Description
Field of the Invention
The present invention relates to an apparatus for holding and restraining a patient's head during medical treatment.
Background of the Invention
In the medical field there exists a need for an improved device for gently and yet firmly holding and restraining a patient's head in one of a number of fixed angular positions during medical treatment.
One example of medical treatment wherein such a head holding and restraining device is required is in the delivery of continuous positive airway pressure to a patient (often an infant) suffering from a respiratory disease. Continuous positive airway pressure is typcially delivered to the patient through a nasal cannula which must be inserted and held within the patient's nose. A head holding and restraining apparatus is required to prevent the infant or other patient from turning his head and partially or fully removing the nasal cannula from his nose.
One requirement of such a head holding and restraining device is that it be adapted to permit a doctor or nurse to move the patient's head, from time-to-time, to one of a number of angular positions.
While there have been attempts to design head holding and restraining apparatus prior to the advent of the present invention, none has proven to be entirely satisfactory or efficient in use.
Accordingly, it is an object of the present invention to provide a head holding and restraining apparatus for gently and yet firmly holding a patient's head in any one of a number of fixed angular positions during medical treatment.
Summary of the Preferred Embodiment
The foregoing and other objects of the present invention have been realized by providing a generally arcuate or U-shaped cradle member mounted for arcuate or angular movement on a base member. An adjustable clamp is provided for locking the cradle member in a desired angular position. The clamp, when loosened, permits the generally arcuate cradle to be rotated to any desired position. When the desired angular position of the cradle has been reached, the clamp is tightened to lock the cradle in such angular position.
A pair of opposed, generally flexible, generally arcuate head restraining plates are mounted within the generally arcuate cradle member on either side thereof by means which permit the upper portions of the generally flexible restraining plates to pivot inwardly, toward one another, to accommodate, conform to and restrain the patient's head in place. Adjustment means are provided for selectively moving the generally flexible head restraining plates toward one another to hold the patient's head.
A suitable padding, such as lamb's wool, for example, lines the interior exposed surfaces of the restraining plates and the cradle to cushion the patient's head.
Other objects and numerous advantages of the head supporting and restraining apparatus of the present invention will be realized from a review of the following detailed description of a preferred embodiment of the apparatus of the present invention.

Detailed Descrtiption of a Preferred Embodiment
Referring now to the drawings, the head supporting and restraining apparatus 10 of the present invention is seen to comprise a generally arcuate or U-shaped cradle member 12 mounted in a generally arcuate groove 14 (FIG. 3) in a generally flat base member 16 by means of a suitable clamping device 18 (FIGS. 1 and 2). Clamping device 18 is secured to base member 16 by standard techinques, such as by a suitable adhesive, screws, etc. The cradle 12 may be rotated in the groove 14 to any one of a number of desired angular positions. A rotatable locking lever 20 forms part of the clamping device 18 and is provided so that the cradle 12 may be locked in any one of a number of desired angular positions rotation of locking lever 20 in the clockwise direction, for example, applying a clamping force to that portion of clamping device 18 which contacts cradle 12 whereby cradle 12 in turn is locked in a desired angular position, rotation of locking lever 20 in the counterclockwise direction removing the clamping force and allowing cradle 12 to be moved to a different angular position.
In FIG. 1, the head supporting and restraining apparatus 10 of the present invention is shown in conjunction with a continuous positive airway pressure delivery device 22 which is also mounted on the base member 16. However, it is contemplated that the head supporting and restraining apparatus 10 of the present invention may be used alone or with other types of medical devices.
A pair of generally arcuate head restraining plates 24, 24 are pivotably mounted to the interior surface of the cradle 12 by means of a pair of rivets 26, 26 which fit through slots 28, 28 in the lower edge of each of the restraining plates 24, 24.
In the preferred embodiment of the head supporting and restraining apparatus of the present invention the restraining plates 24, 24 are preferably constructed of a suitable flexible material, such as plastic, for example.
As best shown in FIG. 3, a screw member 30 extends through a threaded hole 32 on either side of the cradle member 12, Each screw 30 may be rotated, by means of a knob 34 on the end thereof, so as to move the generally flexible head restraining plates 24, 24 toward one another. Since the head restraining plates 24, 24 are constructed of a flexible material, such as plastic, the plates will return to their initial position (e.g., as shown in FIG. 2) lying against the interior surface of the cradle 12 (as shown in phantom lines in FIG. 3) when the screws 30, 30 are rotated so as to move radially outwardly of the cradle member 12.
A generally arcuate strip of a suitable padding material 38 lines the interior exposed surfaces of the restraining plates 24, 24 and the cradle 12 for cushioning the patient's head (not shown). One convenient way to removably secure the padding 38 in place is to provide mating velcro strips 40, 42 on the interior surface of each restraining plate 24 and the exterior surface of the padding 38, respectively.
In use, the head supporting and restraining apparatus 10 of the present invention is placed on a bed or table on which the patient whose head is to be supported and restrained will be laid. The patient is then laid on the bed with his head resting on the padding 38 which lines the interior, exposed surfaces of the restraining plates 24, 24 and the bottom exposed interior surface of the cradle 12. The screws 30, 30 are then turned in their respective internally threaded holes 32, 32 to move the padding-lined restraining plates 24, 24 toward one another, as best shown in FIG. 3, until the patient's head is gently, but firmly, supported and restrained.
Thereafter any suitable medical device (such as the nose cannula 46 of a continuous positive airway pressure delivery device 22, for example) may, if desired, be positioned and applied to the patient's head.
If and when it is desired to rotate the patient to any desired angular position, the locking lever 20 of the clamp 18 is loosened and the cradle 12 of the apparatus 10 may be rotated through an arcuate path (as shown by the arrows 48 in FIG. 2) to the angular position desired. The locking lever 20 may then be turned to firmly clamp the cradle 12 in that desired position.
While the head supporting and restraining apparatus of the present invention has been shown in the drawings and described above with respect to one particular preferred embodiment thereof, it is to be understood that numerous variations, modifications and changes may be made to the preferred embodiment shown and described without departing from the spirit and scope of the present invention. Accordingly, it is intended that the scope of this patent be limited only by the scope of the appended claims.
