Description Urine measuring device

The invention relates to a urine measuring device which is used in particular for measuring the amount of urine in infants and small children.

State of the art:

The patent document DE 29 00 806 was found to be the state of the art, in which a general device for collecting a body fluid is described. Furthermore, the document DE 30 07 855 was found, which describes a device for measuring the urine flow of a patient, which consists of a measuring sensor provided with a funnel for feeding the urine, arranged inside a housing, and an evaluation unit. The measuring sensor consists of a U-shaped measuring tube mounted so that it can swing freely inside the housing. The document DE 31 14 524 was also found, in which a urine measuring device is shown in which a measuring vessel is equipped with a deflector. The patent document DE 38 37 856 describes a urine meter which consists of a rigid collecting and measuring container and a flexible container directly next to it, whereby the liquid from the measuring container can be tipped into the flexible container. According to patent DE 43 38 687, a urine measuring device is presented in which, among other things, a correction of the value determined by the force transducer is carried out for each level in a calculation device using trigonometric functions. Patent DE 195 48 678 describes a urine measuring device in which a flexible inner hose element, around which liquid can flow, is arranged coaxially in the drain hose. The urine measuring device according to DE 195 48 689 is characterized in that the urine collection container with the force transducer (measuring unit) is suspended on a gimbal at the bottom of the device housing.

The disadvantage of all the above-mentioned inventions is that, on the one hand, they are not suitable for measuring the smallest quantities of liquid due to their dimensions and, on the other hand, they involve a high material expenditure.

The invention is based on the problem of creating a measuring device that can be manufactured simply and with little material expenditure, that is suitable for possible suction and extraction and with which small quantities of liquid can be measured.

This problem is solved with the features listed in claim 1.

Example:

An embodiment of the invention is explained in more detail with reference to the figure.

The figure shows a view of the entire measuring device.

A cylindrical, transparent drip chamber 1 with a conical outflow side 2 is provided with a graduation 3 for measuring urine. The drip chamber 1 is made from elastic but dimensionally stable material. This elastic drip chamber 1 makes it possible to pump or suck out urine. The drip chamber 1 is a relatively small vessel that is adapted to the amount of urine of a small child, and the graduation 3 is also provided with a fine division according to the small amount of liquid, so that even the smallest amounts can be read precisely. Due to the dimensionally stability of the material, the measuring accuracy of the drip chamber 1 is always guaranteed, which cannot be guaranteed with the unstable measuring bags. A lid 4 is arranged opposite the conical outflow side 2 of the drip chamber 1. The lid 4 is assigned a non-return valve 5 so that no urine can flow back into the area in front of the drip chamber 1, thus ensuring that any possible migration of germs is stopped. Furthermore, a liquid-repellent, inert degassing filter 6 is arranged in the lid 4, which is provided with a filling level tube 7 in the lid 4 in the direction of the drip chamber 1, so that the liquid level in the vertical position of the drip chamber 1 can only reach a predetermined level that lies below the non-return valve 5, thereby creating a dry zone 8. Openings 9 are also provided in the lid 4 for attaching a holding device. For suction, the elastic drip chamber 1 is compressed, whereby the non-return valve 5 is closed and air escapes from the degassing filter 6. Due to the vacuum created in the drip chamber 1, which returns to its original shape, urine can be suctioned out of the bladder. A hose 10 is pushed onto the check valve 5 or a hose connection arranged in the cover 4, which can be closed with a hose clamp 11 attached to it. This hose 10 is connected at the other end to a urine collection point 12. A hose 13 is arranged on the other side of the urine collection point 12, which in turn is connected via an elastic stepped cone 14 to a catheter hose 15 suitable for babies and small children, whereby the catheter hose 15 is inserted directly into the opening corresponding to the hose thickness.

because the prepared opening of the stepped cone 14 or by means of a cone attached to the catheter tube is arranged on it. A shut-off valve 16 with a Luer/Lock connection is attached to the conical outlet side 2 of the drip chamber 1. A subsequent urine measuring bag 17 or simple urine bag is connected to the shut-off valve 16 via a Luer/Lock connector 18. The figure shows the separate version. The urine measuring bag 17 is also provided with a graduation and a degassing filter 6, in which larger quantities of urine can be collected. On the one hand, the drip chamber 1 can be "filled" or emptied thanks to the shut-off valve 16, and on the other hand, the filled urine measuring bag 17 can be easily and quickly separated from the measuring device after the shut-off valve 16 has been closed using the Luer/Lock connector 18 and a new urine measuring bag 17 can be connected.
