Description

A manual suction device

technical field

The utility model relates to the technical field of medical instruments, in particular to a manual phlegm suction device.

Background technique

Sputum suction is a common operation in clinical practice, and it is of great significance to keep the patient's airway unobstructed, prevent suffocation, clear airway secretions and reduce the rate of lung infection. At present, most wards of the hospital are generally equipped with a central negative pressure suction interface, but in some auxiliary departments, such as radiology, B-ultrasound room, magnetic resonance examination room and other places, there is often no central negative pressure suction interface, and only electric suction can be used. The sputum suction device is used for sputum suction, while the electric sputum suction device relies on a fixed power supply and is too large to carry. Therefore, critically ill patients must rely on manual sputum suction devices when they are in transit or going out for inspection.

A commonly used manual sputum suction device is a 50ml syringe connected to a sputum suction tube, which uses the negative pressure generated by the suction piston to suck out sputum. The cooperation of both hands is required, and the rotation and twitching of the suction tube cannot be taken into account during single-person operation, and the negative pressure generated is very short and limited. At the same time, the sputum is directly sucked into the syringe, which will also affect the next suction. In addition, it is not easy to form a tight connection between the nipple of the syringe and the suction tube, and the suction tube is prone to loosening, resulting in a delay in rescue time. The other is to use a device similar to a milk puller, which is also difficult to generate a relatively stable negative pressure that lasts for a long time, and the operation is time-consuming and laborious.
