Technical Field

The utility model relates to a medical instrument, in particular to a heating and disinfecting device for a stethoscope.

Background

The stethoscope is the most common diagnostic device in hospitals and is the mark of doctors, and modern medicine begins with the invention of the stethoscope. Auscultation is one of the important diagnostic tools for doctors, and is also an important method for the vital sign assessment of patients. The stethoscope has been improved greatly in appearance and sound transmission mode since its clinical application, but its basic structure is not changed much, and it is mainly composed of sound pick-up part (auditory head), conduction part (rubber tube) and auditory part (ear piece).

The stethoscope head in the prior art is mostly made of metal, and during the auscultation process, the stethoscope head needs to be in contact with the skin of a patient. And when the weather is cold, the temperature of the auditory head is lower. This causes the stethoscope to be uncomfortable to the patient when in contact with the patient, and the cold head has a certain effect on the diagnostic result, thereby affecting the working efficiency of the physician.

Meanwhile, the stethoscope is one of the medical instruments which are most widely used and frequently used by medical staff. The stethoscope is contacted with different patients, and pathogenic bacteria on the stethoscope can be transmitted to other patients through contact to cause cross infection. It is statistically estimated that about 20% to 40% of hospital infections are caused by cross-infection, and therefore it is necessary to clean and sterilize the stethoscope to prevent cross-infection.
