Binding dressing specially used after limb dismemberment surgery

Abstract

The invention discloses a binding dressing specially used after limb dismemberment surgery. The binding dressing is characterized in that a sleeve with one closed end is included; a pasting membrane of a semipermeable membrane is arranged on the outer side of the sleeve; an adsorption tray is arranged outside the position, at the closed end of the sleeve, of the pasting membrane, a through hole is formed in the position, corresponding to the pasting membrane, of the adsorption tray, and a negative pressure suction pipe on the adsorption tray penetrates through the through hole to continuously provide negative pressure suction for the sleeve; the stump end of an amputated limb is sleeved with the sleeve, the pasting membrane wraps the sleeve, continuous negative pressure suction is carried out by the negative pressure suction pipe, a barrel-shaped composite nano-silver poval sponge is tightened under the action of the negative pressure, the even compression function is formed on the stump end of the limb, the whole wounded part can be in contact with the dressing, the dressing has the strong and broad-spectrum infection resisting function, the good promoting function on the union of a wound is achieved, the percolate of the wound flows out of a drainage pipe, and the wound is kept clean.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a special dressing after limb amputation. Background technique [0002] Limb amputation is a common clinical operation, and postoperative dressing is a very important part. The existing postoperative bandaging is usually to place a drainage sheet at the surgical incision, and then pressurize it with gauze and bandage. But this kind wrapping method has the following disadvantages: [0003] 1) The pressure distribution is uneven. The traditional bandaging method exerts pressure along the radial direction of the limb, while there is almost no pressure in the cross-section of the amputated limb. [0004] 2) The pressure is difficult to control. The traditional bandaging method is difficult to precisely control the pressure. If the pressure is too small, it will not be possible to pressurize to stop bleeding, and if the pressure is too high, it will easily le...
