Description

Nasogastric tube cannula convenient to insert

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a nasogastric tube cannula convenient to insert.

Background

The jaw face surgery patient needs to insert the stomach tube to assist feeding after the operation, but the radian of nasopharyngeal cavity department is great, and the stomach tube point is discounted at the nasopharyngeal cavity very easily appears when the intubate, and patient singultus can cause esophagus muscle tension in addition, increases the intubate degree of difficulty. For this situation, there are several treatments, firstly, the doctor tries several times until successful, but it is easy to cause hemorrhage due to mucosa and soft tissue injury or mistaken airway entry; secondly, a video laryngoscope is used for assisting in observation, but the maxillofacial operation can cause the structural change of the oral cavity, and the video laryngoscope is not suitable for being used in some cases; thirdly, the gastric tube intubation is abandoned and intravenous nutrition is changed, but the side effect is larger.

Disclosure of Invention

The utility model aims to provide a nasogastric tube cannula convenient to insert, which is used for solving the problems that the nasogastric tube cannula in the prior art is difficult to operate and is easy to cause damage and bleeding of mucous membranes and soft tissues of patients.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: the nasogastric tube intubation convenient to insert comprises a tube body, wherein the front end of the tube body is called a tube head, a plurality of through holes are uniformly formed in the tube head, an O-shaped arc-shaped shrinkage structure is arranged at the end part of the tube head, and a connector for connecting an injector is arranged at the tail end of the tube body; a channel is arranged in the pipe wall, a traction rope is arranged in the channel, one end of the traction rope is fixedly connected in the pipe wall opposite to the channel, and the other end of the traction rope extends to the outside of the joint.

Optionally, the tube body is made of silica gel.

Optionally, a winding rod is arranged on the outer wall of the pipe body at a position close to the joint.

Optionally, the traction rope is a collagen wire.

Optionally, the openings at two ends of the channel are all obliquely arranged.

Optionally, scale marks for marking the length of the pipe body are arranged on the outer wall of the pipe body.

The nasogastric tube cannula convenient to insert has the following advantages:

(1) When the tube head is inserted into the nasopharyngeal cavity, a doctor pulls the traction rope, the tube head of the nasogastric tube can be bent downwards and enter the esophagus of a patient, the tube head cannot be bent at the nasopharyngeal cavity of the patient, the try times of the doctor are reduced, and the damage and uncomfortable feeling of the patient caused by the intubation process are reduced.

(2) The winding rod can play a fixed role on the traction rope outside the joint.

(3) Collagen line can be dissolved by gastric juice, and when nasogastric tube inserted in place, the tube head can submerge in gastric juice, and gastric juice can dissolve the haulage rope, and the outside haulage rope of pulling joint just can directly pull out the haulage rope this moment.

Detailed Description

The utility model will be further described with reference to the accompanying drawings, wherein the end of the nasogastric tube inserted into the stomach is the front end.

As shown in figures 1-2, the nasogastric tube intubation tube convenient to insert comprises a tube body 1, wherein the tube body 1 is made of silica gel, the silica gel is moderate in hardness and has certain softness, and the nasogastric tube intubation tube can slightly change shape under the driving of a traction rope 4 and is not difficult to intubate due to being too soft. The outer wall of the tube body 1 is provided with scale marks for marking the length of the tube body 1, so that the tube head 2 is positioned approximately during intubation. The front end of the tube body 1 is called as a tube head 2, a plurality of through holes 3 are uniformly formed in the tube head 2, an O-shaped arc-shaped shrinkage structure 6 is arranged at the end part of the tube head 2 and used for reducing the damage of the tube head 2 to the nasal cavity, the nasopharyngeal cavity and the esophagus of a patient and reducing the uncomfortable feeling of the patient. The tail end of the tube body 1 is provided with a joint 5 for connecting with a syringe. The pipe wall is internally provided with the channel 7, the openings at the two ends of the channel 7 are respectively arranged at the pipe head 2 and near the joint 5, the openings at the two ends of the channel 7 are obliquely arranged, the traction rope 4 is placed in the channel 7, and the obliquely arranged openings are convenient for pulling out the traction rope 4 and are not easy to cause jamming. One end of the hauling rope 4 is fixedly connected in the pipe wall opposite to the channel 7, and the other end of the hauling rope 4 extends to the outside of the joint 5.

There are two ways to set the traction rope 4: firstly, the position department that is close to joint 5 of body 1 outer wall is provided with winding pole 8, accomplishes and fix the back at the intubate, twines outside haulage rope 4 on winding pole 8, avoids haulage rope 4 to lead to the fact pulling to the nasal intubate that has fixed, causes the secondary damage to the patient. Secondly, the haulage rope 4 selects for use collagen line, and collagen line can be dissolved by gastric juice, and when nasogastric tube inserted in place, the tube head 2 of nasogastric tube can submerge in gastric juice, and gastric juice dissolves haulage rope 4, and pulling haulage rope 4 just can pull out haulage rope 4 from body 1 this moment, has avoided haulage rope 4 to nasogastric tube's influence.

The application process of the utility model is as follows: firstly, estimating the insertion length of an insertion tube, mainly the position of a nasopharyngeal cavity and the position of a stomach, recording corresponding scale marks, then lubricating the tube head 2, then lightly inserting a nasogastric tube through nostrils at an angle parallel to the bottom of a nasal passage, when the tube head 2 reaches the nasopharyngeal cavity, pulling the haulage rope 4 outwards, and under the driving of the haulage rope 4, the tube head 2 can bend downwards, at the moment, pushing the nasogastric tube again, and the tube head 2 can smoothly enter the esophagus and then enter the stomach again. Multiple attempts are not needed at the nasopharyngeal cavity, the hiccup of the patient is not easy to cause the tension of esophagus muscles, the intubation difficulty is reduced, the damage and bleeding of mucous membrane and soft tissues of the patient are not easy to cause, and the damage to the patient and the uncomfortable feeling of the patient are reduced.

The embodiments described above are merely some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
