Description
Technical Field
The utility model relates to a technical field of physiological signal passes collection system and system, concretely relates to many physiological signal sensing device of fusion, detection device and many physiological signal acquisition method.
Background
In the prior art of physiological signal acquisition, corresponding physiological signal sensors or physiological signal acquisition devices are generally arranged separately according to different types of physiological signals. All electrode connecting wires for measuring electrocardio are arranged in an electrocardio cable of the independent electrocardio signal acquisition device. All electrode connecting wires for measuring blood oxygen are arranged in the blood oxygen cable of the independent blood oxygen signal acquisition device. An electrode connecting wire for measuring body temperature is arranged in a body temperature cable of the independent body temperature signal acquisition device.
Due to the design, the accessories of the multi-parameter monitoring device are various in types and extremely complex to store. To measure three physiological parameters, 3 different accessories must be configured; that means, will accomodate multiple annex respectively, not only increased the degree of difficulty and the work load of accomodating, to using, need fix the signal acquisition device of a plurality of different grade types respectively on different body parts.
For multi-parameter monitoring equipment, in order to adapt to different accessories, cable interfaces for measuring various physiological parameters need to be respectively arranged on the multi-parameter monitoring equipment, for example, a blood oxygen cable interface, an electrocardio cable interface and a body temperature cable interface need to be respectively arranged on a shell of the multi-parameter monitoring equipment; such multiple interface arrangements increase the cost of device design and implementation.
For electrocardiographic measurement, at least three electrode connecting wires of an electrocardiograph cable are needed, so in an independent electrocardiographic signal acquisition device, at least three independent electric connecting wires need to be separated from a main electrocardiograph cable for electric connection with different electrocardiograph electrodes, and because the positions of the electrocardiograph electrodes are different, the lengths of the three independent electric connecting wires also have corresponding requirements, so that the electrocardiograph cables are more branched, and the storage becomes more troublesome.
As shown in fig. 1, in the prior art, when multi-parameter monitoring is performed, various physiological signal sensors are connected schematically. As shown in fig. 1, for blood oxygen measurement, a separate blood oxygen signal sensing device is provided; for body temperature measurement, an independent body temperature signal sensing device is arranged; an independent electrocardiosignal sensing device is arranged for electrocardio measurement; in order to be connected with three independent physiological signal sensing devices, three interfaces are arranged on the side surface of the multi-parameter monitoring equipment, and the three interfaces are respectively connected with one physiological signal sensing device.
As shown in fig. 1, in order to measure the electrocardiographic signals, a plurality of electrocardiographic electrode connection points are arranged in the electrocardiographic signal sensing device, and the plurality of electrocardiographic electrode connection points need to be arranged at different parts of the human body, which means that the electrocardiographic signal sensing device must have a plurality of cables with different lengths and long enough, one end of each cable is connected with the electrocardiographic electrode attached to the surface of the human body, and the other end of each cable is gathered by a concentrator and then enters the multi-parameter monitoring device through the cable for signal processing.
In the prior art, there is a device for integrating cables for measuring various physiological signals, such as a multi-parameter cable splitter (CN201898306U), in which a plurality of independent electrocardiograph cables are connected to a main body of a multi-parameter monitor after being switched by the multi-parameter cable splitter.
In the integration, when the multi-parameter monitor is used, a plurality of independent electrocardiosignal acquisition devices are still needed at the patient end, namely, electrocardioelectrodes are connected with electrocardio cables; the blood oxygen probe is connected with the blood oxygen cable, and the body temperature probe is connected with the body temperature cable. The electrode connecting end of the electrocardio cable cannot be integrated with the blood oxygen probe or the body temperature probe; for the object monitored by the multi-parameter monitoring device, the electrocardio-electrode, the blood oxygen probe and the body temperature probe are required to be fixed at different positions respectively.
For a monitored patient, the chest is usually attached to a plurality of electrocardio electrodes, a blood oxygen probe is clamped on fingers, and a body temperature electrode is fixed at a specific position; it is extremely uncomfortable for the patient to fix or attach the electrodes and connect them at a number of different locations; however, when the cables move slightly, the cables are easy to pull each other, which affects the connection state of each cable; the experience of the patient in the measuring process is very poor. And a plurality of single electrocardiosignal connecting wires connected with the electrocardio-electrodes are easy to be pulled in use and are easier to be damaged than the cable at the rear end of the concentrator.
It is also necessary for the nurse to search for the proper body part of the patient to fix each physiological parameter acquisition device. Electrocardio-electrodes are usually attached to the chest and four limbs; blood oxygen probes are typically clamped or affixed to the extremities of the body; a plurality of positions and different signal acquisition devices are connected, so that the experience of a patient in the measuring process is very poor, and the workload of fixing the plurality of signal acquisition devices by a nurse is increased. Fixing or attaching electrodes at multiple different locations and connecting them is uncomfortable and inefficient. A plurality of single electrocardiosignal connecting lines are contacted with a human body, so that the workload of disinfection is increased when a user is replaced.
In order to reduce the inconvenience brought to the design, use and storage of the multi-parameter monitoring device by the cables of a plurality of signal acquisition devices, especially to improve the experience of patients and the use efficiency of nurses, a revolutionary solution is urgently needed. However, since the birth of the monitoring device, people seem to be used or adapted to the way of separately and independently arranging the physiological signal acquisition devices, and no solution which can really improve and promote the experience of patients and the use efficiency of nurses is found.
