Description

[0001] Apparatus for injecting medicine [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug infusion device, and more particularly, to a drug infusion device capable of improving the convenience of the procedure during manual infusion of an infusion solution by allowing a practitioner to more easily and comfortably hold the device.

Implant refers to a replacement that restores when the original tissue is lost, but it refers to a series of procedures that implanted an artificial tooth.

In dentistry, the implant is replaced by a fixture made of titanium or the like, which has no rejection to the human body, so that it can be substituted for the lost root (root). The tooth is implanted into the alveolar bone, To restore the function of the patient.

Such an implant procedure may vary depending on the type of fixture, but it is also possible to use a predetermined drill to puncture the placement position, fix the fixture to the alveolar bone to perform an osseointegration on the bone, and then attach the abutment to the fixture, Of the final prosthesis.

In normal prostheses or dentures, the surrounding teeth and bones are damaged over time. However, since the implants do not injure the surrounding tooth structure and have the same function and shape as the natural teeth and do not have cavities, they can be used semi-permanently.

In addition, the implant procedure improves the function of the denture in single-tooth restorations, as well as partial and total toothless teeth, improves the aesthetic aspects of dental prosthesis restoration, and further distributes excessive stress on the surrounding supporting bone tissue It helps to stabilize the dentition as well as sikim.

On the other hand, the implantation procedure causes a lot of pain to the recipient by performing the incision of the gums and the drilling by the drill during the procedure. Therefore, local anesthesia for the implant site is essential.

Such local anesthesia is usually performed by injecting an anesthetic liquid into a treatment site by pressurizing an anesthetic liquid with a syringe. At this time, if the injection speed of the anesthetic liquid, that is, the pressure speed of the anesthetic liquid is fast, excessive pressure is generated at the injection site of the anesthetic liquid, and the painter feels pain.

Therefore, injection of the anesthetic liquid should be done as slowly as possible. However, if the injection rate of the anesthetic fluid is slowed down, the injection time of the anesthetic fluid is increased, and the time required for the operator to hold the syringe is increased.

If the time the operator is holding the syringe is increased, it is not only difficult for the practitioner to maintain a constant infusion rate, but also a hand shake may occur. As a result, the patient is required to have a long time to open the mouth, and furthermore, the shaking motion of the operator causes the sufferer to feel the pain.

Many attempts have been made to solve these problems, and an automatic anesthesia apparatus as disclosed in Korean Patent No. 10-0784931 has been developed as a representative example thereof.

The automatic anesthesia device has an advantage that the injection speed of the anesthetic liquid can be appropriately adjusted according to the change in the pressure formed at the site to be treated, thereby minimizing the pain felt by the patient.

However, the conventional drug injecting apparatus having the above structure has a disadvantage in that the structure of the drug injecting apparatus is complicated and heavy, which makes it difficult for a practitioner to hold for a long time, and additional pain due to a hand- .

On the other hand, since local anesthesia induces pain when the anesthetic fluid enters the blood vessel, the injection needle is inserted before injecting the anesthetic liquid, and the syringe plunger is slightly pulled back so that the needle is not penetrated through the blood vessel Depending on the sensitivity of the patient or the degree of anesthesia, it may be more convenient to inject the anesthetic fluid manually by the operator under the judgment of the operator, rather than injecting it automatically.

However, as described above, the automatic anesthesia devices according to the related art are complicated in structure and heavy, making it difficult for the practitioner to handle for a long time, and there is a problem that the anesthetic liquid can not be injected by manually switching them as needed.

Accordingly, the present applicant has registered the patent application for the last drug injection device.

The drug injector previously registered by the present applicant is both manual and automatic so that convenience is enhanced and the injection time is reduced by selecting the injection method according to the sensitivity of the patient so that the patient's satisfaction can be improved, It is reported that patients are receiving good evaluation.

However, this time, the practitioner is able to grasp the device more easily and comfortably, thereby leading to the proposal of a drug injection device having an improved structure for improving the convenience of the procedure when manually injecting a drug (injection).

When the plunger pressing handle 151 is pushed, the pair of finger holders 152 have an arc shape so that the fingers can be disposed and support the force. The thumb can be inserted into the plunger pressing handle 151 in a state where the detection and stop are arranged in the pair of finger holders 152 and the injection liquid can be manually injected while pressing as shown in Figs.

Of course, unlike the drawing, the pair of finger holders 152 may be foldably applied. In this case, the pair of finger hitches 152 may be folded in the automatic mode.

The automatic injecting unit 160 is selectively connected to the plunger 140 in the dry type grip housing 110 and automatically pressurizes the plunger 140 by the power to automatically inject the injected liquid into the treatment area .

As described above, since the manual mode by the manual injection unit 150 and the automatic mode by the injection unit automatic injection unit 160 are selected and determined by the practitioner, the automatic injection unit 160 injects the dry type gripping housing 110, Lt; RTI ID = 0.0 > 140 < / RTI >

The automatic injecting unit 160 includes a motor 161 that generates power for pressing the plunger 140, a worm gear 162 that is coupled to the rotating shaft of the motor 161, And may include a rack gear 163 that meshes with the worm gear 162.

The motor 161 generates power for automatically pressing the plunger 140 in the automatic mode operation as shown in Figs. 8 and 9, as described above. (Not shown) may be operated by a battery in the housing 110. [

An input button 113 for a motor for selecting and inputting the rotational speed of the motor 161 is provided on one side of the dry type grip housing 110. The speed of the motor 161 can be set to be faster each time the motor input button 113 is pressed. As the speed of the motor 161 increases, the injection amount per unit time of the injection liquid may increase.

In this embodiment, the input button 113 for the motor is formed as a single button but the input button 113 for the motor is provided as a sensor on one side of the dry type grip housing 110 to form the dry type grip housing 110 A structure may be applied in which the amount of injection is automatically adjusted by the pressure to be gripped.

A battery remaining amount indicator 114 may be provided around the input button 113 for the motor. The battery remaining amount display unit 114 displays the remaining amount of the battery applied to the motor 161. [ The display method at this time may be an alarm method.

The worm gear 162 constituting the automatic injecting section 160 is connected to the motor 161 and the rack gear 163 is formed at one side of the plunger 140. Therefore, when the worm gear 162 is rotated by the motor 161, the worm gear 162 and the rack gear 163 engaged with the gear can linearly move, and the plunger 140 can be moved to pressurize the injection liquid have.

At this time, gear engagement between the worm gear 162 and the rack gear 163 is performed through the cut-out portion 142 formed on one side of the plunger casing 141. That is, the worm gear 162 can be engaged with the rack gear 163 exposed to the cutout 142 area.

On the other hand, in order to select the automatic mode as shown in Figs. 8 and 9, or the manual mode as shown in Figs. 11 and 12, a drug injection device 170 according to the present embodiment is provided.

In other words, the injector injection selecting unit 170 plays a role of selecting the injection of the injection fluid to be operated in one of a manual mode by the injection fluid injecting unit 150 or an automatic mode by the automatic injecting unit 160 . The injecting liquid injection selecting unit 170 may include a injecting liquid injection selecting knob 171 and a gear driving unit 180.

The injector injection select knob 171 is rotatably coupled to the outer surface of the dry type gripper housing 110 and serves to select one of the injector injector 150 or the injector automatic injector 160.

2, a manual mode by the injection fluid injection unit 150 or an automatic mode by the automatic injection unit 160 by rotating the injection fluid injection selection knob 171 coupled to the outer surface of the dry type phage housing 110, Can be selected. 2 corresponds to the automatic mode.

The worm gear 162 is connected to the rack gear 163 on the basis of the rotation operation of the injection liquid injection selection knob 171. The worm gear 162 is connected to the injection liquid selection knob 171, Selectively engaging or disengaging the gear.

8 and 9, when the injection injection selecting knob 171 is rotated in the lateral direction, the worm gear 162 is meshed with the rack gear 163 and the automatic mode by the automatic injector 160 proceeds .

When the injector injection knob 171 is rotated obliquely as shown in FIGS. 11 and 12, since the worm gear 162 is disengaged from the rack gear 163, the manual mode by the injector manual injection unit 150 can proceed have.

A knob rotation restricting portion 190 is provided around the injection liquid selection knob 171. The knob rotation restricting portion 190 serves to restrain any rotation of the injection liquid selection knob 171. That is, it prevents the manual mode and the automatic mode from being arbitrarily selected without the intention of the practitioner.

The gear driving unit 180 includes a motor supporting rotating body 181 that supports the motor 161 and is rotatable together with the motor 161 and the worm gear 162, A hinge 182 for rotatably connecting the dry type gripping housing 110 and a protruding pin 183 protruding from the motor supporting rotating body 181 and one end of the protruding pin 183 being engaged with the protruding pin 183 And the other side may include a rotary member 184 connected to the injection liquid injection selection knob 171 and rotated together with the injection liquid selection knob 171.

At this time, the rotation member 184 is formed with a locking groove portion 185 which is engaged with the projecting pin 183. The locking groove portion 185 forms a position where the locking groove 181 is engaged with the projecting pin 183 in the manual mode, A manual mode section 185a and an automatic mode section 185b connected to the manual mode section 185a and forming a position where the protrusion pin 183 is caught in the automatic mode.

10, when the injection liquid injection selection knob 171 is rotated, the rotary member 184 is rotated to forcibly pull the projecting pin 183 so that the projecting pin 183 is placed in the manual mode section 185a Whereby the motor support rotating body 181 is rotated by the hinge 182 to rotate the motor 161 and the worm gear 162 together. Then, the worm gear 162 can be separated from the rack gear 163 as shown in FIG. 13, so that the manual mode by the injection liquid injection unit 150 can proceed.

Hereinafter, the operation of the drug infusion device according to the present embodiment will be described.

In order to use the drug infusion apparatus according to the present embodiment in the manual mode, the injection infusion selection knob 171 is rotated obliquely as shown in FIGS.

When the injection liquid injection selection knob 171 is rotated, the rotary member 184 is rotated to forcibly pull the projecting pin 183 so that the projecting pin 183 can be disposed in the passive mode section 185a. The motor support rotating body 181 is rotated obliquely by the hinge 182. As a result,

When the motor supporting rotating body 181 is rotated obliquely by the hinge 182, the motor 161 and the worm gear 162 coupled to the motor supporting rotating body 181 are also rotated together with the motor supporting rotating body 181, So that the worm gear 162 can be separated from the rack gear 163.

When the worm gear 162 is separated from the rack gear 163 and the detection and stop are disposed on the pair of finger holders 152 constituting the injection liquid injection unit 150, And the injection liquid can be injected manually while pushing the plunger pressing handle 151. At this time, the injection rate of the injection liquid can be arbitrarily adjusted by the operator.

Meanwhile, in order to use the drug injection device according to the present embodiment in the automatic mode, the injection liquid injection selection knob 171 is rotated to be in the horizontal direction as shown in FIGS.

The worm gear 162 can be engaged with the rack gear 163 by the reverse operation of the gear driving unit 180 described above.

When the worm gear 162 is rotated by the motor 161 while the worm gear 162 is engaged with the rack gear 163 and the motor 161 is operated to rotate the worm gear 162, The plunger 163 can move linearly, and thus the plunger 140 can be moved to pressurize the injection liquid. Therefore, the injection liquid can be injected automatically.

In such an automatic mode, since the injection liquid can be injected into the treatment site while automatically pushing the plunger 140 by the power of the motor 161, the operator does not feel the pain.

If the patient's anesthesia progresses to such an extent that the pain can not be felt to a great extent, the user may press the motor input button 113 to quickly adjust the automatic injection rate, or switch to the manual mode to quickly inject the remaining injection fluid.

According to the present embodiment having the above-described structure and function, the operator can more easily and comfortably hold the device, thereby improving the convenience of the procedure upon manual injection of the injection liquid (drug).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention.
