Background

After an operation is performed on a patient, intestinal nutrition needs to be maintained, so that a nose-intestine tube needs to be placed in the operation, the nose-intestine tube cannot be placed in the general anesthesia patient through swallowing action and matched with the nose-intestine tube, an insertion part of the nose-intestine tube is often bent and folded at the oropharynx and the laryngopharynx, and cannot enter the esophagus, although a steel wire is arranged in the nose-intestine tube, certain difficulty still exists when the nose-intestine tube is simply placed in clinical work, the first success rate is low, the mucosa of the laryngopharynx is damaged easily due to the reciprocating operation, and the pain of the patient is increased; some of the current clinical practice adopts guide tubes, the nose intestinal tube is inserted into the guide tube, the guide tube is used for being inserted into the esophagus, and the existing guide tube cannot exit from a funnel joint with a larger tail end of the nose intestinal tube after the guide operation is completed, so that the nose intestinal tube is inconvenient to use.

Disclosure of Invention

Aiming at the existing problems, the utility model provides a tearable guide sleeve, the guide sleeve is sleeved outside a nose-intestine tube, so that the nose-intestine tube can be guided to smoothly pass through the oropharynx or the laryngopharynx, the nose-intestine tube is convenient to insert into the esophagus, and the nose-intestine tube is convenient to insert and pull in the guide sleeve to adjust the depth, so that the pain of a patient is reduced; the guide sleeve can be torn and separated, so that the guide sleeve can be conveniently withdrawn from the nose intestine after the nose intestine is inserted into the esophagus, the guide sleeve is convenient to use, and the problems in the background technology can be effectively solved.

In order to solve the problems, the utility model adopts the following technical scheme:

the tearable guide sleeve comprises a guide sleeve, wherein the insertion end of the guide sleeve is a smooth tip inclined surface, and the side surface of the guide sleeve can be torn and separated along the central axis direction.

As still further aspects of the utility model: the side surface of the guide sleeve is provided with a tearing strip along the central axis direction.

As still further aspects of the utility model: the two tearing strips are symmetrically arranged at the center of the guide sleeve, and the guide sleeve is divided into two half sleeves after the tearing strips are torn.

As still further aspects of the utility model: the proximal end of the tearing strip is provided with a tearing handle which is connected into a whole.

As still further aspects of the utility model: an easy-to-tear line is arranged between the two sides of the tearing strip and the guide sleeve.

As still further aspects of the utility model: the proximal ends of the two half sleeves are fixedly connected with operation handles.

As still further aspects of the utility model: the inner wall and the outer wall of the guide sleeve are smooth surfaces, and the inner walls of the near ports of the two half sleeves are fixedly connected with rubber arc pads.

As still further aspects of the utility model: the guide sleeve is a silica gel tube.

Compared with the prior art, the utility model has the beneficial effects that: the guide sleeve is sleeved outside the nose intestine, so that the nose intestine can be guided to smoothly pass through the oropharynx or the laryngopharynx, the nose intestine can be conveniently inserted into the esophagus, the nose intestine can be conveniently inserted into the guide sleeve to adjust the depth, and the pain of a patient is reduced; the guide sleeve can be torn and separated, so that the guide sleeve can be conveniently withdrawn from the nose intestine after the nose intestine is inserted into the esophagus, and the use is convenient.
