technical field

The utility model relates to the field of humidifying devices for endotracheal tubes in tracheotomy operations, in particular to a device for continuously humidifying endotracheal tubes.

Background technique

Under normal physiological conditions, the humidity and temperature in the respiratory tract are stable, and the gas entering the human respiratory tract maintains a stable humidity state.

After the tracheotomy, the patient breathes through the endotracheal tube. However, the endotracheal tube does not have the function of constant temperature and humidification, resulting in low humidity of the gas entering the patient's respiratory tract, which easily leads to viscous sputum and difficulty in expectoration. In addition, it is easy to form phlegm scab, aggravate respiratory inflammation, reduce lung compliance, and lead to lung infection. Therefore, tracheal humidification is an essential nursing work.

At present, at home and abroad, the purpose of humidifying the trachea is mainly achieved through a temperature-humidity exchanger (artificial nose). The temperature and humidity exchanger is mainly made of a fine mesh structure device made of water-absorbing materials and hydrophilic compounds. It is exhaled by the patient to warm and humidify the inhaled gas, which can keep the pipeline itself dry and avoid air circulation in the ventilation loop. Coagulation of condensate, and has a certain filtering effect on bacteria. However, the price of the temperature and humidity exchanger is relatively expensive, which increases the treatment cost of ordinary patients. In addition, because the artificial nose is designed in a multi-layer mesh, patients often have difficulty breathing.

The present sustainable humidification endotracheal tube device is then worn around the patient's neck. Connect the free end of the catheter with the inner cannula on the patient, open the regulating valve, and the liquid medicine in the transparent medicine solution box will flow into the inner cannula drop by drop, thereby achieving the purpose of humidifying the gas in the inner cannula .

The ventilation tube of this solution ensures that the liquid medicine in the transparent medicine liquid box flows smoothly into the catheter, and avoids negative pressure in the transparent medicine liquid box from affecting the flow of the medicine liquid. When the liquid medicine in the transparent medicine liquid box is less, the medicine dispensing tube can be opened to replenish the medicine liquid in the transparent medicine liquid box, thereby ensuring the continuous humidification of the inner cannula of the patient by the device.

Preferred option 1: As the preferred option of the basic solution, an elastic plate is installed in the transparent liquid medicine box, and the elastic plate is located directly below the dispensing tube. One side of the elastic plate is bonded to the inner wall of the transparent liquid medicine box, and the other sides are dangling. The advantage of this solution is that the liquid medicine flowing from the dispensing pipe into the transparent liquid medicine box hits the elastic plate, and the elastic plate is deformed by the impact and then rebounds to further stir the liquid medicine to make the liquid medicine mix more evenly.

Preferred option 2: as the preferred option of the basic option or preferred option 1: a main one-way drain valve and a bypass pipe are sequentially installed on the catheter tube, the main one-way drain valve is located below the regulating valve, and the bypass pipe An elastic bag is installed on the free end of the pipe, and a secondary one-way drain valve is installed on the bypass pipe. The advantage of this solution is that the main one-way liquid discharge valve prevents the liquid in the catheter from flowing back, especially when the patient coughs, prevents the liquid medicine in the catheter from flowing back. When the patient coughs, the airflow generated makes the liquid in the inner cannula flow back. The main one-way liquid discharge valve prevents the backflow liquid from entering the transparent medicine solution box. At this time, the backflow liquid enters the elastic bag through the bypass tube. Because the secondary one-way liquid discharge valve is installed on the bypass pipe, the liquid in the elastic bag is prevented from flowing back into the bypass pipe.

The third preferred option: the preferred option of the second preferred option: a suction cup is installed on the transparent drug solution box, the inner hole of the drug dispensing tube is a tapered hole, and the small end of the tapered hole is close to the transparent drug solution box. The advantage of this scheme is that the installation of a suction cup on the transparent liquid medicine box helps the transparent medicine liquid box to be fixed on the patient's body surface. The removal of the plug, because the taper hole has a certain slope, is more convenient when pulling out the plug.
