Description

Technical Field

[0001] This utility model relates to pressure monitoring devices, and more particularly to a mini endotracheal intubation cuff pressure monitoring device. Background Technology

[0002] Establishing an artificial airway is a frequent part of mechanical ventilation, and the endotracheal tube is the core medical device for this purpose. The endotracheal tube typically has a cuff for airway sealing, and the pressure of this cuff needs to be set within a specific range, generally 25-30 cmH2O water column. Traditionally, inflation was performed at set intervals using a syringe or manual gauge, which lacked precise pressure monitoring. Both excessively high and low cuff pressure can lead to patient safety issues. Therefore, dynamic management of the cuff pressure is necessary.

[0003] Currently, the balloon pressure management devices used in the medical field are large terminal devices. Their bulky size makes them impractical for portable use, requiring fixed installation on medical devices such as IV stands and pendants, thus limiting their flexibility and application scenarios. Furthermore, these devices require external power supply, making them extremely inconvenient to use. In addition, these devices typically need to be connected to the patient via monitoring and inflation tubing, which further burdens the already complex tubing systems of critically ill patients.

[0063] The mini endotracheal intubation airbag pressure monitoring device of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0064] Reference Figures 1 to 4 As shown, the mini endotracheal intubation cuff pressure monitoring device provided according to the embodiment of this utility model includes an endotracheal tube 10, a cuff 20, a pressure monitor 30, and an inflation device 40.

[0065] Specifically, both the endotracheal tube 10 and the cuff 20 utilize existing endotracheal tube 10 components. The cuff 20 is positioned on the endotracheal tube 10 and adjacent to its proximal end, enabling it to form an effective seal with the inner wall of the patient's trachea after inflation. An inflation tube 201 is connected to the cuff 20, which has a quick-connect male connector 201a. Inflation can be performed through this tube 201 to inflate the cuff 20, causing it to expand and seal the patient's trachea.

[0066] The pressure monitor 30 includes a gauge 301, which accurately monitors the pressure inside the airbag 20 and converts it into a numerical value for display. One side of the gauge 301 has an inlet pipe 3011, and the other side has an outlet pipe 3012. The end of the inlet pipe 3011 has an inflation connector, which is equipped with a switch 3013 that controls the opening and closing of the inlet pipe 3011. This switch 3013 can be a rotary valve or a push-button switch, allowing the operator to control the inlet pipe 3011 with one hand. The end of the outlet pipe 3012 has a quick-connect female connector 3014 that plugs into the quick-connect male connector 201a. Through the cooperation of the quick-connect female connector 3014 and the quick-connect male connector 201a, the gauge 301 can be quickly connected to the inflation pipe 201 of the airbag 20 in clinical use.

[0067] The inflation device 40 is connected to the inflation connector via a connecting pipe to inflate the airbag 20 after passing through the pressure monitor 30. The inflation device 40 can be a manual airbag squeezer or a portable electric air pump. When the inflation device 40 is working, it inflates the airbag 20. The gas flows through the monitoring gauge 301. After inflation, the switch 3013 can be turned off. At this time, the gas pressure remains stable, and the pressure value can be monitored and displayed by the monitoring gauge 301.

[0068] The monitoring device is equipped with a display screen 3016, which has a monitoring value display area, an upper limit value display area, and a lower limit value display area. The monitoring value display area displays the actual pressure value inside the airbag 20 in real time; the upper limit value display area displays the preset safe upper limit value of the airbag 20 pressure, and the lower limit value display area displays the preset safe lower limit value of the airbag 20 pressure, which facilitates medical staff to quickly judge the pressure status of the airbag 20.

[0069] Understandably, the monitoring meter 301 is powered by a rechargeable lithium battery, which solves the problem of traditional equipment requiring an external power source.

[0070] In use, medical staff first insert the endotracheal tube 10 into the patient's airway, then connect the quick-connect female connector 3014 of the pressure monitor 30 to the quick-connect male connector 201a on the cuff 20 of the endotracheal tube 10, and inflate the cuff 20 using the inflation device 40. During inflation, the pressure monitor 30 displays the pressure value inside the cuff 20 in real time, and medical staff can precisely adjust it to the required pressure range based on the displayed value. After inflation is complete, the switch 3013 on the inflation connector is turned off, and the air pressure remains stable. This device can continuously monitor the pressure of the cuff 20.

[0071] The mini endotracheal intubation cuff pressure monitoring device provided in this embodiment of the present invention adopts a miniature pressure monitor 30, and connects to the inflation tube 201 of the cuff 20 by connecting the male quick-connect male connector 201a and the female connector. The pressure monitor 30 is equipped with a display screen 3016 with monitoring value and upper and lower limit display areas to monitor the pressure of the cuff 20 in real time. This not only greatly reduces the size of the device, making it easy to carry and eliminating the need to fix it on an infusion stand or pendant, but also simplifies the connection pipeline with the patient, reduces the complexity of pipeline management, reduces the workload of medical staff, and improves the patient's comfort and freedom of movement. It is particularly suitable for the pressure management needs of the cuff 20 in the intensive care environment.

[0072] In one embodiment of this utility model, the monitoring meter 301 includes a pressure sensor, a processing module, and a warning light. The pressure sensor is used to detect the pressure value in the air outlet pipe 3012, and the warning light includes a green light, a yellow light, and a red light.

[0073] The processing module is connected to the air pressure sensor and the warning light to compare the air pressure value with a preset threshold range. When the air pressure value is within the preset threshold range, the green light is displayed; when the air pressure value is higher than the upper limit of the preset threshold range, the yellow light is displayed; and when the air pressure value is lower than the lower limit of the preset threshold range, the red light is displayed.

[0074] In actual operation, when the processing module detects that the air pressure value is within the preset threshold range, the green light remains on, indicating that the pressure of the cuff 20 is within a safe range and no adjustment is needed. For example, if the preset threshold range is 25-35 cmH2O, when the detected air pressure value is 28 cmH2O, the green light illuminates, and the display screen 3016 simultaneously displays the current pressure value "28 cmH2O", the upper limit of 35, and the lower limit of 25, clearly and intuitively informing medical staff of the current pressure status. When the processing module detects that the air pressure value is higher than the upper limit of the preset threshold range, the yellow light illuminates and flashes at a slower frequency, while the green light turns off, reminding medical staff that the pressure of the cuff 20 is too high. Medical staff need to reduce the pressure of the cuff 20 to avoid ischemic damage to the patient's tracheal mucosa caused by prolonged high pressure. When the processing module detects that the air pressure value is lower than the lower limit of the preset threshold range, the red light illuminates and flashes rapidly at a faster frequency, reminding medical staff that the pressure of the cuff 20 is insufficient, and there is a possibility that the airway may not be effectively sealed, requiring immediate increase of the cuff 20 pressure.

[0075] This embodiment achieves visualized airbag 20 pressure monitoring and early warning through the combination of a pressure sensor, processing module, and three-color warning lights, enabling medical staff to intuitively judge the airbag 20 pressure status. Different frequencies of light flashing distinguish different levels of pressure abnormalities, providing a highly noticeable reminder effect, greatly improving the safety and convenience of patient airway management, and reducing the workload of medical staff.

[0076] In one embodiment of this utility model, the monitoring table 301 further includes a buzzer, which is connected to the processing module. The processing module is also used to control the buzzer to sound a low-frequency alarm when the air pressure value is higher than the upper limit of the preset threshold range, and to control the buzzer to sound a high-frequency alarm when the air pressure value is lower than the lower limit of the preset threshold range.

[0077] In other words, after receiving the pressure value from the pressure sensor, the processing module first compares the pressure value with a preset safety threshold range. When the detected pressure value is higher than the upper limit of the preset threshold range, the processing module outputs a low-frequency alarm signal to the buzzer, causing it to produce a low-frequency warning sound different from the normal state, to alert medical staff to the potential safety hazard of overpressure. Conversely, when the detected pressure value is lower than the lower limit of the preset threshold range, the processing module outputs a high-frequency alarm signal to the buzzer, causing it to emit a high-frequency warning sound, indicating that the pressure inside the airbag 20 is below the safe range, which may affect the sealing of the airbag 20.

[0078] Employing a dual alarm mode of low-frequency and high-frequency alarms, different abnormal pressure states can be fed back to medical operators more intuitively and easily. This design enables medical staff to identify the nature of the abnormal pressure in a short time and take appropriate measures to adjust the pressure. This significantly improves the safety and ease of operation in medical procedures, ensuring that the airbag 20 pressure monitoring system can work stably and reliably in various environments, effectively reducing the risks caused by abnormal airbag 20 pressure.

[0079] In one embodiment of this utility model, a bypass interface 3018 is provided on the air outlet pipe 3012, and a pressure relief valve 3015 is threadedly connected to the bypass interface 3018 to actively release air pressure when the air pressure value exceeds a predetermined value. This pressure relief valve 3015 is a mechanical pressure relief valve 3015, which automatically opens to release air pressure when the air pressure value exceeds the set value of the pressure relief valve 3015. In practical applications, the set value of the pressure relief valve 3015 can be adjusted by rotating the adjusting knob on the pressure relief valve 3015 according to clinical needs.

[0080] In this embodiment, by setting a bypass interface 3018 on the air outlet pipe 3012 and threading a pressure relief valve 3015 onto it, the function of actively releasing air pressure when the pressure inside the airbag 20 exceeds a predetermined value is realized, ensuring that the internal pressure of the airbag 20 is always kept within a safe range, preventing potential harm to the patient caused by overpressure, and improving the operational stability, ease of operation and safety of the device.

[0081] In some embodiments of the present invention, the pressure monitor 30 further includes a housing 3017 and a clamping assembly 302, wherein the clamping assembly 302 is detachably disposed on the rear side of the housing 3017 for clamping and fixing to the hospital bed.

[0082] The clamping assembly 302 is fixed to the hospital bed or other fixed object using mechanical snap-fit, bolt locking, or elastic gripper structures. During use, medical staff can easily and quickly clamp the pressure monitor 30 onto the hospital bed or other fixed position, ensuring a stable and reliable fixed state of the device during monitoring, and facilitating real-time observation and operation of the pressure monitor 30. Furthermore, the clamping assembly 302 is detachable from the housing 3017, allowing for flexible and convenient use by selecting whether or not to use the clamping assembly 302 as needed.

[0083] In one embodiment of this utility model, the clamping assembly 302 includes a U-shaped seat 3021 and a locking bolt 3022. The bottom wall of the U-shaped seat 3021 is detachably connected to the rear side of the housing 3017, and the upper side wall of the U-shaped seat 3021 is provided with a threaded hole H31. The locking bolt 3022 is threadedly engaged with the threaded hole H31, and one end of the locking bolt extends into the U-shaped seat 3021 to clamp and lock it onto the hospital bed.

[0084] In use, the opening of the U-shaped seat 3021 can be clamped into a hospital bed or other fixed object, and then the locking bolt 3022 can be adjusted to clamp and fix it to the hospital bed or other fixed object. In this embodiment, by using the above-mentioned clamping and components, medical staff can quickly install and fix the pressure monitor 30 to the hospital bed through the U-shaped seat 3021 and the locking bolt 3022, and ensure the stability of the device position during use, reducing problems such as monitoring interruption and inconvenience in observation and operation caused by the device not being fixed.

[0085] In one embodiment of this utility model, the rear side of the housing 3017 is provided with a groove H33, the bottom wall of the U-shaped seat 3021 is engaged in the groove H33, and the inner bottom surface of the U-shaped seat 3021 is flush with the rear side of the housing 3017. Thus, when the clamping assembly 302 is installed on the housing 3017, the connection between the clamping assembly 302 and the housing 3017 is more stable and reliable, and the overall integrity is better.

[0086] In one embodiment of the present invention, the bottom wall of the U-shaped seat 3021 has a downwardly protruding retaining edge 3023, and the lower side wall of the groove H33 is provided with a downwardly recessed retaining groove H34; the top wall of the U-shaped seat 3021 has a retaining opening H32, and the upper side wall of the groove H33 is provided with an elastic buckle 3019.

[0087] When the locking edge 3023 of the U-shaped seat 3021 is inserted into the slot H34, the U-shaped seat 3021 is pressed to lock into the groove H33, and the elastic latch 3019 is locked with the slot H32.

[0088] In this embodiment, by providing a downwardly protruding locking edge 3023 on the bottom wall of the U-shaped seat 3021 and a downwardly recessed locking groove H34 on the lower side wall of the groove H33, and by providing an elastic locking buckle 3019 and a locking slot H32 to cooperate between the top wall of the U-shaped seat 3021 and the upper side wall of the groove H33, a mechanical quick assembly is achieved. This not only improves the ease of installation of the clamping component 302, but also enhances the vibration and impact resistance of the monitoring gauge 301 during use, ensuring that the device remains in a stable and fixed state during use.

[0089] Preferably, the inner surfaces of the upper and lower side walls of the U-shaped seat 3021 are provided with arc-shaped clamping grooves H30. These arc-shaped clamping grooves H30 can ensure that the U-shaped seat 3021 can adapt to clamping tubular parts, and at the same time, it can also be used to clamp planar objects, which improves the adaptability of the U-shaped seat 3021 in specific applications and makes it more flexible and convenient to use.
