Description

Urine Volume Measuring Apparatus {APPARATUS FOR MEASURING URINE VOLUME AND PATTERNS} The present invention relates to a urine volume measuring device used for medical purposes, and more specifically, to a portable urine volume measuring device capable of precisely measuring urine volume into objective numerical values. Generally, a urine bag is a urine bag used to assist urination in unconscious, severely ill hospitalized patients or patients with limited mobility who are unable to defecate on their own after surgery. Therefore, when a catheter is inserted into the bladder through the patient's urethra and a urine bag is connected to the lower end of the catheter, urine discharged from the bladder is sent through the catheter to the urine bag and stored. However, as shown in FIG. 1, the conventional urine bag (U) is installed to collect urine flowing in the direction of gravity through the catheter (B) after being fixed to the bottom of the patient's bed using a string (A), so it is not easily visible. Therefore, if care is not taken, an accident may occur in which urine fills the urine bag (U) and flows back into the urethra. In this case, the closed system that maintains the sterility of the urine bag (U) is broken, making it vulnerable to infection, so it must be replaced with a new urine bag (U). This increases the patient's medical costs and increases the workload of the nurse. Meanwhile, in patient treatment, urine volume and characteristics are key indicators for understanding the clinical course and adjusting the direction of treatment, so accurate measurement is required. Therefore, in practice, nurses must periodically check and record urine bags (U). However, conventional urine bags (U) are secured to the patient's bed using a strap (A), so they are prone to tilting, and since they are made of a flexible material, the degree of elasticity varies depending on the amount of urine, making it difficult to accurately check the amount of urine. Furthermore, since the urine volume is checked by reading and recording the scale marked on the urine bag (U), the precision is low. In addition, even when measuring urine characteristics, the accuracy is low because it is performed by a nurse making a subjective judgment based on visual observation of the urine collected in the urine bag (U). In addition, when analyzing various analytes in urine, there is the inconvenience of having to collect urine in a urine bag (U). In particular, the measurement of urine volume and characteristics as described above is carried out by nurses visiting patients' rooms at scheduled times several times a day to personally check urine bags (U). However, considering the nature of nurses' duties, who must simultaneously perform nursing and caregiving tasks, managing an accurate urine test schedule presents serious difficulties, and thus improvement is required.
