However, the above techniques are directed to a gun-type automatic injection device having a handle, and there is a problem in that the distance between the handle and the needle (needle) is too long to precisely control the penetration depth and position of the injection needle.

In addition, according to the scanning method, the operation of sucking and injecting requires both hands to be used. Therefore, there is a problem in that the position of the tip of the needle can be moved by the operation of using both hands while the needle is inserted into the skin (or skeleton) .

In order to solve this problem, an automatic syringe is disclosed in Patent Publication No. 10-1377987.

The needle holder 2 and the needle 4 of the syringe 1 are stably held by the needle holder holder 120 and the needle holder 130 so that the tip of the needle 4 is inserted It can be guided accurately to the position where it should be.

The driving unit 200 is installed on the body 100 and slides the flange 3a of the syringe 1 to draw the plunger 3 out of the cylinder 2 by a suction operation, So that the plunger 3 is pushed into the cylinder 2 by an injection operation so that the injection liquid is discharged to the outside of the cylinder 2 through the needle 4 .

The driving unit 200 includes a driving motor 210, a gear assembly 220, a ball rolling spindle 230, a spindle nut 240, and a flange holder 250.

The driving motor 210 may be a servomotor or a step motor which is configured by a motor capable of forward rotation and reverse rotation and is rotated in accordance with the input of a pulse for accurate position control.

The gear assembly 220 is configured to transmit and receive a rotational force of the driving motor 210 to increase torque, and may include a reduction gear. That is, the number of revolutions generated by the driving motor 210 is decreased, but the torque is increased to rotate the ball rolling spindle 230 connected thereto.

The ball rolling spindle 230 and the spindle nut 240 are configured in the form of a ball screw. That is, the ball screw is composed of a spindle nut 240 rotatably disposed on a ball rolling spindle 230 formed in a spiral direction, and includes a circulation path through which balls are moved between the spindles.

The flange holder 250 is attached to the spindle nut 240 to mount the flange 3a and is slidable in the slot 140 formed in the body 100.

At this time, although not shown in the drawing, a rail may be installed so that the flange holder 250 can slide.

4 is a perspective view of a flange holder applied to a device for automatically injecting an infusion liquid according to the present invention.

4, the flange holder 250 includes a holder body 251 coupled to the spindle nut 240, a holder body 251 rotatably coupled to the holder body 251, A flange groove 253 in which the flange 3a of the syringe 1 is inserted, a first plunger groove 253 formed in the flange grip 252 and in which the plunger 3 is fitted, And a second plunger groove 255 formed in the flange groove 253 and into which the plunger 3 is fitted.

The input signal may include an injection button 301, a suction button 302, an automatic injection button 303, a timer button 303, and the like corresponding to each input signal. A stop button 305, and the like.

The operation of the input signal through the injection button 301 is controlled by operating the drive motor 210 (for example, forward rotation) to push the plunger 3 into the cylinder 2, (2) it is released into the injection liquid to the outside.

The operation of the input signal through the suction button 302 is controlled by operating the drive motor 210 (for example, reversely rotating) to draw the plunger 3 from the cylinder 2, And sucked into the injection liquid through the cylinder 2.

At this time, the injection button 301 and the suction button 302 may be constituted by a push button that contacts only when pressed.

The input signal through the automatic injection button 303 is transmitted to the cylinder 2 through the needle 4 as the plunger 3 is drawn out from the cylinder 2 by operating the drive motor 210 The plunger 3 is pushed into the cylinder 2 to move the plunger 3 to the outside of the cylinder 2 through the needle 4 by driving the drive motor 210 (for example, reverse rotation) To the injection solution.

That is, the operation of the automatic injection button 303 is to inject the injection solution through the "Rigging" process. Here, "ligature" is abbreviation of regurgitation, and when the injection is put into the blood vessel, the plunger of the syringe is pulled out to check whether the syringe needle is located in the blood vessel, and the blood is sucked into the syringe.

Therefore, the user can automatically confirm the "go-go" process through the automatic injection button 303, so that the syringe can be maintained in a state of being inserted into the blood vessel There is an advantage that injections can be injected into the correct site.

The input signal through the timer button 304 operates the plunger 3 to the cylinder 2 by operating the drive motor 210 at a predetermined injection amount (or speed) And discharges it into the injection liquid through the needle 4 and outside the cylinder 2.

In some cases, the injection amount of the injection solution needs to be varied in amount to be injected per hour. Accordingly, injection of the injection solution using the timer button 304 can be uniformly injected per hour as the injection amount set at the set time is gradually injected. In addition, the user can keep the syringe in a fixed state, so that the injection liquid can be injected into the correct site.

Here, the automatic injection button 303 and the timer button 304 may be configured as a push-button that repeats on and off each time the button is pressed.

The stop button 305 is for stopping the injecting operation of the injecting liquid in conjunction with the automatic injection button 303 and the timer button 304 and is an operation performed by interrupting the power supply of the driving unit 200 by pressing Stop.

The driving unit 200 is installed on the body 100 and slides the flange 3a of the syringe 1 to draw the plunger 3 out of the cylinder 2 by a suction operation, So that the plunger 3 is pushed in the cylinder 2 by the pouring operation so that the injection liquid contained in the cylinder 2 is discharged through the needle 4 .

The driving unit 200 includes a driving motor 210, a gear assembly 220, a ball rolling spindle 230, a spindle nut 240, and a flange holder 250.

In addition, a charging port 410 is provided outside the body 100 to supply external power to the power supply unit 400.

The process of attaching the syringe to the automatic injecting apparatus 10 will now be described with reference to FIG.

FIG. 5 is a view illustrating a process of mounting a syringe to a wirelessly-charged injected liquid automatic injecting apparatus according to the present invention.

5, when the flange grip 252 of the flange holder 250 is rotated upward, the cylinder 2 of the syringe 1 is fitted into the cylinder holder 110 ). At this time, the needle holder 2b is guided to the needle holder holder 120, and the needle 4 is guided and fixed to the needle holder 130.

The flange 3a of the syringe 1 is inserted into the flange groove 253 and one selected from the plunger 3 is inserted into the second plunger insertion groove 255. [

5 (a), when the flange grip 252 of the flange holder 250 is pivoted downward, the flange grip 252 is held on the upper side of the flange 3a of the syringe, The plunger 3 is inserted into the first plunger insertion groove 254 and the syringe 1 is mounted (see Fig. 5 (b)).

At this time, when the injection button 301, the suction button 302, the automatic injection button 303, and the timer button 304 are pressed by the user's hand during the installation of the syringe 1 in the automatic injection device 10, Can be unintentionally driven.

Accordingly, the automatic injection device 10 may be provided with the intermittent portion 260 to prevent unintentional button operation before the syringe is fully mounted.

Before describing the intermittent portion 260, the ball screw will be described.

6 is a cross-sectional view of a flange holder applied to a device for automatically injecting an infusion liquid according to the present invention.

The ball screw is composed of a spindle nut 240 rotatably disposed on a ball rolling spindle 230 formed in a spiral direction and includes a circulation path 242 through which a ball 241 moves between spindles. The spindle nut 240 includes a circulation path 242 for transferring the ball 241 forward and backward so that the spindle nut 240 is moved in accordance with the rotation of the ball rolling spindle 230, The ball 241 is circulated through the circulation path 242 along the moving direction of the spindle nut 240.

The intermittent portion 260 interrupts the ball 241 circulated through the circulation passage 242 in accordance with the rotation position of the flange grip 252. As shown in FIG 6, 261, a second lever 262, a turning gear 263, and an elastic spring 264. [

The first lever 261 is configured to be able to move up and down inside the flange holder 250, and a rack is provided on one side.

The second lever 262 is configured to be able to move up and down within the flange holder 250 in correspondence with the first lever 261. A portion of the upper portion of the lever 262 protrudes outside the flange holder 250, A rack facing the rack of the first lever 261 is provided.

The direction changing gear 263 is installed between the rack of the first lever 261 and the rack of the second lever 262 and is connected to the first lever 262 in a direction opposite to the moving direction of the second lever 262 261).

The elastic spring 264 elastically supports the second lever 262 in the upper direction.

According to the configuration of the intermittent portion 260, when the flange grip 252 rotates downward and presses the upper portion of the second lever 262, the second lever 262 moves downward The first lever 261 is raised by the rotation of the direction switching gear 263 and the circulation path 242 is opened by the rise of the first lever 261 (See Fig. 6 (a)), so that the ball 241 can circulate through the circulation path 242. [ Accordingly, the ball rolling spindle 230 becomes rotatable.

In contrast, when the flange grip 252 is rotated upward to release the pressing state of the upper portion of the second lever 262, the second lever 262 is moved upwards by the elastic spring 264, The first lever 261 is lowered by the rotation of the direction switching gear 263 and the circulation path 242 is closed by the descent of the first lever 261 (See FIG. 6 (b)), and the ball 241 can not circulate through the circulation path 242. [ As a result, the ball rolling spindle 230 is in an unrotatable state.

The driving part 200 can be driven only when the flange grip 252 is rotated downward to catch the flange 3a of the syringe 1, It is possible to prevent the driving unit 200 from being driven.
