Abstract

The utility model relates to a guiding tube for medical purpose, which is an esophagus catheter or a tracheal catheter which is used for operational anesthesia or the patients in intensive care unit, specifically, a guiding tube for medical purpose which is used as an esophagus catheter or a tracheal catheter, wherein the inner wall is provided with a fistula easy insertion structure which reduces the mutual contact face between the inner wall and the outer wall of a clinical internal fistula. One mode of execution for the fistula easy insertion structure is that the inner wall of the utility model is provided with a plurality of raised lines along the longitudinal orientation, the other mode of execution is that the inner wall of the utility model is provided with frosted face. The outer wall of the utility can be further provided with frosted face or a plurality of raised lines along the longitudinal orientation. At least one side of the utility model can be further provided with an easy-tearing crack along the longitudinal orientation. The utility model can reduce the friction resistance force which is caused by the mutual contact of the outer wall and the inner wall of the clinical internal fistula, which is convenient for the clinical internal fistula crossing the utility model, and reduces the friction resistance force which is caused by the mutual contact of the outer wall of the utility model and the human organs, and is convenient for the utility model to be inserted into the channel of the human organs.

Description

A kind of medical catheter

Technical field:

This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of medical catheter of using as esophageal intubation guide wire or endotracheal tube is used for surgery anesthesia or Intensive Care Therapy patient's esophageal intubation or tracheal intubation.

Background technology:

(1) present, after the general anesthesia or patient realize under the state of disappearance, for patient's indwelling gastric tube or nasal feeding nutritive canal can alleviate the clear-headed misery of intubate down before patient's art.During operation, at first need the esophageal intubation guide wire is inserted patient's esophagus, then, the clinical built-in tubule with stomach tube or nasal feeding nutritive canal and so on inserts the esophageal intubation guide wire again, under the guiding of esophageal intubation guide wire, finally is inserted into the stomach the inside.

Utility model patent 02271782.X discloses a kind of esophageal intubation guide wire, because of it is provided with the structure that the esophageal intubation guide wire is easily drawn back, is difficult to the problem of taking out so solved after finishing guiding function.But because stomach tube or nasal feeding nutritive canal be in the process of inserting the esophageal intubation guide wire, the contact area of its outer wall and esophageal intubation guide wire inwall is excessive, remain at frictional resistance big, the difficult problem of insertion smoothly.

The esophageal intubation guide wire is being inserted in the process of esophagus along patient's nasopharynx part,,, also existing frictional resistance big, the difficult problem of inserting smoothly so contact area is excessive because esophageal intubation guide wire outer wall closely contacts with patient's mucous membrane of nasopharynx.

(2) endotracheal tube is the indispensable medical apparatus and instruments that general anesthesia patient is kept breathing, and endotracheal tube simultaneously, also is used to the sputum that attracts patient's trachea interior except setting up respiration channel.When inhaling expectorant, the also essential air flue that inserts patient through endotracheal tube of used sputum aspirator tube.At present, when equally also existing sputum aspirator tube to insert endotracheal tube, the problem that frictional resistance is bigger.

Summary of the invention:

The purpose of this utility model is exactly to propose a kind of medical catheter that is used for esophageal intubation or tracheal intubation, specifically is the medical catheter of using as esophageal intubation guide wire or endotracheal tube.At first can make clinical built-in tubule more easily insert the medical catheter of using as the esophageal intubation guide wire as stomach tube or nasal feeding nutritive canal and so on, can make clinical built-in tubule more easily insert the medical catheter of using as endotracheal tube, moreover can make above-mentioned medical catheter more easily insert the human organ passage of pharyngeal or esophagus and so on as human nasal as sputum aspirator tube and so on.

For achieving the above object, a kind of medical catheter that this utility model is related, its inwall are provided with and reduce the easy insert structure of tubule that is in contact with one another face with clinical built-in tubule outer wall.

The easy insert structure of above-mentioned tubule in a kind of preferred implementation, is meant that the medical catheter inwall longitudinally is provided with a plurality of raised lines, and the cross section of this raised line can be semicircular.In another kind of preferred implementation, be meant that the medical catheter inwall is provided with frosting.

As improvement, above-mentioned medical catheter outer wall longitudinally also can be provided with a plurality of raised lines, and the cross section of this raised line can be semicircular.Perhaps, above-mentioned medical catheter outer wall also can be provided with frosting.

At least one side of above-mentioned medical catheter can also be provided with easily openable crack longitudinally.

Inwall at medical catheter is provided with the easy insert structure of tubule, the easy insert structure of this tubule reduces the contact area between medical catheter inwall and the clinical built-in tubule outer wall, and then minimizing frictional resistance each other, make clinical built-in tubule can more easily insert and pass through medical catheter.Outer wall at medical catheter is provided with frosting, perhaps, longitudinally be provided with a plurality of raised lines, play the effect that reduces medical catheter outer wall and human organ passage contact area, and then minimizing frictional resistance each other, make medical catheter can more easily insert the human organ passage.

Description of drawings:

Fig. 1 is the structural representation of this utility model embodiment;

Fig. 2 is the cross-sectional structure sketch map of Fig. 1;

The specific embodiment:

The CONSTRUCTED SPECIFICATION of this utility model embodiment is described in detail in detail below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, be this utility model embodiment that uses as the esophageal intubation guide wire, it is semicircular raised lines 3 that the inwall of present embodiment longitudinally is provided with a plurality of cross sections, is present embodiment and reduces the easy insert structure of tubule that is in contact with one another face with clinical built-in tubule outer wall.The present embodiment both sides also are provided with easily

openable crack

1,2 longitudinally.

The easy insert structure of tubule that above-mentioned minimizing and clinical built-in tubule outer wall are in contact with one another face is meant that this utility model medical catheter inwall longitudinally is provided with a plurality of raised lines 3, certainly, can also be other structure, as: can also be meant that this utility model medical catheter inwall is provided with frosting.

This utility model medical catheter outer wall also can be provided with frosting, perhaps, it is semicircular raised lines that this utility model medical catheter outer wall also can longitudinally be provided with a plurality of cross sections, so that reduce the contact area of this utility model medical catheter outer wall and human organ passage.
