Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a wearable thorax external fixation device. Background Art

[0002] Multiple rib fractures refer to two or more fractures in two or more adjacent ribs, which can lead to local softening of the chest wall and abnormal movement with breathing, easily causing mediastinal flutter, and thus affecting the respiratory and circulatory functions of the injured person. This chest wall injury is also called flail chest, which is a fatal chest injury. If not treated in time or improperly, it can endanger the life of the injured person. During the treatment process, chest fixation can relieve the pain of the injured person and eliminate abnormal breathing, which is the key to the treatment of multiple rib fractures.

[0003] At present, the treatment methods for patients with multiple rib fractures and respiratory insufficiency are roughly divided into internal fixation and external fixation. Clinically, endotracheal intubation and positive pressure ventilation of the ventilator are often required to "internal fixate" the floating thorax. However, ventilator treatment is difficult to achieve under out-of-hospital treatment conditions, and even if it is achieved, it can only be a short-term transition. If you want to get off the ventilator as soon as possible, you need to undergo surgery to internally fix the rib fractures. The internal fixation materials are mostly rib plates, Judet splints, Kirschner wires or steel wires, etc. The operation is complicated, the trauma is large, and a sterile operating environment is required, which is difficult to perform under out-of-hospital treatment conditions.

[0004] For external fixation of the thorax, the rib plate is currently commonly used in clinical practice. After being shaped, the rib plate is adhered to the skin surface of the chest wall as a whole through adhesive tape. It is relatively effective in preventing the floating chest wall from bulging outward; however, its effect on preventing the floating chest wall from sinking inward is limited; and if the skin surface is heavily contaminated or there is a wound, the rib plate cannot be adhered.

[0005] Currently, there is no external chest fixation device that can effectively traction the floating chest wall of patients with multiple rib fractures under out-of-hospital treatment conditions. Summary of the invention

[0006] The purpose of the present invention is to provide a wearable thoracic external fixation device, which has the advantage of being able to limit the inward and outward bulges of the chest wall and improve the ability and efficiency of treating patients with multiple rib fractures.

[0007] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0008] A wearable chest external fixation device comprises a chest strap worn on the patient's chest, wherein both sides of the chest strap are provided with a guard plate for limiting the outward convexity of the chest wall and a grabbing ring mechanism with one end inserted into the chest surface of the ribs and used to grab the floating ribs and lift them to limit the inward depression of the chest wall.

[0009] Through the above technical scheme, the chest strap is easy to wear and can be tightly tied around the chest, which can preliminarily limit the bulging of the floating chest wall; since the chest strap is made of soft cloth material and has a certain degree of extensibility, the limiting effect on the floating chest wall is insufficient, and the guard plate arranged on the chest strap is a plastic metal material, and the guard plate is supported on the outside of the chest wall, which further limits the bulging of the chest wall; the grab ring mechanism is used to grab fractured and floating ribs and lift them up, and by pulling the ribs, the inward collapse of the floating chest wall is limited, which can improve the treatment ability and efficiency of patients with multiple rib fractures.

[0015] Through the above technical solution, the elastic band has good extensibility and can be adapted to patients of different body shapes.

[0016] In one embodiment of the present invention, two shoulder straps are fixed to the connecting belt, and the other ends of the shoulder straps are detachably connected to the end straps.

[0017] Through the above technical solution, the shoulder straps are used to reinforce the wearing of the chest strap to prevent the chest strap from falling off.

[0018] In one embodiment of the present invention, the grab ring mechanism includes a clamping plate, a traction belt fixedly connected to the clamping plate, and a grab ring fixedly connected to the other end of the traction belt;

[0019] At least two guard plates are detachably fixed on the strip belt, a second installation gap is arranged between two adjacent guard plates, the grab ring is inserted into the rib thoracic surface, the clamping plate and the traction belt pass through the first installation gap and the second installation gap, the two wide sides of the clamping plate are located on the strip belt, and the two long sides are placed on the guard plates.

[0020] Through the above technical scheme, the two wide sides of the pallet are located on the strip belt, the two long sides of the pallet are placed on the guard plate, the pallet is fixed between the guard plate and the adhesive belt, the grab ring is fixed to the pallet through the traction belt, and then the grab ring pulls the ribs.

[0021] In one embodiment of the present invention, the gripping ring includes two clamping jaws hinged to each other and a lock buckle disposed on the clamping jaws and used to limit the opening of the two clamping jaws.

[0022] In one embodiment of the present invention, the lock includes a support plate fixed on one clamping jaw, a locking plate hinged to the support plate, a clamping block fixed to the locking plate, and a clamping slot arranged on the other clamping jaw and clamped and fixed to the clamping block.

[0023] Through the above technical solution, the lock buckle is used to lock the two clamping claws, so that the grab ring can firmly grasp and pull the ribs.

[0024] In one embodiment of the present invention, a convex plate is integrally formed at the end of the support plate.

[0025] Through the above technical solution, the convex plate facilitates the opening and locking of the locking plate.

[0026] In one embodiment of the present invention, the protective plate includes a shaping layer and a soft dressing layer fixed on the shaping layer, and the soft dressing layer is close to one side of the strip.

[0027] Through the above technical solution, the shaping layer has a certain supporting strength, and the soft dressing layer contacts the chest wall of the injured person to avoid secondary injury to the injured area.

[0028] As described above, the wearable thorax external fixation device of the present invention has the following beneficial effects:

[0029] The chest strap is conveniently worn on the patient's chest, which plays a role in the initial fixation of the thorax and can initially limit the bulge of the floating chest wall; the bulge of the chest wall is further limited by the moldable guard plate, and the chest wall retraction is limited by the traction of the ribs by the grab ring; the treatment capacity and efficiency of patients with multiple rib fractures are improved.
