Advanced ventilator equipment MSLVM12 Main Characteristics

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.

Cheap ventilator equipment MSLVM12 for sale Structure and work principle

•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.
