Description

Technical Field

[0001] This invention relates to a sperm collector drive device and a sperm collection system, which can improve the collection efficiency of male sperm through a sperm collector. Background Technology

[0002] As a type of sperm collector, a simple sperm collector is known to be available at low cost and, because it is disposable or washable, does not cause hygiene or health problems.

[0003] For example, Patent Document 1 discloses a rotation drive device for a sperm collection section, which includes: a mounting section for inserting a cylindrical sperm collection section that can be inserted into the penis; and a mounting section for the sperm collection section having an air bag inserted into the gap to fill the gap between the mounting section and the sperm collection section, and the device also includes a drive device for rotating the mounting section.

[0004] Patent Document 2 discloses a sperm collector comprising: a core component made of a cylindrical elastic material and having an insertion space that moves relative to the penis inserted into the insertion port; and a container with an opening at its base, a vent at its front end, and an inner space for accommodating the core component, wherein the base end of the core component is supported by the opening of the container. Furthermore, Patent Document 2 discloses a decompression device that holds the front end portion of the sperm collector and freely depressurizes the contents of the container through the degassing vent.

[0005] The rotary drive device in Patent Document 1 causes the sperm collection part inserted into the penis to rotate electrically and slide and rub against the penis along the direction of rotation to stimulate the penis and promote ejaculation.

[0006] The decompression device in Patent Document 2 decompresses the contents of the sperm collector through a degassing hole, thereby increasing the stimulation of the penis during sliding friction as it moves relative to the core component in the insertion space, thus promoting ejaculation.

[0007] However, while the rotary drive device in Patent Document 1 can rotate the sperm collection section, it cannot depressurize the interior of the sperm collection section. Conversely, while the depressurization device in Patent Document 2 can depressurize the contents of the sperm collector, it cannot rotate the sperm collector.

[0010] Patent Document 1: Japanese Patent Application Publication No. 2016-209502

[0011] Patent Document 2: International Publication No. 2016 / 132462 Summary of the Invention

[0012] The problem the invention aims to solve

[0013] If the sperm collector can be rotated while the container is depressurized, the stimulation to the penis can be increased by sliding friction along the direction of rotation, compared to rotating the sperm collector without depressurizing the container, thus enabling more efficient sperm collection. However, to date, no method has been proposed that allows for simultaneous depressurization and rotation of the sperm collector.

[0014] Even if the structure for rotating the sperm collector described in Patent Document 1 is simply combined with the structure for depressurizing the container of the sperm collector described in Patent Document 2, it is not easy to assemble the degassing unit for depressurizing the two parts that are rotating relative to each other without hindering the relative rotation between the two parts.

[0015] This invention was made in view of this situation, and its purpose is to efficiently collect sperm.

[0016] means for solving problems

[0017] To address the aforementioned problems, the present invention provides a sperm collector driving device that detachably holds a sperm collector and rotates the sperm collector while holding it. The sperm collector comprises: a core component made of an elastic material and having a penile insertion space within it; and a container comprising a hollow component having an opening at one axial end and ventilation holes at the other axial portions, and housing the core component within its inner space. The sperm collector driving device is characterized by comprising:

[0018] A retaining part, which detachably holds the sperm collector; and

[0019] The negative pressure introduction rotating part causes the sperm collector held by the holding part to rotate around the axis center, and introduces negative pressure into the container through the vent.

[0020] The effects of the invention

[0021] According to the present invention, sperm can be collected efficiently. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described with reference to the embodiments shown in the accompanying drawings. It should be noted that, in the following description, the sperm collector drive device 100 is referred to as the drive device 100.

[0036] Figure 1 (a) to Figure 1 (d) in the figure is a front view, top view, bottom view, and rear view showing the external structure of the drive device 100 according to an embodiment of the present invention. Figure 2 (a) to Figure 2 (e) is a front view, top view, bottom view, perspective view, and B-B' sectional view showing an example of the structure of the sperm collector 200 held in the drive unit 100. Figure 3This is a cross-sectional view along line A-A' of the drive unit 100 that retains the front part 204a of the sperm collector 200.

[0037] Figure 1 The drive unit 100 shown is held in place by means of easy loading and unloading. Figure 2 The front part 204a of the sperm collector 200 illustrated in the diagram allows the sperm collector 200 to rotate around its central axis CL, and introduces negative pressure into the sperm collector 200 (the container), thereby efficiently collecting sperm. Figure 3 As shown, the sperm collection system 1 is configured such that the front part 204a of the sperm collector 200 is held in the drive device 100.

[0038] <Sperm Collector 200>

[0039] Before describing the drive unit 100, the sperm collector 200 will be described. For example... Figure 2 (a) to Figure 2 As shown in (e), the sperm collector 200 includes: a cylindrical core component 210, which is made of an elastic material such as an elastomer, and has a penile insertion port 212 and an insertion space 214 extending from the insertion port 212 inside; a container 202, which is made of a hollow component made of rigid plastic, and has the core component 210 housed in its inner space; and a cushioning material 220, which is disposed between the core component 210 and the container 202, and is made of an elastic component (such as a sponge) with ventilation.

[0040] Container 202 includes: a container body 204 having an opening 204b at its base end (one axial end) and a vent 204c at its front portion (other axial portions) 204a; and a cover 206, which is installed or removed from the opening 204b of the container body 204. Core component 210 includes: a flange 211 having a penile insertion port 212; and a cylindrical core body 213 having a penile insertion space 214 extending from the insertion port 212 within its interior. The flange 211 is fixedly or detachably supported relative to the opening 204b of the container body 204, and the core body 213 is supported within the inner space of the container 202 by cushioning material 220 disposed around it. If the cover 206 is installed on the container body 204, the flange 211 (insertion port 212) is covered by the cover 206 and cannot be observed from the outside.

[0041] <Overview of Drive Unit 100>

[0042] Next, an overview of the drive unit 100 will be described. Figure 1 (a) to Figure 1 (d) and Figure 3The drive device 100 shown includes: a generally cylindrical housing 110 that can be held by a human hand and has an opening 110a' at a base end 110a; a holding part 120 that is rotatably (and non-detachably) assembled into the base end opening 110a' of the housing 110 and holds the front part 204a of the sperm collector 200 in a detachable manner; and a drive mechanism (negative pressure introduction rotation part) DM that is housed in the housing 110 and rotates the sperm collector 200 held by the holding part 120 about an axis center, and introduces negative pressure into the container 202 through the vent 204c of the sperm collector 200.

[0043] The housing 110 is made of relatively rigid plastic and has a narrowed portion 111a at its axial midpoint. On the front of the housing 110, four circular switches 114 (114a to 114d) that are operated during use of the drive unit 100 are axially spaced on the narrowed portion 111a. It should be noted that the individual circular switches 114 will be described later. A power plug 149 for supplying power is detachably fitted onto the back of the narrowed portion 111a (see...). Figure 7 ) power supply terminal (female terminal) 116.

[0044] The retaining part 120 includes: a cup-shaped rotating bracket 121 made of rigid plastic and having a concave inner surface that matches the front part 204a of the sperm collector 200; a bracket side rubber ring 122 installed at the center of the inner surface of the rotating bracket 121 and made of an annular elastic component (e.g., rubber, elastic resin); and a generally cylindrical locking ring 123 made of rigid plastic and installed on the inner circumferential surface of the rotating bracket 121 near the base end, with a protrusion 123a formed on its inner circumferential surface for locking the front part 204a of the sperm collector 200.

[0045] like Figure 3 As shown, if the front part 204a of the sperm collector 200 is housed in the concave inner surface of the rotating bracket 121, the locking ring 123 locks the front part 204a of the sperm collector 200. Thus, within the rotating bracket 121, the front part 204a of the sperm collector 200 is held in a state where it can be easily installed and removed and can rotate around the axis center together with the rotating bracket 121.

[0046] A support-side rubber ring 122 is installed on the inner surface of the front end side of the rotating support 121. When the front part 204a of the sperm collector 200 is maintained, the support-side rubber ring 122 is configured to communicate with the vent 204c of the sperm collector 200 through the inner circumferential space 122a of the support-side rubber ring 122 and to be airtight with the outside.

[0047] like Figure 3As shown, the internal space of the housing 110 houses the drive mechanism (negative pressure introduction rotating part) DM, which causes the sperm collector 200 held by the rotating bracket 121 to rotate around the axis center and introduces negative pressure into the container 202 through the vent 204c.

[0048] The drive mechanism DM includes: a motor 131 fixed in the central part of the housing 110; a pump 132 fixed in a position closer to the front end than the motor 131 and generating negative pressure; a shaft 151, which is a tube fixed to the rotating shaft 131b of the motor 131 and the rotating support 121 respectively and rotates about the shaft center, and communicates between the base end opening 151a (one end opening) and the outer peripheral surface opening 151b through the internal flow path 151c of the shaft; and a bearing part 137 that rotatably supports the shaft 151 and forms a pressure regulating space RS around the outer peripheral surface opening 151b.

[0049] Pump 132 is connected to bearing 137 via pump pipe 147, and the negative pressure generated by pump 132 is introduced into pressure regulating space RS.

[0050] The base opening 151a of the shaft 151 is connected to the inner circumferential space 122a of the support-side rubber ring 122. Therefore, the inner circumferential space 122a of the support-side rubber ring 122 is connected to the pressure regulating space RS of the bearing portion 137 through the internal flow path 151c of the shaft.

[0051] Therefore, when the rotating support 121 holds the front part 204a of the sperm collector 200, the negative pressure generated by the pump 132 is introduced into the container 202 of the sperm collector 200 through the pressure regulating space RS of the bearing part 137, the internal flow path 151c, the inner peripheral space 122a of the support side rubber ring 122, and the vent 204c of the sperm collector 200. As a result, compared with not introducing negative pressure into the container 202, the degree of contact between the penis and the core component 210 (the inner surface of the core body 213) is increased, and the stimulation to the penis when the core component 210 slides and rubs against the penis in the rotation direction is increased, enabling efficient sperm collection.

[0052] Furthermore, the drive mechanism DM includes a solenoid valve 133, which is fixed to the left side of the motor 131 and connected to the pressure regulating space RS of the bearing section 137 via a valve tube 148. The solenoid valve 133 connects or blocks the flow path within the valve tube 148 and the internal space of the housing 110. Since the internal space of the housing 110 reaches atmospheric pressure, if the solenoid valve 133 is opened during the operation of the pump 132, the negative pressure generated by the pump 132 and the atmospheric pressure are respectively introduced into the pressure regulating space RS of the bearing section 137. As a result, compared with the pump 132 operating when the solenoid valve 133 is closed, the negative pressure introduced into the container 202 of the sperm collector 200 is weaker, the tightness between the penis and the core component 210 is reduced, and the stimulation to the penis is weakened.

[0053] Figure 4 (a) is an enlarged cross-sectional view of the main parts when the motor 131 is rotated without operating the pump 132. Figure 4 (b) is an enlarged sectional view of the main parts that cause the pump 132 to operate and the motor 131 to rotate. Figure 4 (c) is an enlarged cross-sectional view of the main parts that cause the pump 132 and solenoid valve 133 to operate and the motor 131 to rotate.

[0054] like Figure 4 As shown in (a), when the motor 131 is rotated without actuating the pump 132, no negative pressure is introduced into the container 202 of the sperm collector 200, and the rotating support 121 and the sperm collector 200 held on the rotating support 121 rotate about the axis center. Therefore, the container 202 of the sperm collector 200 becomes at normal pressure (atmospheric pressure), which stimulates the penis inserted into the insertion space 214 of the core component 210 in a rotational direction.

[0055] like Figure 4 As shown in (b), when the pump 132 is operated and the motor 131 is rotated, an airflow is generated as indicated by the arrow labeled "FL1". This creates a negative pressure within the container 202 of the sperm collector 200, causing the rotating support 121 and the sperm collector 200 held on the rotating support 121 to rotate around their central axis. Therefore, compared to rotating the motor 131 without operating the pump 132, the contact between the penis and the core component 210 is increased, enhancing the stimulation delivered to the penis.

[0056] like Figure 4As shown in (c), when the pump 132 and solenoid valve 133 are operated while the motor 131 is rotated, atmospheric pressure is introduced into the pressure regulating space RS of the bearing 137 through the opening of the solenoid valve 133, as indicated by the arrow labeled "FL2". Therefore, compared with the operation of the pump 132 with the solenoid valve 133 closed, the closeness between the penis and the core component 210 is weakened, which can reduce the stimulation given to the penis.

[0057] Thus, by using the drive device 100 of this embodiment, the sperm collector 200 can be rotated while the pressure inside the container 202 is reduced. Therefore, compared with rotating the sperm collector 200 without reducing the pressure inside the container 202, the stimulation applied to the penis can be increased when sliding friction is applied to the penis in the rotation direction, thereby enabling efficient sperm collection.

[0058] <Details of Drive Unit 100>

[0059] The drive unit 100 will now be described in detail. Figure 5 This is a perspective view of the drive unit 100. Figure 6 It is an exploded perspective view of the various parts that make up the drive unit 100.

[0060] <Shell 110>

[0061] like Figure 5 and Figure 6 As shown, the housing 110 includes: a generally cylindrical intermediate outer shell portion 111, which is open at both axial ends and narrows into a curved concave shape in the middle axial portion (narrowing portion 111a); a cylindrical base end outer shell portion 113, which is installed in a state matching the base end opening of the intermediate outer shell portion 111 and extends through the vertical direction; and a flat plate-shaped front end outer shell portion 112 (cap), which is installed in a state matching the front end opening of the intermediate outer shell portion 111 and is open only at the base end side, wherein each outer shell portion 111, 112, 113 is made of relatively rigid plastic.

[0062] The base opening and front opening of the intermediate housing portion 111 are assembled such that the edges of the base housing portion 113 and the front housing portion 112 are matched. The base housing portion 113 is fixed relative to the intermediate housing portion 111 by, for example, engaging a locking protrusion 113a provided along the edge of the front opening of the base housing portion 113 with a locking recess (not shown) provided on the base opening side of the intermediate housing portion 111. It should be noted that the fixing structure of the front housing portion 112 relative to the intermediate housing portion 111 is also performed in the same manner.

[0063] The narrowing portion 111a provided on the housing 110 (intermediate outer shell portion 111) is the portion that is touched by the pad of the thumb when a person holds the housing 110 with their hand.

[0064] like Figure 5 As shown, four circular switches 114 (114a to 114d) that are operated during use of the drive device 100 are arranged axially at intervals on the narrowing portion 111a. Two circular switches 114a and 114b are arranged closer to the front end side than the bottom 111b of the narrowing portion 111a, and two circular switches 114c and 114d are arranged closer to the base end side than the bottom 111b of the narrowing portion 111a.

[0065] In this embodiment, two circular switches 114a and 114b, positioned closer to the front end than the bottom 111b of the narrowing portion 111a, are used when introducing negative pressure into the sperm collector 200. Two circular switches 114c and 114d, positioned at the base end, are used when rotating the sperm collector 200. Specifically, the circular switch 114a, positioned at the foremost point in the axial direction, is a vacuum switch, operated when switching the power supply to the pump 132 on and off, or switching the vacuum mode (described later). The circular switch 114b, positioned closer to the base end than the vacuum switch 114a, is a release switch (valve switch), operated when opening the solenoid valve 133 during pump 132 operation to reduce stimulation of the penis.

[0066] The circular switch 114c, which holds the bottom 111b of the narrowing section 111a and is positioned closer to the base end than the release switch 114b, is a manual switch and is operated when energizing the motor 131 or maintaining the rotational speed of the sperm collector 200. The circular switch 114d, which is positioned closer to the base end than the manual switch 114c, is an automatic switch and is operated when energizing the motor 131 or switching to automatic mode (described later).

[0067] In the housing 110, a light-emitting display 115 (first light-emitting display 115a) is provided at a position closer to the front end than the vacuum switch 114a, and a light-emitting display 11 (second light-emitting display 115b) is provided at a position closer to the base end than the automatic switch 114d, indicating that the motor 131 is on.

[0068] These light-emitting display units 115a, 115b are, for example, groups of LED 115c and light guide component 115d (see...). Figure 7 It is made of materials that emit light in colors such as green, but can also be other colors.

[0069] <Internal structure of shell 110>

[0070] Next, the internal structure of the housing 110 will be described. Figure 7 This is a longitudinal sectional view of the drive unit 100.

[0071] like Figure 7 As shown, the internal space of the housing 110 houses the drive mechanism DM, and the retaining part 120 is assembled in the base opening 110a' of the housing 110 in a rotatable (and non-detachable) manner.

[0072] As described above, the holding part 120 includes: a cup-shaped rotating support 121 having a concave inner surface that matches the front part 204a of the sperm collector 200; a support side rubber ring 122, which is installed at the center of the inner surface of the rotating support 121; and a generally cylindrical locking ring 123, which is installed on the inner circumferential surface of the rotating support 121 near the base end. As described above, the drive mechanism DM is a unit that rotates the sperm collector 200 held by the rotating support 121 about its axial center and introduces negative pressure into the container 202 through the vent 204c.

[0073] <Drive Mechanism DM>

[0074] like Figure 6 and Figure 7 As shown, the drive mechanism DM, as the main structural unit, includes: a motor 131, which is fixedly disposed in the center of the internal space of the housing 110 such that the rotating shaft 131b faces the base end; a pump 132, which is fixedly disposed in a position closer to the front end than the motor 131 and generates negative pressure; a solenoid valve 133, which is fixedly disposed between the motor 131 and the circular switch 114; a shaft 151, which is a tube that connects the rotating shaft 131b of the motor 131 to the holding part 120 (rotating bracket 121) and transmits the rotation of the motor 131 to the holding part 120, and communicates the base end opening 151a provided at the base end and the outer peripheral surface opening 151b provided on the outer peripheral surface through the internal flow path 151c; and a bearing part 137 that rotatably supports the shaft 151 and forms a pressure regulating space RS around the outer peripheral surface opening 151b for introducing the negative pressure generated by the pump 132.

[0075] In addition, the drive mechanism DM includes: a battery 134, which is located near the motor 131 and provides power; a main board 135, which is mounted on the controller 135a (control unit) and the gyroscope sensor 135b (see...). Figure 9Based on the operation of each circular switch 114 and the rotation operation of the drive mechanism DM, the operation of the motor 131, pump 132 and solenoid valve 133 is controlled; and the switch board 136 is provided corresponding to each circular switch 114 (114a to 114d) and is equipped with switching elements 136a to 136d that perform on and off operations based on the operation of each circular switch 114 and light-emitting elements such as LED 115c.

[0076] Motor 131, solenoid valve 133, battery 134 and main board 135 are mounted on inner housing body 141. Inner housing cover 142 is mounted on the front end of inner housing body 141, and pump 132 is mounted on inner housing cover 142 via pump bracket 143.

[0077] Motor 131 includes a motor body 131a and a rotating shaft 131b protruding from the base end of the motor body 131a. The base end of the motor body 131a is fixed to an internal base component 144 via a motor bracket 145. The rotating shaft 131b is fitted into a mounting hole 151d provided at the front end of shaft 151 and is fixed by a motor collar 152, rotating integrally with shaft 151.

[0078] The base end portion of shaft 151 is fixed to the front end of rotating bracket 121 via connector 146. The base end of shaft 151 extends through the front end of rotating bracket 121, with the base end opening 151a facing the inner circumferential space 122a of bracket-side rubber ring 122. An O-ring 151e is installed at the base end of shaft 151 to seal rotating bracket 121 and shaft 151 in an airtight state. An outer circumferential opening 151b is formed on the outer circumferential surface at the axial midpoint of shaft 151, and the base end opening 151a and the outer circumferential opening 151b are connected through the shaft internal flow path 151c.

[0079] A bearing portion 137 is provided around the shaft 151, which rotatably supports the shaft 151 and forms a pressure regulating space RS around the opening 151b on its outer peripheral surface. Therefore, the pressure regulating space RS of the bearing portion 137 is connected to the inner peripheral space 122a of the support-side rubber ring 122 via the internal flow path 151c. It should be noted that the bearing portion 137 will be described in detail later.

[0080] The pressure regulating space RS is connected to the pump 132 via a pump pipe 147. Therefore, the negative pressure generated by the pump 132 is introduced into the pressure regulating space RS through the pump pipe 147. Similarly, the pressure regulating space RS is connected to the solenoid valve 133 via a valve pipe 148. As described above, the solenoid valve 133 is disposed within the internal space (atmospheric pressure) of the housing 110 and connects or blocks the flow path of the valve pipe 148 and the internal space of the housing 110. Therefore, when the solenoid valve 133 is open, atmospheric pressure is introduced into the pressure regulating space RS through the valve pipe 148.

[0081] <Bearing Section 137>

[0082] Figure 8 This is a partially enlarged cross-sectional view of the area surrounding the bearing portion 137 of the drive unit 100.

[0083] like Figure 6 and Figure 8 As shown, the bearing section 137 includes: a spacer 153 through which the shaft 151 is inserted; a bearing collar 154 disposed within the spacer 153; a pair of X-rings 155 (155a and 155b) that allow the shaft 151 to rotate between the shaft 151 and the spacer 153 while providing an airtight seal between the shaft 151 and the spacer 153; a pair of bearings 156 in which the shaft 151 is inserted into its inner space and are respectively disposed between the X-ring 155a on the base end side and the connecting member 146, and between the X-ring 155b on the front end side and the motor collar 152; a base end side bearing bracket 157 that holds the spacer 153 and the base end side bearings 156 from the base end side; and a front end side bearing bracket 158 ​​that holds the spacer 153 and the front end side bearings 156 from the front end side.

[0084] The spacer 153 includes: a cylindrical spacer body 153a with its axial ends open for insertion of a shaft 151; and a pair of connecting conduits 153b and 153c disposed on the outer peripheral surface of the spacer body 153a to communicate the internal flow path with the inner space of the spacer body 153a. For example, the spacer 153 is made of rigid plastic.

[0085] The spacer body 153a is cylindrical with an inner diameter larger than the outer diameter of the shaft 151, but it can also be cylindrical. The connecting conduits 153b and 153c are cylindrical with a diameter smaller than the axial height of the spacer body 153a, and include: a pump connecting conduit 153b connected to the end of the pump pipe 147; and a valve connecting conduit 153c connected to the end of the valve pipe 148. In this embodiment, the valve connecting conduit 153c is positioned at a position rotated 180 degrees from the pump connecting conduit 153b along the axial center, but is not limited to this angle.

[0086] The bearing collar 154 is a component disposed in the inner space of the spacer body 153a, such that a pair of X-rings 155a and 155b are located at the axial ends of the spacer body 153a, and has, for example, a pair of ring portions 154a and feet 154b that space these pairs of ring portions 154a apart from each other.

[0087] X-rings 155 (155a and 155b) are X-shaped rings made of an airtight elastic material such as rubber. Each X-ring 155 includes: a base-side X-ring 155a (one-end rubber ring) mounted on the base opening 151a of the spacer body 153a; and a front-side X-ring 155b (the other-end rubber ring) mounted on the front opening of the spacer body 153a.

[0088] In this embodiment, since a bearing collar 154 is arranged in the internal space of the spacer body 153a, the base-side X-ring 155a and the front-side X-ring 155b can be arranged axially at intervals. This suppresses the disadvantage of each X-ring 155a and 155b blocking the internal flow paths of each connecting conduit 153b and 153c.

[0089] The bearing 156 is a component that provides rotatable support for the shaft 151, and is held in the base end bearing bracket 157 and the front end bearing bracket 158 ​​respectively.

[0090] The pressure regulating space RS is formed by the spacer body 153a, the base-side X-ring 155a, and the front-side X-ring 155b. Since the outer peripheral surface opening 151b of the shaft 151 is located within the pressure regulating space RS even when the shaft 151 rotates, the pressure regulating space RS and the inner peripheral space 122a of the support-side rubber ring 122 are connected during the rotation of the shaft 151 through the outer peripheral surface opening 151b, the internal flow path 151c, and the base-side opening 151a.

[0091] As described above, the pump connecting conduit 153b is connected to the pump pipe 147, and the negative pressure generated by the pump 132 is introduced into the pressure regulating space RS. Similarly, the valve connecting conduit 153c is connected to the valve pipe 148, and atmospheric pressure is introduced into the pressure regulating space RS when the solenoid valve 133 is open.

[0092] If the retaining part 120 (rotating bracket 121) holds the front part 204a of the sperm collector 200, the base opening 151a of the shaft 151 and the vent 204c of the sperm collector 200 are connected to the outside in an airtight state. Therefore, by actuating the pump 132, the negative pressure generated by the pump 132 can be introduced into the container 202 of the sperm collector 200. As a result, the stimulation to the penis can be enhanced compared to when the negative pressure is not introduced into the container 202 of the sperm collector 200. Similarly, if the solenoid valve 133 is opened during the operation of the pump 132, the tightness between the penis and the core component 210 is weakened compared to when the pump 132 is operated with the solenoid valve 133 closed.

[0093] Thus, the drive device 100 of this embodiment can adjust the stimulation applied to the penis via the motor 131, pump 132, and solenoid valve 133.

[0094] <Structure of the Control System>

[0095] Figure 9 This is a block diagram showing the structure of the control system of the drive device 100. Figure 10 (a) to Figure 10 Figure (e) illustrates the operation and control of vacuum switch 114a, the operation and control of release switch 114b, the operation and control of manual switch 114c, the operation of drive device 100 and control of sperm collector 200 based on detection signal from gyroscope sensor 135b, and the operation and control of automatic switch 114d. Figure 11 This is a three-dimensional diagram illustrating how to use the sperm collection system 1.

[0096] like Figure 9 As shown, the main base plate 135 is provided with: a controller 135a, which serves as the control center of the drive device 100; and a gyroscope sensor 135b (angular velocity sensor), which outputs a detection signal corresponding to the angular velocity of the housing 110 when it rotates.

[0097] In addition, the main substrate 135 is electrically connected to the vacuum switch 114a (switching element 136a), the release switch 114b (switching element 136b), the manual switch 114c (switching element 136c), the automatic switch 114d (switching element 136d), the pump 132, the solenoid valve 133, and the motor 131. Furthermore, although not shown, the main substrate 135 is also electrically connected to the LED 115c.

[0098] The controller 135a controls the operation of the pump 132, solenoid valve 133, and motor 131 based on the operation of each switch 114a to 114d and the detection signal from the gyroscope sensor 135b. The controller 135a is composed of, for example, a programmable controller, hardware logic, or any combination of a CPU and memory. The gyroscope sensor 135b detects the angular velocity of the housing 110 and outputs a detection signal to the controller 135a.

[0099] The following explains the relationship between the operation of each switch 114a to 114d and the control content of the controller 135a.

[0100] <Vacuum Switch 114a>

[0101] Vacuum switch 114a is operated when power is switched on and off for pump 132, or when the operating mode of pump 132 is switched (hereinafter referred to as vacuum mode).

[0102] like Figure 10 As shown in (a), if the vacuum switch 114a is pressed and held for more than 2 seconds, the power supply to the pump 132 can be switched on and off. For example, if the vacuum switch 114a is pressed and held while the power is off, the controller 135a will switch to the power-on state, allowing power to be supplied to the pump 132 from the battery 134. Similarly, if the vacuum switch 114a is pressed and held while the power is on, the controller 135a will switch to the power-off state, stopping the power supply from the battery 134 to the pump 132.

[0103] Furthermore, when the power is on, if the vacuum switch 114a is pressed for less than 2 seconds, the controller 135a will switch the mode to vacuum mode.

[0104] For example, after the power is turned on, the controller 135a is immediately set to vacuum mode "Lo". In vacuum mode "Lo", the pump 132 generates a weak negative pressure, which is introduced into the container 202 of the sperm collector 200.

[0105] If the vacuum switch 114a is pressed briefly once from the vacuum mode "Lo", the controller 135a will switch the mode to the vacuum mode "Hi". In the vacuum mode "Hi", the pump 132 generates a strong negative pressure, which is introduced into the container 202 of the sperm collector 200.

[0106] If the vacuum switch 114a is pressed briefly once from the vacuum mode "Hi", the controller 135a switches the mode to vacuum mode "P1". In vacuum mode "P1", the pump 132 operates in a predetermined mode. For example, the pump 132 repeats the operating state and the stop state in a predetermined first cycle. As a result, the pump 132 repeatedly generates negative pressure in the first cycle, which is introduced into the container 202 of the sperm collector 200.

[0107] If the vacuum switch 114a is pressed briefly once from the vacuum mode "P1", the controller 135a will switch the mode to vacuum mode "P2". Similarly, each time the vacuum switch 114a is pressed briefly, the controller 135a will switch the mode to vacuum mode "P3" and vacuum mode "P4".

[0108] In vacuum modes "P2" to "P4", pump 132 operates in a predetermined mode. For example, in vacuum mode "P2", pump 132 repeats the operating state and the stop state in a second cycle shorter than the first cycle; in vacuum mode "P3", it repeats the operating state and the stop state in a third cycle shorter than the second cycle; and in vacuum mode "P4", it repeats the operating state and the stop state in a fourth cycle shorter than the third cycle.

[0109] Thus, pump 132 repeatedly generates negative pressure from the second to the fourth cycle, which is introduced into container 202 of sperm collector 200.

[0110] <Release Switch 114b>

[0111] Release switch 114b is operated when solenoid valve 133 is opened during the operation of pump 132.

[0112] like Figure 10 As shown in (b), in the non-operating state (open state) where no operation is performed on the release switch 114b, the solenoid valve 133 is closed. As described above, in the closed state of the solenoid valve 133, atmospheric pressure is not introduced into the pressure regulating space RS of the bearing section 137, so the negative pressure generated by the pump 132 is introduced into the container 202 of the sperm collector 200 through the pressure regulating space RS.

[0113] When the operation of the release switch 114b is performed (on state), the solenoid valve 133 is opened. As described above, when the solenoid valve 133 is open, atmospheric pressure is introduced into the pressure regulating space RS of the bearing section 137, so the negative pressure introduced into the container 202 of the sperm collector 200 is weaker compared to when the solenoid valve 133 is closed and the pump 132 is activated.

[0114] In this way, by operating the release switch 114b during the operation of the pump 132, the negative pressure introduced into the container 202 is weakened, thereby adjusting the stimulation applied to the penis.

[0115] In the drive device 100 of this embodiment, since the release switch 114b is operated when adjusting the stimulation applied to the penis, it is envisioned that the operation frequency is more frequent compared to the vacuum switch 114a.

[0116] For example, the power-on and power-off operations of the pump 132 are performed at the start and end of the use of the drive device 100. If the vacuum mode switching operation determines the vacuum mode to be used, no mode change is performed. On the other hand, since the operation of the release switch 114b is performed when it is desired to adjust the intensity of the stimulation applied to the penis, it is envisioned that it will be performed multiple times during the use of the drive device 100.

[0117] Therefore, the release switch 114b is operated more frequently than the vacuum switch 114a.

[0118] Figure 11 As shown, in this embodiment, the release switch 114b is located closer to the bottom 111b of the narrowing portion 111a than the vacuum switch 114a.

[0119] Since it is assumed that when a person holds the drive device 100, the pad of their thumb is located at the bottom 111b of the narrowing portion 111a, by setting the release switch 114b, which is used more frequently than the vacuum switch 114a, closer to the bottom 111b of the narrowing portion 111a than the vacuum switch 114a, the amount of thumb movement during the operation of the release switch 114b can be shortened, and accidental operation of the vacuum switch 114a can be suppressed.

[0120] <Manual Switch 114c>

[0121] The manual switch 114c is operated when power is switched on and off for the motor 131, or when the rotation mode of the motor 131 (sperm collector 200) is changed.

[0122] like Figure 10 As shown in (c), if the manual switch 114c is pressed and held for more than 2 seconds, the power supply to the motor 131 can be switched on and off. For example, if the manual switch 114c is pressed and held while the power is off, the controller 135a will switch to the power-on state, supplying power from the battery 134 to the motor 131. Similarly, if the manual switch 114c is pressed and held while the power is on, the controller 135a will switch to the power-off state, stopping the power supply from the battery 134 to the motor 131.

[0123] Furthermore, when the power is on, if the manual switch 114c is pressed for less than 2 seconds, the controller 135a will switch the mode to rotation mode.

[0124] The rotation modes include: a maintenance mode, which maintains a certain rotation speed and changes the rotation direction of the sperm collector 200 (motor 131) in accordance with the rotation direction of the drive device 100 (housing 110); and a variable mode, which changes the rotation direction and speed of the sperm collector 200 in accordance with the rotation direction and rotation angle of the drive device 100.

[0125] The controller 135a detects the rotation direction and angle of the drive device 100 based on the detection signal from the gyroscope sensor 135b. For example, at the moment when the manual switch 114c is pressed and held to transition to the power-on state, the controller 135a obtains the rotation angle of the drive device 100 based on the detection signal from the gyroscope sensor 135b as the initial origin, and the drive device 100 starts moving in one direction (e.g., from the initial origin). Figure 11 (The right direction indicated by the central label "R") or another direction (e.g.) Figure 11 When rotating to the left (as indicated by the number "L"), the controller 135a obtains the rotation direction from the initial origin as the tilt direction, and obtains the angle difference between the rotation and the initial origin as the tilt angle (rotation angle).

[0126] In this embodiment, if the power is turned on by pressing and holding the manual switch 114c, the controller 135a sets the mode to a variable mode.

[0127] like Figure 10 As shown in (d) of the diagram, in variable mode, when the tilt direction of the drive unit 100 is to the right, the controller 135a controls the motor 131 and rotates the sperm collector 200 to the right; when the tilt direction of the drive unit 100 is to the left, the controller 131 controls the motor 131 and rotates the sperm collector 200 to the left. Furthermore, when the tilt angle is within a reference range (e.g., within ±5 degrees from the initial origin), the controller 135a stops the rotation of the sperm collector 200; when the tilt angle exceeds the reference range, the larger the tilt angle, the higher the rotational speed of the sperm collector 200.

[0128] If the manual switch 114c is pressed briefly in variable mode, the controller 135a will switch to maintenance mode and maintain the rotational speed at the time of the brief press. In maintenance mode, the controller 135a acquires the detection signal from the gyroscope sensor 135b and determines the rotation direction of the sperm collector 200 based on the tilt angle of the drive device 100.

[0129] For example, such as Figure 11As shown, when the tilt direction of the drive device 100 is to the right (R), the controller 135a causes the sperm collector 200 to rotate to the right (RC). When the tilt direction of the drive device 100 is to the left (L), the controller 135a causes the sperm collector 200 to rotate to the left (LC).

[0130] It should be noted that if the manual switch 114c is pressed briefly in the maintenance mode, the controller 135a will switch the mode to the variable mode.

[0131] <Automatic Switch 114d>

[0132] The automatic switch 114d is operated when power is switched on and off for the motor 131, or when the operating mode of the motor 131 is switched (hereinafter referred to as automatic mode).

[0133] like Figure 10 As shown in (e), if the automatic switch 114d is pressed for more than 2 seconds, the power supply to the motor 131 can be switched on and off in the same way as when the manual switch 114c is pressed.

[0134] In this embodiment, if the power is turned on by pressing and holding the automatic switch 114d, the controller 135a sets the mode to automatic mode. In automatic mode, the controller 135a does not use the detection signal from the gyroscope sensor 135b, but rotates the sperm collector 200 according to a predetermined action (a combination of rotation direction, rotation speed, and rotation time).

[0135] In automatic mode, the controller 135a switches to automatic mode with each short press of the automatic switch 114d. In this embodiment, four automatic modes are set, namely "P1" to "P4". The combination of rotation direction, speed and rotation time of the sperm collector 200 in each automatic mode "P1" to "P4" is different, which can provide different stimulation to the penis inserted into the sperm collector 200.

[0136] In this embodiment, when the power is on, the controller 135a sets the mode to automatic mode "P1". Each time the automatic switch 114d is pressed briefly, the controller 135a switches the mode sequentially to automatic mode "P2", automatic mode "P3", and automatic mode "P4". Furthermore, if the automatic switch 114d is pressed briefly in automatic mode "P4", it switches to automatic mode "P1".

[0137] In automatic mode, since the drive unit 100 rotates the sperm collector 200 according to the predetermined actions, the user can apply various kinds of stimulation to the penis without any special operation.

[0138] <Variation Example>

[0139] The drive mechanism DM (referred to as the negative pressure introduction rotating part) illustrated in the above embodiment includes a motor 131, a pump 132, a shaft 151, and a bearing part 137. However, other structures may be adopted as long as the sperm collector 200 held by the holding part 120 can rotate around the axis center and negative pressure is introduced into the container 202 through the vent 204c provided in the container 202 of the sperm collector 200.

[0140] The retaining part 120 is a structure that can be detachably attached to and detachably attached to the front part 204a of the sperm collector 200 (container body 204), but it can also be a structure that can be detachably attached to and detachably attached to parts other than the front part 204a of the container body 204.

[0141] The bearing section 137 includes: a spacer 153 through which the shaft 151 is inserted; a bearing collar 154 disposed within the spacer 153; and a pair of X-rings 155 (155a and 155b) that allow the shaft 151 to rotate between the shaft 151 and the spacer 153 while providing an airtight seal between the shaft 151 and the spacer 153. Although a pressure regulating space RS is formed by the spacer body 153a and the pair of X-rings 155, other structures may be used as long as a pressure regulating space RS can be formed.

[0142] In the above embodiment, an atmospheric pressure is introduced into the pressure regulating space RS via a solenoid valve 133. However, other structures can be used as long as the negative pressure introduced into the container 202 can be weakened. For example, the pump 132 can be controlled to reduce the negative pressure it generates.
