Description
BACKGROUND Technical Field The present invention relates to a body fluid collection device, and more particularly to a collection device for collecting milk, urine or semen. Related Art It is difficult to collect timely body fluids which cannot be controlled, such as breast milk of nursing mothers, urine of infants and young children for testing, urine of urinary incontinence patients, and semen collected for reproductive testing. Such collection procedures often result in pollution to clothes and bedding as well as embarrassment of clients and collectors. Although there have been several solutions for the collection of such body fluids in the prior art, such as milk collection covers, urine bags connected with catheters of various diameters, stickup urine collection bags for babies, or condoms, these prior art fluid collection devices still have many shortcomings. For example, nursing mothers have to constantly change the anti-galactorrhea pad, urinary incontinence patients have to constantly change thick diapers or carry an indwelling urinary catheter to guide urine to a urine bag, and semen to be collected needs to be accurately injected into a small container. Because these prior art body fluid collection devices are designed to be able to be repeatedly adhered/removed, the adhesive strength may decrease after being used. As a result, after receiving an amount of body fluid, the body fluid collection device may fall off due to insufficient adhesive strength. This is a problem to be solved in the prior art. In addition, another problem commonly seen in the prior art is that the position to be adhered is not always a continuous flat surface, for example, female breasts or male and female external genitals are not continuous flat surfaces, and during adhesion, the adhesive part of the body fluid collection device does not fit the body surface and may deform, and movement of the user may also affect the firmness of adhesion. Therefore, how to make the body fluid collection device easily fit the curved body surface and adapt to movement of the user is also a problem to be solved in the prior art. In addition, another problem commonly seen in the prior art is that in use, the body fluid infiltrates into the adhesive part of the body fluid collection device, leading to a decreased adhesive strength and falling of the device. Therefore, how to improve the prior art so that the collected body fluid does not easily infiltrate into the adhesive site is also a problem to be solved. US 5,706,673 discloses a toilet flushable ostomy pouch comprises predetermined height and width convergent sidewalls and adhesive attachment to stoma with flexible plastics sheet. SUMMARY In view of the above problems, the present invention provides a body fluid collection device, which is easy to adhere to the human body and does not easily peel off, and is capable of collecting various body fluids such as milk, urine or semen while preventing leakage which may lead to contamination. To achieve the above objectives, the present invention provides a body fluid collection device as set out in the claims.
