Description

Disposable slip-off preventing can the nasopharynx airway of oxygen supply
Technical field
This utility model belongs to medical auxiliary apparatus, and specifically a kind of disposable slip-off preventing can the nasopharynx airway of oxygen supply.
Background technology
In prior art, disposable nasopharynx airway belongs to common is also conventional medical auxiliary apparatus.When specifically using, there is a lot of inconvenience in nasopharynx airway, such as: with oxygen hose with the use of time, because the diameter of conduit is much larger than the diameter of oxygen hose, after oxygen passes into nasopharynx airway, all driven out of external with the general breathing of people greatly; Nasopharynx airway directly fills in the respiratory tract of nasal cavity, when nasopharynx airway twists time, can produce pessimal stimulation to the respiratory tract of human body.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of novel disposable conduit, concrete technical scheme is as follows:
Disposable slip-off preventing can the nasopharynx airway of oxygen supply, comprises catheter tube, it is characterized in that the fixing adapter also comprising catheter tube; The body material of described conduit is silica gel material; The head end of catheter tube is provided with horn opening, and the tail end of catheter tube is angle; Described fixing adapter comprises two sections that are interconnected, and the radius of two sections of fixing adapters is different; The external diameter of the fixing adapter of small radii one section is not less than the internal diameter of the head end of catheter tube, and the fixing adapter that small radii is a section is stretched in the head end of catheter tube; Be extended with fin respectively in the two bottom sides of the fixing adapter of relatively large radius one section, two fin area differences, be divided into large fin and little fin, the most advanced and sophisticated homonymy of large fin and described angle; Described large fin and little fin are all connected with belt, and the end of two belts is provided with corresponding connecting device;
The inwall of described catheter tube is provided with oxygen ventilation pipe along catheter tube length direction, and the head end of oxygen ventilation pipe stretches out the relatively large radius one section of fixing adapter, and the tail end of oxygen ventilation pipe above the tip of described angle, and does not expose the tail end of catheter tube; The inwall of the end-position of catheter tube is provided with the circulating line around catheter tube axis, and circulating line is furnished with multiple through hole, and the opening of through hole is towards the tail end of catheter tube; Circulating line is communicated with the tail end of described oxygen ventilation pipe.
Described connecting device is self-adhesion velcro.
When reality uses, this conduit stretches into nasal cavity by nostril, side, and large fin is in this nasal cavity side, little fin gear on opposite side nasal cavity, by belt and self-adhesion velcro around to back head, and fastening.
The head end of oxygen ventilation pipe is connected with oxygen hose attachment cap; Also comprise external oxygen hose; The escape pipe of external oxygen hose has one, and it connects described oxygen hose attachment cap, and the air inlet pipe of external oxygen hose is connected with standard oxygen inlet pipe connection.The sectional area sum of described multiple through hole be catheter tube intracavity section long-pending 1/6.For the through hole number on unit length circulating line, the through hole number near the tail end of oxygen ventilation pipe is less than the through hole number of the tail end away from oxygen ventilation pipe.Be embedded in the wall of catheter tube in the tube chamber of described oxygen ventilation pipe.
Adopt oxygen ventilation pipe and connect circulating line, making oxygen be goed deep into respiratory tract, and can not be blown out by breath external halfway.1/6 choose of section area ratio, is through and derives and experiment, and consider volume and the pressure of pure oxygen content in medical oxygen and external gas of breathing out, choose the ratio of 1/6, pure oxygen utilization rate is the most reasonable.
Meanwhile, the oxygen ventilation tubular construction of built-in type considers that the processing in catheter tube forming process realizes difficulty, and the stressing conditions of catheter tube own and the scheme adopted.In addition, oxygen ventilation pipe is imbedded in catheter tube body wall, also can reduce the space hold of conduit cavity, thus sputum aspirator tube can be stretched into easily.
Be coated with lignocaine slow releasing medicinal rete outside described catheter tube, outside lignocaine slow releasing medicinal rete, be coated with paraffin lube layer.Further minimizing conduit is to the stimulation of respiratory tract.
Accompanying drawing explanation
Fig. 1 is the structural representation of this conduit;
Fig. 2 is the structural representation of oxygen hose attachment cap;
In Fig. 1, the fixing adapter 2-2 of catheter tube 1, fixing adapter 2, the fixing adapter 2-1 of relatively large radius one section, small radii one section, the head end 3 of catheter tube, the tail end 4 of catheter tube, large fin 5, little fin 6, oxygen hose attachment cap 7, oxygen ventilation pipe 8, circulating line 9.
Detailed description of the invention
This utility model is further illustrated as follows below in conjunction with accompanying drawing and detailed description of the invention:
As Fig. 1, a kind of disposable slip-off preventing can the nasopharynx airway of oxygen supply, comprises catheter tube, it is characterized in that the fixing adapter also comprising catheter tube; The body material of described conduit is silica gel material; The head end of catheter tube is provided with horn opening, and the tail end of catheter tube is angle; Described fixing adapter comprises two sections that are interconnected, and the radius of two sections of fixing adapters is different; The external diameter of the fixing adapter of small radii one section is not less than the internal diameter of the head end of catheter tube, and the fixing adapter that small radii is a section is stretched in the head end of catheter tube; Be extended with fin respectively in the two bottom sides of the fixing adapter of relatively large radius one section, two fin area differences, be divided into large fin and little fin, the most advanced and sophisticated homonymy of large fin and described angle; Described large fin and little fin are all connected with belt, and the end of two belts is provided with corresponding connecting device; The inwall of described catheter tube is provided with oxygen ventilation pipe along catheter tube length direction, and the head end of oxygen ventilation pipe stretches out the relatively large radius one section of fixing adapter, and the tail end of oxygen ventilation pipe above the tip of described angle, and does not expose the tail end of catheter tube; The inwall of the end-position of catheter tube is provided with the circulating line around catheter tube axis, and circulating line is furnished with multiple through hole, and the opening of through hole is towards the tail end of catheter tube; Circulating line is communicated with the tail end of described oxygen ventilation pipe.Described connecting device is self-adhesion velcro.The head end of oxygen ventilation pipe is connected with oxygen hose attachment cap; Also comprise external oxygen hose; The escape pipe of external oxygen hose has one, and it connects described oxygen hose attachment cap, and the air inlet pipe of external oxygen hose is connected with standard oxygen inlet pipe connection.The sectional area sum of described multiple through hole be catheter tube intracavity section long-pending 1/6.For the through hole number on unit length circulating line, the through hole number near the tail end of oxygen ventilation pipe is less than the through hole number of the tail end away from oxygen ventilation pipe.Be embedded in the wall of catheter tube in the tube chamber of described oxygen ventilation pipe.Be coated with lignocaine slow releasing medicinal rete outside described catheter tube, outside lignocaine slow releasing medicinal rete, be coated with paraffin lube layer.
