Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a stoma measurement and sampling device. Background Technology

[0002] Stoma placement (such as colostomy, ileostomy, urostomy, etc.) is a common surgical procedure for treating diseases such as rectal cancer and bladder cancer. Post-operatively, a stoma baseplate (ostomy bag) needs to be attached to the abdominal wall stoma site to collect waste. To prevent leakage and corrosion of the surrounding healthy skin, the cut-out diameter of the stoma baseplate must perfectly match the shape and size of the patient's stoma. Currently, the commonly used measurement methods in clinical practice include the following:

[0003] Measuring ruler: Usually a paper or plastic card with circular holes of different diameters printed on it. When using it, medical staff place the circular holes of different diameters over the stoma for comparison.

[0004] Copying gauge: Originally used in decoration or carpentry, it uses parallel sliding steel pins to replicate the shape of an object.

[0005] However, in actual clinical practice, whether using measuring cards or profilometers, operators need to hold the device with both hands suspended in the air and rely on visual observation and subjective feel to determine whether the plane of the measuring tool is parallel to the stoma cross-section. Because the human abdominal wall is usually curved (e.g., convex or lateral), lacking a natural plane reference, it is extremely difficult for operators to maintain the device stably horizontally for extended periods while suspended in the air. Even a slight tremor or tilt of the hand will create an angle between the measuring plane and the stoma cross-section, causing projection distortion of the measured contour shape (e.g., measuring a circular stoma as an ellipse). This measurement error, caused by the inability to objectively level the stoma, directly leads to inaccurate stoma baseplate cutting, resulting in nursing problems such as excrement leakage, skin redness and ulceration. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a stoma measurement and sampling device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A stoma measurement and sampling device is provided, comprising:

[0009] Connector;

[0010] The first shaping component and the second shaping component each have one end hinged to the connecting seat and the other end being a free end;

[0011] The first and second shaping components are rotatable around the connecting seat to come closer to each other to enclose a measurement area between them;

[0012] A support member is disposed on the side of the connector facing the skin, the support member including a support skirt and a support rod with one end fixed to the support skirt;

[0013] The other end of the support rod is connected to the connecting seat through a ball joint structure, which allows the connecting seat to tilt at multiple angles relative to the support skirt.

[0014] A level bubble level is provided on the end face of the connector away from the skin to indicate the horizontal state of the connector.

[0015] Preferably, both the first shaping component and the second shaping component include:

[0016] Several shaping needles are slidably arranged side by side within the first shaping component and the second shaping component, and are used to move into the measurement area under the action of thrust to adapt to the contour of the stoma.

[0017] Preferably, both the first shaping component and the second shaping component include:

[0018] A magnetic suction element is disposed at the free ends of the first shaping component and the second shaping component, for locking the free ends when the two components close to form the measurement area;

[0019] A constraint member is disposed at the free ends of the first shaping component and the second shaping component and adjacent to the magnetic suction member, for limiting the axial displacement of both in the closed state.

[0020] Preferably, the constraint includes:

[0021] A positioning cone is provided on the free end face of the first shaping component;

[0022] And a positioning recess provided on the free end face of the second shaping component and adapted to the positioning cone.

[0023] Preferably, the end of the profiling needle facing the measurement area is provided with a hemispherical or arc-shaped blunt contact.

[0024] Preferably, the support rod has a height-adjustable structure to adjust its overall length.

[0025] Preferably, the support rod includes:

[0026] The first rod and the second rod are threaded together to form the height-adjustable structure.

[0027] Preferably, it includes:

[0028] A cleaning tank is provided in the main body of the first shaping component and the second shaping component;

[0029] The cleaning tank is located along the sliding path of the forming needle.

[0030] Preferably, it includes:

[0031] The free ends of the first shaping component and the second shaping component are provided with a toggle protrusion or a finger groove.

[0032] Preferably, the plurality of shaping needles includes needle bodies of at least two different colors;

[0033] The needles of different colors are arranged alternately at predetermined intervals.

[0034] This utility model provides a stoma measurement and sampling device, and the beneficial effects of this utility model are reflected in:

[0035] When the bubble level indicator shows the bubble is centered, it indicates that the connecting seat and the forming component hinged to it are on an absolutely horizontal plane. This ensures that the measurement of the stoma is performed on a horizontal projection plane after eliminating the influence of the abdominal curvature, effectively avoiding projection distortion. Furthermore, the support component, as a stabilizing point of the device, effectively prevents hand tremors or fatigue caused by prolonged suspension of the device by the operator. This solves the problem of measurement plane instability caused by relying entirely on manual balance in existing technologies, improving the stability of the measurement process and the reproducibility of the results.

[0042] 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.

[0043] Please see Figures 1-4 As shown, the specific embodiments provided by this utility model are as follows:

[0044] like Figures 1 to 3 As shown, an embodiment of this utility model proposes a stoma measurement and shaping device, including a connecting seat 1, a first shaping component 2, a second shaping component 3, and a support member located at the bottom.

[0045] The first shaping component 2 and the second shaping component 3 are located on opposite sides of the connecting seat 1, with one end of each component hinged to the connecting seat 1, forming a rotatable connection; the other end of each component is a free end, not subject to fixed constraints. Based on this hinged structure, the first shaping component 2 and the second shaping component 3 can rotate horizontally around the connecting seat 1. When they rotate inward to approach each other, they enclose a measurement area for accommodating the stoma.

[0046] To address the measurement errors caused by the non-planar nature of the skin around the stoma in the human abdomen (such as convexity or slope), this embodiment includes a support member on the side of the connecting seat 1 facing the skin (i.e., the bottom of the device). This support member consists of a support skirt 401 and a support rod 402. The support skirt 401 is located at the bottom of the device and is used to directly contact the skin (or sterile cloth) surface on the stoma side during measurement operations. One end of the support rod 402 is fixedly connected to the support skirt 401 and extends upward to support the components above.

[0047] The other end of the support rod 402 is connected to the connecting seat 1 using a ball joint structure, which allows for multi-angle tilting and swinging relative to the lower support skirt 401. Therefore, regardless of the tilt angle of the bottom support skirt 401 due to its contact with the skin, the upper connecting seat 1 can be independently adjusted in position.

[0048] To assist the operator in adjusting the measuring plane to a standard horizontal position, a bubble level 403 is installed on the end face of the connector 1 facing away from the skin (i.e., the top surface visible to the operator). This bubble level 403 can indicate the current horizontal position of the connector 1 in real time and intuitively.

[0049] In the practical application of this embodiment, the operator first places the support skirt 401 on the skin next to the stoma. Then, the operator rotates the first shaping component 2 and the second shaping component 3 to close them and form the measurement area. At this time, the operator observes the horizontal bubble meter 403 at the top of the connecting seat 1 and manually fine-tunes the tilt angle of the connecting seat 1 through the ball joint structure. When the horizontal bubble meter 403 shows the bubble is centered, it indicates that the connecting seat 1 and the shaping component hinged to it are on an absolutely horizontal plane, thus ensuring that the measurement of the stoma is performed on a horizontal projection plane after eliminating the influence of the abdominal curvature, effectively avoiding projection distortion. Furthermore, the support member, as a support point of the device, effectively avoids hand tremors or fatigue caused by the operator holding the device for a long time, solving the problem of unstable measurement plane caused by relying entirely on manual feel to maintain balance in the prior art, and improving the stability of the measurement process and the reproducibility of the results.

[0050] In a preferred embodiment, the supporting skirt 401 is in the shape of a suction cup and has a large diameter to avoid problems such as slippage and swaying.

[0051] In a preferred embodiment, the ball joint structure has a certain damping, which allows the connecting seat 1 to rotate relative to the support skirt 401 when the operator applies an external force, and after the external force is removed, the static friction torque provided by the ball joint structure is greater than the gravitational torque generated by the connecting seat 1 and its connecting components (including the first shaping component 2, the second shaping component 3 and the horizontal bubble meter 403), thereby enabling the connecting seat 1 to be suspended at any adjusted angle position.

[0052] Specifically, the ball joint structure includes a ball head and a ball socket. The ball head and the ball socket are fitted with an interference fit, utilizing the elastic deformation of the material to generate a clamping force to provide damping. Alternatively, a damping pad layer (such as a rubber pad or silicone layer) can be provided between the contact interfaces of the ball head and the ball socket to increase frictional resistance. Based on this, when observing the level bubble meter 403, the operator can easily make fine adjustments by holding the connecting seat 1 with one hand. Once the bubble is centered, releasing the hand locks the position, eliminating the need for an additional locking knob and simplifying the operation.

[0053] In a preferred embodiment, the first shaping component 2 and the second shaping component 3 can be made using existing profilometry, that is, both have a number of shaping needles, and the stoma shaping measurement is performed by pushing the shaping needles.

[0054] Preferably, the end of the probing needle facing the measurement area (i.e., the end that contacts the stoma) has a smooth, hemispherical or arc-shaped contact to avoid puncturing the stoma mucosa or surrounding skin during the measurement process.

[0055] In a preferred embodiment, the plurality of forming needles includes needles of at least two different colors, such as dark and light colors, or a first color and a second color with high contrast. The needles of different colors are arranged alternately at predetermined intervals along the direction of the forming needles. Specifically, a certain number (e.g., 5, 10, or a number corresponding to a specific length unit) can be set as a group of needles of the same color, with adjacent groups of needles using different colors, thus creating a periodic color change in the overall forming needle array. This alternating arrangement structure forms a visual scale or ruler effect on the surface of the forming component, allowing the user to quickly estimate the size range of the object being measured by directly using color segmentation, or to use color boundaries as reference points for counting, thereby improving ease of use and measurement efficiency.

[0056] like Figure 4 As shown, in a preferred embodiment, to ensure the connection stability of the first shaping component 2 and the second shaping component 3 when they enclose and form the measurement area, and to avoid deformation of the measurement pattern due to loose connection or misalignment, a magnetic suction component 5 is included. The magnetic suction component 5 is embedded in the mating end faces of the free ends of the first shaping component 2 and the second shaping component 3. The magnetic suction component 5 is preferably a neodymium iron boron permanent magnet, with its N pole and S pole facing each other (or one end is a magnet and the other end is a magnetically conductive metal block). When the operator rotates the two components to bring their free ends closer together, the attraction force generated by the magnetic suction component 5 can quickly attract and lock the two together.

[0057] However, since the magnetic connection is prone to slippage under shear force, in order to prevent the two components from axially shifting in the vertical direction (i.e., along the axis of the connecting seat 1) when closed, this embodiment adds a constraint member 6 near the magnetic component 5. Specifically, a positioning cone (or positioning pin) is protruding on the free end face of the first shaping component 2, and a positioning recess adapted to the shape of the positioning cone is formed on the free end face of the second shaping component 3.

[0058] When the first shaping component 2 and the second shaping component 3 are attracted together under the action of magnetic force, the positioning cone is inserted into the positioning recess, eliminating the possibility of axial step misalignment between the two, thereby ensuring the continuity and flatness of the measurement area contour formed by the two in the vertical direction.

[0059] In a preferred embodiment, considering that there are individual differences in the height of the stoma protruding from the abdominal wall skin among different patients in clinical practice (for example, some stomas are flush with the skin surface, while others protrude outward by several centimeters), in order to ensure that the measurement area can be accurately aligned with the stoma root, and at the same time avoid the device compressing the protruding stoma tissue, the support rod 402 in this embodiment is a height-adjustable structure.

[0060] Specifically, the support rod 402 includes a first rod body and a second rod body coaxially connected. The two are connected by threads (for example, the end of the first rod body is provided with an internal threaded cylinder, the end of the second rod body is provided with a matching external threaded post, or the two are connected by an adjusting sleeve).

[0061] Based on this threaded engagement structure, the operator can continuously and smoothly adjust the axial engagement depth of the first and second rods by rotating them relative to each other, using the principle of helical transmission, thereby achieving the extension and retraction adjustment of the overall length of the support rod 402.

[0062] In practical applications, when faced with a high-protruding stoma, the operator can rotate the rod to increase the total length of the support rod 402, thereby raising the connecting seat 1 and the shaping component as a whole, leaving enough longitudinal space for the stoma and preventing the device from touching the top of the stoma; conversely, when faced with a flat or concave stoma, the operator can shorten the length of the support rod 402, lower the measurement center of gravity, and make the shaping component fit tightly against the root of the stoma.

[0063] In a preferred embodiment, a cleaning tank 7 is provided on the main body of the first shaping component 2 and the second shaping component 3.

[0064] Specifically, the cleaning groove 7 is a hollow through-hole or window structure that penetrates the upper and / or lower surfaces of the main body, and is located on the sliding path of the forming needle, that is, the cleaning groove 7 is connected to the internal sliding cavity that accommodates the forming needle.

[0065] When cleaning and disinfection of the device is required, cleaning solution, disinfectant, or high-temperature steam can directly enter the main body through the cleaning tank 7, thoroughly rinsing the surface of each prosthetic needle and the tiny gaps between adjacent needles. This effectively prevents the accumulation of blood, bodily fluids, skin flakes, or ointments in the dead corners inside the sealed needle box, ensuring that the device can achieve thorough cleaning and sterilization standards, thereby meeting the requirements for hospital infection control.

[0066] In a preferred embodiment, the outer surfaces of the free ends of the first shaping component 2 and the second shaping component 3 are provided with structures for assisting in the application of force. Specifically, this structure can be implemented as a toggle protrusion, which protrudes outward from the outer wall surface of the free end to form a solid protrusion for fingers to rest against or push and pull. The surface of the protrusion can also be further provided with anti-slip texture to increase friction. Alternatively, as another alternative, this structure can also be implemented as a finger groove, which is recessed inward from the outer wall surface of the free end, and its shape is adapted to the contour of the fingertip. By providing the above-mentioned toggle protrusion or finger groove on the outer surface of the free end, a clear and stable force fulcrum can be provided for the user when moving, adjusting or resetting the first shaping component 2 and the second shaping component 3, effectively preventing finger slippage and making the force application process easier and smoother.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
