Description

Technical Field

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

[0002] In daily medical treatment, various specimens need to be collected for testing. Among them, stool routine is a common laboratory test method, which is of great significance for the diagnosis of patients with digestive system diseases (such as diarrhea, gastrointestinal bleeding, etc.). If the stool specimen is contaminated during the sampling process, it will lead to inaccurate test data and cause test errors. Therefore, retaining qualified and uncontaminated stool specimens is of great significance for clinical diagnosis and treatment.

[0003] At present, the stool specimen collection tools provided by various hospitals for 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 defects in using this specimen box for stool collection, such as: (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; (2) The stool of diarrhea patients is often thin and watery, which is difficult to collect with ordinary specimen boxes; (3) Patients can only use the collection device in the existing stool specimen box to collect stool with their bare hands, which can easily cause 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 it difficult to collect specimens.

[0005] Therefore, in order to solve the above-mentioned problem, 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 specimens (formed stool, loose stool, watery stool) without having to hold a specimen box and reach into the toilet bowl. The stool can also be prevented from being contaminated by water at the bottom of the toilet bowl, 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 bowl or stool.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 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. The rotating 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 moving 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 adjusting the height 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 the formed stool specimen through the digging component or the patient can control the retention straw to absorb the water sample stool specimen through the suction component. After taking the stool sample, the rotating threaded rod can drive the moving cylinder to the top of the slide groove. At this time, since the limit groove is connected to the slide groove, the limiting effect of the slide groove on the moving cylinder can be released, so that the moving cylinder can move along the direction of the slide groove, so that the clamping component, suction component and digging component on the device are away from the channel of the mounting seat, thereby increasing the patient's toilet space and improving the patient's toilet comfort.

[0021] 2. The present invention can retain samples of different types of stool by providing a scooping component, a clamping component and a suction component. For formed stool, after the patient defecates, the specimen box cover equipped with a retaining rod can be placed between two arc-shaped clamping blocks, and the electric push rod can be controlled to drive the trapezoidal block to retract to the left, and the two wedge-shaped blocks can be driven closer to each other under the limiting effect of the installation frame 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 retaining rod in the specimen box cover to rotate, so as to achieve non-contact sampling, and then the specimen box and the specimen box stool are threadedly connected, and the specimen box for retaining samples can be removed by controlling the electric push rod 1 to push the trapezoidal block to the right. Since the retaining 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 examination. For watery stool, 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 shaft 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 in 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.

[0026] like Figure 4As shown, the fixing assembly includes a mounting column 32 symmetrically fixed to the bottom of the mounting seat 1 and a support column 33 inserted into the bottom of the mounting column 32. Two slide plates 34 are provided in the cavity of the mounting column 32, which are slidably connected to the mounting column 32 and the support column 33 respectively. The slide plate 34 slidably connected to the mounting column 32 is an upper slide plate 34, and the slide plate 34 slidably connected to the support column 33 is a lower slide plate 34. Two groups of transmission connecting rods arranged in front and back mirror images are rotatably connected between the two slide plates 34. Each group of transmission connecting rods includes two symmetrical and mutually rotatably connected connecting rods 35. The free end of the connecting rod 35 is provided with a spur gear 36. The front end bottoms of the two slide plates 34 are respectively meshed with the two spur gears 36 in one group of transmission connecting rods through teeth, and the rear end tops of the two slide plates 34 are respectively meshed with the two spur gears 36 in another group of transmission connecting rods through teeth. The side of the upper slide plate 34 away from the connecting rod 35 is provided with a hydraulic rod 37 fixedly connected to the mounting column 32.

[0027] The mounting base 1 is placed directly above the squat toilet / squat toilet, and the device can be firmly supported on the ground by the fixing assembly, and the height of the mounting base 1 can be adjusted according to the height of the patient. The hydraulic rod 37 is activated, and the upper slide plate 34 is stretched to move forward, and the upper connecting rod 35 of the two sets of transmission connecting rods is driven to move away from the symmetry center line, thereby driving the support column 33 to move downward, and the lower connecting rod 35 of the two sets of transmission connecting rods is also moved away from the symmetry center line, and the spur gear 36 is meshed with the teeth on the slide plate 34 to enable the mounting base 1 to stay firmly at any suitable height.

[0028] like Figure 1 As shown, the fixing assembly also includes an arc plate 30 symmetrically fixed to the bottom of the mounting base 1 by a spring, and a guide plate 31 is provided at the bottom of the arc 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 can be fixed without being supported on the ground.

[0029] 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 fixedly mounted on the top of the mounting block 3, a bevel gear 24 is rotatably engaged at the bottom of the fixed cylinder 23, and the bevel gear 24 is meshed 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 24, and a threaded rod 26 fixedly connected to the bevel gear 24 is rotatably engaged in the fixed cylinder 23, and the threaded rod 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 fixedly mounted on 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.

[0030] like Figure 2As shown, two positioning holes 6 are symmetrically arranged at the front and rear ends of the top of the mounting block 3, and a positioning assembly adapted to the positioning hole 6 is rotatably connected to the top of the mounting seat 1, and the positioning assembly includes a positioning plate 7 rotatably connected to the top of the mounting seat 1, and a pressing plate 8 is hinged on the top of the positioning plate 7 through a pin shaft, and two through holes are arranged at intervals on the top of the mounting seat 1, and a positioning rod is arranged at the bottom left end of the pressing plate 8, which passes through the through holes of the positioning plate 7 and the mounting seat 1 in sequence and extends to the positioning hole 6, and the other end of the bottom of the pressing plate 8 is fixedly connected to the top of the positioning plate 7 through a spring. The diameter of the positioning rod near the positioning hole 6 is smaller than the diameter of the positioning rod near the pressing plate 8, so as to facilitate the rapid positioning of the mounting block 3.

[0031] After the patient has defecated, the spring end of the pressing plate 8 is pressed to release the positioning of the mounting block 3, push the mounting block 3 close to the channel of the mounting seat 1, rotate the positioning plate 7, cancel the pressure applied to the spring end of the pressing plate 8, and the compressed spring can push the pressing plate 8 to rotate around the rotating pin so that the positioning rod is inserted into another positioning hole 6 of the mounting block 3, and the mounting block 3 is positioned again. The rotation of the bevel gear 25 can drive the bevel gear 1 24 and the threaded rod 1 26 to rotate, and under the limiting effect of the slide groove 28, the rotating threaded rod 1 26 can drive the moving cylinder 27 to move up and down along the slide groove 28 of the fixed cylinder 23, thereby adjusting the height of the mounting box 4, and then adjusting the height 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 the formed stool specimen through the digging assembly or the patient can control the retention straw to absorb the water sample stool specimen through the suction assembly.

[0032] like Figure 3 and Figure 5 As shown, in order to improve the comfort of the patient's toilet, the clamping assembly, suction assembly and digging assembly for collecting stool specimens can be stored, and a limit groove 29 for the mobile cylinder 27 to rotate and connected to the top of the slide 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 slide 28. At this time, since the limit groove 29 is connected to the slide 28, the limit effect of the slide 28 on the mobile cylinder 27 can be released, so that the mobile cylinder 27 moves along the direction of the slide 28, so that the clamping assembly, suction assembly and digging assembly on the device are away from the channel of the mounting seat 1, increasing the toilet space for the patient, thereby improving the comfort of the patient's toilet.

[0033] In order to improve the comfort of patients 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 comfort of patients when going to the toilet in winter, a constant temperature heating plate is embedded in the mounting seat 1.

[0034] like Figure 2As shown, the digging assembly includes a driving gear 14 meshing with the driven gear 5, and the driving gear 14 is coaxially provided with a motor 15 fixed in the installation box 4, and the driving gear 14 is rotatably connected to the installation box 4.

[0035] 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-to-back direction. 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.

[0036] After the patient has defecated, the specimen box cover equipped with the retention rod 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, and the two wedge-shaped blocks 12 can be driven to approach each other under the limiting action of the installation frame 9 to achieve clamping and fixing the specimen box cover, and the motor 15 can be started to drive the active gear 14 to rotate, thereby driving the driven gear 5 to rotate, thereby driving the installation frame 9 to rotate, and then driving the retention rod in the specimen box cover to rotate, so as to achieve non-contact sampling, and then the specimen box and the specimen box are threadedly connected, and 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 after sampling is in an inclined state, 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.

[0037] 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, 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, 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.

[0038] The stool of diarrhea patients is mostly watery, and it is impossible to take samples by using the retention rod. After the stool specimen cover equipped with the retention straw is fixed by the clamping assembly, the electric push rod 21 is controlled to stretch, and under the limiting effect of the fixed rod, the top of the two connecting rods 20 is moved away from the fixed rod, driving the middle of the connecting rod 20 to rotate around the pins installed on both sides of the fixed frame 18, and then the bottom of the two connecting rods 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 retention straw, and making its inner cavity a negative pressure state; when the bottom of the retention straw is in contact with the patient's watery stool by the adjustment assembly, the electric push rod 21 is controlled to shrink, 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 retention. In order to prevent the stool sample in the retention straw from falling due to the influence of gravity in the vertical state, causing the patient to dirty his hands when twisting the cover, the digging assembly can be used to tilt the retention straw to avoid the occurrence of the above situation.

[0039] In addition, the height between the fixed frame 18 and the mounting frame 9 can be set to be adjustable, which can be suitable for specimen boxes of different specifications equipped with retention straws.

[0040] like Figure 6 As shown, the cavity of the mounting seat 1 is rotatably connected with an adjustment rod 38 and a guide rod 39 respectively passing through the two ends of the feces collecting box 2, the adjustment rod 38 is threadedly connected to the feces collecting box 2, and the guide rod 39 is slidably connected to the feces collecting box 2. The feces collecting box 2 is driven to move forward and backward by rotating the adjustment rod 38, so as to adjust the position of the feces collecting box 2. A moving plate 41 is slidably connected in the feces collecting box 2, and two groups of mutually hinged connecting plates 40 are hingedly connected between the moving plate 41 and the feces collecting box 2 through the connecting rod. The free ends of the two groups of connecting plates 40 are respectively slidably connected to the feces collecting box 2 and the moving plate 41 through the connecting rod. The inner bottom wall of the feces collecting box 2 is provided with a second motor 42, and the output end of the second motor 42 is provided with a second threaded rod 43 rotatably connected to the feces collecting box 2, and the second threaded rod 43 is threadedly connected with a slider 44 slidably connected to the feces collecting box 2, and the free ends of the two groups of connecting plates 40 near the feces collecting box 2 are hinged to the slider 44 through the connecting rod, and the top of the feces collecting box 2 is provided with two hanging ears 45 through a spring.

[0041] The patient puts 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 seat 1. The patient's buttocks can press down the hanging ears 45 to make the feces collection bag firmly fixed on the hanging ears 45. After the patient goes to the toilet, the feces collection bag can be prevented from being separated from the hanging ears 45 due to the gravity of the feces, resulting in the feces not being completely dropped into the feces collection bag, and the feces specimen can be ensured not to be contaminated. When it is necessary to retain a sample after defecation, since the depth of the feces collection box 2 is obviously longer than the length of the retention rod / retention straw, it is inconvenient for the patient to take a sample. The motor 42 can be started to drive the threaded rod 43 to rotate, and then drive the slider 44 to move in the left and right directions, and drive the movable plate 41 to move up and down under the limit of the connecting plate 40. The upward movable plate 41 can drive the feces in the feces collection bag to move up, so as to facilitate sampling. After sampling, the disposable feces collection bag can be directly thrown into the trash can, which is clean and hygienic.

[0042] like Figure 1 As shown, two symmetrically distributed moving blocks 46 are slidably connected in the cavity of the mounting seat 1, a urine collecting cylinder 47 is connected between the two moving blocks 46 for damping rotation, an adjusting rod 38 and a guide rod 39 respectively penetrate the two moving blocks 46, the moving block 46 is threadedly connected to the guide rod 39, the moving block 46 is slidably connected to the adjusting rod 38, and 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.

[0043] When it is necessary to collect urine samples, 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 urine samples from patients.

[0044] Example 2

[0045] Compared with Example 1, Example 2 has the same structures as Example 1 except for the structure of the digging component.

[0046] 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.

[0047] The specific usage of the above embodiment is as follows: The device can be applied to toilets and squat toilets by fixing the assembly, which improves the applicability of the device. A disposable feces collection bag is placed in the feces collection box 2, and the feces collection bag is further fixed by the hanging ear 45. The position of the feces collection box 2 can be adjusted by the adjusting rod 38. When the patient sits on the mounting seat 1 to use the toilet, the feces completely fall into the feces collection bag, which can prevent the feces specimen from being contaminated by urine and water in the toilet. After defecation, fix the specimen box cover with the sampling tool (retention rod / retention straw) installed between the arc-shaped clamping blocks 13 in the clamping assembly, move the mounting plate, and fix the position of the mounting plate through the positioning assembly; start the motor 2 42, drive the threaded rod 2 43 to rotate, and then drive the slider 44 to move left and right, and drive the moving plate 41 to move up and down under the limit of the connecting plate 40.
