Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a portable wind-heated blood incubator. Background Technology

[0002] The following needs exist in the current medical scenario: Due to the scarcity of blood components and the potential adverse reactions to transfusion, blood components are only used for emergency treatment rather than routine treatment in clinical practice. Therefore, when clinical departments or operating rooms need to transfuse blood components, they must urgently obtain blood from the blood transfusion department. Red blood cells are refrigerated (4°C) and taken directly, plasma and cryoprecipitate clotting factors are frozen (below -20°C) and taken after being thawed by a plasma thawer, and platelets are stored (20°C) and taken directly. After clinical blood collection, it cannot be left to stand and must be transfused immediately and rapidly. During the transfusion process (especially when transfusing large amounts of red blood cells), massive transfusion complications often occur, such as hypothermia, which can cause acidosis, coagulation dysfunction, DIC, shock, and even death in patients.

[0003] The blood rewarming devices used in the current technology have a simple structure and a short rewarming time (only a few seconds), which cannot guarantee the rewarming of blood during rapid transfusion. If the transfusion is slow, the patient may be in danger due to massive blood loss.

[0004] Therefore, there is a need for a device that can perform rewarming during the transport of blood components, thereby increasing the rewarming time of blood components and solving the problems of the aforementioned blood rewarming device. Utility Model Content

[0044] Box 1, wherein an interlayer is provided between the inner wall and the outer wall of the box 1, and a partition 101 is provided in the interlayer, the partition 101 dividing the interlayer into a heating section and a blowing section;

[0045] Heating component 2, which is located inside the heating section;

[0046] Blower assembly 3, which is located inside the blower section;

[0047] The air inlet of the heating section is connected to the air outlet of the blower section. The air outlet of the heating section is located at the end of the housing 1 away from the blower section. The air inlet of the blower section is located on the side wall of the housing 1 corresponding to the blower assembly 3.

[0048] Air enters the heating section through the air inlet of the blower and flows into the heating section under the action of the blower assembly 3. The air is heated by the heating assembly 2 and the temperature is transferred to the inner wall of the box 1, thereby heating the inside of the box 1. Then the air flows out through the air outlet of the heating section.

[0049] The heating component 2 is a nickel-chromium heating wire, and the blower component 3 is an axial fan.

[0050] In some embodiments, a temperature sensor is installed inside the chamber, and a controller is fixed on the outside of the chamber. The controller is used to adjust the power of the heating component to adjust the temperature inside the chamber, and the temperature sensor monitors the temperature inside the chamber to maintain its stability. The power of the heating component needs to be adjusted according to the different blood components. The temperature sensor is a DS18B20, but other models can be used as needed. The controller is a PLC circuit board, but other devices capable of controlling the temperature sensor can be used as needed to reduce costs.

[0051] The blower section is fixed with a grid-shaped support plate 102. The support plate 102 divides the blower section into a blower cavity located in the middle and multiple placement cavities surrounding the outside of the blower cavity. The blower assembly 3 is installed inside the blower cavity.

[0052] The blower cavity has multiple air inlets 103 on its side wall. The blower cavity is connected to the external environment of the housing 1 through the air inlets 103. The multiple air inlets 103 form the air intake end of the blower section.

[0053] The placement cavity includes: corner cavities located at the four corners of the blower cavity and side cavities located on the four sides of the blower cavity. A battery compartment is provided in the corner cavity, and a dust filter is provided in the side cavity. The air inlet 103 penetrates through the side cavity.

[0054] The partition 101 has an air inlet 104 corresponding to the blower assembly 3, and the air inlet of the heating part and the air outlet of the blower part are connected through the air inlet 104.

[0055] A plurality of support columns 105 are fixedly provided on the end face of the partition 101 located in the heating section. The end of the support column 105 away from the partition 101 is fixedly connected to the inner wall of the box 1. The plurality of support columns 105 are evenly distributed between the partition 101 and the inner wall of the box 1.

[0056] The heating section is provided with a plurality of reinforcing plates 106, which are evenly distributed on the outer side of the inner wall of the housing 1. The two sides of the reinforcing plates 106 are fixedly connected to the inner wall and the outer wall of the housing 1, respectively.

[0057] The reinforcing plate 106 has multiple mounting holes, and a heat insulation ring is provided inside the mounting holes. The heating component 2 is located inside the heat insulation ring.

[0058] The partition 101 is covered with a reflective heat insulation film on the end face of the heating part to reduce the heat loss of the heating part. In addition, the reflective heat insulation film can also be attached to the end face of the outer wall of the box located on the heating part as needed.

[0059] The heating section is provided with a plurality of air outlets 107 at the end away from the blower section. The air outlets 107 are opened on the outer wall of the housing 1, and the plurality of air outlets 107 form the air outlet end of the heating section.

[0060] In some embodiments, to ensure the portability and lightweight of the device itself, rigid plastic is used as the main material of the box. Insulation cotton is attached to the end face of the inner wall of the box near the partition, and a windproof plastic film is attached to the end face of the insulation cotton near the blower assembly. With the help of the windproof plastic film and insulation cotton, the blower assembly is prevented from blowing directly on the inner wall of the box, thereby reducing the impact of the blower assembly on the internal temperature of the box.

[0061] In other embodiments, the air inlet of the blower can be opened on the bottom surface of the outer wall of the box, multiple air inlets can be opened along the edge of the partition, and the axial fan can be replaced with a centrifugal fan. In this case, air enters from the bottom of the box and is blown towards the air inlet on the edge of the partition by the centrifugal fan, and enters the heating part through the air inlet, which also avoids the blower assembly blowing directly onto the inner wall of the box.

[0062] Multiple connecting posts 4 are fixedly provided on the outer wall of the box 1. Connecting plates 401 are fixedly provided at both ends of the connecting posts 4. The end of the connecting plate 401 away from the connecting posts 4 is fixedly connected to the outer wall of the box 1.

[0063] The connecting column 4, the outer wall of the box 1, and the two connecting plates 401 form a ring structure for fixing the lifting strap.

[0064] The top of the box 1 is equipped with an insulation cover 5;

[0065] The heat insulation cover 5 is provided with a sealing boss 501 that matches the box body 1 on the end face of the box body 1. The outer wall of the sealing boss 501 is in contact with the inner wall of the box body 1.

[0066] A handle 502 is fixed on the other end face.

[0067] Work process:

[0068] When the clinic sends a blood transfusion request through the hospital information system, the blood transfusion staff puts the blood components into the box 1, turns on the blower assembly 3 and the heating assembly 2, and adjusts the heating assembly 2 to the power corresponding to the temperature required by the blood components through the controller.

[0069] At this time, the blower assembly 3 draws air from outside the box 1. The air flows through the air inlet 103, dust filter, axial fan, and blower 104 in sequence, and enters the heating chamber. Under the influence of the chrome-plated heating wire, the air heats up and heats the inner wall of the box 1, thereby maintaining the temperature of the blood bag. At the same time, the heated gas flows out through the air outlet to prevent air backflow from causing the temperature to be difficult to control.

[0070] The blood components are reheated inside the box and continue to be heated and kept warm during transportation until they are delivered to the ward or operating room. This method is especially suitable for transporting blood components between multiple buildings in large hospitals.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
