  2. The fluid collection system of claim 1, wherein at least a portion of the aperture is formed in a notch (2141) proximate the open end of the canister (2100).
  3. The fluid collection system of claim 2, wherein at least a portion of the aperture is formed in the canister (2100), the lid (2200), or both the lid (2200) and the canister (2100).
  4. The fluid collection system of claim 3, wherein at least a portion of the notch (2141) is formed in a sidewall portion (2121, 2122, 2123, 2124) of the canister (2100).
  5. The fluid collection system of claim 1, wherein an interstitial vacuum port (2170) is positioned on the canister (2100).
  6. The fluid collection system of claim 5, wherein the interstitial vacuum port (2170) is positioned on a sidewall portion (2121, 2122, 2123, 2124) of the canister (2100).
  7. The fluid collection system of claim 5, wherein the interstitial vacuum port (2170) is connected to a vacuum source (2700), wherein the interstitial chamber (2001) is in fluid communication with both the vacuum source (2700) and the fluid chamber (2002), and wherein the interstitial chamber (2001) is positioned between the vacuum source (2700) and the fluid chamber (2002).
  8. The fluid collection system of claim 5, wherein the interstitial vacuum port (2170) is connected to a vacuum source (2700) and wherein the fluid chamber (2002) is in fluid communication with the vacuum source (2700) through the interstitial chamber (2001).
  9. The fluid collection system of claim 1, wherein the lid (2200) and the canister (2100) form a sealing arrangement around the fitment assembly (2400) when the fitment assembly (2400) is positioned within the aperture and when the lid (2200) and the canister (2100) are in the closed position.
  10. The fluid collection system of claim 9, wherein at least a portion of the lid (2200) forms a sealing arrangement with at least a portion of the fitment assembly (2400) when the fitment assembly (2400) is positioned within the aperture and when the lid (2200) and the canister (2100) are in a closed position.
  11. The fluid collection system of claim 1, wherein the at least one fluid port (2450) is in fluid communication with the vacuum source (2700), sequentially, through the fluid chamber (2002), through the fluid chamber vacuum port (2440) and through the interstitial chamber (2001).
  12. The fluid collection system of claim 1, wherein the fitment assembly (2400) includes a filter (2560) positioned adjacent to the fluid chamber vacuum port (2440).
  13. The fluid collection system of claim 1, wherein a fitment (2560) of the fitment assembly (2400) includes a protrusion (2420) around which the aperture forms a sealing arrangement when the fitment assembly (2400) is positioned within the aperture and when the fluid collection system (2000) is in the closed position.

Description

BACKGROUND Hospital operating rooms, emergency rooms, and other healthcare facilities generate a large volume of liquid waste, which may include irrigation liquids and secretions removed from a patient's body (e.g., blood and other bodily liquids). To collect and dispose of such liquid waste, suction canisters are typically used. A typical suction canister is a temporary storage container that uses suction to create a negative pressure inside the canister to drain liquids or secretions from the patient's body. After each medical procedure (e.g., surgery), the canister containing the liquid waste is transported to a utility area to be disposed of as red-bag waste or to be emptied, cleaned, and disinfected for reuse. A new or cleaned canister is then brought into the operating room for a next medical procedure. Most conventional fluid collection systems with a liner include two components: a canister and a liner assembly. The canister is closed by a lid. The lid is attached to the liner, such that the liner assembly includes both the liner and the lid. The canister is typically cleaned after a procedure and used again, while the liner assembly is a single-use component. The liner and the lid are both discarded after a procedure. Hospitals pay for red-bag waste disposal by weight, so it is desirable to limit the material usage in the disposable components. A prior art device is disclosed in US 6,056,730. SUMMARY The invention is defined by the appended claims. Any disclosed methods do not form part of the invention as claimed. Disclosed herein is a fluid collection system comprising a canister having a cavity and an open end; a lid, the lid sealed with the open end of the canister when the fluid collection system is in a closed position; and a fluid receptacle comprising a liner and a fitment assembly, the liner and the fitment assembly together defining a fluid chamber, wherein the fitment assembly is sealed with the lid around an opening in the lid when the fluid collection system is in the closed position. Also disclosed herein is a fluid receptacle for use in a fluid collection system including a canister having a lid, the fluid receptacle comprising a liner having an opening; and a fitment assembly comprising a fluid port; a fluid chamber vacuum port; and a sealing surface, wherein the fitment assembly is sealed to the liner around the opening; wherein the liner and the fitment assembly together define a fluid chamber, wherein the fluid port and the fluid chamber vacuum port allow communication into and out of the fluid chamber, and wherein at least a portion of the sealing surface seals to the lid. Also disclosed herein is a fluid collection system comprising a canister having a cavity and an open end; a lid, the lid forming a seal with a portion of the open end of the canister when the fluid collection system is in a closed position; and a fluid receptacle comprising a liner and a fitment assembly, the liner and fitment assembly together defining a fluid chamber, wherein the lid and the open end of the canister define an aperture between them when the fluid collection system is in the closed position, and wherein the fitment assembly seals around the aperture when the fluid collection system is in the closed position. Also disclosed herein is a method of collecting fluid in a fluid collection system, the method comprising providing a fluid collection system comprising: a canister; a lid having an opening; and a fluid receptacle comprising a liner and a fitment assembly, wherein the liner and fitment assembly define a fluid chamber, and wherein the fitment assembly includes a fluid port and a fluid chamber vacuum port; forming a seal between the fitment and the lid and a seal between the canister and the lid to define an interstitial chamber; applying a vacuum to the interstitial chamber; and transmitting the vacuum from the interstitial chamber to the fluid chamber through the fluid chamber vacuum port; and drawing a fluid into the fluid chamber through the fluid port.
