Description

Technical Field

[0002] Glucagon is a protein hormone secreted by pancreatic islet cells, which works together with insulin to regulate blood sugar levels. The storage of islet cells for islet transplantation often requires a fine storage device to perform storage operations on the islet cells for islet transplantation.

The pancreatic islet cell storage device for islet transplantation, by setting a first spring and a second spring, when the device as a whole is vibrated, the liquid nitrogen box completely outputs the kinetic energy generated by the vibration to the two first springs and the two first tooth plates through the connecting plate, and the first spring first buffers most of the kinetic energy, and the rest is transmitted to the second tooth plate by the first tooth plate driving the gear, and then transmitted to the second spring by the second tooth plate, and the rigid collision generated by the vibration will be completely converted into a flexible collision that compresses the two springs, which greatly reduces the vibration effect on the test tube, greatly improves the safety performance, and achieves the effect of strong earthquake resistance.

[0004] However, although the cell storage device can store islet cells for islet transplantation, the observation effect of the storage temperature of islet cells for islet transplantation is not high, so that when the islet cells are stored in different environments, the temperature inside the storage device cannot be observed, which reduces the storage stability of the islet cells. When the observation window is not in use, the light protection effect for the cells stored inside the storage box is not high, resulting in the problem of reduced storage activity of the islet cells.

[0005] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a pancreatic islet cell storage device for islet transplantation is proposed. Utility Model Content

[0025] Embodiment 1

[0026] like Figure 1-Figure 3As shown, a pancreatic islet cell storage device for islet transplantation includes a device body 1 and a protection mechanism arranged on the outer wall of the device body 1, wherein the protection mechanism includes a sliding assembly;

[0027] The sliding assembly includes a threaded rod 23 and a baffle 24. The outer wall of the device body 1 is rotatably connected to the connecting cover 11 through a hinge. A pancreatic islet cell storage test tube 12 is placed inside the device body 1. A temperature measuring meter 13 is arranged inside the device body 1. The outer wall of the device body 1 is provided with an observation window 2 located on one side of the temperature measuring meter 13. The outer wall of the device body 1 is fixedly connected to a limit rod 22. A knob 21 is arranged on the outer wall of the device body 1. One end of the knob 21 is fixedly connected to a threaded rod 23 rotatably connected to the outer wall of the device body 1. The outer wall of the threaded rod 23 is threadedly connected to a baffle 24 slidably connected to the outer wall of the limit rod 22.

[0028] Furthermore, two groups of limit rods 22 are provided, and the position distribution of the two groups of limit rods 22 is symmetrical about the central axis of the baffle 24, which is beneficial to improve the sliding stability of the baffle 24 by symmetrically distributing the position distribution of the two groups of limit rods 22 about the central axis of the baffle 24.

[0029] Furthermore, two groups of threaded rods 23 are provided, and the rotation directions of the two groups of threaded rods 23 are opposite. Two groups of baffles 24 are provided, and the position distribution of the two groups of baffles 24 is symmetrical about the central axis of the observation window 2. The baffles 24 form a sliding structure through the threaded rods 23 and the limiting rods 22, which is conducive to the rotation of the threaded rods 23 to drive the baffles 24 to slide along the outer wall of the limiting rod 22, thereby realizing the control operation of improving the observation effect of the storage temperature of the islet cells when the islet transplanted islet cells are stored through the storage device.

[0030] Furthermore, the width of the observation window 2 is greater than the width of the temperature measuring meter 13 , and the observation window 2 is transparent, which is conducive to setting the width of the observation window 2 greater than the width of the temperature measuring meter 13 , thereby realizing the control operation of observing the temperature of the temperature measuring meter 13 .

[0031] Furthermore, the width of the baffle 24 is greater than the width of the observation window 2, which is beneficial for preventing sunlight from directly shining on the insulin cells through the observation window 2 when there is no need to observe the storage temperature of the islet cells.

[0032] Embodiment 2

[0033] like Figure 1 , Figure 2 and Figure 4As shown, the utility model proposes a pancreatic islet cell storage device for islet transplantation. Compared with the first embodiment, as another embodiment of the utility model, the outer wall of the device body 1 is rotatably connected with a rotating card rod 3, the outer wall of the rotating card rod 3 is fixedly connected with a spring 31 fixedly connected with the outer wall of the device body 1, the outer wall of the rotating card rod 3 is fixedly connected with a telescopic rod 32 telescopically connected with the outer wall of the device body 1, and the outer wall of the connecting cover 11 is fixedly connected with a connecting card rod 33 engaged with the outer wall of the rotating card rod 3. By setting the connecting card rod 33, it is beneficial to store the islets through the storage device. When storing transplanted islet cells, in order to improve the storage stability of the islet cells and prevent them from tipping over, the rotating card rod 3 can be squeezed by connecting the connecting card rod 33 to make the rotating card rod 3 rotate. When the connecting card rod 33 moves into the card slot, the rotating card rod 3 is driven by the telescopic rod 32 and the spring 31 to rotate to its original position, so that the rotating card rod 3 can engage and fix the connecting card rod 33, thereby achieving control operation to improve the storage stability of the islet cells when storing transplanted islet cells through the storage device.

[0034] Furthermore, a card slot is provided at the connection portion between the outer wall of the rotating card rod 3 and the connecting card rod 33. The outer wall contour of the connecting card rod 33 is in an "L" shape. The outer wall contour of the rotating card rod 3 is in an "L" shape, and the connection portion between the connecting card rod 33 and the rotating card rod 3 is in an arc shape. The connecting cover 11 forms a card-fitting structure with the device body 1 through the rotating card rod 3 and the connecting card rod 33, which is beneficial to achieving control operations to improve the storage stability of pancreatic cells through the opening of the card slot.

[0035] Furthermore, two groups of connecting rods 33 are provided, and the position distribution of the two groups of connecting rods 33 is symmetrical about the central axis of the connecting cover 11, which is beneficial to improve the control operation of the clamping and fixing stability of the connecting cover 11 by setting the position distribution of the two groups of connecting rods 33 symmetrically about the central axis of the connecting cover 11.

[0036] Working principle: When using this islet cell storage device for islet transplantation, first, when islet cells for islet transplantation are stored through the storage device, in order to improve the observation effect of the storage temperature of the islet cells, the knob 21 can be turned to drive the baffle 24 to slide along the outer wall of the limiting rod 22 through the rotation of the threaded rod 23, so that the baffle 24 moves to both sides of the observation window 2, which plays a role in observing the storage temperature of the islet cells, thereby realizing the control operation of improving the observation effect of the storage temperature of the islet cells when the islet cells for islet transplantation are stored through the storage device.

[0037] Secondly, when it is not necessary to observe the storage temperature of the islet cells, in order to prevent the direct sunlight from the observation window 2 to the insulin cells, the knob 21 can be turned to drive the baffle 24 to slide along the outer wall of the limiting rod 22 through the rotation of the threaded rod 23, so that the baffle 24 blocks the observation window 2 to prevent the direct sunlight from the observation window 2 to the insulin cells, thereby achieving improved control of the islet cell storage effect when storing the islet transplanted islet cells through the storage device.

[0038] Finally, when the islet transplanted islet cells are stored through the storage device, in order to improve the storage stability of the islet cells and prevent them from tipping over, the rotating card rod 3 can be squeezed by connecting the connecting card rod 33 to make the rotating card rod 3 rotate. When the connecting card rod 33 moves into the card slot, the rotating card rod 3 is driven by the telescopic rod 32 and the spring 31 to rotate to its original position, so that the rotating card rod 3 can engage and fix the connecting card rod 33, thereby achieving the control operation of improving the storage stability of the islet cells when the islet transplanted islet cells are stored through the storage device.
