Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a multi-frozen storage tube thawing rack for a water bath. Background Technology
[0002] After cell cryovials are removed from the liquid nitrogen tank, they need to be thawed in a 37°C water bath. Existing methods for thawing cryovials typically involve placing the cryovials together with the cryovials in the water bath, or removing the cryovials from the cryovials, placing them on a thawing rack, and then placing them in the water bath. However, current thawing racks and cryovial racks are mostly flat, making them inconvenient to remove from the water bath. To improve the thawing efficiency of multiple cryovials, this application proposes a multi-cryovial thawing rack for a water bath. Utility Model Content
[0003] This invention proposes a defrosting rack for multiple cryogenic storage tubes in a water bath to improve the defrosting efficiency of multiple cryogenic storage tubes.
[0004] This utility model provides a multi-freezing tube thawing rack for a water bath, comprising: Frame; The hollow frame is arranged in a row on the lower end face of the frame and is connected to the row of through holes on the frame; the upper vertical section of the hollow frame is a trapezoidal structure and the lower vertical section of the hollow frame is a rectangular structure. The lifting rod is slidably mounted on both sides of the frame, with limit parts at both ends; The lifting ring is located at the upper end of the lifting rod.
[0005] The frame is made of plastic or metal.
[0006] Preferably, a circular hole is provided at the bottom of the cutout frame. The cutout frame is provided with cross-shaped through holes along its circumference.
[0007] Preferably, the frame body has annular protrusions at both ends, and the lifting rod slides within the annular protrusions. The annular protrusions have internal threads, and the lower end of the lifting rod has external threads. The lifting rod is threadedly connected to the annular protrusions through the external threads to lock the lifting rod in place after it is lifted.
[0008] Preferably, the device also includes a protective box, inside which the frame is placed. The protective box is transparent and has a label column.
[0009] Preferably, the lifting rod includes a sleeve and a telescopic rod. The sleeve is slidably connected to the frame, and the end of the telescopic rod is threadedly connected to the upper end of the sleeve, so that the telescopic rod is threadedly connected after sliding to its end inside the sleeve.
[0010] Compared with existing technologies, it has the following beneficial effects: This invention improves the thawing efficiency of cryovials by arranging multiple rows of hollow frames in the lower part of the frame, and by using the trapezoidal structure of the upper vertical section and the rectangular structure of the lower vertical section of the hollow frames to allow the cryovials placed inside to have a larger contact area with warm water in the water bath. At the same time, by installing lifting rods on both sides of the frame and setting lifting rings on the lifting rods, it is convenient for test personnel to take the thawing frame out of the water bath.

[0014] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings: Example 1: like Figures 1 to 3 As shown, this utility model provides a multi-crystal storage tube thawing rack for a water bath, comprising: Frame 1; The hollow frame 2 is arranged in a row on the lower end face of the frame 1 and is connected to the row of through holes on the frame 1. The upper vertical section of the hollow frame 2 is a trapezoidal structure, and the lower vertical section of the hollow frame 2 is a rectangular structure. The cryopreservation tube is clamped by the lower rectangular structure of the hollow frame 2. The upper vertical section of the hollow frame 2 is a trapezoidal structure to increase the contact area between the outer wall of the cryopreservation tube and the water in the water bath. Lifting rod 3 is slidably mounted on both sides of frame 1, with limiting parts at both ends to limit the upper and lower ends of lifting rod 3 to prevent lifting rod 3 from detaching from frame 1; Lifting ring 4 is located at the upper end of lifting rod 3.
[0015] See Figure 1 The frame 1 is made of plastic or metal.
[0016] See Figure 2 The bottom of the hollow frame 2 is provided with a round hole 21 so that the hot water in the bath can come into contact with the bottom of the cryopreservation tube through the round hole 21.
[0017] See Figure 2 The hollow frame 2 is provided with cross-shaped through holes 22 along the circumference so that the hot water in the water bath can come into contact with the outer wall of the cryopreservation tube through the cross-shaped through holes 22.
[0018] Example 2: As another embodiment of this utility model, such as Figure 2 As shown, the frame 1 has annular protrusions 11 at both ends, and the lifting rod 3 slides within the annular protrusions 11 to facilitate sliding and limiting the lifting rod 3.
[0019] The annular protrusion 11 is provided with an internal thread, and the lower end of the lifting rod 3 is provided with an external thread. The lifting rod 3 is threadedly connected to the annular protrusion 11 through the external thread to lock the lifting rod 3 after it is lifted, so that the test personnel can wear low temperature gloves and take the thawing rack out of the water bath through the lifting ring 4.
[0020] Furthermore, the lifting ring 4 can be used with a hook or clamp to remove or place the thawing rack from the water bath.
[0021] Example 3: As another embodiment of this utility model, such as Figure 4 and Figure 5 As shown, it also includes a protective box 5, with the frame 1 placed inside the protective box 5 to facilitate the sealing and preservation of the cryopreservation tubes; it can also be used as a cryopreservation box for freezing in liquid nitrogen.
[0022] The protective box 5 is transparent to facilitate observation of the cryopreservation tubes inside.
[0023] See Figure 5 The protective box 5 is equipped with a label column 51 to facilitate the labeling of cryopreservation tubes.
[0024] Example 4: In another embodiment of this utility model, the lifting rod 3 includes a sleeve and a telescopic rod (not shown). The sleeve is slidably connected to the frame 1, and the end of the telescopic rod is threadedly connected to the upper end of the sleeve, so that the telescopic rod is threadedly connected after sliding to its end inside the sleeve.
[0025] In this embodiment, the extension of the lifting rod 3 is further increased by sliding and threading the telescopic rod and the sleeve, so that it can be placed in water baths of different depths.
[0026] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
