[0005] To address the shortcomings of existing technologies, this utility model provides a spraying device for clinical nursing, which solves the following problems of existing spraying devices for clinical nursing: traditional spraying devices require medical staff to operate them by hand for a long time to spray disinfectant inside the hospital, which can easily lead to fatigue and injury to the hands of medical staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for clinical nursing, comprising a spraying device, wherein a support mechanism is provided on the front side of the spraying device for automatically spraying medication in multiple directions, and the support mechanism includes:

[0007] The universal unit, located at the front of the spraying device, includes a support rod. A rotating frame is rotatably mounted on the front of one end of the support rod, and a rotating circular frame is rotatably mounted inside the rotating frame. A forearm is rotatably mounted on the bottom of the rotating circular frame. A mounting base is fixedly mounted on one side of the support rod, and a large arm is rotatably mounted on the inner side of the mounting base. One end of the large arm is rotatably connected to the forearm. By rotating the rotating frame and driving the large arm and forearm to rotate the rotating circular frame, the fixed component at the top of the rotating circular frame can be rotated in multiple directions (left, right, up, and down) for spraying.

[0008] The rocker unit is located above the support rod and is used to control the operation of the universal joint.

[0009] Preferably, a second motor is fixedly installed at the bottom front end of the support rod, and the output end of the second motor passes through the support rod and is fixedly connected to the rotating frame. A first motor is fixedly installed on the outside of the mounting base, and the output end of the first motor passes through the mounting base and is fixedly connected to the boom.

[0010] Preferably, the rocker unit includes a rocker base fixedly installed on the top of the support rod. A button is fixedly installed on the top of the rocker base. The first motor is driven to run by pushing and pulling the rocker base rod column back and forth. The first motor drives the rotating frame to rotate up and down through the upper arm and the lower arm. The second motor is driven to run by pushing and pulling the rod column left and right. The second motor drives the rotating frame to rotate.

[0011] Preferably, the spraying device includes a medicine box, and a support rod is fixedly installed on the left side of the medicine box. A connecting pipe is fixedly installed on the left side of the medicine box, and a spray pipe is fixedly installed at the output end of the connecting pipe.

[0012] Preferably, the fixing assembly includes a fixing frame fixedly installed on the top of the rotating round frame, a lower clamping block fixedly installed at the bottom of the inner cavity of the fixing frame, a limiting slide post fixedly installed at the top of the lower clamping block, and an upper clamping block slidably installed on the surface of the limiting slide post.

[0014] This invention provides a spray device for clinical nursing. Compared with the prior art, it has the following advantages:

[0015] 1. This clinical nursing spraying device features a multi-joint structure formed by a rotating frame hinged at the front end of the support rod and a rotating circular frame, connected by an upper arm and a lower arm. Combined with the coordinated drive of the first and second motors, it enables multi-degree-of-freedom adjustment of the spray nozzle's left-right rotation and up-down pitch. The operator only needs to push or pull the lever column forward / backward / left / right to trigger the motor movement, transforming manual operation into precise directional control driven by a motor. This significantly reduces the hand strain on medical staff during prolonged disinfection spraying and improves operational comfort.

[0016] 2. This clinical nursing spraying device uses a rotating threaded knob to drive the upper clamping block downwards along a limiting slide post, which engages with the lower clamping block with a V-groove to rigidly lock the spray nozzle. The sliding design of the limiting block and the limiting groove ensures no displacement during clamping. Crucially, the rubber pads embedded inside the double clamping blocks increase friction to prevent the spray nozzle from slipping out, while also buffering vibration. This modular design not only enables quick assembly and disassembly and secure fixation of the spray nozzle, but also allows the device to adapt to different pipe diameters via the V-groove, enabling it to flexibly meet diverse clinical spraying needs.

A large arm 216 is rotatably mounted on the inner side of the mounting base 215. One end of the large arm 216 is rotatably connected to the small arm 214. By rotating the rotating frame 212 and driving the large arm 216 and the small arm 214 to rotate the rotating circular frame 213, the fixed component 3 at the top of the rotating circular frame 213 can be rotated in multiple directions (left, right, up, and down) for spraying.

[0026] The rocker unit 22 is located above the support rod 211 and is used to control the operation of the universal unit 21.

[0027] Multi-directional adjustment of the nozzle is achieved through the hinged linkage of the support rod 211, rotating frame 212, rotating circular frame 213 with the upper arm 216 and lower arm 214.

[0028] In this embodiment, a second motor 218 is fixedly installed at the bottom front end of the support rod 211, and the output end of the second motor 218 passes through the support rod 211 and is fixedly connected to the rotating frame 212. A first motor 217 is fixedly installed on the outside of the mounting base 215, and the output end of the first motor 217 passes through the mounting base 215 and is fixedly connected to the upper arm 216.

[0029] The first motor 217 achieves nozzle pitch through the boom-arm mechanism, while the second motor 218 directly controls the rotating frame to achieve horizontal steering.

[0030] In this embodiment, the rocker unit 22 includes a rocker base 221 fixedly installed on the top of the support rod 211. A button 222 is fixedly installed on the top of the rocker base 221. The first motor 217 is driven to run by pushing and pulling the rocker base 221 rod. The first motor 217 drives the rotating frame 213 to rotate up and down through the large arm 216 and the small arm 214. The second motor 218 is driven to run by pushing and pulling the rod left and right. The second motor 218 drives the rotating frame 212 to rotate the rotating frame 213.

[0031] Manual operation is converted into an electrical signal, which triggers the motor to run through the pushing and pulling action of the rocker arm 221, and the spraying of disinfectant is achieved by pressing the button 222.

[0032] In this embodiment, the spraying device 1 includes a medicine box 11, and a support rod 211 is fixedly installed on the left side of the medicine box 11.

[0033] In this embodiment, the fixing component 3 includes a fixing frame 31 fixedly installed on the top of the rotating round frame 213. A lower clamping block 32 is fixedly installed at the bottom of the inner cavity of the fixing frame 31. A limiting slide post 34 is fixedly installed at the top of the lower clamping block 32, and an upper clamping block 35 is slidably installed on the surface of the limiting slide post 34. A threaded button post 36 is threaded through the top of the fixing frame 31, and the bottom end of the threaded button post 36 is rotatably connected to the upper clamping block 35. The upper clamping block 35 is driven to move downward by rotating the threaded button post 36, thereby clamping and fixing the nozzle 13.

[0034] The upper clamping block 35 is driven to move downward by the threaded button 36, and it cooperates with the lower clamping block 32 to lock the nozzle.

[0035] In this embodiment, rubber pads 33 are fixedly installed on the inner V-shaped grooves of both the lower clamping block 32 and the upper clamping block 35. The rubber pads 33 increase the friction of the lower clamping block 32 and the upper clamping block 35 clamping the nozzle 13. A limiting groove 37 is opened on the inner side of the fixing frame 31. A limiting block 38 is fixedly installed on one side of the upper clamping block 35, and the limiting block 38 slides inside the limiting groove 37 to limit the movement of the upper clamping block 35.

[0036] Rubber pad 33 increases friction and prevents slipping, while limit block 38 and limit groove 37 constrain the clamping trajectory.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, first, place the nozzle 13 between the upper clamping block 35 and the lower clamping block 32, and rotate the threaded knob 36 to move the upper clamping block 35 downward to clamp the nozzle 13.

[0039] Then, the user pushes the upper rod of the rocker 221 back and forth to drive the first motor 217 to run. The first motor 217 drives the upper arm 216 to swing left and right. The upper arm 216 drives the rotating frame 213 to rotate up and down through the lower arm 214. The upper arm 216 and the lower arm 214 realize the up and down rotation of the rotating frame 213. The left and right push and pull rods drive the second motor 218 to run. The second motor 218 drives the rotating frame 212 to make the rotating frame 213 rotate.

[0040] Finally, the pump at the bottom of the inner cavity of the medicine tank 11 pumps the liquid into the nozzle 13 through the connecting pipe 12 and sprays it out.
