Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a wearable external thoracic fixation device. Background Technology

[0002] Multiple rib fractures refer to two or more fractures in each of two or more adjacent ribs. This can lead to local chest wall softening and paradoxical movement during breathing, which can easily cause mediastinal shift and thus affect the patient's respiratory and circulatory functions. This type of chest wall injury is also known as flail chest, a fatal chest injury that can endanger the patient's life if not treated promptly or properly. During the treatment process, chest wall fixation can relieve the patient's pain and eliminate paradoxical breathing, which is the key to the treatment of multiple rib fractures.

[0003] Currently, treatment methods for patients with multiple rib fractures and respiratory failure are generally divided into internal fixation and external fixation. Clinically, endotracheal intubation and positive pressure ventilation are often required to "internally fix" the floating chest. However, ventilator therapy is difficult to achieve under outpatient conditions, and even if it is achieved, it can only be a short-term transition. If it is desired to wean off the ventilator as soon as possible, internal fixation of the rib fractures is required through surgery. The internal fixation materials are mostly rib plates, Judet splints, Kirschner wires, or steel wires. The surgery is complex, invasive, and requires a sterile surgical environment, making it difficult to perform under outpatient conditions.

[0004] For external fixation of the thoracic wall, the most commonly used method in clinical practice is the rib plate. After being shaped, the rib plate is attached to the surface of the chest wall skin with adhesive tape. It is quite effective in preventing the floating chest wall from bulging outward. However, its effect on preventing the floating chest wall from sinking inward is limited. Furthermore, if the skin surface is heavily contaminated or there is a wound, the rib plate cannot be attached.

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

[0006] The purpose of this invention is to provide a wearable external thoracic fixation device, which has the advantage of limiting the inward and outward bulging of the chest wall, thereby improving the treatment capacity and efficiency for patients with multiple rib fractures.

[0007] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0008] A wearable external thoracic fixation device includes a chest strap worn on the patient's chest, with protective plates on both sides of the chest strap for limiting outward bulging of the chest wall and a grabbing ring mechanism at one end inserted into the thoracic cavity surface of the ribs for grabbing floating ribs and suspending them to limit inward cavitation of the chest wall.

[0009] Through the above technical solutions, the chest strap is easy to wear and can be tightly bound to the chest, which can initially limit the outward protrusion of the floating chest wall. However, since the chest strap is made of soft cloth material, it has a certain degree of elasticity and its restriction effect on the floating chest wall is insufficient. The protective plate set on the chest strap is made of malleable metal material. The protective plate supports the outside of the chest wall and further limits the outward protrusion of the chest wall. The grabbing ring mechanism is used to grab the fractured and floating ribs and lift them up. By traction of the ribs, the inward collapse of the floating chest wall is limited, which can improve the treatment capacity and efficiency for patients with multiple rib fractures.

[0010] In one embodiment of the present invention, the chest strap includes a connecting strap, a strip strap, and two end straps that are detachably connected to each other. Two or more strip straps are fixedly connected to both sides of the connecting strap. The two end straps are respectively fixedly connected to the strip straps located on both sides of the connecting strap. A first installation gap is provided between two adjacent strip straps.

[0011] Through the above technical solution, the chest strap can effectively tighten the patient's chest wall, playing a role in initially fixing the floating chest wall; the two end straps are detachable and easy to wear; the first installation gap allows the grabbing ring mechanism that grabs the floating ribs to pass through the chest strap and be pulled to the outer side of the guard plate, playing a role in traction of the floating ribs.

[0012] In one embodiment of this utility model, adhesive tapes corresponding to the strip strips are provided on both sides of the connecting strip, and the adhesive tapes are detachably connected to the strip strips.

[0013] The above technical solution uses adhesive tape and strip tape together to fix the guard plate and the grab ring mechanism.

[0014] In one embodiment of this utility model, both the strip and the adhesive tape are elastic bands.

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

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

[0017] The above technical solution uses shoulder straps to reinforce the wearing of the chest strap and prevent it 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 protective plates are detachably fixed on the strip, and a second installation gap is provided between two adjacent protective plates. The grab ring is inserted into the rib chest cavity 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 and the two long sides are laid on the protective plate.

[0020] With the above technical solution, the two wide sides of the clamping plate are located on the strip, the two long sides of the clamping plate are laid on the guard plate, the clamping plate is fixed between the guard plate and the adhesive strip, and the grab ring is fixed to the clamping plate by the traction belt, thereby enabling the grab ring to pull the rib.

[0021] In one embodiment of the present invention, the gripping ring includes two mutually hinged jaws and a latch disposed on the jaws for limiting the opening of the two jaws.

[0022] In one embodiment of the present invention, the latch includes a support plate fixed on a gripper, a locking plate hinged to the support plate, a locking block fixed on the locking plate, and a slot disposed on another gripper and engaged and fixed with the locking block.

[0023] The above technical solution uses a locking buckle to lock the two grippers, thereby facilitating the gripping ring to firmly grasp and pull the ribs.

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

[0025] The above technical solution 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, the soft dressing layer being located near the strip.

[0027] Through the above technical solution, the shaping layer has a certain supporting strength, and the soft dressing layer contacts the patient's chest wall to avoid causing secondary damage to the wound.

[0028] As described above, the wearable external thoracic fixation device of this utility model has the following beneficial effects:

[0029] The chest strap is conveniently worn on the patient's chest, providing initial fixation of the rib cage and initially limiting the outward protrusion of the floating chest wall. The malleable protective plate further limits the outward protrusion of the chest wall, while the grab rings pull the ribs to limit the inward collapse of the chest wall. This improves the treatment capacity and efficiency for patients with multiple rib fractures. Attached Figure Description

[0039] Please see Figure 1 and Figure 2This utility model provides a wearable external thoracic fixation device, including a chest strap 1 worn on the patient's chest. Both sides of the chest strap 1 are provided with protective plates 2 for limiting the outward protrusion of the chest wall and a grabbing ring mechanism 3 with one end inserted into the thoracic cavity surface of the rib and used to grab the floating rib and suspend it to limit the inward collapse of the chest wall.

[0040] Please see Figure 1 , Figure 2 and Figure 3 The chest strap 1 includes a connecting strap 11, two or more strips 12 fixedly connected to both sides of the connecting strap 11, and two detachably connected end straps 13. The connecting strap 11 is a single piece of soft fabric. In this embodiment, five strips 12 and five adhesive tapes 14, each corresponding to one of the strips 12, are sewn and fixed to opposite sides of the connecting strap 11. Velcro fasteners are provided on the opposite sides of the adhesive tapes 14 and the strips 12, allowing the strips 12 and adhesive tapes 14 to be adhesively connected. The strips 12 and adhesive tapes 14 are elastic bands, which have good extensibility, thus allowing the chest strap 1 to fit various body types. For use by people of the same body type; a first installation gap is provided between two adjacent strips 12; two end straps 13 are sewn and fixed to the ends of the strips 12 located on both sides of the connecting strap 11; each end strap 13 is provided with Velcro, so that the two end straps 13 can be connected by adhesive, and the ends of the adhesive tapes 14 on both sides are also attached to the end straps 13 by Velcro, thereby strengthening the adhesion between the adhesive tapes 14 and the strips 12; two shoulder straps 15 are sewn and fixed to the connecting strap 11, wherein the shoulder straps 15 are also elastic bands, and the other end of each shoulder strap 15 is provided with Velcro, so that both shoulder straps 15 are connected to the end straps 13 by adhesive.

[0041] Please see Figure 4 , Figure 5 and Figure 6 The grab ring mechanism 3 includes a clamping plate 31, a traction belt 32 fixedly connected to the clamping plate 31, and a grab ring 33 fixedly connected to the other end of the traction belt 32; wherein the clamping plate 31 near the traction belt 32 is provided with Velcro.

[0042] At least two protective plates 2 are detachably fixed to the strip 12, and both protective plates 2 are set approximately perpendicular to the strip 12. The protective plate 2 includes a shaping layer 21 and a soft dressing layer 22 fixed below the shaping layer 21, with the soft dressing layer 22 on the side closer to the strip 12. The shaping layer 21 is a malleable metal material, such as aluminum sheet or copper sheet. Velcro is provided on both the upper and lower sides of the protective plate 2, so that the soft dressing layer 22 of the protective plate 2 can be pasted and fixed to the strip 12. The clamping plate 31 is pasted and connected to the outer side of the shaping layer 21 of the protective plate 2. A second installation gap is provided between two adjacent protective plates 2. The grab ring 33 is inserted into the rib chest cavity surface. The clamping plate 31 and the traction belt 32 pass through the first installation gap and the second installation gap. The two wide sides of the clamping plate 31 are located on the strip 12, and the two long sides overlap the protective plate 2.

[0043] Then, the adhesive tape 14 is attached to the strip 12, further fixing the card plate 31 and the guard plate 2 between the strip 12 and the adhesive tape 14.

[0044] Please see Figure 4 and Figure 5 The gripper ring 33 includes two hinged grippers 331 and a latch 34 disposed on the grippers 331 and used to limit the opening of the two grippers 331. The grippers 331 have a C-shaped structure and the tips of the grippers 331 are set as triangular pins.

[0045] The latch 34 includes a support plate 341 integrally formed on the upper end of the left gripper 331, a locking plate 342 hinged to the support plate 341, a locking block 343 integrally formed on the locking plate 342, and a slot 344 disposed on the upper end of the right gripper 331 and engaged and fixed with the locking block 343; a protruding plate 345 integrally formed on the end of the support plate 341 near the locking block 343; and one end of the traction belt 32 is fixedly disposed in the middle of the locking plate 342.

[0046] Brief description of usage: When using, open the gripper ring 33, insert one claw 331 from the lower edge of the rib to the thoracic surface of the floating rib, and then insert the other claw 331 along the upper edge of the rib to the thoracic surface of the rib. Take care to protect the intercostal nerves and blood vessels. Then fasten the buckle 34 at the top of the gripper ring 33 to fix the gripper ring 33. At this time, the clamping plate 31 and the traction strap 32 remain outside the chest cavity.

[0047] The connecting strap 11 is located on the back of the injured person, the two side strips 12 are located on the sides of the chest, and the end straps 13 are located on the front of the chest. After wrapping the chest strap 1 around the patient's chest, the two end straps 13 are glued together. Then, the two shoulder straps 15 are wrapped around the shoulders and glued to the end straps 13. (Note that before the two end straps 13 are glued together, the clamping plate 31 and the traction strap 32 connected to the grab ring 33 that has been inserted into the chest wall should be passed out through the first installation gap.)

[0048] Then take two guard plates 2, which are approximately perpendicular to the strip 12 and located on both sides of the traction belt 32 and pasted onto the strip 12; then place the two long sides of the clamping plate 31 on the guard plates 2; then cover the guard plates 2 and clamping plates 31 with the adhesive tape 14 and paste it onto the strip 12 one by one to further fix the clamping plates 31 and guard plates 2.

[0049] The position of the grab ring 33 and the guard plate 2 on the strip 12 can be adjusted to traction the ribs floating in different positions.

[0050] In summary, this invention restricts the outward protrusion of the floating chest wall by using the malleable protective plate 2, and restricts the inward collapse of the floating chest wall by using the grabbing ring mechanism 3 to pull the ribs. The chest strap 1 wrapped around the chest not only assists in fixing the floating chest wall, but also further fixes the malleable protective plate 2 and the grabbing ring mechanism 3, thus achieving a firm fixation of the floating chest wall. This improves the treatment capacity and efficiency for patients with multiple rib fractures. At the same time, it solves the problem that external fixation materials that can be pasted onto the chest wall skin cannot be used when there are wounds on the chest wall skin.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
