Oral nutrition tube

Abstract

The invention provides an oral nutrition tube. The oral nutrition tube comprises a tube body, wherein a food inlet is arranged at the head end of the tube body; a food outlet hole is arranged on the end wall of the tube body; a silica gel guide head is integrally packaged at the end of the tube body; the tail end of the silica gel guide head is provided with a smooth spherical crown-shaped outer surface, and the hardness of the silica gel guide head is smaller than that of the tube body; the tail end of the tube body is encapsulated by a silica gel guide head, and the hardness of the silica gel guide head is smaller than the hardness of the tube body, and the tail end of the silica gel guide head is a spherical crown-shaped outer surface; when in use, the silica gel guide head guides the tube body into the human body, and when the silica gel guide head passes through the throat part, the spherical crown-shaped outer surface of the silica gel guide head contacts with the throat; and thesilica gel guide head material is relatively soft, and certain bending deformation will occur, so that the silica gel guide head can smoothly adhere to the wall and pass through the throat, thereby facilitating the intubation operation. Due to the smooth exterior and soft material of the silica gel guide head, the harm to human body is small, and the comfort degree of the patient is improved.

Description

technical field [0001] The invention relates to an oral nutrition tube. Background technique [0002] The structure of the current oral nutrition tube is shown in the utility model patent whose authorized announcement number is CN202892454U. This utility model patent discloses a new type of oral nutrition gastric tube. The food inlet is connected with a needle tube joint, and the needle tube joint is connected with an end cover, which can ensure the cleanliness of the needle tube joint when the needle tube joint is not in use. On the tube wall at the end of the tube body, there is a through hole (that is, the food outflow hole) that runs through the inside and outside of the tube body. The through hole is an elliptical hole. It can improve the passing capacity of the through hole when injecting food with larger particles. Moreover, a tooth pad is sheathed on the outer tube wall of the tube body close to the needle tube joint, and the rear end of the tooth pad is provided w...

AI Technical Summary

Problems solved by technology

When the oral nutrition tube is inserted into the human body from the outside to the inside, because the material of the tube body and the mask body is relatively hard and the outer surface is rough, during the intubation process, especially when passing through the throat, it is not easy for the mask body to come into contact with the throat wall. Bending occurs, unable to stick to the wall for redirection and movement, increasing the difficulty of intubation

Moreover, due to the rough outer surface of the cover and the high friction with the human body, the comfort of the patient is greatly reduced, and the resistance during intubation also increases correspondingly, further increasing the difficulty of intubation
