Description
[technical field]
This utility model is about medical instruments field, particularly about the tester of the pin pressure pain that can measure tested patient's pain intensity.
[background technology]
Pain is the subjective feeling of clinical patients, is difficult to objectively with its quantification.At present clinical assessment pain is still with some scales and carries out according to patient main suit, like PASCAL evaluation PASCAL scale (VRS) etc.VRS is the subjective feeling according to the patient, with patient experiences to pain come quantization means with " painless (0 minute) ", " slight pain (1 minute) ", " moderate pain (2 minutes) ", " severe pain (3 minutes) " and " extremely severe pain (4 minutes) ".
To the patient satisfied analgesia being provided is the vital task that the medical personnel faces, as: need impose clinical anesthesia before the corrective surgery.Usually, the anesthesia doctor will go out the dosage of anesthetics according to parameter estimations such as the height of Different Individual, body weight, ages.But different individual patients are to a kind of anaesthetic ubiquity sensitivity and toleration difference in various degree.Moreover also there is certain relation in the regulation and control of depth of anesthesia with anesthesia and concrete operations position.So the finely regulating of clinical anesthetic effect is difficulty rather.
In order to obtain depth of anesthesia and range accurately, we must in time understand the reliable feedback information that comes from the patient.Popular way is generally following: after intravertebral anesthesia or the nerve block anesthesia; The hand-held passivity syringe needle of clinician is pressed on the skin that the patient anaesthetizes target site with certain strength; And encourage the probe twinge intensity of the relevant position that patient's readme experiences, carry out the VRS scoring simultaneously.If the VRS that obtains scoring decreases, represent that then anaesthetic effect begins to occur before anesthesia.Certainly, also can this other pain sensation impression of not implementing to anaesthetize the position of pain sensation impression and health of anaesthetizing target site be compared.
But, even holding pin, same position doctor pushes patient skin, the strength of force that he gave also is difficult to guarantee all identical at every turn.
So we can suppose such a case: doctor's handheld probe, the tip is put on patient's non-narcotic position with 100 newton's power, the patient can feel the pain (VRS is 2 minutes) of moderate.
Then, probe tip is applied to patient's anesthesia target site with 100 newton's power, VRS maybe be for 0 minute (anaesthetic effect be fine), also possibly be 1 minute (anaesthetic effect is general) or even 2 minutes (anaesthetic effect is very poor).
But, supposing anaesthetic effect and insufficient at that time, the doctor has but applied smaller strength (40 newton) on probe.Cause the very poor anaesthetic effect of script but to draw the good illusion of anaesthetic effect, influenced accurate judgement clinically.
Therefore, clearly this comparatively coarse appraisal procedure is impossible obtain precisely and the reliable clinical feedback information.
If there is a kind of instrument can show accurately that the doctor puts on the strength on the patient skin through probe, just can assess the effect of anesthesia retardance more accurately, more objectively.
This patent designs to above-mentioned situation.

[specific embodiment]
Alleged here " embodiment " or " embodiment " are meant special characteristic, structure or the characteristic that can be contained at least one implementation of this utility model.Different in this manual local " in one embodiment " that occur not are all to refer to same embodiment, neither be independent or optionally mutually exclusive with other embodiment embodiment.
See also shown in Figure 1ly, it shows the surface structure sketch map of the pin pressure pain tester of this utility model.As shown in Figure 1; In an embodiment of this utility model; The pin pressure pain tester 100 whole outward appearances of this utility model are the shape of similar pen; Be convenient to like this grip, it comprises shell 11, the display screen 241 that is positioned at pin pressure pain tester top that rigid plastics processes, protrudes in three buttons 252 of cabinet and the probe 21 that is positioned at pin pressure pain tester front end.
See also shown in Figure 2ly, it shows the internal structure sketch map of this utility model pin pressure pain tester 100.As shown in Figure 2, this utility model pin pressure pain tester 100 inside comprise probe 21, pressure transducer 22, control module 23, display module 24 and button panel 25.
