[0032] The following further elaborates on the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for ease of description, only the parts related to the utility model are shown in the drawings.

[0033] As Figures 1-4 shown, a tracheal catheter for the respiratory department of the present utility model includes a tube body 1 and further includes:

[0034] a humidifying mechanism 3 and an exhaust assembly 2; wherein:

[0035] The humidifying mechanism 3 includes a water storage tank 31 fixedly connected to the tube body 1. The water storage tank 31 can effectively increase the humidity of the gas and improve the comfort of the patient. The top of the water storage tank 31 is provided with an intake groove a 36 and an outlet groove a 38. Inside the water storage tank 31, there is a water blocking plate 32. The water blocking plate 32 is provided with a ventilation hole 33 and an intake groove b 37. The diameter range of the ventilation hole 33 is 0.2 - 0.5 mm. The outer wall of the water storage tank 31 is provided with a liquid level glass 35 and a water injection hole 34. The liquid level glass 35 facilitates real-time monitoring of the water level, and the water injection hole 34 provides a more convenient and rapid water replenishment operation.

[0036] The exhaust assembly 2 includes a connector 22 with one end connected to the pipe body 1, an outer shell 21 covering the middle part, an air leakage hole 25 provided on the side of the outer shell 21 close to the pipe body 1, a duckbill plate 23 provided in the middle of the outer shell 21. The duckbill plate 23 only allows gas to enter the trachea from the airbag 5, playing a role in preventing gas backflow. A baffle 26 is movably installed on the periphery. The baffle 26 can completely block the air leakage hole 25. One side of the baffle 26 is closely attached to the inner layer of the outer shell 21 on the side where the air leakage hole 25 is provided, and a spring 27 is fixedly installed on the other side. The spring 27 ensures that the baffle 26 is always in a position close to the inner layer of the outer shell 21 on the side where the air leakage hole 25 is provided. The other end of the spring 27 is fixedly installed on the other side of the inner layer of the outer shell 21. The exhaust assembly 2 can make the exhaled gas emit from the air leakage hole 25 and also ensure the stability of the air pressure inside the catheter.

[0037] As Figure 1 shown, in this embodiment, a balloon 4 is provided at one end of the pipe body 1. After the pipe body 1 is inserted into the human trachea, the balloon 4 is inflated to establish a closed space, which can not only prevent the catheter from shifting during use but also ensure the effect of gas delivery. The balloon 4 is provided with an inflation tube 9. The middle part of the inflation tube 9 is buried inside the wall of the pipe body 1, which can reduce the discomfort when the pipe body 1 is inserted into the human trachea. The other end extends out on the left side of the exhaust assembly 2 to ensure the independence of the inflation and exhaust functions.

[0038] As Figure 1 shown, in this embodiment, the pipe body 1 further includes an airbag 5 fixedly connected to the other end. The airbag 5 is used for gas delivery. A one-way valve 6 is provided at one end of the airbag 5 to ensure that gas can only enter the airbag 5 in one direction. The other end is fixedly connected to an intake pipe 11 to ensure the stability of gas delivery.

[0039] As Figure 1 shown, in this embodiment, a pressure valve 7 is fixedly installed on the pipe body 1 on the right side of the exhaust assembly 2. The upper pressure limit of the pressure valve 7 is 40 cmH2O to ensure that the air pressure inside the catheter is always within a safe range and prevent safety problems caused by excessive air pressure. A heating sheet 8 is covered on the pipe body 1 on the right side of the pressure valve 7. The heating sheet 8 can heat the gas, and its temperature range is 37 - 38 °C to ensure that the temperature of the gas passing through the pipe body 1 is within a suitable range and improve the comfort of the patient. The other end of the pipe body 1 is connected to an outlet pipe 12.

[0040] As Figure 2 shown, in this embodiment, the other end of the outlet pipe 12 extends into the air outlet groove a38 and is fixedly connected to a water storage chamber 31. The position where the outlet pipe 12 extends is above the horizontal height of the water blocking plate 32. The other end of the intake pipe 11 extends into the air intake groove a36 and the air intake groove b37 to the bottom of the water storage tank and is fixedly connected to the water storage chamber 31 to ensure that the gas can fully pass through the water storage tank for humidification. The fixed connection ensures airtightness and prevents gas leakage.

[0041] AsFigure 2 As shown, in this embodiment, the water injection hole 34 is provided in the middle of the water storage chamber 31, below the horizontal height of the water blocking plate 32, which can prevent the liquid level from being higher than the height of the water blocking plate 32 during water injection and directly entering the air flow channel, thus affecting the humidification effect.

[0042] As Figure 1 As shown, in this embodiment, the tube body 1, the balloon 4 and the duckbill plate 23 are all made of medical-grade silicone material, ensuring that the tube body 1 will not cause allergic reactions when in contact with the human body and has good sealing performance.

[0043] The working principle and usage process of this technical solution are as follows: First, inject an appropriate amount of water into the water storage chamber 31 through the water injection hole 34. Insert the end of the tube body 1 with the balloon 4 into the trachea of the patient. Inflate the balloon 4 through the inflation tube 9 to fix the catheter in place. Press the airbag 5, and the gas passes through the intake pipe 11, the intake groove a36, and the intake groove b37 into the water storage chamber 31 for humidification treatment, and then enters the outlet pipe 12 through the ventilation hole 33 and the outlet groove a38. The heating sheet 8 heats the gas passing through the tube body 1 to ensure that the gas temperature is within the range of 37-38°C. Then, the pressure valve 7 adjusts the air pressure in the trachea to ensure that the upper pressure limit is 40 cmH2O. The gas further enters the human body through the duckbill plate 23 and into the tube body 1. During exhaust, the gas pushes open the baffle 26 through the air release groove 24 and is discharged through the air release hole 25.

[0044] The above combines embodiments to further describe the present invention, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
