The semen volume parameter has high accuracy and reduces the probability of error. However, the wide-mouthed funnel in the above-mentioned device is similar to a jelly cup with a too small mouth, and the device is not provided with a corresponding cover. When the device is tilted, the semen inside is easily spilled, resulting in incomplete sampling, which greatly affects the test results. Utility Model Content

[0004] In order to improve the problem that the large-mouthed funnel in the above-mentioned device is similar to a jelly cup, the cup mouth is too small, and the device is not provided with a corresponding cover, which easily causes the semen inside to leak when the device is tilted, resulting in incomplete sampling and greatly affecting the detection results, the utility model provides a split semen collector for in vitro fertilization.

[0005] The present application provides a split semen collector for in vitro fertilization, which adopts the following technical solution:

[0006] A split semen collector for in vitro fertilization comprises a collecting cup, a funnel cup is arranged at the top of the inner cavity of the collecting cup, internal threads are arranged at equal intervals on the upper end of the inner wall of the collecting cup, external threads are arranged at equal intervals on the lower end of the outer wall of the funnel cup, the collecting cup and the funnel cup are threadedly connected, a cover body is hinged on the top of the funnel cup, a connecting seat is installed on the top of the right side of the funnel cup, an insert block is connected to the right end of the bottom of the cover body, a slot is provided on the top of the connecting seat for plugging with the insert block, and a limiting component is provided on the side of the connecting seat away from the funnel cup.

[0007] By adopting the above technical solution, the user releases the fixing effect of the plug through the limit assembly, and then pulls the cover body to flip, and the cover body drives the plug block to separate from the slot, thereby opening the cover body and collecting the semen through the funnel cup. Under the action of gravity, the semen continues to move downward, and then continues to flow into the collection cup for storage. When the collection is completed, the cover body is closed, and the plug block is inserted into the slot.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The present application provides an embodiment: a split semen collector for in vitro fertilization, including a collection cup 3, a funnel cup 1 is arranged at the top of the inner cavity of the collection cup 3, semen is collected and stored through the collection cup 3, and a rubber pad 5 is fixedly connected to the bottom of the collection cup 3. The friction between the collection cup 3 and the desktop is increased, so that the collection cup 3 is more stable when placed.

[0030] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 A handle 4 is fixedly mounted on one side of the collection cup 3, and a rubber sleeve is fixedly sleeved on the outer wall of the handle 4. It is convenient for the user to hold the handle 4 and collect semen. The setting of the rubber sleeve increases the friction between the user's hand and the handle 4, and tries to avoid the hand slipping during the holding process. The outer side of the collection cup 3 is engraved with scale lines 8 at equal intervals. It is convenient to read the volume of semen through the scale lines 8.

[0031] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The upper end of the inner wall of the collecting cup 3 is provided with internal threads at equal intervals, and the lower end of the outer wall of the funnel cup 1 is provided with external threads at equal intervals. The collecting cup 3 and the funnel cup 1 are threadedly connected. The longitudinal section of the funnel cup 1 is a truncated cone structure, and the diameter of the bottom of the funnel cup 1 is smaller than the diameter of the top. This makes it easier to collect semen.

[0032] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 A filter screen 2 is horizontally installed at the bottom of the inner cavity of the funnel cup 1. The filter screen 2 is used to filter out the coagulated fat particles and unliquefied mucus in the semen, which is convenient for clinical and scientific researchers to analyze and study semen and reduce the probability of confusion. A cover body 7 is hinged on the top of the funnel cup 1, and a connecting seat 6 is installed on the top of the right side of the funnel cup 1. The right end of the bottom of the cover body 7 is fixedly connected to an insert block 9, and a slot 10 is provided on the top of the connecting seat 6 to be plugged with the insert block 9.

[0033] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 A limiting component 11 is provided on the side of the connecting seat 6 away from the funnel cup 1. The limiting component 11 includes a shell 1106. The shell 1106 is fixedly installed on the end of the connecting seat 6 away from the funnel cup 1. A mounting plate 1103 is slidably installed in the inner cavity of the shell 1106. A movable rod 1105 is fixedly connected to the end of the mounting plate 1103 away from the connecting seat 6. The end of the movable rod 1105 away from the mounting plate 1103 extends out of the shell 1106 and is fixedly installed with a pull plate 1107. A positioning spring 1104 is sleeved on the outer wall of the movable rod 1105. The positioning spring 1104 is located between the mounting plate 1103 and the inner wall of the shell 1106. The end of the mounting plate 1103 close to the funnel cup 1 is fixedly connected to the limiting rod 1102. A limiting hole 1101 for plugging and cooperating with the limiting rod 1102 is opened on the outer side of the plug block 9. When the cover body 7 needs to be opened, the pull plate 1107 is pulled outward, and the pull plate 1107 drives the mounting plate 1103 to move outward through the movable rod 1105 to compress the positioning spring 1104. When the mounting plate 1103 moves, it drives the limiting rod 1102 to move outward and separate from the limiting hole 1101, thereby releasing the fixing effect of the limiting rod 1102 on the plug 9.

[0034] Working principle: When using the collector, the user first pulls the pull plate 1107 outward, and the pull plate 1107 drives the mounting plate 1103 to move outward through the movable rod 1105 to squeeze the positioning spring 1104. When the mounting plate 1103 moves, it drives the limiting rod 1102 to move outward and separate from the limiting hole 1101, thereby releasing the fixing effect of the limiting rod 1102 on the plug 9.

[0035] Then, the cover body 7 is pulled to flip over, and the cover body 7 drives the plug block 9 to separate from the slot 10, thereby opening the cover body 7. At this time, the user holds the handle 4 and collects the semen through the funnel cup 1. Under the action of gravity, the semen continues to move downward. During the movement, it will be filtered by the filter net 2 to facilitate the removal of particles and unliquefied mucus in the semen, and then continue to flow into the collection cup 3 for storage.

[0036] When the collection is completed, close the cover body 7, at which time the plug block 9 is inserted into the slot 10, and then release the pull plate 1107. Under the elastic force of the positioning spring 1104, the limiting rod 1102 is again inserted into the limiting hole 1101, so that the plug block 9 can be locked by the limiting rod 1102, so that the connection between the plug block 9 and the slot 10 is tighter, and the connection between the cover body 7 and the funnel cup 1 is tighter, so as to avoid leakage of semen during storage. When the collector is not needed, since the funnel cup 1 and the collection cup 3 are threadedly connected, the funnel cup 1 and the collection cup 3 can be rotated apart, which is convenient for cleaning and disinfecting the inside of the funnel cup 1 and the collection cup 3, so as to facilitate reuse later.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
