Abstract

The utility model relates to a double-chamber ball type stomach tube which belongs to a medical appliance. The utility model is produced by emulsion silication for medical application; the utility model is composed of a food entering cavity, a water injection cavity, a catheter, a saccule and three side holes. The utility model is characterized in that after the stomach tube is inserted, water is injected into the saccule through the water injection cavity to enable the saccule to prevent the stomach tube from being pulled out; foods can be led into a stomach or gastric contents can be discharged through the food entering cavity, the catheter and the three side holes. The double-chamber ball type stomach tube has the advantages of softness, comfort, etc. Moreover, the utility model is easy to accept by patients, the utility model does not need to be fixed by rubberized fabric, repeated tube insertion can be avoided and pain of the patients can be relieved.

Description

A kind of two-chamber ball formula stomach tube

This utility model belongs to medical instruments.

Be single chamber stomach tube that medical grade rubber is made with stomach tube now, quality is harder, mainly forms by annotating food chamber and three side openings, by three side openings, injects food or suction gastric content from annotating the food intracavity.After this stomach tube inserts stomach, because stomach tube activity space in inserting the road is relatively large, need with immobilization with adhesive tape at place, nostril or buccal, clinical intubate stimulates nose, pharyngeal generation easily, senses of discomfort such as that patient has is nauseating, vomiting.For nasal feeding of long-term placement stomach tube and the forward and backward patient who needs gastrointestinal decompression of surgery art, because of movable, nauseating or not firm because of the rubberized fabric adhere that uses, stomach tube is very easily deviate from, and so not only causes suffering to patient, and has increased nursing staff's workload.

The purpose of this utility model is, provides a kind of two-chamber ball formula stomach tube, patient's discomfort reaction when it not only can reduce or eliminate intubate, and need not to use immobilization with adhesive tape, avoided stomach tube to deviate from, and can be convenient to use any patient of stomach tube.

This utility model two-chamber ball formula stomach tube is made with the medical latex silication, mainly is made up of feed chamber, water-injecting cavity, conduit, sacculus and three feed side openings.Be characterized in: the feed chamber is the pipe that an entrance point diameter is made by the medical latex silication greater than port of export diameter, its port of export links to each other with conduit top, the conduit bottom has three side openings in the equidistant and no longer same plane, have inner groovy on the conduit upper outside wall, form sacculus with the outer moccasin of the rubber-like that is wrapped in appearance around conduit.Intake antrum is the soft pipe that a water inlet end has water filling ball chuck and water injection hole, and its outlet tube wall is integrated on conduit top with feed chamber exit wall, communicates with sacculus.

In the clinical practice, when when gastric injects food, at first measure intubation length, insert then and insert a little behind the Len req again, extract normal saline with the pin control according to patient, by water-injecting cavity to the sacculus water filling, because of sacculus is in appetite cardia the inside, after water filling was arrived to a certain degree, expansible sacculus was blocked by the appetite cardia, has stoped stomach tube ground to be deviate from, inject food by annotating the food chamber this moment, and food enters in the stomach by three side openings.

When the suction gastric content, the chamber entrance point applies negative pressure on the feed,, gastric content is discharged by the feed chamber gastric content inspiration conduit by three side openings.

Because normal person's esophagus is a flesh tube chamber, the about 1.5-3cm of diameter, the appetite cardia under normal circumstances is in closure state, and normal esophageal is expansible to 3-4cm, generally is no more than 5cm.Therefore, the double-cavity stomach tube of this utility model, in sacculus after the water filling diameter generally below 5cm.Patient can not produce nauseating, and stomach tube also is difficult for deviating from the time of firmly.
