Embodiment
Below with reference to accompanying drawings the embodiment of the robot system for ward data acquisition of the present invention is described in detail.
Need heavier by the general state of an illness of the patient nursed to ward, their health needs to be monitored in real time, and such as colour of skin situation of change and body posture situation, meanwhile, need to install the physiological index of some monitors to patient and gather.
Hospital is in order to complete patient inspection and monitor digital independent two tasks, normally take the method that nurse makes an inspection tour for a long time, the doctor in charge regularly checks, but the doctor in charge can be arranged the task of paying a home visit, nurse can not accomplish free of discontinuities monitoring in 24 hours, therefore, does not still realize the patient care of all the period of time, patient still can be absorbed in some period the difficult situation that nobody correlates, this problem, instant hospital drops into many manpowers again, also cannot obtain actual solution.
In order to depart from this predicament, some hospitals make an effort from equipment, such as build the hardware platform that more patient nurse is mutual, for when patient feels uncomfortable, timely nurse call comes to nurse, although this mode plays certain positive role, but, for severe case, owing to taking care of oneself, still the action mutual with nurse cannot be performed.
For above-mentioned deficiency; the present invention has built a kind of robot system for ward data acquisition; high-precision image acquisition and recognition technology is adopted to complete patient inspection and these two tasks of monitor digital independent; adopt wireless communication technology to ensure that robot system and nurse guard the two-way communication of platform; tour line technology is adopted to guarantee that robot system accurately moves to each image data point place in ward; thus in the mode of robot device's automatic monitoring; alleviate the task amount of medical personnel, improve care quality and the efficiency of patient.

In addition, ward is hospital for patient that disease condition is comparatively serious provides the place of nursing and treatment, generally be arranged near hospital outpatient department, it is indoor to strengthen monitoring and nursing that wherein more serious seriously ill patient also can be arranged into Intensive Care Therapy, ensures the therapeutic quality to patient and effect.
Intensive care unit, also known as intensive care unit, is called for short ICU.Monitoring and the treatment of critical illness are clinical specialities of rising in recent years, aim is for life-threatening acute severe patient provides technology and high-quality medical services, namely to the patient of severe crisis carry out physiological function monitoring, life support, prevent and treat complication, promote and accelerate the rehabilitation course of patient, this is a kind of higher level medical services after continuous recovery, is the inexorable trend of social modernization and development of medical sciences.In recent years; along with the continuous progress of high and new technology; multiple detection and support equipment are widely used in clinical, the universal and specification in ICU ward, and people are also perfect gradually to the understanding of life physiological function; therefore; improve the support to exhaustion organ and protective capability, the salvage success rate of critical grave illness is significantly improved, the patient of many severe crisis is in proper intensive care and under giving meticulous treatment; spend the moment the most difficult in life, and move towards rehabilitation gradually.Meanwhile, also drive and facilitate progress and the development of other clinical specialities.
In addition, image recognition, refers to and utilizes computing machine to process image, analyze and understand, to identify the target of various different mode and the technology to picture.During general industry uses, adopt industrial camera pictures taken, and then utilize software to do further identifying processing according to picture ash jump.
Image recognition may be based on the principal character of image.Each image has its feature, and as alphabetical A has a point, P has a circle and there is individual acute angle etc. at the center of Y.The research dynamic to eye during image recognition shows, sight line always concentrates in the principal character of image, and namely concentrate on the place of the maximum or contour direction flip-flop of image outline curvature, the quantity of information in these places is maximum.And the scanning route of eyes also always forwards to another feature from a feature successively.As can be seen here, in image recognition processes, perceptual mechanism must get rid of the redundant information of input, extracts crucial information out.In mankind's image identification system, often could to be realized by the Information procession of different levels the identification of complicated image.For the figure be familiar with, owing to having grasped its principal character, he will be used as a unit and identify, and no longer note his details.This overall unit be made up of the unit material isolated is called chunk, and each chunk is simultaneously perceived.In the identification of written material, people not only can form a chunk unit such as the stroke of a Chinese character or radicals, and can the word often together occurred or phrase in groups block unit identified.
Adopt the robot system for ward data acquisition of the present invention, cover period narrow range for existing ward NM, need the technical matters of a large amount of artificial work, introduce targetedly image acquisition and image recognition technology to the patient in ward with the related data of instrument gathers and accurate profile identification, and provide alarm mechanism when data exception, substitute traditional manual monitoring pattern with machine monitors pattern, improve the intelligent level of ward nursing.
