Description

Technical Field

[0001] The utility model relates to the technical field of anti - splashing devices, and particularly relates to an anti - splashing device for tracheal cannulas. Background Art

[0002] Tracheotomy is one of the important measures to relieve upper respiratory tract obstruction and patients with respiratory muscle paralysis. Generally, the situations that require tracheotomy include the following: 1. Laryngeal obstruction, acute and chronic laryngeal obstruction caused by pharyngeal inflammation, tumors, foreign bodies, trauma or cicatricial stenosis, etc., leading to hypoxia and asphyxia; 2. Lower respiratory tract secretion obstruction; 3. Those who need to use a ventilator for assisted breathing for a long time; 4. Prophylactic tracheotomy; 5. Other factors, such as those who need to undergo tracheal intubation anesthesia but cannot be intubated through the mouth and nose, and those who cannot remove foreign bodies in the respiratory tract through the larynx, etc.

[0003] After tracheotomy, tracheal intubation is required. For example, a Chinese patent with the application number: "202120077530.1" and the name: "An anti - sputum splashing device for tracheotomy" includes a splash - proof tank for sleeving on the tracheotomy intubation. The top of the splash - proof tank has a ventilation port. The top of the front end of the inner cavity of the splash - proof tank is made into an inclined surface. A sputum drainage pipe is connected to the side of the splash - proof tank, and the sputum drainage pipe is communicated with the inner cavity of the splash - proof tank. It can collect sputum and other secretions splashed from the tracheotomy intubation of patients after tracheotomy through the setting of the splash - proof tank, prevent the pollution caused by the coughing up of sputum and other secretions in the airway of patients after tracheotomy, and at the same time can discharge the collected sputum.

[0004] However, it is not convenient to atomize the medicine for patients, which limits the functions of use and is not convenient enough to use. Content of the Utility Model

Specific implementation manners

[0022] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0023] Refer to Figures 1-4, an anti - splashing device for a tracheal cannula in an embodiment of the present utility model, which includes a protective cover 103. Strap mounting brackets 102 are provided on both sides of the protective cover 103. Straps 101 are provided on the strap mounting brackets 102. The straps 101 are made of elastic material to ensure the stability of the protective cover 103. The rear part of the protective cover 103 is arc - shaped to fit the patient's neck. A tilted tube 104 is fixedly connected to the front part of the protective cover 103. The inner diameter of the tilted tube 104 is larger than the outer diameter of the cannula, facilitating the accommodation of the cannula. The tilt angle between the tilted tube 104 and the horizontal plane is 15° - 35°, avoiding the backflow of the exhaled liquid. A temporary storage cavity 204 is fixedly connected to the front part of the tilted tube 104. A nebulizing tube 206 is fixedly connected to the left side of the temporary storage cavity 204. A one - way valve 205 is provided on the nebulizing tube 206. A nebulizing cap 207 is threadedly connected to the end of the nebulizing tube 206. A liquid suction tube 203 is fixedly connected to the right side of the temporary storage cavity 204. A control valve 201 is provided on the liquid suction tube 203. A protective cap 202 is threadedly connected to the end of the liquid suction tube 203. A breathing cavity 208 is fixedly connected to the front part of the temporary storage cavity 204. A filter screen 2081 and a protective net 2082 are arranged inside the breathing cavity 208. The filter screen 2081 is located inside the protective net 2082. Both the filter screen 2081 and the protective net 2082 are circular in shape. When in use, after the patient's tracheotomy and cannula installation, this device is placed at the cannula position, enabling the cannula to pass through the tilted tube 104. The protective cover 103 is covered outside the cannula position using the straps 101. The liquid generated during the cannulation process can be sucked out through the liquid suction tube 203. The liquid suction tube 203 can be connected to an external pipeline to ensure that there is no liquid inside the temporary storage cavity 204. The protective cap 202 is used to provide protection for the liquid suction tube 203 when not in use. The control valve 201 is used to control the opening and closing of the liquid suction tube 203. During nebulization, the nebulizing cap 207 is opened, and the nebulizing tube 206 is connected to the pipeline on the nebulizer for nebulization treatment. Then, during normal breathing, gas is exhaled and inhaled through the breathing cavity 208. The filter screen 2081 and the protective net 2082 are used for filtration to ensure that the gas breathed by the patient is relatively clean. By setting the nebulizing tube 206 and the nebulizing cap 207, nebulization operation can be performed on the patient, improving the overall practicality. Moreover, the shape of the protective cover 103 fits better with the tracheotomy site of the patient, increasing the comfort during use. The settings of the breathing cavity 208, the filter screen 2081, and the protective net 2082 increase the cleanliness of breathing, which is beneficial to the patient's recovery.

[0024] Working principle: When in use, after a tracheotomy is performed on the patient and an intubation tube is installed, place this device at the position of the intubation tube, so that the intubation tube passes through the inclined tube 104. Use the strap 101 to cover the protective cover 103 outside the intubation position. The liquid generated during the intubation process can be sucked out through the liquid suction tube 203. The liquid suction tube 203 can be connected to an external pipeline to ensure that there is no liquid inside the temporary storage cavity 204. The protective cover 202 is used to provide protection for the liquid suction tube 203 when not in use. The control valve 201 is used to control the closing and opening of the liquid suction tube 203. During atomization, open the atomization cover 207, connect the atomization tube 206 to the pipeline on the nebulizer, and perform atomization treatment. Then, during normal breathing, gas exhales and inhales from the breathing cavity 208. The filter screen 2081 and the protective net 2082 are used for filtration to ensure that the gas breathed by the patient is relatively clean.

[0025] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can also be made without departing from the gist of the present utility model.
