Description

Hearing screening instrument ear muff fixing device

Technical Field

The utility model relates to a hearing examination technical field, concretely relates to hearing examination appearance ear muff fixing device.

Background

The hearing screening is an objective, rapid and noninvasive examination performed in a natural sleeping or quiet state after birth of a newborn through electrophysiological detection of otoacoustic emission, automatic auditory brainstem response, acoustic impedance and the like. And the places with the condition should be screened generally, and the places without the condition should be screened for at least the high-risk newborn suffering from the hearing impairment according to the local conditions.

Currently, neonatal hearing tests generally employ otoacoustic emission and automated auditory brainstem response. Cover the whole auricle of neonate with the ear muff according to instrument operation flow behind the clean external auditory canal, the inspection result is directly influenced to the laminating degree of ear muff and skin. The edge of the earmuff is well fixed by the adhesive when the earmuff is used for the first time, but the adhesive is removed when the earmuff is disinfected for the purpose of disinfection.

In order to fit the ear muffs to the skin of the child, clinical nurses typically use: the small towel, bath towel and the like are folded and placed outside the ear muffs to enable the ear muffs to be attached to the skin by external force. Secondly, the ear muffs are fixed by cloth strips around the head. While achieving the desired goals, there are a number of problems: the operation is complicated, and the ear muffs are placed in the auricles and need to be taken for secondary fixation. Secondly, the disinfection cost is increased, and small towels, bath towels and cloth strips for fixing need to be discarded in order to prevent cross infection. The degree of fitting of the earmuffs to the skin has direct relation with how many peripheral fixtures such as towelettes, bath towels and the like, the more required articles are better in the degree of fitting, the more sterile articles are consumed, meanwhile, the more articles are accumulated on the two sides of the head, the observation of the state of illness is not facilitated, and the bedspread is messy. The fixture is too few, and patient's head rocks slightly just can lead to the ear muff dystopy, influences the ear muff laminating degree, influences the inspection result. Therefore, the problem that the ear muffs of the hearing screening instrument are inconvenient to fix during the hearing screening of the newborn exists in the prior art.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1, a hearing screening instrument earmuff fixing device includes a head-mounted bracket 10 and fixing covers 20 respectively connected to both ends of the head-mounted bracket 10.

The head-mounted support 10 is integrally arc-shaped and is relatively attached to the brain of the newborn, so that the head-mounted support is conveniently fixed on the head of the newborn. Head-mounted support 10 includes mount 11 and carriage 12, and carriage 12 is connected at the both ends of mount 11, the one end and the fixation clamp 11 sliding connection of carriage 12, the other end and fixed cover 20 fixed connection to adjust the size of head-mounted support 10, the neonate of the different head sizes of being convenient for uses.

Referring to fig. 2, 3 and 4, the stationary cover 20 includes a contact side 21 and a distant side 22, the contact side 21 being in contact with the concha of the neonate. The soft filler 31 is arranged inside the fixing cover 20, and the soft filler 31 can be made of sky cotton, so that the contact side 21 of the fixing cover 20 can be prevented from excessively pressing the outer ear of the newborn.

A through hole 23 is opened at the middle position of the fixed cover 20, and the diameter of the through hole 23 may be varied or uniform. The end of the through hole 23 near the far side 22 is threaded and is threadedly connected with a pressing piece 24, and the pressing piece 24 can move in the through hole 23. The inner wall that the one end that the perforating hole 23 is close to the contact side 21 is connected with elastic layer 25, and the edge of elastic layer 25 and the inner wall of perforating hole 23 are connected, and the one side that elastic layer 25 is close to the contact side 21 is used for placing the hearing screening appearance ear muff to through extruded piece 25's removal, can cause the extrusion to elastic layer 26, thereby make the hearing screening ear muff hug closely neonate's external ear. The soft filler 31 is arranged in the fixing cover 20, and the material of the soft filler 31 can be space cotton or sponge, so that the compression injury to the external ear of the neonate is avoided.

Still be equipped with flexible spheroid 26 in the intermediate position of extruded article 24 and elastic layer 25, flexible spheroid 26 is whole to be the ellipse, thereby flexible spheroid 26 is used for avoiding extruded article 24 directly to extrude elasticity 25 and causes the damage of elastic layer 25, makes the extrusion deformation of elastic layer 25 more laminate neonate's external ear.

The extrusion piece 24 comprises an extrusion end 27, a connecting section 28 and a rotating end 29 which are connected in sequence, wherein the extrusion end 27 is close to the flexible ball 26, the edge of the connecting section 28 is in threaded connection with the inner wall of the through hole 23, and the whole extrusion piece 24 can be driven to rotate through the rotating end 29. The sectional dimensions of the pressing end 27 and the rotating end 29 are smaller than those of the connecting section 28, so that the pressing member 24 is prevented from being inserted into the through hole 23 as a whole and being taken out with difficulty in rotation. The edge of the rotating end 29 is provided with knurls 30 so as to facilitate the force to drive the rotating end 29 to rotate, thereby controlling the meshing depth of the extrusion piece 24 and the through hole 23. In other embodiments of the present invention, the edge of the connecting section 28 and the inner wall of the through hole 23 can be slidably connected.

The utility model discloses an operation process: (1) the surface of the elastic layer 25 that places the hearing screener earmuffs in the through holes 23 near the contact side 21; (2) fixing the head-wearing bracket 10 on the head of a newborn, and adjusting the relative sliding of the fixing frame 11 and the sliding frame 12 according to the specific head size; (3) the pressing member 24 is rotated by applying force to the knurls 30, so that the meshing depth of the pressing member 24 in the through hole 23 is adjusted; (4) the extrusion end 27 extrudes the flexible ball body 26, and the flexible ball body 26 extrudes the elastic layer 25, so that the ear muff of the hearing screening instrument is tightly attached to the external ear of the newborn, and the hearing screening is carried out.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
