Description

A special breathing circuit combination for perioperative period

technical field

The utility model relates to the technical field of medical assistance, in particular to a special breathing circuit combination for the perioperative period.

Background technique

Usually, the ventilator connection pipeline is composed of a breathing circuit, a carbon dioxide monitoring line and a heat and moisture exchanger. During clinical use, due to the change of the patient's operation method or the state of the operation, the position of the circuit and the heat and moisture exchanger will change accordingly, which will easily cause the following inconveniences:

①The volume of the heat and moisture exchanger is relatively large, and its weight is heavier than that of the circuit. Due to the sagging of gravity, the endotracheal tube is pulled and twisted, which increases the risk of endotracheal tube prolapse.

②The heat and moisture exchanger has sharp edges and corners. Especially in ENT surgery, the operation has higher requirements for circuit placement, so that the location of the heat and moisture exchanger is above the patient's forehead, and the forehead is pressed by the edges and corners of the heat and moisture exchanger, resulting in medical device correlation. A pressure injury, usually conforming exactly to the pattern or shape of the device. In order to avoid this kind of pressure injury, anesthesia nurses routinely use protective plasters to protect the patient's forehead, which increases medical costs and time.

③The heat and moisture exchanger is often placed behind the carbon dioxide monitoring line, so that the water vapor in the exhaled breath and the sputum coughed up cannot be filtered by the heat and humidity exchanger, which in turn blocks the carbon dioxide monitoring line, resulting in abnormal detection waveforms and even interference with anesthesiologists The judgment of the anesthetist and the nurse affects the timely treatment of the patient by the medical staff; the service life of the carbon dioxide monitoring line is reduced, and the medical cost is increased.

Chinese patent application: CN103990216A discloses a multifunctional breathing circuit connection tube, including a main pipe, a side pipe, a telescopic extension pipe and a ventilator joint pipe. There is a hole in the center of the hexagonal cover at the upper end of the main pipe, and a small cover is arranged on the hole. The inside of the hexagonal cover is provided with a one-way valve that is opened toward the inside of the main pipe, and the hole in the center of the hexagonal cover can be covered. The middle part of the supervisor is connected with a side pipe, and the side pipe is connected with the telescopic extension pipe, and the telescopic extension pipe is connected with the ventilator joint pipe, and an outer cover is arranged at the open end of the ventilator joint pipe. The middle section of the main pipe has an aperture-like regulating valve below the opening of the side pipe, which includes an upper fixed cover, a movable rotary piece, a sealing blade, a lower fixed cover and a U-shaped outer ring. The pipe wall of the main pipe below the aperture-like regulating valve is double-layered, forming a bayonet structure. When sucking sputum, the space between the sputum suction tube and the one-way valve is relatively airtight, so there is no need to interrupt the use of the ventilator, and it can effectively prevent sputum from splashing. When the tube is blocked, the aperture-like regulating valve can flexibly adjust the area of the blocked tube, so that the patient can gradually adapt to the blocked tube. However, the device is inconvenient to operate and cannot give patients a comfortable treatment experience.

So to sum up, there is an urgent need for a perioperative special breathing circuit combination that is easy to operate, reasonable in structure, easy to disassemble, and can improve patient comfort. combination, has not been reported yet.
