Description

Technical Field

[0001] The present invention relates to a medical transport box, in particular to an epidemic prevention and isolation transport box. Background Art

[0002] The current healthcare model suffers from resource waste because specimens cannot be shared across different medical institutions, leading to duplicate testing, wasted medical resources, and increased patient burden. Strict and effective specimen transportation is an effective measure to reduce duplicate testing. Therefore, ensuring the safe and reliable transportation of specimens is crucial for optimizing the healthcare model.

[0003] Chinese invention patent application number 201310751354.5 discloses an IoT-based intelligent medical specimen transport box. A partition panel is fixedly installed within the box, dividing the box into a left and right space. The left space houses cooling equipment, while the right space houses a specimen holder. The partition panel is equipped with a heat-absorbing hole equipped with an opening control valve. Pressure sensors, humidity sensors, temperature sensors, a control host, and actuators are also installed on the inner wall of the transport box. A GPS locator and wireless antenna are also installed on the outer surface of the transport box. This system ensures the safe and reliable transport of specimens to their destination. Furthermore, it enables real-time remote monitoring of environmental parameters within the box during transport, ensuring the safe transport of specimens.

[0004] The Chinese invention patent application with application number 202010165568.4 discloses a microbial specimen transfer box, comprising a transfer box body and a box lid that seals the transfer box body. The box lid and the transfer box body are connected by a hinge shaft. A placement rack for placing specimen containers is provided in the transfer box body; a central processing unit, a temperature control device, a temperature sensor, an alarm device, and a power supply device are also provided; and a display and control device is provided on the box lid. The placement holes on the placement rack are used to place specimen containers. The placement racks are separated from each other by flat plates above and below, and separated and fixed by partitions on the left and right. It adopts a temperature control device and monitors and feedbacks the temperature in real time to achieve effective temperature control and temperature regulation. The fixed structure of the placement rack in the transfer box is compact, the placement rack is highly stable, and the specimen container is better protected. It realizes intelligent remote monitoring and viewing of data in the transfer box, making it more convenient to use and providing a better user experience.

[0005] Overall, the existing technology rarely considers the protection of the stability of the specimen container by the structure inside the box. The specimen transportation specifications require that specimens be sent for inspection at the specified time and temperature and cannot be shaken violently. Manually picking up the transport box is an essential step in the process of transporting inspection specimens. During manual transportation, the transport box will naturally swing with the operator's hand movements, which will inevitably cause the center of gravity of the transport box to shift, causing the specimens inside the transport box to shake more. To avoid this phenomenon, the operator can only rely on gentle handling, which is too demanding for the operator. Secondly, the center of gravity design of the medical transport box in the existing technology is based on a full load state. When the specimen tubes are not full of the box, the center of gravity will inevitably shift, increasing the shaking amplitude. In addition, the existing technology's research on inspection specimen transport boxes focuses more on temperature control and real-time monitoring, but the location of the temperature sensor is mostly set on the box wall, which makes it difficult to avoid the disadvantage of inaccurate temperature control caused by uneven temperature distribution inside the box. Therefore, the medical transport box in the existing technology is not suitable for strict, effective, and high-precision inspection specimen transportation requirements. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of the present invention is not limited to the following embodiments, and any form of modification and / or change made to the present invention will fall within the scope of protection of the present invention.

[0029] In the present invention, unless otherwise specified, all parts and percentages are by weight. The equipment and raw materials used are commercially available or commonly used in the art. The methods in the following embodiments, unless otherwise specified, are conventional methods in the art. The components or equipment in the following embodiments, unless otherwise specified, are all universal standard parts or components known to those skilled in the art. Their structures and principles are known to those skilled in the art through technical manuals or routine experimental methods.

[0030] Example 1:

[0031] like Figure 1 The shown example is an epidemic prevention and isolation transport box, comprising a box body 1 and a box lid 2, which are movably connected to each other. A specimen fixing device 3, a center of gravity adjustment device 4 and a center of gravity detection device 5 are provided in the box body. The center of gravity detection device is provided on the specimen fixing device, and the specimen fixing device is fixed to the inner wall of the box body through the center of gravity adjustment device. The center of gravity adjustment device is used to adjust the center of gravity of the specimen fixing device according to the detection result of the center of gravity detection device. A power supply device 10 and a control device 11 are provided in the box lid, and the power supply device, the center of gravity adjustment device and the center of gravity detection device are all electrically connected to the control device.

[0032] Through the above technical solution, when the specimen fixing device is not fully loaded with specimen test tubes and the center of gravity of the entire box shifts due to uneven weight distribution, or when the center of gravity shifts due to the force exerted by the operator's arm swing when lifting the box for transportation, the center of gravity detection device detects the center of gravity shift state and transmits the center of gravity shift data to the control device. The control device adjusts the force applied to the specimen fixing device through the center of gravity adjustment device according to the center of gravity shift data, so that the center of gravity of the specimen fixing device shifts to the initial point, thereby greatly reducing the shaking amplitude of the specimen test tubes fixed by the specimen fixing device and avoiding violent shaking of the specimen.

[0033] Example 2:

[0034] like Figure 1 The illustrated quarantine and transportation box includes a box body 1 and a box lid 2, which are movably connected by a hinge. The box body and the box lid are equipped with a specimen fixture 3, a center of gravity adjustment device 4, a center of gravity detection device 5, a cooling device 6, and a main cooling air duct 7. The specimen fixture is fixed to the inner wall of the box via the center of gravity adjustment device. The center of gravity adjustment device is used to adjust the center of gravity of the specimen fixture according to the detection result of the center of gravity detection device. The cooling device is located at the bottom of the box body. The main cooling air duct is located between the specimen fixture and the inner wall of the box body. A secondary cooling air duct 8 is provided within the specimen fixture, extending through the specimen fixture. A hole 9 is provided in the middle of the specimen fixture, opening toward the box lid. The center of gravity detection device is located at the bottom of the hole. The main cooling air duct is connected to the hole through the secondary cooling air duct. The box lid is equipped with a power supply 10, a control device 11, and a temperature sensor 12. The temperature sensor is located at the center of the bottom of the box lid. When the box lid and the box body are closed, the temperature sensor is located in the hole of the box body. A handle 14 is provided on the top of the box lid. The power supply device, the temperature sensor, the center of gravity adjustment device, the center of gravity detection device and the temperature reduction device are all electrically connected to the control device.

[0035] The specimen fixing device includes a shell 301 and a specimen fixing body 302. The specimen fixing body is detachably fixed to the shell. The specimen fixing body is a cylinder. A plurality of evenly distributed specimen fixing holes 303 are provided on the specimen fixing body. Evenly distributed secondary cooling air ducts are provided between the specimen fixing holes. The secondary cooling air ducts are distributed in a circular array in the cylinder with the cylinder axis as the center. For better cooling effect, multiple layers of secondary cooling air ducts can be provided along the axial direction of the cylinder. In this embodiment, only one layer is provided. Specimen fixing holes are evenly distributed between adjacent secondary cooling air ducts. From the cross section of the cylinder, as shown in FIG. Figure 2 As shown, the distribution area of ​​the specimen fixing holes is evenly divided into six sector-shaped areas by the secondary cooling air duct, and the specimen fixing holes are perpendicular to the direction of the secondary cooling air duct.

[0036] There are multiple center of gravity adjustment devices evenly distributed on the surface of the specimen fixing device. One end of the center of gravity adjustment device is fixed to the specimen fixing device, and the other end of the center of gravity adjustment device is fixed to the inner wall of the box. Figure 3As shown, each center of gravity adjustment device includes a compression spring 401 and an electric push rod 402 arranged in parallel, the two ends of the compression spring are respectively connected to the inner wall of the box and the specimen fixing device, the non-working end of the electric push rod is fixed to the inner wall of the box, and the working end of the electric push rod is fixed to the specimen fixing device. The electric push rod is electrically connected to the control device.

[0037] Multiple center-of-gravity adjustment devices are evenly distributed on the top and bottom end surfaces of the specimen fixture. The center-of-gravity adjustment device located on the top end surface of the specimen fixture is horizontally arranged, while the center-of-gravity adjustment device located on the bottom end surface of the specimen fixture is arranged at an angle to the horizontal plane. The center-of-gravity adjustment devices located on the top end surface of the specimen fixture are staggered with the center-of-gravity adjustment devices located on the bottom end surface of the specimen fixture. In this embodiment, three center-of-gravity adjustment devices are located on the top end surface of the specimen fixture, and three center-of-gravity adjustment devices are located on the bottom end surface of the specimen fixture. From a cross-section of the cylinder, adjacent center-of-gravity adjustment devices are spaced 60° apart with respect to the cylinder axis. The center-of-gravity adjustment device located on the bottom end surface of the specimen fixture is angled 30° to the horizontal plane. The thrust of each electric push rod is individually controlled by a control device, thereby enabling fine-tuning of the specimen fixture at any angle along the X, Y, and Z axes. The compression spring is initially in a compressed state, so that the specimen fixture will not be affected by slight shaking forces and cause position displacement in the normal state. When the electric push rod applies thrust, the compression spring is stretched to generate a resistance opposite to the thrust, which is used to buffer the thrust of the electric push rod on the specimen fixture, making the position and angle adjustment of the specimen fixture smoother.

[0038] like Figure 4 As shown, the center of gravity detection device includes a detection housing 501, a central body 502, a fixed spring 503, and a position sensor 504. The central body is located at the center of the detection housing and is connected to the inner wall of the detection housing via a number of fixed springs. In this embodiment, the central body is a cube, and fixed springs are set on the six sides of the cube to connect to the inner wall of the detection housing. The elastic force of each fixed spring is exactly the same. The position sensor is located in the detection housing and is used to detect the position of the central body. The position sensor is electrically connected to the control device. By calculating the weight of the entire quarantine and isolation transport box and adjusting the counterweight inside the box, the center of gravity of the entire box is aligned with the position of the central body. When the center of gravity of the entire box changes under the influence of external forces, the position of the cube deviates from its initial position. The position sensor detects this position change and transmits data to the control device. The control device controls the thrust of each electric push rod based on this data to adjust the position of the specimen fixing device, thereby returning the central body in the center of gravity detection device to its initial position. By setting a suitable algorithm, the influence of the elastic force of the fixed springs on the change of the central body position can be filtered out, but this does not fall within the scope of protection claimed in the present invention and is therefore not described in detail.

[0039] The cooling device is a hollow structure, and speed-controlled fans 601 are provided at both ends of the cooling device. The hollow structure of the cooling device is used to place a cold source, which can be ice or other refrigerants, and the speed-controlled fans are used to guide the cold air into the main cooling air duct.

[0040] The lid is provided with a recessed cavity 201 at the junction with the body. When the lid and body are closed, the recessed cavity cooperates with the top of the specimen fixture to form a top cooling duct 13 that communicates with the main cooling duct. The recessed cavity also serves to provide space for the heads of specimen tubes when they are placed.

[0041] The box body is also provided with a counterweight 101. The counterweight is used to facilitate the adjustment of the initial center of gravity of the entire quarantine transport box so that the center of gravity of the entire box coincides with the center of gravity detection device.

[0042] Example 3:

[0043] An epidemic prevention and isolation transport box, the technical solution is the same as that of Example 2, except that:

[0044] like Figure 5 As shown, the center of gravity detection device includes a detection housing 501, a center body 502, and a pressure sensor 505. The center body is a cube, and the pressure sensors are located on the five surfaces of the cube except the top surface. The pressure sensors are electrically connected to the control device. By calculating the weight of the entire quarantine transport box and adjusting the counterweight inside the box, the center of gravity of the entire box is aligned with the position of the center body. When the center of gravity of the entire box changes under the influence of external forces, the pressure sensor detects the pressure change on the surface of the cube and transmits the data to the control device. The control device controls the thrust of each electric push rod based on this data to offset the pressure change on the center body, thereby restoring the pressure on the center body to balance.

[0045] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solution described in the claims.
