DETAILED DESCRIPTION

[0032] The present invention will be further explained below in conjunction with specific embodiments.

[0033] refer to Figure 1 The present invention relates to a stoma measurement device, which has a measurement structure. The measurement structure includes a fixed outer ring 5, which is in a circular ring shape. At least four circular openings are opened on the surface of the fixed outer ring. The four circular openings are symmetrically arranged in pairs. Each circular opening penetrates the fixed outer ring 5. Force transmission columns 61 are respectively penetrated on two of the circular openings. A push plate 6 for pushing the force transmission column 61 is arranged on one end of the force transmission column 61 located on the outer wall of the fixed outer ring 5, and a connecting column 62 is arranged on one end of the force transmission column 61 located on the inner wall of the fixed outer ring 5.

[0034] The connecting column 62 is columnar, and a circular hole is formed on the surface of the connecting column 62. The base ring 53 passes through one connecting column 62, and the other telescopic ring 54 passes through the other connecting column 62. A connector 52 is provided at the connection between each base ring 53 and the telescopic ring 54, and the base ring 53 and the telescopic ring 54 can slide inside the connector 52. In order to improve the installation convenience of the device, first, the base ring 53 and the telescopic ring 54 can be divided into two sections, and the two sections of the base ring 53 are fixed by screwing, and correspondingly, the two telescopic rings 54 are fixed by screwing. Second, a "C"-shaped opening can be formed on the side wall of the connecting column 62 close to the outer surface of the base ring 53, and the base ring 53 can pass through the "C"-shaped opening and contact the inner wall of the connecting column 62, and finally fix the base ring 53 in the connecting column 62; correspondingly, the same "C"-shaped opening is formed on the connecting column 62 used to connect the telescopic ring 54, so that the telescopic ring 54 is fixed in the corresponding connecting column 62.

[0035] In order to prevent the base ring 53 and the telescopic ring 54 from being separated from the connector 52 during the sliding process, which would affect the measurement results, a fixing hole is formed on the surface of the base ring 53, and a similar fixing hole is formed on the surface of the telescopic ring 54. A moving groove with an annular structure is formed on the outer wall surface of each connector 52. A fixing column 51 on one side passes through the moving groove and the fixing hole on the surface of the base ring 53 in sequence to connect the base ring 53 and the connector 52. A fixing column 51 on the other side passes through the moving groove and the fixing hole on the surface of the telescopic ring 54 in sequence to connect the telescopic ring 54 and the connector 52.

[0036] Reference Figure 2 The outer wall diameters of the base ring 53 and the telescopic ring 54 can also be set to two specifications, one large and one small. The outer wall diameter of the base ring 53 can be larger than the outer wall diameter of the telescopic ring 54, or the outer wall diameter of the base ring 53 can be smaller than the outer wall diameter of the telescopic ring 54. When the outer wall diameter of the base ring 53 is the larger diameter, the telescopic ring 54 is inserted into the interior of the base ring 53; when the outer wall diameter of the base ring 53 is the smaller diameter, the telescopic ring 54 is inserted outside the base ring 53.

[0037] The outer wall diameter of the entire base ring 53 can be set to a larger diameter or a smaller diameter; the outer wall diameter of part of the base ring 53 can also be set to a larger diameter or a smaller diameter; when the outer wall diameter of part of the base ring 53 is a larger diameter or a smaller diameter, the outer wall of the base ring 53 is divided into a non-reduced diameter portion and a reduced diameter portion, wherein the length of the reduced diameter portion should be equal to the length of the connector 52, and the outer wall of the base ring 53 or the outer wall of the telescopic ring 54 at the larger diameter in the reduced diameter portion should contact the inner wall of the connector 52, and at the same time, the outer wall of the base ring 53 or the outer wall of the telescopic ring 54 at the smaller diameter in the reduced diameter portion should contact the inner wall of the telescopic ring 54 or the inner wall of the base ring 53 at the larger diameter.

[0038] When the base ring 53 and the telescopic ring 54 are connected using larger diameter and smaller diameter, the movable grooves on the surface of the connector 52 should be circular and evenly distributed, and the fixing holes on the surface of the base ring 53 and the fixing holes on the surface of the telescopic ring 54 should both be circular and evenly distributed. At the same time, the fixing holes on the surface of the base ring 53 and the fixing holes on the surface of the telescopic ring 54 can overlap.

[0039] Since the shape of the stoma is irregular, the base ring 53 and the telescopic ring 54 need to be made of a shape-changeable memory alloy so that when facing an irregular stoma shape, the edge of the base ring 53 or the edge of the telescopic ring 54 can fit the stoma. Embodiment 1

[0040] The user places the measuring structure on the stoma of the patient and observes the fit of the stoma. The user first ensures that each side fixing column 51 is in a loose state to avoid the problem that the base ring 53 or the telescopic ring 54 cannot move due to the locking of the side fixing column 51. The user pushes the connecting column 62 to move by the push plate 6. The connecting column 62 drives the base ring 53 or the telescopic ring 54 at the corresponding position to move toward the stoma position or away from the stoma position, driving the side fixing column 51 connected to the base ring 53 to move on the surface of the connector 52. The side fixing column 51 that moves in the movable groove or is connected to the telescopic ring 54 moves in the movable groove on the surface of the connector 52 until the inner wall of the device fits the outer wall of the stoma. The user tightens the side fixing column 51 so that the front end outer wall of the side fixing column 51 passes through the fixing hole and contacts the inner wall of the connector 52. The side fixing column 51 fixes the base ring 53 or the telescopic ring 54 at the current position, thereby realizing measurement. The user places the measuring structure on the stoma base, outlines the edges with a marker pen, and then cuts the base.

[0041] When the outer walls of all base rings 53 are of a larger diameter, and the outer walls of all telescopic rings 54 are of a smaller diameter, and the telescopic ring 54 is inserted into the interior of the base ring 53, the user first removes the side fixing column 51, and then drives the telescopic ring 54 to move in a direction close to the base ring 53 or away from the base ring 53 through the push plate 6 until it moves to a suitable position, and then fixes at least one side fixing column 51 on the movable groove on the surface of the connector 52.

[0042] When the outer walls of all telescopic rings 54 have a larger diameter, and the outer walls of all base rings 53 have a smaller diameter, the working principle is the same as above.

[0043] When the outer wall of the base ring 53 has a larger diameter, and part of the outer wall of the telescopic ring 54 has a smaller diameter, and the reduced diameter portion of the outer wall of the telescopic ring 54 is inserted into the reduced diameter portion of the base ring 53, the working principle is the same as before.

[0044] When part of the outer wall of the base ring 53 has a smaller diameter and the outer wall of the telescopic ring 54 has a larger diameter, and the outer wall variable diameter portion of the telescopic ring 54 is sleeved on the outer periphery of the outer wall variable diameter portion of the base ring 53, the working principle is the same as before.

[0045] When the stoma has an irregular shape, after the inner wall of the device roughly fits the outer wall of the stoma and the side fixing column 51 is locked, the user drives the force transmission column 61 through the push plate 6 to apply pressure to the base ring 53 or the telescopic ring 54, causing the corresponding position of the base ring 53 or the telescopic ring 54 to change its shape to fit the outer wall of the stoma.

[0046] In order to improve the degree of fit of the device to the irregular stoma, when the device is used to measure the irregular stoma, several circular openings for passing the force transmission columns 61 may be provided through the surface of the fixed outer ring 5 . Embodiment 2

[0047] In order to avoid the problem of damage to the stoma base and waste of resources caused by manual cutting errors after the user uses the measuring structure, a shearing structure is designed to connect it with the measuring structure recorded in Example 1, thereby realizing integrated measurement-cutting workmanship.

[0048] Combination Figure 3 A stoma measurement device includes, in addition to a measuring structure, a shearing structure matching the measuring structure. The shearing structure includes a mounting groove 10 for fixing the measuring structure. The mounting groove 10 is arranged on an intermediate fixing plate 8. The interior of the intermediate fixing plate 8 is hollow. A top structure 1 is connected to the upper part of the intermediate fixing plate 8 through an upper telescopic plate 7, and a base 11 is connected to the lower part of the intermediate fixing plate 8 through a lower fixing plate 9.

[0049] The top structure 1 and the base 11 are retractably connected, and a cutting blade 4 for cutting the stoma base is installed at the top structure 1; an outer ring 12 for fixing the stoma base is installed on the base 11.

[0050] The top structure 1 has an upper surface and a lower surface, and a top inner cavity 15 is formed between the upper surface and the lower surface. A partition is vertically arranged in the top inner cavity 15, and the partition divides the top inner cavity 15 into a first top inner cavity and a second top inner cavity, wherein the space of the first top inner cavity is small, and the space of the second top inner cavity is large; at the same time, the bottom end surface of the first top inner cavity is open.

[0051] like Figure 6 and Figure 7 As shown, the way to achieve the telescopic connection between the top structure 1 and the base 11 is: in the first top inner cavity, and on the side wall of the partition close to the first top inner cavity, a rotating base column 35 is installed through a bearing, and a winding structure is connected to the front end of the rotating base column 35 through a connecting rod 32. The winding structure includes a winding column 36 and a front baffle 33 or a rear baffle 34 arranged at both ends of the winding column 36. The front end of the front baffle 33 is connected to the adjusting wheel 3 arranged outside the top structure 1 through a connecting rod 32.

[0052] A pull rope 31 is wound around the winding column 36. The pull rope 31 is made of a thin steel wire rope. After the lower end of the steel wire rope passes through the lower end opening of the first top inner cavity, it passes through the upper telescopic plate 7, the middle fixed plate 8 and the lower fixed plate 9 from top to bottom in sequence, and is fixed on the bottom end of the lower fixed plate 9; at the same time, a slide groove is provided at the position where the middle fixed plate 8 connects to the upper telescopic plate 7, and the lower fixed plate 9 is fixedly connected to the middle fixed plate 8. In this way, after the user rotates the connecting rod 32 through the adjusting wheel 3 to drive the pull rope 31 to wind around the surface of the winding column 36, the steel wire rope becomes shorter and generates force. The lower fixed plate 9 and the middle fixed plate 8 are fixedly connected, and the upper telescopic plate 7 and the middle fixed plate 8 are slidably connected. The upper telescopic plate 7 becomes a force point, and the force will drive the upper telescopic plate 7 to move in the direction close to the lower fixed plate 9, thereby achieving downward pressure on the top structure 1.

[0053] Combination Figure 4 , Figure 8 and Fig. 9 The connection method between the top structure 1 and the cutting blade 4 is as follows: a plurality of blade moving grooves 21 are arranged in a circumferential manner on the lower surface of the top structure 1, and the lower surface of the top structure 1 opposite to each blade moving groove 21 is open. The blade moving grooves 21 do not contact each other and the front ends of the blade moving grooves 21 do not cross at the center of the top structure 1.

[0054] A cutting blade 4 is installed in each blade moving groove 21, and the rear end of the cutting blade 4 is connected to the outer wall of the bottom end of the turbine connecting column 24 through a blade expansion plate 23. The bottom end of the turbine connecting column 24 is connected to the center position of the top structure 1 through a bearing, and a turbine 22 is fixedly installed at the upper end of the turbine connecting column 24.

[0055] A fixing ring 16 is arranged on the periphery of the turbine connecting column 24 and in the top inner cavity 15. The bottom end of the fixing ring 16 is connected to the bottom end surface of the top structure 1 where the blade moving groove 21 is not arranged through a supporting leg. A circular hole is opened at the height position of the fixing ring 16 corresponding to the turbine 22. The rear end of a worm 19 passes through the fixing ring 16 and is connected to the operating wheel 2 located outside the top structure 1; the worm 19 and the turbine 22 are meshed and can achieve self-locking.

[0056] The blade expansion piece 23 is a flat iron that can be wound around the surface of the turbine connecting column 24. When the user drives the turbine connecting column 24 to rotate and retract by engaging the turbine 22 with the worm 19, the blade expansion piece 23 is forced to fit the surface of the turbine connecting column 24.

[0057] Combination Figure 5 and Fig.10The base 11 has a lower end with a cavity and an upper end for closing the upper end surface of the lower end of the base. A rotating motor 17 is installed in the upper end cavity of the base 11. The shaft end of the rotating motor 17 is connected to the lower end surface of the upper end of the base 11. An outer ring 12 is rotatably arranged on the upper end surface of the upper end of the base 11. A buckle plate 13 is arranged on the upper surface of the outer ring 12. The buckle plate 13 is installed on the surface of the outer ring 12 by a hinge. When the user places the uncut stoma base on the outer ring 12, the user can buckle the buckle plate 13 by the hinge to achieve the purpose of pressing the stoma base. In order to ensure that the stoma base will not be displaced during cutting, the number of the buckle plates 13 is set to at least three.

[0058] Two circular grooves are provided on the surface of the base 11 and on the inner side of the outer ring 12, and the centers of the two circular grooves are the same but the diameters are different; an inner ring 14 is provided on the circular groove with a larger diameter, and an adjustable inner ring 20 is connected to the circular groove with a smaller diameter; both the inner ring 14 and the adjustable inner ring 20 are connected to the surface of the base 11 through a concave-convex structure; when the measuring structure is located between the outer ring 12 and the inner ring 14, the user can remove the adjustable inner ring 20, and the cutting blade 4 cuts the stoma base between the outer ring 12 and the inner ring 14 along the measuring structure; when the measuring structure is located on the inner side of the inner ring 14, the user can install the adjustable inner ring 20 on the base 11, and the cutting blade 4 cuts the stoma base between the inner ring 14 and the adjustable inner ring 20 along the measuring structure.

[0059] The working principle is: after the user measures the required stoma size through the measuring structure, the user determines whether to use the adjustable inner ring 20 according to the size of the measuring structure, and then fixes the measuring structure on the shearing structure through the mounting groove 10. At the same time, the user places the stoma base to be cut on the surface of the outer ring 12 and fixes it through the buckle plate 13. The user controls the rotation of the worm 19 through the operating wheel 2, and the worm 19 engages the turbine 22 to rotate. The turbine 22 rotates on the bottom end surface of the top structure 1 through the bearing installed at the bottom end of the turbine connecting column 24, thereby driving the blade expansion piece 23 on the periphery of the turbine connecting column 24 to move along the blade moving groove 21 until the outer wall of the cutting blade 4 fits the inner wall of the measuring structure.

[0060] At this time, the user rotates the adjusting wheel 3, and the pull rope 31 inside the adjusting wheel 3 is wound around the winding column 36, thereby driving the upper telescopic plate 7 to move downward on the inner side of the middle fixed plate 8, pressing the cutting blade 4 at the bottom end of the top structure 1 to the stoma base, and with the gradual downward movement of the upper telescopic plate 7, the cutting blade 4 gradually passes through the stoma base, producing a point cutting on the stoma base.

[0061] It should be noted that if it is a stoma of regular shape, the rotating motor 17 can be turned on at this time. The rotating motor 17 drives the surface of the base 11 to rotate, and the outer ring 12 starts to rotate synchronously, driving the stoma base to rotate and contact the cutting blade 4 to cut the stoma base; but if it is an irregularly shaped stoma, after point cutting, the user needs to outline the irregular position and then perform manual cutting to improve the overall fit of the stoma base.

[0062] At the same time, a rotating motor 17 needs to be set up in this application. The rotating motor is any micro motor in the prior art that can realize the work of this application. Therefore, the model of the motor is not explained. At the same time, the rotating motor 17 is powered by connecting an external socket through a power plug with a control switch.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
