The Function of Medical Ventilator

Ventilator is a tool to implement mechanical ventilation; it has been widely used in clinical anesthesia and ICU, and improves the patient's oxygenation and ventilation, reducing the work of breathing, respiratory and circulatory support functions, as well as treatment of respiratory failure. As early as in 1796, Herholar and Rafn had a special report that the application of artificial respiration method enables to saving drowning patient, 1929 Drinker and Shaw successfully developed the automatic iron lung. Until around World War II, has gradually understood the principles of mechanical ventilation and respiratory support for post-cardiothoracic surgery. 1952 Scandinavia polio epidemic, more than four months in the hospital for treatment of Copenhagen 2722 patients, of which 315 required respiratory supports, Ibson emphasize respiratory support Aikido management, the overall mortality rate from 87 % to 30%. Since then people have realized the importance of mechanical ventilation. Thus various types of ventilator came out gradually, especially in recent years, with the ventilator in the field of micro-computer technology; the ventilator has been the rapid development of technology, performance gradually improved.
Currently, the medical ventilator machine type and model is very much to use a different approach. But no matter how ventilator product type and model improve and update its therapeutic effect substantially the same as its treatment effects include: to improve the ventilation, improve the ventilation function and reduce power consumption and save breath cardiac reserve capacity.

1, To improve the Breathing system:
This is the basic therapeutic effects of medical Portable anesthesia machine. Before linking the ventilator, the general should be endotracheal intubation or tracheotomy to maintain airway patency. When the normal frequency ventilation and reasonable positive pressure breathing convection can achieve adequate tidal volume, the number of mechanical ventilation may also need to be adjusted in order to maintain adequate ventilation to ensure that the needs of patients. HFV use high frequency diffusion and convection airflow to promote.
2, to improve the aeration function:
In recent years, due to the development of a deep understanding of respiratory physiology and ventilator research, using some special ventilation mode at the ventilator therapy(hot sale anesthesia machine), such as PEEP respiratory, expiratory extended by inspiratory time, inspiratory hold etc., improved pulmonary gas partial pressure of oxygen and the uneven distribution of ventilation flow imbalance, reduce pulmonary shunt, thus improving aeration function, improve the arteries. Current treatment range from simple ventilator dysfunction developed to the serious dysfunctions ventilation disorders, such as adult respiratory distress syndrome.
3.Reducing the breathing system consumption, saving cardiac reserve capacity:
Ventilator can reduce the load respiratory muscle action to reduce oxygen consumption, improve hypoxia help to restore and respiratory muscle fatigue, but also it’s very significantly to reduce the load on the heart, which after thoracic surgery patient’s recovery is particularly important.

Which are the transmission of the virus?

How does the bird flu transmit to human?

The contact infection is the main transmission for the bird flu.

1.The bird flu virus can enter the body through the digestive tract and respiratory tract.

2.Direct contact with quite a number of the products of the virus,like the waste,feather,respiratory secretions,blood from poultry.Also it will be infected by the eye conjunctiva and abraded skin.

3.Only the poultry meat is cooked enough,then the virus can be killed.If the poultry meat is not cooked enough,the virus will be transmitted to the human.So if you have eaten the untested poultry or the poultry from the outbreaks area,then you may be infected.

4.When you buy the live chicken,please make sure the chicken is healthy,not the sick one.

Seldom sick poultry can survive,but they will excrete waste containing the virus in at least 10 days.Otherwise,the wings of the chicken may hide the virus,so when the chicken flapping the wings,it may release the virus.

WILL THE BIRD FLU BE TRANSMITTED BETWEEN PEOPLE?

1.For now,it is only seen the case that the bird flu transmit from poultry to people.That means it has no evidence to prove the bird flu will be transmitted between people.

2.While in theory,if the virus variants,then it may be be transmitted between people.

HOW TO PREVENT THE BIRD FLU?

Because there is no corresponding vaccine and the spring is season of acute respiratory illness,so
The healthy life style is meaningful to prevent the illness.We should exercise more and avoid over exertion.No smoking.

1.Don't go to the outbreaks area of the bird flu.

2.When the virus occur,don't contact the poultry.After contacting the poultry,remember to clean up the hand with hand sanitizer.

3.Cook the chicken and other poultry meat enough.

4.Keep the room airy,don't go to the area of poorly ventilated.

5.Pay attention to the personal hygiene,the mouth and nose shall be covered when sneezing or coughing.

6.Keep the room clean,use the easy cleaning floor mats.

Medical electrical equipment like ventilators must comply with EMC(electromagnetic compatibility) STANDARDS starting next year.

Medical electrical equipment like ventilators security upgrades must comply with EMC STANDARDS starting next year,which involves more than 10,000 products.


The reporter learned from The national food and drug supervision and administration and the party's style to build a clean government work conference that beginning from Jan.1st,2014,medical electrical equipment such as cardiac pacemakers,Ventilator equipment should meet EMC Standard,in purpose to ensure patients'safety in use.


Along with the wide application of electrons and Information Technology in medical electrical equipment,and rapid development of new communication technology(Personal Communication System,cellular ect.) in various fields of social life,the medical electrical equipment not only launch electromagnetic energy itself but also be disturbed by electromagnetic energy from other communication devices around,thus causing damage to patients.Therefore,developed countries enforce compliance of the electromagnetic compatibility test standard in forms of regulations one after another.For example,the EU have enforced the relevant medical electrical equipment electromagnetic compatibility test standard since 1998.





To ensure patients'safety use better,the NFDA and the national medical appliance standards technical committee drafted and released YY0505-2012 Standards for medical devices industry "Part 1~2 of Medical electrical equipment: General requirements for safety and EMC requirements and testing standards",which will be put into implementation from January 1,2014 on.


Director of Medical Devices Supervision Department (which is affiliated with NFDA) Wang Lanming said this standard will involve about 11,000 medical equipments electrical products produced by three or four thousands of medical device manufacturing enterprise domestic and overseas.The implementation of the standard can help to develop the safety and validity of medical electrical equipments and prevent products which don’t conform to the EMC standards into the Chinese market.At the same time,it helps us be in line with international standards,make import and export trade convenient,thus promoting the development of medical device industry in our country.


To guarantee the smooth implementation of the standard,the National Bureau has been clear about the specific requirements and time schedules.From Jan.1st,2014 on,they must submit the relevant test report issued by medical device testing institutions when first registering class Ⅲ medical electrical equipment.Currently,medical equipment quality supervision and inspection centers in Beijing,Shanghai,Guangzhou,Tianjin,Hangzhou and Wuhan,along with medical device testing institutions such as medical device testing centers in Jiangsu and Shenzhen have acquired qualification to contract the standard,which provides strong technical support to carry out the EMC test according to the relevant requirements.


The reporter also learnt from the conference that the National Bureau is going to strengthen the construction of medical instrument standard and testing system,establish and revise 105 standards for cheap medical instrument and strengthen the supervision and review of medical instrument testing institutions.

Choose suitable transducer to improve the efficiency,accuracy and reliability of Sleep apnea machine.

Sleep apnea is called snoring,which is a disease troubling many people and affects their sleep badly.It is a challenge for medical device manufacturers to cure this disease.In this paper,based on the solution to this problem,we analyzed kinds of transducer solutions uesd in sleep-related breathing equipment and explained the differences among them,Ventilator equipment which provides valuable technical ideas for manufacturers. 
Sleep apnea syndrome(snoring),which worries millions of patients heavily,refers to breath stop during sleep which can appear repeatedly to a frequency of hundreds of times per night and to a time length of one minutes or more per time.Snoring may leads to memory deterioration and weight imbalance,even hypertension,cardiovascular and cerebrovascular diseases if leave it alone.Besides,the sleep insufficiency and fatigue caused by snoring may turn into the culprit behind inductrial injury accidents and motor vehicle traffic accidents 
 
One commonly used method of treatment is using PAP.Patients wear a Special mask when sleeping,which press some air into their Nostrils to prevent Suffocation.There are 3 forms of PAP: 
*CPAP(continuous positive pressure ventilator)provides definite stressed air continuously.This positive pressure can prevent UAO caused by upper airway collapse,which enables patients to breathe freely in case of apnea 
*Auto-PAP(automated positive pressure ventilator),can measure the resistance when breathing and adjust the air supply pressure by the magnitude of the resistive force to make sure every breath unimpeded. 
*Bilevel PAP(bilevel positive pressure ventilator)provides two kinds of pressure:suction of positive pressure and exhalation of positive pressure. 
The Portable ventilator machine detect the respiratory cycle via a gas mass flow sensor,which comforts patients more.Thus,it's more frequently used than those without this function. 
The gas mass flow sensor used in the sleep apnea machine must be equipped with high resolution and accurate sensing ability,so that it can sense the weak air change and control the MAF given to patients more accurately.Such sensors should measure the MAF more precisely and at the same time,sense the existence of air flow. 
Another important consideration is power dissipation.Lower power dissipation makes it possible for the respirator to be powered by battery,which promises more flexibility to the patients 
Ultimately,the noise produced by motor of the apnea machine should be controlled when patients try to sleep,which is important.It conflicts with the purpose of the Anesthesia Equipments when the noise affects patients' sleep. 
It's difficult for the motor to work if the sensitivity of pressure drop (pressure drop equals to he resistance of sensor) is too high.Thus a gas mass flow sensor and relatively low pressure drop is needed,or else it will add noise and reduce the motor's working life.
