DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1: A handle 1 is installed on the top of the ultrasonic probe body 2, and a mounting groove 16 is respectively opened inside the two sides of the ultrasonic probe body 2, and a second spring slide bar 14 is respectively installed inside the two mounting grooves 16, and a slider 15 is slidably installed on the outer side of the second spring slide bar 14, and a liquid storage box 3 is installed on one side of the slider 15, and a control rod 12 is installed on the top of the liquid storage box 3, and a plurality of movable grooves 19 are opened at equal intervals inside the liquid storage box 3, and a drainage tube 10 is installed inside the movable groove 19, and a coating pressure plate 7 is installed at the bottom end of the drainage tube 10, and a plurality of liquid outlets 9 are opened at equal intervals at the bottom of the coating pressure plate 7, and the liquid outlets 9 are connected with the interior of the drainage tube 10, and a liquid inlet 17 is opened inside the drainage tube 10, and a first spring slide bar 6 is respectively installed on both sides of the top of the coating pressure plate 7, and a limit block 5 is respectively installed on both sides of the liquid storage box 3, and the first spring slide bar 6 is slidably installed inside the limit block 5.
[0020] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, since a liquid storage box 3 is slidably installed on both sides of the ultrasonic probe body 2, when in use, the medical staff can control the liquid storage box 3 on one side to move downward according to the moving direction of the probe. Since a control rod 12 is installed at the top of the liquid storage box 3, and a handle 1 is installed at the top of the ultrasonic probe body 2, the handle 1 can be used to facilitate the medical staff to take the entire probe, and the control rod 12 can be used to facilitate the medical staff to squeeze the liquid storage box 3 with their fingers, so that the slider 15 installed on one side of the liquid storage box 3 moves downward along the installation direction of the second spring slide bar 14, and at the same time compresses the spring installed on the outside of the second spring slide bar 14. Since an application pressing plate 7 is installed below the liquid storage box 3, when the liquid storage box 3 moves downward, the bottom of the application pressing plate 7 will come into contact with the patient's skin. When the application pressing plate 7 is compressed, the first spring slide bars 6 installed on both sides of the top of the application pressing plate 7 will extend upward through the limit block 5, thereby compressing the spring installed on the outside of the first spring slide bar 6. At this time, the tops of multiple drainage tubes 10 installed on the top of the application pressing plate 7 will extend. Entering the liquid storage box 3, the coupling agent stored in the liquid storage box 3 will enter the interior of the drainage tube 10 through the liquid inlet 17 opened inside the drainage tube 10 and be smeared on the patient's skin through the liquid outlet 9. At this time, when the doctor moves the probe on the patient's skin, the coupling agent will be smeared on the patient's skin in advance, thereby improving the clarity of the detection image. After the examination is completed, the doctor will separate the ultrasonic probe body 2 from the patient's skin. At this time, the pressure on the smearing pressure plate 7 disappears, and the spring compressed on the outside of the first spring slide bar 6 rebounds, thereby storing the liquid inlet 17 into the inside of the movable groove 19, preventing the coupling agent from continuing to enter the interior of the drainage tube 10, thereby avoiding the coupling agent leakage when the probe is not in use. At this time, the doctor can cancel the squeezing of the liquid storage box 3, and the spring compressed on the outside of the second spring slide bar 14 will rebound, thereby moving the bottom end of the smearing pressure plate 7 to mid-air, avoiding one side of the liquid storage box 3 from contacting the patient's skin when not in use, causing the coupling agent to flow out, and avoiding wasteful use of the coupling agent.
[0021] Embodiment 2: A sealing cover 4 is installed at the top of the drainage tube 10, and the top of the drainage tube 10 is closed, a plurality of sealing covers 13 are installed at equal distances at the bottom of the liquid storage box 3, and the sealing cover 13 wraps the outer side of the drainage tube 10, a plurality of sealing rubber rings 18 are installed at equal distances at the bottom end of the interior of the liquid storage box 3 and the bottom of the sealing cover 13, and the sealing rubber ring 18 is sealed and connected to the outer side of the drainage tube 10, a plurality of silicone coating particles 8 are installed at equal distances at the bottom of the coating pressure plate 7, and the silicone coating particles 8 are used in conjunction with the liquid outlet 9, and a liquid injection port 11 is installed at the top of each of the two liquid storage boxes 3, and the liquid injection port 11 is communicated with the interior of the liquid storage box 3.
[0022] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since a sealing cover 4 is installed at the top of the drainage tube 10, when the liquid inlet 17 is received in the movable groove 19, the bottom end of the sealing cover 4 will contact the bottom end of the liquid storage box 3, thereby preventing the coupling agent stored in the liquid storage box 3 from entering the movable groove 19. Since a sealing rubber ring 18 is installed at the bottom end of the liquid storage box 3 and the bottom of the sealing cover 13 respectively, and the sealing rubber ring 18 is sealed and connected to the outer side of the drainage tube 10, the sealing performance can be further improved to avoid leakage of the coupling agent. Since a plurality of silicone coating particles 8 are equidistantly installed at the bottom end of the coating pressure plate 7, the outflowing coupling agent can be evenly applied to the patient's skin through the silicone coating particles 8. Since a liquid injection port 11 is installed at the top of the liquid storage box 3, the coupling agent can be injected into the liquid storage box 3 in advance through the liquid injection port 11, which is convenient for use.
[0023] Working principle: when in use, the coupling agent is injected into the two liquid storage boxes 3 through the liquid injection port 11 in advance, and then the medical staff controls the entire ultrasonic probe body 2 by holding the handle 1. When in use, the medical staff can control the liquid storage box 3 on one side to move downward according to the moving direction of the probe. Since a control rod 12 is installed at the top of the liquid storage box 3, and a handle 1 is installed at the top of the ultrasonic probe body 2, the handle 1 can be used to facilitate the medical staff to take the entire probe, and the control rod 12 can be used to facilitate the medical staff to squeeze the liquid storage box 3 with their fingers, so that the slider 15 installed on one side of the liquid storage box 3 moves downward along the installation direction of the second spring slide bar 14, and at the same time compresses the spring installed on the outside of the second spring slide bar 14. Since an application pressing plate 7 is installed at the bottom of the liquid storage box 3, when the liquid storage box 3 moves downward, the bottom of the application pressing plate 7 will come into contact with the patient's skin. When the application pressing plate 7 is compressed, the first spring slides installed on both sides of the top of the application pressing plate 7 The rod 6 will extend upward through the limit block 5, thereby compressing the spring installed on the outside of the first spring slide bar 6. At this time, the tops of the multiple drainage tubes 10 installed on the top of the smear pressure plate 7 will extend into the liquid storage box 3. The coupling agent stored in the liquid storage box 3 will enter the interior of the drainage tube 10 through the liquid inlet 17 opened inside the drainage tube 10 and be smeared on the patient's skin through the liquid outlet 9. At this time, when the doctor moves the probe on the patient's skin, since a plurality of silicone coating particles 8 are equidistantly installed at the bottom of the smear pressure plate 7, the outflowing coupling agent can be evenly applied to the patient's skin through the silicone coating particles 8. When the doctor needs to change to another square mobile probe, the control of the current liquid storage box 3 can be canceled. At this time, the rebound of the compressed springs on the outside of the first spring slide bar 6 and the second spring slide bar 14 can prevent the coupling agent from flowing out, and the unused liquid storage box 3 can be moved to one side of the ultrasonic probe body 2, and then the other liquid storage box 3 can be controlled in the same way for use.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
