- the apparatus is fitted to a patient in the following manner:
- the patient's normal bite is inspected by the doctor.
- the doctor then asks the patient to swallow as that tends to align the lower jaw.
- the doctor then asks the patient to move the lower jaw or mandible slightly forward of the normal bite. This may be 2 to 6 millimeters and is determined by the doctor.
- the patient is then asked to practice biting down several times with the jaw advanced in this forward position. When the mandible is moved slightly forward the tongue reflex is to move forward. This in turn helps keep the airway in a more open position.
- a cup of water is brought to a boil in a microwave or water heater and then removed from heat.
- the oral mouthpiece portion of the device is placed in the cup of hot water for 3 minutes.
- the oral device is then removed from the hot water and allowed to air cool for 25 seconds. This prevents burning the patient.
- the oral device is then fitted to the upper teeth.
- the patient is then asked to bite down on the ramp with the jaw in a slightly forward position as practiced.
- the device is removed after approximately 30 seconds and placed in cool water. Any excess material from the impression is cut away and polished with an acrylic burr.
- the mouthpiece When the patient is ready to receive ventilated air the mouthpiece is re-inserted into the patient's mouth as shown in FIG. 2 .
- the tie end is inserted through the quick release lever on the mask.
- the tie end is pulled snugly to ensure a tight mask seal as shown in FIG. 3 .
- the threaded portion of the bushing passes through a hole in the mask portion and the knob is screwed onto the bushing. This allows the knob and bushing to be turned from outside the mask. When the bushing is turned it moves along the anchored screw. This causes the mask to move away from of toward the patients face. The bushing is inserted through the mask opening and the adjustment knob is locked in place.
- the adjustment knob is tightened until the mask is snugly fitted to the patient.
- the ventilator unit is energized and airflow calibrated and set per manufacturers instructions. That completes the basic fitting process of the device.
- the patient then has a preferred system that helps insure that the airway remains open. This reduces the unnecessary alarms that are activated when too little air reaches the patients lungs. This help free up the medical staff for other duties.
- the device can be removed and washed in warm soap and water and or placed in a denture cleaning solution such as Polident for maintaining it clean and fresh. When not in use it should be cleaned, dried and stored for later use.

Anadditional locking channel 110 is thereafter secured to the end of the first conventional releasable cable tie that was inserted into thebores releasable cable tie 108 that was inserted into thebores wood channels 110. Other embodiments will include a bulbous end 38 a and a single slip lock or lockingchannel 110. The view ofFIG. 10 show the pawl engagement with and enlarged view of axial section of cable tie. - The upper portion of one form of the oral device in accordance with the present invention defines a trough for receiving some of the upper teeth. Once inserted into the mouth the device snugly engages the upper teeth, particularly the front teeth, and remains positioned independent of natural motions of the lower jaw. This trough forms a practical anchor point for attachment of a face mask for receiving ventilation of breathing air by means of a ventilator machine and tube.
- Some embodiments of the invention include a lower portion that defines a ramp structure whereby natural jaw motion results in the engagement of the lower teeth with the ramp, which will cam the lower jaw into a more forward position. This action acts to help keep the airway open, thereby, allowing the attached ventilator mask to operate more effectively.
- An adjustable fastener system similar to that described above connects the mask to the oral device. The adjustment feature allows the mask to be moved closer or further from the face until the mask seal is in the ideal position as desired. This feature allows the mask portion to be fitted to the patient without the need for straps or other uncomfortable headgear.
- Most embodiments of the present invention utilize a mouthpiece of the general type that is referred to in the dental industry as a “boil and bite” oral appliance. Such devices include, but are not limited to, anti-snoring medical oral appliances as described in U.S. Pat. Nos. 5,092,346 and 5,277,202. The disclosures therein are incorporated by reference.
- Such oral or anti-snoring appliances are also referred to as mandible repositioning devices and act to keep the airway open during sleep. The appliance is heated and custom molded directly to the patients teeth. The upper trough of the appliance forms a very stable anchor point that holds it securely in place. This stable anchor feature not only holds the mouthpiece in place but becomes the central anchor point for holding the mask against the patients nose and mouth. With the flip of the tongue, or pulling down on the mouthpiece it can be instantly released by the patient or hospital staff.
- The substantial improvements include an adjustable connection method between the mask and mouthpiece. The adjustable connection allows for external adjustment of the tightness of the mask against the patient's mouth and face by using the mouthpiece as an anchor point. In other words, the adjustment feature allows the mask to be moved closer or further from the face until the ideal position is desired. This not only helps keep the airway open but also eliminates the need for bulky and uncomfortable headgear.
- This invention consists of three primary parts that are connected to a ventilation machine by others. The ventilation machine provides the proper amount of breathing air supply and control. It contains necessary alarms and tubing.
- The invention components include the mouthpiece, adjustment assembly and face mask. These may be factory provided in one single assembled unit or provided as a kit so it can be simply connected to most of the conventional face masks available on the market. In this latter case, the straps and headgear would be removed. Existing masks come in numerous sizes, shapes, and a variety of types. Most have straps and headgear in common. Thus, it is clear that other masks can be utilized with the present invention.
- Mouthpiece: The mouthpiece is sometimes referred to as a, “boil and bite” oral appliance in the dental industry.
- Adjustment assembly: The adjustment assembly includes all components necessary for connecting the mouthpiece to the full face mask. The preferred adjustment components may include an extension from the mouthpiece, in the form of a releasable type, nylon cable tie fastener. Representative prior art includes fasteners manufactured by 3M Company, 3M Center, St. Paul, Minn. 55144-1000.
- The fastener in accordance with the present invention includes an elongated member, a ratchet releasable lock and a quick release lever of the type known in the art. This fastener is secured to the mask whereby the tie is tightened by simply pulling on the end of the tie. To release, it is only necessary to depress the quick release lever. The tie is flexible and allows for off-sets to occur between the mask and mouthpiece while it keeps the seal of the mask snugly fitted to the patients face. In other certain variations a screw, bushing and adjustment knob may be used to accomplish the adjustment feature.
- The masks used may be of a number of sizes and shapes but the preferred type is considered the full face mask. This is usually a clear plastic mask that covers the nose and mouth and has a tube for connection to a ventilator. The mask usually contains a soft sealing portion that fits snugly against the patient's face. Some masks have an air filled chamber seal that easily deforms to the patients' face to obtain a tight fit. The prior art apparatus requires the nurse or respiratory therapist to hold the mask in place with several straps along with other complicated headgearas shown in
FIG. 4 . These cumbersome straps and headgear are not used with this invention. - Referring now to
FIGS. 1 , 2, and 3 there is shown amouthpiece mask 10 that includes amouthpiece 20. Themouthpiece 20 in the preferred embodiment is made with a polycarbonate shell such as that sold by General Electric and identified by the trademark Lexan. The ventilation apparatus is fitted directly to thepatient 60 without the need for any laboratory work or molds for teeth impressions. Themouthpiece 20 may, in one form of the invention, have an integral connection port or fastening method for receiving the adjustment assembly that includes acable tie 37 with locking ridges and a free end and a Quickrelease lever lock 38. The end of thetie 37 remote from the free end has a smooth shaped head or bulbous end 38 a that is larger than theopening 25 in the mouthpiece to prevent it from being pulled through the mouthpiece. The entire cable tie is made of nylon. The quickrelease lever lock 38 includes a release lever that allows the free end of the cable tie to be moved when release lever is depressed. The quickrelease lever lock 38 has a short tab that allows it to be riveted or fastened to the mask. The quickrelease lever lock 38 is positioned in line with a hole 44 in the mask to allow thecable tie 37 end to pass through the mask and through the quickrelease lever lock 38. The quickrelease lever lock 38 allows the free end ofcable tie 37 to pass through and thus allow for exterior adjustment to be made for tightening or loosening the mask with respect to the mouthpiece. The fastener also includes a slip onlock 39 for securing the cable tie to mouthpiece. Thislock 39 is made of nylon and has an opening to allow the tie to slip through but prevents the tie from moving back in the opposite direction. Thisslip lock 39 may include a release lever for removal. - The
mouthpiece 20 is designed to custom fit onepatient 60 and is durable and long lasting. Once custom fit for onepatient 60 it cannot be used for any other patient. It may be discarded when the patient 60 no longer uses theventilator 52 andmask 40. Once thepatient 60 is custom fitted with themouthpiece 20 it only takes a few seconds for the patient 60 or medical staff to place it in the patient'smouth 61 for use. - The geometric relationships between the patient and the apparatus are best seen in
FIG. 3 which illustrates the head and face of apatient 60,palate 66,tongue 65, oralanti snoring device 20, mouth ofpatient 61, mask assembly, clearplastic mask assembly 40, quick lockrelease lever lock 38, cable tie with locking ridges and afree end 37,upper teeth 62lower teeth 63,lower jaw 64,tongue 65,palate 66,uvula 67,trachea 68 andesophagus 69. - The mouthpiece mask includes an
adjustment assembly 37. Theadjustment assembly 37 is preferably made of Nylon or another FDA approved material for medical use. The adjustable fastener may includes a releasablenylon cable tie 37 secured by anattachment 39 to themouthpiece 20 as best seen inFIG. 1 . Releasable cable ties are manufactured and sold by a number of business entities. The opposite end of thetie 37 extends through aquick release lever 38 that is bonded to themask 40. This type adjustment is simple to use, easy to manufacture, inexpensive, easy to clean and can be rapidly adjusted and released. - The
attachment 39 may be achieved by bonding, welding, snap-on connection, a clamp, a screw, or other means secured to themouthpiece 20. Likewise thequick connect lever 38 portion may be bonded, screwed or otherwise secured to themask 40. - Referring now to
FIG. 5 there are shown an alternate embodiment of the adjustment assembly in which ascrew 30 portion may have a slottedhead 31 for secure attachment to themouthpiece 20 as best shown inFIG. 5 . Themouthpiece 20 may have a threaded opening located between theupper trough 22 and thelower ramp 23. The threadedscrew 30 is secured to themouthpiece 20. Theshoulder 35 of threadedbushing 33 protrudes though an opening in themask 40. Aknob 36 outside themask 40 is securely fastened to thebushing 33. By turning theknob 36 close-wise, thescrew 33 travels inside thebushing threads 34 and causes themask 40 andmouthpiece 20 to come closer together. Theknob 36 is tightened until acomfortable mask 40 fit andseal 41 is realized. When theknob 36 is turned counter-clock-wise themask 40 andmouthpiece 20 move further apart. - In another form of the invention a semi-flexible section is placed in line with the adjustment fastener. This would allow for an offset to occur thereby, allowing the mouthpiece to fit securely without undue stress of strain that could act to dislodge the upper trough of the mouthpiece from the upper teeth.
- The
mask 40 as shown inFIG. 1 is of a full face type that covers the nose and mouth. This type allows for breathing to occur through the nose and/or mouth. Themouth 61 may also be “open” or “closed”. Themask 40 has a 15 to 22 mm connection port for attachment to an air tube 50, for breathingair 51, and aventilator machine 52. Various attachment may be provided with themask 40 and include ports or connections for supplemental oxygen, other gases, mixtures or vapors. In certain variations or for certain patients 60 a safety strap or straps may be necessary to hold the mask and attachments in place. - In accordance with present invention the apparatus is fitted to a patient in the following manner:
- 1. The patient's normal bite is inspected by the doctor. The doctor then asks the patient to swallow as that tends to align the lower jaw. The doctor then asks the patient to move the lower jaw or mandible slightly forward of the normal bite. This may be 2 to 6 millimeters and is determined by the doctor. The patient is then asked to practice biting down several times with the jaw advanced in this forward position. When the mandible is moved slightly forward the tongue reflex is to move forward. This in turn helps keep the airway in a more open position.
- 2. A cup of water is brought to a boil in a microwave or water heater and then removed from heat. The oral mouthpiece portion of the device is placed in the cup of hot water for 3 minutes. The oral device is then removed from the hot water and allowed to air cool for 25 seconds. This prevents burning the patient.
- 3. The oral device is then fitted to the upper teeth. The patient is then asked to bite down on the ramp with the jaw in a slightly forward position as practiced. The device is removed after approximately 30 seconds and placed in cool water. Any excess material from the impression is cut away and polished with an acrylic burr.
- 4. When the patient is ready to receive ventilated air the mouthpiece is re-inserted into the patient's mouth as shown in
FIG. 2 . The tie end is inserted through the quick release lever on the mask. - 5. The tie end is pulled snugly to ensure a tight mask seal as shown in
FIG. 3 . - 6. In another variation of the invention where a screw type adjustment is used as shown in
FIG. 5 , the screw end with bushing is facing away from the patient mouth. - 7. The threaded portion of the bushing passes through a hole in the mask portion and the knob is screwed onto the bushing. This allows the knob and bushing to be turned from outside the mask. When the bushing is turned it moves along the anchored screw. This causes the mask to move away from of toward the patients face. The bushing is inserted through the mask opening and the adjustment knob is locked in place.
- 8. The adjustment knob is tightened until the mask is snugly fitted to the patient.
- 9. The air tubing from the ventilator is then connected to the mask tube connector fitting.
- 10. The ventilator unit is energized and airflow calibrated and set per manufacturers instructions. That completes the basic fitting process of the device.
- Once fitted with this invention the patient then has a preferred system that helps insure that the airway remains open. This reduces the unnecessary alarms that are activated when too little air reaches the patients lungs. This help free up the medical staff for other duties.
- Each day the device can be removed and washed in warm soap and water and or placed in a denture cleaning solution such as Polident for maintaining it clean and fresh. When not in use it should be cleaned, dried and stored for later use.
- Other forms of the present invention utilize an engagement member, trough or tray for engaging either the upper teeth or the lower teeth of the user. Ordinarily, the upper teeth are preferred because there is less movement. The entire trough for the upper (or lower) teeth is made with a heat formable plastic or polymer. This type tray is, manufactured in a preformed shape so that one size can be used to fit most patients. It is made from a clear polymer and is molded by heating it in warm water and then placing it in the mouth to form a snug mold directly to the upper teeth. The heated plastic will stretch and or shrink during the molding process to provide a snug fit.
