Description

  The present invention relates to a prostate massage device, and more particularly to a prostate massage device that stimulates the prostate by a head inserted into the rectum.

  Prostate massagers that stimulate the prostate by being inserted into the rectum are disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-2333028 (Patent Document 1), Japanese Patent Application Laid-Open No. 2002-165857 (Patent Document 2), and Japanese Translation of PCT International Publication No. 2004-509713. (Patent Document 3), US Pat. No. 5,797,950 (Patent Document 4), US Pat. No. 5861000 (Patent Document 5), US Pat. No. 6,589,193 (Patent Document 6), and the like.

  The prostate massagers described in these publications each have a generally ellipsoidal head that is inserted into the rectum from the anus. The lower part of the head is a base having a tapered surface that is tapered, and the base is pushed up toward the prostate by contraction and relaxation of the anal sphincter. As a result, the top or side of the head of the head presses the prostate from the rectum to stimulate the prostate.

  In such a prostate massage device, Patent Document 1, Patent Document 4, Patent Document 5, and Patent Document 6 are provided with a C-shaped or L-shaped leg at the lower part of the ellipsoidal head. A prostate massage device is disclosed. The tip of the leg has a protrusion that hits the perineum, and the protrusion hits the perineum when inserted into the anus, and can simultaneously stimulate the perineum.

  And patent document 1 and patent document 6 are equipped with the buttocks which have the taper surface which spreads in the end following the lower part of the head, and the prostate massage tool provided with the said leg part in the lower part of the said buttocks. . When the anal sphincter contracts, the buttocks receive a force that moves downward. Therefore, by providing a difference between the taper slope at the base of the head and the taper slope at the buttocks, the distance between the head movement in the rectum and the protrusion are met. The pressure applied to the shade can be adjusted.

  Furthermore, Patent Document 5 does not include a buttock at the lower part of the head, but is provided at the lower part of the head in order to be able to adjust the movement distance in the rectum and the pressure applied to the perineum by the protrusion. A prostate massage device is disclosed that includes an axial bar-like support member and an axial bar-like support member having legs extending downwardly in a hook shape and an adjustment mechanism that adjusts the crossing angle of the two support members.

JP 2000-233028 A JP 2002-165857 A JP-T-2004-509713 US Pat. No. 5,797,950 US Pat. No. 5861000 US Pat. No. 6,589,193

  However, the distance between the perineum and the anus and the location of the prostate vary from user to user. If the length of the leg portion of the prostate massage device is not appropriate for the user, a sufficient massage effect cannot be obtained. Therefore, even if the movement distance of the head in the rectum and the pressure applied by the protrusion to the perineum can be adjusted by providing the buttocks at the lower part of the head, it is not always perfect.

  Moreover, in the prostate massage tool having a leg part disclosed in Patent Document 5, the crossing angle between the support part provided in the buttocks and the support part provided in the leg part can be adjusted, thereby obtaining a more appropriate massage effect. be able to. However, since both support parts exist below the leg part, the prostate massage device becomes large. In addition, since an adjustment mechanism for adjusting the crossing angle between the two support members is required, the mechanism of the prostate massage tool becomes complicated and inconvenient.

  The prosthetic massage device with a structure in which the tip of the protrusion at the tip of the leg hits the perineum and the anal sphincter holds the base of the head is supported only at two points, that is, the tip of the protrusion and the base of the head. The prostate massage device is held in an unstable state, and the massage effect may not be sufficient. In addition, since the tip of the protrusion has a structure that stimulates the perineum, there are cases where stimulation to the perineum is insufficient.

  The present invention has been made in view of the problems of the background art described above, and is capable of stimulating the prostate and the perineum without providing a buttocks while stably holding the prostate massage device with a simple structure. The aim is to provide a prostate massage tool that can be given adequately.

  Therefore, in the present invention, the insertion direction of the head inserted into the rectum is changed by allowing the head to be inverted at the attachment position to the leg, and the perineum is forward from the tip of the leg. By providing the stimulating part so that it can be pulled out, the distance between the perineal stimulation part and the prostate stimulation position of the head can be changed.

  In addition, the perineum stimulation part is configured so that the cross section thereof is substantially M-shaped so that both sides of the perineum are supported and stimulated from both sides of the perineum.

  According to the present invention, it is possible to adjust the position of the perineal stimulation unit and adjust the distance between the perineal stimulation unit and the base of the head to a length suitable for the user. Also, since the head is provided to be movable upside down, the position of the head changes as the head enters the rectum, regardless of the position of the user's prostate and the distance between the perineum and the anus. The top of the head and its vicinity stimulate the prostate well. And since the cross-section of the perineum stimulation part is substantially M-shaped, the perineum stimulation part can be positioned so as to sandwich the perineum. As a result, the massage device is held at a total of three points: two on the perineum stimulation part that supports both sides of the perineum and one on the tapered head base tightened by the anal sphincter. Stable retention is expected compared to prostate massage devices.

  The prostate massage device of the present invention has a head inserted into the rectum, a leg portion having a substantially C-shape or a substantially U-shape, and a perineum stimulation portion having a substantially M-shaped cross section. The lower part of the leg part is provided in the leg part so as to be movable upside down by a rotation support part provided at the tip part of one end part of the leg part, and the perineum stimulation part can be pulled forward from the other end tip of the leg part. Is provided. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  1 is a perspective view of a prostate massage device 1 according to an embodiment of the present invention, FIG. 2 is a partial perspective view showing a perineal stimulation unit 30 of the prostate massage device 1, and FIG. FIG. 4 is an exploded perspective view showing a state where 10 is removed, and FIG.

  The prostate massage device 1 of the present invention includes a head 10 that is inserted into the rectum 101, a leg 20 that holds the head 10 upside down, and a meeting that stimulates the perineum 104 provided at the tip of the leg 20. A negative stimulation unit 30 is provided. Each of these parts is made of a material that can give a safe and sufficient stimulus to the human body, such as a plastic material or a hard rubber material.

  The head 10 has a rounded top 11 and a base 13 having a tapered surface 12 that tapers from the top 11 toward the lower end, and is inserted into the rectum 101 so that the top 11 is placed in the rectum 101. To stimulate the prostate 102. The head 10 shown in FIG. 1 is manufactured such that the top 11 thereof is inclined forward, that is, in the direction in which the perineal stimulation unit 30 is located. More specifically, the head 10 includes a curved portion 14 that is convex on the back side thereof, and the center line (indicated by a line A in FIG. 4) of the top 11 when the head 10 is upright. Inclined forward from a vertical line (indicated by line B in FIG. 4) with respect to the bottom surface of the leg 20. In addition, a narrowed portion 15 in which the front side of the head 10 is depressed is formed about ¼ to ３ of the head length from the top of the head 11. The tapered surface 12 is directed downward from the lower end of the narrowed portion 15 on the front side of the head portion 10, and is approximately the head length (height of the head portion 10) from the crown portion 11 on the back side of the head portion 10. It is formed downward from about 2/3 and constitutes the base 13 of the head 10. The base portion 13 is a line that passes through substantially the center of the cross section of the taper surface 12 in a state where the head portion 10 is upright, and is substantially evenly distributed on the front side, the rear side, and the left and right side surfaces of the head portion 10 (see FIG. 4 and is drawn so as to be substantially vertical). A rotation support portion 16 positioned below the base portion 13 of the head portion 10 is an attachment portion to the leg portion 20.

  The head 10 is attached to the upper end of the leg 20 so as to be inverted. As shown in FIG. 3, the rotation support portion 16 of the head 10 has a bifurcated portion 17 in which the center of the base end is cut away from the lower base end of the head 10 upward. The bifurcated portion 17 is attached to the leg portion 20 so as to sandwich a flat attachment portion 23 formed at the upper end portion of the leg portion 20. After the attachment portion 23 of the leg portion 20 is fitted into the bifurcated portion 17 of the rotation support portion 16 of the head 10, a single fixing pin is inserted into the pin insertion hole 23 a of the attachment portion 23 and the pin insertion hole 17 a of the bifurcated portion 17. 18 is inserted. As a result, the head portion 10 is movable upside down with the fixed pin 18 as a rotation center. Further, the cutout of the bifurcated portion 17 limits the movable range, and the cutout of the bifurcated portion 17 is movable within a range in which the head 10 is folded forward from a position where the head 10 is almost upright. Is formed. The angle when folded forward is not particularly limited. Although it is influenced by the shape of the leg 20, particularly the inclination of the crown 11 (the angle between the center line A of the crown 11 and the vertical line B with respect to the bottom of the leg 20), preferably the leg when folded. The movable range is limited so that the center line (indicated by the line D in FIG. 4) of the upper leg portion 21 located at the upper portion of the head 20 substantially coincides with the center line (line B) of the head 10. More specifically, the angle formed by the center line (line B) of the head 10 and the center line (line D) of the upper leg portion 21 is preferably movable within a range of 30 to 90 degrees. However, the movable range is exemplary, and this range depends on the length of the head 10, the inclination of the top 11, etc. so that the top 11 can conveniently stimulate the prostate when the head 10 is folded. As appropriate. As described above, the head 10 of the prostate massage device 1 of the present invention can freely move between a substantially upright state and a folded state as shown in FIG. In order for the parietal portion 11 to stimulate the prostate 102, the head portion 10 should not move at all, and the rotation support portion 16 is notched to such an extent that it moves gradually with a certain amount of force. The width, the thickness of the mounting portion 23 of the leg portion 20, the thickness of the fixing pin 18, and the like are adjusted.

  The leg 20 holds the head 10 and the perineal stimulation unit 30. The leg portion 20 has a substantially C shape or a substantially U shape when viewed from the side. The leg part 20 is formed so as to hold a leg part lower part 22 and a head part 10 formed in a substantially straight line, and draw a C-shaped substantially arc or substantially elliptical arc obliquely upward and forward from the leg part lower part 22. It has a leg upper part 21. The leg portion 20 is formed in a rounded columnar shape having a substantially circular or elliptical cross section. The mounting portion 23 is formed at the tip of the leg upper portion 21 as described above, and the head portion 10 is held. The perineum stimulation part 30 is attached to the tip of the leg lower part 22 so that it can be pulled out from the tip. FIG. 6 shows a state in which the perineal stimulation unit 30 is pulled out, and FIG. 7 shows the pulling mechanism.

  The leg part lower part 22 is formed in a hollow shape from the tip of the leg part lower part 22 toward the connection portion with the leg part upper part 21 by a length that can accommodate at least the shaft-bar-shaped drawer member 33. The cross section of the storage portion 24 that is hollow is formed in a size that substantially matches the cross section of the drawer member 33, and the drawer member 33 can be inserted therethrough. A perineum stimulation unit 30 is provided at one end of the drawer member 33. On the side surface near the other end of the pull-out member 33, several vertical grooves 34 are arranged in the pull-out direction. On the other hand, the side surface of the storage portion 24 is formed with a protrusion 25 that is locked to the vertical groove 34. The longitudinal length of the drawer member 33 can be temporarily maintained by the vertical groove 34 and the protrusion 25. When the position of the vertical groove 34 to be locked to the protrusion 25 is changed, the pull-out length of the pull-out member 33 is changed, and the position of the perineum stimulation part 30, that is, the perineum stimulation part 30 and the rotation support part. The distance between 16 is adjusted.

  As shown in FIG. 2, the perineum stimulation part 30 is formed in a substantially hemispherical shape or a substantially semi-elliptical spherical shape having a rounded upper end. The upper end position is higher than the upper end position of the leg lower part 22. Further, as shown in FIG. 9, the perineum stimulating portion 30 is formed in a substantially M-shaped cross section having a groove portion 31 having a substantially U-shaped cross section at the center of the upper end thereof, and the perineum 104 is formed on both sides of the groove portion 31. It has the press part 32 which applies a pressure. As a result, as shown in FIG. 9, the perineum 104 fits into the groove portion 31, and the perineum stimulation unit 30 stimulates the perineum 104 from both sides. Further, the groove portion 31 has an inclination in which the front is upward with respect to the bottom surface of the leg portion 20. For this reason, the entire groove 31 holds the perineum 104 and can stimulate the perineum in a wide range including the pressing portion 32. Of course, this inclination is not necessary.

  Since the prostate massage tool 1 has the head 10 which is movable upside down, the prostate massage tool 1 moves as shown in FIG. First, after the user adjusts the pulling position of the perineal stimulation unit 30, the user applies the perineal stimulation unit 30 to the perineum 104, and the head 10 is moved from the parietal region 11 to the rectum 101 as shown in FIG. Insert inside. At this time, the anal sphincter is in a relatively relaxed state, and the head 10 is in a substantially folded state. When the head 10 is further inserted into the rectum 101, the head 10 rises and the parietal portion 11 applies pressure to the prostate 102 ((b) in the figure). When the head 10 penetrates deeply into the rectum 101, the base 13 of the head 10 is positioned near the anal sphincter. In this state, if the anal sphincter muscles become tense, the head 10 tries to insert deeper because the taper surface 12 exists. As a result, the prostate 102 is further stimulated. Further, as the head 10 is inserted into the rectum 101, the angle between the head 10 and the leg 20 changes, so that the distance between the position for stimulating the prostate 102 and the perineum stimulation unit 30 changes, and the perineum. In the state where the pressing part 32 of the stimulating unit 30 stimulates the perineum 104, the parietal part 11 stimulates the prostate 102 at a good position ((c) in the figure). Further, in this state, only the base 12 of the head 10 enters the rectum 101, and the rotation support 16 of the head 10 has the mounting portion 23 of the leg 20, so that the head 10 further penetrates deeper. Is prevented. Note that reference numeral 103 in FIG. 10 denotes the bladder.

  Thus, the prostate massage tool 1 of the present invention is provided with the head 10 inserted into the rectum 101 so as to be movable upside down at the tip of the upper leg 21, so that the head 10 enters the rectum 101. Accordingly, the posture of the head 10 inserted into the rectum 101 changes, and the head portion 11 is adjusted to an angle at which the prostate 102 is easily stimulated. In addition, since the perineum stimulation unit 30 is provided so that it can be pulled out at the tip of the lower leg portion 22, the distance between the perineum stimulation unit 30 and the base 13 of the head 10 is adjusted to a position suitable for the user. In this way, the perineum 104 and the prostate 102 are stimulated without causing a positional shift even by the intrusion angle of the head 10. For this reason, unlike the massage tool 1 disclosed in Patent Document 1 and Patent Document 6, the prostate massage tool 1 of the present invention has a buttocks extending downward and extending downward at the bottom of the head 10. In spite of not doing, good stimulation can be applied to the prostate 102 and the perineum 104. And since the perineum stimulation part 30 has a substantially M-shaped cross section, as a result of the two pressing parts 32 formed on the upper part sandwiching the perineum 104, the massage device 1 is held more stably. .

  In particular, it includes a curved portion 14 that is convex on the back side, and a throttle portion 15 in which the front surface of the head 10 is recessed to the back side in the vicinity of about 1/4 to 1/3 of the head length from the top portion 11. By providing the head 10 in which the center line (line A) of the top 11 is inclined forward with respect to the vertical line (line B) with respect to the bottom surface of the leg 20 in a state where the head 10 is upright, the top of the head 10 11 more preferably stimulates the prostate 102.

  In the first embodiment, the prostate massage device 1 having the curved portion 14 that is convex on the back side and the head portion 10 in which the center line (line A) of the crown portion 11 is inclined forward has been described. Is not necessarily the head 10 in which the center line (line A) of the top 11 is inclined forward, and for example, a head 10 as shown in FIG. 11 can be used. The head portion 10 has a top portion 11 having a rounded upper end and a base portion 13 having a tapered surface 12 that tapers from the lower end to the lower end of the top portion 11. In the head 10, a center line (not shown) of the top 11 is parallel to a vertical line (not shown) with respect to the bottom surface of the leg 20.

  In this prostate massage device 1 as well, the angle formed by the head 10 and the leg 10 inserted into the rectum 101 is changed, and the head 10 is adjusted to an angle at which the prostate 102 is easily stimulated. In addition, since the perineum stimulation unit 30 is provided so that it can be pulled out at the tip of the lower leg portion 22, the distance between the perineum stimulation unit 30 and the base 13 of the head 10 is adjusted to a position suitable for the user. Thus, the prostate gland 102 can be stimulated without causing a positional shift depending on the intrusion angle of the head 10. And since the perineum stimulation part 30 has a substantially M-shaped cross section, the perineum 104 will be pinched | interposed and the massage tool 1 will be hold | maintained more stably.

  Each of the above embodiments is merely an example, and it goes without saying that the present invention is not limited to the above embodiment. As described above, the present invention includes the head 10 at the upper end of the leg 20 so as to be movable upside down and the perineal stimulation unit 30 having a substantially M-shaped cross section at the lower end of the leg 20 so as to be able to be pulled out. 103 and perineum 104 are appropriately stimulated, and the shape and size of the head 10, the shape and size of the leg 20, the size and shape of the perineum stimulation unit 30 are appropriately determined. Can be changed.
