Description

Technical Field

[0001] The utility model relates to the technical field of transport boxes, in particular to a constant temperature specimen transport device. Background Art

[0002] Specimen transport equipment is a type of equipment used to transport biological samples or medicines. It usually keeps the samples stable within a certain temperature range under specific temperature conditions, and uses an insulated box to achieve the function of transportation. Existing specimen transport boxes usually use insulation materials such as aluminum film to control the temperature. If low-temperature storage is required, ice packs are placed to achieve a short-term constant temperature effect. The advantages of this insulated box are low cost, good effect, and sufficient cost-effectiveness.

[0003] However, when transporting biological samples such as specimens and blood, the temperature control requirements in the transport equipment are high, otherwise they may lose their activity or effectiveness due to temperature fluctuations. In addition, the air flow in the box is poor, which may cause the formation of local hot spots or cold spots due to uneven temperature distribution, thus affecting the preservation conditions of individual biological samples. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a constant temperature specimen transportation device.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A constant temperature specimen transport device comprises a box body and a box cover, wherein a sample fixing area and an air supply area are arranged in the box body, the sample fixing area and the air supply area are connected, a plurality of test tube slots are arranged in a matrix in the sample fixing area, a clamping part and a shock absorbing part are arranged in the test tube slot, the clamping part and the shock absorbing part are respectively arranged on the side wall and the bottom of the test tube slot, a temperature control mechanism and an air supply mechanism are arranged in the box cover, the air supply mechanism is connected with the air supply area through an air guide pipe, and the box cover is buckled and connected with the box body.

[0007] Further, the inner wall of the test tube slot is symmetrically provided with mounting slots, and the mounting slots are provided with clamping parts, and the clamping parts include an elastic rotating part and a clamping plate, and the elastic rotating part is rotatably connected to the clamping plate through a connecting rod. The mounting slot is used to accommodate the elastic rotating part and the clamping plate, and the elastic rotating part includes a shell and a torsion spring, and the torsion spring is arranged in the shell, and the connecting rod is rotatably connected to the shell through a rotating shaft, and the rotating shaft passes through the torsion spring. When in use, the test tube is against the clamping plate, the connecting rod rotates downward, and the torsion spring rotates and compresses. At this time, the two clamping parts can clamp test tubes of different sizes between them, and can also be tightly fixed under the action of the torsion spring. When the box body is subjected to a lateral force, the elasticity of the elastic rotating part can also reduce the impact force on the test tube. The elastic rotating part is arranged in the mounting slot and will not occupy the inner wall space of the test tube slot. And when a test tube with a diameter slightly smaller than the diameter of the test tube slot is inserted, the clamping plate can be squeezed into the mounting slot, and at the same time, an elastic fixing effect can be achieved.

[0008] Furthermore, an arc guide plate is provided at the upper end of the clamping plate, and the concave surface of the arc guide plate faces the central axis of the test tube slot. When inserting the test tube downward, the arc guide plate can guide the test tube to the center of the test tube slot to avoid being blocked during the insertion process. The clamping plate is also designed with an arc surface structure, which can achieve a more fitting clamping effect according to the clamped test tube.

[0009] Furthermore, the shock absorbing part includes a bottom bracket and a shock absorbing spring. The top surface of the bottom bracket is a concave arc structure. The bottom bracket is fixed to the bottom of the test tube slot by two symmetrically arranged shock absorbing springs. The shock absorbing spring can ensure that the box body will not cause a large impact force and vibration to the test tube when subjected to a longitudinal impact force. The two shock absorbing springs can maintain balance and stability in the horizontal direction.

[0010] Furthermore, the temperature control mechanism includes a compressor and a control panel, wherein the compressor is arranged in the inner cavity of the box cover, and the control panel is arranged on the top surface of the box cover and connected to the control panel. The temperature can be monitored and adjusted in real time through the temperature display and key operation of the control panel.

[0011] Furthermore, several of the test tube slots are connected to each other, and an air guide slot leading to the sample fixing area is provided in the air supply area. The lower ends of the test tube slots are connected, and under the action of the air guide slots, the wind delivered from the outside can be evenly guided to each test tube slot, thereby improving the air flow in the box, making the temperature distribution uniform, and not causing the formation of local hot spots or cold spots, thereby ensuring the preservation conditions of biological samples.

[0012] Furthermore, the air supply mechanism includes a micro fan connected to the air guide pipe, the air guide pipe is extended downward and can be plugged into the air guide groove, and the box cover is also provided with an exhaust port. Under the action of the micro fan, the air guide pipe guides the refrigeration gas of the compressor into the air guide groove, and is connected to the sample fixing area through the air guide groove, so as to achieve a suitable temperature preservation condition. When the micro fan is working, the exhaust port can perform the functions of heat dissipation and ventilation. A switch for controlling the micro fan is also provided on the box cover, and the air supply function is controlled by turning it on or off.

[0013] Furthermore, a handle is provided on the top of the box cover, and the box body and the box cover are provided with locks that cooperate with each other. The handle is convenient for hand-carrying operation, and the lock can fix the box body and the box cover. When it is necessary to open, the limiting mechanism on the lock can be pressed to open it.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model can improve the anti-vibration effect of the sample when it is moved by arranging a clamping part and a shock absorbing part in the test tube slot, thereby ensuring that the sample container will not be damaged due to vibration or impact during transportation. In addition, considering the sizes of different sample test tubes, it can also provide flexibility and applicability;

[0016] 2. The utility model can monitor the temperature inside the box and maintain a constant temperature by adjusting the refrigeration temperature, which helps to ensure that the biological samples can remain stable under the required temperature conditions throughout the transportation process, thereby preventing them from losing activity or effectiveness due to temperature fluctuations;

[0017] 3. The utility model helps to maintain air flow inside the constant temperature specimen transport device, maintains a uniform temperature inside the entire box through air flow, and avoids the formation of local hot spots or cold spots that may cause temperature instability or adversely affect individual biological samples.
