[0022] As attached Figure 1 To Attachment Figure 6 ,

[0023] Embodiment 1:

[0024] The wet heat disinfection device for instrument care in a ICU comprises a disinfection box 1, an instrument conveying mechanism and a disinfectant spraying mechanism. The instrument conveying mechanism comprises a turntable 3 rotatably installed inside the disinfection box 1, a plurality of instrument clamping members are distributed in a ring array on the top of the turntable 3, and the turntable 3 is connected to a first driving mechanism; the disinfectant spraying mechanism comprises a liquid storage tank 2, a disinfection tank 5 and an atomizing nozzle 9, the liquid storage tank 2 is arranged above the turntable 3, the atomizing nozzle 9 is installed at the bottom of the liquid storage tank 2, and is used to spray disinfectant to an instrument clamped by one of the instrument clamping members, a piston 6 is provided in a sliding arrangement in the disinfection tank 5, a push-pull rod 7 is fixedly connected to the top of the piston 6, and one end of the push-pull rod 7 extending from the top of the disinfection tank 5 is connected to the second driving mechanism, a conduit 10 is provided at the bottom of the disinfection tank 5 to communicate with the liquid storage tank 2, a heating component is provided in the liquid storage tank 2, and a check valve is provided on the conduit 10.

[0025] When the wet heat disinfection device for instrument care in the intensive care unit of this embodiment is working, the heating component in the liquid storage tank 2 heats the disinfectant stored therein, and the second driving mechanism pulls the push-pull rod 7 to draw the heated disinfectant in the liquid storage tank 2 upward, and stops drawing after drawing an appropriate amount of disinfectant. The second driving mechanism pushes the push-pull rod 7 downward, and since a check valve is provided, the disinfectant cannot flow back to the liquid storage tank 2, so that the disinfectant is sprayed through the atomizing nozzle 9 to spray the disinfectant on the instrument clamped by one of the instrument clamps. After spraying for a period of time, the turntable is driven to rotate by the first driving mechanism, so that the next instrument to be disinfected is rotated to the bottom of the atomizing nozzle 9 for cyclic operation.

[0026] Embodiment 2:

[0027] The second driving mechanism includes a limit plate 14 fixedly connected to the push-pull rod 7, the limit plate 14 is fixedly connected to the guide rod 13, the guide rod 13 is slidably connected to a vertical first slide groove, the first slide groove is arranged on the liquid storage tank 2, the limit plate 14 is provided with a horizontal second slide groove, a boss 15 is slidably connected in the second slide groove, the boss 15 is fixedly connected to the driving plate 11, the driving plate 11 is fixedly connected to the driving shaft 12, the boss 15 deviates from the center of the driving shaft 12, and the driving shaft 12 is rotatably connected to the liquid storage tank 2.

[0028] When the drive shaft 12 is rotated, the drive shaft 12 drives the drive plate 11 and the boss 15 to rotate synchronously. Since the boss 15 is limited in the horizontal second slide groove, the boss 15 drives the limit plate 14 to reciprocate when it rotates, and then drives the piston 6 to reciprocate through the push-pull rod 7 to achieve cyclic absorption and spraying of disinfectant. The drive shaft of the device can be driven manually or by a motor. Preferably, the drive shaft 12 is fixedly connected to the active end of the drive motor, and the drive motor is connected to the control unit.

[0032] In order to prevent the half gear 22 from disengaging from the full gear and causing the full gear to continue rotating due to the relationship and fail to mesh normally next time, the fourth transmission shaft is rotatably connected to the disinfection box 1 through a damping ring made of rubber material.

[0033] Embodiment 4:

[0034] The tool clamping member includes a support shaft 4, a first clamping plate 23 and a second clamping plate 24. The first clamping plate 23 and the second clamping plate 24 are located in the same plane and are elastically hinged on the support shaft 4 in an X shape.
