The top of the base 1 is provided with a threaded groove 101 adapted to the thread of the connecting bolt 7, so that the connecting bolt 7 can be extended to the inside of the base 1 by using the threaded groove 101, thereby realizing the positioning and installation of the support plate 2. The support plate 2 is L-shaped, so that the support plate 2 can be kept in a vertical state while being easy to install.

[0027] Among them, the outer side of the support plate 2 is slidably connected with a movable sleeve 3, and a plurality of first limiting holes 201 are opened inside the support plate 2. The internal thread of the movable sleeve 3 is connected with a first fastening bolt 12 passing through the first limiting hole 201, so that the first fastening bolt 12 can pass through the support plate 2 using the first limiting hole 201 to achieve the effect of limiting the movement of the movable sleeve 3. The right side of the movable sleeve 3 is fixedly connected with a hook 13, so that the detail bag can be installed conveniently using the hook 13.

[0028] In this embodiment, the movable sleeve 3 is internally slidably connected with a long hole plate 4, and the movable sleeve 3 is L-shaped, so that the long hole plate 4 can slide in the movable sleeve 3 while keeping the movable sleeve 3 vertical. A plurality of second limiting holes 401 are provided inside the long hole plate 4, and the movable sleeve 3 is internally threadedly connected with a second fastening bolt 14 passing through the second limiting hole 401, so that the second fastening bolt 14 can pass through the long hole plate 4 using the second limiting hole 401, thereby limiting the movement of the long hole plate 4.

[0029] Among them, a fluid infusion hole 402 is opened inside the long hole plate 4, which is convenient for the fluid infusion syringe to pass through the long hole plate 4 via the fluid infusion hole 402. The top of the long hole plate 4 is fixedly connected with a fixing plate 5 located on the front and rear sides of the fluid infusion hole 402. Two clamping blocks 6 are movably connected on the opposite side of the two fixing plates 5. The clamping blocks 6 are V-shaped, and the two clamping blocks 6 are symmetrically arranged, which is convenient for the two clamping blocks 6 to be brought together to clamp and fix the fluid infusion syringe. A shifting component for adjusting the position of the clamping blocks 6 is provided on the opposite side of the two fixing plates 5.

[0030] Among them, the shifting assembly includes a shifting screw 15 fixedly connected to the inside of the fixing plate 5 which is threadedly connected and rotatably connected to the clamping block 6. Ear plates 16 are fixedly connected to the left and right sides of the clamping block 6. The opposite side of the two fixing plates 5 is fixedly connected to a guide rod 17 which is slidably connected to the ear plate 16, so that the clamping block 6 can move in the front and rear directions with the rotation of the shifting screw 15. The end of the shifting screw 15 away from the clamping block 6 is fixedly connected to a hand wheel 1501, so that the shifting screw 15 can be rotated conveniently using the provided hand wheel 1501.

A plurality of positioning grooves 102 are provided on the top of the base 1, and the positioning grooves 102 are evenly arranged in a circular shape, so that the positioning rod 10 can move downward under the action of the extrusion spring 11, so that when the positioning rod 10 is inserted into the positioning groove 102, it can limit the rotation of the support plate 2.

[0032] It should be noted that the base 1, support plate 2, movable sleeve 3, long hole plate 4, fixed plate 5 and clamping block 6 appearing in the text are all made of stainless steel materials, so that the infusion rack can meet the requirements of high temperature and high pressure sterilization.

[0033] The beneficial effects of the above embodiments are:

[0034] The adjustable cell rehydration stand can not only adjust the height of the rehydration stand as needed, but also adjust the lateral position of the rehydration hole 402 on the long hole plate 4 as needed, so as to improve the practical effect of the device; the position of the clamping block 6 can also be adjusted to make the rehydration stand meet the fixing requirements of rehydration syringes of different sizes, thereby facilitating the installation of rehydration syringes of different sizes, effectively reducing the use cost, and enhancing the practicality and applicability of the device;

[0035] During this process, the support plate 2 can also be rotated on the base 1 with the connecting bolt 7 as the axis to facilitate the adjustment of the orientation of the infusion stand, thereby further improving the practicality of the device; in addition, the infusion stand is composed of multiple different stainless steel structures and is easy to assemble and disassemble. Not only can the infusion stand be disassembled when not in use, making storage simple, but the infusion stand can also be sterilized at high temperature and high pressure, which can reduce the probability of contamination to a greater extent compared to acrylic plates on the market.

[0036] The working principle of the above embodiment is:

[0037] When the adjustable cell infusion rack is used, the support plate 2 needs to be placed on the base 1 first, and the connecting bolt 7 passes through the support plate 2 and is connected to the threaded groove 101 on the base 1, so that the support plate 2 is installed on the base 1; thereby, the support plate 2 can be conveniently rotated on the base 1 with the connecting bolt 7 as the axis to achieve the effect of adjusting the direction of the infusion rack; and the positioning rod 10 provided can move downward under the action of the extrusion spring 11, so as to play the role of limiting the rotation of the support plate 2 when the positioning rod 10 is inserted into the positioning groove 102;

[0038] Then, the movable sleeve 3 can be sleeved on the outside of the support plate 2, and the position of the movable sleeve 3 on the support plate 2 can be adjusted as needed to facilitate the height adjustment of the fluid infusion rack. After the adjustment, the first fastening bolt 12 can pass through the support plate 2 using the first limiting hole 201 to limit the movement of the movable sleeve 3. Then, the long hole plate 4 can be inserted into the movable sleeve 3, and the position of the long hole plate 4 in the movable sleeve 3 can be adjusted as needed to facilitate the adjustment of the lateral position of the fluid infusion hole 402 on the long hole plate 4. After the adjustment is completed, the second fastening bolt 14 can pass through the long hole plate 4 using the second limiting hole 401 to limit the movement of the long hole plate 4.
