Description

A nasotracheal tube that clears sputum accumulation

technical field

The invention relates to the field of medical devices, in particular to a nasotracheal intubation capable of removing sputum accumulation.

Background technique

Endotracheal intubation technology is widely used in emergency departments, various ICUs, anesthesiology departments, various wards and various emergency scenes outside the hospital. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration.

Under normal circumstances, due to the natural response of the oral cavity to the insertion of foreign bodies, a large amount of saliva, phlegm and other secretions will be produced. Various liquids are mixed together and flow to the balloon position under the action of gravity, where phlegm is formed. These secretions It is also easy to adhere to the inner and outer walls of the endotracheal intubation, which not only causes sensory discomfort of the patient and affects the ventilation effect of the endotracheal intubation, but also provides a space for the colonization and growth of bacteria, which is easy to cause infection. Therefore, in the nursing process of tracheal intubation, it is necessary to regularly suck out the sputum from the inner and outer walls of the tracheal intubation, but some of these secretions are relatively viscous, so it is difficult to completely suck out, and if it accidentally flows into the lungs, it is easy to Serious diseases such as pneumonia. During tracheal intubation, it is also clinically found that the contact site between the trachea and the balloon often produces an inflammatory response due to prolonged stimulation, increasing the pain of the patient.

Existing publication number CN106924854A is a kind of tracheal intubation capable of removing sputum accumulation and reducing inflammatory response, the tracheal intubation is provided with a tube body, a ventilator joint, a vent, an air bag, an inflation channel and an inflation tube, so the The inner wall and outer wall of the tube body and the outer wall of the air bag are provided with hydrophobic and oleophobic layers; the air bag is provided with several convex rings, and the proximal edge of the most proximal convex ring protrudes in the proximal direction so as to make the balloon and the tube A ring-shaped accommodating groove is formed between the bodies; the edge of the ventilation port is curled in the pipe body toward the proximal direction to form a receiving groove; the inner wall of the pipe body is provided with a suction channel, and the suction channel is provided with The first suction hole and the second suction hole, the distal opening of the suction channel is the third suction hole; the first suction hole opens outward and is located at the proximal end of the third suction hole, the The second suction hole communicates with the receiving groove, the third suction hole communicates with the receiving groove; the proximal end of the suction channel is connected with a suction pipe. After the balloon is pumped after use, the remaining sputum in the accommodating groove formed between the balloon and the tube will flow to the throat or even the lungs along the pumped balloon, which is a potential safety hazard. A tracheal intubation tube with better cleaning effect can solve the above problems.

SUMMARY OF THE INVENTION

The invention provides a nasotracheal intubation capable of removing sputum accumulation, and solves the problem of poor sputum cleaning effect of the existing tracheal intubation by technically transforming the existing tracheal intubation.

In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: a nasotracheal intubation capable of removing accumulation of sputum, comprising: a tube body, a ventilator connector, an airbag inflation assembly, a sputum suction tube, a vent and an airbag, An inflation channel is arranged on the inner wall of the tube, one end of the inflation channel is communicated with the airbag through the inflation hole, and the other end is connected with the airbag inflation assembly connected to the tube body, and the airbag is arranged around the outer wall of the tube, An annular liquid accumulation groove is formed in the upper direction of the connection between the tube body and the airbag;

The inner wall of the pipe is also provided with a sputum suction pipe, which divides the sputum suction pipe into a liquid suction pipe and a medicine injection pipe through the partition wall provided in the middle, and the suction pipe and the sputum suction hole opened at the bottom of the effusion tank. The outer wall of the tube above the effusion tank is provided with a drug injection hole, the drug injection tube is communicated with the drug injection hole, and the other end of the sputum suction tube facing away from the tube body is connected to the suction tube disposed outside the tube body. Connect the sputum connector.

Further, the sputum suction joint is provided with a semicircular fan blade, and the fan blade is installed at the center of the partition wall by a pin so that the fan blade can rotate relative to the suction tube and completely cover the suction tube or the medicine injection tube.

Compared with the prior art, the present invention has the following beneficial effects:

1) In the present invention, a ring-shaped effusion groove is formed by recessing the tube body inward, and a suction hole is opened at the bottom of the effusion groove. The effusion groove can accommodate the secretions that slip off the outer wall of the tube, and a syringe is used at the suction joint. When pumping, a negative pressure is formed in the suction tube, and the secretion is sucked from the suction hole set at the bottom of the effusion tank into the suction tube, and finally pulled out into the syringe. The suction is more thorough and easy to use. The airbag needs to be pumped during intubation. At this time, the remaining sputum still accumulates in the effusion tank and is taken out of the trachea with the tracheal intubation. It will not splash into the trachea and cause infection.

2) The present invention increases the space utilization efficiency by arranging the suction tube at the inner wall of the tube, and separates it into a suction tube and a drug injection tube, and at the same time, the communication channel can be switched by rotating the suction joint, and the sterilization is carried out by a syringe. The drug is injected into the larynx for sterilization and disinfection, which avoids the inflammatory reaction at the contact site between the trachea and the balloon due to prolonged stimulation, and then switches to the pipette to extract the residual liquid medicine to complete the sterilization and cleaning of the trachea.
