Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to an ultrasonic probe cleaning device. Background Art

[0002] During the ultrasound diagnosis process, the ultrasound probe is a key device, and its surface often has residual ultrasound coupling agent, and may be attached with impurities such as stains and body fluids. These residues not only affect the imaging quality of the probe, but may also become a risk source of cross-infection, posing a potential threat to the health of doctors and patients. Therefore, it is particularly important to clean and disinfect the ultrasound probe in a timely and effective manner after each use. In addition, the ultrasound probe has poor waterproof performance and cannot be directly cleaned with liquid.

[0003] In the prior art, the cleaning and disinfection process of ultrasound probes is generally simple and has many shortcomings. Usually, medical staff will first wipe the surface of the probe with a paper towel to remove residual coupling agent and some stains. However, the cleaning ability of paper towels is limited, and it is often impossible to completely remove all impurities on the surface of the probe, especially stains and body fluids in tiny gaps or depressions. Medical staff will use alcohol to disinfect the probe. Although alcohol has a certain bactericidal effect, its disinfection efficiency is not high, and it takes a long time to achieve the ideal disinfection effect. In addition, long-term repeated use of alcohol to wipe the probe may also cause damage to the material of the probe surface, affecting its service life and imaging quality.

[0004] The above traditional cleaning and disinfection methods are not only inefficient, affecting the progress of ultrasonic diagnosis, but also incomplete in disinfection, making it difficult to ensure that the probe surface is thoroughly clean and sterile. Especially in medical institutions such as hospitals, ultrasonic diagnostic equipment is used frequently, and there are higher requirements for the efficiency and effect of cleaning and disinfection. Therefore, the development of a new technology that can efficiently and thoroughly clean and disinfect ultrasonic probes has become an urgent problem to be solved in the current field of ultrasonic diagnosis.

[0051] See also Figures 1 to 5 This embodiment provides an ultrasonic probe cleaning device 2. The ultrasonic probe cleaning device 2 can be used to clean the coupling agent on the surface of the ultrasonic probe 1 and disinfect it, so as to remove the coupling agent (i.e., ultrasonic coupling agent) adhering to the surface during use, and at the same time disinfect the surface of the ultrasonic probe 1 to improve the cleaning efficiency of the ultrasonic probe 1 during use.

[0052] like Figure 1As shown, in this embodiment, the ultrasonic probe cleaning device 2 includes a shell 20 and an internal device arranged inside the shell 20. A cleaning inlet 201 is arranged at the top of the shell 20, and the ultrasonic probe 1 can be inserted through the cleaning inlet 201, and then the internal device is cleaned. The shell 20 can be made of metal or alloy such as iron, aluminum, aluminum alloy, etc., and the shell 20 can also be made of plastic such as PV. The shape of the cleaning inlet 201 can be elliptical, and its size is slightly larger than the size of the top of the ultrasonic probe 1, so that the ultrasonic probe 1 can be easily inserted into the shell 20.

[0053] like Figure 2 As shown, the ultrasonic probe cleaning device 2 includes: a cleaning belt 21, a scraper 27, a container 23 and a water pressure control roller.

[0054] like Figure 3 As shown, the cleaning belt 21 is annular, and a plurality of flexible scraping strips 211 are arranged at intervals on the surface of the cleaning belt 21 along the running direction, and a water-absorbing cotton 212 is arranged between two adjacent flexible scraping strips 211. Figure 5 As shown, the cleaning belt 21 includes a base belt 213, which can be a flexible rubber belt. A flexible scraper strip 211 is arranged on the base belt 213 at equal intervals (for example, every 5-8 cm). The flexible scraper strip 211 protrudes from the surface of the base belt 213 in the thickness direction, and the absorbent cotton 212 can be fixed to the surface of the base belt 213 by gluing or the like, wherein the height of the flexible scraper strip 211 on the surface of the cleaning belt 21 is higher than the absorbent cotton 212.

[0055] The cleaning belt 21 is installed on a plurality of guide wheels 22 and is tensioned and driven by the guide wheels 22 to circulate. The front end of the ultrasonic probe 1 contacts the surface of the cleaning belt 21. The flexible scraper 211 is used to scrape off the coupling agent on the surface of the ultrasonic probe 1. The absorbent cotton 212 absorbs disinfectant to disinfect the surface of the ultrasonic probe 1.

[0056] The scraper 27 is disposed on the side of the cleaning belt 21 that is transported away from the ultrasonic probe 1. The scraper 27 is in contact with the surface of the cleaning belt 21 and is used to scrape off the coupling agent on the surface of the cleaning belt 21. Figure 2 As shown, the cleaning belt 21 runs counterclockwise, and the scraper 27 is set at Figure 2 Therefore, most of the coupling agent scraped from the ultrasonic probe 1 is scraped off by the scraper 27 before entering the container 23.

[0057] The container 23 is arranged at the bottom of the cleaning belt 21, and the container 23 is filled with disinfectant; the bottom of the cleaning belt 21 is immersed in the disinfectant to provide disinfectant for the absorbent cotton 212. The disinfectant can be 75% alcohol or other similar disinfectants.

[0058] A water pressure control roller is arranged above the container 23, and the water pressure control roller is located on the side where the cleaning belt 21 runs away from the container 23. Figure 2 As shown, the water control pressure roller is arranged above the right side of the container 23. The water control pressure roller includes a first pressure roller and a second pressure roller arranged opposite to each other, and the first pressure roller and the second pressure roller are driven by a pressure device to clamp the cleaning belt 21 to prevent excessive disinfectant on the cleaning belt 21. The first pressure roller and the second pressure roller are both arranged on corresponding rotating bearings, and the rotating bearings are sleeved on the mounting rod so that the first pressure roller and the second pressure roller can rotate freely. When controlling water, the first pressure roller and the second pressure roller rotate with the operation of the cleaning belt, so that the excess disinfectant in the absorbent cotton 212 can be effectively squeezed out, and the friction resistance with the cleaning belt 21 can also be reduced.

[0059] The water control pressure roller is arranged above the container 23 and located on the side where the cleaning belt 21 runs away from the container 23. The water control pressure roller includes a first pressure roller and a second pressure roller which are arranged oppositely on the front and back sides of the cleaning belt 21. The first pressure roller and the second pressure roller are driven by a pressure device to clamp the cleaning belt 21 to prevent excessive disinfectant on the cleaning belt 21.

[0060] During cleaning, the ultrasonic probe 1 is moved along Figure 2 The cleaning belt 201 is inserted into the vertical direction indicated by the middle arrow H, and contacts the surface of the cleaning belt 21; the cleaning belt 21 is driven by the guide wheel 22, and the surface of the ultrasonic probe 1 contacts the cleaning belt 21. The flexible scraper 211 can scrape off the coupling agent on the ultrasonic probe 1, and the disinfectant in the absorbent cotton 212 on the cleaning belt 21 can disinfect the ultrasonic probe 1. The flexible scraper 211 and the absorbent cotton 212 can clean and disinfect the ultrasonic probe 1 at the same time, thereby improving the cleaning efficiency of the ultrasonic probe 1. In addition, in the present embodiment, the coupling agent on the cleaning belt 21 is scraped off the cleaning belt 21 by the scraper plate 27, and the cleaning belt 21 can circulate and replenish the disinfectant from the container 23, that is, the cleaning belt 21 can self-clean while cleaning the ultrasonic probe 1, so that the cleaning belt 21 maintains good cleaning performance, and the cleaning belt 21 can circulate for a long time, reducing its maintenance frequency.

[0061] like Figure 3 As shown, among the plurality of guide wheels 22, at least one guide wheel 22 is a driving wheel, and at least one guide wheel 22 is a tensioning wheel for elastically tensioning the cleaning belt 21 outward. The driving wheel is connected to a driving motor and is driven to rotate by the driving motor, and the driving wheel drives the cleaning belt 21 to circulate in the same direction. Figure 3As shown, in this embodiment, the guide wheel 22 includes two top wheels 221 at the top, two bottom wheels 223 at the bottom, and two tensioning wheels 222 at the middle; the support base 26 is located between the two top wheels 221. The tensioning wheel 222 is arranged at the end of the swing arm, the top of the swing arm is hinged, and the swing arm is connected with a spring so that the swing arm brings the tensioning wheel 222 to tension the cleaning belt 21 outward, as shown in FIG. Figure 3 As shown, in this embodiment, the tensioning wheel 222 tensions the cleaning belt 21 to the left and right sides.

[0062] like Figure 2 As shown, the ultrasonic probe cleaning device 2 further includes: a supporting base 26 .

[0063] The support base 26 is arranged on the back of the cleaning belt 21 and opposite to the position of the ultrasonic probe 1, and is used to elastically support the ultrasonic probe 1. The bottom of the support base 26 is provided with a support spring 261 and a travel switch;

[0064] The travel switch is used to detect the downward movement distance of the support base 26, and is set to be triggered after the ultrasonic probe 1 contacts the cleaning belt 21 and moves downward a preset distance, so as to control the start of the transportation of the cleaning belt 21; the support base 26 is provided with forks 25 on both sides of the running direction of the cleaning belt 21; the forks 25 are against the two sides of the width direction of the cleaning belt 21, and are used to control the cleaning belt 21 to swing along the transverse width direction when the cleaning belt 21 is transported, so as to increase the contact range between the cleaning belt 21 and the ultrasonic probe 1, and the width direction is perpendicular to the running direction. The width direction of the cleaning belt 21 is Figure 2 The direction indicated by the arrow W. Figure 4 As shown, the shift fork 25 includes a first shift rod 251 disposed on one side of the width direction of the cleaning belt 21 and a second shift rod 252 disposed on the other side of the width direction of the cleaning belt 21 opposite to the first shift rod 251. The bottoms of the first shift rod 251 and the second shift rod 252 are connected and connected to the support base 26 through a connecting rod 235. The support base 26 is driven by a swing arm to reciprocate through a slide groove 262 (one end of the swing arm is connected to a rotating cam, and the other end is connected to a slider under the support base). The slide groove 262 extends along the width direction of the cleaning belt 21, wherein both ends of the slide groove can be fixed on the inner wall of the housing. In other embodiments, the support base 26 can also be driven by other reciprocating drive devices such as cylinders and linear motors to reciprocate along the width direction.

[0065] In this embodiment, the support base 26 is movably disposed on the slide groove 262 by the slider 263, so that the fork 25 can be driven to move along the width direction (ie Figure 2The cleaning belt 21 swings in the direction indicated by the arrow W in the middle (the direction indicated by the arrow W in the middle), and the cleaning belt 21 swings in the width direction driven by the shift fork 25. Therefore, when the cleaning belt 21 is running, the cleaning belt 21 not only runs in the length direction (i.e. Figure 2 It rotates in the counterclockwise direction in the rotation direction) and swings in the width direction perpendicular to the rotation direction. Figure 1 , Figure 2 and Figure 4 As shown, when the ultrasonic probe is inserted into the cleaning inlet, the width direction of the ultrasonic probe is consistent with the length direction (i.e., the running direction) of the cleaning belt 21. Since the cleaning belt can be driven by the shift fork to swing back and forth along the thickness direction of the cleaning belt, the contact range between the cleaning belt 21 and the ultrasonic probe 1 is greatly increased, and the coupling agent on the peripheral side of the thickness direction of the ultrasonic probe 1 can be effectively cleaned. In this embodiment, the travel switch can be a micro switch, a photoelectric sensor, or a Hall sensor; the bottom of the support base 26 is arranged on the slider 263 through the support spring 261, and a guide rod 264 can be arranged inside the support spring 261. The top of the slider 263 is provided with an avoidance hole 265 adapted to the guide rod 264, and the travel switch can be arranged on the inner side wall of the avoidance hole 265 or on the top of the slider 263. The travel switch can be connected in series to the power supply circuit of the drive motor of the guide wheel 22. When the travel switch detects that the support base 26 moves down to a preset distance (e.g., 3 cm), the travel switch is turned on, so that the power supply circuit of the drive motor is closed, and the drive motor starts to rotate.

[0066] In this embodiment, a support base 26, a support spring 261 and a travel switch are provided. When the operator inserts the ultrasonic probe 1 into the preset position, the cleaning belt 21 can automatically operate, thereby improving the operating efficiency of the ultrasonic probe cleaning device 2. Figure 2 As shown, the ultrasonic probe 1 presses down the cleaning belt 21 , so that the cleaning belt 21 forms a V-shape, thereby increasing the contact area between the cleaning belt 21 and the ultrasonic probe 1 .

[0067] like Figure 2 As shown, in this embodiment, the ultrasonic probe cleaning device 2 also includes: a glue cleaning brush 232, which is arranged at the bottom of the container 23, and the glue cleaning brush 232 is in contact with the surface of the cleaning belt 21, and is used to clean the coupling agent remaining on the surface of the cleaning belt 21.

[0068] The function is to further remove the coupling agent remaining on the surface of the cleaning belt 21 through the adhesive removal brush 232.

[0069] like Figure 2 As shown, in one embodiment, an ultrasonic oscillation generator 231 is further disposed at the bottom of the container 23 for generating ultrasonic waves to clean the cleaning belt 21 .

[0070] The high-frequency vibration signal generated by the ultrasonic oscillator 231 is converted into a high-frequency mechanical vibration wave through the transducer, and propagates to the disinfectant in the container 23 to form a cavitation effect, thereby achieving the purpose of cleaning the cleaning belt 21. The ultrasonic oscillator 231 can further remove the coupling agent and other stains attached to the cleaning belt 21.

[0071] like Figure 2 As shown, in this embodiment, the scraper plate 27 is arranged below the top wheel 221 on the side where the cleaning belt 21 is transported away from the ultrasonic probe 1, and the top end of the scraper plate 27 contacts the surface of the cleaning belt 21. The scraper plate 27 is inclined so that the coupling agent falls into the collection bag along the scraper plate 27.

[0072] The bottom end of the scraper plate 27 extends out of the outer shell 20, and the collecting bag can be hung outside the outer shell 20, so that the collecting bag can be easily replaced.

[0073] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
