Description

Technical Field

[0001] This invention relates to the field of livestock breeding technology, specifically to a heating device for ensuring the temperature of an egg extraction and delivery tube. Background Technology

[0002] Animal follicles and oocytes are indispensable raw materials in animal research and experiments, and these materials are usually obtained through live oocyte collection. To reduce animal stress and ensure the smooth progress of oocyte collection, it is generally carried out in outdoor animal farms or animal housing areas. This environment is greatly affected by external factors, and prolonged exposure of follicular fluid and oocytes to this environment can significantly impact experimental research. Therefore, when performing live oocyte collection, to avoid direct exposure of follicular fluid and oocytes to room temperature, which can inhibit intracellular enzyme activity due to rapid temperature drop, heating equipment is often installed on the outside of the oocyte collection tube.

[0003] However, existing heating equipment still has the following technical problems in use:

[0004] The existing product is a resistance wire thermostatic heater, typically designed with a resistance wire installed inside a semi-enclosed conduit. When current flows through the resistance wire, it heats up. The resistance wire is located adjacent to the ovulation extraction tube, and its heating helps maintain a suitable temperature within the tube. The overall design logic is to use the temperature difference between the resistance wire and the ovulation extraction tube to offset heat loss from the fallopian tube's contact with the outside environment, thus ensuring temperature stability and follicle quality during the ovulation extraction process. However, because the existing product relies on heat transfer between the resistance wire and the fallopian tube, the contact area between them is relatively small, leading to situations where the resistance wire temperature is high while maintaining overall fallopian tube temperature stability.

[0005] Therefore, a heating device for ensuring the temperature of the egg extraction delivery tube is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a heating device for ensuring the temperature of the egg extraction delivery tube, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a heating device for ensuring the temperature of an egg extraction and delivery tube, comprising an electric heating water tank, an egg extraction tube, and an egg collection cup. A partition plate is horizontally fixed inside the electric heating water tank. An electric heating wire is fixed to the upper end of the partition plate. The interior of the electric heating water tank is divided into a water storage chamber and a control chamber by the partition plate. A control circuit board is fixed inside the control chamber. A power supply battery compartment is fixed to the lower side of the electric heating water tank. A temperature sensor is fixed to the left end of the inner wall of the water storage chamber.

[0008] The egg extraction tube is wrapped with a heating tube. A first connector and a second connector are fixed to the left side of the heating tube. A water circulation mechanism is provided at the left end of the first connector and the second connector.

[0009] Preferably, the electric heating water storage tank has a water inlet on its upper side, and the water inlet is internally threaded with an insulated end cap.

[0010] Preferably, the water circulation mechanism includes a water pump, which is fixed inside the control cavity. A water pump is fixed to the left end of the water pump, and the upper end of the water pump extends into the interior of the water storage cavity. A water outlet is fixed to the right end of the water pump, and an inlet pipe is connected and fixed to the upper end of the outlet pipe. The other end of the inlet pipe is connected and fixed to a first connector. An outlet pipe is connected and fixed to the side wall of the second connector, and the other end of the outlet pipe extends into the interior of the water storage cavity.

[0012] Preferably, the heating tube is made of silicone material and has an open sidewall.

[0013] Preferably, the side wall of the electrically heated water storage tank has evenly arranged heat dissipation holes at the front end of the control cavity.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This application addresses the issue of inconsistent fluid temperature within the egg extraction tube by maintaining a constant temperature (or within a certain temperature range) water flow, thereby reducing uneven heating and ensuring the quality of the egg extraction process.

[0024] A heating device for ensuring the temperature of an oocyte extraction tube includes an electric heating water tank 1, an oocyte extraction tube 2, and an oocyte collection cup 3. A partition plate 4 is horizontally fixed inside the electric heating water tank 1. An electric heating wire 5 is fixed at the upper end of the partition plate 4. The electric heating wire 5 can be controlled by a control circuit board 8 and a main control adjustment switch 20 to raise its temperature to a certain temperature. The interior of the electric heating water tank 1 is divided into a water storage chamber 6 and a control chamber 7 by the partition plate 4. The control circuit board 8 is fixed inside the control chamber 7. A power supply battery compartment 9 is fixed on the lower side of the electric heating water tank 1. A temperature sensor 10 is fixed on the left end of the inner wall of the water storage chamber 6. The temperature sensor 10 is used to monitor the temperature inside the water storage chamber 6, so that the operator can understand the water temperature in real time.

[0025] The outside of the oviduct 2 is wrapped with a heating tube 11. A first connector 12 and a second connector 13 are fixed on the left side of the heating tube 11. A water circulation mechanism is provided at the left end of the first connector 12 and the second connector 13. The warm water inside the water storage chamber 6 is discharged into the heating tube 11 through the water circulation mechanism and circulates to keep the follicular fluid and oocytes inside the oviduct 2 warm.

[0026] The upper side of the electric heating water storage tank 1 is provided with a water inlet, and the internal thread of the water inlet is connected to an insulated end cap 14.

[0027] The water circulation mechanism includes a water pump 15, which is fixed inside the control chamber 7. A water pump pipe 16 is fixed to the left end of the water pump 15, and the upper end of the water pump pipe 16 extends into the water storage chamber 6. A water outlet pipe 17 is fixed to the right end of the water pump 15, and an inlet pipe 18 is fixed to the upper end of the outlet pipe 17. The other end of the inlet pipe 18 is connected and fixed to the first connector 12. An outlet pipe 19 is fixed to the side wall of the second connector 13, and the other end of the outlet pipe 19 extends into the water storage chamber 6.

[0028] The electric heating wire 5, temperature sensor 10, and water pump 15 are all electrically connected to the control circuit board 8. A main control adjustment switch 20 is fixed on the front side of the electric heating water storage tank 1. The control circuit board 8 is electrically connected to the main control adjustment switch 20. The electric heating wire 5, temperature sensor 10, water pump 15, control circuit board 8, and main control adjustment switch 20 are all electrically connected to the power supply battery compartment 9.

[0029] The heating tube 11 is made of silicone and has an open sidewall, which makes it easy to directly install the heating tube 11 around the outside of the egg extraction tube 2.

[0030] The side wall of the electric heating water storage tank 1 is provided with evenly arranged heat dissipation holes at the front end of the control cavity 7, which facilitates heat dissipation of the electrical components inside the control cavity 7.

[0031] Working principle:

[0032] Before egg retrieval, assemble the egg retrieval tube 2 and the heating tube 11, and connect and fix the first connector 12 and the second connector 13 on the side wall of the heating tube 11 to the inlet pipe 18 and the outlet pipe 19. Turn on the heating function, and the battery pack inside the power battery compartment 9 provides current to the heating wire 5. The current flows through the heating wire 5, which heats up and transfers the heat to the water in the water storage chamber 6. When the water temperature in the water storage chamber 6 reaches the set value, the temperature sensor 10 sends a signal back to the control circuit board 8, illuminating a specific indicator light. Then, the water pump 15 can be turned on to draw water from the water storage chamber 6. The water flows through the suction pipe 16, the outlet pipe 17, and the inlet pipe 18 into the heating tube 11, and then flows back into the water storage chamber 6 through the outlet pipe 19. During the flow of water, the heat in the water is transferred to the eggs in the egg retrieval tube 2, thereby ensuring the viability of the retrieved eggs. After the egg retrieval is completed, turn off the power.

[0033] The water temperature in the water storage chamber 6 is set 1-2℃ higher than that in the oocyte extraction tube 2 to ensure a constant temperature in the oocyte extraction tube during the oocyte extraction process, thereby ensuring the viability and quality of the extracted oocytes.
