Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a monitoring and suction device for the retention on the tracheal catheter balloon. Background Art

[0002] Artificial airway catheters include endotracheal intubation and tracheotomy cannulas. A inflatable balloon is usually provided at the distal end of the catheter. The purpose of setting the balloon in the tracheal catheter is to seal the airway, fix the catheter, ensure the supply of tidal volume, prevent oropharyngeal secretions from entering the lungs, and thus reduce the occurrence of complications such as pulmonary infection.

[0003] The artificial airway is an effective means to ensure airway patency and plays an extremely important role in rescue and respiratory support treatment. However, the establishment of an artificial airway will also damage and disrupt the normal physiological and anatomical functions of the body to a certain extent, causing harm to the patient. After the establishment of the artificial airway, the patient's swallowing is restricted, and oral secretions and gastroesophageal reflux are blocked by the balloon and retained above the balloon, forming retention on the balloon.

[0004] Currently, clinically used suctionable tracheal catheters are used for continuous or intermittent suction of the retention on the balloon to prevent complications such as atelectasis and pulmonary infection. However, the retention on the balloon cannot be effectively removed in a timely manner. Operations such as manually injecting (or extracting) gas to adjust the pressure, manually sucking the drainage tube on the balloon with negative pressure, and injecting normal saline into it for flushing have a large working intensity, poor operation accuracy, overly simple structure, no real-time monitoring, untimely control, low precision, and extensive management.

[0005] Therefore, the present invention proposes a monitoring and suction device for the retention on the tracheal catheter balloon to solve the above problems. Summary of the Invention

The trachea passes through the middle position of the guiding tube, and the balloon is provided at the bottom end of the guiding tube. When the balloon is inflated, there is an indented groove inside it, and a pressure sensor is provided at the bottom of the groove. Below the internal groove of the balloon, a barometric pressure sensor is provided. In the interlayer between the guiding tube and the trachea, there are a drainage tube, an inflation tube, a barometric pressure sensor conduction wire, a physiological saline input tube, and a pressure sensor conduction wire. One end of the drainage tube is connected to the bottom of the balloon groove, and the other end of the drainage tube is connected to a collection bottle. One end of the inflation tube is connected to the balloon, and the other end of the inflation tube is connected to a balloon inflation device. One end of the barometric pressure sensor conduction wire is electrically connected to the barometric pressure sensor, and the other end of the barometric pressure sensor conduction wire is electrically connected to a monitoring controller. One end of the pressure sensor conduction wire is electrically connected to the pressure sensor, and the other end of the pressure sensor conduction wire is electrically connected to the monitoring controller. One end of the physiological saline input tube is connected to the indented groove inside the balloon, and the other end of the physiological saline input tube is connected to a physiological saline output device.

Detailed implementation mode

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Example 1, referring to Figures 1-4 As shown, a device for monitoring and aspirating residues on a tracheal catheter airbag includes a guiding tube 1, a trachea tube 2 and an airbag 3. The trachea tube 2 runs through the middle position of the guiding tube 1, and the airbag 3 is arranged at the bottom end of the guiding tube 1. There is a groove sunken inside the airbag 3 in the inflated state, and a pressure sensor 18 is arranged at the bottom of the groove. An air pressure sensor 17 is arranged below the internal groove of the airbag 3. A drainage tube 4, an inflation tube 10, an air pressure sensor conduction wire 11, a physiological saline input tube 14 and a pressure sensor conduction wire 16 are arranged in the interlayer between the guiding tube 1 and the trachea tube 2. One end of the drainage tube 4 is connected to the bottom of the groove of the airbag 3, and the other end of the drainage tube 4 is connected to a collection bottle 5. One end of the inflation tube 10 is connected to the airbag 3, and the other end of the inflation tube 10 is connected to an airbag inflation device 9. One end of the air pressure sensor conduction wire 11 is electrically connected to the air pressure sensor 17, and the other end of the air pressure sensor conduction wire 11 is electrically connected to the monitoring controller 12. One end of the pressure sensor conduction wire 16 is electrically connected to the pressure sensor 18, and the other end of the pressure sensor conduction wire 16 is electrically connected to the monitoring controller 12. One end of the physiological saline input tube 14 is connected to the sunken groove inside the airbag 3, and the other end of the physiological saline input tube 14 is connected to a physiological saline output device 13.

[0017] Example 2, the collection bottle 5 is connected to a negative pressure device 7 through a negative pressure connecting tube 6, and a negative pressure gauge 9 is arranged on the negative pressure connecting tube 6.

[0018] Example 3, a water pressure gauge 15 is arranged on the physiological saline input tube 14.

[0019] Example 4, the monitoring controller 12 is composed of a base, a printed electronic circuit board, an LED display screen and a battery.

[0020] In Example 5, a measuring range is provided on the surface of the collection bottle 5.

[0021] Working principle: During actual operation, medical staff insert part of the guiding tube 1 into the patient's body, and then start the airbag inflation device 9. The airbag inflation device 9 injects air into the airbag 3 through the trachea 2 to seal the airway and fix the guiding tube 1. During the inflation of the airbag 3, the air pressure sensor 17 can monitor the inflation status of the airbag 3 in real time and display it through the monitoring controller 12, so as to judge whether the airbag 3 is fully inflated. There is a groove in the sunken airbag 3 in the fully inflated state. The patient's oral secretions and gastroesophageal reflux are blocked by the airbag and stay inside the groove. The pressure sensor 18 provided at the bottom of the groove can monitor the retained substances and display them through the monitoring controller 12. When retained substances are generated, the negative pressure device 7 generates negative pressure suction, and the retained substances can flow into the collection bottle through the drainage tube 4. In addition, normal saline can be injected into the sunken groove of the airbag 3 through the normal saline output device 13 and the normal saline input tube 14 for flushing, and the flushing normal saline can flow into the collection bottle through the action of the negative pressure device 7 via the drainage tube 4.
