ABSTRACT:
The present invention concerns a pressure bandage for hip joint prosthesis operated patients and includes a portion which may be enclosed around the hips of said patient.
At prior art pressure bandages of the above mentioned type, it is difficult to inspect inside the bandage and in doing so opening and applying a new bandage again. In the course of a doctor binding up elastic bandages around the hip of the patient in the manner of a skirt/girdle with the appropriate pressure, at the same time six nurses must lift the patient straight up from a bed, which lead to an uncomfortable and detrimental operating position for the nurses, and that valuable time for the doctor is consumed for such tasks. Furthermore, the staff risk getting into contact with the blood of the patient. The pressure which is provided is then not controllable, which might be the cause of bedsore on sensitive patients. It may also be positioned too loosely and will then not have the desired effect, and large haematoma may arise, which may lead to serious consequences, for example infections and unnecessary loss of blood. This may also involve a longer process of healing and pain for the patient. During inspection, the bandages must be removed by cutting off and then they are thrown away in order to if necessary be replaced by new bandages, which leads to high bandage costs.
Through U.S. Pat. No. 4,270,527 is previously known a bandage trouser which is provided with inflatable bladders inside a trouser forming panel. This bandage trouser is in the first place intended for use as an aid of assistance when taking care of injured persons involved in an accident, like e.g. a vehicle accident. It is then important to be able to safely hold injured limbs in place during transport. There is for this object for instance an inflatable pressure bladder which is arranged inside in one of the legs of the bandage trouser. An additionally arranged pressure bladder is arranged inside the bandage trouser in the area around the waist of a patient.
Any effective supporting function for the hip of the patient longitudinally which is needed after a hip operation, is not enabled with the prior art bandage trouser. The fact is that it is very important and crucial with the shape of the supporting means during hip operations in order to get the right pressure to the operated area at the hip joint in order to avoid bleeding but still exert pressure onto the operation area.
The main object of the present invention is therefore in the first case to provide a pressure bandage which solves for instance the above mentioned problems and which also provides a multitude of additional advantages.
The object is achieved by means of a pressure bandage according to the present invention, which is principally characterized in that the enclosing portion is formed by a cloth-shaped inelastic girdle which exhibits Velcro closing means at their away from each other turned with each other—connectable end parts, that a pressure bladder which has an oblong shape tapering in the direction towards one of its short ends, substantially corresponding to the thickness of the patients hip and thigh, as seen when the patient lies on his back and to which means are connected for pressure control and fluid level filling respectively, may be received inside said enclosing and connected girdle, wherein filling and emptying respectively of said pressure bladder enables producing the desired pressure upon the operated hip.
The pressure bandage according to the present invention may be used as a preventive measure, and be used as pressure on tissue during bleeding in progress.
Advantages:
Controlled pressure,
facilitated inspection,
requiring less staff,
reduced risk for staff to come into contact with blood,
reduced cost for bandages,
fewer blood transfusions,
shorter process of healing.
