JPS5866053A - Measuring device for total urine volume - Google Patents

Abstract

PURPOSE:To provide a measuring device for total urine volume which prevents urine at the inside of a urine collecting tube from evaporating, is very handy to carry, and can sufficiently be operated even by a patient, by a method wherein a urine collecting tube, which is open at both ends, is combined with a packing plug mating the open end. CONSTITUTION:Urine is collected into a urine collecting cap 2, and the cap is placed in a position allowing the surface of a liquid to be levelled. A urine collecting tube 1 is vertically inserted in the urine collecting cap 2 with a plug 4 positioned down, and the tube 1 is pressed in the plug 4 as an operator ascertains that urine enters the inside of the tube 1 through an opening 9 and in a condition that the surface of a liquid in the cap is positioned in the approximately same level as that of the surface of a liquid in the tube. Then, the tube 1 passes through a small projection part 10 and is lowered, it is positioned between the nip formed by the inside of a hollow cylinder 5 and the outside of a plug body 8, it reaches the bottom of the cylinder 5 to close off the opening 9, and shuts off connection between urine in the tube 1 and urine in the cap 2. The urine collecting tube 1 is then removed, and the plug mates an upper opening end to prevent urine from evaporating. Then, from the volume of urine in the urine collecting tube 1, a total urine collecting volume can be estimated.

Description

[Detailed Description of the Invention] In tests for kidney function, diabetes, hypertension, etc., in addition to the patient's total daily urine volume, the amount of salt excreted in the urine, the amount of urinary sugar excreted, or the amount of urinary protein, It is required to measure the total excretion of substances such as creatine, potassium, and hormones. In such cases, an open container with a scale of 2 degrees is generally used, but it is not easy to accumulate and transport such urine over the next day, and this container cannot be stored in a warehouse. Not only does it require a large amount of space to store the urine, but if the container is not kept tightly sealed, urine evaporates very easily, producing a foul odor and interfering with the measurement of urine volume and substances present in the urine. It will be done.

The present inventors previously invented a measuring device to replace the total urine volume container in order to improve such drawbacks, and filed a patent application for
The application was filed as No. 68. The invention according to this prior application consists of a cylindrical container and a hollow tubular container located within the container whose cross-sectional area ratio with the cylindrical container is a constant ratio at any position in the vertical direction, A total pressure measuring device is provided in which a cylindrical container is provided with a discharge port that can be opened and closed for discharging into a storage tank or a chamber. In an actual preferred embodiment, the reservoir is provided at the bottom of the cylindrical container body. T 1” ” (I
41. :ii I:÷jJ) is planted at the bottom, and both containers are connected by a stopcock that can be opened and closed at 1μ, and the area ratio of both containers at the same location (height) is There is a discharge port at the bottom of the tubular container, which can also be opened and closed with a stopcock. During use, the urine excreted into the tubular container is maintained at the same level inside the tubular container, and then the urine inside the tubular container is maintained at the same level. After opening the stopcock and air vent valve, drop the urine into a storage tank, then discard the urine in the cylindrical container, repeat this operation, and calculate the total amount of urine and total amount of substances from the amount accumulated in this tank. This is what I am looking for. According to the invention of this prior application, since urine is not kept in a closed state during storage, there is no odor or discomfort, and there is an advantage that it does not require a relatively large amount of space.

However, in the case of the invention of the earlier application, the patient is required to operate at least two stopcocks and an air vent valve, so there are many cases where the patient makes a mistake in the operation. Since the container is planted in a container and a stopcock is provided in each container, the structure of the entire container becomes complicated and expensive.

The present invention solves the above-mentioned problems using the simplest and cheapest measuring device, and there is no bad odor caused by evaporation of urine (and it does not interfere with the measurement of urine volume and substances present in urine). (
In addition, the present invention provides a simple portable total amount measuring device that can prevent operational errors by patients and does not take up much space.

The total pressure measurement device according to the present invention is composed of a urine collection tube with both ends open for collecting urine, and a backing stopper to be attached to at least one open end of the urine collection tube, and the backing stopper is connected to a hollow cylindrical part. It consists of a stopper located inside the hollow cylindrical part and having a trapezoidal head section and a cylindrical part at the bottom, which is formed substantially integrally with the hollow cylindrical part, and the inner diameter of the hollow cylindrical part is the same as that of the urine collection tube. The outer diameter of the cylindrical portion of the stopper is approximately equal to the inner diameter of the urine collection tube, and the hollow cylindrical portion has a small number of openings (at least one opening) on the side surface of the tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The urinary collection tube and its backing plug according to the present invention will be described below with reference to illustrated embodiments. The urine collection tube 1 is a hollow tube made of a material such as acrylic resin or glass that prevents urine from evaporating inside, and both ends are open. A small portion of the tube end (colored #1' on both sides)
It is convenient if the tube is attached such that the position of the end of the tube can be observed from the outside when inserting the tube into the urine collection cup 2 and collecting urine. As an example, the inner diameter of the urine collection cup 2 is 60 mφ,
The height is 120-, the outer diameter of urine collection tube 1 is 8ranφ, and the inner diameter is 6.
Wtnφ.

If the total length is 160Ill++, the ratio of the inner diameter of cup 2 to the inner diameter of urine collection tube 1 is 60:6=10:1, and the volume of urine collected in cup 2 once is A.

It will be done. Here, when the urine collection tube 1 is vertically inserted into the cup 2, the amount of urine that enters the urine collection tube 1 becomes a volume a, which is 1/100 of A1, and is expressed as follows. Therefore, scale 3 for An in urine collection tube 1
If you shake it, you can save each urine collection tube after this urine collection.
If you do this, you can know the number of times a test subject uses it per day and the absolute amount. In other words, it is thought that 21 cups require about 10 urine collection tubes, and this number would be approximately the same as the number of times the subject collects urine in a day. The test subject only needs to carry approximately 10 urine collection tubes.

Next, the backing plug 4 used for the urinary tube will be explained. The backing plug 4 consists of a hollow cylindrical part 5 and a plug body 8 having a trapezoidal cross-section head 6 and a cylindrical part 7 located inside the cylinder 5 and preferably molded integrally therewith. The inner diameter of the hollow cylinder 5 is approximately equal to the outer diameter of the aforementioned urine collection tube 1, and the outer diameter of the cylindrical portion 7 is approximately equal to the inner diameter of the urine collection tube 1.
Moreover, at least one opening 9 for urine intake is provided on the side surface of the cylinder 5. This opening 9 is necessary to maintain the same level between the cup 2 and the tube 1 when taking urine from the urine collection cup 2 into the urine collection tube 1, thereby balancing the water heads of the urine collection cup 2 and the tube 1. I can do it. Also hollow cylinder 5
A small protrusion 10 is provided on the inner periphery of the tube, and the tip of the urine collection tube 1 is held by the small protrusion 10 so that it does not enter the lower part of the hollow cylinder 5 any further before urine collection.The position of the small protrusion 10 In this case, the tube 1 does not block the opening 10 and the end of the tube 1 is connected to the stopper 8.
It is located in a place like a door on the top of the mountain.

To use the heavy equipment, first, when collecting urine, collect urine into the urine collection cup 2 described above, and place the cup in a position where the liquid level is horizontal. The urine collection tube 1 is taken out, and one end of the tube is inserted, preferably a colored line 1' at the tip of the tube.
Check to see if it is in the correct position. Next, insert the urine collection tube 1 vertically into the urine collection cup 2 with the stopper 4 facing down, and make sure that the liquid levels in the cup and the tube are almost even. When the tube 1 is pushed into the stopper 4, the tube 1 descends past the small protrusion 10, is sandwiched between the inside of the hollow cylinder 5 and the outside of the stopper 8, reaches the bottom of the cylinder 5, and closes the opening 9. Communication between the urine in the tube 1 and the urine in the cup 2 is blocked. Thereafter, the urine collection tube 1 is taken out, a stopper of the same type or a different type is attached to the upper opening end of the tube 1 to prevent evaporation of urine, and one operation is completed, and the residual silver in the cup 2 is discarded.

In this way, if the urine excreted in one day is collected and stored in the urine collection tube 1 each time using the same procedure, the total urine volume for that day can be estimated from the total amount of collected urine. In this case, the problem is the error between this estimated urine volume and the actually measured urine volume, but this error
It corresponds to the height of , that is, h minutes. In the above example, the urine collection cup has an inner diameter of 60 mm and a height of 120 mm, and the urine collection tube 1 has an outer diameter of 8 mm and an inner diameter of 6 wan.

As a result of measurement using all f160m, there is an error of about 8qb at 50CC, and 4% for over 100CC.
Within this range, the average of 50 CC to 100 CC is 6 inches, and the total average is within 4 inches, which is a sufficient error range for practical use. Taking this into consideration, the urine collection tube 1 may be marked with a scale.

As described above, the urine collection device according to the present invention is easily portable, can be operated satisfactorily even by a patient, and evaporation of urine can be reliably prevented.
