EXAMPLE III
Considering that the heat conductivity of the gas is poor, if the gas is simply stored in the medium storage bin 420 as a medium, the temperature control tube 200 needs to be operated in advance through the control unit, which wastes energy and brings certain inconvenience to actual operation; however, if the liquid is used as the medium, the weight of the liquid (the weight of the liquid in the medium storage tank 420 and the weight of the liquid in the liquid storage tank 650) will increase the labor intensity of the transportation of the blood sample storage device; in view of the above problems, the embodiment of the present application improves the medium storage bin 420 and the buffer bin to a certain extent on the basis of the above embodiments, and specifically includes:
the medium conveying assembly 600 comprises an air inlet passage 610, a pump body 620, a valve body 630 and a conveying pipe 640;
as shown in fig. 8 to 10, the medium storage 420 is divided into two chambers, namely a gas chamber 421 and a liquid chamber 425, for storing gas and liquid, respectively; an elastic heat conducting pipe 427 is positioned inside the gas bin 421; the elastic heat conducting pipe 427 is a rubber bag body, has a tubular main body, stores liquid therein, is used for conducting heat, is fixed on the inner wall of the temperature control pipe 200 and is tightly attached to the inner wall of the temperature control pipe 200; the gas bin 421 is communicated with the buffer bin 410 through a through hole 430; the liquid chamber 425 is communicated with the elastic heat conduction pipe 427 through a liquid conveying pipe 426; in practical use, during the process of placing the sample container, the medium storage 420 is compressed, the liquid in the medium storage is introduced into the elastic heat pipe 427 to cause the elastic heat pipe 427 to expand so as to cause the elastic heat pipe 427 to squeeze the accommodating tube 300, and the gas in the medium storage 420 is introduced into the buffer 410 to fix the sample container.
Preferably, as shown in fig. 8, the gas reservoir 421 and the liquid reservoir 425 are arranged left-to-right (gas and liquid are simultaneously forced out of the medium reservoir 420).
Preferably, as shown in fig. 9, the gas tank 421 and the liquid tank 425 are arranged one above the other (the gas and the liquid are sequentially pushed out of the medium storage tank 420).
Preferably, as shown in fig. 10, the liquid chamber 425 is a rubber bag body and is placed in the gas chamber 421;
preferably, the accommodating tube 300 is made of elastic rubber, as shown in fig. 11, after the medium storage bin 420 is compressed, the buffer bin 410 located at the upper part of the elastic heat conducting pipe 427 is expanded and encloses the accommodating tube 300 (for convenience of description, the buffer bin 410 is defined as a top air bin 422), and the expansion of the top air bin 422 plays a role of thermal insulation.
In order to promote the accommodating tube 300 to be more thoroughly sealed by the top gas bin 422, so as to obtain a better heat preservation effect and save energy, preferably, as shown in fig. 12 and 13, an annular elastic bin body is positioned on the inner wall of the top gas bin 422, the bin body is a magnetic fluid bin 424, and magnetic fluid is filled inside the bin body.
Considering that when the sample container is taken out according to the solution of the embodiment, the fingers of the person taking the sample container directly contact with the outer wall of the top air chamber 422, if the same accommodating tube 300 is used for storing the sample container (in case of untimely cleaning) for multiple times, cross contamination may be caused (bacteria on the gloves adhere to the accommodating tube 300, and may adhere to one or more sample containers placed in the accommodating tube); preferably, the blood sample storage device further comprises a push assist assembly 700; as shown in fig. 14, the push assistance assembly 700 includes a ring magnet 710, a support ring 720, and a hand lever 730; the annular magnet 710 is fixed on the support ring, the diameter of the annular magnet 710 is larger than or equal to that of the positioning hole 110, and the handheld rod 730 is a rod body and is fixed on the support ring 720 for facilitating handheld; before taking the sample container, the annular magnet 710 is placed on the positioning hole 110, so that the magnetic fluid bin 424 is influenced by magnetic force to drive the top air bin 422 to deform, and the sample container is exposed; cleaning or replacing the hand-held wand 730 is more convenient than cleaning the containment tube 300.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
