Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a tracheal intubation device with an adjustable air bag for measuring and controlling pressure. Background Art

[0002] Endotracheal intubation cuff management is an important part of artificial airway management. Its purpose is to close the airway, fix the catheter, ensure the supply of tidal volume, and prevent oropharyngeal secretions from entering the lungs, thereby reducing lung infection and airway-related complications.

[0003] The pressure of the endotracheal tube cuff should be continuously controlled to reach the minimum closure capacity of the cuff to reduce the damage of the cuff to the tracheal wall and avoid aspiration and affect the tidal volume. At present, nurses in clinical practice manually measure the cuff pressure every 6-8 hours. The cuff pressure needs to be adjusted and measured at the right time points such as sputum suction, oral care, subglottic suction, position change, high airway pressure, low airway pressure or weak spontaneous breathing of the patient. The cuff pressure measurement and pressure control operation is frequent. The minimum closure capacity technology of the cuff requires two people to operate and cooperate at the same time. The quality is unstable and time-consuming. At the same time, the cuffs of existing endotracheal tubes are mostly fixed on the endotracheal tube. When the endotracheal tube is positioned during operation, the cuff is positioned, and the position of the endotracheal tube remains unchanged, and the working position of the cuff remains unchanged. Therefore, when the cuff is inflated, only local pressure is applied to the same part of the tracheal inner wall. This is easy to cause discomfort to the patient for a long time. Different patients have different conditions and cannot adjust the fixed position of the cuff on the endotracheal tube according to needs. Summary of the invention

[0004] The purpose of the present invention is to provide an endotracheal intubation device with an adjustable airbag pressure measurement and control, so as to solve the problem that the existing endotracheal intubation airbag pressure control requires multiple people to frequently and repeatedly operate, which is time-consuming and labor-intensive, and cannot ensure the continuous stability of the endotracheal intubation airbag pressure. At the same time, the airbag working position cannot be adjusted according to the patient's needs without moving the endotracheal intubation.

[0026] like Figure 1-5 The endotracheal intubation device shown in the figure has an adjustable airbag pressure measurement and pressure control, comprising an endotracheal intubation tube 1, an airbag mounting sleeve 2 is arranged outside the endotracheal intubation tube 1, an auxiliary annular airbag 3 is arranged on the inner wall of the airbag mounting sleeve 2 and is connected to the outer wall of the endotracheal intubation tube 1, the auxiliary annular airbag 3 is connected to the first air supply pipe 4, the first air supply pipe 4 is connected to the control console 6 through the first connector 5, an air supply assembly is arranged in the control console 6 and is connected to the first connector 5, a main airbag 7 is arranged on the airbag mounting sleeve 2, the main airbag 7 is connected to the second air supply pipe 8, the second air supply pipe 8 is connected to the air supply control assembly through the second connector 9, the air supply control assembly is arranged in the control console 6, a subglottic suction port 10 is arranged near one end of the first air supply pipe 4 of the main airbag 7, the subglottic suction port 10 is connected to the suction tube 11, and the suction tube 11 is connected to the control console 6 through the negative pressure aspirator 12. It should be noted that one end of the negative pressure suction device 12 is connected to a storage tank for storing sputum produced by subglottic suction for subsequent processing. The subglottic suction port 10 can be set to multiple, evenly and equidistantly arranged in the airbag mounting sleeve 2, and all connected to the first air supply pipe 4 through a branch pipe. The working state of the negative pressure suction device 12 is set to intermittent suction, suction once every 4 hours, and the frequency can be increased or decreased as appropriate. The negative pressure value is: -100 to -150 mmHg.

[0027] Specifically, the first air pipe 4, the second air pipe 8 and the suction pipe 11 are all embedded in the inner wall of the airbag mounting sleeve 2. It should be noted that the embedded arrangement of the first air pipe 4, the second air pipe 8 and the suction pipe 11 will reduce their occupied space and facilitate the normal use of the tracheal tube 1.

[0028] Specifically, the first connector 5 and the second connector 9 are both quick connectors, and the suction tube 11 is connected to the negative pressure suction device 12 via the quick connector. It should be noted that the provision of the quick connector will enable the first gas supply pipe 4, the second gas supply pipe 8 and the suction tube 11 to be quickly installed and disassembled while ensuring their sealing and stability.

[0029] Specifically, the control panel, switch button 13, display screen 14, pressure gauge 15, battery, charging port are arranged on the console 6, and a vent is arranged on the side of the console 6. It should be noted that the console 6 is also provided with an alarm or an alarm light. When the pressure value exceeds the prescribed range, the alarm or the alarm light will sound an alarm to remind the medical staff to deal with it in time. The working principle of the above structure is an existing mature technology and will not be described in detail here.

[0030] Specifically, the air supply assembly includes a first micro air pump, which is arranged in the console 6, a connecting pipe is arranged at one end of the first micro air pump, and the other end of the connecting pipe is connected to the first connector 5, a pressure sensor is arranged on the connecting pipe, and the pressure sensor, the first micro air pump, the control board, and the display screen 14 are electrically connected. It should be noted that the first micro air pump adopts the DO9 series micro air pump sold by Chengdu Hailin Technology Co., Ltd. The first micro air pump works with the pressure sensor, the connecting pipe, and the first connector 5 to inflate and deflate the auxiliary annular airbag 3, thereby achieving the effect that the airbag installation sleeve 2 uses the auxiliary annular airbag 3 to expand and fix, and deflates to loosen the tracheal tube 1.

[0031] Specifically, the gas delivery control component includes a second micro air pump, which is arranged in the console 6. An auxiliary connecting pipe is arranged at the delivery end of the second micro air pump. A pressure gauge 15 and a flow sensor, a solenoid valve, and a pressure controller are arranged on the auxiliary connecting pipe. The auxiliary connecting pipe is connected to the second connector 9. The second micro air pump, the flow sensor, and the solenoid valve are electrically connected to the control panel and the display screen 14 respectively. It should be noted that the second micro air pump adopts the DO9 series micro air pump sold by Chengdu Hailin Technology Co., Ltd. The second micro air pump works with the pressure gauge 15 and the flow sensor, solenoid valve, and pressure controller to inflate and deflate the main air bag 7. At the same time, the air bag pressure is set to a pressure value of 25-30cmH2O during the process; the flow sensor is started to automatically detect the air leakage in the patient's trachea, and the air bag pressure is increased at a rate of 0.1ml gas each time until there is no gas leakage when the patient inhales, and the minimum closure capacity of the air bag is reached; for patients with respiratory infectious diseases known or suspected to be transmitted by droplets or aerosols, if high airway pressure is encountered, the air bag pressure can be accurately adjusted to the tracheal tube air pressure 5cmH20 higher than the peak airway pressure. When the patient's airway pressure is low or the spontaneous breathing is weak and sputum is suctioned, the air bag pressure can be appropriately increased. For patients with tracheotomy who do not need mechanical ventilation, if the autonomous airway protection ability is good, the air bag can be completely deflated.

[0032] Specifically, the airbag installation sleeve 2 and the tracheal tube 1 are both made of transparent PVC hose material, a spiral steel wire is attached to the wall of the tracheal tube 1, a scale line is set on the outer wall of the tracheal tube 1, and a blue marking line that is not transparent to X-rays is set on the outer wall of the airbag installation sleeve 2. It should be noted that the setting of the spiral steel wire attached to the wall of the tracheal tube 1 will make the tube body softer and prevent it from being folded. At the same time, the setting of the scale line will facilitate the observation of the depth of the tracheal tube 1 inserted into the trachea. The blue marking line that is not transparent to X-rays is set on the airbag installation sleeve 2, which can accurately locate the position where the airbag installation sleeve 2 is placed.

[0033] Specifically, the airbag installation sleeve 2 and the endotracheal tube 1 are detachably arranged, and the length and diameter thereof can be changed according to the requirements. It should be noted that the airbag installation sleeve 2 can be installed on the endotracheal tube 1 in advance according to the patient's requirements, and the working position of the main airbag 7 on the endotracheal tube 1 can be adjusted to fix the endotracheal tube 1 for patients in different conditions.

[0034] The working principle of this specific embodiment is as follows: first, the airbag installation sleeve 2 is installed outside the endotracheal tube 1 according to the patient's needs, and the main airbag 7 is adjusted to the required working position. Then, the auxiliary annular airbag 3 is inflated by the first micro air pump in cooperation with the pressure sensor, the connecting tube, and the first connector 5, so that the airbag installation sleeve 2 is assembled and fixed to the endotracheal tube 1;

[0035] Then the tracheal cannula 1 is intubated. When the tracheal cannula 1 reaches the desired working position, the tracheal cannula 1 is fixed. Then, the second micro air pump cooperates with the pressure gauge 15, the flow sensor, the solenoid valve, and the pressure controller to inflate the main airbag 7, so that the tracheal cannula 1 is fixed in the patient's trachea. During this process, the display screen 14 will display the pressure of the main airbag 7 in real time to ensure that it is at a continuous and stable pressure value.

[0036] When subglottic suction is required, the negative pressure suction device 12 is used to cooperate with the suction tube 11 and the subglottic suction port 10 to perform suction;

[0037] When it is necessary to adjust the fixed position of the main airbag 7, there is no need to remove the endotracheal tube 1 in the patient's trachea. Just deflate the main airbag 7 and the auxiliary annular airbag 3, and then adjust the working position of the airbag mounting sleeve 2 through the suction tube 11, the second air supply pipe 8, and the first air supply pipe 4. After the airbag mounting sleeve 2 is adjusted into place, the main airbag 7 and the auxiliary annular airbag 3 can be inflated and fixed.

[0038] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
