Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a body temperature maintenance structure during surgery and a method for using the structure. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables. Their effectiveness is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] During a long operation, the patient's body temperature management is a crucial link. If the patient is not properly warmed, a series of serious disadvantages may occur, which not only affect the smooth progress of the operation, but may also have an adverse effect on the patient's postoperative recovery.

[0004] First, during surgery, patients usually receive anesthetic drugs, which may inhibit the patient's temperature regulation center, causing a drop in body temperature. The inhibition of the temperature regulation center makes it impossible for the patient to effectively maintain a normal body temperature, thereby increasing the risk of hypothermia.

[0005] Next, low body temperature will have many negative effects on the patient's body. Low temperature stimulation will cause the patient's peripheral blood vessels to contract, increase the burden on the heart, and affect blood circulation. Secondly, low body temperature may interfere with the function of coagulation factors and increase the risk of surgical bleeding. In addition, patients in a low temperature state may feel cold and shiver, increasing physical and psychological discomfort.

[0006] Furthermore, if the patient is not kept warm in a strange and cold operating environment, his or her anxiety and fear will be aggravated. This psychological discomfort will not only affect the patient's overall experience, but may also affect the effectiveness of the operation and postoperative recovery.

[0007] Finally, operating rooms are usually kept at a lower temperature to maintain a sterile environment and the comfort of surgical staff. However, such an environment may further increase the risk of hypothermia for patients. Hypothermia may delay the healing process of surgical wounds and affect the patient's postoperative recovery.

Finally, the control strategy is adjusted according to the patient's parameter changes to improve the adaptive ability;

[0026] The anomaly detection module is used to detect changes in temperature and humidity of the sensor components. If an abnormality is detected, an alarm message is sent to the observation platform where the doctor performs the operation.

[0027] In the present invention, a method for using a body temperature maintenance structure during surgery comprises the following steps:

[0028] Step 1: The liner is composed of an insulation layer and a heating layer. First of all, under the action of the insulation layer, the high-count and high-density pure cotton yarn fabric has a high density, a soft and delicate hand feel, is non-irritating to the skin, is safe and reliable, and has good anti-allergic properties, making it suitable for people of all physiques; Outlast acrylic air-conditioning fiber is a smart fiber that can automatically adjust the temperature of the quilt according to changes in ambient temperature to keep the human body at a comfortable body temperature. Outlast acrylic air-conditioning fiber is made of environmentally friendly materials, is harmless to the human body, and has good antibacterial properties, which helps to keep hospital quilts clean and healthy; the 3M thermal insulation fiber layer has excellent thermal insulation properties, which can effectively lock in heat, prevent heat loss, and make the quilt warmer; it plays a role in improving the thermal insulation effect and comfort of the liner, and is embedded in the inner cavity of the thermal insulation layer. A Morden material layer is placed, and the Morden material layer has good air permeability and moisture absorption, which can keep the inside of the liner dry and comfortable. Then, under the setting of the thermosensitive phase change material, it can absorb or release heat according to the changes in ambient temperature, which makes the liner more calm when dealing with extreme temperature changes, and can provide patients with a more stable and comfortable body feeling. Furthermore, as a part of the heating layer, the graphene material has extremely high thermal conductivity and can quickly transfer heat, thereby improving the heating progress. At the same time, three electric heating wires are configured, which can perform local heating in different areas to meet the patient's personalized heating needs and improve the patient's comfort during surgery. The infrared heating film is used in conjunction with the electric heating wire to realize infrared heating, ensuring that a variety of heating methods can be automatically switched or used in combination under different conditions to achieve the best temperature control effect.

[0029] Step 2: Place the liner in the inner cavity of the thermal insulation blanket, ensure alignment, put the fixing frame on the thermal insulation blanket, turn the operating block, the operating block drives the threaded rod to rotate, and drives the positioning block to move downward under the action of the fixing frame. When the positioning block moves downward, the two sides of the thermal insulation blanket are in close contact with the positioning block and the fixing frame respectively, so that the thermal insulation blanket and the liner can be positioned to prevent the thermal insulation blanket and the liner from deviation during use, and it is also convenient for the subsequent disassembly of the liner to clean the thermal insulation blanket.

[0030] Step three: Use the temperature sensor and humidity sensor to detect the temperature and humidity under the thermal blanket respectively. The microcontroller receives the data from the temperature sensor and the humidity sensor. The temperature adjustment algorithm module calculates the temperature amplitude that needs to be adjusted according to the temperature and humidity data received by the microcontroller and the patient's set value. Then the microcontroller transmits the control instruction to the drive module 1 and the drive module 2. The drive module 1 controls the electric heating wire to turn on and adjust the heating temperature. The drive module 2 controls the infrared heating film to turn on and adjust the heating temperature. There are three electric heating wires, which can heat different parts of the patient separately as needed, thereby improving the patient's comfort during surgery and performing local heating in different areas to meet the patient's personalized heating needs.

[0031] Beneficial effects: The technical solution of the present application has the following technical effects: the present invention has the advantages of excellent heat preservation, stable positioning, intelligent temperature control and personalized heating.

[0032] In actual application, the thermal blanket has demonstrated excellent performance. First, under its structural design, when the heating layer automatically starts and releases heat, the thermal insulation layer plays a vital role. The thermal insulation layer is composed of a variety of high-count and high-density pure cotton yarn fabrics, Outlast acrylic air-conditioning fibers, 3M thermal insulation fiber layers and other high-efficiency thermal insulation materials. They work together to effectively lock in heat and prevent heat loss, ensuring that patients can enjoy a constant temperature and comfortable experience during use.

[0033] Furthermore, when the liner is placed in the inner cavity of the thermal insulation blanket, the fixing assembly can position the thermal insulation blanket and the liner, which not only avoids the thermal insulation blanket and the liner from deviating during use, ensuring the stability and safety of use, but also greatly facilitates the removal of the liner and the cleaning of the thermal insulation blanket, thereby improving the usability and maintainability of the product.

[0034] Furthermore, in terms of temperature control, the temperature regulation algorithm module works closely with the microcontroller, and can automatically adjust the heating temperature of the electric heating wire and the infrared heating film according to the ambient temperature, the patient's body temperature and the preset temperature control requirements. This intelligent temperature control method not only realizes the flexible switching or combined use of electric heating and infrared heating to meet the temperature control requirements under different conditions, but also ensures the best temperature control effect, providing patients with a personalized comfort experience. In addition, there are three electric heating wires. In actual applications, medical staff can choose the appropriate heating strategy and temperature control strategy after comprehensive consideration of multiple factors such as the surgical site, the patient's physique and the ambient temperature. For example, for the surgical area that needs to maintain a higher body temperature, the power of the heating wire can be increased or the heating time can be extended accordingly; for those parts that are more sensitive to temperature changes, the power of the heating wire can be reduced or intermittent heating can be used to avoid the discomfort caused by overheating. Compared with the traditional integrated heating method, localized heating treatment can more accurately control the heating range and temperature, greatly improving the patient's comfort during the operation and fully meeting the needs of personalized heating. Infrared heating is suitable for situations where rapid heating is not required. Infrared heating can be selected to maintain a constant temperature and reduce irritation to the patient's skin.

[0035] Finally, the thermal blanket is also equipped with three electric heating wires, which heat different parts of the patient's body. This design not only improves the accuracy and efficiency of heating, but also enables personalized temperature adjustment according to the patient's specific needs, further improving the comfort and practicality of the product.

8. A method for using a body temperature maintenance structure during surgery, characterized in that: The method comprises the following steps: Step 1: The inner liner (2) is composed of a heat preservation layer (21) and a heating layer (22). First, under the action of the heat preservation layer (21), the high-count high-density pure cotton yarn fabric (211) has a high density, a soft and delicate touch, is non-irritating to the skin, is safe and reliable, and has good anti-allergic properties, suitable for people of all physiques. The Outlast acrylic air conditioning fiber (212) is a smart fiber that can automatically adjust the temperature of the quilt according to changes in ambient temperature to keep the human body at a comfortable body temperature. The Outlast acrylic air conditioning fiber (212) is made of environmentally friendly materials, is harmless to the human body, and has good antibacterial properties, which helps to keep the hospital quilt clean and healthy. The 3M thermal insulation fiber layer (213) has excellent thermal insulation properties, can effectively lock in heat, prevent heat loss, and make the quilt warmer. This improves the thermal insulation effect and comfort of the inner liner (2), and a Modal fiber is embedded in the inner cavity of the heat preservation layer (21). The material layer (214) has good air permeability and moisture absorption, and can keep the interior of the liner (2) dry and comfortable. Then, under the setting of the thermosensitive phase change material (215), it can absorb or release heat according to the change of the ambient temperature, so that the liner (2) is more relaxed when dealing with extreme temperature changes, and can provide the patient with a more stable and comfortable feeling. Furthermore, the graphene material (221) is a part of the heating layer (22). The graphene material (221) has a very high thermal conductivity and can quickly transfer heat, thereby improving the heating progress. At the same time, three electric heating wires (223) are configured, which can perform local heating in different areas to meet the personalized heating needs of patients and improve the comfort of patients during surgery. The infrared heating film (222) is used in conjunction with the electric heating wire (223) to achieve infrared heating, ensuring that multiple heating methods can be automatically switched or used in combination under different conditions to achieve the best temperature control effect. Step 2: Place the inner liner (2) in the inner cavity of the thermal insulation blanket (1) to ensure alignment, put the fixing frame (41) on the thermal insulation blanket (1), rotate the operating block (43), the operating block (43) drives the threaded rod (42) to rotate, and drives the positioning block (44) to move downward under the action of the fixing frame (41). When the positioning block (44) moves downward, the two sides of the thermal insulation blanket (1) are in close contact with the positioning block (44) and the fixing frame (41) respectively, so that the thermal insulation blanket (1) and the inner liner (2) can be positioned to prevent the thermal insulation blanket (1) and the inner liner (2) from deviating during use, and also facilitate the subsequent disassembly of the inner liner (2) so as to clean the thermal insulation blanket (1); Step 3: The temperature and humidity under the thermal blanket (1) are detected by using a temperature sensor (31) and a humidity sensor (32), respectively. The microcontroller (7) receives data from the temperature sensor (31) and the humidity sensor (32). The temperature adjustment algorithm module (6) calculates the temperature amplitude to be adjusted based on the temperature and humidity data received by the microcontroller (7) and the patient's set value. Then, the microcontroller (7) transmits the control instruction to the drive module 1 (224) and the drive module 2 (225). The drive module 1 (224) controls the electric heating wire (223) to turn on and adjust the heating temperature. The drive module 2 (225) controls the infrared heating film (222) to turn on and adjust the heating temperature. The number of electric heating wires (223) is three, and different parts of the patient can be heated separately according to needs, thereby improving the patient's comfort during surgery and achieving the effect of performing local heating in different areas to meet the patient's personalized heating needs.
