Description

Technical Field

[0001] The utility model belongs to the technical field of medical oxygen bags, and particularly relates to a continuous pressurized oxygen bag supply device. Background Art

[0002] CT (Computed Tomography) and Magnetic Resonance Imaging (MRI) are one of the commonly used examinations for clinical disease diagnosis. At the same time, medical oxygen bags are commonly used oxygen containers in clinical practice and are often used in patient examinations, transfers or emergency treatment. Especially when used in the examination room, the precisely collimated X-ray beams, gamma rays, ultrasound waves, etc. used in CT examinations have certain radiation to the human body, and the MRI examination room has a strong magnetic field. All metal objects are absolutely prohibited from being brought in, especially metal oxygen cylinders. Therefore, in order to minimize the unnecessary radiation received by the accompanying family members during CT examinations and the necessary oxygen supply during MRI examinations, the use of oxygen bags is particularly necessary and convenient. Since the oxygen inside the oxygen bag is stored in a certain gaseous pressure form, as the amount of oxygen decreases during use, the pressure inside the oxygen bag also gradually decreases, resulting in its output pressure gradually weakening and failing to meet the oxygen supply demand. At this time, it is necessary to press the oxygen bag manually and apply external force to the oxygen bag to ensure that the oxygen bag maintains normal pressure output to avoid affecting the patient's oxygen supply. However, this operation is cumbersome and the oxygen supply effect is poor. It is difficult to stably control the output pressure of the oxygen bag by manpower. If a new oxygen bag is replaced during the process, the patient's oxygen supply may be disconnected, which may affect treatment and even endanger life.

[0003] Therefore, a device for continuously pressurizing and supplying oxygen bags is needed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Next, the embodiments are described in detail to enable those skilled in the art to better understand the present invention:

[0025] An oxygen bag continuous pressurized supply device, such as Figures 1 to 5As shown, it includes an air bag 1 and an oxygen bag 2 2, one end of the oxygen bag 1 is provided with an output sub-tube 1 3, the output sub-tube 1 3 is connected with a hose 1 4, one end of the hose 4 is connected to a confluence pipe 1 5, one end of the confluence pipe 5 is connected to one end of a main output pipe 6, one end of the oxygen bag 2 is provided with an output sub-tube 2 7, the output sub-tube 2 7 is connected with a hose 2 8, one end of the hose 2 8 is connected to a confluence pipe 2 9, one end of the confluence pipe 2 9 is connected to the other end of the main output pipe 6, and a switch knob 10 is provided inside the main output pipe 6, a center column 11 is provided on the switch knob 10, and a blocking piece 12 is provided on the center column 11. By using the oxygen bag 1 and the oxygen bag 2 2 alternately, when one of the oxygen bag 1 or the oxygen bag 2 2 is used up, the other one is supplemented with oxygen at the same time, so as to achieve stable oxygen output, and the oxygen bag 1 and the oxygen bag 2 2 are used in combination, the oxygen supply amount and oxygen supply time to the patient can be increased, thereby helping to increase the treatment time of the patient.

[0026] The switch knob 10 is rotatably installed inside the main output tube 6, and the output sub-tube 1 3, the output sub-tube 2 7 and the main output tube 6 are all connected to each other. By rotating and twisting the switch knob 10, the blocking piece 12 is also rotated, thereby respectively realizing the connection between the manifold 1 5 and the main output tube 6 or the manifold 2 9 and the main output tube 6, ensuring that the oxygen in the oxygen bag 1 1 or the oxygen bag 2 2 can be output.

[0027] There are two plugging pieces 12, which form a 90-degree angle with each other and are vertically installed on the center column 11. When the manifold 1 5 needs to be connected to the main output pipe 6, one of the plugging pieces 12 on the center column 11 blocks the manifold 2 9 by rotating the switch knob 10, and the other plugging piece 12 rotates to the rear of the main output pipe 6 for blocking; when the manifold 2 9 needs to be connected to the main output pipe 6, one of the plugging pieces 12 on the center column 11 blocks the manifold 1 5 by rotating the switch knob 10, and the other plugging piece 12 rotates to the rear of the main output pipe 6 for blocking. Further, setting the front ends of the two plugging pieces 12 to be arc-shaped is conducive to improving the good blocking of the manifold 1 5 and the manifold 2 9, and ensuring their effective sealing performance.

[0028] A pushing chamber 13 is provided inside the central column 11, a sliding rod 14 is provided at one end of the blocking piece 12, the sliding rod 14 and the blocking piece 12 are slidably installed in the pushing chamber 13, a compression spring 15 is connected to the bottom of the sliding rod 14, a sliding chamber 16 is provided below the pushing chamber 13, the pushing chamber 13 and the sliding chamber 16 are connected to each other, a channel 17 is provided on the side wall of one common end of the pushing chamber 13 and the sliding chamber 16, a base block 18 is slidably installed below the sliding chamber 16, the bottom of the base block 18 is fixedly installed on the bottom of the main output pipe 6, and a channel 2 19 is provided inside one end of the base block 18.

[0029] When the sliding chamber 16 and the base block 18 slide apart from each other, the channel 1 17 and the channel 2 19 are disconnected from each other; when the sliding chamber 16 and the base block 18 slide together, the channel 1 17 and the channel 2 19 are connected to each other. Further, the channel 2 19 is set to a U-shaped structure. When the channel 1 17 and the channel 2 19 are disconnected from each other, oxygen cannot enter the push chamber 13. Therefore, the oxygen passes through the bottom of the channel 2 19 and then flows out from the top of the channel 2 19, forming a local circulation discharge.

[0030] Furthermore, a spherical spring block 20 is provided at the other end of the base block 18, and a spherical groove 21 that is engaged with the spherical spring block 20 is opened on the side wall of the other end of the sliding chamber 16. When the switch knob 10 is pressed, the spherical spring block 20 is engaged with the spherical groove 21 to ensure the stability of the engaged state. When releasing, the spherical spring block 20 can be disengaged from the spherical groove 21 by pulling it out upward with force.

[0031] Working principle: Figure 2 and Figure 3 , Figure 4 and Figure 5 As shown, when in use, firstly, by rotating the switch knob 10, the manifold 1 5 is connected to the main output pipe 6 or the manifold 2 9 is connected to the main output pipe 6, so that the oxygen in either the oxygen bag 1 or the oxygen bag 2 2 can be output, and the switch knob 10 is pressed while rotating the switch knob 10, so that the channel 1 17 and the channel 2 19 are connected to each other, and then the spherical spring clamping block 20 is clamped into the spherical clamping groove 21 to ensure the stability of the conductive state of the channel 17 and the channel 2 19. At this time, one of the bags, such as the oxygen bag 1, is turned on for output. Due to its high output pressure, part of the oxygen in the oxygen bag 1 enters the channel 17 from the channel 2 19, and the oxygen entering the channel 17 immediately enters the pushing chamber 13, exerting downward pressure on the sliding rod 14, so that the sliding rod 14 drives the blocking piece 12 to move downward together, and then the blocking piece 12 blocks the manifold 2 9 to prevent the oxygen in the oxygen bag 2 2 from being output.

[0032] When the oxygen in the oxygen bag 1 is used up, the output pressure is also reduced due to the decrease in the oxygen content in the oxygen bag 1, so that the oxygen in the push chamber 13 is insufficient to keep the blocking piece 12 in the blocked state, and the sliding rod 14 begins to move upward with the reaction of the compression spring 15, so that the blocking piece 12 cannot block the manifold 2 9. At this time, the manifold 2 9 is opened, so that the oxygen in the oxygen bag 2 is output to the main output pipe 6, so as to realize the automatic output switching of the oxygen bag 1 and the oxygen bag 2, and to ensure the stable oxygen output pressure as much as possible, thereby ensuring the oxygen supply and oxygen supply time for the patient, improving the treatment time for the patient, avoiding the existing unstable pressure output that needs manpower to maintain, not only improving work efficiency but also reducing human labor. When the oxygen bag 1 or the oxygen bag 2 is used up, it only needs to be supplemented with air externally for the next cycle, so as to facilitate the oxygen supply work for the patient next time.
