Description

Technical Field

[0001] This utility model relates to the technical field of arm support and restraint devices, specifically an arm support and restraint device with an inflatable limiting structure. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses drugs, surgery and physical methods to maintain and develop the normal morphology and function of this system.

[0003] Among them, the "Automobile Seat and Spinal Support Restraint Device for Automobile Seat" disclosed in application number "CN117124958A" is also an increasingly mature technology. "The spinal support restraint device is configured to restrain at least one shoulder of an occupant (1) sitting in the automobile seat. The spinal support restraint device includes at least one restraint strap assembly (13) connected to the seat back. The restraint strap assembly includes a flexible strap material and forms an annular restraint strap loop. The restraint strap loop is configured to pass through the armpit of a corresponding shoulder of the occupant and restrain the corresponding shoulder when the occupant is sitting in a reclining position in the automobile seat. In particular, when the angle of the seat back (11) is adjusted to the working and leisure sitting positions of the occupant in the automobile seat (10), especially in frontal collision events, the spinal support restraint device can improve the motion posture of the occupant (1), relieve the spinal pressure of the occupant, and improve the safety of the occupant."

[0004] The "Arm Tray Device for CT-Guided Interventional Diagnosis and Treatment" disclosed in application number "CN109091162B" is also an increasingly mature technology. It includes a head support base and a hand support assembly. The head support base includes an upper body and a lower body. The upper body is configured to move closer to the lower body under pressure. The upper body has a head support groove and a pressing element. The lower body has a slot. When the upper body moves closer to the lower body, the pressing element is inserted into the slot. The hand support assembly is located on both sides of the head support base and connected to it. The hand support assembly gradually tilts upward from the side closer to the head support base to the side farther away from the head support base. The hand support assembly has an arm support groove and a restraint element for restraining the arm within the arm support groove. The effects are: firstly, it can support and restrain the arm, improving comfort and preventing arm movement from affecting examination results; secondly, it can elevate and restrain the hand, preventing the infusion needle on the back of the hand from touching foreign objects.

[0005] However, the above-mentioned arm tray device has the following disadvantages: the arm tray device supports the arm by combining the lower seat, upper seat, hand support component and support groove. This structural design is relatively simple and can only fix the arm. Moreover, the fixing structure cannot be adjusted, which has certain drawbacks for fixing arms of different thicknesses. During the fixing process, it is easy to become unstable or unable to fix a thick arm.

[0006] Therefore, it is necessary to provide an arm support restraint device with an inflatable limiting structure to solve the above problems. Utility Model Content

[0014] Preferably, the locking mechanism includes lead screws that are inserted and connected to both sides of one end of the locking frame, a fixing ring that is threaded through one end of the lead screws, a fixing ring that is provided in the middle of the locking frame, and an airbag retainer that is inserted and connected to the side of the fixing ring by a limiting screw.

[0015] By adopting the above technical solution, the fixed ring can be adjusted by threaded insertion between the fixed ring and the lead screw, and the fixed ring can be adjusted and moved to a limited position. At the same time, the arm is clamped and fixed by the airbag retainer that is aligned with the fixed ring.

[0035] like Figures 1-6 As shown, the present invention proposes an arm support restraint device with an inflatable limiting structure, including an arm fixing bracket 1, an inflatable limiting mechanism 2 provided on the top of the arm fixing bracket 1, a fixing mechanism 3 movably connected to one end of the arm fixing bracket 1, an adjusting mechanism 4 provided at the other end of the arm fixing bracket 1, a locking mechanism 5 movably connected to one side of the adjusting mechanism 4, and a data processing mechanism 6 fixedly connected to one side of the arm fixing bracket 1.

[0036] The inflatable limiting mechanism 2 includes an inflatable fixing frame 201 fixedly connected to the top of the arm fixing bracket 1. Several sets of through slots 202 are opened on both sides of the inflatable fixing frame 201. A first limiting airbag ring 203 is inserted between each set of through slots 202. A device frame 204 is fixedly connected to the middle of the inflatable fixing frame 201. A small screw 205 is threadedly connected to the top of the device frame 204. A turntable 206 is fixedly connected to the top of the small screw 205. A second inflatable pressing airbag 209 is fixedly connected to the bottom of the small screw 205. A first electric telescopic rod 208 is fixedly connected to both sides and the bottom of the device frame 204. A third inflatable pressing airbag 209 is fixedly connected to the telescopic end of the first electric telescopic rod 208.

[0037] In practical use, when supporting and restraining the patient's arm, in order to ensure that the arm can be properly fixed and prevent arm movement, several sets of through slots 202 on the inflatable fixing frame 201 facilitate the installation and fixing of the first limiting airbag ring 203. This allows the first limiting airbag ring 203 to further limit and fix the arm when inflated. The several sets of first limiting airbag rings 203 facilitate the complete fixation of the arm. The small screw 205 on the device frame 204 can be manually rotated to rotate the turntable 206, making it easier for the small screw 205 to rotate closer to the arm. The second inflatable compression airbag 209 is inflated to fix the arm. The extension and retraction of several first electric telescopic rods 208 facilitate the pushing of the third inflatable compression airbag 209 to fit against the arm, thereby providing support and limiting fixation.

[0038] The fixing mechanism 3 includes a fixing frame 301 that is movably connected to one end of the arm fixing bracket 1 via a movable screw. A small motor 302 is fixedly connected to one side of the fixing frame 301. A connecting frame 303 is movably connected to the transmission end of the small motor 302.

An air pump 307 is fixedly connected to one end of the air supply tube 306.

[0039] In practical use, when the arm is fixedly installed and supported on the fixed frame 301, in order to better support and fix the arm, the rotation of the small motor 302 drives the connecting frame 303 to rotate, so that the angle of the connecting frame 303 can be adjusted, thereby facilitating the adjustment of one of the airbag ring tubes 304, which is convenient for limiting and fixing the arm. The two sets of airbag ring tubes 304 are provided to facilitate the limiting and fixing of the arm and prevent movement. In order to facilitate the fixing of the airbag ring tubes 304 to the arm, the locking lock 305 and the buckle are provided to facilitate the fixing of the airbag ring tubes 304 to the arm and facilitate the limiting use.

A fixing ring 502 is threadedly connected to one end of the lead screw 501. A fixing ring 503 is provided in the middle of the locking frame 404. An airbag housing 504 is inserted and connected to the side of the fixing ring 503 through a limit screw.

[0043] In practical use, when the arm is clamped and limited, the fixed ring 502 and the lead screw 501 are threaded and adjusted to allow the fixed ring 502 to move and limit the movement. At the same time, the fixed ring 503 is clamped and fixed to the airbag housing 504.

[0044] The data processing mechanism 6 includes a mounting plate 601. A wireless receiving module 602 is fixedly connected to the top of the mounting plate 601.
