    URINE MEASURING DEVICE
    FIELD OF THE INVENTION
    [0001] The present invention relates to a urine measuring container.
    BACKGROUND OF THE INVENTION
    [0002] To observe urinary function of postoperative patient, a healthcare staff often uses urine measuring container to see the urination volume produced by patients within a specific period or during a single urination as a reference of the postoperative recovery status. The conventional urine measuring container has a drip chamber, a check valve and a measuring chamber. The urine flows into the drip chamber via a catheter and then flow into the measuring chamber through the check valve. The healthcare staff read a scale on the measuring chamber to gain the urination volume of the postoperative patient.
    [0003] However, in the practical usage of the conventional urine measuring container, there exists a problem of inaccurate measurement of the urination volume since the measuring chamber cannot be replenished with air, which leads to negative pressure in the drip chamber relative to the pressure in the measuring chamber to cause the urine to be blocked by the check valve and remained in the drip chamber. In addition, there is possibility that the urine accumulated in the drip chamber flows back to the catheter, which raises the risk of urinary tract infection.
    SUMMARY OF THE INVENTION
    [0004] Accordingly, an object of the present invention is to provide a urine measuring device which can accurately measure the amount of urine produced by patients.
    [0005] To solve the issues in the prior art, the present invention provides a urine measuring device, comprising: a container body having a drip chamber and a measuring chamber, wherein the drip chamber and the measuring chamber are vertically adjacent when being in a suspended state, and an adjacency on which the drip chamber and the measuring chamber are abutted is provided with a liquid through hole vertically passing through the drip chamber and the measuring chamber, in which the drip chamber communicates with the measuring chamber via the liquid through hole; and a valve member having a counterbalance component and disposed in the liquid through hole which is controlled to be open or closed by the valve member, wherein when being the suspended state, the valve member controls the liquid through hole to be open by the gravitational force of the counterbalance component.
    [0006] According to an embodiment of the present invention, the valve member includes a membrane having a moving portion and a fixed portion surrounding the moving portion, wherein the moving portion completely covers the liquid through hole when the valve member is closed, and the counterbalance component connects to the moving portion.
    [0007] According to an embodiment of the present invention, the moving portion connects to the fixed portion, and the counterbalance component connects to a peripheral section of the moving portion, wherein the peripheral portion is located in a position opposite to a connecting section between the moving portion and the fixed portion.
    [0008] According to an embodiment of the present invention, the peripheral section has a moving portion hole, and the counterbalance component has a protuberance provided to lock into the moving portion hole.
    [0009] According to an embodiment of the present invention, the counterbalance component is welded to connect to the peripheral section.
    [0010] According to an embodiment of the present invention, the adjacency at which the drip chamber and the measuring chamber are abutted is provided with a fixing protuberance component, and the fixed portion includes a fixed portion hole through which the fixing protuberance component penetrates through the fixed portion.
    [0011] According to an embodiment of the present invention, the fixing protuberance component and the fixed portion hole are respectively plural and are equal in number, and the position of the plural fixing protuberance component and the position of the fixed portion hole form a poka-yoke configuration.
    [0012] By the technical means adopted by the present invention, the weight of the counterbalance opens the liquid through hole when the urine measuring device is in the suspended state. Accordingly, the air in the drip chamber and air in the measuring chamber can mutually communicate, which prevents the formation of negative pressure in the drip chamber, and the urine in the drip chamber can thus be emptied completely, which enables accurate measurement of the urination volume.

    DETAIFED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    [0014] The preferred embodiments of the present invention are described in detail below with reference to Fig. 1 to Fig. 6. The description is used for explaining the embodiments of the present invention only, but not for limiting the scope of the claims.
    [0015] As shown in Fig. 1 to Fig. 6, a urine measuring device 100 according to an embodiment of the present invention comprises: a container body 1 having a drip chamber 11 and a measuring chamber 12, wherein the drip chamber 11 and the measuring chamber 12 are vertically adjacent when being in a suspended state, and an adjacency on which the drip chamber 11 and the measuring chamber 12 are abutted is provided with a liquid through hole 13 vertically passing through the drip chamber 11 and the measuring chamber 12, in which the drip chamber 11 communicates with the measuring chamber 12 via the liquid through hole 13; and a valve member 2 having a counterbalance component 21 and disposed in the liquid through hole 13 which is controlled to be open or closed by the valve member 2, wherein when being in the suspended state, the valve member 2 controls the liquid through hole 13 to be open by the gravitational force of the counterbalance component 21.
    [0016] The urine measuring device 100 of the present invention is generally hung beside a patient’s bed when being used, and is disposed vertically along the direction of the gravity force. The urine flows downward into the drip chamber 11 from above. The adjacency on which the drip chamber 11 and the measuring chamber 12 are abutted forms a wall portion 14 where the liquid through hole 13 is disposed. The valve member 2 and the wall portion 14 form a check valve of the urine measuring chamber 100, which allows the urine to flow unidirectionally from the drip chamber 11 into the measuring chamber 12. Specifically, the check valve is a single plate check valve.
    [0017] As shown in Fig. 1 and Fig.2, in the urine measuring device 100 according to the first embodiment of the present invention, the valve member 2 has a membrane 22 which is a thin elastic plastic plate disposed in the measuring chamber 12. The membrane 22 has a moving portion 221 and a fixed portion 222 surrounding the moving portion 221. In this embodiment, the moving portion 221 and the fixed portion 222 of the membrane 22 is delimited by a C-shaped hole 223, wherein an end of the moving portion 221 is connected to the fixed portion 222. The moving portion 221 is a thin round plate, and the liquid through hole 13 is a round through hole. The area of the moving portion 221 is larger than the cross-sectional area of the liquid through hole 13, and the moving portion 221 covers the liquid through 13 hole when in a non-suspended state. It goes without saying that the moving portion 221 and the liquid through hole 13 can be in other shapes. The present invention is not limited to this.
    [0018] As shown in Fig. 2 and Fig. 3, in the urine measuring device 100 according to the first embodiment of the present invention, the counterbalance component 21 connects to a peripheral section of the moving portion 221, wherein the peripheral portion is located in a position opposite to a connecting section between the moving portion 221 and the fixed portion 222. As shown in Fig. 5, when being suspended state, the weight of the counterbalance component 21 produces a torque bending the connecting section between the moving portion 221 and the fixed portion 222 of the membrane 22. The weight of the counterbalance component 21 needs to be big enough so as to resist the viscous force and the surface tension of the urine when the membrane 22 is soaked by the urine so as to prevent the moving portion 221 from sticking to the wall portion 14.
    [0019] In this embodiment, the counterbalance component 21 has a protuberance 211 provided to lock into a moving portion hole 224 of peripheral portion of the moving portion 221. As shown in Fig.4, in the urine measuring device 100a according to the second embodiment of the present invention, the counterbalance component 21 is welded to connect to the peripheral section and is integrally formed. It goes without saying that the present invention is not limited to this. The weight of the counterbalance component 21 can be transferred to the moving portion 221 by sticking the counterbalance component 21 to the moving portion 221, or by kinetically connecting the counterbalance component 21 to the moving portion 221 via a lever, or via other kinetic connection methods.
    [0020] As shown in Fig. 2 and Fig.3, the adjacency on which the drip chamber 11 and the measuring chamber 12 are abutted is provided with a fixing protuberance component 141 that extends downward from the wall portion 14 and penetrates through a fixed portion hole 225 of the fixed portion 222. It goes without saying that the present invention is not limited to this. The fixed portion 222 of the membrane 22 can be stuck or welded to the wall portion 14. The fixing protuberance component 141 and the fixed portion hole 225 are respectively plural and are equal in number. The positions of the plural fixing protuberance component 141 and the positions of the fixed portion hole 225 are unsymmetrical, forming a poka-yoke configuration. Specifically, the fixing protuberance component 141 and the fixed portion hole 225 are disposed at three non-collinear positions with different distances from each other. Accordingly, the fixing protuberance component 141 and the fixed portion hole 225 can only be assembled in one direction so as to avoid mistakes while assembling.
    [0021] As shown in Fig. 5, in the urine measuring device 100 according to the embodiment of the present invention, the separation of moving portion 221 from the wall portion 14 enables the air in the drip chamber 11 and the air in the measuring chamber 12 to communicate via the liquid through hole 13 so as to prevent the formation of negative pressure in the drip chamber 11. The urine can flow into the measuring chamber 12 without obstruction of the moving portion. By comparing the urine level in the measuring chamber 12 with a scale on a transparent cover 15 of the container body 1, the amount of the urine can be accurately measured.
    [0022] As shown in Fig. 6, when the urine measuring device 100 is in the non-suspended state, such as being in a tilted position, a flat position, or an inverted position, the moving portion 221 leans towards the wall portion 14so as to cover the liquid through hole 13 with the help of the pressing force caused by the weight of the counterbalance component 21 and the urine, and/or the effect of resilience of the moving portion 221 itself so as to block the urine, which prevents the urine from flowing back to the drip chamber 11. Preferably, the density of the counterbalance component 21 is larger than the density of the urine. When the urine measuring device 100 is inverted, the weight of the counterbalance component 21 which is submerged in urine can assist the moving portion 221 to cover the liquid through hole 13. In other embodiments, the liquid through hole 13 is open and without being covered by the moving portion 221 when the urine measuring device 100 is in the non-suspended state such as being in a tilted position or in a flat position.
    [0023] The above description should be considered as only the discussion of the preferred embodiments of the present invention. A person having ordinary skill in the art may make various modifications to the present invention. However, those modifications still fall within the spirit of the present invention and the scope defined by the appended claims.
