Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hyperbaric oxygen therapy, in particular to a device for preventing ear barotrauma during hyperbaric oxygen therapy. Background Art
[0002] Hyperbaric oxygen therapy is a method of treating hypoxic diseases and related disorders by breathing pure oxygen or high-concentration oxygen in a high-pressure environment (exceeding normal pressure). Changes in the pressure in the hyperbaric oxygen chamber will cause an imbalance in the pressure inside and outside the patient's eardrum, which can easily lead to complications such as middle ear barotrauma. Therefore, an ear barotrauma prevention device is needed to protect the ear canal and balance the pressure inside and outside the ear canal.
[0003] In the prior art, a Chinese patent with patent publication number CN211797221U discloses an ear canal protection device for balanced hyperbaric oxygen therapy, including a sponge earplug, with pressure relief holes on both sides of the bottom end of the sponge earplug, a protective shell located on the outer side of the pressure relief hole on the top of the sponge earplug, a baffle on the top of the protective shell, a mounting block fixedly installed on the bottom end of the baffle, a spring fixedly installed on the right end of the mounting block, and a handle fixedly installed on the top end of the baffle.
[0004] Although the above patent can expose the pressure relief hole by pulling the pull ring to balance the pressure inside and outside the ear canal, the pull ring is only pulled to relieve pressure when discomfort is felt. In actual use, it is impossible to monitor the pressure values inside and outside the ear canal and then automatically relieve pressure. There is a situation where the pressure inside the ear canal is too high and the pressure is not relieved in time, causing ear barotrauma. Therefore, we propose a hyperbaric oxygen therapy ear barotrauma prevention device. Utility Model Content

[0012] Furthermore, a connecting rod is fixedly connected to the outer surface of the pressure-proof earmuff, and one end of the connecting rod is fixedly connected to the earmuff rod.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] 1. In the utility model, a pressure sensor is provided to monitor the change of the air pressure in the ear canal. The motor can drive the turntable to rotate, so that the third pressure relief hole moves to gradually expose the second pressure relief hole for pressure relief.

[0024] The effect achieved by the entire embodiment 1 is that as the air pressure in the hyperbaric oxygen chamber continues to increase, the pressure sensor 11 can monitor the air pressure change inside the ear canal. When the pressure sensor 11 detects that the air pressure change in the ear canal exceeds the threshold, it transmits a signal to the control center to control the motor 10 to work, drive the gear 19 to rotate, and the gear 19 is engaged with the outer gear ring 18, thereby driving the outer gear ring 18 and the turntable 9 to rotate, so that the third pressure relief hole 16 opened on the turntable 9 moves to gradually communicate with the second pressure relief hole 15, exposing the second pressure relief hole 15 for pressure relief. After detecting that the air pressure returns to normal, the motor 10 drives the third pressure relief hole 16 to continue to move.

The pressure in the ear chamber changes more evenly and slowly, and the occurrence of complications such as middle ear barotrauma is prevented.
[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the difference between this embodiment and embodiment 1 is that a display screen 7 is fixedly connected to one side of the buffer plate 4; a sealing ring 2 is fixedly connected to one side of the anti-pressure earmuff 1; a connecting rod 5 is fixedly connected to the outer surface of the anti-pressure earmuff 1, and one end of the connecting rod 5 is fixedly connected to the earmuff rod 6.

The sealing ring 2 fits the outside of the ear to improve the sealing performance of the device. After wearing the device, the patient enters the hyperbaric oxygen chamber. As the air pressure in the hyperbaric oxygen chamber continues to increase, the pressure sensor 11 can monitor the air pressure changes in the ear canal, and the measured value will be displayed on the display screen 7 in real time. When the pressure sensor 11 detects that the air pressure change in the ear canal exceeds the threshold, it transmits a signal to the control center to control the motor 10 to work, drive the gear 19 to rotate, and the gear 19 is meshed with the outer gear ring 18, thereby bringing The movable outer gear ring 18 and the turntable 9 rotate, so that the third pressure relief hole 16 opened on the turntable 9 moves to gradually connect with the second pressure relief hole 15, exposing the second pressure relief hole 15 for pressure relief. After detecting that the air pressure returns to normal, the motor 10 works to drive the third pressure relief hole 16 to continue to move to separate from the second pressure relief hole 15, covering the second pressure relief hole 15, thereby achieving the effect of balancing the internal and external pressures. The pressure relief chamber 12, the connecting chamber 13, the first pressure relief hole 14 and the second pressure relief hole 15 are connected in sequence.
