Respiratory protection system for surgery

Abstract

A respiratory protection system for use during surgery. The respiratory protection system may be a powered air purifying respirator, a supplied air respirator, or a self-contained breathing apparatus. The system may include an integrated surgical headlight and/or integrated surgical loupes. The system may further offer a face shield that fits very close to the wearer's eyes above the nasal dorsum, allowing use of the system while operating a microscope or the optics of a robotic surgery system.

Claims

1. A respiratory protection system for surgery comprising: a sealable face shield; an air supply; an intake hose with a first end connected to the face shield and a second end connected to the air supply; one or more exhalation ports capable of conveying air exhaled by a user out of the system; one or more filters to filter the exhaled air prior to discharge; and one or more surgical accessories, where the one or more surgical accessories comprise: an integrated surgical headlight; and/or one or more integrated surgical loupes; where the one or more exhalation ports are hoses, that discharge rearward of the system, where the one or more exhalation ports each comprise a terminal end defined by an orifice, such that when the face shield is worn by the user, the orifice is above the head of the user and discharged air is blown behind and above the head of the user rather than into a sterile field in front of the user.

2. The respiratory protection system of claim 1 where the air supply is a powered fan and battery, where the powered fan and the battery are capable of being mounted on a belt.

3. The respiratory protection system of claim 1 where the intake hose is equipped with a filter such that an ambient air may be pulled by a fan into the intake hose where it is filtered prior to entering the face shield.

4. The respiratory protection system of claim 3 where the filter is a HEPA filter.

5. The respiratory protection system of claim 1 where the one or more surgical accessories are removably attached to the hose atop the face shield.

6. The respiratory protection system of claim 1 where the face shield comes down to the user's nasal dorsum such that the system is capable of allowing the user to wear the face shield while operating a microscope or optics of a robotic surgical system.

DETAILED DESCRIPTION OF THE INVENTION

(5) The devices and methods discussed herein are merely illustrative of specific manners in which to make and use this invention and are not to be interpreted as limiting in scope.

(6) While the devices and methods have been described with a certain degree of particularity, it is to be noted that many modifications may be made in the details of the construction and the arrangement of the devices and components without departing from the spirit and scope of this disclosure. It is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of exemplification.

(7) In general, in a first aspect, the invention relates to a respiratory protection system 1. The system 1 may comprise a powered air purifying respirator (PAPR), supplied air respirator (continuous flow respirator), or other self-contained breathing apparatus 2. The system may further comprise one or more integrated surgical accessories 3, which may include an integrated surgical headlight, as shown, and/or integrated surgical loupes.

(8) The PAPR 2 may include a sealable face shield 4 and an intake hose 5 connected on one end to the face shield 4 and on the other to an air supply, such as a powered fan and battery, which may be mounted on a belt. The hose 5 may be equipped with a filter, such as a HEPA filter, such that ambient air may be pulled by the fan into the hose 5 where it is filtered prior to entering the face shield 4.

(9) The integrated surgical accessories 3 may clip or snap onto the intake hose 5 at the top of the face shield 4, as shown in FIG. 2. The system 1 may further comprise one or more exhalation ports 6. The exhalation ports 6 may be capable of conveying air exhaled by the user out of the system. The exhalation ports 6 may be equipped with filters, such as HEPA filters, to filter the exhaled air prior to discharge. The exhalation ports 6 may be hoses that discharge behind the user's head, thus keeping the discharged air from blowing into a sterile field.

(10) Additionally or alternately, the face shield 4 may come down to the nasal dorsum very close to the user's eyes. This may allow the user to operate a microscope or the optics of a robotic surgical system while wearing the face shield. During such use, additional light may not be needed, and thus the surgical headlight may be omitted.

(11) By providing HEPA filtration on both the inhalation and exhalation side of the PAPR 2, the system 1 may protect both the wearer from inhaling aerosols exhaled by others in the vicinity and the others from inhaling aerosols exhaled by the wearer. The sealable face shield 4 may further protect the wearer from infection through the wearer's eyes.

(12) Whereas, the devices and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
