Problems solved by technology

Since the adsorption device relies on negative pressure to fix the ultrasonic probe, and the surface of the human body is not flat and smooth, a slight collision or disturbance will cause the adsorption device to leak and loosen, thus affecting the stability of the ultrasonic probe fixation

Embodiment 1

[0045] In this embodiment, the structure of the bonding type medical external ultrasonic probe is as follows: figure 1 , figure 2 As shown, it consists of a probe body, an adhesive layer 4, and a protective layer 5. The main part of the shell 1 of the probe body is in the shape of a spherical crown, the bottom surface is a circular plane, and a window 3 for exposing the transducer is opened. The height of the shell 1 of the probe body is 1 / 4 of the radius of the bottom circle. The viscous layer 4 is a self-adhesive layer covering all parts of the shell bottom of the probe body except the window 3 . The protective layer 5 is a plastic film covering on the adhesive layer.

Embodiment 2

[0047] In this embodiment, the structure of the bonding type medical external ultrasonic probe is as follows: image 3 , Figure 4 As shown, it consists of a probe body, an adhesive layer 4, and a protective layer 5. The main part of the shell 1 of the probe body is in the shape of a quadrangular prism, the bottom surface is square, and it is concave downward to form an arc surface, and a window 3 for exposing the transducer is opened. The height of the shell 1 of the probe body is 1 / 2 of the side length of the square on its bottom surface. The viscous layer 4 is a self-adhesive layer covering all parts of the shell bottom of the probe body except the window 3 . The protective layer 5 is a plastic film covering on the adhesive layer.

Embodiment 3

[0049] In this embodiment, the structure of the bonding type medical external ultrasonic probe is as follows: Figure 5 , Image 6As shown, it consists of a probe body, a flexible sticking board 6 made of polyethylene, an adhesive layer 4 and a protective layer 5 . The main part of the shell 1 of the probe body is spherical, the bottom surface is a circular plane, and there is a window 3 for exposing the transducer; the paste plate 6 is a circular flat plate, and the height of the shell of the probe body is the radius of the outer circle of the paste plate. one third. Paste plate 6 is installed around the shell bottom surface of probe body and clamped with the shell bottom surface. Adhesive layer 4 is a self-adhesive layer covering the bottom surface of paste plate 6. Protective layer 5 is a plastic film covered on the viscous layer.

Abstract

The invention provides a sticking type medical in-vitro ultrasonic probe, which is formed by a probe body, a sticking layer and a protective layer, wherein a window for exposing an energy converter is arranged on the bottom face of a shell of the probe body; the sticking layer covers all the parts of the bottom face of the shell of the probe body except the window; the protective layer covers the sticking layer; or the sticking type medical in-vitro ultrasonic probe is formed by the probe body, a flexible sticking plate manufactured by a medical high molecular material, the sticking layer and the protective layer; the sticking plate is an annular plate, is mounted around the bottom face of the shell, and is connected with the bottom face of the shell; the sticking layer covers the bottom face of the sticking plate and the protective layer covers the sticking layer; or the sticking type medical in-vitro ultrasonic probe is formed by the probe body, a flexible cap sleeve manufactured by the medical high molecular material, the sticking layer and the protective layer; the sticking plate and the cap sleeve are in an integrated structure or a splitting structure; a lead wire bundle which is connected with the energy converter in the probe body stretches out of a through hole arranged on the cap sleeve; and a sticking layer covers the bottom face of the sticking plate, and the protective layer covers the sticking layer.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a medical external ultrasonic probe of an ultrasonic diagnostic instrument. Background technique [0002] The ultrasonic diagnostic instrument is an instrument that generates incident ultrasonic waves (transmitting waves) into human tissue through an ultrasonic probe, and simultaneously receives reflected ultrasonic waves (echoes) from various interfaces of human tissue, and then processes these reflected signals to obtain images of human tissue. Ultrasonic probe As an important part of the ultrasonic diagnostic instrument, it plays a decisive role in the detection effect. [0003] Existing medical external ultrasound probes generally have a non-fixed structure. When in use, the doctor holds it in his hand, presses it on the detection site of the examinee, and rotates or moves the ultrasound probe according to the needs of the image to obtain the required ultrasound image.
