Description

Technical Field

[0001] The utility model specifically relates to an auxiliary sperm collection device. Background Art

[0002] In clinical medicine, semen analysis is the most basic and main test method for judging and evaluating male fertility. To conduct semen analysis, the first step is to obtain male semen. At present, the main way to obtain semen is to use an auxiliary semen collection device to simulate the stimulation of the vagina on the male penis, so that it quickly reaches the threshold.

[0003] However, most of the existing auxiliary sperm collection devices have a simple structure, and are mostly composed of a cylinder and a silicone sleeve simulating a vagina. When the silicone sleeve moves back and forth to rub the penis, the tightness of the silicone sleeve and the penis is not easy to adjust, which reduces the stimulation effect of the silicone sleeve on the penis when rubbing the penis, thereby reducing the sperm collection efficiency of the device. Therefore, in view of the above technical problems, an auxiliary sperm collection device is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes an auxiliary semen collection device, which is convenient for adjusting the tightness of the friction between the silicone sleeve and the penis according to needs, thereby improving the stimulation effect on the penis and thus improving the semen collection efficiency of the device.

[0005] An auxiliary sperm collection device, comprising:

[0006] The sperm collecting cylinder has a sperm collecting cavity extending through it along the axial direction;

[0007] A silicone sleeve is arranged in the semen collection cavity, and the penis can pass through the silicone sleeve. When the silicone sleeve moves back and forth along the penis, the inner wall of the silicone sleeve can rub the penis; and

[0008] The pressing mechanism comprises a rotating shaft, a pressing block and a driving assembly. The wall of the semen collection chamber is evenly provided with a plurality of mounting grooves along its circumference. The rotating shafts are rotatably arranged in the plurality of mounting grooves. The pressing blocks are arranged on the rotating shafts. Rotating the rotating shafts can drive the pressing blocks to protrude from the mounting grooves and squeeze the outer wall of the silicone sleeve. The driving assembly is arranged on the semen collection cylinder and connected with the plurality of rotating shafts. Adjusting the driving assembly can drive the plurality of rotating shafts to rotate synchronously.

[0009] The beneficial effects of the above-mentioned auxiliary sperm extraction device are:

[0010] When in use, the penis is inserted into the silicone sleeve, and then the semen collection tube is moved back and forth repeatedly. The repeated forward and backward movement of the semen collection tube drives the silicone sleeve to move back and forth repeatedly, and the silicone sleeve can rub the penis by repeatedly moving back and forth. During the rubbing process, the multiple sets of rotating shafts are driven to rotate synchronously by adjusting the driving components. The synchronous rotation of the multiple sets of rotating shafts can drive the multiple sets of pressing blocks to rotate so that the multiple sets of pressing blocks squeeze the outer wall of the silicone sleeve. After being squeezed, the outer wall of the silicone sleeve can be deformed inward, thereby tightening the friction between the silicone sleeve and the penis. Conversely, the multiple sets of pressing blocks can be driven to rotate synchronously in the opposite direction by adjusting the driving components. The silicone sleeve is restored at this time, thereby loosening the friction between the silicone sleeve and the penis. It is convenient to adjust the tightness of the friction between the silicone sleeve and the penis according to needs, improve the stimulation effect on the penis, and thus improve the semen collection efficiency of the device.

[0011] In one embodiment, the driving assembly includes a rotating sleeve, an inner gear ring and a gear; the outer wall of the semen collection tube is provided with a clearance ring groove, one end of the multiple sets of rotating shafts all extend into the clearance ring groove, and are all coaxially connected with the gears; the rotating sleeve is rotatably mounted on the semen collection tube, and one end of the rotating sleeve is provided with the inner gear ring, and the multiple sets of gears are meshed with the inner gear ring. When the semen collection tube is held and moved back and forth repeatedly to make the silicone sleeve rub the penis, the rotating sleeve is moved back and forth by fingers, and the reciprocating rotation of the rotating sleeve drives the reciprocating rotation of the inner gear ring. The reciprocating rotation of the inner gear ring meshes with the multiple sets of gears to drive the multiple sets of rotating shafts to reciprocate synchronously. The synchronous reciprocating rotation of the multiple sets of rotating shafts can cause the multiple sets of pressing blocks to squeeze the outer wall of the silicone sleeve or cancel the squeezing of the outer wall of the silicone sleeve, which is convenient for adjusting the tightness of the friction between the silicone sleeve and the penis while rubbing the penis, thereby improving the practicality of the device.

[0012] In one embodiment, the outer wall of the sperm collecting tube is provided with a fixed ring groove, and the other end of the rotating sleeve is provided with a fixed ring, and the fixed ring is rotatably arranged in the fixed ring groove.

[0015] In one embodiment, the inner wall of the silicone sleeve is provided with multiple groups of spherical protrusions at intervals. The multiple groups of spherical protrusions can improve the friction effect of the silicone sleeve on the user's penis.

[0016] In one embodiment, it further includes a collection mechanism, which includes a collection sleeve and a collection bottle. The collection sleeve is arranged in the semen collection cavity. The end of the collection sleeve close to the silicone sleeve is provided with a collection cavity, and the penis can be inserted into the collection cavity.
