Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation medicine, in particular to an improved tracheotomy cannula which can prevent airbag from ascending wrinkles and can perform deep subglottic suction. Background Art

[0002] When patients suffer from respiratory failure, difficulty in coughing up sputum, and spontaneous breathing cannot meet the body's ventilation and oxygen supply, they are usually given a tracheotomy and a tracheostomy tube is inserted. Many critically ill patients require a tracheotomy and a disposable tracheostomy tube is placed for a long time. The insertion process is smooth, but when the tracheal tube needs to be removed, the following injuries may occur: secondary injury caused by ascending wrinkles. The spherical balloon wrapped outside increases the diameter of the tracheostomy tube, making the tracheostomy wound small and difficult to remove; wrinkles are easily formed after the gas in the balloon is exhausted, especially the upward wrinkles formed on the upper end of the balloon. The balloon becomes tougher as the catheter is placed for a longer time. During the process of tube removal, the upward wrinkles will get stuck in the tracheotomy wound of the neck and be difficult to remove, resulting in failure of tube removal. Violent removal will cause bleeding from the tracheotomy wound, prolonged bleeding, infection, and secondary injury. Aspiration will cause secondary injury. The secretions accumulated in the trachea from below the glottis to the tracheal tube balloon are difficult to directly aspirate. The inflated state of the balloon can prevent the secretions from seeping downward, but the secretions will be accidentally inhaled into the deep trachea or even the bronchi when the balloon is deflated, causing lung infection, atelectasis, bronchial obstruction, etc.

[0003] The existing tracheostomy cannula with suction on the air bag has a limited suction range, and the fixed side hole on the bag is difficult to completely suction all the secretions. After the tracheotomy is removed, it will cause lung infection and secondary injury. Therefore, we propose an improved tracheostomy cannula that can prevent the air bag from wrinkling upward and can perform deep subglottic suction. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the utility model provides an improved tracheostomy tube which can prevent upward wrinkles of the air bag and can perform deep subglottic suction, thereby solving the problems of upward wrinkles caused by the evacuation of the air bag when the user removes the tracheostomy tube, resulting in extubation failure, bleeding or even infection, and aspiration pneumonia after extubation caused by downward aspiration of secretions on the air bag.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an improved tracheostomy cannula that can prevent airbag upward wrinkles and can perform deep subglottic suction, comprising a tracheostomy cannula main body, a tracheal tube joint fixedly installed on the upper end of the tracheostomy cannula main body, a balloon connected to the bottom of the tracheostomy cannula main body, catheter buckles installed on the left and right sides of the tracheal tube joint, an inflation channel and two suction channels are respectively opened inside the tracheostomy cannula main body, an inflation channel is connected to the upper end of the inflation channel, suction tubes are sleeved inside the two suction channels, two tube sealing clamps are movably installed on the top of the two suction tubes, an inflation joint is installed at one end of the inflation tube, an inverted umbrella-shaped plastic frame is arranged inside the balloon, a handle is fixedly installed on the top of the inverted umbrella-shaped plastic frame, a lifting handle is provided on the top of the handle, two suction holes are opened on the top of the balloon, and an inflation hole is connected to one end of the inflation tube.

[0006] Preferably, the lower end of the inflation channel is communicated with the inflation hole, and the upper end of the inflation channel is connected to the inflation tube.

[0007] Preferably, the two suction tubes are sleeved inside the two suction channels.

[0008] Preferably, the balloon is in the shape of an inverted funnel, and the balloon is connected to the bottom of the tracheostomy tube body.

[0009] Preferably, the two tube sealing clamps are installed on the tops of the two suction tubes.

[0010] Preferably, the top of the inverted umbrella-shaped plastic frame is fixedly connected to the handle, and the other end of the inverted umbrella-shaped plastic frame is connected to the inner wall of the balloon.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model has two suction channels, and can effectively suction the patient in supine, left-side or right-side lying positions. A movable suction tube is added to the two suction channels, and the suction tube moves up and down in the suction channel and passes through the suction hole, so as to fully suction the subglottic secretions.

[0013] On the one hand, the utility model reduces balloon wrinkles by designing a funnel-shaped balloon and reducing the area of ​​the upper end of the balloon; on the other hand, the lifting handle is linked to the lifting handle, and the two lifting handles are connected to an inverted umbrella-shaped plastic frame. When the inverted umbrella-shaped plastic frame is lifted, the inverted umbrella-shaped plastic frame will be folded and pull the upper end of the balloon downward, thereby avoiding the formation of upward wrinkles when the balloon is deflated, thereby avoiding secondary damage to the patient.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides an improved tracheostomy cannula which can prevent airbag ascending wrinkles and can perform deep subglottic suction, comprising a tracheostomy cannula body 1, a tracheal tube connector 2 is fixedly installed on the upper end of the tracheostomy cannula body 1, a balloon 3 is connected to the bottom of the tracheostomy cannula body 1, and catheter buckles 4 are installed on the left and right sides of the tracheal tube connector 2, an inflation channel 12 and two suction channels 13 are respectively opened inside the tracheostomy cannula body 1, an inflation channel 8 is connected to the upper end of the inflation channel 12, a suction tube 11 is sleeved inside the two suction channels 13, two tube sealing clamps 10 are movably installed on the top of the two suction tubes 11, an inflation connector 9 is installed at one end of the inflation tube 8, an inverted umbrella-shaped plastic frame 6 is arranged inside the balloon 3, a handle 7 is fixedly installed on the top of the inverted umbrella-shaped plastic frame 6, a lifting handle 5 is provided on the top of the handle 7, a suction hole 15 is opened on the top of the balloon 3, and an inflation hole 14 is connected to one end of the inflation tube 8.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the lower end of the inflation channel 12 is communicated with the inflation hole 14 , and the upper end of the inflation channel 12 is connected to the inflation tube 8 .

[0023] The above scheme is adopted: by inflating the inside of the inflation connector 9, the gas inflates the balloon 3 through the inflation connector 9, the inflation tube 8, the inflation channel 12 and the inflation hole 14, so that the balloon 3 is connected to the inner wall of the patient's trachea and thus closes the patient's airway.

[0024] like Figure 2 and Figure 5 As shown, the two suction tubes 11 are respectively sleeved inside the two suction channels 13 , and the two tube sealing clamps 10 are installed on the tops of the two suction tubes 11 .

[0025] The above scheme is adopted: the balloon 3 is in the shape of an inverted funnel. When the patient has secretions, they will accumulate in the direction of the lower airway along the inverted funnel-shaped balloon 3. By loosening the two tube sealing clamps 10 respectively, the two suction tubes 11 can be pushed downward along the two suction channels 13 until the suction tubes 11 pass through the suction hole 15, thereby clearing the subglottic secretions and preventing the patient from aspiration.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the balloon 3 is in the shape of an inverted funnel, the balloon 3 is connected to the bottom of the tracheostomy tube body 1, the top of the inverted umbrella-shaped plastic skeleton 6 is fixedly connected to the handle 7, the top of the handle 7 is the pulling handle 5, and the other end (end) of the inverted umbrella-shaped plastic skeleton 6 is connected to the upper end of the balloon 3.

[0027] The above scheme is adopted: when the tracheal tube needs to be removed, on the one hand, the balloon 3 is in the shape of an inverted funnel, and its special inverted funnel-shaped design itself can reduce the area of ​​the upper end of the balloon and reduce the possibility of wrinkle formation; on the other hand, the syringe is connected to the inflation connector 9 to slowly draw air, and at the same time, the handle 7 and the lifting handle 5 are pulled upward, so that the inverted umbrella-shaped plastic frame 6 is pulled downward. Since the inverted umbrella-shaped plastic frame 6 is connected to the upper end of the balloon 3, the upper end of the balloon 3 is pulled downward, thereby avoiding the formation of upward wrinkles on the upper end of the balloon 3.

[0028] The working principle and use process of this utility model:

[0029] When using the improved tracheostomy cannula body 1, the gas inflates the balloon 3 through the inflation connector 9, the inflation tube 8, and the inflation channel 12. The balloon 3 is close to the inner wall of the patient's trachea and then the airway is closed; when removing the improved tracheostomy cannula body 1, first loosen the two tube sealing clamps 10, and the suction tube 11 attracts the subglottic secretions. Then, the suction tube 11 is pushed downward along the suction channel 13 and the suction hole 15. The suction tube 11 passes through the suction hole 15 to clear the subglottic secretions and avoid accidental aspiration. The inflation connector 9 slowly draws air, and the lifting handle 7 and the lifting handle 5 are pulled upward to pull the inverted umbrella-shaped plastic frame 6 downward. Since the inverted umbrella-shaped plastic frame 6 is connected to the upper end of the balloon 3, the upper end of the balloon 3 is pulled downward, thereby avoiding the formation of wrinkles at the upper end of the balloon 3.
