Description
Technical Field
The utility model relates to a medical instrument, concretely relates to concertina type nasogastric tube.
Background
The nasogastric tube is inserted from the nostril, passes through the pharynx, reaches the stomach through the esophagus, is mainly used for sucking gastric juice, and can also be used for injecting liquid into the stomach to provide necessary food and nutrition for a patient.
In clinical application, because the exposed length of the nasogastric tube is too long, the exposed part is easy to grasp by the hand of a patient, and the exposed part is easy to be caught by objects, so that the nasogastric tube is unplanned to be pulled out. This not only can cause the damage to patient's nasal mucosa, still can lead to the state of an illness to aggravate simultaneously, and repeated putting the pipe still can increase patient's misery and economic burden, increases nurse's work, has the nursing hidden danger.
Therefore, a novel nasogastric tube is needed, and the exposed length of the nasogastric tube can be adjusted according to requirements, so that the occurrence of unplanned tube drawing is reduced.
Disclosure of Invention
In order to solve the problems, the utility model provides a telescopic nasogastric tube.
The technical scheme of the utility model is that: a telescopic nasogastric tube comprises an internal tube, wherein an external tube is fixedly connected with the rear end of the internal tube, and the external tube is a telescopic tube; a receiving barrel is arranged at the joint of the body inner tube and the body outer tube, and the inner diameter of the receiving barrel is larger than the outer diameter of the body outer tube; the opening of the containing barrel faces the external body tube, and the retracted length of the external body tube is smaller than that of the containing barrel; the rear end of the outer body tube is provided with a fixed cover; the front part of the fixed cover is provided with a first plug matched with the inner diameter of the outer tube, the middle part of the fixed cover is provided with a second plug matched with the inner diameter of the storage barrel, and the rear part of the fixed cover is provided with a detaching disc.
Furthermore, the fixed cover is fixedly connected to the rear end of the body outer tube through a connecting wire.
Furthermore, a placing groove for containing the connecting wires is arranged in the containing barrel.
The telescopic nasogastric tube of the utility model has simple structure and convenient use, and can adjust the exposed length of the nasogastric tube according to the requirement; the storage barrel and the fixing cover are designed, so that the external tube can be compressed and stored when not used, the exposed length of the nasogastric tube is reduced, and the occurrence of unplanned tube drawing is reduced; simultaneously, the storage barrel can prevent the compressed nasogastric tube from entering the nasal cavity completely.
