The main body 1 can select the injection amount of the drug from 0.001 cc to 0.1 cc by touch operation of the screen 1a and can select the depth of the needle from 1.0 mm to 3.0 mm, It can be adjusted.

In addition, the procedure mode and speed can be selected according to the patient's condition and procedure, and the procedure mode can be selected in Continuous mode and Nappage mode. The Slow mode, Normal mode, ), And fast (Fast), and it has 100 ~ 220V, 50 ~ 60Hz freely output module.

On the other hand, the gun 2 is provided with an injector holder 22 in which a syringe containing a drug is fitted and fixed on the upper side of the gun, and a piston rod of the syringe is forcibly pushed to the rear side of the injector holder 22, And the end pusher 25 is coupled to the feed screw (not shown) provided inside the body of the gun 2 so as to be interlocked with the feed screw, And the forward and reverse rotation of the conveying screw is made by the mode setting by the touch operation of the main body 1. Further, After the needle of the injector mounted on the injector holder 22 is removed, a pin having a plurality of needles is inserted so that the drug filled in the injector can be injected through the plurality of needles of the pin. When the drug is injected through the plurality of needles of the pin, blood is drawn out. At this time, the blood is sent to the main body through the hose connected to the pin, and the blood sent to the main body is filtered through the filter inside the main body.

However, such a conventional automatic medicine injecting apparatus is configured such that an injection holder to which a syringe is fixed is fixed to a gun and can not move its position, so that the syringe is held and fixed at a position where the syringe can be stably supported and fixed according to the size of the syringe. As a result, there is a problem that the instability of the syringe fixation and support causes the inefficiency of the operation.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

In general, the automatic medicine injecting apparatus comprises a main body 1 for selecting and operating a mode by a touch operation of a screen 1a as shown in Fig. 1, and a main body 1 connected to the main body 1, And the gun 2 is constituted by an injector holder 22 capable of fixing the syringe 100 on the upper front side of the gun body 21 and an injector holder 22 on the rear side of the injector holder 22 And an end pusher 25 for pushing the piston rod 100a of the syringe by pressing the irradiation button 24 formed on the handle 23 of the gun 2. The end pusher 25 is provided on the end of the end pusher 25, Is reciprocally coupled to a conveying screw provided inside the key body 21, and is configured to be able to be moved back and forth by forward and reverse rotation of the conveying screw.

2 and 3, a guiding tip 4 is provided at the distal end of the gun 2 to stabilize the pin 3 by the guiding tip 4, The pin 3 and the guide tip 4 are separated from each other by the partition wall and the discharge port 46 is formed on the lower side of the guide tip 4 so that the blood and the drug And the filter 5 can be detachably attached to the gun 2, thereby facilitating the replacement of the filter and ensuring the simplicity of the filter and providing a faster filtering function. The filter 5 is detachably coupled to one side of the key body 21 and has one side connected to a discharge port 46 of the guide tip 4 by a hose h, (H) to the hose (1).

3, the jig J according to the present invention is slidably inserted into a groove 100b formed along the longitudinal direction of the upper end of the gun 2, as shown in FIG. 3, Respectively. 4 to 6, the jig J is formed by a jig body 110 slidably fitted in and fixed to the groove 100b of the gun 2, Shaped body corresponding to the rectangular shape. The feed screw 120 penetrates the side surface of the jig body 110. The feed screw 120 has a left screw part 121 and a right screw part 122 formed at one side and the other side. When the conveying screw 120 is divided into the left-hand thread 121 and the right thread 122, when the conveying screw 120 rotates, the fastening part 121 and the right- Are transported in directions opposite to each other. That is, each of the fasteners is moved in a linear motion while being widened and narrowed.

A handle 130 is provided at one side of the conveying screw 120 to rotate the conveying screw 120 by rotating the handle 130 and a fastener 140 So that the jig body 110 can be fixed to or released from the key 2 by tightening force. The grip portion 150 is provided on the feed screw 120 so as to directly fix the syringe 100 on the feed screw 120. The grip portion 150 includes a left hand thread portion 121 of the feed screw 120, A pair of fixing jaws A 151a and a fixing jaw B 151b are screwed together like a nut and the fixing jaw A 151a and the fixing jaw B 151b have the same shape As shown in FIG. At this time, a stopper A (151a) and a fixed stop B (151b) are provided on the lower sides of the fixing jaws 151a and 151b, respectively, 152a and a stopper B 152b are formed. The coupling between the fixing jaws A 151a and the fixing jaws B 151b with respect to the left screw 121 and the right screw 122 of the conveying screw 120 is the same as the coupling parts A and 153a shown in FIG. And a fastening portion B (153b).

In the present invention configured as described above, first, the jig body 110 is inserted into the groove 100b of the key 2. Then, the jig body 110 is slid to a desired position, and then fixed at a determined position by tightening the tightening tool 140 provided at one side of the jig body 110. Then the handle 130 is turned to one side to open the fixing jaws 151a and 151b and then the syringe 100 is sandwiched between the fixing jaws 151a and 151b, The jig J can be fixed from the key 2 by turning the handle 130 in the opposite direction so that the fixing jaw A 151a and the fixing jaw B 151b are narrowed to each other. When the syringe 100 is to be replaced only, the handle 130 is turned to open the fixing jaws A 151a and the fixing jaws B 151b, So that it can be replaced.

In this embodiment, the jig body is slid in the groove of the gun so that the jig body can be moved forward and backward. The jig body is fixed at a position determined by the tightening tool, and a pair of fixing jaws A and jaws When the syringe is attached to the gun, the position is moved according to the size and the length of the syringe, so that the syringe can be more stably fixed and supported. So that the body can be attached to and detached from the gun, and the syringe can be mounted, which makes it possible to further improve the ease of use, the accuracy and efficiency of the operation.

Although the automatic injecting apparatus of the present invention has been described in detail above, it should be understood that the present invention is not limited thereto, and the range of the automatic injecting apparatus is determined by the appended claims Is limited. It will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the spirit and scope of the invention.
