Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a constant temperature temporary storage device for test samples. Background Art

[0002] The collection and transportation of clinical laboratory samples is a common practice in medical care and is a crucial step in the collection of test samples for clinical drug research. According to the "Expert Consensus on Standardization of Transport and Storage of Clinical Laboratory Samples," the storage environment and transportation time limits for commonly tested items are as follows: some samples, such as those for renal function and immunoglobulins, can be sent for testing at room temperature; some samples, such as those for blood oxygenation, routine blood counts, and erythrocyte sedimentation rate, require placement on ice or refrigeration for testing; and some samples, such as those for genetic testing, require cryopreservation and then transportation across longer distances, such as across hospital campuses.

[0003] However, in practice, clinical laboratory samples are difficult to transport and store in strict accordance with these requirements. This is especially true for hospitalized patients, whose clinical laboratory samples are often collected between 6:00 and 7:00 in the morning by medical staff. After collection is complete, they are collected by field staff around 7:00 to 8:30 and finally sent to the laboratory for sorting and testing. The collection process alone can take nearly an hour, and the entire process, from sample collection to laboratory testing, can take two hours or even longer. During this process, various samples are stored in racks at room temperature, reducing the safety and effectiveness of sample storage and increasing the instability of test results.

[0004] Chinese utility model patent publication number CN221268205U discloses a thermostatic box for storing test tubes for laboratory testing. The box comprises a thermostatic box body and a thermostatic control module. The thermostatic box body defines a thermostatic storage chamber within which a test tube rack is mounted via a lifting mechanism. This chamber provides a constant temperature environment, preventing samples from being stored for extended periods of time during sampling, which can affect the accuracy of test results. However, the above thermostatic box only has a single storage chamber, failing to address the need for different storage environments for different types of samples. Utility Model Content

DETAILED DESCRIPTION

[0027] The preferred embodiment of the present invention is described below with reference to the accompanying drawings. It should be understood that the test sample constant temperature temporary storage device described herein is a preferred embodiment and is only used to illustrate and explain the present invention, and does not constitute a limitation of the present invention.

[0028] The directional terms or positional relationships such as "up", "down", "left" and "right" described in the present invention are based on the directional relationships in the drawings of the present invention specification and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the content protected by the present invention. Example

[0029] This embodiment Figures 1 to 5 As shown, a constant temperature temporary storage device for test samples includes a temporary storage box and a temporary storage box door that is buckled into the temporary storage box. A refrigeration system is arranged in the temporary storage box, and a sample rack is detachably placed in the temporary storage box.

[0030] Specifically, such as Figure 1 As shown, the temporary storage box is a box-like structure with an open top, made using a heat-insulating structure known in the art. Two parallel insulation panels are built into the temporary storage box along its height. The insulation panels divide the space formed within the temporary storage box, separating it into a first box 1, a second box 2, and a third box 3, which are independent of each other. The insulation panels use a heat-insulating plate structure known in the art to minimize the temperature of the three boxes from being affected by the temperature of adjacent boxes. Accordingly, the temporary storage door includes relatively independent first door 4, second door 5, and third door 6, which snap onto the first box 1, second box 2, and third box 3, respectively. All three doors are made using a heat-insulating structure known in the art. Each door is provided with a recessed portion 7 for facilitating door opening, allowing the first door 4, second door 5, and third door 6 to be opened independently. The heat-insulating structure described above can refer to the box structure of refrigerators, freezers, or refrigerators known in the art. In other embodiments, the temporary storage box can also be designed as a box-like structure with open sidewalls, with the temporary storage box door correspondingly snapped onto the sidewalls. Shock absorbers are installed at each of the four corners of the bottom of the temporary storage box to reduce vibration during transportation and prevent samples from being shaken. The shock absorbers in this embodiment use spring shock absorbers commonly used in the art.

[0031] In this embodiment, the temporary storage box door is movably fastened to the top of the temporary storage box body via a hinge. This arrangement makes opening and closing easy, and the integrated design makes it difficult to lose parts. In other embodiments, the temporary storage box door can also be provided independently and detachably fastened to the opening of the temporary storage box body.

[0032] To achieve independent temperature control of the temporary storage chambers, the refrigeration system installed in the temporary storage chambers is a refrigeration system with three independent cycles (not shown in the figure), compatible with the three chambers. Specifically, the three independent refrigeration cycle systems are installed in the mutually independent first chamber 1, second chamber 2, and third chamber 3, respectively, so that the internal temperatures of the first chamber 1, second chamber 2, and third chamber 3 can be independently controlled. Generally, the temperature modes of the three chambers are: freezing mode, refrigeration mode, and normal temperature mode. Since the temperatures in the three chambers can be independently controlled, any chamber can be set to freezing mode, refrigeration mode, or normal temperature mode. Therefore, in special circumstances, the mode of one or more of the chambers can be adaptively adjusted as needed. In this embodiment, the first chamber 1, second chamber 2, and third chamber 3 are of the same size. Of course, the three chambers can also be designed to vary in size, so that the largest chamber can be set to a storage temperature suitable for more samples. The refrigeration system with an independent three-cycle is an existing technology and will not be described in detail here. It should be noted that since the temporary storage device of this embodiment needs to be used in a mobile state, a battery (not shown in the figure) is fixed inside the temporary storage box to provide a mobile power source for the refrigeration system, and a charging port is provided on the temporary storage box to charge the battery regularly. The structure of the battery is an existing technology and will not be described in detail here.

[0033] like Figure 1 、 Figure 3 、 Figure 4 As shown, the first box 1, the second box 2 and the third box 3 can all be detachably placed with sample racks. Figure 4As shown, the sample rack includes an upper shelf 8 and a lower shelf 9. Each of these shelves is arrayed with 30 correspondingly positioned blood collection tube placement holes 10. "Corresponding" here means that the axes of the blood collection tube placement holes 10 on the upper and lower shelves 8 and 9 coincide. A shock-absorbing layer is fixed to the inner wall of the blood collection tube placement holes 10. Made of rubber, the inner wall of the shock-absorbing layer is larger than the outer diameter of the blood collection tube and smaller than the outer diameter of the blood collection tube cap. This allows the blood collection tube to be inserted into the blood collection tube placement holes 10 on the upper shelf 8 and retained in place by the blood collection tube cap. The upper and lower shelves 8 and 9 are connected by several connecting rods 11. These connecting rods 11 utilize a conventional telescopic rod structure. By extending and retracting the connecting rods 11, the height of the sample rack can be adjusted to accommodate blood collection tubes of varying heights. For samples other than blood collection tubes, the sample can be placed on either the upper shelf 8 or the lower shelf 9. Adjusting the height of the connecting rods 11 allows the sample rack to accommodate samples other than blood collection tubes.

[0034] The dimensions of the upper shelf 8 and the lower shelf 9 are slightly smaller than the internal dimensions of the corresponding boxes. A pair of slides 12 are provided in the opposite side walls of the first box 1, the second box 2, and the third box 3. Sliders 13 that match the slides 12 are fixed on the opposite side walls of the upper shelf 8, so that the sample rack can be slidably placed in the corresponding box. This improves the placement stability of the sample rack while ensuring that the sample rack is easy to disassemble. A pair of handrails can also be fixed on the top surface of the upper shelf 8 to further facilitate the disassembly of the sample rack. Due to the different temperatures in the three boxes, the sample racks in the three boxes are made of materials of different colors. For example, the sample rack in the room temperature mode box is made of yellow plastic material, the sample rack in the refrigeration mode box is made of blue plastic material, and the sample rack in the freezing mode box is made of green plastic material. This makes it easier to distinguish samples at different temperatures during transportation and sorting.

[0035] In order to further ensure the stability of the samples, Figure 1 、 Figure 5 As shown, the first door 4, the second door 5 and the third door 6 are all provided with a push plate 14 for pressing the sample in a sliding manner in the height direction. The setting direction of the push plate 14 is parallel to the setting direction of the corresponding door, and the size of the push plate 14 is smaller than the size of the internal space of the corresponding box. The push plate 14 can be made of a material with a certain elasticity, such as rubber, or it can be made of a hard material, and a soft buffer layer is fixed on the lower end surface of the push plate 14 to avoid damage to the sample. In this embodiment, the first door 4, the second door 5 and the third door 6 are all slidably penetrated by a pressing component, and the push plate 14 is fixed to one end of the pressing component located in the corresponding box. Specifically, as Figure 2 、 Figure 5As shown, the clamping member in this embodiment is a handle 15, which is equal to or slightly larger than the through-hole opened in the corresponding door. In this embodiment, a rubber layer is fixed in the through-hole of the door, so that the handle 15 slides through the corresponding door with damping and has a certain degree of heat preservation. With this arrangement, the height of the support plate 14 can be adjusted by pulling the handle 15 up and down. Of course, in other embodiments, the support plate 14 can also be connected to the corresponding door through other clamping members, such as a clamping member that is threaded and penetrates the corresponding door, and the height of the support plate 14 can be adjusted by screwing the clamping member.

[0036] When using this embodiment to collect test samples, it is placed on a wheeled rack for easy transfer. After sample collection, the temperature chamber is opened. Blood collection tubes are placed in the tube placement holes 10 of the sample rack. Other samples are packaged as required and placed on the upper shelf 8 or lower shelf 9. The handle 15 is then pulled up or down to adjust the height of the abutment plate 14, allowing it to gently press against the sample. After all samples have been collected, the sample rack is removed and all samples on the rack are transferred.
