Description

Technical Field

[0001] The invention relates to first aid equipment, in particular to a field first aid mechanical assisted ventilation device. Background Art

[0002] When conducting field operations, due to long-distance raids or injuries, soldiers may suffer from hypoxia, so they need to quickly replenish oxygen to avoid complications caused by hypoxia. Therefore, field operation conditions are relatively limited, so portable equipment is used, such as:

[0003] A breathing bag, as disclosed in the publication (announcement) number: CN109758656A, the publication (announcement) date: 2019-05-17, discloses a field first aid automatic simple respirator, including a mask, an elastic belt, a compression air bag, a switch button, a tidal volume gear button, a rechargeable battery, an MCU module, an electric three-way T-type ball valve, a micro vacuum pump, a flow monitoring device and a filtering device. The present invention only needs to touch the switch button and set the tidal volume gear. It is powered by a rechargeable battery to drive the electric three-way T-type ball valve to work. The program is set through the MCU module to cyclically open the air inlet and the air outlet of the electric three-way T-type ball valve. When the air inlet is opened, the micro air pump is triggered to run, so that air enters the compressed air bag. The air inlet is equipped with a flow monitoring device and a filtering device. When the set tidal volume is reached, the air inlet is closed and the air outlet is opened, and the gas enters the mask through the air outlet. The electric three-way T-type ball valve runs at a frequency of 16 times / minute to ensure sufficient minute ventilation, thereby realizing automatic assisted ventilation. The operation is simple, the volume is small and it is easy to carry, and it is suitable for battlefield first aid.

[0036] In order 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 emergency mechanical assisted ventilation device comprises a main body 1 with an opening on the top, a composite gas cylinder 2 is arranged in the main body 1, and an output end of the composite gas cylinder 2 is connected to one end of an oxygen cannula 3 coiled in the opening;

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

[0039] A device box 5 is arranged below the main body 1 . A driving mechanism 6 for driving the composite piston member 41 to move is arranged in the device box 5 . The driving mechanism 6 includes a crank plate 62 driven by a motor 61 .

[0040] Specifically, the piston rod member 4 in the above embodiment includes a piston rod 42 axially connected to the composite piston member 41, a one-way air inlet valve is arranged on the piston rod 42, and the device box 5 includes an air inlet, and an activated carbon filter plate 7 is arranged on the air inlet. When the motor 61 drives the crank plate 62 to rotate, the piston rod member 4 is pulled to maintain the piston movement in the composite gas cylinder 2, and its reciprocating stroke includes a pushing stroke and a suction stroke. In the suction stroke, the gas will enter between the composite piston member 41 and the composite gas cylinder 2, and the entering gas will be filtered by the activated carbon filter plate 7.

[0041] In the above technology, the piston rod 4 is driven by the motor 61 to move back and forth in the composite gas cylinder 2, and the external gas is quickly sucked into the composite gas cylinder 2 and pushed into the oxygen cannula 3, so that the oxygen-deficient soldiers can quickly get oxygen supply. And the whole device is electrically driven, so it can be operated by one person without the cooperation of others, which fully considers the actual needs of field operations.

[0042] As an embodiment further provided by the present invention, the composite gas cylinder 2 comprises:

[0043] Cylinder 21;

[0044] An elastic connecting rod 22 circumferentially arranged at one end of the cylinder 21 and an elastic silicone member 23 arranged between every two elastic connecting rods 22 form a deformation portion;

[0045] An elastic silicone cover sealing the port of the deformation part;

[0046] The piston stroke of the composite piston member 41 is the length of the deformation portion.

[0047] Furthermore, the composite piston member 41 includes a coupling member 411 and a plurality of rubber round webs 412 sequentially stacked on the coupling member 411;

[0048] The radius of the multiple rubber round webs 412 decreases gradually from close to the elastic silicone cover.

[0049] Furthermore, screws 8 arranged in a circular array are rotatably disposed in the main body 1;

[0050] It also includes a conical cover 81, which is slidably matched with the deformation part so that the circumference of the deformation part close to one end of the elastic silicone cover is adjustable;

[0051] The conical cover 81 is threadably assembled with the plurality of screw rods 8 .

[0052] Specifically, the multiple screws 8 in the embodiment rotate synchronously, thereby driving the conical cover 81 to move up or down. Because the inner wall cross section of the conical cover 81 is a conical structure, the port of the deformation part of the welding wire will shrink during the downward movement, thereby reducing the internal space of the deformation part. Because the speed of the motor 61 in the embodiment is fixed, the amount of oxygen supplied to the patient can be changed by changing the internal space of the deformation part, avoiding the need to compensate for a large amount of oxygen after a predetermined period of hypoxia after a large amount of gas is added, which may cause complications.

[0053] As another embodiment further provided by the present invention, it also includes a second circular gear 83 meshing with the first circular gear 82 fixedly disposed on the screw rod 8, and a plurality of second circular gears 83 are synchronously connected via a transmission belt;

[0054] The second gear 832 is meshed with the first bevel gear 831 on the second circular gear 83 .

[0055] Specifically, the driving motor in the embodiment drives the second bevel gear 832 to rotate, so that under the action of the synchronous belt, the plurality of second circular gears 83 rotate synchronously, thereby realizing the requirement of driving the conical cover 81 to move up or down.

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

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

[0058] Specifically, the structure of the lever 63 is adopted in the embodiment to reduce the labor-saving effect, thereby reducing the problem of the operating load of the motor 61 caused by the damping force of the piston movement during operation.

[0059] As another embodiment further provided by the present invention, a cover 9 is clamped in the opening to cover the oxygen cannula 3 placed in the opening to prevent leakage.

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

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above 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.
