Description
Background of the Invention
1. Field of the Invention
The present invention relates generally to an endotracheal tube apparatus and more particularly to an endotracheal tube holder having an improved V-shaped tube securing device whereby the endotracheal tube is held in a positive secured manner within the tube holder after the tube is inserted in the patient's trachea so that the endotracheal tube is fixedly mounted to prevent inadvertent movement after the tube has been properly positioned within the trachea.
2. Description of the Prior Art
Endotracheal tube devices are used under several conditions such as for ventilating a patient during anesthesia, for resuscitation, as well as during critical care not only in the hospital but also during the time when a patient is being transported.
It is well known in the art that various problems and difficulties are being encountered in providing suitable means for securing an endotracheal tube in a simple and positive manner to the tube-holding device which is part of the mouthpiece of the face plate assembly.
Many types of securing arrangements have been tried in the prior art which very often included simply mounting the tube in place with adhesive tape to several areas of the patient's face.
Some endotracheal tubes were mounted in a face plate that included a bite block whereby the patient was required to grip the bite block with his or her teeth. However, other prior art tube holders have included locking means for securing the endotracheal tube to the face plate of the tube holder.
For typical examples of prior art endotracheal tube holders one may refer to those disclosed in the following U.S. Pat. Nos.:

Brief Summary and Objects of the Invention
The present invention defines an endotracheal tube holder formed with a face plate adapted to fit over the patient's mouth area below the nose and just above the chin with the extending longitudinal sides being arranged to cover the patient's lip area.
An adjustable head strap is attached to slotted openings positioned adjacent the outer free edges of the face plate to allow adjustment from either side.
The face plate has an inverted, substantially L-shaped channel having an open end to receive an endotracheal tube which is positioned in an inwardly extended V-shaped portion of the channel.
A mouthpiece that defines a bite block is fixedly mounted to the inner facing side of the face plate. The bite block is also provided with a V-shaped notch to correspond to the V-shaped portion of the channel.
On the outer side of the face plate is a positive tube securing means defined by a tube holding block assembly having a L-shaped channel and V-shaped recess corresponding to the face plate, whereby the endotracheal tube can be first positioned in the patient's mouth and throat prior to mounting the tube holder. After the tube holder is positioned over the endotracheal tube, a suitable thumb screw is mounted to one side of the tube-holding block assembly and is then adjustably engaged with the tube, thereby forcing the tube to become fixedly wedged in a locked position in the "V" portion that is defined by the holding block assembly.
Thus, the present invention has for an important object a provision wherein the face plate of the endotracheal tube holder includes a positive holding means for the endotracheal tube that comprises an integral tube-holding block assembly formed with a tube receiving channel, the closed end of the channel being defined by a V-shaped notch in which the tube is fixedly engaged by means of an adjustable thumb screw. This novel tube-holding block assembly prevents the endotracheal tube from moving in a longitudinal direction and also inhibits rotational movement once the tube is properly positioned in the patient's trachea.
Another object of the present invention is to provide an endotracheal tube holder that will accommodate a number of different sizes of tubes and lock the selected tube firmly in place.
Still another object of the invention is to provide an endotracheal tube holder with an integral bite block having a corresponding V-shaped notch to receive the tube therethrough so that the bite block further aids in the alignment of the tube within the mouth of the patient.
A further object of the present invention is to provide an endotracheal tube holder wherein the face plate includes an aperture which allows additional access to the interior of the patient's mouth without interfering with the position of the endotracheal tube.
Still another object of the present invention is to provide a tube holder of this character that includes an adjustable headband arranged to be adjustably attached to the opposite ends of the face plate by VELCRO.RTM. or other suitable securing material.
A still further object of the invention is to provide a tube holder of this character that is simple in construction and relatively inexpensive to manufacture.
The characteristics and advantages of the invention are further sufficiently referred to in connection with the accompanying drawings, which represent one embodiment.
After considering this example, skilled persons will understand that variations may be made without departing from the principles disclosed; and I contemplate the employment of any structures, arrangements or modes of operation that are properly within the scope of the appended claims.

Detailed Description of the Invention
Referring more particularly to FIG. 1, there is shown the preferred embodiment of the present invention which is defined as an endotracheal tube-holder apparatus, generally indicated at 10, and illustrated as it would be typically worn by a patient 12.
The endotracheal tube-holder apparatus 10 is defined by a face-plate assembly, indicated generally at 14, which is securely mounted to the patient's head 16 by means of an adjustable attaching means 18, and will be hereinafter described in more detail. Face-plate assembly 14 comprises an elongated arcuate face plate 20 made of a suitable thermoplastic material adapted to be positioned over a patient's face so as to directly cover the mouth by means of the adjustable attaching means 18. The material from which the face place member is made should be sufficiently flexible to fit the contour of the patient's face.
Face-plate member 20 is formed with a channel 22 which has a substantially inverted L-shape configuration, the channel having an open end 23 to receive an endotracheal tube 24 and a closed end 26 in which tube 24 is fixedly secured.
The endotracheal tube is generally positioned within the patient's mouth so as to be properly inserted within the trachea. Once the endotracheal tube 24 is properly positioned therein it should not be allowed to move longitudinally or to rotate. This is readily accomplished by mounting face-plate assembly 14 over endotracheal tube 24 by positioning the open end 23 of channel 22 to receive tube 24, whereby the tube 24 is further positioned within closed end 25 of the channel which is formed as a substantially V-shaped notch 26.
To provide a positive securing means for the endotracheal tube there is integrally mounted to the outer surface of face plate 20 a tube-holding block assembly, designated generally at 30, which comprises a holding-block member 32 and preferably made of polyethylene which is integrally molded into face plate 20, as shown in FIGS. 1, 2 and 3.
Holding-block member 32 is provided with a configuration that allows it to be superposed substantially over the perimeter of channel 22 of the face plate. Accordingly, the configuration of holding block member 32 comprises a vertical mounted wall 34, and an integral horizontal wall 35 which extends outwardly to establish a substantially V-shaped securing notch 33 which is defined by a pair of converging wall members 36 and 37 adapted to receive an endotracheal tube 24 of any suitable size, as illustrated in FIGS. 1, 2 and 3.
Vertical wall 34 of the member 32 includes a threaded bore 38 in which is threadably mounted a thumb screw 40, also preferably formed of polyethylene. An additional holding means, indicated at 42, comprising a dualsided adhesive tape 43 is secured to the inner surface of V-shaped notch 33 for engagement with tube 24 before thumb screw 40 is tightened against tube 24. The two-sided adhesive tape not only holds tube 24 in place while thumb screw 40 is tightened but also cooperates to prevent both longitudinal and rotational movement that may be inadvertently applied to the endotracheal tube once it has been correctly positioned in the patient's mouth and trachea.
There is also provided a bite block 45, having a substantially rectangular configuration, integrally mounted to the rear surface of face plate 20. Bite block 45 is made from a suitable firm but somewhat soft plastic material that is comfortably structured and adapted to be positioned within the patient's mouth so that it can be firmly grasped by the teeth without affecting the tube mounted therethrough.
A V-shaped notch 46, which is defined by a pair of converging inclined surfaces, is formed in one side of the bite block so that it aligns with both corresponding V-shaped notches 26 and 33 of the respective channel 22 and the tube-holding block assembly 30.
The adjustable attaching means 18, as heretofore mentioned, comprises a headband that is formed having an intermediate stretchable section defined by an elastic cloth strip 52 that has a limited stretch capability to prevent the patient from readily removing the headband. Each end of intermediate elastic strip 52 has an interlocking strip of material 53, such as VELCRO.RTM. This interlocking strip 53 comprises a first section of hook material 54 and a second section of loop material 56 which are secured to each other.
Each oppositely disposed hook strip 54 is arranged to be inserted through slots 58 formed in face plate 20. Each hook section 54 is looped about its respective slot 58 so as to be adjustably connected to the corresponding loop strip 56.
Accordingly, both ends of the headband can be adjusted whereby the endotracheal tube-holder apparatus can be properly positioned over the patient's mouth, as illustrated in FIG. 1. If desire, the entire headband may be made of a stretchable material having a limited stretch capacity with suitable Velcro.RTM. sections at least one end thereof.
It should be noted that face plate 20 is provided with an access opening 60 which permits various medical instruments to be passed through so as to be inserted into the mouth of the patient, as may be necessary.
The foregoing should only be considered as illustrative of the principles of the invention. Further, since numerous modifications and changes may readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation as shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the claimed invention.
