Problems solved by technology

[0005] This method is relatively simple, but requires 4 different test strips to determine the blank, and a positive control to check whether the peroxide has expired
Moreover, more critically, the operation steps are many, cumbersome and not suitable for long-term continuous detection

no. 1 example

[0044] The first embodiment: as figure 1 as shown,

[0045] The chromogenic agent storage part includes two independent spaces, a substrate storage part 11 and a chromogenic substance storage part 12. The substrate storage part 11 stores the substrate part, such as hydrogen peroxide, and the chromogenic substance storage part 12 stores the chromogenic part. Such as tetramethylbenzidine, when the delivery switch 6 is turned on, the pump of the pumping device 4 starts to work, and the substrate is partially injected into the toilet water seal, and stops when a certain amount is reached. The pump starts to work and stops when a certain amount is reached. After the excrement falls into the water, if it contains blood components, it will release hemoglobin, which will oxidize the substrate and release nascent oxygen, and then oxidize the color part to produce a characteristic blue color.

[0046] The second embodiment: as figure 2 as shown,

[0047] On the basis of the first embodiment, the developer storage part adds a third independent space, the surfactant storage part 13, for storing surfactants. When the delivery switch 6 is turned on, the surfactant storage part 13 corresponds to The pump first starts, and after pumping a certain amount, the pump corresponding to the substrate storage part 11 and the pump corresponding to the chromogenic substance storage part 12 start to work in sequence until the concentration that can be used for detection is reached.

no. 3 example

[0048] The third embodiment: as image 3 and Figure 4 as shown,

[0049] When the feces cause the water seal to be turbid, the reaction between the chromogenic agent and excess impurities in the feces will be caused. As in the first and second embodiments, the color development by using the chromogenic agent alone will become inconspicuous. In this embodiment, a foam generator 5 is added, and a part of the developer first enters the front end of the foam generating system, and is dispersed into the foam together with the surfactant and delivered to the water sealing surface of the toilet in the form of foam.

[0050] Since the foam is an aggregate of a large number of fine air bubbles composed of air, surfactant and water, the toilet has the function of preventing splash water and blocking the spread of bacteria when in use. Foam also has other properties that allow the developer to work more fully and effectively:

[0051] The anti-splash function of the foam reduces the po...

Abstract

The invention discloses a method for detecting biochemical indexes of excrement in a toilet and detection equipment using the method. The biochemical indexes of the excrement can be directly detected in a closestool, the detection result can be directly seen after defecating or flushing, and the use is convenient. The equipment is high in degree of automation, and continuous conventional detection is conveniently performed; foam serves as a color developing agent carrier, the observation is easy, and the interference of turbid sewage on the observation result is eliminated. The foam dispersion effect is good, the color developing agent and the substrate can be uniformly dispersed in a water seal, the dosage is saved, and convenient observation is realized; and moreover, according to a surfactant in the foam, the detection sensitivity is improved.

Description

technical field [0001] The invention relates to the technical field of toilets, in particular to a method for detecting biochemical indicators of excrement in a toilet and detection equipment using the method. Background technique [0002] Excreta contains a variety of biochemical indicators that are difficult to detect with the naked eye, including occult blood, urine sugar, nitrite, pH value, etc. This information is of great value for early detection of diseases. Take occult blood as an example. Occult blood refers to bleeding in the gastrointestinal tract that is so small that the naked eye does not see blood, and a small amount of red blood cells are digested and broken down so that they cannot be found under a microscope. Occult blood examination is of great value in diagnosing a variety of gastrointestinal bleeding diseases, and it is also an effective means of general screening for gastrointestinal tumors. Clinical studies have confirmed that microbleeding with canc...
