It is a perspective view which shows the urine flow measurement toilet bowl using the urine collection container of this invention. It is a perspective view which shows the whole urine collection container in embodiment of this invention. FIG. 3 is an open view of the urine collection container of FIG. 2. It is sectional drawing of the western style toilet bowl which shows the use condition of the urine collection container of this invention.

Hereinafter, an example of an embodiment of the urine collection container of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a urine flow measuring toilet using the urine collection container of the present invention. In the urine flow measuring toilet A, the sanitary washing device 2 that supports the toilet seat 21 is rotatably supported on the upper part of the Western-style toilet 1, and the urine flow measuring function unit (not shown) is installed at the rear. It is stored in the cabinet 3. And the urine collection container 40 concerning this invention is used in the state floated on the stored water inside the Western-style toilet 1 as shown with the broken line.

  The Western-style toilet 1 is made of earthenware or resin, and has a toilet cleaning function unit (not shown) that allows a user to supply cleaning water toward the bowl unit 11 that excretes excrement such as large and small urine. The Western-style toilet 1 is formed with a trap channel 14 (see FIG. 4) including an ascending pipeline from the bowl portion 11 and a descending pipeline subsequent thereto, and a downstream side of the trap channel 14 is a drainage pipe for a building. Connected to a road (not shown). For this reason, a reservoir (see FIG. 4) is formed at the bottom of the bowl portion 11, and the user (hereinafter sometimes referred to as a subject) operates the toilet bowl cleaning function portion after excretion to operate the bowl portion 11. By supplying cleaning water toward the sewage, excreta can be discharged into the drainage pipe together with the stored water. Thus, the urine flow measuring toilet A is a flush toilet that can be used for normal excretion. In addition, a backrest 31 in consideration of supporting the upper body of the user is installed on the front surface of the cabinet 3.

  The operation / display unit 7 includes a sanitary washing device operation remote controller 71 and an excretion information measurement remote controller 72 and is attached to a wall. The measurement result may be transmitted not only from the printer 6 disposed above the cabinet 3 but also as electronic information via the hospital LAN.

  When the subject measures the urine flow rate, the urine flow measurement toilet A operates the excretion information measurement remote controller 72 to discharge a part of the accumulated water in the bowl portion 11 to the drainage pipe. Reduce. When the urine is urinated toward the bowl portion 11 in the same manner as a normal excretion action in the state where the water level of the accumulated water is lowered in this way, the amount of accumulated water stored in the bowl portion 11 is increased by the urine and the water level is increased. The amount of change is measured as a change in water pressure, and the amount of urine discharged and the urine flow rate are measured by converting the change into a change in the amount of accumulated water based on a relational expression stored in advance.

  Next, an example of the urine collection container according to the present invention will be described. FIG. 2 is a perspective view showing the entire urine collection container in the embodiment of the present invention, and FIG. 3 is an open view of the urine collection container in FIG.

  The urine collection container 40 is particularly recommended for a subject who urinates in the Western style toilet 1 in a sitting position, and as shown in FIG. 2, a hexagonal bottom wall 41 and an outer periphery of the bottom wall 41. It is comprised by the side wall part 42 standingly set up from the perimeter of this. The space between the upper surface of the bottom wall portion 41 and the upper end of the side wall portion 42 forms a urine collection space for storing urine released by the subject. Then, by floating and using the bottom wall 41 in contact with the upper surface of the stored water of the Western-style toilet 1 (hereinafter also referred to as the stored water surface), at least a part of the urine excreted by the subject is captured in the urine collection space. Can be collected and saved.

  In the urine collection container 40, a part of the side wall part 42, specifically, the side wall part 42 erected vertically from two adjacent sides of the hexagonal bottom wall part 41 is continuous with the upper end thereof. A guide portion 43 is formed. This guide part 43 is formed only in a part of the side wall part 42, and therefore does not surround the entire circumference, and therefore does not form a urine collection space.

  Since the guide unit 43 can receive urination from the subject and guide it to the urine collection space, the guide unit 43 can be used in a state where the guide unit 43 is positioned in the direction of urination in the subject, so that a necessary amount of urine sample can be reliably obtained. It is possible to collect in Specifically, the guide part 43 can easily catch the urination of a male subject who urinates in a standing position by floating on the water surface so that the guide part 43 is on the rear side (the cabinet side in FIG. 1). On the other hand, by using the guide unit 43 so as to float forward on the water storage surface, the urination of the subject who sits and urinates can be easily received by the guide unit 43.

  The height of the guide portion 43, that is, the height from the upper end of the side wall portion 42 to the upper end of the guide portion 43 is about twice as high as the height from the bottom wall portion 41 to the upper end of the side wall portion 42. It has become. For this reason, if the height of the side wall portion 42 for forming the urine collection space in the urine collection container 40 is increased, the overall height of the urine collection container 40 is increased, giving the subject a feeling of pressure. Although there is a fear, such a feeling of pressure will not be given by raising the guide part 43, and not only the urine of women generally discharged directly into the pooled water, but also the urination of men excreted from the penis It can be reliably received and can be collected in a container simply by performing normal urination.

  The urine collection container 40 is formed of water-soluble paper. Specifically, a piece of water-soluble paper is cut according to the development shown in FIG. 3, bent at a folded portion 42a between adjacent side wall portions 42, and bonded with a water-soluble adhesive. The folded portion 43a between the portions 43 is similarly folded and bonded, so that the urine collection container 40 having the structure shown in the perspective view of FIG. 2 is manufactured.

  As described above, the bottom wall portion 41 and the side wall portion 42 are manufactured from one continuous piece of paper that is not cut, so that the urine collection space formed by the bottom wall portion 41 and the side wall portion 42 is made watertight. Can be secured. Further, when the outer edge of the bottom wall 41 is a polygonal flat surface, it is manufactured that the side wall 42 rises vertically from the bottom wall 41. Compared to, it can be done easily.

In addition, since the urine collection container 40 is water-soluble paper, it can be washed together with the toilet water after use, and then transported to the drainage pipe. This can reduce processing load and hospital infection. Disposal processing is possible in a reduced state. The paper material is preferably paper having a certain degree of shape retention and a certain degree of water resistance, and paper having a water-repellent coating treatment that does not impede water solubility on one or both sides may be used. Specifically, paper that has been put into practical use as a “stool collection sheet” having a function of holding excrement for a predetermined time during a health check can be used. For example, provided by Daio Paper Co., Ltd. No. is listed in “Maruhishi Papertech Co., Ltd. Special Sample Book”. “Product name: water-soluble paper, basis weight 43 g / m ² ” listed as No. 87 is recommended. Further, since the urine collection container 40 is formed of paper, it can be folded into a flat plate shape during storage, and the storage space can be reduced.

Next, the usage state of the urine collection container 40 of this embodiment will be described with reference to FIG. FIG. 4 is a cross-sectional view of a Western-style toilet bowl showing the usage state of the urine collection container of the present invention, FIG. 4 (a) shows the state before urine collection, and FIG. 4 (b) shows the state after urine collection. 4 (a) and 4 (b), the water level of the stored water 12 in the bowl portion 11 before urine collection (before the subject urinates) is WL1, and the bowl after urine collection (after the subject urinates). The water level of the stored water 12 in the part 11 is indicated by WL2.
As shown in FIG. 4A, before the urine collection, the bottom wall portion 41 of the urine collection container 40 is set in a state where it is in contact with the water surface (WL1) of the stored water 12 of the Western-style toilet 1 and is in a floating state. In the state before the urine collection, the urine collection container 40 is in a state of floating in the stored water 12, and the water level of the stored water does not change depending on the presence or absence of the urine collection container 40.

  When the subject urinates in this state, at least a part of the excreted urine enters the urine collection space through the upper end opening of the side wall portion 42 of the urine collection container 40 and is stored in the urine collection container 40. Urine that has not entered the urine collection container 40 flows into the stored water 12. Since the buoyancy of the urine collection container 40 is extremely small, the urine collection container 40 sinks into the pooled water 12 due to the weight of the urine stored in the urine collection space, and as shown in FIG. And the water surface height (WL2) of the urine mix of the stored water 12 of the Western-style toilet 1 is substantially equal. Therefore, even if the urine collection container 40 is used, the total amount of urine that the subject urinates from the Western-style toilet 1 by measuring the level change of the stored water with the urine flow measuring device A using the Western-style toilet 1 The measurement value does not differ depending on whether or not the urine collection container 40 is used. As a result, there is no need for correction, and urine flow measurement and sample collection can be performed simultaneously.

  The subject's urine flow rate (amount of urination per unit time, mL / second) is about 100 mL / second at maximum, and the size of the urine collection container 40 is such that the length of the diagonal line of the bottom wall 41 is about 150 mm, If the depth of the side wall part 42 is set to about 35 mm, the diagonal length of the bottom wall part 41 becomes about four times the height of the side wall part 42 erected vertically from the bottom wall part 41. It is possible to prevent capsizing by momentum. Further, the urine collection container 40 may be large enough to float on the stored water 12 and collect a necessary urine sample. Therefore, the height of the side wall portion 42 can be reduced and the size can be reduced. The subject who sits down can perform normal urination without feeling a sense of pressure.

  Further, the urine collection container 40 has the side wall portion 42 rising substantially perpendicular to the bottom wall portion 41, so that when the urine is collected in the urine collection space and submerged in the stored water 12, the side wall portion 42 is It is difficult to receive resistance by the stored water 12, and the shape is stable, so that the stored water can be prevented from entering the urine in the urine collection space. The required amount of urine sample is about 25 mL even if the secondary examination is taken into account. Therefore, even if there are individual differences in the direction of urination or the female urination state is uncertain, If it is the same size as the area of the accumulated water, the necessary amount of urine can be collected without any problem.

  As described above, an example of the embodiment of the present invention will be described. However, the urine collection container according to the present invention is not limited to this, and the bottom wall portion 41 of the urine collection container 40 is a quadrilateral or circular shape other than a hexagon. It may be oval or oval, and various modifications within the range including the features of the present invention are possible.
