Description

An easy-to-insert nasogastric tube

technical field

The utility model relates to the technical field of medical equipment, in particular to a nasogastric tube intubation tube which is convenient for insertion.

Background technique

Maxillofacial surgery patients need gastric tube to assist feeding after surgery, but the curvature of the nasopharyngeal cavity is large, and the tip of the gastric tube is likely to be discounted in the nasopharyngeal cavity during intubation, and the patient's hiccups will cause esophageal muscle tension , increasing the difficulty of intubation. In response to this situation, there are several ways to deal with it. One is that the doctor tries many times until it succeeds, but it is easy to cause mucosal and soft tissue damage, bleeding or stray into the airway; the other is to use video laryngoscope to assist observation, but maxillofacial surgery will In some cases, it is not suitable to use video laryngoscope because of the change of oral structure; the third is to abandon gastric tube intubation and use parenteral nutrition, but the side effects are relatively large.

Utility model content

The purpose of the utility model is to provide an easy-to-insert nasogastric tube intubation, which is used to solve the problem in the prior art that the nasogastric tube intubation is difficult to operate and easily causes bleeding of the patient's mucous membrane and soft tissue.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a nasogastric tube intubation tube for easy insertion, including a tube body, the front end of the tube body is called a tube head, and several through holes are evenly arranged on the tube head, and the tube head The end of the tube is provided with an O-shaped arc-shaped contraction structure, and the end of the tube body is provided with a joint for connecting the syringe; a channel is provided in the tube wall, and a traction rope is placed in the channel, and one end of the traction rope is fixedly connected to the tube opposite the channel. Inside the wall, the other end of the pull rope extends outside the joint.

Optionally, the tube body is made of silica gel.

Optionally, a winding rod is provided at a position close to the joint on the outer wall of the tube.

Optionally, the traction rope is made of collagen thread.

Optionally, the openings at both ends of the channel are inclined.

Optionally, the outer wall of the pipe body is provided with a scale mark indicating the length of the pipe body.

The easy-to-insert nasogastric tube intubation of the utility model has the following advantages:

(1) When the tube head is inserted into the nasopharyngeal cavity, the doctor pulls the traction rope, and the tube head of the nasogastric tube will bend downward and enter the patient's esophagus instead of coiling in the patient's nasopharyngeal cavity, reducing The number of attempts by the doctor can reduce the damage and discomfort caused by the intubation process to the patient.

(2) The winding rod can fix the traction rope outside the joint.

(3) The collagen thread can be dissolved by gastric juice. When the nasogastric tube is inserted in place, the tube head will be submerged in the gastric juice, and the gastric juice can dissolve the traction rope. At this time, pulling the traction rope outside the connector can directly pull the traction rope out .

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further, and the end that nasogastric tube is inserted in the stomach is the front end.

As shown in Figure 1-Figure 2, a nasogastric tube intubation that is easy to insert includes a tube body 1, the material of the tube body 1 is silica gel, the hardness of the silica gel is moderate and has a certain degree of softness, and it can It changes shape slightly and is not too soft to intubate. The outer wall of the tube body 1 is provided with a scale mark indicating the length of the tube body 1, which is convenient for roughly positioning the position of the tube head 2 during intubation. The front end of the tube body 1 is called the tube head 2, and several through holes 3 are evenly arranged on the tube head 2, and the end of the tube head 2 is provided with an O-shaped arc-shaped contraction structure 6, which is used to reduce the impact of the tube head 2 on the patient's nasal cavity, The damage of nasopharyngeal cavity and esophagus reduces the discomfort of patients. The tail end of the tube body 1 is provided with a joint 5 for connecting a syringe. A channel 7 is arranged in the pipe wall, and the openings at both ends of the channel 7 are respectively arranged at the pipe head 2 and near the joint 5. The openings at both ends of the channel 7 are inclined, and a traction rope 4 is placed in the channel 7. The pulling out of the traction rope 4 is not prone to jamming. One end of the traction rope 4 is fixedly connected in the pipe wall opposite to the channel 7 , and the other end of the traction rope 4 extends to the outside of the joint 5 .

There are two ways of setting the traction rope 4: one is that the outer wall of the pipe body 1 is provided with a winding rod 8 near the joint 5, and after the intubation is completed and fixed, the external traction rope 4 is wound on the winding rod 8 , to avoid pulling the traction rope 4 to the fixed nasal cannula, causing secondary damage to the patient. The second is that the traction rope 4 is made of collagen thread, and the collagen thread can be dissolved by gastric juice. When the nasogastric tube is inserted in place, the tube head 2 of the nasogastric tube will be immersed in the gastric juice, and the gastric juice will dissolve the traction rope 4. At this time, pull the traction The rope 4 can pull the traction rope 4 out of the tube body 1, avoiding the influence of the traction rope 4 on the nasogastric tube.

The use process of the utility model is as follows: first estimate the insertion length of the intubation tube, mainly the position of the nasopharyngeal cavity and the position of the stomach, and record the corresponding scale line, then lubricate the tube head 2, and then use it to connect with the nasal passage Gently insert the nasogastric tube through the nostril at a parallel angle at the bottom. When the tube head 2 reaches the nasopharyngeal cavity, pull the traction rope 4 outward. Driven by the traction rope 4, the tube head 2 will bend downward. At this time Then push the nasogastric tube, the tube head 2 will smoothly enter the esophagus, and then enter the stomach. There is no need to make multiple attempts at the nasopharyngeal cavity, and it is not easy to cause the patient's hiccups to cause esophageal muscle tension. The difficulty of intubation is reduced, and it is not easy to cause the patient's mucous membrane and soft tissue damage and bleeding, reducing the damage to the patient and the patient's discomfort.

The embodiments described above are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
