Abstract
The utility model discloses an outer oxygenator of a venous dialysis pot body, comprising a venous pot, wherein the venous pot is internally provided with a hollow fiber type membrane oxygenator; the lower part of the venous pot is provided with a blood inflowing pipe, and the upper part of the venous pot is provided with a blood outflowing pipe; the left upper side of the venous pot is provided with an oxygen inlet pipe, and the right lower side of the venous pot is provided with an oxygen and carbon-dioxide discharging pipe; and the upper end of the venous pot is provided with a venous pressure monitoring pipe and a dosing pipe. The outer oxygenator disclosed by the utility model has the advantages of simple structure, convenient operation, low cost, low treatment risk and the like; oxygenation is performed in dialysis or filtering at the same time, the efficiency is improved, the risk is reduced, the state of a patient is improved, and not only can the generation of serious complication caused by hyoxemia of the dialysis patient be reduced, but also the success ratio of treatment of multi-organ failure is improved; and wide clinical application and popularization can be obtained, and large clinical effect and economic benefit can be generated.
Description
Technical field
This utility model relates to the blood purification technical field of medical instruments, the external oxygenator of especially a kind of dialysis venous chambers.
Background technology
Uremia is the eventually end stage of chronic kidney disease development, chronic kidney disease is present worldwide commonly encountered diseases, approximately in world population sickness rate between 10.0%-12.6%, and present about 12/1000 population of uremic sickness rate theoretically, uremia's prevalence of accumulation approximately is 60/1000 (UNRDS, 2008, ADR).Uremic effective Therapeutic Method is dialysis and transplants, but because donor and costs constraints, present uremic primary treatment method remains dialysis, therefore, nearly 1,000 ten thousand people rely on dialysis to sustain life in the world now, and this quantity every year is just increasing with about 5% rate of increase, and in China, nearest three annual annual rate of growth have surpassed 20%.
Many dirty declining are one of emphasis of clinical medical attention over nearly 20 years, and sickness rate is high, mortality rate is high, medical resource consumption is also high.Only owing to infect how dirty the declining of causing 750,000 people are just arranged in U.S. every year, have similar every day 2000 examples to occur, annual because infect the medical expense more than $ 10 billion of the how dirty cost that declines that causes, and be every year and increase progressively state.This does not also comprise because how dirty the declining that wound or major operation cause.Many dirty important pathophysiological difficult problems that decline are exactly hypoxemia, therefore process and the hypoxemia when improving how dirty declining is one of how dirty key measure of giving treatment to of declining.
In the dialysis, especially dialysis just begins, because dialyzer contacts with blood, the series reaction such as primosome endocomplement system, Kallidin I system, blood coagulation system, histamine system, especially the poor dialyzer of biocompatibility, as ketone ammonia film, the improvement the caused reactions such as cellulose membrane more not remarkable, the reaction of multisystem, too many levels, an important feature is that hypoxemia appears in patient in body.Begin beginning in about about 15 minutes in dialysis, Blood of Patients oxygen saturation, partial pressure of oxygen etc. all obviously descend.Hypoxemia the lighter can cause the performances such as blood pressure drops, drowsiness, weak, nausea and vomiting, and severe one can cause patient to go into a coma and the complication such as heart and brain severe ischemic death.
In how dirty declining, a plurality of systems of a plurality of organs of patient can cause the hypoxemia except dialysing or filtering through overwhelming, and disease itself also often causes serious hypoxemia, and hypotension, shock, stupor even death appear in patient.Many dirty row dialysis or filter the risk that increases the weight of hypoxemia is arranged of declining, and extremely need blood purification treatment during how dirty declining.Therefore if in dialysis or improve the oxygen content of blood in filtering, improve partial pressure of oxygen and blood oxygen saturation, all very meaningful to Complication of dialysis and the how dirty treatment that declines.
The utility model content
The purpose of this utility model is to provide a kind of external oxygenator of dialysis venous chambers that is used for the treatment of uremic patient and the how dirty patient of declining in order to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: the external oxygenator of dialysis venous chambers, comprise venous chambers, the inside of described venous chambers is provided with the membrane oxygenator of hollow fiber type, and described venous chambers bottom is provided with the blood inflow pipe, and top is provided with the blood effuser.
The upper left side of described venous chambers is provided with oxygen and enters pipe, and the lower right side is provided with oxygen, carbon dioxide discharge pipe.
The upper end of described venous chambers is provided with venous pressure monitoring pipe and chemical feed pipe.
The beneficial effect that this utility model has is:
The utlity model has the advantages such as simple in structure, easy to operate, that expense is cheap, Operative risk is low, while oxygenate in dialysis or filtration, improved efficient, reduced risk, improved patient condition, not only reduce the generation of the severe complication that the dialysis patient hypoxemia causes, also improved the success rate of the how dirty treatment that declines; Widely clinical practice and universal can be obtained, huge clinical effectiveness and economic benefit can be produced.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Do following detailed description below in conjunction with 1 pair of this utility model of accompanying drawing.
As shown in Figure 1, this utility model comprises venous chambers 1, and the inside of described venous chambers 1 is provided with the membrane oxygenator 2 of hollow fiber type, and described venous chambers 1 bottom is provided with blood inflow pipe 3, and top is provided with blood effuser 4; The upper left side of described venous chambers 1 is provided with oxygen and enters pipe 5, and the lower right side is provided with oxygen, carbon dioxide discharge pipe 6; The upper end of described venous chambers 1 is provided with venous pressure monitoring pipe 7 and chemical feed pipe 8.This utility model makes in the dialysis procedure, blood has improved partial pressure of oxygen and blood oxygen saturation directly, effectively in the loop, reached the purpose that overcomes these difficult problems with simple method, make dialysis and how dirty declining that a kind of safe, easy, direct, effective, inexpensive method and apparatus that combines blood purification and external oxygen and two treatment measures arranged, can in dialysis, improve partial pressure of oxygen and the blood oxygen saturation in the patient blood, improve the state of patient's hypoxemia.
This device uses in dialysing and filtering in the lump, owing to improved patient's hypoxemia state, can greatly improve the patient of uremia the toleration of dialysis is given treatment to success rate with the how dirty patient of declining.Especially decline when patients underwent CRRT or CBP how dirty, sustainable, directly, effectively improve patient's partial pressure of oxygen and blood oxygen saturation, greatly improved the how dirty patient's of declining state, to the life of saving patient play key, actively, effectively effect.
