The device has the advantages of simple structure, convenient operation and small space occupation, and the position of the suction cover can be randomly regulated. The device is suitable for modifying a monitoring type ambulance to a negative pressure ambulance, suitable to be used at worktables of a biochemistry laboratory and a laboratory, suitable for curing infectious patients with high pathogenicity in infectious hospitals, suitable for inspecting unknown pathogens in labouratories of all hospitals, and suitable for checking and testing unknown infectious objects in execution departments such as troops, armed police and governments.
Description
Technical field
This utility model belongs to negative pressure speed and inhales device, and the negative pressure speed that prevents cross infection that is specifically related on a kind of vehicle is inhaled device.
Background technology
At present, domestic curing the disease property of height or strong virus force patient are when transporting treatment, usually in ambulance medical chamber, adopt exhaust fan and exhaust blower, outside the in line medical chamber that has, the simple and easy filtration of the process that has back is got rid of out of my cabin, and exhaust fan and exhaust blower are limit because of the installation position, generally are placed in from patient place far away, add that exhaust fan and exhaust blower flow are less, pressure head is low, fan, blower fan uptake and speed all do not reach requirement, and patient and medical personnel's breathe air are all in same laminar flow, can't stop cross infection, this car does not have negative pressure substantially under current intelligence, air-flow forms countless eddy current and dead angle, has strengthened cross infection.
Summary of the invention
The object of the present invention is to provide a kind ofly to take up room for a short time, the negative pressure speed that prevents cross infection that can form negative pressure in the part is inhaled device, to address the above problem.
The technical solution of the utility model is: the negative pressure speed that prevents cross infection is inhaled device, it comprises airduct, filter that connects on the airduct and induced-draught fan, the speed that is articulated and connected on the airduct is inhaled the arm pipe, speed is inhaled the arm pipe and is connected first universal joint, first universal joint connects second universal joint, and second universal joint connects suspended hood.
This device has simply, and the position of energy regulated at will suspended hood is extremely easy to use; In monitoring type ambulance medical chamber, the middle part suitable location of one side is installed this device, the negative pressure speed that prevents cross infection is inhaled device, it is draw gas in the medical chamber that negative pressure speed is inhaled device, filtering the back through high efficiency particulate air filter discharges out of my cabin, the medical chamber internal pressure is lower than pressure out of my cabin, cause to form the negative pressure working environment, air is a directed flow in the medical chamber, and negative pressure speed is inhaled the device oral area and realized barometric gradient, the high sexually transmitted disease people that cures the disease, one advances medical chamber, and medical personnel inhale the device air-suction cover with speed and move to patient head, patient respiration, the very fast absorption of pathogen that cough and health carry, discharge out of my cabin through filtering the back, effectively stoped doctors and patients' cross infection.
The rotatable 90 movable joint heads of spending that this device is connected with airduct by negative pressure speed induced-draught fan, airduct, universal joint, high efficiency particulate air filter, vacuum control system and drain tap constitute.Negative pressure speed induced-draught fan is arranged on the end of this device, and air sucks from air-breathing oral area, through universal joint, by airduct, directly goes into the movable joint head, filters the back to efficient filter and discharges out of my cabin.This device negative pressure speed induced-draught fan, the pressure head height, flow is big, flow velocity is fast.This negative pressure device air-suction cover oral area is near patient head, and is nearest with pathogen, and the pathogen infection body of virus that patient body carries and exhalation sucks fast and gets rid of medical chamber in this negative pressure device, makes the virus of pathogen can't stop and leave the space of cross infection.Medical personnel and patient respiration gas is not in same laminar flow.The vacuum control system of this device, employing be two closed loop control modules, it is constant to remain negative pressure value static in the ambulance medical chamber, dynamically the time.
This device is adapted to monitoring type ambulance and repacks negative pressure ambulance usefulness into, the workbench place that is used for biochemicals laboratory, laboratory, be adapted to curing the disease property of the treatment high infectiousness patient of infectious hospital, be applicable to the place of the not clear pathogen of all hospital's laboratory checks, be adapted to army, People's Armed Police and government and respectively hold energy department, check, the not clear place of infecting object of chemical examination.
