History of stethoscope


Hii friends… Today I am going to inform you about the (journey) History of stethoscope. Let me explain some parts of the stethoscope.


It all commenced with a paper tube.Modern stethoscopes: 200 years in the making.

In 1816, French health practitioner Rene Laennec invented the first stethoscope .he use of a long, rolled paper tube to funnel the sound from the patient’s chest to his ear. Accounts fluctuate on precisely how Laennec created his invention, however it used to be clear from the establishing that the acoustic homes of the tube radically increased Laennec’s capacity to hear quintessential coronary heart and lung sounds. Laennec coined the title “stethoscope” from two Greek words: stethos (chest) and skopein (to view or see). He additionally referred to as his approach of the use of the stethoscope “auscultation” from “auscultare” (listen).

Twenty-five years later, George P. Camman of New York, developed the first stethoscope with an earpiece for every ear. This layout would be used for extra than a hundred years with very few modifications.

Parts of Stethoscope:

And now we know the history of stethoscope.Parts of stethoscope.Now I am going to explain the types of stethoscope

History of stethoscope
Parts of Stethoscope
  1. Earpieces – 2
  2. Binaurals -2
  3. Tubing – 1
  4. Bell -1
  5. Diaphrugm -1

  1. The rubber or plastic ear pieces It It should fit snugly and comfortable in to the nurse’s ears.
  2. • The binaurals
    It should be angled and strong enough. To ensure the best reception of sound, the earpieces follow the contour of the ear canal pointing towards ear canal when the stethoscope is in the car.
  3. The polyvinyl tubing
    It should be flexible and 30 to 40 cm or 12 to 18 inches in length.

4. • The chest piece.
It consists of bell and diaphragm that are rotated into position. The diaphragm or bell must be in proper position during listening of the heart sounds through the stethoscope. The diaphragm is the circular, flat portion of the chest piece covered with a thin plastic disk. It transmits high pitched sounds created by high velocity movement of air and blood. Bowel, lung and heart sounds are auscultated using the diaphragm. The bell of the chest piece is usually surrounded by a rubber ring. The ring avoids chilling the client, with cold metal when placed on the chest. The bell transmits low pitched sounds cre- ated by the low velocity movement of blood. The car piece should be removed regularly and cleaned of cerumen (car wax) with spirit swab. The bell and diaphragm are cleaned of dust and body oils. Clean the tubing with mild soap and water or alcohol swabs.
Site of Pulse:-
A pulse may be measured in many sites

History of stethoscope
  1. Temporal: Site is superior and lateral to the eye over the temporal lobe.
  2. Carotid: Along medial edge of sterno cleido mastoid muscle of the neck.
  3. Apical: Fourth to fifth intercostal space at left mid claviclular line.
  4. Brachial: Groove between biceps and triceps muscles at the ante-cubital fossa.
  5. Radial: Radial or thumb side of forearm at wrist.
  6. Ulnar: Ulnar side of foream at wrist.
  7. Femoral: Below the inguinal ligament, midway between symphysis pubis, and anterior supe- nor iliac spine.

When did doctors start using stethoscopes?

Facts of stethoscope:-

And now , we know the history of stethoscope.The stethoscope can be used to listen to a variety of sounds to assist with the assessment and diagnosis of a patient.  These include lung, heart and bowel sounds.  The stethoscope is also routinely used in association with a sphygmomanometer to assess blood pressure by listening to blood flow sounds.

When using a stethoscope remember that the ear tips should point forwards in your ears to follow the natural path of your ear canals to ensure best acoustics.  Best practice when using a stethoscope is to use it at skin level and don’t forget to clean it after use to help control the risk of infection.
