Description

An automatic disinfection device for ultrasound examination probes Technical Field

[0001] This application relates to the field of ultrasonic probe disinfection technology, and more specifically, to an automatic disinfection device for ultrasonic examination probes. Background Technology

[0002] Imaging ultrasound is a medical diagnostic technique based on ultrasound waves. It utilizes the reflection of ultrasound waves by the human body to observe the effects of these waves. By irradiating the body with weak ultrasound waves and processing the reflected waves from the tissues into images, the size, structure, and pathological lesions of muscles and internal organs can be visualized. Imaging ultrasound is a comprehensive application combining acoustics, medicine, optics, and electronics, providing doctors with a basis for analyzing lesions inside the body and improving the effectiveness of treatment based on the actual condition of the lesions.

[0003] When performing an ultrasound examination, doctors need to hold the ultrasound probe close to the skin near the lesion and irradiate it. After the examination, to avoid cross-infection between patients, the ultrasound probe needs to be cleaned and disinfected before the next patient can be examined. Disinfecting is usually done manually with disinfectant wipes. However, manual wiping is not only slow but also prone to missing areas, resulting in poor disinfection of the ultrasound probe.

[0033] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] An automatic disinfection device for an ultrasound examination probe according to an embodiment of this application is described below with reference to the accompanying drawings.

[0036] Please refer to Figures 1 to 9. An automatic disinfection device for an ultrasound examination probe according to an embodiment of this application includes:

[0037] The disinfection box 1 has a T-shaped mounting opening 11 on its front side. A fixed placement component 2 is slidably installed on the lower side of the T-shaped mounting opening 11. Limiting components 3 are installed on the lower left and right sides of the front side of the disinfection box 1 corresponding to the lower part of the T-shaped mounting opening 11.

[0038] Gear assembly 6, which consists of two sets and is symmetrically rotated between the front and rear side walls of the disinfection box 1;

[0039] The drive assembly 5 is installed on the upper side of one end of the fixed placement piece 2 located inside the disinfection box 1, and the drive assembly 5 is meshed with the gear assembly 6.

[0040] Ultraviolet disinfection component 9 is installed at the bottom of disinfection box 1;

[0041] The coupling agent heating component 8 is installed on the top of the disinfection box 1. The coupling agent heating component 8 is connected to the extrusion component 7, which is meshed with the gear component 6.

[0042] In this embodiment, the fixed placement component 2 supports and fixes the ultrasound probe, ensuring its stable placement within the disinfection chamber 1 during disinfection. As the fixed placement component 2 moves downward, the driving component 5 drives the gear assembly 6 to rotate, which in turn drives the ultraviolet disinfection component 9 to rotate. This allows the ultraviolet disinfection component 9 to surround the ultrasound probe, ensuring comprehensive disinfection and preventing blind spots that could lead to incomplete disinfection. Simultaneously, as the fixed placement component 2 moves downward, the gear assembly 6 drives the extrusion component 7 to move upward, filling the coupling agent heating component 8 with coupling agent. The heating component 8 heats the coupling agent, ensuring it is at a certain temperature to prevent discomfort to the patient upon contact with their skin. When the fixed placement component 2 moves upward, the extrusion component 7 moves downward, extruding the coupling agent stored in the heating component 8 onto the ultrasound probe, allowing the doctor to directly remove and use the probe.

[0043] Please refer to Figures 8-9. The upper part of the fixed placement component 2 has a U-shaped notch, and sliding slots are provided on both the left and right side walls of the fixed placement component 2. The fixed placement component 2 is slidably installed in the T-shaped mounting opening 11. Telescopic rods 21 are connected to the left and right sides of the U-shaped notch on the fixed placement component 2, respectively. The end of the telescopic rod 21 is connected to a locking block 23. A first spring 22 is sleeved on the telescopic rod 21. The cross-section of the locking block 23 is triangular. When the ultrasonic probe is placed on the fixed placement component 2, the handle of the ultrasonic probe squeezes the locking block 23 to move it to both sides, and the ultrasonic probe can then be inserted downward into the U-shaped notch on the fixed placement component 2. After the ultrasonic probe is placed, under the action of the first spring 22, the two locking blocks 23 move closer together again, and the ultrasonic probe on the fixed placement component 2 can be fixed.

[0044] When the fixed placement component 2 moves to its lowest position, a limiting component 3 is provided on the front side of the disinfection box 1 to prevent it from moving upwards again. The limiting component 3 includes a C-shaped frame 31, a sliding rod 32, and a second spring 33. The C-shaped frame 31 is fixedly installed on the front side of the disinfection box 1. The sliding rod 32 is installed between the upper and lower walls of the C-shaped frame 31. The fixed placement component 2 has symmetrical through holes 24 on the left and right sides at its front. The sliding rod 32 passes through the through holes 24 of the fixed placement component 2. The second spring 33 is sleeved on the sliding rod 32 on the lower side of the fixed placement component 2. By setting the sliding rod 32 inside the C-shaped frame 31, the fixed placement component 2 can be prevented from sliding out of the T-shaped mounting opening 11. The front left and right sides of the fixed placement component 2 are respectively provided with strip grooves 25. A slider 26 is movably installed in the strip groove 25. A trapezoidal block 27 is connected to the end of the slider 26. A strip hole communicating with the strip groove 25 is opened on the front side of the fixed placement part 2. A lever 28 is movably installed in the strip hole. One end of the lever 28 is fixedly connected to the slider 26. A slot 34 is opened on the inner side of the lower end of the C-shaped frame 31. When the fixed placement part 2 moves to the lowest position, the trapezoidal block 27 can be inserted into the slot 34. At this time, the fixed placement part 2 can be stably placed at the lowest position of the T-shaped mounting opening 11. When the fixed placement part 2 needs to be moved upward, the lever 28 is manually moved to make the slider 26 move into the strip groove 25. The trapezoidal block 27 can then be pulled out from the slot 34. At this time, the fixed placement part 2 can move upward.

[0045] Please refer to Figure 5. The gear assembly 6 includes a rotating shaft 61, a first gear 62, a second gear 63, and a third gear 64. The rotating shaft 61 is rotatably mounted between the front and rear side walls of the disinfection box 1. The first gear 62, the second gear 63, and the third gear 64 are fixedly mounted on the rotating shaft 61 in sequence.

[0046] Please refer to Figure 4. The drive assembly 5 includes a bent rod 51 and a first rack 52. There are two bent rods 51, which are symmetrically installed on the left and right ends of the rear side of the fixed placement member 2. The end of the bent rod 51 is connected to the first rack 52, which meshes with the first gear 62. The bent rod 51 can move up and down with the fixed placement member 2. When the fixed placement member 2 moves downward, the bent rod 51 and the first rack 52 move downward together, driving the gear assembly 6 to rotate.

[0047] Please refer to Figures 5-6. The ultraviolet disinfection assembly 9 includes a mounting frame 91, a first arc-shaped plate 92, a first ultraviolet lamp 93, a fourth gear 94, a second arc-shaped plate 95, and a second ultraviolet lamp 96. Two mounting frames 91 are provided, and the two mounting frames 91 are fixedly installed on the bottom of the disinfection box 1. The first arc-shaped plate 92 is fixedly installed between the two mounting frames 91. The first ultraviolet lamp 93 is evenly installed on the upper side wall of the first arc-shaped plate 92. The fourth gear 94 is rotatably installed on the upper end of the mounting frame 91. The fourth gear 94 meshes with the second gear 93. The second arc-shaped plate 95 is fixedly installed on the fourth gear 94. The second ultraviolet lamp 96 is evenly installed on the inner side of the second arc-shaped plate 95. The first ultraviolet lamp 96 is located on the first arc-shaped plate 92. An ultraviolet lamp 93 can disinfect the lower side of the ultrasonic probe with ultraviolet light. When the ultrasonic probe moves downward with the fixed placement component 2, the second gear 63 on the gear assembly 6 can drive the fourth gear 94 to rotate, and the two second arc plates 95 can rotate towards the center. When the fixed placement component 2 stops moving, the two second arc plates 95 also stop rotating, and the second ultraviolet lamps 96 on the two second arc plates 95 can disinfect the upper side of the ultrasonic probe with ultraviolet light. Since the first arc plate 92 and the second arc plate 95 are both arc-shaped, the first ultraviolet lamp 93 and the second ultraviolet lamp 96 can also irradiate the left and right sides of the ultrasonic probe, so that the ultrasonic probe can be disinfected from all angles.

[0048] In this embodiment, by setting up the drive component 5 and the gear component 6, the ultraviolet disinfection component 9 can automatically rotate to a suitable position during the downward movement of the ultrasonic probe, so that the ultraviolet lamp can irradiate all parts of the ultrasonic probe, thereby achieving the purpose of thoroughly disinfecting the ultrasonic probe.

[0049] Please refer to Figures 3 and 7. The coupling agent heating assembly 8 includes an outer shell 81, an inner cylinder 82, a piston 83, and a pull rod 84. An installation rod 88 is fixedly connected to the upper end of the outer shell 81 and is fixedly connected to the upper wall of the disinfection box 1. A coupling agent storage tank 4 is installed on the top of the disinfection box 1. The inner cylinder 82 is coaxially installed inside the outer shell 81. An electric heating wire 85 is installed in the cavity between the inner cylinder 82 and the outer shell 81. The piston 83 is movably installed inside the inner cylinder 82. A pull rod 84 is connected to the upper side of the piston 83. The upper end of the pull rod 84 passes through the outer shell 81 and is connected to the extrusion assembly 7. An extrusion nozzle 86 is connected to the center of the bottom of the outer shell 81. A feed pipe 87 connected to the inner cylinder 82 is also installed at the bottom of the outer shell 81. The end of the feed pipe 87 extends out of the disinfection box 1 and is connected to the coupling agent storage tank 4. A one-way valve is installed at the interface of the extrusion nozzle 86 and the feed pipe 87.

[0050] The extrusion assembly 7 includes an L-shaped plate 71, a horizontal plate 72, and a second rack 73. The upper end of the L-shaped plate 71 is fixedly connected to the upper end of the pull rod 84, and the lower end of the L-shaped plate 71 is connected to the horizontal plate 72. The two ends of the horizontal plate 72 are respectively connected to the second rack 73, and the second rack 73 is meshed with the third gear 64.

[0051] The third gear 64 on the gear assembly 6 can drive the second rack 73 to move up and down. During the movement of the second rack 73, the pull rod 84 can pull the piston 83 to move up and down. When the piston 83 moves upward, the coupling agent in the coupling agent storage tank 4 can enter the inner cylinder 82 through the feed pipe 87. When the electric heating wire 85 is energized, it can heat the coupling agent inside the inner cylinder 82, causing the coupling agent temperature to rise. When the piston 83 moves downward, the piston 83 can squeeze out the coupling agent in the inner cylinder 82. The coupling agent is squeezed onto the ultrasonic probe through the extrusion nozzle 86.

[0052] In this embodiment, when the ultrasound probe is moved down for disinfection, the extrusion assembly 7 is driven by the gear assembly 6 to store the coupling agent on the coupling agent heating assembly 8. The coupling agent heating assembly 8 can heat the coupling agent in the inner cylinder 82, so that the extruded coupling agent has a certain temperature, avoiding the coupling agent being too cold and causing discomfort to the patient when it comes into contact with the patient's skin. When the ultrasound probe is disinfected and needs to be taken out for use, the gear assembly 6 drives the extrusion assembly 7 to move downward, and the heated coupling agent can be automatically extruded and fall onto the ultrasound probe. The doctor can then directly take out the ultrasound probe for use.

[0053] Specifically, the working principle of this automatic disinfection device for ultrasound probes is as follows: When the ultrasound probe needs disinfection after wiping away the coupling agent, the ultrasound probe is placed on the fixed placement piece 2. The handle of the ultrasound probe squeezes the locking block 23 to move it to both sides. After the ultrasound probe is placed, the two locking blocks 23 come closer together again, thus fixing the ultrasound probe on the fixed placement piece 2. Then, the handle on the front side of the fixed placement piece 2 is grasped and moved downwards. When the fixed placement piece 2 moves to its lowest position, the trapezoidal block 27 can be locked into the locking slot 34. At this time, the fixed placement piece 2 can be stably placed at the lowest point of the T-shaped mounting opening 11. During the downward movement of the fixed placement piece 2, the second gear on the gear assembly 6... The third gear 63 can drive the fourth gear 94 to rotate, and the two second arc plates 95 can rotate towards the center. When the fixed placement part 2 stops moving, the two second arc plates 95 also stop rotating. The second ultraviolet lamps 96 on the two second arc plates 95 can then perform ultraviolet disinfection on the upper side of the ultrasonic probe. The third gear 64 can drive the second rack 73 to move up and down. During the movement of the second rack 73, the pull rod 84 can pull the piston 83 to move up and down. When the piston 83 moves upward, the coupling agent in the coupling agent storage tank 4 can enter the inner cylinder 82 through the feed pipe 87. When the electric heating wire 85 is energized, it can heat the coupling agent inside the inner cylinder 82, causing the coupling agent temperature to rise.

[0054] When the ultrasonic probe is sterilized and needs to be removed for use, manually move the lever 28 to move the slider 26 into the groove 25. The trapezoidal block 27 can then be pulled out from the slot 34, pushing the fixed placement piece 2 upward. At this time, the gear assembly 6 rotates in the opposite direction, and the second arc plate 95 rotates to both sides. The extrusion assembly 7 drives the piston 83 to move downward, and the piston 83 can then squeeze out the coupling agent in the inner cylinder 82. The coupling agent is squeezed onto the ultrasonic probe through the extrusion nozzle 86, so that the heated coupling agent can be automatically applied to the probe during the ultrasonic probe removal process.

[0055] It should be noted that the specific model and specifications of the first ultraviolet lamp 93 and the second ultraviolet lamp 96 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0056] The power supply and operating principle of the first ultraviolet lamp 93 and the second ultraviolet lamp 96 are clear to those skilled in the art and will not be described in detail here.
