Description

Technical Field

[0001] This utility model relates to the field of oxygen supply device technology, and in particular to a portable pressurized oxygen supply device. Background Technology

[0002] It is a simple device for artificial ventilation, suitable for oxygen supply in emergency situations such as acute respiratory failure and respiratory arrest. It can replace mouth-to-mouth breathing to increase the oxygen concentration. The device consists of an elastic breathing bag, breathing valve, gas storage bag, mask and oxygen interface, etc. It is characterized by simple structure and easy to carry. Its working principle is to manually squeeze the breathing bag to force oxygen into the patient's lungs through the mask or endotracheal tube.

[0003] However, some existing portable pressurized oxygen delivery devices typically supply air by manually pressing the air bag. This method can lead to insufficient gas supply, resulting in low oxygen delivery pressure and an inability to adjust the pressure, thus reducing the device's effectiveness. Furthermore, during pressurized oxygen delivery, external air is directly drawn in, which contains a lot of dust, potentially affecting patients in emergencies. Therefore, these issues need to be addressed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable pressurized oxygen supply device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A portable pressurized oxygen delivery device includes an oxygen delivery cylinder. A movable plate is slidably connected inside the oxygen delivery cylinder. A gas tube is fixedly connected to the center of one side of the movable plate. A connecting cylinder is provided at one end of its surface and is fixedly connected to one end of the gas tube. An inflation mechanism is provided inside the oxygen delivery cylinder. A first fixing ring is fixedly connected to the outer surface of the connecting cylinder. A buffer cylinder is fixedly connected inside the first fixing ring. A buffer mechanism is provided inside the buffer cylinder. An outlet pipe is fixedly connected to the end of the connecting cylinder away from the oxygen delivery cylinder. A second one-way valve is installed inside the outlet pipe. The buffer cylinder facilitates pressure buffering during oxygen pressurization and also restricts piston sliding. The device can be adjusted according to different usage requirements to improve its effectiveness.

[0006] Preferably, the inflation mechanism includes a sealing ring, a circular groove is formed on the outer surface of the movable piece, the sealing ring is slidably sleeved inside the circular groove, multiple communicating grooves are formed inside the movable piece, all of which are connected to the inside of the air pipe, a first air vent is formed on the surface of the oxygen supply cylinder away from the connecting cylinder, multiple first magnets are fixedly connected to the surface of the oxygen supply cylinder, a first cover plate is provided on one end of the surface of the oxygen supply cylinder, a first filter screen is provided between the oxygen supply cylinder and the first cover plate, a first air inlet is formed on the surface of the first cover plate, and multiple second magnets are fixedly connected to the surface of the first cover plate near the oxygen supply cylinder. The oxygen supply cylinder is equipped with a second cover plate at the other end of its surface, which is connected to multiple first magnets. The second cover plate has a second air inlet and a second filter screen inside. The second cover plate also has a third one-way valve body inside. The movable plate is slidably connected between the first and second cover plates. The second cover plate is sleeved on the outer surface of the air pipe. The air pipe is fixedly connected to the surface of the connecting cylinder. One end of the air pipe is inserted into the connecting cylinder. The air pipe is connected to the inside of the connecting cylinder, so that the connecting cylinder can be inflated while the movable plate slides back and forth inside the oxygen supply cylinder, thereby improving the efficiency of oxygen supply.

[0007] Furthermore, the buffer mechanism includes a spring, a piston is slidably sleeved inside the buffer cylinder, a limit ring is sleeved inside the first fixed ring, the piston is located on the top of the limit ring, a sliding rod is fixedly connected to the center of one side of the piston surface, a cover plate is installed on the top of the buffer cylinder, the sliding rod passes through the surface of the cover plate, the spring is sleeved inside the buffer cylinder, the spring is sleeved on the outer surface of the sliding rod, the bottom end of the spring is located on the top of the piston, the top end of the spring is located on the surface of the cover plate, and a limiting mechanism is provided on the surface of the cover plate to limit the piston's sliding, which is used to limit the piston's up and down sliding, so as to prevent excessive pressure during the oxygen pressurization process, and can store oxygen inside the buffer cylinder, while also releasing oxygen inside the buffer cylinder.

[0008] Preferably, the limiting mechanism includes a limiting piece, a knob is provided on the top of the cover plate, the knob is fixedly connected to the top of the slide rod, the buffer cylinder is internally connected to the connecting cylinder, a second fixing ring is sleeved on the outer surface of the slide rod, the second fixing ring is provided at the bottom of the knob, two connecting blocks are fixedly connected to the top of the cover plate, and each of the two connecting blocks has a slot inside. Two limiting pieces are fixedly connected to the outer surface of the second fixing ring, and there are two limiting pieces. The two limiting pieces cooperate with the two slots respectively, so that the two limiting pieces can be restricted inside the two buffer cylinders, which facilitates the restriction of the piston position, thereby improving the oxygen supply and pressurization effect.

[0009] Furthermore, the first and second filters are made of non-woven fabric, and both filters have an activated carbon layer inside to filter dust in the air during oxygen supply, thereby improving the effectiveness of the device.

[0010] The beneficial effects of this utility model are as follows: 1. By repeatedly sliding the oxygen supply cylinder and the connecting cylinder closer and further apart, the movable plate will slide back and forth inside the oxygen supply cylinder. Under the action of the first and third one-way valves and the sliding seal, the gas at the end of the movable plate inside the oxygen supply cylinder will be compressed. At the same time, the compressed gas will enter the gas pipe through the circular groove and multiple connecting grooves under the sealing ring, thus improving the oxygen supply effect.

[0011] 2. During use, as the movable disc slides, the sliding disc inside the oxygen cylinder will draw in outside air when it slides in the opposite direction. At the same time, the first and second filters will filter out dust in the air, thus improving the purity of the air.

[0012] 3. When the air pressure inside the connecting cylinder is too high during use, the gas will also compress the piston, causing it to slide. At the same time, it will also compress the spring. The sliding of the piston will cause the slide rod and knob to slide outward, thus buffering the pressure inside the connecting cylinder. When higher pressure is required, the knob can be turned manually to slide the two limit plates into the two slots respectively, thereby restricting the piston and slide rod. This allows for higher pressure during use, thereby improving the effectiveness of the device. Attached Figure Description

[0018] In this utility model, the buffer mechanism includes a spring 63, a piston 6 is slidably sleeved inside the buffer cylinder 3, a limiting ring 28 is sleeved inside the first fixing ring 27, the piston 6 is located on the top of the limiting ring 28, a sliding rod 61 is fixedly connected to the center of one side of the piston 6, a cover plate 31 is installed on the top of the buffer cylinder 3, the sliding rod 61 is inserted through the surface of the cover plate 31, the spring 63 is sleeved inside the buffer cylinder 3, the spring 63 is sleeved on the outer surface of the sliding rod 61, the bottom end of the spring 63 is located on the top of the piston 6, and the top end of the spring 63 is located on the surface of the cover plate 31.

[0021] Working principle: During use, the oxygen supply cylinder 1 and connecting cylinder 2 can be manually held and slid back and forth, bringing them closer and further apart. This causes the movable plate 22 to slide back and forth inside the oxygen supply cylinder 1. Under the action of the first one-way valve body 13 and the third one-way valve body 53, and through the sliding seal of 24, the gas at the end of the movable plate 22 sliding towards the inside of the oxygen supply cylinder 1 is compressed. Simultaneously, the compressed gas, blocked by the sealing ring 24, enters the air pipe 21 through the circular groove and multiple connecting grooves 23. While the movable plate 22 slides, the opposite end of the movable plate 22 inside the oxygen supply cylinder 1 draws in external air.

The system filters dust from the air, and the gas entering the connecting cylinder 2 is transported through the outlet pipe 25 and the second one-way valve body 26. During use, when the air pressure inside the connecting cylinder 2 is too high, the gas will also compress the piston 6, causing the piston 6 to slide.
