Context: Canister bag that solidifies infectious secretions like COVID 19can save health workers from exposure during handling.

Infectious secretions from contagious diseases such as COVID 19, tuberculosis (TB), and influenza poses high risk for healthcare workers. Their exposure to the high-risk hazard while handling the waste can soon be controlled with a canister bag that solidifies the secretions rapidly, making disposal safer.

For the safe management of infected respiratory secretions, the researchers at Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), an autonomous institute under the Department of Science and Technology, Govt of India,

• Have come up with a method for safe handling and disposal of respiratory secretions in hospitals for ICU patients or those with copious respiratory secretions treated in the wards.

They have developed canister bags lined with super-absorbent material containing an effective disinfectant, named “AcryloSorb”.


  • It can absorb 500 ml of secretions and solidify it immediately.
  • In addition to that, the whole system will be decontaminated within no time because of the presence of disinfectant.
  • The liner structure has a patented design which allows the progressive absorbent availability upwards.
  • Solidification and immediate disinfection that occurs inside these bags eliminate risk of secondary infections by avoiding spilling and aerosol  formation, and thereby protect healthcare workers and promote safe workplace management.
  • Canister bags are enclosed in a customizable sealer bag which can pack it as spill-proof decontaminated biomedical waste disposable through incineration.
  • The product has been tested as per the international standards.
  • The approximate cost will be Rs. 100/- for each canister liner bag.
