Description

Technical Field

[0001] The utility model relates to the technical field of biological sample transport boxes, in particular to an intelligent biological sample transport box. Background Art

[0002] A biological sample transport box is a container specially used for transporting biological samples. It can keep the samples at an appropriate temperature to prevent them from deteriorating or being contaminated. It is generally used in hospitals, clinics, laboratories and other places for the collection, transportation and temporary storage of biological samples.

[0003] The existing biological sample transport box generally includes a transport box body and a storage box arranged therein. The storage box is provided with multiple layers of mesh plates above and below for placing sample reagents. When the reagents need to be taken out, all the sample reagents on the mesh plate are taken out through the operating block on the mesh plate. When the reagent samples are taken out from the mesh plate, they need to be searched and taken out according to the order of sampling time. This process takes a certain amount of time and effort. However, the operation of taking out the sample reagents as a whole and then searching for a single sample reagent in the prior art not only shortens the subsequent refrigeration time of the sample reagents and affects their preservation quality; and in the process of taking out the sample reagents, the sample reagents taken out each time cannot be recorded, which may cause the phenomenon of mismatch or confusion of the number of reagent samples. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a biological sample intelligent transportation box.

[0005] The technical solution of this utility model is as follows:

[0006] A biological sample intelligent transport box comprises a box body with a main control module, a cold box layer is arranged on the inner wall of the box body, a sample placement rack for placing sample reagent tubes is arranged on the inner side of the cold box layer, a unique label is arranged on the outer wall of each sample reagent tube, the sample placement rack comprises a rack body and a heat preservation positioning layer, a positioning hole plate and a base which are sequentially distributed on the rack body from top to bottom, the heat preservation positioning layer, the positioning hole plate and the base are all provided with a plurality of vertical test tube slots arranged correspondingly, the sample reagent tubes can be vertically inserted downward from the vertical test tube slots of the heat preservation positioning layer into the vertical test tube slots arranged on the base, when taking out the corresponding sample reagent tubes individually, it is not necessary to take out all the sample reagent tubes in the box body and then perform the search operation, which can be completed directly in the box body, and by providing the heat preservation positioning layer, other sample reagent tubes that do not need to be taken out can be kept warm, thereby reducing the influence on the preservation quality of other sample reagent tubes;

[0007] To facilitate the management of sample reagent tubes, the main control module is electrically connected to multiple pressure sensors. A pressure sensor is provided on the upper end face of each vertical test tube slot of the base. Each pressure sensor is numbered. The bottom of the sample reagent tube contacts the detection surface on the upper end of the pressure sensor to detect whether the sample reagent tube is taken out. A scanner that cooperates with the label is provided on the outside of the box. Each pressure sensor and the scanner are respectively connected to the communication end of the main control module. When the corresponding sample reagent tube needs to be taken out, the sample reagent tube is lifted up. When the corresponding pressure sensor below detects a change in pressure, the pressure sensor will transmit an electrical signal of the pressure change to the main control module, and then the label of the taken out sample reagent tube is placed on the scanner for recording. The signal detected by the numbered pressure sensor and the data information scanned by the scanner can realize the sample reagent tube outbound record operation.

[0008] The above-mentioned method, when taking out the sample reagent tube, if you forget to scan the label on the sample reagent tube on the scanner, there will be a phenomenon of omission. It also includes a time module and an alarm module arranged on the box body. The time module and the alarm module are respectively connected to the communication end of the main control module. When the sample reagent tube is taken out of the sample placement rack, if the pressure change time of the corresponding pressure sensor exceeds the timeout alarm threshold preset by the time module, the main control module will start the alarm module to alarm, which serves as a reminder to the staff.

[0009] Regarding the specific structure of the thermal insulation positioning layer, the thermal insulation positioning layer includes an upper thermal insulation layer and a lower thermal insulation layer which are arranged vertically, and vertical test tube slots are provided thereon. The upper thermal insulation layer is elastic, and the inner diameter of the vertical test tube slot thereon is smaller than the outer diameter of the sample reagent tube, and the upper thermal insulation layer can not only keep the sample reagent tube warm, but also have a certain clamping effect, thereby preventing the sample reagent tube from shaking up and down during transportation.

[0010] If the lower insulation layer is also made of a soft insulation material with elasticity, the middle of the sample reagent tube is positioned only by the middle positioning hole plate, and the upper part of the sample reagent tube may shake. For this reason, the lower insulation layer is an insulation layer made of a hard material, and its thickness is less than that of the upper insulation layer, and the positioning hole plate is used to limit the sample reagent tube.

[0011] The structure of the upper insulation layer is that the thickness of the upper insulation layer is 1-5 cm.

[0012] In order to facilitate the installation of the pressure sensor in the vertical test tube slot of the base, the pressure sensor is selected as a foil resistance strain gauge sensor.

[0013] In order to facilitate the management of the temperature and humidity inside the box, a temperature sensor and a humidity sensor electrically connected to the main control module are provided inside the box, and a display screen electrically connected to the main control module is provided outside the box. The display screen is used to display the temperature and humidity inside the box.

[0014] During transportation, the box may shake, which may cause the sample reagent tube to detach from the pressure sensor, resulting in a false alarm. To avoid false alarms, a protective cover is provided above the sample placement rack in the box. One side of the protective cover is hinged to the inner wall of the box, and the other side is connected to the box through an electromagnet. The electromagnet is electrically connected to the main control module. If during transportation, the electromagnet is closed and the protective cover is locked in the box, the alarm module sounds an alarm. Based on the closed state of the electromagnet, it can be quickly determined that the alarm is a false alarm, not that the staff took out the sample reagent tube without scanning it. The alarm can be eliminated at the remote terminal.

[0015] A power supply module is provided inside the box, and the power supply module includes a battery and an AC-DC conversion module. The battery is electrically connected to the AC-DC conversion module, and the battery is connected to the power drive end of the main control module.

[0016] The beneficial effects of the utility model are:

[0017] When taking out the required sample reagent tube, you can directly search and take it out in the box. When you open the box cover, the heat preservation positioning layer cooperates with the low temperature released by the cold box layer in the box to delay the temperature rise and reduce the storage quality of the sample reagent tube that has not been taken out;

[0018] The upper insulation layer of the insulation positioning layer can also play a certain clamping effect on the sample reagent tube to prevent the sample reagent tube from shaking during transportation, causing the bottom of the sample reagent tube to separate from the pressure sensor and causing the main control module to malfunction;

[0019] When the sample reagent tube is taken out of the sample placement rack, if the pressure change time of the corresponding pressure sensor exceeds the timeout alarm threshold preset by the time module, the main control module will start the alarm module to alarm, which will serve as a reminder to the staff. At the same time, the main control module can upload the test data to the remote terminal in real time, which is convenient for the management of the sample reagent tube;

[0020] A time module is also set up to compare the short time that the sample reagent tube is separated from the pressure sensor with the timeout alarm threshold. If the time does not exceed the timeout alarm threshold and the tube is returned to its original position, the alarm module will not be activated. If the sample reagent tube is separated from the pressure sensor for a long time due to bumps and the time exceeds the timeout alarm threshold, an alarm will be triggered to remind the staff transporting the box that the box may be tilted or the sample reagent tube is separated from the sample rack, and the box or the sample reagent tube should be returned to its original position in time to avoid leakage of the sample reagent tube.

[0029] See also Figure 1 and Figure 2 The biological sample intelligent transport box shown in the figure includes a box body 1 with a main control module, the box body 1 includes a box cover, and the four inner side walls and the bottom surface of the box body 1 are provided with a cold box layer 2. The cold box layer 2 is filled with a refrigerant, which can maintain the box body 1 at a temperature suitable for storing sample reagents. A sample placement rack for placing sample reagent tubes 8 is provided on the inner side of the cold box layer 2, and each sample reagent tube 8 is provided with a unique label on the outer wall.

[0030] Among them, the sample placement rack includes a rack body 3 and a heat-insulating positioning layer 4, a positioning hole plate 5 and a base 6 which are distributed on the rack body 3 in sequence from top to bottom. The heat-insulating positioning layer 4, the positioning hole plate 5 and the base 6 are all provided with a plurality of corresponding vertical test tube slots 7. The vertical test tube slots 7 on the heat-insulating positioning layer 4 and the positioning hole plate 5 are through-going vertical test tube slots 7. The vertical test tube slots 7 on the base 6 have a bottom surface for installing a pressure sensor 9. The sample reagent tube 8 can be vertically inserted downward from the vertical test tube slot 7 of the heat-insulating positioning layer 4 into the vertical test tube slot 7 of the base 6. When taking out the corresponding sample reagent tube 8 separately, it is not necessary to take out all the sample reagent tubes 8 in the box 1 and then perform the search operation. It can be completed directly in the box 1. By setting the heat-insulating positioning layer 4, other sample reagent tubes 8 that do not need to be taken out can be kept warm, thereby reducing the impact on the preservation quality of other sample reagent tubes 8.

[0031] See also Figure 3As shown, the specific structure of the thermal insulation positioning layer 4 is that the thermal insulation positioning layer 4 includes an upper thermal insulation layer 41 and a lower thermal insulation layer 42 arranged up and down, both of which are provided with a vertical test tube slot 7, and the thickness of the upper thermal insulation layer 41 is 1-5 cm. The upper thermal insulation layer 41 is elastic, and the inner diameter of the vertical test tube slot 7 thereon is smaller than the outer diameter of the sample reagent tube 8, and the maximum elastic deformation of the vertical test tube slot 7 thereon is greater than the outer diameter of the sample reagent tube 8, so that the upper thermal insulation layer 41 can not only play a role in heat preservation for the sample reagent tube 8, but also play a certain clamping effect, so as to avoid the sample reagent tube 8 from shaking up and down when the box 1 is transported. If the lower insulation layer 42 is also made of a soft insulation material with elasticity, the middle part of the sample reagent tube 8 is positioned only by the middle positioning hole plate 5, and the upper part of the sample reagent tube 8 may shake. For this reason, the lower insulation layer 42 is an insulation layer made of a hard material, and its thickness is less than that of the upper insulation layer 41, and cooperates with the positioning hole plate 5 to limit the sample reagent tube 8.

[0032] See also Figure 4 and Figure 5 As shown, in order to facilitate the management of the sample reagent tube 8, a power supply module and a plurality of pressure sensors 9 are provided in the box body, and the power supply module and the plurality of pressure sensors 9 are electrically connected to the main control module respectively. The power supply module is arranged in the bottom plate of the box body 1, and the power supply module includes a battery and an AC-DC conversion module. The battery is electrically connected to the AC-DC conversion module, and the battery is connected to the power drive end of the main control module. A pressure sensor 9 is provided on the upper end surface of each vertical test tube slot 7 of the base 6. The pressure sensor 9 is a prior art. In order to facilitate the installation of the pressure sensor 9 in the vertical test tube slot 7 of the base 6, the pressure sensor 9 is selected as a foil resistance strain gauge sensor. Each pressure sensor 9 is numbered. The bottom of the sample reagent tube 8 contacts the detection surface at the upper end of the pressure sensor 9 to detect whether the sample reagent tube 8 is taken out.

[0033] A scanner 10 is provided on the outside of the box 1 to cooperate with the label. The scanner 10 is a prior art and can upload the data of the label to a remote terminal for recording. Each pressure sensor 9 and the scanner 10 are respectively connected to the communication end of the main control module. When the corresponding sample reagent tube 8 needs to be taken out, the sample reagent tube 8 is lifted up. When the corresponding pressure sensor 9 below detects a pressure change, the pressure sensor 9 will transmit an electrical signal of the pressure change to the main control module, and then the label of the taken out sample reagent tube 8 is placed on the scanner 10 for recording. The signal detected by the numbered pressure sensor 9 and the data information scanned by the scanner 10 can realize the outbound recording operation of the sample reagent tube 8.

[0034] When taking out the sample reagent tube 8, if someone forgets to scan the label on the sample reagent tube 8 on the scanner 10, omission will occur. It also includes a time module and an alarm module arranged on the box body 1. The time module and the alarm module are respectively connected to the communication end of the main control module. The alarm module can be arranged on the outside of the box body 1. When the sample reagent tube 8 is taken out of the sample placement rack, if the initial time of the pressure change of the corresponding pressure sensor 9 to the time when the scanner 10 scans the label on the sample reagent tube 8 exceeds the timeout alarm threshold preset by the time module, the main control module will start the alarm module to alarm, which will serve as a prompt for the staff. If the scanner 10 detects a label for identification when the alarm module alarms, it will send the signal to the main control module, and the main control module will cancel the alarm. After the alarm is canceled, the time module is reset. At the same time, the main control module can upload the detection data to the remote terminal in real time, which is convenient for the management of the sample reagent tube 8.

[0035] In addition, the box 1 may vibrate during transportation. Even if an upper insulation layer 41 is provided, the bottom of the sample reagent tube 8 may be temporarily separated from the pressure sensor 9 due to bumps. For this reason, a time module is provided to compare the short time that the sample reagent tube 8 is separated from the pressure sensor 9 with the timeout alarm threshold. If the time does not exceed the timeout alarm threshold and the tube is returned to its original position, the alarm module will not be activated. If the sample reagent tube 8 is separated from the pressure sensor 9 for a long time due to bumps and the time exceeds the timeout alarm threshold, an alarm is triggered to remind the staff transporting the box 1 that the box 1 may be tilted or the sample reagent tube 8 may be separated from the sample placement rack. The box 1 or the sample reagent tube 8 should be returned to its original position in time to avoid leakage of the sample reagent tube 8.

[0036] In order to facilitate the management of the temperature and humidity inside the box 1, a temperature sensor and a humidity sensor electrically connected to the main control module are provided inside the box 1, and a display screen electrically connected to the main control module is provided outside the box 1. The display screen is used to display the temperature and humidity inside the box 1. The display screen, temperature sensor and humidity sensor are existing technologies and are no longer shown in the figure.

[0037] During transportation, the box 1 may shake, which may cause the sample reagent tube 8 to detach from the pressure sensor 9, resulting in a false alarm. To avoid false alarms, a protective cover is also provided in the box 1 above the sample placement rack. One side of the protective cover is hinged to the inner wall of the box 1, and the other side is connected to the box 1 through an electromagnet. Before taking out the sample reagent tube 8, it is necessary to cut off the power to the electromagnet, electrically connect the electromagnet to the main control module, and open the protective cover. If during transportation, the electromagnet is closed and the protective cover is locked in the box 1, the alarm module sounds an alarm. It can be quickly determined based on the closed state of the electromagnet that the alarm is a false alarm, not that the staff took out the sample reagent tube 8 without scanning it. The alarm can be eliminated at the remote terminal.
