Description

Technical Field

[0001] This utility model belongs to the field of specimen sampling technology, and specifically relates to a novel stool specimen collection and separation device. Background Technology

[0002] Stool routine examination is one of the three major routine clinical examinations. Among them, fecal occult blood test is a screening indicator for diagnosing gastrointestinal bleeding of various causes and malignant tumors. However, due to the widespread use of toilet seats, while bringing comfort to patients, it has increased the difficulty of timely collection of stool samples.

[0003] Patent application number 2021223393532 discloses a novel auxiliary device for collecting fecal specimens in a toilet, including a foot pedal, a cylinder, a lever device, a stool tray, a disposable drawstring collection bag, and a toilet seat retainer. This novel toilet seat auxiliary device is rationally designed to facilitate the collection of stool samples, preventing the mixing of stool with wastewater in the toilet and fundamentally improving the sample qualification rate. It is easy to operate, avoiding direct contact between the patient and the sample, reducing patient resistance and increasing patient compliance with stool sample collection. Furthermore, it ensures timely sampling and accurate test results. The use of a stool tray raises the stool sample height, improving patient comfort and reducing the risk of falls due to bending over. The use of disposable drawstring collection bags is clean, hygienic, and inexpensive; after use, it is disposed of as medical waste, meeting hospital management requirements. However, existing stool sample collection methods easily mix urine or water with stool, causing contamination and affecting the accuracy of stool sample testing. Additionally, disposable drawstring bags are inconvenient to secure and easily deform under the weight of stool, leading to difficulties in collecting the stool. Utility Model Content

[0004] In view of this, the present invention provides a novel stool sample collection separator that can separate stool from urine, prevent urine or water from contaminating the stool and thus affecting the accuracy of sampling, facilitate reuse, improve the safety of sampling, and reduce the consumption of disposable paper or film.

[0005] The technical solution is as follows: A novel stool sample collection and separation device includes a conical stool receiving cylinder. Two symmetrical L-shaped shelves are provided on both sides of the upper end of the conical stool receiving cylinder for mounting on a toilet. The device is characterized by: an L-shaped connecting rod fixedly installed at the lower end of the conical stool receiving cylinder; a first piston cavity fixedly installed on the L-shaped connecting rod; a first piston plate slidably installed within the first piston cavity; a receiving plate slidably installed on the conical stool receiving cylinder; the first piston plate and the receiving plate being connected and fixed via a first piston rod; and a driving mechanism for moving the first piston plate on the L-shaped shelf. Operating the driving mechanism drives the receiving plate to move along the conical stool receiving cylinder via the first piston plate.

[0006] In use, the above technical solution works as follows: the operating drive mechanism moves the receiving plate along the conical stool collection tube via the first piston plate. When sampling is required, the receiving plate is pushed into the conical stool collection tube, with a gap reserved between them. Disposable paper or film is placed on the receiving plate, and the feces rest on it. Urine or water flows out through the gap between the receiving plate and the conical stool collection tube, achieving the function of separating feces and urine, preventing urine or water from contaminating the feces and affecting the accuracy of sampling. After sampling, the receiving plate is moved down along the conical stool collection tube, creating a gap between the receiving plate and the lower side of the conical stool collection tube. The feces are discharged through the gap, facilitating reuse and improving the safety of sampling, while reducing the consumption of disposable paper or film.

[0007] Preferably, the lower end of the conical toilet bowl is provided with a through hole, and the receiving plate is slidably installed in the through hole. When the receiving plate moves to the upper end of the through hole, a gap is reserved between it and the side wall of the conical toilet bowl. When the receiving plate moves to the lower end of the through hole, a gap is reserved between it and the lower end of the conical toilet bowl.

[0008] Preferably, a first annular frame is fixedly provided at the upper end of the first piston cavity, and the first piston rod slides through the first annular frame.

[0009] Preferably, the driving mechanism includes a second piston cavity fixedly mounted on one of the L-shaped shelves. The second piston cavity is connected to the first piston cavity through an air supply pipe. A second piston plate is slidably and sealed inside the second piston cavity. A second piston rod is fixedly mounted on the second piston plate and extends out of the second piston cavity. A first elastic member is provided between the second piston plate and the second piston cavity. The first elastic member pushes the second piston plate to compress the gas pressure inside the second piston cavity and the first piston cavity, thereby pushing the receiving plate through the first piston plate into the conical toilet bowl.

[0010] Preferably, a second annular frame is fixedly provided at the upper end of the second piston cavity, the second piston rod slides through the second annular frame, one end of the first elastic member is connected and fixed to the second annular frame, and the other end is connected and fixed to the second piston plate.

[0011] Preferably, the L-shaped shelf has an air delivery chamber, and the air delivery pipe is sealed and connected to the second piston chamber through the air delivery chamber.

[0012] During use, the above technical solution works as follows: the first elastic component pushes the second piston plate to compress the gas pressure in the second piston cavity and the first piston cavity, and the receiving plate is pushed by the first piston plate into the conical stool receiving cylinder to facilitate the collection of stool samples. By driving the second piston rod to move along the second piston cavity, the space in the first piston cavity and the second piston cavity is increased, thereby reducing the pressure. Under the gravity of the receiving plate, it automatically moves along the first piston cavity, which facilitates operation.

[0013] Preferably, an annular pipe is fixedly installed on the conical toilet bowl, and multiple axially evenly distributed flushing nozzles are installed on the annular pipe. Fluid is sprayed out through the flushing nozzles to clean the inner wall of the conical toilet bowl and the receiving plate. A connecting water pipe is installed on the L-shaped shelf, and the connecting water pipe is sealed and connected to the annular pipe through the infusion chamber.

[0014] Preferably, the inlet end of the connecting water pipe is connected to a tap water pipe, and a switch is provided on the connecting water pipe.

[0015] During use, the above technical solution works as follows: the tap water pipe is activated to deliver the flushing liquid into the annular pipe through the connecting water pipe and the infusion chamber, and finally sprays it out through the flushing nozzle. The flushing liquid sprayed out through the flushing nozzle cleans the inner wall of the conical toilet bowl and the receiving plate, facilitating discharge and improving cleaning performance.

[0016] Preferably, a support plate is fixedly installed on the L-shaped shelf, and a guide hole is provided on the support plate. The support plate is movably installed on a guide rod, and the guide rod is guided and installed in the guide hole. The guide rod is fixed on the U-shaped support frame, and a limit mechanism is provided between the guide rod and the support plate. The operation of the limit mechanism connects and fixes the support plate and the guide rod.

[0017] Preferably, the limiting mechanism includes multiple linearly and evenly distributed annular limiting grooves formed on the guide rod, and the limiting mechanism also includes a limiting rod slidably mounted on the support plate. An arc-shaped limiting block is fixedly provided on the limiting rod, and a second elastic component is provided between the limiting rod and the support plate. The second elastic component pushes the annular limiting block into the annular limiting groove.

[0018] During use, the above technical solution involves the support plate driving the guide rod to move or rotate, and the support plate and guide rod are connected and fixed by the limiting mechanism, which facilitates the adjustment of the position of the conical toilet bowl and is suitable for both seated and squat toilets.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] 1. The operating drive mechanism drives the receiving plate to move along the conical stool collection tube via the first piston plate. When sampling is required, the receiving plate is pushed into the conical stool collection tube with a pre-existing gap. Disposable paper or film is placed on the receiving plate, and the stool rests on the receiving plate. Urine or water flows out through the gap between the receiving plate and the conical stool collection tube, achieving the function of separating stool and urine, preventing urine or water from contaminating the stool and affecting the accuracy of sampling. After sampling, the receiving plate is driven to move down along the conical stool collection tube, creating a gap between the receiving plate and the lower side of the conical stool collection tube. The stool is discharged through the gap between the two, which facilitates reuse and improves the safety performance of sampling, while reducing the consumption of disposable paper or film.

[0021] 2. The first elastic component pushes the second piston plate to compress the gas pressure in the second piston cavity and the first piston cavity, and pushes the receiving plate through the first piston plate to insert into the conical stool receiving cylinder, which facilitates the collection of stool samples. By driving the second piston rod to move along the second piston cavity, the space in the first piston cavity and the second piston cavity is increased, thereby reducing the pressure. Under the gravity of the receiving plate, it automatically moves along the first piston cavity, which is convenient for operation.

[0022] 3. Start the tap water pipe to deliver the flushing solution into the ring pipe through the water pipe and the infusion chamber, and finally spray it out through the flushing nozzle. The flushing solution sprayed out through the flushing nozzle cleans the inner wall of the conical toilet bowl and the receiving plate, which facilitates the discharge and improves the cleaning performance.

[0023] 4. The guide rod moves or rotates through the support plate, and the support plate and guide rod are connected and fixed through the limiting mechanism, which facilitates the adjustment of the position of the conical toilet bowl.

Operating the driving mechanism drives the receiving plate 24 to move along the conical stool receiving cylinder 4 via the first piston plate 23.

[0040] The disposable paper or film is the same shape and size as the receiving plate 24.

[0041] In actual operation: The operating drive mechanism drives the receiving plate 24 to move along the conical stool receiving cylinder 4 via the first piston plate 23. When sampling is required, the receiving plate 24 is pushed into the conical stool receiving cylinder 4, with a gap reserved between them. Disposable paper or film is placed on the receiving plate 24, and the feces are placed on the receiving plate 24. Urine or water flows out through the gap between the receiving plate 24 and the conical stool receiving cylinder 4, achieving the function of separating feces and urine, preventing urine or water from contaminating the feces and affecting the accuracy of sampling. After sampling is completed, the receiving plate 24 is driven to move down along the conical stool receiving cylinder 4, so that a gap is created between the receiving plate 24 and the lower side of the conical stool receiving cylinder 4. The feces are discharged through the gap between the two, which is convenient for reuse and improves the safety performance of sampling, while reducing the consumption of disposable paper or film.

[0042] The lower end of the conical toilet bowl 4 is provided with a through hole 9. The receiving plate 24 is slidably installed in the through hole 9. When the receiving plate 24 moves to the upper end of the through hole 9, a gap will be reserved between it and the side wall of the conical toilet bowl 4. When the receiving plate 24 moves to the lower end of the through hole 9, a gap will be reserved between it and the lower end of the conical toilet bowl 4.

A second piston rod 25 is fixedly mounted on the second piston plate 26 and extends out of the second piston chamber 12. A first elastic member 27 is provided between the second piston plate 26 and the second piston chamber 12. The first elastic member 27 pushes the second piston plate 26 to compress the gas pressure in the second piston chamber 12 and the first piston chamber 7, thereby pushing the receiving plate 24 through the first piston plate 23 into the conical toilet bowl 4.

[0045] A second annular frame 13 is fixedly provided at the upper end of the second piston cavity 12. The second piston rod 25 slides through the second annular frame 13.

[0047] An air delivery chamber 14 is provided on the L-shaped shelf, and the air delivery pipe 8 is sealed and connected to the second piston chamber 12 through the air delivery chamber 14.

[0048] In actual operation: the first elastic component 27 pushes the second piston plate 26 to squeeze the gas in the second piston cavity 12 and the first piston cavity 7, and the first piston plate 23 pushes the receiving plate 24 to be inserted into the conical stool receiving cylinder 4. At this time, a gap is reserved between the receiving plate 24 and the conical stool receiving cylinder 4 to facilitate the receiving of stool samples. By driving the second piston rod 25 to move along the second piston cavity 12, the space in the first piston cavity 7 and the second piston cavity 12 is increased, thereby reducing the pressure. Under the gravity of the receiving plate 24, it automatically moves along the first piston cavity 7. At this time, the upper end face of the receiving plate 24 is away from the lower end face of the conical stool receiving cylinder 4, and the stool is discharged through the gap between the upper end face of the receiving plate 24 and the lower end face of the conical stool receiving cylinder 4. Example

Flushing liquid is sprayed out through the flushing nozzles 16 to clean the inner wall of the conical toilet bowl 4 and the receiving plate 24. A connecting water pipe 18 is installed on the L-shaped shelf. The connecting water pipe 18 is sealed and connected to the annular pipe 15 through the infusion chamber 17.

[0050] Specifically: the flushing nozzle 16 is inclined toward the through hole 9 in the center of the conical toilet bowl 4, and an infusion chamber 17 is provided on the L-shaped shelf.

[0051] The inlet end of the water pipe 18 is connected to the tap water pipe, and a switch is installed on the water pipe 18.

[0052] In actual operation: the tap water pipe is started and the flushing liquid is transported to the annular pipe 15 through the water pipe 18 and the infusion chamber 17. Finally, it is sprayed out through the flushing nozzle 16. The flushing liquid sprayed out through the flushing nozzle 16 cleans the inner wall of the conical toilet bowl 4 and the receiving plate 24, which facilitates the discharge of the waste and improves the cleaning performance. Example

[0053] Based on Embodiment 2, a support plate 11 is fixedly installed on the L-shaped shelf. A guide hole 19 is provided on the support plate 11. The support plate 11 is movably installed on the guide rod 2. The guide rod 2 is guided and installed in the guide hole 19. The guide rod 2 is fixed on the U-shaped support frame 1. A limit mechanism is provided between the guide rod 2 and the support plate 11. The operation of the limit mechanism connects and fixes the support plate 11 and the guide rod 2.

[0054] The limiting mechanism includes multiple linearly and evenly distributed annular limiting grooves 3 on the guide rod 2. The limiting mechanism also includes a limiting rod 28 slidably mounted on the support plate 11. An arc-shaped limiting block 32 is fixedly installed on the limiting rod 28. A second elastic component 30 is provided between the limiting rod 28 and the support plate 11. The second elastic component 30 pushes the annular limiting block into the annular limiting groove 3.

[0055] Specifically: the support plate 11 has an arc-shaped groove 20 and a sliding cavity 21, which are connected. The end of the sliding cavity 21 is provided with a third annular frame. A third piston plate 29 is fixedly provided on the limiting rod 28. The second elastic component 30 is a clamping spring, which is movably fitted on the limiting rod 28. One end of the clamping spring is connected and fixed to the third annular frame, and the other end is connected and fixed to the third piston plate 29. The limiting rod 28 slides through the third annular frame. An arc-shaped sliding block 31 is fixedly provided on the other end of the limiting rod 28. An arc-shaped limiting block 32 is fixed on the arc-shaped sliding block 31, and multiple arc-shaped limiting blocks 32 are linearly and evenly distributed on the arc-shaped sliding block 31 and correspond to multiple arc-shaped limiting grooves. The arc-shaped sliding block 31 is slidably installed in the arc-shaped groove 20.

[0056] Pull rings 33 are provided at the ends of the first piston rod 22, the second piston rod 25 and the limiting rod 28. The U-shaped support frame 1 is provided with mounting holes, which facilitates connecting and fixing the U-shaped support frame 1 to the fixed object by passing bolts through the mounting holes.

[0057] In actual operation: the operating pull ring 33 drives the limiting rod 28 to move along the sliding cavity 21, which in turn drives the third piston plate 29 and the arc-shaped sliding block 31 to move. The arc-shaped sliding block 31 drives the arc-shaped limiting block 32 to retract into the arc-shaped groove 20 and compress the clamping spring. The support plate 11 drives the conical toilet bowl 4 to rotate and move up and down along the guide rod 2, thereby adjusting the position of the conical toilet bowl 4. Then, the external force on the limiting rod 28 is removed, and the clamping spring pushes the arc-shaped limiting block 32 into the arc-shaped limiting groove, connecting and fixing the support plate 11 and the guide rod 2. This facilitates the adjustment of the position of the conical toilet bowl 4 and is suitable for use with sitting or squatting toilets.

[0058] The working principle of this utility model is as follows: The first elastic component 27 pushes the second piston plate 26 to compress the gas in the second piston cavity 12 and the first piston cavity 7. The first piston plate 23 pushes the receiving plate 24 into the conical stool receiving cylinder 4. At this time, a gap is reserved between the receiving plate 24 and the conical stool receiving cylinder 4 to facilitate the collection of stool samples. By driving the second piston rod 25 to move along the second piston cavity 12, the space in the first piston cavity 7 and the second piston cavity 12 increases, thereby reducing the pressure. Under the gravity of the receiving plate 24, it automatically moves along the first piston cavity 7. At this time, the upper end face of the receiving plate 24 is away from the lower end face of the conical stool receiving cylinder 4, and the stool is discharged through the gap between the upper end face of the receiving plate 24 and the lower end face of the conical stool receiving cylinder 4.
