Description

Technical Field

[0001] This invention belongs to the field of ventilator tubing technology, and more specifically, relates to an intelligent early warning device for condensate in ventilator tubing based on impedance spectroscopy. Background Technology

[0002] A ventilator is a medical device used to assist or replace a patient's breathing. When a patient's ability to breathe independently is impaired or lost, it delivers oxygen and a gas mixture to the patient's lungs to maintain normal respiratory vital signs. Currently, the oxygen and gas mixture produced by the ventilator need to be delivered to the patient's respiratory organs through the ventilator tubing. When air flows within the ventilator tubing, the temperature difference between the inside and outside of the tubing and the influence of the humidifier cause water vapor to easily accumulate and condense into water droplets. Therefore, traditional ventilator tubing has a water collection bottle installed in a low-lying area, allowing condensate to flow into the bottle by gravity for storage. However, traditional ventilator tubing water collection bottles lack real-time monitoring of condensate accumulation and overflow alarms. This allows condensate to accumulate over time and overflow into the ventilator tubing, causing reflux into the patient's lungs and leading to infection, seriously damaging the patient's respiratory health. Summary of the Invention

[0006] In at least some embodiments, the manifold is a Y-shaped three-way tubular structure.

A manifold plate is welded to the inner side of the bottom pipe opening of the Y-shaped three-way tubular structure. The upper side of the manifold plate is a conical structure with a centripetal inclination. A through hole structure is provided at the center of the conical structure of the manifold plate, and the diameter of the through hole of the manifold plate is smaller than the diameter of the sealing ball.

[0007] In at least some embodiments, the liquid collection bottle is a cylindrical structure with an open top. The outer side of the cylindrical structure of the liquid collection bottle is provided with six sets of semi-circular through grooves near the bottom. The semi-circular through grooves are arranged in a ring array around the vertical central axis of the liquid collection bottle. The bottom of the cylindrical structure of the liquid collection bottle is a conical structure. The top of the conical structure at the bottom of the liquid collection bottle is provided with a threaded through hole that runs vertically through the bottom.

[0008] In at least some embodiments, the sealing tube is a cylindrical structure that runs vertically through the top and bottom. Four sets of limiting sliders are welded to the outer side of the sealing tube. A threaded structure is provided on the outer side of the sealing tube near the top.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, an impedance sensor detects changes in the liquid impedance of condensate in the condensate bottle in real time. The liquid impedance value is transmitted to the control unit of the condensate detection alarm via a signal transmission line for identification and analysis of the degree of condensate accumulation. The control unit then controls the sounder to issue alarms based on the data measured by the impedance sensor, indicating different degrees of condensate accumulation. This achieves real-time monitoring and overflow alarm functions for the degree of condensate accumulation in the ventilator's air delivery line, reminding medical staff to promptly drain the condensate from the condensate bottle. This reduces the risk of condensate overflowing into the air delivery line and refluxing into the patient's respiratory organs, causing infection and damage. It strengthens the safety defense for the patient's treatment process and significantly improves the overall safety of the ventilator's air delivery line.

[0014] 2. In this invention, the threaded engagement transmission structure formed by the engagement of the inner side thread of the rotating sleeve with the outer side thread of the sealing cylinder operates, allowing the rotating sleeve to drive the sealing cylinder to move vertically upward along the groove structure of the drain shell. This causes the silicone sealing sleeve bonded to the inner side of the sealing cylinder to detach from the semi-circular through-groove structure of the effluent bottle, thus draining the condensate. This eliminates the need for the traditional method of completely removing the effluent bottle and the ventilator's air delivery line for drainage. The condensate in the effluent bottle is drained without the need for complete removal of the effluent bottle, preventing oxygen from being exposed and overflowing from the ventilator's air delivery line and preventing condensate from dripping out and contaminating the ward's hygiene.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] like Figures 1-9 As shown, this invention provides an intelligent early warning device for condensate in ventilator tubing based on impedance spectroscopy, including a reservoir 1; a lid 2 is installed on the top of the reservoir 1, and a through hole is provided at the top of the lid 2, through which an infusion tube 3 is inserted; it also includes a condensate accumulation monitoring device 7; the condensate accumulation monitoring device 7 includes a manifold 701, a drain shell 702, a rotating sleeve 703, a condensate bottle 704, an impedance sensor 705, a drain interface 706, a manifold plate 707, a permeable shell 708, a sealing ball 709, a limiting slider 710, a sealing cylinder 711, a sealing sleeve 712, and a threaded sleeve 713; a manifold 701 is welded to the outer side of the manifold 707, and a permeable shell 708 is welded to the bottom end of the manifold 701; the permeable shell 709... A sealing ball 709 is placed on the inner side of the 8; a manifold 701 is installed at the top of the liquid collection bottle 704, a drain port 706 is installed at the bottom of the liquid collection bottle 704, an impedance sensor 705 is installed at the bottom of the liquid collection bottle 704, a signal transmission line 5 is installed at the bottom of the impedance sensor 705, the other end of the signal transmission line 5 is connected to a liquid collection detection alarm 4, the impedance sensor 705 is bonded to a threaded sleeve 713, a rotating sleeve 703 is rotatably connected to the outer side of the liquid collection bottle 704 near the top, a drain shell 702 is welded to the outer side of the liquid collection bottle 704 near the bottom; a sealing cylinder 711 is slidably connected to the inner side of the drain shell 702, a limit slider 710 is welded to the outer side of the sealing cylinder 711, and the sealing cylinder 711 is bonded to a sealing sleeve 712.

[0027] In this embodiment of the invention, the liquid accumulation detection alarm 4 includes a control unit 401, a display screen 402, a speaker 403, a signal transmission interface 404, and a USB power interface 405. The speaker 403 and the signal transmission interface 404 are mounted on the front side of the control unit 401 near the right end. A signal transmission line 5 is mounted on the signal transmission interface 404. The display screen 402 is mounted on the front side of the control unit 401 near the left end. The display screen 402 displays the data values ​​returned by the impedance sensor 705 in real time. The USB power interface 405 is mounted on the left side of the control unit 401. The USB power interface 405 connects to the USB data cable to power the controller 401. The controller 401 receives the monitoring data of the condensate from the impedance sensor 705 through the signal transmission interface 404. The controller 401 identifies the monitoring data of the condensate. If the condensate accumulation value reaches different warning values, the controller 401 controls the speaker 403 to emit alarm sounds of different frequencies according to the size of the warning value, to warn medical staff that the condensate is about to reach the overflow level and to perform the condensate drainage operation, effectively avoiding the situation of condensate overflowing and backflowing in the gas supply pipe 6.

[0028] In this embodiment of the invention, the manifold 701 is a Y-shaped three-way tubular structure. Gas delivery pipes 6 are installed at the two sets of openings at the top of the Y-shaped three-way tubular structure of the manifold 701. A manifold plate 707 is welded to the inner side of the bottom opening of the Y-shaped three-way tubular structure of the manifold 701. The upper side of the manifold plate 707 is a concentrically inclined conical structure. A through-hole structure is provided at the center of the conical structure of the manifold plate 707, allowing condensate to flow through the conical structure of the manifold plate 707 and concentrate towards the through-hole, preventing condensate from accumulating on the upper side of the manifold plate 707. The diameter of the through-hole of the manifold plate 707 is smaller than the diameter of the sealing ball 709. When the liquid collection bottle 704 is tilted and inverted, the sealing ball 709 rolls down to the through-hole of the manifold plate 707 under gravity to seal it, preventing condensate from flowing into the gas delivery pipe 6 through the Y-shaped three-way tubular structure of the manifold 701.

[0029] In this embodiment of the invention, the liquid collection bottle 704 is a cylindrical structure with an open top. The outer side of the cylindrical structure of the liquid collection bottle 704 is provided with six sets of semi-circular through grooves near the bottom. The semi-circular through grooves are arranged in a ring array around the vertical central axis of the liquid collection bottle 704. The bottom of the cylindrical structure of the liquid collection bottle 704 is a conical structure, so that during the condensation discharge process in the liquid collection bottle 704, the condensate is guided by gravity along the inclined surface of the conical structure to the semi-circular through grooves of the liquid collection bottle 704, avoiding the accumulation of condensate at the bottom of the liquid collection bottle 704, and ensuring that the condensate is discharged from the liquid collection bottle 704 by gravity. The top of the conical structure at the bottom of the liquid collection bottle 704 is provided with a threaded through hole that runs vertically through the bottom.

[0030] In this embodiment of the invention, the sealing cylinder 711 is a cylindrical structure that runs vertically through the cylinder. Four sets of limiting sliders 710 are welded to the outer side of the sealing cylinder 711. A threaded structure is provided near the top of the outer side of the sealing cylinder 711. An annular groove is provided near the bottom of the inner side of the sealing cylinder 711. A sealing sleeve 712 is bonded to the inner side of the annular groove of the sealing cylinder 711. The sealing sleeve 712 is made of silicone. When the sealing sleeve 712 bonded to the sealing cylinder 711 is horizontally aligned with the six sets of semi-circular through grooves of the liquid collection bottle 704, the elastic sealing properties of the silicone material of the sealing sleeve 712 are used to tightly fit the outer side of the liquid collection bottle 704 and seal the six sets of semi-circular through grooves of the liquid collection bottle 704, thereby preventing condensate from leaking out of the liquid collection bottle 704.

[0031] In this embodiment of the invention, the inner side of the rotating sleeve 703 is provided with a threaded structure near the bottom. The inner side of the rotating sleeve 703 is threadedly engaged with the outer side of the sealing cylinder 711. During the rotation of the rotating sleeve 703, the sealing cylinder 711 is driven to move up and down along the outer side of the liquid collection bottle 704 through the thread, completing the sealing and opening work of the sealing cylinder 711 at the semi-circular through groove of the liquid collection bottle 704. When the rotating sleeve 703 drives the sealing cylinder 711 to move upward away from the semi-circular through groove of the liquid collection bottle 704, the condensate is discharged into the interior of the drain shell 702 through the semi-circular through groove of the liquid collection bottle 704. The condensate flows into the delivery pipe 3 from the drain port 706 at the bottom of the drain shell 702 and is discharged into the storage tank 1. This prevents the gas passage structure of the gas delivery pipe 6 from being exposed due to the complete removal of the liquid collection bottle 704, and ensures stable gas delivery by the gas delivery pipe 6.

[0032] In this embodiment of the invention, the inner side of the drain shell 702 is provided with four sets of grooves near the top. The grooves are arranged in a circular array around the vertical central axis of the drain shell 702. The four sets of limiting sliders 710 welded to the outer side of the sealing cylinder 711 are respectively embedded in the four sets of grooves of the drain shell 702. The four sets of grooves of the drain shell 702 limit the rotation of the sealing cylinder 711 through the limiting sliders 710, so as to prevent the rotating sleeve 703 from driving the sealing cylinder 711 to rotate synchronously, and ensure that the sealing cylinder 711 performs stable vertical up and down movement.

[0033] In this embodiment of the invention, a threaded sleeve 713 is bonded to the outer side of the impedance sensor 705. The threaded sleeve 713 is threadedly engaged in the threaded through hole of the liquid collection bottle 704. The impedance sensor 705 can be detached from the liquid collection bottle 704 by screwing on the thread. During the disinfection operation of the liquid collection bottle 704, the impedance sensor 705 and the liquid collection bottle 704 can be removed and separated separately. The impedance sensor 705 monitors the change of liquid impedance value in the pipeline in real time and automatically identifies the degree of condensate accumulation.

[0034] In this embodiment of the invention, the permeable shell 708 is a cylindrical structure with an opening on the upper side. The outer side of the permeable shell 708 is provided with fifteen sets of through grooves. When the sealing ball 709 falls to the bottom of the cylindrical structure of the permeable shell 708 by gravity, the condensate flows into the liquid collection bottle 704 through the through grooves of the permeable shell 708 for centralized collection.

[0035] The specific usage and function of this embodiment are as follows: In this invention, during the monitoring and early warning of condensate accumulation, oxygen and mixed gases produced by respiration pass through the gas delivery pipe 6, where condensate droplets form inside. These droplets, along the Y-shaped structure of the manifold 701, flow under gravity to the manifold plate 707. The condensate then passes through the through-holes of the manifold plate 707 and the through-groove of the permeable shell 708, falling into the collection bottle 704. The condensate accumulates in the collection bottle 704, while the detection end of the impedance sensor 705 is immersed in the condensate. The impedance sensor 705 detects the impedance value of different condensate volumes in real time and transmits the impedance data to the signal transmission interface 404 via the signal transmission line 5. The control unit 401 receives the impedance data through the signal transmission interface 404 and analyzes the condensate impedance data to determine the water volume in the collection bottle 704. When the water volume in the collection bottle 704 reaches different warning levels, the control unit 401 controls the speaker 403 via a wire to emit sound alarms of different frequencies, alerting medical personnel to drain the condensate. During water drainage operations, medical staff hold the drain housing 702 with one hand and rotate the rotating sleeve 703 with the other. Because the inner thread of the rotating sleeve 703 is engaged with the outer thread of the sealing cylinder 711, the rotation of the rotating sleeve 703 causes the sealing sleeve 712, which is adhered to the inner side of the sealing cylinder 711, to detach upwards from the six sets of semi-circular grooves on the outer side of the collection bottle 704. The condensate in the collection bottle 704 flows into the inside of the drain housing 702 through the semi-circular grooves, and then flows out from the bottom of the drain housing 702. The drain port 706 installed at the end flows into the infusion pipe 3. The condensate flows into the storage tank 1 through the infusion pipe 3. When the condensate is completely discharged from the collection bottle 704, the rotating sleeve 703 is manually rotated in the reverse direction. During the reverse rotation of the rotating sleeve 703, the sealing sleeve 712 bonded to the inner side of the sealing cylinder 711 moves downward until the sealing sleeve 712 is horizontally aligned with the six sets of semi-circular through grooves on the outer side of the collection bottle 704. The sealing sleeve 712 seals the collection bottle 704, and the condensate gathers in the collection bottle 704 again.

[0036] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies; any method that achieves the desired effect can be implemented. The control unit 401, display screen 402, speaker 403, signal transmission interface 404, USB power interface 405, and impedance sensor 705 mentioned above are all common commercially available components. Upon purchase and use, simply connect them according to the instruction manual provided; therefore, further details are omitted here.
