Embodiment Construction

[0042] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0043] Such as Figure 12(a) , 12(b) As shown in and 3-5, the device for measuring the shape of the hip surface and its normal pressure distribution proposed in a preferred embodiment of the present invention is based on the hydraulic principle (Pascal principle) and the principle of static friction balance. Mechanical devices with positive pressure distribution (the stress distribution form with only normal pressure and no tangential shear stress), including the hip curve and the pressure sensing device I and the pressure testing device II; respectively correspond to image 3 Shown as Part I and Part II. The hip curve and pressure sensor device I and the pressure test device II are composed of many discrete sensors, such as image 3 The sensing unit 1 and the reading unit 2 are shown; and there is a one-to-one correspondence between the sensing unit 1 of the I-...

Abstract

The present invention discloses a device for measuring a buttock curved surface shape and normal pressure distribution thereof. The device comprises a buttock-curved-surface and pressure sensing device and a pressure measuring device, which both consist of discrete sensors; the sensors of both devices are one-to-one corresponding and make up of a fluid-pressure communicating vessel by being connected by copper tubes; the sensors are located at both sides of the fluid-pressure communicating vessel and respectively formed by the fixed connection between a sensing unit and a pressure-sensing wafer capable of free rotating; and the sensors are arranged in a ball chamber which is directly and fixedly connected with a piston. The invention also discloses a method for measuring the buttock curved surface shape and the normal pressure distribution thereof. The device and the method provide a certain basis for the introduction of mechanics to enterology and the development of the research of bio-mechanics in anus diseases.

Description

Technical field [0001] The invention relates to a mechanical design based on mechanics and an experimental data analysis method based on calculus and differential geometry, and relates to a device for quantitatively measuring the shape of the buttocks curved surface and its positive pressure distribution; in addition, the invention also relates to measuring the shape of the buttocks curved surface and its positive pressure Method of distribution. Background technique [0002] Anal fistula is a common anorectal disease, and surgery is the fundamental treatment. In clinical practice, "tunnel dragging" is often used to treat anal fistulas. Postoperative anal fistula patients often use "sandbag sitting pressure" to promote the closure of the fistula lumen and achieve the goal of cure. This method has a relatively mature clinical basis and good therapeutic effect; but there is no in-depth research on the scientific aspect of this "sandbag sitting pressure therapy". Summary of the in...
