Description

Technical Field

[0001] The utility model relates to the technical field of sputum suction devices, in particular to a portable sputum suction device. Background Art

[0002] The intensive care unit is the intensive care unit, also known as the comprehensive treatment room of the intensive care unit. Treatment, nursing and rehabilitation can be carried out simultaneously. It provides isolation places and equipment for critically ill or comatose patients, and provides the best nursing, comprehensive treatment, medical and nursing integration, early postoperative rehabilitation, joint care and exercise therapy and other services, and targeted monitoring and supply. It is also called the intensive care unit. It is a medical organization management form that integrates modern medical care, nursing and rehabilitation technologies that emerged with the common development of medical, nursing, rehabilitation and other professions, the birth of new medical equipment and the improvement of the hospital management system. Aspirators are used in intensive care units to suction sputum for patients. Specifically, for patients with artificial airways such as endotracheal intubation or endotracheal cannulae, the artificial airways ensure the patency of the airways and save the lives of critically ill patients on the one hand, but on the other hand, they seriously damage the respiratory system's own cilia-mucus defense mechanism, increase bacterial fixation and the occurrence of ventilator-associated pneumonia. Patients with open artificial airways need to use external suction to avoid the harm caused by sputum accumulation. In clinical use, we found that the sputum suction devices in the prior art are generally electric sputum suction devices or disposable manual sputum suction devices.

[0003] In the authorized patent document with publication number CN220404514U, a portable sputum suction device is disclosed, including a sputum storage container, a sputum suction tube and a negative pressure generating device, the sputum storage container includes a bottle body, a cover body, a first joint and a second joint, the bottle body is threadedly connected to the cover body, the output end of the sputum suction tube is threadedly connected to the inner wall of the first joint, the first joint and the second joint are respectively arranged on the cover body, and a first one-way valve is arranged at the lower end of the second joint, the first joint is connected to the sputum suction tube, and the second joint is connected to the negative pressure generating device. A portable sputum suction device does not need to be discarded after the sputum suction is completed, which solves the problem of resource waste.

This design can make the cleaning of the bottle body more convenient.

[0004] When the above device is implemented, the bottle body is used to collect sputum, and when the sputum is full, it will overflow and may even enter the negative pressure tube, thereby sticking to the inner wall of the negative pressure tube and seriously sticking to the filter, and even entering the negative pressure mechanism of the sputum suction device, thereby providing an anti-overflow device.

An injection tube 9 is installed on the top wall, and the injection tube 9 extends to the upper end of the cover 3. A negative pressure tube 11 is installed on the upper end of the injection tube 9, and a solenoid valve 8 is installed inside the negative pressure tube 11. The negative pressure tube 11 is fixedly installed on the sputum suction device body 1, and the solenoid valve 8 is electrically connected to the passive switch 7. A warning light 14 is installed on the upper end of the sputum suction device body 1, and the warning light 14 is electrically connected to the passive switch 7. A buzzer 15 is installed on the upper end of the sputum suction device body 1 on one side of the warning light 14, and the buzzer 15 is electrically connected to the passive switch 7.

[0031] In the technical solution of the utility model, negative pressure operation can be performed on the inside of the collecting bottle 2 through the negative pressure tube 11, which is convenient for suctioning sputum for patients. When the collecting bottle 2 collects sputum to a moving degree, the float plate 5 will float up with the sputum, and then the float plate 5 will contact the passive switch 7, so that the passive switch 7 closes the solenoid valve 8, and then the negative pressure ends, preventing the sputum from overflowing in the collecting bottle 2.

[0032] In addition, after the passive switch 7 is triggered, the warning light 14 can be triggered to remind the staff, and after the passive switch 7 is triggered, the buzzer 15 can be triggered to further remind the staff.

[0033] In the technical solution of the utility model, if Figure 1 As shown, a connecting tube 10 is installed at the upper end of the cover 3, and the connecting tube 10 extends to the interior of the collecting bottle 2. The setting of the connecting tube 10 can connect the sputum suction catheter, so as to facilitate the sputum suction for the patient. A filter 12 is installed inside the negative pressure tube 11, and the filter 12 can filter the negative pressure tube 11.

[0034] In the technical solution of the utility model, if Figure 1 As shown, an active switch 17 is installed on the inclined surface above the suction device body 1, and an instrument panel 13 is installed on one side of the suction device body 1 located on the side of the active switch 17. The active switch 17 is electrically connected to the instrument panel 13 and the solenoid valve 8. The setting of the active switch 17 can facilitate the staff to actively operate the suction device body 1, and the instrument panel 13 can observe the negative pressure data.

[0035] In the technical solution of the utility model, if Figure 1 As shown, a handle 16 is installed at the upper end of the suction device body 1. The setting of the handle 16 can facilitate the staff to take the suction device body 1. The lower end of the suction device body 1 is fixedly connected with multiple supporting feet 18.

The supporting feet 18 can support the suction device body 1, and the setting of the anti-skid pads 19 can prevent the suction device body 1 from slipping.

[0036] When in use, first confirm that the suction device body 1, collecting bottle 2, cover 3, guide rod 4, float plate 5, fixing plate 6, passive switch 7, injection tube 9, negative pressure tube 11, solenoid valve 8 and other components are intact and installed correctly, check and confirm that the power supply is normal and the battery is fully charged, press the active switch 17 above the suction device body 1 to start the suction device, the instrument panel 13 will display the current working status, such as negative pressure value, power level, etc., connect the suction tube to the connecting tube 10 to ensure a tight connection, insert the suction tube into the patient's mouth or throat, and start the suction operation. As the suction progresses, sputum will be sucked into the collecting bottle 2, and the float plate 5 will slide upward on the guide rod 4 as the sputum increases. When the float plate 5 rises to a certain position and contacts the passive switch 7, the passive switch 7 will be triggered, and the triggering of the passive switch 7 will send a signal to the solenoid valve 8 sends a signal. After receiving the signal, the solenoid valve 8 will immediately close and stop the generation of negative pressure, which will prevent more sputum from being sucked in, thereby preventing the collecting bottle 2 from overflowing. At the same time, if the warning light 14 and the buzzer 15 are installed, they will start at the same time, emitting sound and light signals to remind medical staff to pay attention. After receiving the alarm prompt, the medical staff should immediately stop the sputum suction operation, carefully remove the collecting bottle 2 from the sputum suction device body 1, and deal with the sputum therein. After dealing with the sputum, reinstall the collecting bottle 2 on the sputum suction device body 1, press the active switch 17, reset the sputum suction device, and return it to the standby state. This workflow ensures that the portable sputum suction device can prevent overflow when collecting sputum, and prompts medical staff or auxiliary personnel to deal with it in time through alarm, thereby ensuring the safety of patients and the smooth progress of medical care.
