Description

Technical Field

[0001] This utility model relates to the field of medical air detection technology, specifically an integrated device for air sampling and detection in a medical air pressurized oxygen chamber. Background Technology

[0002] A medical pressurized oxygen chamber is a medical device used to provide a high-concentration oxygen environment, widely applied in hypoxic diseases, wound repair, and rehabilitation. Due to factors such as airflow, equipment operation, and changes in patient position, the oxygen distribution within the chamber is not uniform, and the oxygen concentration may vary significantly at different heights and directions, affecting the patient's oxygenation effectiveness. Therefore, it is necessary to sample and test the air within the chamber.

[0003] Existing oxygen chamber air detection devices typically use fixed sampling probes, which are fixed at a specific location inside the oxygen chamber to sample and detect the air in that area. These fixed sampling probes can only monitor the air conditions in a specific area of ​​the oxygen chamber and cannot comprehensively reflect the oxygen distribution at different heights and directions within the chamber. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and provide an integrated device for air sampling and detection in a medical air pressurized oxygen chamber. This device should be able to comprehensively and accurately sample and detect the air in the oxygen chamber.

[0005] The technical solution of this utility model is:

[0006] The integrated air sampling and detection device for medical air pressurized oxygen chamber is characterized by comprising a main support, an air collection cylinder with a detector, a drive mechanism that drives the air collection cylinder to move up and down and rotate on the main support, and a controller that electrically connects the drive mechanism and the detector.

[0007] The main support includes a base and a guide cylinder vertically fixed on the base; the cylinder wall of the guide cylinder is provided with a spiral guide rail.

[0008] The drive mechanism includes a motor fixed to the top of the guide cylinder, a screw rotatably positioned in the guide cylinder about a vertical axis and coaxially connected to the motor shaft, a threaded sleeve meshing with the screw, and a slider that can slide along the guide rail and connect to the threaded sleeve.

[0009] The helical direction of the guide rail is opposite to the helical direction of the screw thread.

[0010] The inner cavity of the gas collecting cylinder is equipped with a gas collecting hood arranged coaxially front and back and the detector.

[0011] The gas collection hood is curved in an arc; the gas collection hood is a trumpet shape that is larger in the front and smaller in the back.

[0012] The gas collecting cylinder is arranged horizontally, with its front and rear sections at the same horizontal level.

[0013] The gas collecting cylinder is arranged at an angle, with the front of the cylinder higher than the rear.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses the height and orientation of the air collection cylinder to sample air at different locations and angles within the oxygen chamber, ensuring comprehensive and accurate detection of air conditions in different areas of the oxygen chamber. This design improves the representativeness of the detection data, thereby better assessing oxygen distribution and ensuring optimal oxygen therapy for patients.

[0016] 2. This utility model achieves the adjustment of the height and orientation of the gas collecting cylinder through a drive mechanism, which enables the gas collecting cylinder to remain stable during movement and avoids affecting the sampling accuracy due to the displacement or tilting of the gas collecting cylinder position. This design enhances the stability and reliability of the entire sampling device and improves the accuracy and repeatability of air detection. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figures 1 to 3 As shown, the integrated air sampling and detection device for medical air pressurized oxygen chamber includes a main support, a detector 23, an air collection cylinder 21, a drive mechanism, and a controller.

[0025] The detector is integrated inside the air collection cylinder. The drive mechanism is used to drive the air collection cylinder to move up, down and rotate on the main support to achieve air sampling at different positions and angles. The controller (omitted in the figure) is electrically connected to the drive mechanism and the detector.

[0026] The main support includes a base 11 and a guide cylinder 12. The base is horizontally arranged, and the guide cylinder is vertically fixed on the base. The guide cylinder is a cylindrical shell, and a spirally extending guide rail 121 is provided on the cylinder wall. The guide rail is a spiral groove formed on the cylinder wall, and the two sides of the guide rail are cylinder walls that maintain a certain distance.

[0027] The drive mechanism includes a motor 131, a screw 13, a threaded sleeve 14, and a slider 15. When the motor is working, it can drive the gas collecting cylinder to move up and down along the guide cylinder and rotate around the guide cylinder. The controller is electrically connected to the motor.

[0028] The motor is fixed to the top of the guide cylinder, with its shaft arranged vertically downwards. The screw is rotatably positioned within the guide cylinder about a vertical axis, coaxial with the guide cylinder, and the motor shaft is connected to the screw via a coupling. The threaded sleeve engages with the screw's threads. The slider can slide along the guide rail and is connected to the threaded sleeve. The air collecting cylinder is fixed to the slider.

[0029] The slider is provided with positioning grooves 15-1 on both sides, which slide and cooperate with the guide rail. The guide cylinder walls on both sides of the guide rail are embedded in the positioning grooves, which can effectively prevent the slider from shifting or tilting during the movement, ensuring that the air collecting cylinder maintains a stable height and direction during the movement, and preventing the accuracy of air sampling from being affected by positional shift.

[0030] The gas collecting hood is curved in an arc shape, with its inner arc surface facing the guide column, and its curvature matching the shape of the guide column. The front of the gas collecting cylinder is the airflow inlet and the rear is the airflow outlet. The inner cavity of the gas collecting cylinder is equipped with a gas collecting hood 22 and a detector arranged along the central axis. The gas collecting hood is fixed to the front of the inner cavity of the gas collecting cylinder, and the detector is fixed to the rear of the inner cavity of the gas collecting cylinder.

[0031] The gas collecting hood is flared, wider at the front and narrower at the back. The wider opening faces the front of the gas collecting cylinder and is fixed to the inner wall of the cylinder. The narrower opening faces the detector at the rear of the cylinder. The detector is fixed to the inner wall of the cylinder via a bracket 23-1. This design facilitates the guidance of gas into the detector, enabling it to accurately detect gas in a specific area and improving the applicability of the detector data.

[0032] When the motor is working, it drives the screw to rotate. Through the cooperation of the screw and the guide rail, the screw drives the threaded sleeve and the slider to rotate up and down along the spiral line under the constraint of the guide rail. This changes the height and direction of the air collecting cylinder, that is, changes the height and orientation of the air collecting hood. In this way, the detector 23 samples and tests the air at different heights and orientations in the medical air pressurized oxygen chamber to determine the position suitable for patients to stand for a long time or for patients to use, thereby improving the effect of oxygen inhalation for patients.

[0033] To ensure the gas collecting cylinder moves stably along the guide rail, the helix direction of the guide rail is opposite to that of the screw thread. This ensures that the screw, through the threaded sleeve, pushes the slider along the guide rail without deviation or jamming, thereby precisely adjusting the sampling and detection position and improving detection accuracy.

[0034] To facilitate measurements while stationary, the gas collecting cylinder is arranged horizontally, meaning the front and rear of the cylinder are at the same horizontal level. This ensures that gas enters the collecting cylinder horizontally during sampling, improving intake stability and measurement accuracy, and is particularly suitable for situations requiring stable sampling.

[0035] To facilitate measurements during movement, the gas collection cylinder is arranged at an angle, with the front of the cylinder higher than the rear. As the cylinder moves upwards, the airflow inlet at the front is always aligned with the direction of travel, allowing gas along the moving path to enter the cylinder stably. This ensures that more extensive and accurate air sample data are obtained within the sampling area, thereby improving the ability to detect air quality in different areas of the oxygen chamber.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
