Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasonic diagnosis, and particularly relates to an ultrasonic diagnosis device for auxiliary positioning. Background Art

[0002] An ultrasonic diagnosis device, also known as an ultrasonic diagnostic instrument, is based on the propagation characteristics of ultrasonic waves in human tissues. It emits high-frequency ultrasonic pulses through a probe. When these pulses propagate in human tissues, they will be reflected, refracted, and attenuated. When ultrasonic waves encounter different tissue interfaces, echo signals will be generated. The probe receives these echo signals and converts them into electrical signals. The signal processing system of the ultrasonic diagnostic instrument amplifies, processes, and analyzes these electrical signals, and generates two-dimensional or three-dimensional images of the internal structure of the human body according to information such as the intensity, propagation time, and position of the echo signals. By analyzing these images, doctors can observe the morphology, size, position of organs, as well as the internal structure and blood flow conditions of tissues, so as to diagnose and evaluate diseases. In the medical field, ultrasonic diagnostic instruments are widely used in clinical examinations.

[0003] Before use, the probe needs to be disinfected to ensure hygiene and safety. During operation, an appropriate amount of coupling agent is applied to the surface of the probe and the patient's skin to reduce air interference and enhance the penetration effect of ultrasonic waves. Then, the probe is gently placed on the patient's skin, and the angle and position of the probe are adjusted as needed to obtain the best imaging effect. After the examination, the probe is cleaned in time to remove the residual coupling agent, disinfected, and properly stored for the next use.

[0004] The probe directly contacts the patient's skin. Especially in the case of a large flow of people, it needs to be disinfected frequently to prevent cross-infection. In actual medical scenarios, the conventional disinfection steps of ultrasonic probes are cumbersome. Medical staff need to manually remove the coupling agent on the surface of the probe first, then wipe and disinfect it with a disinfectant, and finally wait for natural drying or dry it with a sterile towel. This process takes a certain amount of time and effort. In the case of examining a large number of patients in a day, if standardized disinfection is carried out each time, it will not only significantly affect work efficiency, prolong the waiting time of patients, increase the workload of doctors, but also may lead to incomplete disinfection due to non-standard operation. Moreover, frequent manual wiping may damage the probe, affecting its service life and imaging quality.

[0005] The Chinese invention patent with the patent number CN2022100548256 discloses an ultrasonic probe cleaning and disinfection device. The device mainly consists of a box body, a spray cleaning device, a coupling agent automatic coating device, a cover plate and a probe cover. A cleaning and disinfection chamber and an isolation coating chamber are arranged in the box body. The cleaning and disinfection chamber is equipped with a spray cleaning device for spraying and rinsing the ultrasonic probe. The cleaning and disinfection chamber is connected to a hot air generating device outside the box body through a side wall hot air input channel to realize the drying function of the probe. The probe is dried by the hot air entering through the side wall hot air input channel. The heat is not concentrated, and the heat needs to fill the entire cleaning and disinfection chamber to effectively dry the probe, resulting in low cleaning efficiency. Summary of the Invention

[0006] The object of the present invention is to provide an ultrasonic diagnostic device with auxiliary positioning, which can improve the cleaning efficiency of the probe.

[0007] The ultrasonic diagnostic device with auxiliary positioning includes an ultrasonic diagnostic instrument body. The ultrasonic diagnostic instrument body includes a probe. A cleaning and disinfection device for cleaning the probe is arranged on one side of the ultrasonic diagnostic instrument body. The cleaning and disinfection device includes a cleaning tank with an upward opening and capable of moving up and down. A drying component and a cleaning and disinfection component are sequentially arranged in the cleaning tank from top to bottom. A clamping component for clamping the probe is arranged above the cleaning tank. The cleaning tank moves up, and the probe extends into the cleaning tank to reach the area corresponding to the cleaning and disinfection component. The cleaning and disinfection component cleans and disinfects the probe. The cleaning tank moves down, and the probe reaches the area corresponding to the drying component. The drying component dries the probe and the inside of the cleaning tank.

[0008] When the probe needs to be soaked and disinfected, an appropriate amount of disinfectant is placed in the cleaning tank. The cleaning tank is moved upward, the probe is inserted into the cleaning tank, and the probe is immersed downward into the disinfectant. After the soaking is completed, the cleaning tank is moved downward, and the probe reaches the cleaning area corresponding to the cleaning and disinfection assembly, and the cleaning and disinfection assembly rinses the probe; when there is no need for soaking disinfection and the probe is directly spray-cleaned and disinfected, the cleaning tank is moved upward, the probe is inserted into the cleaning tank, reaches the cleaning area corresponding to the cleaning and disinfection assembly, and the cleaning and disinfection assembly sprays the probe to complete cleaning and disinfection; during the process of the cleaning and disinfection assembly spraying and cleaning or disinfecting the probe, by moving the cleaning tank up and down and moving around the probe up and down, the cleaning and disinfection of the probe are more thorough and the efficiency is higher; after the cleaning and disinfection of the probe are completed, the cleaning tank is moved downward, and the probe reaches the drying area corresponding to the drying assembly, and the position of the gas sprayed by the drying assembly is aligned with the probe for centralized drying; the cleaning tank can move up and down, so as to adjust the up and down position of the probe in the cleaning tank. A small amount of disinfectant can achieve the disinfection soaking of the probe, which can save the usage amount of the disinfectant during soaking, save resources. By moving the cleaning tank up and down, the probe can also be adjusted to be located in the cleaning area and the drying area respectively, and the cleaning, disinfection and drying of the probe are centralized, improving the cleaning efficiency of the probe.

[0009] Further, the cleaning and disinfection assembly includes a cleaning ring with an upper and lower communicating annular structure. The inner diameter of the cleaning ring gradually decreases from top to bottom. A plurality of liquid outlets for spraying cleaning liquid and disinfectant are evenly spaced on the side wall of one side of the inner circle of the cleaning ring. The cleaning tank is moved upward, and the probe is inserted into the central area inside the cleaning ring. The cleaning liquid and disinfectant sprayed from the liquid outlets clean and disinfect the probe.

[0010] The cleaning liquid sprayed from the liquid outlet for spraying the cleaning liquid cleans the probe located in the central area of the cleaning ring, and the disinfectant sprayed from the liquid outlet for spraying the disinfectant disinfects the probe. It can be cleaned first and then disinfected, or disinfected first and then cleaned, or cleaned and disinfected simultaneously. Different cleaning and disinfection methods are selected according to the cleaning requirements; the cleaning ring is in the shape of a horn with an inner diameter gradually decreasing from top to bottom, ensuring that the obliquely sprayed cleaning liquid and disinfectant can comprehensively clean and disinfect the bottom area of the probe.

[0011] Further, the drying assembly includes a drying ring with an upper and lower communicating annular structure. A plurality of air outlets for blowing air are distributed on both the side wall of one side of the inner circle and the side wall of one side of the outer circle of the drying ring. The cleaning tank is moved downward, and the probe reaches the central area inside the drying ring. The air blown out from the air outlets dries the probe and the cleaning tank.

[0012] The cleaning tank moves downward, enabling the probe to reach the central area inside the drying ring, corresponding to the position of the gas blown out from one side of the inner circle of the drying ring. The gas blown out from the side wall on one side of the inner circle of the drying ring dries the probe after cleaning and disinfection, accelerating the drying speed of the probe. Meanwhile, the gas blown out from the side wall on one side of the outer circle of the drying ring dries other areas inside the cleaning tank, accelerating the drying speed inside the cleaning tank. By moving the cleaning tank up and down, the air outlet is aligned with the probe for centralized drying, which is more efficient than the existing technology where the heat is not concentrated during probe drying and the entire cleaning and disinfection chamber needs to be filled with heat to dry the probe.

[0013] Further, the clamping assembly includes elastic pads symmetrically arranged at left and right intervals for clamping the probe inward, and each elastic pad is connected with an elastic member. When the probe is placed between the two elastic pads, the elastic pads move outward against the elastic force of the elastic members, clamping the probe between the two elastic pads. After the probe is taken out, the two elastic pads move inward due to the elastic force of the elastic members.

[0014] When the probe is not placed, due to the elastic force of the elastic members, the left-right distance between the two elastic pads is the closest, and this distance is smaller than the distance between the left and right sides of the probe. After the probe is placed between the two elastic pads, the elastic pads are squeezed to the two sides, and the elastic pads move to the two sides against the elastic force of the elastic members. At the same time, the probe is clamped due to the inward elastic force of the elastic members. The elastic pads that can expand and contract in and out can adapt to the clamping of probes of different sizes.

[0015] Further, the elastic member includes a spring connected to the outside of the two elastic pads. When the probe is placed between the two elastic pads, the elastic pads move outward against the elastic force of the spring, clamping the probe between the two elastic pads. After the probe is taken out, the two elastic pads move inward due to the elastic force of the spring.

[0016] The spring can not only meet the force required for clamping but also adapt to probes of different sizes.

[0017] Further, the clamping assembly further includes a housing composed of an upper cover and a lower cover. A circular hole communicating up and down is provided at the center position of the housing. The elastic pads are independently located inside the circular hole. The spring is in an arc structure and is installed inside the housing. Each elastic pad is connected to the spring through a top block. One end of the top block is connected to the elastic pad, and the other end independently extends into the housing to be connected to the spring. When the probe is placed between the two elastic pads, the elastic pads drive the top blocks to move outward against the elastic force of the spring, clamping the probe between the two elastic pads. After the probe is taken out, the two elastic pads move inward due to the elastic force of the spring.

[0018] The housing composed of the upper cover and the lower cover can ensure that there is sufficient space for the internal spring to move during use. The spring with an arc structure fits the position of the circular hole at the center of the housing. The elastic force of the spring with an arc structure is directed towards the center of the arc, which can increase the stability of the elastic pad. The housing can not only increase the stability of the spring but also prevent liquid from splashing out of the tank mouth of the cleaning tank when the probe is being cleaned and disinfected.

[0019] Furthermore, the elastic pads are all of arc structure, and the arc center lines of the left and right elastic pads coincide. An elastic piece for clamping the probe inward is fixed on the inner side of each elastic pad. A notch for the probe to enter and exit is provided on the housing corresponding to the clamping area between the left and right elastic pieces.

[0020] The elastic piece not only facilitates fitting with the flat probe and provides more stable clamping, but also, due to the elastic force of the elastic piece, can closely fit probes of other shapes, with a wide clamping range. The notch allows the probe to be inserted laterally for clamping. Compared with the existing vertical insertion for clamping, it can prevent substances such as coupling agent on the probe from contacting the clamping component during clamping and prevent contamination.

[0021] Furthermore, a bracket is provided between the ultrasonic diagnostic instrument body and the cleaning tank. The clamping component is connected to the bracket through a connecting piece. Above the clamping area of the clamping component, a protective support component is installed on the bracket. The protective support component includes a telescopic support plate. One end of the support plate is hinged to the connecting piece, and a locking piece for limiting the swing of the support plate after swinging is installed on the connecting piece at the hinge. The other end of the support plate is a swinging end, and a limiting groove for limiting the cable on the probe is provided at this end. A limiting block is provided in the limiting groove.

[0022] The limiting groove can assist in positioning and guiding the cable during the probe cleaning process. The swinging and telescoping support plate can adjust the position of the limiting groove according to the clamping position of the probe, so that the limiting groove is located above the probe, and the probe is assisted in positioning by the position of the cable connected to the probe.

[0023] Furthermore, the inner diameters of both the drying ring and the cleaning ring are larger than the maximum distance between the probes and smaller than the maximum distance of the bottom surface of the lower cover. The drying ring can move up and down. A moving and resetting component for resetting the drying ring after it moves down is installed in the cleaning tank. The moving and resetting component includes a mounting block vertically fixed on the inner side wall of the cleaning tank. A sliding groove is vertically provided on the mounting block. A sliding block that is slidably engaged with the sliding groove is provided in the sliding groove. A telescopic member for resetting the sliding block after it slides down along the sliding groove is installed between the bottom of the sliding groove and the sliding block. The side of the sliding block facing the drying ring is fixed to the drying ring. When the cleaning tank rises, under the downward pressure of the clamping component, the sliding block slides down in the sliding groove; when the cleaning tank descends, the telescopic member automatically extends, the sliding block slides upward, and the drying ring rises to the initial state. A splash guard for preventing liquid splashing is fixed to the top of the upper cover.

[0024] The inner circle diameters of the drying ring and the cleaning ring are both larger than the maximum distance between the probes and smaller than the maximum distance from the bottom surface of the lower cover. When cleaning, disinfecting, and drying, they are close to the probes, and the effects of cleaning, disinfecting, and drying are good. Moreover, when spraying and cleaning and disinfecting the probes, the liquid sprayed towards the inside is not easily splashed out due to the shielding of the housing. The splash guard shields the housing formed by the upper cover and the lower cover except for the clamping area part, further preventing liquid from splashing out. When the cleaning tank rises, under the downward pressure of the clamping assembly on the drying ring, the sliding block slides in the chute of the mounting block, so that the probes can be as close as possible to the bottom of the cleaning tank, saving the amount of disinfectant when soaking and disinfecting the probes.

[0025] Furthermore, the cleaning tank is connected to a lifting mechanism for driving its lifting and lowering.

[0026] The lifting mechanism drives the cleaning tank to lift and lower, facilitating automatic control and saving labor.

[0027] Compared with the prior art, the present invention has the following beneficial effects: When the probes need to be soaked and disinfected, an appropriate amount of disinfectant is placed in the cleaning tank. The cleaning tank moves upward, the probes extend into the cleaning tank, and the probes are immersed downward into the disinfectant. After soaking, the cleaning tank moves downward, and the probes reach the cleaning area corresponding to the cleaning and disinfecting assembly, and the cleaning and disinfecting assembly flushes the probes; when directly spraying and cleaning and disinfecting the probes without soaking and disinfecting, the cleaning tank moves upward, the probes extend into the cleaning tank, reach the cleaning area corresponding to the cleaning and disinfecting assembly, and the cleaning and disinfecting assembly sprays the probes to complete cleaning and disinfecting; during the process of the cleaning and disinfecting assembly spraying and cleaning or disinfecting the probes, by moving the cleaning tank up and down and moving around the probes up and down, the cleaning and disinfection of the probes are more thorough and the efficiency is higher; after the cleaning and disinfection of the probes are completed, the cleaning tank moves downward, and the probes reach the drying area corresponding to the drying assembly, and the position of the gas sprayed by the drying assembly is aligned with the probes for centralized drying; the cleaning tank can move up and down, thereby adjusting the up and down positions of the probes in the cleaning tank. A small amount of disinfectant can achieve the disinfection and soaking of the probes, saving the usage amount of disinfectant during soaking, saving resources. By moving the cleaning tank up and down, the positions of the probes in the cleaning area and the drying area can also be adjusted, centrally cleaning, disinfecting, and drying the probes, improving the cleaning efficiency of the probes.

Detailed implementation manners

[0030] The present invention will be further described below with reference to the accompanying drawings through specific embodiments, but it is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention. Embodiment

[0031] The ultrasound diagnostic instrument body 1 refers to the ultrasound diagnostic instrument in the prior art, which is a medical imaging device based on the physical properties of ultrasonic waves. By emitting ultrasonic waves into human tissues, receiving and analyzing the reflected echo signals, real-time dynamic images are generated for non-invasive observation of the internal structure, functional status and pathological changes of the human body. It mainly includes a main unit and a probe 11. The probe 11 is used to emit and receive ultrasonic waves; the main unit is used to process the echo signals, generate images and adjust parameters, display dynamic images in real time, and perform image storage, playback and data transmission.

[0032] An ultrasound diagnostic device with auxiliary positioning described in this embodiment is implemented by the following scheme: As Figure 1 and Figure 5 shown, the mounting base 2 includes a column. Mounting plates are fixed at the top and middle positions of the column, and a base is fixed at the bottom. The ultrasound diagnostic instrument body 1 is mounted on the top mounting plate of the mounting base 2. On the front and back sides of its left half, placement racks 10 are installed for placing the probe 11. The placement rack 10 adopts the existing known technology, and specifically, reference can be made to the existing placement rack for the probe 11. A cleaning and disinfection device 3 is installed on the front side of the right half of the top mounting plate of the mounting base 2.

[0033] As Figure 2 shown, the cleaning and disinfection device 3 is composed of a bracket 12, a protective support assembly 13, a clamping assembly 14, a cleaning tank 15, a drying ring 16, a cleaning ring 17, a moving and resetting assembly 18, a valve 19, a lifting mechanism 20 and a connecting piece 21. The cleaning and disinfection device 3 is connected to the mounting base 2 through the bracket 12, specifically as Figure 6 shown. As Figure 4 shown, the clamping assembly 14 is fixed to the top of the bracket 12 as Figure 1 shown through a connecting piece 21 with a "7"-shaped structure and is located on the front side.

[0034] As Figure 8 shown, the clamping assembly 14 is used to clamp the probe 11; its structure is as Figure 2 and Figure 3 shown. The clamping assembly 14 is composed of an upper cover 14.1, a top block 14.2, an elastic pad 14.3, a spring 14.4, a lower cover 14.5, an elastic sheet 14.6, an adjusting block 14.7 and an adjusting bolt 14.8. The upper cover 14.1 and the lower cover 14.5 have the same structure, both are square structures, and the two together form a housing. The bottom of the vertical part of the connecting piece 21 is fixed to the top of the rear side wall of the housing.

[0035] A circular through hole, that is, a circular hole communicating up and down, is provided at the center of the housing, and a rectangular structure notch penetrating to the central through hole is opened on the front side for the probe 11 to enter and exit.

[0036] As Figure 2 and Figure 3As shown in the figure, an arc-shaped groove is provided at the top of the lower cover 14.5. The center line of the arc of this arc-shaped groove coincides with the hollow line of the circular through-hole at the center of the housing. The two ends of this arc-shaped groove are respectively located on both sides of the rectangular notch. A rectangular hole communicating with the inside and outside is provided on each of the left and right sides of the arc-shaped groove. An ejector block 14.2 is independently placed in each rectangular hole. The ejector block 14.2 is in an inverted "convex" shape, and both its left and right sides are arc-shaped designs. The center of the arc coincides with the center of the circular through-hole of the lower cover 14.5. The outer arc of the ejector block 14.2 faces the spring 14.4, and a groove is provided along the arc direction for the spring 14.4 to be snapped into this groove in this position section. The inner arc side of the ejector block 14.2 is fixed to the elastic pad 14.3.

[0037] As Figure 3 and Figure 7 shown, the upper cover 14.1 and the lower cover 14.5 are in an up-and-down symmetrical structure. The upper cover 14.1 and the lower cover 14.5 are buckled and fixed, and a counterbore penetrating through to the internal arc-shaped groove is provided on the front side of the housing formed by the two. As Figure 8 shown, springs 14.4 are placed in the arc-shaped grooves of both the upper cover 14.1 and the lower cover 14.5, and are located in the grooves of the ejector blocks 14.2. As Figure 3 shown, the two ends of the upper and lower springs 14.4 are respectively fixed to the rear side of the adjusting block 14.7. A threaded hole penetrating through the front and rear is provided at the center of the adjusting block 14.7, and the adjusting block 14.7 is respectively placed at both ends of the arc-shaped grooves of the upper cover 14.1 and the lower cover 14.5. The adjusting bolt 14.8 passes through the counterbore on the front side of the housing and is threadedly engaged with the threaded hole on the adjusting block 14.7.

[0038] As Figure 2 and Figure 3 shown, elastic pads 14.3 are installed on the inner sides of both ejector blocks 14.2. The elastic pads 14.3 are in an arc-shaped structure, and the center of the arc is consistent with the center of the arc of the ejector blocks 14.2. Installation grooves are provided at both the front and rear ends of the elastic pads 14.3. Elastic sheets 14.6 made of elastic materials are installed in the installation grooves. The front and rear ends of each elastic sheet 14.6 are respectively located in the front and rear installation grooves of the same elastic pad 14.3. As Figure 3 shown, the two elastic sheets 14.6 are symmetrical left and right, and are used to clamp the probe 11 in the middle. The elastic pads 14.3 are made of high-elasticity materials, which can provide uniform elastic support for the elastic sheets 14.6 during the clamping process, and at the same time adapt to probes of different diameters to ensure the stability and reliability of clamping. The elastic sheets 14.6 utilize their own elasticity and shape to better fit the surface of the probe 11 during the clamping process, further enhancing the firmness and accuracy of clamping.

[0039] In actual use, the spring 14.4 can also be a spring with an arc structure installed in one or two upper and lower sections in the left housing of the elastic pad 14.3 on the left side. This spring 14.4 is connected to the elastic pad 14.3 on the left side through the top block 14.2; a spring 14.4 with an arc structure is installed in one or two sections in the right housing of the elastic pad 14.3 on the right side, and this spring 14.4 is connected to the elastic pad 14.3 on the right side through the top block 14.2; the number of springs 14.4 distributed up and down is determined according to the magnitude of the elastic force required for clamping the probe 11 and the stability requirements. When the probe 11 is not inserted, the distance between the left and right elastic sheets 14.6 is less than the width of the probe 11.

[0040] As Figure 6 shown, the protective support assembly 13 is composed of a locking bolt 13.1, an adjustment disk 13.2, a support plate 13.3, a splash guard 13.4, a limit groove 13.5, and a limit block 13.6. As Figure 4 shown, the support plate 13.3 is a telescopic plate with a locking function, and its structure includes an outer frame, a telescopic plate, and a locking bolt. The outer frame is sleeved on the telescopic plate, and the bolt is in threaded fit with the threaded hole on the outer frame. When the bolt is tightened, its end can top against the telescopic plate to lock the telescopic plate. For the detailed structure of the support plate 13.3, reference can be made to the prior art support rod with a locking function.

[0041] The rear side of the support plate 13.3 is hinged to the connecting member 21. The front side of the support plate 13.3 is provided with an inverted "U"-shaped limit groove 13.5 as Figure 6 and Figure 7 shown. The left and right sides of the open end of the limit groove 13.5 are respectively fixed with two semi-cylindrical structures and elastic limit blocks 13.6. As Figure 6 shown, an arc-shaped waist-shaped adjustment disk 13.2 is fixed at the rear end of the support plate 13.3. The arc center of the adjustment disk 13.2 is concentric with the hinge point of the support plate 13.3 and the connecting member 21. An arc-shaped limit groove matching the structure of the adjustment disk 13.2 is provided on the left side wall of the connecting member 21 for the adjustment disk 13.2 to rotate. The adjustment disk 13.2 can also be directly rotatably installed on the side wall of the connecting member 21. A locking bolt 13.1 is installed on the adjustment disk 13.2. As a locking member, after the front end of the support plate 13.3 swings to an appropriate position, the locking bolt 13.1 is tightened to fix the position of the adjustment disk 13.2 in the limit groove, thereby locking the position of the support plate 13.3 after swinging. As Figure 6 shown, there are four splash guards 13.4 in total, and each is a 1 / 4 semi-circular frame structure. A waterproof mesh cloth is installed inside each 1 / 4 semi-circular frame, and a transparent plate can also be selected. The splash guards 13.4 are grouped in pairs of two, as Figure 2As shown, they are respectively fixed on the outer sides of the top clamping areas of the elastic pieces 14.6. This design can not only effectively prevent liquid splashing, protect the device and the surrounding environment, but also flexibly adjust the position of the splash guard 13.4 according to the deformation of the elastic pieces 14.6, improving the adaptability of use.

[0042] As Figure 4 shown, the cleaning tank 15 is installed on the front side of the bracket 12 by the lifting mechanism 20. The lifting mechanism 20 is a prior art, and a linear motor or an electric screw rod lifting mechanism etc. can be selected. If a linear motor is adopted, the linear guide rail of the linear motor needs to be vertically and fixedly installed on the front side wall of the bracket 12 and located below the connecting piece 21. At the same time, the sliding block of the linear motor is fixedly connected to the rear side wall of the cleaning tank 15, and the sliding block drives the cleaning tank 15 to move up and down along the linear guide rail. If an electric screw rod lifting mechanism is adopted, the slider of the screw rod lifter is driven by the motor to move up and down. Its installation method is similar to that of the linear motor. The base is vertically and fixedly installed on the front side wall of the bracket 12 and located below the connecting piece 21. The slider is fixedly connected to the rear side wall of the cleaning tank 15. The motor drives the screw rod to rotate, so that the slider drives the cleaning tank 15 to move up and down along the screw rod on the base.

[0043] As Figure 2 shown, the cleaning tank 15 has a square tank body structure with an open top. The size of the clamping component 14 is slightly smaller than the opening size of the cleaning tank 15, which is convenient for the clamping component 14 to enter and exit the cleaning tank 15. A sewage outlet is provided at the center of the bottom of the cleaning tank 15 and is connected to a sewage pipe. A valve 19 is installed on the sewage pipe. The bottom inside of the cleaning tank 15 has a certain taper to the sewage outlet, and four through installation holes are provided on the right side. As Figure 2 and Figure 4 shown, the mouth of the cleaning tank 15 shrinks obliquely inward. As shown in 7, at the corresponding position of the front inner wall of the cleaning tank 15 and the notch of the rectangular structure of the housing, a baffle 22 with a size matching the notch of the rectangular structure of the housing is fixed.

[0044] As Figure 3 and Figure 9 shown, the moving and resetting component 18 is composed of an installation block 18.1, a telescopic member 18.2, a sliding block 18.3 and a fixing block 18.4. As Figure 3 and Figure 8 shown, the installation block 18.1 has a rectangular structure and is vertically fixed on the front and rear sides of the inner wall of the cleaning tank 15. An inverted "convex" - shaped chute is opened inside the installation block 18.1, and a fixing block 18.4 is fixed at the bottom of the chute. A sliding block 18.3 with a "convex" - shaped structure is arranged in the chute, and a through hole penetrating up and down is opened on it. An telescopic member 18.2 is assembled between the sliding block 18.3 and the fixing block 18.4. The telescopic member 18.2 is composed of a spring sleeved on a guide post. The bottom of the guide post is fixed on the top of the fixing block 18.4, and the top independently passes through the through hole of the sliding block 18.3.

[0045] As Figure 8 shown, a cleaning ring 17 is fixed between two fixed blocks 18.4. As Figure 6 and Figure 4 shown, the cleaning ring 17 has a horn-shaped structure with a larger upper part and a smaller lower part, and is internally provided with two independent chambers, namely a disinfection chamber 17.1 and a cleaning chamber 17.2. A number of liquid outlets 17.3 are evenly spaced on the inner circle of the cleaning ring 17, that is, a number of liquid outlets 17.3 for spraying cleaning liquid and disinfection liquid are evenly spaced on the side wall of the inner circle of the cleaning ring 17, and these liquid outlets 17.3 are respectively communicated with the disinfection chamber 17.1 and the cleaning chamber 17.2. The inner diameter of the cleaning ring 17 is in the shape of a horn that gradually becomes smaller from top to bottom, ensuring that the obliquely sprayed cleaning liquid and disinfection liquid can comprehensively clean and disinfect the bottom area of the probe 11.

[0046] Similarly as Figure 8 shown, a drying ring 16 is installed between two sliding blocks 18.3. The drying ring 16 is designed with a horn-shaped structure with a larger upper part and a smaller lower part, and a plurality of air ports are provided on both its inner and outer circles, that is, a number of air ports for blowing air are distributed on the side wall of the inner circle and the side wall of the outer circle of the drying ring 16.

[0047] As Figure 1 and Figure 5 shown, two water tanks 9 are installed on the mounting plate at the middle position of the mounting seat 2, one for filling distilled water or softened water or other cleaning liquids for cleaning the probe 11, and the other for filling disinfection liquid. The specific type of disinfection liquid can be determined according to actual use requirements. On the right side of the middle mounting plate of the mounting seat 2, an air pump 6 and two water pumps 7 are installed, and the liquid inlet of the water pump 7 is communicated with the water tank 9 through a pipeline.

[0048] As Figure 1 and Figure 2 shown, the liquid outlet of the water pump 7 is connected to the cleaning tank 15 through a water pipe 5. One end of the water pipe 5 is connected to the water pump 7, and the other end of the water pipe 5 passes through the mounting hole on the right side of the cleaning tank 15 and is respectively connected to and ensured to be communicated with the disinfection chamber 17.1 and the cleaning chamber 17.2. The air pump 6 is connected to the drying ring 16 through an air pipe 4. One end of the air pipe 4 is connected and communicated with the air outlet of the air pump 6, and the other end of the air pipe 4 passes through the cleaning tank 15 and is connected to and ensured to be communicated with the drying ring 16. To ensure the sealing performance of the cleaning tank 15, the connection parts of the water pipe 5 and the air pipe 4 with the cleaning tank 15 can be sealed with sealant or transferred using quick connectors.

[0049] The usage instructions of the above technical solution are as follows: When the model of the probe 11 is different and it is necessary to adjust the support position of the cable 8 using the protection and support component 13, the following operations are performed: As Figure 7As shown, according to the size of the probe 11, after loosening the locking bolt 13.1, swing the front end of the support plate 13.3 up and down and adjust the telescopic length of the support plate 13.3, so as to adjust the front and rear position and height of the limiting groove 13.5. Then tighten the locking bolt 13.1 to lock the adjusting disc 13.2 and prevent it from rotating, thereby locking the position of the support plate 13.3 to prevent swinging, and further realizing the position adjustment of the support plate 13.3 to make the limiting groove 13.5 in a suitable position.

[0050] When the clamping assembly 14 clamps the probe 11, the following operations are performed: As Figure 7 shown, drive the cleaning tank 15 to descend through the lifting mechanism 20, so that the clamping assembly 14 moves out of the cleaning tank 15 and reaches above the cleaning tank 15 to reserve enough space to avoid collision when clamping the probe 11. Place the probe 11 between the two elastic pieces 14.6 from the rectangular notch of the clamping assembly 14. The elastic pad 14.3 and the elastic piece 14.6 will clamp the probe 11 inward due to the elastic force of the spring 14.4. The cable 8 of the probe 11 is clamped in the limiting groove 13.5 to increase the bending radius of the cable 8, and the limiting block 13.6 prevents the cable 8 from falling out of the limiting groove 13.5; to avoid the situation that when the probe 11 is placed upside down, the outer skin of the cable 8 is easily broken under the condition of bending and twisting, which may lead to the breakage of the signal line and affect the normal use of the probe.

[0051] When using the cleaning ring 17 to clean and disinfect the probe 11, the following operations are performed: As Figure 8 shown, adjust the height of the cleaning tank 15 through the lifting mechanism 20 to make the probe 11 within the spraying range of the cleaning ring 17. Start the water pump 7, and sequentially transport the cleaning liquid and disinfectant in the water tank 9 to the disinfection chamber 17.1 and the cleaning chamber 17.2 of the cleaning ring 17 through the water pipe 5 and spray them out from the liquid outlet 17.3. First, rinse the coupling agent and the like on the probe 11, then spray the disinfectant for disinfection, and finally rinse the disinfectant with the cleaning liquid. Adjust the height of the cleaning tank 15 through the lifting mechanism 20 to make the probe 11 within the drying range of the drying ring 16 to improve the safety and efficiency of drying. Start the air pump 6, transport the compressed air to the drying ring 16 through the air pipe 4, and the air outlet holes on the inner ring of the drying ring 16 dry the probe 11, and the air outlet holes on the outer ring are used to dry the inside of the cleaning tank 15 and accelerate the discharge of the waste liquid. During the cleaning and disinfection process, the splash-proof plate 13.4 can effectively prevent liquid splashing and protect the equipment and the surrounding environment.

[0052] The cleaning liquid ejected from the liquid outlet 17.3 of the cleaning liquid cleans the probe 11 located in the central area of the cleaning ring 17, and the disinfectant liquid ejected from the liquid outlet 17.3 of the disinfectant liquid disinfects the probe 11. It can be cleaned first and then disinfected, or disinfected first and then cleaned, or cleaned and disinfected simultaneously; finally, the disinfectant liquid can be cleaned off; the cleaning ring 17 is in the shape of a horn with an inner circle diameter gradually decreasing from top to bottom, ensuring that the obliquely ejected cleaning liquid and disinfectant liquid can thoroughly clean and disinfect the bottom area of the probe 11; during the cleaning and disinfection process of the probe 11, the cleaning tank 15 can be moved up and down to drive the cleaning ring 17 to move up and down around the probe 11, making the cleaning and disinfection of the probe 11 more thorough.

[0053] During the cleaning and disinfection process of the probe 11, when it is necessary to soak and disinfect the probe 11, the following operations are carried out: As Figure 9 shown, the cleaning tank 15 is lifted by the lifting mechanism 20. Under the downward pressure of the clamping assembly 14 on the drying ring 16, the sliding block 18.3 slides downward in the chute of the mounting block 18.1, so that the probe 11 can move as close as possible to the inner bottom of the cleaning tank 15 but not touch the bottom of the cleaning tank 15. The water pump 7 is started, and the cleaning liquid and disinfectant liquid in the water tank 9 are respectively transported to the disinfection chamber 17.1 and the cleaning chamber 17.2 of the cleaning ring 17 through the water pipe 5 and ejected from the liquid outlet 17.3. First, the coupling agent on the probe 11 is rinsed, and then the disinfectant liquid is sprayed for disinfection; After the waste liquid in the cleaning tank 15 is discharged, the valve 19 is closed, and the water pump 7 controls the disinfectant liquid to enter the cleaning tank 15 until it covers the predetermined soaking depth of the probe 11. The specific soaking time and depth depend on the model and diagnostic type of the probe 11. The movable cleaning tank 15 up and down can extend the probe 11 to a position as close as possible to the inner bottom of the cleaning tank 15, with less consumption of disinfectant liquid and resource saving; After soaking is completed, the valve 19 is opened to discharge the waste liquid, and the cleaning liquid is used to rinse the disinfectant liquid attached to the probe 11. The height of the cleaning tank 15 is adjusted by the lifting mechanism 20 so that the probe 11 is within the drying range of the drying ring 16. The air pump 6 is started, and the drying gas below 50 degrees is transported to the drying ring 16 through the air pipe 4 and ejected from the air outlet. The air outlet on the inner circle of the drying ring 16 dries the probe 11, and the air outlet on the outer circle is used to dry the inside of the cleaning tank 15 and accelerate the discharge of the waste liquid.

[0054] The inner circle diameters of the drying ring 16 and the cleaning ring 17 are smaller than the diameter of the lower cover 14.5 and are close to the probe 11, resulting in good cleaning, disinfection, and drying effects. Moreover, when the probe 11 is spray-cleaned and disinfected, the liquid sprayed towards the inside is not easily splashed out due to the shielding of the housing. The splash-proof plates 13.4 fixed on the elastic sheets 14.6 on both sides of the clamping area shield the housing formed by the upper cover 14.1 and the lower cover 14.5 except for the clamping area part, further preventing liquid from splashing out.

[0055] During actual use, the start-stop time and start-stop sequence of the air pump 6, the water pump 7 for spraying cleaning liquid, the water pump 7 for spraying disinfectant liquid, the lifting mechanism 20, and the valve 19 can be controlled by the controller in the ultrasonic diagnostic apparatus main body 1, or a separate controller can be provided for centralized control and screen display. Medical staff only need to press a button to start and stop in the set mode to achieve the cleaning and disinfection of the probe 11, which is convenient and saves human resources.

[0056] The elastic pad 14.3 of the clamping assembly 14 can provide uniform elastic support for the elastic sheet 14.6 during the clamping process, and at the same time adapt to probes of different diameters, ensuring the stability and reliability of clamping. The elastic sheet 14.6 uses its own elasticity and shape to better fit the surface of the probe 11 during the clamping process, further enhancing the firmness and accuracy of clamping. The device can be applied to a variety of scenarios and probes 11 of different specifications, solving the problem of limited adaptability to probes of different sizes and shapes.

[0057] The height of the cleaning tank 15 is adjusted by the lifting mechanism 20 so that the probe 11 is within the drying range of the drying ring 16. Through the air ports on the inner and outer circles of the drying ring 16, the air pump 6 is used to provide drying gas to quickly and uniformly dry the probe 11, reducing the waiting time and improving work efficiency. It solves the problem in the prior art that the heat is not concentrated and the entire cleaning and disinfection chamber needs to be filled with heat to dry the probe 11.

[0058] The setting of the splash-proof plate 13.4 in the protective support assembly 13 can prevent liquid splashing as much as possible, protect the device and the surrounding environment, and avoid liquid pollution. During actual use, when the probe 11 is located in the cleaning tank 15, a cleaning tank cover can be set on the top of the cleaning tank 15 to cover the opening of the cleaning tank 15, further preventing liquid from splashing out. The support plate 13.3 can effectively support the cable 8 and increase its bending radius, preventing the outer skin of the cable 8 from cracking due to long-term bending and twisting. The modular design of the elastic sheet 14.6 is also convenient for regular inspection and replacement.

[0059] This device provides multiple cleaning and disinfection modes. The spray cleaning and disinfection method can quickly complete daily cleaning tasks; for immersion disinfection, the cleaning tank 15 is lifted by the lifting mechanism 20 to soak the probe 11 with a small amount of disinfectant, reducing the amount of disinfectant used while enhancing the disinfection effect, meeting the requirements of high hygiene standards. It improves the flexibility and practicality of the equipment, ensures hygienic safety in different scenarios, extends the service life of the probe 11 and optimizes resource utilization.
