Definitions

  • the invention relates to a cla p for detachably mounting a device on a preferably annular implant by means of a clamping force and of the kind that has two arms each defining a jaw and a handle, a hinge designed in the area between the jaws and the handle for pivotally connecting the arms to each other, and a clamp spring for clamping the jaws to each other.
  • an ostomy pouch can in some designs have coupling parts for coupling the pouch to corresponding couplings parts on an adhesive face around a stoma.
  • the coupling means on the ostomy pouch can be used for coupling with an annular implant but are not directly designed for this exact purpose. Therefore, the ostomy pouch cannot always be fastened securely to the implant and can in these cases therefore not form a completely tight sealing with this implant. For example, small difference in diameter can be the cause of a loose coupling which cannot ensure effectively against leakage.
  • a second object of the invention is to provide a clamp that can be manipulated by a person having little finger strength.
  • a fourth object of the invention is to provide a clamp that is provided with a sealing ring for sealing with the implant.
  • clamp spring is designed as a spring ring with a cross slit and is serving for fastening the device to the implant in mounted state, and that the jaws are pivotally connected with the spring ring.
  • the clamp and a possible associated device such as e.g. an ostomy pouch which can be completely or partly integrated with the clamp, are mounted quickly and easily on e.g. an annular implant.
  • the clamp fits closely and tightly around the implant without use of locking means which are difficult to manipulate especially for a person having weak fingers and are difficult to see in details for a person having failing eyesight.
  • the spring ring and the arms of the clamp can be made in one piece, the jaws and the spring ring then being pivotally connected to each other via two integral hinges, and the hinge of the arms being a second integral hinge.
  • This embodiment of the clamp can expediently be made of a plastic such as polypropylene, nylon or similar relatively hard, dimensionally stable, inexpensive, high-molecular polymers that are elastically deformable.
  • a clamp designed with integral hinges in one piece with the spring ring can easily be injection-moulded. Therefore, the components of the clamp do not have to be joined by separate parts by e.g. welding or bonding. Thereby, price-raising finishing is avoided. Furthermore, the free movement of the integral hinges is enabled and not hindered by neither adhesive residues or welding burrs. Furthermore, there is no risk of the clamp breaking by accident at weakened or exposed points of joining when the clamp is spring loaded during mounting or dismounting.
  • the spring ring can actually have any cross section that can engage with and be received by a groove designed correspondingly in the implant but in an especially preferred embodiment, the cross section can be mainly rectangular in order to thereby eliminate the risk of the ring buckling during the mounting operation.
  • the spring ring does not necessarily have to be designed to fit completely or partly in a corresponding groove. Instead, it can quite simply clamp around a cylindrical part of the implant.
  • the ring can maintain a mainly circular configuration in all positions and affect the implant with the same clamping power along the entire periphery.
  • the clamp can advantageously be provided with a sealing ring serving for forming sealing between the implant and the device and advantageously made of an elastomer which for example can be a rubber .
  • the sealing ring forms an elastic bridge across the cross slit of the spring ring so that an effective clamping effect between the spring ring and the implant is also obtained in this area.
  • the clamp can advantageously be used for coupling the implant to e.g. a commercially available ostomy pouch designed with a groove around the ostomy opening for receiving the clamp.
  • the spring ring can be cast together with the sealing ring in a casting process where the sealing ring is made to adhere to at least a part of the spring ring for example the radial inside face of the spring ring.
  • the clamp will take up the least possible room.
  • the arms are easy to manipulate by means of the handles which can be designed with different sizes depending on the actual needs so that e.g. a person having little finger strength can find a rest for his finger tips.
  • the two first integral hinges can be at the inside face of the spring ring and form part of the spring ring on either side of the cross slit. Thereby, the structure becomes compact.
  • each of the jaws can furthermore have a length of between V-, and 2, preferably between x h and Vh- times and especially between % and VA times the radial thickness of the spring ring. These dimensions are such that the spring ring can open sufficiently upon mounting to allow it to be guided in over the implant without difficulty and then clamp securely and firmly around this implant.
  • the arms can be between VA- and 10, preferably between 2 and 7 and especially between 2 and 5 times the length of the jaws.
  • the clamp is given a ration of transmission which advantageously can be used to open a strong and effectively functioning spring ring with even modest finger strength.
  • the clamp according to the invention can be placed inside an ostomy pouch in such a way that the spring ring is fastened along the edge of the ostomy aperture of the pouch.
  • an edge area at the ostomy aperture of the ostomy pouch can be bent in over and fastened along the radial inside face of the spring ring.
  • the edge area will function as the sealing mentioned above upon mounting of the ostomy pouch on the annular implant.
  • Such a fabricated ostomy pouch with integrated clamp is easy and inexpensive to manufacture by means of known techniques. Further, the pouch is simple and quick to mount on and dismount the implant.

  • the clamp can however be used with just as great advantage for many other devices, of which examples are wigs for mounting on a bald pate, tubes for e.g. rinsing of a faeces reservoir of a patient with implant made in connection with a sto a, or in general for tubes which are to be clamped around another part.
  • the simple clamp 1 in fig. 1 is made of a spring ring 2 passing into two projecting arms 4 at a cross slit 3, said arms are partly interconnected by a integral hinge 5, partly connected with the spring ring via integral hinges 6.
  • the arm are designed with jaws 7 and handles 8 serving as rest to fingers when the clamp 1 is to be mounted on an annular implant or taken off this implant.
  • the handle 8 of the clamp 1 is actuated with a pressing force in the direction of the arrows, that is in a direction towards each other, the spring ring 2 is opened to a size that is sufficiently great for the spring ring to be guided in over an implant (not shown) .
  • the clamp 9 in fig. 2 corresponds mainly to the embodiment shown in fig. 1, and like parts are therefore referenced similarly.
  • the only difference is that the handles 10 are designed with a greater contact face to conveniently be able to press the handles together with the fingers.
  • the clamp 9 is seen with a sealing ring 11.
  • the sealing ring has an outer part 12 and an inner part 13.
  • the outer part 12 has a greater outside diameter than the inner part 13, the outside diameter of which corresponds to the inside diameter of the spring ring 1.
  • the inner part 13 is embedded along the inside periphery of the spring ring 1 and spans the cross slit 3.
  • the sealing ring has a circumferential projection 14 serving for engaging with a groove in the implant 15 in fig. 4.
  • the circumferential projection 14 of the inner part therefore has a thickness that mainly corresponds to the height and depth of this groove. This appears more clearly from the cross section of the clamp 9 mounted on the implant 15 in fig. 5.
  • the sealing ring is made of an elastic material, such as rubber, which easily yields to the movement of the spring ring during mounting and dismounting.
  • the sealing ring 11 will advantageously settle as a tight, elastic sealing between the implant and the spring ring.
  • Fig. 5 shows, taken along the line V-V of fig. 4, the clamp 9 with a sealing ring 11, mounted on the coupling part 18 of a commercial ostomy pouch 19.
  • the outer part 12 is designed with a radial thickness and a diameter respectively that are suited for this part to be pressed into the groove 17 on the coupling part 18 of the ostomy pouch 19.

  • the radial thickness is relatively great.
  • the width of the groove 17 of the coupling part 18 is small, and the outer part 12 is then designed with correspondingly small dimensions .
  • the clamp 9 of fig. 3 with an embedded sealing ring 11 is shown as illustration example mounted on the implant 15 known from the Danish patent application no. DK/PA 2000 00521.
  • the circurmferential projection 14 is received in the groove 16 of the implant 15.
  • the implant 15 is not part of the scope of the present invention and will therefore not be mentioned any further here.
  • the clamp 1 is placed inside an ostomy pouch 20 at the ostomy aperture 21 of this pouch.
  • a part of the pouch material at the opening 21 is bent in over the top of the spring ring 2 and down along its inside face where the pouch material is securely fastened and is serving as an expedient sealing.
  • the ostomy pouch is made of a flexible plastic such as e.g. polyethylene which can resist great tensile stresses without breaking or weakening.
  • Such a material is especially expedient as it can yield to the different shapes of the spring ring when the ring's diameter is increased during mounting and dismounting of the clamp.
  • the arms of the clamp 1 are positioned in such a way that they mainly face upwards when the ostomy pouch is in use. This position makes it easy for the patient to get hold of the handles of the arms.
  • the clamp can alternatively be welded or bonded to the inside of the ostomy pouch along a free outer side and subsequently be provided with a sealing ring of an elastomeric material along the inside periphery. Combinations where the sealing ring is consisting of both pouch material and an extra rubber sealing is also possible within the scope of the invention.
  • Figs. 7 and 8 show a clamp 22 with a bow 23 having a length greater than the largest possible distance between the handles 8 of the arms 4 and furthermore sufficiently great for the bow to press the arms 4 so far apart that the spring ring 2 can be opened sufficiently to be guided down over the implant.
  • Fig. 7 shows the open spring ring 2 with the bow 23 pressed down between the arms in the direction of the arrow.

  • this embodiment can be mounted inside and be integral with an ostomy pouch and just as the clamps 1 and 9, it can be provided with a sealing ring 12.
  • the clamps 22 are very useful to a person who, due to weak finger strength or reduced sense of touch in the finger tips, has trouble in overcoming the reaction of the spring power of the spring ring when the person is to press the handles 8 together with the fingers upon mounting of the clamp.
  • the clamp 1 is shown in an embodiment where the aperture is covered with a cover 24.
  • a clamp arranged in such a way will give a unique possibility of closing the stoma/the free discharge of the implant into the surroundings and will give the user a new and hitherto unknown freedom of movement to e.g. go in for sports without at the same time being handicapped by a full ostomy pouch.
  • Fig. 10 is a sectional view taken along the line X-X of fig. 9.
  • the clamp is provided with a sealing ring 25 along the inside periphery of the spring ring.
  • the sealing ring is serving for ensuring that the clamp can be clamped optimally on an implant.
