Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model discloses a respiratory assistance training device for critically ill patients, including a transparent sleeve 1, an upper cover 3 fixed to the upper end of the transparent sleeve 1, and a base 2 fixed to the lower end of the transparent sleeve 1. It further includes: a hollow tube 5, the hollow tube 5 is installed inside the transparent sleeve 1, which can greatly reduce the volume of the device. Preferably, the transparent sleeve 1 is a component made of transparent acrylic board material, and a piston 15 adapted to the transparent sleeve 1 is slidably installed on the outer periphery of the hollow tube 5. By the up and down movement of the piston 15, the lower space inside the transparent sleeve 1 can cooperate with the breathing rhythm of the user. A first spring 16 is installed between the piston 15 and the upper cover 3 on the outer side of the hollow tube 5. On the one hand, it increases the resistance when the piston 15 moves upward inside the transparent sleeve 1, improving the breathing training effect of the patient. On the other hand, after the exhaust tube 11 is opened, it drives the piston 15 to move downward, and then facilitates the reset of the piston 15, which is beneficial to the training of the next breathing cycle. And a second one-way valve 17 is installed near the lower end inside the hollow tube 5. The second one-way valve 17 allows air to be input from the upper end to the lower end of the hollow tube 5, and then it can prevent the exhaled gas from being discharged from the hollow tube 5 when the patient exhales, thus avoiding air leakage;

[0023] Continue to refer to Figures 1-3 The above-mentioned respiratory assistance training device for critically ill patients further includes an exhalation tube 8. One end of the exhalation tube 8 is equipped with a face mask 9, and the face mask 9 is preferably a component made of silica gel. The other end of the exhalation tube 8 is connected to the base 2. A first one-way valve 14 is installed at the connection between the exhalation tube 8 and the base 2. Through the setting of the first one-way valve 14, it is possible to prevent the exhaled gas inside the transparent sleeve 1 from flowing back, causing discomfort to the patient. The lower end of the hollow tube 5 penetrates through the base 2 and is equipped with an inhalation tube 10. The other end of the inhalation tube 10 is connected to the middle section of the exhalation tube 8. By directly connecting the hollow tube 5 to the inhalation tube 10, when the patient inhales, air can directly enter the inside of the face mask 9 through the hollow tube 5 and the inhalation tube 10, thereby providing oxygen for the patient;

[0024] As Figure 2 and Figure 4 shown, an exhaust pipe 11 is installed at the bottom of the base 2, which is beneficial to the discharge of the exhaled gas inside the transparent sleeve 1. In order to facilitate the control of the exhaled gas inside the transparent sleeve 1, an exhaust assembly is provided at the other end of the exhaust pipe 11 for discharging the exhaled gas inside the transparent sleeve 1.

[0025] As Figure 4 and Figure 5 shown, the above-mentioned exhaust assembly includes an insertion tube 13 connected to the other end of the exhaust pipe 11. Preferably, the insertion tube 13 is a component made of stainless steel. A plugging sleeve 12 is slidably connected to the insertion tube 13. One end inside the plugging sleeve 12 is fixed with a rubber plug 19 adapted to the insertion tube 13. Preferably, the rubber plug 19 has a frustum structure, and the small circular surface is close to the insertion tube 13. Exhaust holes are evenly arranged along the axial direction on the outside of the plugging sleeve 12, which is beneficial to the output of the exhaled gas from the inside of the plugging sleeve 12. A handle is fixed on the outside of the plugging sleeve 12. By driving the plugging sleeve 12 to slide on the insertion tube 13 through the handle, the rubber plug 19 can be separated from and combined with the insertion tube 13, thereby controlling the opening and closing of the port of the insertion tube 13.

[0026] As Figure 5 shown, an installation ring is fixed inside the exhaust pipe 11, and a second spring 20 is installed between the installation ring and the rubber plug 19. Under the action of the second spring 20, the rubber plug 19 is maintained to block the insertion tube 13 to facilitate the blocking of the exhaust pipe 11.

[0027] As Figure 5 shown, sliding rails are symmetrically arranged on the outside of the insertion tube 13, and guide blocks slidingly connected to the sliding rails are provided on the inner wall of the plugging sleeve 12. Under the sliding connection between the guide blocks and the sliding rails, it is beneficial to pull the plugging sleeve 12 to slide on the insertion tube 13.

[0028] As Figure 1As shown, in order to facilitate the upward movement of the piston 15 inside the transparent sleeve 1, through holes 7 are evenly arranged on the upper surface of the upper cover 3 to maintain the stability of the air pressure above the piston 15 inside the transparent sleeve 1.

[0029] As Figure 3 shown, in order to improve the quality of the gas inhaled by the patient and prevent particulate impurities such as dust in the air from being inhaled into the patient's lungs, a filter 6 is installed through the upper cover 3 at the upper end of the hollow tube 5, and a filter element 18 is fixed below the filter 6 inside the hollow tube 5.

[0030] As Figure 1 shown, scale lines 4 are axially arranged on the outer side of the transparent sleeve 1 for reading the height of the piston 15 inside the transparent sleeve 1, so as to monitor the patient's exhaled volume.

[0031] The working principle and usage process of the present utility model: When in use, the mask 9 is placed over the patient's mouth and nose. When the patient exhales, the first one-way valve 14 opens, enabling the exhaled gas to be input into the interior of the transparent sleeve 1 through the exhalation tube 8. At this time, under the air pressure of the exhaled gas, the piston 15 moves upward inside the transparent sleeve 1. With the setting of the first spring 16, the resistance when the piston 15 moves upward is increased, thereby improving the training effect. Through the setting of the scale lines 4, the height of the piston 15 inside the transparent sleeve 1 is read to monitor the patient's exhaled volume. Push the handle to make the plugging sleeve 12 slide on the intubation tube 13, further making the rubber plug 19 move away from the intubation tube 13, so that the intubation tube 13 is in an open state. Subsequently, it is beneficial for the exhaled gas inside the transparent sleeve 1 to be discharged from the exhaust pipe 11. Release the handle, and under the elastic force of the second spring 20, the plugging sleeve 12 slides towards the intubation tube 13, and then the further plugging of the port of the intubation tube 13 can be achieved, so that the interior of the transparent sleeve 1 is in a relatively sealed state. During this process, the elastic force of the first spring 16 acts on the piston 15, thereby pushing the piston 15 downward to facilitate the reset of the piston 15 for the training of the patient's next breathing cycle. When the patient inhales, air directly enters the interior of the mask 9 through the hollow tube 5 and the inhalation tube 10, thus providing oxygen for the patient.
