■Sputum Collection Booth　VCM-1500N２

Although sputum examination is extremely important for a diagnosis of tuberculosis and evaluation of the outcome, airborne droplets generated at sputum collection should be prevented.


　　　

model VCM-1500N2


■Features

  • Keeping the booth negative pressure prevents the aerosol generated at sputum collection from leaking out to the environment.
  • Ventilation of 250 times/hour keeps the booth clean.
  • Laminar air flow from the ceiling of the booth does not cause air entrainment, back-flow, or retention inside the booth.
  • Air is supplied through a conventional HEPA filter, and exhausted through a HEPA filter treated with bactericidal enzymes.
  • After use, inside the booth is disinfected with an UV lamp.

■Sputum Collection Booth　VCM－780N2

Tuberculosis (TB) is spread through the air when people who have an active TB infection cough, sneeze, or otherwise transmit their saliva through the air. To prevent the spread of TB, isolation of the patient or special ventilation is required. The sputum collection booth has been developed to prevent TB from spreading while collecting sputum, by keeping the booth under negative pressure, cleaning the exhaust air with HEPA filters, and radiating UV light.


  • Small-footprint model that can easily be installed in the corner of a waiting room.
  • Inexpensive model with simple functions and operations
  • Ventilation frequency of 250 times/h
  • Prompt removal of contaminated aerosol from the booth.
  • Negative pressure indication light at the front panel allows you to easily confirm the internal pressure.
  • Prevents the aerosol generated while sputum collection from spreading by keeping the pressure negative.
  • A HEPA filter with bactericidal enzymes is equipped in the exhaustion side.
  • Prevents the contaminated aerosol from spreading through the exhaustion side.
  • The body is coated with melamine resin (antibacterial coating) suitable for preventing bacterial adherence.
  • The front door has a see-through window (frosted glass) that allows you to know about the situation in the booth.
  • An ultraviolet germicidal lamp is installed in the booth. It is equipped with an interlock unit to prevent turning on UV light while a patient is in the booth, by using a photo sensor. The UV light automatically turns off 2 hours after lighting.
