Therefore, the above terms should not be understood as limiting the present invention.

Greater than, less than, and more than are understood to exclude the number itself, and above, below, and within are understood to include the number itself. If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] The following is combined with Figure 1-5 , an embodiment of the utility model of an automatic spraying device for medical ultrasonic coupling agent is further described in detail.

[0032] A medical ultrasonic coupling agent automatic spraying device, such as Figures 1 to 3 As shown, it includes a base 1 for placing an ultrasonic probe 8, a fixing base 2 arranged above the base 1 for installing a coupling agent 9, and a support rod 3 connected between the base 1 and the fixing base 2, an infrared sensing probe 4 and a coupling mechanism 5 are arranged on the fixing base 2, and a plurality of infrared sensing probes 4 are arranged, and the plurality of sensing probes are evenly arranged at the bottom end of the fixing base 2; the coupling mechanism 5 is arranged in the fixing base 2, and one end of the coupling mechanism 5 is connected to the coupling agent 9; when the ultrasonic probe 8 is placed on the base 1, the infrared sensing probe 4 automatically detects the size and position of the ultrasonic probe 8, and accurately and evenly sprays the coupling agent 9 on the ultrasonic probe 8 through the coupling mechanism 5.

[0033] Specifically, general medical ultrasonic probes 8 need to be used in conjunction with coupling agent 9. When applying the coupling agent 9, it is usually squeezed manually onto the ultrasonic probe 8, which is prone to uneven application and excessive squeezing, resulting in waste. The medical ultrasonic coupling agent 9 automatic spraying device of the utility model uses a built-in infrared sensing probe 4, a coupling mechanism 5 and a control mechanism 6, and uses the infrared sensing probe 4 to detect the shape and size of the ultrasonic probe 8 in real time, thereby realizing automatic recognition of the ultrasonic probe 8 and precise spraying of the coupling agent 9. At the same time, the coupling mechanism 5 can automatically and accurately apply the coupling agent 9 to the ultrasonic probe 8, thereby realizing automated operation, improving spraying efficiency, reducing waste of coupling agent 9, and ensuring the accuracy of each inspection.

[0034] It is worth noting that the multiple infrared sensing probes 4 arranged at the bottom of the fixing base 2 use infrared sensing technology to accurately identify the size and shape of the ultrasonic probe 8, thereby facilitating the coupling mechanism 5 to control the amount of the sprayed coupling agent 9 according to the size of the ultrasonic probe 8.

[0035] In this embodiment, if Figure 3 , 4 As shown, the coupling mechanism 5 includes a fixed slide rod 51, a connecting tube 52 and a nozzle 53. The fixed slide rod 51 is laterally connected to the inner wall of the fixed seat 2, and a hollow slide groove 511 is opened in the middle position of the fixed slide rod 51. One end of the connecting tube 52 is connected to the coupling agent 9, and the other end passes through the slide groove 511 and is connected to the nozzle 53. The nozzle 53 is slidably connected to the fixed slide rod 51 along the direction of the slide groove 511.

[0036] Specifically, when the nozzle 53 and the fixed slide bar 51 are spraying the coupling agent 9, their working principle is similar to that of an inkjet printer, wherein the nozzle 53 has the functions of vacuum suction and injection, and under the action of the fixed slide bar 51, the nozzle 53 can move along the slide groove 511, and at the same time, an opening 21 matching the slide groove 511 is opened at the bottom end of the fixed seat 2 corresponding to the position of the nozzle 53, so that the coupling agent 9 is evenly sprayed on the ultrasonic probe 8 from the opening 21, and the connecting pipe 52 connects the coupling agent 9 and the nozzle 53, playing a transmission role, so when the ultrasonic probe 8 is sprayed with the coupling agent 9, the nozzle 53 sucks and sprays the coupling agent 9 on the ultrasonic probe 8 through the connecting pipe 52, and moves slowly along the fixed slide bar 51, and at the same time, the coupling mechanism 5 cooperates with the infrared sensing probe 4 to automatically identify the size and shape of the ultrasonic probe 8, and then in the process of spraying the coupling agent 9, the application amount can be accurately controlled and waste can be reduced, and it can also automatically replenish when the coupling agent 9 is lacking on the ultrasonic probe 8; thereby greatly improving the working efficiency of the coupling agent 9 extrusion.

[0037] In this embodiment, a control mechanism 6 is further provided on the fixing seat 2 for coordinating the work of various components and controlling the amount of coupling agent 9 applied according to preset parameters. The control mechanism 6 is electrically connected to the infrared sensing probe 4 and the coupling mechanism 5 respectively; wherein the control mechanism 6 includes a microprocessor 61, a control valve body 62 and a driving member 63; the microprocessor 61 is electrically connected to the power supply, and is respectively connected to the control valve body 62 and the driving member 63 through wires; the control valve body 62 is installed on the connecting pipe 52, and is used to control the start and stop of the nozzle 53 spraying the coupling agent 9; the driving member 63 is transmission-connected to the nozzle 53, and is used to drive the nozzle 53 to move left and right along the slide groove 511.

[0038] Specifically, the control mechanism 6 can automatically adjust the amount of the coupling agent 9 applied, so that it has the advantages of simple operation and convenient maintenance, and can be widely used in the field of medical ultrasonic imaging; wherein the control mechanism 6 controls the coupling mechanism 5 to spray the work flow including the following steps:

[0039] Step S1, start the device and insert the coupling agent 9 upside down into the mounting cavity 22 on the fixing base 2;

[0040] Step S2, placing the ultrasonic probe 8 into the base 1 along the notch 11, with the probe facing upward;

[0041] Step S3, the control mechanism 6 automatically detects the size, shape and position of the ultrasonic probe 8 using the infrared sensing probe 4, and controls the coupling mechanism 5 through the driving member 63 to adjust the position and angle of the nozzle 53 according to the detection result of the infrared sensing probe 4;

[0042] Step S4, the coupling mechanism 5 extracts the coupling agent 9 by vacuum and moves along the fixed slide bar 51, so that the coupling agent 9 is evenly sprayed on the surface of the ultrasonic probe 8;

[0043] Step S5: After the spraying is completed, the control valve body 62 controls the nozzle 53 to close and prepare for the next time.

[0044] It is worth mentioning that the microprocessor 61 adopts the single-chip microcomputer control principle, can collect and process the signals sent by the infrared sensing probe 4, and can also change the control programming according to needs. The control valve body 62 is used to control the opening or closing of the nozzle 53, thereby achieving the effect of automatic coating; the drive member 63 can be controlled by a drive motor or a cylinder.

[0045] In this embodiment, if Figure 5As shown, a mounting cavity 22 for invertedly placing the coupling agent 9 is provided on the top of the fixing seat 2, and a limiting assembly 7 is provided in the mounting cavity 22. The limiting assembly 7 is used to fix the depth of the coupling agent 9 inserted into the mounting cavity 22 so that the outlet end of the coupling agent 9 is connected to the connecting pipe 52; wherein, the limiting assembly 7 comprises a limiting block 71, a limiting sleeve 72 and a limiting rod 73, one end of the limiting block 71 is fixedly connected to the limiting sleeve 72, and the other end is connected to the inner wall of the mounting cavity 22, and the shape of the limiting sleeve 72 is adapted to the coupling agent 9; one end of the limiting rod 73 is connected to the bottom of the limiting block 71, and a return spring 74 is provided on the outer side of the limiting rod 73.

[0046] Specifically, the limiting components 7 are provided on both sides of the installation cavity 22 in order to quickly align and connect the coupling agent 9 to the connecting tube 52, so as to avoid the coupling agent 9 from being wasted during the spraying process. The corresponding limiting components 7 can also effectively fix the connecting tube 52 to prevent it from being offset and detached when transmitting the coupling agent 9, resulting in the problem of wasting the coupling agent 9. When the coupling agent 9 is inserted into the installation cavity 22 under the action of its own gravity, the arc-shaped limiting sleeves 72 on both sides can limit and fix it. At the same time, the limiting rod 73 overcomes the action of the reset spring 74 and presses downward. The limiting block 71 is used to fix the position of the limiting rod 73, thereby locking the position of the coupling agent 9 so that one end of the discharge is inserted into the connecting tube 52, which is convenient for saving labor and realizing the automatic locking of the coupling agent 9 and aligning it with the connecting tube 52. After the coupling agent 9 is used up, the coupling agent 9 is pressed again with a slight force, and the limiting rod 73 returns to its original position under the elastic action of the reset spring 74. The restriction of the coupling agent 9 can be released.

[0047] In this embodiment, if Figure 2 As shown, the base 1 is adapted to the shape of the ultrasonic probe 8 to form a trumpet-shaped structure, and a notch 11 is provided on the side wall of the base 1 , and the notch 11 is used to clip and connect the power cord of the ultrasonic probe 8 .

[0048] Specifically, in order to facilitate the rapid replenishment of the coupling agent 9 on the ultrasonic probe 8 after use, the ultrasonic probe 8 is placed on the base 1 and the coupling mechanism 5 is automatically aligned, so that the infrared sensing probe 4 can quickly identify the ultrasonic probe 8 and replenish it through the coupling mechanism 5, thereby saving the problem of manually controlling the amount of coupling agent 9 sprayed during manual application, and avoiding the waste caused by manual squeezing of the coupling agent 9.

[0049] The working principle of this utility model:

[0050] When applying coupling agent 9 to the ultrasonic probe 8, the ultrasonic probe 8 is placed upward in the base 1, and the coupling agent 9 is inverted and inserted into the installation cavity 22 of the fixing seat 2, and the discharge end of the coupling agent 9 is fixed to be connected with the connecting pipe 52 under the action of the limiting component 7. At the same time, the infrared sensing probe 4 arranged on the bottom end of the fixing seat 2 senses the size and shape of the ultrasonic probe 8 by emitting infrared rays, and feeds back the signal to the control mechanism 6. The microprocessor 61 controls the control valve body 62 to open, so that the nozzle 53 automatically vacuum extracts the coupling agent 9, and evenly sprays the coupling agent 9 according to the surface shape information of the ultrasonic probe 8 fed back by the infrared sensing probe. After the coupling agent 9 is used up, it only needs to be pressed lightly to automatically unlock the lock of the limiting component 7, which is convenient for replacement. By setting the infrared sensing probe 4 and the coupling mechanism 5, the coating efficiency and uniformity of the coupling agent 9 are greatly improved, the waste of the coupling agent 9 is reduced, and the labor intensity of medical staff is reduced, thereby providing more efficient and accurate services for medical ultrasonic imaging.

[0051] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
