  BODY FLUID DRAINING DEVICE AND POCKET

COLLECTION PROVIDED WITH SAID DEVICE

  The invention relates to a device for draining bodily fluid, such as urine, as well. a collection bag fitted with this emptying device. After an ostomy surgical operation performed on a patient following a malformation, a tumor or an inflammation of the urethra or the bladder, and in particular after a urostomy, it is advisable to restore the urinary functions in an artificial way, these do not can be performed normally by the body of the operated patient. A hygienic device, comfortable and not disturbing the occupations of the patient, such as work,

  sport or leisure, is therefore provided for this purpose.

  For this, the ostomy patient is generally equipped with a bag for collecting bodily fluid placed immediately after

  lS ['operation, generally around an abdominal orifice for evacuating urine.

  This pocket, conventionally produced in the form of a bag of flexible woven material impermeable to the fluid which it contains, can be removable or else drainable so as to be able to evacuate its contents. In this particular embodiment, it is common to use a drainage device, typically relic in the lower part of the pocket by a neck with reduced section, so that the urine flows under the effect of gravity when the device

  drain is in an open position.

  Different types of pocket emptying device for collecting body fluid already exist commercially. In addition to basic clamp systems which are impractical to use, there are systems which typically use a drain valve located in the lower part of the pocket and which can be handled by the patient or a third party, such as a nurse, with a view to opening or closing a urine drainage channel. Such devices are described in particular in international application No. WO 93 17 642. In this document, the valve is of the rotary type and can in particular take alternately two substantially perpendicular positions, one relative to the other, depending on whether the patient wishes close the drain or open it to drain the urine. Patent No. FR 2 474 858 describes a system comprising a tap intended for closing or closing a drainage channel of a

urine collection bag.

  These devices are not satisfactory in terms of the hygiene of the patients or of the personnel who use them, the safety of the obturation, the ease of grasping, the degree of complexity of the

  manufacturing, discretion or comfort of use.

  The object of the invention is therefore to resolve the drawbacks

evoked above.

  To do this, the invention proposes that the emptying device be produced in the form of an articulated system ensuring better sealing, increased safety, easy and rapid operation, as well

  that improved user comfort in a reduced footprint.

  More precisely, the invention relates to a device for draining a bodily fluid, arranged around a drain orifice for a bag for collecting this fluid, and comprising three articulated shutters consisting of: a first flight substantially annular fixed externally on a wall of the bag and provided with a central opening for the flow of fluid out of the bag; - a second flight hinged to the first via a first hinge, to pass from a first closed closed position, in which it closes the opening of the first flights by covering said opening in a sealed manner, at a second open and raised position, in which it allows the fluid to flow through said opening thus released; and - a third flight hinges on the second flight to pass from a first closed closed position, in which it blocks the second flight in its closed position folded on the first flight by preventing its pivoting, to a second open and raised position, in

  which it unlocks the second flight allowing it to pivot.

  Thus, the second and third flaps form a sealed biocage system with easy leverage to open or close without being

  necessary for the user to make a significant effort.

  According to different preferred embodiments of the invention:

  - the third flight is articulated on the second flight by means of a second hinge, arranged parallel to the first hinge common to the first and second flaps; - The first flight is provided with first blocking means cooperating with the second flight to maintain it in its closed folded position; - The first wind blocking means of the protrusions S normally erected at the annular part of the first flights; - Preferably, the protuberances have a T-shape and wind formed by a foot extended by an enlarged head provided with a first lobe engaged with francs of the second flight to lock it in its closed folded position; - More particularly, the foot of each protuberance is elastically deformable laterally with respect to its direction of elevation; - two identical wind protrusions arranged diametrically opposite on either side of the central opening of the first flight; - The third flight is equipped with second blocking means cooperating with the first blocking means of the first flight to maintain the third flight in its closed position folded over the second flight; - The second opposite lobe of the enlarged head is engaged with the second locking means of the third flight to block the latter in its closed folded position; - the second wind blocking means of the lateral eyelets each having an opening intended to receive the corresponding protuberance; - the third flight has a hollowed-out central zone and is provided with a gripping tab, arranged opposite the second hinge relative to the central zone and oriented towards the hollowed-out zone of the third flight; - the emptying device is made in one piece from injected plastic; - a discharge nozzle is adaptable on the device

  drain when it is open.

  The invention also relates to a collection pocket, adapted to be placed on the abdomen of a patient who has undergone an ostomy operation. This pocket includes the emptying device defined below

  above it has a fluid tight bag through a drain hole.

  Advantageously, the emptying device is welded externally to a film constituting the bag, in an area forming a channel

extension vent.

  In order to make the bag more compact and more comfortable to carry, the area forming a drainage channel is foldable in the closed position under an external covering covering the film on which the film is welded.

emptying device.

  Other features, details and advantages of the invention

  will emerge on reading the description made with reference to the drawings

  appendices given by way of example and in which: - Figure 1, a perspective view of a urine collection bag provided with a drainage device has in a first extreme open position and on which is mounted a nozzle of evacuation; - Figure 2, a perspective view of the drain device in its first extreme open position; - Figure 3, a perspective view of the drain device has in a partially open intermediate position; - Figure 4, a perspective view of the drain device in a second extreme closed position; - Figure 5, a sectional view along the arrows M of Figure 4; and - Figure 6, a sectional view along the arrows BB of the

figure 4.

  Figure 1 shows, in perspective view, a pocket 10 of

  collection of ileostomies according to the invention.

  This pocket 10 is typically constituted by two thin films 12 spaces and welded to each other at their periphery to form a bag 14 impervious to the bodily fluid contained in the pocket, that is to say in the present case of fluid or pasty excrement. A fabric such as cotton, or else a non-woven coating, usually covers the bag 14 for improved wearing comfort, in particular in contact with the patient's belly, in order to avoid irritation due to friction and sweat. The bag 14 ends at a lower end by a zone 16 of reduced section forming an elongated drain channel. This drain channel 16 has a width less than the main width of the bag 14 and slightly greater than the overall width of a drain device 20 welded externally on said bag 14 and

  can be used to empty the contents of pocket 10.

  To this end, the emptying device 20, represented in FIG. 1 in a first raised extreme open position, receives a hollow discharge nozzle 18 making it easier to empty the contents of the

  pocket by gravity, and possibly by pressing the bag 14.

  The emptying device 20, shown in more detail in FIGS. 2 to 6, mainly comprises three flaps 30, 40 and 50 hinges between

  them to allow or not the emptying of the pocket.

  The first voles 30 is welded externally to one of the films 12 of the bag 14. The welding is carried out around a conventional drain orifice (not visible in the figures), fed through the thickness to said film 12. This first flights 30 is of annular shape and has, opposite the emptying orifice of the bag 14, a substantially circular central opening 31 surrounded by a solid annular portion 32, as shown in FIG. 2. This first flights 30 is also provided with first blocking means 33 arranged diametrically opposite on either side of said central opening 31, on the part

full yearbook 32.

  These first blocking means 33 are in the form of protuberances 34 which stand up normally normally from the surface of the annular part 32 of the first voles. Check protuberance 34 has a substantially straight foot 35 extended by an enlarged head 36 provided of two lobes 36a and 36b so as to present a substantially T-shape, as shown in particular in FIGS. 2 to 6. The foot 35 is deformable elastically laterally from its main direction

  of elongation, as illustrated by the arrow F in FIG. 5.

  The second part 40 is articulated on the first part 30 a

  ['using a first hinge C1 located on an edge of the second voles 40.

  This hinge allows the second flights 40 to pass alternately from a first closed closed position, in which it covers in a fluid-tight manner the central opening 31 of the first flights 30 using a membrane 42 as shown. in FIGS. 3 and 4, at a second raised open position in which it allows the fluid to flow through said opening 31, as shown on the

Figures 1 and 2.

  To allow the second flights 40 to be kept in the closed position on the first flights 30, as illustrated in FIG. 4, the franks 43 of the second flights 40 cooperate with the lobes 36a of the protuberances 34 with

  which they wind in order to form elastic locking clips.

  The third voles 50 is articulated on the second voles 40 by means of a second hinge C2 arranged on an edge opposite to that where the first hinge C1 is located. This second hinge C2 allows the third flights 50 to pass alternately from a first closed closed position in which it blocks the second flights 40 in its closed position 10 folded over the first flights 30 by preventing its pivoting, as illustrated in FIG. 4, towards a second raised open position in which it unlocks the second flights 40 by allowing it to pivot, as illustrated in

Figures 1 and 2.

  The third voles 50, also of annular shape with a hollowed-out central zone 56 to reduce the weight of the emptying device, is provided with second locking means 51. These second locking means 51 are constituted by projecting lateral eyelets 52 each presenting a central opening 53 for the passage of the first biocage means 33, including the enlarged head 36. The opening 53 of the eyelets is bordered by a zone of material 54, substantially in the form of a loop, intended to come into engagement with the lobes 36b of the protuberances 34. The third voles 50 is thus blocked on the first voles 30, and the membrane 42 of the second voles 40 compressed on the central opening 31 of the first voles 30. It is then guaranteed

  good sealing of the drainage device.

  The third voles 50 is also provided with a grasping tab 55 arranged opposite the second hinge C2 and directed towards the

hollow area 56.

  The discharge end piece 18 shown in FIG. 1 can be temporarily fixed on the first flights 30, for example by

  cooperation with the first blocking means 32.

  The zone 16 forming an elongated drain channel can, when the drain device 20 is completely closed, be folded under the covering covering the film 12 on which the drain device 20 is welded. Thus, the drain device 20 is protected by this coating, does not overflow

  bag 14 and therefore does not interfere with the patient carrying pocket 10.

  As can be seen in particular in FIGS. 5 and 6, the total thickness of the emptying device 20 is very small, of the order of a few millimeters, making it particularly compact and therefore easy to carry since it is not very troublesome for the patient. Furthermore, this emptying device 20 is made of a single plastic material, for example a polymeric material molded by injection, which makes its manufacturing process

  particularly fast and economical.

  The use of this emptying device 20 is very simple, hygienic and manageable. The patient wishing to empty the bag 10 grasps the gripping tab 55 by passing a doipt underneath. He raises it to tilt the third voles 50 around the second hinge C2. The lower shape of the lobes 36b and the elasticity of the foot 35 wind such that it suffices to pull hard enough on the gripping tab 55 so that the second biocage means 51 disengage from said lobes 36b. However, the effort to be made by the patient is relatively low since the blocking force is distributed between

the second and third parts.

  Once the third flights 50 is raised, as illustrated in FIG. 3, the patient lifts the second flights 40 to tilt it around the first hinge C1. For this, the patient disengages the first blocking means 33 so that the franks 43 are no longer engaged with the lobes 36a of the protrusions 34. This operation is facilitated by the leverage and multiplication of the forces provided by the third flights 50 on the second flight 40. The patient therefore does not have to make a significant effort to

lift the second flight 40.

  In this raised position of the second flights 40, as illustrated in FIG. 2, the membrane 42 no longer closes the central opening 31 of the first channel 30 and the bodily fluid can be evacuated from the bag 14. This evacuation takes place from preferably after having mounted the nozzle 18 on the first blocking means 33 of the first voles 30, as illustrated in the

figure 1.

  It should be understood, however, that this exemplary embodiment is given solely by way of illustration of the object of the invention, of which it in no way constitutes a limitation. In particular, the central opening of the first flights 22 can be elliptical, oval or any suitable oblong shape. Furthermore, the blocking means may have other shapes and their number may vary. The emptying device as described above can also be used on a

  collection of urine or other physiological effluents.
