Description

A balloon-expandable endotracheal tube

technical field

The utility model relates to the medical field, in particular to a balloon-expandable tracheal catheter.

Background technique

When the patient suffers from respiratory failure due to airway stenosis, the air bag needs to be intervened. While the tracheal intubation assists ventilation, the existing technology cannot be used at the same time as the air bag expansion. Airbag expansion.

At the same time, because the airway is compressed by the air bag for a long time during the air bag intervention, it may cause the necrosis of the airway mucosa, which brings bad hidden dangers.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art and provide a balloon-expandable tracheal catheter. At the same time as tracheal intubation assists ventilation, the narrowed airway is expanded by the balloon to achieve the purpose of dual treatment, and at the same time, it solves the problem that the airway is compressed by the balloon for a long time. may cause airway mucosal necrosis.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the balloon-expandable tracheal catheter is provided with a tracheal catheter, characterized in that: the upper part of the tracheal catheter is attached with a first airbag and a second airbag, so The side wall of the first air bag is connected with the first air bag inflation end through the first inflation conduit, and the side wall of the second air bag is connected with the second air bag inflation end through the second inflation conduit;

The diameters of the first airbag and the second airbag are both 7.5-10.5 mm, and the lengths are both 4.5-6 cm.

In one embodiment, the front side walls of the first airbag and the second airbag of the tracheal tube are provided with sieve-shaped holes, and the front end of the tracheal tube is closed.

Another embodiment is that the front end of the tracheal tube is open.

The inflatable end of the first airbag and the inflatable end of the second airbag are matched connection ends of a needleless airtight joint without a one-way valve.

The parts not involved in the device are the same as the prior art or can be implemented by using the prior art.

Compared with the prior art, the beneficial effects of the present utility model are as follows: the present utility model can simultaneously use balloon expansion while tracheal intubation assists ventilation, and both are treated at the same time, thereby saving the treatment period. When the patient has respiratory failure due to airway stenosis, the tracheal intubation assists ventilation, and the stenotic airway is expanded by balloon to achieve the purpose of dual treatment. At the same time, the two air bags are alternately inflated or deflated to avoid long-term airway compression and cause airway mucosal necrosis.

The top of the tracheal tube is evenly provided with sieve-shaped holes. When the tracheal tube is inserted into the patient's body, the sieve-shaped holes can help the patient to breathe, disperse the airflow, and at the same time facilitate humidification and negative pressure treatment.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, but not all of the embodiments. , based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work, all belong to the protection scope of the present invention.

Please refer to Figure 1: balloon-expandable endotracheal tube, balloon-expandable endotracheal tube, with endotracheal tube 1, the endotracheal tube uses the existing PU plastic material for endotracheal tubes, and the use of plastic polyurethane meets the environmental protection requirements of ROHS, and has high elasticity. Withstands repeated compression, resists wear, resists dissolution and has low gas permeability.

A first balloon 22 and a second balloon 32 are attached to the upper part of the tracheal tube 1 in close proximity. The first balloon 22 and the second balloon 32 are tightly covered on the outside of the tracheal tube, and the tracheal tube passes through the middle of the balloon. Due to the high elasticity of the material, the air bag expands when it is inflated, and contracts elastically after deflation, which does not affect the ventilation of the airway but does not compress the airway.

The side wall of the first air bag 22 is connected to the first air bag inflation end 21 through the first inflation conduit 2 , and the side wall of the second air bag 32 is connected to the second air bag inflation end 31 through the second inflation conduit 3 .

The diameters of the first airbag 22 and the second airbag 32 are both 7.5-10.5 mm, and the lengths are both 4.5-6 cm.

The first airbag 22 and the second airbag 32 are respectively controlled to be inflated and deflated by an external air pump. The first airbag 22 and the second airbag 32 are inflated and deflated in turn, and can be set to be inflated and deflated intermittently at regular intervals, so that the airway will not be in the same position. produce constant oppression.

In one embodiment, the front side walls of the first airbag 22 and the second airbag 32 of the tracheal tube 1 are provided with sieve-shaped holes 4 , and the front end of the tracheal tube 1 is closed. The sieve holes can disperse the airflow without damaging the airflow continuously passing through the same location.

Another embodiment is that the front end of the tracheal tube 1 is open. The humidified moisture stream can also be vented directly from the front.

The first airbag inflating end 21 and the second airbag inflating end 31 are matching connection ends of a needleless airtight joint without a one-way valve. Due to frequent inflation and deflation, the direction of airflow is alternately changed, and no one-way valve is provided, which is convenient for control. Intermittent control by external equipment through a needle-free hermetic joint can ensure that the airbags alternately press different positions.

When working, insert the tracheal tube into the patient's airway from the trachea, set a balloon at the position of the narrow airway, connect the ventilator at the end of the tracheal tube, and connect to the humidified medical oxygen. At the same time, the first balloon inflation end 21 and the second balloon are inflated. The ends 31 are respectively connected to the inflation and deflation control device through the needleless airtight joint, and the first airbag and the second airbag are controlled intermittently to inflate and deflate alternately, so as to expand the airway and prevent continuous compression of a certain position of the airway.

The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments, and the descriptions in the above-mentioned embodiments and the description only illustrate The principle of the present utility model, without departing from the spirit and scope of the present utility model, the present utility model will also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection is defined by the appended claims and their equivalents.
