Problems solved by technology

[0009] Impossible to detect the value and uniformity of the applied pressure: some bandages therefore run the risk of being applied too tightly, causing pain, or not tightened enough, losing their effect
[0010] In practice, in the period immediately following surgery, patients often suffer far more from poorly placed bandages than the surgery itself

Embodiment Construction

[0031] figure 1 The orthosis of the present invention is shown, basically a stocking that is open in the foot. Rather, the appliance 10 is a knitted tube with variable sections that conforms to the shape of the leg, ie tapers downward, preferably without a knitted foot or heel.

[0032] This appliance is used to cover the lower body from the foot to the base of the thigh, such as figure 2 with 3 shown.

[0033] It must be able to exert constant pressure on the lower limbs from the ankle to the thigh (while the pressure on conventional elastic stockings decreases from the ankle), the pressure should be about 30mmHg-40mmHg (40.0 hectopascal (hPa)-53.2hPa ), thus exerting a constant hemostatic effect along the entire lower extremity.

[0034] The tubular appliance 10 comprises two substantially semi-cylindrical sections 12 and 14 which extend along the entire length of the appliance and which are connected together along generatrices 16 and 18 at opposite ends of a diameter ...

Abstract

The orthosis comprises a compressive tubular portion (10) of knitted or woven fabric, of varying section that matches the profile of the lower limb, and in which the knit or weave structure is selected as a function of the peripheral dimensions of the lower limb so as to apply compression pressure of about 30 mmHg to 40 mmHg that is substantially constant along the length of the limb. The tubular portion extends from the foot to the top of the thigh and comprises a stretchable inner region (12) that is highly elastic and that is connected along two generator lines to an outer region (14) that is non-stretchable or poorly stretchable. The top end of the orthosis is also provided with a thigh sleeve (22) that is open along a generator line and that is provided with adjustable closure means (24).

Description

field of invention [0001] The present invention relates to the field of compression appliances for use in the period immediately following lower extremity vein surgery. Background of the invention [0002] Superficial vein surgery includes two major procedures, both of which involve the surgical removal of diseased veins. [0003] The first procedure is called "dissection," and it involves stripping the internal or external saphenous vein with wires. The procedure is performed under anesthesia, which can be general, local, epidural, or tranquillized. It causes severe damage to the collateral branches of the saphenous vein, causing bleeding, causing hematoma, and the patient is painful and uncomfortable for hours and days after the procedure. [0004] Another technique commonly used is outpatient phlebectomy, which is a less invasive procedure than dissection (but can also be performed before and after dissection). The technique involves complete aspiration of superficial ...
