Embodiment 1

[0046] Embodiment 1: preparation composite dyeing agent

[0047] Mix the acetic acid solution with a mass concentration of 3%, the toluidine blue solution with a mass concentration of 1%, and the physiological saline with a sodium chloride mass concentration of 0.9% in a volume ratio of 5:2:3 to prepare a composite dye. In the composite dyeing agent obtained, the concentration of acetic acid is 1.5%, and the concentration of toluidine blue is 0.2%.

Embodiment 2

[0048] Embodiment 2: preparation composite dyeing agent

[0049] Mix the acetic acid solution with a mass concentration of 4%, the toluidine blue solution with a mass concentration of 2%, and the physiological saline with a sodium chloride mass concentration of 0.9% in a volume ratio of 5:2:3 to prepare a composite stain. In the composite dyeing agent obtained, the concentration of acetic acid is 2%, and the concentration of toluidine blue is 0.4%.

Embodiment 3

[0050] Embodiment 3: preparation composite dyeing agent

[0051] Mix the acetic acid solution with a mass concentration of 3.5%, the toluidine blue solution with a mass concentration of 1.5%, and the physiological saline with a sodium chloride mass concentration of 0.9% in a volume ratio of 5:2:3 to prepare a composite dye. In the composite dyeing agent obtained, the concentration of acetic acid is 1.75%, and the concentration of toluidine blue is 0.3%.

Abstract

The invention discloses a composite dyeing agent and an application thereof. The composite dyeing agent is mixed liquid consisting of an acetic acid solution, a toluidine blue solution and normal saline, wherein in the mixed liquid, the mass concentration of acetic acid is 1.5%-2%, and the mass concentration of toluidine blue is 0.2%-0.4%. The composite dyeing agent cooperates with a gastroenterological endoscope, so that the focus of a disease, which is difficult to distinguish can be convenient to find, and the composite dyeing agent is particularly used for esophagitis of dogs, and can improve the diagnosis rate and the sensibility of the esophagitis of the dogs.

Description

technical field [0001] The invention relates to the technical field of biochemistry, in particular to a composite dye and its application. Background technique [0002] With the rapid development of the pet medical industry, the requirements for pet disease diagnostic equipment are getting higher and higher. The diagnosis of pet dog esophageal disease has become a major problem in the pet diagnosis and treatment industry. Many dogs with esophageal injury do not show obvious clinical symptoms, it is difficult to find esophageal diseases by X-ray examination, and it is impossible to make an accurate disease diagnosis, and when they are fed with barium meal or iodine preparation contrast agent, there is choking into the trachea Choking hazard. [0003] Canine esophagitis generally refers to the inflammation of the esophagus caused by edema and congestion of the esophageal mucosa due to irritation or damage to the superficial or deep layers of the esophageal mucosa. Chemical ...
