Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a gas-storage type synchronous ventilation diaphragm pacemaker. Background Technology

[0002] The lungs are vital respiratory organs, where gas exchange occurs in the alveoli. When the lungs are damaged, some alveoli lose their function, affecting overall lung function. In 1969, American scientist Glenn invented an implantable diaphragmatic pacemaker, primarily used to treat chronic ventilatory insufficiency. This implantable pacemaker places electrodes in the subcutaneous tissue of the neck at the diaphragmatic nerves on both sides. It automatically transmits electrical pulses unilaterally or bilaterally via electromagnetic coupling according to the respiratory rhythm, stimulating the diaphragmatic nerves to assist and improve respiratory function. In 1989, Professor Xie Bingxu of Sun Yat-sen University of Medical Sciences in my country invented an external diaphragmatic pacemaker (patent number: CN 2030488U) based on the internal diaphragmatic pacemaker. This design uses external electrode pads to stimulate the diaphragmatic nerves, causing diaphragmatic pacing to improve respiratory function. It is non-invasive and easy to operate. In 1990, Xie Bingxu and others invented a high-frequency ventilation diaphragmatic pacemaker (patent number: ZL90109631.8). This patented invention improves intrapulmonary oxygenation efficiency and reduces the degree of lung damage caused by positive ventilatory pressure. However, further improvements are needed in terms of the device's ventilation efficiency, the effectiveness of synchronized ventilation, miniaturization, and low power consumption. Utility Model Content

[0003] This invention provides a gas-storage type synchronous ventilation diaphragm pacemaker, which improves oxygen utilization efficiency and increases ventilation volume and ventilation pressure, and can still effectively achieve rehabilitation goals even when the oxygen supply channel, oxygen concentrator, or ventilator flow is insufficient.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The gas-storage type synchronized ventilation diaphragm pacemaker provided by this utility model may include an oxygen supply pipe and a control module. The oxygen supply pipe includes an inlet pipe and an outlet pipe connected by a three-way connector. The outlet pipe is equipped with a solenoid valve, and the control module controls the opening and closing of the solenoid valve. The three-way connector can be connected to a bypass pipe that communicates with the inlet and outlet pipes, and the bypass pipe is connected to a gas storage device.

[0006] Preferably, the control module can be connected to a respiratory sensor module. By detecting the patient's breathing rhythm through the sensor, the control module adjusts the frequency accordingly.

[0007] Preferably, the control module can be connected to the diaphragm electrical pulse generation module, and the output terminal of the diaphragm electrical pulse generation module is electrically connected to the diaphragm electrode plate.

[0008] Preferably, the control module can be connected to the communication module, and the communication module can be connected to the human-machine interface.

[0009] Preferably, the communication module may include a wireless communication module.

[0010] Preferably, the respiratory sensing module can be, but is not limited to, a mouth and nose breathing pressure sensor, a chest breathing sensor, an abdominal breathing sensor, or a breathing carbon dioxide concentration sensor.

[0011] Preferably, the device may also include a housing, with a control module and a solenoid valve located inside the housing, and an oxygen supply pipe passing through the housing.

[0012] Preferably, the outlet end of the three-way pipe connected to the bypass air pipe is fitted with a fixing ring, and a sealing plug is provided on one side of the fixing ring. The sealing plug and the fixing ring are connected by a plastic flap.

[0013] The beneficial effects of this utility model patent are as follows:

[0014] 1. By using bypass gas storage and synchronized ventilation, the gas valve is closed when the patient exhales, and oxygen flows to the gas storage device. When the patient inhales, the ventilation valve is opened simultaneously, which improves oxygen utilization efficiency and increases ventilation volume and ventilation pressure. Even when the oxygen supply channel, oxygen concentrator, or ventilator flow is insufficient, rehabilitation goals can still be effectively achieved.

[0015] 2. The respiratory sensing module receives and amplifies the respiratory synchronization signal and transmits it to the control module. The diaphragm electrical pulse generation module generates the voltage pulse waveform required for diaphragm pacing according to the instructions of the control module, detects the respiratory synchronization signal, and transmits it to the control module to achieve the purpose of synchronizing oxygen supply and diaphragm pulse current output, thereby achieving better therapeutic effect.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] See Figures 1-3 As shown, one embodiment of this utility model provides a gas-storage type synchronized ventilation diaphragm pacemaker, including a circuit box 1, an oxygen supply pipe 7, and an air bag 10. The oxygen supply pipe 7 includes an inlet pipe 9 and an outlet pipe 6 connected by a three-way connector 8. The outlet pipe 6 is equipped with a solenoid valve 3, and a control module 4 controls the opening and closing of the solenoid valve 3. The three-way connector 8 connects to a bypass pipe 11 that communicates with the inlet pipe 9 and the outlet pipe 6, and the bypass pipe connects to the gas storage device (i.e., the air bag 10). A cover 2 is detachably installed at the upper opening of the circuit box 1, and the solenoid valve 3, the control module 4, the diaphragm electrical pulse generation module 5, and the communication module are fixedly installed on the inner bottom of the circuit box 1.

[0025] As an optional implementation, the output terminal of the control module 4 is electrically connected to the input terminals of the solenoid valve 3 and the diaphragm electrical pulse generation module 5, respectively, and the output terminal of the diaphragm electrical pulse generation module 5 is electrically connected to the diaphragm electrode plate. The control module 4 can control the opening and closing of the solenoid valve 3, and at the same time control the diaphragm electrical pulse generation module 5 to send current to the diaphragm electrode plate.

[0026] As an optional implementation, the control module 4 can be connected to the respiratory sensing module 19. By detecting the patient's breathing rhythm through the sensor, the control module adjusts the frequency according to the patient's breathing. The respiratory sensing module can be, but is not limited to, a mouth and nose breathing pressure sensor, a chest breathing sensor, an abdominal breathing sensor, or a respiratory carbon dioxide concentration sensor.

[0027] As an optional implementation, the airbag 10 is placed on the upper surface of the lid 2. An elastic band 12 is detachably connected to the upper surface of the lid 2, passing over the airbag 10 from the upper side. The airbag 10 is connected to the three-way connector 8 via a bypass air pipe 11. Long slots 13 are formed through both sides of the lid 2. T-shaped levers 14, adapted to the long slots 13, are fixedly connected to both ends of the elastic band 12. The airbag 10 is placed on the surface of the lid 2, and then two… T-shaped levers 14 are inserted into the two elongated slots 13 and rotated to make the T-shaped levers 14 and the elongated slots 13 cross each other, preventing the T-shaped levers 14 from falling out of the elongated slots 13. At this time, the elastic band 12 is wrapped around the upper middle part of the airbag 10. By inflating the airbag 10, it expands and at the same time, the elastic band 12 is elastically stretched. When inhaling, the tension of the elastic band 12 squeezes the airbag 10, thereby increasing the oxygen delivery volume and delivery pressure.

[0028] Reference Figure 4 As shown, a retaining ring 16 is fitted on the other outlet end of the three-way interface 8. A sealing plug 18 is provided on one side of the retaining ring 16. The sealing plug 18 is connected to the retaining ring 16 by a plastic flap 17. When the gas storage device is not in use, the sealing plug 18 can be folded to block the port of the three-way interface 8, realizing multiple usage scenarios of the device.

[0029] As an optional implementation, the communication module and the control module 4 are electrically connected to each other, and the output of the communication module is electrically connected to the human-machine interface display module to receive commands from the control module. The control commands are connected to the communication module through the human-machine interface display module. The communication module (including wired or wireless communication, such as existing RS232, USB, or Bluetooth communication protocols) receives commands from the control module. The control commands can be connected to the communication module through various means, including but not limited to the display module APP or WeChat mini-program.

[0030] As an optional implementation, a fitting ring 15 is fixedly connected to the bottom surface of the cover 2. The fitting ring 15 is adapted to the inner diameter of the opening of the circuit box 1. The fitting ring 15 can be pressed into the opening of the circuit box 1 to complete the snap-fit ​​installation of the cover 2 at the opening of the circuit box 1.

[0031] Using the above structure, when in use, the box cover 2 can be removed, the gas storage device can be installed on the upper surface of the box cover 2, and the oxygen supply pipe 9, the three-way interface 8, the air inlet pipe 7 and the gas storage device can be connected. First, control the solenoid valve 3 to close, so that the oxygen in the oxygen supply pipe 9 fills the gas storage device and the gas pressure in the gas storage device reaches the standard. Then, attach the diaphragm electrode to the diaphragm. As the patient breathes, the diaphragm is stimulated, and the solenoid valve 3 is repeatedly opened and closed. During the closing cycle of the solenoid valve 3, the purpose of storing oxygen and increasing the gas pressure is achieved. When the solenoid valve 3 is open, the ventilation volume and gas pressure are increased.

[0032] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.

[0033] It should be noted that, inspired by this patent, manufacturing and selling only components other than the gas storage device, and then having patients purchase these components and use them with devices such as airbags, also constitutes an infringement of this patent right.
