Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a male semen specimen collection device. Background Art

[0002] Semen refers to the fluid that is ejected from the urethra of male animals or human males during ejaculation (usually in a state of orgasm). Normal semen is a viscous liquid mixture composed of sperm and seminal plasma, with seminal plasma accounting for more than 90% of the volume of semen. Sperm is produced by the testicles, matures in the epididymis, and is discharged through the vas deferens. Seminal plasma is mainly a mixture of secretions from accessory glands such as the prostate, seminal vesicles, and bulbourethral glands, and also includes a small amount of testicular fluid, epididymal fluid, etc. In addition to a large amount of water, fructose, protein, and polypeptides, seminal plasma also contains a variety of other sugars (such as glucose), enzymes (such as prostaglandins), inorganic salts, and small organic molecules, which can provide nutrition and energy for sperm. Normally, the components of sperm and seminal plasma "stay in their respective places". During the ejaculation process, sperm and seminal plasma mix to form semen.

[0003] The quality of semen specimens is related to the reliability of semen examination results. Currently, there is no special device for collecting semen specimens, and substitutes have defects such as poor controllability of specimen collection, easy leakage, contamination, and unsanitary conditions.

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Please also refer to Figures 1 to 4 The male semen specimen collection device according to the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, the male semen specimen collection device includes a film sleeve 1 and a collecting tube 2 connected to the film sleeve 1 by a thread 4. The film sleeve 1 is elastic at the end away from the collecting tube 2, and an annular tube 3 is fixed near the end of the collecting tube 2. The outer side of the annular tube 3 is provided with a thread 4. A connecting tube 5 is fixed to the top of the collecting tube 2. The connecting tube 5 is connected to the thread 4 of the annular tube 3. An opening 7 for connecting to the annular tube 3 is provided at the top of the collecting tube 2. A cover plate 6 is rotatably connected to the inside of the collecting tube 2, and the cover plate 6 covers the opening 7. The inner walls of the film sleeve 1, the annular tube 3 and the connecting tube 5 are coated with a hydrophobic film.

[0023] The annular tube 3 is made of polyethylene material and has a certain hardness.

[0024] Among them, the collecting tube 2 is made of the same material as the existing disposable test tube and is transparent. The bottom of the collecting tube 2 is conical. A metering rod 8 is fixed to the bottom of the collecting tube 2. A scale bar is provided on the side of the metering rod 8. The metering rod 8 is integrated with the collecting tube 2. The scale bar thereon is the scale value in the height direction. After the collecting tube 2 is left to stand, the amount of semen at the bottom of the collecting tube 2 can be observed.

[0025] A convex mirror 9 is further embedded in the side surface of the collecting tube 2 near the bottom end. Through the magnifying effect of the convex mirror 9, the liquefaction of semen can be better observed, so as to record the liquefaction time, and observe the semen color and the above-mentioned sperm amount.

[0026] As an embodiment, the cover plate 6 is rotatably connected to a cross bar 10 near the inner wall end of the collecting tube 2, and both ends of the cross bar 10 are fixed on the inner wall of the collecting tube 2. A torsion spring 11 is sleeved on the outside of the cross bar 10, and one end of the torsion spring 11 is fixed to the inner wall of the collecting tube 2, and the other end is fixed to the side of the cover plate 6.

[0027] A telescopic rubber tube 12 is fixed on the top wall of the collecting tube 2 , and the radius of the telescopic rubber tube 12 is greater than the radius of the opening 7 .

[0028] At the same time, a resistance plate 13 is fixed to the end of the annular tube 3 away from the film sleeve 1, and the resistance plate 13 is arranged in an arc shape.

[0029] Then, after the annular tube 3 is connected to the threaded connection 4 of the connecting tube 5, the contact plate 13 at the bottom of the annular tube 3 enters the interior of the collecting tube 2 along the opening 7, and preferentially contacts the cover plate 6 to drive the cover plate 6 to rotate. At this time, the collected semen enters the interior of the collecting tube 2 along the film sleeve 1. After the annular tube 3 is screwed out, the cover plate 6 is automatically driven to reset under the rebound action of the torsion springs 11 on both sides. After resetting, the top of the cover plate 6 covers the opening 7, and the top of the cover plate 6 contacts the bottom of the telescopic rubber tube 12 to seal the opening 7.

[0030] In the utility model, when in use, the film sleeve 1 is connected to the inside of the connecting tube 5 through the thread 4 of the annular tube 3. After it is completely screwed in, the contact plate 13 at the bottom of the annular tube 3 drives the cover plate 6 to rotate. After the cover plate 6 rotates, the opening 7 is opened, and the elastic portion of the film sleeve 1 is sleeved to the outside of the glans to collect semen. After the semen is collected, it flows along the film sleeve 1 through the annular tube 3 and the connecting tube 5 into the inside of the collecting tube 2. After the collection is completed, the annular tube 3 is screwed out, and the cover plate 6 is reset to cover the bottom of the opening 7 under the action of the torsion spring 11, and at the same time contacts with the telescopic rubber plate to seal the opening 7.

[0031] Let the collection tube 2 stand still and observe the changes of semen.

[0032] In this embodiment, the hydrophobic membrane uses an ultra-high molecular weight polyethylene film, and the hydrophobic film is coated on the cover plate 6, thereby preventing semen from staying on the film sleeve 1, the annular tube 3 and the cover plate 6.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
