[0039] Reference Figure 1 and Figure 2, a child wound medicine nursing device, comprising a ring-shaped base 1, a belt 2, a supporting mechanism 3, an injection mechanism 4 and a displacement mechanism 5, the ring-shaped base 1 is provided with the belt 2 on both sides, the supporting mechanism 3 for supporting the medicine syringe for wound treatment is arranged on the ring-shaped base 1, and the supporting mechanism 3 comprises a docking ring 31, a fixed plate 32, a supporting rod 33, a supporting cylinder 34, a supporting frame 35 and a linkage unit, the injection mechanism 4 for pushing the syringe is arranged on the supporting cylinder 34, and the displacement mechanism 5 for pushing the linkage unit linkage is arranged on one side of the supporting frame 35, the application realizes the quick switching use of multiple syringes, converts the replacement action in the traditional operation which needs to interrupt the treatment into a continuous treatment process, replaces the manual pressing operation with a mechanical pushing system, ensures that the pushing force is kept constant every time, avoids the phenomenon that the medicine is not uniformly sprayed due to uneven force, the angle-adjustable supporting mechanism 3 enables medical staff to quickly adjust the spraying angle according to the wound position, and the precision of medicine coverage is improved, the application realizes the synchronous loading of at least two syringes through multiple clamping plates in the supporting frame 35, significantly reduces the number of operation interruptions, converts the pressing action into accurate linear pushing through the mechanical cooperation of the displacement mechanism 5 and the linkage unit, eliminates the human force fluctuation, and through the composite motion mechanism of the docking ring 31 and the supporting rod 33, the medicine spraying direction can be adjusted in real time according to the wound position.
[0040] Specifically, the ring-shaped base 1 is fixed on the head of the child through the belt 2, displacement of the device in the operation process is avoided, the supporting cylinder 34 is rotated around the axis of the ring-shaped base by the docking ring 31, the supporting rod 33 realizes the pitch angle adjustment through the hinge joint of the fixed plate 32 and the docking ring 31, the axis of the supporting cylinder 34 is aligned with the wound area, the two groups of belt pulleys 36 in the supporting frame 35 drive the first clamping plate 38 and the second clamping plate 39 to move towards each other through the belt 37, and the fixed positions of the syringes in equidistant arrangement are formed. When the displacement mechanism 5 pushes the sliding rod 51, the synchronous plate 52 drives the adjusting rod 55 to drive the ratchet wheel 53 to rotate, so that the belt pulleys 36 are synchronously rotated to drive the clamping plate group to move, the push plate 43 of the injection mechanism 4 is driven by the driving rod 42, a vertical downward pushing force is applied to the piston of the medicine syringe 310 through the guiding action of the cross support frame 41, and the lever mechanism composed of the clamping block 49 and the linkage rod 46 converts the pressing action into stable linear pushing force.
[0041] Referring to Figure 3 and Figure 4 , specifically, the docking ring 31 is rotationally connected to the ring-shaped base 1, the fixed plate 32 is fixed to the docking ring 31, one end of the supporting rod 33 is rotationally connected to the fixed plate 32, and the other end is fixed to the supporting cylinder 34, the supporting cylinder 34 is coaxially arranged with the docking ring 31, the supporting frame 35 is radially fixed to the supporting cylinder 34, and the linkage unit is arranged in the supporting frame 35.
[0042] Referring to Figure 5 and Figure 6In the embodiment of the present application, the linkage unit comprises a belt pulley 36, a belt 37, a first clamping plate 38, a second clamping plate 39 and a drug injector 310. The present application realizes quick switching and accurate positioning of multiple drug injectors 310, and the operation time is greatly shortened compared with the traditional mode, the force deviation amplitude is greatly reduced, the symmetrical belt 37 transmission layout greatly reduces the injector switching track error, and ensures the accurate positioning of the advancing mechanism and the injector piston rod.
[0043] The two belt pulleys 36 are symmetrically arranged and rotationally connected at both ends of the support frame 35. The belt 37 is arranged between the two adjacent belt pulleys 36, and the whole structure composed of the belt pulley 36 and the belt 37 is arranged in parallel with two groups in the support frame 35. The first clamping plate 38 is fixed to the outer wall of one of the two groups of belts 37, and the second clamping plate 39 is fixed to the outer wall of the other group of belts 37. The first clamping plate 38 and the second clamping plate 39 are arranged one by one and equidistantly, and the drug injector 310 is clamped between the first clamping plate 38 and the second clamping plate 39.
[0044] Specifically, the two groups of belt transmission systems form a mirror image symmetric layout inside the support frame 35. When the driving mechanism drives the belt pulley to rotate, the two groups of belt pulleys 36 move synchronously towards each other. The first clamping plate 38 and the second clamping plate 39 maintain a corresponding relationship during the movement of the belt 37. When the drug injectors 310 carrying different drugs are sequentially placed in the adjacent clamping plate groups, the equidistant design of the clamping plate spacing makes the injector axis perpendicular to the transmission direction, forming stable radial constraint. During the continuous transmission of the belt, when the injector moves with the clamping plate group to the predetermined station, the advancing mechanism can accurately align the injector piston rod to perform pressing operation. This mechanical transmission mode realizes the orderly arrangement of multiple injectors through the preset clamping plate spacing, and eliminates the positioning error when manually replacing the injector.
[0045] In the embodiment of the present application, the injection mechanism 4 comprises a cross support frame 41, a driving rod 42, a push plate 43 and a driving pressing unit. The cross support frame 41 is fixed to the top of the supporting cylinder 34, the driving rod 42 is slidingly connected at the center of the cross support frame 41, and the push plate 43 is fixed to the bottom end of the driving rod 42 and abuts against the top end of the piston rod of the drug injector 310.
[0046] Specifically, the cross support frame 41 provides vertical guidance for the driving rod 42 through rigid fixation, ensuring that the push plate 43 moves along a preset trajectory. When the operator presses the pressing rod 45, the linkage rod 46 converts the rotary motion into linear downward movement of the driving rod 42, and the push plate 43 exerts a vertical downward pushing force on the piston rod of the drug injector 310. The clamping block 49 and the limiting plate 44 jointly limit the movement stroke of the driving rod 42, preventing excessive pressing from causing excessive displacement of the piston rod. After pressing is completed, the first return spring 48 pushes the clamping block 49 to reset, driving the driving rod 42 and the push plate 43 to return to the initial position, ready for the next pressing operation.
[0047] The present application effectively solves the problem of spray pressure deviation caused by unstable manual force. The mechanical transmission mechanism converts the manual pressing action into stable linear pushing force, ensuring that the piston rod of the drug injector 310 maintains uniform linear motion during the pushing process. The rotary constraint of the linkage rod 46 and the limiting plate 44 eliminates lateral force interference, avoiding the deviation of the push plate 43 causing the deviation of the drug injection angle. The double limiting structure formed by the clamping block 49 and the upper and lower positioning structure of the cross support frame 41 prevents the radial deviation of the driving rod 42 during the movement process, ensuring the consistency of the output pressure of each pressing action.
[0048] Referring to Figure 7 and Figure 8 , specifically, in the embodiment of the present application, the active pressing unit includes a limiting plate 44, a pressing rod 45, a linkage rod 46, and a clamping block 49. The present application realizes the linear pushing and automatic resetting of the piston rod of the drug injector 310, effectively eliminating the pressure fluctuations caused by the deviation of the force direction and incomplete resetting in manual operation. The stable contact state between the push plate 43 and the piston rod ensures the consistency of the force direction during continuous pressing, avoiding uneven drug injection or the risk of secondary damage to the wound caused by pressure deviation.
[0049] The limiting plate 44 is fixed at the top end of the driving rod 42, and the clamping block 49 is fixed on the driving rod 42 above the cross support frame 41. One end of the pressing rod 45 is rotationally connected to the clamping block 49, and one end of the linkage rod 46 is rotationally connected to the pressing rod 45, and the other end is rotationally connected to the limiting plate 44.
[0050] Specifically, when the medical staff applies downward pressure to the pressing rod 45, the pressing rod 45 produces rotary motion around the hinge point of the clamping block 49. The linkage rod 46 converts the rotary motion into vertical displacement of the driving rod 42 under the rotary constraint of the limiting plate 44. The double constraint formed by the clamping block 49 and the upper and lower positioning of the cross support frame 41 ensures the linear movement of the driving rod 42 along the preset trajectory. The rotary connection of the linkage rod 46 and the limiting plate 44 eliminates the lateral component force, ensuring that the pushing force of the push plate 43 on the piston rod of the drug injector 310 remains axial consistency. The mechanical transmission mechanism amplifies the force through the leverage ratio, converting the manual pressing action into stable linear pushing force.
[0051] In the embodiment of the present application, the injection mechanism 4 further comprises a guide rod 47 and a first reset spring 48, the guide rod 47 is fixed between the push plate 43 and the clamping block 49 and is in sliding connection with the cross support frame 41, and the first reset spring 48 is sleeved outside the driving rod 42 and abuts between the cross support frame 41 and the clamping block 49.
[0052] The present application realizes the linear propulsion and automatic reset of the piston rod of the drug injector 310, effectively eliminates the pressure fluctuation caused by the deviation of the force direction in manual operation and the incomplete reset, and the stable contact state between the push plate 43 and the piston rod guarantees the consistency of the force direction in continuous pressing, thereby avoiding the uneven drug injection or the risk of secondary damage to the wound caused by the pressure deviation.
[0053] Specifically, when the driving rod 42 is pressed by an external force, the sliding cooperation between the guide rod 47 and the cross support frame 41 limits the radial displacement of the driving rod 42, so that the push plate 43 uniformly pushes the piston rod of the drug injector 310 in a straight line direction. After pressing, the first reset spring 48 drives the clamping block 49 to move reversely by the stored elastic potential energy, and drives the driving rod 42 to automatically reset to the initial position. In this process, the pre-tightening force of the spring continuously acts on the clamping block 49, avoiding the gap between the push plate 43 and the piston rod, and ensuring the consistent initial contact state of each pressing action.
[0054] With reference to Figure 9 and Figure 10 In the embodiment of the present application, the displacement mechanism 5 comprises a sliding rod 51, a synchronous plate 52, a ratchet wheel 53, a clamping seat 54, an adjusting rod 55 and a second reset spring 56. The present application realizes the automatic switching function of multiple drug injectors 310, eliminates the time loss of manual disassembly and assembly, reduces the restlessness risk of child patients caused by prolonged operation time, the meshing transmission mechanism of the ratchet wheel 53 and the adjusting rod 55 guarantees the positioning accuracy of the drug injection process, avoids the abnormal drug distribution caused by the device rollback in the injection process, and the rigid linkage structure of the synchronous plate 52 and the sliding rod 51 enables the external driving force to be uniformly transmitted to the belt pulley 36, thereby ensuring the consistency of the propulsion pressure when different drug injectors 310 are switched, and reducing the secondary damage to the wound caused by the pressure deviation.

[0056] Specifically, when the sliding rods 51 are axially displaced by external driving, the synchronous plate 52 drives the adjusting rod 55 to rotate around the clamping sleeve 54, the end of the adjusting rod 55 slides along the tooth surface of the ratchet 53 and drives the ratchet 53 to rotate, the second reset spring 56 is elastically deformed during the swinging of the adjusting rod 55, and the adjusting rod 55 is reset to the initial angle after the driving is completed, the coaxial fixing structure of the ratchet 53 and the belt pulley 36 converts the linear displacement into the step-by-step rotation of the belt pulley 36, the driving belt drives the clamped medicine injector 310 to move along the fixed track, the one-way rotation characteristic of the ratchet 53 is realized through the tooth shape engagement, and the position deviation of the medicine injector caused by the reverse rotation of the belt pulley 36 due to external force can be prevented.
[0057] Optionally, the displacement mechanism 5 further comprises a connecting plate 57 and a driven rod 58, the connecting plate 57 is fixed on the plurality of sliding rods 51 at one end outside the support frame 35, and the driven rod 58 is rotatably connected to the connecting plate 57 at one end and rotatably connected to the clamping block 49 at the other end.
[0058] The application realizes the automatic sequential switching of multiple medicine injectors 310, completes the continuous bolus injection of different liquid medicines without interrupting the medicine administration process, the mechanical linkage structure guarantees the linear transmission characteristic of the bolus injection pressure, avoids the pressure mutation caused by manual operation, and effectively reduces the risk of secondary injury of the wound caused by uneven force.
[0059] Specifically, when the sliding rods 51 are axially displaced by external force, the connecting plate 57 drives the driven rod 58 to rotate around the fixed fulcrum, the rotating action of the end of the driven rod 58 is transmitted to the clamping block 49, the clamping block 49 is forced to deflect along the preset track, the deflection movement of the clamping block 49 synchronously drives the driving rod 42 to axially displace, and then controls the pressing action of the push plate 43 on the medicine injector 310, the linkage mechanism makes the displacement amount of the sliding rod 51 and the stroke of the push plate 43 form a proportional relationship, and ensures that the starting position of the bolus injection action is automatically reset after each injector switching.
[0060] The inner side of the support frame 35 is rotatably connected with a ratchet pawl 59, one end of the ratchet pawl 59 is slidably abutted at the edge of the ratchet 53, and a third reset spring 510 is arranged between the support frame 35 and the ratchet pawl 59, the application effectively prevents the positioning failure of the medicine injector 310 caused by the rotation of the ratchet 53 during the progressive displacement, ensures the accurate clamping of the injectors by the multiple clamping plates, the continuous contact state of the ratchet pawl 59 and the ratchet 53 maintains the stability of the displacement mechanism 5, avoids the deviation of the medicine injection pressure caused by the force fluctuation, reduces the risk of secondary injury of the wound, and the automatic reset characteristic of the third reset spring 510 reduces the operation steps and improves the work efficiency of medical staff.
