  • the surgical mask 10 also functions to scavenge the gases exhaled by the patient.
  • the surgical mask 10 includes an oral mask 12 having a nasal mask 14 nested therein.
  • the oral mask 12 includes rigid or semirigid plastic shell 16.
  • the shell 16 defines a hollow chamber 36 having a rear-facing opening defined by a rim 18.
  • the rear-facing opening of the shell 16 is generally pear-shaped when viewed from the rear of the mask.
  • a pillow-type seal 20 is secured to the rim 18 of the shell 16.
  • the seal 20 is embodied as a soft, flexible, air-filled bladder, although other types of seals may also be used.
  • the seal 20 deforms to correspond with the contour of a patient's face when the doctor places the surgical mask 10 over the patient's nose and mouth.
  • the seal 20 envelops the area around the patient's nose and mouth in such a way as to create a seal between the oral mask 12 and the patient's face. In such a way, the patient's nose and mouth are sealed within the chamber 36.
  • a gas port 22 is defined in the shell 16 of the oral mask 12.
  • the gas port 22 includes a hollow tube 24 that extends outwardly from the oral chamber 36.
  • the hollow tube 24 has a proximal end that opens into the oral chamber 36.
  • a threaded distal end 28 of the hollow tube 24 may be coupled (e.g., screwed) to a hose or other type of fluid line of a scavenger circuit 72 (see FIG. 3).
  • the chamber 36 of the oral mask 12 may be exposed to the negative fluid pressure generated by the scavenger circuit 72.
  • a vacuum pump (not shown) associated with the scavenger circuit 72 may be used to evacuate the gases exhaled by the patient into the oral mask 12.
  • a vacuum pump (not shown) associated with the scavenger circuit 72 may be used to evacuate the gases exhaled by the patient into the oral mask 12.
  • the oral mask 12 also includes a number of holes 30 extending through the shell 16.
  • the holes 30 allow for minor venting of the chamber 36 of the oral mask 12 when it is subjected to negative fluid pressure from the scavenger circuit 72. This prevents the oral mask 12 from uncomfortably locking onto the patient's face due to the suction generated by the scavenger circuit 72.
  • the negative pressure in the chamber 36 of the oral mask 12 prevents exhaled gases from escaping through the holes 30.
  • One of a pair of strap mounts 32 is formed in the shell 16 of the oral mask 16 on either side of the port 22.
  • An elastic strap 34 is secured to the strap mounts 32 and may be used to secure the surgical mask 10 to the patient's head.
  • the oral mask 12 envelops the nasal mask 14. More specifically, the nasal mask 14 is located within the chamber 36 such that the chamber 36 envelops the nasal mask 14. When the surgical mask 10 is placed over the patient's face, the seal 20 also functions to seal the nasal mask 14 within the chamber 36.
  • the nasal mask 14 includes rigid or semi-rigid plastic shell 50.
  • the shell 50 defines a hollow chamber 54 having a rear-facing opening defined by a rim 52.
  • the rear-facing opening of the shell 50 is generally pear-shaped when viewed from the rear of the mask.
  • a flexible seal 56 is secured to the rim 52 of the shell 50.
  • the seal 56 is embodied as a soft, flexible sealing ring, although other types of seals may also be used.
  • the seal 56 corresponds with the contour of a patient's nose and the area of the face surrounding the nose when the doctor places the surgical mask 10 over the patient's nose and mouth.
  • a gas port 60 is defined in the shell 50 of the nasal mask 14. Although only one gas port 60 is shown in the illustrative embodiment described herein, it should be appreciated that any number of gas ports may be used. Moreover, the gas port 60 (or ports) may be located at various locations in the shell 50 to fit the needs of a given design.

  • the hollow tube 62 has a proximal end 64 that opens into the nasal chamber 54.
  • a distal end 66 of the hollow tube 62 may be coupled to a hose 68 or other type of fluid line of a medical gas administration circuit 70 (see FIG. 3).
  • the chamber 54 of the nasal mask 14 may be exposed to the medical gases (e.g., anesthesia gases or oxygen) supplied by the gas administration circuit 72.
  • a supply pump (not shown) or pressurized tank (not shown) associated with the gas administration circuit 70 may be used to supply medical gases under positive pressure to the chamber 54 of the nasal mask 14 where such gases are then inhaled by the patient through the patient's nose.
  • the distal end 66 of the hollow tube 62 is herein described as being slip fit onto the hose of the gas administration circuit 70, it should be appreciated that other configurations may also be used to couple the nasal mask 14 to the gas administration circuit.

  • the gas administration circuit 72 can accumulate within the chamber 54 of the nasal mask 14 to be inhaled by the patient without being evacuated by the scavenger circuit 72 through the oral mask 12.
  • a pair of curved indentations 58 are formed in the rear edge of the flexible seal 56 near the portion of the seal 56 that engages the bridge of the patient's nose.
  • the curved indentations 58 provide for a minor amount of selective fluid communication between the chamber 54 of the nasal mask 14 and the chamber 36 of the oral mask 12. Specifically, if the patient exhales heavily through his or her nostrils, the nasal mask is gently urged away from the bridge of the patient's nose. This allows the exhaled gases exiting through the patient's nostrils to pass from the chamber 54 of the nasal mask 14 into the chamber 36 of the oral mask 12 through the opening created by the space between the curved indentations 58 and the patient's nose.
  • the surgical mask 10 may be positioned over the patient's nose and mouth to administer medical gases such as anesthesia gases to the patient.

  • the holes 30 formed in the shell of the oral mask 12 prevent the oral mask 12 from locking onto the patient's face due to the suction created by the negative pressure. Moreover, to the extent the patient exhales heavily out of his or her nostrils, the curved indentations 58 of the nasal mask 14 provide a fluid path that allows the exhaled gases from the patient's nostrils to pass from the nasal chamber 54 into the oral chamber 36 where they are scavenged along with the gases exhaled from the patient's mouth.
  • the gas administration circuit 70 (or other gas source) may be operated to supply recovery gas, such as oxygen, to the patient via the hollow tube 62 of the mask's gas port 60.
  • the patient will continue to outgas the anesthesia gases administered to the patient during the surgical procedure.

  • the hollow tube 24 of the gas port 22 is coupled to the hose of the scavenger circuit 72.
  • the scavenger circuit 72 creates negative pressure in -l ithe chamber 36 of the oral mask 12. This negative pressure pulls gases exhaled from the patient's mouth out of the surgical mask 210 and into the scavenger circuit where they are processed and disposed.
  • the gas administration circuit 70 may be operated to supply recovery gas, such as oxygen, to the patient via the hollow tube 62 of the mask's gas port 60.
  • recovery gas such as oxygen
  • the patient will continue to outgas the anesthesia gases administered to the patient during the surgical procedure.
  • the scavenger circuit 72 continues to create negative pressure in the chamber 36 of the oral mask 12 thereby allowing the exhaled gases from the patient's mouth to be pulled from the surgical mask 210 during post-operative recovery.
  • FIGS. 9 and 10 a different embodiment of a surgical mask is shown (hereinafter referenced as a surgical mask 310).
  • a surgical mask 310 Some features of the embodiment illustrated in FIGS. 9 and 10 are substantially similar to those discussed above in reference to the embodiments of FIGS. 1-8. Such features are designated in FIGS. 9 and 10 with the same reference numbers as those used in FIGS. 1-8.

  • the nasal mask 14 of the surgical mask 310 does not have a seal secured to its rim 52.
  • the oral mask of a given design of the surgical masks described herein may include the seal or be designed without it.
  • the bulk of the anesthesia and/or recovery gases delivered to the nasal mask 14 is inhaled by the patient with a small amount of such gases leaking around the rim of the nasal mask where they are scavenged via the negative pressure in the chamber 36 of the oral mask 12 created by the vacuum pump of the scavenger circuit 72.
  • the nasal mask 14 of the surgical mask 310 is used to create a local concentration of anesthesia and/or recovery gases that is sufficient to create the desired efficacy despite a portion of such gases being drawn directly into the scavenger circuit 72.
  • the gas port 22 of the oral mask 12 and the gas port 60 of the nasal mask 14 of the surgical mask 310 have been altered relative to the designs of FIGS. 1-8 to accommodate the use of a dual-lumen tubing design.
  • the tubes connecting the surgical mask 310 to the gas administration circuit 70 and the scavenger circuit 72 are embodied as a dual-lumen tube.
  • the gas line 68 coupled to the gas administration circuit 70 extends through and is positioned within the gas line 168 coupled to the scavenger circuit 72.
  • a number of sidewalls 170 extend between the outer gas line 168 and the inner gas line 68 of the dual-lumen tube to maintain its structure.
  • the use of the dual-lumen tube allows a single tube to be coupled to the surgical mask thereby facilitating its use.
  • the hollow tube 62 of the nasal mask's gas port 60 is positioned within the bore of the hollow tube 24 of the oral mask's gas port 22.
  • FIG. 11 a different embodiment of a surgical mask is shown (hereinafter referenced as a surgical mask 410).

  • the surgical mask 410 is similar to the surgical mask 310 of FIGS. 9 and 10 with the exception of the design of the inner mask 14.
  • the inner mask 14 of the surgical mask 410 is positioned to deliver anesthesia and/or recovery gases to the patient's mouth instead of the patient's nose. Gases exhaled by the patient are captured and scavenged by the outer mask 12 in the manner herein described in regard to the surgical masks 10, 1 10, 210, 310.
  • the surgical mask 410 finds particular use in surgical procedures related to the nose in which the nose is "packed" or otherwise rendered unusable for the inhalation of gas.
  • a further modification to any of the surgical masks 10, 1 10, 210, 310, 410 includes the use of a viral filter.
  • the surgical masks 10, 110, 210, 310, 410 may be embodied to include one or more viral filters to prevent the spread of viruses or other biological organisms/contaminants from the surgical mask.
  • a filter may be placed proximate to the gas port(s) of the surgical mask to prevent the spread of viruses or other biological organisms/contaminants to the tube(s) connecting the surgical mask to the gas administration circuit 70 and the scavenger circuit 72 thereby allowing such tube(s) to be reused.
  • a single viral filter may be used to filter both lines.
