Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to a mucosa-preventing occupational exposure tracheostomy oxygen inhalation mask. BACKGROUND

[0002] The commonly used oral-nasal oxygen inhalation mask is mainly designed for oral-nasal oxygen inhalation, and has many problems when used for tracheostomy patient oxygen inhalation. It can only match the face and nose structure of most patients, and for tracheostomy patients, especially those with short necks, the mask volume is too large to easily resist the mandibular or chest skin, causing pressure injury and abnormal body sensation.

[0003] The foregoing mask needs to be fixed around the neck, which is complicated to operate and easy to dislodge.

[0004] When sputum is sucked from the tracheostomy patient, the existing mask needs to be removed from the mask for sputum suction, which can easily cause strong cough reflex in patients, and repeated sputum suction without oxygen inhalation can easily cause hypoxemia when the sputum volume is large. It needs to be paused for sputum suction and oxygen inhalation correction before being performed again, causing patient condition fluctuation, and in severe cases, it can cause brain hypoxia and endanger life.

[0005] The most critical is that sputum and droplets are easily splashed when sputum is sucked from the mask, the spraying distance is far, and cross infection is easily caused, and special infection patients can also cause mucosa occupational exposure of medical staff.

[0006] The prior art has the following problems:

[0007] 1) The mask of the prior art needs to be fixed around the neck, which is complicated to operate and easy to dislodge;

[0008] 2) The existing mask needs to be removed for sputum suction, which can cause hypoxia and endanger the life of the patient;

[0009] 3) The mask of the prior art is easy to cause sputum and droplets to splash when sputum is sucked after being removed, which can easily cause cross infection and mucosa occupational exposure of medical staff. INVENTION CONTENTS

[0010] The utility model provides a mucosa-preventing occupational exposure tracheostomy oxygen inhalation mask with adjustable fixing support, arbitrarily rotatable connection tail end oxygen inhalation pipe and sputum suction function for solving the problems in the foregoing background art, and the utility model is realized by the following technical scheme:

[0011] The utility model discloses a kind of anti-mucosa occupational exposure type gas cutting oxygen masks, including the mask main body with upper and lower ends having opening, with the upper opening of mask main body 360 degree rotatable connection's rotating oxygen supply device, set on the upper surface of rotating oxygen supply device inverted cone sputum suction tube, set on the upper surface of inverted cone sputum suction tube switchable closure, be provided with two L type adjustable type fixed clamps in the lower opening of mask main body two sides, be connected in the oxygen inhalation tube connecting portion on the side wall of rotating oxygen supply device.

[0012] As further improvement, the upper end opening of the mask main body is circular, and the lower end opening is elliptical, and the whole is umbrella-shaped structure with small upper opening and large lower opening, and the upper part of the mask main body and the lower part of the rotating oxygen supply device are mutually embedded structure for 360-degree rotary connection between the mask main body and the rotating oxygen supply device.

[0013] As further improvement, the rotating oxygen supply device is a hollow cylindrical structure with a lower end opening communicating with the mask main body.

[0014] As further improvement, the lower opening of the inverted cone sputum suction tube extends to the inside of the mask, one end of the oxygen inhalation tube connecting portion is connected with the oxygen inhalation tube through a threaded structure, and the other end is fixed on the rotating oxygen supply device and communicates with the inside of the rotating oxygen supply device.

[0015] As further improvement, the inverted cone sputum suction tube is a hollow structure with an inner diameter greater than or equal to 5 mm.

[0016] As further improvement, the lower end opening of the mask main body is elliptical, with an upper and lower diameter of 3-4 cm and a horizontal diameter of 4-5 cm, for protecting the skin of the lower jaw and the upper chest when used by patients with short necks.

[0017] As further improvement, the lower end opening of the mask main body is elliptical, with an upper and lower diameter of 4 cm and a horizontal diameter of 5 cm.

[0018] As further improvement, the adjustable type fixed clamp includes a connecting rod and an arc-shaped elastic clamp connected to the end of the connecting rod, and the two arc-shaped elastic clamps are coaxial with the inverted cone sputum suction tube.

[0019] As further improvement, the adjustable type fixed clamp is L-shaped or arc-shaped or linear, the height of the adjustable type fixed clamp is limited to control the distance between the mask and the skin of the neck to be 0.8-1.5 cm, and the thickness of the arc-shaped elastic clamp is 0.5-1 mm.

[0020] As further improvement, the arc-shaped elastic clamp is greater than or equal to two-thirds of the circular clamp.

[0021] The beneficial effects of this utility model are as follows:

[0022] The lower opening of the main body of this utility model mask is elliptical, with a vertical diameter of approximately 4cm and a horizontal diameter of approximately 5cm. The mask is adjusted to this size for tracheotomy patients. The flat oval shape can fit the neck width of most tracheotomy patients, thus protecting the skin of the jaw and upper chest from pressure injuries when used by patients with short necks.

[0023] This invention features an adjustable, arc-shaped elastic clamp below the face mask, which secures the tracheostomy tube to the neck with a fixing strap after tracheostomy. The clamp possesses a certain degree of rigidity and toughness, is 0.5-1mm thick, and is fixed above the dressing around the tracheostomy tube, preventing pressure damage to the skin and preventing displacement or slippage.

[0024] The structure of this utility model, in which the mask body and the rotating oxygen supply device are connected in a 360-degree rotation, eliminates the need for patients to adjust the mask angle when changing positions. Simply rotating the mask to connect it to the oxygen tubing can meet the needs of any positional change.

[0025] This utility model features a resealable opening at the top of the mask, with an opening diameter of approximately 5mm, allowing common suction catheters (diameter less than 4mm) to pass smoothly. The axis of the opening is aligned with the axes of the two fixing clips, ensuring coaxiality with the tracheostomy cannula after fixation, allowing the suction catheter to smoothly enter the tracheostomy cannula for suctioning. The opening is inverted conical in shape, with a minimum opening diameter of 5mm, facilitating catheter guidance. The mask does not need to be removed during suctioning, reducing the risk of hypoxemia. Furthermore, the small gap around the suction catheter entrance of the mask reduces droplet splashing, lowering the risk of occupational exposure to mucous membranes and cross-infection for medical personnel. The opening can be sealed after suctioning.

[0026] This utility model features an adjustable fixing clip with a height of approximately 1 cm, allowing the patient's exhaled air to be smoothly discharged through the gaps around the mask. This ensures that carbon dioxide is fully expelled when the patient is receiving adequate oxygen, preventing backflow that could lead to respiratory acidosis. Furthermore, its height facilitates cleaning when droplets flow down after suctioning.

[0027] This utility model mask has a maximum diameter of 5cm and an adjustable fixing clip height of about 1cm. It can effectively cope with the spray of droplets at an angle of 0-60 degrees or more to the axis after passing through the tracheostomy tube. While providing sufficient protection area, it reduces the feeling of a foreign body in the neck and improves patient comfort.

[0028] The oxygen inhalation tube connector of this invention is threaded to the oxygen inhalation tube, making it less prone to slippage after connection. Its opening is inside the rotatable oxygen supply device, forming an annular airflow for oxygen supply inside the mask. Attached Figure Description
