Description

Wireless transmission type Bluetooth stethoscope and use method

Technical Field

The invention relates to the technical field of stethoscopes, in particular to a wireless transmission type Bluetooth stethoscope and a using method thereof.

Background

Stethoscopes are the most commonly used diagnostic tools by clinicians. Since 1817 years clinical application, the stethoscope has been improved in appearance and sound transmission mode, but its basic structure is not changed much, and the stethoscope mainly comprises a sound pickup part (chest piece), a transmission part (rubber tube) and a listening part (ear piece). However, the structure has the following problems in the use process:

(1) the length of the rubber tube is difficult to meet the requirement: too long a hose may cause excessive loss of sound during conduction, and too short a hose may cause a physician to need to get closer to a patient during use, which is inconvenient to operate and is easy to increase infection risk. When the rubber tube rubs with foreign objects (such as clothes), the auscultation effect is easily disturbed.

(2) Most of the ear pieces are designed in a hollow metal and rubber earmuff mode, and on one hand, the wearing comfort is poor, and the ear pieces are not suitable for long-time use. On the other hand, when a doctor wears the totally-enclosed isolation suit, the head cover of the isolation suit is externally connected with a stethoscope, so that the isolation suit is difficult to play a role.

(3) After the chest piece and the ear piece are connected by the rubber tube, the stethoscope has poor flexibility when in use, and the objects are too large, so that the stethoscope is inconvenient for doctors to carry.

(4) In the case that a doctor cannot arrive at the site, a patient or a family member with potential cardiopulmonary diseases cannot acquire heart sound and respiratory sound, and an effective means for self-help auscultation and remote auscultation is lacked.
