Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a water bath floating plate. Background Art

[0002] During the clinical use of cell products, it is necessary to resuscitate the sterile cryopreservation bottles of frozen cells within a specified time. Most resuscitation operations are performed using a water bath. It is common to use a floating plate to fix the sterile cryopreservation bottle and then float it on the water bath liquid surface.

[0003] Existing float plates are made of foam or hard plastic materials. There are some defects in the float plates of this structure. First, the hard plastic float plate has a smooth inner diameter. When the sterile cryopreservation bottle is light in weight, it cannot be effectively fixed, and the sterile cryopreservation bottle is easy to float during use; second, the thickness of the foam float plate is usually more than 5 mm, and the float plate wraps a large part of the sterile cryopreservation bottle wall, so the sterile cryopreservation bottle cannot fully contact the water bath environment, the conduction efficiency is reduced, and there is a possibility of cell recovery timeout, which affects the activity of the cells after recovery; third, the float plate is a flat plate structure. During operation, the liquid can easily overflow the float plate, causing the sterile cryopreservation bottle seal to enter the water bath liquid, which can easily contaminate the product and affect its use. Utility Model Content

[0004] The utility model aims at solving the problems and shortcomings of the prior art and provides a water bath float for reviving cells in sterile cryopreservation bottles.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model provides a sterile cryopreservation bottle cell recovery water bath float, comprising a float plate, characterized in that the float plate is a silicone base plate made of silicone material, and a cryopreservation bottle fixing hole for passing the sterile cryopreservation bottle is opened on the silicone base plate;

[0007] It also includes an upper anti-overflow plate, on which a through hole is provided that corresponds one-to-one with the cryopreservation bottle fixing hole. The inner diameter of the through hole is larger than the inner diameter of the cryopreservation bottle fixing hole, and the lower end of the through hole is fixedly connected to the outer area of ​​the cryopreservation bottle fixing hole through a bellows.

[0008] The utility model adds an upper anti-overflow plate, which facilitates controlling the stretching degree of the bellows through the distance between the upper anti-overflow plate and the floating plate, thereby preventing the water bath liquid from entering the sealing part of the sterile cryopreservation bottle.

[0009] After the upper anti-overflow plate is fixed, the bellows are provided to facilitate the adaptive adjustment of the distance between the floating plate and the upper overflow plate according to the liquid level of the water bath.

[0010] The inner diameter of the through hole is larger than the inner diameter of the fixing hole of the freezing bottle, which facilitates the operation of taking out the sterile freezing bottle after the bellows is compressed.

[0011] Further preferably, the outer edge of the upper anti-overflow plate is connected to a hook for hanging on the side wall of the water bath.

[0012] Further preferably, the upper anti-overflow plate is a plastic plate.

[0013] Further preferably, a limit rod is threadedly connected to the upper anti-overflow plate.

[0014] It is convenient to limit the minimum value of the relative position distance between the upper anti-overflow plate and the silicone base plate by adjusting the upper and lower positions of the limit rod.

[0015] Further preferably, the outer edge of the upper anti-overflow plate is provided with an annular protrusion extending upward.

[0016] Further preferably, a protrusion for detachably connecting to a counterweight ring is provided on the outer edge of the silicone substrate, and a snap-in hole for snapping the protrusion is provided on the counterweight ring.

[0017] By adding a counterweight ring, the deadweight is increased, and the silicone substrate is pulled downward, making it easier to immerse the sterile cryopreservation bottle in the water bath and speeding up the water bath processing time.

[0018] Further preferably, the thickness of the silicone substrate is 1-3 mm.

[0019] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0020] The positive progressive effect of the utility model is that the utility model fixes the sterile cryopreservation bottle through the silica gel substrate and avoids the sealing portion of the sterile cryopreservation bottle from being immersed in the water bath liquid.

[0026] like Figure 1 As shown in specific embodiment 1, a sterile cryopreservation bottle cell recovery water bath float comprises a float plate, which is a silicone substrate 1 made of silicone material, and the silicone substrate 1 is provided with a cryopreservation bottle fixing hole 11 for passing the sterile cryopreservation bottle; and further comprises an upper anti-overflow plate 2, which is provided with a through hole 21 arranged one-to-one with the cryopreservation bottle fixing hole 11, the inner diameter of the through hole 21 being larger than the inner diameter of the cryopreservation bottle fixing hole 11, and the lower end of the through hole 21 is fixedly connected to the peripheral area of ​​the cryopreservation bottle fixing hole 11 through a bellows 3. By adding the upper anti-overflow plate 2, the utility model facilitates the control of the stretching degree of the bellows 3 by the spacing between the upper anti-overflow plate 2 and the float plate, thereby preventing the sterile cryopreservation bottle seal from entering the water bath liquid. When the upper anti-overflow plate 2 is fixed, the bellows 3 are provided to facilitate the adaptive adjustment of the spacing between the float plate and the upper overflow plate according to the liquid level of the water bath. The inner diameter of the through hole 21 is larger than the inner diameter of the freezing bottle fixing hole 11 , so that the operation of taking out the sterile freezing bottle is facilitated after the bellows 3 is compressed.

[0027] The outer edge of the upper anti-overflow plate 2 is connected to a hook 4 for hanging on the side wall of the water bath.

[0028] The thickness of the silicone substrate 1 is 1-3 mm.
