DETAILED DESCRIPTION

[0023] 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 of 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.

[0024] See also Figure 1-Figure 3 As shown, the utility model is a tracheotomy catheter, comprising a tracheotomy catheter 1, the tracheotomy catheter 1 is a curved structure, and a gas delivery terminal 103 is provided at the end of the tracheotomy catheter 1;

[0025] In one implementation of this embodiment, a cuff 102 is provided at one end of the gas delivery end 103 close to the tracheotomy tube 1, the cuff 102 is wrapped around the tracheotomy tube 1, and the cuff 102 is connected to an inflation device; specifically, when the tracheotomy tube 1 is used, the cuff 102 is inflated by the inflation device to expand the cuff 102, so as to position the tracheotomy tube 1 and make it more stable when used;

[0026] The end of the tracheostomy catheter 1 away from the gas supply end 103 is connected to a telescopic hose 3, and the end of the telescopic hose 3 is provided with a connecting end 301, and the connecting end 301 is connected to the oxygen supply tube; it can be explained that in this embodiment, by providing the telescopic hose 3 at the end of the tracheostomy catheter 1, the telescopic hose 3 can not only be bent to any angle, but also can be freely extended and retracted, so there is no need to connect a longer pipe to the end of the tracheostomy catheter 1, thereby avoiding the phenomenon of bending, and effectively improving stability and safety.

[0027] Example 2

[0028] Based on Example 1, please refer to Figure 1-Figure 3 A fixing wing 101 is also provided between the telescopic hose 3 and the tracheotomy tube 1 to position the tracheotomy tube 1; specifically, by providing the fixing wing 101, the tracheotomy tube 1 has a higher stability during positioning;

[0029] As a further solution of this embodiment, a first strap 202 is provided at one end of the fixed wing 101, and a second strap 203 is provided at the other end of the fixed wing 101, and the first strap 202 and the second strap 203 are bonded by Velcro; it can be explained that in order to further improve the stability of the fixation of the tracheostomy tube 1, this embodiment provides the first strap 202 and the second strap 203. In actual application, the first strap 202 and the second strap 203 are wrapped around the back of the patient's neck, and then fixed by Velcro, thereby improving its stability during positioning.

[0030] Specifically, the first strap 202 and the second strap 203 are both fixed to the fixing wing 101 through the positioning plate 2 and the positioning bolt 201; it can be explained that the fixing method through the positioning bolt 201 facilitates the disassembly and assembly of the first strap 202 and the second strap 203, and they can be directly disassembled when not in use.

[0031] The inflation device includes an air supply pipe 303 connected to the cuff 102, the other end of the air supply pipe 303 is connected to the inflation bag 304, and an air inlet pipe 305 is arranged at the other end of the inflation bag 304, wherein a one-way valve limited to air intake is arranged between the air inlet pipe 305 and the inflation bag 304, and a one-way valve limited to air exhaust is arranged between the air supply pipe 303 and the inflation bag 304; it can be explained that when inflating the cuff 102, the medical staff presses the inflation bag 304 back and forth, and the inflation bag 304 inputs external air through the air inlet pipe 305 and then transports it to the cuff 102 through the air supply pipe 303, thereby achieving the inflation effect, and the operation is convenient.

[0032] Furthermore, a thread 302 is provided in the connecting end 301 for connecting to the end of the oxygen supply tube, an annular groove 306 is provided in the end of the connecting end 301 away from the telescopic hose 3, an annular sealing airbag 307 is embedded in the annular groove 306, an annular airbag 308 is provided in the end of the connecting end 301 close to the telescopic hose 3, and the annular airbag 308 is connected to the sealing airbag 307 through an airway 309 provided in the connecting end 301; specifically, when the end of the oxygen supply tube is spirally installed on the connecting end 301, the annular airbag 308 is squeezed so that the gas in the annular airbag 308 enters the sealing airbag 307 through the airway 309, so that the sealing airbag 307 expands, thereby increasing the tightness of the connection with the end of the oxygen supply tube, improving the sealing performance, and avoiding leakage.

[0033] The working principle of the utility model is as follows: by arranging a telescopic hose 3 at the end of the tracheotomy catheter 1, the telescopic hose 3 can not only be bent to any angle, but also be freely retractable. When inflating the cuff 102, the medical staff presses the inflation bag 304 back and forth, and the inflation bag 304 inputs external air through the air inlet pipe 305 and then transmits it to the cuff 102 through the air supply pipe 303, thereby achieving the inflation effect. When the end of the oxygen supply tube is spirally installed on the connecting end 301, the annular air bag 308 is squeezed so that the gas in the annular air bag 308 enters the sealing air bag 307 through the airway 309, so that the sealing air bag 307 expands, thereby increasing the tightness of the connection with the end of the oxygen supply tube.
