Description
Technical Field
The invention relates to the field of pain sensation examination, in particular to a puncture-preventing portable pain sensation measuring pen and a using method thereof.
Background
In clinical medicine, to examine the pain of a patient, a test is conventionally performed by using a lancet method, such as that used in chinese patent CN201020641388.0 (a pain tester). In medical clinical work and scientific research, different diseases (particularly nervous system diseases) need to be identified and positioned by accurately measuring the pain sensitivity of the skin of a patient, and the clinical intervention effect needs to be evaluated, but the traditional puncture needle method has the defect that the quantitative measurement cannot be carried out.
In order to overcome the defect that the traditional pricking needle method cannot quantify, the pricking needle is improved by people, the pricking needle is changed into a group of pricking needles from thin to thick, each pricking needle represents different pain sensation sensitivity, the pain sensation of the skin of a patient is checked by adopting the method of elastic deformation of the pricking needle, namely, when the pressure applied to the needle handle reaches the pain sensation measurement area marked by the needle, the pricking needle is bent. When the pain sense measuring instrument is used, an examiner firstly selects the puncture needle with smaller pain sense strength according to clinical experience to examine a patient, if the puncture needle is insensitive, the pain sense strength of the puncture needle is increased in turn until the patient feels pain, and therefore the measurement of the pain sense of the patient is achieved. Although this method achieves a semi-quantitative measure of the patient's pain sensation, the measured value of the pain sensation represents only a rough pain sensitivity threshold (pain pressure value) of the patient, the quantitative scale is still relatively coarse, and there is a risk that the patient's skin may be pricked. In addition, the measuring needle is made of special metal materials, so the price is high, and the measuring needle is difficult to popularize and apply in clinic.
Chinese patent CN201120577601.0 (quantitative pain measuring instrument for tenderness) adopts a pressure sensor to realize quantitative measurement of pain sensation of a patient, but the volume is large and it is inconvenient for medical staff to carry. Chinese patent cn201410682634.x (portable sensory function tester) also uses a pressure sensor to measure pain sense of a patient quantitatively, but for patients with skin insensitivity such as the elderly, the design of the portable sensory function tester still has the risk of skin injury of the patient, and is not convenient for medical staff to carry with them.
