Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a portable stool pH detection device and a detection method thereof. Background Art

[0002] Fecal pH reflects the acidity and alkalinity of the intestinal environment and is an important indicator for assessing intestinal health. By testing the pH value of stool, we can indirectly understand the digestive function and acid-base balance of the intestine. Under normal circumstances, the pH value of stool is 6.5-7.5. If the pH value of stool is greater than 7.5, it may indicate gastrointestinal bleeding. When gastrointestinal bleeding occurs, the blood and digestive fluid in the intestine may change the pH value of the stool. If the pH value of stool is less than 5.5, it may indicate intestinal flora imbalance. When the intestinal flora is imbalanced, harmful bacteria may multiply in large numbers, causing changes in the pH value of the stool. Through fecal pH testing, doctors can understand the patient's intestinal pH value and formulate targeted treatment plans.

[0003] At present, the pH test of feces is generally carried out by first sampling the patient's feces and then testing it with a pH meter. The current detection device is also not convenient for sampling the patient's feces. When sampling, since the patient takes the sample himself, the amount taken is difficult to control. At the same time, the sampling box cannot be removed and discarded in a non-contact manner, so there are still problems to a certain extent.

DETAILED DESCRIPTION

[0043] Example 1

[0044] A portable feces pH detection device, comprising: a detection body 1, a pH detection device 2, a push-out assembly, a receiving bucket 4, and a sampling assembly 5; the detection body 1 is a square hollow structure, the front end of the detection body 1 is detachably connected to the receiving bucket 4, and the rear end is detachably connected to the pH detection device, the inner rear end of the detection body 1 is fixedly connected to the sampling assembly 5, and the full-use assembly is mainly used to sample feces in the receiving bucket 4 without the need to directly hold the feces as a whole; slide grooves 11 are provided on both side walls of the detection body 1, and the push-out assembly is movably installed on the slide grooves 11; a limiting assembly 12 is movably installed on one side of the upper end of the detection body 1; specifically, the limiting assembly 12 includes a limiting spring 123 and a limiting rod 124, the middle of the limiting rod 124 A limit ring 121 is provided on the top, and the limit spring 123 is sleeved on the outer side of the limit rod 124. One end of the limit spring 123 is fixedly mounted on the upper end wall of the detection body 1, and the other end is fixedly mounted on the limit ring 121; the lower end of the limit rod 124 is fixedly mounted with a limit rod 122; the sampling assembly 5 includes: a damping rod 52 and a sampling rod 51, one end of the damping rod 52 is fixedly mounted on the side wall of the detection body 1, and the front end of the damping rod 52 is movably mounted with the sampling rod 51, and the end of the sampling rod 51 is fixedly mounted with a sampling groove, and a limit groove 511 is provided in the middle part of the lower end of the sampling rod 51; the limit rod 122 extends to the lower end of the limit groove 511 for limitation; the limit assembly 12 is released by pressing to control the sampling assembly 5 for sampling detection.

[0045] The specific process is: after pressing the limit rod 124 on the limit assembly 12, the limit spring 123 is stretched, and the limit rod 122 gradually moves away from the limit groove 511 until it is separated from the limit groove 511. At this time, under the action of the limit spring 123 inside the sampling assembly 5 (not shown in the figure, it is in the damping rod 52 and the sampling rod 51), the sampling rod 51 is retracted. At the same time, under the action of the damping rod 52, the sampling rod 51 will not move back and forth, and can be moved to the buffer box 16, so that the feces at the rear end of the sampling can enter smoothly for subsequent detection.

[0046] However, in the above process, it is necessary to continuously press the limit assembly 12 for limiting. After releasing it, under the action of the elastic force of the limit spring 123, the limit rod 122 will be retracted and rub against the sampling rod 51, so that the sampling rod 51 encounters resistance when it is retracted; there are still defects to a certain extent. In order to solve the above technical problems, in this embodiment, at the lower end of the detection body 1, a support rod 17 is fixedly installed on one side of the sampling assembly 5, and a wedge rod 171 is movably installed on the upper end of the side wall of the support rod 17, and the wedge rod 171 is connected to the support rod 17 through the limit spring 123; through such a setting, after the limit rod 122 moves, the wedge rod 171 can be pressed so that the wedge rod 171 compresses the limit spring 123 to move, and when the limit rod 122 moves to the lower end, it forms a limiting effect with the wedge rod 171, so that the limit assembly 12 will not be retracted, and the above technical problems can be completely solved at this time.

[0047] Example 2

[0048] In this embodiment, the buffer tank 16 described in Example 1 is provided; the buffer tank 16 is fixedly installed inside the detection body 1, the sampling rod 51 passes through the buffer tank 16 and extends to the outside of the detection body 1, and the pH probe 23 and temperature probe 24 provided on the pH detection device 2 are inserted into the buffer tank 16; the temperature can be detected by the provided temperature probe 24, and at the same time, the provided buffer tank 16 can enable the feces to dissolve in the buffer solution. On the one hand, the buffer solution is used for buffering, and on the other hand, the feces can be dissolved. The feces have different states. For a relatively hard state, the setting of the buffer solution can just dissolve it, which is convenient for the detection of the pH probe 23. At the same time, in this embodiment, a display screen 21 and a button 22 are provided on the pH detection device 2; the button 22 can be used to reset to zero, and the provided display screen 21 can be used for real-time display;

[0049] In addition, in the present embodiment, the sampling rod 51 and the sampling groove at the front end of the sampling rod 51 directly pass through the buffer solution box 16. If they simply pass through, there will be a hole in the buffer solution box 16, which will cause the internal buffer liquid to flow out. Therefore, in order to solve the above technical problems, in the present embodiment, a fixing frame 161 for the movement of the sampling rod 51 is opened in the middle of the buffer solution box, and a sealing piece 162 is installed on the fixing frame 161; the sealing treatment is performed by the provided sealing piece 162, and at the same time, a sealing plate is fixedly installed inside the position of the buffer solution box 16 corresponding to the sealing piece 162 for sealing. When the sampling rod 51 moves, it can be sealed by the provided sealing plate, that is, when it moves backward or forward, it can be sealed under the action of the sealing plate, and the rear end does not need a sealing plate. The contact positions of the sampling rod 51 and the buffer solution box 16 can be sealed by adding a sealing ring. In addition, in order to further enable the feces placed in the buffer solution box 16 to be fully mixed, in this embodiment, a magnetic stirrer 164 is installed inside the buffer solution box 16, and a magnetic generator 6 is separately provided at the lower end of the magnetic stirrer 164. The monitoring body 1 can be placed on the magnetic generator 6. At the same time, a display screen 21 and a button 61 are also provided on the magnetic generator 6. The display screen 21 can display the power, and the button 61 can control the start and stop of the magnetic generator 6. The stirring bar 164 is provided to stir the liquid inside, thereby stirring the feces so that it can be fully mixed with the buffer solution. However, since the feces state of human beings is uniform, Therefore, when stirring, if the sampling tank 53 is in a completely closed state, the flow of the internal liquid will hardly stir out the hard feces inside the sampling tank 53 during stirring. Therefore, in this embodiment, a leakage hole 531 is opened in the upper half of the sampling tank 53. When the feces is hard, it can be directly contacted and stirred through the leakage hole 531; when the feces is thin, it can be directly mixed with the buffer solution in the lower half of the sampling tank 53. Through the setting of the sampling tank 53 and the coordinated action of the stirring bar 164, both hard feces and thin feces can be fully mixed for detection after sampling.

[0050] Example 3

[0051] When the handle 31 is lifted up, the handle 32 is tightened and the handle 33 is tightened, so that the handle 33 is tightened and the handle 33 is loose, so that the handle 33 is loose.

[0052] Specifically, the receiving bucket 4 is installed on the detection body 1 by insertion, and a front baffle 42 is fixedly installed at the front end of the receiving bucket 4. The front end frame can better collect feces (widen the area), and the rear end is fixedly installed with a rear baffle 41 (the rear baffle 41 can effectively splash feces onto the detection body 1). The front baffle 42 is installed obliquely upward, and the rear baffle 41 is an arc-shaped structure and is bent and extended backward.

[0053] On the other hand, the present invention discloses a portable feces pH detection device and a detection method thereof, comprising the following steps:

[0054] S1: The feces are received by the receiving bucket 4, and then the limiting component 12 is pressed to release the sampling component 5 for sampling;

[0055] S2: Push the removal assembly to push out the receiving bucket 4 at the front end;

[0056] S3: pH buffer is initially placed in the buffer tank 16. The temperature is detected by the temperature probe 24 and fed back. At the same time, the pH is detected by the pH probe 23. The pH coefficient is corrected by the temperature feedback and displayed on the display screen 21.

[0057] S4: After the detection is completed, the pH detection device 2 is pulled out and reused after cleaning.

[0058] Furthermore, in S3, the pH coefficient correction process is to use the Nernst equation and the working principle of the pH meter to perform temperature compensation, specifically:

[0059] PHt=PH+α(xt)

[0060] Where: pHt represents the pH value after temperature compensation; pH represents the measured pH value;

[0061] α is the temperature coefficient; x is the standard temperature (degrees Celsius), and t is the actual temperature (degrees Celsius).

[0062] Specifically, when the temperature in the patient's body is 37 degrees Celsius, it is assumed that the measured pH is 6. However, since the temperature is lost during the discharge process, such as a loss of 1 degree Celsius, the standard value is 37 degrees Celsius, and the actual measurement is 36 degrees Celsius. The temperature influence coefficient of the pH electrode is 0.003pH / ℃, and the temperature after compensation is: PHt=6+0.003*1=6.003. The specific temperature parameters can be selected according to actual needs and will not be explained in detail here.

[0063] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the invention to only the specific implementation methods described.
