Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an oocyte collection device. Background Technology

[0002] In the field of modern assisted reproductive medicine, successful oocyte retrieval is the cornerstone of key steps such as in vitro fertilization and embryo culture. As the core medical device for obtaining oocytes, the performance, ease of operation, and safety of the oocyte retrieval device directly affect the success rate of the entire assisted reproductive process and the patient's experience.

[0003] Traditional oocyte retrieval devices typically consist of a retrieval needle, connecting tube, and collection tube. These devices have certain drawbacks in use. For example, during oocyte retrieval, components in the follicular fluid (such as cell debris and protein clots) can easily clog the retrieval needle and connecting tube. Once clogging occurs, the current procedure requires the doctor to remove the rubber stopper from the collection tube and then connect a flushing device to the tubing for backflushing. This process has several disadvantages. First, removing the rubber stopper exposes the relatively closed retrieval system to the external environment, significantly increasing the risk of bacterial and viral contamination. Oocytes are extremely sensitive to environmental conditions; even minor contamination can damage or kill oocytes, or affect subsequent fertilization and embryonic development, reducing the success rate of assisted reproduction. Second, repeatedly inserting and removing the rubber stopper and performing flushing operations requires the doctor to possess high skill and stability. Slight carelessness can lead to human error, such as excessive force causing tubing rupture or uneven flushing fluid pressure impacting the oocytes, further affecting oocyte quality and retrieval effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide an oocyte collection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oocyte collector, comprising a protective shell and a collection tube movably connected within the protective shell. An anti-slip airbag is fixed to the inner wall of the protective shell. A rubber stopper is inserted into the upper half of the collection tube, and an adjustment box is fixed to the surface of the rubber stopper. A threaded rod is rotatably connected within the adjustment box, and an adjustment block is threadedly connected to the outer wall of the threaded rod. A connecting tube and a discharge tube are fixed to the upper and lower ends of the adjustment box, respectively. A guide hole communicating with the connecting tube and the discharge tube is opened on the adjustment block. The discharge end of the discharge tube is close to the inner wall of the collection tube. A suction tube is inserted into the connecting tube. A negative pressure tube is provided inside the rubber stopper, and an air suction hood is fixed to one end of the negative pressure tube inside the collection tube. Two baffles are arranged parallel to each other inside the air suction hood. A heating seat is installed on the bottom wall of the inner cavity of the protective shell.

[0006] In a further embodiment, a handle is fixed to one end of the suction tube, and an egg retrieval needle is fixed to the other end of the handle. A groove is provided on one side of the outer wall of the handle, and the tip of the egg retrieval needle is aligned with the direction of the groove.

[0007] In a further embodiment, a knob is fixed on the end face of the threaded rod located outside the adjustment box, and multiple rotating grooves are provided on both outer walls of the adjustment block, with limiting balls rolling in the rotating grooves. Limiting grooves for the limiting balls to slide are provided on both inner walls of the adjustment box.

[0008] In a further embodiment, an air inlet is provided on one side of the outer wall of the protective shell, and a vent pipe connected to the anti-slip airbag is installed in the air inlet, and a control valve is installed on the vent pipe.

[0009] In a further embodiment, the upper and lower outer walls of the adjusting block are provided with moving grooves for the connecting pipe and the discharge pipe to move, and sealing rings are provided at the positions where the connecting pipe and the discharge pipe contact the adjusting block.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This oocyte collector uses a threaded rod inside the adjustment box to move the adjustment block. The misalignment of the guide hole can seal the discharge tube. The suction tube can be disassembled without removing the rubber stopper. A syringe can be connected to the connector for reverse flushing, avoiding the risk of contamination and human error caused by removing the rubber stopper in traditional operations.

[0012] The anti-slip airbags on the inner wall of the protective shell can be inflated through the vent tube to tightly wrap the collection tube. This not only fixes the position of the collection tube, but also works with the protective shell to provide comprehensive protection for the collection tube, preventing damage to the collection tube due to accidental collisions.

[0013] The groove on the handle is aligned with the direction of the needle tip of the egg retrieval needle. The operator can visually judge the direction of the needle tip through the groove, which reduces the difficulty of the puncture operation, improves accuracy, and reduces the risk of damage to the tissues around the ovary.

[0014] The discharge end of the discharge tube is close to the inner wall of the collection tube, which can guide the oocytes to flow along the tube wall and buffer the impact of negative pressure. The parallel baffles in the suction hood can prevent cell debris from entering the negative pressure tube, reduce the probability of tube blockage, and protect the quality of oocytes. This oocyte collector solves the problem of contamination and errors caused by tube blockage in existing collectors, and improves the accuracy and safety of oocyte collection.

Detailed Implementation

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0024] This utility model provides, for example Figure 1-4The oocyte collection device shown includes a protective shell 1 and a collection tube 4 movably connected inside the protective shell 1. An anti-slip airbag 2 is fixed to the inner wall of the protective shell 1. The collection tube 4 is movably connected to the anti-slip airbag 2, and the anti-slip surface of the anti-slip airbag 2 is in contact with the outer wall of the collection tube 4. An air inlet is provided on one side of the outer wall of the protective shell 1, and a venting pipe 3 connected to the anti-slip airbag 2 is installed inside the air inlet. A control valve is installed on the venting pipe 3, and air is inflated into the anti-slip airbag 2 through the venting pipe 3, causing it to tightly enclose the airbag. The collecting tube 4 not only fixes the position of the collecting tube 4, but also, together with the protective shell 1, can provide comprehensive protection for the collecting tube 4 to prevent damage to the collecting tube 4 due to accidents. The bottom wall of the inner cavity of the protective shell 1 is equipped with a heating seat 19, which has an electric heating wire inside. The heating temperature of the heating seat 19 is adjustable and has a constant temperature function. The collecting tube 4 can be heated by the heating seat 19 to keep it at a constant temperature. The outer wall of the protective shell 1 is equipped with a control button for controlling the heating seat 19.

[0025] A rubber stopper 5 is inserted into the upper half of the collecting tube 4, and an adjusting box 6 is fixed on the surface of the rubber stopper 5. A threaded rod 8 is rotatably connected to the adjusting box 6 through a bearing. An adjusting block 9 is threadedly connected to the outer wall of the threaded rod 8. A threaded hole matching the threaded rod 8 is opened in the adjusting block 9. When the threaded rod 8 is rotated, the adjusting block 9 can move outside the threaded rod 8. A knob 7 is fixed on the end face of the threaded rod 8 outside the adjusting box 6. Multiple rotating grooves are opened on both sides of the outer wall of the adjusting block 9, and a limiting ball 10 is rolled in the rotating groove. A limiting groove is opened on both sides of the inner wall of the adjusting box 6 for the limiting ball 10 to slide. The limiting ball 10 slides in the limiting groove, which can limit the movement path of the adjusting block 9 and make the adjusting block 9 move more smoothly in the adjusting box 6.

[0026] The upper and lower ends of the adjusting box 6 are respectively fixed with a connecting pipe 11 and a discharge pipe 15. The adjusting block 9 has a guide hole that communicates with the connecting pipe 11 and the discharge pipe 15. The upper and lower outer walls of the adjusting block 9 are provided with moving grooves for the connecting pipe 11 and the discharge pipe 15 to move. Sealing rings are provided at the contact points between the connecting pipe 11 and the discharge pipe 15 and the adjusting block 9 to ensure the sealing between the adjusting block 9 and the connecting pipe 11 and the discharge pipe 15. A suction pipe 12 is inserted into the connecting pipe 11. A handle 13 is fixed to one end of the suction pipe 12, and the other end of the handle 13... One end is fixed with an oocyte retrieval needle 14, and a groove is provided on one side of the outer wall of the handle 13. The direction of the needle tip of the oocyte retrieval needle 14 is aligned with the direction of the groove. Through the corresponding design of the groove and the needle tip of the handle 13, the operator can easily judge the direction of the needle tip, which reduces the difficulty of operation, improves the accuracy of puncture, and reduces the risk of damage to surrounding tissues. The discharge end of the discharge tube 15 is close to the inner wall of the collection tube 4. This structural design can guide the oocytes and make them flow along the wall of the collection tube 4 to the bottom of the collection tube 4, which can better protect the oocytes from excessive impact of negative pressure.

[0027] A negative pressure tube 16 is installed inside the rubber stopper 5, and an air suction hood 17 is fixed to one end of the negative pressure tube 16 inside the collection tube 4. Two baffles 18 are arranged in parallel inside the air suction hood 17. The baffles 18 can block cell debris and prevent cell debris from being sucked into the negative pressure tube 16 through the air suction hood 17. When the suction tube 12 is blocked, the threaded rod 8 is rotated by the knob 7, which drives the adjusting block 9 to move. This causes the guide hole on the adjusting block 9 to be misaligned with the connecting tube 11 and the discharge tube 15, which can seal the discharge tube 15. Then the suction tube 12 can be directly removed and connected to the syringe through the connector to achieve reverse flushing. This design avoids the risk of contamination and human error caused by pulling out the rubber stopper 5 in the traditional method, and can quickly and effectively solve the tube blockage problem.

[0030] Working principle:

[0031] When using this oocyte collection device, the anti-slip airbag 2 is first inflated through the air tube 3 to fix the collection tube 4 inside the protective shell 1. During oocyte retrieval, the operator determines the direction of the needle tip through the groove of the handle 13 and punctures the oocyte retrieval needle 14 into the follicle. The negative pressure tube 16 is connected to the external negative pressure equipment, and a negative pressure suction is formed through the suction hood 17. The oocytes, along with the follicular fluid, enter the regulating box 6 through the suction tube 12 and the connecting tube 11. They flow into the tube along the inner wall of the collection tube 4 through the guide hole and the discharge tube 15. The baffle 18 prevents cell debris from entering the negative pressure tube 16. If a blockage occurs, the knob 7 is turned to drive the threaded rod 8 to move the adjusting block 9. The guide hole is misaligned with the connecting tube 11 and the discharge tube 15 to seal the discharge tube 15. Then, the suction tube 12 is disassembled and a syringe is connected through the external connector for reverse flushing. After clearing the blockage, it can be reassembled for continued use.

[0032] 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.
