Abstract

The utility model relates to the technical field of medical equipment, in particular to a stethoscope with noise filtering function, which comprises an earphone, a sensing cavity head, a sound guide pipe, a sound guide branch pipe and a sound wave selection and filtration device, wherein one end of the sound guide pipe is connected with the sensing cavity head, the other end of the sound guide pipe is connected with the sound guide branch pipe through a joint, one end of the sound guide branch pipe, which is far away from the joint, is connected with the earphone, and the sound wave selection and filtration device is arranged on the sound guide pipe; in the auscultation process, when the patient cries and screels and does not cooperate, the noise with some unnecessary wave bands can be selectively filtered out due to the arrangement of the sound wave selection filtering device, and the crying and screeing sound wave band is different from the wave bands emitted by the viscera such as the lung, the heart, the abdomen and the like in the practical application; therefore, during diagnosis, the sound wave selection and filtration device can filter out crying and screaming sound waves, so that the influence on the auscultation of medical staff is reduced, and the diagnosis effect is better.

Description

Stethoscope with noise filtering function

Technical Field

The utility model relates to the technical field of medical equipment, specifically a stethoscope with noise filtering function.

Background

The stethoscope is a necessary instrument for physical examination of a clinician, and comprises two receivers, a sensing cavity head and a hollow pipeline connected between the receivers and the sensing cavity head, and the stethoscope amplifies the heart vibration of a human body after a film on the surface of the sensing cavity head is contacted with the human body, and transmits the amplified vibration to the ears of the clinician through air (without external interference) in a closed space, so that the clinician can clearly hear the sound in a patient body, and the condition in the patient body is judged. In the actual pediatric diagnosis and treatment process, the infant cannot accurately describe the disease condition, so that the diagnosis of a pediatrician is difficult, and the stethoscope can help the pediatrician to collect the pathological features of the lung and other organs; but when the infant is crying and is not matched with the infant, the auscultation effect is not ideal, so that the diagnosis is difficult, and even the cases of unknown diagnosis or misdiagnosis and the like occur in serious cases; thereby causing unnecessary doctor-patient disputes.

SUMMERY OF THE UTILITY MODEL

To the weak point among the above-mentioned prior art, the utility model aims at providing a stethoscope, makes it have the function of noise filtration.

In order to solve the technical problem, the utility model provides a pair of stethoscope with noise filtering capability, select filter equipment including earphone, sensing chamber head, leading note pipe, leading note branch pipe and sound wave, leading note pipe one end is connected with sensing chamber head, and the other end connects with leading note branch connection through one, leading note branch pipe keep away from the one end that connects with the earphone is connected, the sound wave selects filter equipment to set up on the leading note pipe.

The quantity of leading sound branch pipe is two, and two it all is connected with leading sound pipe through connecting to lead sound branch pipe.

The sound guide branch pipes are provided with tightening belts, and the tightening belts are connected with the two sound guide branch pipes through fixing clamping sleeves arranged at the two ends of the tightening belts.

The tightening belt is provided with a tightening device, and the tightening device is provided with a fixing clamp.

The earphone is an earplug, and a protective sleeve is sleeved on the earphone.

The protective sleeve is made of a cloth material with a sponge fluffy structure.

The utility model has the advantages that:

the utility model discloses in the practical application in-process, medical staff wears the earphone, makes sensing chamber head contact the human body to carry out the auscultation to the patient, and in the auscultation process, when the patient appears crying and screaming and does not cooperate, because the setting of sound wave selection filter equipment, can selective filtration go out some noises that do not need the wave band, and in the practical application, the sound wave band of crying and screaming and noise is different with the wave band that viscera such as lung, heart, belly sent; therefore, during diagnosis, the sound wave selection and filtration device can filter out crying and screaming sound waves, so that the influence on the auscultation of medical staff is reduced, and the diagnosis effect is better.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-2, the utility model discloses a stethoscope with noise filtering function, select filter equipment 5 including earphone 1, sensing chamber head 2, leading note pipe 3, leading note branch pipe 4 and sound wave, leading note pipe 3 one end is connected with sensing chamber head 2, and the other end is connected with leading note branch pipe 4 through a joint 6, leading note branch pipe 4 keep away from the one end that connects 6 with earphone 1 connects, filter equipment 5 setting is selected to the sound wave is in on the leading note pipe 3.

The number of the sound guide branch pipes 4 is two, and the two sound guide branch pipes 4 are connected with the sound guide pipe 3 through connectors 6; the number of the sound guide branch pipes 4 is two, and the two sound guide branch pipes 4 are connected with the sound guide pipe 3 through the connectors 6, so that the auscultation of medical staff is facilitated.

The sound guide branch pipes 4 are provided with tightening belts 7, and the tightening belts 7 are connected with the two sound guide branch pipes 4 through fixing clamping sleeves 8 arranged at two ends of the tightening belts; the tightening belt 7 is mainly used for tightening the sound guide branch pipe 4 when medical staff brings the telephone receiver 1 for diagnosis, so that the telephone receiver 1 and the sound guide branch pipe 4 are prevented from falling, and the medical staff can conveniently diagnose.

The tightening belt 7 is provided with a tightening device 9, and the tightening device 9 is provided with a fixed clamping piece 10; the tightening device 9 is mainly used for retracting the loosened tightening belt 7 to tighten the tightening belt 7, so that the medical staff can operate the tightening belt conveniently; the fixing clip 10 is mainly used for fixing the tightening belt 7 and preventing the sound guide branch tube 4 and the receiver 1 from falling off due to the fact that the tightening belt 7 is loosened again.

The earphone 1 is an earplug, and a protective sleeve 11 is sleeved on the earphone 1.

The protective cover 11 is made of a cloth material having a sponge-like bulky structure.
