Knee restraint strap

Abstract

The invention discloses a knee restraint strap which comprises a restraint strap body used for restraining the knees of a patient and fixing the knees to a sickbed, and the restraint strap body comprises a knee fixing component used for fixing the left knee joint and the right knee joint of the patient and a knee adjusting component arranged on the knee fixing component; the knee adjusting component is used for adjusting the knee joint girth of the patient so as to adapt to patients with different knee joint girths, patella holes are formed in the knee fixing component, the patellas of the patient are exposed outside through the patella holes, a patella hole adjusting structure is arranged on each patella hole, an adjusting and fixing assembly adjusts patients with patella holes of different sizes through the patella hole adjusting structures, the whole restraint strap better restrains the bodies of different patients through the patella hole adjusting structures, and more comfortable nursing is provided for the patients.

Description

technical field [0001] The invention relates to the technical field of medical care, in particular to a knee restraint belt for a patient. Background technique [0002] The patella is the largest sesamoid bone in the human body. It is located in front of the lower end of the femur and inside the quadriceps tendon. The function of the tendon to rub against the cartilage surface of the femoral condyle is to transmit the strength of the quadriceps femoris and participate in the function of the knee extension device; it can maintain the stability of the knee joint in a semi-squatting position and prevent excessive adduction, abduction, and extension and flexion of the knee joint function, as well as the function of the car chain to increase the rotation ability of the knee joint. [0003] The restraint belt is a kind that can control the occurrence of dangerous behaviors of patients (such as suicide, self-injury, extreme excitement, and obvious aggressive behavior), prevent pat...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing restraint belt cannot be adjusted according to the size of the patient's patella or the size of the knee joint, and is easy to slip off, and cannot adapt to patients of different body types. The adjustable restraint strap includes a left restraint strap and a right restraint strap, fixed straps are arranged at the left, front, rear, upper and lower sides of the left restraint strap, and a left adjustable fixed strap is arranged at the right end of the left restraint strap device, the left adjustment fixing belt device includes a left adjustment fixing hole, a left fixing tie belt and a left post type zipper, and the tie belt is changed into an expansion tie belt device, a left adjustment fixing belt device and a right adjustment fixing belt device, although The dismantling and installation work can be carried out by expanding the restraint belt device, the left adjustment fixing belt device and the right adjustment fixing belt device, but there are also some deficiencies in Document 1: the left adjustment fixing hole and the right adjustment fixing hole are fixed, yes It cannot be adjusted, so the restraint belt cannot be adapted to the body shapes of different patients. For example, adults and children have different patella sizes. Using the restraint belt that restrains adults to restrain children, the fixation effect of the restraint belt is not good;

[0006] (2) The existing restraint belt is relatively fixed through the connection between the knee joint and the bed, which will fix the knee joint too tightly, which will not only affect the comfort, but also cause poor blood circulation, affect the postoperative recovery of the patient, prolong the recovery time, and reduce the satisfaction of the patient Spend;

[0007] (3) After the existing restraint belt restrains, the left and right knee joints will be firmly fixed, which will affect the range of motion of the joints on the one hand, and will hinder the medical care operation on the other hand, causing great harm to the clinical work. Inconvenient, for example, Chinese document 2 (CN111658282A) discloses a knee joint restraint belt, including a cloth body, the left side of the cloth body is fixedly provided with a left leg fixing belt, and the right side of the cloth body is fixedly provided with a right leg fixing belt. belt, the left leg fixing belt and the right leg fixing belt are symmetrically arranged relative to the cloth body, and the cloth body is provided with a left leg fixing belt hole and a right leg fixing belt hole, and the left leg fixing belt The hole is set close to the left leg fixing belt, and the right leg fixing belt hole is set close to the right leg fixing belt. Although the restraint belt in Document 2 can restrain the knee joint of the patient, this restraint belt also exists Some disadvantages are that the left and right knee joints are fixed and cannot be adjusted, which is inconvenient for medical staff to operate and not conducive to postoperative recovery of patients.

[0008] Therefore, the existing restraint belts are prone to slipping, poor fixation effect, affecting postoperative recovery of patients, unable to perform restraint care for different patients, unable to adapt to the needs of different patients, unable to provide patients with comfortable and personalized care, and at the same time To a certain extent, issues such as affecting the development of medical care work
