Description

Oral cavity continuous negative pressure suction tube and suction system

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to oral cavity is vacuum suction tube and suction system lasted.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Trachea cannula and tracheotomy are widely applied to clinic as a common respiratory treatment mode for critically ill patients. However, after the trachea is intubated and cut, the oral cavity is in a long-time open state, so that a patient cannot chew, swallow and eat normally, the resistance and self-cleaning effect of the oral mucosa are reduced, and oral bacteria are proliferated in a large quantity; in addition, the patient has serious illness and reduced immunity, the protective function of epiglottis is reduced or lost, and the probability of oral infection transfer is increased; in addition, the use of sedative and muscle relaxant drugs increases the incidence of Ventilator Associated Pneumonia (VAP) due to patient aspiration, especially occult aspiration. The oral secretion of a patient is sucked in time, the accumulation of the oral secretion is reduced, the proliferation and reproduction of oral bacteria are reduced, the ectopic position of oral flora is reduced, the incidence rate of the ventilator-associated pneumonia is reduced, and the occurrence time of the ventilator-associated pneumonia is prolonged. In addition, the secretion in the oral cavity of the patient can flow out through the corners of the mouth when the secretion is much, the flowing secretion pollutes the pillowcase and the bed sheet of the patient, and the comfort level of the patient is reduced. The nurse frequently wipes the secretion at the corners of the mouth of the patient, the bed sheet and the pillow case are replaced, and the workload of the nurse is increased.

The inventor knows that in the existing oral surgery or oral plastic process, a gas tube is often used to suck saliva secretion in the oral cavity, but the common negative pressure suction tube is only provided with a fixed suction head at the tail end, and the suction head is provided with a suction hole. It has the following disadvantages:

(1) since the suction head occupies a small volume, its suction effect depends on the placement position of the suction head, and saliva secretion tends to accumulate in the oral cavity for a long time when the suction holes are not located at the lowest point of the oral cavity.

(2) Because the position of the suction head relative to the buccal side of the oral cavity can not be adjusted, the suction hole can be tightly attached to the skin on the buccal side when the oral cavity is used, and the skin on the buccal side is ulcerated due to long-time negative pressure suction, so the oral cavity is not suitable for long-time use.

(3) In the negative pressure suction tube which partially increases the volume of the suction head, the suction head is generally in a trumpet-shaped structure with the increased volume, and in the structure, the part which is still close to the buccal side and participates in the suction of the saliva secretion at any time is wasted, and most volume is wasted.
