Abstract
Description
Technical Field
[0001] This utility model relates to the field of embryo transfer technology, specifically to an oral straw for embryo transfer. Background Technology
[0002] Embryo transfer, also known as fertilized egg transfer, refers to the technique of transferring an early embryo from a female animal, or an embryo obtained through in vitro fertilization or other methods, into another female animal of the same species and with the same physiological condition, so that it can continue to develop into a new individual.
[0003] Current technology often uses oral suction tubes for embryo transfer. The staff inhales through the suction tube, creating negative pressure throughout the tube. The embryo and the flushing fluid that is suctioned out along with it are drawn into the tube under this negative pressure. To ensure that the embryo is not inhaled into the staff's mouth, the suction tube is often equipped with a filter to intercept the embryo. While the filter can intercept the embryo, it often cannot intercept the flushing fluid. There is a risk that the staff may inhale the flushing fluid into their mouth, and there is also a risk that the embryo may be contaminated by the staff's saliva flowing into the tube. Summary of the Invention
[0004] The purpose of this invention is to address the problem that existing filters often fail to intercept the ovulation fluid, posing a risk that workers may inhale the ovulation fluid into their mouths. This invention provides an oral suction tube for embryo transfer.

[0006] By adopting the above technical solution, when the staff inhales the ovulation flushing fluid into the oral suction tube, the moisture-absorbing component can absorb and intercept the ovulation flushing fluid, thereby preventing the ovulation flushing fluid from being inhaled into the staff's mouth. At the same time, the moisture-absorbing component can intercept the saliva produced by the staff, preventing the saliva from flowing into the second tube and contaminating the embryo. The filter is used to separate the ovulation flushing fluid from the embryo, so that the embryo remains in the second tube, while the ovulation flushing fluid flows into the first tube.
[0007] Preferably, a one-way valve is installed on the second hose.
[0008] By adopting the above technical solution, the one-way valve enables the embryo to move in only one direction. After the embryo passes from the side of the one-way valve away from the second tubing to the side of the one-way valve facing the second tubing, the one-way valve closes, thus preventing the embryo from slipping out of the second tubing and the collection head.
[0009] Preferably, the moisture-absorbing element is one or more of cotton swabs, activated carbon rods, and sponge rods.
[0010] By adopting the above technical solutions, the moisture-absorbing component can ensure the absorption of flushing fluid or saliva while allowing normal air passage by using cotton swabs, activated carbon sticks, or sponge sticks alone. At the same time, two or three of the cotton swabs, activated carbon sticks, or sponge sticks can be combined. The cotton swabs can absorb the flushing fluid that is drawn up, the activated carbon sticks can absorb substances in the human exhaled air that are toxic to the embryo, and the sponge sticks can absorb the small amount of saliva carried out by the staff.
[0011] Preferably, the straw includes a connecting tube that snaps into the first flexible tube and an installation tube mounted on the connecting tube, the moisture-absorbing element is located inside the installation tube, the connecting tube is a tapered tube, and the installation tube is a cylindrical tube with openings at both ends.
[0012] By adopting the above technical solution, the connecting tube is designed as a tapered tube, which makes it easy to insert the connecting tube into the first flexible tube, thereby realizing the connection between the mouth suction tube and the first flexible tube. The installation tube is designed as a cylindrical tube, which makes it easy to install the moisture-absorbing component.
[0013] Preferably, a first isolation net is installed inside the straw.
[0014] By adopting the above technical solution, the first isolation net is used to support the moisture-absorbing component, thereby preventing the moisture-absorbing component from falling into the connecting pipe. At the same time, the first isolation net can facilitate the normal passage of gas and flushing fluid.
[0015] Preferably, the filter is a sterile needle filter.
[0016] By adopting the above technical solution, the sterile needle filter can ensure that the embryo is in a sterile environment during the transfer, and at the same time, it can separate the embryo from the flushing fluid.
[0017] Preferably, the straw is provided with a blocking element to prevent the absorbent element from being sucked out.
[0018] By adopting the above technical solution, the blocking component is used to fix the moisture-absorbing component inside the mouth straw, thereby preventing the moisture-absorbing component from being inhaled into the mouth by the staff.
[0019] Preferably, the blocking member includes a connecting part installed inside the straw, a handhold abutting against the side of the straw away from the first hose, and an air inlet opened on the handhold and passing through the connecting part, wherein a second isolation net is provided inside the air inlet.
[0020] By adopting the above technical solution, the connecting part is used to maintain the connection between the blocking part and the mouth straw, the hand-held part is used to facilitate the staff to hold the hand when installing the blocking part, the air inlet is used to facilitate the staff to inhale into the mouth straw, thereby creating negative pressure in the entire tube, and the second isolation net can block the moisture-absorbing part to prevent the moisture-absorbing part from entering the mouth under the staff's mouth suction.
[0021] Preferably, the blocking member is threaded or snapped into the straw.
[0022] By adopting the above technical solution, the blocking component can be threaded or snapped into the straw, thus enabling a detachable connection between the blocking component and the straw, making it convenient for staff to insert the absorbent component into the straw.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] The oral suction tube for embryo transfer has a moisture-absorbing component that can absorb and intercept the flushing fluid when the staff draws it into the tube, thus preventing the fluid from being drawn into the staff's mouth. At the same time, the moisture-absorbing component can also intercept the saliva produced by the staff, preventing it from flowing into the second tube and contaminating the embryo.
[0025] This oral straw for embryo transfer has a blocking component installed on it. This component can block the absorbent material inside the straw, thus preventing it from being accidentally inhaled into the mouth by the staff. By threading or snapping the blocking component into the straw, a detachable connection between the blocking component and the straw can be achieved, making it convenient for the staff to put the absorbent material into the straw.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1
[0031] Please refer to Figures 1 to 2 An oral suction tube for embryo transfer in this embodiment includes an oral suction tube 1, a first flexible tube 2 installed on the oral suction tube 1, a filter 3 installed at the end of the first flexible tube 2 away from the oral suction tube 1, a second flexible tube 5 installed at the end of the filter 3 away from the first flexible tube 2, a collection head 6 installed at the end of the second flexible tube 5 away from the filter 3, and a moisture-absorbing component 7 placed inside the oral suction tube 1.
[0032] In the above scheme, when the staff member draws the rinsing fluid into the oral suction tube 1, the absorbent component 7 can absorb and intercept the rinsing fluid, thereby preventing the rinsing fluid from being drawn into the staff member's mouth. At the same time, the absorbent component 7 can intercept the saliva produced by the staff member, preventing the saliva from flowing into the second tube 5 and contaminating the embryo. The filter 3 is used to separate the rinsing fluid from the embryo, so that the embryo remains in the second tube 5, while the rinsing fluid flows into the first tube 2.
[0033] In this embodiment, a one-way valve 4 is installed on the second hose 5, the moisture-absorbing element 7 is one of cotton swab 701, activated carbon swab 702 and sponge swab 703, and the filter 3 is a sterile needle filter.
[0034] In the above scheme, the moisture-absorbing component 7 can ensure the absorption of egg fluid or saliva and allow normal air passage by using cotton swabs 701, activated carbon swabs 702 or sponge swabs 703 alone.
[0035] The sterile needle filter ensures that the embryo is in a sterile environment during the transfer and can separate the embryo from the flushing fluid. The one-way valve 4 allows the embryo to move in only one direction. After the embryo passes from the side of the one-way valve 4 away from the second tubing 5 to the side of the one-way valve 4 facing the second tubing 5, the one-way valve 4 closes, thus preventing the embryo from slipping out of the second tubing 5 and the collection head 6.
[0036] In this embodiment, the mouth suction tube 1 includes a connecting tube 101 that is snapped into the first flexible tube 2 and an installation tube 102 installed on the connecting tube 101. The moisture-absorbing element 7 is located inside the installation tube 102. The connecting tube 101 is a tapered tube, and the installation tube 102 is a cylindrical tube with openings at both ends. A first isolation net 103 is installed inside the mouth suction tube 1. The first isolation net 103 is located at the connection between the connecting tube 101 and the installation tube 102.
[0037] In the above scheme, designing the connecting tube 101 as a tapered tube makes it easy to insert the connecting tube 101 into the first flexible tube 2, thereby realizing the connection between the suction tube 1 and the first flexible tube 2. The installation tube 102 is designed as a cylindrical tube to facilitate the insertion of the moisture-absorbing component 7. The first isolation net 103 is used to support the moisture-absorbing component 7, thereby preventing the moisture-absorbing component 7 from falling into the connecting tube 101. At the same time, the first isolation net 103 facilitates the normal passage of gas and flushing fluid.
[0038] It should be noted that when the first isolation net 103 is not installed inside the installation pipe 102, the moisture-absorbing component 7 will fall into the connecting pipe 101. However, since the connecting pipe 101 is a tapered pipe, the moisture-absorbing component 7 will not pass through the connecting pipe 101 and fall into the first flexible hose 2.
[0039] In this embodiment, the straw 1 is provided with a blocking member 8 to prevent the moisture-absorbing component 7 from being sucked out. The blocking member 8 includes a connecting part 801 installed in the straw 1, a handhold part 802 abutting against the side of the straw 1 away from the first hose 2, and an air inlet opened on the handhold part 802 and passing through the connecting part 801. A second isolation net 803 is provided in the air inlet. The blocking member 8 is threaded or snapped into the straw 1.
[0040] In the above scheme, the blocking member 8 is used to fix the moisture-absorbing member 7 inside the mouth straw 1, thereby preventing the moisture-absorbing member 7 from being inhaled into the mouth by the staff; the connecting part 801 is used to maintain the connection between the blocking member 8 and the mouth straw 1; the hand-held part 802 is used to facilitate the staff to hold the blocking member 8 when it is installed; the air inlet is used to facilitate the staff to inhale into the mouth straw 1, thereby creating a negative pressure in the entire tube; and the second isolation net 803 can block the moisture-absorbing member 7, preventing the moisture-absorbing member 7 from entering the mouth under the staff's mouth suction.
[0041] It should be noted that because the second isolation net 803 can block the moisture-absorbing component 7, the diameter of the air intake can be designed to be larger, making it easier for workers to inhale.
[0042] By threading or snapping the blocking member 8 into the straw 1, a detachable connection between the blocking member 8 and the straw 1 can be achieved, making it convenient for staff to insert the absorbent member 7 into the straw 1.
[0043] Operating procedure: When the absorbent component 7 needs to be installed, the blocking component 8 is removed from the suction tube 1, and the absorbent component 7 is installed into the suction tube 1. Then, the blocking component 8 is installed back onto the suction tube 1. When embryo transfer is required, the collection head 6 is aligned with the embryo. The operator inhales through the suction tube 1, creating negative pressure within the suction tube 1, the first tubing 2, the second tubing 5, and the collection head 6. Under this negative pressure, the one-way valve 4 opens, and the embryo and flushing fluid are drawn into the collection head 6. Then, the embryo and flushing fluid pass through the second tubing 5 and the one-way valve 6. When the embryo and the flushing fluid pass through the filter 3, the embryo remains in the second tubing 5, while the flushing fluid enters the first tubing 2. When the flushing fluid enters the oral suction tube 1, the absorbent component 7 inside the oral suction tube 1 absorbs and filters the flushing fluid, thereby preventing the flushing fluid from entering the worker's mouth. When the worker's saliva enters the oral suction tube 1, the absorbent component 7 can intercept the worker's saliva. When the worker stops inhaling, the one-way valve 4 closes, preventing the embryo from falling out of the one-way valve 4. Example 2
[0044] Please refer to Figure 3 The difference between this embodiment and Embodiment 1 is that the moisture-absorbing component 7 includes a sponge rod 703, an activated carbon rod 702, and a cotton rod 701 respectively disposed in the upper, middle, and lower layers.
[0045] The cotton swab 701 can absorb the egg flushing fluid that is drawn up, the activated charcoal swab 702 can absorb substances in human exhaled air that are toxic to the embryo, and the sponge swab 703 can absorb the small amount of saliva carried out by the staff. Since there is a lot of egg flushing fluid drawn up, there will be less saliva blown out by the staff. Therefore, the length of the cotton swab 701 can be designed to be longer than that of the sponge swab 703, for example, the ratio of the two can be set to 2:1.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
