[0002] B-ultrasound probes can convert electrical signals into high-frequency ultrasonic signals and transmit them into the human body. These ultrasonic signals will be reflected when encountering tissues and organs of different densities. In actual use, medical staff usually enter the patient's information into the computer first, then adjust the equipment, and then apply the coupling agent to the patient's part to be tested. After the coupling agent is applied, the ultrasound probe is taken to examine the patient. During the examination, if the coupling dose is insufficient or some places are not applied properly, the medical staff needs to take the coupling agent again for application, which will make the B-ultrasound examination process more inconvenient, increase the workload of medical staff, and reduce work efficiency.

[0019] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0020] Example

[0021] like Figure 1 and Figure 5As shown, it includes a B-ultrasound probe body, which is an existing technology. A medical ultrasound probe is a device that transmits and receives ultrasound waves during the ultrasonic detection process. The probe used in ultrasonic detection is a transducer that uses the piezoelectric effect of the material to realize the conversion of electrical energy and acoustic energy. The key component of the probe is the chip, which is a single crystal or polycrystalline thin piece with piezoelectric effect. Its function is to convert electrical energy and acoustic energy into each other;

[0022] The bottom end of the probe body is detachably provided with a housing 1, within which a number of partitions 2 are evenly distributed. The partitions 2 divide the interior of the housing 1 into a number of independent cavities, facilitating the storage of multiple couplants of uniform volume. This facilitates multiple uses and the selection of the amount of couplant applied according to the patient's condition, allowing medical staff to adjust the amount at any time during the application process, thereby reducing the difficulty of their work.

[0023] Each cavity is provided with a piston 4 that forms an interference fit therewith. A fixing rod 3 is vertically fixed to the top of the piston 4. A passage for the fixing rod 3 to pass through is provided at the top of the housing 1. An injection port 9 for injecting coupling agent into the cavity is provided on the housing 1. A sealing component is provided at the bottom of the cavity for cooperating with the piston 4 to squeeze the coupling agent onto the patient's skin. This facilitates the application of the coupling agent in the cavity to the patient's skin during testing and prevents leakage of the coupling agent in a natural state.

[0024] The shell 1 is made of a transparent material, and a scale line showing the coupling amount is provided on the shell 1 outside each independent cavity, so that when applying the coupling agent, a suitable amount can be selected according to the patient's condition, thereby reducing waste and lowering costs.

[0025] The sealing assembly includes a stopper 8. A countersunk hole for installing the stopper 8 is provided at the bottom of each cavity. A through hole communicating with each other from top to bottom is provided at the bottom of the countersunk hole, and the diameter of the through hole is smaller than that of the stopper 8. A "cross"-shaped opening for the passage of the coupling agent is provided at the center of the stopper 8. The opening fits tightly in the natural state, so that the coupling agent is blocked in the housing 1 to prevent leakage. When applying the coupling agent, the piston 4 is driven downward by pressing the fixing rod 3, and the coupling agent is squeezed by the piston 4 to open the opening of the stopper 8, so that the coupling agent seeps out from the opening and is then evenly applied to the patient's body.

[0026] like Figure 1 、 Figure 2 and Figure 5As shown, a fixing block 5 is provided on the top of the shell 1. The fixing block 5 is in a truncated cone-shaped structure as a whole, and a through groove for the B-ultrasound probe body to pass through is provided at the center of the fixing block 5. A groove for the fixing rod 3 to pass through is provided on the outer wall of the fixing block 5. A pressing plate 6 is provided in the groove to slide up and down with the fixing rod 3, and the bottom of the pressing plate 6 is fixed to the top of the fixing rod 3, so as to improve the comfort and stability when pressing the fixing rod 3, making it easier to squeeze the piston 4 to apply the coupling agent, and because of the setting of the fixing block 5, it is more comfortable to hold the B-ultrasound probe when the coupling agent does not need to be applied, thereby avoiding discomfort or even injury to the hands of medical staff caused by the fixing rod 3 during the detection process.

[0027] When the top of the piston 4 is in contact with the top of the housing 1, the highest point of the injection port 9 and the lowest point of the piston 4 are at the same level, which facilitates the injection of the coupling agent while reducing the risk of coupling agent leakage and the probability of coupling agent contamination. It also prevents the coupling agent from leaking from the channel during the upward and downward movement of the piston 4.

[0028] In order to improve the sealing effect during actual use, the injection port 9 can also be closed by providing a sealing plug.

[0029] like Figure 4 As shown, a chute for guiding the coupling agent is provided at the bottom of the housing 1. The chute is located directly below the stopper 8, and the diameter of the stopper 8 is equal to or smaller than the width of the chute, so that the coupling agent can flow downward along the chute to the patient's body after being squeezed out by the piston 4, thereby reducing the waste of the coupling agent and reducing costs, and facilitating the reduction of contamination to the B-ultrasound probe body, thereby reducing the difficulty of cleaning.

[0030] The housing 1 and the fixing block 5 are detachably connected to the B-ultrasound probe body via a connecting ring 7, which facilitates the installation of the present invention on an existing B-ultrasound probe via the connecting ring 7, thereby reducing the cost of replacing the probe and reducing the difficulty of work for medical staff;

[0031] The connecting ring 7 is interference fit with the B-ultrasound probe body, and the connecting ring 7 is connected to the housing 1 and the fixing block 5 via Velcro;

[0032] The connecting ring 7 and the B-ultrasound probe body can also be fixed with glue.

[0033] The inner wall of the connecting ring 7 is provided with an anti-slip layer to increase the friction between the connecting ring 7 and the B-ultrasound probe body, thereby preventing it from falling off during use;

[0034] The anti-slip layer can be made of rubber and silicone.

[0035] The working principle is to first move the piston 4 upward through the fixing rod 3 until the injection port 9 is located below the piston 4, and then inject the coupling agent into each independent cavity in the shell 1 through the injection port 9, and then press the pressure plate 6 and the fixing rod 3 to move the piston 4 downward to close the injection port 9. When the coupling agent needs to be applied, press the pressure plate 6 with your fingers to drive the fixing rod 3 to move downward, so that the coupling agent in the cavity is squeezed by the piston 4, so that the opening of the stopper 8 is opened to squeeze out the coupling agent, and the extruded coupling agent flows to the patient's body through the chute, and then it is evenly applied to the patient's body through the B-ultrasound probe body for detection; when in use, the shell 1 and the fixing block 5 can also be fixed to the existing B-ultrasound probe through the connecting ring 7, and then used in conjunction with the B-ultrasound probe.
