Multifunctional nasogastric intestinal composite canal

Abstract

The invention discloses a multifunctional nasogastric intestinal composite canal. The tube comprises an upper portion tube body and a lower portion tube body, the upper portion tube body comprises a first tube cavity and a second tube cavity, the second tube cavity is communicated with the lower portion tube body, the lower portion tube body is an opened tube body which is provided with a circulating port, the lower tube body is a spiral tube body, a pressure reduction side hole used for reducing the pressure of the stomach is formed in the side, close to the side of the lower portion tube body, of the second tube cavity, the tail end of the lower portion tube body is provided with a steering lubricating head, and lubricating coated layers are arranged on the outer surfaces of the upper portion tube body and the lower portion tube body. The invention provides the multifunctional nasogastric intestinal composite canal, compared with the prior art, the position of an intestinal canal canbe conveniently determined to prevent the risks and safety hazards of patients and medical workers exposing in radiation, the blockage of intestinal passages can be effectively prevented, and the discomfort feeling of the patients can be significantly relieved.

Description

technical field [0001] The present application relates to the technical field of medical devices, and more specifically, relates to a multifunctional nasogastric compound tube. Background technique [0002] In recent years, with the development of nutritional support theory and practice and the deepening of understanding of gastrointestinal function, modern nutrition theory and practice have attached great importance to the role of enteral nutrition (EN) in nutritional support treatment, maintenance of intestinal mucosal barrier, intestinal Because of its special role in tract motility and secretion function, enteral nutrition support therapy has been widely used in the world. When choosing a nutritional method, EN should be the first choice when the intestinal tract is functional or partially functional, which has become the consensus of many clinicians. Prioritizing EN for nutritional support in critically ill patients has been gradually accepted and applied clinically by...

Problems solved by technology

[0003] However, the existing ordinary intestinal tube is only used for enteral nutrition, and an additional gastric tube needs to be placed during gastric decompression, which increases the pain and economic burden of the patient; secondly, due to the narrow structure of the human body's pylorus, it is difficult to place the intestinal tube, and generally requires Relying on the intestinal tube to slide through structures such as the pylorus, it often takes more than several hours, and the cycle is long; even, a gastroscope is needed to assist in the insertion of the tube. After the tube is placed, X-rays and other methods are required to confirm the position of the intestinal tube, which increases the burden on patients and medical staff. The risks and hazards of personnel exposure to radiation, intestinal blockage and difficulty in catheterization are two major problems that plague the clinical use of intestinal tubes at this stage
