Description

A multifunctional anti-dislocation device after hip replacement surgery

Technical field

The utility model relates to the technical field of medical appliances, specifically a multifunctional anti-dislocation device after hip replacement surgery.

Background technique

Artificial hip replacement has been widely carried out clinically, even in most primary hospitals in my country. There are many surgical approaches for hip replacement surgery, among which the posterolateral approach is the most common. This approach can well avoid the nerve and blood vessel interface, easily reach the surgical area, and has good ductility, sufficient exposure, and can Complete surgical treatment of various hip joint diseases. However, this surgery has another disadvantage: it requires cutting off the hip external rotator muscles, and there is a risk of dislocation of the hip prosthesis after surgery, especially for elderly patients with poor muscle strength, poor mobility, and patients with other underlying diseases. wait.

In order to avoid dislocation after hip replacement, the patient's affected limb needs to be abducted to a neutral position to prevent dislocation after hip replacement. In clinical practice, after hip replacement surgery, in order to keep the patient's affected limb abducted to a neutral position, pillows, patient's clothing, etc. are often placed between the patient's lower limbs. However, care often occurs due to negligence or the patient's inability to cooperate due to Alzheimer's disease. Dislocation occurs, and it is also inconvenient to care for. There is a hip abduction brace in the prior art. Placing the brace between the patient's legs can prevent hip joint dislocation. However, the brace has a high cost, a complex structure and a hard material, which results in poor patient comfort.

Compared with the existing technology, the beneficial effects of this utility model are:

1. This utility model is a multifunctional anti-dislocation device after hip replacement surgery. When used, the inflatable bag only needs to be fixed to the thigh of the affected limb to achieve the effect. The unaffected limb does not need to be fixed at the same time, and the movement is not restricted. Buttons and zippers are designed to adapt to patients of different body types. When the distance between the patient's legs is large, the zipper will be opened, otherwise the zipper will be closed. When the patient's legs are short, the snap button will be fastened, and if the distance between the patient's legs is short, the snap button will be opened.

2. When accidents such as the strap falling off or the patient deliberately moving the affected limb cause the magic band to separate from the inflatable bag, the alarm device will sound to remind medical staff to check the patient, further reducing the patient's risk of hip dislocation. The pressure sensor detects the pressure of the movable part in real time and sends the pressure signal to the processor. When the pressure signal received by the processor exceeds the set threshold, the alarm is controlled to alert the medical staff to help the patient turn over, further reducing the risk of the patient developing pressure ulcers. .

3. The device of this utility model is simple and effective in design, widely used, low in cost, and good for patient comfort. The utility model has the advantages of simple structure, reasonable setting, and low production cost.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, the utility model is a multifunctional anti-dislocation device after hip replacement surgery, including an inflatable bag 3, an inflatable hole 5, a tear-away magic band 4, a snap button and a zipper 2; the inflatable The bag 3 is in the shape of a block, and the cross-sectional shape of the inflatable bag 3 is trapezoidal. The contact surfaces between the two sides of the inflatable bag 3 and the affected limb are curved surfaces. There are multiple tear-away magic bands 4 on both sides of the front and back of the inflatable bag 3. The inflatable bag 3 is provided with multiple pairs of snap buttons on both sides and sides of the front, two rows of zippers 2 are provided in the middle of the inflatable bag 3, and an inflatable hole 5 is provided on one side of the inflatable bag 3.
