Body-Worn Urinal with Infrared Sterilization for Bedridden Patients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body-worn urinals for male patients are uncomfortable, difficult to maintain, and lack effective hygiene solutions, particularly for patients who are unable to urinate independently or are bedridden, leading to issues like urinary tract infections and diaper-related discomforts.
Innovation Solution
A body-worn urinal with a flexible fixing device for genitals, a far-infrared sterilizer for disinfection, and a diagnostic test kit integrated into the urine collection container, allowing for adjustable sizing, stable fixation, and hygienic urine management, including a urine discharge hose and container system that can be easily replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a body-worn urinal is worn for a long period of time, then urine collection is effective, but discomfort due to foreign body sensation and pain occur
Solution Approach 1:
The urinal device is divided into multiple components: an inner urinal portion that contacts the patient's body and an outer protective portion. This segmentation allows the inner portion to be soft and comfortable for prolonged wear while the outer portion provides structural support and can be removed for cleaning, thus reducing foreign body sensation and pain during extended use.
2Ease of operation
If diapers are used for urine disposal, then urine collection is simple, but rashes and discomfort occur when worn for long periods
Solution Approach 1:
The urinal device uses different materials with specific local qualities: the inner portion is made of soft, breathable, absorbent material that is gentle on the skin to prevent rashes, while the outer portion provides waterproof protection. This localized material selection addresses both ease of operation and skin comfort during prolonged wear.
3Productivity
If conventional body urinals are used, then urine collection is possible, but maintenance is difficult as components must be separated for washing
Solution Approach 1:
The inner urinal portion and outer protective portion are designed to be integrated in a way that maintains effective urine collection while allowing easy separation for cleaning. The components can be quickly detached and reattached, combining the productivity of efficient urine collection with the ease of maintenance through simple disassembly and assembly.
4Ease of manufacture
If a fixed-size urinal is used, then manufacturing is simple, but it cannot accommodate patients with different genital sizes
Solution Approach 1:
The urinal device incorporates flexible, expandable materials that can dynamically adjust to different sizes. The inner portion is made of elastic material that can stretch and conform to various genital sizes, while the outer portion can be adjusted or exchanged. This dynamic design maintains manufacturing simplicity while achieving versatility across different patient anatomies.

AI summary
The present invention relates to a body-worn urinal for male patients, which is easy to wear even when the patient is lying down or moving, and which is capable of ventilation even when being worn for a long time without causing discomfort due to a foreign body sensation or pain, and is capable of sterilization and treatment by means of a built-in infrared sterilizer, thereby enabling natural urination and hygienic maintenance. Disclosed is the body-worn urinal for male patients, comprising: a body connecting and fixing device formed of a holder for fixing male genitalia; a urine collection cup for collecting urine, the urine collection cup comprising a water collection part formed on the upper side thereof and having a spherical inner space, a lamp holder formed on the upper end of one side of the water collection part so as to penetrate therethrough, a connection part which is formed on the other side of the water collection part and is open such that the body connecting and fixing device is connected thereto, and a drainage part which is formed downward from the water collection part so as to discharge urine; a far-infrared sterilizer coupled to the lamp holder of the urine collection cup; a urine discharge hose for discharging the urine collected in the urine collection cup; and a urine container to which the urine discharge hose is connected so as to temporarily store the urine, wherein the body connecting and fixing device further comprises Velcro attachment bands which are connected and fixed to both side ends of the outside thereof so as to be attached and fixed to Velcro attachment portions of a patient diaper.
