Used ventilator machine MSLVM09 for sale
MSL Used ventilator machine MSLVM09 for sale Main Features
The MSLVM09 ventilator is an electrically controlled pneumatic ventilator integrating such functions as time,
volume cycling, pressure limit, etc. It is mainly intended for providing ventilation support to a critically ill patient
during the life threatening phase and ensuring the going-through of the dangerous period by the patient and
smooth treatment of primary diseases for recovery. Also it provides an alternation in case of irreversible lesions
in respiratory muscles or irreversible damage to upper airway to maintain the respiratory function of the patient,
and also provides ventilation assistance for the patient during the recovery from a disease or operation. Its main
features are as follows:
A.Gas drive and electrical control, time-pressure switching and pressure limit control.
B. A high-brightness LED digital display is used to present the control frequency, tidal volume, throughput, overall
respiratory rate, spontaneous breathing frequency, etc.
C.A highly sensitive and responsive pressure sensor and a flow sensor are used to measure, control and display
the airway pressure and gas flow rate and the ventilator is equipped with automatic throughput compensation.
D.In case of an abnormality to the ventilator or misoperation, the ventilator can raise a visual-audible alarm to
automatically protect itself.
Cheap ventilator machine MSLVM09 for sale Requirements for Ambient Conditions
The MSLVM09 ventilator is a mobile medical device as specified in the Environment Requirements and Test
Methods for Medical Electrical Equipment to operate in Climatic Environment Group II and Mechanical Environment
Group II. Its normal operating conditions are as follows:
——Ambient temperature: 10 ～ 40℃, relative humidity: no higher than 80%.
——Atmosphere pressure: 86kPa ～ 106kPa
——Gas source requirement: medical oxygen source with a pressure ranging from 280 to 600kPa and a flow rate
of 50L/min (containing no fresh air).
——Power supply requirements: AC 220V±10%, 50±1Hz and 30VA, well grounded.
Best ventilator machine MSLVM09 for sale Operating Principles
Driven by compressed medical oxygen, the MSLVM09 ventilator uses a gas ejector based on Venturi effect to
form a mix of medical oxygen and ambient atmosphere which is delivered through the ventilator circuit into the
airway in the patient for mechanical ventilation. During such process, a fast solenoid valve, a highly sensitive
flow sensor, a pressure sensor and a single-chip microcomputer control system are used to measure, adjust
and control such parameters as the ventilation pressure, ventilation time, throughput, etc. to the patient.
This ventilator can display in real time the following important parameters:
——Operating mode and respiratory rate;
——Ventilator control frequency set by medical staff;
——Tidal volume of each breath in the patient;
——Occurrence of spontaneous breath in the patient and spontaneous breathing frequency;
——Expiratory phase and inspiratory phase and actual respiratory rate;
——Setting and adjustment of inspiration triggering pressure, PEEP, and highest airway pressure;
——Real-time variation in internal airway pressure.
This ventilator is capable of raising an alarm in case of abnormality. For example, the ventilator can
automatically alarm in case of too low airway pressure due to the gas leak in the tube or tube separation.
In case of too high tube pressure caused due to the tube blockage, it not only can raise an alarm but also
automatically switch to the expiratory phase if the pressure further rises to release the too high pressure.
