Description

Stem bronchi cell precise positioning slow-released system
Technical field
It is slow more particularly to stem bronchi cell precise positioning the present invention relates to treatment acute respiratory distress syndrome method Release system.
Background technique
Acute respiratory distress syndrome (ARDS) is as caused by intrapulmonary reason and/or extrapulmonary reason, with intractable hypoxemia Mass formed by blood stasis is the clinical syndrome of notable feature, is received much attention because of high case fatality rate.The cause of disease of acute respiratory distress syndrome is various, Different pathogeny induced Acute Respiratory Distress Syndrome(RDS) pathogenesis is also had nothing in common with each other.Clinical manifestation be in more Acute onset, breathing it is embarrassed Compel and be difficult to the hypoxemia etc. corrected with conventional oxygen therapy;Currently, " Berlin definition " is mostly used to pay a home visit ARDS in the world The layering of disconnected and severity, and antidiastole need to be carried out with a variety of diseases.Clinical examination content is related to:Diagnosis and differential diaggnosis, Treatment monitoring and guiding treatment, severe degree and prognosis evaluation and test etc.;Treatment of ARDS includes that mechanical ventilation is controlled It treats and still is continuing to explore with on-mechanical ventilation therapy two major classes, effective treatment method.
The cause of disease of acute respiratory distress syndrome includes intrapulmonary reason and extrapulmonary reason two major classes.Intrapulmonary reason includes:Lung Inflammation, accidentally suction, contusion of lung, drowning and noxious material sucking, lung other factor include:Severe systemic infection, severe multiple injuries (multiple bone Folding, flail chest, serious brain traumatism and burn), shock, high-risk operation (openheart surgery, main artery operation etc.), massive transfusion, medicine Object is poisoned, pancreatitis and cardiopulmonary bypass are postoperative etc..In addition, the cause of disease of ARDS can also be divided into biological cause according to pathogenic former different Cause of disease and abiotic pathogenic former two major classes:It includes mainly multiple pathogens that biology, which causes a disease former, such as bacterium, virus, fungi, atypia Pathogen and partial injury associated molecular pattern (DAMPs), malignant tumour etc.;It is abiotic it is pathogenic it is former mainly include acidic materials, Drug, toxic gas sucking, mechanical ventilation associated injury etc..
Mechanical ventilation is the essential therapeutic arsenals of Patients with ARDS.Not according to mechanical ventilation mode Together, invasive ventilation and Invasive vent ilation can be divided into, invasive ventilation relies on mask and ventilates, and Invasive vent ilation then relies on trachea cannula Or catheter for tracheostomy is ventilated, the two selection need to rely on the specific state of an illness and determine opportunity;Currently, being directed to acute respiratory distress The ventilation tactics of syndrome patient mainly include the following contents:Lung preversation ventilation strategies (small tidal volume ventilation [LTVV], pressure Power limit ventilation, permitted deformation [PHC], inverse ventilation, PEEP application etc.), Open lung Approach (particular technique packet It includes:Lung recruitment [RM], best PEEP application and selection of Mechanical Ventilation Modes etc.) and mechanical ventilation adjuvant treatment (air flue Innerlich anwenden [nitric oxide, prostaglandin], prone-position ventilation, external mould lung oxygen conjunction technology etc.).
Though the on-mechanical ventilation therapy means of acute respiratory distress syndrome are more, its reliable curative effect is not yet determined so far. On-mechanical ventilation therapy means include:Edema with the lung involved is removed and liquid management, alveolar surfactant replacement therapy, statins Using the application of, glucocorticoid, anti-coagulants application, antioxidant and the application of enzyme inhibitor, blood purification treatment, nutritional intervention Deng;But the effect for the treatment of is not ideal, there is deficiencies.
In conclusion in view of the drawbacks of the prior art, it is accordingly required in particular to stem bronchi cell precise positioning slow-released system, with solution Certainly the deficiencies in the prior art.
Summary of the invention
Aiming at the problems existing in the prior art, use in practice is influenced, the present invention proposes that stem bronchi cell is accurate Positioning and slow release system, it is novel in design, using visual operation, stem cell is accurately injected to intrapulmonary, is controlled with reaching optimal Therapeutic effect has solved the defect of the prior art.
To achieve the goals above, technical scheme is as follows:
Stem bronchi cell precise positioning slow-released system, including endoscopic system, endoscopic system are led by flexible Light beam is inserted into lung, and the information of lung is transmitted to the display screen of endoscopic system by the optic probe of light guide bundles bottom, visualizes Display screen provide and accurately operate for operation, light guide bundles are internally provided with the anesthesia sustained release that patient comfort is promoted when operation System, the inside of light guide bundles are additionally provided with stem cell slow-released system, effectively treat acute respiration by precisely discharging stem cell Distress syndrome, stem cell slow-released system are set to the lower section of anesthesia slow-released system, anaesthetize slow-released system, stem cell slow-released system The external triple valve in light guide bundles surface is connected by conduit, the corresponding conduit of triple valve connects corresponding infusion system.
Reticular structure is used in stem cell slow-released system of the present invention, the hole of reticular structure is set as stem cell release Mouthful, the diameter of stem cell liberation port is equal to the diameter of stem cell.
Further, the filter membrane for including of the anesthesia slow-released system, the surface of filter membrane are provided with several sustained release holes, The diameter for being sustained hole uses nanoscale.
Further, the side of the optic probe is provided with positioning device, and positioning device is positioned using B ultrasound or CT is fixed Position.
Further, the treatment method of stem bronchi cell precise positioning slow-released system:First in the light guide bundles of endoscope Inside is respectively connected to anesthesia slow-released system, stem cell delays system, the optic probe side mounting and positioning device of endoscope bottom, fiber crops Liquor-saturated slow-released system, stem cell slow-released system connect the external triple valve in light guide bundles surface by conduit, gate in treatment Triple valve injects anaesthetic to anesthesia slow-released system, and the speed of injection can flexibly be controlled by syringe pump, promotes operation patients Comfort level, since the sustained release hole of anesthesia slow-released system uses nanoscale, so anesthesia can be slowly diffused in vivo, then The light guide bundles of endoscope are inserted in the lung of human body, during insertion, can directly be seen by the optic probe of endoscope To position of the endoscope in people, then reaches between treatment position, stem cell, Er Qiegan are implanted into human body by triple valve Cell also uses slow-released system, and the diameter of stem cell is identical with the diameter of stem cell liberation port, can accurately discharge stem cell, To reach optimal therapeutic effect.
The beneficial effects of the invention are as follows:This product is novel in design, using medical endoscope, enables to observe lung when operation Variation, make stem cell release at effective position, to reach better therapeutic effect, and perform the operation and use local anaesthesia, promoted The comfort level of patient, practical performance is excellent, is a kind of good innovation scheme, is very promising for marketing..
