Description

Novel stethoscope

Technical Field

The utility model relates to a novel stethoscope, and belongs to the technical field of stethoscopes.

Background

The existing stethoscope has a single tightness adjusting mode, the tightness is adjusted by changing the length of the force arm of the ear frame tube extending out of the two sides of the ear spring, the force of the ear spring is not changed all the time, the length of the ear frame tube is limited, and the adjustable range of the tightness is still very small; the earring end pipe hoop sleeved on the earring pipe is too tight and is inconvenient to adjust, and when the earring pipe is too loose, the earring pipe is easy to shift and rotate, so that a doctor is very difficult to wear in an unused state, or the neck is difficult to endure by the earring pipe clamp, or the ear is very difficult to press by the ear hung at the back of the neck. Therefore, part doctors change the wearing mode, and the hose is directly put on the neck, but the change of the operating efficiency of the mode is reduced, the hose is wound, picked and taken when in use, the hose is thin in size, the neck oppression feeling is obvious all day long, the hose is easy to contact with the skin, the hose is not sanitary, the hose is easy to corrode, the service life of the stethoscope is shortened, and the stethoscope is easy to fall off. The stethoscope is simple, but cannot meet the requirements of all doctors on high efficiency and comfort.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model provides a novel stethoscope, which summarizes the most efficient wearing mode at present, optimizes the structure of the stethoscope, enables the adjustment of the clamping force to be more controllable and easier, improves the wearing comfort level of doctors, simplifies the structure of manufacturing elements, reduces the manufacturing cost, meets the use requirements of the doctors, is convenient to disassemble, is convenient for later cleaning and maintenance, and prolongs the service life of the stethoscope.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a novel stethoscope comprises a three-way pipe, a membrane type listening head, a rubber pipe, an ear frame pipe, ear springs and earplugs, wherein the end of the bottom of the three-way pipe is connected with the membrane type listening head through the rubber pipe, the two ends of the top are both connected with the ear frame pipe through the rubber pipe, the earplugs are arranged at the end parts of the ear frame pipe, U-shaped ear springs are arranged between the ear frame pipes, the novel stethoscope further comprises a pipe sleeve, a tightness adjusting plate, a threaded column, an elasticity knob, a jackscrew, a hinge seat, a hanging rope, a binding belt, a pressing plate and a hook plate, the ear frame pipe is an L-shaped pipe, the upper half part of the ear frame pipe is bent forwards, the upper end part of the ear frame pipe is bent inwards to be vertical to enable the end parts of the earplugs to correspond to each other, the bottom of the L-shaped pipe is connected with the rubber pipe, a rotating shaft is fixedly connected with the hinge seat, the hanging ropes are fixedly connected with the two hinge seats, the end parts of the hanging ropes are connected through the binding belt, the neck of a user is hung on the end parts of the ear springs, the side wall of the pipe sleeve is fixedly connected with the end part of the lug spring, the pipe sleeve is sleeved and inserted on the outer wall of the rubber pipe at the bottom end of the lug frame pipe and is fixed through a jackscrew screwed in through the side wall thread, a pressing plate for pressing the rubber pipe is plugged in the pipe sleeve, and the jackscrew is jacked on the pressing plate; be equipped with the elasticity regulating plate between the ear spring, the radian of elasticity regulating plate is greater than the crooked radian of ear spring, it has the hook plate to buckle at elasticity regulating plate both ends, go into some hook slot holes of seting up on the ear spring of both sides through the hook plate hook, realize the articulated with the ear spring, elasticity regulating plate bottom fixedly connected with screw thread post, the round hole has been seted up to the ear spring bottom, the screw thread post passes the round hole, it has the elasticity knob to stretch out end screw thread screw in, through rotatory elasticity knob, make the elasticity knob push down the ear spring, make the ear spring both ends use elasticity regulating plate tip to put outward as the axle center, thereby adjust the interval and the elasticity of ear spring tip simultaneously.

Hang on doctor's neck through the band, the size of band is wider, and is bigger with the area of contact of neck, and the oppression feels less, wears the doctor of stethoscope all the day, when wearing under the state of not using, the comfort level obviously promotes. Meanwhile, the name tag can be customized through the personalized design of the strap, so that more choices are provided for users, and more requirements of the users are met. When the ear-supporting tube is worn, the ear-supporting tube can be held by two hands, and the ear-supporting tube can be used after being lifted by one hand, so that the operation efficiency is inconvenient, and the ear-supporting tube is convenient for a doctor to use. And, traditional stethoscope is when using, for satisfying the demand of adjusting, the size of earmuff pipe needs the very long of design, when lifting up the stethoscope and using, whole stethoscope is with the earplug pendulum on the axle center, the focus draws close to the earplug gradually, the elasticity must be increaseed, otherwise drop easily, lead to ear oppression sense high, the influence of very big degree comfort level when using, and the regulation of this design has the ear spring to replace completely, the length of earmuff pipe has been shortened by a wide margin, and when lifting up the stethoscope and using, whole stethoscope is with the rubber tube of three-way pipe top realize warping as the buckling point, the center moves forward, ear spring bottom can directly take before the chest even, bearing part weight, the compressive force of the earplug that further alleviates, and then can reduce the elasticity, improve the comfort level of using work ear. The ear frame tube and the ear spring are fixedly connected in a fixing mode of the tube sleeve, the pressing plate and the jackscrew, and after the adjustment is completed, the corner of the ear frame tube is ensured, so that the earplug and the ear can be well adapted when being worn, and the sound leakage is avoided.

Whole device compares with traditional stethoscope, and the structure gain is not big, but the structure style takes place obvious change, and the combination of each part has formed outstanding technological effect simultaneously, has both controlled manufacturing cost, has satisfied the user demand again, has solved current stethoscope and has worn the problem unsuitable and inconvenient operation, more is fit for the doctor and uses.

The utility model has the beneficial effects that: solves the problems of the prior stethoscope that the wearing is not suitable and the operation is inconvenient, provides a novel stethoscope which is more convenient to wear and operate, adopts the most efficient stethoscope wearing mode at present, positions the ear support pipes at the two sides of the neck of a wearer, and is also lifted and taken when in use, the stethoscope head has the advantages that the stethoscope head is hung on the neck through the binding band, the stethoscope head is prevented from falling, the size of the binding band is wider, the oppressive feeling of the neck is smaller, the comfort level is higher, the neck is completely free of clamping feeling when being worn, the clamping distance and the clamping force between the ear frame tubes are adjustable, the adjusting mode is simple and efficient, accurate adjustment can be realized only by screwing the knob, the adjustment to the comfortable force by a doctor is facilitated, the turning angle of the ear frame tubes is also adjustable, and the stethoscope head is not easy to loosen after being fixed, and convenient dismantlement and equipment, the later stage clearance of being convenient for, change a and maintain, more accord with the demand in market.
