The invention discloses a disposable nasogastric tube comprising a catheter, an adapter, a connecting plug, a guide wire and a mark line. The adapter is arranged at the upper end of the catheter, the connecting plug is connected with the connecting plug in an inserted manner, the guide wire is fixed at the bottom of the connecting plug, and the mark line is arranged on the catheter. The guide wire penetrates the catheter and extends to the bottom of the same, two sides of the lower end of the catheter are provided with a plurality of liquid outlets, a port at the lower end of the catheter is provided with a circular arc end cap, and scales are arranged on the side edge of the mark line. The disposable nasogastric tube is convenient to use; the catheter small in resistance can be inserted smoothly and is less prone to causing discomfort to patients, the catheter has good histocompatibility, so that the disposable nasogastric tube can stay in the stomach for a long time.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a disposable nasogastric tube. Background technique [0002] The nasogastric tube is inserted into the stomach from the patient's nasal cavity or mouth, and liquid food is fed into the stomach of the patient who cannot eat normally, and gastric juice can also be extracted from the stomach for testing. [0003] However, the existing single-use nasogastric tube has the following defects: (1) it is inconvenient to use when it is inserted into the stomach, the resistance of the catheter is large, and it is not smooth enough, which is likely to cause strong discomfort to the patient; (2) ) does not have good tissue compatibility and cannot be placed in the stomach for a long time. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a disposable nasogastric tube, which is very convenient to use, the resistance of the catheter i...
