Abstract
A trachea cannula port stopper relates to the technical field of medical appliances, consists of a cannula (1) and a cannula cap (2), and is characterized in that an annular projection (3) is arranged on the inner wall of the upper end of the cannula (1) which has the internal diameter fitting with the external diameter of a trachea cannula, and the outer wall of the upper end of the cannula (1) is threaded with the cannula cap (2); and three air vents (4) with the same areas are longitudinally and sequentially formed in the cannula cap (2), and the area sum of the three air vents (4) is the same as the port area of the cannula (1). The trachea cannula port stopper has the advantages that the trachea cannula port stopper has a simple structure, is safe and convenient to use, and can accurately plug step by step, so no stimulus can be caused to the respiratory tract.
Description
Technical field: this utility model relates to the medical instruments technical field, specifically a kind of tracheal intubation end opening blockage.
Background technology: to urgent patient that can not eupnea, need tracheostomize to insert outer tube and help patient respiration clinically.Outer tube can be attempted progressively tube sealing before being pulled out trachea, treat that patient is emotionally stable fully can extract after adapting to.As carrying out shutoff with cotton balls, roller, adhesive plaster etc., still there are many shortcomings in clinically for many years some simple and crude methods that adopt more: the one, and these cotton fiber article shape are irregular and run into very easily humidity of secretions, influence the plugging effect; The 2nd, cotton fiber is prone to get into air flue with breathing, and causes respiratory tract and to cause the patient uncomfortable and infect; The 3rd, can not guarantee succinct and firm fixing, there is plug to crash into the danger that air flue causes respiratory tract obstruction.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, safe in utilization, convenient, the tracheal intubation end opening blockage that can progressively carry out shutoff.
The purpose of this utility model is achieved in that this tracheal intubation end opening blockage is made up of sleeve pipe, sleeve cap, and the sleeve pipe upper end inwall that internal diameter and tracheal intubation external diameter adapt is provided with annular protrusion, and the upper end outer wall thread is connecting sleeve cap; Sleeve cap vertically has three air-vents that area is identical successively, and the area summation of three air-vents is identical with the sleeve pipe orifice area.
Tracheal intubation is before being pulled out trachea, and in the tracheal intubation upper end, the turning set pipe cap makes sleeve pipe with the nethermost air-vent sealing of sleeve cap then, crosses certain hour and confirms progressively to seal other two air-vents again after the no abnormal reaction of patient with casing pipe sleeve in elder generation.
The advantage of this utility model: simple in structure, safe in utilization, convenient, can progressively carry out accurate shutoff, can not cause stimulation to respiratory tract.
Description of drawings: accompanying drawing 1 is the structure cutaway view of this utility model.
The specific embodiment: describe in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this tracheal intubation end opening blockage is made up of sleeve pipe 1, sleeve cap 2; The sleeve pipe 1 upper end inwall that internal diameter and tracheal intubation external diameter adapt is provided with annular protrusion 3, and the upper end outer wall thread is connecting sleeve cap 2; The area summation that sleeve cap 2 vertically has identical 4, three air-vents 4 of air-vent of three areas successively is identical with sleeve pipe 1 orifice area.
