Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a high-pressure injector capable of preventing no-load start-up. Background Art

[0002] The wheel-pressure high-pressure injector mainly includes a main unit, an electronic control component is arranged inside the main unit, and a tube pressing platform is arranged on the upper side. A wheel-pressure mechanism and a tube groove passing through the wheel-pressure mechanism are arranged in the tube pressing platform. A lifting platform is arranged at the tube inlet end of the wheel-pressure mechanism, and the lifting platform includes a main body for carrying the infusion tube and a lifting rod fixedly arranged under the main body. The lifting rod passes through the tube pressing platform and is controlled by the electronic control component. The lifting platform sends the infusion tube into or out of the pressing plane of the wheel-pressure mechanism, so that the main unit can automatically disassemble and assemble the infusion tube.

[0003] The problem is that the host cannot determine whether there is an infusion tube placed in the lifting platform at the current state, and the lifting platform will automatically descend without a tube, resulting in an empty pressure wheel, such as a human error in inputting a descending command. At this time, manual intervention is required to re-control the lifting platform to rise and stop the wheel pressure mechanism. High-pressure injectors are used in rigorous surgical environments, so how to avoid empty operation and avoid interfering with the normal operation is a technical problem that needs to be solved in the industry.

[0021] like Figures 1 to 3As shown, a high-pressure injector with anti-no-load start described in the utility model includes a main body 10, an electronic control component is arranged in the main body 10, and a tube pressing platform is arranged on the upper side of the main body 10. A wheel pressing mechanism 12 and a tube groove 11 passing through the wheel pressing mechanism 12 are arranged in the tube pressing platform. A lifting platform is arranged at the tube inlet end of the wheel pressing mechanism 12, and the lifting platform includes a main body 20 for carrying an infusion tube 30 and a lifting rod fixedly arranged under the main body 20. The lifting rod is controlled by the electronic control component after passing through the tube pressing platform. The lifting platform is provided with a vertically extending baffle 21 on one side of the main body 20, and the lower end of the baffle 21 is connected to the lower end of the main body 20 to form a U-shaped groove 22. The U-shaped groove 22 is located above the tube groove 11 and has the same extension direction as the tube groove 11.

[0022] A clamping block 23 is provided at a position of the baffle plate 21 near the U-shaped groove 22. A second metal sheet 27 is provided on the upper end surface of the baffle plate 21, and the second metal sheet 27 is electrically connected to the electronic control component through a copper wire. A fixing sheet 24 is fixedly provided on the upper end surface of the body 20 near the edge of the baffle plate 21. The fixing sheet 24 is fixedly connected to a spring sheet 25 near the edge of the baffle plate 21, and the spring sheet 25 is fixedly connected to a first metal sheet 26 near the edge of the baffle plate 21. The first metal sheet 26 is electrically connected to the electronic control component through another copper wire. When the first metal sheet 26 is naturally laid flat above the baffle plate 21, it is electrically connected to the second metal sheet 27.

[0023] Another clamping block symmetrical to the clamping block 23 is disposed at a position of the main body 20 near the U-shaped groove 22 .

[0024] The copper wire connecting the second metal sheet 27 and the electric control component extends along the baffle 21, the outside of the U-shaped groove 22 and the bottom of the body 20 to the inside of the lifting rod, and then passes through the pressing tube platform to connect with the electric control component.

[0025] The copper wire connecting the first metal sheet 26 and the electric control component extends along the spring sheet 25, the fixing sheet 24, and the body 20 to the inside of the lifting rod, and then passes through the pressing tube platform to connect with the electric control component.

[0026] The second metal sheet 27 is located in the middle of the upper end surface of the fixing sheet 24 .

[0027] The working principle of the high-pressure injector for preventing no-load start described in the utility model is as follows:

[0028] In the original state, the lifting platform is not equipped with an infusion tube, and the fixing plate 24, the spring plate 25 and the first metal plate 26 are placed horizontally. The first metal plate 26 is naturally attached to the second metal plate 27 and is electrically connected to each other. Figure 3 The electric control component can detect the connection status of the two metal sheets through the two copper wires.

[0029] When the infusion tube 30 is loaded, the infusion tube 30 is manually pushed in from the top of the U-shaped groove 22. First, the spring sheet 25 is pressed down, so that the first metal sheet 26 is pressed down and away from the second metal sheet 27. When the infusion tube 30 reaches the bottom of the U-shaped groove 22, it is clamped and fixed by the clamping block 23. At this time, the spring sheet 25 rebounds naturally, but the baffle 21 blocks the first metal sheet 26. The stable state is as follows Figure 4 As shown, the electronic control component detects that the two metal sheets are separated through two copper wires and determines that the current state is tube loading. When the manual input lift table lowering command, the host allows the lift table to descend and operate according to the normal process.

[0030] When the infusion tube 30 is unloaded, Figure 4 In the state shown, the infusion tube 30 is pulled upward and removed. First, it is separated from the limit of the block 23, and then the elastic sheet 25 is pushed up to make the first metal sheet 26 separate from the baffle 21. The infusion tube 30 is separated from the gap between the first metal sheet 26 and the baffle 21. Figure 5 Due to the elastic effect of the spring sheet 25, the first metal sheet 26 will swing down and return to the Figure 3 The electronic control component detects that the two metal sheets are in contact through two copper wires and determines that the current state is no pipe. When the manual input of the command to lower the lifting platform is wrong, the host prohibits the lifting platform from descending to avoid no-load operation.

[0031] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
