Description

tracheostomy mask

Technical field

The present invention relates to the technical field of medical devices, and relates to a tracheostomy mask, and in particular to a tracheostomy mask that can heighten and adjust the exhalation hole.

Background technique

Tracheotomy generally refers to tracheotomy, which is very important in the rescue process of critically ill patients. Tracheotomy is a surgery that incises the front wall of the cervical trachea and allows breathing through the newly established channel that reconnects with the outside world. It is mainly used to rescue patients with laryngeal obstruction, restore airway patency, and ensure normal ventilation of the patient. After tracheostomy patients are taken offline, they need to use a tracheostomy mask for oxygen inhalation. The tracheostomy masks currently used clinically cannot adjust the height and only have one through hole for both exhalation and sputum suction. Some use adjustable tracheostomy tubes. For patients, the outer end of the tube is longer, causing the tracheostomy mask to be pushed up by the outer end of the tracheostomy tube, causing the tracheostomy mask to have a poor oxygen supply effect and almost losing its oxygen supply function.

Faced with these problems, a variety of improved designs have been proposed. For example, patent CN201101790Y discloses a tracheostomy mask. A convex transparent hemispherical air-mixing chamber is formed in the middle of the arc-shaped mask body, and the hemispherical air-mixing chamber is equipped with The oxygen inlet tube can be rotated at will and has an air inlet and outlet, which facilitates the connection with the oxygen tube and atomizer, allowing the patient to breathe independently through the air inlet and outlet, and the aerosol particles formed by oxygen or atomization are mixed in a hemispherical The air in the chamber mixes with the air and then enters the human body, simulating natural breathing. CN213642668U discloses a laryngeal mask for tracheostomy. A hemispherical air mixing chamber is provided in the middle of the mask body. An extension tube is extended from the middle of the hemispherical air mixing chamber. The humidifying atomizing bottle is connected to the extension tube through a threaded connector on the bottle cap. The oxygen tube is connected to the threaded connector at the bottom of the humidification nebulizer bottle, which can facilitate medical staff or family members to clean the sputum flowing from the patient's wound without removing the laryngeal mask, which solves the problem of easy use of the humidification nebulizer bottle after being used for a long time. Leakage problem. CN217745290U discloses a height-adjustable oxygen atomization mask for tracheostomy patients, which is provided with silicone pads on the inner wall sides of the mask body, a telescopic breathing tube in the middle of the mask body, and a breathing mask at one end of the telescopic breathing tube. , the outer wall of the breathing mask is provided with an air guide tube, and one end of the air guide tube is provided with a rotating mechanism. The telescopic breathing tube and the rotating mechanism are set in a coordinated manner. The telescopic breathing tube is suitable for tracheostomy cannulas of different exposed lengths. Through the air guide tube The rotation facilitates different oxygen atomization inhalation angles for patients and improves the stability of the oxygen atomization mask.

However, the above design cannot fully improve the oxygen supply effect of the tracheostomy mask, is difficult to adapt to the respiratory needs of patients with different breathing conditions, cannot prevent coughed secretions from splashing out, and is not convenient for sputum suction.

Detailed ways

The tracheostomy mask is a device used by tracheostomy patients to inhale oxygen. However, the existing tracheostomy masks currently used clinically in hospitals have many shortcomings. For example, the sputum flowing out and coughed up from the patient's tracheal incision is inconvenient to clean and needs to be removed. The patient's throat can be cleaned only by opening the mask; because the height cannot be adjusted, it is easy to be jacked up by the outer tracheostomy tube, resulting in poor oxygen supply effect; the exhalation state cannot be adjusted according to the patient's differences and feelings. Overcoming these shortcomings can greatly improve practicality. Sexuality and patient experience.

The tracheostomy mask provided by the present invention has the function of heightening and adjusting the exhalation state. By setting two exhalation holes (air outlet, exhaust hole) with adjustable air output/aperture size and a one-way exhaust hole, Adding a sputum suction port that can be opened and closed and setting up a telescopic tube can be used to change the height of the tracheostomy mask to suit patients with different breathing states or breathing needs, which improves the practicality of the tracheostomy mask and improves the performance of the tracheostomy mask. It has an oxygen supply effect and prevents coughed up secretions from splashing out, making it convenient for sputum suctioning.

For convenience of description, the exhalation hole (exhaust hole) whose air output volume/pore size can be adjusted may be referred to as "adjustable exhaust hole" in this article.

As used herein, the term "tracheostomy mask" may also sometimes be referred to as a "face mask," "tracheostomy mask," or "tracheostomy shield." For simplicity of description, it can be referred to as "mask". They have the same meaning and can be used interchangeably. Similarly, the term "band" can also be called "fixed band", "band" or "elastic cord"; the term "exhalation hole (mouth)" can also be called "air outlet (mouth)" or "exhaust hole". pores" etc.

Improvements in this design include the provision of exhalation holes on the left and right sides of the tracheostomy mask, and the way the exhalation holes discharge air can be adjusted by rotating the dial. There is a sputum suction hole in the middle position, which can be closed when not in use. Moreover, the tracheotomy mask has a telescopic extension area, which can increase the placement position of the tracheotomy mask. The adjustment dial on the exhalation hole can effectively adjust the exhalation volume/aperture size and air outlet method to adapt to the breathing needs of different patients. For example, when the patient has high oxygen requirements, one-way exhalation can be selected to reduce air entrainment and dilution. The concentration of the inhaled gas ensures the oxygen concentration of the inhaled gas; when the patient accumulates carbon dioxide, he or she can choose a large-aperture exhalation hole to increase gas circulation; the type of bilateral exhalation holes can be freely selected to reduce the risk of coughing. Secretions splash out.

The tracheostomy mask of the present invention utilizes an exhalation hole with adjustable aperture size and air outlet mode, and a telescopic and increased design. It can be applied to patients with different tracheostomy tubes and different breathing states, conforms to clinical indicators, and improves the applicability of the mask.

Those skilled in the art can easily understand that the difference between the tracheostomy mask of the present invention and the prior art mainly lies in the improvement of the mechanical structure. Each component can adopt the same functional components of the prior art mask or other general medical exhalation equipment. For example, the above-mentioned mask body can be made of transparent or opaque soft polymer materials such as medical PVC materials, silicone, etc.; the turntable can be made of hard plastic. The selection of this prior art material will not increase the production cost too much and is economically beneficial.
