Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail.
As shown in Figure 1, this utility model comprises a supervisor 1 being used for infusion chyme, medicine and moisture, and the upper end of supervisor 1 has the chimney-like supervisor joint 2 for connecting infusion tube.Tube wall near supervisor's 1 afterbody is provided with an antireflux air bag 3, and antireflux air bag 3 is wrapped in the periphery of supervisor 1, to form airtight air cavity between supervisor 1 tube wall.Antireflux air bag 3 connects a charging connector 5 by air injection pipe 4, for infusion gas in antireflux air bag 3.This utility model also comprises a pharyngeal attraction side pipe 6, the afterbody of pharyngeal attraction side pipe 6 also forms with it one along supervisor to downward-extension, have at the end of pharyngeal attraction side pipe 6 and attract side opening 7, the intracavity inter-connection of this attraction side opening 7 and pharyngeal attraction side pipe 6, but be not communicated with the inner chamber of supervisor 1, thus form the suction inlet of pars oralis pharyngis secretions.
In the above-described embodiments, air injection pipe 4 can be arranged in supervisor 1 tube wall, also can be arranged at supervisor 1 tube wall outer and is formed integrally with supervisor 1, but be preferably disposed in supervisor 1 tube wall, thus the external diameter of supervisor 1 can not be made to increase.
In the above-described embodiments, inside supervisor 1, be enclosed with the thread of an X-ray opaque, this thread auxiliary under to determine that supervisor 1 is in tram.
In the above-described embodiments, this utility model also comprises and is inserted into guiding steel wire 8 in supervisor 1 once supervisor's joint 2, its end extends to the tail end of supervisor 1, guiding steel wire 8 adopts rustless steel to make, surface scribbles coating liquid, and this coating liquid is the mixture of DOW CORNING 50%MDX4-4159 medical grade dispersion liquid and normal hexane; The upper end of guiding steel wire 8 is fixedly connected with a wire joint 9, with handled easily guiding steel wire 8.
In the above-described embodiments, side opening 7 is attracted can to arrange multiple, to increase pharyngeal attraction effect.
In the above-described embodiments, the tube wall of supervisor 1 near lower port place is provided with supervisor's side opening 10, supervisor's side opening 10 and the intracavity inter-connection being responsible for 1, and supervisor's side opening 10 can arrange multiple, to prevent supervisor 1 lower port from blocking, can improve infusion velocity simultaneously.
In the above-described embodiments, the material of supervisor 1, supervisor joint 2, air injection pipe 4 and pharyngeal attraction side pipe 6 is polyurethane.Antireflux air bag 3 is high appearance low-pressure type air bag, and recommendation intraluminal pressure is 20 ~ 30mmHg, to prevent the compression to esophageal wall.
In the above-described embodiments, the long 110 ~ 130cm of supervisor 1, antireflux air bag 3 is arranged on the gastroesophageal junction at distance supervisor 1 end 10 ~ 15cm place, attracts side opening 7 to be opened in distance supervisor end 40 ~ 45cm place.
Supervisor 1 in use, first inserts from patient's nasal cavity smoothly by this utility model, until the end of supervisor 1 arrives Stomach in Patients intracavity.After supervisor 1 indwelling puts in place by external charging connector 5 through air injection pipe 4 to injecting gas in antireflux air bag 3, antireflux air bag 3 expansion is opened fit tightly with gastroesophageal junction/distal esophagus wall thus play sealing process, when there being gastric content to esophageal reflux, play physical barrier effect, thus avoid and reduce the aspiration pneumonitis that causes because gastric content reflux erroneous aspiration enters trachea and suffocate.And pharyngeal attraction side pipe 6 can connect continuous negative pressure, the secretions sucking-off that pars oralis pharyngis is gathered, thus effectively reduce air draught danger by mistake.
The various embodiments described above are only for illustration of this utility model; wherein the structure of each parts, connected mode and operating procedure etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
