Abstract

The invention provides a hypoallergenic condom, which comprises a condom substrate and hypoallergenic active ingredients, wherein the hypoallergenic active ingredients are 0.7-7 percent based on the total weight of the condom, and consist of baicalin and a medlar extract in the weight ratio of (0.01-1):(3-5). According to the hypoallergenic condom, the hypoallergenic active ingredients are added into the condom substrate, so that skin discomfort and allergy symptoms caused by the use of the condom are avoided, undesirable consequences are avoided, and the application range of the product is enlarged.

Description

Irritability proof condom

Technical field

The present invention relates to a kind of condom, be specifically related to a kind of irritability proof condom.

Background technology

Condom is the most frequently used in current male contraception technology and one of the simplest instrument, and it has safety, reliable, usage is easy, economical, harmless, do not disturb the plurality of advantages such as any physiological function.In addition, condom is prescription of preventability transmitted diseases also, as syphilis, gonorrhea, acquired immune deficiency syndrome (AIDS) etc., prevents the stimulation of smegma to cervix uteri, reduces the danger that cervical cancer occurs.The physics delay condom of local thickening can reduce the sensitivity of glans penis, thereby extends sex time, and to premature ejaculation, patient has therapeutical effect.Use condom late trimester of pregnancy, premature labor or the neonatal death that can prevent intrauterine infection and cause thus.In a word, along with popularizing of knowledge on reproductive health, condom is as the instrument of the sexually transmitted disease (STD) of practising contraception, prevent and treat, raising life quality, by increasing people is taken like a shot.

At present condom is made by natural emulsion, and the chemical drugs added in preparation process due to the latex raw material and gather natural contamination in the latex process can cause that anaphylaxis appears in minority allergic constitution user.The male shows as penis head flushing, and ulceration, erosion etc. occur when serious for pruritus and twinge; The women shows as pudendum and vagina has pruritus and burn feeling, vaginal mucosa hyperemia, edema, leucorrhoea grow in quantity etc.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of irritability proof condom, adds hypo-allergenic active component in the substrate of condom, not there will be in use allergic symptom, greatly increases the security performance of condom.

Technical scheme provided by the invention is to provide a kind of irritability proof condom, comprises condom substrate and hypo-allergenic active component, it is characterized in that: with the total restatement of condom, the weight content of described hypo-allergenic active component is 0.7～7%; Described hypo-allergenic active component is comprised of Radix Scutellariae glycosides and wolfberry fruit extract, and its weight ratio is 0.01～1:3～5.

The preparation method of above-mentioned wolfberry fruit extract is: Fructus Lycii is added to water and mix, under 80～100 ℃, extract 1～2h, filter, get filtrate concentrating, drying, obtain.

As preferably, the weight content of described hypo-allergenic active component is 2～5%.

Above-mentioned substrate is latex.

The preparation method of irritability proof condom is as follows:

1) latex is centrifugal, batching, add hypo-allergenic active component, mixes, and sends into head tank.

2) mold cleaning, dry, and the impregnation slurry is dried 50min under 100～110 ℃, and the impregnation slurry, dry 50min for 60～100 ℃ again, and crimping is dried 50min under 100～130 ℃, the demoulding, and 50～60 ℃ of lower foam washing 30min, dry 1h for 120 ℃, and the packing that oils gets final product.

The present invention be take pure natural Radix Scutellariae glycosides and wolfberry fruit extract as hypo-allergenic active component, safe and effective, without any untoward reaction, can effectively avoid the appearance of allergic symptom, has greatly strengthened the security performance of this product, has enlarged the scope of application of product.

The specific embodiment

The present invention is further elaborated for following specific embodiment, but not as a limitation of the invention.

3, experimental result: in Table 3.

Table 1

Table 2

Mean scores	Intensity
		0	Without irritated
1～2	Slight irritated
		3～5	Moderate allergy
6～7	Hyperirritability
