Description

Technical Field

[0001] This utility model relates to the field of biological sample experimental equipment, and in particular to an embryo transfer device with physical locking function. Background Technology

[0002] In the process of assisted reproductive medical procedures, it is often necessary to obtain the patient's oocytes in the operating room, transfer the obtained oocytes to the embryo laboratory for fertilization and culture, and then transfer the patient's embryos to the operating room for embryo transfer to achieve pregnancy. Therefore, it involves the transportation and transfer of embryos, and ensuring the accuracy of embryo transfer is particularly important during the transportation and transfer process.

[0003] In existing technologies, since the operating room and the embryo laboratory are set up in two completely isolated spaces on opposite sides, when transferring embryos, a turntable or conveyor belt is usually set up to transfer the embryos from one side to the other. The storage and retrieval of embryos are both identified by the system program based on the label information on the sample. The system program is highly dependent on the system program. When the transfer device is operated simultaneously in the operating room and the embryo laboratory, it may lead to system identification errors, which may cause serious medical accidents.

[0004] Existing embryo transfer devices rely too heavily on the system, which carries a high risk of medical accidents when the system malfunctions in certain situations. Utility Model Content

[0006] An embryo transfer device with physical locking function is installed in an isolation cabinet located between the operating room and the embryo laboratory. The device includes a storage box and a transfer tray.

[0007] Both the storage box and the transmission disk are disc-shaped structures. The transmission disk is rotatably disposed inside the storage box. The transmission disk has multiple placement cavities along its circumference. The storage box has a first placement port and a second placement port corresponding to the placement cavities. The first placement port and the second placement port are located on both sides of the isolation cabinet. When the first placement port corresponds to one of the placement cavities, the second placement port is offset from the other placement cavities.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the device and isolation cabinet provided in this embodiment of the utility model; Figure 2 This is a schematic diagram of the overall structure of the device provided in this embodiment of the utility model; Figure 3 This is an exploded view of the device structure provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the sealing door switch structure provided in an embodiment of the present invention; Figure 5This is a cross-sectional schematic diagram of the sealing door switch structure provided in an embodiment of the present invention. An embryo transfer device with physical locking function is installed in an isolation cabinet 1, which is located between the operating room and the embryo laboratory. The isolation cabinet 1 includes a storage box 2 and a transmission disk 3. Both the storage box 2 and the transmission disk 3 are disc-shaped structures. The transmission disk 3 has multiple placement cavities 31 along its circumference. The storage box 2 has a first placement port 221 and a second placement port 222 corresponding to the placement cavities 31. The first placement port 221 and the second placement port 222 are located on both sides of the isolation cabinet 1. When the first placement port 221 corresponds to one of the placement cavities 31, the second placement port 222 is staggered from the other placement cavities 31.

[0026] Exemplarily, in this embodiment of the invention, a heating plate is also provided inside the placement cavity 31, and a temperature control device is also provided outside the device. The temperature control device is electrically connected to the heating plate and can control the heating plate inside the placement cavity 31 accordingly, so that the temperature inside the placement cavity 31 reaches a constant temperature level required for the culture and development of biological samples, ensuring their activity during the transfer and storage tape handling process. A gas supply path is also provided inside the placement cavity 31, and a gas supply control device is also provided outside the device. The gas supply control device is connected to the gas supply path and introduces a gas of a specified composition and concentration into the storage box 2 through the gas supply path to maintain a constant gas concentration level required for the culture and development of biological samples, ensuring their activity during the transfer and storage tape handling process. In this embodiment, the storage box 2 provides support for the transmission disk 3, allowing the transmission disk 3 to rotate within the storage box 2, so that the first placement port 221 and the second placement port 222 can correspond to the position of the placement cavity 31, allowing the operator to operate the placement cavity 31. Multiple placement cavities 31 can be provided on the transmission disk 3. Each placement cavity 31 is arranged at a certain angle on the circumference of the transmission disk 3. The first placement port 221 and the second placement port 222 are configured such that when the first placement port 221 corresponds to one of the placement cavities 31, the second placement port 222 is staggered from the other placement cavities 31. And when the second placement port 222 corresponds to one of the placement cavities 31, the first placement port 221 is staggered from the other placement cavities 31. This makes it impossible for the first placement port 221 and the second placement port 222 to correspond to the placement cavities 31 at the same time. This prevents the staff on both sides of the isolation cabinet 1 from operating on the embryos in the placement cavities 31 at the same time, thus avoiding medical accidents caused by system recognition errors when both sides operate at the same time. Compared to traditional technologies where the placement cavities and ports are symmetrically arranged and the placement ports on both sides correspond to two placement cavities simultaneously, the structure in this embodiment is designed such that when the first placement port 221 corresponds to one of the placement cavities 31, the second placement port 222 is staggered from the other placement cavities 31. This structurally prevents operators on both sides from operating the device simultaneously, thereby reducing the probability of medical accidents occurring with the device.

[0027] This utility model provides an embryo transfer device with a physical locking function. By setting a storage box 2 to support the transmission disk 3, the transmission disk 3 can rotate freely inside the storage box 2. By setting a first placement port 221 and a second placement port 222 that are staggered, when the first placement port 221 corresponds to one of the placement cavities 31, the second placement port 222 is staggered from the other placement cavities 311. This prevents staff on both sides of the isolation cabinet from operating on embryos in different placement cavities 31 at the same time, thereby preventing staff on both sides from performing embryo placement and retrieval work at the same time, eliminating the possibility of system recording errors, and effectively solving the problem of high risk of medical accidents in the prior art.

[0028] Optionally, multiple placement cavities 31 are evenly spaced along the circumference of the transmission disk 3.

[0029] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, eight placement cavities 31 are provided on the transmission disk 3. When the placement cavities 31, the first placement port 221 and the second placement port 222 are simplified into a line, the distance between each placement cavity 31 is 45°, and the angle between the first placement port 221 and the second placement port 222 is 157.5°. At this time, the first placement port 221 and the second placement port 222 are not symmetrically arranged, but the placement cavities 31 are evenly distributed on the transmission disk 3. This allows the second placement port 222 to be staggered from the other placement cavities 31 when the first placement port 221 corresponds to one of the placement cavities 31. This achieves structural locking of the placement cavities 31, so that during the rotation of the transmission disk 3, only one placement cavity 31 can correspond to the first placement port 221 or the second placement port 222, thereby further reducing the probability of medical accidents in this device.

[0030] Optionally, the first placement port 221 is provided with an openable and closable sealing door 4.

[0031] Exemplary, in embodiments of this utility model, such as Figure 2 and Figure 3 As shown, sealing doors 4 can be provided on both the first placement port 221 and the second placement port 222. By providing sealing doors 4, the embryo placed in the placement cavity 31 can be physically protected. The sealing doors 4 can be opened manually, or controlled by the system or electronically. The sealing doors 4 will only open when the placement cavity 31 to be operated is rotated to the corresponding position of the first placement port 221 or the second placement port 222. This design not only provides a certain degree of protection for the embryo but also further reduces the probability of medical accidents occurring with this device.

[0032] Optionally, the storage box 2 includes a base plate 21 and a top cover 22. The transmission disk 3 is rotatably disposed between the base plate 21 and the top cover 22. One end of the sealing door 4 is provided with a torsion spring 41. The sealing door 4 is rotatably disposed in the first placement port 221 via the torsion spring 41. A push plate 5 is provided on the side of the top cover 22 near the torsion spring 41. The bottom of the push plate 5 contacts the top of the sealing door 4. The push plate 5 is configured to move toward the sealing door 4.

[0033] Exemplary, in embodiments of this utility model, such as Figure 4 and Figure 5 As shown, in its natural state, the sealing door 4 is open due to the torsion spring 41. When it is necessary to close the sealing door 4, the push plate 5 is pushed horizontally, causing its bottom surface to press against the top surface of the sealing door 4, thus rotating the sealing door 4 until it closes. At this time, the torsion spring 41 retains its elastic potential energy. When the push plate 5 moves away from the sealing door 4, the sealing door 4 springs open under the elastic action of the torsion spring 41, thereby realizing the opening and closing of the sealing door 4. An electric push rod can be installed at the end of the push plate 5 away from the sealing door 4, thereby realizing electrical and automated control. By setting this structure, the ease of operation of this device is improved, and the probability of medical accidents caused by this device is further reduced.

[0034] Optionally, a limiting groove 51 is provided at the end of the push plate 5 away from the sealing door 4, and a pressure frame 6 is vertically arranged between the top cover 22 and the transmission disc 3. The pressure frame 6 is configured to move in the vertical direction. An inclined surface 61 is provided at the top of the pressure frame 6, and the inclined surface 61 contacts the groove wall of the limiting groove 51. A positioning groove 32 is provided on the transmission disc 3, and the bottom of the pressure frame 6 matches the positioning groove 32.

[0035] Exemplary, in embodiments of this utility model, such as Figure 4 and Figure 5As shown, the inclined surface 61 at the top of the pressure frame 6 faces the side wall of the limiting groove 32 near the sealing door 4. When the sealing door 4 is closed, the pressure frame 6 is located in the limiting groove 51. When the sealing door 4 needs to be opened, as the push plate 5 moves away from the sealing door 4, the limiting groove 51 presses against the inclined surface 61, causing the bottom surface of the push plate 5 to press the pressure frame 6 downward into the bottom positioning groove 32. This limits and fixes the top cover 22 and the transmission disc 3, thereby fixing the transmission disc 3. By setting this structure, the bottom of the pressure frame 6 can be inserted into the positioning groove 32 for fixation while the sealing door 4 is open, thereby restricting the rotation of the transmission disc 3. When the operator opens the sealing door 4 for operation, the transmission disc 3 is physically restricted and will not rotate, thus preventing damage to the embryo caused by the rotation of the transmission disc 3 when the operator operates on the embryo, thereby further reducing the probability of medical accidents with this device. In this embodiment, the limiting groove 51 can be designed according to the number of placement cavities 31. The number of limiting grooves 51 is twice that of placement cavities 31, and they are evenly spaced. When the operators on both sides of the isolation cabinet make a mistake, that is, when the sealing doors 4 on both sides are opened at the same time, the pressure frame 6 is prevented from being forcibly pressed down onto the transmission plate 3, causing damage to the pressure frame 6 or deformation of the transmission plate 3. Through this setting, the device can be protected to a certain extent in the event of operator error, thereby improving the service life of the device.

[0036] Optionally, a spring 7 is provided between the top cover 22 and the transmission disk 3. A through groove 62 matching the spring 7 is opened in the middle of the pressure frame 6. The spring 7 is set in the through groove 62, the top of the spring 7 is connected to the top of the through groove 62, and the bottom of the spring 7 is connected to the top of the transmission disk 3.

[0037] Exemplary, in embodiments of this utility model, such as Figure 4 and Figure 5 As shown, by setting spring 7, when the sealing door 4 is opened, the push plate 5 pushes the pressure frame 6 downward, and spring 7 accumulates elastic potential energy. When the sealing door 4 is closed, spring 7 releases elastic potential energy, causing the pressure frame 6 to rebound upward. By setting this structure, the pressure frame 6 can rebound after each opening and closing of the sealing door 4, making it convenient to continue working when opening and closing next time, thereby improving the ease of operation of this device.

[0038] Optionally, a distance sensor 8 is provided at the bottom of the pressure frame 6, and the distance sensor 8 is connected to the control system signal of the transmission disk 3.

[0039] Exemplary, in embodiments of this utility model, such as Figure 5As shown, by setting a distance sensor 8 at the bottom of the pressure frame 6, it is possible to detect whether the bottom of the pressure frame 6 is inserted into the positioning groove 32, thereby transmitting a signal to the control system of the transmission disk 4, so that the control system controls the transmission disk 3 to not rotate, thereby preventing the pressure frame 6 from being damaged due to the forced rotation of the transmission disk 3. By setting this structure, the service life of this device is further improved.

[0040] Optionally, the push plate 5 has a chamfer at one end near the sealing door 4.

[0041] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by providing a chamfer at one end of the push plate 5 near the sealing door 4, the bottom surface of the push plate 5 and the top surface of the sealing door 4 move more smoothly during friction, thereby making the opening and closing of the sealing door 4 more stable, reducing wear between the push plate 5 and the sealing door 4, and further improving the service life of the device.
