Description

 The present invention relates to a compression device for birds in order to practice on them a surgical, veterinary or care procedure and a compression table equipped with at least one device according to 1 invention.

 Contention devices for birds are already known. These devices consist of a tablet on which the volatile is immobilized by elastic straps. It has become clear to use that this type of device cannot ensure perfect immobilization of the bird.

 In addition, certain surgical acts such as the capping require two surgical operations carried out one after the other which each require a new positioning of the poultry on the tablet. After the first intervention, a person skilled in the art will have to handle the poultry to reposition it on the shelf.

It has been observed that during this manipulation, in the event that the artery was slightly injured during the removal of the testicle, any sudden movement of poultry results in the worsening of the artery injury causing rapid death of poultry.

 Usually capering operations are performed on a large number of poultry for a relatively short period of time and in most cases the restraining device usually used is not cleaned after each surgical procedure, so there is a high risk contamination of poultry by contact with the restraint tablet are incurred.

 The object of the present invention is to provide a solution to the above-mentioned problems by proposing a restraining device capable of firmly holding the poultry and which is orientable so as to be able to position the poultry adequately in the operating field without it be necessary to separate it from its restraining device.

 To this end, the bird restraint device, in accordance with the invention, for practicing on them a surgical, veterinary or care procedure is essentially characterized in that it comprises, integral with the same common support, at at least a first retention means in which at least one of the legs of the volatile is blocked, a second retention means disposed at a distance from the previous one and in which the wings of the volatile are blocked by their humeral region, and at least one element of 'support or cradle in the form of an arc arranged between the first and second retention means with spacing between them and in which the bird is supported by its posterior dorsal zone, and that at least one of the retention elements is mounted in guidance on the support in a movable manner with respect to the other and is urged apart from the other by at least one elastic member so that the volatile is placed in extension between the first means and r extension and the second while being wedged in particular in the cradle.

 According to another characteristic of the invention, the first and second retention means as well as the arc cradle are each separated from the support and each secured to the end of a rod which is specific to it, secured to the support.

 It is therefore understood that the bird is placed spaced from the support so that its contact with the restraining device is limited to the only means of retention and the cradle only.

 According to another characteristic of the invention, the device by its support is secured, with the possibility of orientation in space and locking in the chosen position, of a fixed element constituting the main support.

 In this way, it is possible to orient the bird as desired while keeping it firmly attached to the restraining device.

 Other advantages and characteristics of the invention will appear on reading the description of a preferred embodiment given by way of non-limiting example with reference to the accompanying drawings in which - Figure 1 is a front view of 'a device according to the invention, - Figure 2 is a perspective view of a device according to the invention, a bird being shown in thin dashed line.

- Figure 3 is a half view of a compression table.

 The compression device 1 according to the invention for birds 2 in order to perform a surgical, veterinary or care procedure on them, comprises, integral with the same common support 3, at least one first retention means 4 in which is blocked at least one of the legs of the bird, a second retention means 5 arranged apart from the previous one, and in which the wings of the volati are blocked by their humeral region and at least one support element 6 or cradle in the form arc, disposed between the first and second means 4 and 5 for retaining the spacing thereof and in which bears the bird by its posterior dorsal area.

 Preferably, one of the two retention means 4 or 5 is mounted as a guide on the support, movably relative to the other and is urged apart from the other by at least one elastic member 10 so that the volatile is placed in extension between the first retention means and the second while being wedged in particular in the arc-shaped cradle.

 It is therefore understandable that this device allows excellent immobilization of the volatile.

 According to the preferred embodiment, the first and second retention means as well as the cradle 6 in an arc are each separated from the support and are each secured to the end of a rod 7 or 8 or 9 which is specific to it, secured to the support.

 It can therefore be seen that this arrangement makes it possible to separate the volatile from the support and to reduce the size of the contact surfaces between the volatile and the device.

Such an arrangement is therefore, to a certain extent, conducive to reducing the risks of contamination of poultry by contact with the device.

The rods 7, 8 and 9 are all arranged along the same geometric plane and the first retention means 4, the second retention means 5 and the cradle 6 in the form of an arc each develop symmetrically with respect to said plan.

 According to the preferred embodiment, the first retention means 4 is mounted movably relative to the support 2 while the second 5 is fixed, but according to an alternative embodiment, the second retention means is movable relative to the support while the first is fixed.

 Preferably, the first retention means 4 is guided in rotation relative to the support 3, the rod 7 which carries it being articulated to the said support and being engaged with an elastic member 10 secured to the support, the said member being under stress between the said support and said rod so that the latter and the retention member that it carries tend to deviate angularly from the other retention means.

 The axis of articulation of the rod 7 to the support 3 is perpendicular to the plane along which the rods 7, 8 and 9 develop.

 The rod 7 of the first retention means 4 is extended beyond its articulation to the support 3 in order to cooperate behind the support with the elastic member 10.

This arrangement allows the elastic member 10 to be removed from the volatile.

This elastic member will advantageously be constituted by a spring with contiguous turns.

This spring by one of its ends will be fixed at the end of the rod 7 and by its other end to a lug of the support.

 The articulation of the rod 7 to the support 3 is formed in a yoke 11 of a slide 12 mounted in attachment to the support with the possibility of adjusting its spacing from the rod 8 of the second retention means.

According to this embodiment, the support is tubular and the slide 12 carrying the yoke 11 is slidably mounted in the support with the possibility of locking in position.

 To block the slide 12 according to the chosen position, a pressure screw will be provided coming into pressure on the slide.

This screw will be engaged in screwing in a thread made in the tubular support.

 The longitudinal median axis of the tubular support 3 will be contained in the geometric plane along which the rods 7, 8 and 9 develop.

 The first retention means 4 is constituted by a cross member 13 fixed at the end of the rod 7 and by fingers 14 fixed by one of their ends to said cross member perpendicularly to the latter, said fingers 14 being spaced from each other by so as to determine between them intervals in which the legs of the bird are blocked.

 The cross member 13 develops perpendicular to the rod 7 and equally on either side of the terminal section of the latter.

 Preferably, the means 4 has a central finger 14 perpendicular to the cross member and two lateral fingers developing obliquely with respect to the cross member and each defining with the central finger an interval widening progressively from the cross member towards their free end.

 Preferably, the fingers will be covered with a soft material in order to avoid injuring the bird.

 The second retention means 5 comprises a crosspiece 15 fixed perpendicularly at the end of the rod 8, two lateral holding elements 16 fixed perpendicularly at the end of the crosspiece 15 and defining with said crosspiece a general "U" shape intended to receive the dorsal area of the volatile, and two hook shapes 17 fixed to said crosspiece intended to receive in locking the wings of the volatile, said hook shapes each being fixed at the end of said crosshead and being angularly offset relative to the holding elements lateral.

 The cross member 15 extends perpendicularly to the rod 8 equally on either side of the terminal section of the latter.

 The lateral retaining elements each consist of a rectangular tab having two folds so as to form with the other lateral retaining element a gap widening progressively from the cross member 15 to the second fold then remaining constant up to the free end of said elements 16. These two lateral holding elements 16 in combination with the cross member 15 form a stirrup intended to be engaged around the dorsal region of the bird, below the humeral joints.

 The two hook shapes 17 are fixed to the ends of the cross-member 15.

These two hook shapes are each formed by a rod having a right angle bend for example, so as to have a first straight segment 17A and a second straight segment 17B, perpendicular to each other and linked to each other. the other by the bent part.

 By considering the direction of positioning of the bird in the device, the hook shapes 17 are arranged in front of the elements 16 and the straight segment 17A, by the free end of which each hook shape is fixed to the cross member 15, determines with the said elements 16 an obtuse angle. In addition, the second rectilinear segment of each hook shape is oriented towards the support 3. Finally, it should be noted that each hook shape develops along a geometric plane parallel to the geometric plane along which the rods 7, 8 and 9 develop. .

The first two rectilinear segments 17A determine an interval in which the two wings of the bird are engaged simultaneously.

 The blocking of each wing in the corresponding hook shape is effected by engagement of its cubital area through the angle formed by the first and the second segment 17A and 17B and by pressing in the hollow of the bent part and against the second segment outside the interval between the two hook shapes 17.

 The arc-shaped cradle is obtained by bending a thin metal strip into an arc around the circumference. This cradle by its central region is fixed to the rod 9. This rod is fixed to the support 3 obliquely to the longitudinal axis of the said support 3 and inclines towards the rod 8 of the second retention means 5. De more, the geometrical plane containing the arc of circumference along which the cradle in the form of an arc develops contains the axis of the rod 9. This arrangement which leads to the inclination of the cradle, takes account of the anatomical profile of the bird.

 The rod 9 can be constituted by a tubular sheath and the cradle can be fixed to a slide mounted with sliding play in the sheath so that the cradle can be moved more or less away from the support. A pressure screw associated with the sheath and cooperating in pressure with the slide will maintain the cradle in the chosen position.

 This arrangement is likely to improve the adaptability of the device to the anatomical profile of the bird.

 The device as described is, by its support 3, secured to a fixed element, constituting a main support and this with the possibility of orientation in space and locking in position.

 According to the preferred embodiment of the support 3 along the plane of the rods 7, 8 and 9, the first and second retention means and the cradle 6 is fixed a tubular arm 18 capable of sliding in rotation on a cylindrical pivot 19 comprising a member stop 20 limiting the angular movement of the device around the axis of the arm so as to allow the position of the device to be inverted by pivoting around the axis of the pivot 19 and its maintenance according to the chosen position.

 The pivot 19 is fixed to a structure and constitutes with the latter the abovementioned main support.

 Preferably, the tubular arm 18 is perpendicular to the support 3 and is fixed to one of its ends. In addition, the arm 18 and the pivot 19 are horizontal.

Thus, the center of mass of the device is offset relative to the axis of the arm 18 and of the pivot 19, which ensures self-maintenance according to one or the other position in space.

 The abutment member 20 is constituted by a pin projecting from the pivot. This pin is engaged in an oblong lumen made at the end of the arm along an axis of circumference of a circle.

 Advantageously, the device as described can be used in the context of the capping operation and allows the positioning of the poultry on one side and the other.

Capaging operations are usually carried out on a very large number of poultry for a limited period of time.

It is therefore advantageous to provide for the use of several devices in accordance with the invention which may be grouped on a table comprising a vertical, cylindrical column 22, on which a hub 23 is rotatably mounted comprising a plurality of radial pivots 19 for receiving several restraining devices.

Thus by rotation of the hub, each device 1 can be brought successively to several work stations.

 Below the devices 1 and at a distance from the latter will be disposed a first shelf with rim and above the devices 1 a second shelf intended to receive the various surgical, veterinary and other instruments.

 It should be noted that the shelves are crossed by the column 22 and are fixed to the latter.

 It should also be noted that the lower shelf has a small area so as to be set back towards the column with respect to the devices 1. In this way, any blood flow and other natural flows cannot come onto the lower shelf and contaminate the objects placed there.

 Above each workstation, the table may include light sources.

 At least the parts of the device 1 intended to be in contact with the volatile will be made of stainless steel.

 The device according to the invention can receive all arrangements and all variants without departing from the scope of this patent.

 Thus the two retention means 4 and 5 can be movable relative to the support.

 Likewise, the retention means 4 may be movable in translation and no longer in pivoting and will include guide members known per se, mounted to slide in a rectilinear manner in elements of the support.

 Furthermore, the arm 18 can be linked via a ball joint to a main support so as to allow the orientation of the device by pivoting around the three axes of the space.
