According to GlobalData’s company profile on Hollister, ostomy monitoring system was a key innovation area identified from patents. Hollister's grant share as of September 2023 was 57%. Grant share is based on the ratio of number of grants to total number of patents.

A recently filed patent (Publication Number: US20230301816A1) describes a bacteria formulation designed to neutralize odors, particularly hydrogen sulfide and methyl mercaptan. The formulation includes odor neutralizing bacteria, which are chemotrophic bacteria, and one or more compounds that support the viability of the bacteria. The patent lists several specific types of odor neutralizing bacteria that can be used in the formulation, including Thiobacillus sp., Thiobacillus denitrificans, Thiobacillus ferrooxidans, Thiobacillus thiooxidans, Thiobacillus novellus, Thiobacillus thioparus, Thermothrix azorensis, Thiothrix nivea, Thioalkalispira microaerophila, and Thiomicrospra frisia. The compounds that support the viability of the bacteria can include nutrients, buffering agents, and supplements. The bacteria formulation may also include photosynthetic bacteria and Beggiatoa spp. Additionally, probiotic bacteria can be added to provide an antimicrobial effect. Examples of probiotic bacteria mentioned in the patent are Lactobacillus spp, Lactococcus, Leuconostoc, Bifidobacterium, and Saccharomyces. The bacteria and compounds in the formulation interact to maintain a pH range of about 2-3 or about 6-8.

The patent also describes an ostomy system that incorporates the bacteria formulation. The ostomy system includes an ostomy pouch with opposed sidewalls that form an enclosed area for storing stomal effluent. The pouch is equipped with a pouch filter connected to one of the sidewalls. The ostomy appliance, which is adhered to the user's skin, is part of the system. The bacteria formulation, consisting of odor neutralizing bacteria and compounds for supporting their viability, is included in the ostomy system. The formulation can be placed in the enclosed area of the ostomy pouch or incorporated into the pouch filter. Notably, the pouch filter does not contain activated carbon. In addition to odor neutralizing bacteria, the bacteria formulation for the ostomy system can also include probiotic bacteria for their antimicrobial properties. The patent suggests that the bacteria formulation can be integrated into various components of the ostomy system, such as the pouch film, comfort panel, and skin-contacting adhesive of the ostomy appliance. The specific types of odor neutralizing bacteria and probiotic bacteria mentioned in the patent are the same as those listed for the bacteria formulation.

In summary, the patent describes a bacteria formulation designed to neutralize odors, particularly hydrogen sulfide and methyl mercaptan. The formulation includes odor neutralizing bacteria, compounds for supporting their viability, and optionally, photosynthetic bacteria and Beggiatoa spp. The bacteria formulation can be used in an ostomy system, where it is incorporated into the ostomy pouch or pouch filter. The ostomy system may also include probiotic bacteria for their antimicrobial effects. The patent lists specific types of odor neutralizing bacteria and probiotic bacteria that can be used in the formulation and ostomy system.
