Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a blood sample transport box. Background Technology

[0002] In the blood drawing room, after drawing blood from a patient, the blood sample is sent to the laboratory for testing. Currently, many patients' blood samples need to be sent outside the hospital for testing. Nurses transport the test tubes in transport boxes, but the test tube racks in these boxes can shake and collide during transport, easily causing denaturation of hemolytic proteins and reduced activity of clotting factors in the blood. This affects the quality of blood products, consequently impacting test results, wasting patients' time and money, and even delaying diagnosis and treatment. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a blood sample transport box to reduce the impact on the quality of blood samples during transport.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] This application provides a blood sample transport box, comprising: a box body, the box body including a first outer shell and a first heat insulation layer stacked together, the box body having a receiving space, the top of the receiving space having an opening, and the bottom of the receiving space having a first snap-fit ​​member; a cover, the cover including a second outer shell and a second heat insulation layer stacked together, the cover being rotatably connected to the box body and used to open or close the opening; at least one isolation bracket, the isolation bracket being disposed within the receiving space and spaced apart from the first heat insulation layer, the isolation bracket having multiple ventilation openings; a phase change material layer, the phase change material layer being disposed between the isolation bracket and the first heat insulation layer; and a test tube rack, the test tube rack including an upper fixing plate, a connector, and a base, the base having a second snap-fit ​​member on the side facing the bottom of the receiving space, the second snap-fit ​​member engaging with the first snap-fit ​​member, the upper fixing plate having multiple placement holes, the upper fixing plate having the connector at opposite ends, the connector being detachably connected to the base.

[0028] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] In the blood drawing room, after drawing blood from a patient, the blood sample is sent to the laboratory for testing. Currently, many patients' blood samples need to be sent outside the hospital for testing. Nurses transport the test tubes in transport boxes, but the test tube racks in these boxes can shake and collide during transport, easily causing denaturation of hemolytic proteins and reduced activity of clotting factors in the blood. This affects the quality of blood products, consequently impacting test results, wasting time and money for patients, and even delaying diagnosis and treatment.

[0033] To address the aforementioned technical problems, this application provides a blood sample transport box.

[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a blood sample transport box provided in some embodiments of this application. Figure 2 This is a schematic diagram of a blood sample transport box provided in some other embodiments of this application. The blood sample transport box 100 may include a box body 1, a cover 2, at least one isolation support 3, a phase change material layer 4, and a test tube rack 5.

[0035] The enclosure 1 includes a first outer shell 11 and a first heat insulation layer 12 stacked together, with the first heat insulation layer 12 located inside the first outer shell 11. By setting the first heat insulation layer 12, heat from the external environment can be blocked from the enclosure 1.

[0036] For example, the first outer shell 11 can be made of plastic, metal, etc., and the surface of the first outer shell 11 can be provided with anti-slip texture, which helps to improve the anti-slip performance of the box 1. The surface of the first outer shell 11 can also be provided with reinforcing ribs, which helps to improve the structural strength of the box 1.

[0037] For example, the first insulation layer 12 may be made of materials such as polyurethane foam, polystyrene foam, or vacuum insulation board, and this application does not limit it.

[0038] The housing 1 has a receiving space 13, and the top of the receiving space 13 has an opening 131. Specifically, the first outer shell 11 and the first heat insulation layer 12 enclose the receiving space 13, and items can be placed into the receiving space 13 through the opening 131 at the top of the receiving space 13.

[0039] The shape of the accommodating space 13 can be designed as needed, and this application does not limit it.

[0040] The cover 2 is rotatably connected to the housing 1 and is used to open or close the opening 131. Specifically, one end of the cover 2 can be rotatably connected to the housing 1. By rotating the cover 2, the opening 131 can be opened or closed, thereby achieving a seal on the containing space 13.

[0041] The connection between the cover 2 and the box 1 can be equipped with a sealing strip to prevent hot air from the external environment or cold air from the containment space 13 from escaping.

[0042] The isolation bracket 3 is disposed within the receiving space 13 and spaced apart from the first heat insulation layer 12. There can be one or more isolation brackets 3. For example, the isolation bracket 3 can be connected to the housing 1 by means of adhesive bonding, fastener connection, snap-fit, etc.

[0043] For example, the isolation bracket 3 can be a partition with low thermal conductivity.

[0044] Multiple vents 31 are formed on the isolation bracket 3, and the phase change material layer 4 is disposed between the isolation bracket 3 and the first heat insulation layer 12. Specifically, when the phase change material layer 4 melts at a set phase change temperature, it can absorb heat from the vents 31, thereby maintaining the temperature inside the containment space 13 at a lower temperature. When the phase change material layer 4 solidifies at a set temperature, it releases heat from the vents 31, thereby maintaining the temperature inside the containment space 13 at a higher temperature.

[0045] For example, the phase change material layer 4 can be a water-based gel, paraffin wax with a specific melting point, etc.

[0046] The test tube rack 5 may include a base 53. A second snap-fit ​​element is provided on the side of the base 53 facing the bottom of the receiving space 13, and a first snap-fit ​​element is provided at the bottom of the receiving space 13. The second snap-fit ​​element engages with the first snap-fit ​​element. Thus, through the engagement between the first and second snap-fit ​​elements, a detachable connection can be achieved between the base 53 and the housing 1, and the base 53 can also be fixed in place.

[0047] The test tube rack 5 may also include an upper fixing plate 51 and a connector 52. The upper fixing plate 51 has multiple placement holes 511, through which blood samples can be placed on the test tube rack 5. Multiple upper fixing plates 51 can be provided, and these plates can be spaced apart along the height of the test tube rack 5.

[0048] The upper fixing plate 51 has connectors 52 at opposite ends, and the connectors 52 are detachably connected to the base 53. Since the size of the upper part of the blood sample is larger than the size of the placement hole 511, when the blood sample needs to be removed, the connectors 52 and the upper fixing plate 51 can be directly removed, which helps to improve work efficiency and prevents omissions.

[0049] The connector 52 and the base 53 can be detachably connected by means of snap-fit, magnetic attraction, fasteners, etc.

[0050] According to the blood sample transport box 100 of this application embodiment, by providing a phase change material layer 4 in the accommodating space 13 of the box body 1 and separating the phase change material layer 4 from the blood sample by the isolation bracket 3, local overcooling or overheating can be avoided. At the same time, the required temperature can be provided for the transport of blood samples, thereby preventing the test results from being affected by the transport. In addition, the bottom tray 53 of the test tube rack 5 is detachably connected to the box body 1, which can fix the bottom tray 53 and help reduce the collision of the test tube rack 5. The detachable connection between the connector 52 and the bottom tray 53 makes it easy for the test personnel to directly take out multiple blood samples, thereby saving time and reducing omissions.

[0051] Please continue reading. Figure 1 and Figure 2 In some embodiments, an elastic buffer layer is provided around the outer periphery of the base 53. This elastic buffer layer surrounding the outer periphery of the base 53 reduces impacts to the test tube rack 5, thereby improving the reliability of the blood sample transport box 100 during transport.

[0052] Please continue reading. Figure 1 and Figure 2In some embodiments, the surface of the phase change material layer 4 facing the isolation support 3 is corrugated. This helps to increase the heat exchange area between the phase change material layer 4 and the air.

[0053] Please continue reading. Figure 1 and Figure 2 In some embodiments, the blood sample transport box 100 may also include a fan disposed within the containment space 13 and opposite the phase change material layer 4. This allows air to circulate within the containment space 13, thereby enabling a more uniform temperature distribution within the containment space 13 and preventing localized overheating or overcooling.

[0054] Please continue reading. Figure 1 and Figure 2 In some embodiments, the blood sample transport box 100 may also include a thermoelectric cooler. The thermoelectric cooler is disposed within the receiving space 13. Thus, active temperature control can be achieved through the thermoelectric cooler, thereby better ensuring the transport of blood samples.

[0055] For example, a semiconductor cooler may include a cooling module, a heat dissipation module, a power supply module, and a control module. The cooling module is disposed within the housing 13 and is used to conduct cold energy into the housing 13. The heat dissipation module is disposed outside the housing 1 and is used to dissipate the generated waste heat to the external environment. The power supply module is used to provide a stable direct current, and the control module is used to control the cooling or heating.

[0056] Please continue reading. Figure 1 and Figure 2 In some embodiments, multiple clips 6 may be provided on the side wall of the receiving space 13. The clips 6 are detachably connected to the connectors 52. Specifically, the clips 6 may be spaced apart in the circumferential direction of the receiving space 13, and the connectors 52 are inserted into the clamping space of the clips 6. Thus, the connectors 52 can be fixed by multiple clips 6, thereby reducing the shaking of the test tube rack 5 and further reducing the collision of blood samples during transportation.

[0057] Please continue reading. Figure 1 and Figure 2 In some embodiments, the clip 6 is slidably connected to the housing 1. This allows the position of the clip 6 to be adjusted according to the different sizes of the test tube rack 5, thereby improving the versatility of the blood sample transport box 100.

[0058] Please continue reading. Figure 1 and Figure 2In some embodiments, the sidewall of the receiving space 13 is provided with multiple grooves 14, and the clip 6 is slidably disposed in the grooves 14. This arrangement is simple in structure and allows the clip 6 to slide along the extension direction of the grooves 14, thereby helping to reduce the manufacturing cost of the blood sample transport box 100.

[0059] Please continue reading. Figure 1 and Figure 2 In some embodiments, the blood sample transport box 100 may also include a fixing member. A plurality of first fixing holes 15 are provided on one side of the slide 14, and the plurality of first fixing holes 15 are spaced apart along the extension direction of the slide 14. The clip 6 is provided with a second fixing hole 61, and the fixing member passes through the first fixing hole 15 and the second fixing hole 61.

[0060] Please continue reading. Figure 1 and Figure 2 In some embodiments, the blood sample transport box 100 further includes a fixing member. A plurality of first fixing holes 15 are provided on one side of the slide 14, and the plurality of first fixing holes 15 are spaced apart along the extending direction of the slide 14. The clip 6 is provided with a second fixing hole 61, and the fixing member passes through the first fixing hole 15 and the second fixing hole 61. Thus, the clip 6 can be fixed by the cooperation between the first fixing hole 15, the second fixing hole 61, and the fixing member, and the fixing method is simple, thereby helping to reduce the manufacturing cost of the blood sample transport box 100.

[0061] Please continue reading. Figure 1 and Figure 2 In some embodiments, a handle 54 is provided at the end of the connector 52 away from the base 53. This allows the upper fixing plate 51 and the connector 52 to be directly removed via the handle 54, thereby improving the user experience.
