URINE COLLECTING AND MEASURING DEVICE

Abstract: A device for collecting and measuring urine from a patient and including a stiff transparent measuring container (1) divided into several adjacent graduated chambers (2, 3, 4), which at the top are open to each other and having lower outlet openings (16, 17, 18), which by way of a valve device (19) are connected to an outlet (15), to which a collecting container, for example a urine bag, is connected. An inlet (5) is connected to the first chamber (2) and an overflow (20) connected to the outlet (15) is arranged after the last chamber (4). In order to make the measuring container as simple as possible to manufacture and consisting of as few parts as possible and besides provide an even weight distribution at the filling of the container the first chamber (2) is arranged centrally in the measuring container (1) and has on different heights arranged overflows (8, 9) to both on either sides located second and third chambers (3, 4) which with a portion (13, 14) each extended behind the first chamber (2). The outlet openings (17, 18) from the second and the third chambers (3, 4) are located behind each other on either sides of the partition wall (14) between them and behind the outlet opening (16) of the first chamber (2).

Description: URINE COLLECTING AND MEASURING DEVICE TECHNICAL FIELD The present invention refers to a device for collecting and measuring urine from a patient and comprising a stiff transparent measuring con-tainer divived into several adjacent chambers, which at the top are open to each other and having lower outlet openings which by the way of. a valve means are connected to an outlet to which a collecting container for exampel a urine bag, is connected at which an inlet is connected to the first chamber and an overflow connected to the outlet is arranged after the last chamber. BACKGROUND OF THE INVENTION Through the US-A 4.265.188 a urine measuring device of the above mentioned kind is known. The inlet to the measuring container is connected to a chamber at one of the sides of the container and when the first chamber is filled the urine will flow throw an overflow over to a second adjacent chamber and when this chamber has also been filled the flow will continue to a third chamber by way of the overflow and so on. The disadvantage with this device is the uneven weight distribution wich appears in the measuring container when it is gradually getting filled up with urine from one chamber to the other. In case of insufficient fixation of the measuring contanier, the container will therefore slant which makes it impossible to make a correct reading. The measuring container is also relatively complicated to produce, since it consists of several parts which has to be glued together. THE PURPOSE AND THE MOST IMPORTANT CHARACTE ISTICS OF THE INVENTION The purpose of the present invention is to provide a measuring container of the above mentioned kind which is considerably easier to produce. It should consist of as few parts as possible and the interior of the measuring container should be so constituted so that it can preferably be shaped with one single moulding tool by means of injection moulding. The measuring container should besides be so constructed that a more even weight distribution should be obtained when filling the container. These problems have been solved by the fact that the first chamber is arranged centrally in the measuring container and has on different heights arranged broad overflows to both on either sides arranged second and third chambers, which with a portion each are arranged to extend from behind the first chamber, and that said outlet openings from the second and third chambers are located behind each other on either sides of the partition wall between them and behind the outlet opening of the first chamber. • DESCRIPTION OF THE DRAWINGS The- invention will in the following be described more in detail with reference to the enclosed drawings showing an embodiment. Fig. 1 shows the measuring container in a front view. Fig. 2 is a section according to the lines 11- 11 in fig. 3 r Fig. 3 shows the measuring container from above, Fig. 4 shows a front view of a suspension device for the measuring container, Fig. 5 shows the suspension device in a side view, Fig. 6 shows a twopiece design of the suspension device in a front view. Fig. 7 shows the suspension device according to ig. 6 in a side view. DESCRIPTION OF AN EMBODIMENT The measuring container 1 is manufactured of a stiff transparent plastic material and is divided into three graduated measuring chambers 2,3 and 4 which are open to each other. An inlet 5 for the urine is connected to the first centrally located chamber 2. The inlet is arranged in a lid 6 closing the measuring container 1. The lid shows futher a filter-provided vent opening 7, through which the displaced air can pass out of the container 1. The first chamber 2 has two on different heights arranged overflows 8 and 9 in the respective partition walls 10 and 11 to the second and third chambers 3 and 4 so that when the first an second chambers 2 and 3 are filled the third chamber 4 will start to be filled through the overflow 9. The second and third chambers 3 and 4 extend with a portion 12 and 13 each behind the first chamber 2 and the partition wall 14 therebetween is consequently arranged behind the first chamber. The partition wall 14 is shaped, so that out-let openings 16.17 and 18 from from the first, second and third chamber respectively 2,3 and 4 placed in the bottom of the measuring container 1 and connected to an outlet 15 could to place behind each other along an essentially straight line. The outlet openings 16-18 are opened and closed simultaneously by means of a valve 19. An overflow 20 from the third chamber 4, is furthermore arranged in connection to the partition wall 14 which overflow by way of an outlet opening 21 communicates with the outlet 14. The outletopening 21 is always open independent of the position of the valve. A collecting container (not shown) for exampel a urine bag, should be connected to the outlet 14. The bag can be suspended on hooks 23 on the suspension device 24 of the measuring container 1. The suspension device 24 is shown in detail in fig .4 and 5 and comprises a vertical part in the form of a pair of resilient shanks 26, provided with outer cogs 25 and which at the upper end terminates into hooks 27 intended to be hooked to a bed for exampel. The shanks -25 can spring into a groove 28 on the backside of the measuring container 1 provided with corresponding inner cogs 29, so that a locking of the suspension device 24 to the measuring container 1 can be provided in optional position. The suspension device 24 presents at the bottom a horizontal portion 30 with a plurality of hooks 23 for suspending urine bags in different sizes . The heavy urine bag will with this construction not hang in the measuring container 1 but in the suspension device 24, which is to prefer. In ig. 6 and 7 is shown a two-piece design of the suspension device 24, in which each part has a pair of resilient shanks 26a and b provided with a cogged portion each 25a respective b. The position to the hooks 24 can be adjusted to suit different suspension alternatives. The measuring container 1 can be manufactured by means of injection moulding of few parts and the complete interior can be shaped in one step with one injection tool, this since both the partition walls 10, 11 and 14 and the outlet openings 16-18 and 20 are reachable from above before the lid 6 is installed and fixed to the measuring container. The invention is of course not limited to the presented embodiment but a plurality of modifications are possible within the scope of the following claims.
