[0002] Oxygen bags are bags used to hold oxygen. They are mainly made of non-toxic and non-toxic chemical materials. The biggest and most significant features of medical oxygen bags are their light weight, portability, and ease of storage. They are widely used in pre-hospital emergency care, patient transport, and primary healthcare institutions. They can be used for home healthcare, as well as for patient transport and pre-hospital emergency care in medical units. When using oxygen bags, a regulator is usually used to adjust the outflow rate of the gas.
[0003] For example, publication number CN217612350U proposes a medical oxygen bag oxygen supply flow control device, including a tube body, a guide cylinder horizontally installed on one side of the tube body, a regulating valve provided in the guide cylinder, a valve seat horizontally connected to the regulating valve on the inner wall of the tube body, a filter provided at the top of the tube body, and a heater provided at the bottom of the tube body. However, this utility model does not have the effect of limiting the regulating screw during use. The regulating screw is exposed and can easily rotate when accidentally touched, causing the oxygen bag flow regulation to change.
[0004] Therefore, to solve the above problems, an oxygen bag flow regulating device is proposed. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an oxygen bag flow regulating device that has advantages such as reducing accidental activation. It solves the problem that the regulating screw is exposed and can easily rotate when accidentally touched, causing changes in the oxygen bag flow regulation.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an oxygen bag flow regulating device, comprising an oxygen bag body and an regulating mechanism, wherein a connecting pipe is provided on the oxygen bag body, and a connecting sleeve is provided at one end of the connecting pipe;
[0007] The regulating mechanism includes an oxygen delivery pipe, on which a flow meter and a valve body are installed. An adjusting rod is rotatably installed inside the valve body. A connecting frame is installed on the upper end face of the valve body. A ball valve core is installed at one end of the adjusting rod. The regulating mechanism also includes a limiting component.
[0008] The limiting component includes a knob, two connecting plates on the outer side of the knob, a movable rod on the lower end face of the connecting plate, a support plate rotatably mounted inside the connecting frame, two connecting cylinders on the upper end face of the support plate, a spring inside the connecting cylinder, multiple limiting strips on the outer side of the adjusting rod, and multiple connecting grooves inside the knob that are adapted to the width of the limiting strips.
[0009] Furthermore, the support plate has a connection hole inside that matches the width of the adjusting rod, and the ball valve core is located inside the valve body.
[0010] Furthermore, the plurality of limiting strips are equidistantly distributed, and the positions of the limiting strips correspond to those of the connecting grooves.
[0011] Furthermore, one end of the spring is fixedly connected to one side of the movable rod, and one end of the adjusting rod passes through the valve body and extends to the inside of the connecting frame.
[0012] Furthermore, the inner wall of the connecting frame is provided with an annular groove, and the outer side of the support plate is provided with two sliders that are movably arranged with the annular groove.
[0013] Furthermore, the outer surface of the connecting sleeve is threaded, and both ends of the oxygen delivery pipe are provided with threaded grooves that are threadedly connected to the connecting sleeve.
[0014] Furthermore, the movable rod is located inside the connecting cylinder, and the connecting cylinder has a movable hole that matches the size of the movable rod.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. This oxygen bag flow rate regulating device, by setting an regulating mechanism, allows the oxygen bag to be used to transport oxygen. When the oxygen bag is in use, pressing down on the knob connects the connecting groove on the knob to the limiting strip on the outside of the regulating rod. Then, rotating the knob drives the ball valve core connected to the regulating rod to rotate, thereby achieving the effect of regulating the oxygen flow rate. This reduces the possibility of changes in the oxygen bag flow rate regulation due to accidental contact with the knob during the use of the oxygen bag.
[0017] 2. This oxygen bag flow rate regulating device can display the flow rate of oxygen delivered by the oxygen bag through the flow meter setting, and can adjust the flow rate of oxygen delivered by the oxygen bag through the regulating mechanism, which is convenient for users.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 In this embodiment, the oxygen bag body 1 and the adjustment mechanism are provided. The oxygen bag body 1 is provided with a connecting pipe 2, and a connecting sleeve 3 is provided at one end of the connecting pipe 2. The outer surface of the connecting sleeve 3 is threaded. Both ends of the oxygen delivery pipe 4 are provided with threaded grooves that are threadedly connected to the connecting sleeve 3.
[0026] Please see Figure 1-2 The regulating mechanism includes an oxygen delivery pipe 4, a flow meter 5 and a valve body 6 are installed on the oxygen delivery pipe 4, an adjusting rod 9 is rotatably installed inside the valve body 6, a connecting frame 7 is installed on the upper end face of the valve body 6, a ball valve core 10 is installed at one end of the adjusting rod 9, and the regulating mechanism also includes a limiting component.
[0027] It should be noted that when oxygen bag 1 is used to deliver oxygen, one end of oxygen delivery tube 4 is connected to the connecting sleeve 3 set on the connecting tube 2. This allows the flow rate of oxygen delivered by oxygen bag 1 to be displayed by the flow meter 5, thereby accurately calculating the actual amount of oxygen inhaled by the patient. Furthermore, the flow rate of oxygen delivered by oxygen bag 1 can be adjusted by the adjustment mechanism, making it convenient for the user.
[0028] Please see Figure 1-5The limiting component includes a knob 8, two connecting plates 12 are provided on the outer side of the knob 8, a movable rod 14 is provided on the lower end face of the connecting plate 12, a support plate 11 is rotatably provided inside the connecting frame 7, two connecting cylinders 13 are provided on the upper end face of the support plate 11, a spring 16 is provided inside the connecting cylinder 13, the movable rod 14 is located inside the connecting cylinder 13, and an movable hole adapted to the size of the movable rod 14 is opened inside the connecting cylinder 13.
[0029] The adjusting rod 9 has multiple limiting strips 15 on its outer side, and the knob 8 has multiple connecting grooves 17 that are adapted to the width of the limiting strips 15 inside. In actual use, the multiple limiting strips 15 are distributed at equal intervals, and the positions of the limiting strips 15 and the connecting grooves 17 correspond to each other. The support plate 11 has connecting holes that are adapted to the width of the adjusting rod 9 inside.
[0030] In actual use, the knob 8 is connected to the limiting strip 15 on the outside of the adjusting rod 9 through the connecting groove 17 inside it, so that the knob 8 and the adjusting rod 9 are engaged and connected, so that when the knob 8 is turned, the adjusting rod 9 rotates accordingly, thereby achieving the effect of adjusting the oxygen flow of the oxygen bag 1.
[0031] Please see Figure 2-3 One end of the spring 16 is fixedly connected to one side of the movable rod 14. One end of the adjusting rod 9 passes through the valve body 6 and extends to the inside of the connecting frame 7. The ball valve core 10 is located inside the valve body 6. An annular groove is provided on the inner wall of the connecting frame 7. Two sliders are provided on the outer side of the support plate 11 and are movably arranged with the annular groove. The support plate 11 can rotate in the annular groove opened on the connecting frame 7 by the sliders.
[0032] In actual use, when the knob 8 is pressed, the knob 8 slides in the connecting cylinder 13 through the movable rod 14 connected to the connecting plate 12. The movable rod 14 squeezes the spring 16. After the knob 8 is released, the spring force of the spring 16 can drive the knob 8 to reset, so that the knob 8 is separated from the adjusting rod 9. This ensures that when the knob 8 is accidentally touched and rotated, the adjusting rod 9 will not be rotated with it, thus ensuring the stability of the oxygen bag 1 when delivering oxygen and reducing the possibility of changes in the flow rate regulation of the oxygen bag 1 due to accidental touching of the knob 8 during the use of the oxygen bag 1.
[0033] The working principle of the above embodiments is as follows:
[0034] When oxygen bag 1 is used to deliver oxygen, one end of oxygen delivery tube 4 is connected to the connecting sleeve 3 on connecting tube 2. By pressing down on knob 8, knob 8 slides in connecting cylinder 13 via movable rod 14 connected to connecting plate 12. During the pressing of knob 8, it is simultaneously driven to rotate. Knob 8 can rotate in the annular groove inside connecting frame 7 via slider on support plate 11, rotating the connecting groove 17 on knob 8 to an angle corresponding to the position of limiting strip 15 on the outside of adjusting rod 9, so that knob 8 is connected to adjusting rod 9. Then, turn knob 8 to rotate the ball valve core 10 connected to one end of the adjusting rod 9, thereby adjusting the oxygen flow rate of the oxygen bag 1. After adjustment, release knob 8, and the spring force of spring 16 will cause knob 8 to reset, separating knob 8 from adjusting rod 9. This ensures that if knob 8 is accidentally touched and rotated, the adjusting rod 9 will not be rotated, thus ensuring the stability of oxygen bag 1 when delivering oxygen and reducing the possibility of changes in oxygen bag 1 flow rate adjustment due to accidental touch of knob 8 during use.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
