Description

1 TARIFF THERMAL STABILIZER FEVER REDUCER TECHNICAL FIELD The invention relates to reducing fever in febrile patients, and involves cooling the body along with the fever. This is achieved by heating the arms and legs, creating a temperature difference between them and the environment. By drawing heat from the limbs, the fever remains balanced without altering the body's net temperature. It includes a technology that will cause the heat to drop from the arms. In this context, the invention involves reducing heat from the arms. an actuator that directs hot and cold air by receiving signals from a sensing circuit group. 10 heat exchanger structures that perform air cooling and heating functions simultaneously with their group It encompasses the whole. PREVIOUS TECHNIQUE Fever in the body makes it difficult for bacteria and viruses to survive. Hypothalamus-initiated vasoconstriction and muscle contraction reflexes 15 As a result, body heat loss decreases and core temperature increases. This biological process is emerging as a defense mechanism against infections. It is a part of it. In some medically necessary cases, it is administered internally to reduce fever. or external interventions are applied. One of the externally applied methods is on the body. Apply a warm compress to the head and armpit areas where excessive temperature increase is observed. 20 It is to implement. On the other hand, in the case of fever, the thermoregulation system affects peripheral blood flow. as a result of reducing it, extending from the shoulders and hips to the fingertips It is known that the limbs get cold. Arms and legs, along with their fingers, are part of the body as a whole. The surface area is approximately 47% in infants and approximately 27% in adults. It creates (www.health.state.mn.us). The temperature difference between the surface of these limbs and the environment. Due to the decrease in the temperature difference, heat transfer from these regions to the environment decreases, therefore The body's overall heat dissipation is insufficient, and the fever naturally subsides. It is becoming more difficult. Fever reduction methods are generally divided into two categories: internal and external applications. 30 They are separated. Internal applications are pharmacological in nature and include antipyretic drugs. It is implemented and is not the subject of the present invention. External applications, however, are not included in any traditional methods performed without the need for a device or with device assistance 2 These are solutions. The most common in traditional applications is where high temperatures are observed. This involves applying warm compresses to the affected areas. In addition, for external applications, it provides phase change in gel consistency. Polymer or hydrogel-based materials that cool through evaporation. There are fever-reducing patches available (https: / / www.watsons.com.sg / extra-cooling-5 (fever-gel-patch-adults-up). In addition, it has a more complex structure compared to gel patches. Electronically controlled cooling devices have also been suggested. The system developed by Balding (2002) allows for multiple applications in hospital settings. a fever suppressor equipped with a temperature sensor and connected to a central control unit It is a device. The system collects temperature information from specific points on the patient's body and 10 Heat transfer from the body surface by a fan system that provides a flow of chemical refrigerant gas. It performs this function and also allows for intravenous drug administration. This structure, It is based on a combination of active air circulation and pharmacological support. Another invention proposed by Lin (2004) involves a thermo-electric A belt containing a cooling element (Peltier element) will have its cooling surface in contact with the front 15 It is used in this way to reduce fever. This system is only for the forehead. It applies local cooling to the area and has the ability to regulate overall body temperature. It is not available. Mazal (2010) described an aqueous solution containing 1-5% acetic acid and diaphoretic plant extracts. It suggests lowering body temperature by applying the solution to the skin. This 20 The effect of the solution is surface heat extraction through chemical cooling and evaporation. It is based on the principle of ensuring. In the study by Chan et al. (2010), adult febrile Patients were given cold blankets, warm sponges, and ice packs; The applications increased the tremor and without pharmacological support, the desired level was not reached. It has been reported to be ineffective. In light of this information, all current external treatments remove heat from the body. It is based on the principle of heat transfer. However, these applications affect the body. thermal balance that it develops as a protective measure during the fight against infection This leads to its deterioration and negatively impacts the thermoregulation system. Head 30 and when cooling is applied to areas that are already at a high temperature, such as the fuselage, Net heat loss is increasing, but sufficient heat is being obtained from the limbs (arms and legs). Because the body cannot eliminate the thermal balance, the thermal equilibrium is disrupted. This situation leads to the body becoming infected. 3 interruption of the beneficial heat it produces during the struggle and the healing process This causes it to lengthen. In conclusion, current techniques reduce fever by drawing heat away from the body. It is based on the principle that the basic technical problem is to apply these methods to the total body heat. disrupting its balance and thus the beneficial internal heat needed to fight infection. the disappearance of its effects.

The invention involves heating cold extremities of the body, namely the arms and legs, thereby improving the condition of these areas. The aim was to raise their temperatures to the level of head and body temperature. Thus, 20 By increasing the temperature difference between the surfaces of the limbs and the environment, the arms and legs... This allows more heat to be released into the environment. In this way, the current invention allows the body to... It offers an approach that supports the natural heat dissipation mechanism. The invention involves applying and then extracting heat from the surfaces of the arms and legs. The processes are applied sequentially, so that the total amount of heat in the body remains constant at 25. This process is maintained through natural thermal processes, without causing sudden drops in the body's overall temperature. This is achieved while maintaining balance. As a result, the net amount of heat in the body and the average temperature remain constant. Thanks to this, the process of fighting infection is not interrupted; however, the head and by reducing body temperature, the negative effects of fever, especially the risk of seizures, 30 is decreasing significantly. The physical basis of the invention is the three parts of the human body shown in Figures 1-1, 1-2 and 1-3. This is summarized with different drawings. The schematic drawing in Figure 1-1 is shown in Figure 1-2 with a rounded shape. 4 The schematic drawing and model drawing are shown in Figures 1-3. The body includes the head, neck, and The torso is filled with diagonally patterned padding, while the arms and legs, including the fingers, are unfilled. shown. Body parts indicated with shaded fill are center body (MV) and Body parts shown without filler are referred to as extension body (UV). Fever In this situation, the MV surface temperature rises above the normal average body temperature, UV 5 from experiences where the surface temperature dropped below the normal average body temperature It is known that the deviation of MV and UV surface temperatures from the average temperature indicates fire. Depending on the severity, it can vary by several degrees. Along with rising fever, the body's MV (mediated airway) the temperature difference between the surface and the environment is increasing, the temperature difference between UV and the environment is decreasing. The increasing temperature difference reduces heat transfer per unit surface area, i.e., the amount of cooling, by 10. As the temperature difference decreases while increasing the temperature, the cooling per unit surface area decreases. Thus, the body can only utilize a limited surface area (in infants, the total surface area) 53% (73% in adults) release heat into the environment with a relatively high temperature difference. It transfers far less heat than the rest during the transfer process. High In febrile cases, if the UV surface temperature approaches the ambient temperature, this 15 This means that the heat released from surfaces to the environment approaches zero. This situation is called high fever. This means that heat transfer from the body to the environment occurs only through the MV surface. It is coming. Figure 2 shows the model drawing of the human body with MV, UV, and ambient temperature. The levels are shown. The highest temperature for a feverish patient relative to the ambient temperature is 20. The portion that is affected is MV. However, MV, due to this temperature difference, allows heat to escape from its limited surface area. It is able to emit very little or no heat from the UV surface, i.e., from the arms and legs. They cannot expel it. This is because of the shrinkage of the skin and blood vessels in the limbs. constriction occurred according to Gayto (Gayto AC, 2011. Textbook of Medical Physiology, 12th Edition, This was reported by USA. 2004. As a result, in febrile patients, the arms and legs 25 It acts as a (UV) insulating block and forms a barrier to heat dissipation. The invention works by raising the temperature of this insulator by applying heat from its UV surface. It is based on the principle of relatively increasing the block conductivity. With the application that is the subject of the invention By applying heat to the hands and feet, the skin surface area increases and the blood vessels become more prominent. By expanding, blood flow accelerates. As with all substances, UV components have a 30%... Due to reasons such as the increase in heat transfer coefficients with increasing temperature, from MV Heat transfer to the environment increases. As long as the situation causing the fire continues, the system... It attempts to bring UV radiation into an insulating barrier state. The system described within the scope of the invention elicits the body's response as described above. By monitoring the process, it manages it as a heating + cooling application. In this way, both In MV, the excessive increase in temperature was prevented, and the net amount of heat in the body remained unchanged. is happening. The total heat the body will release to the environment is from the entire body surface, i.e., MV + UV 5. This occurs from the surface. On the other hand, it is an internal fire suppression practice. When fever-reducing medication is used, the UV surface temperature increases and It is also known from experience that the fever subsides afterwards. The reason for this is fever. The effect of the lowering medication increases UV heat conductivity, meaning that in this part of the body... It is the reduction of thermal resistance. 10 LIST OF FIGURES Figure 1-1.
