A kind of ultrasonic therapeutic apparatus and method of locating pain point
Technical field
The present invention relates to ultrasonic therapeutic technical field, relate in particular to a kind of ultrasonic therapeutic apparatus and method of locating pain point.
Background technology
Myofasical pain syndrome is a kind of with chronic soft tissue source property pain, and the common clinical disease that is principal character with one or more pain points, long-term abnormal sitting posture, the anchor of patient Chang Yin crossed of a specified duration and lasting psychentonia and caused the state of an illness to occur, and common Symptoms is neck shoulder back pain, soft tissue pain, periarticular pain.Through clinical research, show, for pain point treatment myofasical pain syndrome, fundamentally, there is significant curative effect at the sick place for the treatment of to alleviation soft tissue pain and treatment radiculopathy kitchen range.At present, ultrasound wave can be repaired soft tissue affected part owing to having a series of biochemical effects, has become rehabilitation new therapy and has been applied to medical field.But existing ultrasonic therapy equipment universal functionality is single, do not possess pain point and survey checking functions, thereby can not meet multiple Treatment need, affected therapeutic effect.
Pain is a kind of offending emotional experience, body on pain feel affected by society and psychological factor etc., so the reaction of the pain sensation is also had to larger difference.Someone pain threshold is low, has people higher.Meanwhile, treatment doctor has different understanding to patient's language, behavior and manner, and subjectivity is strong, thus in therapeutic process accurate position patient pain point.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of ultrasonic therapeutic apparatus and method of locating pain point.
Object of the present invention realizes by following technical scheme:
A ultrasonic therapeutic apparatus of locating pain point, comprising: control unit, driving matching unit, ultrasonic therapeutic head, parameter acquisition unit and parameter processing unit; Described
Control unit, exports different treatment waveforms according to the treatment parameter of input;
Drive matching unit, according to corresponding treatment waveform, the pulse signal of output certain frequency, amplitude drives ultrasonic therapeutic head work;
Ultrasonic therapeutic head, is provided with transducer, and the high frequency electrical signal after this transducer is processed described driving matching unit converts ultrasound wave to;
Parameter acquisition unit, for the physiological parameter of Real-time Obtaining human body pain;
Parameter processing unit, for pain point testing result is analyzed and provided to the physiological parameter of human body pain, and feeds back testing result in control unit;
And
Control unit sends corresponding indication according to the feedback result of parameter processing unit to ultrasonic therapeutic head.
Locate a method for pain point, the method is based on finger tip blood volume pulsation wave, and described method comprises:
Gather finger tip blood volume pulsation wave signal;
According to the finger tip blood volume pulsation wave calculated signals pulse peak value collecting, decent time attenuation constant and sphygmic interval feature, and by described feature composition characteristic vector;
By support vector machine, characteristic vector is classified, the result of classification is carried out to labelling processing as pain point testing result.
Compared with prior art, one or more embodiment of the present invention can have the following advantages by tool:
When adopting ultrasonic moving treatment method, obtain patient's finger tip blood volume pulsation wave, by analyzing the signal characteristic of finger tip blood volume pulsation wave in therapeutic process, detect pain point, pain point detects result feedback to control unit, it is bright or extinguish the infrared display lamp that is arranged on ultrasonic therapeutic head that control unit detects result points according to pain point, pain point location process is simple, quick, accurate, met the treatment requirement for soft tissue pain's point, improve ultrasonic physiotheraping effect, there is higher clinical application.
Accompanying drawing explanation
Fig. 1 is the system architecture diagram that can locate the ultrasonic therapeutic apparatus of pain point.
The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
Fig. 1 is the system structure that can locate the ultrasonic therapeutic apparatus of pain point, comprises control unit, drives matching unit, ultrasonic therapeutic head, parameter acquisition unit and parameter processing unit; Described control unit, exports different treatment waveforms according to the treatment parameter of input; Drive matching unit, according to corresponding treatment waveform, the pulse signal of output certain frequency, amplitude drives ultrasonic therapeutic head work; Ultrasonic therapeutic head, is provided with transducer, and the high frequency electrical signal after this transducer is processed described driving matching unit converts ultrasound wave to; Parameter acquisition unit, for the physiological parameter of Real-time Obtaining human body pain; Parameter processing unit, for pain point testing result is analyzed and provided to the physiological parameter of human body pain, and feeds back testing result in control unit; And control unit sends corresponding indication according to the feedback result of parameter processing unit to ultrasonic therapeutic head.
Above-mentioned parameter collecting unit comprises finger tip blood volume pulsation sensor and the USB interface being connected with described control unit, and finger tip blood volume pulsation sensor detects slightly blood vessel blood volume-variation of patient's right hand forefinger end, and it is 200Hz that sample rate is set, USB power supply.
Parameter processing unit is according to the finger tip blood volume pulsation wave signal obtaining, calculate the features such as pulse peak value, decent time attenuation constant and sphygmic interval in each cycle, composition characteristic vector, use support vector machine to classify to characteristic vector, the result of classification detects result feedback to control unit as pain point.
Ultrasonic therapeutic head is provided with infrared display lamp, and is connected with control unit with wire or wireless mode, and control unit is lighted or extinguishes according to pain point testing result.
The process of above-mentioned ultrasonic therapeutic apparatus location pain point is as follows:
Gather finger tip blood volume pulsation wave signal;
Patient accepts ultrasonic therapeutic with sitting posture or the mode of lying low, and treatment doctor adopts ultrasonic moving treatment method to find pain point, Real-time Collection patient right hand forefinger end blood volume pulsation wave signal.
According to the finger tip blood volume pulsation wave calculated signals pulse peak value collecting, decent time attenuation constant and sphygmic interval feature, and by described feature composition characteristic vector;
By support vector machine, characteristic vector is classified, the result of classification is carried out to labelling processing as pain point testing result.
It is that pain point is detected to result feedback to control unit that labelling is processed, control unit is lighted by wire or wireless mode or is extinguished the infrared display lamp being arranged in ultrasonic therapeutic head, and treatment doctor can determine patient's pain point position according to the situation of infrared display lamp.Pain point location process is simple, quick, accurate, has met the treatment requirement for soft tissue pain's point, has improved ultrasonic physiotheraping effect, has higher clinical application.
Although the disclosed embodiment of the present invention as above, the embodiment that described content just adopts for the ease of understanding the present invention, not in order to limit the present invention.Technical staff in any the technical field of the invention; do not departing under the prerequisite of the disclosed spirit and scope of the present invention; can do any modification and variation what implement in form and in details; but scope of patent protection of the present invention, still must be as the criterion with the scope that appending claims was defined.
