Description

Earplug for infants

Technical Field

The utility model relates to the field of earplugs, in particular to an infant earplug.

Background

With the rapid development of medical services, the application rate of Magnetic Resonance Imaging (MRI) examination for children is higher, and the popularization thereof leaves many diseases that have been difficult to examine before unconscious. However, the MRI examination is very noisy, and the noise index is as high as 120 db, which may have a certain effect on the patient. In addition, absolute cooperation of patients is required in the examination process, and the difficulty of successfully completing MRI examination is high for infants with low cooperation degree. Therefore, infants and preschool children often need to be under moderate or deep sedation or anesthesia to complete the examination, but the presence of these factors increases the failure rate of nmr examinations and the incidence of adverse events.

In order to more effectively reduce the noise generated in the examination and improve the comfort level and the success rate of the nuclear magnetic resonance examination, equipment manufacturers and medical workers provide various noise reduction methods, such as: silent magnetic resonance is used, and a cotton plug, an earphone and the like are worn on the patient. The equipment of the mute magnetic resonance is high in price and not completely free of noise, the mute magnetic resonance cannot be popularized in a short time, and in addition, the mute nuclear magnetic resonance sequence reduces the noise by reducing the output power of the equipment, so that part of image signals are sacrificed to cause the reduction of image quality; the cotton plug has poor stability, is easy to fall off and has poor noise prevention effect; the earphone can play certain syllable-dividing effect, but special earphone is mostly adult's money, is not suitable for the infant, leads to its syllable-dividing effect not good, and the earphone directly contacts the patient in the use moreover, and the rate of utilization that is superelevation leads to the earphone to be difficult to obtain strict cleaning and disinfection, especially contacts and keeps apart behind the patient, and remaining pathogenic bacteria is hiding huge cross infection risk on the earphone.

It is seen that improvements and enhancements to the prior art are needed.

Detailed Description

The utility model provides an infant earplug, which is further described in detail below by referring to the accompanying drawings and embodiments in order to make the objects, technical schemes and effects of the utility model clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, the present invention provides an earplug for infants.

An infant earplug is characterized by comprising an insert 1 and a clamping piece 2; the front part 11 of the insert is in a circular truncated cone shape, and the outer diameter of the front part is gradually increased from front to back; the rear part 12 of the insert is adapted to the external auditory canal of the infant, the rear part 12 of the insert is a downwardly curved cylinder with a horizontal S-shaped trend; the rear part 12 of the insert is connected with the clip 2; the earplug is made of elastic materials. The external auditory meatus of the infant is not completely developed, it goes different from that of the adult, its inside is more curved, and the length and width of the external auditory meatus are smaller than those of the adult, so that the adult earplug is not suitable. The earplug is provided with the insertion piece 1 matched with the external auditory canal of the infant, and the truncated cone-shaped design at the front part of the earplug is beneficial to the insertion piece 1 to extend into the external auditory canal and reduce the stimulation to the external auditory canal; the rear part of the earplug is a cylinder which is bent downwards and has a horizontal S-shaped trend, the shape of the cylinder is matched with that of an external auditory canal of an infant, and the earplug 1 can be tightly attached to the external auditory canal after being worn, so that the earplug has a better sound insulation effect. Joint spare 2 and the concha chamber adaptation of external ear can provide certain syllable-dividing effect, is convenient for wearing and the excision of earplug simultaneously. Specifically, the elastic material is the sound bubble cotton of inhaling of kick-backing slowly, and the cotton softness of its compliance of inhaling of the sound bubble of kick-backing slowly is good, and the resilience is slow, more is applicable to the skin and is more sensitive infant, and the loose porous structure of cotton inside of bubble can exert good sound absorption effect. In addition, the low-resilience sound-absorbing foam is low in price, so that the manufactured earplug can be used as a disposable product, and cross infection caused by repeated use of the earplug is avoided. The earplug can be disinfected before use to avoid virus and bacteria pollution, and the clamping piece 2 for grabbing the earplug can be used for operation when the earplug is worn by an infant, so that the insertion piece 1 can be prevented from being polluted when the earplug is taken out and operated.

Further, the front part 11 of the insert has a diameter of 3 to 3.5mm and a length of 3 to 4 mm. The diameter of the rear portion 12 of the insert is 5-6 mm, and the length is 5-6 mm. The front part of the earplug is thinner and gradually increases backwards, so that the earplug can fully fill the external auditory canal without ear expansion, and meanwhile, the earplug can relieve stimulation to the infant who is sensitive to the internal auditory vestibule to a certain extent. The external auditory canal of the infant is not completely developed and is narrow, and the total length is about 21-25 mm. The front portion 11 of the insert should not be too large, otherwise it would be undesirable to extend into the external ear canal; the rear part 12 of the insert is compressed after extending into the external auditory canal and generates a certain resilience, so that the insert 1 can be tightly attached to the wall of the external auditory canal, and the noise-proof and sound-proof effects are improved. The total length of the insert 1 should not be too large, otherwise the foreign body in the external auditory canal is easily pushed into the external auditory canal too much, the external auditory canal is blocked, the hearing is affected, and the tympanic membrane may be damaged in serious cases.

Further, joint spare 2 is pea form, and its length is 7 ~ 8mm, with the concha chamber adaptation of external ear. The joint piece 2 adopts pea form design, matches more with infant's external auditory canal profile, helps wearing stably and improves noise reduction.

In one embodiment, the clip 2 includes a clip main body 21 and a handle 22, the clip main body 21 is in a pea shape, the front portion of the clip main body 21 is connected to the insert 1, and the rear portion thereof is connected to the handle 22. The concha cavity of the infant is small, the clip 2 is not easy to grab after being sunk, and the earplug can be taken out more easily by arranging the handle 22 extending to the outside of the ear.

Further, the handle 22 with the junction of joint spare main part 21 is arc and downwardly extending, the junction is used for the joint on the intertragic notch of auricle, can make the earplug wear the back more stable, also is convenient for take out.

In one embodiment, the insert 1 and the clip 2 are both hollow. The elastic material can be but not limited to soft silica gel, and the earplug adopts a hollow structure, and the inside of the hollow structure can provide a deformation space, so that the softness of the earplug is improved, meanwhile, the material can be saved, and the production cost is reduced.

It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the appended claims.
