Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a paediatrics stethoscope.
Background
A stethoscope is a medical instrument used to listen to sounds in the body, such as: heart, respiration, and intestines and stomach. The stethoscope was created by french doctor lenac in 1816 and published in 1819. The stethoscope is an important method for doctors to examine patients and diagnose diseases. The stethoscope has been improved 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 (chest piece), transmission part (rubber tube) and listening part (ear piece).
The auscultation head of current stethoscope is metal material, and the surface is very cold, especially in cold winter, and the auscultation head is pasted on infant's skin, can let infant very uncomfortable, resists the auscultation and arouses the erroneous judgement, and some stethoscopes directly set up heating device in the inside of auscultation head, though guaranteed the temperature of auscultation head, but influenced the transmission of auscultation head to sound, and then influenced doctor's diagnosis.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a paediatrics stethoscope solves the auscultation head surface ice-cold of current stethoscope, leads to the infant to resist the auscultation and arouses the problem that doctor misdiagnosed.
The utility model provides a basic scheme that: a pediatric stethoscope comprises a stethoscope head, a rubber tube, a three-way tube and a spring piece, wherein one end of the rubber tube is communicated with the stethoscope head, the other end of the rubber tube is communicated with the three-way tube, two ends of the three-way tube, which are far away from the rubber tube, are respectively communicated with an ear tube, the free end of each ear tube is provided with an earplug, and the two ear tubes are connected through the spring piece;
the stethoscope head is characterized in that a heat preservation sleeve is slidably sleeved on the outer side of the rubber tube and made of cotton materials, cartoon plush is arranged on the outer surface of the heat preservation sleeve, the heat preservation sleeve is provided with an inner cavity with an opening facing the stethoscope head, a double zipper is arranged at the opening, an interlayer is arranged in the heat preservation sleeve, a PTC ceramic piece is placed in the interlayer, a power supply box with a storage battery is arranged on the outer side of the heat preservation sleeve, and the storage battery is connected with the PTC ceramic piece through a conducting wire.
Working principle of basic scheme: the storage battery provides electric energy to heat the PTC ceramic piece, the heat makes the pickup surface temperature of the auscultation head approach to the surface temperature of the human body through the interlayer of the thermal sleeve, when a doctor needs to use the stethoscope, the double zippers are unzipped, the thermal sleeve slides to the rubber tube, the pickup surface of the auscultation head is attached to the skin of an infant, and after the auscultation is finished, the stethoscope is usedThe stethoscope head is put into the inner cavity of the thermal sleeve by the sliding thermal sleeve, the double zippers are pulled up, the stethoscope head is waited for the next patient to use, and if the stethoscope head is not used for a long time, the power supply of the storage battery can be stopped.
The basic scheme has the advantages that：
(1) The stethoscope head can be heated, discomfort of infants during auscultation is reduced, and crying and screaming of the infants are avoided, so that the auscultation efficiency and the auscultation accuracy are improved.
(2) The cold-proof cover of this device is on the rubber tube that can slide when using, overlaps when not using again outside locating the auscultation head, directly sets up heating device in the inside of auscultation head for prior art, and influences the transmission of auscultation head pickup and sound, has ensured the pickup surface temperature of auscultation head promptly, avoids it to arouse the misdiagnosis again, still protects the auscultation head, avoids colliding with the damage or drops and breaks.
Further, the method can be used for preparing a novel materialElastic bands are fixedly connected to the two radial sides of the auscultation head, and the free ends of the two elastic bands are fixedly bonded with a magic tape hair surface and a magic tape hook surface respectively.
Through the arrangement, when the infants resist auscultation, the auscultation head can be attached to a proper position of the skin by parents of the infants, and then the infants are fixed by the elastic band, so that the infants can not be auscultated when wriggling.
Further, the method can be used for preparing a novel materialAnd a plurality of lamp beads are arranged at the periphery of the warm-keeping sleeve and are connected with the storage battery through wires.
Through the arrangement, the luminous lamp beads can attract the attention of infants, and the interference of the light bulbs on auscultation is avoided.
Further, the method can be used for preparing a novel materialThe middle sunken section of the spring piece is symmetrically provided with two connecting rods, the two connecting rods are in threaded connection with the same sleeve, and the threads of the two connecting rods are opposite in screwing direction.
Through the arrangement, due to the elastic action of the spring piece, the larger the included angle between the two ear tubes is, the larger the clamping force is, and if the distance between the two ears of a doctor is too large, the stethoscope is too tight and uncomfortable to wear; if two ears of doctor apart from the undersize, the spring leaf can not initiatively retract, will lead to wearing the shakiness, and connecting rod and telescopic cooperation, the tight degree of clamp of adjustable ear pipe, and then reduce the clamp force of earplug to doctor's ear, guarantee simultaneously to dress firm, improve and use the travelling comfort.
Further, the method can be used for preparing a novel materialAn iron ring is fixedly sleeved on the rubber pipe between the heat-insulating sleeve and the three-way pipe, and a permanent magnet ring is arranged at the end part of the heat-insulating sleeve close to the iron ring.
Through the arrangement, during auscultation, the heat-insulating sleeve and the iron ring can be magnetically connected together, so that the heat-insulating sleeve is prevented from sliding on the hose at will, and further the transmission of sound in the rubber hose is interfered.
