Description

Technical Field

[0001] The utility model belongs to the technical field of medical implant catheters, and particularly relates to a tracheotomy catheter. Background Art

[0002] In the intensive care unit (ICU), there are often patients who have laryngeal dyspnea, abnormal respiratory function, or dyspnea caused by retention of lower respiratory tract secretions for various reasons. Tracheotomy treatment is required, and a tracheotomy catheter is indwelled to establish an artificial airway, which can help the patient maintain respiration, keep the respiratory tract unobstructed, and ensure the stability of vital signs. During the clinical application of the tracheotomy catheter, an airbag is often set to effectively intercept upper respiratory tract secretions such as the oropharynx and produce a certain fixed pressure and limiting effect. However, for a tracheotomy catheter indwelled for a long time, the fixed position of the airbag on the tracheal wall forms long-term compression, which may lead to impaired blood circulation in the tracheal mucosa, local ulceration, ischemic necrosis or perforation, and even erosion of the esophagus, ultimately resulting in the serious consequence of tracheoesophageal fistula.

[0003] In the prior art, the patent document with the publication number CN 202446619 U discloses a tracheotomy double-airbag catheter, belonging to the field of medical supplies, including a tracheal catheter and an airbag located on the outer wall of the tracheal catheter. The airbag is connected to an inflation valve. Its characteristics are that the airbag is divided into an upper airbag and a lower airbag. The upper airbag is connected to the upper inflation valve through an upper inflation channel, and the lower airbag is connected to the lower inflation valve through a lower inflation channel.

[0004] In addition, the patent document with the publication number CN 219835991 U discloses a double-airbag tracheotomy catheter, which includes a tracheotomy catheter main body, a first airbag, a second airbag, a first inflation tube communicating with the first airbag, a second inflation tube communicating with the second airbag, a suction tube, and a fixing wing.

[0005] The above two solutions both adopt the method of alternating the use of double airbags to solve the problem of serious adverse consequences such as ulcers caused by long-term compression of the fixed position of the airbag on the airway mucosa. However, when the length of the incision catheter is too short, or when the setting space is insufficient due to other components, it is difficult to implement the solution of setting double airbags. Moreover, when the surface of the airbag used previously has a certain adhesion to the tracheal wall during the alternating use of the double airbags, it cannot well play the role of avoiding serious adverse consequences such as tracheal ulcers. And due to the different setting positions of the double airbags, it is not conducive to completely extracting and discharging upper respiratory tract secretions. Content of the Utility Model

[0006] I. Technical Problems to be Solved

[0007] In view of the deficiencies of the prior art, the present utility model provides a tracheotomy catheter with a simple structure, which can prevent the airbag of a long-term indwelling tracheotomy catheter from causing long-term compression on the fixed position of the tracheal wall, and avoid adhesion between the surface of the airbag and the tracheal wall, thereby completely preventing clinical problems such as tracheal mucosa blood circulation disorder, local ulceration, ischemic necrosis or perforation, and even erosion of the esophagus, and is conducive to completely extracting and discharging upper respiratory tract secretions.

[0027] Embodiment:

[0028] As Figure 1 、 Figure 2 and Figure 3 shown: A tracheotomy catheter is provided with a fixing wing 1 and a catheter body 2. The fixing wing 1 is arranged at the outer end of the catheter body 2. A movable mounting sleeve 3 is movably sleeved at the inner end of the catheter body 2. An airbag structure 4 is arranged on the movable mounting sleeve 3. A telescopic secretion suction nozzle structure 5 and a moving control device 6 are connected to the upper side of the movable mounting sleeve 3. The airbag structure 4 is also connected to an inflation device 8 through an inflation tube structure 7. The telescopic secretion suction nozzle structure 5, the moving control device 6 and the inflation tube structure 7 all pass through the fixing wing 1 along the outer wall of the catheter body 2.

[0029] A movable limit annular groove part 21 is arranged at the inner end of the catheter body 2. The movable mounting sleeve 3 is movably sleeved on the movable limit annular groove part 21, and the movable limit annular groove part 21 plays a role in limiting the movement of the movable mounting sleeve 3.

[0030] Among them, the retractable secretion suction nozzle structure 5 includes a fixed pipe 51, a telescopic sleeve 52 and a suction joint 54. The fixed pipe 51 is fixedly arranged on the outer wall of the catheter body 2, and the fixed pipe 51 is arranged between the moving limit annular groove part 21 and the fixed wing 1. One end outer wall of the telescopic sleeve 52 is slidably matched with the inner wall of the fixed pipe 51, and the suction joint 54 is connected to the fixed pipe 51 through a hose; the other end of the telescopic sleeve 52 is connected to the moving mounting sleeve 3, and a suction opening is also provided at the other end of the telescopic sleeve 52, and the suction opening is arranged close to the moving mounting sleeve 3. Among them, the fixed pipe 51 is integrally formed with the outer wall of the catheter body 2, and a leak-proof sealing ring is provided between the outer wall of the telescopic sleeve 52 and the inner wall of the fixed pipe 51.

[0031] The above-mentioned moving control device 6 includes two cable structures 61 and a pull ring 62. The pull ring 62 is connected to the outer end of the cable structure 61. The inner ends of the two cable structures 61 respectively pass through the opposite channels on the outer wall of the catheter body 2 and are connected to both sides of the moving mounting sleeve 3, and pulling the moving mounting sleeve 3 symmetrically on both sides is more stable.

[0032] Furthermore, the moving control device 6 includes two cable structures 61 and a pull ring 62. The pull ring 62 is connected to the outer end of the cable structure 61. The retractable secretion suction nozzle structure 5 includes two fixed pipes 51 and two telescopic sleeves 52. The two fixed pipes 51 are arranged on two opposite side walls of the catheter body 2. The inner ends of the two cable structures 61 respectively pass through the two fixed pipes 51 and are connected to the two telescopic sleeves 52. This avoids arranging another channel on the outer wall of the catheter body 2, and indirectly pulling the moving mounting sleeve 3 symmetrically on both sides through the telescopic sleeves 52 is more stable, and avoids the jamming of the telescopic sleeves 52 during telescoping.

[0033] Still further, the inflation device 8 is an inflation balloon or an indicating balloon. The balloon structure 4 includes an annular inner balloon 41 and an offset outer balloon 42. The annular inner balloon 41 is arranged around the moving mounting sleeve 3. The offset outer balloon 42 is arranged on one side of the annular inner balloon 41 and smoothly transitions. The annular inner balloon 41 and the offset outer balloon 42 are respectively connected to different inflation devices 8 through different inflation pipe structures 7. This is convenient for independent control. The setting of the offset outer balloon 42 is used to push open the inner port of the catheter body 2 against the bending direction and separate it from the tracheal wall when the inner port of the catheter body 2 is bent and blocked by the tracheal wall, so as to avoid the blockage of the artificial airway formed by the catheter body 2. And the connection of the inflation pipe structure 7 and the inflation device 8 for inflation and deflation is a conventional setting method, and other settings such as deflation valves and one-way valves will not be elaborated here.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims.
