negative pressure signal Control module 64, and the control module 64 drives the pumping module 61 according to the negative pressure signal.

The pumping module (61) delivers negative pressure to the suction adapter (30) through the hose.

For reference, the suction adapter 30 forces the contact target skin into the suction adapter 30 forcibly.

S30; Drug injection step

When the user operates the operation button 12, the operation button 12 applies pressure to the operation switch 40, and the operation switch 40 switches the drive module 20 to drive. The drive module 20 moves the syringe 110 mounted on the case 10 by a specified amount so that the drug of the syringe 110 is injected through the needle module 120 into the skin.

At this time, since the suction adapter 30 receives the negative pressure of the negative pressure generator 60 and sucks the skin inward, the needle module 120 can always inject a drug by inserting a needle at a predetermined depth into the skin.

S40; Preparation stage of aspiration skin separation

The user must separate the aspirating skin from the suction adapter 30 in order to inject the drug into the other skin, and the generated negative pressure must be stopped. However, when the operation of the pumping module 61 is stopped to stop the operation of the pumping module 61 of the negative pressure generator 60 and to subsequently inject the drug into the neighboring skin, there is a problem that the drug injection time interval becomes too large . Of course, since the drug injection must be performed quickly within a short time, turning on / off the pumping module 61 itself is not preferable for drug injection.

The control module 64 further includes a valve 63 for temporarily losing the negative pressure caused by the pumping module 61. The control module 64 controls the operation of the valve 63 in accordance with the control signal received from the controller 50 do.

Accordingly, when the driving module 20 is stopped after the operation of the operation button 12 by the user, the drug injection is stopped and the control module 64 controls the driving module 20 to stop the driving of the driving module 20 The valve 63 is immediately operated to open the drawing hose of the pumping module 61 and lose the negative pressure. In this embodiment, the valve 63 operates for 1.5 seconds, and the negative pressure is lost to the suction adapter 30 for 1.5 seconds even when the pumping module 61 is being driven.

S50; Aspiration skin separation step

When the negative pressure of the suction adapter 30 is completely lost by the operation of the valve 63, the user can easily remove the suction adapter 30 from the skin. The controller 50 emits a sound or light through the notification module A after a certain period of time after the operation of the valve 63 so that the drug injection device accurately informs the user of the separation timing.

In the present embodiment, the controller 50 causes the notification module A to emit light for 0.5 seconds after 0.6 seconds from the operation of the valve 63. For this purpose, the light emitting means of the LED lamp can be applied to the notification module (A).

The user separates the suction adapter 30 from the skin in accordance with the notification of the notification module (A). Subsequently, the valve 63 stops operating, and the suction hose of the pumping module 61 is closed again so that a negative pressure is generated in the suction adapter 30.

When the suction adapter 30 is removed from the skin, the suction adapter 30 is brought into direct contact with the neighboring skin. At this time, since the pumping module 61 continues to operate, ). The user immediately operates the operation button 12 to inject the drug.
