Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a pressure loss warning artificial nose device.

Background Art

[0002] A disposable breathing filter (also called an artificial nose) is an auxiliary consumable commonly used in devices such as anesthesia machines, ventilators, and pulmonary function testing devices. It filters bacteria and dust, reduces the amount of particulate matter inhaled or exhaled by patients, has excellent heat preservation and moisture retention properties, and mimics the natural temperature and humidity conditions of the upper airway to provide a suitable breathing environment for patients. The ventilation airway resistance is appropriate and does not increase the patient's breathing difficulty. At the same time, some composite breathing filters can also increase the moisture content and temperature of the gas sent to the airway.

[0003] However, during surgery and support by a ventilator, there is pressure gas in the ventilation tube, and each interface is likely to loosen or fall off, so the connection tube including the artificial nose may come off from the air supply device. If the situation where the airway tube comes off cannot be detected in a timely manner, the patient's life safety will be seriously threatened and may even lead to brain death. As an essential filter in the breathing tube, by adding element sensing components such as air pressure and an alarm device to the artificial nose, the risk after the breathing tube falls off can be effectively warned and the patient's safety can be improved. However, currently, there is no tube detachment alarm device for the artificial nose, and it is impossible to monitor whether the artificial nose falls off, further threatening the patient's life safety.

[0004] Therefore, in order to address the above technical problems, a pressure loss warning artificial nose device is designed by installing signal sensing and transmission components and an audio alarm system on the filter side away from the patient-side interface to monitor the air pressure inside the artificial nose in real time. The technical problem that those skilled in the art should solve is to alarm the detachment of the artificial nose while not affecting the cleanliness of the gas entering the patient side.

[Brief explanation of the drawing]

[0017] To more clearly explain the technical solutions in the present invention or the prior art, the following briefly introduces the drawings necessary for use in the embodiments. Clearly, the drawings in the following description are merely a number of embodiments of the present invention, and those skilled in the art can obtain other drawings based on these without any further creative effort.

[0018] [Figure 1] This is a schematic diagram of the overall structure of the pressure loss alarm artificial nose device disclosed in the embodiment of the present invention. [Figure 2] This is a schematic diagram of the connection structure between the signal sensing and transmission component and the voice alarm system of the pressure loss alarm artificial nose device disclosed in the embodiment of the present invention. [Modes for carrying out the invention]

[0019] The technical solutions in embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments. Clearly, the embodiments described are only a part of the embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on embodiments of the present invention without creative effort are all within the scope of the present invention.

[0020] This invention aims to provide a pressure loss alarm artificial nose device that monitors the air pressure inside the artificial nose in real time by installing signal sensing and transmission components and an audio alarm system on the filter side, away from the patient-side interface. It alarms when the artificial nose falls out, without affecting the cleanliness of the gas entering the patient's side.

[0021] Referring to Figures 1 and 2, the pressure loss alarm artificial nose device disclosed in the embodiment of the present invention includes at least a control system, an artificial nose body, and a machine-side interface 1 installed at one end of the artificial nose body and communicating with the artificial nose body, wherein the machine-side interface 1 communicates with a gas supply unit, and a patient-side interface 4 is installed at the other end of the artificial nose body, which communicates with the artificial nose body, and a filtration membrane device 3 for filtering the gas supplied by the air supply unit is installed inside the artificial nose body, and a signal sensing / transmission component 5 and an audible alarm system 6 are installed inside the artificial nose body between the filtration membrane device 3 and the machine-side interface 1, the signal sensing / transmission component 5 and the audible alarm system 6 are connected to each other, and the control system is configured to receive a signal from the signal sensing / transmission component 5 and control the audible alarm system 6 to sound an alarm. By installing the signal sensing and transmission component 5 and the voice alarm system 6 between the filtration membrane device 3 and the machine-side interface 1, and by installing the signal sensing and transmission component 5 and the voice alarm system 6 between the filtration membrane device 3 and the patient-side interface 4, the problem of respiratory gas contamination by volatile substances emitted from the signal sensing and transmission component 5 and the voice alarm system 6 can be effectively avoided, and the cleanliness of the gas on the patient side can be ensured. Furthermore, by installing the signal sensing and transmission component 5 and the voice alarm system 6, the air pressure inside the artificial nose can be monitored in real time, and an alarm can be sounded if the machine-side interface 1 becomes detached from the air supply unit or if the patient-side interface 4 becomes detached from the patient-side air supply tube.

[0022] Referring to Figures 1 and 2, in one embodiment, the signal sensing and transmission component 5 includes a pressure sensor 7 for acquiring a pressure signal, an integrated power amplifier audio chip 8 for broadcasting audio, and a signal output device 9 for outputting a signal; the audio alarm system 6 includes a signal receiving device 10 for receiving a signal from the signal output device 9, and a small speaker 11 for receiving a signal from the signal receiving device and outputting broadcast audio.

[0023] Referring to FIGS. 1 and 2, as one embodiment, the control system is configured to set a pressure threshold value. The detected pressure value by the pressure sensor 7 is transmitted to the control system and compared with the set pressure threshold value. When the pressure value is smaller than the set pressure threshold value, the control system controls the small speaker 11 to output broadcast voice.

[0024] Note that the pressure sensor 7 can detect the air pressure inside the artificial nose body, and there is broadcast voice inside the integrated power amplifier voice chip 8. When the pressure sensor 7 detects that the data result is lower than the pressure threshold value, the control system issues an alarm signal and outputs the signal through the signal output device 9. The signal receiving device 10 receives the input signal from the signal output device 9 and outputs the broadcast voice to the small speaker 11. The specific operating principle is as follows. The signal sensing and transmission component 5 senses the change in the air pressure of the breathing tube, records voice prompts such as "help" in the integrated power amplifier voice chip 8, and transmits a signal to the small speaker 11 through the control system to output the corresponding voice. When the gas tube on the artificial nose falls off, an early warning is issued.

[0025] Referring to FIGS. 1 and 2, as one embodiment, inside the artificial nose, on the side close to the mechanical side interface 1, a humidity sensor for detecting humidity and a humidifier for humidifying the inside of the artificial nose are installed. The humidity sensor and the humidifier are communicatively connected to the control system, and the humidity sensor monitors the humidity of the gas inside the artificial nose in real time. When it is detected that the humidity is insufficient, the control system immediately activates the humidifier to replenish moisture and avoid dryness of the airway mucosa and an increase in the viscosity of sputum. When the sensor detects that the humidity is too high, the control system can automatically reduce the power of the humidifier or stop its operation to prevent the growth of bacteria due to the accumulation of condensation and the occurrence of abnormal respiratory resistance.

[0026] Referring to FIGS. 1 and 2, as one embodiment, the pressure threshold value is 0.2 kPa to 0.3 kPa.

[0027] Referring to Figures 1 and 2, in one embodiment, the artificial nose body is equipped with a carbon dioxide concentration interface 2 on the side closer to the machine-side interface 1 for detecting the patient's end-tidal CO2 concentration, allowing for real-time capture of the patient's end-tidal CO2 concentration and directly reflecting alveolar ventilation efficiency and pulmonary blood flow status. The monitoring data helps determine whether the endotracheal tube is positioned correctly, thereby reducing the risks of artificial airway management.

[0028] Referring to Figures 1 and 2, in one embodiment, the filtration membrane device 3 is attached to the inner wall of the artificial nose body, making it easy to replace the filtration membrane device 3.

[0029] Furthermore, by installing a connection groove on the inner wall of the artificial nose body for attaching the filtration membrane device 3, the connection between the filtration membrane device 3 and the inner wall of the artificial nose body can be achieved.

[0030] Referring to Figures 1 and 2, in one embodiment, the inside of the filtration membrane device 3 is a polypropylene fiber membrane.

[0031] Referring to Figures 1 and 2, in one embodiment, both the signal sensing and transmission component 5 and the voice alarm system 6 are installed on the inner wall of the artificial nose body, and the signal sensing and transmission component 5 and the voice alarm system 6 are securely fixed together.

[0032] Any adaptive modifications made in response to actual needs are within the scope of protection of this invention.

Therefore, the embodiments should be considered in all respects as illustrative and non-limiting.
