Description

Multi-direction adjustable breathing machine water collecting cup device and breathing machine Technical Field The utility model belongs to the technical field of respirators, and particularly relates to a multidirectional-adjustable respirator water collecting cup device and a respirator. Background In mechanical ventilation treatment of critically ill patients, a ventilator needs to deliver heated and humidified gas to the airway of the patient through a respiratory pipeline so as to compensate for the loss of physiological humidification function caused by an artificial airway and maintain the normal function of airway mucosa. The process inevitably generates condensed water, and if the condensed water is accumulated in a pipeline and flows back to the airway of a patient, complications such as infection, aspiration and the like are easily caused, so that the treatment safety is seriously influenced. For this purpose, it is common in the clinic to connect a water collection cup in the breathing circuit to collect and drain the condensed water. For example, chinese patent document CN215780785U discloses a breathing machine water collecting cup convenient for discharging condensed water, and its technical scheme is mainly characterized in that a buoyancy mechanism composed of a floating plate, a floating block and a sliding rod is arranged in the cup body, when the liquid level of the condensed water rises, the floating block floats upward to open a water outlet to realize automatic water discharge, and after the liquid level falls, the floating block falls back to re-close the water outlet. However, the above prior art solutions mainly focus on the drainage automation function of the water collection cup body, and there are still significant drawbacks in the actual complex clinical use process. In order to ensure that the condensed water can be effectively collected and smoothly discharged, the water collecting cup must be always positioned at the lowest point of the breathing pipeline and maintain a vertical posture. However, in clinical practice, due to the change of the patient's position, the lifting of the sickbed or the movement of the equipment, the spatial form of the breathing pipeline is frequently and dynamically changed, and the water collecting cup is extremely easy to incline and even horizontally deflect. Once the water collection cup deviates from the vertical state, an automatic drainage mechanism (such as a floating block structure in CN 215780785U) which is matched with buoyancy by relying on gravity in the water collection cup can fail due to the fact that the floating block cannot normally float vertically, so that the drainage function is interrupted. More importantly, the inclined or horizontal posture can change the liquid level and the flow direction of the condensed water in the cup, even if a part of the scheme is provided with an anti-backflow structure, the liquid condensed water is difficult to completely avoid flowing back to the main pipeline along the cup wall under the action of gravity when the pipeline pressure fluctuates or the body position changes, and the risk of inhalation damage of a patient is increased. In addition, the existing water collection cup is generally rigidly connected with a breathing pipeline through a tee pipe with a fixed angle or a simple threaded joint, and a convenient posture adjustment mechanism is lacked. When the position of the water collection cup needs to be corrected again, medical staff often need to twist the pipeline sections connected with the two ends of the water collection cup with two hands in a laborious manner, the operation process is tedious, and improper traction can interfere connection of the ventilation catheter and the airway of a patient. Therefore, there is a need to improve the prior art to solve the core technical problems that the water collecting cup in the ventilator pipeline is difficult to quickly, flexibly and reliably adjust and maintain in the vertical working posture when the pipeline form is changed due to the limitation of the connection structure between the water collecting cup and the pipeline, so that the condensate water cannot be ensured effectively and the hidden danger of backflow cannot be avoided fundamentally. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a multi-direction adjustable breathing machine water collecting cup device and a breathing machine, so as to solve the problem that the conventional water collecting cup is difficult to flexibly adjust along with the change of the form of a pipeline and maintain the vertical posture. In order to achieve the above purpose, the utility model adopts the following technical scheme: In a first aspect, the utility model provides a multi-direction adjustable breathing machine water collecting cup device, which comprises a three-way pipe, a multi-direction adjusting mechanism and a water coll
