Description

Technical Field

[0001] This invention belongs to the field of stoma base technology, specifically a stoma base cutting and positioning scale auxiliary mold. Background Technology

[0002] The stoma baseplate is a core consumable for the daily care of stoma patients. Before use, the center opening needs to be cut according to the actual size of the patient's stoma. The size and accuracy of the opening directly affect the stoma care effect: if the opening is too large, it is easy for excrement to leak and irritate the surrounding skin, causing redness and swelling dermatitis; if the opening is too small, it will continuously rub against the stoma mucosa, causing bleeding and pain. Therefore, it is crucial to accurately measure the stoma and replicate the standard outline before cutting.

[0003] Traditional measurement methods involve only one side of the ruler touching the stoma, which cannot guarantee that the measurement center coincides with the stoma center, making it easy for the left and right dimensions to be asymmetrical. The ends of ordinary rulers are mostly right-angled and hard, which can easily compress and irritate the delicate stoma tissue when it is placed against the stoma, causing discomfort to the patient. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary mold for cutting and positioning the stoma base plate, so as to solve the problems mentioned in the background art.

[0007] The positioning mechanism includes a positioning rod that slides through and is slidably connected to one side of the mold housing, used to position the size of the stoma;

[0008] The marking component includes a marker pen arranged on the mold housing for marking the size of the stoma on the chassis.

[0009] As a further preferred embodiment of this technical solution, the positioning mechanism also includes:

[0010] Positioning rod two is slidably connected to the other side of the mold shell and is used to cooperate with positioning rod one for positioning;

[0011] Rack 1 is fixedly arranged on positioning rod 1 and slidably connected in the cavity inside the mold shell;

[0013] Rack 2 is meshed with the upper end of the spur gear and slidably connected in the cavity inside the mold housing. It is used to drive positioning rod 2 to move synchronously, and one end of rack 2 is fixedly arranged on one side of positioning rod 2.

[0014] As a further preferred embodiment of this technical solution: the end of positioning rod one near the center of the mold housing is arc-shaped, and the end of positioning rod two near the center of the mold housing is arc-shaped.

[0015] As a further preferred embodiment of this technical solution: a groove is provided at one end of the two arc-shaped positioning rod.

[0016] As a further preferred embodiment of this technical solution, the positioning mechanism also includes:

[0017] A slot is provided on the positioning rod to limit the positioning rod.

[0018] The locking post is slidably connected to the mold housing, and its lower end is engaged in the locking groove;

[0019] The spring is fixed at one end to the mold housing and at the other end to the lower end of the retaining post.

[0020] As a further preferred embodiment of this technical solution: several sets of slots are provided and are evenly distributed on the upper surface of the positioning rod.

[0021] As a further preferred embodiment of this technical solution, the marking component also includes:

[0022] A slider is used to support the marker, and the marker is installed in a circular structure at one end of the slider;

[0023] A fixing bolt, threaded through, is connected to the slide bar to fix the marker pen, with one end of the fixing bolt abutting against the marker pen;

[0024] The rod tube is used to limit the movement of the slide rod, and the slide rod is slidably connected inside the rod tube.

[0025] A limiting ring is used to limit the position of the rod and cylinder, and the rod and cylinder are fixedly arranged on the limiting ring;

[0026] The limiting groove is provided on the mold shell, and the limiting ring is slidably connected to the limiting groove.

[0027] As a further preferred embodiment of this technical solution: two sets of fixing bolts are provided, one set is provided on the circular structure at one end of the slide rod, and the other set is threadedly connected to the rod cylinder, which is used to limit the slide rod.

[0028] As a further preferred embodiment of this technical solution: one end of the marker extends into the groove at the arc-shaped end of the positioning rod.

[0029] As a further preferred embodiment of this technical solution: the limiting ring is a T-shaped ring, and the limiting groove is a T-shaped groove that fits the limiting ring, used for limiting the rotation of the marker pen during marking.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In this invention, a gear and rack linkage structure is adopted. Pulling one side of the positioning rod can realize the synchronous and equal extension and retraction of the two positioning rods, always keeping the center of the mold and the center of the stoma aligned, without any unilateral deviation. The inner sides of the two positioning rods are both arc-shaped end faces, which can gently conform to the outline of circular and elliptical stomas without sharp corners irritating the wound. With the multi-position slot and locking spring structure, stomas of different diameters can be stably fixed in size. Single-person operation is required without assistance, which greatly reduces the measurement error of stoma size and is suitable for the stoma specifications of most patients.

[0032] 2. In this invention, a groove is provided at the end of the positioning rod to limit the tip of the marker pen during marking, ensuring that the marking radius is completely consistent with the measured stoma size; the marking component is equipped with double fixing bolts to lock the marker pen and the sliding rod respectively, so that the pen body will not loosen or the sliding rod will retract during the marking process. Together with the T-shaped limiting ring and the T-shaped limiting groove, a ring guide structure is formed, and the rotating marking trajectory is smooth and regular. The size and position of the cut base opening fit the stoma height, effectively avoiding leakage of feces due to excessively large openings and friction damage to the skin around the stoma due to excessively small openings, reducing the probability of complications such as dermatitis and redness.

[0033] 3. This mold integrates the functions of stoma size measurement and base plate contour marking into one unit, eliminating the need for separate tools such as rulers, compasses, and markers, thus simplifying the operation process for medical staff and patients at home; the slide bar can be extended and adjusted within the tube to adapt to different sizes of stoma base plates, and the marker is easy to disassemble and replace. The entire device has a simple structure and is easy to use. Attached Figure Description

[0045] Example

[0046] Please see Figures 1-5 As shown, the present invention provides a technical solution: an auxiliary mold for cutting and positioning the stoma base, comprising:

[0047] Mold housing 1, used for supporting devices;

[0048] The positioning mechanism includes a positioning rod 201 that slides through and is connected to one side of the mold housing 1, for positioning the size of the stoma;

[0049] The marking component includes a marker 301 disposed on the mold housing 1 for marking the size of the stoma on the chassis.

[0050] It should be noted that the center of the mold housing 1 is aligned with the center of the patient's stoma, and the diameter size is measured by using the positioning rod 201 against the edge of the stoma. After the measurement is completed, the cutting marks matching the size of the stoma are copied on the base plate laid on the mold housing 1 with the marker pen 301. The size positioning and marking functions are integrated into one, eliminating the need to use two separate tools, a ruler and a marker pen. The operation steps are simplified, making it convenient for medical staff or patients to independently complete the stoma base plate opening positioning at home.

[0051] In this embodiment, the positioning mechanism further includes: a second positioning rod 202, which is slidably connected to the other side of the mold housing 1 and is used to cooperate with the first positioning rod 201 for positioning; a first rack 203, which is fixedly arranged on the first positioning rod 201 and slidably connected in the cavity inside the mold housing 1; a spur gear 204, which is rotatably connected to the mold housing 1 and the first rack 203 is meshed with the lower end of the spur gear 204; and a second rack 205, which is meshed with the upper end of the spur gear 204 and slidably connected in the cavity inside the mold housing 1, for driving the second positioning rod 202 to move synchronously, and one end of the second rack 205 is fixedly arranged on one side of the second positioning rod 202.

[0052] When the positioning rod 201 is pulled outward, the rack 203 moves synchronously to drive the spur gear 204 to rotate. The spur gear 204 drives the rack 205 to move synchronously in the opposite direction, causing the positioning rod 202 to extend symmetrically and synchronously with the positioning rod 201. The ends of the two positioning rods synchronously fit against the edges of the stoma, automatically achieving centered symmetrical measurement. The gear and rack linkage structure ensures that the positioning rods on both sides extend and retract synchronously and equally. During measurement, the center of the mold and the center of the stoma are always aligned, avoiding positioning offset caused by pulling on one side, and greatly improving the symmetry and positioning accuracy of stoma size measurement.

[0053] In this embodiment, specifically: the end of positioning rod 201 near the center of mold housing 1 is arc-shaped, and the end of positioning rod 202 near the center of mold housing 1 is arc-shaped.

[0054] It should also be understood that the inner curved ends of the two positioning rods fit the outer curved surface of the circular or elliptical stoma. The curved surface can completely fit the edge contour of the stoma, without sharp corners poking or irritating the stoma wound. The curved ends fit the shape of the stoma, adapting to various conventional circular stomas. The contact is gentle, and there is no sharp end pressing on the stoma during the measurement process, improving the comfort of use. At the same time, the fit is higher and the dimensional measurement error is smaller.

[0055] In this embodiment, specifically: a groove is provided at one end of the arc-shaped positioning rod 202.

[0056] In addition, the groove forms a limiting and accommodating space. During marking operations, the tip of the marker pen 301 can be inserted into the groove. When rotating to draw lines, the pen tip always stays at the measured stoma radius position and will not deviate radially. The groove radially limits the pen tip, ensuring that the drawing radius is completely consistent with the actual measured stoma size, preventing the pen tip from sliding during the drawing process and causing the marking size to be too large or too small, thus improving the drawing accuracy.

[0057] In this embodiment, the positioning mechanism further includes: a slot 206, which is provided on the positioning rod 201 and is used to limit the positioning rod 201; a locking post 207, which is slidably connected to the mold housing 1 and whose lower end is locked in the slot 206; and a spring 208, one end of which is fixedly provided on the mold housing 1 and the other end of which is fixedly provided at the lower end of the locking post 207.

[0058] It should be noted that after pulling the positioning rod 201 to adjust it to fit the stoma size, the spring 208 presses down the locking post 207 to engage with the corresponding slot 206. The locking action of the locking post and the slot locks the extension length of the positioning rod 201, limiting the retraction of the positioning rod 201 and the positioning rod 202. After the measurement is completed, the positioning size is automatically locked. After releasing the hand, the positioning rod will not spring back and shift. One person can hold the mold with one hand and rotate the marker pen with the other to draw lines without the need for assistance from others to fix the positioning rod, making the operation convenient.

[0059] In this embodiment, specifically: the card slots 206 are provided in several groups and are evenly distributed on the upper surface of the positioning rod 201.

[0060] When the positioning rod 201 is extended to different lengths, the corresponding slot 206 can be engaged with the locking post 207, and any sprue size can be locked and fixed. The multi-position uniform slots are suitable for sprues of different diameters, the size adjustment range is continuous, and all kinds of sprue sizes can be stably locked, making the mold more widely applicable.

[0061] In this embodiment, specifically: the marking assembly further includes: a slide bar 302 for supporting the marker pen 301, and the marker pen 301 is installed in a circular structure at one end of the slide bar 302; a fixing bolt 303, threadedly connected to the slide bar 302 for fixing the marker pen 301, and one end of the fixing bolt 303 abutting against the marker pen 301; a rod cylinder 304 for limiting the slide bar 302, and the slide bar 302 is slidably connected inside the rod cylinder 304; a limiting ring 305 for limiting the rod cylinder 304, and the rod cylinder 304 is fixedly arranged on the limiting ring 305; and a limiting groove 306, formed on the mold housing 1, and the limiting ring 305 is slidably connected to the limiting groove 306.

[0062] It should also be understood that the marker 301 is inserted into the round hole at the end of the slide bar 302, and the fixing bolt 303 is tightened to clamp and fix it; the slide bar 302 can slide back and forth in the rod tube 304 to adjust the extension length and adapt to different thickness chassis; the whole assembly rotates around the center of the mold along the limiting groove 306 through the limiting ring 305 to complete the ring contour marking. The marker is easy to disassemble and replace, the slide bar is telescopic and adjustable to adapt to various chassis thicknesses, the limiting ring and the limiting groove cooperate to achieve stable circumferential rotation, the marking is smooth and without jamming, and one set of components can be adapted to multiple stoma chassis.

[0063] In this embodiment, specifically: the fixing bolts 303 are provided in two sets, one set is provided on the circular structure at one end of the slide rod 302, and the other set is threadedly connected to the rod cylinder 304, which is used to limit the slide rod 302.

[0064] In addition, a set of fixing bolts clamps the marker pen to prevent it from rotating or falling off; another set of bolts locks the relative position of the slide rod and the tube. After adjusting the extension length of the slide rod, it is locked so that the slide rod will not retract during the marking process. The double bolts lock the marker pen and the slide rod respectively, making the overall structure of the marking component stable. When rotating to draw lines, the pen body will not loosen or the slide rod will retract, ensuring that the thickness and size of the marking line are consistent throughout the process.

[0065] In this embodiment, specifically: one end of the marker 301 extends into the groove at the arc-shaped end of the positioning rod 202.

[0066] It should also be understood that after the size is locked, the slide bar is pushed forward, and the marker tip is inserted into the groove. The groove limits the distance from the pen tip to the center of the mold to be equal to the actual measured stoma radius. Rotating along the annular groove can replicate the standard circular outline of the stoma. The groove precisely limits the scribing radius, and the position of the pen tip always matches the actual measured size of the stoma. The scribing outline and the actual stoma diameter are completely consistent. After cutting, the base opening fits the stoma to avoid leakage and friction irritation to the skin.

[0067] In this embodiment, specifically: the limiting ring 305 is a T-shaped ring, and the limiting groove 306 is a T-shaped groove that fits the limiting ring 305, used to limit the rotation of the marker pen 301 during marking.

[0068] The T-shaped limiting ring is inserted into the T-shaped limiting groove, and can only slide in a circular motion along the circumference of the groove. It cannot detach upwards or shift left or right, which drives the marker pen 301 to rotate smoothly around a standard circular trajectory to complete the marking. The T-shaped structure prevents detachment and deviation, and the rotating marking trajectory is neat and rounded, without problems such as uneven markings, broken lines, or eccentricity. The marking quality is high. The sliding is smooth and effortless, and can be easily operated by the elderly and caregivers.

[0069] Working principle or structural principle: During operation, first align the center of the mold housing 1 with the center of the stoma, pull the positioning rod 201 outward, and the rack 203 fixed to the positioning rod 201 will move synchronously and mesh with the central spherical gear 204 to rotate. The upper end of the spherical gear 204 meshes with the rack 205 and drives the positioning rod 202 to extend synchronously and symmetrically, so that the inner arc-shaped ends of the positioning rods 201 and 202 fit against the left and right edges of the stoma to complete the size alignment. Multiple sets of slots 206 are evenly arranged on the positioning rod 201. The locking post 207 on the mold housing 1, which is pressed down by the spring force of the spring 208, can automatically lock into the corresponding slot 206 to achieve size locking and prevent the positioning rod from springing back and shifting. The groove opened at the arc-shaped end of the positioning rod 202 is used to accommodate the tip of the marker pen 301. The marker pen 301 is installed in the round hole at the front end of the slide rod 302 and passes through the slide rod 302. The fixing bolt 303 clamps and fixes the slide rod 302, which is inserted into the rod tube 304. The fixing bolt 303 of the rod tube 304 can adjust the extension length of the slide rod 302 to adapt to different sizes of base markings. The T-shaped limiting ring 305 fixed to the bottom of the rod tube 304 is embedded in the matching T-shaped annular limiting groove 306 on the mold housing 1. It can only rotate smoothly around the circumference of the limiting groove 306. After measuring the locking size, the stoma base is laid flat on the surface of the mold housing 1. The extension length of the slide rod 302 is adjusted so that the tip of the marker pen 301 fits the base and is inserted into the groove at the end of the positioning rod 202. By holding the rod tube 304, the limiting ring 305 is rotated around the center of the mold housing 1 along the annular limiting groove 306. The opening outline that is completely consistent with the actual size of the stoma can be copied on the base. The subsequent cutting of the base along the line can effectively avoid the problem of the opening being too large, too small, or misaligned.
