A filter device for tracheostomy

Abstract

The invention provides a tracheostoma filter plant. A throat-excised patient can breathe by the aid of the tracheostoma filter plant. The tracheostoma filter plant comprises a tubular base, an end cover and a breathable film. The tubular base comprises a matching end and a connecting end, the matching end is connected with tracheostoma for the throat of the patient, the connecting end is connected with the end cover, a nanometer breathable net is arranged in the tubular base, the tubular base and the end cover are made of silicon materials, and the breathable film sleeves the outer wall of the tubular base and is adhered with the throat of the patient. The tracheostoma filter plant has the advantages that the tracheostoma filter plant can cover the neck of the patient instead of a sleeve or gauze, the nanometer breathable net is arranged in the tracheostoma filter plant, accordingly, tracheal secretions can be prevented from spilling, or foreign bodies can be prevented from entering the trachea of the patient, sterilization effects further can be realized, and the tracheostoma filter plant does not need to be changed frequently and is easy and convenient to use.

Description

Technical field [0001] The present invention relates to medical equipment, in particular to a tracheostomy filter device for patients whose larynx is removed. Background technique [0002] Normal people breathe through the nasal cavity to inhale air into the trachea through the pharynx and larynx. The nose hair at the front of the nasal cavity can block the entry of large dust and foreign bodies. In addition, normal people rely on the vibration of the throat vocal cords and coordinate with the resonance of the pharynx, oral cavity and nasal cavity. Kind of voice. [0003] Laryngeal cancer is a malignant tumor of the head and neck that occurs in the larynx. It is clinically manifested as hoarseness and difficulty breathing, which is harmful to the human body. Its incidence accounts for 1% to 2% of systemic malignant tumors. Because the lesion is in the larynx, patients will mistakenly think it is a common disease such as pharyngitis in the early stage and fail to pay attention to i...

Problems solved by technology

In general, in order to prevent tracheal secretions from overflowing or foreign bodies from easily entering the trachea, the existing tracheostomy protection measures are to wear a tracheal tube cover or cover with gauze on the neck of the patient after surgery for a long time, but neither of these two methods It is very ideal and brings a lot of inconvenience to the life of patients; and because the tracheostomy is a sensitive part, it is easy to cause infection or disease, so a safer and more reliable device is needed to make up for the shortcomings of the existing technology
