Description
Technical Field
The utility model relates to a nursing materials field of throat especially relates to a throat secretion drainage double cannula.
Background
When the secretion of the oral cavity and the nasal cavity is accumulated in the throat part, the secretion is invisible, and when the secretion is excessive, the secretion flows out through the mouth corner frequently, the secretion of the throat part is insufficiently sucked at the moment in a conventional way, the mucous membrane is also damaged, one disposable sputum suction tube is consumed for suction every time, and the suction is needed for several times or even ten to twenty times every day; in addition, the suction is not timely, the cleaning is avoided, the nursing workload is increased, and nursing articles such as napkins of patients are wasted.
Partial trachea cannula or trachea incision critically ill patients have more nasal cavity and oral secretion, or esophagus reflux exists, a large amount of secretion exists in the throat part and is easy to permeate into the air passage to cause or aggravate pulmonary infection, and full drainage is one of main infection prevention measures.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a pharyngeal secretion drainage double-sleeve.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a throat secretion drainage double-cannula comprises an outer cannula and an inner cannula, wherein the inner cannula is sleeved in the outer cannula, the front end opening of the outer cannula is closed, a plurality of asymmetric side openings are alternately reserved on two sides of the front tube wall of the outer cannula, an opening is arranged at the tail end of the outer cannula and connected with a flushing side tube, the tail end of the flushing side tube is a cover opening connector connected with an injector, and the inner cannula is connected with a negative pressure suction device for providing continuous negative pressure suction;
furthermore, the distance between the inner pipe wall of the outer sleeve (1) and the outer pipe wall of the inner sleeve (2) is 1.8-2.2 mm.
The outer sleeve is a silicone tube with the inner diameter of 5mm, the length of the outer sleeve is 25cm, the distance between the outer sleeve and the front end opening of the outer sleeve is within 10cm, the front pipe wall of the outer sleeve is provided with 8 side holes alternately reserved on two sides of the front pipe wall of the outer sleeve, the outer sleeve is asymmetric, and the diameter of each side hole is 2 mm; the opening of the flushing side pipe is positioned at a position 5cm away from the tail end, the inner diameter of the flushing side pipe is 2mm, and the tail end is provided with a cover opening connector which is provided with a cover and can be connected with an injector; the inner sleeve is a child sputum suction tube with the outer diameter of 2.7mm and the length of 470 mm;
the outer sleeve flushing side tube is flushed by injecting physiological saline into the injector at any time, and the inner sleeve tube is connected with a negative pressure suction apparatus for continuous negative pressure (less than 20kpa) suction;
the distance between the inner sleeve and the outer sleeve is about 2mm, and air, flushing fluid and drainage fluid can smoothly enter the device; the outer sleeve adopts a silicone tube, so that the outer sleeve is not easy to be attracted and collapsed by negative pressure, and plays a supporting role;
the front end of the outer sleeve is closed, so that the situation that the tissue is damaged and blocked by negative pressure suction due to the fact that the inner sleeve with negative pressure directly contacts mucosal tissue is avoided; the multiple side holes are beneficial to enlarging the suction range, and secretions from the nasal cavity to the throat can be sucked into the outer sleeve and are led out by negative pressure;
generally, the negative pressure is 10-20kpa, and secretion can be sucked out smoothly. The secretion is viscous and is diluted by injecting physiological saline through a lateral tube at any time.
From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: the double-sleeve continuous low negative pressure suction is adopted as the active drainage, so that the damage of the conventional suction tube negative pressure suction to the respiratory mucosa is avoided; the outer sleeve can be repeatedly washed, and the inner sleeve can be pulled out for washing, so that the blockage of the drainage tube is avoided; the secretion is continuous, so the drainage is continuous, and the drainage is more sufficient and effective.
