Abstract
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
The present invention relates to medical instruments field, particularly relate to a kind of disposable use nasogastric tube.
Background technology
Insert the stomach in nasal cavity or oral cavity from patient when nasogastric tube uses, sends into the food of liquid class in the stomach to the patient that can not normally take food, and also can extract gastric juice from stomach and chemically examine.
Yet existing disposable use nasogastric tube has following defective: (1) uses inconvenience interting when entering in the stomach, and the resistance of conduit is large, and is smooth and easy not, easily causes stronger sense of discomfort to the patient; (2) do not possess good histocompatibility, can not the long period place stomach.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of disposable use nasogastric tube, and very convenient to use, the resistance of conduit is little, conduit is more smooth and easy during insertion, be difficult for causing sense of discomfort to the patient, possess good histocompatibility, can the long period place stomach.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of disposable use nasogastric tube is provided, comprise: conduit, be arranged on conduit upper end joint, be plugged in connecting pin in the joint, be fixed in the seal wire of connecting pin lower end and be arranged at supravasal developing line, described seal wire is through described conduit and extend to the bottom of conduit, both sides, described conduit lower end all be provided with a plurality of liquid outlets, also be provided with the circular arc plug in the port of the lower end of described conduit, be provided with scale on the side of described developing line.
In a preferred embodiment of the present invention, described conduit is made by polyurethane.
