Description
Technical field
The present invention relates to a kind of cell culture experiments device, more precisely a kind of cell anoxia experimental facility at intermittence.
Background technology
Sleep apnea syndrome (sleep apnea syndrome, SAS), especially obstructive sleep apnea low syndrome (obstructive sleep apnea-hyponea syndrome, OSAHS), be the chronic sleep-respiratory illness that a kind of sickness rate is higher, have a strong impact on people's physical and mental health.SAS means every night 7h sleep, breathlessness repeatedly show effect more than 30 times or sleep disordered breathing time index (respiratory impair time index, RIT, i.e. average sleep apnea number of times per hour+low ventilation number of times) >=5 times.Cause thus the hypoxemia and the hypercapnia that repeatedly occur, on body, can produce many-sided impact: as drowsiness, dizzy weak, mental act abnormal, play morning such as headache etc.With disease progression, can there is the severe complications such as pulmonary hypertension, pulmonary heart disease, respiratory insufficiency, hypertension, heart disorder.
Although SAS has been carried out to some relevant researchs, its clinical manifestation and substantially clear on the impact of internal organs both at home and abroad.But up to the present,, the pathogenesis of SAS does not still understand, is mainly in default of a kind of animal model comparatively approaching with SAS pathogenic process.So, copying the animal model close with SAS nature pathological and physiological condition, the pathogenesis to research SAS, formulates prevention and treatment measure, all has great importance.Due at present still unclear to this sick cause of disease, pathogenesis, on human body, study certain limitation, so it is particularly important that the research of relevant animal model seems, for this reason, the applicant is by having researched and developed for many years multiple intermittent hypoxia Animal feeding cabin, the name of Bing Yi Wenzhou Medical College has been declared respectively patent of invention: 1. SPF level intermittent hypoxia rat feeding compartment, and the patent No.: 200610052684.5, authorize day: 2008.7.25.; 2. intermittent hypoxia big and small mice feeding cabin of loop track type, the patent No.: 200910099827.1, authorize day: 2011.05.04.; 3. intermittent hypoxia big and small mice feeding cabin of linear track type, the patent No.: 200910099828.6, authorize day: 2010.12.08.; 4. hypoxemia Animal feeding cabin fault emergency protecting equipment, number of patent application: 201210059548.4 applyings date: 2012. 3.8.By the test to the animal model of animal for many years, the pathogenetic research of SAS is also made some progress.Yet because comprise that the mankind's biology is comprised of cell, cell is the fundamental unit of organism structure and function, organism is that the activity by cell reflects its function.Cell is a relatively independent unit, and existing his life works for the common whole life forming of other cells again, and biological generation disease is because its cell malfunction.But to the research of SAS, be to be all based upon on the animal model of intermittent hypoxia conventionally both at home and abroad at present, not yet further carry out the research of intermittent hypoxia cell.Some experimental study is to adopt animal model to do, and some is more reliable with cell experiment, more careful, and also having in addition some cell experiments is supplementing of animal.Due to intermittently anoxic experiment of cell, gas frequently flows and exchange, can take away moisture content and heat in Laboratory Module during gas flow, now keeps the constant very important of the interior humidity of Laboratory Module, temperature, to ensure that cell can normal survival and growth.And existing intermittent hypoxia Animal feeding cabin is owing to not having the environment of constant temperature, constant humidity, existing two gas, three gas cell culture incubators cannot carry out frequent exchange and humidity is controlled, therefore all do not have the research of carrying out intermittent hypoxia cell, be badly in need of intermittently anoxia experimental facility of a kind of cell of research and development.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, and a kind of cell anoxia experimental facility at intermittence that can carry out intermittent hypoxia cell research is provided.
For achieving the above object, the invention discloses intermittently anoxia experimental facility of a kind of cell, comprise cell culture incubator and Tissue Culture Dish, it is characterized in that: described experimental installation is also provided with humidity conditioner, temperature-control device, oxygen source, carbon dioxide air source, nitrogen source of the gas and principal controller, described oxygen source, carbon dioxide air source, nitrogen source of the gas is connected with cell culture incubator through corresponding gas pipe line respectively, in described gas pipe line, be equipped with by-pass valve control, humidity conditioner described in described main controller controls, temperature-control device makes in cell culture incubator in constant temperature, humidity constant state, and by-pass valve control makes oxygen content periodical change between two states of height in cell culture incubator.
This device is owing to having temperature and humidity control device, make in the situation that gas frequently flows and exchanges, ensured the temperature, the humidity environment that in casing, maintain applicable Growth of Cells, and between two states of height, change formation cycle anaerobic environment by oxygen content in by-pass valve control periodic adjustment cell culture incubator described in main controller controls, it is constant that by-pass valve control keeps gas concentration lwevel simultaneously, create the intermittently environment of anoxic, carry out the research of intermittent hypoxia cell.
As the further setting of the present invention, this cell intermittently anoxia experimental facility also has a set of cellular control unit experimental installation, comprise control group culture dish and for measuring the dissolved oxygen meter of the dissolved oxygen concentration of contrast culture ware substratum, described dissolved oxygen meter detects according to the dissolved oxygen in culture dish, described dissolved oxygen meter output is connected with principal controller, the oxygen concentration of main controller controls control group remains on 21%, and gas concentration lwevel remains on 5%.
By contrast culture ware and dissolved oxygen meter are set, at any time by detecting the dissolved oxygen in contrast culture ware substratum, and detected result is delivered in principal controller and contrasted with set(ting)value, as depart from predetermined set value, control corresponding by-pass valve control and stablize the oxygen level of air in casing, measure and can not cause interference to the Growth of Cells in Tissue Culture Dish simultaneously.
As the further setting of the present invention, carbon dioxide content constant is 5% in described main controller controls casing, oxygen content 30% and lower than 1% between change.Keep carbon dioxide content constant, regulate separately oxygen to reach and regulate oxygen content in cell culture incubator, this regulative mode is fairly simple effectively; Oxygen content 30% and lower than 1% between, this is faster for what dissolved oxygen concentration in cell culture fluid was changed, and the state of anoxic at intermittence occurs in human body close to cell more.
As the further setting of the present invention, described humidity conditioner comprises the water storage tray that is arranged on described cabinets cavity bottom, described water storage tray below is provided with well heater, between described water storage tray top and Tissue Culture Dish, be provided with dividing plate by described water storage tray and Tissue Culture Dish place spatial separation, described dividing plate is provided with transom, the position of corresponding transom is slidably provided with for regulating the flashboard of the ventilative area of transom, and being provided with flashboard driving mechanism, described principal controller drives flashboard to slide by controlling flashboard driving mechanism.That the humidity conditioner of said structure has is simple in structure, it is convenient to control, effective advantage.
