Nasogastric tube with double-tube chamber

Abstract

The invention discloses a nasogastric tube with a double-tube cavity, which comprises a perfusion tube cavity, and the inside of the tube body is also provided with a guide wire tube cavity which allows a guide wire to insert in, wherein the tail end of the guide wire tube cavity is a blind end, and the diameter of the guide wire tube cavity is equivalent to that of the guide wire. The nasogastric tube has the advantages that: 1, the problem that the guide wire is directly contacted with exudates in vivo is effectively solved so as to reduce the infection probability; and 2, the diameter of the guide wire tube cavity is made to be equivalent to that of the guide wire so as to greatly increase the strength of the nasogastric tube body, and ensure that the nasogastric tube can be inserted into the body of a patient smoothly and positioned accurately, and the operation can be completed by once insertion so as to avoid repeated operation, and reduce the pain of the patient.

Description

Technical field: [0001] The invention specifically refers to a nasogastric tube. Background technique: [0002] The traditional nasogastric tube is designed with only one infusion lumen. Before inserting into the patient’s body, the guide wire needs to be inserted into the infusion lumen. During the process of inserting the guide wire into the infusion lumen, normal saline must be injected from time to time. Carry out lubrication and disinfection. After being inserted into the patient's body, since the guide wire is placed in the infusion tube lumen, it is in direct contact with the secretion of organs in the body. If the disinfection is not good, it is easy to cause bacterial infection; The guide wire is much larger, and the guide wire is easily twisted in the lumen of the infusion tube, resulting in insufficient strength of the nasogastric tube body. When the nasogastric tube is inserted into the human body, the tube body is also easily twisted, resulting in The insertion...

Problems solved by technology

[0002] The traditional nasogastric tube is designed with only one infusion lumen. Before inserting into the patient’s body, the guide wire needs to be inserted into the infusion lumen. During the process of inserting the guide wire into the infusion lumen, normal saline must be injected from time to time. Carry out lubrication and disinfection. After being inserted into the patient's body, since the guide wire is placed in the infusion tube lumen, it is in direct contact with the secretion of organs in the body. If the disinfection is not good, it is easy to cause bacterial infection; The guide wire is much larger, and the guide wire is easily twisted in the lumen of the infusion tube, resulting in insufficient strength of the nasogastric tube body. When the nasogastric tube is inserted into the human body, the tube body is also easily twisted, resulting in The insertion depth error of the tube is relatively large, and it is difficult to determine whether the tube body has reached the stomach. If the tube body does not reach the stomach as required, the insertion action must be continued, which will increase the pain of the patient.
