Description
Technical field
This utility model relates to dry ice therapeutic equipment technical field, and especially one treats rifle.
Background technology
Postoperative pain is that body is stimulated a kind of reaction after (tissue injury) by surgical damage, including the series reaction in physiology, psychology and behavior.In clinical nursing activity, pain has become the 5th vital sign after temperature pulse respiration, the big vital sign of blood pressure 4, is increasingly subject to pay attention to.The body pathology physiological change that postoperative pain causes is not allowed to despise, it not only make circulation, breathe, digest, endocrine, immunity, the system such as blood coagulation change, and violent pain can cause psychic trauma, anxiety, fear, insomnia can be brought, produce helplessness.The nursing intervention of pain mainly has medicine pain relieving (morphine, Pethidine), analgesia pump pain relieving at present.Both the above mode, uses continuously and is certain to affect the recovery of postoperative gastric intestinal peristalsis promoting and urinary function, and rely on medicine for a long time, and side effect is big.
Chronic pain, what currently used comparison was many is neural cryotherapy, is to utilize cryoprobe to produce extremely low temperature (-80 DEG C～-100 DEG C), and low-temperature biological effect makes the teleneuron myelin sheath degeneration of corresponding site lose conduction function and reach pain relieving purpose.Advantage: producing recoverability pathological changes, neuritis seldom occurs, cost of equipment is few compared with radio frequency neurolysis.Shortcoming: produce temporary transient nerve block, need to repeat Cold water stress；Cold probe is relatively big, and the process of percutaneous can be uncomfortable；The success of retardance depends on ice hockey to a great extent and presses close to degree with neural.
Damage induced by radiofrequency hyperthermia method can also treat chronic pain, RF coagulation therapy is to utilize controllable temperature to act on the position such as neuroganglion, dry, root, utilize the diversity that temperature tolerate by different nerve fiber, optionally block conduct the A δ of the pain sensation, fiber C and reach both alleviating pains and retain the purpose of topognosis.Compared with chemical nerve damage therapy, it has a characteristic that the big I 1. damaging stove is accurately controlled；2. damaging temperature can accurately be monitored；3. puncture needle can accurately be placed by means of electricity irritation test and impedance monitoring；4. great majority operation can complete under mild sedation or local anaesthesia.5. most heat setting damages can recover rapidly, and residual symptoms is less；6., under correct operation, complication and incidence of side effects are low；7. recur such as pain symptom, may be repeated Radiofrequency treatment.Shortcoming: apparatus expensive；Operator through training and need to possess certain working experience.
After spraining or dampening, owing to thin vessels ruptures, blood penetrates into surrounding tissue and swelling occurs, and swelling compressing teleneuron also brings pain.And cold compress makes vasoconstriction to block this pathological process.After cold compress stops, when blood recovers normal, undamaged portion body has been carried out repairing and producing blood coagulation, thus alleviates local pastiness and swelling.The longest method is to utilize ice cube to carry out cold compress, and treatment cycle is long, and recovery effects is slow.
Cold therapy pain, is to rise at home the seventies, and in 20 century 70 later stage to the eighties, the many hospitals in the whole nation form focus.But since nineteen ninety, cryotherapy is gradually absorbed in low ebb, its reason is that other new techniques in clinical rise and are extensively applied in recent years, gradually replaces cold therapy such as laser, microwave, radio frequency, gamma knife etc..Current domestic cold air therapy is developed by tradition ice compress therapy and forms, and lowers the temperature the part of health, makes vasoconstriction, regional flow slow down and reduce vigor and the metabolism of cell, thus diminishing inflammation.This mode cycle is long, and cold treat treatment after local organization it is possible that pain.And common cold treatment is cooled to (at most) 12 DEG C at least needs 20 minutes, recovery time is up to 60 minutes, owing to being in hypothermia for a long time, it may appear that destroy the probability of cell.
Study based on medicinal, only reach the remedy measures that the cold treatment side of less than-69 DEG C can become independent.The cold air of less than-69 DEG C has " temperature shock " effect, promotes human body to produce neural feedback excitation, the contraction-degree of depth stretching reaction of induction deep-level blood vessel, thus gets rid of inflammation rapidly.And domestic current carbon freezing therapy is confined to common sublimation process refrigeration or utilizes evaporation process refrigerating method, may only reach between minimum-42 DEG C to-32 DEG C, it is impossible to reach less than-69 DEG C.
Abroad, utilizing high-pressure carbon dioxide to complete a kind of analgesia therapy method that cold therapy is innovation, this theory causes the concern of dealer in being expert at.Relative to the cold treatment technology that other are traditional, this treatment caused quick, can be conducted to nervus centralis by skin receptor and spinal cord bundle close to the skin cooling realized at once, induce human body stress.Specifically, it is simply that the vasodilation of nervus centralis regulation shooting depth after vasoconstriction first.This vasodilation can remove inflammatory mediator, such as serotonin, prostaglandin, histamine, the basic element of cell division etc..The inflammatory mediator quantity causing edema and hematoma so can be made quickly to reduce.Meanwhile, the Vascular permeability imbalance that inflammation causes can recover rapidly normal, so that inflammatory mediator is gradually resorbed and is removed by Venous system within a few minutes.Therefrom it will be seen that this cold therapy pattern is not a kind of symptomatiatria merely carried out by cooling, but a kind of neural reflex pain therapy method, it is a kind of to be directed to source of disease, the treatment means in alleviating pain source.This technology obtains in physiotherapist, rheumatism scholar and athlete soon and supports at present.But, the scientific and effective data about this technology compare shortage at present.
Treatment rifle alignment skin injection CO2Carry out the treatment of pain, such as postoperative wound etc., or injured after the situation of hematoma, edema occurs, find in the research of gastroenterology, generally after the intestines and stomach region finds helicobacter pylori, this infection site can be irradiated 4 minutes by the ultra-blue-light that wavelength is 400-450 nanometer.After these 2-3 days, the stage checked with gastrointestinal endoscope follow-up after belonging to, doctor can confirm that the helicobacter pylori of 90% is killed, owing to anaerobic bacteria is one important component part of wound, wavelength is the blue light auxiliary treatment of 450 nanometers, its wavelength still falls within the scope of blue light, but will not cause visual deterioration when using, and this therapy is with abundant oxygen and the antibacterial environment for the treatment of wound.
