Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for determining a state of urination,

The present invention relates to a system and method for determining the amount of urine, and more particularly, to a system and method for determining the amount of urine, and more particularly, to a system for setting personal information of a patient, The present invention relates to a system and a method for determining a state of urination of a patient by determining the presence or absence of urination in a patient by applying the set weight information to measured urine volume information.

The average daily urine volume of a person is about 1500 ml, and urine is 3 to 4 times for 24 hours. It can be used not only as an indicator of the filtration function of the kidney by the amount of urine in the lower part but also as an index for predicting the most important cardiac output to maintain balance of the human body and further the life.

The amount, color, and smell of urine that is produced by the blood of our body in the kidney is affected by water and food intake, general metabolism and intermediate metabolism.

For this reason, clinicians use urine excreted from patients as an important factor in checking the patient's condition.

Patients with normal renal function usually have a sufficient circulating blood volume if they excrete more than 1 ml per hour and body weight. However, if oliguria occurs, there is a shortage of circulating blood volume, an antidiuretic effect of anesthetic agents, stress due to surgery, impending acute renal failure, And the like.

In other words, if the change in urination can be known at any time, the physiological and pathological conditions of the patient can be grasped and coped with.

In general, the method of monitoring urination is to measure and record the amount of urine per hour.

The nurse usually reads the scale on the urine drain bottle every hour to measure and record the amount of urine.

Patient urination is a clinical indicator of kidney function, balance of fluid in the body, and related diseases, and it is very important to cause serious complications.

If the urine volume is not quantitatively measured, the medical staff can not quickly judge the urine condition, and medical accidents can occur. However, it is very inefficient for the nurse to check and record the urination of several patients every hour in a simple repetitive work.

Generally, abnormal urination is judged by polyuria when the urine output per hour is more than 100 ml, oliguria when it is 4 to 15 ml, and anuria when it is less than 4 ml.

Such conventional methods for determining the measurement of urine volume may cause an error depending on individual patient information such as body weight, presence of disease, information on fluid administration, and the like.

In order to solve such a problem, the present invention sets personal information of the patient including the physical condition of the patient and the type of disease, and information on the solution administration, and sets the predetermined weight information according to the patient's personal information and the set fluid administration information The present invention is directed to a system and method for determining the presence or absence of urination in a patient.

The charging unit 101 has a tapered shape that narrows from the upper portion to the lower portion, and urine is input.

The case 102 is formed with a certain space therein, urine is injected through a charging unit 101 formed on one side of the upper surface, collected in the accumulating plate 126, formed on one side of the upper side of the internal space, A rotation wheel 121 rotated by the urine load upon receiving urine falling down from above, and a detection unit 127 detecting a change in rotation speed of the rotation wheel 121 and converting it into an electrical signal. (120).

The detection unit 127 outputs a signal for calculating the yaw rate in proportion to the magnitude of the impact energy of urine to be injected.

The rotating wheel 121 has a structure in which a plurality of wing plates 123 are installed radially between a pair of side circular plates 122 and a structure in which the diameter of the side circular plate 122 is longer than the length of the wing plates 123. The wing plate 123 is composed of a straight central body 123b and an upper bent portion 123a and a lower bent portion 123c which are bent at an upper portion and a lower portion of the central body 123b at an angle.

The upper bending portion 123a and the lower bending portion 123c are slightly bent and rotated by the rotating wheel 121 to accurately contact the urine falling down from the collection plate 126 from the upper side.

The rotary wheel 121 is rotatably supported by a rotary shaft mounted at its center and is built in the case 102. [ The rotating shaft is a cantilevered structure that passes through one side of the case 102 and supports the rotating wheel 121 and rotates together with the rotating wheel 121. The supporting bracket 125 attached to the outside of the case 102, As shown in Fig.

The detection unit 127 includes a tachometer connected to the rotation axis of the rotation wheel 121 to convert the rotation operation of the rotation axis into a pulse signal or a rotary encoder connected to the rotation axis and digitizing the rotation operation of the rotation axis. In addition, the detecting unit 127 may be any means that can be connected to the rotating shaft to measure its rotational speed and to signal it.

The case 102 is formed at a position lower than the bottom surface 104 of the space in which the rotating wheel 121 is disposed, for measuring a urine volume of the urine that has fallen through the rotating wheel 121.

The case 102 is divided into a yaw rate measurement space for measuring the yaw rate and a yaw rate measurement space 103 for measuring the urination amount of the urine away from the lower side via the rotation wheel 121.

The urine measuring space 103 is formed in such a shape that the area of the urine measuring unit 120 is narrower than the space formed by the urine measuring unit 120 so that the urine away from the inner space of the case 102 through the rotating wheel 121 can flow in one direction, Thereby forming a discharge hole in the lower portion so as to be discharged to the outside.

The bottom surface 104 of the space in which the rotating wheel 121 is disposed is formed such that one side thereof is gently inclined so that the urine can be easily flowed into the measuring space 103, which is the other side from the one direction.

The urination amount measuring unit 130 includes a holding body 131 that is inserted into the case 102 through the outer circumferential surface of the case 102 at a position where the weft insertion space 103 is formed, And a flange 132 for providing a coupling site for fixing the outer circumferential surface of the base member 102 to be detached.

The entangled body 131 is provided with a cylindrical body 135 having a housing chamber 134 having only one end open at its inside and projections (projections) projected at a certain distance from the other end corresponding to one end of the cylindrical body 135 136, and the overall shape of the cross section is 'C'.

The flange 132 is formed on the outer peripheral surface of the one end of the cylindrical body 135 which is opened.

The body 133 is coupled to the case 102 by being screwed to the case 102 through the flange 132 in a state where the fitting body 131 is installed in the mounting hole 131 formed in the case 102 Shaped packing member 138 provided on the outer circumferential surface of the cylindrical body 135, as shown in Fig.

In this way, the entangled body 131 is provided with the urine volume sensing means 140 in the inside of the storage chamber 134 and the wiping wheel 141 coupled with the urine volume sensing means 140 is connected to a path It is provided on the

The urination volume sensing means 140 senses the number of revolutions of the wiping wheel 141 based on the flow of urination. Here, the wiping (or impeller) may be configured to rotate around the rotational axis by the amount of urination with the rotating shaft inside the weir measuring space 103.

The urine sensor 140 may be any one of an MR sensor, a Hall sensor, an inductor sensor, and an optical sensor. In the case of the inductor sensor, an inductive sensor ) Or a capacitive sensor may be used.

It is assumed that the urine sensor 140 of the present invention uses a hall sensor for convenience of explanation.

The wiping gear 141 is rotatably installed between the protrusions 136 and has a magnet 143 on each of the wings 142 and is rotated according to the urine falling vertically.

The urine sensing means 140 is installed in the chamber 134 of the cylindrical body 135 with one end of the cylindrical body 135 being hermetically closed and is rotated along the wings 142 of the wiper 141 And functions to intermittently react with the magnets 143 to generate and output an electric signal.

The urine sensor 140 is a Hall sensor which converts an intensity of the magnetic field into an intensity of an output voltage in response to the magnetic field of the magnets 123 to output an electric signal, Direction, direction of rotation, number of revolutions, and so on.

Since the Hall sensor is very small in size, the size of the cylindrical body 135 is relatively small.

The electrical signal output by the volume sensing means 140 is transmitted to the control device 200 to calculate the amount of urine discharged by the patient. The control device 200 is connected to the cigarette quantity sensing means 140 through a cable 144.

The control unit 250 of the control device 200 has a calculation function for calculating the amount of urination from the electrical signal output from the urine volume sensing unit 140 and displays the result through the display unit 260.

The size of the urine volume measuring unit 130 is considerably smaller and lighter by employing the magnet 143 and the urine volume sensing unit 140 to calculate the urination volume according to the rotation of the wiper 141. Thus, the size of the urination and blood-flow measuring device 110 can be reduced as a whole.

The urination measurement unit 130 collects urine and discharges the urine through the discharge hole without measuring the urination amount. The reason why the urine volume measuring unit 130 is configured is that the urine volume measuring apparatus 110 must be formed large when urine is collected and the urine volume is measured, which is disadvantageous in terms of hygiene such as smell.

The control device 200 includes a signal processing unit 230 for primarily processing electrical signals applied from the detection unit 127 of the yaw rate measuring unit 120 or the urine volume detecting unit of the urine volume measuring unit 130, An A / D converter 240 for converting an analog signal applied by the A / D converter 240 into a digital signal, and a controller 250 for processing the data acquired by the A / D converter 240 by a predetermined program .

The signal processing unit 230 includes an amplification unit 231 for amplifying an electric signal applied from the detection unit 127 of the urine measurement unit 120 or the urination detection unit of the urination measurement unit 130, And a filter unit 232 for filtering the noise of the amplified signal.

The electric signal applied from the detection unit 127 of the urine measurement unit 120 or the urination detection unit of the urination measurement unit 130 is amplified by the amplification unit 231 and amplified and the signal amplified by the amplification unit 231 is filtered by the filter unit 232 Converted into a digital signal by the A / D conversion unit 240, and then applied to the control unit 250.

The electric signal applied from the detection unit 127 of the urine measurement unit 120 senses the change in the rotation speed of the rotation wheel 121 in proportion to the magnitude of the urine impact energy falling from the insertion unit 101, .

The control unit 250 calculates the urine velocity falling from the input unit 101 using the electrical signal applied from the detection unit 127 of the yaw rate measuring unit 120 and displays the urine velocity on the display unit 260, .

The control unit 250 calculates the urine volume information based on the idle speed detected by the urine volume measuring unit 130. Here, the information on the amount of urination may be obtained in the form of information on the amount of urination per unit time or information on the number of times of urine volume per unit time. In addition, the control unit 250 may be mounted in the form of a microcomputer (MCU), and the urine volume information corresponding to the wiping frequency can be obtained by the central processing unit and the EEP-ROM.

The control unit 250 displays the cumulative information on the amount of urine accumulated in the current state in which the urine volume information is added, and stores the information in the data storage unit 270.

The control unit 250 applies a weight to cumulative information on the amount of urine accumulated in the current state according to the individual information of the patient inputted from the personal information input unit 210 and the information on the amount of the solution injected by the solution receiving unit 220, .

The control unit 250 generates information on the abnormal urination of the patient and transmits the information to the outside through the communication unit or outputs the information through the display unit 260.

FIG. 4 is a flowchart for explaining a method of determining an amount of urination according to an embodiment of the present invention, and FIG. 5 is a diagram illustrating a criterion for determining an amount of urination according to an embodiment of the present invention.

The personal information input unit 210 receives patient individual information such as the patient's weight and disease, and stores the information in the data storage unit 270 (S100).

The solution dispenser 220 sets the dispensation information including the dose of the solution, the kind of the solution, the rate of the solution dispensation and the time of the dispensation of the solution according to the patient's personal information including the patient's physical condition and the type of the disease, The liquid is administered according to the administration information (S102).

The urination measurement device 110 measures the urination amount of the urine input by the patient and stores the measured urination amount information in the data storage unit 270 (S104).

The control unit 250 of the control device 200 controls the control unit 250 so that the predetermined weighting value is set for the measured urine volume information of the current state according to the individual information of the patient inputted from the personal information input unit 210 and the infusion dose information set in the infusion dose processing unit 220 Information is applied to judge the presence or absence of urination in the patient (S106).

As shown in FIG. 5, when the urination amount per hour is 100 ml or more, it is polyunsaturated, 10 to 100 ml is normal, 5 to 10 ml is oliguria, and 5 ml or less is judged to be anorexia.

Among patients of the same weight, the dose of the fluid may be different when the patient is not a cancer patient or a cancer patient.

For example, a first patient who has undergone 80Kg of cancer surgery and a second patient who has undergone a minor trauma surgery rather than 80Kg of cancer surgery may be given more fluid than the first patient in the amount of fluid administered by the second patient have.

The urine volume of the first patient and the urine volume of the second patient may be different. If the urination volume of the first patient and the second patient is equal to 4 ml, neither the first patient nor the second patient can be judged as anuria.

That is, the first patient sets the weight to 3 ml according to the patient's personal information and the fluid administration information, and the second patient sets the weight to 1 ml according to the patient's personal information and the fluid administration information.

As shown in FIG. 5, since the urine volume of the first patient is 4 ml, the controller 250 reflects the weight of 3 ml in the anuric state and the final urination volume information (4 ml + 3 ml) corresponds to the urine volume> a + Therefore, the patient's urination is judged as oliguria.

5, the controller 250 reflects 1 ml of weight in the anuric state, and the final urination volume information (4 ml + 1 ml) is 5 ml and the urine volume> a +, and thus the patient's urination is judged as a mild urine.

In this manner, the control unit 250 applies the predetermined weighting information to the urination amount of the patient measured according to the patient's personal information and the liquid administration information, increases / decreases the measured urine volume information of the patient, And the presence or absence of urination is judged with respect to the measured urine volume information.

The weight information is preset in accordance with the patient's personal information and the information on the fluid administration.

The embodiments of the present invention described above are not implemented only by the apparatus and / or method, but may be implemented through a program for realizing functions corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded And such an embodiment can be easily implemented by those skilled in the art from the description of the embodiments described above.
