Description

Intelligent ventilation catheter with cleaning function

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an intelligent ventilation catheter with a cleaning function.

Background

During surgery, surgeons typically use catheters to assist in ventilating the patient's lungs for breathing. There are generally two types of catheters, depending on their construction and use. The first type is often referred to as endotracheal intubation. Endotracheal intubation generally requires the insertion of a catheter through the upper airway, such as the mouth, nose or trachea. A second type of tube, known as a tracheostomy tube, requires a cut to be made in the neck region at the base of the larynx and to extend into the inner wall of the trachea.

Whether it be an endotracheal tube or a tracheotomy tube, it is common to provide the distal portion of the tube with a balloon that acts as a seal, forming a seal between the tube and the wall of the trachea when inflated or inflated. Thus, during ventilation of the patient, air can only flow through the center of the catheter, thereby eliminating the opportunity for accidental and undesirable escape of air from the lungs. On the other hand, the balloon may also isolate the flow of fluid between the patient's respiratory organs and the stomach and esophagus, preventing the inadvertent flow of stomach acid (low pH, high electrical conductivity) and similar fluids (e.g., saliva, high pH, high electrical conductivity) from the stomach into the esophagus and into the trachea and lungs.

Prior art devices sometimes maintain a seal between the conduit and the wall of the trachea at all times. However, this can lead to the formation of a sustained high pressure on the trachea which can lead to tracheal necrosis. Furthermore, it has been found that when the pressure is sufficiently high, the blood circulation in the tracheal tissue is interrupted, which can cause damage to the tracheal wall. It may be necessary to restore blood circulation by relieving the pressure of the catheter on the trachea by deflation for some time during actual operation, however this may lead to gastric acid from the stomach entering the trachea and lungs via the esophagus, complicating normal breathing of the patient.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, a first embodiment of the present invention provides an intelligent ventilation catheter with a cleaning function, which includes an inflation inlet 10, an inflation tube 20, an air bag 30, and a tube 40; wherein the tube 40 has a first end 41 for connection to a ventilation device and a second end 42 for access into a patient, the balloon 30 being disposed at the tube 40 proximate the second end 42; one end of the inflation tube 20 is communicated with the air bag 30, and the other end is communicated with the inflation port 10; it still includes: the device comprises a connector 50, a main controller 60, a body fluid detection sensor 70, a flushing pipeline 81 and a water pumping pipeline 82; the connector 50 is disposed outside the tube 40 and near the first end 41; the body fluid detection sensor 70 is disposed on the outer side of the tube 40 in an exposed manner, and is close to the air bag 30; the main controller 60 is disposed in the connecting head 50; one end of the flushing pipeline 81 and one end of the water pumping pipeline 82 are fixed in the connector 50, and the other end of the flushing pipeline extends to the upper part of the air bag 30; the body fluid detection sensors are all electrically connected to the master controller 60.

In this embodiment, the intelligent ventilation catheter may be an endotracheal tube or a tracheotomy tube, which has been described in the background section, and the description of the present invention is not repeated herein.

In this embodiment, the ventilation device may be a ventilator or a ventilation balloon, etc. The ventilator may deliver gas (e.g., oxygen or air) through the tube 40 into the respiratory airways of the human body to assist the human body in breathing.

In this embodiment, the balloon 30 functions as a seal, and when a user inflates the inflation tube 20 through the inflation port 10, the balloon 30 expands and forms a seal between the tube body 40 and the tube wall after expansion. Thus, during ventilation of the patient, air can only flow through the center of the tube 40, thereby eliminating the opportunity for accidental and undesirable escape of air from the lungs.

In the present embodiment, the body fluid detecting sensor 70 may be a pH sensor 71 and/or a conductive electrode 72, which is used for detecting whether the body fluid of the human body exists, such as detecting whether gastric acid, saliva, etc. exist.

In this embodiment, the pH sensor 71 may be used to detect gastric acid. Wherein, because the pH value of gastric acid is lower, when the gastric acid flows to the outer side wall of the tube body 40 (generally, the gastric acid is converged above the air bag 30), the pH sensor 71 can detect and generate a pH value, and when the pH value is smaller than a preset first threshold value, which indicates that gastric acid exists, the main controller 60 can issue a prompt to prompt the user to clean the outer wall of the tube body 40.

In this embodiment, the user can clean the outer wall of the pipe body 40 by injecting clean water into the flushing pipe 81 and pumping out water through the pumping pipe 82.

The cleaning mode can be automatic or manual. When performing automatic flushing, the user may effect the filling of the flushing line 81 with fresh water and the withdrawal of water through said flushing line 82 by means of, for example, a needle or similar device.

In the automatic case, the intelligent ventilation catheter further comprises the pump 80, and the pump 80 is connected to one end of the flushing pipe 81 and one end of the pumping pipe 82 respectively and is electrically connected to the main controller 60. The main controller 60 can control the activation of the pump 80, and flush water through the flushing pipe 81 and control the water pumping pipe 82 to pump water until water is drained, so as to clean the outer wall 40 of the pipe body. For convenience of explanation, the following description will be given by taking an example of automatic cleaning, but other cleaning schemes are also within the scope of the present invention.

In this embodiment, the pH sensor 71 can also be used for detecting saliva, wherein, due to the high pH value of saliva, when saliva flows to the outer side wall of the tube 40 (which generally converges above the air bag 30), the pH sensor 71 can detect a pH value, when the pH value is greater than a preset threshold value, indicating that saliva exists, the main controller 60 controls the pump 80 to start, flush water through the flushing pipe 81 and control the water pumping pipe 82 to pump water until water is pumped out, so as to clean the outer wall 40 of the tube.

In the present embodiment, as for the electrically conductive electrode 72, it can be used for detecting a body fluid having electrical conductivity. Since most body fluids of human body have electrical conductivity, when the body fluids flow to the outer side wall of the tube 40 (generally, the body fluids converge above the air bag 30), the conductive electrode 72 can detect and generate a conductivity value, and when the conductivity value is greater than a preset third threshold value, which indicates that body fluids exist, the main controller 60 controls the pump 80 to start, and controls the flushing pipeline 81 to flush water and the water pumping pipeline 82 to pump water until the water is drained, so as to clean the outer wall of the tube 40.

It should be noted that, in the above embodiment, the flushing pipe 81 and the pumping pipe 82 may be integrally disposed outside the pipe body 40, or may first enter the pipe body 40, and then extend back to the outside of the pipe body 40 after penetrating from the inside of the pipe body 40, so as to clean the outer wall of the pipe body 40.

In particular, in view of the fixation of the flushing pipe 81 and the water pumping pipe 82 and in order to prevent the flushing pipe 81 and the water pumping pipe 82 from colliding with the air pipe, the embodiment adopts the design scheme shown in fig. 1.

In summary, the intelligent ventilation catheter with cleaning function provided by the embodiment detects whether body fluid (such as gastric acid or saliva) exists in the catheter body 40 located on the upper side of the air bag 30 through the body fluid detection sensor 70, and automatically cleans the body fluid by controlling the operation of the pump 80 after the body fluid is detected, so that the problem that the body fluid unintentionally flows into the esophagus and enters the trachea and the lung, so that the breathing difficulty of the patient is caused, and the like can be avoided.
