Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a sheep oocyte collection device. Background Technology

[0002] An oocyte is an oogonia that undergoes meiosis during oogenesis. It is divided into primary oocytes, secondary oocytes, and mature oocytes, which are produced after oogonia differentiation and DNA replication, and are the products of the first and second meiotic divisions, respectively.

[0003] Patent publication number CN203923193U discloses a device for collecting oocytes from livestock, comprising an air pump, a pressure-stabilizing water bottle, and a storage tube. The air pump is connected to the pressure-stabilizing water bottle via a pipeline to generate negative pressure within the device. The pressure-stabilizing water bottle is a sealed container not filled with water, and the air portion of the pressure-stabilizing water bottle is connected to the air pump and the storage tube via pipelines to stabilize the negative pressure generated by the air pump. The storage tube is a sealed container connected to the pressure-stabilizing water bottle via a pipeline, and is also connected to a pipette for aspirating animal oocytes and holding the animal oocytes.

[0004] To address the challenge of controlling suction in the pipette during laboratory oocyte collection from livestock, which can lead to cell leakage and compromise cell quality due to improper operation, current technology employs an air pump to create negative pressure within the device. The pipette is connected to a pressure-stabilizing bottle to maintain this pressure. A storage tube holds the animal oocytes and is connected to the pressure-stabilizing bottle. A pipette with a needle at the end of the pipette facilitates oocyte aspiration. The oocytes are then transferred from the pipette into the storage tube, completing the collection process. However, a recurrence exists where contaminants from the pipette between the air pump and the storage tube enter the storage tube after collection, contaminating the collected oocytes.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a sheep oocyte collection device, which employs a sealing mechanism, connecting tube, rubber ring, fixing ring, fixing plate, air hole one, support tube, return spring, sealing block, sealing gasket, connecting ring, air hole two, conversion head, and connecting hose one. The conversion head is connected to the connecting hose one, and the connecting hose one is connected to the collection device. The connection between the conversion head and the connecting tube facilitates cleaning of the inside of the connecting tube. The connecting tube, through the conversion head and connecting hose one, is connected to the collection device to seal the output end of the collection device, preventing contaminants from the external environment from entering the collection device. The connecting tube is connected to the support tube and return spring through the fixing plate, fixing the support tube and return spring.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a sheep oocyte collection device, including a syringe 1. A sealing mechanism 2 is provided at the input end of the syringe 1, and a collection mechanism 3 is provided at one end of the sealing mechanism 2. A collection mechanism 4 is provided at the input end of the collection mechanism 3. The sealing mechanism 2 includes a connecting tube 201. A rubber ring 202 is fixedly connected inside the top end of the connecting tube 201, and a fixing ring 203 is fixedly connected inside the top end of the connecting tube 201, located below the rubber ring 202. A fixing plate 204 is fixedly connected to the middle of the inner side of the connecting tube 201. An air hole 205 is opened on the top surface of the fixing plate 204, and a support tube 206 is fixedly connected to the top surface of the fixing plate 204. A return spring 207 is fixedly connected to the top surface of the fixed plate 204. The return spring 207 is sleeved on the side of the support tube 206. A sealing block 208 is fixedly connected to one end of the return spring 207. A sealing gasket 209 is fixedly connected to the upper side of the sealing block 208. The sealing block 208 and the sealing gasket 209 are movably connected to the bottom surface of the fixed ring 203. A connecting ring 210 is fixedly connected to the top surface of the sealing block 208. A second air hole 211 is opened on the side of the connecting ring 210. There are multiple air holes 211 and they are evenly distributed on the side of the connecting ring 210. A conversion head 212 is internally threaded to the bottom end of the connecting tube 201. A first connecting hose 213 is sleeved on the side of one end of the conversion head 212.

[0027] In this embodiment, by connecting the adapter 212 to the connecting hose 213 and then connecting the connecting hose 213 to the collection device, the adapter 212 is connected to the connecting pipe 201 for easy cleaning of the inside of the connecting pipe 201. The connecting pipe 201, through the adapter 212 and the connecting hose 213, is connected to the collection device to seal the output end of the collection device, preventing pollutants from the external environment from entering the collection device. The connecting pipe 201 is fixed by the support pipe 206 and the return spring 207 connected by the fixing plate 204. The support pipe 206 is connected to the return spring 207 to support the return spring 207. One end of the return spring 207 is connected to the sealing block 208, and the sealing block 208 is movably connected to the bottom surface of the fixing ring 203. The sealing block 208 and the fixing ring 203 cooperate to seal the inside of one end of the connecting pipe 201. The sealing gasket 209 and the sealing... The connection of the closing block 208 can improve the sealing performance of the connection between the closing block 208 and the fixing ring 203. When collecting oocytes from sheep, the input end of the syringe 1 is inserted into one end of the connecting tube 201. The rubber ring 202 contacts the input end of the syringe 1, improving the tightness of the connection between the syringe 1 and the connecting tube 201. Pushing the syringe 1 causes the input end of the syringe 1 to contact the connecting ring 210 and causes the connecting ring 210 to descend. When the connecting ring 210 descends, it causes the closing block 208, the sealing gasket 209 and the fixing ring 203 to separate, thereby connecting the two ends inside the connecting tube 201. When the closing block 208 descends, it causes the return spring 207 to contract, pulling the needle of the syringe 1 through the second air hole 211, the first air hole 205 and the first connecting tube 213 to extract the gas inside the collection device, creating a negative pressure inside the collection device. The collection device is connected to the collection device, which facilitates the collection of oocytes from sheep.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the collection mechanism 3 includes a collection tube 301, a rubber stopper 302 is movably connected to the top end of the collection tube 301, a connecting tube 303 is fixedly connected to the top surface of the rubber stopper 302, a connecting tube 304 is fixedly connected to the top surface of the rubber stopper 302, the top end of the connecting tube 303 is sleeved with a connecting hose 213, the bottom end of the connecting tube 303 is movably connected to the upper part of the inner cavity of the collection tube 301, and the bottom end of the connecting tube 304 is movably connected to the middle part of the inner cavity of the collection tube 301.

[0030] In this embodiment, the collection tube 301 is sealed by connecting the rubber stopper 302 to the collection tube 301. The rubber stopper 302 is connected to connecting tube one 303 and connecting tube two 304 to fix the connecting tube one 303 and connecting tube two 304. Connecting tube one 303 is connected to the sealing device, and connecting tube two 304 is connected to the collection device. The collection device inputs the oocytes into the collection tube 301 through connecting tube two 304. The length of connecting tube one 303 is shorter than that of connecting tube two 304 to prevent the oocytes from being sucked out of the collection tube 301 when the syringe 1 and the sealing device create negative pressure in the collection tube 301 through connecting tube one 303.

[0031] Example 3

[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the collection mechanism 4 includes a threaded cylinder 401, one end of which is internally threaded with a threaded egg-collecting needle 402, and the other end of the threaded cylinder 401 is sleeved with a connecting hose 403, one end of which is sleeved with a connecting pipe 304.

[0033] In this embodiment, when collecting oocytes from sheep, the two ends of the connecting tubing 403 are connected to the threaded cylinder 401 and the connecting tube 304, respectively. The threaded oocyte retrieval needle 402 is rotated to connect the threaded oocyte retrieval needle 402 to the connecting tubing 403. The threaded oocyte retrieval needle 402 is inserted into the sheep's body. The syringe 1 creates a negative pressure inside the collection device through the sealing device. The collection device is connected to the threaded cylinder 401 and the threaded oocyte retrieval needle 402 through the connecting tubing 403. The sheep's oocytes are drawn into the threaded oocyte retrieval needle 402 and enter the collection device through the threaded oocyte retrieval needle 402, the threaded cylinder 401, and the connecting tubing 403.

[0034] The working principle of this sheep oocyte collection device will be explained in detail below.

[0035] like Figure 1-5As shown, when collecting oocytes from sheep, the rubber stopper 302 is connected to the collection tube 301, the adapter 212 is connected to the connecting tube 201 and the first connecting hose 213, the first connecting hose 213 is connected to the first connecting tube 303, and the two ends of the second connecting hose 403 are connected to the threaded cylinder 401 and the second connecting tube 304, respectively. The threaded oocyte retrieval needle 402 is rotated to connect the threaded oocyte retrieval needle 402 to the second connecting hose 403. The input end of the syringe 1 is inserted into one end of the connecting tube 201, and the rubber ring 202 contacts the input end of the syringe 1, improving the tightness of the connection between the syringe 1 and the connecting tube 201. The connecting pipe 201 is fixed by the support pipe 206 and the return spring 207 connected by the fixing plate 204. The support pipe 206 is connected to the return spring 207 to support the return spring 207. One end of the return spring 207 is connected to the sealing block 208, and the sealing block 208 is movably connected to the bottom surface of the fixing ring 203. The sealing block 208, the sealing gasket 209 and the fixing ring 203 cooperate to seal the inside of one end of the connecting pipe 201. Pushing the syringe 1 causes the input end of the syringe 1 to contact the connecting ring 210 and cause the connecting ring 210 to descend. When the connecting ring 210 descends... The sealing block 208, sealing gasket 209, and fixing ring 203 are separated, thereby connecting the two ends of the connecting tube 201. The threaded oocyte retrieval needle 402 is inserted into the sheep's body. Pulling the plunger of the syringe 1 draws out the gas inside the collection tube 301 through the second air hole 211, the first air hole 205, the first connecting hose 213, and the first connecting tube 303, creating a negative pressure inside the collection tube 301. The collection tube 301 is connected to the threaded cylinder 401 and the threaded oocyte retrieval needle 402 through the second connecting hose 403. The sheep's oocytes are drawn into the threaded oocyte retrieval needle 402 and enter through the threaded cylinder 401 and the second connecting hose 403. The oocytes from the sheep are collected in the collection tube 301. After collection, the syringe 1 is withdrawn from the connecting tube 201, and the input end of the syringe 1 is separated from the connecting ring 210. The reset spring 207 relaxes, causing the sealing block 208 and the sealing pad 209 to rise and adhere to the bottom surface of the fixing ring 203. The sealing block 208, the sealing pad 209, and the fixing ring 203 seal the connecting tube 201, preventing external contaminants from entering the collection tube 301 through the connecting tube 201, the conversion head 212, the connecting hose 213, and the connecting tube 303, thus preventing contamination of the oocytes collected in the collection tube 301.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
