Description
While you'll not find doctor kits in a typical Montessori classroom outside of a guest presentation, this type of imaginative play is encouraged in Montessori. Acoustic stethoscopes operate on the transmission of sound from the chest piece, via air-filled hollow tubes, to the listener's ears. The chestpiece usually consists of two sides that can be placed against the patient for sensing sound: a diaphragm (plastic disc) or bell (hollow cup). If the diaphragm is placed on the patient, body sounds vibrate the diaphragm, creating acoustic pressure waves which travel up the tubing to the listener's ears. If the bell is placed on the patient, the vibrations of the skin directly produce acoustic pressure waves traveling up to the listener's ears. The bell transmits low frequency sounds, while the diaphragm transmits higher frequency sounds. To deliver the acoustic energy primarily to either the bell or diaphragm, the tube connecting into the chamber between bell and diaphragm is open on only one side and can rotate. The opening is visible when connected into the bell. Rotating the tube 180 degrees in the head connects it to the diaphragm. This two-sided stethoscope was invented by Rappaport and Sprague in the early part of the 20th century.

How to Choose a Toy Doctor Kit Additionally, longer tubing gives you better access (especially since some animals don’t want you right in their space), and a double lumen for better sound quality, since vets work in noisier and more varied environments,” she says.

There are three main parts to a stethoscope: the earpieces (rubber tips that go in your ears), the tubing (which carries the sound), and the chest piece (the metal part, or head, of the stethoscope).
Given the unique nature of the patients that veterinarians care for, there are some very specific qualities that will make for a great veterinary stethoscope. It reminds me a bit of the faux medical station at our local children's museum. The kids go right to it every time we visit.

This stethoscope bundle has a durable, waterproof carrying case that keeps the product secure. This may be a good option for someone who is looking for a stethoscope they can bring while traveling. In a study conducted by 3M, the maker of the Littman stethoscope, the company found that patient heart sounds were four times louder through the diaphragm of a Littmann stethoscope than that of the competitor. Which stethoscope is best for vets? The medical historian Jacalyn Duffin has argued that the invention of the stethoscope marked a major step in the redefinition of disease from being a bundle of symptoms, to the current sense of a disease as a problem with an anatomical system even if there are no observable symptoms. This re-conceptualization occurred in part, Duffin argues, because prior to stethoscopes, there were no non-lethal instruments for exploring internal anatomy.

Under normal conditions, it is not necessary to remove the CORE Digital Attachment from the stethoscope during the cleaning procedure.

To tune the diaphragm to different frequencies, a person just needs to adjust the pressure on the non-chill chest piece and rotate the flexible stem to use one of the sides. The smaller surface area is better for lower frequencies. The larger one is better for higher frequencies. A low cost yet reportedly versatile option, this stethoscope features a dual-head diaphragm that can catch high and low frequencies. This may be especially beneficial for people who wish to use this product on adults and children. tunable diaphragm easy to clean, open bell, no latex or phthalate plasticizers, comes in several colors
