Description

Invention Title: Body Fluid Collection DeviceTechnical field

[0001] This creation is about a body fluid collection device, especially a collection device that collects lotion, urine or semen.Background technique

[0003] Although the prior art has several solutions for the collection of body fluids, such as lotion collection covers, urinary catheters of various calibers connected to urine bags, baby sticky urine collection bags, or condoms, these prior arts Body fluid collection devices still have many shortcomings. For example, breastfeeding mothers must constantly replace anti-galactorrhea pads, patients with urinary incontinence must constantly change heavy and stuffy diapers or indwelling invasive catheters to divert urine into the urine bag and collect The semen must be accurately injected into a small container for semen.

[0004] Since these prior art body fluid collection devices are designed to be able to be attached / removed repeatedly, however, this method sacrifices the strength of viscosity, and causes the body fluid collection devices to easily fall off due to insufficient viscosity after carrying the weight of body fluids. Making the body fluid collection device not easy to fall off is still an unsolved problem in the prior art.

[0005] In addition, a common problem in the prior art is that the position to be fitted is not always a continuous plane, such as female breasts or male and female external genitalia, which are all non-continuous planes, causing the fitting part of the body fluid collection device to fail to fit on the body surface during fitting. Distortion and deformation, and the user will also cause unstable fit when moving. Therefore, how to make the body fluid collection device easily fit on the curved body surface and adapt to dynamic changes is also a problem to be solved in the prior art.

[0006] In addition, another common problem in the prior art is that the body fluid penetrates into the bonding part of the body fluid collection device during use, resulting in a decrease in the bonding adhesion and causing the device to fall off. Therefore, how to improve the prior art so that the collected body fluid does not easily penetrate and fit. The location is also a problem to be solved.
