Description

Pollution-proof urine cup without dirting hand

Technical Field

The utility model relates to the field of medical equipment, specifically a dirty anti-pollution urine cup of hand.

Background

Urine is commonly called "urine" or "urine". Is a waste metabolite and toxin discharged from the organism, is a liquid, and is generally yellow or colorless. When human urine is formed, uric acid, urea, water, inorganic salts, glucose and other substances in blood flow through glomeruli, and are filtered into renal capsules through the filtration effect of the glomeruli to form raw urine. The wound is scratched in the field and has a plurality of germs, if no disinfectant is used, the wound can be cleaned by using mid-section urine and can be in time visited in a hospital, but the urine which is just discharged is not required to be used for cleaning the wound, and the urine is not required to be stored for later use. (midstream urine is normally considered sterile. in an emergency where no cleansing material is available, midstream urine can be used to flush wounds for cleansing purposes, but must be timely admitted to a hospital for a visit) the volatile acids in normal urine with ammonia odor often indicate chronic cystitis and chronic urinary retention after placement due to decomposition of urea by bacteria or the appearance of ammonia odor if urine is newly excreted. 90% of malodors may be a sign of bacterial infection. Possibly the E-COLI bacteria, which can cause the urine to generate odor. Attention should be drawn immediately and the doctor should be looked at as soon as possible. An optimistic estimate of burning sulfurous odors may be because you eat too much asparagus. Sulfur-bearing amino acids in asparagus can impart a taste to your urine. This taste will also gradually disappear with complete digestion of asparagus. If the sulfur smell lasts for more than two days, a urine examination needs to be performed in a hospital. Sweet fruit taste given that your urine gives off a sweet fruit smell, which can not be said to be due to you eating too much fruit salad. The odor of urine is likely due to infection by a bacterium. This taste is released by an acidic substance called ketone in the blood when the body tries to remove glucose.

However, the traditional urine cup has a simple structure, so that a patient can easily make liquid on the urine cup stick to hands when using the urine cup, and the urine contains more bacteria, which easily causes secondary infection of the patient.
