Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to an ultrasonic probe coupling agent applying device with quantitative supply. Background Art

[0002] B-ultrasound is an examination method based on B-mode ultrasound, which can obtain various relatively clear sectional images of the examined part. The ultrasonic probe is an important device for transmitting and receiving ultrasonic waves during B-ultrasound examination. During B-ultrasound examination, the air between the ultrasonic probe and the skin will reflect ultrasonic waves, hinder the transmission of ultrasonic waves into the human body, and affect the quality of B-ultrasound images. To obtain high-quality B-ultrasound images, it is necessary to apply ultrasonic coupling agent to fill the tiny gap between the probe and the surface contact of the body surface.

[0003] During the specific operation of ultrasonic examination, the ultrasonic probe needs to be kept in a sterile state. Due to the material of the ultrasonic probe itself, excessive disinfection may damage its internal electronic components and cause equipment damage. Therefore, in clinical use, doctors usually cover the surface of the ultrasonic probe with sterile gloves to ensure that the ultrasonic probe is not contaminated. Although this measure plays a certain protective role for the probe, since the ultrasonic coupling agent cannot be applied, the quality of B-ultrasound imaging decreases, reducing the success rate of clinical operations. In addition, currently in clinical practice, the coupling agent is generally directly squeezed by hand, which will cause waste of the coupling agent and uneven application.

[0004] Therefore, it is necessary to propose an ultrasonic probe coupling agent applying device with quantitative supply for realizing the sterile protection of the ultrasonic probe and the quantitative application of the ultrasonic coupling agent. Content of the Utility Model

[0038] The clamping and fixing assembly 22 includes a rear cover plate 221, a rack clamp block 222, a sector gear connecting rod 223, a push rod 224, a first connecting rod 225 and a return spring 226.

[0039] The rear cover plate 221 is connected to the rear end face of the base 21 and covers the remaining components of the clamping and fixing assembly. The rack clamp blocks 222 are symmetrically arranged on the left and right sides of the inner side of the rear cover plate 221. Chutes are symmetrically arranged in the middle of the inner side of the rear cover plate 221. Rectangular protrusions are arranged on the side of the rack clamp block 222, and the rectangular protrusions slide in the chutes to complete the clamping action of the rack clamp block 222 on the coupling agent extrusion bottle 1.

[0046] The following further describes a quantitative supply ultrasonic probe coupling agent application device of the present utility model in conjunction with embodiments. The usage process of the quantitative supply ultrasonic probe coupling agent application device of the present utility model is as follows:

[0047] When the device needs to be used, cover the protective sleeve 32 outside the ultrasonic probe 31, and place the inner coating tube 36 between the ultrasonic probe 31 and the protective sleeve 32. The side of the inner coating tube 36 with the spraying port faces the ultrasonic probe 31. Use the elastic binding band 33 to sleeve the bottom of the protective sleeve 32 to fix the protective sleeve 32 and the ultrasonic probe 31 together. Place the ultrasonic probe 31 together with the protective sleeve 32 into the probe box 34. Place the outer coating tube 37 between the protective sleeve 32 and the probe box 35. The side of the outer coating tube 37 with the spraying port faces the protective sleeve 32, and then cover the probe cover 35. The first ends of the inner coating tube 36 and the outer coating tube 37 are sequentially connected to the second end of the coupling agent extrusion bottle 1.

[0048] Flip the toggle switch of the push rod 224 upward to cause the rack clamp 222 to move horizontally away from the center of the device. Then place the coupling agent extrusion bottle 1 into the quantitative extrusion device 2 with the bottom surface of the coupling agent extrusion bottle 1 closely attached to the inner side surface of the rear cover plate 221. Release the toggle switch of the push rod 224, and the push rod 224 moves downward under the reset contraction of the reset tension spring 226, driving the rack clamp 222 to move horizontally closer to the center of the device, completing the centering, fixing, and clamping of the coupling agent extrusion bottle.

[0049] Turn on the motor 239. Through the threaded transmission of the screw rod 237 and the threaded slider 236, the rotation of the output shaft of the motor 239 is transformed into the rotation of the turntable 231. Under the limitation of the rotating pair between the link slider 234 and the turntable 231 and the moving pair between the link slider 234 and the second link 233, the rotation of the turntable 231 drives the second link 233 to swing towards the center of the device, and the coupling agent extrusion bottle 1 is extruded through the pressure ring 235 to quantitatively supply the coupling agent to the inner coating tube 36 and the outer coating tube 37.

[0050] The coupling agent is respectively applied between the inner surface of the ultrasonic probe 31 and the protective sleeve 32 and on the outer surface of the protective sleeve 32 through the spraying ports of the inner coating tube 36 and the outer coating tube 37.

[0051] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model.
