Description

A device for draining oral secretions

technical field

The utility model relates to the technical field of chemotherapy equipment, in particular to a device for draining oral secretions.

Background technique

In clinical practice or during surgery, patients need to install devices such as tracheal intubation or oropharyngeal ventilation tubes. Both tracheal intubation and oropharyngeal ventilation tubes extend into the patient's body through the patient's mouth, resulting in the patient's mouth not being able to be closed for a long time. In the open state, as shown in Figure 1 (tracheal intubation and oropharyngeal ventilation tubes are usually fixed in the patient's mouth by tape), the oral cavity secretes a large amount of secretions (such as saliva, saliva, etc.), and it is very inconvenient to swallow, making it difficult to swallow. Oral secretions will flow out along one or both sides of the mouth under the action of gravity. In addition, for patients with tracheal intubation and under anesthesia, there is also the problem of oral secretions flowing out along the corners of the mouth. Not only is it easy to soil the sick clothes and bed sheets, which is unsightly, but also requires medical staff or their family members to clean up from time to time, which increases the workload of medical staff and their family members.

Utility model content

The purpose of this utility model is to improve the deficiencies existing in the prior art, and to provide a device for draining oral secretions, which has a simple structure and low cost, can drain and temporarily store the secretions from the corners of the mouth, and is easy to wear.
