Description
- This is a continuation-in-part patent application claiming the benefit of pending U.S. patent application Ser. No. 10/644,111, filed in the United States Patent and Trademark Office on Aug. 20, 2003.
- 1. Field of the Invention
- The claimed invention generally relates to stethoscopes. More specifically, the claimed invention relates to cordless or wireless stethoscopes.
- 2. Description of the Prior Art
- The threat of rapidly spreading infectious diseases to many different places around the world with little or no notice has significantly increased as international air travel has become commonplace. This threat coupled with increased concerns about possible biological and chemical attacks have resulted in a general increase in the awareness and preparedness of medical personnel to combat these types of threats. Doctors, nurses and emergency medical technicians typically use hazardous material protection suits, commonly known as HAZMAT suits, to protect themselves against these threats. HAZMAT suits completely isolate the healthcare workers from the surrounding environment forming a protective barrier against biological and chemical agents that may be presented by patients being cared for by the healthcare workers.
- It has come to my attention during preparedness training for dealing with these threats that it is impossible for medical personnel to use a standard stethoscope when wearing a HAZMAT suit without compromising the integrity of the suit. Breaking the protective barrier of the HAZMAT suit defeats the purpose of wearing the suit and places medical personnel at risk. There are devices in the prior art that convey auscultatory information gathered by a stethoscope head in ways other than a standard stethoscope, but it has come to my attention that the prior art does not provide a stethoscope device compatible with hazardous material environments.
- U.S. Pat. No. 6,340,350 issued to Simms discloses an electronic stethoscope and holder comprising a chest piece, an earpiece, and a casing for holding the chest piece and earpiece. The chest piece has a radio wave transmitter for transmitting auscultatory sounds from the chest piece to a receiver in the earpiece. This device could be used to transmit auscultatory sounds from the chest piece through a HAZMAT suit to a receiver within an earpiece worn by the suit wearer. However, this device does not address important concerns that are particular to hazardous material environments such as providing a device that is water tight so that it may be easily decontaminated after use in a hazardous material environment or providing a stethoscope head that is easily used while wearing gloves commonly employed by HAZMAT suits.
- U.S. Pat. No. 6,544,198 issued to Chong et al. discloses a stethoscope system for self-examination whereby the condition of health of a particular individual can be diagnosed by comparing characteristic sound waves classified by diseases with sound waves generated from various parts of the individual's body. This device could also be used to transmit auscultatory sounds through a HAZMAT suit. However, this system does not provide a self contained and portable stethoscope device that can be used without other support structures in place and does not address the previously mentioned shortcomings that are particular in a hazardous material environment.
- Therefore, there is a need for a stethoscope device designed for use by medical personnel wearing HAZMAT suits in hazardous material environments.
- To accomplish the goal of providing a stethoscope device for use in hazardous material environments by personnel wear HAZMAT suits, the claimed invention provides a Cordless Stethoscope for Hazardous Material Environments.
- An objective of the claimed invention is to provide a Cordless Stethoscope for Hazardous Material Environments that can cordlessly transmit information from a stethoscope head to a receiver within a hazardous material protection suit.
- Another objective of the claimed invention is to provide a Cordless Stethoscope for Hazardous Material Environments having a fluid tight housing holding the stethoscope head and transmitter to allow easy decontamination of the stethoscope head.
- A further objective of the claimed invention is to provide a Cordless Stethoscope for Hazardous Material Environments having a housing holding the stethoscope head that is designed to be held by a gloved hand.
- An even further objective of the claimed invention is to provide a Cordless Stethoscope for Hazardous Material Environments having a microphone for picking up verbal communications that may not otherwise be audible through a hazardous material protection suit.
- To achieve these objectives, as well as others that become apparent after reading this specification and viewing the appended drawings, the claimed invention provides a Cordless Stethoscope for Hazardous Material Environments.
- The cordless stethoscope generally comprises a sound sensing device having a stethoscope head and a microphone for sensing and transmitting sounds from a patient, a receiver for receiving the transmissions, and earpieces for converting the received transmissions into audible sound for assessment by the person using the cordless stethoscope.
- The sound sensing device comprises a fluid tight housing, a power source, a stethoscope head, a momentary activation switch, a microphone, a microphone activation switch and a transmitter. The sound sensing device is designed to be completely fluid tight so that the device may be decontaminated after use in a hazardous material environment without damaging the inner components of the device. The overall size and shape of the housing allows a user wearing gloves to compensate for the loss of fine motor skills.
- The receiver generally comprises a receiver housing, a receiver, a receiver power source, an earpiece jack and a receiver volume control. Several different types of transmitters and receivers may be used in the cordless stethoscope, with magnetic induction or radio frequency transmission and reception being the preferred transmission means.
- The cordless stethoscope for hazardous material is used by placing the earpieces within the ears of the user and the receiver within a pocket or clipped onto a belt within the HAZMAT suit worn by the user. The sound sensing device is used by placing the activated device adjacent a patient's body to gather auscultatory information that is transmitted via the transmitter to the receiver where the signal is converted into audible sound by the earpiece for assessment by the user of the cordless stethoscope.

Theindicator light 210 indicates power flow to thestethoscope head 30 when themomentary activation switch 100 is actuated. - The
momentary activation switch 100 shown inFIGS. 2, 3 and 5 is situated within theactivation switch opening 170 and is connected in circuit to thestethoscope head 30. The lowfrequency response microphone 260 of thestethoscope head 30 is activated when themomentary activation switch 100 is actuated. A second fluidtight cover 270 is placed over themomentary activation 100 to seal theactivation switch opening 170. - The
microphone 40 is an optional feature of thesound sensing device 20 as shown inFIG. 5 . Themicrophone 40 is used for sensing other communications that may not otherwise be heard by a person wearing a HAZMAT suit. A second fluidtight member 280 between themicrophone 40 and the microphone opening 180 maintains the fluid tight integrity of thehousing 70. Themicrophone activation switch 110 is connected in circuit to themicrophone 40 for activating themicrophone 40. A third fluidtight cover 290 over the microphone switch seals the microphone switch opening 190. - The
transmitter 120 shown inFIGS. 3 and 5 is located within the fluidtight housing 70 and is connected in circuit to thepower source 80 for transmitting the first signal and second signal to thereceiver 50. Thesound sensing device 20 may use several different types of transmitters to effectuate the intended purpose of thecordless stethoscope 10.

receiver 50 shown inFIGS. 6-8 generally comprises a receiver housing 300, areceiver module 310, areceiver power source 320, anearpiece jack 340 and areceiver volume control 350. Thereceiver module 310 may use several different types of receiver to effectuate the intended purpose of thecordless stethoscope 10. Preferably, thereceiver module 310 uses a radio frequency receiver for receiving the signals transmitted by theradio frequency transmitter 120. - Excellent results have been obtained utilizing a low power wireless data transmitter data transmitter (i.e. a wireless data transceiver module) that generally operates in the 2.4 GHz range or more specifically in the 2,400 to 2,485 MHz range. One such device or module is manufactured by Tecnova with current business address of 1486 St. Paul Avenue, Gurnee, Ill., 60031 and sold under the brand name Z
IG RAY , which module requires only a 3.0 volt power source. Transceivers operating in the 2.4 GHz range do not typically interfere with other peripheral hospital medical devices, and thus is one example of a preferred type of transceiver module. - The earpieces 60 convert the signal transmissions transmitted by the
transmitter 120 and received by thereceiver module 310 into first and second analog signal that are converted into audible sound for the person using thecordless stethoscope 10 to hear the auscultatory sound and sound communication gathered by thesound sensing device 20.
