Description

Technical Field

[0001] This utility model relates to the field of stoma measurement technology, specifically to an automatic stoma measurement device. Background Technology

[0002] An ostomy is used to treat intestinal problems. After surgical removal of the diseased area, an opening is artificially created in the abdominal wall to allow a section of the intestine to be led out of the body. The intestinal tract is then turned over and sutured to the abdominal wall to form an intestinal stoma, which is used to involuntarily excrete feces or urine. An ostomy bag is also connected to the stoma via a stoma base plate to collect the excrement. The size and shape of the stoma base plate must be matched with the size and shape of the stoma to reduce the probability of skin complications around the stoma.

[0003] In order to cut out a stoma base plate that fits the stoma, the existing technology usually uses a circular measuring ruler to measure the stoma diameter. A circular measuring ruler with an appropriate diameter is selected according to the size of the stoma. The stoma base plate is cut out by measuring the diameter and visually estimating the approximate shape of the stoma. Then, the stoma base plate is connected and fixed to the stoma bag at the stoma.

[0004] In practice, the shape of the stoma is not always circular; it can also be elliptical or even irregular. Existing technology will produce large errors when measuring stomas of these shapes, which will make it difficult for the cut stoma base to fit the stoma. Utility Model Content

[0005] To address this issue, the present invention provides an automatic stoma measuring device to solve the technical problem that existing technologies produce large errors when measuring elliptical and irregularly shaped stomas, resulting in the difficulty in fitting the cut stoma base plate to the stoma.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] An automatic stoma measuring device includes a base, a measuring port on the base, an annular track on the base, and a slide seat movably mounted on the annular track.

[0008] A lifting seat is installed above the slide, and the lifting seat moves with the slide. A measuring element is installed at the bottom of the lifting seat, and the measuring element is directly opposite the inner side of the edge of the measuring port.

[0009] While the slide block slides on the circular track, the lifting seat drives the measuring element to move along the edge of the measuring port.

[0010] Furthermore,

[0011] A fixing rod is fixedly connected to the slide block, and a fixing seat is connected to the end of the fixing rod. A first drive motor is installed at the bottom of the fixing seat, and a threaded rod is connected to the drive end of the first drive motor.

[0012] The lifting seat is provided with a threaded hole that is threaded to the threaded rod and a sliding hole through which the fixed rod slides.

[0013] Furthermore,

[0014] The slide is equipped with a bearing, and the threaded rod is rotatably mounted on the slide via the bearing.

[0015] Furthermore,

[0016] A second drive motor is installed inside the slide block, and a rotating shaft is installed at the end of the second drive motor.

[0017] Furthermore,

[0018] Several rollers are movably mounted on the bottom of the slide block, and the rollers are in rolling contact with the annular track. The rotating shaft is connected to the rollers.

[0019] At least two of the rollers are disposed on the outer side of the annular track, and at least two of the rollers are disposed on the inner side of the annular track.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] In this invention, the measuring port is aligned with the stoma, and the measuring element is moved along the edge of the measuring port by the sliding block. During the movement, the measuring element reaches multiple measuring points directly opposite the stoma edge, allowing the measuring element to collect data at different stoma edge positions, thereby obtaining the actual shape and size of the stoma. The multi-point edge measurement method improves the accuracy of stoma measurement, and a stoma base that fits the stoma can be cut according to the measurement results. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1 , Figure 2 , Figure 4 As shown, this utility model provides an automatic stoma measuring device, including a base 1, a measuring port 11 on the base 1, an annular track 2 installed on the base 1, and a slide 3 movably installed on the annular track 2.

[0034] A lifting seat 4 is installed above the slide 3, and the lifting seat 4 moves with the slide 3. A measuring element 5 is installed at the bottom of the lifting seat 4, and the measuring element 5 is directly opposite the inner side of the edge of the measuring port 11.

[0035] While sliding on the circular track 2, the slide block 3 drives the measuring element 5 to move along the edge of the measuring port 11 via the lifting seat 4.

[0036] In this invention, the measuring port 11 is aligned with the stoma, and the measuring element 5 is moved along the edge of the measuring port 11 by the sliding base 3. During the movement, the measuring element 11 reaches multiple measuring points directly opposite the stoma edge, so that the measuring element 5 collects data at different stoma edge positions, thereby obtaining the actual shape and size of the stoma. The multi-point edge measurement method improves the accuracy of stoma measurement, and a stoma base plate that fits the stoma can be cut according to the measurement results.

[0037] like Figure 1 and Figure 3 As shown, in actual use, due to the different sizes of stomas, it is necessary to adjust the distance between the measuring element 5 and the stoma so that the measuring element 5 can capture the shape of the entire stoma. In order to achieve fully automated measurement of stoma size, this utility model designs a device that can automatically adjust the distance between the measuring element 5 and the stoma. Specifically, a fixed rod 8 is fixedly connected to the slide 3, and a fixed seat 6 is connected to the end of the fixed rod 8. A first drive motor 10 is installed at the bottom of the fixed seat 6, and a threaded rod 7 is connected to the drive end of the first drive motor 10. The lifting seat 4 is provided with a threaded hole that is threadedly engaged with the threaded rod 7 and a sliding hole for the fixed rod 8 to slide through. A bearing 9 is installed on the slide 3, and the threaded rod 7 is rotatably mounted on the slide 3 through the bearing 9.

[0038] When it is necessary to adjust the distance between the measuring element 5 and the stoma, the first drive motor 10 is turned on to drive the threaded rod 7 to rotate. At this time, the threaded rod 7 is threadedly engaged with the threaded hole on the lifting plate 4. Since the lifting plate 4 is connected to the fixed rods 8 on both sides of the threaded rod 7 through the sliding hole, the lifting plate 4 can only move up and down in the vertical direction, thereby realizing the automatic adjustment of the distance between the measuring element 5 and the stoma.

[0039] like Figure 4 As shown, the bearing 9 is embedded in the slide 3. The bearing 9 includes an inner ring and an outer ring. The bottom of the threaded rod 7 is connected to the inner ring of the bearing 9, and the outer ring of the bearing 9 is fixedly connected to the slide 3.

[0040] Since the slide block 3 needs to slide on the circular track 2 to drive the measuring element 5 to measure the stoma edge at a fixed point, in order to enable the slide block 3 to slide on the circular track 2, a second drive motor is installed inside the slide block 3, a rotating shaft is installed at the end of the second drive motor, and several rollers 12 are movably installed at the bottom of the slide block 3. The rollers 12 are in rolling contact with the circular track 2, and the rotating shaft is connected to the rollers 12.

[0041] At least two rollers 12 are located on the outer side of the annular track 2, and at least two rollers 12 are located on the inner side of the annular track 2. The rollers 12 on the outer side and the rollers 12 on the inner side clamp the annular track 2, so that the slide block 3 can slide smoothly.

[0042] The second drive motor drives the rotating shaft at its end to rotate, and the roller 12 rolls in contact with the circular track 2. When the slide 3 slides, it needs to maintain a slow and steady speed to obtain a clear stoma image and ensure that the measuring element 5 has enough time to capture the stoma edge feature points, thereby improving the accuracy of the measurement.

[0043] like Figure 5 , Figure 6 As shown, this utility model is based on AR measurement technology. The measuring element 5 measures the actual size of the stoma at multiple points. After measurement, a graphic of the stoma's shape and size is simultaneously generated on the mobile phone. This graphic can be oriented on the phone, allowing users to adjust the cutting direction according to their needs. The generated graphic can be overlaid on a base template (which consists of multiple concentric circles of different diameters), printed out, and then cut to serve as a cutting template for the stoma base plate. During cutting, the edge of the center hole of the stoma base plate should be 1-2mm larger than the stoma edge to prevent bleeding between the center hole edge and the stoma. Alternatively, if printing is inconvenient, the APP provides a base template consisting of multiple concentric circles. The generated graphic is overlaid on these concentric circles, allowing users to trace the graphic on the stoma base plate before cutting.

[0044] like Figure 7 As shown, the relationship between the actual measurement results and the stoma baseplate can be used to cut the stoma baseplate. If it is still difficult to trace, this graphic can be printed out. Cut out the red graphic, and the hole in the middle is the actual shape of the stoma. The cut graphic can be traced on the stoma baseplate with a pen before cutting. This way, a stoma baseplate of the appropriate size can be cut, and the cutting direction can be controlled, solving the difficulties encountered by nursing staff and stoma patients in cutting stoma baseplates. Appropriate stoma baseplate cutting can prevent the occurrence of peristomal skin complications.

[0045] In this invention, the measuring element can be an acquisition device such as an optical sensor. The optical sensor can capture stoma images and use computer vision technology to process the images and identify the stoma.

[0046] It should be noted that obtaining information on the shape and size of the stoma using AR measurement technology requires the combination of measurement element 5 with computer vision technology, SLAM technology, and other technologies. Computer vision technology, SLAM technology, and other technologies are relatively mature technologies at present, and will not be elaborated here.

[0047] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
