Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of orthopedics, in particular to a medical orthopedic external fixation splint. Background Art
[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the skeletal muscle system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. Fixation splints are required in the process of orthopedic recovery.
[0003] Currently, external fixation splints are needed for external fixation of fractures, soft tissue injuries or neonatal leg and foot deformities. The construction process of the current external fixation splints is cumbersome and requires the use of splints, gauze and straps in combination. Sometimes a plaster model is also required, which requires a high level of professional technical skills from the operator. Utility Model Content
[0004] In order to solve the technical problems raised in the above background technology, the utility model provides a medical orthopedic external fixation splint.
[0005] The utility model is implemented by the following technical solutions: a medical orthopedic external fixation splint, comprising a double-layer TPU foam, a connecting hose and a stop clamp, wherein a solidifying glue flow channel is provided on the inner side of the double-layer TPU foam, auxiliary iron wires are provided at equal intervals on the inner side of the double-layer TPU foam, the connecting hose is connected to one side of the double-layer TPU foam, and one end of the connecting hose is threadedly connected to a solidifying infusion bottle cap, and the stop clamp is provided on the outer side of the connecting hose.
[0006] As a further improvement of the above solution, the edges of the double-layer TPU foam are sealed by hot melting.
[0007] As a further improvement of the above solution, a TPU inner membrane is provided on the inner side of the double-layer TPU foam.
[0008] As a further improvement of the above solution, the double-layer TPU foam is hollow TPU foam.
[0009] As a further improvement of the above solution, the auxiliary iron wire is a bendable and deformable iron wire.
[0010] As a further improvement of the above solution, the two sides inside the flow-stop clamp are extrusion ends of the extrudable connecting hose, and one side of the flow-stop clamp is a movable end, and the flow-stop clamp is provided with latching teeth at equal intervals for the movable end to be engaged.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. After the coagulant is poured into the double-layer TPU foam, the fixed splint is wrapped around the corresponding hand, foot or leg. Under the action of the replica wire, the coagulant solidifies after a few minutes, and a fixed clamping device can be formed on the hand, foot or leg. It can complete the healing of fractures and soft tissue injuries, or prevent foot deformities in newborns, and it can be more convenient during the operation.
[0013] 2. After hot melting, the double-layer TPU foam of the utility model has good sealing performance and can withstand high-intensity pressure, and will not break when the solidified glue is added.
[0014] 3. The double-layer TPU foam of the utility model is designed in a shape that is ergonomically suitable for bandaging human hands and feet.
[0015] 4. The hollow design of the double-layer TPU foam of this invention allows the skin of the hands and feet to partially leak into the air after wrapping, which not only achieves treatment or correction but also allows the skin to breathe. The double-layer TPU foam is breathable, which better ensures that the skin does not itch or ulcerate. BRIEF DESCRIPTION OF THE DRAWINGS
