[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a blood specimen transfer box for hematology. BACKGROUND

[0002] Blood is a kind of red opaque viscous liquid flowing in the blood vessels and heart of human. Blood is composed of blood plasma and blood cells, and one liter of blood plasma contains 900-910g of water, 65-85g of protein and 20g of low molecular substances, and the low molecular substances contain various electrolytes and organic compounds, and the blood cells include three types of cells, i.e. red blood cells, white blood cells and platelets. The function of blood contains two parts of blood cell function and blood plasma function, and has four functions of transportation, regulation of human body temperature, defense and regulation of human body osmotic pressure and acid-base balance. At present, blood sample detection is needed when simple physical examination or hospitalization treatment is carried out.

[0003] When blood sample detection is carried out, the blood collection tube after blood collection is generally not directly sent to the laboratory for blood detection, and usually the blood collection tube is placed on the test tube rack, and after blood collection of multiple patients is completed, the blood specimens of the multiple patients are uniformly sent to the laboratory by medical staff for detection. Therefore, the blood specimen exists a waiting period between blood collection and detection. In the waiting period, the blood specimen is affected by temperature, waiting time and other factors, and may appear hemolysis and other phenomena, which may affect the accuracy of the detection result. Therefore, it is necessary to design a transfer box for storing blood specimens and having a blood specimen collection time reminding function. CONTENT OF THE UTILITY MODEL

Moreover, the blood collection tube is threadedly connected in the mounting hole, which can avoid shaking of the blood collection tube relative to the box, thereby smoothly transporting the blood sample. In addition, the refrigeration assembly in the scheme can reduce the temperature in the box, ensuring that the blood sample is stored at low temperature, thereby avoiding the influence of high storage temperature on the accuracy of the test result.

[0013] Optionally, the number of heat dissipation holes is two or more, and a heat dissipation fan is arranged in one heat dissipation hole.

[0014] In the scheme, the heat dissipation fan is used to accelerate the airflow speed in the heat dissipation cavity, thereby improving the heat dissipation effect.

[0015] Optionally, a temperature sensor is provided inside the refrigeration chamber, and a temperature display screen is provided on the outer wall of the cabinet. The temperature display screen is used to display the temperature value detected by the temperature sensor.

[0016] In this solution, a temperature sensor inside the refrigeration chamber monitors the temperature in real time.

The temperature sensor transmits the detected temperature signal to the digital display temperature controller, and the digital display temperature controller controls the semiconductor cooling chip to work according to the received temperature signal.

[0018] In this solution, medical staff can not only monitor the temperature inside the refrigeration chamber through the digital temperature controller, but also set the storage temperature range for blood samples. When the temperature inside the refrigeration chamber is lower than the preset low value, the digital temperature controller controls the semiconductor cooling chip to not work. When the temperature inside the refrigeration chamber is higher than the preset high value, the digital temperature controller controls the semiconductor cooling chip to work, thereby achieving automated temperature control.

[0031] Embodiment one

[0032] The embodiment is basically as shown in Figure 1 and Figure 2 : a blood specimen transport case for blood department, including box 1, the top of box 1 is open, and the top of box 1 is hinged with the box cover 2 for covering the top opening of box 1 by hinge, and the box cover 2 is equipped with buckle 3 between box 1, and the buckle 3 is used to buckle the box cover 2 with box 1.

[0033] The front outer side wall of box 1 is equipped with timer 4 by screw, and as shown in Figure 3 and Figure 4 , box 1 is equipped with fixing seat 5 and refrigeration assembly. The bottom wall of fixing seat 5 is integrally formed with box 1, and a plurality of mounting holes 501 for inserting blood collection tube 6 are formed in fixing seat 5, and a threaded section I is arranged on the inner peripheral wall of mounting hole 501, and a threaded section II is arranged on the outer peripheral wall of blood collection tube 6, so that medical staff can vertically fix blood collection tube 6 on fixing seat 5 by rotating blood collection tube 6, to avoid shaking of blood collection tube 6 relative to box 1.

[0034] The mounting hole 501 in the same longitudinal row of mounting holes 501 is equipped with switch assembly, and the number of timer 4 and switch assembly is same, and timer 4 and switch assembly one-to-one correspond. The switch assembly includes conductive sheet I 7 and conductive sheet II 8, the conductive sheet I 7 is welded to the hole bottom wall of mounting hole 501, one end of conductive sheet II 8 is welded to the hole bottom wall of mounting hole 501, the other end of conductive sheet II 8 is located above conductive sheet I 7, and conductive sheet II 8 is copper elastic sheet; after blood collection tube 6 is inserted into mounting hole 501, conductive sheet II 8 is pushed and extruded to contact with conductive sheet I 7, and the corresponding timer 4 starts timing.

[0035] The refrigeration assembly comprises two ice bags 9, and gaps exist between the left and right sides of the fixing seat 5 and the inner side walls of the box body 1, and the two ice bags 9 are respectively located in the two gaps. In this way, the ice bags 9 can absorb the heat inside the box body 1, so as to reduce the temperature inside the box body 1 and realize low-temperature storage of the blood samples. Moreover, the water droplets condensed on the surface of the ice bags 9 will flow into the gaps and will not affect the blood collection tubes 6 on the fixing seat 5. The side walls of the box body 1 and the inner side walls of the box cover 2 are provided with heat insulation layers 10, so as to reduce the heat exchange between the inside and outside of the box body 1.

[0036] In actual use, after the medical staff complete blood collection each time, the blood collection tube 6 containing the blood of a patient is screwed into the installation hole 501, and the blood collection tube 6 is screwed into the installation hole 501 in the order of the longitudinal direction of the installation hole 501. In this way, when the blood collection tube 6 is screwed into the installation hole 501 located at the first position in each longitudinal row of installation holes 501, the blood collection tube 6 is in threaded connection with the installation hole 501, and the bottom end of the blood collection tube 6 gradually approaches the hole bottom of the installation hole 501. In the process, the bottom end of the blood collection tube 6 exerts downward pressure on the conductive sheet II 8, forcing the conductive sheet II 8 to bend downward and contact the conductive sheet I 7 (as shown in FIG. 8), and the switch assembly is closed, and the corresponding timer 4 starts timing. Similarly, when the blood collection tube 6 is screwed into the installation hole 501 located at the last position, the switch assembly in the installation hole 501 is closed, and the corresponding timer 4 starts timing. In this way, the medical staff can master the blood collection time period of the blood collection tube 6 in the corresponding longitudinal row through the two timers 4 in the same longitudinal row, so as to remind the medical staff to timely send the blood samples for detection, avoid the blood samples waiting for too long, and ensure the accuracy of the detection results. Figure 4

[0037] In addition, the medical staff can take out the blood collection tube 6 by reversely rotating the blood collection tube 6. At the same time, the conductive sheet II 8 in the installation hole 501 is reset without pressure, the conductive sheet II 8 no longer contacts the conductive sheet I 7, the switch assembly is opened, and the corresponding timer 4 stops working, waiting for the next timing.

[0038] In summary, in the embodiment, the blood collection tube 6 is screwed into the installation hole 501, which can not only ensure that the blood collection tube 6 is vertically placed and will not shake relative to the box body 1, but also trigger the corresponding timer 4 to start timing and remind the medical staff to timely send the blood samples for detection. Moreover, the ice bags 9 are used to realize low-temperature storage of the blood collection tube 6, avoid the influence of high temperature on the blood samples, and ensure the accuracy of the detection results.
