Description
Technical field
The present invention relates to technical field of medical instruments, the gastroscope sleeve pipe that the anti-mistake of backflowing is inhaled when being a kind of full gastropathy people's gastroscopy.
Background technology
Gastroscopy is an inspection item common in the present hospital, and its effect is to check the upper digestive tract situation in order to look at straight down, can also carry out some treatments.This inspection is a sophisticated inspection item.The general long 25～30cm of adult's esophagus to the esophagus end, is 40～45cm from front tooth, and adult's esophagus lumen diameter is 15～25mm, and esophagus has certain dilatancy, and diameter can reach about 30mm when expanding fully.Gastroscope typically has a diameter from 12mm, and the gastroscopy degree of depth generally can not surpass 100cm.Because the gastroscopy meeting is brought out those who are investigated and is vomitted action, and need in digestive tract, to inflate the vomiting that also can cause nausea in the checking process, therefore before gastroscopy, require those who are investigated's gastric not have content usually, otherwise gastric content can be by the entrance cavity that backflows of the space between esophagus and gastroscope, the oral cavity is again esophagus and air flue common open, return effusive gastric content and might be sucked air flue by mistake, suffocate thereby can cause suction (chemistry) property pneumonia or cause, when serious with threat to life.For first-aid patients; all be to be in full stomach state usually during rescue; the mistake that occurs easily when such patient is carried out gastroscopy backflowing is inhaled; especially in digestive tract hemorrhage patient (being considered to a kind of of full gastropathy people); may cause mind to change owing to lose blood; it is undesired that throat such as coughs, swallows at the guarding reflex function, and it is bigger that the mistake of backflowing is inhaled probability.At present comprise and insert the stomach tube drain in advance for reducing the backflow way of mistake air draught danger of full gastropathy people gastroscopy clinically, use medicine to reduce gastric secretions, delay the review time etc.But it is unconspicuous that said method acts on when gastric content continues to exist, as long as there is gastric content, just can not avoid fully backflowing, so just can not eliminate the mistake air draught danger of backflowing in the full gastropathy people gastroscopy process fully.Full gastropathy people carries out gastroscopic risk makes gastroscopy utilization scope be subjected to certain restriction.
Summary of the invention
The gastroscope sleeve pipe that the anti-mistake of backflowing is inhaled when the purpose of this invention is to provide a kind of full gastropathy people's gastroscopy.
The present invention shows that by the gentle end finger of gas tube of sleeve pipe, sleeve pipe clip, cardia air bag, esophagus air bag, two air bags air bag constitutes.Sleeve pipe is hollow cylindrical, and the external diameter coupling of internal diameter and gastroscope is so that be enclosed within outside the gastroscope; Its top is connected with the sleeve pipe clip, and the sleeve pipe clip can be wire or other shapes, and the biopsy forceps of available gastroscope is clamped, so that cannula tip is fixed in the top of gastroscope when inserting esophagus, tube ends has a finger ring shape projection, and it is a gripper rings, and sleeve pipe grips and prevent slippage when being convenient to operate; The cardia air bag is attached to the outer wall of sleeve pipe head, and the internal diameter of the big sub-esophagus of inflation back maximum gauge is used to stop up the cardia of stomach and esophagus boundary, to prevent that gastric content is by the entrance cavity that backflows of the space between esophagus and gastroscope; The esophagus air bag is attached to the outer wall of sleeve body, and in a tubular form, maximum outside diameter is slightly larger than the internal diameter of esophagus after the inflation, utilizes the frictional force fixed sleeving between itself and the esophageal wall and prevents the displacement of cardia air bag; Two airbag inflation pipes are attached at telescopic outer wall, front end joins and communicates with cardia air bag, esophagus air bag respectively, tail end is free on outside the telescopic tail end and by air pressure indication sacculus and links to each other with charge valve, be used for to airbag aeration or venting, can understand the airbag aeration degree by air pressure indication sacculus.
During use, the gastroscope sleeve pipe is placed on the gastroscope, clamp the sleeve pipe clip of cannula tip with the biopsy forceps of gastroscope, with gastroscope by the oral cavity after esophagus inserts gastric, by airbag inflation pipe to the cardia airbag aeration, again gastroscope is pulled back backward together with the gastroscope sleeve pipe, make the cardia air bag seal cardia, make it be fixed in esophagus by another airbag inflation pipe to the esophagus airbag aeration then, at last biopsy forceps is unclamped from the sleeve pipe clip, gastroscope can move forward and backward, and carries out gastroscopy routinely.Check and finish, by airbag inflation pipe the gas in cardia air bag and the esophagus air bag is extracted respectively, routinely gastroscope is together extracted out together with the gastroscope sleeve pipe again.
For the unclear patient in digestive tract hemorrhage position, if the bleeding part at esophagus, of the present invention inserting can be played interim hemostatic effect by the corresponding petechia of esophagus balloon tamponade.Need if rescue, sleeve pipe of the present invention can also play the gastric drainage similar to stomach tube.
The present invention is simple in structure, and is with low cost, easy to operate during use, can effectively solve the mistake air draught danger problem of backflowing in the full gastropathy people gastroscopy process.
