Description

Suction object guiding device and suction object suction system Technical Field The present disclosure relates to an adherend guiding device and an adherend suction system. Background Due to aging, diseases, and the like, it may be difficult to discharge or swallow an object to be sucked, which is present in the human body, from the body, such as sputum, saliva, or nasal discharge, which is accumulated in the pharynx, by coughing or swallowing. If such an object to be sucked enters the trachea, it causes dyspnea, choking, pneumonia, and atelectasis. Therefore, it is necessary to suck and remove the sucked object by using a suction catheter or the like connected to the suction tube of the suction device. When an aspiration catheter is used to aspirate an aspiration object such as sputum, if the end of the aspiration catheter does not reach the aspiration object, a sufficient aspiration effect cannot be obtained. Therefore, by inserting the aspiration catheter into the lower respiratory tract, there is a possibility that damage is caused to the respiratory tract. As a related art for performing sputum aspiration, for example, patent document 1 discloses an aspiration device for mechanically applying negative pressure to the lung of a patient after positive pressure is applied (MECHANICAL INSUFFLATION-Exsufflation: hereinafter referred to as MI-E), thereby guiding sputum in the lung to the upper respiratory tract, and aspirating and collecting the sputum by using an aspiration catheter. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2013-524202 (paragraph 0017 of the specification) Disclosure of Invention Problems to be solved by the invention By means of sputum aspiration by the mechanical cough assist device (MI-E), sputum is guided to the upper respiratory tract, and thus low invasive sputum aspiration that is less likely to damage the respiratory tract by aspiration catheters can be achieved. However, sputum aspiration of mechanical cough assist devices (MI-E) requires skilled techniques for mechanical manipulation and setting. Therefore, it is desired to more easily guide an object to be suctioned such as sputum to the upper respiratory tract side. The present disclosure has been made in view of the above-described problems, and an object thereof is to more easily guide an object to be suctioned to the upper respiratory tract side. Means for solving the problems An object to be sucked guiding device guides an object to be sucked from a living body to an upper respiratory tract side, and the object to be sucked guiding device includes an object to be sucked discharging port capable of discharging the object to be sucked, a patient side connection interface capable of being connected to a patient side, an inhalation interface capable of being connected to an inhalation device, and a switching valve for switching a connection source of the patient side connection interface to either one of the object to be sucked discharging port and the inhalation interface. According to one aspect of the present disclosure, the connection source of the patient-side connection interface of the suction object guiding device connected to both the suction device and the inhalation device can be easily switched by the switching valve. Therefore, after the patient-side connection port is connected to the ventilation member for wearing a human body to perform positive pressure ventilation, the switching operation of the connection source of the patient-side connection port is performed by the switching valve, and the suction to guide the suction object to the upper airway side by the negative pressure can be easily performed. Another aspect of the present disclosure is an aspiration system for aspirating an aspiration from a living body, comprising an aspiration device provided with an aspiration tube, the aspiration guide device connected to one end of the aspiration tube, and an aspiration device connected to an aspiration interface of the aspiration guide device. According to another aspect of the present disclosure, after the patient-side connection interface of the suction-object guide tube connected to both the suction device and the suction device is connected to the ventilation member for wearing the human body and positive-pressure ventilation is performed, the switching operation of the connection source of the patient-side connection interface is performed by the switching valve and the connection source is communicated. This makes it possible to easily perform evacuation by which the suction target is guided to the upper airway side by negative pressure. Effects of the invention According to the present disclosure, the suction object can be more easily guided to the upper respiratory tract side.
