Description

Technical Field

[0001] This utility model relates to the field of medical testing device technology, and in particular to a fecal collection device. Background Technology

[0002] Fecal sample testing, a routine technique in modern medicine for disease diagnosis, has become an effective means of early screening for many diseases. Existing technologies include devices for collecting fecal samples. These devices are fixed to toilet bowl structures such as toilet seats or saddles using a support structure. This support structure is connected to a load-bearing structure, which collects the feces and prevents them from falling into the toilet bowl. The user then samples the feces from the load-bearing structure and, after sampling, removes the support structure from the toilet seat and flushes the entire device down the drain. While these devices are made of water-soluble materials, their large size often causes blockages in the toilet's drainpipe. Therefore, minimizing the size of the device that falls into the water while ensuring sufficient load-bearing capacity and surface area is a pressing problem in this field. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect in the prior art that the fecal treatment device cannot be separated, resulting in the part falling into the water being too large and easily causing blockage, and to provide a fecal collection device.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A fecal collection device includes a support structure and a load-bearing structure. The load-bearing structure is used to receive feces. The fecal collection device also includes a connecting part. The load-bearing structure is connected to the support structure through the connecting part. A breakable area is provided at the connection between the connecting part and the support structure to allow the load-bearing structure to detach from the support structure.

[0006] The support structure and the load-bearing structure are connected by a connecting part. The connection between the connecting part and the support structure is provided with a breakable area. After sampling, the user can disconnect the collection device from the breakable area to separate the support structure and the load-bearing structure. This means that the support structure used to fix the feces collection device does not need to be put into the drain pipe of the toilet or other equipment together with the load-bearing structure, thereby reducing the volume of the device put into the water and avoiding blockage of the drain pipe of the toilet or other external equipment.

[0007] Preferably, the connecting portion surrounds the load-bearing structure, and the fragile area is arranged on the outer periphery of the connecting portion;

[0008] The fecal collection device further includes a traction unit, which is connected to the connecting unit and extends outward.

[0009] The connecting part surrounds the load-bearing structure, and the breakable area is arranged on the outer periphery of the connecting part. The load-bearing structure and the connecting part extend outward under the pull of the traction part. This collection device will separate in the breakable area, that is, on the outer periphery of the connecting part. The addition of the traction part and this arrangement allows the user to separate the support structure and the load-bearing structure in a more effortless and hygienic way.

[0010] Preferably, the number of traction parts is at least two, one of which is connected to the left side of the connecting part and extends to the right, and the other is connected to the right side of the connecting part and extends to the left. The two traction parts are staggered in the height direction from the area of ​​the bearing structure used to bear feces.

[0011] Using two or more traction components respectively set on both sides of the connection, and with the traction components staggered from the load-bearing area in the height direction, this layout is conducive to applying traction force evenly, making the entire device more uniformly stressed and running more smoothly during traction, improving traction efficiency and reliability, so that the load-bearing structure and the support structure can be better separated.

[0012] Preferably, at least a portion of the traction part is made of a water-soluble material.

[0013] By making a portion of the traction unit a water-soluble material, the traction unit may be contaminated by fecal samples containing pathogens during the sampling process. After the user has finished sampling, this portion of the traction unit can be flushed away with water, reducing the health risk to others.

[0014] Preferably, the traction part is a pull rope, which includes a first pull rope located outside the fragile area and a second pull rope located inside the fragile area. The second pull rope is made of a water-soluble material, and the tensile strength of the first pull rope is higher than that of the second pull rope. The first pull rope and the second pull rope are connected by a break point.

[0015] In this configuration, the traction unit consists of a common rope structure, which is inexpensive to manufacture. The portion of the traction unit located inside the fragile area is easily contaminated by the sample. By making the inner part, i.e., the second rope, a water-soluble material, it can be directly washed away by water along with the connecting part and the load-bearing structure. At the same time, water-soluble materials generally have lower tensile strength. Therefore, the tensile strength of the first rope is set to be higher than that of the second rope, so that the traction unit as a whole has better traction performance.

[0016] Preferably, the first pull rope and the second pull rope are connected by hot melt adhesive to form the breakable point at the connection;

[0017] And / or, the traction part further includes a buckle, the buckle being fixed to the support structure, and the first pull rope being bound in the buckle;

[0018] And / or, the first pull rope and the second pull rope are composed of the same number of multiple wires, wherein the wires in the second pull rope are separated and each is connected to the upper and lower sides of the connecting part.

[0019] The application of hot melt adhesive is relatively simple. Simply heat the adhesive to a molten state, apply it to the connection point between the outer pull rope and the folding structure, and allow it to cool and solidify to complete the connection. This method requires no complex equipment or processes, enabling rapid installation of the pull rope, improving production efficiency, and making it suitable for large-scale production. Furthermore, the rapid curing properties of hot melt adhesive reduce waiting time and speed up the assembly process during device assembly.

[0020] Setting a buckle to constrain the first pull rope and fix it to the support structure can constrain the traction direction of the traction part, so that the traction force on both sides can be applied symmetrically, making the force on the fragile area more uniform and preventing the load-bearing structure from overturning during the separation of the load-bearing structure from the support structure.

[0021] The multiple wires in the second pull rope are connected to the upper and lower sides of the connector, ensuring that the connection is evenly stressed when tension is applied. This multi-wire pull rope structure also offers higher strength and flexibility compared to a single wire.

[0022] Preferably, the connecting part is provided with a foldable area, which extends in the front-back direction and is located between the connection positions of the two traction parts and the connecting part;

[0023] When the two traction parts pull the connecting part outward, the easily bent area of ​​the connecting part bends and causes the load-bearing structure to close.

[0024] A foldable area is provided on the connecting part, so that when the traction part extends outward, the connecting part will fold over the foldable area and drive the supporting structure to close, thereby allowing the supporting structure to wrap the collected fecal sample, so as to ensure that the device maintains the hygiene of the surrounding environment during separation.

[0025] Preferably, the two sides of the connecting portion are higher than the easily folded area;

[0026] And / or, the connecting part is an integral elliptical ring structure, and the width of the easily foldable area is smaller than the width of the two sides of the connecting part.

[0027] By setting the two sides of the connecting part higher than the center of the connecting part, it can be ensured that the connecting part folds upward rather than downward when the user pulls the rope. This allows the connecting part to move the supporting structure to wrap around the collected fecal sample, ensuring that the device maintains the hygiene of the surrounding environment during separation.

[0028] By setting the width of the foldable area to be smaller than the width of the left and right sides of the connecting part, the folding function can be achieved in the case of an integrated design, without the need for a separate hinge device, which reduces manufacturing costs and improves the reliability of the connecting part.

[0029] Preferably, the shape of the support structure includes a ring;

[0030] And / or, the support structure includes a mesh structure.

[0031] The additional outer structure increases the area of ​​the supporting structure protected from contamination. The mesh structure better achieves dry and wet separation. In special circumstances, urine may inevitably cause local contamination, or diarrhea may lead to overflowing feces. The mesh structure can leak excess liquid, ensuring that the area around the supporting structure is also protected from contamination by excess liquid. It can also increase the dry-to-wet ratio of diarrheal feces, making it easier for users to take samples.

[0032] Preferably, the supporting structure includes a sterile cloth layer and an activated carbon fiber layer, with the sterile cloth layer located above the activated carbon fiber layer.

[0033] As a primary filtration layer, the sterile cloth, with its fine fiber structure, effectively intercepts various solid impurities in feces and allows excess liquid to leak out, preventing contamination of the subject's feces by urine or other liquid substances. Furthermore, the underlying activated carbon fiber layer possesses a well-developed microporous structure and a large specific surface area, exhibiting superior adsorption capacity for odorous gases and fine particles. It can adsorb harmful gases such as ammonia and hydrogen sulfide produced during fecal decomposition, preventing odor emissions and significantly reducing the inconvenience of odors for users during subsequent sampling.

[0034] The positive and progressive effects of this utility model are as follows: the support structure and the load-bearing structure are connected by a connecting part, and the connection between the connecting part and the support structure is provided with a breakable area. After sampling, the user can separate the support structure and the load-bearing structure by disconnecting the collection device from the breakable area. The support structure does not need to fall into the water, thereby reducing the volume of the device that falls into the water and avoiding blockage of external devices such as toilets.

[0065] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0066] Example 1

[0067] like Figures 1-3 As shown, this embodiment provides a fecal collection device 1, which includes a support structure 10 and a load-bearing structure 20. The load-bearing structure 20 is used to receive feces. The fecal collection device 1 also includes a connecting part 30. The load-bearing structure 20 is connected to the support structure 10 through the connecting part 30. A breakable area 40 is provided at the connection between the connecting part 30 and the support structure 10 so that the load-bearing structure 20 can be detached from the support structure 10.

[0068] The support structure 10 and the load-bearing structure 20 are connected by a connecting part 30. A breakable area 40 is provided at the connection point between the connecting part 30 and the support structure 10. After sampling, the user can disconnect the feces collection device 1 from the breakable area 40 to separate the support structure 10 and the load-bearing structure 20. The support structure 10 does not need to fall into the water, thus reducing the volume of the device that falls into the water and preventing blockage of external devices such as the toilet. In this embodiment, an additional traction part 50 is used to apply traction force to the breakable area 40. In other embodiments, the user can also directly apply force to the breakable area 40 to detach the load-bearing structure 20 from the support structure 10. In this embodiment, the connecting part 30 is an integral rigid cardboard frame structure. When the connecting part 30 and the load-bearing structure 20 fall into the water together, the connecting part 30 can soften or even break upon contact with water, thus preventing blockage of the toilet 70.

[0069] like Figures 1-3 As shown, in the fecal collection device 1 provided in this embodiment, the connecting part 30 is annular in shape and surrounds the supporting structure 20. The easily breakable area 40 is evenly arranged on the outer periphery of the connecting part 30, so as to realize the reliable connection between the connecting part 30 and the supporting structure 20 during use.

[0070] In this embodiment, the fecal collection device 1 further includes a traction part 50, which is connected to the connecting part 30 and extends further outward. In this arrangement, the connecting part 30 surrounds the supporting structure 20, and the breakable area 40 is arranged on the outer periphery of the connecting part 30. The supporting structure 20 and the connecting part 30 extend outward under the influence of the traction part 50. The collection device separates at the breakable area 40, i.e., the outer periphery of the connecting part 30. The addition of the traction part 50 and this arrangement allow the user to separate the supporting structure 10 and the supporting structure 20 in a more effortless and hygienic manner. In this embodiment, two traction parts 50 are provided. In other embodiments, a single traction part 50 can be used to apply force to the breakable area 40.

[0071] like Figures 1-3 As shown, in the fecal collection device 1 provided in this embodiment, there are two traction parts 50. One traction part 50 is connected to the left side of the connecting part 30 and extends to the right, and the other traction part 50 is connected to the right side of the connecting part 30 and extends to the left. The two traction parts 50 are staggered in height from the area of ​​the bearing structure 20 used to bear feces.

[0072] Two traction units 50 are respectively disposed on both sides 32 of the connecting part, and the traction units 50 are staggered with the bearing area in the height direction. This layout is conducive to applying traction force evenly, making the entire device more uniformly stressed and running more smoothly during traction, thus improving traction efficiency and reliability. In other embodiments, the number of traction units 50 can be set to three or more. By setting the traction units 50 at different positions of the connecting part 30, the entire device can be subjected to more uniform force.

[0073] In this embodiment, the second pull rope 52 of the traction part 50 in the feces collection device 1 is made of water-soluble material.

[0074] By using a portion of the traction unit 50 as a water-soluble material, the traction unit 50 may be contaminated by fecal samples containing pathogens during sampling. After sampling, the user can flush this portion of the traction unit 50 away with water, reducing the health risk to others. In other embodiments, more or all of the traction unit 50 may be made of a water-soluble material.

[0075] like Figures 1-3As shown, in this embodiment, the traction part 50 of the fecal collection device 1 is a pull rope. The pull rope includes a first pull rope 51 located outside the fragile area 40 and a second pull rope 52 located inside the fragile area 40. The second pull rope 52 is made of a water-soluble material. The tensile strength of the first pull rope 51 is higher than that of the second pull rope 52. The first pull rope 51 and the second pull rope 52 are connected by a break point 53. In this configuration, the traction part 50 is composed of a common pull rope structure, which is inexpensive to manufacture. The part of the traction part 50 located inside the fragile area 40 is easily contaminated by the sample. Making the inner part, i.e., the second pull rope 52, a water-soluble material allows it to be directly washed away by water along with the connecting part 30 and the supporting structure 20. At the same time, the tensile strength of water-soluble materials is usually low. Therefore, the tensile strength of the first pull rope 51 is set to be higher than that of the second pull rope 52 so that the traction part 50 as a whole has better traction performance. Specifically, in this embodiment, the first pull rope 51 is made of cotton thread, and the second pull rope 52 is made of non-woven fabric. The first pull rope 51 and the second pull rope 52 are connected by heat fusion. In other embodiments, the first pull rope 51 can be made of other materials with high tensile strength, which can also meet the traction performance requirements of the traction unit 50. This part belongs to the prior art in this field and will not be described in detail here.

[0076] like Figures 1-3 As shown, in this embodiment, the first pull rope 51 and the second pull rope 52 in the feces collection device 1 are connected by hot melt adhesive to form a breakable point 53 at the connection. The traction part 50 also includes a buckle 54, which is fixed to the support structure 10, and the first pull rope 51 is bound in the buckle 54. Both the first pull rope 51 and the second pull rope 52 are composed of two wires, and the two wires in the second pull rope 52 are separate and each is connected to the upper and lower sides of the connecting part 30.

[0077] The application of hot melt adhesive is relatively simple. Simply heat the adhesive to a molten state, apply it to the connection point 30 between the outer pull rope and the folding structure, and allow it to cool and solidify to complete the connection. This method requires no complex equipment or processes, enabling rapid installation of the pull rope, improving production efficiency, and making it suitable for large-scale production. Furthermore, the rapid curing characteristic of the hot melt adhesive reduces waiting time and speeds up the assembly process. Setting a buckle 54 to constrain the first pull rope 51 and fix it to the support structure 10 constrains the traction direction of the traction part 50, allowing the traction force on both sides to be applied symmetrically. This results in a more even stress distribution on the fragile area 40, preventing the load-bearing structure 20 from overturning during separation from the support structure 10.

[0078] The multiple wires in the second pull rope 52 are connected to the upper and lower sides of the connecting part 30, so that when tension is applied to the pull rope, the connecting part 30 is evenly stressed. The pull rope structure composed of multiple wires also has higher strength and flexibility compared to a single wire.

[0079] like Figures 1-3 As shown, the connecting part 30 is provided with a flexible area 31, which extends in the front-to-back direction and is located between the connection positions of the two traction parts 50 and the connecting part 30. When the two traction parts 50 pull the connecting part 30 outward, the flexible area 31 of the connecting part 30 bends and drives the load-bearing structure 20 to close.

[0080] A foldable area 31 is provided on the connecting part 30, so that when the traction part 50 extends outward, the connecting part 30 will fold over the foldable area 31 and drive the supporting structure 20 to close, thereby allowing the supporting structure 20 to wrap around the collected fecal sample to ensure that the device maintains the hygiene of the surrounding environment during separation.

[0081] like Figures 1-3 As shown, the two sides 32 of the connecting part are higher than the easily folded area 31. The connecting part 30 is an integral elliptical ring structure, and the width of the easily folded area 31 is smaller than the width of the two sides 32 of the connecting part.

[0082] By setting the two sides 32 of the connecting part higher than the center of the connecting part 30, it can be ensured that the connecting part 30 folds upward rather than downward when the user pulls the rope, so that the connecting part 30 drives the supporting structure 20 to wrap around the fecal sample collected in the residence, thereby ensuring that the device maintains the hygiene of the surrounding environment when performing separation.

[0083] By setting the width of the foldable area 31 to be smaller than the width of the left and right sides of the connecting part 30, the folding function can be achieved in a one-piece design without the need for a separate hinge device, reducing manufacturing costs and improving the reliability of the connecting part 30. Of course, in other embodiments, common hinge devices can be used to achieve the folding function. Such common hinge devices are prior art in this field and will not be described in detail here. In this embodiment, when the fecal collection device 1 is fixed to the toilet 70 and before the device is separated, the supporting structure 20 maintains a certain distance from the water surface in the toilet 70 to ensure that the fecal sample is not contaminated by the liquid in the toilet 70 before the device is separated.

[0084] like Figures 1-3 As shown, in this embodiment, the support structure 10 of the feces collection device 1 has an annular shape and includes a mesh structure 11.

[0085] In this embodiment, the shape and size of the support structure 10 correspond to the opening of the toilet seat 71. Specifically, the support structure 10 is designed to be annular to better fit the shape of the opening of the toilet seat 71. The additional mesh structure 11 increases the area of ​​the support structure 10 that is protected from contamination. The mesh structure 11 also facilitates better separation of wet and dry substances. In special circumstances, urine may inevitably cause localized contamination, or diarrhea may lead to excessive fecal discharge. The mesh structure 11 allows excess liquid to leak out, ensuring that the area around the supporting structure 20 is also protected from contamination by excess liquid. Furthermore, it increases the ratio of wet to dry feces, making it easier for the user to take samples. In other embodiments, the shape of the support structure 10 can be designed to correspond to the shape of the opening of the external device.

[0086] In this embodiment, the supporting structure 20 in the fecal collection device 1 includes a sterile cloth layer and an activated carbon fiber layer (not shown in the figure), with the sterile cloth layer located above the activated carbon fiber layer.

[0087] The sterile cloth layer, acting as the primary filtration layer, effectively intercepts various solid impurities in feces and allows excess liquid to leak out thanks to its fine fiber structure, preventing contamination of the subject's feces by urine or other liquid substances. Furthermore, the underlying activated carbon fiber layer possesses a well-developed microporous structure and a large specific surface area, exhibiting superior adsorption capacity for odorous gases and fine particles. It can adsorb harmful gases such as ammonia and hydrogen sulfide produced during fecal decomposition, preventing odor emissions and significantly reducing the inconvenience of odors for users during subsequent sampling.

[0088] like Figures 1-3 As shown, the fecal collection device 1 has four fixing structures 60 around its perimeter. Specifically, in this embodiment, the fixing structure 60 is a Velcro structure, which allows the user to fix the fecal collection device 1 to the toilet seat 71. The fecal collection device 1 also includes a sealing patch (not shown in the figure). Before using the fecal collection device 1, the sealing patch covers the supporting structure 20 to ensure that the supporting structure 20 maintains a clean environment that isolates other bacteria or impurities. When needed, the user can remove the sealing patch to collect fecal samples.

[0089] Example 2

[0090] Unlike Embodiment 1, in Embodiment 2, the fecal collection device 1 is fixed to the toilet seat 72 by four sets of fixing structures 60 of a different form. Each set of fixing structures 60 includes a rubber suction cup 61, a positioning post 62, a conical barb 63, a connecting piece 64, and a tearable patch 65. The rubber suction cup 61 is attached to the surface of the toilet seat 72 at a position that matches the bottom groove of the toilet ring 71. The positioning post 62 and the conical barb 63 are located on the back of the rubber suction cup 61 with the conical barb 63 facing upward. Four tearable patches 65 are located on the side of the fecal collection device 1 corresponding to the position of the rubber suction cup 61 and are attached to the corresponding connecting pieces 64. The user can pass the connecting piece 64 down through the slot 640 on it through the barb 63 and the positioning post 62, thereby unfolding the fecal collection device 1 on the toilet seat 72 to complete the installation.
