Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a novel stool collection device. Background Technology

[0002] Stool examination is a routine clinical examination and plays an important role in the diagnosis and treatment of clinical diseases. Currently, in clinical practice, stool collection devices are usually used to collect stool samples from patients for subsequent testing.

[0003] Existing stool collection devices typically use a spoon-shaped component for sampling stool. This spoon-shaped design is generally suitable for collecting soft stools. However, for patients with diarrhea, their stools are usually unformed. The part of existing stool collectors used for sampling stool is usually a spoon structure. This spoon structure is generally suitable for collecting soft stool. However, for patients with diarrhea, their stool is usually pasty or watery, making it very inconvenient for current stool collectors to collect such pasty or watery stool. This increases the difficulty of stool collection and makes it difficult for current stool collectors to be used to collect stool of various forms.

[0004] Therefore, improving the ease of collecting soft, pasty, or watery stools with stool collectors, and reducing the difficulty of stool collection, are urgent technical problems that need to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of stool collector to address the shortcomings of current stool collectors in actual use, thereby improving the convenience of collecting soft, pasty, or watery stools and reducing the difficulty of stool collection.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A novel stool collector includes a telescopic tube assembly and a gripper assembly. The telescopic tube assembly forms a receiving cavity with an open end, and the telescopic tube assembly is used to adjust the volume of the receiving cavity. The receiving cavity is used to contain pasty or watery stool. The gripper assembly has a gripping state and a releasing state, and the gripper assembly is located at the opening of the receiving cavity. As the volume of the receiving cavity gradually decreases, the telescopic tube assembly can drive the gripper assembly to change from a gripping state to a releasing state; As the volume of the receiving cavity gradually increases, the telescopic tube assembly can drive the gripper assembly to change from a released state to a gripping state; Furthermore, when the gripper assembly changes from the released state to the gripping state, the gripper assembly can grip the feces.

[0007] As the preferred technical solution of this application, the telescopic pipe assembly includes a first pipe and a second pipe. The first pipe is a cylindrical structure with open ends, and the second pipe is a cylindrical structure with open ends and closed ends. The second pipe is sleeved on the outer wall of the first pipe.

[0008] As the preferred technical solution of this application, the novel stool collector further includes a main body and a pressing part, wherein the first pipe is connected to the main body and the second pipe is connected to the pressing part; the pressing part is connected to the main body; The pressing part has an initial state in which the gripper assembly is in a grasping state; By squeezing the pressing part, the pressing part is released from its initial state, causing the second pipe to move relative to the first pipe, so that the volume of the receiving cavity gradually decreases, and the gripper assembly changes from the gripping state to the releasing state. A spring is provided on the pressing part, and the spring is used to provide elastic force so that the pressing part returns to its initial state when no external force is applied.

[0009] As the preferred technical solution of this application, the pressing part has a corrugated pipe structure, and the length direction of the pressing part is in the same direction as the length direction of the second pipe.

[0010] As the preferred technical solution of this application, the gripper assembly includes a plurality of grippers, the grippers are rotatably connected to the end of the first pipe, the plurality of grippers are distributed around the central axis of the first pipe, the grippers are provided with gears, and the second pipe is provided with racks, the gears being used to mesh with the racks; When the second pipe moves relative to the first pipe along the length of the first pipe, the gear meshes with the rack, causing the rack to drive the gear to rotate, so that the gripper deflects relative to the central axis of the first pipe, thereby switching the gripper assembly between the gripping state and the releasing state.

[0011] As the preferred technical solution of this application, the end of the first pipe includes a base, and the gripper is rotatably connected to the base.

[0012] As a preferred technical solution of this application, a torsion spring is provided on the part of the gripper for rotatably connecting with the first pipe. The torsion spring is used to provide elastic force to give the gripper an initial state. When the gripper is in the initial state, the gripper assembly is in a gripping state.

[0013] As the preferred technical solution of this application, both the first pipe and the gripper assembly extend out of the main body; The novel stool collector also includes a cap that is detachably connected to the main body. When the cap is installed on the main body, the telescopic tube assembly and the gripper assembly are in a sealed environment.

[0014] As a preferred technical solution of this application, the novel stool collector further includes a funnel, which includes a collecting part and a connecting part. The collecting part is connected to the connecting part and is open. The collecting part is used to receive the stool discharged by the patient and allows the stool to flow from the collecting part to the connecting part. The connecting part is detachably connected to the main body. When the main body and the connecting part are connected, the telescopic tube assembly or the gripper assembly can collect the stool on the connecting part.

[0015] As the preferred technical solution of this application, the collection part is provided with a first inclined surface. When the collection part receives the patient's stool, the stool falls onto the first inclined surface. The first inclined surface is used to guide the stool to the connecting part, and the main body connected to the connecting part is arranged horizontally.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In the scheme of this application, by setting up a telescopic tube assembly and a gripper assembly, when collecting stool from a patient, the volume of the receiving cavity is gradually reduced, and the gripper assembly is driven to change from a grasping state to a releasing state. At this time, the opening of the receiving cavity and the gripper assembly extend into the stool. Then, the volume of the receiving cavity is gradually increased, and the gripper assembly is driven to change from a releasing state to a grasping state. During this process, when the stool is soft, the gripper assembly can grasp the soft stool for sampling. When the stool is pasty or watery, under the action of gradually increasing the volume of the receiving cavity, the pasty or watery stool can be gradually drawn into the receiving cavity from the opening of the receiving cavity for collection. Furthermore, the extracted stool sample can be limited by the gripper assembly or the receiving cavity, which can reduce the probability of the extracted stool sample falling off the stool collector, thereby improving the efficiency of stool sample collection. 2. Furthermore, by setting up a pressing part, pressing the pressing part causes the second pipe to move relative to the first pipe, gradually reducing the volume of the receiving cavity and causing the gripper assembly to change from a gripping state to a releasing state. During this process, the deformation of the spring gradually increases. At this time, the opening of the receiving cavity and the gripper assembly extend into the feces. Then, the external force applied to the pressing part is removed, and the spring returns to its deformation, causing the pressing part to gradually return to its initial state. During the process of the pressing part gradually returning to its initial state, the second pipe moves relative to the first pipe, gradually increasing the volume of the receiving cavity and causing the gripper assembly to gradually change from a releasing state to a gripping state. This facilitates fecal sampling and further improves the convenience of fecal sampling. 3. Furthermore, by setting a gear on the gripper and a rack on the second pipe, when the second pipe moves relative to the first pipe along the length of the first pipe, the gear and rack can mesh, and the rack can drive the gear to rotate, thereby causing the gripper to deflect relative to the central axis of the first pipe. This allows the gripper assembly to switch between a gripping state and a releasing state when the second pipe moves relative to the first pipe, thereby realizing the linkage between the volume change of the receiving cavity and the state change of the gripper assembly, further improving the convenience of sampling soft, pasty, or watery stools. 4. Furthermore, by setting up a funnel, when the patient uses the toilet for stool collection, the main body and the connecting part can be connected. Specifically, the inner wall of the main body fits onto the outer wall of the connecting part, so that the inner wall of the main body and the outer wall of the connecting part are in close contact. The patient can hold the outer wall of the main body, so that the collecting part is located below the anus. When the patient defecates, the collecting part receives the stool, and its first inclined surface acts as a guide, guiding the stool to flow to the connecting part. At this time, the operator controls the telescopic tube assembly and the gripper assembly to clamp the soft stool. The component grips or draws in paste-like or watery stool into the receiving cavity to collect a stool sample. After collection, the stool on the funnel is emptied, and the funnel is separated from the connecting part. Then, the cap is connected to the main body, so that the telescopic tube assembly, gripper assembly, and stool sample are in a sealed environment for subsequent testing. Furthermore, the funnel is made of a biodegradable and water-soluble material, so that the funnel can be thrown into the toilet after the stool sample is collected, improving the convenience of disposing of the funnel after use.

[0023] Example 1: This example provides a novel stool collector, see [link to example]. Figures 1-3 As shown, it includes a telescopic tube assembly 1 and a gripper assembly 2. The telescopic tube assembly 1 forms a receiving cavity 3 with one end open. The telescopic tube assembly 1 is used to adjust the volume of the receiving cavity 3. The receiving cavity 3 is used to contain pasty or watery stool. The gripper assembly 2 has a gripping state and a releasing state. The gripper assembly 2 is located at the opening of the receiving cavity 3. As the volume of the receiving cavity 3 gradually decreases, the telescopic tube assembly 1 can drive the gripper assembly 2 to change from the gripping state to the releasing state. As the volume of the receiving cavity 3 gradually increases, the telescopic tube assembly 1 can drive the gripper assembly 2 to change from a released state to a gripping state. Furthermore, when the gripper assembly 2 changes from the released state to the gripping state, the gripper assembly 2 can grip the feces.

[0024] In this application, by setting up a telescopic tube assembly 1 and a gripper assembly 2, when collecting stool from a patient, the volume of the receiving cavity 3 is gradually reduced, and the gripper assembly 2 is driven to change from a grasping state to a releasing state. At this time, the opening of the receiving cavity 3 and the gripper assembly 2 extend into the stool. Then, the volume of the receiving cavity 3 is gradually increased, and the gripper assembly 2 is driven to change from a releasing state to a grasping state. During this process, when the stool is soft, the gripper assembly 2 can grasp the soft stool for sampling. When the stool is pasty or watery, under the action of the gradually increasing volume of the receiving cavity 3, the pasty or watery stool can be gradually drawn into the receiving cavity 3 from the opening for collection. Furthermore, the extracted stool sample can be limited by the gripper assembly 2 or the receiving cavity 3, which can reduce the probability of the extracted stool sample falling off the stool collector, thereby improving the efficiency of stool sample collection.

[0025] In a preferred embodiment, based on the above method, the telescopic tube assembly 1 further includes a first pipe 4 and a second pipe 5. The first pipe 4 is a cylindrical structure with open ends, and the second pipe 5 is a cylindrical structure with one end open and the other end sealed. The second pipe 5 is sleeved on the outer wall of the first pipe 4.

[0026] Furthermore, by setting up a first pipe 4 and a second pipe 5, with the second pipe 5 fitted onto the outer wall of the first pipe 4, the volume of the receiving cavity 3 can be adjusted when the second pipe 5 moves relative to the first pipe 4 along the central axis of the first pipe 4, thereby increasing or decreasing the volume of the receiving cavity 3. When the open end of the receiving cavity 3 is inserted into the pasty or watery stool, the volume of the receiving cavity 3 is increased by moving the second pipe 5 relative to the first pipe 4, so that the stool can be sucked up, thereby improving the convenience of extracting pasty or watery stool.

[0027] As a preferred embodiment, based on the above method, the novel stool collector further includes a main body 6 and a pressing part 7, wherein the first pipe 4 is connected to the main body 6, and the second pipe 5 is connected to the pressing part 7; the pressing part 7 is connected to the main body 6. The pressing part 7 has an initial state in which the gripper assembly 2 is in a grasping state; By squeezing the pressing part 7, the pressing part 7 is released from its initial state, causing the second pipe 5 to move relative to the first pipe 4, so that the volume of the receiving cavity 3 gradually decreases, and the gripper assembly 2 changes from the gripping state to the releasing state. A spring 8 is provided on the pressing part 7, and the spring 8 is used to provide elastic force so that the pressing part 7 returns to its initial state when no external force is applied.

[0028] Furthermore, by setting up a pressing part 7, pressing the pressing part 7 causes the second pipe 5 to move relative to the first pipe 4, gradually reducing the volume of the receiving cavity 3 and causing the gripper assembly 2 to change from the gripping state to the releasing state. During this process, the deformation of the spring 8 gradually increases. At this time, the opening of the receiving cavity 3 and the gripper assembly 2 extend into the feces. Then, the external force applied to the pressing part 7 is removed, and the spring 8 returns to its deformation, causing the pressing part 7 to gradually return to its initial state. During the process of the pressing part 7 gradually returning to its initial state, the second pipe 5 moves relative to the first pipe 4, gradually increasing the volume of the receiving cavity 3 and causing the gripper assembly 2 to gradually change from the releasing state to the gripping state. This facilitates the sampling of feces and further improves the convenience of feces sampling. Meanwhile, in this application, one end of the spring 8 is connected to the pressing part 7, and the other end is connected to the main body, so as to facilitate the deformation of the spring 8 when the pressing part 7 is pressed.

[0029] As a preferred embodiment, based on the above method, the pressing part 7 is further provided as a corrugated tube structure, and the length direction of the pressing part 7 is in the same direction as the length direction of the second pipe 5.

[0030] Furthermore, the pressing part 7 is made into a corrugated tube structure. When the pressing part 7 is pressed, the direction of the applied force is the length direction of the pressing part 7, so that the pressing part 7 can shorten along its own length direction. When the external force applied to the pressing part 7 is removed, the pressing part 7 can extend along its own length direction, thereby improving the convenience for the operator to press the pressing part 7.

[0031] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-4 As shown, the gripper assembly 2 includes a plurality of grippers 9, which are rotatably connected to the end of the first pipe 4. The plurality of grippers 9 are distributed around the central axis of the first pipe 4. Gears 10 are provided on the grippers 9, and racks 11 are provided on the second pipe 5. The gears 10 are used to mesh with the racks 11. When the second pipe 5 moves relative to the first pipe 4 along the length direction of the first pipe 4, the gear 10 meshes with the rack 11, which enables the rack 11 to drive the gear 10 to rotate, so that the gripper 9 deflects relative to the central axis of the first pipe 4, so that the gripper assembly 2 switches between the gripping state and the releasing state.

[0032] Furthermore, by setting a gear 10 on the gripper 9 and a rack 11 on the second pipe 5, when the second pipe 5 moves relative to the first pipe 4 along the length direction of the first pipe 4, the gear 10 and the rack 11 can mesh, and the rack 11 can drive the gear 10 to rotate, thereby causing the gripper 9 to deflect relative to the central axis of the first pipe 4. This allows the gripper assembly 2 to switch between a gripping state and a releasing state when the second pipe 5 moves relative to the first pipe 4, thereby realizing the linkage between the volume change of the receiving cavity 3 and the state change of the gripper assembly 2, further improving the convenience of sampling soft, pasty, or watery stools.

[0033] As a preferred embodiment, based on the above method, the end of the first pipe 4 further includes a base 12, and the gripper 9 is rotatably connected to the base 12.

[0034] Furthermore, by setting the base 12, the gripper 9 is rotatably connected to the base 12, thereby improving the stability of the gripper 9 connected to the end of the first pipe 4. Furthermore, in this application, the second pipe 5 is provided with a plurality of notches 501, and the part on its main body 6 for connecting with the first pipe 4 and the base 12 are located in the notches 501, so that when the second pipe 5 moves relative to the first pipe 4, the part on its main body 6 for connecting with the first pipe 4 and the base 12 prevent the second pipe 5 from blocking the movement of the second pipe 5, thereby improving the smoothness of the movement of the second pipe 5 relative to the first pipe 4.

[0035] As a preferred embodiment, based on the above method, a torsion spring 13 is further provided on the part of the gripper 9 that is rotatably connected to the first pipe 4. The torsion spring 13 is used to provide elastic force to give the gripper 9 an initial state. When the gripper 9 is in the initial state, the gripper assembly 2 is in the gripping state.

[0036] Furthermore, by setting a torsion spring 13, when the gripper 9 is not subjected to external force, the torsion spring 13 keeps the gripper 9 in its initial state under its own elastic force, so that the gripper assembly 2 is in the gripping state, so that the gripper assembly 2 can grip the soft feces, thereby further improving the gripping stability.

[0037] As a preferred embodiment, based on the above method, both the first pipe 4 and the gripper assembly 2 extend out of the main body 6; The novel fecal collector also includes a cap 14, which is detachably connected to the main body 6. When the cap 14 is installed on the main body 6, the telescopic tube assembly 1 and the gripper assembly 2 are in a sealed environment.

[0038] Furthermore, both the first pipe 4 and the gripper assembly 2 extend out of the main body 6 so that when sampling feces, the end of the first pipe 4 and the gripper assembly 2 can be inserted into the feces, which further improves the convenience of collecting feces and at the same time avoids the outside of the main body 6 from being contaminated with feces.

[0039] As a preferred embodiment, based on the above method, the novel stool collector further includes a funnel 15, which includes a collection part 16 and a connecting part 17. The collection part 16 is in communication with the connecting part 17 and is open. The collection part 16 is used to receive the stool excreted by the patient and allows the stool to flow from the collection part 16 to the connecting part 17. The connecting part 17 is detachably connected to the main body 6. When the main body 6 is connected to the connecting part 17, the telescopic tube assembly 1 or the gripper assembly 2 can collect the stool on the connecting part 17.

[0040] As a preferred embodiment, based on the above method, the collection part 16 is further provided with a first inclined surface 18. When the collection part 16 receives the patient's stool, the stool falls onto the first inclined surface 18. The first inclined surface 18 is used to guide the stool to the connecting part 17, and the main body 6 connected to the connecting part 17 is arranged horizontally.

[0041] Furthermore, by setting up the funnel 15, when the patient uses the toilet to collect stool, the main body 6 can be connected to the connecting part 17. Specifically, the inner wall of the main body 6 fits onto the outer wall of the connecting part 17, so that the inner wall of the main body 6 and the outer wall of the connecting part 17 are in close contact. The patient can hold the outer wall of the main body 6, so that the collecting part 16 is located below the anus. When the patient defecates, the collecting part 16 receives the stool, and its first inclined surface 18 plays a guiding role, guiding the stool to flow to the connecting part 17. At this time, the operator controls the telescopic tube assembly 1 and the gripper assembly 2 to clamp the soft stool. The claw assembly 2 grips or draws in the receiving cavity 3 to collect a stool sample. After collection, the stool on the funnel 15 is emptied, and the funnel 15 is separated from the connecting part 17. Then, the cap 14 is connected to the main body 6, so that the telescopic tube assembly 1, the claw assembly 2, and the stool sample are in a sealed environment for subsequent testing. Furthermore, the funnel 15 is made of a biodegradable and water-soluble material, so that the funnel 15 can be thrown into the toilet after the stool sample is collected, which improves the convenience of disposing of the used funnel 15.
