Description

Technical Field

[0001] The utility model relates to the technical field of medical testing equipment, in particular to an anaerobic bacteria specimen transport box. Background Art

[0002] Anaerobic bacteria are a type of strictly anaerobic bacteria that can only grow in an oxygen-free or low-oxygen environment. Anaerobic bacteria specimens need to be collected for bacterial culture and drug sensitivity testing in medical tests. However, anaerobic bacteria are extremely sensitive to oxygen. If the specimens are exposed to air after collection, the bacteria will die quickly, which brings difficulties to the test. Traditional anaerobic specimen transportation containers mainly use physical isolation from the air, which has poor oxygen exhaust effect, resulting in low bacterial survival rate and difficult to meet the needs of long-distance transportation; in addition, other biological specimens, such as viruses, bacteria, cells or tissue samples, need to be transported over long distances in medical tests. These specimens are also very sensitive to temperature changes and need to be transported in a low-temperature environment. Utility Model Content

The entire transport process is carried out in a sealed manner, and the interior of the transport box is always in a low-oxygen and low-temperature state by vacuuming and replacing inert gas, thereby ensuring the survival rate of anaerobic bacteria to the greatest extent.

DETAILED DESCRIPTION

[0019] See also Figure 1-3 , the embodiments of the utility model are further described;

[0020] An anaerobic bacteria specimen transport box comprises a box body 1 and a box cover 2 sealed on the top of the box body 1;

[0021] An observation window 21 is installed on the top of the box cover 2 through an opening and sealing, and the area of ​​the observation window 21 occupies 1 / 4 to 1 / 3 of the surface area of ​​the top of the box cover 2.

[0022] In this solution, the box body 1 is sealed with the box cover 2 to prevent outside air from entering the box body 1 after the box cover 2 is covered on the top of the box body 1; because anaerobic bacteria are a type of strictly anaerobic bacteria, after the anaerobic bacteria specimen is placed in the box body 1, a redox indicator is placed in the box body 1, and then the inside of the box body 1 is deoxygenated. During the deoxygenation process, the staff can check the color change of the redox indicator through the observation window 21 to confirm whether a low-oxygen environment is formed inside the box body 1; because the area of ​​the observation window 21 occupies 1 / 4 to 1 / 3 of the top surface area of ​​the box cover 2, a sufficient observation field of view can be guaranteed.

[0023] A metal heat-conducting frame 5 is detachably connected to the inside of the box body 1, and a cold source cabin 6 is provided inside the box body 1 below the metal heat-conducting frame 5;

[0024] An inert gas valve 3 and a temperature monitoring device 4 are installed on the box cover 2.

[0025] In this solution, the metal heat-conducting frame 5 can be installed inside the box body 1 by a detachable connection method such as embedding, clamping, or threaded connection.

[0026] When in use, the box cover 2 is opened, and the metal heat-conducting frame 5 is removed from the box body 1, and an ice bag or other refrigerant is placed in the cold source compartment 6, and the metal heat-conducting frame 5 is reinstalled in the box body 1. At this time, the refrigerant is in contact with the bottom of the metal heat-conducting frame 5, and the metal heat-conducting frame 5 has good thermal conductivity, and the cold source can be quickly transferred to the metal heat-conducting frame 5 to provide a low-temperature environment for the anaerobic bacteria specimen. The box cover 2 can be closed first to seal the inside of the transport box, and the temperature in the transport box can be tested by the temperature monitoring device 4 on the box cover 2, so as to adjust the number of cold sources in time and maintain it within the required low temperature range, and then the box cover 2 is opened again, and the culture dish or centrifuge tube containing the anaerobic bacteria specimen is quickly placed on the metal heat-conducting frame 5, 1-2 anaerobic culture bags and redox indicators are placed on the top of the box body 1 at the same time, and then the box cover 2 is covered on the top of the box body 1, so that the top of the box body 1 is sealed; the anaerobic culture bag completely or partially absorbs the oxygen in the enclosed space through chemical reactions, and produces carbon dioxide, thereby providing an anaerobic or low-oxygen growth environment for anaerobic microorganisms; the redox indicator is used to detect the oxygen concentration in the transport box; an external vacuum pump is connected to the inert gas valve 3, and vacuum is first evacuated for 2-5 minutes to remove most of the air in the box, and then high-purity nitrogen or carbon dioxide is slowly filled until normal pressure is restored; the redox indicator color change is checked through the observation window 21 to confirm whether a low-oxygen environment has been formed to meet the needs of long-distance transportation. The entire transport process is sealed, and the transport box is always in a low-oxygen and low-temperature state by evacuating and replacing the inert gas, which maximizes the survival rate of anaerobic bacteria.

[0027] The transport box is also suitable for the transport of other biological specimens. If hypoxic treatment is not required, there is no need to place an anaerobic culture bag in the box body 1 and perform vacuum treatment.

[0028] The temperature monitoring device 4 includes a digital temperature sensor probe 41 and an electronic temperature display screen 42 . The digital temperature sensor probe 41 is installed on the inner side of the box cover 2 , and the electronic temperature display screen 42 is installed on the outer side of the box cover 2 and is electrically connected to the digital temperature sensor probe 41 .

[0029] In this solution, the digital temperature sensor probe 41 is used to test the temperature inside the transfer box. The digital temperature sensor probe 41 will transmit the measured temperature data information to the electronic temperature display screen 42. The staff can know the temperature conditions inside the transfer box through the temperature data on the electronic temperature display screen 42. It should be noted that the temperature measurement range of the digital temperature sensor probe 41 is -50~100℃, the accuracy is ±0.5℃, and the temperature display resolution is 0.1℃.

[0030] The metal heat-conducting frame 5 is provided with a plurality of insertion holes 51 .

[0031] In this solution, the arrangement of the insertion hole 51 on the metal heat-conducting frame 5 makes it easy for the staff to insert the centrifuge tube containing the specimen into the insertion hole 51 , which is conducive to the centrifuge tube being stably located on the metal heat-conducting frame 5 .

[0032] The box body 1 and the box cover 2 both include a protective layer 11 and a heat-insulating layer 12. The heat-insulating layer 12 is fixed to the inner side of the protective layer 11. The thickness of the protective layer 11 is 5 to 15 mm, and the thickness of the heat-insulating layer 12 is 20 to 30 mm.

[0033] In this solution, the protective layer 11 is a high-strength plastic with a thickness of 5 to 15 mm, so that the box body 1 has a strong pressure resistance and can well protect the specimens in the box body 1; the insulation layer 12 is an insulation foam with a thickness of 20 to 30 mm, which can reduce the dissipation of the cold source in the box body 1 to the outside.

[0034] The metal heat-conducting frame 5 is an aluminum alloy heat-conducting frame or a stainless steel heat-conducting frame, which has a high thermal conductivity and can conduct the cold source quickly and evenly.
