Description

Technical Field

[0001] This utility model relates to the field of immune cell reinfusion technology, and in particular to a cell culture bag tray. Background Technology

[0002] In the fields of biological experiments and cell culture, cell culture bags are commonly used cell culture carriers. Their stable placement and safe operation directly affect the success rate of cell culture. When removing immune cells from the storage container, the culture bag needs to be lifted very high by hand. Holding the arm straight up for a long time can cause soreness and make it difficult to maintain the position for a certain period of time. At the same time, the ordinary placement method cannot adapt to the curved outer wall of the culture bag, which can easily cause the culture bag to shake due to mismatch of the placement surface, or even tip over or slip, which may cause damage to the culture bag and leakage of culture medium. Secondly, the height requirements of the culture bag vary in different scenarios, and the traditional method of manually lifting the tray cannot stabilize the position of the tray and makes it difficult to adjust the height accurately.

[0003] Therefore, we propose a cell culture bag tray. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cell culture bag tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cell culture bag tray includes a tray and an auxiliary mechanism. A support column is fixedly provided on one side of the tray, and a groove is formed on the inner side of the support column. The auxiliary mechanism is located inside the groove. The auxiliary mechanism includes a limiting groove, a turbine, and a worm gear. Limiting grooves are formed at both ends of the inner side of the groove. A lead screw is movably provided above the limiting groove. A turbine is fixedly provided above the lead screw. A worm gear is engaged on one side above the turbine.

[0007] As a further improvement of this utility model: a support base is fixedly provided at the bottom end of the support column, and a rubber buffer pad is fixedly provided at the bottom end of the support base.

[0008] As a further improvement of this utility model: the upper surface of the tray is provided with an arc-shaped concave surface, which is adapted to the outer wall of the cell culture bag, and limit blocks are fixedly provided at both ends of the upper surface of the tray.

[0009] As a further embodiment of this utility model: a conveying hole is provided on one side of the limiting block, an adjusting strap is fixedly provided on the upper side of the limiting block, and a burr surface is fixedly provided on the upper side of the other limiting block, and the adjusting strap is adhered and fixed to the burr surface.

[0010] As a further embodiment of this utility model: a sliding block is movably arranged above the lead screw, one end of the sliding block is integrally formed with the support plate, and a handwheel is provided through and extended from one end of the worm gear.

[0011] As a further improvement of this utility model: a hand-held part is fixedly provided at the end of the support column away from the slide groove, and an anti-slip sleeve is fitted on the upper part of the hand-held part.

[0012] Compared with the prior art, the present invention provides a cell culture bag tray, which has the following beneficial effects:

[0013] 1. This utility model utilizes the arc-shaped concave surface on the upper surface of the tray to precisely fit the outer wall of the cell culture bag, providing a close-fitting support for the culture bag from the bottom. This prevents the culture bag from shaking due to mismatched placement surfaces. Simultaneously, the limiting blocks at both ends of the upper surface of the tray can laterally limit the culture bag from both sides, further restricting its horizontal displacement. Furthermore, the adjusting strap above one limiting block and the burr surface above the other limiting block can form an adhesive fixing structure. Operators can adjust the tightness of the strap according to the actual size of the culture bag, achieving flexible fixing of culture bags of different sizes. This avoids the culture bag slipping due to excessive looseness or being squeezed and damaged due to excessive tightness, thus improving the safety of the device.

[0014] 2. In this utility model, a sliding groove is provided on the inner side of the support column on one side of the pallet. The lead screw inside the sliding groove cooperates with the sliding block of the pallet integral structure, and the worm gear above the lead screw meshes with the worm. The operator only needs to turn the handwheel at one end of the worm gear to drive the lead screw to rotate through the worm gear, thereby driving the sliding block to move up and down along the sliding groove, so as to achieve precise adjustment of the pallet height. No additional tools are required, the operation is simple and labor-saving, the pallet height can be flexibly adjusted, and the comfort of use is improved.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example: A cell culture bag tray 1, such as Figures 1-3 As shown, the device includes a support plate 1 and an auxiliary mechanism 2. A support column 3 is fixedly installed on one side of the support plate 1. A slide groove 4 is formed on the inner side of the support column 3. The auxiliary mechanism 2 is located inside the slide groove 4. The auxiliary mechanism 2 includes a limiting groove 201, a turbine 202, and a worm gear 203. Limiting grooves 201 are formed at both ends of the slide groove 4. A lead screw 204 is movably installed above the limiting groove 201. A turbine 202 is fixedly installed above the lead screw 204. A worm gear 203 is meshed on one side above the turbine 202. The device is supported by a support column 3 on one side of the support plate 1. A groove 4 is provided on the inner side of the column 3. The lead screw 204 inside the groove 4 cooperates with the sliding block 12, which is an integral structure of the pallet 1. The worm gear 202 above the lead screw 204 is meshed with the worm 203. The operator only needs to turn the handwheel 13 at one end of the worm 203 to drive the lead screw 204 to rotate through the worm gear 202, thereby driving the sliding block 12 to move up and down along the groove 4, so as to achieve precise adjustment of the height of the pallet 1. No additional tools are needed, the operation is simple and labor-saving, and the height of the pallet 1 can be flexibly adjusted to improve the comfort of use.

[0023] like Figures 1-3 As shown, a support base 5 is fixedly installed at the bottom end of the support column 3, and a rubber buffer pad 6 is fixedly installed at the bottom end of the support base 5. The rubber buffer pad 6 can effectively isolate external vibrations and provide a stable support environment for cell culture.

[0024] like Figures 1-3As shown, the upper surface of the tray 1 has an arc-shaped concave surface 7, which is adapted to the outer wall of the cell culture bag. Limiting blocks 8 are fixedly installed at both ends of the upper surface of the tray 1. By precisely adapting the arc-shaped concave surface 7 on the upper surface of the tray 1 to the outer wall of the cell culture bag, the culture bag can be supported from the bottom, preventing the culture bag from shaking due to mismatch of the placement surface.

[0025] like Figures 1-3 As shown, a conveying hole 9 is provided on one side of the limiting block 8, and an adjusting strap 10 is fixedly installed above the limiting block 8. A burr surface 11 is fixedly installed on one side of the upper part of the other limiting block 8. The adjusting strap 10 and the burr surface 11 are glued and fixed. The limiting blocks 8 at both ends of the upper surface of the tray 1 can laterally limit the culture bag from both sides, further restricting its horizontal displacement. The adjusting strap 10 above one limiting block 8 and the burr surface 11 above the other limiting block 8 can form a glued fixing structure. The operator can adjust the tightness of the strap 10 according to the actual size of the culture bag to achieve flexible fixing of culture bags of different specifications, avoiding the culture bag from slipping due to loose fixing or the culture bag from being squeezed and damaged due to tight fixing, thus improving the safety of the device.

[0026] like Figures 1-3 As shown, a sliding block 12 is movably arranged above the lead screw 204. One end of the sliding block 12 is integrally formed with the support plate 1. A handwheel 13 is provided through and extended at one end of the worm gear 203. By rotating the handwheel 13, the lead screw 204 is driven to rotate, so that the sliding block 12 above can move stably up and down.

[0027] like Figures 1-3 As shown, a handhold 14 is fixedly provided at the end of the support column 3 away from the slide groove 4. An anti-slip sleeve 15 is fitted on the top of the handhold 14. The handhold 14 at the end of the support column 3 away from the slide groove 4 provides a convenient grip point for the operator, and the anti-slip sleeve 15 fitted on the top of the handhold 14 can increase the friction between the hand and the handhold 14.

[0028] Working principle: When using the cell culture bag tray 1, the cell culture bag is placed in the arc-shaped concave surface 7 on the upper surface of the tray 1. The arc-shaped concave surface 7 precisely fits the outer wall of the culture bag, forming a close-fitting support for the culture bag from the bottom, preventing the culture bag from shaking due to mismatch in placement. At the same time, the limiting blocks 8 at both ends of the upper surface of the tray 1 laterally limit the culture bag from both sides, restricting its horizontal displacement. Then, according to the actual size of the culture bag, the operator pulls the adjusting strap 10 above one of the limiting blocks 8, so that it passes over the top of the culture bag and is attached and fixed to the burr surface 11 above the other limiting block 8. By adjusting the tightness of the strap 10, flexible fixation of culture bags of different sizes can be achieved, preventing the culture bag from slipping or being damaged due to excessive compression. If it is necessary to transfer culture medium into the culture bag or extract samples, it can be done through the delivery hole 9 on one side of the limiting block 8. The operation requires no disassembly of the fixed structure. When adjusting the height, the operator uses the auxiliary mechanism 2 inside the inner groove 4 of the support column 3 to rotate the handwheel 13 extending from one end of the worm gear 203. The worm gear 203 drives the worm 202 meshing with it to rotate. The worm 202 is fixed above the lead screw 204, which in turn drives the lead screw 204 to rotate synchronously. The lead screw 204 is movably connected to the sliding block 12, and one end of the sliding block 12 is an integral structure with the tray 1. When the lead screw 204 rotates, it drives the sliding block 12 to move up and down along the groove 4, thereby driving the tray 1 to achieve height adjustment. The limiting grooves 201 at both ends inside the groove 4 can limit the movement range of the sliding block 12 to ensure the stability and safety of the height adjustment process. When moving and transferring the tray 1 and the culture bag, the operator holds the hand-held part 14 at the end of the support column 3 away from the groove 4 to transfer it.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
