Description

Technical Field

[0001] The utility model relates to the technical field of identification devices, in particular to an external identification device for a biological sample freezing tube. Background Art

[0002] Cryogenic tubes are a product used to preserve various biological samples such as fungi, genetic information, metabolites, etc. at low temperatures, and play a major role in the biological and medical fields.

[0003] The method of sticking identification labels on the surface of the cryotube often leads to problems, such as the writing being partially or completely damaged and unrecognizable due to moisture or chemicals such as alcohol, or the label being debonded and lost, which results in the inability to correctly identify the sample. Therefore, most people now use built-in identification devices to identify the samples.

[0004] A built-in identification device for a medical biological sample cryopreservation tube is proposed in the Chinese patent publication number: CN220745914U. In this patent, an identification plate is installed on an assembly plate, and the assembly plate is fixed inside a placement slot by a spring so that it is located between an outer cover and a sealing cover, thereby preventing the identification plate from being stained with liquid and preventing the label paper from being debonded and lost.

[0005] However, the device fixes the identification plate by a spring. When the biological samples in the cryotube are frequently replaced, the staff needs to frequently change the information on the identification plate. In this process, the spring is frequently stretched and compressed, which makes the spring prone to metal fatigue, thereby affecting the service life of the spring. The staff needs to replace it frequently, which is too troublesome and easily increases cost expenditure. Utility Model Content

[0027] like Figures 1 to 6 As shown, Embodiment 1 of the utility model is a biological sample cryopreservation tube external identification device, comprising a sleeve 1, and an external identification member 2 is provided on the surface of the sleeve 1;

[0028] The external identification part 2 includes a fixing ring 21 fixedly mounted on the outer surface of the sleeve 1, a placement groove 22 is provided on the surface of the fixing ring 21, and an annular groove 23 with one end connected to the placement groove 22 is provided inside the fixing ring 21, an annular plate 24 is provided inside the annular groove 23, a convex block 27 is fixedly mounted on the front of the annular plate 24 for driving the annular plate 24 to move, an opening is provided on the front of the annular plate 24, and an observation window 28 for observing the label is fixedly mounted on the inner wall of the opening, an iron sheet 25 is fixedly mounted on one end of the annular plate 24, and a magnet 26 is fixedly mounted on the inner wall of the placement groove 22 on one side away from the annular groove 23;

[0029] The external identification component 2 also includes slide grooves provided on the inner bottom wall and the inner top wall of the annular groove 23 and the placement groove 22. The upper and lower sides of the annular plate 24 are fixedly mounted with semicircular slide plates 29 slidably arranged in the corresponding slide grooves.

[0030] When it is necessary to perform frozen storage of biological samples, the biological samples are placed in cryogenic tubes, and then the cryogenic tubes are placed inside the sleeve 1, thereby completing the storage of the cryogenic tubes. After the information of the biological samples is input into the computer, the printed labels are taken out and pasted into the placement slot 22. The annular plate 24 is moved by the protrusion 27 so that the iron sheet 25 on one side of the annular plate 24 can contact the magnet 26, so that the iron sheet 25 is adsorbed by the magnet 26, thereby completing the closure of the placement slot 22; when it is necessary to replace the label, it is only necessary to move the annular plate 24 by the protrusion 27 to complete the replacement of the label, and the annular plate 24 is fixed by adsorption between the magnet 26 and the iron sheet 25. Since the service life of the magnet 26 is long, the staff does not need to frequently replace the magnet 26, which saves the staff's workload and reduces unnecessary cost expenditure.

[0031] The cooperation between the slide plate 29 and the slide groove enables the annular plate 24 to slide stably inside the annular groove 23 .

[0032] Embodiment 2 of the present utility model is an external identification device for a biological sample freezing tube. Based on embodiment 1, an extraction groove 8 is opened on the inner wall of the placement groove 22.

[0033] When the label is pasted inside the placement slot 22 , one end of the label is located on the surface of the extraction slot 8 , so that this end of the label is in a suspended state, which is convenient for the staff to take out the label from the placement slot 22 .

[0034] Embodiment 3 of the utility model is an external identification device for a biological sample freezing tube. On the basis of embodiment 1 or 2, fixing parts 3 for fixing the freezing tube are arranged on the upper and lower sides of the external identification part 2 on the inner wall of the sleeve 1; the fixing part 3 includes a support ring 31 fixedly installed on the inner wall of the sleeve 1, a rubber pad 32 is fixedly installed on the inner wall of the support ring 31, and a plurality of flow holes 33 are opened on the surface of the support ring 31.

The rubber pad 32 arranged inside the support ring 31 facilitates the support and protection of the surface of the cryotube. At the same time, the elastic property of the rubber pad 32 enables the fixing part 3 to support cryotubes of different diameters. At the same time, a plurality of flow holes 33 are arranged in the support ring 31 to facilitate the flow of cold air between two adjacent support rings 31.

[0036] Embodiment 4 of the utility model is an external identification device for a biological sample freezing tube.
