Definitions

  • This invention relates to compression of artery in general, and in particular to a device for compression of the radial artery at the inner wrist after punction.
  • the main problem with the known devices and methods is that the devices when applied, hinder the flow of blood to and from the extremities, e.g. foot and hand, which may be experienced as painful to the patient, and could also have negative medical effects if the period of applying the pressure is extended, such as a few hours or more. Such extended time is often necessary in order to allow the tissue to heal sufficiently.
  • US-5,263,966 discloses a wrap which covers the groin area to support a specifically shaped pressure baloon.
  • EP-A1-0554602 (Sumitomo Rubber Ind. Ltd) discloses a corapressi- ve hemostatic belt comprising an inflatable baloon, mounted on a specific position of a strip of fiber cloth.
  • the object of the invention is to provide a device of aforem ⁇ entioned type that overcomes the drawbacks of the prior art devices. In particular it is desired to shorten the time needed for hospitalization of patients after catheterization. It is also desired to provide simpler wound care after punction of artery. Hematoms should also be prevented or eliminated if possible.
  • a device comprising a pressure distribution and support member or plate provided on the side opposite to the punction site, whereby a local pressure applied to a compression element, placed over the punction, will be dis ⁇ tributed over a large surface on the opposite side. Thereby the pressure on the veins will not be high enough to block the return flow of blood from e.g. the hand.
  • the pressure distribution plate is bent such that the hand is fixed in a bent position when the device is applied. Thereby access to the radial artery is made easier and also healing after punction is facilitated.
  • the invention also provides a method of achieving local hemo- stasis of selected artery, e.g. the radial artey at the wrist, while maintaining blood flow through the surrounding artery and through the veins.
  • the compression device of the invention is defined in claim 1, and the method of the invention is defined in claim 9.
  • Preferred embodiments are defined in the dependent claims.
  • Fig. 1 shows a perspective view of the device in detail
  • Fig. 2 shows a cross section through a wrist with a device according to the invention applied thereto;
  • Fig. 3 is a perspective view of a device according to the invention applied to a patients wrist.
  • Fig. 1 there is shown a preferred embodiment of the device according to the invention, generally designated 1. It comprises a pressure distribution and support plate 2, a plurality of securing straps 3a-c, and a compression element 4, slidably connected to one of the straps 3c.
  • the plate 2 is anatomically designed to fit exactly to the outer or top side 5 of the wrist 6. Especially there is provided a "dent” or “dimple” to accomoda- te the small “knuckle bone” at the wrist (caput ulnae). Further ⁇ more the plate 2 is bent at the actual site of the wrist joint (shown with a B in the drawings), such that it enables the wrist to be supported by the pressure distribution plate and maintained fixed in a bent position.
  • the pressure distribution plate is preferably made of a semi-rigid material such as polyethylene, but other materials are contemplated, e.g. metals such as aluminium. However, any material that is rigid enough to maintain the wrist and hand in a fixed, bent position will be adequate for the purpose of the invention.
  • the rigid pressure distribution plate may be provided with a soft layer 7 of a foam material, such as polyurethane foam.
  • the pressure distribution plate 2 is provided with three securing straps 3a, 3b, 3c, provided with coupling means for securing the device to the wrist and hand.
  • the coupling means may be Velcro R fastenings, or other suitable means, such as buckles or hooks or the like.
  • the first strap 3a is provided on the distal part of the pressure distribution plate 2, for securing the fingers and palm of the hand in a backwardly bent position. The bending is advantageous i.a. in that it exposes the radial artery, thereby enabling punction of the artery.
  • the second strap 3b is provided at the proximal end of the pressure distribution plate 2 for securing the pressure distribution plate 2 to the lower part of the forearm.
  • a third strap 3c provided at the actual bend.
  • a compression element 4 Said compression element is elongated and extends in the direction of the artery. It has preferably a slightly rounded contact surface in order to smoothly bear on the skin.
  • the shown compression element 4 has two flanges 8 each having a slot 9 through which the strap 3c is passed, to provide a sliding attachment of said compression element 4 to said strap 3c. Thereby the element 4 may be adjusted to be positioned exactly where the radial artery is situated.
  • the compression element 4 is preferably made of a soft plastic material such as EVA, but pads made of other soft materials are also possible.
  • the pressure distribution plate 2 exhibits a bending angle of approximately 30°. This angle may however be varied and is not critical to the function. The main reason for providing a bend is to facilitate penetration for catheterization purposes, since the artery will be better exposed when the wrist is bent.
  • At least one of the side walls or side supports 10a, 10b of the pressure distribution plate 2 extends upwards from the bottom portion 11 of the pressure distribution plate, such that there will be a space between the wrist 6 and at least the third strap 3c when the latter is tightened.
  • the compressive force induced by tightening the strap 3c will cause only the compression element 4 to bear against the wrist, i.e. the radial artery in the wrist, and thereby efficiently hinder the blood flow therein.
  • the ulnar artery will still carry an undisturbed flow of blood, thereby supplying blood to the hand.
  • the side support 10a remote from the radial artery will act as counter element to support the wrist under the pressure exerted by the compression element 4.
  • the compression element will preferably have a major force component deviating from the perpendicular, as indicated with arrows in Fig. 2, such that the wrist will actually bear against said remote side wall 10a. Furthermore, the total compressive force exerted by tightening the straps will be efficiently distributed over the back side of the wrist and hand and the lower part of the forearm by the pressure distribution plate 2, such that venous blood flow will be practically undisturbed. Thereby one avoids any pain or other adverse medical effects caused by stoppage of blood flow to and from the hand.
  • the second important effect of tightening the straps such that the hand is fixed in a bent position is that the patient will be prevented from flexing the wrist.
  • the invention provides a method of achieiving local hemostasis of selected artery, in a preferred embodiment the radial artery, while maintaining blood flow through surroun ⁇ ding artery and veins, in the preferred embodiment through the ulnar artery and through the veins in the hand and wrist.
  • the method comprises applying a local pressure to a selected point or area on the selected (radial) artery at a limb (the wrist) of a patient, by means of a compression element.
  • the applied pressure may be provided by straps wound around the limb (wrist) whereby the counterpressure is accomodated on the opposite side by a pressure distribution or support plate having a large surface area, such that the counterpressure is distributed over the entire surface of the back side of the limb (wrist).

Abstract

La présente invention concerne un dispositif (1) pour supprimer le saignement au niveau de la blessure faite par l'introduction d'un cathéter dans l'artère radiale du poignet (6) d'un patient. Le dispositif comprend un élément de compression allongé (4), une plaque (2) de répartition de la pression et de support disposée essentiellement sur les deux côtés du poignet (16) par rapport audit élément de compression (4) et une ou plusieurs courroies (3a, 3b, 3c) pour tenir en place ledit élément de compression (4) et ladite plaque (2) de répartition de la pression. La plaque (2) de répartition de la pression et de support a une portion de fond (11), une première paroi latérale (10a) et une seconde paroi latérale (10b). La première plaque latérale (10a) a une hauteur dépassant l'épaisseur du poignet. La plaque (2) forme un angle pour permettre au poignet (6) d'être tenu solidement dans une position pliée. L'élément de compression (4) est fixé d'une manière coulissante à une des courroies (3c) pour pouvoir le positionner latéralement à différents emplacements sur le poignet (6).
