Description
Technical Field
The utility model belongs to the technical field of the supplementary technique of medical treatment and specifically relates to a dedicated breathing circuit combination of perioperative period.
Background
The connecting pipeline of the normal-time respirator consists of a breathing loop, a carbon dioxide monitoring line and a heat and moisture exchanger. In the clinical use process, due to the change of the operation mode or the operation proceeding state of the patient, the positions of the loop and the heat and humidity exchanger are changed correspondingly, which is easy to cause the following inconveniences:
(1) the heat and moisture exchanger has a relatively large volume and heavier weight relative to the loop, and the endotracheal tube is subjected to traction, distortion and deformation due to the sagging under the action of gravity, so that the risk of falling of the endotracheal tube is increased.
(2) The edges and corners of the heat and moisture exchanger are clear, and particularly in otorhinolaryngological operations, the operation has higher requirements on the placement of a loop, so that the heat and moisture exchanger is positioned above the forehead of a patient, and the forehead is pressed by the edges and corners of the heat and moisture exchanger to cause related pressure damage to a medical instrument, which usually completely conforms to the style or shape of the instrument. To avoid such pressure injuries, anesthesia nurses are routinely protected by a protective dressing applied to the patient's forehead, adding to the cost and time of medical care.
(3) The heat and humidity exchanger is often placed behind the carbon dioxide monitoring line, so that water vapor in the exhaled air and sputum which is coughed by choking cannot be filtered by the heat and humidity exchanger, the carbon dioxide monitoring line is blocked, the detected waveform is abnormal, even judgment of an anesthesiologist and an anesthesia nurse is interfered, and timely treatment of a patient by medical staff is influenced; the service life of the carbon dioxide monitoring line is reduced, and the medical cost is increased.
The Chinese patent application: CN103990216A discloses a multifunctional breathing loop connecting pipe, which comprises a main pipe, a side pipe, a telescopic extension pipe and a ventilator joint pipe. The hexagonal cover at the upper end of the main pipe is provided with a hole at the center, a small cover is arranged on the hole, and a one-way valve which is opened towards the inner direction of the main pipe is arranged in the hexagonal cover and can cover the hole at the center of the hexagonal cover. The middle part of the main pipe is connected with a side pipe, the side pipe is connected with a telescopic extension pipe, the telescopic extension pipe is connected with a respirator joint pipe, and the opening end of the respirator joint pipe is provided with an outer cover. The middle section of the main pipe is provided with a diaphragm-like regulating valve below the opening of the side pipe, and the diaphragm-like regulating valve comprises an upper fixed cover, a movable rotary vane, a plugging blade, a lower fixed cover and a U-shaped outer ring. The pipe wall of the main pipe below the diaphragm sample adjusting valve is double-layer, and a bayonet structure is formed. When the sputum is sucked, the sputum suction pipe and the one-way valve are relatively sealed, so that the use of a breathing machine is not required to be interrupted, and the sputum can be effectively prevented from splashing. When the pipe is blocked, the diaphragm sample adjusting valve can flexibly adjust the area of the blocked pipe, so that the patient can gradually adapt to the state of the blocked pipe. But the device is inconvenient to operate and is not capable of giving the patient a comfortable therapeutic experience.
Therefore, there is a need for a breathing circuit combination dedicated for perioperative period, which is convenient to operate, has a reasonable structure and is easy to disassemble, and can improve the use comfort of patients.
