Description

Technical Field

[0001] The invention relates to the field of hospital ward disinfection, and in particular to a short-range scanning high-energy pulse ultraviolet disinfection device. Background Art

[0002] Hospital wards are important places for patients to receive treatment, but they often become important media for bacterial growth and spread. The paths of microbial transmission include air transmission, aerosol transmission, etc. The currently commonly used ultraviolet disinfection method uses mercury lamps to destroy biological cell structures through ultraviolet rays with a wavelength of 200 to 280nm, thereby causing cell death to achieve a disinfection effect. However, mercury lamps contain mercury and are fragile, there is a possibility of chemical pollution, and their disinfection is often time-consuming, the intensity is unstable, and the range is not comprehensive. Simply using long-distance irradiation disinfection often has disinfection dead corners, resulting in microbial residues.

[0072] Preferably, the ultraviolet lamp tube comprises a core tube and a sleeve, wherein the core tube is sleeved outside the sleeve, and electrodes are respectively encapsulated at both ends of the core tube and the sleeve; wherein a cooling channel suitable for the flow of coolant is provided between the core tube and the sleeve, and the core tube is filled with xenon and argon.

[0073] Preferably, the ultraviolet disinfection device may also include an image acquisition module, an image segmentation and matching module, a path planning module and a database.

[0084] By integrating the above modules, the entire system can achieve a high degree of automation in obstacle detection, path planning, and disinfection task execution. Especially when dealing with dynamic obstacles, the system can adjust the path in real time, reduce delays, and improve overall efficiency.

[0085] Preferably, the working process is as follows: when the disinfection device is in operation, it first starts from the starting point, collects environmental information through information collection sensors, and realizes the collection of moving path information and obstacle information through three sensors at different heights; returns to the starting point, summarizes the information in the room through the display module, displays the main obstacle types, and automatically matches with the pre-stored obstacle information; relevant scanning plans are preset for different obstacles, and the preset method includes database import and robot arm recognition scanning entry; the preset planning content includes device stop points, scanning modes, and scanning time, wherein the scanning mode includes fixed scanning mode and three-dimensional scanning mode; the moving trajectory of the device and the movement trajectory of the arm are determined in combination with the moving path information and the stopping point information; then the device starts from the starting point again, executes according to the set moving path and arm movement path, and scans in turn at different stopping points, wherein the scanning execution is allocated in order, time, and intensity according to the scanning weight, returns to the starting point after completing all scans, summarizes and collects information through the display module, and performs relevant data statistical analysis on the scanning information of the obstacle information machine.

[0086] Planning logic:

[0087] a. Mobile path planning: After collecting mobile path information and obstacle information, the device lists the location of the stop points and adjusts the path according to the obstacle scanning stop points; the path gives priority to covering all the stop points, and the force arm is adjusted for the unreachable stop points, and the parts that cannot be scanned will be marked and feedback will be given;

[0088] b. Arm activity path: After the device reaches the obstacle stop point, the arm starts to move from the storage groove. After reaching a certain stop point, high-energy pulse ultraviolet disinfection is turned on. After the disinfection is completed, the arm mode is pre-adjusted according to the next stop point. After all obstacles are scanned, the arm is recovered to the storage groove. Different arm activity adjustments will be made for different scanning modes.

[0089] Scanning mode: including fixed scanning mode and stereo scanning mode

[0090] a. Fixed scanning mode: The first arm and the second arm are folded in the storage slot, and only the direction of the third arm is adjusted, including but not limited to the vertical horizontal plane and the parallel horizontal plane, to achieve single large-area scanning and disinfection of a single plane such as a wall or the ground; the implementation plan is: the third arm and the high-energy pulse ultraviolet device are fixed without secondary adjustment, and the device is moved at fixed intervals to achieve plane disinfection;

[0091] b. Stereoscopic scanning mode: The lever moves according to the plane of the obstacle. According to the different planes of the obstacle, the first lever unit, the second lever unit and the third lever unit are used to build a three-dimensional coordinate system to achieve multi-plane disinfection. After the device reaches the docking point, it stops moving and performs lever movement to analyze the obstacle. The docking time is the total time of the lever movement and scanning disinfection.

[0092] c. Traditional disinfection mode: All force arms are retracted and stored in slots, and the direction and distance of the high-energy pulsed ultraviolet lamp are manually adjusted. The scanning time is preset to achieve the traditional fixed-point disinfection mode; the disinfection area and disinfection time are manually controlled;

[0093] Scan weight and scan logic:

[0094] When the obstacle information is preset, the scanning weight is set according to the frequency of patient contact with the object, ranging from 0.5 to 1.0; different scanning modes and plans will be carried out for different weights. For low-weight objects, such as the ground and walls, they will be similar to a single plane or a simple cube; as the weight increases, the scanning surface will be more subdivided, and the scanning time will be appropriately extended. For more complex obstacles, they will be divided before scanning when the information is preset, and equivalently cut into different planes or cubes; the effective scanning area is equivalent to the area of ​​the high-energy pulse ultraviolet lamp tube; the effective scanning distance is preferably 15 to 20 cm; the scanning time is 10 to 15 seconds;

[0095] For example, a. Ground: The scanning weight is 0.5, and the fixed scanning mode is adopted. The arm activity is that the first arm and the second arm are folded in the storage slot, and the third arm is adjusted to make the high-energy pulse ultraviolet lamp scanning light perpendicular to the ground and the distance is 20 cm, and the time is 10 seconds; b. Bed: The scanning weight is 1.0, and the stereoscopic scanning mode is adopted. There are three stops for the bed, namely the head, middle and tail of the bed; when the device reaches the stop point at the head of the bed, because the head of the bed is often accompanied by obstacles such as bedside tables, the device path will not be able to reach the stop point accurately. At this time, the arm activity planning is turned on, and the first arm unit is rotated in the direction of its arm parallel to the ground, and then the second arm unit is rotated horizontally and perpendicular to the first The lever arm, at this time, it can be seen from the top view that the first lever arm and the second lever arm are perpendicular to each other at 90 degrees in the horizontal plane, and then the third lever arm unit rotates in the vertical plane, so that it is perpendicular to the second lever arm unit in the vertical plane, close to the headrest of the bed, and performs scanning and disinfection; after the disinfection is completed, the third lever arm unit rotates to make the pulsed ultraviolet lamp perpendicular to the bed surface, and the second lever arm unit rotates in the same direction as the first lever arm unit, and the first lever arm unit does not move. The device moves to the middle stop of the bed for disinfection; due to the disinfection area, multiple stop points are often set in the middle of the bed; the device moves to the stop point at the end of the bed in turn, involving the end of the bed including two vertical planes and one horizontal plane at the end of the bed, and the lever moves and disinfects in turn according to the structure of the end of the bed.

[0096] The present invention can achieve one or more of the following technical effects:

[0097] The first lever unit, the second lever unit and the third lever unit which can pivot relative to each other cooperate with each other to achieve scanning-type close-range ultraviolet disinfection of various obstacles including three-dimensional obstacles, and disinfect various surfaces of the obstacles;

[0098] High-energy ultraviolet disinfection at a close distance of less than or equal to 20cm greatly improves the disinfection efficiency;

[0099] Directedly emitting high-energy pulsed ultraviolet rays in a first direction away from the third arm unit can realize the directionally emitting ultraviolet rays to the surface of obstacles, greatly reducing the risk of ultraviolet rays accidentally scanning the human body;

[0100] The infrared detection unit can be used to detect the presence, position and / or distance of a human body, and is used to further prevent the ultraviolet rays from accidentally scanning the human body during the posture adjustment and / or scanning process of the high-energy pulse ultraviolet lamp tube;

[0101] In storage mode, it can be used as a traditional remote disinfection device;

[0102] The priority setting unit ensures that high-risk obstacles such as hospital beds that have key contact with the human body are disinfected first, which can effectively reduce risks.

[0103] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
