A mode of use of the urine suction device 1 configured as described above will be described with reference to FIG.

FIG. 5 shows an example in which the urine suction device 1 according to the present invention is used by attaching it to a wheelchair (care product) 25. The reserve tank 4 is attached to the frame portion 37 below the push handle 36 to generate negative pressure. The casing 20 of the part 2 is installed at a portion where the seat part 38 and the column 39 of the hand-held handle 36 intersect, and the urine receptacle 6 is attached to the urine discharge port 15 of the person 41 who uses the care vehicle 35.

[0023] At this time, although not shown in the figure, an attachment such as a string or rubber is provided at the upper end of the urine receiver 6, and the urine receiver 6 is fixed to the person 41 who uses this wheelchair with this attachment. This will prevent them from slipping even when the body moves.

When the urine suction device 1 is equipped with a manual switch, the manual switch is attached to the armrest part 42.

[0024] When a person wearing the urine receiving device 6 has a urinary intention, the manual switch is turned on to activate the electric motor 21 of the negative pressure generating unit 2 to drive the suction pump 23. Release to Keg 6

When urine is released to the urine receptacle 6, the urine detector 18 detects this, and the electric motor 21 of the negative pressure forming unit 2 is activated by the detection signal from the urine detector 18 to drive the suction pump 23. It is.

The suction negative pressure generated by driving the suction pump 23 is supplied to the reserve tank 4 through the negative pressure supply pipe 3 to make the inside of the reserve tank 4 a negative pressure. When the pressure in the reserve tank 4 becomes negative, the urine in the urine receptacle 6 is sucked into the reserve tank 4 through the suction tube 5 and stored by this negative pressure.

When the urine in the urine receptacle 6 runs out and the urine detector 18 does not detect urine for a certain period of time (for example, about 3 seconds), or the timer has passed a predetermined period of time (for example, 30 seconds). Then, power supply to the electric motor 21 is stopped, and urine suction is finished.

[0026] Thus, when a predetermined amount of urine is aspirated into the reserve tank 4 and the detection sensor 34 detects the exchange or discharge timing, the lid 8 of the reserve tank 4 is removed, and the urine is stored. Body part 7 is removed from care vehicle 35 and urine is discharged.

At this time, if a joint 43 is provided in each of the suction pipe 5 and the negative pressure supply pipe 3 as shown by a two-dot chain line in FIG. 1, by separating the joint portion, the care vehicle 35 of the reserve tank 4 is provided. It can be made easy to remove.

[0027] In the above embodiment, the force of the urine receptacle 6 for men in the figure is not limited to this, and the urine suction device 1 for women can be obtained by changing the shape. In addition, the type of the pump section 24 of the suction pump 23 in the above embodiment is not limited to the diaphragm type, and it is possible to use a vane type pump, a plunger type pump or other pumps as well as a negative pressure with an ejector or a jet pump. The forming unit 2 can be configured, or the suction pump 23 can be one.

In addition, the suspension piece 30 for suspending or fixing the casing 20 in the above embodiment can be replaced with a plate-like object and can be a string or a hook, or can be fixed with an adhesive or the like.

Example 2

[0028] The urine suction device 1 of this example is obtained by changing the reserve tank 4 in the first embodiment as shown in FIGS. 6 to 9, and is sucked into the reserve tank 4 as shown in FIG. A storage bag 45 for storing urine is detachably attached to the lower side of the lid 8.

The reserve tank 4 is composed of a container-like main body portion 7 and a lid body 8 that closes the upper end opening of the main body portion 7 in an airtight manner in the same manner as in the first embodiment. A connecting portion 46 to which the end of the suction pipe 5 connected to the receiving device 6 is connected is formed, and a negative pressure supply port 47 to which the negative pressure supply pipe 3 is connected is formed on the side thereof. A urine suction passage 48 is formed between the urine receptacle 6 and the connection portion 46, and a female screw 49 to which a urine storage bag 45 is screwed is attached to the end of the suction passage 48 on the reserve tank 4 side. Is formed.

The urine storage bag 45 is a flexible and flexible sheet, formed in a watertight bag having a cylindrical suction port 50 in the upper opening, and formed in the suction path 48 on the outer periphery. A male screw 51 is formed, and an orifice (small hole) 52 for forming a differential pressure is formed on one side (surface in the drawing) in the vicinity of the suction port 50.

Here, the orifice 52 is for sucking urine into the storage bag 45 together with a large amount of air from the suction pipe 5 while inflating the storage bag 45. The orifice 52 is used in the storage tank 45 for pressure (P1) and in the reserve tank. A differential pressure such that P1> P2 is formed between the outer peripheral portion of the storage bag 35 (P2).

Therefore, it is desirable that the opening area of the orifice 52 be Sl, the passage sectional area of the suction port 50 be S2, and the passage sectional area S3 of the negative pressure supply port 47 be SK S3 and S2. At least Sl≤S3 must be satisfied.

In this example, the orifice 52 is formed on one side (surface in the figure) near the suction port 50 of the storage bag 45. The force is not limited to this, and it is formed so as to penetrate the front and back of the storage bag 45. can do. In this case, the opening area S1 of the orifice 52 is the sum of the opening areas on the front and back sides.

[0031] Furthermore, a drug 60 such as a granular gelling agent or thickener is enclosed in the urine storage bag 45 of this example.

As an example of the drug 60 such as the above-mentioned gelling agent or thickener, there is a gelling agent described in JP-T-2005-533134, for example.

Incidentally, the drug 60 described in the above publication is a gelling agent, a thickening agent, and a gelling agent or a thickening agent 60 can be encapsulated alone or in combination. Instead of this, or together with this, a water-absorbing resin as described in JP-A-2000-79159 can be encapsulated.

In the urine suction device 1 of this example, first, the lid body 8 having the storage bag 45 attached to the end portion of the suction path 48 on the reserve tank 4 side is attached to the main body portion 7. Next, as in Example 1 above, when a person wearing the urine receptacle 6 makes a urine intention, the manual switch is turned on to activate the electric motor 21 of the negative pressure forming unit 2 and drive the suction pump 23. The urine is released to the urine receptacle 6 as it is.

The suction negative pressure generated by the drive of the suction pump 23 is supplied to the reserve tank 4 through the negative pressure supply pipe 3 to make the inside of the reserve tank 4 a negative pressure.

Due to the negative pressure in the reserve tank 4, the urine receiving force 6 released to the atmosphere via the suction pipe also sucks urine together with a large amount of air into the storage bag 45.

At this time, in the urine storage bag 45, the air sucked into the storage bag 45 by the orifice 52 formed on the surface thereof is restricted from flowing out to the outer peripheral portion of the storage bag 45, or the opening area of the orifice 52 is increased. Since the flow resistance is received even when S1 is equal to the passage cross-sectional area S3 of the negative pressure supply port 47, the pressure in the storage bag 45 (P1) and the pressure in the outer periphery of the storage bag 45 in the storage bag 45 with little resistance to inflating A differential pressure such that P1> P2 occurs between (P2) and the urine storage bag 45 is maintained in an inflated state.

Therefore, the urine sucked into the urine storage bag 45 together with a large amount of air is gelled by the gelling agent or the agent 60 such as a sticking agent in the storage bag 45 and only the air is stored from the orifice 52. It flows into the reserve tank 4 outside the bag 45, and this force is also sucked into the suction pump 23 through the negative pressure supply pipe 3 and discharged.

When a predetermined amount of urine is sucked into the storage bag 45 and gelled with a drug 60 such as a gelling agent or a viscous agent, the male screw 51 and the female screw 49 of the suction port 50 are unscrewed and the storage bag is released. 45 is removed from reserve tank 4.

Thus, the storage bag 45 taken out from the reserve tank 4 can be treated as non-burnable garbage or industrial waste when a cap 53 is attached to the male screw 51 of the suction port 50 as shown in FIG.

In this example, the urine storage bag 45 is attached by fitting the male screw 51 formed at the suction port 50 to the female screw 49 formed at the end of the suction path 48. This force is shown in Fig. 9 As shown in Fig. 4, the female screw 49 of the suction path 48 is made into an annular protrusion 54 for locking, and the suction bag 50 is formed by the flexible tube 55 and the suction bag 50 of the storage bag 45 is formed. It is also possible to attach the storage bag 45 by inserting it into the annular projection 54 of the passage 48.

In this case, instead of the cap 53, the tube 55 is bent and fixed with a clip 56 or the like and sealed.

The orifice 52 can seal the storage bag 45 containing urine by sticking a sealing tape 57 thereto.

[0036] Power! If you make at least a part of the urine storage bag 45 transparent and paste it on the inside of the transparent part where it touches the urine, you can see the change in the paper and manage your health. Can be easily performed.

Furthermore, since the urine receiver 6 of each of the above embodiments is formed of a flexible material such as silicone resin, or a flexible sheet material is molded, the burden on the wearer with very little discomfort is reduced. It can be done by adhering directly to the skin, omgu, underwear, etc. with an adhesive like a euro bag.

[0037] The urine suction device 1 of the present invention is not limited to the nursing care illustrated in FIG. 5, but can be used during sports such as long-distance driving golf.

Furthermore, the power source 22 is not limited to a dry battery, and a commercial power source can be used.
