Canister for a mobile negative pressure wound therapy device

A canister for a mobile negative pressure wound therapy (NPWT) device associated with a user, the canister adapted to be in fluid communication with a wound site and capable of receiving fluids from the wound site, wherein the canister comprises:

• —an inner wall partially defining an inner volume of the canister, the inner wall having an inner surface, —an inlet port fluidly coupled to the inner volume of the canister at a first position, —an outlet port fluidly coupled to the inner volume of the canister at a second position, the second position being arranged at a preset distance from the first position, —a filter member arranged in a vicinity of the outlet port, —a liquid absorbent material arranged inside a portion of the inner volume of the canister, the liquid absorbent material adapted to collect a liquid from the wound site, and —a baffle arranged between the inlet port and the liquid absorbent material, wherein:
• —the canister further comprises a bypass member adapted to at least partly allow passage of air from the inlet port to the filter member, wherein the bypass member has a length and defines a channel formed as a recess in the inner surface of the inner wall, wherein the channel is in fluid communication with the liquid absorbent material along the length of the bypass member, wherein the inner wall comprises a peripheral sidewall portion and a bottom wall portion, wherein the bypass member extends along the peripheral sidewall portion and the bottom wall portion.

A mobile negative pressure wound therapy (NPWT) device associated with a user, comprising:

• —a housing, —a negative pressure pump arranged within the housing, —a canister having an inlet port and an outlet port, wherein the inlet and the outlet port are fluidly coupled to an inner volume of the canister, and the outlet port is fluidly connected to the negative pressure pump, wherein the inlet port is adapted to be fluidly connected to a wound cover, the wound cover provided for creating a sealed space defined in part by a wound site, —a battery arranged within the housing, the battery provided for powering the NPWT device, and —a control unit arranged within the housing, the control unit electrically connected to the battery and adapted to control an operation of the negative pressure pump to selectively establish a negative pressure within the sealed space, wherein the canister comprises:
• —an inner wall partially defining the inner volume of the canister, the inner wall having an inner surface, —a filter member arranged in a vicinity of the outlet port, —a liquid absorbent material arranged inside a portion of the inner volume of the canister, the liquid absorbent material adapted to collect a liquid from the wound site, and —a bypass member adapted to at least partly allow passage of air from the inlet port to the filter member, wherein the bypass member has a length and defines a channel formed as a recess in the inner surface of the inner wall, wherein the channel is in fluid communication with the liquid absorbent material along the entire length of the bypass member, wherein the inner wall comprises a peripheral sidewall portion and a bottom wall portion, wherein the bypass member extends along the peripheral sidewall portion and the bottom wall portion.
