Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an intelligent wound debridement and medicine spraying integrated device. Background Art

[0002] General surgery debridement devices are essential tools in general surgery and play a key role in wound management. Designed specifically for cleaning and pre-treating various wounds, they efficiently and precisely remove dirt, foreign matter, and necrotic tissue from the wound surface, creating a clean, healthy environment for wound healing. By thoroughly debridement, these devices significantly reduce the risk of wound infection and avoid delayed healing or complications caused by infection. Furthermore, the debridement process stimulates blood circulation around the wound and activates the body's self-repair mechanisms, accelerating wound healing and helping patients recover faster and alleviate pain.

[0003] In the use process of existing general surgery debridement devices, the patient's limbs are usually placed on a support mechanism, and then the medical staff uses a handheld flushing gun to clean the wound. However, during this process, the flushing water directly stimulates the sensitive nerve endings on the surface of the wound, and the patient often feels severe pain, which may cause the limbs to move unconsciously. This limb reaction not only makes the cleaning operation difficult to carry out stably, increasing the difficulty of the medical staff's operation, but also may make the debridement incomplete due to unstable operation, and even cause secondary contamination and infection of the wound. This will seriously affect the overall effect of debridement and is not conducive to the subsequent healing of the patient's wound. Summary of the Invention

[0035] In one embodiment, for the above-mentioned workbench 1, a first sliding groove 11 is opened on the top of the workbench 1, and two first sliding grooves 11 are provided. A second threaded rod 12 is rotatably installed inside the two first sliding grooves 11, and the second threaded rod 12 is threadedly connected to the movable frame 3. The thread rotation directions of the second threaded rod 12 are opposite to realize the synchronous movement of the movable frame 3.

[0036] In one embodiment, for the above-mentioned second threaded rods 12, the two second threaded rods 12 are fixedly mounted with a first transmission wheel 13, and the two first transmission wheels 13 are connected through a first transmission belt 14.

[0045] The working principle of the intelligent wound debridement and drug spraying device proposed by the present invention is as follows: when treating a wound, after the electric base 18 moves to a suitable position above the wound, the control valve on the connecting pipe 25 connected to the disinfection box 26 is activated. The disinfectant in the disinfection box 26 is transported through the connecting pipe 25 made of medical-grade silicone material to the atomizing spray head 23 inside the applicator sleeve 22. The atomizing spray head 23 atomizes the disinfectant and sprays it on the wound to disinfect it. After disinfection is completed, the control valve on the connecting pipe 25 connected to the disinfection box 26 is closed, and the control valve on the connecting pipe 25 connected to the clean water tank 27 is opened. The clean water in the clean water tank 27 is transported through the connecting pipe 25 to the atomizing spray head 24 inside the applicator sleeve 22. The atomizing spray head 24 atomizes the clean water and sprays it on the wound to rinse the wound.

[0046] Wastewater generated during the flushing process flows into a wastewater tank 28 provided on the workbench 1. The wastewater is then filtered through a removable, cleanable stainless steel filter 29 to remove impurities. The filtered wastewater then flows into a wastewater tank 30 fixed to the bottom of the workbench 1 for collection. When a certain number of wounds have been treated or when wastewater tank 30 is nearly full, it can be cleaned. The filter 29 can also be removed and cleaned, depending on usage, to ensure effective filtration.

One of the worms 35 is fixedly installed with a third motor 38, and the third motor 38 is a reduction motor to provide sufficient torque.

[0050] The working principle of the intelligent wound debridement and drug spraying integrated device proposed in the present invention is that when the height of the workbench 1 needs to be adjusted, the third motor 38 is started. The third motor 38 is a reduction motor that can provide sufficient torque. The third motor 38 drives one of the worms 35 fixedly connected to it to rotate. The third transmission wheel 36 on the worm 35 drives the third transmission wheel 36 on the other worm 35 to rotate through the third transmission belt 37, so that the two worms 35 rotate synchronously.
