In assisted reproduction techniques, whether for intrauterine insemination or in vitro fertilization-embryo transfer tube infant techniques, where sperm and eggs are mixed in vitro for fertilization, the sperm must be washed upstream. Currently, a 15ml centrifuge tube is typically used as the sperm upstream tube. Before the upstream, 1-2ml of semen is added into a centrifuge tube, then culture solution is slowly added above the semen, or the culture solution is added firstly, then the semen is input below the culture solution by a straw, then the semen is incubated for one hour at the temperature of 37 ℃, and then the supernatant on the upper layer is sucked by the straw for subsequent use.
However, the existing supernatant fluid suction is realized by manually adjusting the extending depth of the suction pipe by an operator, and the situation of extending too deep can occur due to the lower precision of manual adjustment, so that the lower seminal plasma can be sucked by extending too deep, and the use of sperms is influenced.

As shown in fig. 1 and 2, a collecting device according to an embodiment of the present invention includes a collecting member and an adjusting member.
The collecting member 12 has a receiving cavity 122 and an opening 124 communicating with the receiving cavity 122, and the opening 124 is opened at an end of one end of the collecting member 12 in the first direction.
The adjusting member 14 is used for the absorption end of the absorption device to pass through and extend out of a preset length, and the adjusting member 14 is connected to the collecting member 12 in a reciprocating manner along a first direction so as to adjust the distance that the absorption end passes through the opening 124 and extends into the accommodating cavity 122;
wherein, the adjusting member 14 includes a plurality of fixing positions in the process of reciprocating along the first direction, and when the adjusting member 14 is located at any fixing position, the adjusting member 14 is fixed relative to the collecting member 12.
In particular, in actual use, the opening 124 of the collecting member 12 is directed vertically upwards, i.e. the first direction is a vertical direction.
By arranging the collecting device, the opening 124 of the collecting part 12 is arranged upwards, the supernatant is placed in the containing cavity 122, the seminal plasma is input to the bottom layer of the containing cavity 122, the supernatant can be layered after standing for a period of time, then the absorption end of the absorbing device penetrates through the adjusting part 14, the adjusting part 14 moves back and forth along the first direction to adjust the distance of the absorption end penetrating through the opening 124 and extending into the containing cavity 122, after the height of the layer where the supernatant is located is determined, the adjusting part 14 is moved to a certain fixed position according to the extending length of the absorption end, the fact that the absorption end penetrating through the adjusting part 14 extends into the layer where the supernatant is located at the preset depth is ensured, and then the absorbing device absorbs the supernatant through the absorption end.
Because the adjusting part 14 at the fixed position is fixed relative to the collecting part 12, and the length of the absorption end which passes through the adjusting part 14 and extends out is fixed, the absorption end which passes through the adjusting part 14 cannot extend into the containing cavity 122 along the first direction, the precision of the depth of the absorption end which extends into the supernatant can be effectively ensured, the problem of seminal plasma absorption is avoided, and the use of the follow-up sperms is convenient.
It should be noted that the reciprocating movement of the adjusting member 14 along the first direction can adjust the distance of the absorption end extending into the receiving cavity 122, so that the predetermined length is the length of the absorption end of the absorption device extending out towards the collecting member 12 after passing through the adjusting member 14, and the length is fixed, i.e. the absorption end cannot extend further after passing through the predetermined length of the adjusting member 14.
Meanwhile, the preset depth, namely the absorption end, extends into the layer where the supernatant is located, the seminal plasma cannot be absorbed at the absorption end with the preset depth, the supernatant can be absorbed as far as possible, and more supernatant is prevented from being left.
In some embodiments, the adjustment member 14 is threadably coupled to the collection member 12 such that the adjustment member 14 moves in a first direction during rotation about the axis of rotation. In this way, the adjusting member 14 can be moved in the first direction more conveniently to adjust the position of the adjusting member 14, and the adjusting member 14 can be fixed relative to the collecting member 12 only by stopping the rotation, and at this time, the adjusting member 14 can be regarded as being located at a fixed position.
Further, the end of the collecting member 12, which is provided with the opening 124, is externally threaded to enable the adjusting member 14 to be threadedly coupled to the collecting member 12. It will be understood that the end of the collecting member 12 at one end in the first direction is the end surface of the collecting member 12 at that end, whereas the end of the collecting member 12 in the first direction is the end surface of the collecting member 12 at that end and a part at a distance from it.
In practical applications, the adjusting member 14 further defines an
The central axis of the
Meanwhile, since the adjusting part 14 is in threaded connection with the collecting part 12, and the adjusting part 14 can move along the first direction when rotating due to the threaded connection, and the absorbing end passes through the adjusting
In some embodiments, the adjusting member 14 includes a moving portion 141 and an adjusting
Furthermore, the moving portion 141 has a plurality of fixing positions during the reciprocating movement along the first direction, and when the moving portion 141 is at any fixing position, the moving portion 141 is fixed relative to the collecting member 12, so that the adjusting

In some embodiments, the moving portion 141 and the adjusting
The end of the collecting member 12 with the opening 124 extends into the opening cavity through the opening, and the opening is located at the end of the moving portion 141 away from the adjusting
Meanwhile, in the adjusting process, the end of the collecting part 12, which is provided with the opening 124, is always located in the open cavity, the open cavity actually has a certain shielding effect on the opening 124, and external impurities can be prevented from entering the accommodating cavity 122 through the opening 124 to pollute the supernatant to a certain extent.
In practice, the open cavity is internally threaded to mate with external threads on the collecting member 12 to threadably couple the adjustment member 14 to the collecting member 12.
Specifically, the collector 12 has a cylindrical shape, the moving portion 141 has the same shape as the collector 12 and also has a cylindrical shape, and the adjusting
In some embodiments, the collecting device further includes a limiting member 16, the limiting member 16 is connected to the collecting member 12 in a reciprocating manner along a first direction, and the limiting member 16 includes a plurality of limiting positions during the reciprocating movement along the first direction, when the limiting member 16 is located at any one of the limiting positions, the limiting member 16 is fixed relative to the collecting member 12 and can abut against the adjusting member 14, so that the adjusting member 14 is fixed relative to the collecting member 12, thereby limiting the adjusting member 14 from moving towards the other end of the collecting member 12 away from the opening 124 along the first direction, and limiting the absorption end from continuing to extend into the receiving cavity 122.
It can be understood that the adjusting member 14 is screwed to the collecting member 12, and the collecting member 12 and the moving portion 141 are both cylindrical, so that the inner diameter of the moving portion 141 and the outer diameter of the collecting member 12 can be regarded as the same, that is, only the limiting member 16 is required to be disposed outside the collecting member 12, so that the moving portion 141 can be ensured to abut against the limiting member 16 during the movement process along the first direction, and the limiting member 16 can limit the movement thereof.
It should be noted that the fact that the adjusting member 14 is fixed relative to the collecting member 12 means that the adjusting member 14 is fixed relative to the collecting member 12 without human intervention, and the adjusting member 14 needs to be adjusted manually when moving to a fixed position. For example, the adjusting member 14 is screwed to the collecting member 12, the adjusting member 14 still has a plurality of fixed positions without the limiting member 16, and the adjusting member 14 is fixed relative to the collecting member 12 with the adjusting member 14 in the fixed position and without human intervention, and the limiting member 16 is set to ensure that the adjusting member 14 is stably in the fixed position.
Further, the limiting member 16 includes a locking state and a releasing state; when the limiting member 16 is in a locked state, the limiting member 16 is fixed relative to the collecting member 12; when the limiting member 16 is in a relaxed state, the limiting member 16 is reciprocally movable along a first direction relative to the collecting member 12.
Thus, the position of the adjusting member 14 when the absorption end extends into the layer of the supernatant by a predetermined depth can be calculated according to the predetermined length of the absorption end passing through the adjusting member 14 and extending out and the height of the layer of the supernatant in the supernatant, and the position of the limiting member 16 corresponding to the position can be calculated at the same time. Then, the position of the position limiting member 16 in the relaxed state is moved to a corresponding position, and the state of the position limiting member 16 is converted to a locking state, so that the position limiting member 16 is fixed relative to the collecting member 12, and then the adjusting member 14 is moved to abut against the position limiting member 16 and is limited by the position limiting member 16.
In some embodiments, the retaining member 16 has opposing first and second ends that are removably coupled. Thus, the position of the limiting member 16 can be adjusted by surrounding the limiting member 16 outside the collecting member 12, then connecting the first end and the second end together to bring the limiting member 16 into the locked state, and separating the first end and the second end to bring the limiting member 16 into the relaxed state.
Specifically, the first and second ends are connected in a manner similar to a snap. Of course, the connection between the first end and the second end may be other ways, for example, the limiting member 16 may be similar to a watch, and the limiting member 16 is fixed on the collecting member 12 in a way similar to a way that a watch is worn on a wrist, which is not limited herein.
Meanwhile, it should be noted that, in the above embodiment, the adjusting member 14 is screwed to the collecting member 12, but in other embodiments, the adjusting member 14 may be connected to the collecting member 12 by other methods, for example, the adjusting member 14 may be directly covered on the end of the collecting member 12 with the opening 124, and the adjusting member 14 may still be limited by the limiting member 16.
In addition, the structure of the moving part 141 may be other structures, and may be a moving plate, a sliding rail extending along the first direction is disposed on the outer side of the collecting part 12, a sliding block is fixedly disposed on the moving plate, the sliding block is slidably disposed on the sliding rail, and the limiting of the moving part 141 with respect to the collecting part 12 may also be achieved by the limiting part 16.
In some embodiments, the cylindrical collection member 12 has an outer diameter of at least 2.2 cm and an inner diameter of at least 2 cm to ensure a larger cross-sectional area and thus a larger contact area between seminal plasma and supernatant, resulting in an increased number of sperm upstream and improved recovery.
