Description

Technical Field

[0001] This utility model relates to the field of ventilators, and more particularly to a portable ventilator with flexible air pressure control. Background Technology

[0002] A ventilator is a medical device that assists or replaces a patient's spontaneous breathing through mechanical ventilation. It is mainly used to maintain the patient's gas exchange and vital signs. When a patient is unable to breathe spontaneously due to respiratory center depression, respiratory muscle weakness, or airway obstruction, the ventilator provides necessary support through positive pressure ventilation to ensure that oxygen enters the blood and carbon dioxide is expelled.

[0003] Traditional compressors, air tanks, and other metal and plastic components result in a large size and weight. The single pressure regulating valve is difficult to adapt to the patient's breathing rhythm, and the sealing of its tubing connections relies on rigid buckles, which are prone to leakage due to vibration or deformation, reducing the overall effectiveness. Portable ventilators with flexible air pressure control can be designed. Utility Model Content

[0004] To overcome the problem that a single pressure regulating valve is difficult to adapt to the patient's breathing rhythm, and that the sealing of its pipeline connection relies on rigid buckles, which are prone to air leakage due to vibration or deformation, thus reducing the overall effectiveness of use.

[0005] The technical solution of this utility model is as follows: a portable ventilator with flexible air pressure control, including an air box, a portable mounting plate, an air tube, a central control box, a mounting arc plate, and a flexible airbag plate; the air box is used to store gas for compression control, and a portable mounting plate for portable installation and carrying is fixed to both ends of the air box; a central control box for guiding gas pressure control is provided at the center of the top of the air box, and an air tube for delivering gas is provided at both ends of the central control box; a mounting arc plate for stabilizing the installation of the breathing mask and nasal suction device is provided above the air box; and flexible airbag plates for adjusting the shape of the airbag by air pressure changes are connected to both sides of the air box.

[0006] Preferably, a shock-absorbing plate is fixed to the bottom of the air box, and limit clips are symmetrically connected to the bottom of the shock-absorbing plate. The air box contains a micro compressor and a lithium battery pack. Air exchange slots are opened on both sides of the air box, and a display screen, control panel and buttons connected to the lithium battery pack are distributed on both sides of the air box.

[0007] Preferably, the inner side of the portable mounting plate is fitted with a shock-absorbing rubber sleeve, and several sets of mounting holes are distributed on the portable mounting plate. Several sets of extrusion rubber balls are arranged along the outer edge of the portable mounting plate, and shock-absorbing rubber damping is provided inside the extrusion rubber balls.

[0008] Preferably, the trachea is covered with an insulation sleeve, and a filling tube is connected to the trachea. A one-way valve is provided between the filling tube and the trachea. A magnetohydrodynamic valve is provided between the central control box and the trachea. Indicator lights are symmetrically provided on the top of the central control box. A flow meter and a sub-controller are provided inside the central control box. An indicator light is electrically connected to the top of the sub-controller. Breathing tubing passing through the mounting arc plate is symmetrically provided on the central control box.

[0009] Preferably, a flexible sleeve is fitted onto the breathing tubing, and symmetrical rings are provided on the flexible sleeve for connecting the breathing tubing. The inner side of the rings is provided with contacts for pressing the breathing tubing, and a pressure sensor is provided inside the contacts.

[0010] Preferably, the mounting arc plate is covered with a flexible layer, and the middle of the mounting arc plate is symmetrically provided with sealing interfaces corresponding to the breathing tubing.

[0011] Preferably, the flexible airbag plate has an airbag bag at its center that communicates with the air box, and floating sleeves are threaded around the flexible airbag plate. The floating sleeves have a positioning pin and a spring column at their center. An adjusting sleeve is fitted onto the top of the positioning pin, and a spring damper is installed inside the spring column. The outer side of the airbag bag is covered with a sealing edge.

[0012] The beneficial effects of this utility model are: 1. By combining a flexible airbag plate with a floating sleeve, the airbag shape is adaptively adjusted according to changes in air pressure, replacing the traditional rigid snap-fit ​​sealing structure. This significantly improves the sealing performance of the pipeline connection and reduces the risk of air leakage due to vibration or deformation. It is especially suitable for stable air supply in mobile scenarios. The ring and pressure sensor of the pressure-sensitive breathing tubing monitor the tubing pressure in real time. Combined with the magnetic fluid valve, the air pressure is dynamically adjusted, which can flexibly match the patient's respiratory rhythm changes, reduce patient-ventilator asynchrony, and improve ventilation comfort. The composite shock absorption system composed of shock-absorbing plates and shock-absorbing rubber sleeves effectively absorbs mechanical vibrations during equipment operation, preventing airway loosening or component damage caused by bumps. The portable installation tray integrates a squeeze rubber ball and a lightweight design, making it easy to carry and quickly disassemble, meeting the needs of multiple scenarios such as emergency rescue and transportation.

[0016] Please see Figures 1-5 This utility model provides an embodiment of a portable ventilator with flexible air pressure control, including an air box 1, a portable mounting plate 2, an air tube 3, a central control box 4, a mounting arc plate 5, and a flexible airbag plate 6; the air box 1 is used to store gas for compression control, and a portable mounting plate 2 is fixed to both ends of the air box 1 for portable installation and carrying. A central control box 4 is provided at the top center of the air box 1 for guiding gas pressure control. An air tube 3 is provided at both ends of the central control box 4 for delivering gas. A mounting arc plate 5 is provided above the air box 1 for installing a breathing mask and nasal suction device to maintain stability. Flexible airbag plates 6 are connected to both sides of the air box 1 for adjusting the shape of the airbag by changes in air pressure.

[0017] Please see Figures 2-3 In this embodiment, a shock-absorbing plate 101 is fixedly connected to the bottom of the air box 1, and a limit card 102 is symmetrically connected to the bottom of the shock-absorbing plate 101. The air box 1 is equipped with a micro compressor and a lithium battery pack. Air exchange slots 106 are opened on both sides of the air box 1. A display screen 103, a control board 104 and a button 105 connected to the lithium battery pack are distributed on both sides of the air box 1. A shock-absorbing rubber sleeve 201 is attached to the inner side of the portable mounting plate 2. Several sets of mounting holes 202 are distributed on the portable mounting plate 2. Several sets of extrusion rubber balls 203 are arranged along the outer edge of the portable mounting plate 2. The extrusion rubber balls 203 are equipped with shock-absorbing rubber damping inside.

[0018] Please see Figures 2-4In this embodiment, the trachea 3 is covered with a heat insulation sleeve 301, and a filling tube 302 is connected to the trachea 3. A one-way valve is provided between the filling tube 302 and the trachea 3. A magnetohydrodynamic valve 402 is provided between the central control box 4 and the trachea 3. Indicator lights 401 are symmetrically provided on the top of the central control box 4. A flow meter and a sub-controller are provided inside the central control box 4. The indicator lights 401 are electrically connected to the top of the sub-controller. A breathing tube 403 passing through the mounting arc plate 5 is symmetrically provided on the central control box 4. A flexible sleeve 404 is fitted on the breathing tube 403. A ring sleeve 405 for connecting the breathing tube 403 is symmetrically provided on the flexible sleeve 404. A contact point for pressing the breathing tube 403 is provided on the inner side of the ring sleeve 405. A pressure sensor is provided inside the contact point.

[0019] Please see Figure 1 and Figure 5 In this embodiment, the mounting arc plate 5 is covered with a flexible layer 501. The mounting arc plate 5 has symmetrical sealing interfaces 503 corresponding to the breathing tubing 403 in the middle. A concentration sensor 504 is fixed on the mounting arc plate 5. Several sets of slots 502 are arranged on the upper and lower parts of the mounting arc plate 5. The flexible airbag plate 6 has an airbag bag 601 connected to the air box 1 in the center. Floating sleeves 603 are threaded around the flexible airbag plate 6. The floating sleeve 603 has a positioning pin 605 and a spring column 604 in the center. An adjusting sleeve 606 is sleeved on the top of the positioning pin 605. A spring damper is provided inside the spring column 604. The outer side of the airbag bag 601 is covered with a sealing edge 602.

[0020] When in operation, the installation arc plate 5 fixes the breathing mask or nasal suction device through the flexible layer 501 and the slot 502. The micro compressor inside the air box 1 compresses the air and delivers it to the central control box 4. After the pressure is initially adjusted by the magnetic fluid valve 402, it is diverted to the flexible airbag plate 6 and the breathing tubing 403 through the air tube 3. When the patient inhales, the pressure in the breathing tubing 403 decreases, and the pressure sensor triggers the sub-controller to increase the opening of the magnetofluid valve 402, thereby increasing the air supply flow. At the same time, the airbag 601 of the flexible airbag plate 6 contracts due to the decrease in air pressure, and pushes the adjusting sleeve 606 to rebound through the spring damper of the floating sleeve 603, thereby enhancing the sealing fit of the tubing interface. During the exhalation phase, the pressure in the breathing tubing 403 increases, and the magnetohydrodynamic valve 402 automatically reduces its opening to lower the air pressure. The flexible airbag plate 6 expands as the air pressure recovers, releasing the sealing pressure and preventing excessive pressure from causing discomfort to the patient. The mounting plate 5 secures the breathing mask or nasal inhaler to the flexible layer 501 and the slot 502. Combined with the concentration sensor 504, it provides real-time feedback of oxygen concentration data to the sub-controller, dynamically optimizing the gas mixing ratio to ensure the effectiveness of the gas inhaled by the patient.

[0021] Through the above steps, the composite shock absorption system composed of the shock-absorbing plate 101 and the shock-absorbing rubber sleeve 201 effectively absorbs the mechanical vibration during equipment operation, avoiding loosening of the air passage or damage to components caused by bumps. The portable installation tray 2 integrates the extruded rubber ball 203 and a lightweight design, making it easy to carry and quickly disassemble and assemble, meeting the needs of multiple scenarios such as emergency rescue and transportation. The central control box 4 has a built-in flow meter and sub-controller, which precisely regulates the gas flow and pressure threshold through the magnetic fluid valve 402, and monitors the oxygen concentration in real time with the concentration sensor 504 to ensure ventilation safety. The design of the lithium battery pack and the heat insulation sleeve 301 ensures the continuous power supply and thermal stability of the equipment in extreme environments, reducing the failure rate.
