Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the peritoneal dialysis catheter that especially relates to a kind of introduction by magnetic field is located, is resetted, pipe device.
Background technology
Chronic renal failure is the carrying out property progress of various chronic renal diseases, cause the forfeiture of nephron and renal function irreversibility ground, cause take metabolite retention, Water-Electrolyte and acid base imbalance and endocrine disturbance as distinctive clinical syndrome, be uremia the late period of chronic renal failure.
Development along with society, population aging occurs, chronic kidney disease and the chronic renal failure that causes thereof were at the incidence increasing year by year in the whole world in recent years, approximately there are end stage renal failure 2,200,000～2,700,000 people in the whole world every year, and the patient who accepts dialysis treatment is just with annual 10%～12% speed increment.In recent years, gerontal patient especially, the quantity that the kidney damage that diabetes, hypertension, primary small vessel vasculitis etc. cause causes chronic renal failure obviously increases.Annual morbidity in the U.S. and Europe nephropathy in whole latter stage is respectively 336/ million people and 135/ million people.China's chronic kidney disease prevalence is very high, account for 10% of total crowd's sickness rate, the existing uremic patient sum of China has surpassed 2,000,000 people according to estimates, having nearly 1,000,000 patients to depend on dialysis sustains life, and annual new discovery uremia case account for 1,000,000 of China's total population/, uremia is one of common disease that jeopardizes human health.
The primary treatment means in chronic renal failure whole latter stage have peritoneal dialysis, hemodialysis and three kinds of therapeutic modalities of renal transplantation.Peritoneal dialysis is a kind of basically near the dialysis of physiological status, do not affect patient's living habit and social communication, simple to operate, be easy to carry out, can carry out at home, be particularly suitable for the gerontal patient, especially be associated with cardiovascular disease or child or have in the recent period hemorrhage, unstable blood pressure is fixed, live the patient of inconvenient promoting the circulation of blood liquid dialysis from far-off regions.A kind of effective treatment means is not only in peritoneal dialysis, it also is a kind of Therapeutic Method of economy, according to U.S. kidney data base (USRDS) report, each hemodialysis patients year in 2006 cost is 71889 dollars, and the year cost of each patients undergoing peritoneal dialysis is 53327 dollars.Situation is similar in China, according to the insurance payments mechanism research report demonstration to dialysis treatment in 10 Grade III Class A hospitals in national six big cities in 2005 of Insurance meeting medical care insurance branch of Chinese society, hemodialysis year spends 100,000 yuan, and peritoneal dialysis is 78782 yuan.Therefore, under the prerequisite that guarantees the medical science curative effect, consider from the economic angle aspect, peritoneal dialysis treatment also is a kind of therapeutic modality commonly used.
For the patient who relies on peritoneal dialysis to sustain life, peritoneal dialysis catheter is exactly the life pipe of he (she), and keeping the pipe drain unobstructed is prerequisite.Yet one of modal complication is the peritoneal dialysis catheter inadequate drainage in the peritoneal dialysis process, then can not continue dialysis treatment, need again put pipe.Cause that the common reason of peritoneal dialysis catheter inadequate drainage has: omentum majus, mesentery or fimbriae of uterine tube embed from the side opening of peritoneal dialysis catheter abdominal cavity section or main aperture and cause that tube chamber stops up or various inflammatory exudate, albumen grumeleuse and blood clot cause that tube chamber stops up and the peritoneal dialysis catheter drift, and the tissue that needs like this excision to be embedded in peritoneal dialysis catheter side opening or the main aperture makes unobstructed maybe need the operation of tube chamber that the peritoneal dialysis catheter of drift is resetted again.Whenever doing once operation will increase the chance of abdominal adhesions and abdominal cavity infection, repeated infection finally will cause can not continue peritoneal dialysis treatment, if this patient can not carry out hemodialysis or renal transplantation because of a variety of causes, that patient's life just can't be kept, cause very large misery to patient and family, increase the weight of financial burden, increase simultaneously medical personnel's labour force, and greatly waste medical resource, cause burden to society.
Application number is that the Chinese patent of 201210058159.X discloses a kind of " peritoneal dialysis catheter location and adjusting device ", it is to be embedded with paramagnetic metal or the paramagnetism alloy that can accept external magnetic field force effect by the pipeline section at the peritoneal dialysis catheter end, the packaged type magnetic field force that it is outer with being placed in human abdominal cavity and actuator carry out the action of a magnetic field and realize adjusting location to peritoneal dialysis catheter, and specifically disclose paramagnetic metal or the paramagnetism alloy is ferrum, cobalt, nickel.There is following shortcoming in this location adjusting device:
The first, insert in the human body for a long time owing to peritoneal dialysis catheter, and paramagnetic metal or paramagnetism alloy are to be embedded on the pipeline section of peritoneal dialysis catheter end, therefore might have a huge impact human body.Should not in the bedroom, place television set etc. such as present research proposal, exactly because the radiation of television set and the health that magnetic field can affect human body, and will place for a long time in the human body with the object of magnetic field or metal, but also flushing and the long period of soaking that must repeatedly pass through the saturating liquid of peritoneum are containing glucose and electrolyte (sodium chloride, calcium chloride, magnesium chloride, sodium lactate) pH value is in 4.5～6.5 the acid peritoneal dialysis solution, whether these metallic elements can take off mistake, whether people's health caused damage, there are not at present enough evidences can prove not infringement of human body, consider that the skin Long Term Contact can damage human body, therefore long-time safety of placing the people can not guarantee in the abdominal cavity.And in clinical medicine, if can not prove that it is not allow human body is used that certain material does not injure human body.Moreover ferrum, cobalt, these magnetic metals of nickel generally should not place human body for a long time, and being used for people's cognition damages human body, be embodied in: (1) was found the people of nickel allergy is obviously increased in recent years, the irritated number of women increases to 25% by 9%, and the male of nickel allergy is increased to 10% from 1%.Report is abroad arranged, existingly on the clinical medicine wear nickeliferous spectacle frame and cause dermopathic a large amount of case, coin counting person has the nickel of generation to cause dermopathic case, the women uses the metal holder that contains nickel can cause dermatitis, bracelet, safety pin, lipstick box, souvenir badge, pen, knitting wool pin, door handle, pocket knife, metalware that contact contains nickel all can bring out nickel and cause dermatitis, and watch case also can cause dermatosis.Someone has analyzed 18 dermopathic patients (wherein male's 8 examples, women's 10 examples), and reaching a conclusion is to bring out dermatitis and occupational dermatitis, but also can bring out the occupational dermatitis of having cured.Have research to find that 6% people has uncomfortable reaction to metal pontic, nickel has caused the attention of American-European medical circle to sensitivity response and carcinogenic impact that the people produces, and various countries are more and more stricter to the restriction of daily and medical nickeliferous metal material.(2) cobalt can cause the pharyngeal mucous membrane irritation, gastrointestinal irritation then occurs, and vomiting and angina abdominis can be arranged, fervescence, and shank is unable etc., and non-professional contact causes erythrocytosis, cardiomyopathy and thyromegaly, can cause dermatitis.The purity of cobalt is higher, and its harm to human body also may be larger.(3) the medical Magnet of commonly using at present is the highest ndfeb magnet of unit magnetic, suitable the indoor of aeration-drying that exist of this Magnet, the environment that is long placed in acidity, alkalescence, organic solution, water medium and high temperature humidity easily makes magnet produce corrosion, the coating magnet efflorescence demagnetization that comes off.
The second, on the impact of patient diagnosis: the patient of chronic renal insufficiency, the sickness rate of cardiovascular system diseases is very high, although being arranged, various kidney replacement therapies can keep patient's life, but have greatly the patient also not develop into to need dialysis treatment or accepting the kidney replacement therapy dead because of a variety of causes, the modal cause of disease is due to the cardiovascular event.In recent years, increasing evidence showed: angiosteosis and ESRD(nephropathy in whole latter stage) patient's cardiovascular disease incidence rate is high, mortality rate is high relevant.What William G etc. carried out in recent years once confirms from the detection of the aspect research CKD3-4 phase patients' such as vascular endothelium dysfunction, arterial stiffness and angiosteosis abnormal vascular structure, function and angiosteosis on a large scale, and angiosteosis (VC) is that generally (account for total number of persons 74%) is present in the object of study.The incidence rate of CKD patient's heart valvular calcification in dialysis patient approximately is 4-5 times of population, and approximately there is valvular calcification in 45% patient.Because it is very high that the patient of the serious hindrance of renal function merges the chance of cardiovascular disease and cerebrovascular disease, when in case further checking above-mentioned relevant disease appears or is associated with other system disease needs in these patients, because contrast agent should not be used, carry out next step diagnosis and treatment, nuclear magnetic resonance check is very important to these patients, but metal is arranged in the body or contain the object in magnetic field, in case the nuclear-magnetism reaction occurs, nuclear magnetic resonance, NMR can not carry out, cause very large difficulty will for these patients' further diagnosis and treatment, even can cause very serious consequence.In case Consciousness Problem occurs such as the patient, suspection is brain stem lesions, is hemorrhage or ischemic lesions, must determine diagnosis, because treatment is fully different, usually due to illness becoming may be less, and CT examination can not be determined pathological changes sometimes.
Three, on the impact of patient treatment: if support or cardiac pacemaker are arranged in the patient body, this magnet will impact it, is with the magnetic object can be larger on its impact if place in vivo for a long time, and band magnetic peritoneal dialysis catheter in termination just can not be used.Place in the patient body in addition and be with magnetic peritoneal dialysis catheter, in case occur just can not carry out when myocardial infarction, serious arrhythmia, blood vessel Serious Stenosis etc. need placing rack or pacemaker, with regard to entail dangers to patient life, maybe must extract peritoneal dialysis catheter.
