Description

Urine drainage system

The present invention relates to a urine discharge system by measuring the amount of urine in the bladder.

In the case of patients who do not feel the desire to urinate due to spinal cord injury or spinal surgery, etc., it is difficult to judge the timing of urination and catheterization on their own, so it is necessary to monitor the amount of urine in the bladder and urinate at the appropriate time. It is very important to carry out. If you fail to urinate and catheterize an appropriate amount at the appropriate frequency and time, it can cause anything from mild bladder dysfunction such as frequent urination, urinary incontinence, and urinary retention to complications such as urinary tract infection, hydronephrosis, and vesicoureteral reflux.

Previously, after a patient visited the hospital, it was possible to measure the patient's bladder volume and urine output using ultrasound equipment, but it was difficult to select the exact location of the ultrasound probe and it was expensive, so self-monitoring was required. It was not suitable for use for this purpose.

In addition, there is a conventional method of detecting bladder-related functions based on bioimpedance information, but this was a method using an implantable medical device that required a separate procedure, and was performed using electrical impedance tomography (EIT). Because it required expensive equipment to analyze impedance distribution images, it was difficult to use it for self-monitoring purposes.

Therefore, a system that can be used for self-monitoring and discharges urine at an appropriate time is required.

At this time, the light irradiation unit 110 may irradiate near-infrared rays having a preset irradiation signal intensity for each wavelength under the control of the control unit 160.

For example, the light irradiation unit 110 may be configured to include one light source 111, as shown in FIG. 2, and the light source 111 may be a laser diode (LD) or a light-emitting diode (LED). Alternatively, it may be composed of OLED (Organic Light-Emitting Diode).

The light detection unit 120 measures the signal intensity for each wavelength of the optical signal reflected and diffused from the bladder by multi-wavelength near-infrared rays irradiated to the bladder by the light irradiation unit 110.

For example, the light detection unit 120 may be configured to include a plurality of light sensors 121 arranged sequentially away from the light source 111, as shown in FIG. 2, and the light sensor 121 is It can be composed of PD (Photodiode), IR enhanced PD, APD (Avalanche Photodiode), CCD, or CMOS.

For example, the output unit 130 may include a status display lamp and/or a buzzer to display operating states such as starting operation, during measurement, and completion of measurement of the bladder urine volume measurement device 100 according to an embodiment of the present invention. You can.

In addition, the output unit 130 may further include a display module (not shown) that displays and outputs information received or processed by the bladder urine output measuring device 100 according to an embodiment of the present invention. That is, the display module can output analysis results (such as urine volume in the bladder) of the control unit 160, which will be described later, for the diffuse optics detected by the light detection unit 120.

For example, the display module may be implemented as a liquid crystal display, etc. Additionally, when the display module and a sensor that detects a touch operation form a mutual layer structure (i.e., a touch screen), the display module can be used as an input device in addition to an output device.

Additionally, the control unit 160 measures the amount of urine in the bladder by measuring the moisture content in the bladder through analysis of diffuse optics detected using the signal intensity for each wavelength of the measured optical signal.

That is, the control unit 160 calculates the reflectance using the reflected signal strength for each measured wavelength of the reflected and diffused optical signal, calculates the light absorption for each wavelength using the calculated reflectivity, and calculates the light absorption for each wavelength at the calculated wavelength. The water content in the bladder can be calculated using the light absorption of each star.

Referring to Figures 3 and 4, in the near-infrared band, the light of more than 85% of biological tissue components such as collagen, body water, lipid, deoxidized hemoglobin (HHb), and oxidized hemoglobin (O2Hb) An absorption peak exists. Therefore, it is possible to measure the amount of urine filled in the bladder by measuring the water content in the bladder. The wavelengths at which the light absorption peak of body water exists are 960nm, 1180nm, and 1440nm.

For example, the light absorption peak of water exists at wavelengths such as 960nm, 1180nm, and 1440nm among the near-infrared wavelengths, so as shown in Figure 4, near-infrared rays with a wavelength in the 650nm to 900nm band, which are insensitive to the light absorption peak wavelength of water, are used. The light irradiation unit 110 may be controlled to irradiate.

In order to measure the water content in the bladder, the control unit 160 first calculates the ratio of the reflected signal intensity of the light signal reflected and diffused from the bladder area to the irradiation signal intensity of the near-infrared rays irradiated by the light irradiation unit 110, Reflectivity can be calculated.

And, the control unit 160 can calculate light absorption for each wavelength using the following equation.

[Equation 1]

Here, R(ρ) is the reflectivity, ρ=(x, y), and a' is the albedo representing the reflectance at the surface, and a' = μ' _s / (μ _a + μ' _s ). , μ _a is the light absorption, μ' _s is the light output, z ₀ is the distance from the region of interest (ROI) to the measurement surface (skin surface of the bladder area), z ₀ = (μ _a + μ' _s ) ^-1 , μ _eff is the effective attenuation coefficient, μ _eff = [3 μ _a (μ _a + μ' _s )] ^1/2 , and r ₁ is the positive attenuation coefficient from the region of interest. As the distance to the positive impulse source, r ₁ = [(z - z ₀ ) ² + ρ ² ] ^1/2 , and z _b is the core of the extrapolate boundary condition, which assumes that the flux of photons disappears. It is the value of the virtual boundary, and r ₂ is the distance from the region of interest to the negative impulse source, which is r ₂ = [(z + z ₀ + 2z _b ) ² + ρ ² ] ^1/2 .

[Equation 2]

Here, R (ρ) is the reflectance, R _exp (ρ) is the experimental value of reflectance (experimental R) measured in physiological tissue using an experimental system, and α is a system parameter set in the experimental system.

In Equation 1 and Equation 2, light absorption μ _a , light output μ′ _s and system parameter α are unknown. Since at least three equations are required to calculate the solution of these three unknowns, one light source 111 and at least three optical sensors 121 are required, as shown in FIG. 5, respectively. In other words, using the reflected signal intensity measured at three points, three equations for the three unknowns of light absorption μ _a , light output μ' _s, and system parameter α can be generated from Equations 1 and 2. And from the three generated equations, the values of light absorption μ _a , light output μ′ _s , and system parameter α can be calculated.

And, the control unit 160 can calculate the moisture content of the first measurement area 10 from the calculated light absorbance using the following equation.

[Equation 3]

here, , , and are the extinction rates for each wavelength of oxidized hemoglobin (O2Hb), deoxygenated hemoglobin (HHb), body water (water), and lipid (lipid), respectively, [O2Hb], [HHb], [water], and [lipid ] are the contents of oxidized hemoglobin (O2Hb), deoxygenated hemoglobin (HHb), body water, and lipid, respectively, is the light absorption by wavelength.

In Equation 3, the contents of oxidized hemoglobin (O2Hb), deoxygenated hemoglobin (HHb), body water (water), and fat (lipid) can be calculated using the least squares method, and oxidized hemoglobin (O2Hb) and deoxygenated hemoglobin ( The content of HHb) can be calculated as an absolute value in mol units, and the contents of body water (water) and fat (lipid) can be calculated as relative values in % units.

According to an embodiment of the present invention, the light irradiation unit 110 and the light detection unit 120 may each include one light source 111 and at least five optical sensors 121.

That is, referring to FIG. 6, since the bladder 30 is located in the visceral layer 12 below the skin layer 11, the bladder 30 must be sufficiently far away from the light source 111 to obtain reflected and diffused optical signals. Additional optical sensors 121 such as R ₄ and R ₅ are required. Therefore, as described above, at least three optical sensors 121 are required to calculate the water content in the bladder, so as shown in FIG. 6, there are five optical detectors 120 (R ₁ , R ₂ , R ₃ , R ₄ and R ₅ ) may be composed of optical sensors 121.

Therefore, the control unit 160 calculates the first moisture content of the first measurement area 10 calculated using the optical sensor 121 of R ₁ , R ₂ and R ₃ , and R ₃ , R ₄ and R ₅ The second moisture content of the second measurement area 20 calculated using the optical sensor 121 can be calculated, and the moisture content in the bladder 30 can be calculated by subtracting the first moisture content from the second moisture content. .

Additionally, a power interface connected to a battery module for power supply may be implemented on the control board 170.

Here, the measurement board 160 and the control board 170 are provided with connectors 161 and 171, respectively, and can be electrically connected through the provided connectors 161 and 171.

The measurement substrate 160 directly contacts the patient's skin in order to irradiate light to the bladder area and detect the reflected light, so it may be formed of a flexible material.

By attaching it using an attachment means, the amount of urine in the bladder 35 can be measured as described above.

The remote controller 320 has a button for the user to input a drive command, and when the drive command is input through the button, it wirelessly transmits a drive command signal to the magnetic field valve pump 310.

For example, the remote controller 320 generates a magnetic field when a button is pressed, and the generated magnetic field is applied to the magnetic field valve pump 310, so that the magnetic field valve pump 310 can be activated and driven.

For example, the remote controller 320 is equipped with a communication function and can receive a drive command from the urine output meter 100 or the user terminal 200, and can receive a drive command from the urine output meter 100 or the user terminal 200.
