Abstract
Description
Technical Field
[0001] This invention relates to the field of oxygen analyzer technology, and more particularly to a detection structure for a medical oxygen analyzer. Background Technology
[0002] In the hospital's central oxygen supply system, oxygen analyzers are installed at the output ends of equipment such as oxygen cylinders, ventilators, or anesthesia machines to monitor in real time whether the oxygen concentration meets the needs of diagnosis and treatment. For example, the purity of ordinary oxygen inhalation needs to be maintained at 21%-40%, while the purity of hyperbaric oxygen therapy needs to be ≥99.5%, thereby ensuring that patients receive a safe oxygen therapy dose.
[0003] Currently, after adding an oxygen analyzer, the oxygen may contain condensate from medical oxygen pipelines and oil residue from secretions in the ventilator circuit. In this case, filter cotton is needed to filter and adsorb these substances. However, in actual use, since the rate of water vapor and oil residue generation is not constant, the filter can only be replaced periodically. Replacing it too early would be wasteful, while delaying replacement would cause impurities to enter the sensors in subsequent processes, leading to an increased failure rate.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0022] Example 1: Reference Figures 1-5 A detection structure for a medical oxygen analyzer includes a housing 1, a detection component 2 disposed inside the housing 1, a collection component 3 disposed on the surface of the detection component 2, a filter component 4 disposed on the surface of the collection component 3, and a protective component 5 disposed on the surface of the filter component 4.
[0023] The detection component 2 includes an air inlet pipe 21 fixedly installed on the top right side of the outer casing 1. A connecting pipe 22 is fixedly connected to the bottom end of the air inlet pipe 21. An impurity processor 23 is fixedly connected inside the outer casing 1. Both the upper and lower ends of the impurity processor 23 are cylindrical, and the middle section connecting the upper and lower ends is a truncated cone with an inner diameter that gradually decreases from top to bottom. The axis of the connecting pipe 22 is tangentially connected to the inner wall of the upper truncated cone. A connecting pipe 24 is provided at the top of the impurity processor 23. A concentration detection sensor 25 is fixedly installed inside the outer casing 1. A connecting pipe 26 is fixedly connected to the output end of the concentration detection sensor 25. The top end of the connecting pipe 26 is fixedly connected to the outlet pipe 27. In this embodiment, after the external oxygen output terminal is connected to the inlet pipe 21, it is introduced into the interior of the impurity processor 23 through the connecting pipe 22. At this time, under the action of centrifugal force, the oil and water droplets with higher density slide down along the inner wall of the impurity processor 23, achieving preliminary separation, thereby collecting the oil and water droplets in the oxygen. The purified oxygen enters the interior of the concentration detection sensor 25 through the connecting pipe 24 for detection, and after detection, it enters the output terminal or is directly used by the patient through the connecting pipe 26 and the outlet pipe 27.
[0024] The collection assembly 3 includes a silicone one-way valve 31 fixedly installed at the bottom of the impurity processor 23. A collection cylinder 32 is provided at the bottom of the impurity processor 23. Insertion slots 33 are provided on both the left and right sides of the bottom surface of the impurity processor 23. An annular groove 34 is provided on the bottom surface of the impurity processor 23. Insert plates 35 are fixedly connected to both the left and right sides of the top of the collection cylinder 32. A telescopic rod 36 is fixedly connected to the inside of the top of the insert plate 35. A connecting spring 37 is fixedly connected to the top of the insert plate 35. A damping block 38 is fixedly connected to the top of the connecting spring 37. The top of the collection cylinder 32 contacts the bottom of the impurity processor 23. The insert plate 35 is adapted to pass through the insertion slot 33 and snaps into the inside of the annular groove 34. The top of the telescopic rod 36 is fixedly connected to... The damping block 38 is attached to the bottom end, and the top end of the damping block 38 is adapted to contact the top wall of the annular groove 34. In this embodiment, the impurities that slide down are collected inside the collection cylinder 32 through the silicone one-way valve 31. The inserted plate 35 passes through the insertion groove 33 and enters the annular groove 34. At this time, rotating the collection cylinder 32 causes the inserted plate 35 to rotate inside the annular groove 34, which can complete the quick installation and removal of the collection cylinder 32. The damping block 38 is pushed against the inner wall of the annular groove 34 by the elastic force of the connecting spring 37. The friction between the damping block 38 and the annular groove 34 makes the inserted plate 35 more stable inside the annular groove 34, which improves the stability after the collection cylinder 32 is installed.
[0025] Example 2: Reference Figures 6-10 A detection structure for a medical oxygen analyzer, which is another preferred embodiment of this invention, differs from Embodiment 1 in that the filter assembly 4 includes a lower connecting portion 401 fixedly installed inside the top of the impurity processor 23, a filter screen 402 fixedly installed inside the bottom end of the lower connecting portion 401, a middle connecting portion 403 provided at the top of the lower connecting portion 401, an absorbent cotton 404 fixedly connected to the inner wall of the middle connecting portion 403, an upper connecting portion 405 provided at the top of the middle connecting portion 403, and a support rod fixedly connected between the upper connecting portion 405 and the top of the impurity processor 23. The inner diameters of the lower connecting part 401, the middle connecting part 403, and the upper connecting part 405 are all the same. The bottom end of the connecting pipe 24 is inserted into the interior of the upper connecting part 405. In this embodiment, the middle connecting part 403 is installed between the lower connecting part 401 and the upper connecting part 405. At this time, the oxygen purified by the impurity processor 23 enters the interior of the middle connecting part 403 through the lower connecting part 401, and the small amount of water vapor remaining in the oxygen is further adsorbed by the adsorption cotton 404 on the inner wall of the middle connecting part 403, which further improves the purity of the oxygen. Then, the oxygen enters the interior of the connecting pipe 24 through the upper connecting part 405.
[0026] The upper and lower ends of the middle connecting part 403 are respectively provided with corresponding snap-fit slots between the lower connecting part 401 and the upper connecting part 405. During the installation of the middle connecting part 403, the friction force can be overcome to push the middle connecting part 403 into the space between the lower connecting part 401 and the upper connecting part 405. When the corresponding snap-fit slots are engaged, the position of the middle connecting part 403 can be ensured to be installed accurately.
[0027] An emergency U-shaped tube 406 is fixedly connected to the side wall at the top of the middle connecting part 403. An absorbent cotton 407 is fixedly connected to the inner wall of the emergency U-shaped tube 406. A humidity sensor 408 is fixedly installed inside the bottom of the emergency U-shaped tube 406. A solenoid valve 409 is fixedly installed inside the bottom of the emergency U-shaped tube 406. The top end of the emergency U-shaped tube 406 is fixedly connected to the side wall of the upper connecting part 405. Both ends of the emergency U-shaped tube 406 are connected to the middle connecting part 403 and the upper connecting part 405, respectively. A button battery is fixedly installed on the inner wall of the emergency U-shaped tube 406. The humidity sensor 408 is electrically connected to the button battery. The humidity sensor 408 is controlled by a microcontroller. The controller and solenoid valve 409 are electrically connected. In this embodiment, when the absorbent cotton 404 absorbs water vapor from the oxygen to saturation, and the operator does not replace the absorbent cotton 404 in time, the water content of the oxygen inside the central connecting part 403 will not decrease further. Therefore, the humidity sensor 408 detects an increase in the humidity of the surrounding environment. At this time, the humidity sensor 408 opens the solenoid valve 409 through the microcontroller, so that the bottom of the absorbent cotton 407 and the central connecting part 403 are connected. At this time, the oxygen containing water vapor will also enter the interior of the absorbent cotton 407, so that the water vapor in the oxygen is absorbed by the absorbent cotton 407, thereby achieving the purpose of emergency response.
[0028] In addition, during actual use, multiple emergency U-shaped tubes 406 can be installed on the surface of the central connecting part 403 to achieve a longer emergency effect. While the first absorbent cotton 404 is working normally, the oxygen through the central connecting part 403 is in a dry state. At this time, the dry oxygen enters the interior of the emergency U-shaped tube 406 from the top and will not affect the emergency effect of the second absorbent cotton 407.
[0029] A humidity-triggered elastic plug 410 is fixedly installed at the bottom of the central connecting part 403. The humidity-triggered elastic plug 410 is made of water-absorbing and expanding rubber. The water absorption and expansion rate of the humidity-triggered elastic plug 410 is slightly slower than the saturation rate of the absorbent cotton 404, ensuring that when the trigger switch 413 is pressed, the absorbent cotton 404 is just saturated, achieving accurate early warning. A fixing plate 411 is fixedly installed on the surface of the central connecting part 403. An alarm bell 412 is fixedly connected to the surface of the fixing plate 411. The end of the fixing plate 411 is close to the humidity-triggered elastic plug 410. A trigger switch 413 is fixedly connected, and the trigger switch 413 and the alarm bell 412 are electrically connected. In this embodiment, when the absorbent cotton 404 gradually reaches saturation, the humidity trigger elastic plug 410 is always in a state of water absorption and expansion to the limit. At this time, the expanded humidity trigger elastic plug 410 will contact the trigger switch 413, and the trigger switch 413 will be activated after being pressed, so that the alarm bell 412 will remind the operator to replace the central connecting part 403. Before replacement, the emergency U-shaped tube 406 will be used for emergency response.
[0030] Example 3: Reference Figures 10-11A detection structure for a medical oxygen analyzer, which is another preferred embodiment of this invention, differs from Embodiment 2 in that the protective component 5 includes an inner groove 51 formed inside the lower connecting part 401 and the upper connecting part 405 on their adjacent sides. Anti-slip plates 52 are slidably connected to both the left and right sides of the inner groove 51. A U-shaped plate 53 is fixedly connected to one end of each anti-slip plate 52 that is far apart from the other. A sliding plate 55 is slidably connected inside the U-shaped plate 53. A buffer telescopic member 54 is slidably connected inside the sliding plate 55. A locking block 56 is fixedly connected to the end of the sliding plate 55 away from the buffer telescopic component 54. A connecting component 57 is rotatably connected inside the end of the "U"-shaped plate 53 away from the anti-slip plate 52. The middle of the connecting component 57 is connected to both ends by a spring, which can prevent the sliding plate 55 from excessively pushing the connecting component 57 and causing mechanical damage. The lower connecting part 401 and the upper connecting part 405 have locking grooves 58 on the left and right sides of their near ends, and the two anti-slip plates 52 are adapted to contact each other. The end of the connecting component 57 away from the "U"-shaped plate 53 is rotatably connected to the end of the sliding plate 55 away from the locking block 56. Block 56 is fitted into the slot 58. In this embodiment, during the installation of the connecting part 403, the sliding plate 55 needs to be manually pushed to compress the buffer telescopic member 54 and drive the block 56 to engage inside the slot 58, so that the block 56 is flush with the top surface of the lower connecting part 401, and in the upper part, the block 56 is flush with the bottom surface of the upper connecting part 405. During the process of pushing the sliding plate 55, as the connection between the connector 57 and the sliding plate 55 approaches the interior of the U-shaped plate 53, the sliding plate 55 will... The connecting piece 57 pushes the U-shaped plate 53 to move away from the sliding plate 55, thus the U-shaped plate 53 will drive the anti-slip plate 52 to move outward from the inner groove 51. At this time, the two anti-slip plates 52 move away from each other, causing the lower connecting part 401 to open. Similarly, the upper connecting part 405 is opened. Then, the middle connecting part 403 can be pushed into the interior of the lower connecting part 401 and the upper connecting part 405, so that the upper and lower ends of the lower connecting part 401 contact the locking block 56 respectively and lock into the interior of the locking groove 58. At this time, the installation is completed.
[0031] When the absorbent cotton 404 reaches saturation, the middle connecting part 403 needs to be disassembled so that new absorbent cotton 404 can be used to absorb moisture. At this time, the middle connecting part 403 can be manually pushed to detach from the lower connecting part 401 and the upper connecting part 405. At this time, the locking block 56 also detaches from the lower connecting part 401. The sliding plate 55 will detach from the locking groove 58 under the rebound force of the buffer telescopic member 54. During the movement of the sliding plate 55, the connecting member 57 will pull the U-shaped plate 53 to move, so that the U-shaped plate 53 drives the anti-slip plate 52 to seal the interior of the lower connecting part 401. This ensures that even if the middle connecting part 403 is not installed at the close end of the lower connecting part 401 and the upper connecting part 405, the part itself remains sealed, minimizing the pollution of the interior by the external environment.
[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
