The urine collecting device 1, the holding table 2 and the hose 3 are all made of a synthetic resin, and are individually formed integrally except for a part of the urine collecting device 1.
[0016]
2 is an enlarged side view of the urine collector 1 shown in FIG. 1, FIG. 3 is an enlarged plan view of the same, and FIG. 4 is an enlarged sectional view taken along line IV-IV in FIG.
The urine collecting device 1 has a vertically long elliptical cylindrical funnel shape that is narrowed in the left-right direction in plan view, and has a urine collection port 11 formed at the upper end and a urination port 12 formed at the lower end, and includes the urine collection port 11. The upper approximately 1/3 portion has an elliptical cylindrical shape, and the cross-sectional area is the largest, and the lower approximately 2/3 has an elliptical cylindrical shape. As shown in FIG. 3, it is reduced in size and has a substantially inverted triangular shape. Further, a pipe-like urine outlet 12 projects outwardly at the lower end, and one end of the hose 3 is connected thereto. It is like that.
[0017]
On the outer peripheral surface of the urine collecting device 1, there are provided ridges 13 over the entire circumference of the outer periphery at a position approximately 1/3 from above in the upper and lower directions, and a plurality of peripheral edges support a plurality of ridges. Reinforcing ribs 14 are provided so as to project outward, and a handle 15 is provided that extends approximately 2/3 of the lower side in the upper and lower directions and extends upward and downward along the front side surface of the outer periphery. Yes.
The collar 13 has an elliptical shape that matches the cross-sectional shape of the funnel-shaped portion of the urine collector 1, and its size is slightly larger than the opening of the cylindrical body 22 as shown in FIG.
[0018]
Further, the urine collection port 11 of the urine collection device 1 surrounds the urethra mouth of the human body and can be brought into close contact with the peripheral portion from the front side in the front-rear direction to a position of about 2/3 from the collar 13 as shown in FIG. After the height h is gradually reduced and reaches the lowest height h ₀ , the height h is increased again toward the rear side. The shape of the urine collection port 11 in the urine collection device 1 is matched to the shape of the opening of a conventionally known stamen for women, and can be used for both girls and boys.
[0019]
Further, the peripheral edge of the urine collection port 11 of the urine collection device 1 has a wall thickness 11a which is slightly larger than the other portions to form a strip-shaped thick edge portion 11a, which is elliptical in accordance with the planar shape of the urine collection port 11. A flexible rubber elastic ring member 16 having an inverted U-shaped cross section is detachably fitted in the U-shaped groove 16a to the thick edge portion 11a of the opening. As a result, the skin can be prevented from being damaged even when the urine collection port 11 of the urine collector 1 is directly applied to the peripheral portion of the urethra of the human body, and the adhesion with the skin is improved to prevent the urine from leaking to the outside. It becomes possible.
[0020]
Further, the urine outlet 12 provided at the lower end of the urine collector 1 is opened at the tip of a pipe portion extending from the lower end of the urine collector 1, and the end of the hose 3 is fitted on the outer peripheral surface of the pipe portion. A return stop step 12a is formed for preventing the slipping off.
5 is an enlarged front view of the holding table 2 shown in FIG. 1, FIG. 6 is an enlarged plan view of the same, and FIG. 7 is an enlarged sectional view taken along line VII-VII of FIG.
The holding base 2 is open at the lower end, and the upper end is closed except for the pipe portion constituting the urine inlet 21 that opens at the center, and is elliptically long in the left and right directions, which is narrowed by pushing upward and downward. A holding leg 23 that is bifurcated in the middle is integrally provided on the outer peripheral surface near the upper end side of the cylindrical body 22 that forms the structure.
[0021]
The inflow port 21 is opened at the tip of a pipe portion projecting outward from the central portion of the upper end side surface of the closed cylindrical body 22, and the pipe portion is a pipe of the urination port 12 in the urine collector 1. It has the same shape as the part, and on its outer peripheral surface, there is formed a detent step 21a for preventing slipping when the end of the hose 3 is externally fitted.
In addition, a thread is formed on the inner peripheral surface of the cylindrical body 22 so as to communicate with the inlet 21 and screw the mouth of the urine storage container 5 concentrically with the inlet 21. A cylindrical mounting port 24 and an air vent hole 25 for discharging air from the inside of the urine storage container 5 mounted inside the mounting port 24 are provided.
[0022]
The outer end of the air vent hole 25 is opened on the outer peripheral surface of the upper end of the cylindrical body 22, and the inner end is opened when the mouth of the PET bottle as the urine storage container 5 is screwed into the mounting opening 24. The air in the plastic bottle flows out from the air vent hole 25 in response to the urine flowing into the plastic bottle during urine collection, so that the urine can smoothly flow into the plastic bottle. It is like that.
[0023]
In the embodiment, since the mounting port 24 of the mouth portion of the PET bottle in the holding base 2 and the air vent hole 25 are close to each other, when the urine flows into the PET bottle, the air vent hole 25 is exposed to the outside. Since there is a risk that urine will flow back to the outside due to the flowing out air, a shielding plate may be provided around the air vent hole 25 to block the urine from flowing in.
[0024]
One end of the holding leg 23 is integrally formed over one half of the outer circumferential surface near the upper end of the cylindrical body 22, and the other end is wider than the cylindrical body 22. 23a and 23a are formed.
As a result, the PET bottle with the mouth portion attached to the attachment port 24 and the feet 23a and 23a is supported by the three-point support so that the PET bottle is held on the floor in a state inclined at a predetermined angle of 30 to 60 ° with the mouth portion upward. I have to do it.
[0025]
A holder 26 with a stopper 26b for holding the cap 5a of the plastic bottle is provided on the outer peripheral surface of the cylindrical body 22 opposite to the side on which the holding leg 23 is fixed. As shown in FIGS. 1 and 5, the holder 26 is formed on the outer peripheral surface of the cylindrical body 22 with the locking pieces 26a, 26a having an inverted L-shaped cross section facing each other with a predetermined interval corresponding to the approximate diameter of the cap 5a.

As a result, after the urine storage container 5 is used, it is possible to prevent the inconvenience that the cap 5a that closes the mouth of the urine storage container is misplaced and cannot be covered.
[0026]
As shown in FIG. 5, the cylindrical body 22 is shifted by 90 ° in the long and short diameter directions of the urine collection port 11 of the urine collector 1 so that the major axis direction is left and right, and the minor axis direction is upward and downward. Further, the area of the opening is slightly larger than the area of the urine collection port 11 of the urine collection device 1 and slightly smaller than the major and minor diameters of the collar 13, as shown in FIGS. 9 and 10. When the urine collection port 11 is fitted into the opening of the cylindrical body 22 in a state where the urine collection port 11 is tilted 90 ° in the circumferential direction, the plurality of ribs 14 formed on the outer periphery of the urine collection port 11 are formed on the inner peripheral surface of the opening of the cylindrical body 22. The urine collecting device 1 is fitted in the sliding contact state, and the collar 13 of the urine collecting device 1 is brought into contact with the peripheral edge of the opening end of the cylindrical body 22.
[0027]
As a result, the urine collection port 11 of the urine collector 1 fitted into the opening of the cylinder 22 is held in a fitted state by the frictional force between the rib 13a and the inner peripheral surface of the cylinder 22, and the rim 13, the opening of the cylindrical body 22 is sealed.
If necessary, if the elastic ring member 16 is brought into close contact with the inner peripheral surface of the cylindrical body 22, the airtightness can be further improved.
[0028]
The hose 3 has elasticity, but is not particularly limited as long as it is self-supporting enough to be pushed down and not bent, and a conventionally known one may be adopted. Further, the stoppers 31 of the hose 3 are made of synthetic resin having a strong elastic force as shown in FIG. 8, and are formed in an annular shape in which a part is open, and both open ends are required to be spaced apart from each other inside and outside. The engagement pieces 31a and 31b and the presser pieces 31c and 31d are formed so as to overlap each other with a gap therebetween. The meshing pieces 31a and 31b overlap each other inward and outward, and the mutually opposing surfaces form sawtooth teeth that mesh with each other, and the presser pieces 31c and 31d face the inner side or the outer side of the other open ends engaged with each other. Thus, the meshing pieces 31a, 31a are pressed and held in the meshed state from the inside and the outside.
