Multi-chamber slidable gastric tube

Abstract

The invention discloses a multi-chamber slideable gastric tube. The multi-chamber slideable gastric tube includes a gastric tube and a phlegm suction catheter; a ball bag is fixedly connected to the periphery of the head of the gastric tube; the head of the gastric tube is provided with a gastric tube opening, a first inflation channel is provided in the gastric tube, the gas outlet of the inflation channel is communicated with the ball bag, a one-way valve is provided at the gas inlet of the first inflation channel, a gastric tube joint is provided at the end of the gastric tube, and a filterscreen is arranged in the inner chamber of the gastric tube joint; a gasbag is fixedly connected to the periphery of the head of the phlegm suction catheter, a gastric tube channel, a second inflation channel, a cleaning channel, an oxygen suction channel and a phlegm suction channel are arranged in the phlegm suction catheter, the head of the second inflation channel is communicated with the gasbag, the gastric tube slides in the gastric tube channel, the cleaning channel is communicated with the phlegm suction channel trough a cleaning hole, the oxygen suction channel is communicated with an oxygen suction hole, the phlegm suction channel is communicated with a phlegm suction hole, the cleaning hole is located at the downstream of the phlegm suction hole, a one-way valve is arranged inthe phlegm suction channel, the one-way valve is located between the phlegm suction hole and the cleaning hole, and a regulating valve is arranged at the end of the second inflation channel. The multi-chamber slideable gastric tube has the advantages of realization multi-time use by one-time intubation, loosening prevention, reduction of pipeline blockage, and prevention of suffocation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multi-cavity slidable gastric tube. Background technique [0002] For critically ill patients, post-operative patients, patients with disturbance of consciousness and swallowing disorders, nasogastric feeding tube is the main medical tool for feeding liquid diet in hospitals at present. Sputum tube. At the same time, most of the bedridden patients are complicated with collapsing pneumonia and need to clean up the respiratory tract sputum. At present, nasal feeding or sputum suction for patients needs to be performed at intervals. Switching between the sputum suction tube and gastric tube for insertion increases the number of patients The pain of repeated intubation. Contents of the invention [0003] The invention aims to provide a multi-cavity slidable gastric tube, which can be used for multiple times with one intubation, prevents loosening, reduces pipeline blockage, and pr...
