Abstract

An esophagus stomach tube anti-reflux device solves the problems that a stomach tube and a three-cavity two-sac tube are difficult to place, an air passage is easy to block, and a patient cannot be effectively prevented from reflux and aspiration; the esophagus trachea cannula comprises an esophagus tube and a stomach cavity tube, wherein a first air bag and a first inflation tube communicated with the first air bag are connected to the esophagus tube, the first air bag is arranged at the position, close to the tail end, of the esophagus tube, a head end of the esophagus tube is communicated with a conversion joint, the conversion joint is connected with a breathing device and can be used for judging whether the esophagus tube is mistakenly inserted into the cavity of the airway or not when the esophagus tube is inserted into the cavity of the airway, positive pressure ventilation is provided if the esophagus tube is mistakenly inserted into the airway and dyspnea occurs, a second air bag and a second inflation tube communicated with the second air bag are connected to the stomach cavity tube, and head ends of the first inflation tube and the second inflation tube are both connected with inflation valves; the utility model increases the comfort and safety of the patient, increases the success rate of first implantation, reduces the reflux prevention aspiration rate, and further reduces the reflux of the patient through the second air bag.

Description

Esophagus stomach tube anti-reflux device

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to an esophagus and stomach tube anti-reflux device.

Background

Aspiration, especially coma aspiration, is occurred frequently in clinic, the hazard is serious, and the existing anti-reflux aspiration device comprises an anti-aspiration stomach tube and a three-cavity two-bag tube. The disadvantage of preventing the stomach tube from being sucked by mistake: the stomach tube is soft, the tube cavity is large, and the coma patient is difficult to insert; there is a risk of blocking the airway by the wrong entry into the trachea. The defects of the Sengstaken-Blakemore tube: the cavity is large in volume, the designed function mainly aims at the hemorrhage of the digestive tract, and the placement is difficult and the use is inconvenient; there is a risk of blocking the airway by the wrong entry into the trachea.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems, the utility model provides an anti-reflux device for an esophagus and stomach tube, which solves the problems that the stomach tube and a three-cavity two-sac tube are difficult to insert, the air passage is easy to block, and the reflux and aspiration of a patient cannot be effectively prevented.

In order to achieve the above object, the present invention provides the following technical solutions; the esophagus stomach tube comprises an esophagus tube and a stomach cavity tube, wherein a first air bag and a first inflation tube communicated with the first air bag are connected to the esophagus tube, the first air bag is arranged at the position, close to the tail end, of the esophagus tube, a conversion joint is communicated with the head end of the esophagus tube, a second air bag and a second inflation tube communicated with the second air bag are connected to the stomach cavity tube, and inflation valves are connected to the head ends of the first inflation tube and the second inflation tube.

Compared with the prior art, the utility model has the beneficial effects that: the utility model increases the comfort and safety of the patient, increases the success rate of first implantation, reduces the reflux prevention aspiration rate, and further reduces the reflux condition of the patient through the second air bag.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model. In the drawings:

fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1-esophageal tube, 2-gastric lumen tube, 3-first air bag, 4-first inflation tube, 5-conversion joint, 6-second air bag, 7-second inflation tube and 8-inflation valve.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

Including oesophagus pipe 1 and stomach chamber pipe 2, be connected with first gasbag 3 on the oesophagus pipe 1 and with first gas tube 4 of first gasbag 3 intercommunication, first gasbag 3 is close to terminal position at oesophagus pipe 1, the head end intercommunication of oesophagus pipe 1 has crossover sub 5, be connected with second gasbag 6 on the stomach chamber pipe 2 and with second gas tube 7 of second gasbag 6 intercommunication, the head end of first gas tube 4 and second gas tube 7 all is connected with inflation valve 8.

The esophagus pipe 1 is put into through nose or via mouth, the material of esophagus pipe 1 is through special moulding a little stereoplasm, stomach cavity pipe 2 is soft, so the success rate height just can be put into to esophagus pipe 1, the stomach tube is soft little to the damage of gastric mucosa, be convenient for insert patient's throat, esophagus pipe 1 is about 20-25cm long, after inserting the throat, aerify first gasbag 3 through first gas tube 4, the inflation volume is about 30-40mmHg, first gasbag 3 constantly expands after aerifing and fixes a position esophagus pipe 1 in patient's esophagus, the near-mouth end of esophagus pipe 1 passes through crossover sub 5 and connects breathing machine or breathing bag, can judge whether the trachea is gone into by mistake to esophagus pipe 1, concrete judgement method is: when the esophagus pipe 1 is positioned to the throat of a patient, inflate first gasbag 3, need connect breathing machine or breathing bag through crossover sub 5, can fluctuate to judge whether in the air flue through the mould lung to the patient that has spontaneous respiration, can judge whether the esophagus pipe 1 mistake gets into the air flue through the breathing machine or press the mode auscultation breath sound that the breathing bag ventilated to no spontaneous respiration patient, like the airway is gone into to the esophagus pipe 1 mistake, also can prevent through breathing machine or breathing bag that esophagus pipe 1 mistake from getting into the air flue and causing the condition of suffocation for the patient.

After the stomach tube 2 is prevented from mistakenly entering an airway, the soft stomach cavity tube 2 is inserted into the stomach of a patient from the cavity of the esophagus tube 1, the length of the inserted stomach tube is 50-65cm until a small amount of gastric juice is sucked from the near-end of the stomach cavity tube 2, then the second air bag 6 is inflated through the second inflation tube 7, the inflation amount is 40-50mmHg, the inflated second air bag 6 is in a pumpkin shape, the blockage of the cardia is facilitated, after the inflation is finished, the stomach tube is slightly lifted upwards, the cardia can be blocked through the second air bag 6 after resistance is met, and the injury of the patient caused by the regurgitation of stomach food is effectively prevented.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
