Description

Technical Field

[0001] This invention relates to the field of respiratory medicine nursing technology, and in particular to a humidified oxygen inhalation nursing device. Background Technology

[0002] Oxygen therapy is used to correct hypoxia, increase arterial blood oxygen partial pressure and oxygen saturation, and promote metabolism. It is an important adjunctive treatment for many diseases, such as respiratory failure, chronic bronchitis, cerebrovascular disease, and coronary heart disease. Even patients with mild or no clinical hypoxia may have oxygen debt or microcirculatory metabolic abnormalities, thus requiring oxygen therapy. Examples include patients before and after certain surgical procedures, patients with massive hemorrhage and shock, patients with poor fetal heart sounds, or patients experiencing prolonged labor.

[0003] Currently available humidified oxygen therapy devices suffer from poor contact between the oxygen output and the aqueous solution. Insufficient aqueous solution in the device reduces oxygen humidity, which can affect the device's performance. The device also has issues with automatic aqueous solution replenishment and the oxygen delivery effect being affected by accidental detachment of the tube. Summary of the Invention

[0004] In view of this, the present invention provides a humidifying oxygen inhalation nursing device, which has a float ring, enabling the device to have better linkage, automatically adding water when the water level in the device is lower than a preset height and automatically stopping after the water level is filled, thus avoiding the oxygen humidity from being reduced due to insufficient water level in the device, which would affect the device's performance.

[0006] Furthermore, a set of limiting posts are fixedly installed on the outer end slide rod of the limiting block, and a set of first elastic elements are sleeved on the slide rod, with the inner end of the first elastic element contacting the outer end face of the upper limit post of the slide rod.

[0007] Furthermore, a set of limiting rotating shafts is fixedly provided at the bottom of the oxygen inlet pipe, and a set of limiting rotating grooves is provided at the top of the branch pipe, with the limiting rotating grooves at the top of the branch pipe rotatably mounted on the limiting rotating shafts at the bottom of the oxygen inlet pipe.

[0008] Furthermore, the bracket is provided with a set of sliding holes, and a set of sliding rods are fixedly installed on the outer end of the limiting block, and the sliding rods at the outer end of the limiting block are slidably installed on the sliding holes of the bracket.

[0009] Furthermore, a set of threaded rods is fixedly connected to the bottom of the adjusting rod, and a set of threaded holes are opened on the guide block of the float ring, and the threaded holes on the float ring are threadedly installed on the threaded rods at the bottom of the adjusting rod.

[0010] Furthermore, a set of splined shafts is fixedly connected to the top of the driven gear, and a set of splined grooves are opened at the bottom of the branch pipe on the oxygen inlet pipe, and the splined grooves at the bottom of the branch pipe on the oxygen inlet pipe are snapped onto the splined shafts at the top of the driven gear.

[0011] Furthermore, a set of second elastic elements is respectively sleeved on the guide rods at both ends inside the water inlet pipe, and the bottom of the second elastic elements is in contact with the top surface of the connecting plate on the connecting rod.

[0012] Furthermore, a set of guide rods is fixedly installed at both ends of the inside of the water inlet pipe, and a set of connecting plates is fixedly installed at both ends of the connecting rod on the sealing cylinder. A set of sliding holes is opened on the connecting plates, and the sliding holes on the two sets of connecting plates are slidably installed on the guide rods at both ends of the inside of the water inlet pipe.

[0013] Furthermore, a set of guide grooves is provided at the bottom of the connecting rod, and a set of guide blocks are fixedly connected to the top of the floating ring, with the guide blocks at the top of the floating ring slidably mounted on the guide grooves at the bottom of the connecting rod.

[0014] Furthermore, a set of driven gears is rotatably mounted on the bottom of the tank, and the top of the drive gear is fixedly mounted on the drive shaft of the motor, and the driven gear and the drive gear are meshed and connected for transmission.

[0015] Compared with the prior art, the humidifying oxygen inhalation nursing device of the present invention has the following beneficial effects: The rotation of the branch pipes, combined with the segmentation of oxygen bubbles by the dividing mesh plate, effectively improves the contact between the oxygen ejected through the branch pipes and the aqueous solution, resulting in better oxygen output performance. Furthermore, the float ring ensures good interoperability, automatically adding water when the aqueous solution level is below a preset height and automatically stopping after water addition is complete. This prevents insufficient aqueous solution from reducing oxygen humidity and affecting the device's performance, and also facilitates adjustment of the preset water level for automatic water addition. Limiting blocks provide excellent connection control for the oxygen intake pipe, oxygen inlet pipe, and water inlet pipe, preventing accidental detachment of the pipes and ensuring optimal oxygen intake.

[0016] In addition, the motor drives the drive gear to rotate, which in turn drives the branch gas pipe at the bottom of the oxygen inlet pipe to rotate in the aqueous solution inside the tank. Combined with the four-point pipe structure of the branch gas pipe and the dividing mesh plate that is snapped into the mounting groove on the top of the tank, the contact effect between the oxygen sprayed through the branch gas pipe and the aqueous solution is effectively improved, so that the oxygen output of the device has a better performance.

[0017] Furthermore, when the aqueous solution level in the device is lower than the preset height, the connecting rod moves the sealing cylinder downward under the action of the second elastic element on the guide rod until it connects to the inner end of the water inlet connector on the water inlet pipe. The water in the water inlet connector automatically flows into the tank through the connecting pipe. When the aqueous solution level in the device reaches the preset height, the sealing cylinder moves upward under the action of the buoyancy of the float ring to seal the inner end of the water inlet connector, thereby automatically stopping the water injection. This gives the device better linkage, enabling it to automatically inject water when the aqueous solution level in the device is lower than the preset height and automatically stop after the aqueous solution is injected. This avoids the oxygen and humidity from decreasing due to insufficient aqueous solution in the device, which would affect the device's performance. Rotating the adjusting rod allows the float ring to rise and fall relative to the sealing cylinder, making it easy to adjust the preset height position of the automatically added aqueous solution.

[0018] Furthermore, by pulling the limiting block outward until the oxygen inhalation connecting pipe moves to a fixed position, the limiting block is released. Under the action of the first elastic element on the slide rod, the limiting block moves inward and is locked onto the limiting ring groove of the oxygen inhalation connecting pipe. The installation structures of the oxygen inhalation connecting pipe, the oxygen inlet connecting pipe, and the water inlet connecting pipe are the same, so that the device has a better connection limiting effect on the oxygen inhalation connecting pipe, the oxygen inlet connecting pipe, and the water inlet connecting pipe, and avoids the device from accidentally dislodging due to force, which would affect the oxygen inhalation effect of the device.

[0036] The specific usage and function of this embodiment: In this invention, the limiting groove 3021 at the top of the branch pipe 302 is rotatably mounted on the limiting shaft 301 at the bottom of the oxygen inlet pipe 3.

The driven gear 102 and the drive gear 1031 are meshed and connected. The motor 103 drives the drive gear 1031 to rotate, thereby driving the branch pipe 302 at the bottom of the oxygen inlet pipe 3 to rotate in the aqueous solution in the tank 1. Combined with the four-part pipe structure of the branch pipe 302 and the dividing mesh plate 4 snapped onto the mounting groove 101 at the top of the tank 1, the flow rate through the branch pipe 302 is effectively improved. 2. The contact effect between the sprayed oxygen and the aqueous solution is optimized to ensure better oxygen output performance of the device. The sliding holes on the two sets of connecting plates 5042 are slidably installed on the guide rods 505 at both ends inside the water inlet pipe 5. When the aqueous solution level in the device is lower than the preset height, under the action of the second elastic element 5051 on the guide rod 505, the connecting rod 5041 drives the sealing cylinder 504 downwards until the inner end of the water inlet connector 501 on the water inlet pipe 5 is connected. The water in the water inlet connector 501 automatically flows through the connecting pipe 503 into the tank 1. When the aqueous solution level in the device reaches the preset height, under the buoyancy of the float ring 506, the sealing cylinder 504 moves upwards to seal the inner end of the water inlet connector 501, thus automatically... The water filling is stopped, which improves the device's interlocking capability. It automatically fills water when the water level is below a preset height and automatically stops filling after the water level is complete. This prevents insufficient water level from reducing oxygen and humidity, which could affect the device's performance. The guide block 5061 at the top of the float ring 506 is slidably mounted on the guide groove 5043 at the bottom of the connecting rod 5041. The threaded hole 5062 on the float ring 506 is threaded onto the threaded rod 5071 at the bottom of the adjusting rod 507. Rotating the adjusting rod 507 allows the float ring 506 to rise and fall relative to the sealing cylinder 504, facilitating adjustments to the preset water level for automatic water filling. The sliding rod 2041 at the outer end of the limiting block 204 is slidably mounted... On the sliding hole of the bracket 203, the oxygen inhalation connecting pipe 202 is sleeved and installed on the top of the outlet pipe 201. Pull the limiting block 204 outward until the oxygen inhalation connecting pipe 202 moves to a fixed position. Then, release the limiting block 204. Under the action of the first elastic element 2042 on the slide rod 2041, the limiting block 204 moves inward and is locked onto the limiting ring groove 2021 of the oxygen inhalation connecting pipe 202. The installation structure of the oxygen inhalation connecting pipe 202, the oxygen inlet connecting pipe 205, and the water inlet connecting pipe 206 is the same, so that the device has a better connection limiting effect on the oxygen inhalation connecting pipe 202, the oxygen inlet connecting pipe 205, and the water inlet connecting pipe 206, and avoids the device from accidentally dislodging due to force, which would affect the oxygen inhalation effect of the device.
