Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a medical gas mixing device. Background Technology

[0002] Medical gas mixing devices are used to uniformly mix different gases in the required proportions to form a mixed gas. This mainly involves injecting different gases into the mixer, mixing them, and then discharging them from the exhaust port. Traditional gas mixing devices are mostly simple gas injection and mixing devices, and they do not stir the gas to improve the uniformity of the mixture. In order to improve this situation, a medical gas mixing device is proposed.

[0003] For example, a medical gas mixing device disclosed in the authorization announcement number CN222446041U includes an air inlet box and an oxygen chamber and an air chamber inside the air inlet box. Electronic pressure gauges are installed at the positions of the air inlet box corresponding to the positions of the oxygen chamber and the air chamber. The electronic pressure gauges are connected to the controller by electrical signals. A first gas collecting hood is sealed inside one side of the air inlet box. A gas dispersing hood is sealed inside the air inlet box on the side of the first gas collecting hood. A second gas collecting hood is sealed inside the air inlet box on the side of the gas dispersing hood.

[0004] Although it enables the electronic pressure gauge to detect that the oxygen or air pressure in the oxygen chamber and air chamber is too high or too low, it can transmit the signal to the controller, which can control the output power of the corresponding variable frequency air pump, thereby facilitating timely control of the oxygen intake and air intake. By repeatedly dispersing and re-mixing oxygen and air in different directions, it ensures that the oxygen and air are mixed evenly.

[0005] However, the existing mixing device does not solve the problems of inconvenient linkage stirring and mixing of gases, adjustment of gas flow rate, uniform mixing of gases, and quick disassembly and replacement of filter blocks, which affect the effect and quality of gas mixing. Utility Model Content

[0006] The purpose of this invention is to provide a medical gas mixing device to solve the problems mentioned in the background art, such as the inconvenience of mixing devices in linking and stirring mixed gases and adjusting gas flow rate, which are not conducive to uniform mixing of gases and quick disassembly and replacement of filter blocks, thus affecting the effect and quality of gas mixing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a medical gas mixing device, comprising a connecting frame and a connecting pipe, wherein two sets of connecting pipes are arranged inside the connecting frame and are connected to each other, a mixing pipe is arranged on the side wall of the connecting frame and is fixedly connected to the connecting frame, and the connecting pipe is connected to the mixing pipe, an adjusting buckle is provided inside the connecting frame on one side of the connecting pipe and is slidably connected to the connecting frame, a servo motor is installed on the outer wall of the mixing pipe, a drive shaft is installed at the output end of the servo motor, a drive bevel gear is fitted on the surface of the drive shaft, and a placement rack is installed inside the mixing pipe on one side of the drive shaft.

[0008] Preferably, a driven shaft is provided at the center of the placement rack, and the driven shaft is movably connected to the placement rack.

[0009] Preferably, a driven bevel gear is fitted onto the driven shaft surface on one side of the transmission bevel gear, and the driven bevel gear meshes with the transmission bevel gear.

[0010] Preferably, a rotating frame is provided at the end of the driven shaft away from the driven bevel gear, and the rotating frame is fixedly connected to the driven shaft.

[0011] Preferably, the side wall of the rotating frame is provided with four sets of stirring blades at equal intervals, and the stirring blades are fixedly connected to the rotating frame.

[0012] Preferably, four sets of L-shaped grooves with equal spacing are installed on the inner wall of the mixing tube, and a filter block is provided inside the mixing tube on one side of the L-shaped groove.

[0013] Preferably, four sets of equally spaced limiting blocks are installed on the outer wall of the filter block, and the limiting blocks are slidably connected to the L-shaped groove.

[0014] Preferably, a rubber tube is provided inside the connecting frame on one side of the adjusting buckle, and the rubber tube is connected to the connecting pipe, and the adjusting buckle is slidably connected to the outer wall of the rubber tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the mixing device not only realizes convenient linkage stirring and mixing of gas and adjustment of gas flow rate, which facilitates uniform mixing of gas and quick disassembly and replacement of filter block, but also improves the effect and quality of gas mixing.

[0016] (1) By connecting the rubber tube to the connecting tube, the two sets of rubber tubes are then connected to two different external gas sources. The external gas enters the interior of the connecting tube through the rubber tube and is initially mixed in the connecting tube before entering the interior of the mixing tube. The initially mixed gas moves inside the mixing tube. The servo motor is turned on, and the servo motor drives the transmission bevel gear to rotate through the transmission shaft. The transmission bevel gear drives the driven shaft to rotate through the driven bevel gear. The driven shaft drives the rotating frame and stirring blade to rotate. The stirring blade stirs and mixes the initially mixed gas again to make the two gases more evenly mixed. The mixed gas is discharged after being filtered by the filter block. The filter block filters out the impurities inside to complete the mixing operation of the two gases. This realizes convenient linkage stirring and mixing of gas, which facilitates the uniform mixing of gas and improves the gas mixing effect.

[0017] (2) When the gas flow rate needs to be adjusted, slide the adjusting buckle. With the sliding cooperation between the adjusting buckle and the connecting frame, the adjusting buckle squeezes the rubber tube, which is similar to the regulator on the hose when administering saline solution to adjust the water flow. This adjusts the gas flow rate in the rubber tube to avoid excessive flow rate, which would cause uneven mixing of the two gases and affect the mixing effect. In addition, the filter block will become clogged after long-term use, which would weaken the filtration effect. When it needs to be replaced, rotate the filter block. The filter block will drive the limiting block to rotate inside the L-shaped groove. When the limiting block rotates to the turning position of the L-shaped groove, pull the filter block to remove it from the mixing tube. After replacing the filter block, repeat the above operation in reverse to install the filter block back into the mixing tube. This completes the quick disassembly and replacement of the filter block, realizing convenient adjustment of the gas flow rate and facilitating quick disassembly and replacement of the filter block.

[0026] Please see Figure 1-6 An embodiment of this utility model provides a medical gas mixing device, including a connecting frame 3 and a connecting pipe 7. The connecting frame 3 has two sets of connecting pipes 7 inside, and the two sets of connecting pipes 7 are connected. A mixing pipe 5 is provided on the side wall of the connecting frame 3, and the mixing pipe 5 is fixedly connected to the connecting frame 3. The connecting pipe 7 is connected to the mixing pipe 5. An adjustment buckle 2 is provided inside the connecting frame 3 on one side of the connecting pipe 7, and the adjustment buckle 2 is slidably connected to the connecting frame 3. A servo motor 4 is installed on the outer wall of the mixing pipe 5. The servo motor 4 plays the role of power driving. A transmission shaft 13 is installed at the output end of the servo motor 4. A transmission bevel gear 14 is fitted on the surface of the transmission shaft 13. A placement rack 8 is installed inside the mixing pipe 5 on one side of the transmission shaft 13.

[0027] Connect rubber tube 1 to connecting tube 7, and then connect the two sets of rubber tubes 1 to two different external gas sources respectively. The external gas enters the interior of connecting tube 7 through rubber tube 1 and is initially mixed in connecting tube 7 before entering the interior of mixing tube 5. The initially mixed gas moves inside mixing tube 5. Servo motor 4 is turned on, and servo motor 4 drives transmission bevel gear 14 to rotate through transmission shaft 13. Under the mutual meshing of transmission bevel gear 14 and driven bevel gear 11, transmission bevel gear 14 drives driven shaft 12 to rotate through driven bevel gear 11. Driven shaft 12 drives rotating frame 10 and stirring blade 9 to rotate. Stirring blade 9 stirs and mixes the initially mixed gas again to make the two gases more evenly mixed. The mixed gas is discharged after being filtered by filter block 6. Filter block 6 filters out the impurities inside it to complete the mixing operation of the two gases. It realizes convenient linkage stirring and mixing of gas, facilitates uniform mixing of gas, and improves the gas mixing effect.

[0028] A driven shaft 12 is provided at the center of the placement frame 8, and the driven shaft 12 is movably connected to the placement frame 8. A driven bevel gear 11 is fitted on the surface of the driven shaft 12 on one side of the transmission bevel gear 14, and the driven bevel gear 11 meshes with the transmission bevel gear 14.

[0029] A rotating frame 10 is provided at the end of the driven shaft 12 away from the driven bevel gear 11, and the rotating frame 10 is fixedly connected to the driven shaft 12. Four sets of stirring blades 9 are provided on the side wall of the rotating frame 10 at equal intervals, and the stirring blades 9 are fixedly connected to the rotating frame 10.

[0030] Four sets of L-shaped grooves 15 with equal spacing are installed on the inner wall of the mixing tube 5. A filter block 6 is installed inside the mixing tube 5 on one side of the L-shaped groove 15. Four sets of limiting blocks 16 with equal spacing are installed on the outer wall of the filter block 6, and the limiting blocks 16 are slidably connected to the L-shaped groove 15.

[0031] The connecting frame 3 on one side of the adjusting buckle 2 is equipped with a rubber tube 1, and the rubber tube 1 is connected to the connecting pipe 7. The adjusting buckle 2 is slidably connected to the outer wall of the rubber tube 1.

[0032] When the gas flow rate needs to be adjusted, slide the adjusting buckle 2. With the sliding cooperation between the adjusting buckle 2 and the connecting frame 3, the adjusting buckle 2 squeezes the rubber tube 1, similar to the regulator on the hose used to adjust the water flow when administering saline solution. This adjusts the gas flow rate in the rubber tube 1, preventing excessive flow that could lead to uneven mixing of the two gases and affect the mixing effect. Furthermore, the filter block 6 may become clogged after prolonged use, resulting in a weakened filtration effect. When it needs to be replaced, rotate the filter block 6. The filter block 6 will drive the limiting block 16 to rotate inside the L-shaped groove 15. When the limiting block 16 rotates to the turning position of the L-shaped groove 15, pull the filter block 6 out of the mixing tube 5. After replacing the filter block 6, repeat the above operation in reverse to install the filter block 6 back into the mixing tube 5. This allows for quick disassembly and replacement of the filter block 6, enabling convenient adjustment of the gas flow rate and facilitating rapid disassembly and replacement of the filter block.

[0033] Working principle: Connect rubber tube 1 to connecting tube 7, then connect the two sets of rubber tubes 1 to two different external gas sources respectively. The external gas enters the interior of connecting tube 7 through rubber tube 1 and is initially mixed before entering the interior of mixing tube 5. The initially mixed gas moves inside mixing tube 5. Servo motor 4 drives transmission bevel gear 14 to rotate through transmission shaft 13. Transmission bevel gear 14 drives driven shaft 12 to rotate through driven bevel gear 11. Driven shaft 12 drives rotating frame 10 and stirring blade 9 to rotate. Stirring blade 9 further stirs and mixes the initially mixed gas to make the two gases more evenly mixed. The mixed gas is discharged after being filtered by filter block 6, which removes impurities, thus completing the mixing operation of the two gases. When it is necessary to adjust the external gas intake... When adjusting the flow rate, slide the adjusting buckle 2. With the sliding cooperation between the adjusting buckle 2 and the connecting frame 3, the adjusting buckle 2 squeezes the rubber tube 1, similar to the regulator on the tubing used to adjust the water flow during an IV drip. This adjusts the flow rate of the gas in the rubber tube 1 to avoid excessive flow causing uneven mixing of the two gases and affecting the mixing effect. Furthermore, the filter block 6 may become clogged after prolonged use, resulting in a weakened filtration effect. When it needs to be replaced, rotate the filter block 6. The filter block 6 will drive the limiting block 16 to rotate inside the L-shaped groove 15. When the limiting block 16 rotates to the turning position of the L-shaped groove 15, pull the filter block 6 to remove it from the mixing tube 5. After replacing the filter block 6, repeat the above operation in reverse to install the filter block 6 back into the mixing tube 5, thus completing the quick disassembly and replacement of the filter block 6. The above is the complete usage of the medical gas mixing device.
