[0024] Embodiment:
[0025] Please refer to Figures 1-3 , this embodiment provides an unplanned extubation warning system for ICU patients, which includes an unplanned extubation warning system for ICU patients provided by the present invention, which includes a first monitoring ring 1, a second monitoring ring, and a connecting ring 2. The first monitoring ring 1 and the second monitoring ring are connected by the connecting ring 2; sealing rings are provided at the ends of the first monitoring ring 1 and the second monitoring ring that are away from each other; a cavity is provided inside the connecting ring 2, and two arc-shaped films 5 are oppositely provided on the connecting ring 2, and inductive sheets 6 are provided on the arc-shaped films 5; an air port and a valve are provided on the connecting ring 2.
[0026] Existing monitoring devices cannot accurately monitor the intubation status of patients. In the present invention, a first monitoring ring 1, a second monitoring ring, and a connecting ring 2 are provided. The two connecting nozzles are fixed by the first monitoring ring 1 and the second monitoring ring. With a cavity provided inside the connecting ring 2, the connection status can be monitored through air pressure changes. If the tube is removed or the connection is unstable, a warning can be issued through the change in the connection status of the induction sheets 6 provided on the two arc-shaped membranes 5 caused by the air pressure change, effectively realizing the monitoring of the connection status. Through the arc-shaped membrane 5, it can be set to inflate the cavity through the air port to separate the induction sheets 6 on the two arc-shaped membranes 5 or to deflate to make the induction sheets 6 on the two arc-shaped membranes 5 contact, determining the sealing status of the cavity. When the contact status changes, it can be determined that the tube has been removed or there is a leakage, and a warning is issued. It can be understood that the two induction sheets 6 can be set in the structure of common contact induction electric sheets on the market, and an alarm is given through an externally connected controller and a speaker; the arc-shaped membrane 5 is made of a material that can deform and has a recovery ability.
[0027] In some embodiments of the present invention, the concave sides of the two arc-shaped membranes 5 are arranged opposite to each other, and the induction sheets 6 are arranged at the concave parts of the arc-shaped membranes 5. By deflating, the two arc-shaped membranes 5 can be brought closer and the two induction sheets 6 can be made to contact. When there is a leakage or the tube is removed, gas enters the cavity, causing the two induction sheets 6 to separate and an alarm to be issued. The arc-shaped membrane 5 is made of rubber material.
[0028] In some embodiments of the present invention, the cavity is arranged in the middle of the connecting ring 2. The cavity includes an annular groove 3 and an induction groove 4, and the induction groove 4 is arranged at the bottom of the annular groove 3; the two arc-shaped membranes 5 are arranged on both sides of the induction groove 4. Through the arrangement of the annular groove 3 and the induction groove 4, the connecting tube will not cause miscontact with the induction sheet 6 due to dislocation, making the monitoring structure more accurate.
[0029] In some embodiments of the present invention, the sealing ring includes an inflation ring 7, and sealing strips 8 are arranged on both sides of the inflation ring 7. The sealing strips 8 on both sides are inclined towards the side close to the inflation ring 7. Through the setting of inflating the inflation ring 7, combined with the sealing strips 8 inclined inwards on both sides, connecting tubes of different sizes can be fixed and sealed well, with stronger adaptability and can effectively ensure the sealing effect.
[0030] In some embodiments of the present invention, the valve includes a through port 9, an opening and closing valve is arranged at the inner end of the through port 9, and a sealing film 10 is arranged at the outer end of the through port 9. The setting of the sealing film 10 enables the through port 9 to be effectively closed by the sealing film 10 after deflation, preventing external gas from entering. It can be understood that one side of the sealing film 10 is fixedly connected.
[0031] In some embodiments of the present invention, the opening and closing valve includes a sealing plate 11, and a return spring 12 is connected to the sealing plate 11. The return spring 12 is connected to the inner side of the connecting ring 2. The sealing plate 11 is provided with the return spring 12, so that when the air extraction device is inserted, it can open and press against the sealing plate 11 to extract air from the cavity, and it can automatically close after the air extraction device is pulled out. It can be understood that the air extraction device can be selected with a common structure on the market.
[0032] In summary, the embodiment of the present invention provides an early warning system for unplanned extubation of ICU patients, which includes a first monitoring ring 1, a second monitoring ring and a connecting ring 2. The first monitoring ring 1 and the second monitoring ring are connected through the connecting ring 2; sealing rings are provided at the ends of the first monitoring ring 1 and the second monitoring ring that are away from each other; a cavity is provided inside the connecting ring 2, and two arc-shaped membranes 5 are oppositely arranged on the connecting ring 2, and induction sheets 6 are arranged on the arc-shaped membranes 5; an air port and a valve are provided on the connecting ring 2. By setting the first monitoring ring 1, the second monitoring ring and the connecting ring 2, the two connecting pipes are fixed by the first monitoring ring 1 and the second monitoring ring. With a cavity provided inside the connecting ring 2, the connection state can be monitored through air pressure changes. If the situation of extubation or unstable connection occurs, an early warning can be given through the change in the connection state of the induction sheets 6 arranged on the two arc-shaped membranes 5 caused by the air pressure change, effectively realizing the monitoring of the connection state.
[0033] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
