技术领域technical field

本发明涉及一种生理信号测量装置，特别是指一种由外部电子装置提供电源、显示与运算服务，并以一般通讯协议的连接端口接收的生理信号测量装置。The invention relates to a physiological signal measuring device, in particular to a physiological signal measuring device which is provided with power supply, display and calculation services by an external electronic device and received through a connection port of a general communication protocol.

背景技术Background technique

随着物质生活的富裕，现代人罹患文明病的机会大幅提升，根据研究报告指出，四十岁以上的成年人其高血压罹患率已高达五分之一。而高血压会造成对脑部、心脏及肾脏的影响，例如引起脑部血管硬化而易使血管破裂或阻塞造成中风，或引起心室肥大、心脏衰竭、狭心症，严重者因冠状动脉栓塞而致死，以及引起肾脏动脉硬化、尿毒症等疾病。因此，做好健康管理应先勤于量测血压，以对自己的血压了若指掌。With the affluence of material life, the chances of modern people suffering from civilized diseases have been greatly increased. According to research reports, the incidence rate of hypertension among adults over the age of 40 is as high as one-fifth. High blood pressure can affect the brain, heart and kidneys, such as hardening of the blood vessels in the brain, which can easily cause blood vessel rupture or blockage, resulting in stroke, or cause ventricular hypertrophy, heart failure, angina, and severe cases due to coronary embolism. Fatal, and cause kidney arteriosclerosis, uremia and other diseases. Therefore, to do a good job in health management, you should be diligent in measuring blood pressure first, so as to know your own blood pressure well.

市售的血压计本身体积大，且一般需有较重且体积较大的配备，其功能一般包含量测、运算与显示。由于需要运算与显示，所以以电源为例，可利用直流电，例如干电池，需要配备一定数量的电池方能提供运算与显示所需的电力，如此将造成血压计的体积与重量增加。如可同时利用交流电者，则需要配备体积庞大的电压器，造成携带上的不便。此外，由于同时具备显示与运算功能，血压计本身的体积与重量均会增加，亦造成血压计本身的成本增加。另一方面，科技目新月异，设计出许多功能整合的计算机、个人数字助理与移动通讯装置，例如手机。上述大部分的电子装置由于须实现其功能，因此皆具有运算与显示的功能，并且具备电源供应元件。Commercially available sphygmomanometers are bulky, and generally require heavy and bulky equipment, and their functions generally include measurement, calculation, and display. Since calculation and display are required, taking the power supply as an example, direct current can be used, such as dry batteries, and a certain number of batteries are required to provide the power required for calculation and display, which will increase the volume and weight of the blood pressure monitor. If the AC power can be used at the same time, it needs to be equipped with a bulky voltage converter, which causes inconvenience in carrying. In addition, due to the simultaneous display and calculation functions, the volume and weight of the sphygmomanometer itself will increase, which also increases the cost of the sphygmomanometer itself. On the other hand, technology is changing rapidly, and many integrated computers, personal digital assistants and mobile communication devices, such as mobile phones, have been designed. Most of the above-mentioned electronic devices have computing and display functions and power supply components because they need to realize their functions.

比较一般血压计与一般计算机、个人数字助理与移动通讯装置时可以发现，两者的若干功能元件似乎重复。当生理信号测量装置的设计随着科技的进步，朝向可携带的轻薄短小的方向时，如何减少生理信号测量装置的元件但维持其基本功能便成为重要的课题之一。此外，使用时的方便性与使用后数据的可用性也为设计生理信号测量装置时所需考量的因素之一。When comparing a general sphygmomanometer with a general computer, a personal digital assistant and a mobile communication device, it can be found that some functional elements of the two seem to be duplicated. When the design of the physiological signal measuring device is moving towards a portable, light, thin and small direction with the advancement of technology, how to reduce the components of the physiological signal measuring device while maintaining its basic functions has become one of the important issues. In addition, the convenience of use and the availability of data after use are also one of the factors to be considered when designing a physiological signal measurement device.

The physiological signal measurement device 10 has a buffer unit 102 , a signal detection unit 103 , a signal conversion unit 104 and a connection port 105 .

In one embodiment, the signal conversion unit 104 includes an analog /Digital converter (A/D converter). The connection port 105 is connected to a wired signal line 30 (for example, in the form of a universal serial bus), a signal detection unit 103 and a signal conversion unit 104, which receives a signal transmitted by thewired signal line 30 to provide the signal detection unit 103 and the signal conversion unit 104 The power required for execution is output to an external electronic device 20 through thewired signal line 30 to output the digital physiological signal of the signal conversion unit 104 . It should be noted that the connection port 105 can be a universal serial bus port, or a connection port that conforms to a general communication protocol, and has a connection with a specific controller (in this embodiment, a USB controller) at either end of the connection port.

根据本发明的精神之一，是利用一般外部电子装置20既有的功能或元件，例如电源或处理器等，支持生理信号测量装置10，以减少生理信号测量装置10的体积与成本。生理信号测量装置10可以是血压计、血氧计、体温计或血糖计或上述功能的结合，其可固定于手臂、手腕或手指上进行量测。外部电子装置20，例如个人计算机、个人数字助理或移动通讯装置等，其一般皆具有电源单元201、运算处理单元202、储存单元203、显示单元204与一连接端口205。连接端口205可以通过有线信号线30与生理信号测量装置10的连接端口105连接。其次，外部电子装置20的电源单元201可通过有线信号线30将电力，例如5伏特的电力，传送给生理信号测量装置10。再者，外部电子装置20的运算处理单元202亦可有线信号线30下达执行功能的指令给生理信号测量装置10的信号检测单元103以执行感测的步骤。此外，外部电子装置20的运算处理单元202，例如一中央处理器(CPU)更可通过有线信号线30接收生理信号测量装置10的数字生理信号并进行运算处理后显示于显示单元204，例如液晶显示屏，并且储存于储存单元203，例如内存中。According to one spirit of the present invention, the existing functions or components of the general external electronic device 20 , such as a power supply or a processor, are used to support the physiological signal measurement device 10 , so as to reduce the volume and cost of the physiological signal measurement device 10 . The physiological signal measuring device 10 can be a blood pressure meter, an oximeter, a thermometer, a blood glucose meter or a combination of the above functions, and it can be fixed on an arm, wrist or finger for measurement. The external electronic device 20 , such as a personal computer, a personal digital assistant or a mobile communication device, generally has a power supply unit 201 , an operation processing unit 202 , a storage unit 203 , a display unit 204 and a connection port 205 . The connection port 205 can be connected to the connection port 105 of the physiological signal measurement device 10 through awired signal line 30 . Secondly, the power supply unit 201 of the external electronic device 20 can transmit power, such as 5 volts of power, to the physiological signal measuring device 10 through thewired signal line 30 . Moreover, the operation processing unit 202 of the external electronic device 20 can also issue an instruction to perform functions to the signal detection unit 103 of the physiological signal measurement device 10 through thewired signal line 30 to perform the sensing step. In addition, the calculation and processing unit 202 of the external electronic device 20, such as a central processing unit (CPU), can receive the digital physiological signal of the physiological signal measurement device 10 through thewired signal line 30 and display it on the display unit 204 after calculation and processing, such as a liquid crystal display screen, and stored in the storage unit 203, such as memory.

举例来说，生理信号测量装置10的信号检测单元103包含一泵模块与传感器模块(图上未示)。当利用有线信号线30连接两连接端口105、205后，由外部电子装置20下达指令传送给泵模块开始打气至一预设情形且逐渐放气时，由传感器模块开始感测一连串的血压脉动。生理信号测量装置10对于此一血压脉动的信号仅进行获取与转换成数字生理信号后，即通过有线信号线30将数字生理信号交给外部电子装置20进一步处理、分析与显示。根据上述，外部电子装置20必须具有若干基本元件才可执行所具备的功能，但生理信号测量装置10则尽可能短小、轻薄且价格更实惠。根据一实施例，利用万用序列总线端口与万用序列总线线(USB cab1e)的组合连接生理信号测量装置10与一般外部电子装置20，以外部电子装置20既有的元件提供生理信号测量装置10所需的电力与运算与显示服务，如此可以大幅减少生理信号测量装置10的成本与体积，且生理信号测量装置10所感测的生理信号可进一步储存于外部电子装置20中以供后续之用。For example, the signal detection unit 103 of the physiological signal measurement device 10 includes a pump module and a sensor module (not shown in the figure). After connecting the two connection ports 105, 205 with thewired signal line 30, the external electronic device 20 sends an instruction to the pump module to start inflating to a preset state and gradually deflate, and the sensor module starts to sense a series of blood pressure pulses. The physiological signal measurement device 10 only acquires and converts the blood pressure pulsation signal into a digital physiological signal, and then sends the digital physiological signal to the external electronic device 20 through thewired signal line 30 for further processing, analysis and display. According to the above, the external electronic device 20 must have several basic components to perform its functions, but the physiological signal measuring device 10 should be as short as possible, thinner and more affordable. According to one embodiment, the physiological signal measurement device 10 is connected to the general external electronic device 20 by using a combination of a USB port and a USB cable (USB cab1e), and the physiological signal measurement device is provided with the existing components of the external electronic device 20. 10 required power and computing and display services, so that the cost and volume of the physiological signal measurement device 10 can be greatly reduced, and the physiological signals sensed by the physiological signal measurement device 10 can be further stored in the external electronic device 20 for subsequent use .

图2所示为根据本发明的另一实施例实现一生理信号测量装置的方块系统示意图。与图1的实施例相异之处在于，生理信号测量装置10进一步包含一电力储存单元106，例如一储存电容，当生理信号测量装置10通过连接端口105从有线信号线30接收外部电子装置20所提供的电力时，也可对于电力储存单元106进行充电。如此一来，万一外部电子装置20因不可抗拒的因素而突然中断提供电力时，生理信号测量装置10仍可通过电力储存单元106所储存的电力作为执行感测所需的电力。FIG. 2 is a schematic diagram of a block system implementing a physiological signal measuring device according to another embodiment of the present invention. The difference from the embodiment of FIG. 1 is that the physiological signal measurement device 10 further includes a power storage unit 106, such as a storage capacitor, when the physiological signal measurement device 10 receives the external electronic device 20 from thewired signal line 30 through the connection port 105 When the supplied power is supplied, the power storage unit 106 can also be charged. In this way, in case the power supply of the external electronic device 20 is suddenly interrupted due to irresistible factors, the physiological signal measurement device 10 can still use the power stored in the power storage unit 106 as the power required for sensing.

根据上述，本发明的精神所实现的生理信号测量装置可以是血压计、体温计或血糖计，其具有符合一般通讯协议的连接端口作为输出入端口，利用此连接端口接收所需的电力与输出所感测的生理信号，则生理信号测量装置本身可以省略电源、处理运算与显示的设计，具有轻巧与降低成本的优点。再者，由生理信号测量装置所感测的生理信号，能够实时传输至一般的外部电子装置上，使用者可直接通过外部电子装置处理生理信号并显示，且此些生理信号的后续利用将更具弹性。According to the above, the physiological signal measuring device realized by the spirit of the present invention can be a blood pressure monitor, a thermometer or a blood glucose meter, which has a connection port conforming to a general communication protocol as an input and output port, and utilizes this connection port to receive the required power and output the sensor. If the physiological signal is measured, the physiological signal measuring device itself can omit the design of power supply, processing operation and display, which has the advantages of lightness and cost reduction. Furthermore, the physiological signals sensed by the physiological signal measuring device can be transmitted to general external electronic devices in real time, and the user can directly process and display the physiological signals through the external electronic devices, and the subsequent utilization of these physiological signals will be more convenient. elasticity.

上述具体实施方式仅用以说明本发明，而非用以限定本发明。The above specific embodiments are only used to illustrate the present invention, but not to limit the present invention.
