[specific embodiment]
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by the specific embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of pain stimulation device.Pain stimulation device 10 comprises that micro-injection pump 100, objective physical signs are obtained terminal 200, pain is assessed terminal 300, feedback unit 400 and controller 500.
Objective physical signs is obtained terminal 200 and is obtained tested object 600 and the closely-related physical signs of pain (brain wave, skin conductivity rate, heart rate, respiratory frequency and amplitude, blood pressure etc.) in real time.In conjunction with Fig. 2 is that objective physical signs is obtained the terminal structure sketch map, in the optimum embodiment of this utility model, it is brain wave, skin conductivity rate and the heart rate of tested object 600 that objective physical signs is obtained the physical signs that terminal 200 obtains, and it comprises that the multichannel brain electric wave obtains terminal 210 (preferably using 128 passages), the skin conductivity rate obtains terminal 220 and heart rate obtains terminal 230.
The terminal 210 of obtaining the multichannel brain electric wave adopts two external electrodes to obtain the brain wave of tested object 600, is respectively a brain wave monitoring electrode and a reference electrode.When obtaining brain wave, brain wave monitoring electrode is connected to the motor area of cerebral cortex (CZ) of tested object 600, and reference electrode is connected to the ear of tested object 600.
The skin conductivity rate is obtained terminal 220 and is adopted silver-colored solid reference electrode or silver chloride solid reference electrode to obtain the skin conductivity rate of tested object 600.When obtaining the skin conductivity rate, if tested object 600 is a human body, silver solid reference electrode or silver chloride solid reference electrode be positioned over the finger veutro of human body forefinger, if tested object 600 is animal, silver solid reference electrode or silver chloride solid reference electrode are positioned over the palmar of animal, and sample rate is 200sample/sec.
Heart rate obtains terminal 230 and adopts the heart rate measurement electrode to obtain the heart rate of tested object.When obtaining heart rate, if tested object 600 be human body, the heart rate measurement electrode is positioned over the finger veutro of human body middle finger, if tested object 600 is an animal, the heart rate measurement electrode is positioned over the palmar of animal, sample rate is 200sample/sec.
The multichannel E.E.G obtains terminal 210, skin conductivity rate and obtains terminal 220 and heart rate and obtain terminal 230 and all adopt the electrode contact to obtain the physical signs of tested object 600, tested object 600 is not caused wound, avoid tested object 600 is caused new injury and pain, influence is to the assessment of pain.
Tested object 600 (healthy humans and animals) is except that individual variation, and brain wave all respectively has its characteristics, but with regard to normal adult and animal brain electric wave, its waveform, wave amplitude, frequency and position equate all to have certain characteristics.Height according to its frequency is divided into following four kinds with waveform clinically:
The β ripple: frequency is more than 13C/S, and wave amplitude is about half of δ ripple, and forehead and central area are the most obvious.
The α ripple: frequency is 8 to 13C/S, wave amplitude 25 to 75 μ V, and the most obvious with the top occipitalia, bilateral is roughly synchronous, repeats rhythm and pace of moving things ground and the δ ripple occurs and be called theta rhythm.
The Φ ripple: frequency is 4 to 7C/S, wave amplitude 20 to 40 μ V, and lateral symmetry, see more in the temporo district.
The δ ripple: frequency is below the 4C/S, and delta rhythm is mainly in the frontal region, and one and non-circumscribed δ ripple less than 20 μ V is normal, and focal δ ripple then is unusual.δ ripple and β ripple are referred to as slow wave.
The relation of pain assessment terminal 300 comprehensive a plurality of physical signs and pain to the assessment that pain degree carries out, provides a comprehensive pain assessed value, and the degree of pain is carried out comprehensive reflection.
