Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical heating, in particular to a heating system based on bionic honeycomb flow guide and double-redundancy temperature control. BACKGROUND

[0002] Plasma is a common blood product in medical treatment. Plasma usually needs to be frozen for preservation, and needs to be thawed and heated to near human body temperature before use. Too high temperature will cause denaturation of plasma protein, and too low temperature will affect injection and active factors At present, the traditional plasma heating usually adopts water bath heating method. However, water bath heating needs to immerse multiple plasma bags in constant temperature water, which causes the surrounding water pressure to be greater than the pressure in the plasma bag, so as to possibly cause contaminants to enter the plasma bag, especially in the case that the plasma bag is poorly sealed, which increases the risk of bacterial or other pathogen contamination. Therefore, the hot air heating method gradually replaces the water bath immersion heating method. However, the conventional hot air heating method directly blows hot air to the hanging area of the plasma bag by using a hot air blower. The hot air flow quickly flows through the surface of the plasma bag. This causes the plasma bag to exchange heat with the inner layer of the plasma bag close to the plasma bag, and the outer layer of the plasma bag far from the plasma bag is difficult to exchange heat with the plasma bag, that is, the utilization rate of hot air flow per unit time is reduced, thereby affecting the heating speed of the plasma. Increasing the temperature of the air flow is easy to cause local overheating of the plasma bag and affect the activity of the plasma.

[0003] Therefore, the existing hot air heating method is difficult to quickly heat the plasma bag due to the low direct blowing heat exchange rate, and when the temperature of the hot air is increased to utilize large temperature difference to heat the plasma bag, it is easy to cause local overheating of the plasma bag and affect the activity of the plasma.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, this invention provides a heating system based on biomimetic honeycomb flow guidance and dual redundant temperature control, comprising: Circular air duct 1, a hot air component generates a circulating hot airflow inside the circular air duct 1; The guide plate 3 is set inside the annular air duct 1 and located on the exhaust side of the hot air assembly, and the guide plate 3 is evenly and densely covered with multiple honeycomb holes 311. Furthermore, multiple plasma bags are suspended on the exhaust side of the annular duct 1 via hooks 41. The guide plate 3 disperses the hot airflow into multiple streams through honeycomb holes 311 to form turbulence on the surface of the plasma bags, thereby heating the plasma inside the plasma bags.

[0021] Specifically, the hot airflow in the annular duct 1 is divided into multiple airflows after passing through multiple honeycomb holes 311 on the guide plate 3. The multiple airflows continue to impact the surface of the plasma bag and collide with each other, generating turbulence on the surface of the plasma bag. The turbulence increases the speed of heat exchange between the airflows and the plasma bag, thereby improving the heat exchange speed between the hot airflow and the plasma bag and realizing rapid heating of the plasma bag.

[0022] The heating system also includes an infrared temperature sensor 5, which is installed on the annular duct 1 and its measuring part is placed inside the annular duct 1 and faces the hanging area of ​​multiple plasma bags to measure the temperature of the plasma bags. Thin-film temperature sensor 6, which can be attached to the surface of the plasma bag to measure the temperature; Furthermore, the temperature sensor 5 and the thin-film temperature sensor 6 together form a dual-redundant architecture for detecting the temperature of the plasma bag, so as to detect the temperature of the plasma bag in real time and feed it back to the controller. The controller controls the outlet temperature of the hot air component based on the difference between the feedback temperature and the preset threshold.

[0023] Specifically, the infrared temperature sensor 5 is a regional temperature sensor that can simultaneously detect the temperature of multiple plasma bags within a region, thereby obtaining the surface temperature of each plasma bag. The infrared temperature sensor 5's multi-object temperature detection is a conventional technology and will not be elaborated further.

[0024] Furthermore, the thin-film temperature sensor 6 is attached to the surface of the plasma bag using an adhesive method. This means that the thin-film temperature sensor 6 is attached to the plasma bag before it is hung for heating. The thin-film temperature sensor 6 can detect the surface temperature of the plasma bag, thus forming a dual-redundant temperature measurement architecture with the infrared temperature sensor 5, effectively reducing the probability of the plasma bag overheating.

[0025] The present invention aims to heat the suspended plasma bag by generating hot airflow in an annular air duct, and to regulate the airflow by using a guide plate 3 with multiple honeycomb holes 311 to form multiple airflows impacting the plasma bag, thereby creating turbulence on the surface of the plasma bag to increase the heating speed. Furthermore, the invention utilizes an infrared temperature sensor 5 and a thin-film temperature sensor 6 to form a dual-redundant temperature measurement architecture to measure the surface temperature of the plasma bag, effectively preventing the plasma bag from overheating.

[0026] Compared to conventional hot air heating, this invention disperses the hot airflow into multiple streams that impact the surface of the plasma bag, creating turbulence on the surface to improve heat exchange efficiency and thus increase the heating speed.

[0027] In addition, the annular duct 1 allows the airflow to circulate continuously inside, without introducing air from the complex external environment, reducing germ contamination, and reducing the heat required to reheat the airflow, thus lowering energy consumption.

[0028] Furthermore, the interior of the annular duct 1 can be coated with a sterilization coating, such as a silver ion coating, to reduce bacterial contamination.

[0029] like Figure 1As shown, the annular duct 1 is assembled from two horizontal sections and two curved sections. The hot air assembly includes a fan 2 installed on the horizontal section of the annular duct 1. An array of heating elements 21 are arranged on the air intake side of the fan 2 to heat the airflow drawn in by the fan 2 and form an annular hot airflow in the annular duct 1.

[0030] Furthermore, the annular duct 1 has a modular structure, allowing for complete disassembly, cleaning, and disinfection. The vertical structure of the annular duct 1 also allows condensate from frozen blood plasma bags to be transported by airflow to the lower horizontal section, thus avoiding interference with the heating element 21 and fan 2. Moreover, after disassembling the annular duct 1, the condensate can be completely removed. In this embodiment, the heating element 21 is composed of an array of multiple PTC ceramic heating modules. It heats up based on the temperature set by the host. The airflow drawn in by the intake side of the fan 2 is heated into hot airflow by the heating element 21.

[0031] Although the honeycomb holes 311 on the guide plate 3 can achieve the function of diverting and guiding the flow, the multiple airflows generated by the honeycomb holes 311 diverting the flow on the guide plate 3 are blown out horizontally and at a relatively high speed. As a result, the airflows on the surface of the plasma bag will collide with each other and generate turbulence, which will quickly pass through the plasma bag and move away, making it difficult for a large number of turbulent areas to exchange heat around the plasma bag.

[0032] Therefore, as Figure 2 As shown, the guide plate 3 includes multiple layers 31, which are installed in parallel to each other. Each layer 31 is densely covered with multiple honeycomb holes 311, and the honeycomb holes 311 on two adjacent layers 31 are staggered.

[0033] In this embodiment, by setting the guide plate 3 as a honeycomb-like structure composed of multiple layers 31 with honeycomb holes 31, and staggering the honeycomb holes 311 on adjacent layers 31, the airflow velocity can be effectively reduced when the airflow passes through.

[0034] Furthermore, due to the obstruction of multiple layers 31, the airflow generates turbulence inside the guide plate 3, thereby causing the airflow discharged from the guide plate 31 to form a turbulent area at the outlet and cover the entire area where the plasma bag is suspended, thereby increasing the heating speed of the plasma bag by the hot airflow.

[0035] Furthermore, the guide plate 3 also includes a plate frame 32, and multiple layers 31 are installed sequentially on the plate frame 32 at fixed intervals, and the plate frame 32 is installed on the inner wall of the upper horizontal section of the annular air duct 1.

[0036] In this embodiment, the layer plates 31 are installed sequentially at fixed intervals using the plate frame 32. This not only achieves the fixed interval installation according to the simulation design requirements (the simulation design before production ensures that the turbulent area of ​​the airflow covers the hanging area of ​​the plasma bag, which is a conventional design process and will not be elaborated further), but also enables the overall assembly and disassembly of the guide plate 3, thereby avoiding the impact of airflow distribution caused by the spacing change due to independent installation.

[0037] Furthermore, each honeycomb hole 311 of the guide plate 3 is provided with multiple protrusions 312, which are evenly distributed on the inner wall of the honeycomb hole 311.

[0038] In this embodiment, the inner wall of the honeycomb hole 311 is provided with protrusions 312. When the airflow passes through, it will collide with the protrusions 312, thereby generating the Karman vortex street phenomenon. That is, a single airflow will be dispersed into continuous and alternating airflow vortices. After passing through the guide plate 3, the collision between the airflow vortices can form more complex turbulence in the suspension area of ​​the plasma bag, further increasing the heating speed.

[0039] Among them, the Karman vortex street is an important phenomenon in fluid mechanics and can often be encountered in nature. When a steady flow passes around certain objects under certain conditions, double rows of linear vortices with opposite rotation directions and regular arrangement will periodically fall off on both sides of the object. After nonlinear action, the Karman vortex street is formed.

[0040] Based on the above embodiments, when the dual-redundant temperature measurement architecture consisting of infrared temperature sensor 5 and thin-film temperature sensor 6 detects that the surface temperature of the plasma bag is higher than the threshold, it is necessary to reduce the heat generation of the heating element 21. However, the cooling of the heating element 21 requires a process. During this process, in order to effectively reduce the temperature rise of the plasma bag, the following preferred embodiments are provided. like Figure 5 As shown, a stepper motor is installed outside the annular duct 1. The stepper motor shaft rotates and extends into the annular duct 1, and the stepper motor shaft is fixedly connected to the guide plate 3 to drive the guide plate 3 to rotate in the annular duct 1 and adjust the airflow direction.

[0041] In this embodiment, a stepper motor is installed on the annular duct 1. The stepper motor is controlled by a controller (the conventional control system of existing equipment, which will not be described in detail). When the dual-redundant temperature measurement architecture detects that the temperature is higher than the threshold, the angle of the guide plate 3 is adjusted by controlling the stepper motor so that the exhaust end of the honeycomb hole 311 is at a certain angle to the airflow direction of the annular duct 1. This increases the resistance of airflow circulation, reduces the airflow circulation speed, and thus reduces the heat exchange effect. This can effectively control the temperature rise of the plasma bag and prevent the plasma bag from overheating.

[0042] Of course, different temperature thresholds can be set. When the temperature exceeds different thresholds, the guide plate 3 is provided with a corresponding adjustment angle. That is, the higher the detection temperature of the plasma bag, the larger the rotation angle, and vice versa.

[0043] To prevent air leakage caused by gaps between the guide plate 3 and the annular duct 1 when the guide plate 3 rotates, the following preferred embodiment is provided.

[0044] like Figure 6 As shown, a sealing ring 11 is provided inside the annular duct 1. The outer wall of the sealing ring 11 is installed on the inner wall of the annular duct 11. An annular groove 111 is provided on the inner wall of the sealing ring 11. The cross-section of the annular groove 111 is arc-shaped, and the guide plate 3 is slidably installed in the annular groove 111.

[0045] In this embodiment, a sealing ring 11 is installed inside the annular pipe 1, and the inner wall of the sealing ring 11 has an annular groove 111. The guide plate 3 can be installed inside the annular groove 111. The annular groove 111, located at the end of the sealing ring 11, can prevent the guide plate 3 from rotating excessively and disengaging from the annular groove 111. Furthermore, the outer wall of the guide plate 3 can slide and seal against the annular groove 111, thereby achieving a seal for the guide plate 3 at any rotation angle.

[0046] Based on the above embodiments, in order to improve the sealing effect, such as Figure 7 As shown, a ceramic ring 33 is installed on the outer peripheral wall of the guide plate 3, and a ceramic layer 112 is plated on the inner wall of the annular groove 111. The ceramic ring 33 and the ceramic layer 112 are in frictional contact to achieve a seal.

[0047] In this embodiment, a ceramic ring 33 is installed on the guide plate 3, and a ceramic layer 112 coating is plated in the annular groove 111. The sealing is achieved through frictional contact between the ceramic ring 33 and the ceramic layer 112.

[0048] Based on the above embodiments, the plasma bags are manually suspended inside the annular duct 1. To facilitate the suspension of the plasma bags, the following preferred embodiments are provided.

[0049] like Figure 3 As shown, it also includes a cover plate 4, which has a slot on the upper side of the peripheral wall of the upper horizontal section of the annular air duct 1. The slot is located on the exhaust side of the fan 2, and the cover plate 4 is detachably installed on the slot, and the hook 41 is installed on the bottom of the cover plate 4. Furthermore, multiple slots and cover plates 4 are sequentially arranged along the direction of airflow to simultaneously suspend and heat multiple plasma bags.

[0050] In this embodiment, the annular duct 1 has multiple slots on the exhaust side of the fan 2, and each slot is covered with a cover plate 4. A hook 41 is installed at the bottom of the cover plate 4. When it is necessary to hang the plasma bag, after the cover plate 4 is removed, the plasma bag is installed on the hook 41, and the cover plate 4 is put back on the slot. The plasma bag is then suspended on the exhaust side of the fan 2 inside the annular duct 1.

[0051] Furthermore, such as Figure 4 As shown, the cover plate 4 is arc-shaped and matches the arc of the upper horizontal section of the annular air duct 1. Multiple threaded holes 42 are provided on the cover plate 4 along its arc wall. Threaded hanging rods 421 are installed in the threaded holes 42, and hooks 41 are installed at the bottom of the hanging rods 421. The height of the hook 41 can be adjusted by rotating the threaded rod 421, so that the multiple hooks 41 are staggered in height and back, and the multiple plasma bags are staggered in distribution within the annular duct 1.

[0052] In this embodiment, the hook 41 is installed on the threaded rod 421, and the threaded rod 421 is installed in the threaded hole 42 provided on the cover plate 4. By rotating the threaded rod 421, the height of the hook 41 and the plasma bag suspended on it can be adjusted. In other words, multiple plasma bags can be adjusted to be staggered in height, thereby avoiding the plasma bags from blocking the airflow and enabling multiple plasma bags to be heated quickly.

[0053] Furthermore, the annular duct 1 of the plasma bag suspension area can be made of transparent material, so that it can be observed and adjusted so that the thin side of the plasma bag faces the airflow direction, and the turbulence generated by the airflow flows through the two side walls with the largest area of ​​the plasma bag.

[0054] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
