The utility model provides a pain stimulus device which comprises a micro-injection pump, an index acquisition terminal, a pain assessment terminal, a feedback unit and a controller. The micro-injection pump is used for injecting hypertonic saline into a human body, the human body is stimulated to feel persistent pain, the index acquisition terminal is used for acquiring a subjective pain value of the human body in real time, the pain assessment terminal is connected with the index acquisition terminal, analyzes and assesses the pain according to the subjective pain value of the human body and predicts an assessed pain value at a next moment, the feedback unit is connected with the pain assessment terminal and feeds the assessed pain value to the controller, and the controller is connected with the feedback unit and the micro-injection pump and controls the injection speed of the micro-injection pump according to the assessed pain value. The pain stimulus device has the advantages that the injection speed of the micro-injection pump is regulated, so that the human body feels the constant and persistent pain to an expected degree, research and simulation for pain are greatly facilitated, the accuracy of the research for pain is improved, and a great improvement effect for treating pain is realized.
Description
Technical field
This utility model relates to a kind of armarium, relates in particular to a kind of pain stimulating device.
Background technology
Pain is as one of the most general clinical symptoms, and is little of to patients ' life quality, all brought a lot of negative effects to patient and family members' health greatly.Treatment pain, impression and the variation of human body under the mechanism that necessary research pain produces and different pain degree.
At present, by stimulating human body to produce pain, the change of then observing human body behavior and manner judges pain degree to researcher mostly, research pain.But pain is a kind of offending subjective feeling and emotional experience, different from other coenesthesias (as audition, vision, olfactory sensation etc.), pain is subject to the impact of psychology and society factor to a great extent, there is no corresponding physical and chemical index, Pain Cognition is a subjective process, so method or technology are not measured pain effectively and accurately clinically.Pain visual imitation assessment VAS(VisualAnalog Scale) and types of facial makeup in Beijing operas method (The Faces pain Rating Scale) method of measuring in the world at present pain intensity has two kinds:, the former is judged the pain degree of oneself by patient, then delineates out corresponding mark; The latter delineates out the corresponding types of facial makeup in Beijing operas by the doctor according to patient's facial expression.The common shortcoming of these two kinds of methods is: patient's educational level, understandability to the bearing the factors such as degree patiently and all can have a huge impact measurement result of pain, thereby make result objective not, accurate.Simultaneously, different people has different experience to pain, different judgements, and subjectivity is strong.The difficulty that pain intensity is measured and the subjectivity characteristics of pain make the lasting constant pain that is difficult to make expected degree, thereby bring very big inconvenience for research pain.
The utility model content
Based on this, being necessary the problem that is difficult to make the lasting constant pain of expected degree for above-mentioned provides a kind of pain stimulating device that can make the lasting constant pain of expected degree.
a kind of pain stimulating device comprises micro-injection pump, index selection terminal, pain Assessment terminal, feedback unit and controller, described micro-injection pump is used for to human injection's hypertonic saline, stimulate human body to produce constant pain, described index selection terminal is used for the subjective pain value of Real-time Obtaining human body, described pain Assessment terminal is connected with described index selection terminal, pain value subjective according to human body carried out assessment and analysis to pain, predict next pain Assessment value constantly, described feedback unit is connected with described pain Assessment terminal, the pain Assessment value is fed back to described controller, described controller is connected with micro-injection pump with described feedback unit, control the injection speed of described micro-injection pump according to the pain Assessment value.
Therein in embodiment, shown in micro-injection pump controlled by USB or RS232 serial port protocol.
Therein in embodiment, shown in the micro-injection pump minimum injection rate be 0.1UL/min, the syringe of compatible 5-50ML specification.
Therein in embodiment, shown in the index selection terminal obtain the subjective pain value of subjects by pain visual imitation assessment, described pain Assessment terminal is by carrying out time series modeling to subjective pain value, build autoregression model, find the solution the coefficient of autoregression model, predict next pain Assessment value of subjects constantly.
In embodiment, described index selection terminal realizes pain visual imitation assessment by the form of animation therein.
In embodiment, described pain stimulating device also comprises with the pain Assessment terminal and being connected, and is used for showing the display terminal of pain Assessment value therein.
Above-mentioned pain stimulating device, produce constant pain to human injection's hypertonic saline, the subjective pain value of Real-time Obtaining human body is carried out assessment and analysis to pain, predict next moment pain Assessment value and feed back to controller, controller is controlled the injection speed of micro-injection pump according to the pain Assessment value, thereby regulate the injection speed of micro-injection pump, obtain the constant and lasting pain of expected degree, research and simulation to pain have greatly been facilitated, improve the accuracy of pain research, played great impetus for treatment pain.
