Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasonic portable self-cleaning disinfection box. Background Technology

[0002] Ultrasound examination utilizes the reflection of ultrasound waves from the limbs for observation. Weak ultrasound waves are shone onto the limb, and the reflected waves from the tissue are imaged. Ultrasound examination is also used in conjunction with other examination methods, such as ultrasound-guided biopsies for histological examination under ultrasound monitoring. In many scenarios, including medical, veterinary, and scientific research testing, ultrasound equipment, especially ultrasound probes, frequently comes into contact with the human or animal body surface or various samples, making them highly susceptible to contamination by pathogens such as bacteria, viruses, and fungi, posing a high risk of cross-infection. Therefore, it is necessary to clean and disinfect ultrasound probes.

[0003] Traditional disinfection methods include chemical immersion disinfection, high-temperature and high-pressure sterilization, and ultraviolet disinfection lamps. Chemical immersion disinfection is time-consuming, requires frequent preparation of chemical reagents, and some reagent residues may corrode the probe. High-temperature and high-pressure sterilization is not suitable for ultrasound equipment with internal precision electronic components. Ordinary intensity ultraviolet lamp disinfection takes too long and is not conducive to clinical use. High intensity ultraviolet lamps have strong penetrating power and pose a greater hazard to surrounding personnel. Utility Model Content

[0028] In this embodiment, preferably, a disinfection and cleaning component 4 is also included. The disinfection and cleaning component 4 is disposed at the top of the disinfection chamber 11 and is used to spray disinfectant solution onto the disinfection instruments in the disinfection chamber 11. The cleaning and disinfection component is installed on the side wall at the top of the disinfection chamber 11, and the lower end of the cleaning and disinfection component is connected to the liquid storage component 31. The disinfection and cleaning component 4 includes multiple nozzles 41, which are arranged sequentially at intervals along the length direction of the disinfection and cleaning component 4. A micro pump can also be provided in the storage chamber 3. The micro pump can transport the cleaning solution in the liquid storage component 31 to the disinfection and cleaning component 4 and spray it out from each nozzle 41 to achieve cleaning and disinfection of the ultrasonic probe 5 and the supporting instruments.

[0029] In this embodiment, preferably, a disinfection pool 15 is provided inside the disinfection chamber 11, a disinfection mounting frame 12 is disposed inside the disinfection pool 15, and a drain outlet 13 is disposed on one side of the disinfection pool 15. The placement frame 2 includes a bottom frame 21 and a top frame 22. The probe placement area 23 is disposed on the bottom frame 21, and the instrument placement area is disposed on the top frame 22. Both the bottom frame 21 and the top frame 22 have hollowed-out portions at their bottoms. A connecting post is provided at the bottom of the bottom frame 21, and a connecting hole for inserting the connecting post is provided on the disinfection mounting frame 12. Multiple connecting posts and connecting holes are provided, so that during use, the connecting posts can be inserted one by one into the corresponding connecting holes, thereby fixing the bottom frame 21 to the disinfection mounting frame 12. The connecting posts and connecting holes adopt a clearance fit, with the clearance controlled at 0.1-0.3 mm, which facilitates installation and ensures a certain positioning accuracy, making the bottom frame 21 stable and not easy to shake. After installation, the levelness of the bottom frame 21 is checked, and any deviation can be corrected by fine-tuning the position of the connecting posts.

[0030] Inside the box 1, there is also a conveying device for transporting disinfectant. The conveying device can be a conveying pump and a conveying pipe. The conveying device can transport the disinfectant in the storage container to the disinfection pool 15. When cleaning and disinfecting by the miniature ultrasonic generator, the disinfectant in the disinfection pool 15 exceeds the bottom shelf 21, so that the ultrasonic probe 5 is immersed in the disinfectant. The top disinfection shelf can be immersed in the disinfectant or not, which can be set as needed.

[0031] In this embodiment, preferably, the top shelf 22 is provided with a placement grid for placing instruments. There are multiple placement grids, which are spaced apart on the top shelf 22. The hollow part includes a drain hole at the bottom of the placement grid, which facilitates the flow of cleaning fluid to the bottom shelf 21.

[0032] In this embodiment, preferably, the probe placement area 23 includes a placement pad 24 disposed on the bottom frame 21. The placement pad 24 is provided with a placement groove 25 for placing the ultrasonic probe 5. Restriction adjustment members 26 are provided on opposite sides of the placement groove 25. The restriction adjustment members 26 include a restriction plate 261 and an adjustment screw 262 disposed on the restriction plate 261. A rotating operating head 263 is provided at the end of the adjustment screw 262 away from the restriction plate 261. The rotating operating head 263 can drive the adjustment screw 262 to rotate, thereby adjusting the position of the restriction plate 261. When the restriction plates 261 are adjusted to move closer to each other, the two restriction plates 261 can clamp and fix the ultrasonic probe 5 from opposite sides. Conversely, when the restriction plates 261 are adjusted to move apart from each other, the distance between the restriction plates 261 increases, and the clamping of the ultrasonic probe 5 can be loosened, making it easier to pick up or place the ultrasonic probe 5.

[0033] In this embodiment, preferably, both sides of the placement groove 25 are provided with a moving opening groove 27 and an adjusting opening groove 28, and a connecting part is formed between the moving opening groove 27 and the adjusting opening groove 28. A spiral channel is provided in the connecting part. The limiting piece 261 is slidably connected in the moving opening groove 27, and the end of the adjusting screw 262 is rotatably connected to the limiting piece 261. That is, the rotation of the adjusting screw 262 drives the limiting piece 261 to reciprocate in the moving opening groove 27. The adjusting screw 262 is rotatably installed in the spiral channel, and the rotating operating head 263 is located in the adjusting opening groove 28. In use, the operator rotates the operating head, and the adjusting screw 262 rotates in the spiral channel, thereby driving the limiting piece 261 to move along the moving opening groove 27, thereby clamping or releasing the ultrasonic probe 5.

[0034] An ultraviolet (UV) lamp can be installed at the top of storage chamber 3. The UV lamp uses a highly efficient sterilization wavelength of 253.7nm, directly destroying the DNA or RNA of microorganisms. UV irradiation causes some oxygen in the air inside the chamber to be converted into ozone. Ozone has extremely strong oxidizing properties and can penetrate into instrument gaps and dead corners, further oxidizing and killing bacteria and viruses. After disinfection, an activated carbon filter adsorbs residual ozone, ensuring safe use. A UV intensity sensor and an automatic shut-off device are installed on the chamber 1. When the lid 1 is opened, the automatic shut-off device immediately cuts off the power to the UV lamp to prevent UV leakage from harming operators. During disinfection, the UV intensity sensor monitors the lamp's output intensity in real time. When the intensity falls below a set effective threshold (e.g., 70% of the initial intensity), an alarm is triggered to prompt lamp replacement, ensuring both disinfection effectiveness and personnel safety.

[0035] In this embodiment, the installation steps during use are as follows:

[0036] The first step is to install a liquid storage component 31 and a waste liquid storage component 32 in the storage chamber 3. The liquid storage component 31 and the waste liquid storage component 32 are fixed by means of slots, brackets or bolts, etc., to ensure that the installation position of the liquid storage component 31 is lower than the interface of the infusion component 33, so as to facilitate the gravity flow of liquid. The waste liquid storage component 32 is installed below the outlet of the drain component 14 to ensure that the waste liquid can flow smoothly into the collection, and both are well sealed to prevent liquid leakage from contaminating the internal environment of the disinfection box.

[0037] The second step is to fix the bottom frame 21 onto the disinfection mounting frame 12. The connecting posts and connecting holes are fitted with a clearance fit, with the clearance controlled between 0.1 and 0.3 mm. This facilitates installation and ensures a certain level of positioning accuracy, allowing the bottom frame 21 to be placed stably and without wobbling. After installation, check the levelness of the bottom frame 21. If there is any deviation, it can be corrected by fine-tuning the position of the connecting posts.

[0038] The third step is to install the miniature ultrasonic generator on the pre-set mounting base on the side wall of the disinfection chamber 11. Use shock-absorbing pads or flexible connection structures to reduce vibration transmission during operation and ensure safe and reliable electrical connections. Connect and debug the wiring according to the equipment instruction manual. Install the disinfection and cleaning component 4 on the pre-set mounting position at the top of the disinfection chamber 11 and connect it to the infusion pipe of the liquid storage component 31, ensuring that the nozzle direction covers the entire effective area of ​​the disinfection chamber 11 and that the pipe connections are tight and leak-free.

[0039] In this embodiment, the operation steps during use are as follows:

[0040] First, open the top cover 16 of the box 1, carefully place the ultrasonic probe 5 that needs to be cleaned and disinfected into the placement slot 25 of the bottom shelf 21, and fix the ultrasonic probe 5 with the limiting adjustment component 26 to ensure that the probe position is stable and fully contacts the disinfectant and ultrasonic action area during the disinfection process. Set the instrument placement area that needs to be cleaned and disinfected on the top shelf 22 to ensure that the instruments are placed stably and do not block each other, so as not to affect the disinfection effect.

[0041] The second step involves closing the cover 16 and activating the infusion unit 33. The infusion volume or liquid level is set according to the disinfection requirements, allowing the disinfectant to flow into the disinfection pool 15 to the predetermined level (e.g., 80%-120% of the height of the bottom shelf 21). The liquid level can be monitored via a level sensor or a transparent observation window. Then, the miniature ultrasonic generator is turned on, and the cleaning program is started. The operating frequency is set to 40-60kHz. The miniature ultrasonic generator utilizes the cavitation effect of ultrasound in the disinfectant to generate high-frequency ultrasound, causing the built-in disinfectant solution to vibrate violently, creating a cavitation effect. The tiny bubbles generated by cavitation burst instantly, releasing enormous energy that impacts the microorganisms on the probe and instrument surface, shattering their cell membranes and cell walls, thus achieving sterilization. Simultaneously, the high-speed micro-jet generated by the bursting bubbles can remove impurities adhering to the instrument surface. The frequency and operating time are adjusted appropriately according to the degree of contamination and material of the ultrasonic probe and instruments (generally 10-30 minutes).

[0042] Third, after disinfection by the miniature ultrasonic generator, the disinfectant in the disinfection tank 15 is discharged into the waste liquid storage container 32. During the drainage process, observe whether the drainage is smooth. If there is a blockage, check the drain outlet and pipes for foreign objects or air bubbles, and clean and unclog them in time. After drainage, if further cleaning is required, start the miniature pump in the storage chamber 3 to deliver the cleaning solution in the storage container 31 to the disinfection and cleaning container 4. Spray the solution evenly onto the ultrasonic probe and instrument surface through the nozzle 41. The cleaning time is 5-15 minutes. After cleaning, the waste liquid is also discharged into the waste liquid storage container 32.

[0043] Fourth, after the operation is completed, open the cover 16, loosen the limiting adjustment piece 26, take out the disinfected and cleaned ultrasonic probe 5 and instruments, clean the residual liquid and impurities inside the box 1, and keep the box 1 clean and dry to prepare for the next use. The components of the box 1 can be inspected and maintained periodically.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
