Problems solved by technology

But this type of smear will produce a lubricating effect, and this lubricating effect is completely harmful to the shock wave lithotripsy process, because when the patient's skin is in contact with the water bladder, it will be shaken by the impact of the water bladder, so The lubricating effect at this time will easily cause the position of the skin in contact with the water bladder to shift easily, causing the shock wave action to deviate from the position of the stone, thus greatly affecting the effect of stone crushing; It is necessary to clean off the smears on the surface of the skin and water bladder, but such smears are often difficult to clean, especially when patients often need to perform multiple lithotripsy, which increases the burden and causes great inconvenience

Embodiment 1

[0032] like image 3 As shown, in this embodiment, the outer sticking layer 3 adopts a stopper gel layer 9 fixed on the elastic base cloth 1, and the flexible structure of the stopper gel layer 9 can be closely attached to the surface of the water bladder, and it can be attached under pressure. High friction force can be generated between the stop gel layer 9 and the water bladder at the right time (the material of the gel itself makes its surface have a high friction coefficient), and the elastic reinforcing mesh 10 strengthens the strength of the stop gel layer 9 , so that it can effectively resist stretching, thereby effectively preventing the stop gel layer 9 from shifting from the water bladder when the shock wave is impacted, ensuring the accuracy of the crushed stone position and improving the crushing effect.

[0033] After the patient completes the stone crushing, if the next stone crushing is required, the elastic release film 5 can be attached to the surface of the ...

Embodiment 2

[0035] like Figure 4As shown, the difference between this embodiment and Embodiment 1 is that the outer layer 3 adopts the self-adhesive layer 11 distributed layer by layer on the lower side of the elastic base cloth 1, and the two adjacent layers of the self-adhesive layer 11 pass through each other. The elastic diaphragm 12 is separated, so that through the tight bonding between the self-adhesive layer 11 and the surface of the water bag, the purpose of expelling the air between the water bag and the water bag and effectively preventing movement is also achieved. In addition, in the next stone crushing, the used self-adhesive layer 11 can be peeled off by tearing off the elastic diaphragm 12 of the previous layer, so that the unused self-adhesive layer 11 is exposed, and the multi-layer self-adhesive layer 11 The setting can be adapted to multiple gravel use.

Abstract

The invention discloses a urinary calculus positioning auxiliary device, and relates to the technical field of urinary calculus positioning devices. The elastic fabric comprises elastic base cloth, the upper side of the elastic base cloth is provided with an inner attaching layer used for attaching human skin, and the lower side of the elastic base cloth is provided with an outer attaching layer used for attaching the surface of an extracorporeal lithotripter water bag. Release paper is attached to the surface of the inner attaching layer; an elastic release film is attached to the surface of the outer attaching layer; the inner sticking layer comprises a skin sticking gel layer fixedly stuck on the upper side of the elastic base cloth, inner side adhesive layers discontinuously distributed on the upper side of the elastic base cloth, and outer side adhesive layers annularly distributed on the upper side of the elastic base cloth; the skin-attaching gel layer correspondingly surrounds the inside adhesive layer; and the outer side adhesive layer correspondingly surrounds the skin-attaching gel layer. The lithotripter has the advantages that the skin position corresponding to calculus can be marked, the stability degree of the contact position of a patient and the water bag is improved, the lithotripsy effect is guaranteed, and in addition, inconvenience and burden caused by smear cleaning can be avoided.

Description

technical field [0001] The invention relates to the technical field of positioning devices for urinary calculi. Background technique [0002] Before extracorporeal shock wave lithotripsy is performed on patients with urinary calculi, it is necessary to take B-ultrasound, urography and other inspection measures to confirm the position of the calculi, and then make the patient take a suitable position on the treatment bed, so that the water bladder of the lithotriptor can resist the calculi Position (mark in advance on the skin corresponding to the stone position), and use the transmission effect of the water bladder on the shock wave energy to achieve the stone crushing operation. [0003] During the stone crushing process, in order to ensure that the shock wave energy transmitted by the water bladder can fully act on the stone in the patient, it is necessary to apply a couplant or a smear such as Vaseline on the skin corresponding to the stone position of the patient to ensu...
