Description

Technical Field

[0001] The present invention relates to an assisted breathing management device. Background Art

[0002] Respiratory motion has always been one of the problems that need to be overcome during thoracic and abdominal radiotherapy. Various respiratory motion management measures are required to achieve accurate radiotherapy. One solution is to take a deep breath and hold your breath multiple times. For example, in radiotherapy for left-sided breast cancer, the deep breath-holding approach can improve the stability of the target area and reduce the dose of OARs such as the heart and lungs. Moreover, compared with free-breathing-based respiratory gating therapy, it can further save treatment time and improve efficiency. This is of great significance to some busy treatment centers.

[0003] However, based on the current popular treatment technology, whether it is IMRT or VMART, a complete DIBH (Deep Inspiration Breath Holding) radiotherapy still takes 3-5 minutes. During this period, the patient needs to repeat DIBH several times, each lasting about 20 seconds. Studies have shown that frequent breath holding can cause problems such as stress and body position changes in patients, which is particularly important during proton therapy. Therefore, how to effectively prolong the duration of a single deep inspiration breath holding is a very valuable study. Summary of the invention

DETAILED DESCRIPTION

[0059] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] like Figure 1-2The figure shows an auxiliary breathing management device of the present application, comprising: a high-flow one-way oral and nasal mask for a user to wear and a breathing control device for supplying oxygen to the user.

[0062] Among them, the first air inlet 20 is arranged on the shell 10 to be connected to the breathing control device. The first air outlet 30 is arranged on the shell 10 to be connected to the user's nasal cavity. The second air inlet 50 is arranged on the shell 10 to be connected to the user's oral cavity. The second air outlet 40 is arranged on the shell 10 to be connected to the external environment. The air inlet channel 60 is formed between the first air inlet 20 and the first air outlet 30. The air outlet channel 70 is formed between the second air outlet 40 and the second air inlet 50. The first one-way valve 80 is arranged in the air inlet channel 60 and is in a normally open state.

The linkage pin 100 is connected to the first one-way valve 80 and the second one-way valve 90 so that the two keep moving synchronously. When the first one-way valve 80 is switched to a fully closed state, the second one-way valve 90 is in a fully open state, and when the first one-way valve 80 is switched to a fully open state, the second one-way valve 90 is in a fully closed state. Under normal conditions, the high-flow unidirectional oronasal mask is bidirectionally connected. When the flow rate of the airflow flowing into the first air inlet 20 of the high-flow unidirectional oronasal mask is high, the bidirectional connection is switched to unidirectional connection. Based on the above structure, the breathing control device of the present application can be switched in multiple oxygen supply modes. A detailed description will be given later.

Figure 2 As for the position in the mouth, the specific position depends on the specific structure of the unidirectional high-flow oral and nasal mask.

[0065] As a preferred embodiment, the breathing control device includes: an air compressor, a heating gas tank, a flow valve, a humidifier, a sensor, a piston cylinder and a control unit. Among them, the air compressor is used to provide pressure. The heating gas tank is connected to the air compressor. The flow valve is connected to the heating gas tank. One end of the humidifier is connected to the flow valve and the other end is connected to the first air inlet 20. Preferably, the humidifier can be a disposable plug-in humidification filter element, which can be quickly replaced and can prevent cross infection. The sensor is arranged on the channel between the humidifier and the first air inlet 20 to detect the temperature, flow and pressure of the air flow passing through. One end of the piston cylinder is connected to the heating gas tank and the other end is connected to the flow valve. The control unit is electrically connected to the air compressor, the heating gas tank, the flow valve, the humidifier, the sensor and the piston cylinder to control the above components. In the present application, the heating gas tank is 20L and the piston cylinder is 5L. It can be understood that the size of the heating gas tank and the piston cylinder can be selected according to actual needs.

[0066] As a preferred embodiment, the breathing control device further comprises: an air-oxygen mixer, a filter and an oxygen concentration sensor.

[0067] The air-oxygen mixer inhales air and oxygen and mixes the two, and is electrically connected to the control unit. One end of the filter is connected to the air-oxygen mixer and the other end is connected to the air compressor. The filter is used to filter the mixed oxygen. The oxygen concentration sensor is arranged on the channel between the air-oxygen mixer and the filter to detect the oxygen content of the air flow passing through, and is electrically connected to the control unit.

[0068] As a preferred embodiment, the breathing control device further includes: an onboard touch display control unit and a remote touch display control unit.

[0069] The onboard touch display control unit is used for the user to operate the breathing control device, and is electrically connected to the central control unit. The remote touch display control unit is used for the user to remotely operate the breathing control device, and is communicatively connected to the central control unit.

[0070] In this application, the breathing control device has the following oxygen supply modes:

[0071] The first mechanical assisted ventilation mode. In the first mechanical assisted ventilation mode, the flow valve is opened, the airflow enters the humidifier from the heated air tank, the airflow at the first flow rate enters the user's nasal cavity through the air inlet channel 60, the first one-way valve 80 and the second one-way valve 90 are both opened, the user is trained to take deep inhalations and breathe freely, and the user's breathing cycle and the air delivery volume of each cycle are calculated.

[0072] The second mechanical assisted ventilation mode, in the second mechanical assisted ventilation mode, the flow valve is closed, the airflow is supplied from the piston cylinder to the humidifier according to the calculated air delivery volume, the airflow of the second flow rate enters the user's nasal cavity through the air inlet channel 60, the first one-way valve 80 is opened, and the second one-way valve 90 is closed, to assist the user to perform deep breathing and free breathing pre-oxygenation, and the second flow rate is greater than the first flow rate. In this mode, the piston cylinder quickly delivers a predetermined amount of gas into the user's nasal cavity at one time. And in order to prevent the airflow from overflowing from the user's mouth, at this time, the second one-way valve 90 is in a closed state. When the one-time rapid air supply is completed, the second one-way valve 90 returns to an open state, and the user can exhale the gas.

[0073] Asphyxiation oxygenation mode: In asphyxiation oxygenation mode, the flow valve is opened, the airflow enters the humidifier from the heated gas tank, and the airflow at the third flow rate enters the user's nasal cavity through the air inlet channel 60. The first one-way valve 80 and the second one-way valve 90 are both open, and the third flow rate is less than the second flow rate. At this time, high-flow oxygen enters through the nasal cavity and is exhaled from the mouth. In this process, oxygen in the nasopharynx is passively delivered to the lungs through the oxygenation pressure difference in the alveoli, allowing the user to achieve a breath-holding time of more than 5 minutes. When the user releases the breath-holding state, the mode is switched to mechanical assisted ventilation mode through remote control to help the user speed up the recovery of free breathing.

[0074] Specifically, the user adjusts the oxygen supply mode of the breathing control device through the onboard touch display control unit or the remote touch display control unit.

[0075] As a preferred embodiment, the second flow rate is greater than or equal to 80 L / min, and the first flow rate and the third flow rate are less than 80 L / min. That is, the speed of the airflow entering from the air inlet is greater than or equal to 80 L / min, and the airflow overcomes the elastic force of the first spring 85 and the second spring 95, so that the first one-way valve 80 is opened and the second one-way valve 90 is closed.

[0076] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
