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 adjusting hole 144, the adjusting hole 144 corresponds to the opening 124 in the first direction, the absorbing end passes through the adjusting hole 144 and extends out toward the collecting member 12 by a predetermined length, and a central axis of the adjusting hole 144 is parallel to the rotation axis.
The central axis of the adjusting hole 144 is parallel to the rotation axis, and according to the relationship between the lines, the central axis of the adjusting hole 144 and the rotation axis are not coincident, so that the adjusting hole 144 on the adjusting member 14 rotates around the rotation axis in the process of rotating the adjusting member 14 around the rotation axis.
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 hole 144, the absorbing end can rotate around the rotating axis, so that the adjusting part 14 is driven to rotate around the rotating axis, and the adjusting part 14 can rotate along the first direction, thereby facilitating adjustment.
In some embodiments, the adjusting member 14 includes a moving portion 141 and an adjusting portion 143 connected to each other, the moving portion 141 is connected to the collecting member 12 in a reciprocating manner along the first direction, the adjusting portion 143 is movable toward or away from an end of the collecting member 12 where the opening 124 is opened along with the moving portion 141 in the reciprocating manner along the first direction, and the adjusting portion 143 is used for the absorption end to pass through and extend out by a predetermined length.
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 portion 143 is not driven to approach the end of the collecting member 12 with the opening 124, i.e. the absorption end extending into the receiving cavity 122 is restricted from further extending.
In some embodiments, the adjusting holes 144 are opened in the adjusting portion 143, the adjusting holes 144 penetrate through the adjusting portion 143 along two opposite sides of the first direction, the adjusting holes 144 on the adjusting portion 143 correspond to the openings 124 in the first direction, and the absorbing end penetrates through the adjusting holes 144 and protrudes toward the collecting member 12 by a predetermined length.
In addition, compare in the degree of depth that the manual regulation straw stretched into of operating personnel, absorption end wears to establish regulation hole 144 and stretches out predetermined length towards collecting 12, can ensure that absorption end absorbs the in-process and can not take place the shake to avoid absorption end to stir supernatant and seminal plasma, further improve the precision of absorption.
In some embodiments, the moving portion 141 and the adjusting portion 143 enclose to form an open cavity having an opening, the opening is located at an end of the moving portion 141 away from the adjusting portion 143, an end of the collecting member 12 having the opening 124 passes through the opening and extends into the open cavity, and a length of the collecting member 12 extending into the open cavity varies with movement of the adjusting member 14.
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 portion 143, so that when the moving portion 141 moves on the collecting member 12 in the first direction, the distance between the adjusting portion 143 and the end with the opening 124 can be adjusted, thereby adjusting the distance that the absorbing end extends into the accommodating cavity 122.
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 portion 143 has a circular plate shape, and the female screw is opened in the inner wall of the moving portion 141.
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.

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.
