Technical Field

[0001] This utility model relates to the field of pharmacokinetic research technology, specifically a portable pharmacokinetic sample carrying device. Background Technology

[0002] Pharmacokinetic sample is short for drug metabolism kinetic sample. In drug metabolism kinetic (PK) studies, it is a biological sample or related material collected from test subjects (such as humans, animals or in vitro models) to analyze the concentration of drugs and their metabolites. Most of these samples are biological body fluid samples, tissue samples and in vitro model samples. After the samples are collected, a receiving device is needed to store and transport these samples.

[0003] In the prior art, the patent with authorization publication number CN216710125U discloses a blood specimen transport box, which has some problems in actual use. For example, the test tubes need to be manually inserted into the slots at the appropriate angle to lock them in place, which is inconvenient. When the transport box is opened once, the top of the transport box is open, and the cold air escapes quickly. The elastic protrusion is not very stable when fixing the test tubes, and the test tubes themselves tend to shake when shaken. Utility Model Content

[0027] Please see Figure 1-8This embodiment provides a technical solution: a portable pharmacokinetic sample carrying device, including an outer box 1, with an inner box 2 inside the outer box 1. The outer box 1 is made of POM plastic material (polyoxymethylene). A polyurethane protective pad is fixed to the outer surface of the inner box 2. A cover plate 3 is provided on the upper side of the outer box 1. The top of the outer box 1 and the lower edge of the cover plate 3 need to be sealed with cosmetic rubber gaskets. The sealing between them can be achieved using a conventional sealing method. Handles 7 are rotatably connected to the front and rear sides of the outer box 1, and docking blocks 8 are respectively provided in the middle of the two handles 7. The left side of the outer box 1 is connected to... Limiting plates 9 are symmetrically fixedly connected to the right side, front and back. The front side of the docking block 8 has an arc-shaped docking groove, and the rear side of the docking block 8 has an arc-shaped docking block. The left side of the upper wall of the cover plate 3 is provided with a pressure relief valve 10 (the pressure relief valve 10 can be a miniature plastic check valve of model SCV1602DVL). The lower end of the pressure relief valve 10 extends to the lower side of the cover plate 3. When the cover plate 3 is closed, the two handles 7 can be rotated so that the arc-shaped docking block on the rear side of the docking block 8 is inserted into the arc-shaped docking groove on the front side of the docking block 8. At this time, the outer box 1 can be manually lifted and moved.

[0028] The device also includes a pick-and-place mechanism 4. The pick-and-place mechanism 4 includes a receiving groove 41, a guide rail 42, a guide groove 43, a storage rack 44, a card slot 45, a sliding groove 46, a card plate 47, and a spring 48. The receiving groove 41 is evenly distributed on the side wall of the inner box 2. The left and right sides of the receiving groove 41 are respectively provided with guide rails 42. The receiving groove 41 is provided with a storage rack 44. The left and right sides of the storage rack 44 are respectively provided with guide grooves 43. The inside of the guide grooves 43 is slidably connected to the outer surface of the guide rails 42 located at the same position. The upper right side of the storage rack 44 is respectively provided with a card slot 45. The upper side of the right side wall of the receiving groove 41 is respectively provided with a sliding groove 46. The inside of the sliding groove 46 is slidably connected with a card plate 47. The right side of the card plate 47 and the right side wall of the sliding groove 46 are respectively fixedly connected with a spring 48.

[0029] The retrieval mechanism 4 also includes a storage component 49, which includes a rotating frame 491, a container frame 492, and a limiting groove 493. A rotating rod is fixedly connected to the lower side of the rotating frame 491, and the rotating rod is rotatably connected to the lower side between the left and right inner walls of the storage rack 44. The storage rack 44 is fixedly connected to a uniformly distributed container frame 492. The lower surface of the storage rack 44 is provided with a limiting groove 493. The container frame 492 is provided with a screw tube 12. The lower side of the inner box 2 is provided with a dry ice storage chamber 5. The inner wall of the receiving groove 41 is provided with uniformly distributed rectangular holes 6.

[0030] The working principle of this utility model is as follows:

[0031] When the carrying device is needed, the storage rack 44 can be pulled out. When the storage rack 44 is pulled out, the locking plate 47 needs to be pushed to the right manually so that the locking plate 47 retracts into the slide groove 46. At this time, the rotating rod on the lower side of the tube holder 492 and the storage rack 44 maintain a rotatable connection, so the tube holder 492 will tilt forward or backward. After that, the tube holder 492 is restricted by the limiting groove 493. The maximum angle of the tube holder 492 tilting forward or backward is 30 degrees. At this time, it will no longer tilt. Then the screw tube 12 can be taken out, the screw tube 12 can be opened, and the pharmacokinetic sample can be placed inside the tube holder 492. After the screw tube 12 is placed, the storage rack 44 can be inserted back into the receiving groove 41.

[0032] During the insertion process, the guide rail 42 and guide groove 43 will restrict the vertical insertion path. The upper side of the card plate 47 is inclined, so when the retrieval rack 44 is inserted into the receiving groove 41, the lower right corner of the retrieval rack 44 will be attached to the inclined surface of the card plate 47, causing the card plate 47 to retract into the card plate 47.

[0033] When the storage rack 44 is fully inserted into the receiving slot 41, it will be affected by the elastic force of the spring 48 and push the card plate 47 to the left, so that the card plate 47 is re-inserted into the card slot 45 and the storage rack 44 is locked. Then dry ice can be added into the dry ice storage chamber 5. The dry ice needs to be wrapped in a cloth bag or a cloth bag to avoid direct contact between the dry ice and the box.

[0034] After completing the above steps, you can lift the inner box 2 and place it into the outer box 1, close the cover plate 3, and then turn the two handles 7 so that the arc-shaped docking block on the rear side of the docking block 8 is inserted into the arc-shaped docking groove on the front side of the docking block 8. At this time, you can manually lift the outer box 1 to move it.

[0035] During the sealing process of the outer box 1, the cold air sinks when the dry ice sublimates, creating a low-temperature zone in the inner box 2. At this time, the cold air is conducted through the rectangular hole 6, reducing the temperature of the entire inner box 2. When the inner box 2 is filled with too much carbon dioxide gas, causing unstable air pressure, the valve head of the pressure relief valve 10 opens to discharge the high-pressure gas, ensuring stable air pressure in the inner box 2. At the same time, the thermometer 11 measures the temperature of the inner box 2 in real time (the thermometer 11 can be a conventional alcohol red water thermometer).

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
