Definitions

• a hose clamp for an outlet hose member from a liquid collection bag is provided.
• the invention relates to a hose clamp to be positioned on an outlet hose member inserted at the bottom of a liquid collection bag between welded wall portions of the bag, comprising two clamp parts that are hingedly connected at one end and one of which is provided with a jaw part that is eccentric about the hinge axis and, in the closing position of the clamp, squeezes the hose member against a stationary jaw part on the second clamp portion, the clamp parts having releasable locking means active in the closing position.
• Such hose clamps are mainly used in liquid collection bags for medical or hygienic purposes, e.g. urine collection bags for incontinence equipments.
• the hose clamp according to the invention is characterized in that said second part has a substantially U-shaped cross-section corresponding to the outer diameter of the hose member and having lateral portions in which opposite longitudinal slots for receiving said welded wall portions of the bag are provided, said slots extending from the end opposite the hinge connection through such a length of the clamp that only a slight portion thereof around the jaw parts projects outside the edge of said wall portions.
• one of the clamp portions as a Ushaped member which on the major part of its length by means of said slots is pushed onto the welded bottom walls of the bag so that only a very small portion of the clamp projects outside the bag, entails a considerably improved comfort to the user.
• FIG. 1 shows a hose clamp according to the invention mounted on a urine collection bag
• Figs 2 and 3 are perspective views of the hose clamp in open and closed positions, respectively, Fig. 4 is a longitudinal view, and
• Fig. 5 illustrates the hose clamp from one end.
• the urine, collection bag shown in Fig. 1 is of a conventional design with resilient walls made from plastic material, said walls being welded together in a liquidtight manner at lateral portions 2 and 3, a bottom portion 4 and a top portion 5, an outlet hose member 6 and an inlet hose member 7, respectively, being inserted, however, between the welded bag walls at the bottom portion 4 and the top portion 5, of which the inlet hose member may for instance be connected with an external catheter of the kind disclosed in published international patent application No. WO 86/00816.
• a hose clamp 8 to be further described in the following is mounted around the outlet hose member 6.
• the clamp 8 In the illustrated mounted position the clamp 8 is pushed onto the bottom portion 4 of the bag 1 surrounding the portion of the outlet hose member 6 located between the bag walls so that only a very little portion of the clamp 8 extends outside the bag 1.
• the clamp 8 comprises two clamp parts 9 and 10 that are hingedly connected at the one end which in the mounted position of the clamp projects outside the bag.
• the first hinge part 9 is provided with a jaw part 11 which is eccentric with respect to the hinge axis and, in the closing position, squeezes the hose member 6 against a stationary jaw part 12 on the second clamp part 10.
• the clamp part 10 has a substantially U-shaped cross-section cor responding to the outer diameter of the hose member 6 and includes lateral portions 13 and 14 in which longitudinal slots 15 and 16 are provided to receive the bottom portion 4 of the bag 1, said slots extending from the end edge 17 opposite the hinged connection through such a length, of the clamp 8 that only a slight portion thereof around, the hinge connection projects outside the bag 1 as illustrated in Fig. 1.
• the bottom 18 of the U-shaped clamp part 10 may be provided with upwardly projecting, longitudinal ribs 19 serving as guide members for the hose member 6.
• the lateral portions 13 and 14 of the U-shaped clamp part 10 and inwardly projecting edge portions 20 and 21 of the clamp part 9 are provided with engaging parts which in the illustrated example are constituted by inwardly projecting edge portions 22 and 23 and underlying, longidtudinal rib projections 24 and 25 on the lateral portions 13 and 14 and parallel to said edge portions, and by outwardly projecting protuberances 26 and 27 at the free end of each of the edge portions 20 and 21 of the clamp part 9.
• Said engaging parts provides for obtaining in the closing position a reliable snap locking engagement between the clamp parts 9 and 10, the external surface of the clamp part 9 flushing substantially with the top edges of the lateral portions 13 and 14 of the clamp part 10.
• the clamp part 9 may at its end opposite the hinge connection be formed with an outwards directed bulge 28 constituting a handy finger grip.
• the hinge connection between the clamp parts 9 and 10 is provided by engagement between inwardly projecting hinge pins 29 and 30 on the lateral portions 13 and 14 of the clamp part 10 and matching recesses 31 in the external surface of the clamp part 9 at the jaw part 11.
• the clamp part 9 comprises a conical depression 33 which in the open position of the hose clamp with the clamp part 9 turned substantiality 180° in relation to the closing position, causes that the squeezing effect on the hose member becomes minimum, thereby ensuring a maximum free liquid flow through the hose member when emtying the bag 1 through the hose member.
• Each of the clamp parts 9 and 10 may be formed in one piece, for instance from an injection moulded plastic material.
