Description

Artificial airway with real-time monitoring of balloon pressure

technical field

The utility model relates to a medical device, in particular to a tracheal artificial airway.

Background technique

Artificial airways mainly include tracheal intubation and tracheostomy tubes, which are widely used in intensive care medicine, anesthesiology, respiratory, and emergency departments. The main structure of the existing artificial airway is as follows: the front end of a main pipe has an inner air bag, the pipe wall of the main pipe is led into a gas filling tube, the front end of the gas filling tube communicates with the inner air bag, and the rear end of the gas filling tube protrudes It is outside the main pipe and connected with an external air bag. After this kind of artificial airway is placed in the trachea of the human body, the inflatable inner air bag closes the trachea to prevent oropharyngeal secretions from entering the airway by mistake. The inner bladder deflates once and then inflates again. In this kind of artificial airway, there is no setting that can monitor the pressure of the inner air bag in real time. When it is placed or used, it needs to use a pressure monitor to control or detect the air pressure of the inner air bag. In clinical use, it is usually determined by medical staff based on experience. Determine whether the pressure of the inner air bag meets the requirements. The shortcomings of the above-mentioned artificial airway are: in the process of placement or use, repeated use of the pressure monitor is cumbersome to operate, the workload is large, and it takes up more working time; To judge whether the pressure of the inner airbag meets the requirements, once there is an error, it will cause adverse consequences, and serious complications will result.

Utility model content

The purpose of the utility model is to provide an artificial airway that can monitor the pressure of the airbag in real time. When the artificial airway is placed or used, it can be intuitively monitored whether the pressure of the inner airbag meets the requirements without resorting to external equipment.

In order to achieve the above object, the utility model adopts the following scheme: the artificial airway that can monitor the pressure of the air bag in real time has a main pipe, the front end of the main pipe has an inner air bag, and the pipe wall of the main pipe is passed into a gas filling pipe. The front end of the air-filling pipe communicates with the inner air bag, and the rear end of the air-filling pipe protrudes outside the main pipe and connects with an external air bag. A piston cylinder is connected to the external air bag, and a piston and an elastic body are installed in the piston cylinder. The piston will The inner chamber of the piston cylinder is divided into an air intake chamber and an exhaust chamber. The air intake chamber of the piston cylinder communicates with the inner chamber of the external air bag. There is an exhaust hole communicated with the exhaust chamber on the piston cylinder. One side of the piston is connected to the There is an indicating rod, the indicating rod stretches out from the piston cylinder, and the indicating rod is arranged with a scale formed by successively connecting color segments of different colors along the length direction.

It can be seen from the above scheme that since the external airbag communicates with the internal airbag, and the piston cylinder communicates with the external airbag, therefore, when the internal airbag is inflated, the air pressure in the internal airbag will act on the piston in the piston cylinder, and the piston will The air pressure of the body and the inner airbag reaches a balance. When the air pressure in the inner airbag changes, the piston will move. Observe the length of the piston extending out of the cylinder according to the scale on the indicator rod, and you can judge the occurrence of the air pressure in the inner airbag. Whether it meets the requirements after the change, so as to adjust the air pressure in the inner air bag in time.

The utility model has the advantages of simple and reasonable structure, convenient and accurate observation, which can timely remind the medical staff to adjust the air pressure in the inner air bag, and can reduce the monitoring labor of the medical staff.

Detailed ways

Below in conjunction with embodiment and accompanying drawing further illustrate the utility model.

See Figure 1, Figure 2

The artificial airway provided by the utility model which can monitor the pressure of the air bag in real time has a main pipe 1, the front end of the main pipe 1 has an inner air bag 2, and the pipe wall of the main pipe 1 is connected with an air supply pipe 3. The front end of 3 communicates with inner air bag 2, and the rear end of gas-filling pipe 3 stretches out outside main pipe 1, and joins with an external air bag 4, and a piston cylinder 5 is connected on the external air bag 4, and a piston cylinder 5 is housed in the piston cylinder 5. Piston 6 and elastic body, piston 6 divides the inner cavity of piston cylinder 5 into intake cavity 5b and exhaust cavity 5c, the cavity of intake cavity 5b of piston cylinder communicates with the cavity of external air bag 4, has on the piston cylinder 5 An indicator rod 8 is connected to one side of the piston 5 in the exhaust hole 5 a communicating with the exhaust chamber 5 c, and the indicator rod 8 extends out of the piston cylinder 5 . Scales formed by three color segments b, c, and d of different colors are arranged along the length direction on the indicating rod 5 . In this embodiment, the elastic body is the spring 7 . The spring 7 is arranged in the exhaust cavity 5c of the piston cylinder 5, and when the air pressure in the inner airbag 2 acts on the piston 6, the spring 7 is compressed. In addition, the spring 7 can also be arranged in the intake chamber 5b of the piston cylinder 5. When the spring is arranged in the intake chamber, its two ends are respectively connected with the piston cylinder 5 and the piston 6. When the air pressure in the inner airbag 2 acts on the piston When 6 is on, spring 7 is then pulled.

The three different color segments b, c, and d from top to bottom on the indicator rod can be selected as red, green, and white respectively, and the spring is selected according to the following requirements: when the air pressure in the inner air bag 2 acts on the piston 6, the spring 7 is compressed After the elastic deformation, the white color segment d on the indicating rod 8 stretches out of the piston cylinder, or the green segment color segment c and the white color segment d stretch out of the piston cylinder, or the red color segment b, green color segment c and When the white color segments d all extend out of the piston cylinder, it indicates that the air pressure in the inner air bag is low, normal, and high respectively.

It can be seen from Figure 1 and Figure 2 that the artificial airway provided by the utility model can be used as a tracheal intubation tube or a tracheotomy sleeve. Visual signal, you can judge whether the pressure of the inner air bag meets the requirements. That is, when the white color segment d on the indicator rod is stretched out, it means that the pressure in the inner air bag is low and needs to be inflated; when the green color segment c on the indicator rod is stretched out, it means that the pressure in the inner air bag is normal. When the red color segments b on the indicator rod are stretched out, it means that the pressure in the inner air bag is relatively high and needs to be deflated.
