Description

Sputum suction tube for removing sputum-stained biomembrane on inner wall of trachea cannula or tracheotomy catheter

Technical Field

The utility model belongs to the field of breathing consumables, and particularly relates to a sputum suction tube for removing sputum biofilm on the inner wall of a tracheal cannula or a tracheotomy catheter.

Background

When a patient has acute respiratory failure or acute attack of chronic respiratory failure and reaches the degree of invasive ventilation support of a ventilator, an artificial airway is required to be established, and the artificial airway mainly comprises two modes of tracheal intubation and tracheotomy. Patients with respiratory failure typically have or are prone to respiratory infections, increased secretions, decreased airway clearance, and the like. After the artificial airway is established, the original airway profile and protection capability are not complete, a large amount of secretion of a respiratory system needs to be sucked and discharged from the artificial airway, at the moment, some secretion can be adhered and deposited on the inner surface of a tracheal cannula or a tracheotomy catheter to form a biological membrane, so that a large amount of pathogenic microorganisms are promoted to breed and stored on the biological membrane, and the accumulated pathogenic microorganisms easily enter the respiratory system again, so that the infection is delayed repeatedly and is difficult to control, the course of treatment of antibiotics is prolonged, and even the tracheal cannula and mechanical ventilation time is prolonged; meanwhile, the secretion adhered to the inner surface of the trachea cannula or the tracheotomy tube enables the artificial airway to be narrow in different degrees, the ventilation resistance is increased, and the work of breathing is increased. The conventional intravenous and intratracheal antibacterial drug administration mode can only kill pathogenic bacteria in a patient body, but cannot generate effects on secretions and pathogenic microorganisms planted and propagated in biofilms on inner walls of tracheal intubation or tracheotomy catheters, so that the best method is to regularly clear the secretions and the biofilms, but the conventional sputum suction tube and sputum suction mode cannot clear the secretions and the biofilms and cannot kill the pathogenic bacteria in the secretions and the biofilms.

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

Example 1

As shown in fig. 1, an embodiment of the present invention provides a sputum aspirating tube for removing sputum-stained biofilm on an inner wall of a tracheal intubation or a tracheotomy tube, comprising an outer tube 3 and an inner tube 4 which are mutually sleeved, wherein the head of the outer tube 4 is open, the bottom of the outer tube is closed and is provided with a one-way inflation inlet 6, a brushing part comprises an air bag 1 and villi arranged on the surface of the air bag 1 and can be used as a brush, and the air bag 1 is sleeved on the head of the outer tube 3; the two ends of the inner tube 4 are opened, the head part extends out of the air bag 1, and the tail part extends out of the tail part of the outer tube 4, so that an air passage with a through head part and a through tail part is formed, and the smoothness of the artificial air passage can be ensured.

The air bag 1 is made of thick medical PVC material and is in a contraction state before use. When in use, firstly, the gas in the air bag 1 is pumped out to reduce the volume of the air bag 1; the sputum suction tube is placed into a tracheal intubation or a tracheotomy catheter (as shown in figure 2), the fact that the sputum suction tube is pushed to a required distance is confirmed through scales on the outer wall of an inner tube 3, the far end of the inner tube 4 is just positioned in an inner cavity of the far end of the tracheal intubation/tracheotomy catheter, an air bag 1 is inflated through an air injector/air bag pressure gauge 7 at a one-way inflation port 6 to be sufficiently inflated and expanded to a degree that the sputum suction tube can contact the inner wall of the tracheal intubation/tracheotomy catheter and can be sealed in the trachea (as shown in figure 3), and at the moment, fluff 2 is tightly attached to the inner wall of the tracheal intubation/tracheotomy catheter; the sputum suction tube is pulled outwards and slowly, the villus 2 on the air bag 1 can scrub secretion mucosa on the inner wall of the artificial airway in the moving process, meanwhile, the air bag 1 seals the artificial airway, so that a sputum stain biomembrane falling off in the cleaning process can be prevented from entering the deep part of a respiratory tract, the secretion mucosa is pushed out of a tracheal intubation/tracheotomy catheter under the common pushing of the air bag 1 and the villus 2, and the secretion mucosa is collected in an outer bag (an external soft bag, a conventional sputum suction tube has the structure, and is not shown in the figure) when the sputum suction tube is completely pulled out. Then the sputum suction tube and the collected sputum are safely and pollution-free discarded according to the disposable medical supplies.

Example 2

As shown in fig. 4, the embodiment of the present invention provides a second sputum aspirating tube for removing sputum-stained biofilm on the inner wall of an endotracheal intubation or tracheotomy tube based on embodiment 1, which is different from embodiment 1 in that an inner tube 4 is replaced by a solid central post 9, a brushing part is replaced by a brush 8, the brush 8 is arranged at the head of the central post 9 and is received in an outer tube 3, the head and the tail of the outer tube 3 are both open to form an airway which is through from head to tail, so as to ensure that an artificial airway is unobstructed, and the tail of the central post 9 extends out of the outer tube 3.

Before use, the brush 8 is in a contraction state in the outer tube 3; in use, when the distal end of the outer tube reaches the desired position of the distal end of the endotracheal tube/tracheotomy tube (as shown in fig. 5), the central post 9 is pushed to push the brush 8 out of the head of the outer tube 4, so that the brush 8 is unfolded to touch the inner surface of the artificial airway (as shown in fig. 6); the sputum suction tube is pulled out slowly, the brush 8 can brush off and push out the secretion mucosa on the inner wall of the artificial airway gradually in the moving process, and the secretion mucosa is collected in the outer bag when the sputum suction tube is completely pulled out. The brush 8 is contained in the outer tube 3 and is pushed out and unfolded when reaching the required position, so that the mucous membrane of the secretion can be ensured to be brushed and pushed out along one direction, and the fragments of the mucous membrane of the secretion are prevented from falling into the deep part of the artificial airway.

Example 3

As shown in fig. 7, the embodiment of the present invention provides a third sputum aspirating tube for removing the sputum biofilm on the inner wall of the endotracheal tube or tracheotomy tube based on embodiment 2, which is different from embodiment 2 in that a sponge mass 10 is further provided at the head of the central post 9, and the sponge mass 10 and the brush 8 are together housed in the outer tube 3 and in a contracted state (as shown in fig. 8).

As shown in fig. 9, when the artificial airway cleaning device is used, the sponge mass 10 and the brush 8 can be used for cleaning and pushing secretion mucous membranes on the inner wall of the artificial airway together, and meanwhile, the porous structure of the sponge mass 10 has adsorption capacity and can be attached with small mucous membrane fragments which are easy to leak from the bristles of the brush 8, so that the cleaning efficiency and effect are effectively improved.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
