Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of administration apparatus changing disease treatment convenient administration approach, particularly relates to a kind of Sigmoid colon administration apparatus.
Background technology
Present people's disease therapy, mostly every medicine needing to enter in body, be by mode administration that is oral or that have an intravenous drip.During oral drugs, have abnormal flavour to stimulate, especially infant not easily accepts more, more has gastric acid and digestive enzyme to affect drug effect.
Having an intravenous drip in China is quotidian thing, no matter adult or infant ill, as long as hang up transfusion bottle treatment, patient and family members go up at heart and namely obtain peace wish, otherwise often interrogate doctor.So " transfusion hall " is absolutely necessary in the medical institutions of China.This scenery feels more surprised after making foreigner see, the doctor of foreign country is then mostly to this is again and again shake the head, with sound " NO! " " NO! ".The country that science and technology is advanced, the treatment of infantile diarrhea does not also take venous transfusion, if need supplementary moisture content and electrolyte, is then oral " ORS " liquid.Because it is more harm than good that extension transfusion bottle is had an intravenous drip real.For this reason, to many undesirable elements brief description in addition of venous transfusion.
One, have an intravenous drip and make medicine directly enter blood circulation of human body, cross the effect that the human body natural cover for defense is checked on, this is just easy to cause the unexpected generation such as excitation, metamorphosis and anaphylaxis, tool China China Alliance for Safe Injection statistics, China causes death toll to reach more than 390,000 because of unsafe injection every year, is the major reason causing medical tangle.
Two, have an intravenous drip and make a large amount of particulate matter in medicinal liquid directly enter blood.
Particulate matter is the microgranule of less than 50 microns, invisible, and this microgranule can produce from medicinal liquid itself, also by transfusion utensil, or may produce when medicinal liquid is produced, enters in your blood when you infuse.Some doctor is easy to ignore particulate matter to the potential eutrophication of patient." to have an intravenous drip " blood circulation making medicinal liquid directly enter human body; because the blood capillary diameter of human body is generally 4-7 micron; so frequent or a large amount of medication infusion intravasations; particulate matter will be accumulated in the abundant vitals such as the heart, lung, kidney of blood capillary in large quantities; in the course of time; microvascular thrombosis infraction, lung internal granuloma, pulmonary fibrosis, pulmonary venous pressure, pulmonary artery pressure will be caused to increase; and local organization edema, inflammation, necrosis, even cause gene mutation and produce cancer etc.And also can cause microcirculation dysfunction.
Meanwhile, stifled the amassing of microgranule also can cause local blood supply insufficiency, tissue ischemia, anoxia, edema and inflammation, allergy etc.The a large amount of microgranules entered in human body with infusing, by after macrophage phagocytic, can make macrophage increase, and form granuloma.Because transfusion is also a kind of stimulation to blood vessel, long-term infusion often can cause vein inflammation, occurs that congestion and swelling pain, local body temperature raise, even hardens.Although infusion treatment effect is strong, instant effect, its harm and untoward reaction are also very outstanding, and infusion treatment causes serious harm by the health of patient improperly
Three, have an intravenous drip and affect immune function of human body, easily cause Drug resistance.
Medicine directly enters blood as foreign body, eliminate the abundant lymph cluster of intestinal epithelial tissue to its " safety check ", but the immune bodyguard in blood can carry out strick precaution to emergent foreign body immediately and interfere, light then transient excitation is heavy then occur anaphylactic shock even threat to life.If long-term prescription, then immune bodyguards then can anopia, is accustomed to, ignores, show as immunologic hypofunction.Especially antibiotics, the result of long-term drop is that pathogenic microorganism can suddenly change by producer, and make antibiotic become self available brother and lose its due effect, produce drug resistance, this endangers very large consequence.
Four, the person that often do not have an intravenous drip easily produces dependence syndrome
In clinical position, often have the patient requests's doctor prescribed drop treatment getting used to having an intravenous drip, this people creates the dependence as addiction from psychology and body, i.e. current so-called transfusion dependence syndrome.Be common in the Nonorganic lesion patient that symptom is more, be characterized in taking medicine being difficult to take effect, have an intravenous drip and just can deal with problems.Hypoimmunity and drug resistance will inevitably be produced if things go on like this, if contracted a serious illness later, even curative effect of having an intravenous drip also can not show a candle to the person that seldom do not have an intravenous drip.
Five, have an intravenous drip and easily cause human body Tiny ecosystem functional disorder
Be mainly manifested in self dysbacteriosis and environment imbalance:
For dysbacteriosis.Health be unable to do without the help of normal beneficial bacteria group.Such as, the existence just having numerous probiotic bacteria to help us in our digestive tract to digest and assimilate nutrient substance and suppress to eliminate pathogenic bacterium.Application antibiotic if inappropriate, direct from transfusion bottle input antibiotic especially for a long time, a large amount of beneficial flora of result is suppressed, and pathogenic bacterium may be benefited on the contrary, and this dysbacteriosis is very large to health hazard.
For environment imbalance, human normal water, electrolyte, acid-base value and anion gap are dynamic equilibrium, and this maintains the vital environment of human metabolism's vital movement.Without the conditioning of epithelium of intestinal mucosa tissue when having an intravenous drip, large quantity of fluid directly enters body, and environment is changed, and may affect normal metabolic function, very unfavorable to health.
Six, infant is heavy calamity family
Current Pediatrics Department widely uses has an intravenous drip, especially infantile fever flu, the overwhelming majority is viral infection, but is mostly the expensive antibiotic such as cephalo three generations, Novel macrocyclic lactone or third generation quinolones in transfusion bottle, just not saying invalid to virus, antibiotic side effect is harmful.In addition repeatedly prick scalp acupuncture, or the back of the hand, dorsalis pedis vein puncture hurt like hell, infant fears Fear scaring especially, and crying and screaming restless, is really disaster one.
Therefore, in the face of China is ubiquitous, not too meets the having an intravenous drip of medical science requirement, hang the reality that transfusion bottle overflows, numerous medical personnels appeal to strengthen communication and education, are improved by every means from route of administration aspect simultaneously.
