Detailed Description
the present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1 and 2, a water bag for an external shock wave lithotripter with an ultrasonic probe coaxial (i.e. a shock wave central axis is concentric and coaxial with an ultrasonic central axis), comprises an external water bag 2 with an open bottom end and an internal water bag 1, wherein the internal water bag 1 is arranged in the external water bag 2, a top 11 of the internal water bag 1 and a part of a top 211 of the external water bag 2 are arranged in a same wall, i.e. in the present embodiment, the top 11 of the internal water bag 1 is smaller than a top 21 of the external water bag 2, and the center of the top 11 of the internal water bag 1 coincides with the center of the top 21 of the external water bag 2, so that the structure is more compact and the using effect is better.
Of course, in other embodiments, the center of the top 11 of the inner water bag 1 and the center of the top 21 of the outer water bag 2 may not coincide.
Of course, in other embodiments, the size of the top 11 of the inner water bag 1 can be equal to the size of the top 21 of the outer water bag 2, i.e. the top 11 of the inner water bag 1 and the top 21 of the outer water bag 2 are arranged in a same wall, which can be easily realized by those skilled in the art and will not be described in detail.
in this embodiment, outer water pocket 2 and interior water pocket 1 are integrated into one piece structure, and the sound construction, and the processing of being convenient for can adopt the integrative injection moulding of mould, can also adopt current other processing methods integrated into one piece of forming certainly, and this is that technical staff in the art can realize easily, no longer gives a detailed explanation. Of course, in other embodiments, the outer water bag 2 and the inner water bag 1 may be formed by splicing a plurality of discrete components.
In this embodiment, the outer water bag 2 and the inner water bag 1 are preferably made of silicone, but not limited thereto, and in other embodiments, the outer water bag 2 and the inner water bag 1 may also be made of other waterproof soft materials with elasticity, such as rubber.
In the embodiment, the thickness of the top 11 of the inner water bag 1 is preferably 0.5mm, which can not only ensure the strength requirement, but also reduce the attenuation of ultrasonic signals as much as possible, thereby improving the ultrasonic image quality. Of course, in other embodiments, the thickness of the top 11 of the inner water bag 1 can be selected according to actual needs, which can be easily realized by those skilled in the art and will not be described in detail.
In this embodiment, the side wall of the outer water bag 2 is a cylindrical structure, and the upper end of the outer water bag is provided with concave ring structures 23 and convex ring structures 22 which are alternately arranged along the axial direction, so as to prevent the water bag from sagging when being filled with circulating water, thereby preventing the water bag from affecting use.
In this embodiment, the number of the concave ring structures 23 is 2, the number of the convex ring structures is 3, and the sizes of the 3 convex ring structures are gradually decreased from bottom to top, so as to further prevent the water bag from sagging when being filled into the circulating water.
