Description

Novel sputum suction tube for artificial airway

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to novel inhale phlegm pipe for artifical air flue.

Background

Artificial airway establishment is a prerequisite for mechanical ventilation, with the aim of correcting the patient's hypoxic symptoms, improving ventilation function, and clearing airway secretions at the same time. But it also destroys the nonspecific defense barrier of the respiratory tract of the patient, makes the airway secretion viscous, reduces the movement capacity of the respiratory tract cilia, and causes cell reproduction and displacement. Sputum suction is a generally effective means for clearing secretions of respiratory tract and maintaining the airway, but an improper or ineffective sputum suction mode cannot effectively clear the secretions, can cause damage to the mucous membrane of the respiratory tract, and even increases the chance of lung infection.

At present, three different sputum suction modes exist, and all have certain defects:

1. open type sputum suction: when the sputum is sucked, the artificial airway is disconnected from the pipeline of the respirator, and then the artificial airway is connected with the pipeline after the sputum is sucked. But are prone to interruption of ventilator support, affecting patient oxygenation.

2. A closed sputum suction tube: the whole sputum aspiration process is carried out under a closed condition, a breathing machine loop is not cut off, and the use of the breathing machine is not influenced. It is characterized in that the sputum suction system is directly connected between the trachea cannula and the Y-shaped tube of the respirator. The disadvantage is that the sputum in the oral cavity and the upper airway can not be sucked out.

3. Semi-open type sputum suction; sputum suction is carried out through a telescopic extension pipe with a sputum suction hole between a connecting breathing machine loop and the artificial airway. All sputum aspirating modes, oral cavities and airways need two sputum aspirating tubes, and the cost is increased.

Disclosure of Invention

In order to solve the problem, the utility model discloses a novel inhale phlegm pipe for artifical air flue, simple structure, convenient to use can reduce and inhale the phlegm number of times, increases and inhales the phlegm effect, reduces the emergence of VAP simultaneously.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a novel sputum aspirator for artificial air flue, is including inhaling phlegm pipe head and pipeline part, inhale phlegm pipe head and pipeline part rear end intercommunication, pipeline part front end is the air flue admission pipe, is equipped with the oral cavity admission pipe in pipeline part side, oral cavity admission pipe length weak point is in air flue admission pipe length.

As an improvement of the utility model, the head of the sputum suction tube is provided with a negative pressure suction tube.

As an improvement of the utility model, the bottom of the oral cavity inlet pipe and the air passage inlet pipe are sealed, and the side surface is provided with a side hole.

The utility model has the advantages that:

a novel inhale phlegm pipe for artifical air flue, simple structure, convenient to use can reduce and inhale the phlegm number of times, increases and inhales the phlegm effect, reduces the emergence of VAP simultaneously.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

List of reference numerals:

1. the sputum suction tube comprises a sputum suction tube head part 2, a pipeline part 3, an air flue inlet tube 4, an oral cavity inlet tube 5, a negative pressure suction tube 6 and a side hole.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Aiming at the current situation of the sputum suction tube in the current market, the utility model improves the front end of the sputum suction tube into a double head, one long and one short. The specific situation is as shown in the figure, a novel sputum suction tube for artificial airway, including sputum suction tube head 1 and pipeline part 2, sputum

suction tube head

1 and 2 rear end intercommunications of pipeline part, 2 front ends of pipeline part are air flue admission pipe 3, are equipped with oral cavity admission pipe 4 in pipeline part side, 4 length weak points in the air flue admission pipe 3 of oral cavity admission pipe. When the sputum suction device is used, the long tube (the air passage inlet tube 3) enters the air passage through the sputum suction hole, the short tube (the oral cavity inlet tube 4) enters the oral cavity, the head of the sputum suction tube is provided with the negative pressure suction tube 5, the negative pressure is opened, sputum suction is carried out simultaneously, the structure is simple, the use is convenient, the sputum suction times can be reduced, the sputum suction effect is increased, and the occurrence of VAP is reduced simultaneously.

The utility model discloses oral

cavity admission pipe

4 and 3 bottoms of air flue admission pipes are sealed, and the side all is equipped with side opening 6, is convenient for inhale the phlegm.

The technical means disclosed in the present invention is not limited to the technical means disclosed in the above embodiments, but also includes the technical solution formed by combining the above technical features at will.

Claims

1. A novel sputum aspirator for artificial airway which characterized in that: the sputum suction pipe comprises a sputum suction pipe head and a pipeline part, wherein the sputum suction pipe head is communicated with the rear end of the pipeline part, the front end of the pipeline part is an air flue inlet pipe, an oral cavity inlet pipe is arranged on the side surface of the pipeline part, and the length of the oral cavity inlet pipe is shorter than that of the air flue inlet pipe.
