Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology and relates to an oxygen bag pressurization device. Background Technology

[0002] Oxygen bags are widely used emergency oxygen supply devices in first aid scenarios or patient transport, favored for their portability. During use, the oxygen bag releases oxygen through its internal pressure. Initially, the bag is well-filled with gas, resulting in a high oxygen flow rate. However, as oxygen is gradually consumed, the internal pressure decreases, leading to a reduction in the oxygen flow rate, and sometimes even difficulty in expelling oxygen. To address this, medical staff typically need to manually press the oxygen bag to increase the flow rate. This manual operation not only increases the workload of medical staff but may also require a dedicated person to squeeze the oxygen bag, especially in emergency departments where the workload is already high; this manual method further reduces work efficiency.

[0003] In view of the above problems, there is an urgent need to develop a new type of oxygen bag for emergency departments that can automatically maintain a stable oxygen flow without manual pressing, thereby reducing the workload of medical staff and improving the efficiency of emergency departments.

Detailed Implementation

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] Example 1

[0031] This embodiment provides an oxygen bag pressurization device, such as... Figure 1 and Figure 2As shown, the device includes a bottom unit 1, a pressure-applying unit 2, and a telescopic unit 3. The bottom unit 1 includes an annular frame 11 made of medical-grade plastic. The pressure-applying unit 2 includes an annular pressure-applying element 21, which is a non-elastic element. Optionally, the pressure-applying element 21 may be made of medical-grade plastic, medical canvas straps, or other medical non-elastic materials. The telescopic unit 3 includes multiple straps 31 and a telescopic element 32. The straps 31 are made of a non-elastic material. Optionally, the straps 31 may be made of the same material as the pressure-applying element 21. One end of the straps 31 is fixedly connected to the pressure-applying element 21, and the other end is connected to the telescopic element 32. The frame 11 and the pressure-applying element 21 are arranged opposite to each other, so that the oxygen bag 5 can be placed between the multiple straps 31, with two diagonal points located within the frame 11 and the pressure-applying element 21, respectively. The telescopic element 32 is fixed to the frame 11 and applies pressure to the oxygen bag by pulling the straps 31.

[0032] Preferred, such as Figure 3 As shown, the telescopic component 32 includes a spring, and a fixed shaft 111 is provided on the frame 11. The spring is wound around the fixed shaft 111, and its two ends are fixedly connected to the fixed shaft 111 and the strap 31, respectively. When the oxygen bag pressurization device of this embodiment is not in use, due to the elastic contraction force of the spring, the strap 31 is wound around the outer periphery of the spring, causing the pressure-applying component 21 and the frame 11 to move closer to each other.

[0033] When using the oxygen bag pressurization device of this embodiment, first fill the oxygen bag 5 with oxygen, then simultaneously pull the frame 11 and the pressure-applying component 21 to both sides, causing the straps 31 to extend and the pressurization device to be placed over the oxygen bag 5. It is important to note that both sides of the oxygen bag 5 must have straps 31. Then adjust the angle of the oxygen bag 5 so that the frame 11 and the pressure-applying component 21 are respectively placed over two opposite corners of the oxygen bag 5. Due to the elastic contraction force of the spring, the straps 31 transmit a pulling force towards the frame 11 to the pressure-applying component 21, thereby ensuring that the frame 11 and the pressure-applying component 21 consistently apply pressure to the oxygen bag 5.

[0034] The oxygen bag pressurization device of this embodiment, by setting up a bottom unit 1, a pressure application unit 2, and a telescopic unit 3, can automatically maintain a stable oxygen supply flow without manual pressing, thereby reducing the workload of medical staff and improving the efficiency of oxygen use. This oxygen bag pressurization device is applicable to existing general-purpose oxygen bags without any modifications, and is simple in structure, quick to operate, lightweight, portable, and does not occupy storage space.

[0035] For example, such as Figure 1 , Figure 2 and Figure 3As shown, the telescopic unit 3 is equipped with four sets of straps 31 and telescopic components 32. The four sets of straps 31 and telescopic components 32 are symmetrically arranged on both sides of the symmetrical plane of the frame 11, so that when the pressurizing device is placed on the outside of the oxygen bag 5, two sets of straps 31 and telescopic components 32 are symmetrically arranged on both sides of the oxygen bag 5, so that the compression of the oxygen bag 5 by the frame 11 and the pressure application device 21 is relatively uniform, and the fixation of the oxygen bag by the pressurizing device is more stable.

[0036] To make the pressurization device more securely attached to the oxygen bag, the frame 11 is provided with an inclined annular inner wall so that one corner of the oxygen bag 5 can be securely attached to the inner wall of the frame 11, thereby making it less likely for the oxygen bag 5 to shift.

[0037] Preferred, such as Figure 1 As shown, the oxygen bag pressurization device in this embodiment also includes a flow measurement unit 4. The flow measurement unit 4 includes a flow sensor 41, a bidirectional connector 42, and a connecting strap 43. The flow sensor 41 is fixed to the bidirectional connector 42, and the two ends of the bidirectional connector 42 are respectively used to connect the outlet tube and the disposable oxygen delivery tube on the oxygen bag 5. The two ends of the connecting strap 43 are respectively fixedly connected to the bidirectional connector 42 and the pressure applying component 21. The flow sensor 41 is used to measure the oxygen flow rate and oxygen pressure output by the oxygen bag 5, and displays the measurement data on the display screen on the flow sensor 41 so as to adjust the flow control valve according to the patient's condition and provide the patient with a suitable oxygen delivery concentration.

[0038] Example 2

[0039] The difference between the oxygen bag pressurization device in this embodiment and that in embodiment 1 is that the frame 11 further includes a fixing component 112. The fixing component 112 can fix the stretched state of the spring spring. For example, it can fix the spring spring in the state where the strap 31 is fully extended, so that the oxygen pressure in the oxygen bag 5 is sufficient and the pressure in the oxygen bag 5 is not increased.

[0040] Specifically, such as Figure 4 and Figure 5 As shown, the fixing component 112 includes a limiting block 1121 and an elastic element 1122. A slot 113 is provided within the frame 11, and both the limiting block 1121 and the elastic element 1122 are located within the slot 113. One end of the elastic element 1122 is fixed to the slot 113. The limiting block 1121 is located between the strap 31 and the elastic element 1122, and the other end of the elastic element 1122 abuts against the limiting block 1121, enabling it to slide towards the strap 31. A latch 321 is provided at the connection end between the spring and the strap 31. The limiting block 1121 can be inserted into the latch 321 by the push of the elastic element 1122, thus fixing the spring in a stretched state.

[0041] The oxygen bag pressurization device in this embodiment, by setting the fixing component 112 and the slot 113, can prevent the oxygen bag 5 from being subjected to additional pressure when the oxygen pressure is sufficient, so that the oxygen output flow rate will not be too large and cause discomfort to the patient.

[0042] To increase the flexibility and reliability of the device, preferably, the limiting block 112 is L-shaped, and the slot 113 is stepped and provided with a first slot 1131 and a second slot 1132. Figure 5 As shown, the first locking platform 1131 is used to lock the limiting block 1121 in the position where the spring is stretched, so as to prevent the elastic element 1122 from pushing the limiting block 1121 to continue sliding towards the strap 31; the second locking platform 1132 is used to lock the limiting block 1121 in the position where the spring is released, so that the limiting block 1121 does not come into contact with the strap 31, thus avoiding interference with the contraction of the strap 31.

[0043] like Figure 5 As shown, the fixing component 112 also includes a handle 1123, one end of which is fixedly connected to the limiting block 1121, so that the position of the limiting block 1121 can be adjusted by operating the handle 1123. For example, there are two handles 1123, located on both sides of the oxygen bag, and each handle 1123 has a limiting block 1121 fixed at both ends.

[0044] In the initial state, the limiting blocks 1121 are engaged on the second locking platform 1132 by operating the handle 1123, causing the spring to be fully wound and the strap 31 to retract into the frame 11. When it is necessary to put the oxygen bag pressurization device of this embodiment onto the oxygen bag 5, the operating handle 1123 causes the limiting blocks 1121 to disengage from the second locking platform 1132. Under the push of the elastic member 1122, the limiting blocks 1121 slide towards the strap 31 until one end of the limiting blocks 1121 abuts against the strap 31. At the same time, the frame 11 and the pressure member 21 are pulled to both sides to extend the strap 31. When the locking slot 113 is pulled to the position of the limiting blocks 1121, one end of the limiting blocks 1121 is inserted into the locking slot 113 under the push of the elastic member 1122 until the first locking platform 1131 locks the limiting blocks 1121. The elastic spring is held in the extended position by the limiting block 1121, thus keeping the strap 31 in the fully extended state.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
