VEN'I UR, APT/4UP 5. /BERALL ATTORNEYS ADJUSTABLE HELMET FACE MASK BACKGROUND OF THE INVENTION This invention relates generally to an adjustable helmet face mask for mounting physiological sensors. In the increasingly complex technology of today, medical personnel find it necessary to have a great number of measurements of the physiological parameters of a patient. These parameters are vital for the accurate prognosis and diagnosis of the patient. In the past many of these measurements were taken manually, for instance the measurements of blood pressure and temperature. Manual measurement of these physiological parameters is inadequate because it is both inconvenient and time consuming to obtain continuous readings of these parameters which are necessary if changes in the patients conditionare to be observed. Also, if each of the required physiological parameters were to be measured manually, it would be most difficult to take there measurements simultaneously as each of the measurements would require an individual to take the measurement.
Recently, devices for receiving electrodes and the like have been developed for placement on a patients head. For example the teaching of Ulett (US. Pat. No. 2,426,958) discloses an electrode holder of rigid construction having a band which may be adjusted about the wearers head and secured by a wing nut and bolt fitting through overlapping portions of the band and slidable in a longitudinal slot provided on one end of the band. These devices are generally expensive, uncomforta ble and inadequate for the purposes of measuring a number of physiological parameters. Consequently, it is desirable to provide a helmet for receiving physiological sensors which will be lightweight, flexible, inexpensive and comfortable for the wearer. It is also desirable to have such a helmet which will be adjustable to any human head.
SUMMARY OF INVENTION In a principal aspect the present invention takes the form of an adjustable helmet face mask for mounting physiological sensors, adapted to fit any persons head, comprising, an anterior portion having a single center, a plurality of flexible arms extending from the center, each of the flexible arms having fastening means for fastening the arms, and means for mounting physiological sensors in sensor locations, and a posterior portion having means for receiving the fastening means such that the helmet face mask is adjustable to a human head, and means for accommodating the physiological sensors in sensor locations.
In a preferred embodiment the plurality of flexible arms of the anterior portion comprise three flexible arms joined to the center of the anterior portion so as to form a substantially inverted Y. The upwardly extending arm is adapted to fit the contour of the wearers forehead from the upper portion of his nose to the back of his head, and the second and third arms are adapted to fit the contour of the wearers face from the FIG. 4 is a top view of the wearer and helmet shown in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1-7 show an adjustable helmet face mask for mounting physiological sensors which employs the principles of the present invention. The device includes an anterior portion 10 having a single center 12 from which extend a first flexible arm 14, a second flexible arm 16 and a third flexible arm 18 joined together so as to form an inverted Y as seen in FIG. 2 and FIG. 6.
The posterior portion 20 shown isolated in the perspective view of FIG. 5 includes a vertical flexible band 22 adapted to fit over the wearers head extending from beneath one ear to beneath the other ear. An upper horizontal flexible band 24 is joined at each end to the vertical flexible band 22 at positions above each of the wearers ears respectively. A lower horizontal flexible band 26 is joined at each end of the lower horizontal flexible band 26 to the ends of the vertical flexible band 22 beneath each of the wearers ears. A vertical segment band 28 joins midpoint 25 of the upper horizontal band 24 to the midpoint 27 of the lower horizontal band 26.
The posterior portion 20 is rendered secure on the wearers head by the vertical flexible band 22 fitting over the wearers head which prevents movement of the mask downwardly and by the upper horizontal flexible band 24 fitting behind the upper part of the wearers head which prevents slippage of the mask toward the wearers face. The lower horizontal flexible upper portion of his nose over his left and right cheekbones respectively, and beneath his left and right ears respectively. The means for accommodating physiological sensors comprises a number of grommets attached to the flexible arms at sensor locations. The means for securing the posterior portion includes at least one flexible band adapted to fit behind the persons head and adapted to receive the fastening means for fastening the arms such that the anterior portion and the posterior portion are held securely on the persons head.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of the profile of the head of a wearer with a first preferred embodiment of the adjustable helmet in place on the head;
FIG. 2 is a front view of the wearer and helmet shown in FIG. 1;
FIG. 3 is a rear view of the wearer and helmet shown in FIG.
The helmet is rendered adjustable to fit any persons head by means of fasteners 30 joined to ends of the vertical flexible band 22 and to the midpoint 25 of the upper horizontal band 24 which are adapted to snap into any of the slots 32 located along the first second and third flexible arms 14, 16, and 18, respectively.
Grommets 34 for receiving physiological sensors are snapped securely into flexible bands 22, 24, and 26 and flexible arms 14, 16 and 18 in a number of sensor locations. For instance, rornmet 34ais located over the ersons tem oral arg P P tery for mounting the physiological sensor for measuring temporal blood pressure and grommet 34 b is positioned near the persons earlobe for mounting the blood oxygenation sensor.
The adjustable helmet is positioned on a person s head,
locating the single center 12 of the anterior portion 10 on the respectively forming the substantially inverted Y shown in FIG. 2. The helmet is locked into position extending the ends of the second and third flexible arms 16 and 18 to positions near the fasteners 30 and snapping the flexible arms 16 and 18 into positions rigid yet comfortable for the wearer.
The adjustable helmet thus fastened is in a secure position on the wearers head, anchored in front at the upper portion of the wearer's nose by anterior portion and in back beneath the wearers external protuberance 29 by the posterior portion 20.
FIG. 7-11 show a second preferred embodiment of an adjustable helmet face mask for mounting physiological sensors which employs the principles of the present invention.
The posterior portion 50 shown isolated in the perspective view of FIG. 10 differs from the embodiment of FIG. 5 is several aspects. The upper and lower horizontal flexible bands 24 and 26 of FIG. 5 are replaced by a singlehorizontal band 52 fitting behind the wearers head beneath his occipital protuberance 29 and having cavities through which the wearers ears may fit. As in the first embodiment shown in FIG. 5, a vertical flexible band 54 fits over the wearers head from beneath one ear to beneath the other. Also, a flexible connecting vertical segment 56 connects the midpoint 53 of the single horizontal band 52 to the midpoint 55 of the vertical flexible band 54.
The anterior portion58 of the second preferred embodiment shown in FIG. 11 differs from that in FIG. 6 only in that the first flexible arm 60 is shorter than the first flexible arm 14 of FIG. 6. The difference is attributable to the fact that the first flexible arm 60 is designed to be secured atop the wearers head to the vertical flexible band 54 as shown in FIG. 7 rather than behind the wearers head to the upper horizontal band as shown in FIG. 1.
A particular example of monitoring apparatus is shown in FIGS. 2 and 12. There a blood pressure transducer 62 is mounted over the wearers temporal artery. A pressure sensitive diaphragm 63 is employed in the transducer to sense the blood pressure of the wearers external temporal artery. The position of the diaphragm will vary with the varying blood pressure of the wearer.
The transducer 62 may take the form of a Wheatstone Bridge 64 having fixed resistors 65, 66, 67 and 68 and a variable resistor 69. The variable resistor may be positioned on the diaphragm 63 so that movement of the diaphragm 63 causes physical distortion of the variable resistor 69. The distortion varies the resistance of resistor 69 and serves to produce a voltage across the output terminals 70 of the bridge 64 representative of the distortion.
Power is supplied to the transducer 62 from a DC voltage source 71. The current from source 71 may be controlled by a single pole, single throw, manually operable switch 72 in series with source 71. The switch 72 and source 71 are in series across input terminals 73 of thebridge 64.
The voltage across the output terminals 70 is transmitted to a voltage amplifier 76 as shown in the block diagram of FIG. 12b. Output voltage is fed through a voltage amplifier 76 to a modulator 78 where it is modulated by a radio frequency carrier wave produced by a radio frequency generator 80 and radio frequency amplifier 82. Power source 84 supplies power to the individual units. The wave shape then flows into antenna 86 where electromagnetic wave shapes are formed and radiated.
The voltage may be monitored on an oscilloscope, voltmeter, or digital recorder after reception by a radio frequency receiver having a dipole antenna 86, filter 88, demodulator 90 and power supply 92 as shown in the block diagram 120. An oscilloscope 94 would be preferable to show time varying changes in the blood pressure wave shape whereas the voltmeter response would merely show an arrow wavering between the systolic and diastolic blood pressure of the wearer.

that all those embodiments obvious to persons skilled in the art, and all those embodiments which are equivalent are to be included within the scope of the claimed invention.
