Description

Modified tracheal tube assembly

technical field

The utility model belongs to the technical field of medical treatment, in particular to an improved tracheal sleeve assembly.

Background technique

Tracheotomy, referred to as "tracheotomy", is a transverse incision between the tracheal cartilage to establish an artificial airway and allow patients to breathe through a new channel. It is a clinical treatment and rescue of critically ill patients due to various An important first aid technique for airway obstruction caused by the cause. As an invasive artificial airway, its respiratory care directly affects the effect of rescue and treatment. After the artificial airway is established, since the gas avoids the humidification function of the nose and mouth, the humidification of the airway itself is significantly reduced or even disappeared after tracheotomy, causing the lumen secretions to stick, block the lumen, and affect the normal airway. Respiratory function, but also easily lead to bacterial invasion. Adequate humidification of the airway is one of the keys to keeping the airway open after tracheotomy and preventing pulmonary infection. At present, the humidification tube is often fixed in the tracheal cannula in clinical practice, but the humidification tube or oxygen tube is prolapsed due to the patient's coughing, etc., which affects the humidification effect, and also easily causes the patient's lung infection and even threatens the patient's life. Safety. In the existing humidification scheme, the liquid injection is too fast or the liquid droplets are too large to stimulate the airway, which is easy to cause the patient to cough; for patients with lung infection, a large amount of sputum will be excreted due to coughing, and there is no sputum-containing device. Temporary collectors can easily contaminate the sterile square gauze pads under the tracheal tube and the patient's clothing and bed sheets with the coughed up sputum, which increases the workload of medical staff to replace these items, and also increases the risk of infection.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides an improved tracheal cannula assembly which is convenient for airway humidification and has the function of collecting sputum.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: an improved tracheal sleeve assembly, including an outer sleeve, an inner sleeve and an inner core rod, the front end of the inner sleeve is fixed with a short sleeve, and the outer wall of the short sleeve is a double-layered Structure, a humidification storage cavity is formed in the wall of the short sleeve, a humidification interface is connected to the short sleeve, and a number of mutually independent humidification channels are opened in the pipe wall of the inner sleeve along its length direction, and several humidification channels are connected with each other. The humidification reservoir is communicated.

The rear end of the humidification channel is connected with a fence grid.

The front end of the short sleeve is connected with a sputum collection component, and the front end of the short sleeve is connected with a first external thread interface. The sputum collection component includes a breathable sleeve, a guide elbow and a sputum collection bottle. The breathable sleeve and the guide elbow are integrally formed and ventilated. The sleeve is threadedly connected to the first external thread interface, the ventilating sleeve is evenly distributed with several air holes, the lower part of the guide elbow is connected with a second external thread interface, and the sputum collection bottle is threadedly connected to the second external thread interface.

The first external thread interface is provided with an oxygen pipe jack.

By adopting the above technical scheme, the utility model has the following beneficial effects: in order to reduce the stimulation of the patient's airway caused by the excessively fast inflow of the humidified liquid, a plurality of humidification channels are arranged in the tube wall of the inner cannula, so as to prevent the humidification of the patient's airway. The liquid is shunted, and after shunting, the humidified liquid is dispersed into multiple branches, which slows down the overall humidification liquid injection speed; in addition, a sputum collection component is provided to facilitate the temporary collection of patient sputum; the overall structural design is reasonable and easy to use.

Detailed ways

As shown in Figures 1-4, the improved tracheal sleeve assembly of the present invention includes an outer sleeve, an inner sleeve 1 and an inner core rod. The outer sleeve and the inner core rod are in the prior art, not shown in the figures. Tethers are connected on both sides of the tube, which is convenient to fix it on the patient's neck. The front end of the inner cannula 1 is fixed with a short sleeve 2. The outer wall of the short sleeve 2 is a double-layer structure, and a humidification storage cavity is formed in the wall of the short sleeve 2. 3. A humidification interface 4 is connected to the short sleeve 2, and a number of mutually independent humidification channels 5 are opened in the pipe wall of the inner sleeve 1 along its length direction, and several humidification channels 5 are connected with the humidification storage cavity 3. Pass.

The rear end of the humidification channel 5 is connected with a fence grid 6 .

The front end of the short sleeve 2 is connected with a sputum collection assembly, the front end of the short sleeve 2 is connected with a first external thread interface 7, and the sputum collection assembly includes a breathable sleeve 8, a guide elbow 9 and a sputum collection bottle 10, the breathable sleeve 8 and the sputum collection bottle 10. The guide elbow 9 is integrally formed, the ventilation sleeve 8 is threadedly connected to the first external thread interface 7, the ventilation sleeve 8 is evenly distributed with a number of ventilation holes 11, and the lower part of the guide elbow 9 is connected with a second external thread interface 12.
