This invention relates to the field of gene polymorphism detection technology and discloses a venous thrombosis risk gene detection kit based on LAMP technology. The kit includes primers and probes for detecting polymorphic sites in venous thrombosis risk genes, detection reaction system components, reagent A and reagent B, positive control A, positive control B, and a negative control. Reagent A and reagent B respectively contain matched primers and probes and the detection reaction system components. Reagent A is a 4G, C, AAG, G, or T reaction tube, and reagent B is a corresponding 5G, T, del, A, or C reaction tube. This invention avoids interference between primers and probes by physically isolating reactions of different nucleic acid sequences in independent reagents A and B. Simultaneously, it utilizes polymerase and cresol red to convert changes in system components into color changes, achieving simultaneous visualization and accurate genotyping of multi-target amplification signals without instrument assistance.

The invention discloses a deodorization paper diaper with a warning function, and belongs to the technical field of adult paper diapers. The technical problem that in the prior art, an adult paper diaper cannot have the dual functions of deodorization and warning at the same time is solved. The invention discloses a deodorization paper diaper with a warning function. The deodorization paper diaper with the warning function structurally comprises a surface layer, a flow guide layer, an absorption core layer and a bottom film in sequence from top to bottom, the surface layer fabric is obtained by adding a composite indicator into an EVA hot melt adhesive, then coating the EVA hot melt adhesive to the surface of a cotton fabric, and cooling and curing; the composite indicator is trivalent cobalt / chitosan ligand / glycine o-cresol red. The absorption core layer is obtained by paving a deodorant on fluff pulp, and the deodorant is spherical weakly alkaline resin grafted with a monomer. The deodorizing paper diaper prepared by the invention has the advantages of warning amide and absorbing sulfide.

Washing and disinfecting agent (100) for washing and disinfecting skin surfaces (1), comprising - a base agent (2) which is designed and intended to be used to wash and disinfect skin surfaces (1), characterized in that at least one substance additive (3) is mixed into the base agent (2), which after contact with the surface (1) assumes a different color consistency than the base agent (2) for a predeterminable period of time, so that the substance additive (3) serves as a marking agent by which the user can read whether the desired areas of the surface (1) to be washed and disinfected have been cleaned with a sufficient amount and a contact time of the base agent (2) has been completed, wherein the additive contains cresol red and the base agent contains at least one of the following substances: Cationic substances, amphoteric substances, and metals and metal salts, The change in colour takes a certain amount of time, and this time is called the exposure time, and both the colour and the exposure time can be shortened or extended depending on the concentration of the dye in the disinfectant, whereby the more of the dye is contained, the faster the discolouration takes place.
