Description

Pants-shaped mesh bandage for dressing wound of lower limb amputation stump

technical field

The utility model relates to a medical bandage, in particular to a trousers-shaped mesh bandage used for dressing a wound of a lower limb amputation stump.

Background technique

In clinical work, clinicians are often faced with situations that require treatment of the wounds of the thigh amputation stump. High-energy trauma, severe electrical burns, vascular occlusion, tumor surgery and other reasons can cause damage, necrosis, and destruction of the lower limbs. Patients need to undergo amputation surgery to avoid greater damage to the body. It usually takes 14 days for the stitches to be removed after the amputation stump. During this period, the wound needs to be bandaged to protect the wound and avoid wound infection. Moreover, in the treatment of trauma and burn patients, because of the combined skin and soft tissue damage, physicians often adopt the treatment strategy of open amputation in order to preserve the length of the limbs, that is, for the amputation wounds that are difficult to be sutured directly, not too much to accommodate the skin conditions. The femur is removed, and the stump of the femur is embedded with healthy muscle tissue in the first-stage operation, while the wound remains temporarily; after the infection is controlled, the second operation is performed to cover the wound with autologous skin grafting to achieve healing. In order to ensure the cleaning of the wound and the survival of the skin graft, not only a longer time of bandaging is required, but also higher requirements are placed on the strength, duration, and topical medication of the wound.

At present, the bandaging of the stump of the thigh amputation is still covered with cotton pads, and the elastic bandage is the main bandage. Clinicians often use multi-layer bandages, annular bandages to the waist and abdomen, and auxiliary adhesive tapes to avoid bandages from loosening. However, the stump of the thigh amputation is an irregular columnar structure with a thick upper and a thinner lower. If only a bandage is wrapped around the wound during wound treatment, the dressing will be very easy to "take off socks" when the patient performs activities such as turning over, sitting up, and getting down. Falling off leads to exposure of the wound surface, which not only easily causes wound surface infection and increases the risk of infection, but also leads to necrosis of the grafted skin on the skin grafted wound surface, and also increases the number of unnecessary dressing changes, increases the suffering of patients, and increases hospitalization costs. For example, the use of repeated wrapping and joint bandaging of the waist can reduce the probability of falling off to a certain extent, but because of increasing the thickness of the wrapping and wrapping the abdomen in a circular shape, it has disadvantages such as enhancing the patient's discomfort, restricting abdominal breathing, and affecting sit-up activities. The combined method of adhesive bandaging, although reliable, requires several strong adhesive strips to be attached to the dressing and normal skin at the same time, which increases the risk of skin allergy to the adhesive and tension blisters. In addition, the skin is oily and sweaty in summer, the adhesive strip is easy to loosen, and it is difficult to play the role of a fixed dressing. Therefore, the problem of loose bandaging of the amputation stump is very common in clinical practice, and there is currently no suitable product to solve it.

Utility model content

In view of the problems existing in the prior art, the present utility model provides a trousers-shaped mesh bandage for dressing the wound of the lower limb amputation stump, which has a simple structure, is convenient to use, and is firmly bound, and can properly wrap the dressing on the thigh amputation stump without the need for adhesive tape.
