Chitra Acrylosorb Secretion
The material titled Chitra Acrylosorb Secretion Solidification System
has been developed by Scientists at Sree Chitra Tirunal Institute for
Medical Sciences and Technology (SCTIMST).
Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST)
is an autonomous institute under the Department of Science and Technology
(DST), Govt of India.
The material titled Chitra Acrylosorb Secretion Solidification System’
is a highly efficient superabsorbent material for liquid respiratory and
other body fluid solidification and disinfection.
This has been developed for the safe management of infected respiratory
secretions. Acrylic Sorb can absorb liquids at least 20 times more than its
dry weight and also contains a decontaminant for in situ disinfection.
Containers filled with this material will immobilize the contaminated
fluid by solidifying it (gel-like), thus avoiding spillage and will also
disinfect it. The canister containing the solidified waste canister can then
be decomposed as all other biomedical waste by incineration.
In the developed system, suction canisters, disposable spit bags have
been designed with “Acrylic Sorb” technology. They are lined inside with the
AcryloSorb material. The AcryloSorb suction canisters will collect the
liquid respiratory secretions from ICU patients or those with copious
secretions treated in the wards.
The container will be spill-proof and can be sealed after use, making it
safe and fit for disposal through the usual incineration system for
biomedical wastes. Sealable and disposable AcryloSorb spit bags are provided
for solidifying the sputum and saliva of ambulant patients with respiratory
infections, which can then be incinerated.
Generally, in the ICU, the secretions are sucked by a suction machine
into bottles or canisters, which have to be emptied when full, subjected to
a decontamination process in a sluice room and discarded through the waste
fluid disposal systems.
Apart from the re-contamination risk during the handling involved in
these processes, there is a need for well-equipped sluice rooms with
disinfection facilities, which can be an issue in less well-equipped
hospitals or makeshift isolation wards during epidemics.
This technology reduces the risk for the hospital staff, the need for
personnel for disinfecting and cleaning the bottles and canisters for
reusing them and makes the disposal safer and easier.
