Description

Novel nursing teaching is with double stethoscope

Technical Field

The utility model belongs to the technical field of teaching appliances, and mainly relates to a novel double stethoscope for nursing and teaching.

Background

As a diagnostic means, a stethoscope is used to amplify body-originated sounds emitted from the heart, lungs, stomach, etc. of a human or an animal, and is mainly composed of a sound pickup portion (chest piece), a conduction portion (hose), and a listening portion (ear piece). Using a stethoscope, listeners can hear normal and abnormal respiratory, cardiac, pleural, arterial, venous, uterine, fetal and intestinal sounds. Blood pressure monitoring is an important responsibility of clinical nurses to help determine the abnormal degree of blood pressure, judge the change of illness state, observe the effect of medication, and the like. Proper blood pressure measurement is a care skill that the nurse must master. The beginners are most confused about the judgment of the auscultation sounds of systolic pressure and diastolic pressure, and many beginners cannot master the auscultation of the pulsating sounds of the arteries. Because the stethoscope in the prior art is used by a single person, in the existing teaching, a teacher can only describe the contraction sound and the relaxation sound, and how many students can master depends on the comprehensiveness of the students; in the examination of blood pressure measurement, the accuracy of listening judgment cannot be judged. If the teacher judges the accuracy of the student measurement by a repeated measurement method, the measurement error caused by the personal physiological factors of the tested person cannot be eliminated. In addition, the stethoscope head of the stethoscope in the prior art makes the skin feel cool when contacting with the skin, and the measuring comfort is poor.
