B-type ultrasonography probe socket

Abstract

The invention relates to the field of a medical instrument, and specifically relates to a B-type ultrasonography probe socket. The B-type ultrasonography probe socket mainly comprises a cable, a socket circuit assembly and a probe housing. The probe housing comprises an upper casing and a base plate, the upper casing is provided with an indicating lamp, the bottom of the upper casing is in close fit with the base plate, and the base plate is provided with a first cable port; the socket circuit assembly is arranged in the probe housing; and the first end of the cable is connected with a B-type ultrasonography probe, and the second end of the cable passes through the first cable port to be connected with a circuit board in the socket circuit assembly. According to the invention, the B-type ultrasonography probe socket is arranged by use of a mode of combining the upper casing and the base plate, such that a long-strip-shaped slit in the outer surface of the housing can be prevented, the EMC protection grade and waterproof grade of the product are greatly improved, the upper casing is simple in structure and facilitates arrangement of the indicating lamp, whether the probe works and whether the probe is at a frozen state or a work state can be clearly determined from appearance through the indicating lamp, and the wrong plugging of the probe is prevented during replacement of the probe.

Description

technical field [0001] The invention relates to the field of medical instrument products, in particular to a B-ultrasound probe socket. Background technique [0002] The B-ultrasound probe socket is the connection port between the B-ultrasound probe and the B-ultrasound host. The conventional B-ultrasound probe socket uses the left and right two-petal metal shells to assemble the internal parts required, and then fixes them with screws. In this way, the left and right two-petal shells The shape is generally symmetrical, and the internal parts are required to be fixed on one of the outer shells, which makes the assembly and fixation of the internal functional parts closely related to the shape of the upper shell, which cannot be independent of the upper shell; In addition, the left and right two-piece shell will leave a long contour gap on the middle mating surface, which is also unfavorable for the high EMC (Electro Magnetic Compatibility) protection level requirements of t...

[0002] The B-ultrasound probe socket is the connection port between the B-ultrasound probe and the B-ultrasound host. The conventional B-ultrasound probe socket uses the left and right two metal shells to assemble the parts required inside. components, and then fixed with screws, the left and right shells in this way are generally symmetrical in appearance, requiring internal components to be fixed on one of the shells, which makes the assembly and fixing of internal functional components consistent with the upper shell. The shape of the shell is very relevant, and it cannot be independent of the upper shell; in addition, the left and right two-lobed shell will leave a long contour gap on the middle mating surface, which is very important for the EMC (electromagnetic compatibility) of the B-ultrasound probe socket. , Electro Magnetic Compatibility) higher protection level requirements are also unfavorable

Moreover, the structure of the left and right two-lobed shell is not conducive to setting the working status indicator on the shell, and the working status of the probe cannot be directly judged from the senses, which may cause the possibility of users pulling out by mistake
