[0062] The patient sleep temperature control device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0063] Reference Figures 1 to 5 As shown, the patient sleep temperature control device provided according to an embodiment of the present invention includes a temperature control mattress assembly 10 , a temperature control cup assembly 20 , a temperature monitoring assembly 30 and a controller 40 .
[0064] Specifically, the temperature-controlled mattress assembly 10 includes a supporting bottom layer 101, a water-heating layer 102 disposed on the supporting bottom layer 101, a temperature-sensing layer 103 disposed above the water-heating layer 102, and a memory foam layer 104 disposed above the temperature-sensing layer 103, wherein a plurality of serpentine water circulation pipelines are disposed in the water-heating layer 102.
[0065] The supporting bottom layer 101 can be made of a high-density sponge material with appropriate hardness and support, and can provide a stable support for the entire mattress. The serpentine water circulation pipeline ensures a larger heating area and achieves uniform heat conduction. The serpentine water circulation pipeline can be connected to an external circulating water tank, and the circulating water tank is used to provide hot water of a predetermined temperature. The circulating water tank generally includes a water storage tank, a heater and a liquid pump. The heater is used to heat the water in the water storage tank, and then the liquid pump is used to transport it to the serpentine water circulation pipeline to form a circulating water circuit.
[0066] The temperature sensing layer 103 can monitor the temperature distribution of each area of the water heating layer 102 in real time and provide temperature feedback data to the controller 40. The memory foam layer 104 can be made of memory foam material, which has excellent touch and pressure dispersion performance. The memory foam material can adaptively deform according to the pressure of the human body, providing good support effect and comfort.
[0067] The temperature control quilt assembly includes an outer fabric layer 201, an air guide layer 202 arranged on the inner side of the outer fabric layer 201, a heating wire layer 203 arranged below the air guide layer 202, and a thermal insulation cotton layer 204 arranged below the heating wire layer 203. The air guide layer 202 is provided with a plurality of through air guide channels H202.
[0068] That is, the temperature control quilt component also adopts a multi-layer structure design, and the outermost layer is the outer fabric layer 201, which can be made of textile fabric with good air permeability and touch. The air guide layer 202 is designed on the inner side of the fabric, and a plurality of through air guide channels H202 are arranged inside. The air guide channel H202 can be connected to an external blower, and the external blower is used to supply air into the air guide duct, and the wind can be evenly introduced into the temperature control quilt component through the air guide duct. The heating wire layer 203 can be made of carbon fiber heating wire, etc., which has the characteristics of rapid heating and uniform temperature. When the wind sent into the air guide channel H202 passes through the heating wire layer 203, the heating wire layer 203 can be used to heat it to form hot air with a certain temperature, and the hot air is then emitted to the patient's body surface after passing through the thermal insulation cotton layer 204 and the outer fabric layer 201.
[0069] The temperature monitoring component 30 includes a headband 301 and a temperature monitor 302 provided on the headband 301. The headband 301 is suitable for being worn on the patient's head, and the temperature monitor 302 is suitable for monitoring the patient's body temperature data in real time. The temperature monitoring component 30 can continuously and accurately monitor the patient's body temperature. The monitoring data is transmitted to the controller 40 in real time by wireless or wired means to ensure the timeliness and accuracy of the monitoring.
[0070] The controller 40 is electrically connected to the temperature-controlled mattress assembly 10, the temperature-controlled quilt assembly and the temperature monitoring assembly 30, respectively, and is used to control the working state of the temperature-controlled mattress assembly 10 and the temperature-controlled quilt assembly according to the body temperature data. Exemplarily, the controller 40 uses a PID algorithm to automatically adjust the working parameters of the temperature-controlled mattress assembly 10 and the temperature-controlled cup assembly 20 according to the patient's body temperature change trend, thereby providing the patient with a suitable sleeping temperature, and can be adjusted in real time.
[0071] According to the patient sleep temperature control device provided by the embodiment of the present invention, a dual temperature control combining a water-heated mattress and an air-heated quilt is adopted. The serpentine water circulation pipeline in the water-heating layer 102 can provide a lasting and stable basic temperature guarantee, and the design of the air-guiding layer 202 can achieve rapid temperature response and adjustment. In particular, by setting a temperature monitor 302 on the headband 301 to monitor the patient's body temperature in real time, and the controller 40 intelligently adjusts the working state of the temperature-controlled mattress assembly 10 and the temperature-controlled quilt assembly according to the body temperature data, the patient's body temperature can be accurately controlled and closed-loop managed. This intelligent temperature control method not only solves the problems of uneven temperature distribution and inaccurate adjustment in traditional equipment, but also improves the comfort of the equipment through the layered structural design. The configuration of the memory cotton layer 104 and the thermal insulation cotton layer 204 further enhances the user experience. The device is particularly suitable for medical scenarios such as anesthesia recovery that require strict control of body temperature, and can provide patients with safer, more comfortable and personalized temperature adjustment.
[0072] In one embodiment of the present invention, the water-heating layer 102 includes an upper sealing film 1021 and a lower sealing film 1022 , and the upper sealing film 1021 and the lower sealing film 1022 are sealed to form a plurality of independent areas.
[0073] The serpentine water circulation pipeline includes a plurality of sub-pipelines 1023, and the plurality of sub-pipelines 1023 correspond one-to-one to the plurality of independent areas. Each of the sub-pipelines 1023 is arranged in the corresponding independent area and is connected to an external circulating water tank through an independent water inlet pipe and a water outlet pipe.
[0074] Exemplarily, the upper sealing film 1021 and the lower sealing film 1022 are sealed and connected at a preset position by a high-frequency heat-sealing process to form a plurality of independent areas. Correspondingly, the serpentine water circulation pipeline adopts a partition design and is composed of a plurality of independent sub-pipelines 1023. Each sub-pipeline 1023 corresponds to an independent area and is arranged in a serpentine coiling manner.
[0075] The precision and flexibility of temperature control are significantly improved by adopting a partitioned sealing design and independent sub-pipelines 1023. The setting of multiple independent zones enables differentiated temperature regulation in different parts to better meet the personalized needs of patients. Independent water inlet and outlet not only improves the response speed of regulation, but also enhances reliability and maintainability. Even if a problem occurs in a certain area, it will not affect the overall function.
[0076] In one embodiment of the present invention, a plurality of temperature sensors are disposed on the temperature sensing layer 103 , and the distribution positions of the temperature sensors correspond to the independent areas. The controller 40 controls the water temperature of each independent area according to the detection data of each temperature sensor.
[0077] In specific applications, the controller 40 can control the opening of each valve on the sub-pipeline 1023 according to the detection data of each temperature sensor and then control the flow of each sub-pipeline 1023, so as to achieve temperature adjustment for each independent area. Through the arrangement of multiple temperature sensors, the temperature of each area of the temperature-controlled mattress assembly 10 is independently controlled, ensuring the accuracy and stability of temperature control and the flexibility of different needs; not only meeting the personalized needs of different patients, but also providing a more scientific and humane temperature management method for medical care.
[0078] In one embodiment of the present invention, the air guide layer 202 includes an upper air permeable layer 2021 and a lower air permeable layer 2022, and a plurality of spaced support bars 2023 are provided between the upper air permeable layer 2021 and the lower air permeable layer 2022, and the air guide channel H202 is formed between the support bars 2023, and one end of the air guide channel H202 is connected to an external air supply fan.
[0079] The air guide channel H202 is provided with a plurality of air outlet holes H201 , and the plurality of air outlet holes H201 are sequentially spaced apart along the direction of the air guide channel H202 and penetrate the lower air permeable layer 2022 .
[0080] Exemplarily, the upper air-permeable layer 2021 and the lower air-permeable layer 2022 can be made of cloth with air-permeability to ensure that air can pass smoothly and diffuse evenly. The space between the upper air-permeable layer 2021 and the lower air-permeable layer 2022 is separated by a plurality of support strips 2023, which not only play a role in maintaining the distance between the layers, but also help form a regular air-guiding channel H202. The support strips 2023 can be made of EVA (ethylene-vinyl acetate copolymer) material, POE (polyolefin elastomer) material, etc., which have the characteristics of flexibility, lightness, certain strength, etc. It not only ensures that the air-guiding channel H202 has a ventilation cross-sectional area, but also ensures that the entire air-guiding layer 202 has appropriate strength and toughness.
[0081] In this embodiment, the air guide channels H202 are regularly distributed in strips under the division of the support strips 2023, and each air guide channel H202 is connected to an external blower, so that the airflow can be evenly distributed to each air guide channel H202 after entering the air guide layer 202.
[0082] In addition, in order to achieve more precise air supply, multiple air outlet holes H201 are designed on the air guide channel H202. These air outlet holes H201 are arranged in a spaced manner along the direction of the air guide channel H202 and all penetrate the lower air permeable layer 2022, so as to ensure that the air flow can be evenly diffused downward to the human body surface.
[0083] In a specific application, the controller 40 can adjust the speed of the blower according to the body temperature data, thereby changing the amount of air supplied. At the same time, in conjunction with the temperature regulation of the heating wire layer 203, coordinated control of the air temperature and air volume can be achieved, providing a more precise temperature regulation effect.
[0084] The structural combination of the upper air permeable layer 2021, the lower air permeable layer 2022 and the support strip 2023 forms a stable and reliable air guide channel H202 network; the design of the air outlet holes H201 arranged at intervals realizes the uniform distribution of air flow. This overall design not only ensures the air guide effect, but also maintains the softness and comfort of the quilt, while providing precise temperature regulation capabilities.
[0085] In some embodiments of the present invention, the temperature-controlled quilt assembly further includes a negative ion generating unit 2024, which is disposed in the air guide layer 202 and is used to release negative ions during air supply, and the controller 40 is capable of adjusting the release concentration of negative ions.
[0086] The negative ion generating unit 2024 can be ionized by high voltage or natural minerals, and can be distributed along the direction of the air guide channel H202 to ensure that the negative ions can be evenly released throughout the body. When the blower is working, the generated airflow not only has the function of temperature regulation, but also has the function of negative ion transmission, so that the negative ions can be evenly transported to the space around the patient's body surface through the air outlet H201 in the air guide channel H202. This design not only ensures the effect of temperature regulation, but also allows the negative ions to be fully released. Especially in medical places under air-conditioning environment, the continuous release of negative ions can improve the air quality and provide a more comfortable breathing environment.
[0087] In some embodiments of the present invention, the water heating layer 102 of the temperature-controlled mattress assembly 10 is provided with a phase change insulation unit, which includes a plurality of phase change capsules 1024, each of which is arranged on the water circulation pipeline, and each of which is encapsulated with a phase change material having a phase change temperature of 28 to 36°C.
[0088] The arrangement of the phase change capsule 1024 can be in a variety of ways, such as embedded or stacked, to ensure that the phase change capsule 1024 can fully contact the water circulation pipeline to ensure the heat transfer effect. Optionally, medical grade n-octadecane with a phase change temperature of 28-32°C, or hydrated salt with a phase change temperature of 30-34°C, or paraffin materials with a phase change temperature of 32-36°C, etc. These materials undergo phase change in the temperature range of 28 to 36°C, have a large phase change latent heat and good thermal stability. When the water temperature in the water circulation pipeline is higher than the phase change temperature, the phase change material absorbs excess heat and undergoes a phase change; when the water temperature drops, the phase change material releases the stored heat, thereby playing a dual role of temperature regulation and heat storage.
[0089] In this embodiment, the phase change capsule 1024 is arranged on the water circulation pipeline to form a distributed heat storage and release system, which uses the energy storage characteristics of the phase change material to provide a passive temperature regulation function, enhance temperature stability, and provide additional safety for temperature regulation. The distributed phase change capsule 1024 improves the uniformity of heat storage and release. In addition, the use of the phase change capsule 1024 also effectively reduces energy consumption and improves economic efficiency.
[0090] In one embodiment of the present invention, the phase change capsule 1024 includes a sealed capsule, a protective shell and a heat-conducting layer, wherein the sealed capsule is used to contain the phase change material, the protective shell is wrapped outside the sealed capsule, the heat-conducting layer is arranged between the sealed capsule and the protective shell, and the interior of the sealed capsule has a honeycomb structure to separate the phase change material into multiple independent units.
[0091] In this embodiment, the phase change capsule 1024 adopts a multi-layer composite structure design, and the outer layer is a protective shell, which can be made of soft plastic material or woven fabric. The inner layer is a sealing capsule, which is used to directly accommodate the phase change material. The sealing capsule is made of materials with good airtightness such as polymer film or metal foil. A thermal conductive layer is arranged between the sealing capsule and the protective shell. The function of the thermal conductive layer is to promote heat conduction between the phase change material and the water circulation pipeline, and can be made of materials such as high thermal conductivity graphite film, aluminum foil or carbon fiber braid. The introduction of the thermal conductive layer not only improves the efficiency of the phase change material in absorbing and releasing heat, but also helps to improve the thermal response speed.
[0092] In addition, the inner cavity of the sealing capsule is divided into multiple small chambers, each of which is equivalent to an independent unit. The design of this honeycomb structure is mainly to prevent the liquid phase change material from flowing in the capsule and keep it evenly distributed. At the same time, during the phase change process, the honeycomb structure can also effectively avoid the stress concentration caused by volume change, thereby extending the service life of the product.
[0093] The multi-layer composite structure design of the phase change capsule 1024 realizes efficient heat transfer between the phase change material and the water circulation pipeline. At the same time, the honeycomb sealed capsule structure ensures the uniformity and stability of the phase change material during the phase change process.
[0094] In one embodiment of the present invention, the water heating layer 102 is provided with a main energy storage area and a secondary energy storage area, the main energy storage area is located at a position corresponding to the human body trunk, and the secondary energy storage area is located at a position corresponding to the human body limbs, and a plurality of phase change capsules 1024 are respectively arranged in the main energy storage area and the secondary energy storage area, and the capacity of the phase change capsule 1024 in the main energy storage area is greater than the capacity of the phase change capsule 1024 in the secondary energy storage area.
[0095] That is to say, a phase change capsule 1024 with a relatively large capacity is arranged in the main energy storage area to provide a long-lasting temperature regulation capability for the trunk. The human trunk is the main part of the body where heat is dissipated, and the demand for temperature is relatively large. In contrast, the phase change capsule 1024 in the secondary energy storage area has a relatively small capacity and mainly plays a role in auxiliary temperature regulation.
[0096] Through this partition design, the phase change material reserves of the entire temperature control can be more reasonably allocated, fully meeting the differentiated temperature requirements of different parts of the human body, avoiding waste of resources, and improving energy efficiency. At the same time, the partition design also enhances the flexibility and refinement of temperature regulation, and can independently adjust the storage energy of each area according to different environments and usage scenarios to achieve temperature control management.
[0097] In one embodiment of the present invention, the temperature control mattress assembly 10 further includes a temperature regulating valve, which includes a two-way temperature control valve, which is provided on each of the sub-pipelines 1023 and is used to control the flow of hot water into and out of each of the sub-pipelines 1023. In practical applications, the controller 40 can control the opening of the two-way temperature control valve according to the body temperature data and the temperature data detected by the temperature sensing layer 103, thereby realizing the zoned temperature regulation of the temperature control mattress assembly 10, and meeting the differentiated temperature comfort requirements of the human body.
[0098] In one embodiment of the present invention, the water heating layer 102 is also provided with a backup heating unit, which includes a graphene heating film 105. The graphene heating film 105 is arranged above the phase change insulation unit for supplementary heating when the stored energy is insufficient.
[0099] In normal working mode, temperature control mainly relies on water circulation to heat the phase change insulation unit, thereby providing a suitable temperature environment for the human body. However, in some special cases, such as when the water supply is interrupted or the energy storage is insufficient, the phase change insulation unit cannot obtain sufficient heat supply. At this time, auxiliary heating can be provided by the backup heating unit. The graphene heating film 105 has an extremely high heating rate and heating uniformity, and can evenly heat the entire area in a very short time, avoiding local overheating.
