Description
Technical field
This utility model belongs to medical instruments field and in particular to a kind of quick measurement apparatus of machinery pain.
Background technology
It is known that pain is a kind of complicated experience and experience, including feeling to distinguish, emotion motivation and cognitive appraisal three
Individual key component.It is now recognized that when the pain increased or body is subject to inflammation or various damage to attack, pain no longer plays
Protective effect, gradually develops into chronic pathological pain, not only can cause sensory disturbance (spontaneous pain, hyperpathia
Quick with abnormal pain), also many higher brains can be had influence on by up pathway, such as：Emotion, cognition, memory etc., thus
Lead to many cognitive disorder related to pain and mental sickness, such as：Anxiety, depression, forgetful, insomnia, cognitive impairment etc..Slowly
Property pain be a kind of nervous function disease or functional brain disease, the cause of disease is complicated, and mechanism is unclear, diverse clinical manifestations, controls
Treat difficulty big.According to epidemiology statistics, in world population, chronic pain sickness rate has reached 30～35%, and wherein 27% with insomnia,
49% with disability, and 60% with depression.Chronic pain has severely impacted the Health and Living quality of people.
Comorbidity (comorbidity) is also known as with disease, the combination of syndromes, comorbiditieses.First by Yale Feinstein in 1970
Secondary proposition.The definition of Campell psychiatry dictionary in 1989 is：Comorbidity refers to same patient simultaneously or within the specific time
With 2 kinds or two or more different disease, and every kind of disease has all reached diagnostic criteria, not reciprocal causation between several diseases,
Each own different independent pathophysiological mechanism.With depression in chronic pathological pain, can be described as pain comorbidity.At present,
The comorbidity problem of chronic pathological pain and affective disorder drastically influence sensory function and the quality of life of patient, therapeutic strategy and
Related mechanism research is also very limited, needs to carry out further preclinical and clinical research and exploration.Therefore, pain comorbidity is asked
Topic is the forward position focus of neuroscience field.
Chronic pathological pain is disease that is most common and lacking treatment meanss most, especially neuropathy in clinical chronic pain
Rationality pain even more becomes one of emphasis and difficulties of clinical treatment.Neuropathic pain is by periphery or the horizontal body of maincenter
The damage of body sensory system and disease and the pain that directly contributes.Its pathogenesis is complicated, can involve multiple location nervous system, bag
Include peripheral nerve injury (diabetic nerve damage pain, peripheral nerve injury, postherpetic neuralgia) and nervus centraliss
Damage (post-stroke pain, spinal cord injury, multiple sclerosiss etc.).Epidemiological study shows, exists close between pain and depression
Cut dependency, the pain incidence rate of depressed crowd and pain population's incidence rate are above each single incidence rate, pain and depression
Suffer from rate average out to 50%～60% altogether.Wherein, depressed and anxiety sickness rate in crowd is 16% about, but in chronic pain patient
In have higher sickness rate to be about 35%.Pain and depression usually comorbidity, both frequent juxtapositions, patient's function when coexisting
Infringement is bigger, and quality of life is worse.Therefore, treatment chronic pathological pain is extremely urgent with depressed comorbidity problem.
Chronic pain not only affects attention, has an effect on various memories and is formed.Substantial amounts of research provides and confirms
Pain can cause amnesia.At the same time, some documents also report inflammatory pain and the animal model of neuropathic pain can
Impact cognitive process.Praxiology research finds that SNL and peripheral nervouss pathologic pain model (PSNL) can lead to different degrees of recognizing
Know dysfunction.Chronic pathological pain may result in many mental sickness related to pain and cognitive disorder, such as：Anxiety, suppression
Strongly fragrant, forgetful, insomnia, cognitive impairment etc.；And depression is the main Types of affective disorderses, clinically with notable and lasting
Mental state low for principal character, serious harm human physical and mental health, homicide rate raises year by year in the world in recent years.Mesh
Front all do not have effectively treatment mode to chronic pain and depression, then when both coexist, clinical treatment is even more extremely difficult.
Pain is accompanied by the sense in the sensation a kind of beastly and emotion of existing or potential tissue injury
It is subject to, common pain stimulation form includes hot and cold, chemical (formalin, acetic acid) stimulation, pressure, laser, electricity, Bee Venom etc..
Mechanical nociceptive is one of clinically common pain, refers to that body or histoorgan produce machinery change in the presence of external force
Shape, when the degree of deformation exceedes the threshold value of mechanical nociceptor, the pain that sensor is activated and produces.
With the continuous development of medical level, new surgical technic is more and more applied to clinic, to obtaining
Good curative effect, farthest mitigates the misery of patient simultaneously.But, postoperative pain is still impact patient's postoperative quality of life
Key factor.The research in past shows, for different patients, its postoperative pain degree, persistent period and tolerance level exist
Significantly individual variation, and these differences receive physiology, the impact of the many factors such as psychological and social.Among these, operation in patients
Front pain sensitivity is considered as an important predictor judging postoperative pain state.Pain after operation in patients is controlled
Treat, clinical general by the way of more passive, that is, patient has during demand and gives certain analgesia therapy.Although automatic-control pain-relieving device
(patient control analgesiadevice, PcAD), such as analgesic pump etc. apply for many years in clinic, but for multi-party
The reason face, preoperative decision-making during its use is still subject to many limitations.Therefore, if the pain sensitivity before operation in patients can be entered
Row test, its postoperative pain status of anticipation are it is possible to for the prevention of clinical postoperative pain and Decision-Making Intervention offer side can be formulated
Help.
Need in research work to carry out effective pain test to experiment with rat or patient it is therefore an objective to survey by accurate
Amount counts its pain threshold, to provide unified experiment benchmark for research work.But lack easy in current research work
Easy pain test instrument device, in clinical position, tests, to the pain of patient, the master that can only rely on scale and patient itself at present
See and judge, there is no a kind of objective effective assessment method and device.Therefore design a kind of dress of quick detection mechanical nociceptive
Put, and accurate practical purpose can be reached in use, be preferably research work and clinical treatment service, there is weight
Want meaning.
