       BACKGROUND OF THE INVENTION  
       [0002]     Due to a longer average life expectancy in the whole world, home care for the aged has become a major social issue. If properly handled, this can save social costs and fully utilize social resources. Therefore, a home environment controlling system has become a major issue in today&#39;s health care. The home care system can relieve the burden of health care staff and stabilize the physiological and mental states of the aged.  
         [0003]     Moreover, environmental conditions are often major disease inducers. Therefore, the home care system can further be disposed in hospitals, hospice centers and even homes to build an environment suitable for patients and keep them away from pathogenic factors. The home care system detects and controls environmental factors (for example, temperature, humidity, etc.) that directly affect a person&#39;s physiological functions and also environmental factors (for example, illumination, loudness, etc.) that affect a person&#39;s mental states.  
         [0004]     If medical equipment and apparatuses, mechanical and electrical systems and sensors are integrated into a home care system, it&#39;s desired to have regulatory strategies of the system, which are based on the health information and environmental conditions, to create a health-promoting living environment for home care or disease management.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0015]     Referring to  FIG. 1 , the environment controlling system  100  of the present invention comprises at least a personal physiological measurement equipment  5  to measure the physiological information of the cared person, a central processing equipment  1  comprising at least an input/output interface  2 , a storage device  4  and an analytical unit  3 , at least an environment controlling equipment  6  that is connected to the input/output interface  2  of the central processing equipment  1  to regulate environmental conditions, at least an environment measurement equipment  7  that is connected to the input/output interface  2  of the central processing equipment  1  or the environment controlling equipment  6 , or is connected to input/output interface  2  and the environment controlling equipment  6  simultaneously to measure environmental information.  
         [0016]     The analytical unit  3  of the central processing equipment  1  of the environment controlling system  100  analyzes the cared person&#39;s physiological information measured by the personal physiological measurement equipment  5 , the environmental information measured by the environment measurement equipment  7 , and the health information stored in the storage device  4  via the input/output interface  2 , in order to decide an optimum environmental condition for the cared person. This optimum environmental condition is compared with the environmental information to obtain regulation information. Then the central processing equipment  1  can transmit the regulation information via the input/output interface  2  to the environment controlling equipment  6  to regulate the environmental conditions.  
         [0017]     The “physiological information” referred to in the present invention means the values of the cared person&#39;s physiological conditions that have been measured, converted, analyzed, computed, or recorded, and it includes but are not limited to the cared person&#39;s blood pressure, pulse, body temperature, respiration rate, brain waves, blood oxygenation or cardiac electrical signals.  
         [0018]     The “environmental information” referred to in the present invention means the values of the cared person&#39;s environmental conditions that have been measured, converted, analyzed, computed, or recorded, and it includes, but not limited to, air pressure, temperature, humidity, illumination, oxygen content, air cleanliness, wind speed or loudness.  
         [0019]     The “regulation information” herewith refers to the adjusting values of the environmental controlling equipments. The central processing equipment computes the adjusting values from optimum environmental conditions and environmental information, then the central processing equipment transforms the adjusting values into commands and transmits commands via the input/output interface to the environmental controlling equipment. Finally, the environmental controlling equipments execute the commands to adjust the environmental conditions, such as reducing the temperature or raise humidity.  
         [0020]     In the environment controlling system  100 , the storage device  4  stores the health information of the cared person. The “health information” referred to in the present invention includes the environmental factors that would induce discomfort or diseases to the cared person (for example, dust in the air, sudden changes or exceeding specific values of air temperature, air pressure, humidity, or loudness) and the environmental conditions suitable for the cared person&#39;s home care or treatment (for example, air pressure, temperature, humidity, illumination, oxygen content, air cleanness, wind speed or music within a specific range.)  
         [0021]     When the embodiment of the central processing equipment  1  of the environment controlling system  100  is configured as a computer, the input/output interface  2  means an interface connected the computer to other hardwares in the scope of information engineering for information transmission between other equipments in the environment controlling system  100  and the central processing equipment  1 . The input/output interface  2  can be a fixed interface connected to a motherboard or can be an external interface detachable from the motherboard. When the input/output interface  2  is an external interface, it can be configured as a remote end of the analytical unit  3  corresponding to the environment controlling system  100  so as to facilitate the exchange and transmission of information between the central processing equipment  1  and the personal physiological measurement equipment  5 , and between the environment controlling equipment  6  and the environment measurement equipment  7 . In summary, the input/output interface  2 , the storage device  4  and the analytical unit  3  of the present invention can be disposed at the same or different geographical locations. For example, the input/output interface  2  can be disposed at the location (for example, home) of the cared person, whereas the storage device  4  or the analytical unit  3  can be disposed at another far-distant location (for example, hospitals, health care centers, hospice centers, etc.) The aforementioned three units can be connected via a far-distant or near-distant wireless or cable means. The embodiment of the input/output interface  2  of the present invention includes, but not limited to, the mechanical and electrical hardware technology that employs input/output interfaced (I/O interface), parallel ports, USB interface, visual interfaces, infra-red interfaces, cable transmission interfaces, wireless transmission interfaces and Bluetooth interfaces to transmit analog/digital information. In other words, the aforementioned interfaces can be employed to transmit information for connecting the central processing equipment  1  to the environment controlling equipment  6 , the personal physiological measurement equipment  5  and the environment measurement equipment  7  of the environment controlling system  100  of the present invention. The analytical unit  3  is generally known as the hardware and software for computer computation and operation, with hardware including a central processing unit (CPU), memory, south/north bridge for hardware control, electric circuit board, etc. and with software including platform programs, for example, Windows Operating System or Linux and an environment controlling program installed on the system platform. The storage device  4  can be a data storage medium for computer, for example, a hard disk drive.  
         [0022]     The environment controlling system  100  can further comprise an information input device  8  as shown in  FIG. 2 . The information input device  8  is connected to the input/output interface  2  and can be employed to input or modify the information into the central processing equipment  1 . In some embodiments, when the personal physiological measurement equipment  5  is not directly connected to the input/output interface  2 , the physiological information obtained from the personal physiological measurement equipment  5  can be input into the central processing equipment  1  via the information input device  8 . The information input device  8  can also be employed to modify the health information stored in the storage device  4 . When the central processing equipment  1  is configured as a computer, the common information input device  8  is a keyboard or a mouse.  
         [0023]     The “personal physiological measurement equipment” referred to in the present invention includes a thermometer, sphygmomanometer, pulsimeter, electroencephalograph, pulse oximeter, spirometer or cardiograph employed to obtain the cared person&#39;s physiological information. In some embodiments, the personal physiological measurement equipment is not connected to the central processing equipment, and the measured physiological information can be manually input into the central processing equipment via the information input device. In a preferred embodiment, the personal physiological measurement equipment is connected to the input/output interface such that the central processing equipment can automatically obtain physiological information. Moreover, the “personal physiological measurement equipment” can be directly in contact with the cared person to measure related physiological information or indirectly measure the cared person&#39;s physiological information, for example, infrared sensing of the cared person&#39;s temperature, etc.  
         [0024]     The “environment controlling equipment” referred to in the present invention includes hardware such as pneumatic controllers, air conditioners/heaters, humidity controllers, lighting fixture, oxygen machines, air purifiers, fans or music option and players that can be employed to regulate environment conditions. The hardware is connected to the central processing equipment and can receive the regulation information transmitted from the central processing equipment via the input/output interface, thereby starting or stopping the equipment on the basis of the regulation information.  
         [0025]     The “environment measurement equipment” referred to in the present invention includes hardware such as indoor barometers, thermometers, hygrometers, photometers, oxygen analyzers, air analyzers, wind gauges, loudness gauges, etc., employed to measure environmental conditions. In some embodiments, the environment measurement equipment can be connected to the input/output interface such that the analytical unit can directly obtain the environmental information measured by the environment measurement equipment. Whereas in some embodiments, the environment measurement equipment can be connected to the environment controlling equipment, and the latter can be operated on the basis of the environmental information measured by the environment measurement equipment in order to keep the environmental conditions constant.  
         [0026]     The storage device  4  of the environment controlling system  100  of the present invention can further store the health, physiological, or environmental information measured by the environment measurement equipment at different time points to act as the basis for the regulation of the environment controlling program referred to in the analytical unit  3 .  
         [0027]     Referring to  FIG. 3 , the environment controlling system  100  of the present invention can further include a remotely control equipment  9  that is connected to the input/output interface  2  of the central processing equipment  1 . When the central processing equipment  1  is configured as a server that allows the login of the remotely control equipment  9 , the remotely control equipment  9  can read the health, physiological or environmental information stored in the storage device  4  at any time or transmit the health, physiological or environmental information stored in the storage device  4  to the remotely control equipment  9  according to the schedule arranged by the central processing equipment  1 . Also, the remotely control equipment  9  can regulate the environment controlling program of the analytical unit  3  or directly determine regulation information to directly regulate the environmental conditions.  
         [0028]     The “connection” referred to in the present invention means the transmission of information among equipment by means of cable or wireless transmission modules. Cable transmission modules include conventional bus lines, signal lines, cable network, telephone wires and optical fibers for analog or digital signal transmission. The wireless transmission modules include wireless transmission technology, such as HomeRF, the Bluetooth technology, infrared rays and IEEE 802x.  
         [0029]     Therefore, the central processing equipment of the environment controlling system of the present invention can be independently disposed outside the living space of the cared person and, via cable or wireless transmission technology, is connected to the personal physiological measurement equipment, environment controlling equipment and environment measurement equipment that are all disposed in the living space of the cared person.  
         [0030]     The personal physiological measurement equipment, environment controlling equipment and environment measurement equipment disposed in the living space of the cared person can be connected to the input/output interface corresponding to one or a plurality of equipment connections of the central processing equipment. In other words, the personal physiological measurement equipment, environment controlling equipment and environment measurement equipment can be configured in the same or different connections so as to connect to the central processing equipment, via the corresponding input/output interface.  
         [0031]     The present invention provides the environment controlling method, comprising the steps of providing a central processing equipment, at least a personal physiological measurement equipment, at least an environment controlling equipment, and at least an environment measurement equipment, wherein the central processing equipment comprises an analytical unit, an input/output interface and a storage device. The central processing equipment is connected to the environment controlling equipment and the environment measurement equipment via the input/output interface; the storage device stores the health information of the cared person. Physiological and environmental information can be obtained by means of the personal physiological measurement equipment and the environment measurement equipment. The analytical unit in the central processing equipment decides an optimum environmental condition on the basis of the physiological, environmental and health information, and then compares the optimum environmental condition with the environmental information to obtain regulation information. The central processing equipment transmits the regulation information via the input/output interface to the environment controlling equipment that regulates environmental conditions on the basis of the regulation information. The terms referred to in the aforementioned method are explained and defined as set forth in the system.  
         [0032]     The “optimum environmental condition” referred to in the system or method thereof is determined by the environment controlling program of the analytical unit, wherein the environment controlling program comprises a plurality of parameters in connection with the critical values of the cared person&#39;s physiological information or environmental information, for example, the upper limits or the lower limits of the cared person&#39;s heartbeats, respiration rates, blood pressure, temperature, and humidity. When the values of the cared person&#39;s physiological information or environmental information exceed the configured critical values, the environment controlling program will decide an optimum environmental condition on the basis of physiological, environmental and health information. In other words, the optimum environmental condition can be both static and dynamic on the basis of physiological, environmental and health information and the analysis of environmental conditions.  
         [0033]     It is to be understood that the following examples of the present invention should not be based to restrict the invention, and that all equivalent modifications and variations made without departing from the intent and import of the following descriptions of the examples should be included in the following claims.  
       Embodiment  
     Environmental Control of Bronchial Asthma-affected Patients  
       [0034]     Among respiratory diseases, bronchial asthma is a commonest but hard to be completely cured and disturbing chronic disease. The pathogen factor of bronchial asthma is primarily allergic reactions (approximately 75%) including dust in the air, pollens, animal hairs and peeling skin, some food, drugs and cosmetics. Other factors include sudden changes in polluted air, air temperature, humidity or air pressure or respiratory tract inflammation.  
         [0035]     The symptoms of bronchial asthma at the onset of the disease are primarily sudden breakout, heightened heart beats, dry cough, difficulties in breathing, longer inhale time than exhale time, and special wheezing sounds. During care or treatment, the control of environmental factors (such as air cleanliness, air temperature and humidity) is very important to the bronchial asthma-affected patients. In case of changes to the aforementioned environmental factors, bronchial asthma symptoms develop, and abnormal changes happen to the patients&#39; heartbeats and respiration.  
         [0036]     The environment controlling system or method of the present invention can be applied to the environmental control of bronchial asthma-affected patients during care or treatment in order to help them speed up recovery, reduce the incidence or alleviate the conditions of the disease.  
         [0037]     Referring to  FIG. 4 , personal health information is input and saved into the storage device  4  of the central processing equipment  1 . Health information includes the environmental factors (such as exceeding specific values of dust in air, pollens, animal hairs and peeling skin, and sudden changes or exceeding specific values of air temperature, humidity or air pressure) that stimulate the incidence and the range of environmental conditions suitable for the patient&#39;s home care or treatment (such as room temperature within 23-27° C., 40-60% humidity, etc.)  
         [0038]     Then the patient&#39;s heartbeats and respiratory rate are measured by a pulsimeter  10  and a spirometer  11 , and an air detection device  12 , a thermometer  13  and a hygrometer  14  are employed to monitor air cleanliness, air temperature and humidity, respectively. The pulse rate of a normal person lies between 60 and 100, and the respiratory rate lies between 8 and 20. The pulsimeter  10  and the spirometer  11  are employed to measure the person&#39;s heartbeat and respiratory rate before the onset of the disease in order to establish the relationship of the patient&#39;s heartbeat and respiratory rate before the onset of the disease and physiological durations (including sleeping, awakening, during activity, etc.) and store the aforementioned information in the storage device  4  as the basis for comparison.  
         [0039]     When abnormal heartbeats and respiratory rate are found (for example, significantly heightened heartbeats or respiratory rate in comparison with the heartbeats and respiratory rate at the same physiological duration prior to the onset of the patient&#39;s disease), the environment controlling program of the analytical unit  3  of the central processing equipment  1  will compare the parameters (such as the dust particles, air temperature and humidity) with the personal health information stored in the storage device  4  to decide an optimum environment for the patient&#39;s physiological conditions and decide a regulation strategy after comparing it with the existing environmental conditions, thereby starting the environment controlling equipment (such as a humidity controller  15 , air conditioner/heater  16 , air purifier  17  as shown in  FIG. 4 ) to alleviate the patient&#39;s discomfort (such as heightened heartbeats and respiratory rate.) When the system is regulating the environment, it simultaneously monitors and analyzes the patient&#39;s physiological reactions (for example, heartbeats and respiratory rate) as the basis for further regulation so as to achieve an optimum environment for the patient&#39;s comfort. For example, when sudden changes in the patient&#39;s respiratory rate are found to be caused by an increase in pollen particles, the central processing equipment  1  will start the air purifier  17  to reduce the pollen particles in air. If the analysis results of the analytical unit  3  show that the patient&#39;s abnormal physiological conditions are caused by the combined effects of a sudden rise in air temperature and an increase in pollen particles, the central processing equipment  1  will simultaneously start the air-conditioner/heater  16  and the air purifier  17  to regulate the environment and patient care. In summary, the regulation information can start the operations of a single environment-controlling configuration for an environment controlling equipment or a multiple environment-controlling configuration for a plurality of environmental equipments on the basis of the importance of environmental parameters.  
         [0040]     In summary, by integrating medical equipment and apparatuses, mechanical and electrical systems, sensors, and controllers, optimum environmental controlling strategies for patients can be estimated by algorithms on the basis of health information and environmental conditions, to create a health-promoting living environment for home care or disease management and keep away from the environmental factors that induce diseases.
