Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blood specimen storage and transportation technology, specifically, it relates to a blood specimen transport box. Background Technology
[0002] In the clinical treatment of patients with mental illness, regular monitoring of blood drug concentrations is a crucial step, as it is decisive for assessing medication adherence and disease progression. For example, patients with mental illness must strictly adhere to their doctor's orders to take medication on time and in the prescribed dosage. To accurately understand the patient's medication adherence and disease status, hospitals typically need to frequently draw blood for testing and analyze blood drug concentrations to make judgments.
[0003] Given that these patients require frequent blood tests (e.g., multiple times per week), hospitals commonly use blood sample transport boxes with ice trays for sample transport. However, existing transport boxes face some challenges in practical use:
[0004] The rapid melting of ice cube trays has become a significant issue due to the frequent opening and closing of the transport box for storing and retrieving blood samples. Current solutions involve frequently replacing the ice cube trays to maintain the required low temperature inside the transport box. However, this approach doesn't fundamentally solve the problem because the ice cubes enter a solid-liquid mixture during melting. This increased surface area between the ice and liquid, intensifying heat transfer and causing the ice to absorb heat and melt more quickly.
[0005] Furthermore, while frequent replacement of the ice tray can maintain the low temperature to some extent, it does not slow down the melting rate of the ice tray, nor does it substantially extend the duration of the low temperature. More importantly, during the process of replacing the ice tray, the transport box needs to be opened, allowing outside air to easily enter. This can not only cause the temperature of the blood sample to rise, but also adversely affect the preservation quality of the blood sample, thereby impacting subsequent testing and analysis.
[0006] In addition, many patients with mental illnesses conceal their condition, and some even steal blood samples from transport boxes to interfere with hospital testing. Utility Model Content
[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a blood specimen transport box.
[0008] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:
[0009] A storage rack, wherein the storage rack has a space for holding blood sample tubes, and the storage rack is made of a thermally conductive material;
[0010] In this invention, the storage rack is made of stainless steel, which has good heat transfer capacity. The storage space consists of multiple test tube storage slots on the stainless steel frame. The top of the stainless steel frame and the inside of the test tube storage slots are covered with nylon cloth and EPP plastic foam. The nylon cloth and EPP plastic foam are laminated together to form a layer covering the storage rack, which can achieve the effect of heat preservation. The bottom of the storage rack is bare stainless steel, which is used to conduct the cold air emitted by the ice cubes.
[0011] The low-temperature channel is used to hold ice blocks, which are placed below the storage rack. The low-temperature channel has a slope, and the storage rack and the low-temperature channel together restrict the movement of the ice blocks. The low-temperature channel has an outlet, and one side of the low-temperature channel is provided with an insulated space for holding liquid water. When part of the ice blocks melts into liquid water, the liquid water flows from the outlet into the insulated space along the slope. The low-temperature channel also has an inlet for replenishing ice blocks into the low-temperature channel.
[0012] In this invention, when the ice melts into liquid water, it flows from the outlet into the insulated space along the sloping surface, thereby achieving solid-liquid separation and avoiding solid-liquid mixing. This extends the storage time of the ice and prolongs the low-temperature maintenance time of the blood sample transport box. Compared with the prior art, there is no need to frequently replace the ice tray, reducing the contact between external air and the blood sample inside the box, improving the storage quality of the blood sample, and facilitating subsequent testing.
[0013] Preferably, the cross-sectional area of the inlet is larger than the cross-sectional area of the outlet.
[0014] In this invention, the cross-sectional area of the inlet of the cryogenic channel gradually decreases towards the outlet to accommodate the volume changes as the ice gradually melts. This ensures that the ice has a fixed size at each stage of melting, allowing it to remain in the cryogenic channel for an extended period while melting. The cold air emitted by the ice itself helps maintain the low-temperature environment inside the blood sample transport box. Furthermore, the solid-liquid separation process reduces heat transfer from the ice, slowing down the melting rate.
[0015] Preferably, it also includes a supplementary channel, which contains ice blocks, and an ice-feeding plate for supporting the ice blocks is rotatably connected inside the supplementary channel, the ice-feeding plate being rotatably attached to the inlet;
[0016] In this invention, when the ice delivery plate is in a horizontal state, it can support the ice blocks stacked in the replenishment channel. When the ice delivery plate rotates and rests against the inlet, the ice blocks at the bottom of the stack can slide into the inlet under the action of gravity, thereby replenishing the low-temperature channel with ice blocks and further extending the time of maintaining the low-temperature environment inside the blood specimen transport box.
[0017] A drive unit is provided on one side of the supplementary channel, which is used to drive the ice delivery plate to rotate.
[0018] Preferably, the low-temperature channel has multiple moving channels for separating and moving ice blocks, and the supplementary channel has multiple delivery channels adapted to the moving channels, so that ice blocks can enter the moving channels through the delivery channels;
[0019] In this invention, by setting multiple moving channels, the movement path of the ice cubes is fixed and the degree of freedom of the ice cubes is restricted, so that they can only move on the moving path. This avoids the situation where ice cubes of the same volume stick together due to irregular movement in the low temperature channel.
[0020] Preferably, the width of the moving channel is equal to that of the delivery channel.
[0021] In this invention, by limiting the width of the moving channel to be equal to that of the delivery channel, ice blocks in the delivery channel can smoothly enter the moving channel.
[0022] Preferably, the storage rack has multiple heat-insulating channels, which are connected to the low-temperature channels, so that the cold air inside the low-temperature channels can enter the heat-insulating channels.
[0023] In this invention, by setting up multiple heat-insulating channels to accommodate cold air, it helps to form a low-temperature environment inside the storage rack and improves the temperature control effect, which is beneficial for the storage of blood samples.
[0024] Preferably, the supplementary channel has a co-liquid space, and two co-liquid channels are provided on one side of the co-liquid space. The co-liquid space is connected to the heat preservation space through the two co-liquid channels.
[0025] In this invention, when too much liquid water is stored in the insulation space, it will be distributed into the common liquid space through the common liquid channel. By storing liquid water in the insulation space, the common liquid channel, and the common liquid space, an insulation layer is formed at the bottom of the blood specimen transport box, reducing heat transfer from the bottom of the blood specimen transport box and further improving the insulation effect inside the blood specimen transport box.
[0026] Preferably, the ice block is a cube, and the width of the ice block is smaller than the width of the moving channel.
[0027] In this invention, when the ice blocks are cubes, the stacking of the ice blocks is more stable. When the blood sample transport box is subjected to external force, the shaking frequency inside the replenishment channel will be reduced, thereby reducing the damage caused by shaking of the cube ice blocks and the replenishment channel.
[0028] Preferably, the ice block is a sphere, and the diameter of the ice block is smaller than the width of the moving channel.
[0029] In this invention, when the ice block is spherical, after the ice delivery plate rotates and rests against the inlet, the spherical ice block easily rolls into the inlet and enters the low-temperature channel, making the movement of the ice block smoother.
[0030] Preferably, it also includes a box body, the storage rack is disposed inside the box body, a connecting cover is rotatably connected to one side of the box body, a spring plate is connected to one side of the connecting cover, and a locking groove is provided inside for the spring plate to be inserted and locked.
[0031] Preferably, the elastic plate has a lock head, and the lock groove has a lock opening adapted to the lock head.
[0032] Compared with the prior art, the advantages of this utility model include:
[0033] (1) The blood specimen transport box provided by this utility model has a simple structure, does not require manual replenishment of ice to the low temperature channel, and is easy to maintain;
[0034] (2) The blood specimen transport box provided by this utility model, when the ice melts into liquid water, will flow into the heat preservation space from the outlet along the sloping surface, thereby achieving solid-liquid separation, avoiding the occurrence of solid-liquid mixing, and thus extending the storage time of the ice, thereby extending the low temperature maintenance time of the blood specimen transport box. Compared with the prior art, there is no need to frequently replace the ice tray, reducing the contact between the external air and the blood specimen inside the box, improving the storage quality of the blood specimen, and helping subsequent testing;
[0035] (3) The blood specimen transport box provided by this utility model has an ice delivery plate that can support ice blocks stacked in the replenishment channel when the ice delivery plate is in a horizontal state. When the ice delivery plate is rotated and leans against the entrance, the ice blocks at the bottom of the stack can slide into the entrance under the action of gravity, thereby replenishing ice blocks to the low temperature channel and further extending the low temperature environment maintenance time inside the blood specimen transport box.
[0036] (4) The blood sample transport box provided by this utility model can be closed and locked by inserting the lock head of the elastic plate into the lock slot. The hidden lock structure can hinder the behavior of mental patients to touch and open the blood sample transport box, reduce the occurrence of blood sample theft, and help the hospital's testing.

[0050] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.
[0051] Example 1
[0052] Please see Figure 1 , Figure 4 and Figure 6 A blood specimen transport box, including the transport box.
[0053] Specifically, the transport box includes a box body 11, and a connecting cover 13 is rotatably connected to one side of the box body 11. The connecting cover 13 is provided with a locking structure, and the connecting cover 13 is locked to the box body 11 through the locking structure, thereby closing the transport box.
[0054] Specifically, the locking structure includes an elastic plate 15 fixedly connected to the connecting cover 13. The elastic plate 15 is elastic, specifically thermoplastic polyurethane, and can deform to a certain extent. A lock head 16 is integrally formed at the end of the elastic plate 15. A lock groove 14 is opened on the top of the box body 11 for the elastic plate 15 to be rotated and inserted into. A lock opening is opened in the lock groove 14.
[0055] In this embodiment, when the connecting cover 13 rotates and covers the housing 11, the lock head 16 will first press against the lock groove 14, causing the elastic plate 15 to deform, thereby allowing the lock head 16 to insert into the lock groove 14 and move into the lock opening. Since the housing 11 is made of plastic, when it is necessary to open the connecting cover 13, it is only necessary to press the lock opening from the outside of the housing 11 to apply force to rotate the connecting cover 13, so that the lock head 16 can be pulled out from the lock opening, and the connecting cover 13 can be opened.
[0056] Please see Figure 1 , Figure 2 and Figure 3 A blood specimen transport box, including a storage rack 12.
[0057] Specifically, the top of the storage rack 12 is flat, the bottom of the storage rack 12 has a slope, and the top of the storage rack 12 is provided with a receiving space 2. The receiving space 2 is specifically 16 test tube storage slots opened in the storage rack 12, so that test tubes carrying patient blood samples can be inserted into the test tube storage slots from the top of the storage rack 12 for storage.
[0058] Specifically, the storage rack 12 has 6 heat preservation channels 36. A heat preservation channel 36 is set in the middle area between every 4 test tube storage slots so that the cold air from the ice cubes can be evenly transferred to the surrounding test tube storage slots after entering the heat preservation channel 36.
[0059] Please see Figure 2 , Figure 3 and Figure 5 A blood specimen transport box, including a cryogenic passage 3.
[0060] Specifically, five partitions 37 are fixedly connected to the top of the low-temperature channel 3. The partitions 37 and the low-temperature channel 3 form five moving channels 31, so that the ice blocks can move along five different paths. The moving channels 31 have a slope, and the sloped surface and the inclined surface at the bottom of the storage rack 12 form the moving channel 31 for the ice blocks. The two ends form an inlet and an outlet. The cross-sectional area of the outlet is smaller than that of the inlet, so that after the ice blocks enter the moving channels 31, the slow melting of the ice blocks will have space corresponding to their melted volume to restrict the ice blocks, thereby restricting the position of the ice blocks and preventing the ice blocks from sliding directly down the sloped surface to the outside of the low-temperature channel 3.
[0061] Specifically, each moving channel 31 is provided with three drainage channels 38. Through the setting of drainage channels 38, the moving channel 31 can be discharged through other paths, further reducing the contact between ice and liquid water and slowing down the melting rate of ice.
[0062] Specifically, the blood specimen transport box has an insulated space 33 inside, which is close to the outlet. Liquid water flowing out of the moving channel 31 is discharged into the insulated space 33 for storage. The blood specimen transport box also has a common liquid space 34 inside, with two common liquid channels 32 on one side. The common liquid space 34 is connected to the insulated space 33 through the two common liquid channels 32.
[0063] In this embodiment, when the liquid water level inside the insulation space 33 exceeds the common liquid channel 32, the liquid water will flow into the insulation space 33 and form an insulation layer at the bottom of the blood specimen transport box to block the transfer of heat.
[0064] In this embodiment, drainage holes are provided in both the heat preservation space 33 and the co-liquid space 34. A leather plug 35 is inserted into the drainage hole. When the blood sample is taken out of the transport box, the liquid water inside the transport box can be drained by removing the leather plug 35.
[0065] Please see Figure 2 , Figure 3 and Figure 5 A blood sample transport box, including a replenishment channel 4.
[0066] Specifically, the replenishment channel 4 is located inside the housing 11, and four partition plates 41 are fixedly connected inside the replenishment channel 4. The four partition plates 41 divide the replenishment channel 4 into delivery channels 42, which correspond one-to-one with the positions of the moving channel 31. Each delivery channel 42 can store ice blocks. Below each delivery channel 42, near the entrance of the low-temperature channel 3, an ice delivery plate 54 is rotatably connected. Inside the housing 11, on one side of the replenishment channel 4, a driving component 5 is provided, which can drive the ice delivery plate 54 to rotate.
[0067] In this embodiment, when the driving member 5 drives the ice-feeding plate 54 to rotate to a horizontal state, ice blocks can be stored using the delivery channel 42. When the driving member 5 drives the ice-feeding plate 54 to rotate to a state where it is against the inlet, the ice plate 54 is tilted, and the ice blocks can slide off the ice plate 54 to the inlet by their own weight, thus replenishing the low-temperature channel with ice blocks.
[0068] In this embodiment, the drive unit 5 is powered externally, and a time relay is installed inside the housing 11 to set the time interval for the drive unit 5 to start and replenish ice blocks into the low-temperature channel 3 at regular intervals. In other embodiments, the drive unit 5 is powered by a mobile power supply added inside the housing 11.
[0069] Specifically, the drive component 5 includes a mounting slot opened in the housing 11. A dual-head servo motor 51 is fixedly connected in the mounting slot. Both drive ends of the dual-head servo motor 51 are fixedly connected to drive rods 55. One end of the drive rod 55 is fixedly connected to a rope winding roller 52. A traction rope 53 is wound and connected in the rope winding roller 52. The traction rope 53 is fixedly connected to the ice delivery plate 54 for attaching to the side of the entrance.
[0070] It is understandable that the exterior of the enclosure 11 may also be equipped with a display module for displaying temperature data. This display module has a temperature sensor that is connected to the interior of the enclosure 11 to monitor the temperature inside the enclosure 11 and display it on the display module so that the user can read the temperature from the outside.
[0071] In this embodiment, the specific steps for replenishing ice from replenishment channel 4 to low-temperature channel 3 are as follows:
[0072] First, the dual-head servo motor 51 is started to rotate the drive rod 55, causing the rope roller 52 to rotate and release the traction rope 53. This allows the ice delivery plate 54 to rotate under its own weight and rest against the entrance. At this time, the dual-head servo motor 51 is turned off, and the ice blocks stored on the ice delivery plate 54 slide off the ice delivery plate 54 under its own weight into the entrance. The ice blocks that are in the delivery channel 42 will be blocked by the ice blocks that have just been delivered and cannot be moved out. At this time, the dual-head servo motor 51 is started again, causing the drive rod 55 to drive the rope roller 52 to rotate and wind up the traction rope 53. The traction rope 53 pulls the ice delivery plate 54 to rotate and reset, thus completing the delivery of ice blocks into the low-temperature channel 3.
[0073] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
