Description

Saliva suction device

Technical Field

The utility model relates to the technical field of saliva suction, in particular to a saliva suction device.

Background technique

In the ICU ward, there are a large number of patients who cannot sit up because of medical tubes such as esophageal intubation in their mouths. This makes it impossible for the patients to close their mouths and drool, which can easily contaminate the beds and affect the physical and mental health of the patients and their families. In addition, the amount of saliva in patients with lung infections will increase significantly, and comatose patients cannot handle their saliva by themselves. Therefore, it is very important to discharge the saliva in the mouths of such patients in time. At present, there are generally two ways to deal with saliva: 1. Tracheotomy: first cut the patient's trachea, and then insert the suction tube into the patient's trachea to suck out the saliva and discharge it out of the body; 2. No tracheotomy: Place a suction tube of a saliva suction device in the patient's mouth to keep the patient's mouth in a state of continuous negative pressure suction, thereby helping the patient to suck out the saliva in the mouth and discharge it out of the body. Since no tracheotomy causes less damage to the patient and is easy to operate, it is more common in actual use.

The saliva suction device of the prior art has the following problems: 1. The suction hole on the suction tube is easy to suck the skin inside the patient's mouth under the action of negative pressure, so that the suction tube can no longer suck out the saliva in the mouth, and long-term suction of the skin inside the patient's mouth will also cause damage to the patient's oral skin, and in severe cases, it will cause congestion of the patient's oral skin; 2. The guide tube between the suction tube and the saliva collection bottle cannot be shaped, and is often in a laid state during use, which can be easily accidentally touched by the patient and his family members, causing the suction tube in the patient's mouth to damage the patient's mouth.

The Chinese patent with application number CN202121065395.5 discloses an oral low-negative pressure saliva drainage device, which includes a drainage part, a negative pressure suction tube, a negative pressure suction pump and a collection part. The drainage part is a hollow sphere with multiple through holes on the surface. The drainage part has a tubular structure, one end of the tubular structure is connected and communicated with one end of the negative pressure suction tube, and the other end extends to the side of the drainage part sphere away from the negative pressure suction tube. The end of the negative pressure suction tube away from the drainage part is connected to the negative pressure suction pump and the collection part. The drainage part of the device is easy to absorb the patient's oral skin under the action of negative pressure, so that the drainage part cannot continue to suck out the saliva in the patient's mouth, and the negative pressure suction tube cannot be shaped. If it is accidentally touched by the patient and his family, it is easy to cause the drainage part in the patient's mouth to cause damage to the patient's mouth.
