Apparently, the described implementation manners are only part of the implementation manners of the utility model, instead of all the implementation manners. Based on the implementation manners in the utility model, all other implementation manners obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0042] As Figures 1-4 shown, the novel cell culture bag support of the utility model comprises an elastic tray 1, a frame 2 and a support leg 3.

[0043] Among them, the elastic tray 1 is in a rectangular shape, and one telescopic rod 21 is arranged on each of the four side ends of the elastic tray 1, and the telescopic rod 21 is used to expand the length or width of the elastic tray 1; the four telescopic rods 21 are horizontally arranged and connected at the head and tail to form the frame 2; one support leg 3 is arranged at each of the four corners of the frame 2.

[0044] The support leg 3 is vertically arranged and is used to support the frame 2, so that the elastic tray 1 is suspended, and the top of the suspended elastic tray 1 is used to place a bacterial culture bag. When the size of the bacterial culture bag to be placed is large, the telescopic rod 21 is stretched to expand the width of the elastic tray 1, that is, the length and width of the elastic tray 1 are increased by stretching the four telescopic rods 21, so that the placement requirement of the large-size bacterial culture bag is met.

[0045] In addition, the support leg 3 is any one of the folding support rods in the prior art, such as the foldable support rod disclosed in CN206947495U. As Figure 1As shown, the upper half of the support leg 3 can be folded and placed above the frame 2, and the lower half can be folded and placed below the frame 2, so as to facilitate the storage of the device.

[0046] In the above structure, the longer the telescopic rod 21 is stretched, the larger the length and width of the elastic tray 1, and vice versa. According to the actual size of the bacterial culture bag, the width of the elastic tray 1 is adjusted to an appropriate size.

[0047] As shown in the drawings, Figure 1 As shown, a culture bag placing groove 201 is formed between the elastic tray 1 and the frame 2. Specifically, the edge of the elastic tray 1 is fixedly connected to the bottom surface of the frame 2. After the two are fixedly connected, the frame 2 forms the outer edge of the elastic tray 1, which restricts the bacterial culture bag from sliding off the elastic tray 1.

[0048] As shown in the drawings, Figure 3 As shown, the telescopic rod 21 includes left and right screw rods 211 and outer sleeves 212. The two ends of the left and right screw rods 211 are respectively screwed with an outer sleeve 212, and a knob part 21101 is arranged on the middle part of the left and right screw rods 211. The end of the outer sleeve 212 away from the left and right screw rods 211 is fixedly connected with the support leg 3, and the side of the outer sleeve 212 is fixedly connected with the side end of the elastic tray 1. Specifically, when the support leg 3 is a folding support rod, it includes upper, middle and lower support rods, and one end of the outer sleeve 212 is fixedly connected with the middle support rod.

[0049] The knob part 21101 is a multi-prism structure. When the length of the telescopic rod 21 needs to be adjusted, the left and right screw rods 211 are rotated through the knob part 21101. During the process, the two outer sleeves 212 on the left and right screw rods 211 are moved closer to or farther away from each other to achieve length adjustment. The knob part 21101 is a multi-prism structure. During the adjustment process, first adjust the two telescopic rods 21 that are parallel to each other, and then adjust the other two telescopic rods 21 to facilitate the adjustment operation.

[0050] The above-mentioned elastic tray 1 is provided as an elastic rubber plate or an elastic net. When the elastic tray 1 is an elastic rubber plate, as shown in the drawings, Figure 1 As shown, a plurality of air holes 101 are arranged vertically on the elastic tray 1, which are used for air permeation at the bottom of the bacterial culture bag to promote gas exchange and ensure the healthy growth of cells.

[0051] When the elastic tray 1 is an elastic net, as shown in the drawings, Figure 3 As shown, the elastic tray 1 is woven by a plurality of elastic rope bodies, and the mesh holes are prismatic or other geometric shapes, and the mesh holes have the same effect as the air holes 101.

[0052] In actual application, as shown in the drawings, Figure 1As shown, several elastic ropes 4 are arranged above the elastic tray 1, which are used to fix the culture bag placed in the culture bag placing groove 201, prevent the culture bag from shaking or moving, and effectively improve the cell quantity and activity.

[0053] Wherein, the two ends of the elastic rope 4 are detachably arranged on the frame 2, and specifically, the two ends of the elastic rope 4 are provided with hook parts 401, when the bacterial culture bag is placed in the culture bag placing groove 201, the hook parts 401 are hung on the side of the telescopic rod 21, so that the elastic rope 4 is pressed on the top of the bacterial culture bag, and the fixing of the bacterial culture bag is realized.

[0054] When the bacterial culture bag is fixed, the elastic ropes 4 can be arranged in parallel or cross. When the bacterial culture bag needs to be taken out, the hook parts 401 are detached from the telescopic rod 21. In order to facilitate the cross installation of the elastic rope 4, a plurality of ring grooves are arranged on the outer pipe wall of the outer sleeve 212, the hook parts 401 are hung in the ring grooves, and the displacement of the hook parts 401 is limited by the ring grooves, wherein the ring grooves and the cross elastic rope 4 are not drawn in the drawing.

[0055] In addition, the upper end of the supporting leg 3 is provided with a plug part 301, and the lower end is provided with a slot part 302. Wherein, the inner diameter of the plug part 301 is greater than or equal to the outer diameter of the slot part 302. Figure 4 As shown, through the structure, the stacking use of the two above-mentioned cell culture bag supports can be realized, and when stacking, the slot part 302 of the upper support is inserted into the plug part 301 of the lower support, so as to form effective support and improve the stability of the upper support.

[0056] In addition, the supporting leg 3 in the above-mentioned support can also be a common supporting rod structure, that is, the supporting leg 3 does not have folding ability, and one of the structures is selected according to actual needs.

[0057] The use method of the novel cell culture bag support of the present application is as follows:

[0058] Before using the support, the support is sterilized, and after sterilization, it is placed in a clean bench; according to the size of the culture bag, the telescopic rod 21 is stretched, and the elastic tray 1 is adjusted to the appropriate size; the cell culture bag is placed on the elastic tray 1, and the elastic rope 4 is installed on the top of the cell culture bag, and then the related experimental operation is carried out.

[0059] The above only describes the preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
