Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to a sperm collection cup. BACKGROUND

[0002] In assisted reproductive technology, the main use of the sperm collection cup is to help men collect complete semen samples during semen examination. These cups are usually special tools provided by hospitals, designed to meet the needs of hygiene and portability. When using the sperm collection cup, patients need to follow the doctor's guidance to ensure that the sperm collection is carried out in a proper environment, and personal hygiene should be paid attention to, such as washing hands before use, to avoid contaminating the semen sample.

[0003] In actual work, there are often gel-like impurities and clots in semen. Such impurities and clots not only do not contain a mirror, but also easily affect the subsequent centrifugation effect and detection effect, causing certain influence on sperm detection and extraction. At present, a sperm collection cup with a filter function is designed on the market, but the filter screen on the partition only provides one-time filtering effect. When using a centrifuge to separate, it takes a certain time to suck the semen, and as the operation time increases, the separation effect decreases, affecting the detection effect.

[0004] In addition, if the semen in the sperm collection cup needs to be moved to a culture dish or observation dish, the sperm collection cup needs to be tilted to pour the semen out. During the pouring process, impurities and clots may be poured out by mistake, causing re-mixing and affecting the sperm collection effect.

[0005] Therefore, how to design a sperm collection cup that can solve the above technical problems is a technical problem to be solved. UTILITY MODEL CONTENTS

[0008] A first connecting pipe is provided on the second filter screen, and a first internal thread matched with the screw rod is provided in the first connecting pipe.

[0009] The liquid containing cup is provided with a liquid outlet at the bottom, and a sealing plug is detachably arranged on the liquid outlet

[0010] Further, the mesh number of the third filter screen is greater than that of the second filter screen, and the mesh number of the second filter screen is greater than that of the first filter screen.

[0014] Further, the sealing plug is connected with the liquid outlet through interference fit, and the bottom surface of the sealing plug is flush with the bottom surface of the liquid containing cup.

[0015] Further, a rotating member is fixedly arranged at the top end of the screw rod to facilitate rotation of the screw rod.

[0016] Further, the bottom surface of the liquid containing cup is provided with a slot, and the bottom end of the screw rod is fixedly provided with an anti-dropping block arranged in the slot.

[0017] The utility model has the following beneficial effects:

[0018] 1.

[0019] 2. The utility model discloses a liquid containing cup detachably connected with the connecting bucket, which is convenient for using a Paste suction tube to suck the sperm from the cup opening after centrifugation, or pouring out the filtered sperm from the cup opening or the liquid outlet according to needs, compared with the prior art sperm collecting cup that can only use a Paste suction tube to suck the sperm, the bottom sperm cannot be completely sucked, and the sperm and impurities are mixed again, which causes detection error, and the utility model has high detection precision and strong practicality.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] See Figure 1 As shown, the device includes a connecting bucket 1, a liquid-holding cup 2 detachably connected to the bottom of the connecting bucket 1, a connecting cover detachably disposed on the top of the connecting bucket 1, a sealing cover 4 detachably disposed on the top of the connecting cover, a first filter screen 5 fixed inside the connecting bucket 1, a screw 6 whose bottom end passes through the connecting cover and the first filter screen 5 and extends into the bottom of the liquid-holding cup 2, and a second filter screen 7 movably disposed inside the liquid-holding cup 2, matching the shape and size of the liquid-holding cup 2 and threaded onto the screw 6; the top diameter of the connecting bucket 1 is larger than the bottom diameter, which facilitates the collection of semen.

[0031] The second filter screen 7 is provided with a first connecting pipe 71, and the first connecting pipe 71 is provided with a first internal thread 711 that cooperates with the screw 6.

[0032] The first filter screen 5 is provided with a first connecting pipe 71 and the first connecting pipe 71 is provided with a first internal thread 711 that cooperates with the screw 6; the second filter screen 7 is provided with a second connecting pipe and the second connecting pipe is provided with a second internal thread 711 that cooperates with the screw 6.

[0033] The liquid cup 2 has a liquid outlet 21 at the bottom and a detachable sealing plug 211 on the liquid outlet 21; a third filter screen 212 is provided inside the liquid outlet 21.

[0034] Furthermore, the mesh count of the third filter 212 is greater than that of the second filter 7, and the mesh count of the second filter 7 is greater than that of the first filter 5.

[0035] Furthermore, a connecting groove 11 is formed around the upper end face of the top edge of the connecting bucket 1, and a connecting flange 31 is provided at the bottom of the connecting cover to cooperate with the connecting groove 11. The connecting cover and the connecting bucket 1 are connected by insertion.

[0036] Furthermore, the connecting cover 3 and the sealing cover 4 are threaded together, and the liquid cup 2 and the connecting hopper 1 are threaded together.

[0037] Furthermore, the inner wall of the liquid-holding cup 2 is flush with the inner wall of the connecting bucket 1.

[0038] Furthermore, the sealing plug 211 is connected to the liquid outlet 21 by an interference fit, and the bottom surface of the sealing plug 211 is flush with the bottom surface of the liquid cup 2, so that the liquid cup 2 can be placed on the table.

[0039] Furthermore, a rotating component 61 is fixed at the top of the screw 6 to facilitate the rotation of the screw 6.

[0040] Furthermore, a slot 22 is provided on the bottom surface of the liquid-holding cup 2, and an anti-detachment block 62 is fixed at the bottom end of the screw 6 and is located in the slot 22. This allows the second filter screen 7 to be dislodged.

[0041] The working principle is roughly as follows:

[0042] When collecting semen, remove the connecting cap and sealing cap 4. When collecting semen, the semen enters the liquid cup 2 through the first filter screen 5 for the first filtration. After the semen collection is completed, and the sealing cap 4 and the connecting cap are connected to the connecting bucket 1 in sequence, place it in a centrifuge for centrifugation. After centrifugation, rotate the screw 6 to move the second filter screen 7 upward to perform a second filtration on the centrifuged semen.

[0043] At this point, the connecting bucket 1 can be separated from the liquid cup 2, and a pipette can be used to draw the liquid. Alternatively, the sealing plug 211 can be removed as needed to allow the semen to pass through the third sieve for a third filtration. The sealing plug 211 can then be moved into the observation dish for further processing.
