Abstract
A digital pen type pain evaluation device is provided, which includes a shell, a measuring head, circuit and circuit board designed in the shell, a touch force sensor, batteries, and a digital display device. The measuring head referred is connected to the shell firmly through the screw. A needle inset is connected to the internal of the measuring head through the screw. A probe is disposed in the needle inset in a sliding state, the tip of which extends outside the measuring head. The needle end contacts to the manometry spherical surface of the touch force sensor. The tip end of the probe feels the external force and turns the external force into electrical signal through the touch force sensor. Then, the electrical signal is amplified by the circuit and displayed by the digital display device after analog-digital conversation. The utility model can measure the pain of the patient quantitatively, which can completely change the present measure fashion that judging the pain by the feeling and experience of the doctor. The utility model is in favor of carrying out the pain measuring standardization and can provide reliable data for the clinical diagnosis, medical education, and scientific research, which is a revolution to the present clinical pain measuring method. The utility model has a simple structure, a small figure, which is convenient to carry about. The measurement done by the utility model is accurate, and the utilization is very convenient.
Description
Technical field
This utility model relates to medical apparatus and instruments, refers to a kind of survey pain device especially, specifically refers to a kind of digital pen type ache measure needle that adopts touch force sensor and electronic digital technique to combine.
Background technology
In view of international medical community is not verified as yet to the mechanism of pain, present clinical examination to Sensory nerve fibre is all based on sense of touch, the pain sensation and 2 sense of discrimination.Wherein pain sensation inspection is to be instrument with the pin, [referring to " hand surgery " (Wang Shuhuan, Gu Yudong, wait upon moral chief editor, Science and Technology of Shanghai publishing house, 133 pages) and " practical hand surgery " (Tianjin down strong (Japan), Nan Jiangtang publishes, the 352nd page)].During inspection, the doctor is with the direct puncture patient skin of common pin, the pain of inquiring the patient simultaneously, judge and classification by the doctor again, according to character, degree and the scope of dysalgia, judge the degree of nervous system disease again, further check, the foundation of treatment and rehabilitation.But pin is surveyed pain a lot of drawbacks are arranged.At first, when doctor acupuncture treatment exerts oneself to tend to prick skin when excessive, harm people soma, even cause infection; Moreover the firmly weight during doctor's puncture skin is difficult for grasping, and the evaluation of the pain sensation is entirely with doctor's subjective judgment and clinical experience, same symptom, and different doctors can draw different conclusions; Its three, the major part skill of handling needles can not be according to " threshold of pain " of different crowd, makes that valuable " pain value " is shown, and the pain sensation of human body is made objective appraisal.
Summary of the invention
The purpose of this utility model is to propose a kind of digital pen type ache measure needle, make the doctor when the test pain sensation, can in conjunction with the main suit of experimenter, show corresponding numerical value according to its size of exerting oneself to the pain sensation, realize the digitized of the pain sensation, the pain sensation of human body being made objective appraisal.
Digital pen type ache measure needle of the present utility model, mainly by housing, measuring head, be located at the intravital electronic circuit of shell and circuit board, touch force sensor, battery and numeric display unit are formed, described measuring head is connected with housing mutually with screw thread, be provided with a needle guard in the measuring head by being threaded, the sliding probe of establishing in this needle guard, needle tip stretches out in outside the measuring head, and the backshank end contacts with the pressure measurement sphere of touch force sensor; The external force that probe tip is experienced converts the signal of telecommunication to by touch force sensor, and is shown by numeric display unit after electronic circuit amplification, analog digital conversion.
Described probe returns to zero on request with the initial pressure that touch force sensor pressure measurement sphere contacts.
Digital pen type ache measure needle of the present utility model can be designed to lip pencil, is convenient to the doctor and carries.
When measuring patient's pain sensation, the doctor contacts with patient skin with probe 9, and the pressure on the probe converts the signal of telecommunication to by touch force sensor, and shows with digital form, the sensation in conjunction with the patient to the pain sensation, just can realize " pain sensation " quantification.
Contribution of the present utility model is: can carry out quantitative assay to patient's the pain sensation, thoroughly change now by the doctor with sensation with through the mode of test pain, help carrying out pain sensation testing standardization, can be clinical diagnosis and medical educational, scientific research provides reliable data, is the revolution to existing clinical pain sensation method of testing.
Of the present utility model simple in structure, profile is small and exquisite, is easy to carry; Measure accurately, easy to use; Highly sensitive, practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of measuring head of the present utility model;
Fig. 3 is a flow chart of data processing block diagram of the present utility model;
Among the figure: 1 housing, 2 measuring heads, 3 electronic circuits and circuit board, 4 numeric display units, 5 pen clips, 6 batteries, 7 needle guards, 8 touch force sensors, 9 probes, 21 signal amplification circuits, 22 signal holding circuits, 23 signal comparator circuits, 24 coding circuits, 25 decoder driver circuits, 26 display devices.
Embodiment
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing.
As Fig. 1, this utility model is designed to the pen type structure, mainly by housing 1, measuring head 2, be located at the intravital electronic circuit of shell and circuit board 3, touch force sensor 8, battery 6 and numeric display unit 4 are formed.
As Fig. 2, described measuring head 2 is connected with housing 1 mutually with screw thread, is provided with a needle guard 7 by being threaded in the measuring head 2, slides in this needle guard 7 and establishes a probe 9, and needle tip stretches out in outside the measuring head, and the backshank end contacts with the pressure measurement sphere of touch force sensor 8; After external force is experienced at probe 9 tips, move behind the probe 9 and apply pressure to touch force sensor 8, and convert the signal of telecommunication to by touch force sensor 8.
The initial pressure that described probe 9 contacts with touch force sensor 8 pressure measurement spheres can be regulated by the connecting thread on the sliding sleeve 7.
