Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically an external fixation device for fractures of multiple ribs. Background Technology

[0002] In the medical and rehabilitation fields, rib fixation straps are used to support and protect injured ribs, reduce patient pain, and promote recovery. While rib fixation straps play an important role in treating rib fractures or other chest injuries, current technology has significant shortcomings in several key aspects. Specifically, existing rib fixation straps employ a single-sided fixation structure, meaning one end of the strap has hook-and-loop fasteners, and the other end has loop fasteners, achieving fixation through adhesion. This design makes it difficult to accurately control the tightness of the strap during wear, leading to inconsistent fixation. Insufficient tightness may result in poor support, while excessive tightness may affect patient comfort and blood circulation.

[0003] Furthermore, current rib fixation straps lack reinforcing strips, relying solely on the material properties of the strap itself for support and fixation in the width direction. This limits their ability to provide stable support, especially for recovery situations requiring high stability; existing designs cannot provide sufficient support, impacting recovery outcomes.

[0004] Meanwhile, due to structural design limitations, existing rib fixation straps are not convenient to wear. Wearing and adjusting the straps may require external assistance, causing inconvenience to patients and caregivers, especially for patients with limited mobility or one-handed operation ability, as this design reduces their independence. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this disclosure is to provide an external fixation device for fractures of multiple ribs.

[0006] The objective of this disclosure can be achieved through the following technical solutions:

[0007] An external fixation device for fractures of multiple ribs includes a base band, with multiple loops fixedly connected to the side ends of the base band;

[0008] A restraint strap passes through multiple loops and fits tightly against the side of a base strap. A connecting block is fixedly installed at one end of the restraint strap, and a snap-fit ​​block is fixedly connected to the front end of the connecting block. Insertion holes are provided on both sides of the snap-fit ​​block. Multiple through holes are evenly distributed on the side of the other end of the restraint strap. A movable block is installed at each through hole. A first through groove is provided on the front end face of the movable block to facilitate the passage of the restraint strap. A first circular hole is provided on the upper end of the movable block directly above the first through groove. The diameter of the first circular hole is equal to the diameter of the through hole. A first insertion component is fixedly connected to the first circular hole. A second through groove is provided on the upper end of the movable block to facilitate the insertion of the snap-fit ​​block. A second circular hole is provided on both sides of the movable block at the second through groove. The diameter of the second circular hole is equal to the diameter of the insertion hole. A second insertion component is fixedly connected to the second circular hole.

[0009] Furthermore, two shoulder straps are fixedly connected to the upper end of the baseband. A hook and loop fastener is fixedly connected to the back of the shoulder strap at the end away from the baseband. A loop fastener is fixedly connected to the front end of the baseband at the position corresponding to the shoulder strap. The hook and loop fasteners are adapted to each other.

[0010] Furthermore, a connecting strap is fixedly connected to one end of the baseband, and a buckle is fixedly connected to the back of the connecting strap.

[0011] Furthermore, a plurality of locking blocks are fixedly connected to the front side of the baseband away from the connecting strip, and each locking block has a locking groove on its front end face, the locking groove being adapted to a buckle.

[0012] Furthermore, the first plug-in assembly includes a first connecting plate, a first connecting spring, and a first pin. The first connecting plate is fixedly connected to the upper end of the moving block by two first connecting springs. One end of the first pin is fixedly connected to the side end of the first connecting plate, and the end of the first pin away from the first connecting plate passes through the first circular hole.

[0013] Furthermore, the second plug-in assembly includes a second connecting plate, a second connecting spring, and a second pin. The second connecting plate is fixedly connected to the side end of the movable block by two second connecting springs. One end of the second pin is fixedly connected to the side end of the second connecting plate, and the end of the second pin away from the second connecting plate passes through the second circular hole.

[0014] Furthermore, the baseband, restraint band, and shoulder straps are all elastic bands.

[0015] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0016] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0017] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0018] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0019] The beneficial effects of this disclosure are:

[0020] 1. In this device, the tightness of the baseband is adjusted by the cooperation of the buckle and the slot on the baseband.

[0021] 2. This device uses the cooperation of the locking block and the moving block on the restraint strap, and then adjusts the tightness of the restraint strap by adjusting the position of the moving block on the base strap. This ensures sufficient support while avoiding discomfort and blood circulation problems caused by excessive tightness. Attached Figure Description
