Description

Transportable blood storage pack storage assembly}

The present invention relates to a transportable blood storage pack storage assembly. In more detail, the blood storage pack, which is sensitive to temperature and external shock, is not only safely stored by maintaining an appropriate temperature using a thermoelectric element, but also maintains lightness and protects against external/internal air. It relates to a storage assembly capable of efficient flow control.

Blood storage packs play an essential role in the medical field, being used to provide necessary blood to patients in a variety of situations, including emergency surgery, massive bleeding, and treatment of blood disorders.

The pack in which blood is stored is a packing material used to safely store and transport blood, and has an important function of preventing blood from being deteriorated or contaminated.

Blood has the property of being stored at an appropriate temperature and environment. Generally, whole blood is stored at a temperature between approximately 1°C and 6°C, and storage conditions may vary depending on blood components (e.g., red blood cells, platelets).

In other words, blood is only valid for a certain period of time, which entails the requirement that the temperature be kept constant during the storage period.

The use of modern transportation methods such as drones is increasing in the transportation of blood or storage packs containing blood.

Drones are especially effective when rapid transportation is needed in remote areas or in emergency situations.

The storage box for the blood storage pack used in these transportation methods must ensure temperature maintenance, shock resistance, lightness, durability, and stability.

FIG. 1 is a perspective view showing a schematic appearance of the storage assembly of the present invention, and FIG. 2 is a perspective view showing the upper cover in FIG. 1 with the open state.

First, the storage assembly of the present invention provides a structure integrated into a case and can be transported/transferred while loaded on various transportation means.

For example, it can be mounted on a drone, transported through vehicles such as emergency vehicles, helicopters, trains, ships, and airplanes, as well as carried on foot by medics in a backpack worn by medics at military units. You can.

A blood storage pack refers to a pack that stores blood classified by blood type. There is a risk of bacterial growth when exposed to room temperature for a certain period of time, so it is important not to leave it for more than 30 minutes, for example. Therefore, sensitive conditions are required to be stored while maintaining a temperature of 1 to 6°C.

In particular, in situations where the storage assembly of the present invention is exposed to the external environment, such as transportation on foot or drone during the summer when the room temperature is high, the stability of transportation and the above-mentioned temperature must be maintained. To this end, the storage assembly of the present invention must be refrigerated or In special situations such as winter when the outdoor environment is below freezing, it provides a structure that ensures the stability of the blood storage pack while providing thermal insulation.

Specifically, as can be seen from FIGS. 1 and 2, the storage assembly of the present invention is based on a case 10 that accommodates a blood storage pack, and includes first and second fans 50 and 60 and a thermoelectric element plate 30. and a heat dissipation fin (40).

The case 10 is surrounded by a plurality of standing walls 20 and a floor, has an internal space, and has an upper cover 11 rotatably mounted on an open upper surface, so that it can be opened and closed by rotating the upper cover 11. do.

This case 10 may have various three-dimensional shapes, but in the drawing, a rectangular parallelepiped structure is illustrated for convenience.

According to this rectangular parallelepiped-shaped case 10, it can be seen that it has four standing walls 20, and the adjacent standing walls 20 are arranged at an angle of 90 degrees, and each standing wall 20 has a certain area. It consists of a flat surface with

Here, the boundary portion of the two adjacent standing walls 20 has an angle of 90 degrees as described above, but this is treated with a rounding chamfer so that at least a part of the storage assembly of the present invention, especially a drone flying in the sky, is It is also possible to ensure constant speed of the drone by reducing air friction when exposed to the outside and significantly influenced by the external environment.

The floor body and top cover 11, including the standing wall 20, can be made of engineering plastics such as polycarbonate, polyethylene terephthalate, polypropylene, and acrylonitrile butadiene styrene. Specific materials among these are described below. It is explained as follows.

Polycarbonate (PC) is shock-resistant and can withstand extreme temperatures, making it a suitable material for the case 10, which functions as an external protective shell. Since it is relatively light, it can provide greater usability in drone transportation.

Polyethylene terephthalate (PET) is a lightweight material with impact resistance, heat resistance, and chemical resistance that can properly insulate and protect blood storage packs, while acrylonitrile butadiene styrene (ABS) is lighter than polycarbonate. It can provide strength and durability suitable for the case.

The upper cover 11 is rotated via a hinge to open and close the open upper surface of the case 10, and can be equipped with a separate timing device to prevent it from opening easily when closed.

As previously explained, the structure of the case 10 shown in the drawing has a rectangular parallelepiped shape, and when observed in the direction of the upper cover 11, it can be seen that the standing walls 20 are arranged up, down, left and right.

In these plurality of standing walls 20, a pair of standing walls 20 facing each other, for example, the upper and lower standing walls or the left and right standing walls, is formed with a through hole 21 roughly penetrating the central portion.

That is, in the four standing walls 20, there are a total of two pairs, one pair of upper and lower standing walls and one pair of left and right standing walls. Among these, a through hole 21 is formed in one pair of standing walls, resulting in a through hole 21. This also means that they were formed as a pair.

These through-holes 21 are for smoothly controlling the flow of air. In other words, for example, when the through-holes 21 are formed in the left and right standing walls, the left standing wall serves as the inflow of external air, and the right standing wall serves as the case. It may play a role in the outflow of air from the internal space of (10).

In this way, it is possible to have a more smooth air flow control basis by having the air inflow and outflow areas facing each other and located in a straight line.

In addition, the through hole 21 provides a spatial basis for arranging the thermoelectric element plate 30, the first and second fans 50 and 60, and the heat dissipation fin 40, which will be described later, in combination.

The thermoelectric element plate 30 has a type of plate-shaped structure arranged in parallel with the standing wall 20 where the through hole 21 is formed at a point where the through hole 21 enters the internal space of the case 10.

A thermoelectric element is a device that generates thermoelectric power by temperature difference based on power supplied from a battery. Currently known thermoelectric materials, for example, thermoelectric materials using the Seeback effect or Peltier elements (thermoelectric material) may be used, and in addition, currently known thermoelectric materials may be used.

Although not shown in the drawing, such a thermoelectric element (thermoelectric element plate in the present invention) may generally include a heating substrate, a cooling substrate, and a thermoelectric material, and the cooling surface and the heating surface are divided according to the method of controlling the power supply direction. Switching can be done reversibly.

For example, in an environment where the external temperature is higher than 1 to 6°C (generally in seasons other than winter), the side facing the center of the internal space of the case 10 becomes the cooling substrate, that is, the cooling surface, and the opposite side becomes the heating substrate, In other words, it becomes a heating surface.

In this structure, the thermoelectric element plate 30 of the present invention provides a function of absorbing heat from the inner surface (cooling surface) facing the blood storage pack and dissipating heat from the outer surface (heating surface), which is the opposite surface.

In other words, when one side of a thermoelectric element receives electricity and generates heat, the opposite side is treated as heat absorber due to the Peltier effect. Using the principle of this thermoelectric element, the cooling side adjacent to the blood storage pack functions as a heat absorber, and the opposite side absorbs heat. It is arranged to provide this heating function. Of course, in an environment where the storage assembly of the present invention is exposed to the outside in the cold winter, the power supply direction can be reversed and switched so that the side adjacent to the blood storage pack provides a heat generation function and the opposite side provides a heat absorption function.

For more specific principles and functions of thermoelectric elements, refer to known thermoelectric elements, so detailed descriptions will be omitted.

In other words, this thermoelectric element plate 30 provides a cooling function to ensure stability by maintaining a low temperature of the blood storage pack in most environments except winter, and a heat radiation fin (40) is provided on the opposite side of the blood storage pack. ) can be installed to efficiently dissipate the heat generated from the heating surface and dissipate it to the outside by driving the first and second fans (50, 60) on the air outlet side. In other words, the following description will focus on how the thermoelectric plate 30 cools (refrigerates) the blood storage pack.

The heat dissipation fin 40 is a structure installed inside and outside the through hole 21 in contact with the outer surface of the thermoelectric element plate 30.

These heat dissipation fins 40 are made of a thermally conductive material and have a structure in which a plurality of fins are arranged continuously to expand the surface area or have a large surface area. In the present invention, the heat dissipation fin 40 is a structure in which a plurality of these fins are arranged continuously. means.

These heat dissipation fins 40 are made of a material with excellent thermal conductivity, such as copper or aluminum, and are in contact with heat generation on the outer surface of the thermoelectric element, that is, in general environments except winter, thereby efficiently transferring heat generated from the thermoelectric element plate 30. It provides the function of receiving and discharging it to the outside of the case (10).

This thermal plate provides cold heat to the blood storage pack through the Peltier effect of the thermoelectric plate 30, but pursues a conduction method that absorbs heat emitted from the opposite side, so it provides better cooling and heat dissipation than the known convection structure. It has a foundation on which to build a structure.

The fan of the present invention introduces external air, cools and heats it at the thermoelectric element plate 30, and then efficiently controls the air flow to discharge the heat generated in response to the cold heat treatment to the outside. ,Includes 2 fans (50,60).

The first fan is installed in two pieces in contact with the inner surface of the thermoelectric element plate 30. More specifically, the first fan 50 is also installed on each of the standing walls 20 facing each other in which the through hole 21 is formed. Since they are installed nearby, they are formed as a pair. Accordingly, two first fans 50 per pair are installed in the internal space of the case 10, resulting in a structure in which a total of four first fans 50 are installed.

Based on this principle, it can be understood that not only the through hole 21 but also the thermoelectric element plate 30, the heat dissipation fin 40, and the first and second fans 50 and 60 all take the structure of a pair.

As mentioned earlier, in a pair of first fans 50, one (for example, the two first fans installed around the left standing wall) functions to introduce air, and the other one (in the above example, installed around the right standing wall) functions to introduce air. The two first fans) perform an air discharge function to smoothly supply and discharge external air into the internal space of the case 10.

In particular, in relation to the second fan 60, which will be described later, the first fan 50 efficiently provides cold heat from the thermoelectric element plate 30 to the blood storage pack and at the same time stores the internal space of the case 10 without any residual heat. It provides a function that allows it to be discharged quickly to the other side without remaining in the area.

To this end, it is necessary to finely control the air flow in the space inside the case than in the space outside the case, so the first fan 50 has a smaller diameter than the second fan 60, but two fans are installed adjacent to each other to ensure sufficient output. It was installed as a dog.

The second fan 60 is a single fan installed on the outer surface of the heat dissipation fin 40 with a diameter larger than that of the first fan 50, and one (for example, on the left standing wall side) supplies the external air of the case 10. Control, that is, allow external air to flow into the case, and the other (for example, on the right standing wall side) provides a function to discharge air that has passed through the heat dissipation fin 40 to the outside.

This second fan 60 is preferably manufactured with a larger diameter than the first fan 50 because the output for the inflow and smooth discharge of external air is relatively more important than the fine flow control of air than the first fan 50. do.

That is, in the present invention, a total of 6 fans are provided, that is, 2 first fans 50 and 1 second fan 60 based on the left and right standing walls, respectively, to control the smooth inflow and outflow of air. At the same time, the function of performing more efficient air flow control is provided by specializing the functions of the first and second fans (50, 60) for each area inside and outside the case (10).

According to the above-described structure, from the inner space of the case 10 to the outside, the blood storage pack - two first fans (50) - thermoelectric element plate (30) - heat dissipation fin (40) - one second fan (60) You can see that it was installed in the order of .

In summary, the storage assembly of the present invention not only provides a cold storage function to maintain the blood storage pack at a stable temperature by the thermoelectric element plate 30, but also provides a three-dimensional and Provides characteristics that perform efficient airflow control.

The power supplied to the thermoelectric plate 30 and the first and second fans 50 and 60 is stored in the battery. If the battery is placed in the inner space of the case 10, a space to accommodate the blood storage pack corresponding to the volume is created. This diminishing problem follows.

In order to provide such efficiency in space utilization, at least one of the standing walls (upper and lower standing walls based on the drawing) other than the standing wall 20 in which the through hole 21 in which the thermoelectric element plate 30, etc., is installed, is formed. It is possible for a battery storage box 70 to be installed on one of the outer surfaces.

The battery storage box 70 protrudes from the outer surface of the standing wall to have a certain volume and has a structure that can be opened and closed by rotating the cover 71.

In the standing wall to which the battery storage box 70 is attached, a through hole 21 will be formed through which the cable that supplies the power of the battery to the thermoelectric element plate 30 or the first and second fans 50 and 60 can pass. Of course it is possible.

In addition, although it was mentioned that in the rectangular case structure, the battery storage box 70 is formed on one of the two standing walls 20 other than the standing wall 20 on which the through hole 21 is formed, the storage assembly of the present invention When mounted on a drone, in order to provide structural stability while maintaining an accurate center of gravity without tilting to one side, it is more desirable to install batteries on two standing walls 20 to store batteries of similar weight.

Figure 3 is a conceptual diagram showing a structure including a temperature sensor and controller mounted on the outside of the case.

Referring to Figure 3, it can be seen that the storage assembly of the present invention includes a temperature sensor 80 and a controller 90.

The temperature sensor 80 provides the function of measuring the temperature of the interior space of the case. For this purpose, the temperature sensor 80 is mounted in the inner space of the case. Since it is necessary to measure the external temperature to check the temperature difference inside and outside the case, a temperature sensor 80 for measuring the external temperature is installed on one side of the outer surface of the standing wall 20. It is also possible to install additionally.

The temperature measured by the temperature sensor 80 is visually output to the display panel as shown in FIG. 3 so that the manager can easily check it.

The controller 90 has the function of adjusting the rotation speed of the first and second fans 50 and 60 by increasing or decreasing depending on the temperature measured by the temperature sensor 80 or the difference from the preset reference temperature. provides. In addition, the controller 90 can also differentially adjust the cooling/heating performance of the thermoelectric plate 30 by increasing the amount of current supplied.

Furthermore, the controller 90 may be equipped with a communication means to communicate with the manager (the manager's smartphone or client server) and provide information to know the situation regarding temperature control, and an application installed on the manager's smartphone may be used. It is also possible to set the rotation speed of the first and second fans 50 and 60 described above by operating the corresponding application in conjunction with the controller 90.

Through this configuration and function, the first and second fans (50, 60) can be automatically operated and the rotation speed can be differentially adjusted according to the temperature of the indoor space where the blood storage pack is stored, providing stability and convenience of storage. It is possible.

Figure 4 is a conceptual diagram showing a structure in which insulation material is packed on the inner wall of a standing wall.

As can be seen from Figure 4, it is possible for the insulation sheet 45 coated/deposited aluminum to be attached/coated to the inner surface (inner wall) of the standing wall 20.

This insulating sheet 45 can assist the cooling function of the blood storage pack by reflecting radiant heat and preventing external heat from being easily transferred to the inner space of the case.

In addition, aluminum has a high thermal conductivity, so it helps to maintain a stable temperature in the inner space of the case 10 by dispersing heat from the inner space of the case 10 to the outside with the operation of the first and second fans 50 and 60. In addition, due to its light weight, especially when the storage assembly of the present invention is mounted on a drone, it can reduce the load of the drone and provide an efficient flight environment.

In addition, the insulation sheet 45 containing aluminum serves as a kind of barrier that prevents corrosion from external moisture and oxygen and ensures a non-toxic and hygienic environment for the inner space of the case.

Figure 5 is a conceptual diagram showing a structure in which an insulation panel is coupled to a receiving groove of a standing wall.

As mentioned earlier, it was explained that the standing wall 20 can be made of engineering plastic with heat resistance, etc., and that an insulating sheet can be additionally attached, and the insulation of the standing wall 20 is further improved beyond this structural basis. There is a need to block heat exchange with the outside.

To this end, as can be seen from FIG. 5, a receiving groove 22 is additionally formed in the standing wall 20, and then a structure is provided to additionally accommodate the insulation panel 100 by inserting it into the receiving groove 22. You can.

First, the receiving groove 22 is incorporated from the top (top cover direction) to the bottom (floor body direction) with the thickness of the standing wall 20 guaranteed, and the indentation width is corresponding to the width of the standing wall 20. It means home.

That is, as can be seen from FIG. 5, the standing wall 20 takes on a structure of being recessed into a 'U' shape when viewed in the thickness direction.

An insulating panel 100 having a size corresponding to the size of the receiving groove 22 may be inserted/fitted into the receiving groove 22.

At this time, the insulation panel 100 is tightly coupled to the receiving groove 22 to prevent it from being easily separated by external shock, and the upper part of the open standing wall 20 can be sealed by covering with the upper cover 11. .

Although the insulation panel 100 is not exactly shown in the drawings (especially FIG. 6), the through hole 21 is inserted into the receiving groove 22 so as not to interfere with the operation of the above-described through hole 21 and various components installed around it. A so-called tuned through hole (not shown) is penetrated at a position and diameter corresponding to .

The insulation panel 100 may be made of a known insulation material, and may also be made of a vacuum insulation material (vacuum insulation panel) to enhance insulation performance.

Vacuum insulation has a structure in which a hollow space is created in a vacuum state and is surrounded by a metal such as aluminum or stainless steel, metallized plastic, or a multi-layer composite material.

In addition, it is possible to coat the inner wall of the material surrounding the vacuum with a thin metal film that reflects radiant heat.

This vacuum insulator provides superior insulation function compared to existing insulators, allowing the standing wall 20 to more completely block the external environment and safely store the blood storage pack contained in the inner space of the case.

FIG. 6 is a conceptual diagram illustrating a bracket connecting a standing wall to which an insulation panel is combined in FIG. 5.

In Figure 5, when the receiving groove 22 is formed in the standing wall 20, the left and right side ends of the standing wall 20 can be opened by the receiving groove 22, and in the case of the rectangular parallelepiped structure, the adjacent standing wall (receiving groove) It has an angle of 90 degrees with the formed standing wall (20), which means that unnecessary gaps may occur between the adjacent receiving grooves (22) at the boundary portion of the standing wall (20) and there may not be a proper connecting means between the standing walls (20). there is.

Therefore, a bracket that performs a joint or coupler function is provided to provide a means of connecting them and to prevent gaps.

The bracket 110 is a connecting member having a height corresponding to the height of the standing wall 20 with coupling grooves formed at both ends to detachably couple to the ends of the insulation panel 100.

That is, since two adjacent standing walls 20 are connected, two coupling grooves 111 are provided, and these two coupling grooves 111 are also arranged at an angle of 90 degrees like the standing walls 20.

In other words, the bracket 110 has a roughly 'L' structure and is made of a flexible material, that is, an elastic material, so it has elasticity and provides a function of connecting and supporting two adjacent standing walls 20.

As mentioned earlier, when the standing wall 20 is made of polycarbonate (PC), the bracket 110 can be made of a material that has better elasticity and flexibility than polycarbonate and can guarantee durability, for example. For example, it is preferably made of thermoplastic elastomer (TPE), silicone rubber, polyuteran rubber, and ethylene-propylene-diene monomer (EPDM) rubber.

At this time, a plurality of fine protrusions may be formed on the inner surface of the coupling groove 111 to prevent the end of the insulation panel 100 from being easily separated, or roughness may be provided to increase the coefficient of friction.

That is, by introducing the bracket 110 in the coupling structure of the insulation panel 100, it is possible to freely connect the standing wall 20 and provide performance capable of responding to external forces through an elastic structure.

In addition, these brackets 110 are not installed at all four corners in the rectangular case structure, but as can be seen from the drawing, the other side of the standing wall 20 connected to the bracket 110 is bent and extended to form two It can have a surface-shaped structure, and in this bent and extended structure, the bracket 110 is not needed.

At this time, the bent portion of the standing wall 20 is rounded and chamfered to provide a function of elastically resisting external force.

The composite structure of this standing wall 20 has characteristics that can simultaneously provide flexibility, mechanical durability, and convenience of combining/installing the insulation panel 100.

Since the above-mentioned bracket 110 not only connects/supports two adjacent standing walls 20 but is also exposed to the outside, it may be insufficient to firmly support them or resist external force with elasticity alone.

To this end, the surface of the bracket 110 made of silicone rubber or polyuteran rubber, especially the externally exposed surface, can be coated with an alumina composite containing alumina and a durability reinforcing layer containing a metal-organic framework. .

Alumina composite contains alumina (aluminum oxide: Al2O3) as its main ingredient, and has excellent wear resistance to resist external shocks and blows, while providing antifouling and corrosion resistance against contaminants.

In addition, alumina has a low thermal conductivity and can block external hot air from being transmitted to the interior space of the case, so it can efficiently provide an insulation function that can assist in the insulation of the standing wall 20 and the insulation panel 100. .

Metal-Organic Frameworks (MOF) are structures that create a porous structure composed of metal ions or clusters coordinated to organic ligands.

There are several types of such metal-organic frameworks, one of which is ZIF-8 (Zeolitic Imidazolate Framework-8), which has excellent compatibility with alumina.

ZIF-8 consists of zinc (Zn) ions as a metal center, and the zinc ions are connected by a 2-methylimidazole linker, an organic compound that acts as a bridge between metal ions.

At this time, the zinc ion and the 2-methylimidazole linker form a solid three-dimensional framework and form a regular and repetitive pattern to create a crystal structure.

ZIF-8's excellent porous structure, combined with the dense and rigid structure of alumina, can provide a balance of strength and porosity of the durable reinforcement layer, and adds flexibility to the structural rigidity and strength of alumina itself, thereby improving the overall mechanical stability of the durable reinforcement layer. Provides characteristics that can be improved.

In addition, ZIF-8's excellent porous structure can retain heat outside the case and reinforce the insulation function of the durability reinforcement layer.

In addition, both of these components can be manufactured through compatible processes such as sintering or powder processing, which has the advantage of convenience in manufacturing.

The durability reinforcing layer containing these can be manufactured by dispersing ZIF-8 in an organic solvent such as ethanol and then evenly dispersing and stirring the alumina composite containing alumina in the dispersed ZIF-8 solution using an ultrasonic stirrer. For example, the surface of the bracket 110 made of polyurethane rubber can be coated using an acrylic or epoxy-based binder.

Next, the final weight of the specimen was measured, and the reduced weight was measured by subtracting the final weight of the specimen from the initial weight (125 g).

2. Thermal conductivity experiment using guard-type heat flow meter equipment

Guard-type heat flow meter (Laser Flash Analysis, LFA) equipment is a device that measures the thermal conductivity of a rubber-type specimen by applying thermal shock to one side of the specimen and measuring the temperature change on the opposite side.

The specimen was cut into 1cm diameter pieces and placed in a guard-type heat flow meter, and then the temperature range of the equipment was set.

The initial temperature of the specimen was calculated, a thermal shock of 10 mJ was applied for 10 ms using a laser on one side of the equipment, and the temperature change of the specimen was measured on the opposite side.

By analyzing temperature change data, thermal conductivity was measured using thermal diffusion coefficient.

Table 1 shows the test results. Reduced weight (g) Thermal conductivity (W/mK) Example 0.21 0.21 Comparative example 0.59 0.25

As shown in Table 1 above, it can be seen that the Examples of the present invention have a lower weight reduction than the Comparative Examples and thus have excellent abrasion resistance and at the same time have low thermal conductivity and excellent thermal insulation properties.
