Description

Technical Field

[0001] The utility model belongs to the technical field of reagent preservation, and specifically relates to a refrigeration device for reagents supporting a blood cell analyzer. Background Art

[0002] The reagents used in blood cell analyzers usually need to be stored in a refrigerator to ensure their stability and effectiveness. According to the requirements of the reagents, they usually need to be stored in a refrigerator at a temperature range of 2°C to 8°C. Since blood cell analyzers need to continuously test and analyze a variety of reagents, the reagents need to maintain a certain stability during storage to facilitate the stability of blood cells.

[0003] In the prior art, most of the refrigerated storage devices for reagents use incubators or dry ice for cooling and preservation. Due to the high density of cold air flow, cold air is more easily attracted by gravity to settle downward than the surrounding warm air. When most reagent tubes are refrigerated, the temperature at the bottom is much lower than the temperature at the top. This will cause inconsistent activity of blood cells in the reagents, resulting in problems such as unstable data or large data deviation in the subsequent analyzer. Utility Model Content

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-Figure 5 As shown, a refrigeration device for reagents of a blood cell analyzer includes a storage box 1, a sealing cover 2 is movably connected to the top of the storage box 1, the inner wall of the storage box 1 is arranged in a stepped shape, a placement plate 3 is arranged at the position of the step in the inner cavity of the storage box 1, a plurality of test tube holes 4 are opened on the top surface of the placement plate 3, and rubber rings 20 are fixedly connected at the edge positions of the test tube holes 4, which can protect the reagent tubes and reduce the scratches caused by the friction between the reagent tubes and the test tube holes 4, and a clamping assembly is arranged at the step between the placement plate 3 and the storage box 1;

[0024] A partition 8 is arranged on the inner wall of the storage box 1 near the bottom surface, a sponge pad 9 is mounted on the top surface of the partition 8, and a refrigeration component is arranged on the lower side of the partition 8.

[0025] Among them, the thickness of the sponge pad 9 is relatively large. When the reagent tube is inserted into the reagent hole, the bottom of the reagent tube contacts the sponge pad 9. When the reagent tubes are stacked, the sealing cover 2 is closed, and the pressure of the sealing cover 2 is used to slightly press down the reagent tube, so that the reagent tube squeezes the sponge pad 9. The elastic performance of the sponge pad 9 can be used to keep the reagent tube in a fixed state, effectively improving its stability.

[0026] like Figure 5 As shown, the snap-on assembly includes a diamond ring 5 fixedly connected to the bottom surface of the placement plate 3, a groove 6 is opened at the step of the inner wall of the storage box 1, and two arc blocks 7 are fixedly connected to the side wall of the groove 6, and the diamond ring 5 is adapted to the groove 6.

[0027] Among them, the clamping method of the diamond ring 5 and the arc block 7 is a conventional setting in the existing mechanical structure, so it will not be described in detail in this solution.

[0028] like Figure 2 and Figure 4As shown, the refrigeration assembly includes two semiconductor refrigeration plates 10 installed on the lower side of the partition 8, the semiconductor refrigeration plate 10 is fixedly connected to a heat dissipation fin 11 on the side wall away from the center of the storage box 1, and a heat dissipation fan 12 is installed on the heat dissipation fin 11. A heat dissipation hole 19 is opened on the side wall of the storage box 1 at the heat dissipation fan 12, a refrigeration fin 13 is fixedly connected to the other side of the semiconductor refrigeration plate 10, and a refrigeration fan 14 is installed on the side wall of the refrigeration fin 13. A protective cover 21 is fixedly connected to the inner wall of the storage box 1 at the semiconductor refrigeration plate 10, and a flow guide assembly is arranged on the lower side of the partition 8.

[0029] Specifically, the semiconductor cooling sheet 10 is used as follows:

[0030] Heat dissipation method: The semiconductor cooling chip 10 generates heat when working, so a heat dissipation method is needed to effectively dissipate the heat. Common heat dissipation methods include using heat sinks and fans to accelerate the dissipation of heat;

[0031] Power connection: The semiconductor cooling sheet 10 requires an external power supply to work. Usually a DC power supply is used, and the appropriate power supply voltage and current are selected according to the specifications and requirements of the cooling sheet; a lithium battery can also be installed in the storage box 1 for power supply according to actual conditions.

[0032] Temperature control: The semiconductor cooling chip 10 can achieve cooling and heating by controlling the direction and magnitude of the current. By changing the direction of the current, the cooling chip can absorb heat from one side and dissipate it to the other side. Temperature control can be achieved by a microcontroller or a thermostat, adjusting the magnitude and direction of the current as needed to achieve the desired temperature.

[0033] like Figure 2 and Figure 3 As shown, the flow guide assembly includes a flow guide pipe 15 fixedly connected between the protective covers 21 on both sides, the flow guide pipe 15 is connected to the protective covers 21, a shunt pipe 16 is fixedly connected to the side wall of the flow guide pipe 15, the other end of the shunt pipe 16 passes through the storage box 1 and is fixedly connected to a hose 17, a hollow plate 18 is fixedly connected to the bottom surface of the sealing cover 2, a plurality of air holes are opened on the bottom surface of the hollow plate 18, and the hose 17 is connected to the hollow plate 18.

[0034] Through the mutual cooperation among the storage box 1, the sealing cover 2, the placement plate 3, the refrigeration component and the guide component, the low-temperature airflow generated by the semiconductor refrigeration plate 10 can be introduced into the sealing cover 2 and evenly sink from multiple through holes, which is convenient for constant temperature refrigeration of reagents, and effectively solves the problems of large fluctuations and inaccuracies in analysis data caused by inconsistent actual temperatures in the traditional way.

[0035] The working principle of the utility model is as follows: first, the reagents are placed in the test tube holes 4 in sequence, and then the sealing cover 2 is closed. When the reagents need to be refrigerated or transported, the semiconductor refrigeration sheet 10, the heat dissipation fan 12 and the cooling fan 14 are started by an external power supply. The heat generating side of the semiconductor refrigeration sheet 10 uses the heat dissipation fan 12 to discharge the hot air flow through the heat dissipation holes 19, and the cooling side of the semiconductor refrigeration sheet 10 guides the cold air flow into the guide tube 15 through the cooling fan 14. The cold air flow is ejected from the through hole on the hollow plate 18 through the shunt tube 16 and the hose 17, and the ejection position is at the top of the reagent. Due to the large density of the cold air flow, the ejected cold air flow begins to sink to the bottom of the reagent, thereby maintaining the temperature of the reagent consistent, which is beneficial to the data accuracy during the subsequent blood cell analysis.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
