One end of the silicone tube body 1 provided with the plug 2 is inserted into the nasal cavity of a patient, and then is inserted into the stomach through the oral cavity and the esophagus of the patient in sequence until the air bag 4 passes through the cardia of the stomach; then, opening an inflation valve to inflate the air bag 4 by means of the air duct 7 through the third blind hole 15 and the vent hole 16, and then pulling the silicone tube body 1 outwards to show that the air bag 4 reaches the cardia gate after encountering resistance; thereafter, the balloon 4 is continuously inflated to adjust to the appropriate pressure, thereby gradually deforming the silicone tube body 1 but still allowing the nutrient solution to pass through, so that the outer walls of both band-shaped conductive coatings 5 are in direct contact and in close proximity to the cardiac sphincter 8.
The nutrient solution is introduced into the silica gel tube body 1 to enter the stomach of a patient through each liquid outlet hole 17, so that nutrient substances can be conveyed into the stomach of the patient with poor consciousness after brain trauma, cerebral apoplexy, brain tumor and brain degenerative diseases, dysphagia caused by brain stem dysfunction or intestinal nutrition after chest and abdomen operation, but the stomach has the problems of insufficient gastric motility, relaxation of gastric emptying, gastroparesis, disturbance of peristaltic rhythm of the stomach and the like because the patient cannot eat by himself, so that the nutrient solution conveyed into the stomach of the patient can not be digested quickly, and further the reflux of the gastric contents and the pulmonary infection caused by the aspiration of air passages can be easily caused.
The invention is characterized in that: after nutrient solution is introduced into the stomach of a patient, the gastric motility detector is started to enable two data acquisition ports on the gastric motility detector to be respectively connected with the two electrode plates 3 by means of the two leads 6, and then the gastric motility detector automatically acquires gastric motility data of the patient (the prior art); starting the electric pulse generator and setting the stimulation parameters of the electric pulse generator according to the gastric power data acquired by the gastric power detector, wherein the stimulation parameters comprise stimulation intensity, frequency, pulse width and the like; then, the electric pulse generator alternately sends electric pulse signals to the two electrode plates 3 according to a certain frequency, and the electric pulse signals can perform intermittent electric stimulation on the cardiac sphincter 8 between the two electrode plates 3; since the cardia is the initial stage of the greater curvature of the stomach, the interior of the cardia is the pacing site of the stomach, and intermittent electrical stimulation of the cardiac sphincter muscle 8 can effectively promote the formation of gastric peristalsis, thereby promoting the recovery of gastric emptying capacity.
The invention adopts a noninvasive technology method to directly perform contact type electric stimulation on the gastric pacing point of the cardiac part, and the effect is far better than the in-vitro acupuncture point stimulation; after the use is completed, the two electrode plates 3 and the two strip-shaped conductive coatings 5 can leave the stomach of the patient along with the silicone tube body 1 by pumping out the gas in the air bag 4, so that the general anesthesia operation wound of the implanted electric stimulator is avoided, and the implanted electric stimulator is more easily accepted by the patient and family members.
