Description

Technical Field

[0001] This application relates to the field of live oocyte retrieval technology, and more specifically, to a filtration device for filtering follicular fluid. Background Technology

[0002] Live oocyte retrieval is a technique that involves puncturing follicles in the ovaries of donor cows using ultrasound or endoscopy to extract follicular fluid and obtain oocytes. This technique is then combined with in vitro embryo production (IVF) technology to allow oocytes to mature in vitro, undergo in vitro fertilization to develop into blastocysts, and finally transfer the embryos to a recipient mother or cryopreserve them.

[0003] In practical applications, follicular fluid needs to be filtered to obtain oocytes. However, in existing technologies, a filter is generally used in conjunction with a collection tube for collecting the filtered waste liquid. That is, the filter is placed on the collection tube and needs to be held by the operator. This can easily cause the collection tube and filter to shake during the pouring of follicular fluid into the filter, resulting in the follicular fluid being poured out. Moreover, since the bottom diameter of the filter matches the top diameter of the collection tube without any gap between them, and the follicular fluid is viscous and contains blood clots, it is easy for the liquid to adhere and form a negative pressure environment with the collection tube. This can affect the filtration of follicular fluid, delay oocyte retrieval, and increase the risk of oocyte contamination.

[0004] Therefore, in order to overcome the shortcomings of the existing technology, there is a need to provide a filtration device for filtering follicular fluid. Utility Model Content

[0020] A second tube extends downward from the bottom of the first tube; the diameter of the second tube gradually decreases from the end near the first tube to the end away from the first tube.

[0022] Optionally, the diameter of the first placement hole is larger than the diameter of the third placement hole;

[0023] The diameter of the second placement hole is larger than the diameter of the third placement hole;

[0024] The diameter of the first placement hole is equal to the diameter of the second placement hole.

[0025] Optionally, the diameter of both the first placement hole and the second placement hole is 30mm to 32mm;

[0029] The beneficial effects of this application are as follows:

[0030] To address the problems existing in the current technology, this application provides a filtration device for filtering follicular fluid. The bottom of the collection tube passes through the first placement hole, the second placement hole, and the third placement hole in sequence, and is placed below the second partition. The top of the collection tube is located between the first partition and the top wall of the housing, at which point the collection tube is fixed in the inner cavity of the housing. The bottom of the filter passes through the first placement hole to the space between the first partition and the top wall of the housing, so that the bottom of the filter corresponds to the top of the collection tube. Follicular fluid is poured into the filter for filtration, and the filtered waste liquid is discharged from the bottom of the filter into the collection tube, thereby achieving the filtration of follicular fluid. The filtration device provided in this application supports the collection tube and filter through the top wall of the shell, the first partition, and the second partition. It eliminates the need for manual handling, keeping the collection tube and filter in a fixed position. This prevents the follicular fluid from shifting and spilling out during the pouring process due to shaking, thus avoiding waste. Furthermore, the bottom of the filter has a gap with the top of the collection tube, allowing the collection tube to communicate with the inner cavity of the shell. This ensures that the waste fluid filtered through the filter can be smoothly discharged into the collection tube. It also prevents the formation of a negative pressure environment within the collection tube due to the high viscosity of the follicular fluid, which could affect filtration. This improves the filtration efficiency of the follicular fluid, accelerates the oocyte retrieval process, reduces the risk of oocyte contamination, reduces the number of personnel required for oocyte retrieval, and lowers labor costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0039] It should also be noted that, in the description of this application, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] To address the problems existing in the prior art, one embodiment of this application provides a filtration device for filtering follicular fluid, such as... Figure 1-5As shown, it includes: a housing with an inner cavity; the housing includes a first side portion 13, which is open; the top wall 11 of the housing includes at least one first placement hole 15 extending from its top surface to its bottom surface; a first partition 2 and a second partition 3 inserted into the inner cavity of the housing through the open portion 13, the first partition 2 including at least one second placement hole 21 corresponding to the first placement hole 15 extending from its top surface to its bottom surface; the second partition 3 including at least one third placement hole 31 corresponding to the second placement hole 21 extending from its top surface to its bottom surface; and corresponding first placement holes 15 and second placement holes. The centers of the second placement hole 21 and the third placement hole 31 are on the same straight line; the collection tube located in the second placement hole 21 and the third placement hole 31 can be a 50ml centrifuge tube; the bottom of the collection tube is located below the second partition 3, and the top is located between the first partition 2 and the top wall 11 of the housing; a filter used in conjunction with the collection tube and located in the first placement hole 15; the bottom of the filter is located between the first partition 2 and the top wall 11 of the housing, and the top is located on the top surface of the top wall 11 of the housing; there is a gap between the filter and the collection tube, that is, there is a gap between the bottom of the filter and the top of the collection tube. Here, as... Figure 1 and 2 As shown, the first placement hole 15, the second placement hole 21 and the third placement hole 31 are each represented by two.

[0041] In the above embodiments of this application, the bottom of the collection tube passes through the first placement hole 15, the second placement hole 21, and the third placement hole 31 in sequence to the bottom of the second partition 3, and the top of the collection tube is located between the first partition 2 and the top wall 11 of the shell. At this time, the collection tube is fixed in the inner cavity of the shell. The bottom of the filter passes through the first placement hole 15 to the bottom of the first partition 2 and the top wall 11 of the shell. In this way, the bottom of the filter corresponds to the top of the collection tube. Follicular fluid is poured into the filter for filtration, and the filtered waste liquid is discharged from the bottom of the filter into the collection tube, thereby realizing the filtration of follicular fluid. The filtration device provided in this application supports the collection tube and filter through the top wall 11 of the shell, the first partition 2, and the second partition 3. It eliminates the need for manual handling, keeping the collection tube and filter in a fixed position. This prevents the follicular fluid from shifting and spilling out during the pouring process due to shaking, thus avoiding waste. Furthermore, the gap between the bottom of the filter and the top of the collection tube allows the collection tube to communicate with the inner cavity of the shell. This ensures that the waste fluid filtered through the filter can be smoothly discharged into the collection tube, preventing the formation of a negative pressure environment within the collection tube due to the high viscosity of the follicular fluid, which could affect filtration. This improves the filtration efficiency of the follicular fluid, accelerates the oocyte retrieval process, reduces the risk of oocyte contamination, reduces the number of personnel required for oocyte retrieval, and lowers labor costs.

[0042] In one specific embodiment, the housing further includes two arcuate edges 141, which are arranged on both sides of the first side portion 13. The housing has two opposing second sidewalls 14; the arcuate edge 141 is located on one side of the first side portion 13 and extends from the top wall 11 of the housing to the bottom wall 12 of the housing, and is recessed inward. The side length of the second sidewall 14 connected to the bottom wall 12 is preferably 120 mm, that is, the width of the housing is preferably 120 mm; the side length of the second sidewall 14 perpendicular to the bottom wall 12 is preferably 170 mm, that is, the height of the housing is preferably 170 mm; and the side length of the bottom wall 12 perpendicular to the second sidewall 14 is preferably 300 mm, that is, the width of the housing is preferably 300 mm.

[0043] The first partition 2 and the second partition 3 are located on the same arc surface as the two second side walls 14 located on the same arc surface as the first side 13. That is, the arc edge of the second side wall 14 is on the same arc surface as the first partition 2 and the second partition 3 located on the same arc surface as the first side 13. Since the collection tube needs to pass through the first placement hole 15 to the second placement hole 21 and the third placement hole 31, during the placement of the collection tube, the operator can insert the collection tube along the first placement hole 15 with their left hand. When the bottom of the collection tube reaches between the first partition 2 and the second partition 3, the right hand can reach between the first partition 2 and the second partition 3 through the opening of the first side 13 of the shell to allow the collection tube to be smoothly inserted into the third placement hole 31. The design that the two second side walls 14 are both arc edges 141 on the first side 13 means that the operator's hand will not be blocked by the shell when entering between the first partition 2 and the second partition 3, making the operation more convenient.

[0044] Specifically, the first partition 2 and the second partition 3 are both horizontal. This ensures that the collection tube is vertical, facilitating the filtration of follicular fluid.

[0045] In one specific embodiment, the first partition 2 further includes a plurality of first leakage holes 22 extending from its top surface to its bottom surface, and the plurality of first leakage holes 22 can be arranged in an array; the second partition 3 further includes a plurality of second leakage holes 32 extending from its top surface to its bottom surface, and the plurality of second leakage holes 32 can be arranged in an array. During the follicular fluid filtration process, there may be splashing of filtered waste fluid, which can flow to the bottom of the shell through the first leakage holes 22 and the second leakage holes 32. Further, the diameter of the first leakage hole 22 is smaller than the diameter of the second placement hole 21; the diameter of the second leakage hole 32 is smaller than the diameter of the third placement hole 31; thus, the collection tube will not be mistakenly inserted into the first leakage hole 22 or the second leakage hole 32 when it is inserted.

[0046] In one specific embodiment, the collecting tube includes a first tube body 41 and a second tube body 42 extending downward from the bottom of the first tube body 41; the diameter of the second tube body 42 gradually decreases from the end near the first tube body 41 to the end away from the first tube body 41. The diameter of the first placement hole 15 is larger than the diameter of the third placement hole 31, and the diameter of the second placement hole 21 is larger than the diameter of the third placement hole 31; the diameter of the first placement hole 15 is equal to the diameter of the second placement hole 21; thus, the second tube body 42 of the collecting tube can be installed in the third placement hole 31, thereby fixing the second tube body 42 and improving the stability of the collecting tube. Specifically, the diameter of the first placement hole 15 and the diameter of the second placement hole 21 are both 30mm to 32mm, preferably 31mm; the diameter of the third placement hole 31 is 9mm to 11mm, preferably 10mm.

[0047] In one specific embodiment, such as Figure 4 As shown, an inclined flow plate 6 is also provided in the inner cavity of the shell, located below the collection tube. Waste liquid flowing to the bottom of the shell through the first leakage hole 22 and the second leakage hole 32 flows onto the flow plate 6. The flow plate 6 has a wedge-shaped structure, with its top surface inclined in one direction. The inclined top surface of the flow plate 6 directs the waste liquid dripping onto its top surface in one direction. Specifically, a collector (not shown in the figure) for collecting waste liquid is provided on the side of the flow plate 6 inclined towards the bottom wall 12 of the shell. The waste liquid flows to the collector for cleaning. It is understood that the bottom of the shell has an opening 7 corresponding to the collector, allowing the waste liquid to flow to the collector.

[0048] In one specific embodiment, the filter includes a filter body 51 with an open top, and a filter screen at the bottom of the filter body 51 for filtering follicular fluid. Follicles can remain in the filter screen for easy collection by staff. The filter also includes a handle 52 connected to the outer wall of the filter body 51. Staff can place or remove the filter from the first placement hole 15 by holding the handle 52.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
