Description

Technical Field

[0001] This invention relates to the field of plaster cast preparation technology, and more particularly to a plaster cast preparation device for hand and foot surgical fractures. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. In bone injuries and diseases, plaster casts are also used to fix fracture sites, fix swollen and injured joints, support and fix sprained ligaments and muscle tissues, and make molds, prostheses and other assistive devices, protective supports for burn sites, etc.

[0003] For example, the Chinese patent "CN208808870U A plaster mixing device for medical orthopedics" includes a base, with a mixing device body fixedly connected to the top of the base. A feed inlet is connected to the top left side of the mixing device body. A fixing rod is fixedly connected to the left side of the top of the mixing device body, and a support rod is fixedly connected to the right side of the fixing rod. A first motor is movably connected to the top of the mixing device body, and a slider is fixedly connected to the top of the first motor. This invention has the advantage of uniformly mixing plaster.

[0004] Most commercially available plaster cast mixing devices for fractures adopt an integrated structure. This design makes the disassembly and assembly process cumbersome and makes it difficult to disassemble and thoroughly clean the device. If the residual paste-like plaster inside the device is not cleaned in time after use, it will gradually solidify, which will have an adverse effect on the quality and effect of subsequent plaster mixing. Summary of the Invention

[0005] This invention relates to a plaster plaster mixing device for hand and foot surgical fractures, which solves the problem that existing plaster plaster mixing devices generally adopt an integrated structure, which makes the disassembly and assembly process cumbersome, makes it difficult to disassemble and thoroughly clean the device, and if the residual paste plaster inside the device is not cleaned in time after use, it will gradually solidify, which will have an adverse effect on subsequent plaster mixing.

[0006] In a first aspect, this invention provides a plaster cast preparation device for hand and foot surgical fractures, specifically comprising: a supporting base, a mixing vessel, fastening bolts A, an L-shaped support, a screw feeder, a drive motor, a mixing paddle head, a solenoid valve, a guide pipe, and bolts B; the mixing vessel is placed inside the top of the supporting base, the bottom of the mixing vessel being arc-shaped, and fastening bolts A are connected inside the top of the supporting base; an L-shaped support is connected to the outside of the mixing vessel, and a screw feeder is fixedly connected inside the L-shaped support; two bolts B are connected inside the L-shaped support, and bolts B are connected to the mixing vessel; a drive motor is fixedly installed on the top of the L-shaped support, and a mixing paddle head is connected to the bottom of the L-shaped support, with the drive shaft of the drive motor connected to the mixing paddle head; a guide pipe is fixedly connected inside the L-shaped support, and a solenoid valve is connected to the top of the guide pipe; the screw feeder, drive motor, and screw feeder are connected to a PLC control panel via wiring.

[0007] Furthermore, the discharge end of the screw feeder is located inside the mixing tank, the bottom end of the guide vertical pipe is located inside the mixing tank, and the top end of the guide vertical pipe is connected to the water supply pipeline through a solenoid valve. The screw feeder and the solenoid valve are controlled by the PLC control panel. The required amount of gypsum is input into the PLC control panel. According to the proportioning and metering set by the PLC control panel, the opening time of the screw feeder and the solenoid valve are controlled respectively to add a certain amount of gypsum powder and water into the mixing tank.

[0008] Furthermore, the top of the mixing paddle head is rotatably connected to the L-shaped support, and the bottom of the mixing paddle head is located inside the mixing vessel. The bottom of the mixing paddle head is arc-shaped and contacts the inner wall of the mixing vessel. After the gypsum powder and water are added to the mixing vessel, the running time of the drive motor is adjusted through the PLC control panel according to the input amount of gypsum used. The drive motor drives the mixing paddle head to rotate, and the mixing paddle head thoroughly stirs and mixes the gypsum powder and water.

[0009] Furthermore, the L-shaped support base is symmetrically provided with top support grooves on its inner side, the top of the mixing vessel is located in the top support grooves, the mixing vessel is provided with a limiting groove near the top, and the screw feeder is located in the limiting groove.

[0010] Furthermore, the mixing vessel is provided with two positioning holes near the top, which are symmetrically located on the left and right sides of the limiting groove. The bottom of the L-shaped support is symmetrically provided with screw holes B, which are connected to the positioning holes.

[0011] Furthermore, the bolt B is threaded into the screw hole B, and the inner end of the bolt B is connected to the positioning hole. When the L-shaped support is connected to the top of the mixing vessel, the edge of the mixing vessel is located in the top support groove, which supports the L-shaped support. The screw feeder is in the limiting groove, preventing the L-shaped support from moving left or right. At this time, the screw hole B and the positioning hole are in a connected state. Tightening the bolt B moves the end of the bolt B into the positioning hole, which fixes the L-shaped support.

[0012] Furthermore, the outer side of the mixing vessel contacts the inner side of the support base, and three side support blocks are arranged around the outer side of the mixing vessel, with the bottom of the side support blocks contacting the top of the support base.

[0013] Furthermore, the top of the support base is provided with a screw hole A, and the fastening bolt A is threaded into the screw hole A. The end of the fastening bolt A contacts the outside of the mixing vessel. When the mixing vessel is placed on the top of the support base, the mixing vessel is supported by the side support block, and the fastening bolt A is tightened so that the end of the fastening bolt A contacts the mixing vessel, thereby fixing the mixing vessel.

[0014] This invention provides a plaster cast mixing device for hand and foot surgical fractures, which has the following beneficial effects: In use, this invention utilizes a PLC control panel to precisely control the screw feeder and solenoid valve. Simply input the required amount of plaster into the PLC control panel, and the system will precisely control the opening duration of the screw feeder and solenoid valve according to the pre-set mixing parameters. This ensures that a precise amount of plaster powder and water is accurately injected into the mixing vessel, thus strictly guaranteeing the metering accuracy during plaster preparation. After the plaster powder and water are successfully injected into the mixing vessel, the PLC control panel will precisely adjust the running time of the drive motor based on the previously input amount of plaster. Driven by the motor, the mixing paddle head begins to rotate at high speed, thoroughly and efficiently stirring the plaster powder and water in the vessel, ensuring uniform mixing and ultimately producing a paste-like plaster that meets the requirements for bone fixation.

[0015] In addition, when the L-shaped support is connected to the top of the mixing vessel, the rim of the mixing vessel is located in the top support groove, which supports the L-shaped support. The screw feeder is in the limiting groove, preventing the L-shaped support from moving left or right. At this time, the screw hole B and the positioning hole are connected. Tightening the bolt B moves the end of the bolt B into the positioning hole, which fixes the L-shaped support and ensures the firmness of the connection between the L-shaped support and the mixing vessel, making assembly simpler and faster.

[0016] In addition, when the mixing vessel is placed on top of the support frame, it is supported by the side support blocks, and the fastening bolts A are tightened so that the ends of the fastening bolts A contact the mixing vessel, thus fixing the mixing vessel. After the gypsum is mixed, the two bolts B are loosened so that the ends of the bolts B separate from the positioning holes, and the L-shaped support is released. The L-shaped support can then be removed from the top of the mixing vessel. The fastening bolts A are then loosened so that the ends of the fastening bolts A separate from the mixing vessel, and the mixing vessel is released. The mixing vessel can then be removed from the top of the support frame, and the mixing vessel and the mixing impeller are cleaned separately. This effectively prevents the paste-like gypsum residue from hardening on the mixing vessel and the mixing impeller, which would affect the effect of the next gypsum mixing application.
