Description

[0002] Painless injection device [0003]

More particularly, the present invention relates to a non-painless scanning apparatus, and more particularly, to a non-pain-free scanning apparatus, in which a vibration generator and a syringe are integrally formed in a state in which a pain at a site to be scanned is not sensed by using a sound wave or vibration, To an improved non-painted injection device.

Generally, syringes are used to anesthetize or treat sensitive parts such as dental treatment or Botox injections, which are accompanied by severe pain, and research has been conducted to alleviate this.

US Pat. No. 8,449,482 (Mar. 3, 2013) 'Vibrating anesthesia device' discloses a technique related to so-called 'painless injection' in which pain is relieved by injecting a sensitive part in a state of being vibrated at a specific frequency.

However, conventionally, since the means for vibrating a specific frequency and the syringe are separately formed, they are inconvenient for portable use, and there is a high possibility of loss during storage and carrying. There was an inconvenience disadvantage.

Particularly, in hospitals, when two or more hands are used separately for injection prescription (eg Botox injections), it is necessary to use both hands instantaneously. .

In other words, when you hold the vibrator with your left hand and apply vibration, you always have to prepare a syringe, so you have to hold a syringe in your right hand. It would be nice to drop the syringe and do another work with your right hand, but if you drop the syringe, you will have a problem of contamination.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a syringe which is integrally formed with a vibrator so that vibration of the vibrator is not transmitted to a syringe, The present invention has been made to solve the above-mentioned problems occurring in the prior art.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the non-painted injection apparatus according to the present invention includes a vibrator 100.

The vibrator 100 may include a well-known structure disclosed in the U.S. Pat.

Of course, designs such as shapes and shapes can be modified.

A tip 110 is provided at the tip of the vibrator 100 to transmit vibrations well when a scan is performed.

The vibrator 100 is provided at its upper end with a syringe 200. The syringe 200 is connected to the vibrator 100 in a state in which the vibration of the vibrator 100 is not transmitted through the vibration damping means 300, Respectively.

In this case, the syringe 200 is provided in a fixed state such that the needle accurately points at a point where vibration of a specific frequency is applied to the needle 110 in a specific direction, that is, the tip 110, so as not to feel pain.

Therefore, since the injection needle is already fixed, there is no fear that the injection will be applied to a portion that is out of the region where the pain is not felt by the vibration transmitted by the tip 110 during injection preparation.

This is an important concept that prevents physicians from making careless mistakes and making mistakes, so that they can give patients safe and accurate injections without feeling pain.

In particular, an illumination lamp 130 made of an LED is further provided to illuminate the periphery of the injection space so as to guide the injection placement operation more accurately and easily.

As described above, since the syringe 200 is integrally formed with the vibrator 100, when the vibrator 100 is gripped and lifted, the syringe 200 is lifted together. Even if only the vibrator 100 is held with one hand, the syringe 200 is attached together, so that the other hand is not required to hold the syringe 200.

Therefore, when the other hand needs to be used instantaneously, it is not necessary to hold the syringe 200, so that it is possible to freely use other work with the other hand.

Particularly, in the present invention, a vibration unit 120 generating vibration in the vibrator 100 is replaced with a sonic vibrator or a known motor vibrator (a device for causing vibration by rotating the eccentric cam) Feature.

However, the specific configuration of the sonic vibrator will be described later.

Here, the vibration damping means 300 constitutes the most important feature of the present invention. If the vibration damping means 300 is not provided, the vibration of the vibrator 100 is transmitted to the injector 200 as it is during scanning The patient may feel a great deal of pain.

However, in the present invention, such a problem is solved by blocking the vibration of the vibrator 100 through the vibration damping means 300 so as not to transmit the vibration to the syringe 200 at all, and the syringe 200 is integrated with the vibrator 100 have.

More specifically, the vibration damping means 300 includes a vibration damping housing 310, as illustrated in FIGS. 2 and 3.

The vibration damping housing 310 is preferably integrally fixed to the upper surface of the vibrator 100, more preferably, a groove is formed in a part of the upper surface of the vibrator 100 as shown in FIG. 1, It is even better when the installation is done in a stable manner.

In addition, a portion of the upper surface of the vibration damping housing 310 is recessed to have a predetermined depth installation groove 312.

The upper plate 320 is installed in the installation groove 312 and the lower end surface of the upper plate 320 is supported by at least one pair of the sliding guides 330.

The sliding guide 330 is integrally formed with the bottom surface of the installation groove 312 and includes a lower cylindrical guide 332 protruding from the bottom surface and one end fixed to the lower cylindrical guide 332, And an upper cylindrical guide 334 integrally fixed to a lower end surface of the upper plate 320.

In this case, a buffer spring may be provided between the inner bottom surface of the lower cylindrical guide 332 and the lower end surface of the upper cylindrical guide 334 to elastically cushion.

A first cushioning member 340 and a second cushioning member 350 are provided inside the sliding guide 330 to cushion the lower end surface of the upper plate 320 and the bottom surface of the mounting groove 312, Can be installed.

Here, the first and second cushioning members 340 and 350 may be provided alone or in combination.

The first buffer member 340 may be a cylindrical damper 342 as shown in FIG. 3 (a) or a flange-like damper 344 as shown in FIG. 3 (b) It is possible.

The flange type damper 344 includes a top plate UPP and a bottom plate DWP, which are steel plates, and a bottom plate DWP, And a core (COR) vertically connected and fixed to the core (COR). A damping rubber (DPR) having a disk shape and a hole at the center is inserted into the core (COR) An air layer AIR is formed between any one of the damping rubber DPR and the adjacent upper damping rubber DPR by sequentially stacking the damping rubber DPR and the spacer RIN in such a manner that the spacer RIN is seated on the upper damping rubber DPR. .

The damping rubber DPR and the spacer RIN are surrounded and sealed by a cylindrical cover rubber CVR and the upper and lower ends of the cover rubber CVR are connected to the upper plate UPP and the lower plate DWP, .

Therefore, the damping rubber (DPR) laminated with the air layer (AIR) therebetween by the spacer RIN interposed in the transmission of vibration has its own vibration absorbing function. However, since the air layer (AIR) Since the medium changes continuously and repeatedly, the vibration is absorbed and attenuated to completely block the vibration.

In addition, the second cushioning member 350 may be a generally known cushioning member in the form of a spring, more preferably a shock absorber.

As described above, according to the present invention, vibration of the upper plate 320 is absorbed by the sliding guide 330 and the first and second cushioning members 340 and 350, The vibration of the syringe 200 is hardly transmitted to the syringe 200.

On the other hand, an edge damping rubber 360 is installed in the circumferential direction of the upper plate 320.

As shown in FIG. 2, the frame damping rubber 360 may be surrounded by a plurality of piles along the periphery of the upper plate 320. The damping rubber absorbs vibration as in the damping rubber (DPR) (320) vibrates in the front and back and left and right directions, i.e., the X and Y directions, and absorbs the vibration.

In particular, by surrounding a plurality of piles, the vibration waveform transmitted each time the pile is passed rapidly is absorbed in the direction of the plate surface, so that the vibration is almost hidden during the passage of several ply.

In this case, it is needless to say that the multi-ply edge damping rubber 360 may be constructed in the same manner as the internal structure of the flange type damper 344 described above.

A pair of fasteners 370 are provided on the upper surface of the upper plate 320. The fixture 370 encloses the body of the syringe 200. The fixture 370 and the syringe 200 may be formed in a shape that can be combined and separated, or may be integrally formed.

On the other hand, since a known method such as an interference fit method is used for the coupling and separation, a detailed description will be omitted here. In addition, in the case of integral type, it is difficult to separate the syringe 200 from the fixture 370, and the syringe 200 should be capable of moving back and forth in the fixture 370. 3 shows a fixed structure. In FIG. 1, a cover for covering the fixture 370 is further provided for aesthetic appearance.

4 is a perspective view of an ultrasonic vibrator 400 according to an embodiment of the present invention. Referring to FIG. 4, an upper body 420 having a lower body 410 and a lower body 410 covering the upper body 420 is assembled A magnetic body 430 is installed at the center of the lower body 410 and a bobbin 440 is fixed to the upper portion of the magnetic body 430 and a voice coil 450 is wound around the bobbin 440 A cone damper 460 is closely attached to the upper surface of the bobbin 440 and the cone damper 460 is fixed to the upper surface of the bobbin 440 by an operation probe 470.

The cone damper 460 vibrates in the vertical direction due to the magnetic field generated by the interaction between the voice coil 450 and the magnetic body 430. That is, the cone damper 460 vibrates due to the sound source This acts as a vibration of the air, which acts as a speaker to produce sound.

When the sonic vibrator 400 is used, vibrations are generated in response to a change in acoustic pressure of a sound source supplied from the outside, so that it is not a random vibration, so a smooth vibration is possible, It is very useful when applied to the non-painless injection apparatus of the present invention in local anesthesia.

5, when the fixture 370 is fitted and fixed in the circumferential groove 220 formed in the body 210 of the syringe 200, when the vibrator 100 is held with one hand, The body 210 can be moved by the length of the circumferential groove 220 by pressing the syringe flange 230 so that the syringe needle can be inserted into a portion to be syringe within the moving distance.

Therefore, it is not necessary to use both hands to insert the syringe 200, and to provide ease in the operation of one hand.

It should be understood, however, that this is only illustrative of one variant embodiment and is not limited to this configuration.

When the vibrator 100 is held by the vibrator 100 and the tip 110 is placed on a sensitive area to be injected, the position where the syringe needle is to be automatically inserted is determined within the range of no-pain.

In this state, when the body 210 of the syringe 200 is slightly pushed, the body 210 moves and the syringe needle is inserted. Then, the piston 240 is pushed to inject the injection liquid.

Since the vibrator 100 maintains the vibration state during the scanning operation, the sensitive region vibrates at a specific frequency to alleviate the pain, so that even when the injection is performed, the pain is not accompanied.

Therefore, painless injection is possible and effective treatment is possible.
