One side of the upper housing 100 is provided with a seating portion 115 seated on the body, for example, the penis. The seating portion 115 is screwed to one end of the upper housing 100. Therefore, when the seating portion 115 is rotated clockwise or counterclockwise, the seating portion 115 protrudes and immerses by a predetermined length from the upper housing 100.

One side of the lower housing 200 which is screwed to the upper housing 100 is a second long hole 201 of the a shape is formed. The second long hole 201 prevents the cover member 350 from being separated from the lower housing 200 and performs a locking and unlocking function to prevent the cover member 350 from being pressed due to inadvertent operation. do. That is, when the second lever 355 penetrates through the second long hole 201 and is inserted into the through hole 351 of the cover member 350 fitted into the lower housing 200, the cover member 350 may have a lower housing 200. ) Is not released. At this time, when the second lever 355 is positioned in the second long hole 201 formed in the longitudinal direction of the lower housing, the cover member 350 may be pressed into the lower housing, that is, in an operable state of the injection device of the present invention. When the second lever 355 is positioned in the second long hole 201 formed in the circumferential direction of the lower housing, the cover member 350 cannot be pressed, that is, the injection apparatus of the present invention is in a stopped state. .

One end of the lower housing 200 is fixed to the head 331 of the support pin 330, which will be described later, and at the same time, the support 205 located inside the cover member 350 is integrally formed with the lower housing 200.

A guide groove 202 into which at least one ball 250 to be described later is fitted is formed at the side of the support part 205 in the longitudinal direction of the lower housing 200. The guide groove 202 is formed with an inclined surface (not shown) inclined in the direction of the center axis of the support portion 205 so that the ball 250 is not separated into the support portion 205. By this inclined surface, the ball 250 can move only along the guide groove 202 in the longitudinal direction and the radial direction of the support portion 205 without departing from the inside of the support portion 205. The end portion of the support portion 205 is bent to fix the head 331 of the support pin 330.

The lower housing 200 is provided with pressing means for applying pressure to the syringe housed in the upper housing 100. The pressing means includes a rod member 310 which is installed to be protruded to one end of the lower housing 200, a second spring 320 which elastically biases the rod member 310 in the piston 12 direction, And a holding part for maintaining the second spring 320 in a compressed state.

The rod member 310 is installed to protrude and immerse from the lower housing 200. One end of the rod member 310 is provided with a front end 311 to apply pressure to the piston 12, and the other end is provided with a stepped jaw 313 so as to protrude from the outer peripheral surface. Inside the rod member 310, a penetrating portion 315 is formed in which the tip portion 311 is blocked. The second spring 320 for applying an elastic force to the rod member 310 is accommodated in the through part 315 of the structure, and the head 331 is provided in the support part 205 through the inside of the second spring 320.

That is, the head 331 of the support pin 330 is fixed to the support 205, the rod member 310 is lowered by the second spring 320 located between the tip 311 and the support pin 330 It is elastically biased to protrude from the housing 200.

The holding part is to maintain the holding state in which the rod member 310 is immersed in the lower housing (200). In this holding state, the second spring 320 is compressed. The holding part is fitted between the ball 250 accommodated in the guide groove 202 formed in the support part 205 and the inner peripheral surface of the end of the lower housing 200 and the support part 205 in the state where the ball 250 is accommodated. Cover member 350 is included.

The cover member 350 is for releasing the holding state by being pressed. The inner circumferential surface of the cover member 350 is formed with a ring-shaped inner circumferential groove 353 therefrom, and the ball 250 is selectively accommodated in the inner circumferential groove 3530. The cover member 350 has a lower housing 200. A third spring 370 is interposed between the inner end of the cover member 350 and the end of the support 205 so that it can be restored back to its initial position after being pressed against it.

3 to 8, the operation of such an injection device will be described.

After the upper housing 100 and the lower housing 200 are separated, the syringe 10 having the support jaw 11 formed at one end thereof is inserted into the syringe support member 130. The injection liquid is accommodated in this syringe 10.

When the rod member 310 completely protrudes from the lower housing 200, the holding part maintains the state as shown in FIG. 3. At this time, when the rod member 310 is immersed into the lower housing 200 while applying the force in the longitudinal direction to the rod member 310, the jaw portion 313 to the place where the ball 250 is located as shown in FIG. Moves.

When the force is further applied to the rod member 310, the end of the jaw portion 313 moves the ball 250 to the position of the inner circumferential groove 353 of the cover member so that the ball is received in the inner circumferential groove 353. When the ball is accommodated in the inner circumferential groove 353, the jaw portion 313 is able to pass through the ball 250 and is moved to the head 331 of the support pin 330.

When the jaw portion 313 passes completely through the ball 250, the ball 250 is released from the inner circumferential groove 353 by its own weight and returns to the initial position. In this case, when the force applied to the rod member 310 is removed, the second spring 320 applies an elastic force in the direction in which the rod member 310 protrudes from the lower housing 200. However, as shown in FIG. 5, the ball enters the trajectory of the jaw portion 313 so that the rod member 310 may not be moved by the ball 250, resulting in a holding state.

When the rod member 310 is fully immersed and held in the lower housing 200, the lower housing 200 is coupled to the upper housing 100 to have a state as shown in FIG. 6.

Next, after the seating portion 115 of the injection device is seated on the penis, the cover member 350 is pressed in the P direction as shown in FIG. 7, and the inner circumferential groove 353 of the cover member 350 is the jaw portion 313. ) Up to the position of the ball 250 is fixed. Then, the ball 250 holding the jaw portion 313 moves to the inner circumferential groove 353, whereby the rod member 310 may protrude from the lower housing 200, thereby releasing the holding state. The rod member 310 is elastically biased by the second spring 320 and immediately protrudes from the lower housing 200. That is, the second spring 320 protrudes the rod member 310 instantaneously.

As the rod member 310 protrudes, the tip of the rod member 310 presses the piston 12 as shown in FIG. 8. The pressure applied to the piston 12 exerts a conveying force on the syringe 10 and moves the syringe support member 130 that supports the syringe 10 to the front. When the syringe support member 130 is momentarily moved forward, the needle 10a is momentarily injected into the penis while projecting outward through the seating portion 115.

The syringe support member 130 moving in the upper housing 100 is no longer movable and in this state, the rod member 310 further presses the piston 12.

Then, as shown in Figure 9, the tip portion 311 further advances the piston 12 to inject the injection into the penis through the injection needle (10a). In this case, since the scale 115a is attached to the seating portion 115, the protruding length of the seating portion 115 may be determined with reference to the scale 115a, whereby the needle 10a injected into the penis is used to determine the length. I can adjust it.

12 to 18, the operation of such an injection apparatus will be described.

When the rod member 310 completely protrudes from the lower housing 200, the holding part maintains a state as shown in FIG. 12.

Next, when the rod member 310 is immersed into the lower housing 200 while applying a force in the longitudinal direction of the rod member 310, the jaw portion 313 until the ball 250 is positioned as shown in FIG. Moves.

Applying more force to the rod member 310, the end of the jaw portion 313 moves the ball 250 to the inner circumferential groove 353 position of the cover member so that the ball 250 is received in the inner circumferential groove 353. do. When the ball is accommodated in the inner circumferential groove 353, the jaw portion 313 is able to pass through the ball 250 and is moved to the head 331 of the support pin 330.

When the jaw portion 313 passes completely through the ball 250, the ball 250 is released from the inner circumferential groove 353 by its own weight and returns to the initial position. In this case, when the force applied to the rod member 310 is removed, the second spring 320 applies an elastic force in the direction in which the rod member 310 protrudes from the lower housing 200. However, as shown in FIG. 14, the jaw portion 313 has the ball 250 entering the trajectory of the jaw portion 313 so that the rod member 310 cannot be moved by the ball 250. And eventually a holding state.

When the rod member 310 is fully immersed and held in the lower housing 200, the upper housing 400 is coupled to the lower housing 200 as shown in FIG. 15. At this time, the upper cap 50 is in a state separated from the upper housing 400, the syringe 20 is placed between the upper cap 50 and the upper housing 400 is placed therein.

Next, after the seating portion 115 of the injection device is seated on the penis, the cover member 350 is pressed in the P direction as shown in FIG. 17, and the inner circumferential groove 353 of the cover member 350 is the jaw portion 313. ) Up to the position of the ball 250 is fixed. Then, the ball 250 holding the jaw portion 313 moves to the inner circumferential groove 353, whereby the rod member 310 may protrude from the lower housing 200, thereby releasing the holding state. Then, the rod member 310 is elastically biased by the second spring 320 and immediately protrudes from the lower housing 200. That is, the rod member 310 is instantaneously protruding due to the elastic force of the second spring 320.

As the rod member 310 protrudes, as shown in FIG. 18, the tip of the rod member 310 presses the piston 22. The pressure applied to the piston 22 causes the syringe 20 to be forwarded from the inside of the syringe transfer member 430 to cause the needle 20a to momentarily protrude through the seating portion 115. When the syringe 20 is sufficiently advanced, the tip of the syringe 20 is caught by the inner jaw 50a of the upper cap 50, and stops without moving further. At this time, the injection needle 20a protruding through the seating portion 115 is instantaneously injected into the penis.

Thereafter, in the state in which the forward movement is stopped by the upper cap 50, as shown in FIG. 19, the rod member 310 presses the piston 22 more. In this process, the injection liquid inside the syringe 20 is injected into the penis. At this time, since the scale 115a is attached to the seating portion 115, the protruding length of the seating portion 115 may be determined with reference to the scale 115a, whereby the needle 20a injected into the penis may increase the length. I can adjust it.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

As described above, the injection device according to the present invention, because the injection needle is injected into the penis instantaneously can minimize the pain caused during the injection process.
