Description
Technical Field
The invention relates to a medical stethoscope, in particular to a double-diaphragm drum type stethoscope capable of raising sounds and protecting ears.
Background
The stethoscope is a medical diagnostic apparatus with simple structure, low price, convenient carrying and wide application, and plays an important role in clinical diagnosis and disease screening activities. However, the traditional stethoscope [ such as the stethoscope product of "jiangsu fulin medical equipment limited" of the national high and new technology enterprise. Address: zhenjiang city star road 16; telephone: 0511-85891000; su zhen food and drug administration (standard) character 2013 No. 1200067; su shi Yao Jian Ji Production No. 2001-0566; YZB/Su (Zhen) 0067-2013] can not completely meet the requirements of real clinical auscultation. Now briefly described as follows.
First, factor of person to be examined
With the advancement of science and technology and the rapid development of economy, people have less physical activity, and the reserve of heart-lung function tends to decline, in other words, heart sounds, respiratory sounds, vascular sounds and the like gradually weaken.
More physical activity is generated before forty years, and obesity is only a certain phenomenon. For a person with a thin body, the position of the heart apex beat can be seen through the chest wall and the heart sound can be clearly heard. Studies have shown that more than 50% of people currently exceed standard body weight, with approximately 15% of people diagnosed with obesity. The subcutaneous fat of the chest and the abdomen is thickened, so that the heart sound, the breath sound and the bowel sound are relatively far transmitted. In addition, due to the buffering, damping and sound insulation effects of subcutaneous fat, the vibration of the vibrating diaphragm (hereinafter referred to as "touch diaphragm") contacting the human body on the front of the listening block is weakened, and the auscultation work of a doctor is hard. In particular, the intensive physical examination of the institutional community can reduce the efficiency of the doctor's work.
Secondly, the defects of the traditional stethoscope
The stethoscope head of the conventional stethoscope is composed of a listening block (called a listening block because it is made of a metal material, not only thick and heavy, but also has a dome-shaped recess formed in the front surface thereof, which is small and shallow), and a touch membrane provided at the mouth of the front surface (the surface of the listening block that touches the skin of a human body) of the listening block. When the touch diaphragm vibrates, a resonance of the inner cavity of the listening block can be caused, and then weak sound generated by the movement of human organs can be amplified. However, it is difficult for the weak sound generated by the physiological activities of the organs of the human body to cause the thick metal auditory mass to generate obvious resonance so as to further amplify the tiny sound generated by the physiological activities of the organs of the human body.
Secondly, the conventional stethoscope has a heavy listening block, and the stethoscope causes a doctor to feel a sense of falling pain and discomfort when the stethoscope is hung on the external auditory canal of the doctor for a long time.
And (III) the earplug of the traditional stethoscope is spherical, is mostly made of thick hard materials or semi-hard materials, and has no variability in shape. The external auditory meatus of doctors has different thickness, thinness and shape. There are problems of sound leakage and noise interference for doctors with a thick external auditory canal. Not only pain and discomfort can be caused to doctors with thin external auditory canals or less than round and smooth external auditory canals, but also local blood circulation disturbance can be caused. Particularly, when the institution group performs centralized physical examination, the ear discomfort of doctors is obvious. The medical staff hearing can be damaged by using the earplugs for a long time (see healthy road programs which are broadcasted by 4 central televisions 12 months 27 nights 6: 00-6: 40 in 2018: old ears and old backs and hidden dangers after hearing loss).
Thirdly, the stethoscope with patent number 201520367705.7 (publication number CN204765703U, publication date 2015.11.18) is designed for clinical teaching. When listening to the teaching of the example of the instructor, a plurality of students, interns or more advanced doctors can keep the indoor quiet state. But for the centralized physical examination of the organization group, the quiet state of the physical examination environment is difficult to ensure; in particular to noise interference of road construction or unit building construction and traffic and commercial propaganda sound equipment. Therefore, the stethoscope is not very suitable for centralized physical examination in institutional groups. In addition, the stethoscope of the patent is complex in structure and high in cost, and the medical diagnosis cost is increased. Meanwhile, the problem of difficult fault maintenance exists, and the method is not very suitable for non-teaching medical structures.
Fourthly, the patent numbers are: 201620578198.6 (grant bulletin No: CN 206044650U; grant bulletin day: 2017.03.29) are the following: the film sleeve (see lines 1-3 of the paragraph [0017 ]) should be different from the diaphragm of the stethoscope touch body. Although the contact diaphragm is thicker, the cost of the contact diaphragm is approximately equivalent to that of the protective sleeve 3 (film sleeve) and the clamping piece 2, and the contact diaphragm is not directly replaced by one patient for each examination. Secondly, a layer of film sleeve is additionally arranged on the outer surface of the contact diaphragm, and whether the sound conduction has a barrier effect or not is to be further observed and discussed. Thirdly, it is difficult to avoid the other parts of the stethoscope head from absolutely contacting the skin of the patient and the inner surface of the clothes. The applicant has appreciated that after auscultation of a patient, the outer surface of the head is wiped with a disinfectant or alcohol.
