Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a conventional fecal retrieval auxiliary device. Background Art

[0002] In daily medical care, a variety of specimens are collected for testing. Stool testing is a common laboratory test and plays a crucial role in diagnosing digestive system disorders (such as diarrhea and gastrointestinal bleeding). Contamination of stool specimens during sampling can lead to inaccurate test data and cause errors. Therefore, obtaining qualified, uncontaminated stool specimens is crucial for clinical diagnosis and treatment.

[0003] At present, the stool specimen collection tools provided by hospitals to patients are mostly simple specimen boxes, which require patients to hold the sampler in the specimen box and dig stool from the toilet by themselves.

[0004] There are many drawbacks in using this specimen box for stool collection, such as:

[0005] (1) When using a toilet or squat toilet, feces will slide to the bottom of the toilet bowl and mix with the accumulated water, urine or disinfectant in the toilet bowl, contaminating the feces and affecting the accuracy of the test;

[0006] (2) The stool of diarrhea patients is often thin and watery, which is difficult to collect with ordinary specimen boxes;

[0007] (3) Patients can only use the collection device in the existing stool specimen box to collect stool with their bare hands, which easily causes hand contamination. In addition, the collection rod of the existing specimen box is short, which is not convenient for collecting stool specimens deep in the toilet, making specimen collection difficult.

[0008] Therefore, in response to the above-mentioned problems, the present invention proposes an auxiliary device that can be used for both sitting and squatting toilets. Through this device, patients can successfully collect different types of stool samples (formed stool, loose stool, watery stool) without having to hold a specimen box and reach into the toilet. It can also prevent stool from being contaminated by water at the bottom of the toilet, thereby improving the qualified rate of stool sample collection, increasing the accuracy of routine stool testing, improving the patient's experience of routine stool examinations, and avoiding secondary contamination caused by direct contact between hands and the toilet or stool.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention can adjust the comfort of the patient when going to the toilet by setting a positioning component and an adjustment component. After the patient has defecated, the spring end of the pressure plate can be pressed to release the positioning of the mounting block, push the mounting block close to the channel of the mounting seat, rotate the positioning plate, and cancel the pressure applied to the spring end of the pressure plate. The compressed spring can push the pressure plate to rotate around the rotating pin so that the positioning rod is inserted into another positioning hole of the mounting block, and the mounting block is positioned again. Rotating the bevel gear 2 can drive the bevel gear 1 and the threaded rod 1 to rotate. Under the limiting effect of the slide groove, the rotating threaded rod 1 can drive the movable cylinder to move up and down along the slide groove direction of the fixed cylinder, thereby adjusting the height of the installation box, and then achieving the height adjustment of the retention rod / retention straw on the specimen box cover clamped by the clamping component, so that the patient can drive the retention rod to dig out a formed stool specimen through the digging component or can control the retention straw to absorb a water sample stool specimen through the suction component. After taking the stool sample, the rotating threaded rod can drive the movable cylinder to the top of the slide. At this time, since the limit groove is connected to the slide, the limiting effect of the slide on the movable cylinder can be released, so that the movable cylinder can move along the direction of the slide, so that the clamping component, suction component and digging component on the device are away from the channel of the mounting seat, increasing the patient's toilet space and thus improving the patient's toilet comfort.

[0026] 2. The present invention can retain samples of different types of stool by setting a digging component, a clamping component and a suction component. For formed stool, after the patient defecates, the specimen box cover equipped with a retention rod can be placed between two arc-shaped clamping blocks, and the electric push rod is controlled to drive the trapezoidal block to retract to the left, and under the limiting action of the installation frame, the two wedge-shaped blocks are driven to approach each other to achieve clamping and fixing of the specimen box cover. Starting motor 1 can drive the active gear to rotate, and then drive the driven gear to rotate, thereby driving the installation frame to rotate, and then drive the retention rod in the specimen box cover to rotate, realizing non-contact sampling, and then the specimen box is threadedly connected to the specimen box stool, and the specimen box can be removed by controlling the electric push rod to push the trapezoidal block to the right. Since the retention rod is in an inclined state after sampling, the patient can take the specimen box and tighten the specimen cover without getting his hands dirty. It not only ensures the convenience and hygiene of sampling, but also improves the willingness of patients to have stool tests. For watery stools, it is only necessary to control the extension of the electric push rod 2, and under the limiting action of the fixed rod, the tops of the two connecting rods 1 are moved away from the fixed rod, driving the middle part of the connecting rod 1 to rotate around the pin shafts installed on both sides of the fixed frame, and then the bottoms of the two connecting rods 1 are moved toward the fixed rod, thereby driving the sliding splints to approach each other, squeezing the air in the retention straw, and making its inner cavity a negative pressure state; when the bottom of the retention straw is brought into contact with the patient's watery stool through the adjustment component, the electric push rod 2 is controlled to retract, so that the retention straw can absorb the watery stool to retain the stool specimen, and then the specimen box and the specimen cover are tightened to complete the sampling.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0038] Example 1

[0039] like Figures 1 to 7 As shown, a conventional feces retention auxiliary device includes a mounting base 1, a channel is provided in the middle of the mounting base 1, a fixing component suitable for toilets and squat toilets is provided at the bottom of the mounting base 1, the top of the mounting base 1 is connected to the feces collection box 2 by sliding forward and backward, the top left rear side of the mounting base 1 is slidably connected to the mounting block 3, the top of the mounting block 3 is rotatably connected to the mounting box 4, a driven gear 5 is rotatably connected to the mounting box 4 through a fixed block and a rotating sleeve, the driven gear 5 is coaxially provided with a clamping component away from the mounting box 4, the driven gear 5 is transmission-connected to a digging component fixed in the mounting box 4, the top of the clamping component is provided with a suction component, two support plates 49 are symmetrically slidably connected to the left and right sides of the top of the mounting base 1, the top horizontal surface of the support plate 49 is flush with the top horizontal surface of the mounting base 1, and the top of the support plate 49 is provided with a fastener 50.

[0040] like Figure 4As shown, the fixing assembly includes a mounting post 32 symmetrically fixed to the bottom of the mounting seat 1 and a support post 33 inserted into the bottom of the mounting post 32. Two slides 34 are provided in the cavity of the mounting post 32, which are respectively slidably connected to the mounting post 32 and the support post 33. The slide 34 slidably connected to the mounting post 32 is the upper slide 34, and the slide 34 slidably connected to the support post 33 is the lower slide 34. Two groups of transmission links set in front and back mirror images are rotatably connected between the two slides 34. Each group of transmission links includes two symmetrical and mutually rotatably connected link rods 35. The free end of link rod 2 35 is provided with a spur gear 36. The front end bottoms of the two slides 34 are respectively meshed with the two spur gears 36 in one group of transmission links through teeth, and the rear end tops of the two slides 34 are respectively meshed with the two spur gears 36 in another group of transmission links through teeth. The side of the upper slide 34 away from link rod 2 35 is provided with a hydraulic rod 37 fixedly connected to the mounting post 32.

[0041] The mounting base 1 is placed directly above a squat toilet. The mounting base 1 can be securely supported on the ground using a fixing assembly, and the height of the mounting base 1 can be adjusted according to the patient's height. The hydraulic rod 37 is activated, stretching the upper slide 34 and moving it forward. This in turn drives the upper second link 35 of the two sets of transmission links away from the centerline of symmetry, thereby driving the support column 33 downward and the lower second link 35 of the two sets of transmission links away from the centerline of symmetry. The meshing of the spur gear 36 with the teeth on the slide 34 allows the mounting base 1 to remain securely in place at any desired height.

[0042] like Figure 1 As shown, the fixing assembly also includes an arc-shaped plate 30 symmetrically fixed to the bottom of the mounting base 1 by a spring. A guide plate 31 is provided at the bottom of the arc-shaped plate 30. When the mounting base 1 is placed on the toilet, the mounting base 1 can be firmly installed on the toilet by the restoring force of the compressed spring, and the guide plate 31 makes it suitable for toilets of different sizes, so that the device does not need to be supported on the ground to be fixed.

[0043] like Figure 3 As shown, an adjustment component is provided on the top of the mounting block 3, and the adjustment component includes a fixed cylinder 23 fixed to the top of the mounting block 3, and the bottom of the fixed cylinder 23 is rotatably engaged with a bevel gear 1 24, and the bevel gear 1 24 is engaged with a bevel gear 25 rotatably engaged with the mounting block 3, and a crank or a motor can be installed on the end of the bevel gear 25 away from the bevel gear 1 24, and a threaded rod 1 26 fixedly connected to the bevel gear 1 24 is rotatably engaged in the fixed cylinder 23, and the threaded rod 1 26 is threadedly connected to a moving cylinder 27, and the fixed cylinder 23 is provided with a slide groove 28 for the moving cylinder 27 to slide, and the mounting box 4 is fixed to the outer surface of the moving cylinder 27, and a telescopic rod can be installed between the mounting box 4 and the moving cylinder 27 to expand the adjustable range of the mounting box position.

[0044] like Figure 2As shown, two positioning holes 6 are symmetrically provided at the front and rear ends of the top of the mounting block 3. A positioning assembly that is adapted to the positioning holes 6 is rotatably engaged with the top of the mounting base 1. The positioning assembly includes a positioning plate 7 that is rotatably engaged with the top of the mounting base 1. A pressure plate 8 is hingedly connected to the top of the positioning plate 7 via a pin. Two through holes are provided at intervals on the top of the mounting base 1. A positioning rod that passes through the through holes of the positioning plate 7 and the mounting base 1 in sequence and extends to the positioning holes 6 is provided at the bottom left end of the pressure plate 8. The other end of the bottom of the pressure plate 8 is fixedly connected to the top of the positioning plate 7 via a spring. The diameter of the positioning rod near the positioning hole 6 is smaller than the diameter of the positioning rod near the pressure plate 8, which facilitates rapid positioning of the mounting block 3.

[0045] After the patient defecates, the spring end of the pressing plate 8 is pressed to release the positioning of the mounting block 3, pushing the mounting block 3 close to the channel of the mounting seat 1, rotating the positioning plate 7, and canceling the pressure applied to the spring end of the pressing plate 8. The compressed spring can push the pressing plate 8 to rotate around the rotating pin so that the positioning rod is inserted into the other positioning hole 6 of the mounting block 3, and the mounting block 3 is positioned again. Rotating the bevel gear 25 can drive the bevel gear 1 24 and the threaded rod 1 26 to rotate. Under the limiting effect of the chute 28, the rotating threaded rod 1 26 can drive the movable cylinder 27 to move up and down along the chute 28 of the fixed cylinder 23, thereby adjusting the height of the mounting box 4, and then achieving the height adjustment of the retention rod / retention straw on the specimen box cover clamped by the clamping assembly, so that the patient can drive the retention rod to dig out a formed stool specimen through the digging assembly or can control the retention straw to absorb a water sample stool specimen through the suction assembly.

[0046] like Figure 3 and Figure 5 As shown, in order to improve the patient's comfort when using the toilet, the clamping assembly, suction assembly and scooping assembly for collecting stool specimens can be stored. A limiting groove 29 for the rotation of the mobile cylinder 27 and connected to the top of the chute 28 can be provided on the outer surface of the fixed cylinder 23. After collecting the stool specimen, the rotating threaded rod 26 can drive the mobile cylinder 27 to move to the top of the chute 28. At this time, since the limiting groove 29 is connected to the chute 28, the limiting effect of the chute 28 on the mobile cylinder 27 can be released, so that the mobile cylinder 27 can move along the direction of the chute 28, so that the clamping assembly, suction assembly and scooping assembly on the device are away from the passage of the mounting seat 1, thereby increasing the patient's toilet space and improving the patient's comfort when using the toilet.

[0047] In order to improve the patient's comfort when going to the toilet in summer, the top of the mounting seat 1 is paved with a heat-conducting cool material. In order to further improve the patient's comfort when going to the toilet in winter, a constant temperature heating plate is embedded in the mounting seat 1.

[0048] like Figure 2As shown, the digging assembly includes a driving gear 14 meshing with the driven gear 5. The driving gear 14 is coaxially provided with a motor 15 fixed in the installation box 4. The driving gear 14 is rotatably connected to the installation box 4.

[0049] The clamping assembly includes a mounting frame 9 rotatably connected to the mounting box 4 and an electric push rod 10 fixed in the mounting box 4. The movable end of the electric push rod 10 is provided with a trapezoidal block 11 that penetrates the mounting frame 9 and is slidably connected to the mounting frame 9 left and right. Wedge blocks 12 are symmetrically slidably clamped on both sides of the trapezoidal block 11. The wedge blocks 12 are slidably connected to the mounting frame 9 in the front and rear directions. An arc-shaped clamping block 13 is provided on the side of the wedge block 12 away from the electric push rod 10. The movable end of the electric push rod 10 penetrates the driven gear 5 and the rotating sleeve and is movably connected to the driven gear 5 and the rotating sleeve.

[0050] After the patient has defecated, the specimen box cover with the retention rod installed can be placed between the two arc-shaped clamping blocks 13, and the electric push rod 10 can be controlled to drive the trapezoidal block 11 to retract to the left. Under the limiting action of the installation frame 9, the two wedge-shaped blocks 12 are driven to approach each other to achieve clamping and fixing of the specimen box cover. Starting the motor 15 can drive the active gear 14 to rotate, and then drive the driven gear 5 to rotate, thereby driving the installation frame 9 to rotate, and then drive the retention rod in the specimen box cover to rotate, realizing non-contact sampling, and then the specimen box and the specimen box are threadedly connected. The specimen box with the sample can be removed by controlling the electric push rod 10 to push the trapezoidal block 11 to the right. Since the retention rod is in an inclined state after sampling, the patient will not get his hands dirty when tightening the specimen box and the specimen cover, which not only ensures the convenience and hygiene of sampling, but also improves the patient's willingness to have a bowel examination.

[0051] like Figure 2 and Figure 5 As shown, the suction assembly includes a fixed frame 18 fixed to the top of the mounting frame 9, the inner bottom wall of the fixed frame 18 is provided with a fixed rod, the top of the fixed rod is provided with a limit block, and a sliding sleeve 19 is slidably connected to the fixed frame 18 through the fixed rod. The outer surface of the sliding sleeve 19 is symmetrically hinged with a connecting rod 20, and the tops of the two connecting rods 20 are jointly hinged with an electric push rod 21. The bottom of the connecting rod 20 is provided with a sliding splint 22 that is slidably engaged with the bottom of the fixed frame 18 through the connecting rod, and the middle part of the connecting rod 20 is rotatably connected to the fixed frame 18 through a pin.

[0052] The stool of diarrhea patients is mostly watery, and it is impossible to take a sample by taking a rod. After the stool specimen cover of taking a straw is fixed by the clamping assembly, the electric push rod 21 is controlled to stretch. Under the limiting effect of the fixed rod, the top of the two connecting rods 1 20 is moved in the direction away from the fixed rod, and the middle part of the connecting rod 1 20 is driven to rotate around the pins installed on both sides of the fixed frame 18, and then the bottom of the two connecting rods 1 20 is moved in the direction close to the fixed rod, thereby driving the sliding clamp 22 to approach each other, squeezing the air in the straw and making its inner cavity be a negative pressure state; when the bottom of the straw is contacted with the patient's watery stool by the adjusting assembly, the electric push rod 21 is controlled to shrink, so that the straw can be drawn into the watery stool and taken a stool specimen, and then the specimen box and the specimen cover are tightened to complete the sample. In order to prevent the stool sample in the straw from falling and causing the patient to get his hands dirty when twisting the cover under the vertical state due to the influence of gravity, the straw can be tilted by digging the assembly to avoid the occurrence of the above situation.

[0053] In addition, the height between the fixing frame 18 and the installation frame 9 can be set to be adjustable, which can be suitable for specimen boxes with different specifications installed with retention straws.

[0054] like Figure 6 As shown, an adjustment rod 38 and a guide rod 39 are rotatably connected within the cavity of the mounting base 1, each of which passes through the two ends of the feces collection box 2. The adjustment rod 38 is threadedly connected to the feces collection box 2, and the guide rod 39 is slidably connected to the feces collection box 2. By rotating the adjustment rod 38, the feces collection box 2 is driven to move forward and backward, thereby adjusting the position of the feces collection box 2. A movable plate 41 is slidably connected within the feces collection box 2. Two sets of mutually hinged connecting plates 40 are hingedly connected between the movable plate 41 and the feces collection box 2 via a connecting rod. The free ends of the two sets of connecting plates 40 are slidably connected to the feces collection box 2 and the movable plate 41 respectively via a connecting rod. A second motor 42 is provided on the inner bottom wall of the feces collection box 2. The output end of the second motor 42 is provided with a second threaded rod 43 rotatably connected to the feces collection box 2. The second threaded rod 43 is threadedly connected to a slider 44 slidably connected to the feces collection box 2. The free ends of the two sets of connecting plates 40 near the feces collection box 2 are hinged to the slider 44 via a connecting rod. Two hanging ears 45 are provided on the top of the feces collection box 2 via a spring.

[0055] The patient places the disposable feces collection bag into the feces collection box 2 and hangs it on the two hanging ears 45. The position of the feces collection box 2 can be adjusted by rotating the adjustment rod 38. The patient sits on the mounting base 1 and the patient's buttocks can press down the hanging ears 45 to firmly fix the feces collection bag on the hanging ears 45. This can prevent the feces collection bag from being separated from the hanging ears 45 due to the gravity of the feces after the patient goes to the toilet, causing the feces to not fall completely into the feces collection bag, while also ensuring that the feces specimen is not contaminated. When it is necessary to collect a sample after defecation, since the depth of the feces collection box 2 is significantly longer than the length of the collection rod / retention straw, it is inconvenient for the patient to collect the sample. The motor 42 can be started to drive the threaded rod 43 to rotate, thereby driving the slider 44 to move left and right. Under the limit of the connecting plate 40, the movable plate 41 can be driven up and down. The movable plate 41 can move upward to move the feces in the feces collection bag, thereby facilitating sampling. After sampling, the disposable feces collection bag can be directly thrown into the trash can, which is clean and hygienic.

[0056] like Figure 1 As shown, two symmetrically distributed moving blocks 46 are slidably connected in the cavity of the mounting base 1, and a urine collecting cylinder 47 is connected between the two moving blocks 46 for damping rotation. The adjusting rod 38 and the guide rod 39 pass through the two moving blocks 46 respectively. The moving block 46 is threadedly connected to the guide rod 39, and the moving block 46 is slidably connected to the adjusting rod 38. The urine collecting cylinder 47 is provided with an adjusting button 48 rotatably connected to the moving block 46 through a synchronous wheel and a synchronous belt.

[0057] When a urine sample needs to be collected, the position of the urine collecting cylinder 47 can be adjusted by rotating the guide rod 39, and the disposable urine collecting box can be placed in the urine collecting cylinder 47. The direction of the urine collecting cylinder 47 can be adjusted by the adjustment button 48 to facilitate the collection of the patient's urine sample.

[0058] Example 2

[0059] Compared with Example 1, Example 2 has the same structures as Example 1 except for the structure of the digging component.

[0060] like Figure 8 As shown, the digging assembly includes a rack 16 meshing with the driven gear 5, one end of the rack 16 is provided with an electric telescopic rod 17 fixed in the installation box 4, and the rack 16 is slidably engaged with the installation box 4.

[0061] The specific usage of the above embodiment is as follows:

[0062] The fixing assembly allows the device to be used on both sitting and squat toilets, enhancing its applicability. A disposable feces collection bag is placed in the feces collection box 2, which is further secured by the hooks 45. The position of the feces collection box 2 can be adjusted using the adjustment rod 38. When the patient sits on the mounting base 1 to use the toilet, feces completely falls into the feces collection bag, preventing the stool sample from being contaminated by urine or toilet water. After defecation, the specimen box lid, which houses the sampling tool (retention rod / retention straw), is secured between the arc-shaped clamping blocks 13 in the clamping assembly. The mounting plate is then moved and fixed in position using the positioning assembly. Motor 2 42 is activated to rotate threaded rod 2 43, which in turn drives slider 44 left and right. This, in turn, drives movable plate 41 up and down within the limits of connecting plate 40. The upward movement of movable plate 41 can move stool upward within the feces collection bag, expanding the field of view and facilitating sampling. The position of mounting box 4 is then adjusted using the adjustment assembly so that the specimen box lid is directly above feces collection box 2, allowing the retention rod / retention straw to contact the stool. Sampling is then performed using the digging assembly or suction assembly. After sampling, the specimen box and specimen lid are tightened to complete the sampling process.
