Description

A kind of flexible interlayer protective device

technical field

The utility model relates to a flexible interlayer protection device, in particular to a flexible interlayer protection device for preventing pressure damage caused by "prone position ventilation".

Background technique

In the intensive care unit (ICU patients with pneumonia infection, patients with respiratory distress, hospital respiratory ward, geriatric ward chronic obstructive emphysema, etc., in order to improve oxygenation, improve hypercapnia, improve right heart function and benefit Lung protective ventilation, intensive care unit (ICU) medical staff and rehabilitation therapists cooperate with family members to perform prone position ventilation treatment on conscious critically ill patients, that is, "tummy time" treatment. Effectively improve the lung ventilation/blood flow ratio, and the airway The secretions of the patient are also well drained. Medical staff, respiratory rehabilitation therapists, nurses, and family members will place pillows on the head, neck, chest, hips, and calves to suspend the knee and/or elbow joints to prevent Soft tissue pressure injury around the knee joint and/or elbow joint. However, patients who have been ventilated in the prone position for a long time (at least 12 hours a day) have bony protrusion, malnutrition, etc. Relieving bony protrusion without a soft support surface is harmful In the case of pressure on the corresponding body surface, the blood circulation of local tissues is blocked, ischemia and hypoxia, and the skin is affected by moisture and friction for a long time, resulting in skin pressure injury (commonly known as pressure sore) and the degree of disuse after pressure Nerve injury (such as ulnar nerve injury). For example, the knee supported by a pillow will still sink, and after the protruding patella and medial tibial condyle are compressed, the surrounding soft tissues will appear soft tissue pressure damage due to compression; Elbow joints can also suffer from skin pressure injuries, etc. In addition, most of the critically ill patients have underlying diseases and elderly patients, who themselves have chronic knee osteoarthritis, knee varus deformity, lymphedema, and vascular neuropathy, etc. The above patients have different degrees of malnutrition, and diseases such as hypoproteinemia have aggravated the probability of secondary damage.

The air bed solves this problem by inflating, but it has the disadvantages of easy air leakage and uneven decompression. The skin and muscles around the knee joint are weak; and it is impossible to prevent the huge bony protrusion of the patella and the uneven bony protrusion when the patella and the medial condyle of the tibia are excessive.

Preferably, the positive Velcro strip and the negative Velcro strip are respectively fixed on the two ends of the outer surface of the first high elastic cotton layer.

Preferably, the first high-elastic cotton layer has a cambered structure when unfolded, and a bent structure when in use, and the second high-elastic cotton layer is arranged at the bend in the middle of the bent structure.

Preferably, the inner side of the second high-elastic cotton layer is provided with a first Velcro patch, the outer side of the first high-elastic cotton layer is provided with a second Velcro patch, the first Velcro patch and the second Velcro patch The shape and area of the sheets are the same as the second high-elastic cotton layer, and one of the first Velcro patch and the second Velcro patch is a positive sticker, and the other is a female sticker, so that the first Velcro patch and the second Velcro patch Can fit each other; the size of the solid gel layer is smaller than the size of the second high elastic cotton layer, and the second high elastic cotton layer can completely cover the solid gel layer.

The utility model provides a flexible interlayer knee protector or elbow protector composed of net-like air-permeable, cotton skin-friendly, high-elastic cotton layer and several layers of solid gel layer in the middle, which can prevent secondary knee joint or elbow joint pressure injury, To protect the skin, blood vessels, nerves, lymph, etc. around the knee joint or elbow joint, and avoid secondary injuries caused by "prone position ventilation". At the same time, it is equipped with different sizes of S, M, and L. You can choose the number of solid gel layers to add according to the fat and thin body shapes of different patients, differences in the bony protrusion of different knee joints or elbow joints, and different body positions and comfort levels. More comfortable wearing and better anti-pressure effect.

The utility model has a simple and effective structure and is easy to use, and there are two sets of knee joints or elbow joints respectively. It is washable and can be used multiple times; all cotton is skin-friendly and rarely causes skin allergic reactions, so it can be used by family members or patients when they are awake. It can also be used in hospitals and other medical institutions, such as patients with severe pneumonia in intensive care units, patients with chronic obstructive pulmonary emphysema in respiratory wards, geriatric wards, and patients with reduced lung function in nursing homes; it can also be used at home for chronic bronchitis with difficulty coughing up sputum, etc. Patients, the market application prospect is broad.

The device of the utility model is made of skin-friendly high-elastic cotton, and the cotton is breathable and not easy to be allergic; the anti-pressure part with prominent bone is more flexible to choose a combination pad of several layers of solid gel layer and high-elastic cotton layer, which can effectively relieve the pain. Bone prominence causes pressure on the surrounding skin, and several layers of solid gel layers in the middle interlayer replace the air-inflated decompression function of the existing air mattress, which has the pressure-relieving effect of the air cushion, but does not need the air leakage and inflation of the air cushion protector. Red tape. And it fits comfortably on the user's elbow or knee, which better relieves the pressure on the surrounding tissue of the compressed position;
