[0003] Currently, there is an MRI ventilator on the market, which is expensive to manufacture, and its consumables are disposable and equally expensive. However, using a traditional resuscitation bag to deliver oxygen to the patient is limited by the length of the bag's tubing. The tubing length of a traditional resuscitation bag does not support long-distance oxygen delivery.
[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0032] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0033] This utility model provides, for example Figure 1 , Figure 2 The diagram illustrates a novel ventilation device for delivering oxygen and air to patients over long distances, facilitating MRI scans with a continuous oxygen supply. Its main components include: a ventilation tube 1, an oxygen mask 2, a pressure balloon 3, and an oxygen bag 4. The oxygen mask 2 is connected to one end of the ventilation tube 1 and is used to deliver oxygen to the patient. During use, the oxygen mask 2 is worn over the patient's mouth and nose for easy inhalation and exhalation. The pressure balloon 3 is connected to the other end of the ventilation tube 1. The pressure balloon 3 is an elastic balloon used to pump oxygen and air to the oxygen mask 2. The pressure balloon 3 has a hollow internal structure. During use, medical personnel squeeze the pressure balloon 3 at a certain frequency, pumping the air and oxygen inside the pressure balloon 3 to the oxygen mask 2. The oxygen bag 4 is connected to the tubing of the pressure balloon 3 and is used to store oxygen and supply oxygen to the pressure balloon 3.
[0034] The pressure balloon 3 is equipped with an air inlet valve 31, which is configured as a one-way air inlet valve. Because the pressure balloon 3 is an elastic balloon, it automatically inflates and returns to its original position after being pressed and released by medical personnel. During the inflation process, the air pressure inside the pressure balloon 3 is relatively low, so air is drawn into the cavity of the pressure balloon 3 through the air inlet valve 31. Simultaneously, oxygen from the oxygen bag 4 is also drawn into the cavity of the pressure balloon 3, mixing the air and oxygen. When the pressure balloon 3 returns to its original position, medical personnel can press it again to pump the air from the cavity to the oxygen mask 2, thus providing oxygen to the patient. It is understood that when the pressure balloon 3 is pressed, because the air inlet valve 31 is a one-way valve allowing air to enter the pressure balloon 3 from the outside, the air inside the pressure balloon 3 will not leak from the air inlet valve 31.
[0035] It should be noted that some patients with endotracheal intubation or tracheotomy require MRI scans. However, due to the strong magnetic field of MRI machines, conventional ventilators cannot be installed in the MRI examination room. Currently, there are MRI ventilators on the market, but these are expensive to manufacture, and their consumables are disposable and equally costly. Using traditional resuscitation bags to deliver oxygen to patients is limited by the length of the resuscitation bag tubing. The tubing length of traditional resuscitation bags does not support long-distance oxygen delivery.
[0036] The ventilation tube 1, oxygen mask 2, pressure bag 3, and oxygen bag 4 in this application are all made of non-metallic materials and will not affect the MRI examination. The ventilation tube 1 is configured with sufficient length, allowing medical staff to stand at a considerable distance and press the pressure bag 3 to deliver oxygen and air to the patient. This allows the patient to continue receiving oxygen during the MRI examination, making it more convenient for high-risk patients to undergo MRI scans.
[0037] Furthermore, such as Figure 1 As shown, a first one-way valve 05 is provided between the pressure balloon 3 and the ventilation tube 1. The first one-way valve 05 is open to the oxygen mask 2 in one direction. The pressure balloon 3 pumps oxygen and air to the oxygen mask 2 through the first one-way valve 05. When the pressure balloon 3 inflates and inhales, the first one-way valve 05 closes, and air cannot flow from the ventilation tube 1 into the cavity of the pressure balloon 3.
[0038] like Figure 2 As shown, a second one-way valve 5 is installed between the pressure balloon 3 and the oxygen bag 4, allowing one-way flow from the oxygen bag 4 to the pressure balloon 3. When the pressure balloon 3 is pressed to inflate, the second one-way valve 5 closes, preventing the air and oxygen in the cavity of the pressure balloon 3 from flowing back into the oxygen bag 4. This completes the air and oxygen pumping process.
[0039] Furthermore, such as Figure 1 , Figure 2 As shown, an oxygen humidifier 6 is installed between the oxygen bag 4 and the pressure balloon 3. The oxygen humidifier 6 is used to humidify the oxygen inside the oxygen bag 4. It should be noted that direct inhalation of dry oxygen may irritate the respiratory mucosa, causing discomfort or even damage. The oxygen humidifier 6 increases the humidity of the oxygen by converting water into a fine mist, allowing the oxygen to carry a certain amount of moisture as it passes through the humidifier, making it gentler and more comfortable, and reducing irritation to the respiratory tract. For patients with respiratory diseases who require long-term oxygen therapy, using the oxygen humidifier 6 can alleviate symptoms such as coughing and dry throat caused by dry oxygen. Some oxygen humidifiers 6 also have a filtration function, which can remove some impurities and dust from the oxygen, improving its purity and further protecting the patient's respiratory tract.
[0040] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, a sleeve 32 is provided at one end of the pressure balloon 3, and the pressure balloon 3 is connected to the oxygen bag 4 through the sleeve 32. The upper end of the oxygen humidification tank 6 is movably connected to the sleeve 32. The sleeve 32 is a rigid sleeve 32, which has sufficient structural strength to suspend and connect the oxygen humidification tank 6 and the oxygen bag 4.
[0041] It should be noted that the oxygen humidification cylinder 6 will shake when medical staff press the pressure balloon 3. To ensure that the liquid inside the oxygen humidification cylinder 6 can perform its humidification function normally and to prevent backflow, the upper end of the oxygen humidification cylinder 6 is movably connected to the sleeve 32. This allows the oxygen humidification cylinder 6 to form a pendulum structure, ensuring that the oxygen humidification cylinder 6 always hangs downwards and that the liquid remains in the lower half of the oxygen humidification cylinder 6.
[0042] Furthermore, such as Figure 3 As shown, the upper end of the oxygen humidification tank 6 is provided with an air inlet port 61 and an air outlet port 62. The end of the air inlet port 61 and the air outlet port 62 away from the oxygen humidification tank 6 is provided with a movable sleeve 63. The oxygen humidification tank 6 is sleeved on the side wall of the sleeve 32 through the movable sleeve 63. In this embodiment, the air inlet port 61 and the air outlet port 62 of the oxygen humidification tank 6 are integrally formed with the movable sleeve 63.
[0043] The air inlet port 61 and the air outlet port 62 are respectively connected to the air inlet end and the air outlet end pipe of the sleeve 32.
[0044] The oxygen humidification tank 6 has a hollow tank structure. Specifically, the oxygen humidification tank 6 includes a tank body and a top cover, with the air inlet port 61 and the air outlet port 62 both integrally formed with the top cover. When it is necessary to replace or replenish the liquid in the oxygen humidification tank 6, the top cover and the tank body can be separated.
[0045] Furthermore, such as Figure 1 As shown, a pressure relief valve 11 is installed on the first one-way valve 05. The pressure relief valve 11 is used to release the high-pressure air in the ventilation tube 1. It is understandable that when medical personnel press the pressure balloon 3 too quickly, the air pressure inside the ventilation tube 1 will increase. When the air pressure inside the ventilation tube 1 becomes too high, the pressure relief valve 11 can release the high-pressure air inside the ventilation tube 1 to avoid affecting the patient's breathing.
[0046] Furthermore, such as Figure 1 As shown, an exhalation valve 12 is installed on the ventilation tube 1. The exhalation valve 12 is used to expel the patient's exhaled air. The exhalation valve is located on the section of the ventilation tube 1 near the oxygen mask 2 to ensure that the patient's exhaled air is expelled as quickly as possible.
[0047] Furthermore, such as Figure 1 As shown, an oxygen tube 13 is connected to the ventilation tube 1. The oxygen tube 13 is used to connect to an external oxygen supply and deliver oxygen to the ventilation tube 1. The oxygen delivered by the oxygen tube 13 mixes with the air pumped in by the pressure balloon 3, forming a sufficient airflow of oxygenated air to supply the patient's breathing.
[0048] It should be noted that the oxygen tube 13 on ventilation tube 1 can provide additional oxygen to ventilation tube 1. The length of oxygen tube 13 needs to be configured to be long enough to keep the oxygen supply end away from the nuclear magnetic resonance device.
[0049] Furthermore, such as Figure 1 , Figure 2 As shown, a gas storage valve 41 is installed on the section of the sleeve 32 between the air inlet port 61 and the oxygen bag 4. The gas storage valve 41 is connected to the oxygen bag 4 and is configured as a one-way air inlet valve 31. The gas storage valve 41 is used to supply fresh oxygen to the oxygen bag 4. Before using this device, the oxygen bag 4 needs to be replenished with sufficient oxygen through the gas storage valve 41.
[0050] Furthermore, the ventilation tube 1 is a flexible ventilation tube 1. Understandably, the flexible ventilation tube 1 has good flexibility, which facilitates oxygen supply operations by medical staff.
[0051] In summary, this application provides a novel ventilation device. In this invention, medical personnel can press the pressure balloon 3, which pumps air and oxygen from the oxygen bag 4 into the oxygen mask 2. This allows patients to continue receiving oxygen during MRI scans, making MRI scans more convenient for high-risk patients.
[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
