Abstract
The utility model discloses a tracheal catheter having a pressure regulating function. The tracheal catheter comprises an air guide tube, a side air guide port arranged in a side wall of a lower tube opening of the air guide tube and air bags which the air guide tube is fixedly sleeved with. The air bags are a first air bag and a second air bag, wherein the air guide tube is fixedly sleeved with the first air bag and the second air bag in the axial direction at intervals from top to bottom. The two air bags are respectively communicated with lower ports of two inflation tubes arranged in an air guide tube interlayer, upper ports of the two inflation tubes extend out of the air guide tube in a sealed mode through the position of a tube wall of the upper portion of the air guide tube, and tube walls of the two inflation tubes extending out of the air guide tube are respectively provided with a branch tube with a pressure regulating air escape valve. The tracheal catheter has the advantages of being simple in structure and convenient to operate. The contact surfaces between the cylindrical air bags and a human body tracheal wall are wide, stress is uniform, and the goal of adjusting air bag inflation pressure is achieved through the pressure regulating air escape valves. The two air bags are inflated alternately so that the position of the stressed tracheal wall is changed without moving the tracheal catheter, and the damage to the patient's tracheal wall caused by the fact that the local tracheal wall is stressed for a long time is avoided.
Description
Technical field
This utility model relates to a kind of medical endotracheal tube, especially relates to the endotracheal tube with voltage regulation function.
Background technology
Endotracheal tube is to keep the unobstructed necessary medical instruments of patient's upper respiratory tract in the processes such as first aid cardio-pulmonary resuscitation, mechanical ventilation general anesthesia and Failure Treated with Mechanical Ventilation.The air bag being sleeved on endotracheal tube is the necessary device that prevents endotracheal tube gas leakage.At present conventional endotracheal tube is generally with single air bag, the sensation that pressure after airbag aeration size is pushed outer aerating gasbag pressure with medical worker conventionally judges by personal experience, if gasbag pressure is too low, can leak gas, and hypertonia will be damaged patient's tracheal wall, cause ischemia downright bad, the serious complication such as tracheo esophageal fistula, tracheal stenosis that even cause.
Summary of the invention
This utility model object is to provide a kind of endotracheal tube with voltage regulation function.
For achieving the above object, this utility model is taked following technical proposals:
The endotracheal tube with voltage regulation function described in the utility model, comprises airway, is opened in the side air guide port on described airway lower nozzle sidewall, and is fixedly set in the air bag on airway; Described air bag is the first air bag and the second air bag along the fixing suit in the axial interval from top to bottom of airway, described the first air bag is connected with the lower port of the first gas tube in being arranged on airway interlayer, described the second air bag is connected with the lower port of the second gas tube in being arranged on airway interlayer, and the tube wall place sealing of the upper port self-conductance upper tracheal of described the first gas tube and the second gas tube is extended outside airway; On the described tube wall that extends the first gas tube outside airway, be provided with the first arm with the first adjust blood pressure air escape valve, on the described tube wall that extends the second gas tube outside airway, be provided with the second arm with the second adjust blood pressure air escape valve.
Described the first air bag and the second air bag are cylindrical structural.
This utility model advantage is simple in structure, easy to operate, and the gasbag pressure having solved on existing endotracheal tube is felt the deficiency of judgement with medical worker.Meanwhile, cylindrical air bag and person's windpipe wall contact surface is extensive, pressurized is even, when cylindrical air bag internal gas pressure is too high, can reach fine adjustment air bag inflation pressure object by accurate voltage regulating air escape valve.During use, two cylindrical air bags are alternately inflated the position that can realize not mobile endotracheal tube and change pressurized tracheal wall, have avoided the long-time pressurized of local tracheal wall to cause patient's tracheal wall impaired.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the endotracheal tube with voltage regulation function described in the utility model, comprises airway 1, is opened in the side air guide port 3 on airway 1 lower nozzle 2 sidewalls, and is fixedly set in the air bag on airway 1; For realizing not mobile endotracheal tube, change the position of pressurized tracheal wall, air bag is the first air bag 4 and the second air bag 5 along the cylindrical structural of the fixing suit in the axial interval from top to bottom of airway 1, the first air bag 4 is connected with the lower port of the first gas tube 6 in being arranged on airway 1 interlayer, the second air bag 5 is connected with the lower port of the second gas tube 7 in being arranged on airway 1 interlayer, and the upper port of the first gas tube 6 and the second gas tube 7 is extended outside airway 1 from the sealing of the tube wall place on airway 1 top; On the tube wall that extends the first gas tube 6 outside airway 1, be provided with the first arm 10 with the first adjust blood pressure air escape valve 8 of precision, on the tube wall that extends the second gas tube 7 outside airway 1, be provided with the second arm 11 with the second adjust blood pressure air escape valve 9 of precision.
