Description

Technical Field

[0001] This utility model relates to a fixation device, and more particularly to a rib fracture fixation device. Background Technology

[0002] A rib fracture is a break or crack in the ribs, usually caused by external impact or pressure. Common symptoms include severe pain, difficulty breathing, and pain when coughing. In some severe cases, surgical intervention may be required, such as surgical fixation of the fracture site. Some patients with severe fractures lie in bed after surgery, and the top of their chest cavity cannot bear weight, so they cannot be covered with a blanket for warmth. If the top of the chest cavity is not covered with a blanket, it may lead to insufficient warmth in this area, increasing the risk of infection and potentially delaying healing. Fixation devices are needed to prevent blankets or other objects from compressing the patient's chest cavity.

[0003] For example, Chinese Patent Publication No. CN221286045U discloses a fixation device for rib fractures, which relates to the field of orthopedic medical device technology. It includes a base support box, a protective frame hinged to the side of the base support box, arc-shaped grooves on both sides of the protective frame, a fixing component at the bottom of the base support box for fixing the fixation device to a medical bed, symmetrical weight-reducing grooves at the top of the protective frame, a top connecting block fixedly located in the middle of the side of the protective frame, a bottom connecting block fixedly located at the bottom of the top connecting block on the side of the base support box, a connecting column fixedly located at the top edge of the bottom connecting block, and a limiting component fixedly located at the top of the connecting column for limiting the protective frame to the top of the base support box. The overall structure of this utility model includes a base support plate and a protective frame rotatably mounted on top of the base support plate. The patient can lie in the gap between the base support plate and the protective frame, protecting the chest cavity while a blanket can be placed on top of the protective frame to keep the patient warm.

[0004] The aforementioned fixation device for rib fractures has some problems. First, although the protective frame and base support can effectively protect the patient's chest cavity, the patient needs to lie inside the device. During the transfer of the patient with a rib fracture, the patient will experience more pain and may also be more prone to further damage to the fracture site. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a rib fracture fixation device, including an arc-shaped protective plate 1. The inner wall of the arc-shaped protective plate 1 is symmetrically provided with limiting grooves 2 near the lower edges on both sides. Limiting sliders 202 are slidably installed in the limiting grooves 2. A locking block 204 is fixedly connected to the limiting slider 202. A locking through hole 205 is opened in the locking block 204. An elastic strap 4 is provided below the arc-shaped protective plate 1. The two ends of the elastic strap 4 are fixedly connected with locking posts 401. The locking posts 401 cooperate with the locking through holes 205. Limiting rods 102 are fixedly connected to the lower edges on both sides of the elastic strap 4. Support feet 3 are slidably connected to the limiting rods 102.

[0022] In this implementation, the arc-shaped protective plate 1 is fastened above the patient's abdominal cavity, and the support leg 3 is in contact with the patient's lying bed, thus supporting the arc-shaped protective plate 1 in a suspended position. The limiting slide rod 102 is slidably connected to the support leg 3, allowing the support leg 3 to move up and down, adjusting the distance between the support leg 3 and the arc-shaped protective plate 1 so that the bottom of the arc-shaped protective plate 1 fits as close as possible to the patient's chest cavity. The elastic strap 4 is pressed under the patient's back. Then, the locking post 401 is placed between the two locking blocks 204 on one side. Moving the limiting slide rod 202 can drive the locking blocks 204 to move, reducing the size of the two locking blocks. The spacing between the connecting blocks 204 allows the locking pins 401 to be inserted into the locking holes 205, and then the two ends of the elastic straps 4 are connected to the arc-shaped protective plate 1. At this time, the patient uses their own weight to conduct it to the arc-shaped protective plate 1 through the elastic straps 4, applying a certain downward pressure to the arc-shaped protective plate 1, so that the arc-shaped protective plate 1 is fastened to the hospital bed, preventing the blanket from moving. The arc-shaped protective plate 1 can be moved freely, so that the arc-shaped protective plate 1 is always above the patient's chest cavity, supporting and protecting the patient's chest cavity. At the same time, it can be used directly on the hospital bed without the need for the patient to be transferred.

[0023] In order to achieve the purpose of adjusting the distance between the arc-shaped protective plate 1 and the support foot 3, the device adopts the following technical solution: the arc-shaped protective plate 1 has several ventilation holes 101, the lower edges of both sides of the arc-shaped protective plate 1 are rotatably installed with threaded screws 103, the threaded screws 103 are fixedly connected with knobs 104, the support foot 3 is embedded with threaded sleeves 301, the threaded sleeves 301 are threadedly engaged with the threaded screws 103, and the support foot 3 is symmetrically provided with connecting sliding holes 302, which are slidably engaged with the limiting sliding rods 102.

[0024] The ventilation holes 101 can increase air permeability and reduce the weight of the arc-shaped protective plate 1. The knob 104 can drive the threaded screw 103 to rotate. The threaded screw 103 is threadedly engaged with the threaded sleeve 301. Rotating the knob 104 can drive the support foot 3 to move and adjust the distance between the support foot 3 and the arc-shaped protective plate 1. The connecting slide hole 302 is slidably engaged with the limiting slide rod 102 to restrict the support foot 3 to move only up and down.

[0025] In order to achieve the purpose of adjusting the spacing of the locking blocks 204, the device adopts the following technical solution: a bidirectional threaded rod 201 is rotatably installed in the limiting slide groove 2, a threaded through hole 203 is opened in the limiting slider 202, the threaded through hole 203 is threadedly engaged with the bidirectional threaded rod 201, and a limiting ring 402 is fixedly connected to the locking post 401 near the edges of both ends.

[0026] By threading the bidirectional threaded rod 201 into the threaded through hole 203, rotating the bidirectional threaded rod 201 can drive the limiting slider 202 to move, thereby adjusting the distance between the two limiting sliders 202 on one side. The movement of the limiting slider 202 can drive the snap-fit ​​block 204 to move, so that the snap-fit ​​post 401 can be snapped into the snap-fit ​​through hole 205, connecting both ends of the elastic strap 4 to the arc-shaped protective plate 1.

[0027] The working principle and usage process of this utility model are as follows: When using this utility model, the screw rod 103 is rotated using the knob 104 according to the patient's body shape to adjust the distance between the support foot 3 and the arc-shaped protective plate 1. This ensures that when the arc-shaped protective plate 1 is placed on the hospital bed, the support foot 3 can support it so that it fits snugly against the patient's chest cavity. The elastic strap 4 is then placed on the patient's back. Due to the elasticity of the elastic strap 4, pulling both ends of the elastic strap 4 causes the locking posts 401 at both ends to be positioned between the two locking blocks 204 on both sides. Rotating the bidirectional screw rod 201 moves the locking blocks 204 closer together, causing the locking posts 401 to insert into the locking through holes 205, thus fixing the locking posts 401 between the two locking blocks 204. This connects the elastic strap 4 to the arc-shaped protective plate 1. At this time, the elastic strap 4 applies a certain downward pressure to the arc-shaped protective plate 1, fixing it to the hospital bed and preventing it from being moved by the patient's blankets or other coverings.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
