Referring to fig. 1-2, the hip joint restraint device in the embodiment of the present invention includes a support frame 1, an air cushion 2, a fixing band 3 and a restraining band 4. The support frame 1 is a support member of the whole device, and has the functions of supporting other parts and limiting the bending of the knee joint of a patient. Specifically, the support frame 1 is U-shaped, the shape of the outer side of the support frame is not required, but the inner side of the support frame needs to be attached to the knee joint of the patient, and the accommodating space 11 of the inner side of the support frame is designed to be smooth and arc-shaped, so that the discomfort brought to the patient when the support frame is fixed on the knee joint of the patient is reduced.

The air cushion 2 is disposed in the accommodating space 11 and connected with the inner wall of the accommodating space 11. Specifically, the two are fixed to each other by means of adhesion or clamping, and other connection means capable of achieving the same connection effect may be used. The air cushion 2 is made of elastic materials, an air cavity is arranged in the air cushion, and the air cavity is communicated with an air inlet on the air cushion 2, so that an external inflating device can be used for inflating the air cavity, the air cushion 2 is made to expand, and the fitting degree of the air cushion 2 and the knee joint of a patient is adjusted. By changing the volume of the gas in the gas cavity, the hip joint restraint device can be adapted to patients with different body types, the applicability of the hip joint restraint device is improved, and the use feeling of the patients is also improved.

When the hip joint restraint device is not suitable for use, the air in the air cushion 2 can be discharged, so that the volume of the hip joint restraint device is reduced, and the hip joint restraint device is convenient to store.

It is easy to understand that the air cushion 2 can be replaced by other cushion layers, so as to avoid the rigid support frame 1 from being in direct contact with the skin of the patient to scratch, and influence the use feeling of the patient.

The fixing strap 3 is connected on the support frame 1, bypasses the knee joint of the patient and fixes the support frame 1 and the knee joint of the patient together, so as to prevent the hip joint restraint device from falling off from the knee joint of the patient. Specifically, the number of the fixing bands 3 can be increased or decreased according to actual conditions, and preferably, in order to achieve the effect of stable fixation, the number of the fixing bands 3 is at least two, and the fixing bands are respectively wound around the upper side and the lower side of the knee joint of the patient and fixed.

The restraint strap 4 is connected on the support frame 1, bypasses the edge of the sickbed and is fixed with bed body fixing structures such as a bed frame, and the knee joint of a patient can be fixed with the sickbed through the hip joint restraint device. Therefore, the knee joint can not be bent or displaced, and the hip joint of the patient can not move due to the linkage of the human body structure, so that the effect of restraining the hip joint is achieved. Specifically, the number of the restraint straps 4 can be increased or decreased according to actual conditions, so that the restraint failure caused by the fact that the patient with large strength breaks loose from restraint is prevented. Preferably, the number of the restraining strips 4 is at least two in order to exert a stable restraining effect.

Compared with the traditional hip joint restraint device, the hip joint restraint device can avoid the restraint device from interfering X-ray detection or treating the hip joint. The bending of the knee joint of the patient is limited by using the support frame 1, the displacement of the knee joint of the patient is limited by the restraint strap 4, and the bending of the hip joint is indirectly limited by the structural linkage of the human body. Moreover, the hip joint restraint device has smaller volume, is easy to carry, disassemble and assemble and is convenient to be widely used.

The metal strip 12 is used for limiting the bending of the knee joint of the patient, and simultaneously can reduce the weight of the support frame 1, reduce the weight of the hip joint restraint device and improve the comfort of the patient when the patient wears the hip joint restraint device. Specifically, in order to make the force applied to each metal strip 12 uniform, each metal strip 12 is arranged at an equal distance in the front-rear direction. The metal strap 12 is made of iron or stainless steel, or other metal material, to limit the flexion of the patient's knee.

In other embodiments, the metal strip 12 may be replaced by a carbon fiber strip, and the shape and the connection manner of the carbon fiber strip are the same as those of the metal strip 12, so that the description thereof is omitted here. The carbon fiber strips have good rigidity and strength, and can well limit the knee joint of a patient. And because the carbon fiber strips are made of non-metallic materials, the interference of the hip joint restraint device on X-rays can be reduced when the X-rays are detected. It will be readily appreciated that other non-metallic materials having the same constraining effect may be used and will not be described in detail herein.

Further, support frame 1 still includes a plurality of adhesive tapes 13, and adhesive tape 13 has elasticity, and adhesive tape 13 sets up along the fore-and-aft direction. The number of the rubber strips 13 can be increased or decreased according to the practice situation, and each rubber strip 13 is connected with all the metal strips 12, so that the metal strips 12 are connected into a whole, and the distance between the metal strips 12 can be limited. When the patient's knee is flexed, the rubber strip 13 will flex slightly to cushion the impact of the knee flexion on the present hip restraint. However, due to the rigidity limitation of the individual metal strips 12, the knee joint is limited from further bending. Thereby not only protecting the knee joint of the patient to a certain extent, but also limiting the bending of the knee joint.

Further, the end portions of the fixing band 3 and the restraining band 4 are both provided with a quick-release structure, and the quick-release structure can conveniently and quickly fix the fixing band 3 or the restraining band 4 through the quick-release structure. Specifically, in some embodiments, the quick release structure includes a male plug and a female plug, a fastening space is provided in the female plug, and the male plug is inserted into the fastening space and then is fastened into the notches at two sides of the fastening space due to its deformation, thereby forming a locking effect. When the unlocking is needed, the clamping bulges on the two sides of the male head of the plug-in buckle are respectively clamped by a thumb and a forefinger, and the plug-in buckle can be unlocked by pressing the plug-in buckle into the buckle space. The locking and unlocking are both convenient, the locking is firm, and the lock is not easy to break loose forcibly. Specifically, the male plug is arranged at one end of the fixing band 3 or the restraint band 4, and the female plug is arranged on the support frame 1, or the male plug and the female plug are arranged in a mutually reversed manner, which is not described in detail herein.
