Abstract
The utility model discloses a preventing inspiratory regurgitation stomach tube, comprising a medical stomach tube, wherein the outer wall of the front end of the medical stomach tube is provided with a first low-pressure cuff and a second low-pressure cuff, the other end of the stomach tube is provided with two air ducts, the end of the air ducts are respectively provided with a first air piston and a second air piston, the first air piston is communicated with the first low-pressure cuff through the air duct, and the second air piston is communicated with the second low-pressure cuff through the air duct. The utility model has the advantages of that the two low-pressure cuffs can be alternatively charged to enclose the interval between the outer wall of the stomach tube and the inner wall of the food pipe, thereby preventing inspiratory regurgitation and having convenient operation and safety.
Description
Technical field:
This utility model relates to the mankind life article, relates in particular to medical apparatus and instruments, particularly Medical gastric canal, and concrete is a kind of pre-anti-error suction type stomach tube.
Background technology:
Many emergency call salving patients are full gastropathy people, and in the emergency call salving process, gastric content, gastric acid etc. can backflow to pars oralis pharyngis, cause mistake to be inhaled easily, and in case mistake takes place inhale, can cause suctions (chemistry) property pneumonia, in the time of seriously with threat to life.Particularly need the full gastropathy people of general anesthesia induction that performs the operation, realize owing to temporarily suppress clear-headed, the danger that mistake is inhaled gastric content is bigger.In the prior art, the way of clinical prevention aspiration pneumonitis has the common Medical gastric canal sucking-off gastric content of insertion or uses H
2Adopt conscious intubation when receptor blocking agent or general anesthesia induction or push forms such as cricoid cartilage with pointing to the esophagus direction when backflowing.But, owing to there is a potential space between stomach tube outer wall and esophagus inwall, common Medical gastric canal is difficult to complete sucking-off gastric content after inserting, and remaining gastric content, gastric acid can backflow to pars oralis pharyngis along the space between stomach tube outer wall and the esophagus inwall, and causes mistake to be inhaled.And application H
2The method of receptor blocking agent can only reduce gastric acid, and can't effectively stop and backflow.Adopt the method for conscious intubation that patient is stimulated greatly, cause more complication easily, simultaneously, potential space still exists between stomach tube outer wall and esophagus inwall, and still wrong suction is dangerous.And, be difficult to hold action moment with the method that finger is pushed cricoid cartilage to the esophagus direction, can't eliminate mistake fully and inhale dangerous.
Summary of the invention:
The purpose of this utility model provides a kind of pre-anti-error suction type stomach tube, and described this pre-anti-error suction type stomach tube will solve in the prior art owing to the technical problem that exists the gap to cause mistake to inhale gastric content between stomach tube outer wall and the esophagus inwall.
This pre-anti-error suction type stomach tube of the present utility model is made of a Medical gastric canal, wherein, be arranged with one first low gland capsule and one second low gland capsule on the front end outer tube wall of described Medical gastric canal, the described first low gland capsule is communicated with one first inflating catheter, the described second low gland capsule is communicated with one second inflating catheter, described first inflating catheter and second inflating catheter all are arranged in the Medical gastric canal, the end of first inflating catheter and second inflating catheter separates with the end of Medical gastric canal, and the end of first inflating catheter and second inflating catheter is respectively arranged with the first inflation piston and the second inflation piston.
Further, the front end of the described first low gland capsule and described Medical gastric canal is at a distance of 29.5cm.
Further, the front end of the described second low gland capsule and described Medical gastric canal is at a distance of 32.5cm.
Further, the described first low gland capsule and the described second low gland capsule length are 2.5cm, and the inflated diameter of the first low gland capsule and the second low gland capsule is between 2.5～3.0cm.
Further, the blowing pressure of the first low gland capsule and the second low gland capsule inside is less than 25mmHg.
Operation principle of the present utility model is: the general long 25～30cm of adult's esophagus, from front tooth to the esophagus opening, the adult is about 15cm, from front tooth to esophagus end is 40～45cm, the diameter of adult's esophagus tube chamber is 1.5～2.5cm, esophagus has certain dilatancy, and its diameter can reach more than the 3.0cm when expanding fully.Medical gastric canal generally is about 120cm, via intranasal application is inserted stomach tube and generally is inserted into about 60cm, according to the stomach tube scale mark, make the first low gland capsule be positioned at the introitus oesophagi place, the first inflation piston through the first low gland capsule injects 20～25ml air then, make that diameter is 2.5～3.0cm behind first sleeve bag gas-filling, just in time block the space between stomach tube outer wall and esophagus inwall, can try to lead stomach tube gently after the inflation, can not be pulled as stomach tube, correct position is described, after 6～8 hours, through the second inflation piston injection, the 20～25ml of second low gland capsule air, the air in the first inflation piston is found time the first low cover capsule is alternately inflated then, bleed and effectively to prevent long-time inflation compression mucous membrane of esophagus to cause its rotten to the corn necrosis.Pressure is less than 25mmHg behind the first low gland capsule and the second low pressure sleeve bag gas-filling, can Secure Application in clinical, can effectively prevent the space of gastric content through between stomach tube outer wall and esophagus inwall to backflow and cause the danger of mistake suction.
This utility model and prior art contrast, and its effect is actively with tangible.This utility model is provided with two low gland capsules on Medical gastric canal, by to the alternately inflation of two low gland capsules, solved a difficult problem that has the gap between stomach tube outer wall and the esophagus inwall, causes mistake to be inhaled easily, and is easy to operate, safe and effective.
