Abstract
The utility model discloses a gastric canal conduit tube which belongs to the technical field of the medical appliance. The gastric canal conduit tube is composed of a conduit tube (1) and pinch pieces (2) and is characterized in that the appearance of the conduit tube (1) is provided with a physiological radian for anatomizing the nose, the pharynx and the oral cavity, the inside diameter is matched with the outside diameter of the gastric canal, a scale mark is arranged on the outer wall of the conduit tube, two V-shaped groove marks (3) which can be torn are symmetrically arranged on the inner wall of the conduit tube, the front end of the conduit tube adopts a smooth opening, and the pinch pieces (2) are respectively arranged at both sides of the V-shaped groove marks (3) arranged at the rear end. The utility model has the advantages that the structure is simple and the operation is convenient; before the flexible gastric canal is inserted, a man-made channel is built between the nasal cavity and the esophagus through the hard gastric canal conduit tube to ensure the flexible gastric canal to naturally enter the esophagus and the gastral cavity, and the success ratio of inserting the gastric canal can be greatly enhanced, thereby the utility model is especially suitable for unconscious patients suffering from coma or assuage and patients receiving trachea sleeve mechanical ventilation.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind ofly is used for the gastric canal that stomach tube is inserted clinically.
Background technology
At present, medical and nursing work person mainly is the softish stomach tube via intranasal application of quality to be entered the oral cavity enter gastral cavity through esophagus again for the patient places stomach tube, and this section is the difficult point of gastric tube placement from the oral cavity to the esophageal orifice.Because anatomical structure complexity in the oral cavity is added stomach tube quality softness, so be difficult to enter esophagus according to predetermined direction, in most cases is difficult to enter in the oral cavity inside turn.Can also cooperate with on one's own initiative by the patient clear-headed cooperation patient clinically and do swallowing act stomach tube is swallowed esophagus, enter gastral cavity at last.Yet to uncooperative patient, for example stupor or calm unconscious patients and the critical patient or the anesthesia patient of tracheal intubation row mechanical ventilation, it but is a difficult problem that the via intranasal application stomach tube is inserted esophagus, mainly is now to adopt seal wire, strengthen stomach tube toughness, wish to make a forcible entry into esophagus.But find that in clinical for the patient of tracheal intubation row mechanical ventilation, the method sometimes still is difficult to send into esophagus.Another method is to use laryngoscope to send into esophagus with intubating forceps clamp stomach tube head under photopic vision, but because endotracheal tube has occupied part space, oral cavity, operation is difficulty relatively, and easily mucous membrane tissues such as oral cavity is caused damage.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and makes stomach tube insert the gastric canal of usefulness easily in clinical, inserts the success rate that especially difficult stomach tube is inserted to improve stomach tube.
The purpose of this utility model is achieved in that this gastric canal is by conduit with pinch sheet and form, the conduit profile has the physiologic radian that dissect in the nasopharynx oral cavity, internal diameter and stomach tube external diameter are complementary, outer wall is provided with scale mark, on the inwall symmetric be provided with two can be for " V " shape flute mark of tearing, catheter proximal end is slick and sly opening, and shape flute mark both sides, rear end " V " are respectively equipped with pinches sheet, and pinching has finger hole on the sheet.Gastric canal can adopt has flexibility, and the quality medical material hard than stomach tube make, and for example selects polrvinyl chloride (PVC) material commonly used to make.
During use, earlier gastric canal is inserted from patient's nasal cavity or oral cavity,, therefore, insert also accessible because the gastric canal quality is harder.So between nasal cavity and esophagus, set up an artificial nest, then the stomach tube of flexibility inserted esophagus in conduit, until entering gastral cavity.Enter the region of interest of gastral cavity when stomach tube after, finger is inserted in the finger hole of pinching above the sheet, to the both sides tearing, gastric canal is torn along " V " shape flute mark, and gastric canal limit torn edges moves back, until withdrawing from fully, and all torn in two, success with put the stomach tube that stays and separate.
Advantage of the present utility model: simple in structure, use easy to operate, before inserting flexible stomach tube, use the gastric canal of hard between nasal cavity and esophagus, to set up an artificial channel earlier, make flexible stomach tube enter esophagus naturally and enter gastral cavity through this pipeline, the success rate that stomach tube is inserted be can improve greatly, unconscious patients such as stupor, calmness and circulation of qi promoting cannula patients with mechanical ventilation are particularly suitable for.
Description of drawings
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is looked enlarged drawing for the left side of accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing 1, the utility model is described in further detail for accompanying drawing 2: this gastric canal is by conduit 1 and pinch sheet 2 and form, conduit 1 profile has the physiologic radian that dissect in the nasopharynx oral cavity, internal diameter and stomach tube external diameter are complementary, outer wall is provided with scale mark, on the inwall symmetric be provided with two can be for " V " shape flute mark 3 of tearing, conduit 1 front end is slick and sly opening, and shape flute mark 3 both sides, rear end " V " are respectively equipped with pinches sheet 2, and pinching on the sheet 2 has finger hole.
Claims (2)
1. gastric canal, by conduit (1) with pinch sheet (2) and form, it is characterized in that conduit (1) profile has the physiologic radian that dissect in the nasopharynx oral cavity, internal diameter and stomach tube external diameter are complementary, outer wall is provided with scale mark, on the inwall symmetric be provided with two can be for " V " shape flute mark (3) of tearing, conduit (1) front end is slick and sly opening, rear end " V " shape flute mark (3) both sides are respectively equipped with pinches sheet (2).
2. gastric canal according to claim 1 is characterized in that pinching on the sheet (2) finger hole is arranged.
