Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to respiratory physiotherapy devices. Background Art

[0002] A ventilator, also known as a breathing machine or respiratory support device, is a medical device used to assist or control a patient's breathing. It is mainly used to treat various conditions that cause difficulty breathing or inability to breathe independently, such as acute respiratory distress syndrome, chronic obstructive pulmonary disease, severe pneumonia, support during anesthesia, etc. The ventilator helps or completely replaces the patient's natural breathing process by delivering a predetermined amount of gas to the patient's airway.

[0003] In the related art, the functions of ventilators are relatively single, usually limited to providing basic ventilation support. Since the specific conditions and treatment needs of different patients vary, it is difficult for a single-function ventilator to meet the personalized treatment requirements of all patients.

This respiratory physiotherapy device can flexibly select and combine different modules according to the specific needs of patients to achieve personalized treatment plans.

[0040] As an effective means to artificially replace the function of autonomous ventilation, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment and first aid resuscitation, and play a very important role in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and extend the lives of patients. In related technologies, the functions of ventilators are relatively single, usually limited to providing basic ventilation support. The specific conditions and treatment requirements of different patients vary, and single-function ventilators are difficult to meet the personalized treatment requirements of all patients.

[0041] Based on this, an embodiment of the present application provides a respiratory physiotherapy device that can solve the above technical problems. The respiratory physiotherapy device provided by an embodiment of the present application will be introduced in detail below with reference to the accompanying drawings.

[0042] Refer to Figures 1 to 7 As shown, the respiratory physiotherapy device provided by an embodiment of the present application includes a main unit 100, a water tank 200, an oxygen mixing module 300, and a titration module 400; the main unit 100 is provided with a first air inlet 110 and a first air outlet 120 communicated with the first air inlet 110; the water tank 200 is detachably connected to the main unit 100; the water tank 200 has a second air inlet 210 communicated with the first air outlet 120; the oxygen mixing module 300 is detachably connected to the main unit 100; the oxygen mixing module 300 is provided with an oxygen connector and an oxygen assembly hole 310, the oxygen connector is used to connect to an oxygen supply device, and the oxygen assembly hole 310 is used to dock with the first air inlet 110; the titration module 400 is detachably connected to the main unit 100, and the titration module 400 is used to monitor the respiratory parameters of patients.

[0043] Understandably, by detachably connecting the oxygen mixing module 300 to the main unit 100, the oxygen mixing module 300 can deliver oxygen from the oxygen supply device to the main unit 100 at different concentrations and flow rates. By regulating the mixing ratio of air and oxygen, corresponding oxygen concentration gases can be provided for patients. For example, for patients with weak respiratory function who require high-oxygen support, the oxygen content can be increased; for mild cases, the oxygen content can be reduced to make the mixed gas close to natural air, meeting diverse respiratory support needs and enhancing the pertinence and effectiveness of treatment. A blower is provided inside the main unit 100. The blower forms positive-pressure gas by compressing air, which is humidified by the water tank 200 and then delivered to the human body through a pipeline and a face mask, so that a certain positive pressure is maintained in the patient's respiratory tract during inhalation, helping the patient open the collapsed airway, making it easier for air to enter the lungs, increasing alveolar ventilation, preventing sleep syndromes such as apnea and hypoventilation, and assisting the patient to breathe better. The mixed gas coming out of the first air outlet 120 of the main unit 100 enters the water tank 200 through the second air inlet 210. Using the principle of heating and evaporation, the water in the water tank 200 forms water vapor and contacts the gas to achieve gas humidification, protecting the respiratory mucosa from damage and inflammation caused by inhaling dry gas; preventing the secretion from drying and hardening, maintaining the patency of the respiratory tract, and reducing the risk of blockage; also improving the user's comfort, reducing discomfort such as dry throat and coughing, enhancing the acceptance of the respiratory therapy device, and making the user more adaptable to long-term use of the respiratory therapy device. By means of the titration module 400, the respiratory parameters of the patient, such as respiratory rate, gas pressure, and gas flow rate, are monitored to accurately match the most suitable respiratory support intensity for the patient, which can not only ensure the patency of the airway and prevent problems such as apnea, but also avoid discomfort or injury caused by excessive pressure to the patient, help the patient find a better treatment pressure level, improve sleep quality and treatment effect, and make the respiratory support more accurate, more comfortable, and more effective. This respiratory therapy device can flexibly select and combine different modules according to the specific needs of the patient to achieve a personalized treatment plan.

[0044] Refer to Figure 7As shown, in one embodiment, the titration module 400 includes a pressure sensor for monitoring gas pressure. The pressure sensor can be disposed at the first air outlet 120. By detecting the pressure of the mixed gas, it can accurately match the most suitable breathing support intensity for the patient, which can not only ensure smooth airway and prevent problems such as apnea, but also avoid discomfort or injury caused by excessive pressure to the patient. In one embodiment, the titration module 400 includes a flow sensor for monitoring gas flow. The flow sensor can be disposed at the first air inlet 110 of the host 100. In this way, the flow rate of the oxygen input to the host 100 can be adjusted according to different stages of the patient. For example, for critically ill patients, the flow rate of the input oxygen can be increased; for mildly ill patients, the flow rate of the input oxygen can be decreased, helping the patient find a better treatment pressure level, improving sleep quality and treatment effect, and making the breathing support more accurate, more comfortable and more effective.

[0045] Refer to Figures 1 to 7 As shown, in some embodiments, a panel 130 is provided on the host 100. The host 100 can receive the monitoring data of the flow sensor and the pressure sensor and display it through the panel 130. In some embodiments, the panel 130 can be a touch screen or a high-definition display screen, and the host 100 can be connected to an external input device. The user can perform human-computer interaction with the host 100 through the input device and the panel 130.

[0046] Refer to Figures 1 to 7 As shown, in one embodiment, the host 100 is provided with a first communication interface, and the titration module 400 is provided with a second communication interface 410. The host 100 and the titration module 400 are communicatively connected through the first communication interface and the second communication interface 410. Through the communication connection between the two, the data monitored by the pressure sensor and the flow sensor can be fed back to the host 100 and displayed through the panel 130.

[0047] Refer to Figure 9 As shown, in one embodiment, the oxygen connector includes a high-pressure oxygen connector 320. The high-pressure oxygen connector 320 is used to transport the high-pressure oxygen output by the oxygen supply device to the first air inlet 110. The high-pressure oxygen inlet can be specifically connected to the high-pressure oxygen output port of the oxygen supply device, so as to specifically transfer the high-pressure oxygen into the host 100, which is convenient for effectively treating patients with more severe respiratory diseases and higher requirements for oxygen flow rate and concentration. In some embodiments, the high-pressure oxygen connector 320 can be a quick-release connector, including but not limited to any one of a snap connector, a threaded connector, etc.

[0048] Refer to Figure 9As shown, in one embodiment, the oxygen connector includes a low-pressure oxygen connector 330, which is used to transport the low-pressure oxygen output by the oxygen supply device to the first intake hole 110. The low-pressure oxygen inlet can be specifically connected to the low-pressure oxygen output port of the oxygen supply device, so as to specifically transfer the low-pressure oxygen into the main unit 100, facilitating the effective treatment of patients with relatively mild respiratory diseases and relatively low requirements for oxygen flow and concentration.

[0049] In actual use, different patients have different requirements for oxygen pressure and oxygen concentration. Therefore, according to the actual usage requirements, high-pressure oxygen or low-pressure oxygen can be introduced into the main unit 100, and the high-pressure oxygen and low-pressure oxygen are supplied independently, which is beneficial for targeted treatment of patients with different degrees of illness, can improve the oxygen utilization rate, reduce unnecessary resource waste, and enhance economic efficiency.

[0050] As Figure 6 shown, in some embodiments, the oxygen mixing module 300 is provided with an oxygen assembly hole 310, and the oxygen assembly hole 310 is docked with the first intake hole 110 on the main unit 100.

[0051] In one embodiment, the oxygen mixing module 300 further includes an oxygen delivery pipeline and a switching valve arranged on the oxygen delivery pipeline. The switching valve is connected to the high-pressure oxygen connector 320 and is also connected to the low-pressure oxygen connector 330. It can be understood that the oxygen mixing module 300 further includes a controller. By receiving external working instructions, such as instructions from the panel 130 of the main unit 100, the controller can control the switching valve for switching control. That is, when it is necessary to introduce high-pressure oxygen into the main unit 100, the controller controls the switching valve to open the high-pressure oxygen inlet and simultaneously close the low-pressure oxygen inlet; when it is necessary to introduce low-pressure oxygen into the main unit 100, the controller controls the switching valve to open the low-pressure oxygen inlet and simultaneously close the high-pressure oxygen inlet. Through this setting, the respiratory physiotherapy device can meet the needs of patients with different treatment requirements. Optionally, the above-mentioned controller can be, but is not limited to, any one of PLC, microcontroller chips, etc. The switching valve can be, but is not limited to, a two-way reversing solenoid valve, etc.

[0052] In some embodiments, an oxygen connector is connected to a control valve. A first communication interface is provided on the main unit 100, and a third communication interface 340 is provided on the oxygen mixing module 300. The oxygen mixing module 300 and the main unit 100 are communicatively connected through the third communication interface 340 and the first communication interface, enabling the main unit 100 and the oxygen mixing module 300 to work together. For example, the concentration and flow rate of the input oxygen can be changed on the panel 130 of the main unit 100, and this signal can be transmitted to the oxygen mixing module 300, thereby enabling the opening degree of the control valve to be adjusted, so as to adjust the oxygen flow rate or concentration input by the oxygen connector, and thus more accurately control the flow rate, concentration, etc. of the mixed gas output to the patient, improving the treatment effect. It can be understood that the target oxygen flow rate and the target oxygen concentration are set by the user, such as through a human-machine interface composed of an input device and the panel 130, and the user sends a control signal to the control valve through the human-machine interface.

[0053] For example, in one embodiment, both the first communication interface and the third communication interface 340 are provided as plug-in ports. For example, the first communication interface is a male plug for mating, and the third communication connector is a female plug for mating. Through the mating of the male plug for mating and the female plug for mating, the communication connection between the main unit 100 and the oxygen mixing module 300 is realized.

[0054] In some embodiments, an oxygen concentration sensor is further provided at the first air inlet. Through the oxygen concentration sensor, the actual concentration of the oxygen flowing into the main unit 100 can be monitored, so as to be able to judge whether there are deviations and fluctuations between the theoretical oxygen inflow concentration and the actual oxygen inflow concentration, and be able to better autonomously control the output oxygen flow rate and concentration, thereby contributing to improving the treatment effect on the patient.

[0055] As Figure 8 shown, in some embodiments, a second baffle 520 is detachably connected to the main unit 100. A hose connector is provided on the second baffle 520, and the hose connector is communicated with the first air inlet hole 110 of the main unit 100. Through this hose connector, the first air inlet hole 110 can access external gas, supporting the diversity of the gas components of the main unit 100.

[0056] Refer to Figure 1 shown, an air inlet 150 is further provided on the main unit 100. Under the action of the fan in the main unit 100, air enters the main unit 100 and is mixed with oxygen. After the mixed gas is pressurized by the fan, it flows through the water tank 200 to humidify the mixed gas, and the humidified mixed gas enters the patient's body through the patient interface.

[0057] In some embodiments, the air inlet 150 is provided with a filter to remove dust, bacteria, viruses, and other fine particles from the air, ensuring that the air entering the main unit 100 and ultimately supplied to the patient is clean and safe. At the same time, the air inlet 150 also serves an auxiliary heat dissipation function by introducing cooler external air to help reduce the operating temperature of internal components, extend the service life of the device, and maintain stable operation.

[0058] Refer to Figure 4 As shown, in one of the embodiments, the respiratory physiotherapy device further includes a first baffle 510 detachably connected to the main unit 100. The first baffle 510 is provided with a first hole-blocking column 511, and the first hole-blocking column 511 can be inserted into the first air inlet hole 110 to block the first air inlet hole 110. The first baffle 510 can be used as a hole-blocking device. When oxygen input is not required, the first air inlet hole 110 is blocked by the first baffle 510; when oxygen input is required, the first baffle 510 is removed, and oxygen can be input through an oxygen supply device. By the detachable connection between the first baffle 510 and the main unit 100, the first baffle 510 can be conveniently installed or removed.

[0059] Refer to Figure 8 As shown, in one of the embodiments, a liquid injection hole 230 is provided at the top of the water tank 200. When the water consumption in the water tank 200 is relatively large, water can be injected into the water tank 200 through the liquid injection hole 230, so that the water tank 200 can provide a larger water flow rate, which is suitable for scenarios with a large humidification demand. In other embodiments, the liquid injection hole 230 may not be provided, which is suitable for scenarios with a small humidification demand.

[0060] Refer to Figures 1 to 3 As shown, the main unit 100 is provided with a first positioning portion 140, and the water tank 200 is provided with a first mating portion 240 for snap-fitting with the first positioning portion 140. In some embodiments, the first positioning portion 140 can be a protruding block, and the first mating portion 240 can be a groove adapted to the shape of the block. Through the snap-fitting of the block and the groove, the water tank 200 can be conveniently and quickly connected to the main unit 100. In other embodiments, the first positioning portion 140 can be a groove, and the first mating portion 240 can be a block. In other embodiments, the first positioning portion 140 and the first mating portion 240 can also adopt connection methods such as magnetic attraction connection, screw connection, and bonding.

[0061] Among them, the water tank 200 includes a box body and a box cover, and the first engaging portion 240 can be provided on the box cover. During use, the box body is filled with water, then the box body is directly placed above the main unit 100 of the ventilator, and finally the box cover is covered on the box body, and the first positioning portion 140 is connected and fixed to the first engaging portion 240. At this time, the box body will be fixed between the box cover and the main unit 100, thus completing the assembly operation of the water tank 200 and the main unit 100. In some embodiments, a viewing window is provided on the box cover. Through the viewing window, the user can conveniently directly observe the remaining water volume in the water tank 200. When the remaining water volume is small, water can be replenished through the liquid injection hole 230 or by opening the box cover to ensure humidification reliability and improve the user experience. Among them, the viewing window can be made of transparent glass or transparent plastic, with a simple structure, easy to manufacture, low cost, and good visibility.

[0062] In one embodiment, a heating element is provided inside the main unit 100, and a heat transfer element is provided at the bottom of the water tank 200. The heat transfer element is used to conduct the heat of the heating element to the water tank 200. Since the air directly inhaled from the outside or the gas after being processed by the fan is usually at a low temperature, the unheated cold air may irritate the respiratory tract, causing discomfort or even damage to the respiratory mucosa. The heating element is used to warm the gas delivered to the patient, for example, heating the gas to a temperature close to the human body temperature (about thirty-seven degrees Celsius) to ensure that the gas inhaled by the patient has an appropriate temperature and humidity. In a cold environment, the unheated gas may quickly cool down after entering the breathing circuit, resulting in the formation of condensed water inside the pipeline. These condensed waters will not only affect the gas transmission efficiency but also may cause bacterial growth and increase the risk of infection. The heating element can help maintain the temperature inside the pipeline and reduce the occurrence of condensation. At the same time, because the heat transfer element is provided at the bottom of the water tank 200, the heat of the heating element can be transferred to the water tank 200, causing the water in the water tank 200 to heat and evaporate to form water vapor, thereby forming humidified gas. In some embodiments, the heating element can be a heating wire or a heating plate.

[0063] In some embodiments, the second air outlet 220 of the water tank 200 is communicated with the patient interface through a pipeline. In one embodiment, the patient interface is a nasal cannula, and the pipeline and the patient interface are of an integral or split structure, and the pipeline is detachably connected to the water tank 200.

[0064] Refer to Figure 11As shown, in one embodiment, the respiratory physiotherapy device further includes an oxygen production module 600 detachably connected to the host 100, and the oxygen production module 600 can produce oxygen in the air and deliver oxygen to the host 100. Among them, a third assembly part 610 is provided on the oxygen production module 600, and the third assembly part 610 can be connected to the first air inlet 110. By integrating the oxygen production module 600, oxygen can be directly extracted from the air and immediately supplied to the patient without relying on an external oxygen source (such as an oxygen cylinder or a central oxygen supply system), thereby achieving instant oxygen supply; and it can ensure a continuous and stable oxygen supply, avoiding interruptions caused by replacing oxygen cylinders or other external oxygen supply equipment.

[0065] In some embodiments, the oxygen production module 600 includes a compressor, a molecular sieve tower, an oxygen storage tank, a pressure regulating valve and a proportional valve connected in sequence. The oxygen production module 600 is provided with an oxygen outlet connector connected to the proportional valve, and the oxygen outlet connector can be connected to the first air inlet of the host 100 or the oxygen connector of the oxygen mixing module 300. Specifically, the compressor draws air and compresses it and inputs it into the molecular sieve tower, and the molecular sieve tower extracts oxygen therein and then inputs it into the oxygen storage tank. The oxygen stored in the oxygen storage tank is input into the host 100 through the oxygen outlet connector after the pressure regulating effect of the pressure regulating valve and the flow regulating effect of the proportional valve.

[0066] The above-mentioned respiratory therapy equipment can directly extract oxygen from the air and immediately supply it to the patient through the oxygen production module 600, without relying on an external oxygen source (such as an oxygen cylinder or a central oxygen supply system), thereby achieving instant oxygen supply; and can ensure a continuous and stable oxygen supply to avoid interruptions caused by replacing oxygen cylinders or other external oxygen supply equipment. The oxygen mixing module 300 is detachably connected to the host 100, so that the oxygen mixing module 300 can deliver the oxygen of the oxygen production module 600 to the host 100 at different concentrations and flow rates. By adjusting the mixing ratio of air and oxygen, the patient can be provided with a corresponding oxygen concentration gas. For example, for patients with weak respiratory function and requiring high oxygen support, the oxygen content can be increased; for those with mild symptoms, the oxygen content can be reduced, so that the mixed gas is close to natural air, meeting diverse respiratory support needs and improving the targetedness and effectiveness of treatment. A fan is provided inside the host 100. The fan forms positive-pressure gas by compressing air, which is humidified by the water tank 200 and then transported to the human body through the pipeline and the mask, so that a certain positive pressure is maintained in the patient's respiratory tract when inhaling, helping the patient to open the collapsed airway, making it easier for air to enter the lungs, increasing alveolar ventilation, and preventing sleep syndromes such as sleep apnea and hypopnea, so as to assist the patient in breathing better.

[0067] The mixed gas coming out of the first air outlet 120 of the host 100 enters the water tank 200 through the second air inlet 210. Using the principle of heating and evaporation, the water in the water tank 200 forms water vapor and contacts the gas, realizing gas humidification, protecting the respiratory mucosa, and avoiding damage and inflammation caused by inhaling dry gas; preventing the secretion from drying and hardening, maintaining the patency of the respiratory tract, and reducing the risk of blockage; it can also improve the comfort of the user, reduce discomfort such as dry throat and cough, enhance the acceptance of the respiratory therapy device, and make the user more adaptable to the long-term use of the respiratory therapy device. By means of the titration module 400, the respiratory parameters of the patient such as respiratory rate, gas pressure, and gas flow are monitored, and the most suitable respiratory support intensity is accurately matched for the patient, which can not only ensure the patency of the airway and prevent problems such as apnea, but also avoid discomfort or injury caused by excessive pressure to the patient, help the patient find a better treatment pressure level, improve the sleep quality and treatment effect, and make the respiratory support more accurate, more comfortable, and more effective. This respiratory therapy device can flexibly select and combine different modules according to the specific needs of the patient to achieve a personalized treatment plan.
