Sputum aspirator and control method thereof

Abstract

The invention provides a sputum aspirator and a control method thereof. The interior of a suction tube of the sputum aspirator is divided into two channels by a partition plate, the front end of the first working channel is provided with a head end module for collecting images, the head end module is connected with a control module through an image collecting cable, and the second working channel is used for sucking sputum and is communicated with a suction module. The control module is connected with the image acquisition module, a display device and the suction module, so that the sputum aspirator can acquire images and suck sputum, the acquired images are displayed through the display device, the medical staff can perform visual operation during sputum suction, and the accuracy and safety of an operation are improved. According to the sputum aspirator control method, the state of the suction tube is monitored through a temperature sensor and a humidity sensor so as to judge whether the suction tube is repeatedly used or not, marking is conducted through a repeated use prevention module, and therefore the suction tube can be prevented from being used for the second time, the cross infection of the patients can be effectively prevented, and the safety and sanitation of medical instruments can be improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sputum suction device and a control method thereof. Background technique [0002] In clinical practice, when there is too much sputum in the patient's trachea, it is easy to cause dyspnea. The general suction time of the sputum suction device should not exceed 15s / time. After all, there are foreign objects in the throat cavity, and the suction will generate a certain suction force. Excessively long operation time will make the patient feel uncomfortable, causing choking phenomenon, and It will be life-threatening, and after the sputum suction tube on the sputum suction device completes another sputum suction, there will be sputum residue on the outside of the tube, which must be cleaned before entering the trachea again for sputum suction. [0003] The sputum suction tube of the traditional sputum suction device is inserted into the patient's mouth by the doctor based on experie...

Problems solved by technology

The general suction time of the sputum suction device should not exceed 15s / time. After all, there are foreign objects in the throat cavity, and the suction will generate a certain suction force. Excessively long operation time will make the patient feel uncomfortable, causing choking phenomenon, and It will be life-threatening, and after the sputum suction tube on the sputum suction device completes another sputum suction, there will be sputum residue on the outside of the tube, which must be cleaned before entering the trachea for sputum suction again

[0003] The sputum suction tube of the traditional sputum suction device is inserted into the patient's mouth by the doctor based on experience, and then the sputum is sucked or rinsed. However, due to the limited capacity of the sputum suction tube and the limited operating field of view, it is necessary to repeatedly remove the sputum suction tube during operation. , to be used again after cleaning, resulting in inefficient and time-consuming sputum suction work, increasing the suffering of patients
