Description

Technical Field

[0001] This utility model relates to the field of otoacoustic emission screening instruments, specifically an otoacoustic emission screening instrument with a non-nutritive suction device. Background Technology

[0002] If hearing loss in children is not detected in time, it will affect their language and cognitive functions, and even their future personal development. It will also have a certain impact on family finances and family harmony, and may also place a certain burden on society. In addition, because the tissues and organs of newborns are not fully developed, their cochlear hair cells and auditory centers are more sensitive to ischemic and hypoxic stimuli, making them more prone to hearing damage. Therefore, the purpose of hearing screening is to achieve early detection, early diagnosis and early intervention of congenital hearing loss, which plays an important role in preventing deafness and speech development disorders, thus requiring the use of otoacoustic emission screening instruments.

[0003] Existing otoacoustic emission screening instruments are inconvenient to use by soothing infants, causing them to be unable to remain quiet during use, which affects the test results and reduces the pass rate of the 42-day hearing screening rescreening for newborns. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An otoacoustic emission screening instrument with a non-nutritive sucking device includes a body 1, a fixing block 3, a nipple 4, and a connecting mechanism 5. The fixing block 3 is disposed on one side of the body 1, and the nipple 4 is connected to the fixing block 3 through the connecting mechanism 5. A controller 2 is provided on the front of the body 1, and the controller 2 is electrically connected to the body 1. The connecting mechanism 5 includes a slot 6, a threaded post 7, a limiting block 8, a sliding groove 9, a spiral rod 10, a slider 11, a motor 12, and a connecting rope 13. The slot 6 is formed on the fixing block 3, and one end of the threaded post 7 is threadedly connected to the inner wall of the slot 6. The other end of the groove 7 is connected to one end of the limiting block 8, and the other end of the limiting block 8 extends into the slot 6. The sliding groove 9 is formed on the top of the fixed block 3. One end of the slider 11 is slidably connected to the sliding groove 9, and the other end of the slider 11 abuts against one end of the limiting block 8. The motor 12 is mounted on the fixed block 3, and the output end of the motor 12 is connected to one end of the spiral rod 10. The other end of the spiral rod 10 passes through the slider 11 and is located inside the sliding groove 9. One end of the connecting rope 13 is connected to the limiting block 8, and the other end of the connecting rope 13 is connected to the nipple 4.

[0023] In use, first, turn on the main body 1. The main body 1 is a standard otoacoustic emission screening instrument available on the market; its specific structure and working principle are well understood by those skilled in the art and will not be described in detail here. Then, feed the nipple 4 into the baby's mouth to soothe the baby. Once the baby is calm, the main body 1 can be used to test the baby. The controller 2 controls the main body 1, which will not be described in detail here. The main body 1 also has a built-in battery to power the main body 1 and motor 12. A charging port is provided on the main body 1 to charge the battery. After use, the nipple 4 needs to be sterilized. It should also be sterilized before the next baby uses it. Hot water or soapy water can be used for sterilization; no specific restrictions are made here. When the nipple 4 becomes damaged after prolonged use and needs replacement, first start the motor 12 to rotate the screw rod 10, causing the slider 11 to move in the groove 9. Slide the slider 11 upwards to separate it from the limiting block 8. Then, twist the limiting block 8 to make the limiting rod drive the threaded column 7 to rotate, causing the threaded column 7 to separate from the inner wall of the slot 6. This will separate the nipple 4 of the connecting rope 13 from the equipment. Then, replace it with a new nipple 4. The new nipple 4 can be purchased from the manufacturer. The new nipple 4 comes with some components from the connecting mechanism 5, which will not be described in detail here. The motor 12 mentioned in the text is an adjustable motor 12, which will not be described in detail here. The size and shape of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in this field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail here.

[0024] To improve the sliding effect, in this embodiment, the slider 11 is matched with the groove 9.

[0025] To facilitate operation of the equipment, in this embodiment, the controller 2 is electrically connected to the motor 12.

[0026] The connecting rope 13 can be made of any material. In order to improve the strength of the connecting rope 13, in this embodiment, the connecting rope 13 is made of nylon.

[0027] The wear resistance of the outer wall of the aforementioned body 1 is poor, and the outer wall of the body 1 is prone to wear. In order to solve this problem, in this embodiment, the outer wall of the body 1 is provided with a wear-resistant layer, and the wear-resistant layer is fixedly connected to the outer wall of the body 1.

[0028] The wear-resistant layer can be made of any material. In order to improve the wear resistance, in this embodiment, the wear-resistant layer is made of PVC.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
