Best ventilator equipment MSLVM12 for sale Technical Specification
MSLVM12 ventilator is a gas-driven, electrically controlled and multi-functional mechanism,
which incorporates time and capacity switches and pressure restrictions. The main purposes
of ventilator are to: provide the patients who are in a deadly danger with respiratory support at their
most dangerous stage; protect patients in going through their dangerous period; ensure a successful
basic treatment for further recovery; provide substitutes for anti-reversion respiratory muscle pathological
changes or anti-reversion upper windpipe injury to maintain the patients' breathing function; provide
breathing support for patients after sickness or during the recovery period after operation.
Main characteristics are stated as follows:
a．Gas-driven, electrical control, time-pressure switch, and pressure limit control
b．Have air-oxygen mixer particles of high-performance, can adjust the oxygen concentration
conveniently and accurately.
c．Apply electronic PEEP, can make continuous adjustment of PEEP.
d．PTR has 2 kinds of trigger ways: Pressure trigger and flow trigger.
e. Apply highly and fast sensitive pressure sensor and flow sensor to airway pressure, gas flow detection,
control and display, and has ventilation auto-compensation
f. Many ventilator modes: VCV, PCV. PSV, SIMV. PSIMV(SIMV＋PSV), CPAP.
g. Apply led, real-time displays these parameters, such as controlling frequency, tidal volume, ventilation,
total breathing frequency, self respiratory rate, compliance, airway resistance, oxygen concentration, it also
displays pressure and curve of flow vale to time.
h. P-V (Pressure-Volume), F-V (Flow-Volume).
i. When the ventilator runs abnormally or is incorrectly operated, it will trigger both audio and visual alarms
to protect itself.
j. even if the power is off, no chokes will occur to the patients, for the respiration tubes are connected to the
outer atmosphere.
Normal working conditions of PA-900B II:
_____Temperature: 10~40℃
_____Relative Humidity: ≤80%
_____Atmospheric Pressure: 86 kPa ～ 106 kPa
_____Gas: medical oxygen and compressed air of 280～ 600kPa
_____Power: AC220V±10%, 50±1Hz, 40VA, with ground protection.
?MSLVM12 ventilator is motivated by medical oxygen and compressed air. Under inspiratory phase,
two ways of compressed gases (compressed oxygen and air) enter air-oxygen commingler, forming
a gas mixtureof certain pressure that mixes medical oxygen, and then enter electronic controlled
inspirator rates valve of high performance, last do mechanical ventilation in the patient's respiration
tract through inhale tubes of ventilator; under expiratory phase, the patients exhale gas to the atmosphere
through filter, and expiration control valve of the expiration tubes. During this process, high-performance
rates control valve, highly sensitive flow sensor and pressure sensor and single-chip microcomputer
control system are adopted to bring airway pressure, airway flow speed closed-loop regulation, thus realize
Gas-driven, electrical control, time-pressure switch, and pressure limit control
NOTICE: This unit could work properly under the condition of medical oxygen and compressed air combining
together. Meanwhile, the pressure for the common gas should be the around 0.4MPa.
The ventilator will do real-time display of these following parameters:
_____Work mode and I/E ratio
_____ Pre-set controlling frequency
_____Tidal volume per respiration
_____The appearance of spontaneous respiration and its frequency
_____ Oxygen concentrator
_____ Plat form pressure and Airway peak pressure
_____ Compliance and airway resistance
_____Real-time changes of airway internal pressure
_____Display of Inspiratory status and Expiratory status, actual respiratory frequency
_____Ventilation capacity per minute
_____ Airway pressure, respiratory frequency, tidal volume, alarm bounds of Ventilation
capacity per minute.
The ventilator triggers alarms whenever abnormal situation occurs. For example, the ventilator will
trigger alarms when airway pressure is too low which may be caused by leakage or falling off. When
the airway pressure is too high which may be caused by the blockage of tubes, it will not only trigger
alarms automatically, but also transfer the ventilator from inspiratory status to expiratory status to
release the over-high pressure if the pressure keeps on rising.
