Description

Technical Field

[0001] This invention relates to emergency medical equipment, specifically to a field emergency mechanical ventilation device. Background Technology

[0002] During field operations, soldiers may experience oxygen deprivation due to long marches or injuries, requiring rapid oxygen replenishment to prevent complications. Because field conditions are often limited, portable equipment is used, such as:

[0003] A breathing bag, such as the publication (announcement) number: CN109758656A, publication (announcement) date: 2019-05-17, discloses an automatic simple respirator for field first aid, including a mask, elastic band, compression bag, switch button, tidal volume adjustment button, rechargeable battery, MCU module, electric three-way T-type ball valve, miniature suction pump, flow monitoring device and filter device. This invention requires only the touch of a switch button and setting of the tidal volume level. Powered by a rechargeable battery, it drives an electric three-way T-ball valve. A program via an MCU module cycles the opening and closing of the valve's inlet and outlet. When the inlet is open, a miniature air pump is triggered, allowing air to enter the compressed air bladder. The inlet is equipped with a flow monitoring device and a filter. When the set tidal volume is reached, the inlet closes and the outlet opens, allowing gas to enter the mask. The electric three-way T-ball valve operates at a frequency of 16 times per minute, ensuring sufficient minute ventilation. This achieves automatic assisted ventilation, is simple to operate, has a small volume for easy portability, and is suitable for battlefield first aid.

[0004] An oxygen cylinder, as disclosed in publication (announcement) number CN106917954A, published (announcement) date: 2017-07-04, is a portable oxygen cylinder comprising a cylindrical valve body and a high-pressure gas cylinder, the valve body being fixedly connected to the high-pressure gas cylinder; a pressure regulating valve and a flow regulating valve are provided inside the valve body, and a low-pressure gas chamber is provided at the top of the valve body; one end of the pressure regulating valve is connected to the high-pressure gas, and the other end is connected to the flow regulating valve, and one end of the flow regulating valve is connected to the pressure regulating valve, and the other end is connected to the low-pressure gas chamber; one end of the low-pressure gas chamber is connected to the flow regulating valve, and the other end is provided with an outlet pipe.

[0005] In the prior art, including the aforementioned patents, breathing bags are the preferred choice to reduce weight during marches.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-4 As shown, a field first aid mechanical ventilation device includes a main body 1 with an open top, a composite gas cylinder 2 is installed inside the main body 1, and the output end of the composite gas cylinder 2 is connected to one end of an oxygen tube 3 coiled inside the open top.

[0038] A piston rod 4 is provided inside the composite gas cylinder 2. The piston rod 4 includes a composite piston 41 located inside the composite gas cylinder 2 to maintain piston movement, and the composite piston 41 fits the contour of the composite gas cylinder 2.

[0039] Below the main body 1, there is an equipment box 5. Inside the equipment box 5, there is a drive mechanism 6 that drives the compound piston 41 to move. The drive mechanism 6 includes a crank disk 62 driven by a motor 61.

[0040] Specifically, in the above embodiment, the piston rod 4 includes a piston rod 42 axially connected to the composite piston 41. A one-way air inlet valve is provided on the piston rod 42, and the equipment box 5 includes an air inlet with an activated carbon filter plate 7. When the motor 61 drives the crank disk 62 to rotate, it pulls the piston rod 4 into the composite gas cylinder 2, maintaining piston movement. Its reciprocating stroke includes a pushing stroke and a suction stroke. During the suction stroke, gas enters between the composite piston 41 and the composite gas cylinder 2, and the entering gas is filtered by the activated carbon filter plate 7.

[0041] In the aforementioned technology, the piston rod 4, driven by the motor 61, reciprocates within the composite gas cylinder 2, rapidly drawing outside gas into the cylinder and pushing it into the oxygen cannula 3, thereby quickly replenishing oxygen for soldiers suffering from hypoxia. Furthermore, the entire device is electrically driven, allowing for operation by a single person without the need for assistance from others, fully considering the practical needs of field operations.

[0042] As a further embodiment of the present invention, the composite gas cylinder 2 includes:

[0043] Cylinder 21;

[0044] The elastic connecting rod 22 circumferentially arranged at one end of the cylinder 21 and the elastic silicone part 23 disposed between every two elastic connecting rods 22 form a deformable part;

[0045] An elastic silicone cap that seals the port of the deformable part;

[0046] Among them, the piston stroke of the composite piston component 41 is the length of the deformed part.

[0047] Furthermore, the composite piston component 41 includes a coupling component 411 and multiple rubber webs 412 arranged sequentially on the coupling component 411.

[0048] The radii of the multiple rubber circular webs 412 decrease sequentially from the one closest to the elastic silicone cap.

[0049] Furthermore, the main body 1 is rotatably provided with screws 8 arranged in a circular array;

[0050] It also includes a conical cover 81, which slides with the deformable part so that the circumference of the deformable part near the end of the elastic silicone cover is adjustable;

[0051] The conical cover 81 is threadedly assembled with multiple screws 8.

[0052] Specifically, in this embodiment, the multiple screws 8 rotate synchronously, thereby driving the conical cover 81 to move upward or downward. Because the inner wall cross-section of the conical cover 81 is a conical structure, during the downward movement, the port of the deformation part of the welding wire contracts, thus reducing the internal space of the deformation part. Since the speed of the motor 61 in this embodiment is fixed, by changing the internal space of the deformation part, the amount of oxygen supplied to the patient can be changed, avoiding the need for a large amount of oxygen to be compensated after a predetermined period of hypoxia following the initial gas supply, which could cause complications.

[0053] As another embodiment of the present invention, it further includes a second sprocket 83 that meshes with a first sprocket 82 fixedly disposed on the screw 8, and a plurality of second sprockets 83 are synchronously connected by a transmission belt.

[0054] It also includes a second bevel gear 832 that meshes with the first bevel gear 831 on the second spur gear 83.

[0055] Specifically, in this embodiment, the drive motor drives the second bevel gear 832 to rotate, thereby causing multiple second spur gears 83 to rotate synchronously under the action of the synchronous belt, thus fulfilling the need to drive the conical cover 81 to move up or down.

[0056] As a further embodiment of the present invention, a lever 63 is rotatably provided inside the device box 5, and the first end of the lever 63 is rotatably connected to the first connecting rod 64 eccentrically rotatably provided on the crank disk 62.

[0057] Furthermore, a second connecting rod 65 is rotatably connected between the second end of lever 63 and piston rod 42.

[0058] Specifically, the structure of lever 63 used in the embodiment can reduce the effort-saving effect, thereby reducing the operating load of motor 61 caused by the damping force of piston movement during operation.

[0059] As a further embodiment of the present invention, a cap 9 is snapped into the opening. This cap is used to cover the oxygen cannula 3 placed in the opening to prevent leakage.

[0060] As another embodiment of the present invention, the device box 5 is equipped with a rechargeable battery, a circuit board, and a control switch. Specifically, the outer wall of the main body 1 in this embodiment is a photovoltaic panel, which can be used to collect current to replenish the rechargeable battery, and the motor 61 and drive motor can be controlled by the control switch.

[0061] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
