[0023] The following is further described in detail through specific implementation methods: Embodiment 1:

[0024] As attached Figures 1 to 10 As shown: a bone repair material blending device includes a mixing chamber 1, the mixing chamber 1 includes a first clamping plate 11 and a second clamping plate 12, and the first clamping plate 11 and the second clamping plate 12 are threadedly connected.

[0025] A stirring mechanism for dissolving and stirring different materials is provided in the stirring chamber 1, and the stirring mechanism includes a driving shaft 14, on which a plurality of stirring blades 4 are provided, and between adjacent stirring blades 4 there is provided a receiving chamber for pre-storing materials; the stirring mechanism also includes a driving member fixedly connected to the outer wall of the stirring chamber 1 by screws. In this embodiment, the driving member is a motor 2, and a screw rod 21 is coaxially clamped on the output shaft of the driving member, and a nut seat 22 is slidably fitted on the screw rod 21, and a connecting rod 24 is rotatably fitted on the nut seat 22, and the connecting rod 24 is centered on the screw rod 21. The screw rod 21 is arranged circumferentially, and a first turntable 23 is slidably fitted on the screw rod 21, and the first turntable 23 is welded to the connecting rod 24; the stirring blade 4 is semi-spherical, and a second turntable 41 is integrally formed at the center of the stirring blade 4, the second turntable 41 is rotatably fitted with the drive shaft 14, and both ends of the drive shaft 14 are threadedly connected to the stirring chamber 1, and the drive shaft 14 is slidably fitted with the stirring blade 4; an annular groove 5 is opened on the second turntable 41, and a clamping plate is arranged in the annular groove 5, one end of the clamping plate is rotatably fitted with the second turntable 41, and the other end of the clamping plate is located in the annular groove 5.

[0026] When the connecting rod 24 moves to a distance from the second rotating disk 41, the connecting rod 24 is located in the annular groove 5; when the connecting rod 24 rotates clockwise, the connecting rod 24 abuts against the clamping plate; when the connecting rod 24 rotates counterclockwise, the connecting rod 24 and the clamping plate slide together.

[0027] A plurality of branch pipes 42 are connected inside the stirring blade 4, and a plurality of liquid outlet holes 43 are opened on the stirring blade 4, and the liquid outlet holes 43 are connected to the branch pipes 42; one end of the branch pipe 42 away from the liquid outlet hole 43 is located inside the driving shaft 14, and the other end of the branch pipe 42 away from the liquid outlet hole 43 is connected to the outside.

[0028] The top of the stirring chamber 1 is connected to a liquid inlet pipe 13 for adding a solution, and the bottom of the stirring chamber 1 is connected to a delivery pipe 3 for outputting the material after stirring and mixing. A funnel-shaped transfer tank is opened on the side of the stirring chamber 1 away from the liquid inlet pipe 13, and the transfer tank is connected to the delivery pipe 3. The liquid inlet pipe 13 and the delivery pipe 3 are on the same vertical line. A turning mechanism for automatically stirring the material is provided in the delivery pipe 3. In this embodiment, the turning mechanism is a fan blade that rotates with the delivery pipe 3 to stir and mix the slurry inside the delivery pipe 3.

[0029] In another embodiment, the flipping mechanism includes an arc-shaped moving plate 31, a mounting frame 32 is fixedly connected at the center of the conveying tube 3, and the mounting frame 32 is rotationally matched with one end of the moving plate 31; a slider 33 is fixedly connected to the other end of the moving plate 31, and the slider 33 is slidingly matched with the conveying tube 3.

[0030] The specific implementation process is as follows: First, the doctor installs the materials layer by layer between adjacent stirring plates, and pre-stores different materials to reduce the proportional distribution calculation of temporary proportions and improve work efficiency. At the same time, due to the isolation of the multi-layer stirring plates 4, the materials in the containing chamber are gradually moistened according to the distribution situation to reduce the insolubility of the materials, so that the different layered materials can be fully dissolved and mixed during the stirring process, thereby improving the mixing efficiency.

[0031] The detachable stirring chamber 1 formed by the first clamping plate 11 and the second clamping plate 12 is convenient for disassembling and cleaning the device after use. At the same time, the separated stirring chamber 1 is convenient for disassembling the stirring blade 4 on the driving shaft 14, so that during the installation of the stirring blade 4, the material can be piled up on different stirring blades 4, and then the piled material can be pressed by the stirring blade 4 to form a accommodating chamber between adjacent stirring blades 4 to store the material in advance, thereby facilitating the loading of drugs and improving work efficiency.

[0032] During the stirring process, the motor 2 is started to drive the screw rod 21 to rotate, and the nut seat 22 is driven to move along the screw rod 21 through the screw rod 21 to continuously push the connecting rod 24 to move, and at the same time, the screw rod 21 drives the connecting rod 24 to rotate on the nut seat 22 through the first turntable 23; when the connecting rod 24 is inserted into the annular groove 5 on the second turntable 41, the screw rod 21 drives the connecting rod 24 to rotate clockwise in the annular groove 5. At this time, the connecting rod 24 is abutted against the clamping plate, so that the connecting rod 24 pushes the second turntable 41 to move through the clamping plate, so as to continuously push the stirring piece 4 fixedly connected to the second turntable 41 to rotate, and then the stirring pieces 4 at different heights are rotated in the stirring chamber 1 in turn to form multiple stirring effects, so as to facilitate the mixing and dissolution of different materials in the stirring chamber 1 by solvents. When the screw rod 21 drives the connecting rod 24 to rotate counterclockwise in the annular groove 5, the connecting rod 24 and the clamping plate slide in cooperation, and the clamping plate is subjected to little force during the contact process with the connecting rod 24. The second turntable 41 is subjected to the resistance of the stirring plate 4 and the external solvent, so that the stirring plate 4 remains stationary, and the screw rod 21 drives the connecting rod 24 to move to the side away from the annular groove 5, so as to realize the separation of the connecting rod 24 and the second turntable 41.

[0033] At the same time, by setting the liquid outlet 43, the branch pipe 42 can be used to inject the solution and the material between the stirring blades 4 to moisten the material in advance, so as to reduce the influence of the surface tension of water molecules in the process of contact between the material and water, which causes the material to be wrapped and form a clumping substance that is not easy to dissolve, so as to facilitate the dissolution of the material in the solution during the stirring and mixing process, thereby improving the dissolution efficiency.

[0034] After the mixing is completed, the doctor rotates the direction of the mixing chamber 1 and confirms the position of the delivery tube 3 using the indication of the liquid inlet tube 13, so that the material inside the mixing chamber 1 naturally falls into the delivery tube 3 due to gravity. Then, the material inside the mixing chamber 1 is transferred through a funnel-shaped transfer trough to facilitate the flow of the mixed material inside the mixing chamber 1. Finally, the slurry inside the delivery tube 3 is used to push the moving plate 31 to rotate inside the delivery tube 3, so that the slurry inside the delivery tube 3 is rotated and mixed during the rotation of the moving plate 31, so as to reduce the sedimentation of the slurry inside the delivery tube 3.

[0035] Embodiment 2:

[0036] The difference from the first embodiment is that a plurality of grab teeth 44 are welded on the stirring blade 4 .

[0037] The specific implementation process is as follows: during the layer-by-layer rotation of the stirring blade 4, the material layer inside the containing chamber is scraped by the grabbing teeth 44 to form a gradual dissolution. At the same time, during the movement of the grabbing teeth 44 in the stirring chamber 1, the bubbles generated during the stirring process are punctured to facilitate the full mixing of the material inside the containing chamber with the solution.

[0038] Embodiment 3:

[0039] The difference from the second embodiment is that a top block (not shown in the figure) is provided between adjacent stirring blades 4, and the top block is fixedly connected to the stirring blade.

[0040] The specific implementation process is as follows: during the process of adding materials, the adjacent stirring blades 4 are supported by the top block to control the distance between the adjacent stirring blades 4 to form a containing chamber, ensuring that the material accumulated inside the containing chamber is in a moderate pressing state to facilitate the dissolution of the material in the subsequent mixing process.

[0041] Embodiment 4:

[0042] The difference from Example 3 is that the side of the delivery pipe 3 close to the moving plate 31 is connected to an elliptical detection chamber, a pressure sensor is provided between the detection chamber and the moving plate 31, and the pressure sensor is electrically connected to a control panel (not shown in the figure); the pressure sensor is used to measure the real-time pressure value applied by the moving plate 31 to the inner wall of the detection chamber, and send the real-time pressure value to the control panel; The control panel is electrically connected to a display panel (not shown in the figure), and the control panel is used to draw a waveform graph based on the real-time pressure value, and send the waveform graph to the display panel for display.

[0043] For example, the real-time pressure value applied by the moving plate 31 to the inside of the detection chamber is confirmed by using a pressure sensor to determine the type of slurry in the gap between the moving plate 31 and the conveying pipe 3. Under normal circumstances, the materials have a certain viscosity and supporting strength after mixing. Therefore, during the process of the moving plate 31 and the squeezing of the slurry, the slurry inside the current conveying pipe 3 will form support and exert pressure on the pressure sensor.

[0044] If the slurry is thinner, the slurry support strength is lower, and the real-time pressure value collected by the pressure sensor decreases accordingly; if the slurry is thicker, the slurry support strength is greater, and the real-time pressure value collected by the pressure sensor increases accordingly, so as to test the mixing effect of the materials. In the material mixing process, based on the uniformly mixed materials, the real-time pressure value of the pressure sensor should fluctuate within a certain range, and the doctor can judge whether the current material mixing uniformity meets the standard based on the waveform diagram.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
