The excellent acoustic sensitivity o 2047U/C - ULTRASONIC/CONTACT STETHOSCOPEThe 2047U/C combines the features of the 4020 standard stethoscope - with those of an ultrasonic (sounds higher in frequency than the ear can hear) detector. Many watches and clocks generate a considerable amount of ultrasonic energy which will travel a great distance if unobstructed. If the watch or clock can be "seen" by the ultrasonic probe, detection ranges on the order of 1 to 20 feet are not uncommon. The ultrasonic probe is highly directional so it tunes out background noise. The system consists of an amplifier/detector assembly (measures 1x3x5 inches), contact probe, ultrasonic probe, and headset, carrying case. The amplifier/detector is powered by a single 9-volt battery.A 20-foot contact probe extension cable, 20-foot ultrasonic probe extension cable, recorder cable and other accessories are also available by special request.The 2047 is a pocket sized high gain, low noise amplifier which combines a standard electronic stethoscope with those of an ultrasonic detector. The ultrasonic probe is highly directional and tunes out background noise.The 2047U/C also does an excellent job locating video cameras, hidden tape recorders, and video tape recorders.Executive protection agents and bodyguards frequently use the 2047U/C to detect hidden tape recorders, video recorders, cam-corders, and other cameras. This is accomplished by concealing the ultrasonic probe in the sleeve and covertly sweeping a suspect item or person to determine covert eavesdropping devices. The contact probe is then used to further explore potential threats. The 2047U/C is commonly used along with a 2060LV RF detector.The 2047U/C is designed to detect conducted surface vibrations in the audible range as well as airborne sounds in the ultrasonic (above normal hearing) range of 35 to 45 kilohertz (KHz). The unit is supplied with amplifier/detector assembly, contact transducer/ probe (SILVER), ultrasonic transducer (BLUE), special 2,000 ohm headset and carrying case. The unit is designed specifically to be used with the high impedance headset supplied and not low impedance (8-32 ohm) headsets.TO OPERATE AS A STANDARD STETHOSCOPE: Insert the contact probe (SILVER) into the CONTACT PROBE jack. NOTE: There are three (3) jacks of the same physical type on the unit, be careful not to confuse one with the other. Place the YELLOW switch in the CONTACT-DOWN position. Insert the headset into the HEADSET jack. The headset is worn with the gray tube under the chin with the sound output holes facing slightly forward (30 degrees). Place the probe on the desired surface and adjust the VOLUME accordingly.TO OPERATE AS ULTRASONIC STETHOSCOPE: Screw the ultrasonic probe (BLUE) onto the ULTRASONIC PROBE connector. Make sure the connection is firm but not over-tightened. Place the YELLOW switch in the ULTRASONIC-UP position. Point the open end of the probe at a mechanical clock or watch (source of ultrasonic sound) and adjust the VOLUME. Bear in wind that ultrasonic energy will travel considerable distances if unobstructed. A single sheet of paper, for example, will effectively block ultrasonic energy from reaching the probe. The ultrasonic probe can be tested by having someone tear a sheet of paper 20 to 30 feet from the probe. The sound should be heard clearly.The unit has a RECORDER output jack which provides line level audio into 10,000 ohms. This jack is run to the AUX (AUXILIARY) input on a tape recorder.The 2047U/C is powered by a single standard 9 volt battery (Alkaline always preferred) which will provide an approximate total of 70 hours ON time. To replace the battery, loosen the two silver screws on the sides of the unit one or two turns. Carefully lift off the back cover, remove the old battery (noting its position), replace it with a fresh battery and replace the back cover. Be careful not to pinch the battery connector leads with the back cover. Tighten the two screws but don't over-tighten. Remove the battery during prolonged periods of storage. As with any piece of sophisticated electronic equipment, do not store the 2047U/C in extreme heat or humidity.NOTE: Television sets generate frequencies which fall into the detection range of the ultrasonic probe, therefore, do not operate the 2047U/C within 100 feet or an operating TV set, monitor, or computer display. A Beginner's Guide to Using a Stethoscope --------------------------------------------------------------------------------This exercise is intended to teach students how a doctor uses a Stethoscope to diagnose disease. Learning to use a stethoscope takes considerable experience. If anything "abnormal" is heard during this exercise, this should not be taken as a sign of illness. Only a trained doctor can make that determination. Functional stethoscopes can be purchased from medical or nursing supply stores for as little as $10. More expensive models are not necessary for teaching purposes.Stuff needed for this exercise: A stethoscope Balloons 1/2" x 6" diameter plastic tube New disposable sponges Water What is the Stethoscope For? Stethoscopes are used to hear sounds generated from within the body. They are used to listen to the heart, lungs and intestinal tract. They are also used for measuring blood pressure.Basic Terminology Bell The bell of the stethoscope is the cup shaped part at the end of the tubing, usually opposite to the diaphragm. Not all stethoscopes have a bell. The bell is used to listen to low pitch sounds. Diaphragm The diaphragm of the stethoscope is the flat part at the end of the tubing, with the thin plastic "drum-like" covering. The diaphragm is used to listen to high pitch sounds. Some stethoscopes have a diaphragm but no bell. Tubing The stethoscope tubing transmits sound from the bell or diaphragm to the earpieces. Some stethoscopes have single tubes, some have double tubes. Double tubes are more sensitive, but may rub against one another causing "squeaks" to be heard. Earpieces Earpieces fit into the ears. They should angle slightly forward for the best fit. Earpieces made of soft rubber are more comfortable and may prevent outside sounds from interfering with your listening. What Do You Listen For? Heart The heart is located on the left side of the chest, between the 4th and 6th ribs, almost directly under the breast. Use the stethoscope to listen to your heart. Move it around and notice if it sounds any different in different places. Compare the sounds heard using the bell versus the diaphragm.Normal heart sounds are "lub-dub". Each "lub-dub" represents one contraction of the heart. The noises are made when the valves snap shut. "Lub" is the closing of the atrioventricular valves; "dub" is the closing of the pulmonic and aortic valves (look 'em up in an anatomy book!)Some people may have other heart sounds as well. If a quiet "whoosh" is heard after the "lub-dub", this is called a "murmur". Murmurs are the sounds of the blood itself moving through the heart. It makes noise when the blood flow has turbulence. This can be because a valve doesn't open or close all the way. Many people have heart murmurs without it affecting them at all. If someone in the class has a murmur, ask if you can listen and compare to your own heart's sounds.Lungs and Airways Listen to your lungs by placing the stethoscope over your chest and breathing in and out deeply and slowly. Move the stethoscope around and compare the noises heard in different areas. Compare the sounds heard using the bell versus the diaphragm. Normal lung sounds should not have any crackles or wheezes in them. Place the stethoscope over your throat and listen to the sounds your trachea makes.Percussion may be performed on the chest as well. Instead of listening for sounds made by the body, you are listening for sound reflected by sounds you make. For this exercise you need a partner. Place the stethoscope on your partners chest and lightly "thump" a finger against their chest all around the stethoscope. Normal sounding lungs sound slightly "hollow" because they have air in them. Compare this to holding the stethoscope over something solid like a shoulder blade. This sounds "dead". If a lung sounds dead on percussion, it can indicate that the lung has solidified, usually because of pneumonia. Abnormal lung sounds include crackles and wheezes. If the lung rubs on the chest wall there may be friction rubs. Crackles sound just like the word sounds. They indicate that there is fluid in the lungs, such as happens with pneumonia or pulmonary edema. Wheezes are high pitched whistling noises, and are heard with some pneumonias and with airway diseases like bronchitis. Friction rubs are squeaky sounds that can be heard with pleuritis (an infection between the lung and the chest wall). To mimic these sounds, create a model of the lung. Take a balloon and stretch the open end over one end of the tube. Take a sponge and shred it into small pieces. Push the pieces through the tube into the balloon, until the balloon is slightly stretched. Add enough water to moisten the sponge. Squeeze out any excess. Now hold the stethoscope to the balloon and blow in and out on one end of the tube to slightly inflate the balloon. The slight crackly noise you hear is similar to the crackles heard in patients with pneumonia. Wheezes can be simulated by pinching on the neck of the balloon, where it meets the tubing while blowing in and out. Friction rubs can be created by rubbing on the side of the balloon to make it squeak. Abdomen The abdomen can be listened to much like the chest. Holding the stethoscope over the upper left part of the abdomen, just under the ribs, you can hear the stomach gurgling. In the lower part of the abdomen you can hear the intestines. These noises are called "borborygmus". Borborygmus is normal. However, a doctor will listen to these noises and compare them with what is "normal" to decide if your intestinal tract is overactive or underactive. Percussion can also be used to listen to the abdomen. Thumping over the upper right of the abdomen should sound "dead" as a solid organ, the liver, is below it. The stomach or lower abdomen may sound hollow if there is gas in the intestinal tract. Using a stethoscope is an age-old art in medicine and is a very useful, non-invasive diagnostic tool to help localize problems. This is important to allow the doctor to determine what further tests are needed to diagnose disease. |
