Problems solved by technology
The existing electronic larynx is a hand-held semiconductor device. In order to make a sound, the end of the electronic larynx needs to be placed on the best pronunciation point on the front of the neck, and the sound is transmitted to the pharynx to form a language; every time the patient When you need to speak, you have to lift the electronic throat, which is inconvenient to use

The invention relates to wearing equipment used after operation of pharyngolaryngeal cancer. The wearing equipment comprises a dust prevention cover and an electronic larynx sound production device, wherein the dust prevention cover comprises a cover-shaped casing; the casing is provided with densely-distributed air holes; filter cotton is arranged on the inner side of the casing; the edge parts on the two sides of the casing are connected with the two ends of a bandage; the electronic larynx sound production device comprises a power supply, a vibrating sensor, an A / D conversion module, a PWMgeneration module and a sound production board, arranged in a housing; the vibrating sensor, the A / D conversion module, the PWM generation module and the sound production board are sequentially electrically connected and are connected with the power supply; the housing takes the shape of a ring; the casing is positioned at the center of the housing and is connected with the housing; and the housing is provided with a sound production hole. The dust prevention cover and the electronic larynx sound production device are integrated, the electronic larynx sound production device is always stuck tothe neck part of a patient, an electronic larynx does not need to be lifted up when the patient needs to speak, and therefore, the wearing equipment is convenient to use.
Description
technical field [0001] The invention relates to the field of medical auxiliary devices, in particular to a postoperative wearable device for throat cancer. Background technique [0002] Patients after total laryngectomy have their vocal cords removed at the same time as their tumors are removed. While suffering physical blows, their normal language communication function is also lost, and their quality of life is greatly reduced. Electronic larynx can make voice and improve the quality of life of patients after total laryngectomy. The existing electronic larynx is a hand-held semiconductor device. In order to make a sound, the end of the electronic larynx needs to be placed on the best pronunciation point on the front of the neck, and the sound is transmitted to the pharynx to form a language; every time the patient When you need to speak, you have to lift the electronic throat, which is inconvenient to use. [0003] In addition, patients with pharyngectomy will leave a ci...
