[0039] The embodiment of the present application provides a medical sperm collection cup and a sperm collection cup combination containing the same, thereby solving the technical problems in the prior art that the sperm collection cup is prone to leakage when pouring semen into a centrifuge tube, and is inconvenient to operate and inefficient.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] like Figures 1 to 4 As shown, one or more embodiments of the present application provide a medical semen collection cup, which is used for a patient to collect a semen sample, and the semen collection cup includes:

[0042] A cup body 10, wherein a cup cavity for containing semen is formed therein, and a cup opening communicating with the cup cavity is formed at one end of the cup body 10;

[0043] The cup cover 20 includes a body 26 which is through-hole, and the body 26 is formed with a first end 21 and a second end 22, wherein the first end 21 is used to be detachably connected and communicated with the cup mouth, and the second end 22 is used to be connected and communicated with the centrifuge tube 50, and the cross-sectional area of ​​the body 26 gradually decreases from the first end 21 to the second end 22, so as to guide the semen in the cup cavity to flow into the centrifuge tube 50;

[0044] A sealing device is used to seal the cup cover 20 to seal the cup body 10, and the sealing device can be turned on when the cup cover 20 is connected to the centrifuge tube 50 (for example, the sealing device is separated from the cup cover 20 when the cup cover 20 is connected to the centrifuge tube 50), so that the cup body 10 and the centrifuge tube 50 are connected.

[0045] It can be known from the above description that the semen collection cup described in the embodiment of the present application is provided with a cup cover 20, one end of which is detachably connected and communicated with the cup body 10, and the other end can be connected and communicated with the centrifuge tube 50. When collecting semen, the cup cover 20 is removed, and after the semen collection is completed, the cup cover 20 is covered. Since the cup cover 20 is provided with a sealing device, the cup cover 20 can seal the cup body 10 to prevent the semen from volatilizing and being contaminated; when it is necessary to guide the semen in the cup body 10 into the centrifuge tube 50, the cup cover 20 is connected to the centrifuge tube 50 and connected. The sealing device is connected, and the cup body 10 and the centrifuge tube 50 are connected. At this time, the cup body 10 can be inverted to guide the semen in the cup body 10 into the centrifuge tube 50. Since the cross-sectional area of ​​the cup cover 20 gradually decreases from the first end 21 to the second end 22, it plays a guiding role, and the semen in the cup cavity can be conveniently and efficiently transferred to the centrifuge tube 50 without overflowing, which effectively solves the technical problems in the prior art that the semen collection cup is easy to leak when pouring semen into the centrifuge tube 50, and the operation is inconvenient and the efficiency is low.

[0046] Specifically, Figure 4 As shown, the body 26 of the cup cover 20 is funnel-shaped (eg, conical), which has the function of gathering semen and guiding the flow of semen.

[0047] In one embodiment of the present application, Figures 1 to 4 As shown, a finger ring 24 for inserting fingers is provided on the outer wall of the cup cover 20 .

[0048] Specifically, the semen collection cup is small and is easy to slip out of the hand when held. By providing the finger ring 24, a finger (such as the index finger) can be inserted, which can effectively prevent the semen collection cup from accidentally slipping out during operation. It is also more convenient to invert the semen collection cup to introduce the semen inside the centrifuge tube 50, thereby improving the controllability and safety of the semen collection cup.

[0049] In one embodiment of the present application, Figures 1 to 3 As shown, the semen collection cup also includes an insulation cup cover 60, and the insulation cup cover 60 is formed with an insulation cavity for the cup body 10 to be inserted, so that the insulation cup inserted therein can reduce heat loss. For example, the insulation cavity is cylindrical with one end open, and the size is adapted to the cup body 10 for the cup body 10 to be placed therein.

[0050] Specifically, semen should be taken out from the semen collection room of a clinical institution and tested to ensure that semen motility does not decrease. However, since some patients cannot take out semen in the semen collection room, they need to take it out at home and bring it back to the laboratory for testing. The semen taken out must be well preserved. If it cannot be properly preserved, many problems will arise. If the semen is stored at a low temperature, its motility will decrease, affecting the accuracy of semen testing. Therefore, by setting the insulation cup cover 60, the semen can be kept warm in cold weather to ensure that the motility does not decrease in the short term, while also avoiding semen collisions, etc., to ensure that the sperm test results are as accurate as possible.

[0051] In addition, the thermos cup cover 60 can be made of commonly used thermal insulation materials on the market, such as aluminum foil, PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride), fabric, etc., as long as it is suitable for the occasion, there is no limitation here.

[0052] In one embodiment of the present application, the second end 22 of the cup cover 20 is connected to a tubular guide tube 23 , the guide tube 23 is connected to the first end 21 and the second end 22 , and the guide tube 23 is used to connect the centrifuge tube 50 .

[0053] In the above embodiment, if Figures 1 to 3 As shown in Figures 5 to 8, the sealing device includes a piston 30, which is located in the guide tube 23 and has an interference fit with the inner wall of the guide tube 23 to seal the guide tube 23, thereby sealing the cup cover 20, and when the centrifuge tube 50 is inserted into the guide tube 23 to a predetermined depth, the centrifuge tube 50 can push the piston 30 into the cup cavity to separate from the guide tube 23, thereby connecting the cup body 10 and the centrifuge tube 50.

[0054] Specifically, the predetermined depth refers to the depth at which the centrifuge tube 50 is installed in place in the guide tube 23 .

[0055] In one embodiment of the present application, Figures 1 to 3 As shown, a pH test paper 31 is provided on the side of the piston 30 facing away from the cup cavity, so as to detect the pH value of the semen in the cup cavity.

[0056] Specifically, normal semen is weakly alkaline, with a pH value between 7.2 and 8.0. Semen is composed of sperm and seminal plasma. Sperm is produced by the testicles, and seminal plasma is secreted by the prostate, seminal vesicles and bulbourethral glands. Seminal plasma contains fructose and protein, which are nutrients for sperm. It also contains prostaglandins and some enzyme substances. If semen is too acidic or alkaline, it may affect the activity and function of sperm and may even cause sperm death. Therefore, by measuring the pH value of the semen in the cup cavity, the condition of the semen inside can be understood.

[0057] In the prior art, to measure the pH value of semen in the semen collection cup, it is necessary to open the cup cover 20 and insert a pH test paper, which is rather cumbersome. In the embodiment of the present application, the pH value is directly integrated on the piston 30. When the centrifuge tube 50 is inserted into the guide tube 23 and the piston 30 is pushed into the cup body 10, the pH test paper 31 will follow the piston 30 into the cup body 10 to realize measurement, which is very convenient.

[0058] In addition, the PH test paper 31 is arranged on the side of the piston 30 facing away from the cup cavity, which can prevent the PH test paper 31 from being damaged by moisture and becoming ineffective when facing the cup body 10 before use. When the centrifuge tube 50 is inserted into the guide tube 23 and the piston 30 is pushed into the cup body 10, the PH test paper 31 will follow the piston 30 into the cup body 10, and display the PH value of the semen after entering the cup body 10 to absorb the semen.

[0059] In addition, the piston 30 can be made of a lightweight material (with a density lower than that of semen) that can float on the semen. For example, the piston 30 can be made of polyurethane foam, polyethylene foam, and the like. In this way, when the cup body 10 is inverted to guide the semen out, the piston 30 can float on the side of the cup cavity close to the bottom of the cup to be as far away from the guide tube 23 as possible, thereby avoiding blocking the guide tube 23 and affecting the flow of semen into the centrifuge tube 50. The PH test paper 31 can be a mature product suitable for medical use on the market. The PH test paper can be bonded and fixed on the piston 30. At the same time, the cup body 10 and the funnel piston 30 are made of transparent materials to facilitate observation of the PH test paper 31 to obtain the PH value.

[0060] In one embodiment of the present application, a sealing film 40 is sealed on the tube mouth of the guide tube 23. The sealing film 40 and the piston 30 isolate the guide tube 23 to form a sealed cavity to store the pH test paper therein and further seal the cup cover 20.

[0061] Specifically, the sealed cavity can store the pH test paper therein, thereby preventing the pH test paper from becoming ineffective due to moisture. The sealing film 40 can be a commonly used sealing film 40 for packaging in the prior art, such as polypropylene (PP), polyethylene (PE) and polyester (PET), etc., which is sealed on the tube mouth of the guide tube 23 by a sealing machine and can be punctured under the action of an external force.

[0062] In one embodiment of the present application, Figures 1 to 8 As shown, a first internal thread 25 is provided on the inner wall of the first end 21 of the cup cover 20, and a first external thread 11 is provided on the outer wall of the cup body 10 near the cup mouth, and the cup cover 20 and the cup body 10 are detachably connected through the cooperation of the first internal thread 25 and the first external thread 11;

[0063] Specifically, the cup body 10 and the cup cover 20 are connected by threads, which is not only firmly and reliably connected, but also detachable and tightly connected, and can effectively prevent leakage at the connection.

[0064] The present application also provides a semen collection cup assembly, which is used for collecting semen samples from patients and can introduce the semen samples into a centrifuge tube 50 for subsequent testing. Figures 4 to 8 As shown, the semen collection cup combination includes the semen collection cup and the centrifuge tube 50, the centrifuge tube 50 is connected and communicated with the second end 22 of the cup cover 20, and the centrifuge tube 50 can conduct the sealing device, so that the cup body 10 and the centrifuge tube 50 are connected.

[0065] Furthermore, the centrifuge tube 50 passes through the sealing film 40 and is inserted into the guide tube 23 of the cup cover 20 to be connected and communicated with the cup cover 20 , and the piston 30 is pushed into the cup cavity to be connected and communicated with the guide tube 23 .

[0066] Furthermore, a second internal thread is provided on the inner wall of the guide tube 23, and a second external thread 51 is provided on the outer wall of the centrifuge tube 50. The centrifuge tube 50 is inserted into the guide tube 23, and the connection and communication are achieved through the thread cooperation between the second external thread 51 and the second internal thread.

[0067] Furthermore, a scale 52 is provided on the outer wall of the centrifuge tube 50 , and the scale 52 is used to measure the volume of semen entering the centrifuge tube 50 .

[0068] Specifically, in the prior art, in order to obtain the amount of semen, it is necessary to use an electronic scale to weigh the empty cup and the weight after the semen is collected, and the weight of the semen is obtained by the difference between the two weights, which is relatively cumbersome. In the embodiment of the present application, a scale 52 is directly set on the outer wall of the centrifuge tube 50, and the volume of the semen can be directly obtained by reading the scale 52 value, which is very convenient.

[0069] Generally speaking, the single collection volume of semen does not exceed 10 ml, and the maximum value of the scale 52 of the centrifuge tube 50 can be set to 12 ml to meet daily needs.

[0070] An exemplary use of the sperm collection cup assembly described in this application is as follows:

[0071] When collecting semen, the cup cover 20 is removed from the cup body 10 to collect semen. After the semen collection is completed, the cup cover 20 is covered;

[0072] When it is necessary to guide the semen in the cup body 10 into the centrifuge tube 50, the sealing film 40 is pierced, the centrifuge tube 50 is passed through the sealing film 40 and inserted into the guide tube 23, and the piston 30 is pushed into the cup cavity;

[0073] The cup body 10 is inverted, and the semen in the cup body 10 flows into the centrifuge tube 50, and the pH value on the pH test paper can be read at the same time.

[0074] The above process is simple, convenient, fast and efficient. Therefore, the semen collection cup and the semen collection cup combination described in the embodiment of the present application have a simple structure and low cost, can be made into a disposable product, and can be widely promoted and used.

[0075] It should be understood that although the terms "first", "second", etc. may be used herein to describe various units, these units should not be limited by these terms. These terms are used only to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit without departing from the scope of the exemplary embodiments.

They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0077] The above is only a preferred embodiment of the present application, and is not any formal or substantial limitation to the present application. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the method of the present application, and these improvements and supplements should also be regarded as the protection scope of the present utility model.
