[0001] The present invention relates to the technical field of medical appliances, and in particular to a burn care dressing change device and method with a sterile disinfection structure. Background Art

[0002] Burns generally refer to tissue damage caused by heat, including hot liquids (such as water, soup, oil, etc.), steam, high-temperature gases, flames, molten or solid hot metals (such as molten steel, steel ingots), and strong radioactive radiation, mainly referring to the skin and / or mucous membranes. In severe cases, it can also damage the subcutaneous or / and submucosal tissues, such as muscles, bones, joints, and even internal organs. Scalds are tissue injuries caused by hot liquids, steam, etc., and are a type of thermal burn. The degree of burns varies depending on the temperature and the duration of action, and the local changes can be divided into four degrees.

[0003] In the prior art, due to the lack of a convenient positioning function in general care dressing change devices, after placing the injured limb of the patient into the device, if the burned area is large or the angle is inconvenient, it is necessary to repeatedly adjust the limb position, which not only affects work efficiency but also easily causes secondary damage to the burned area. Summary of the Invention

[0004] The present invention discloses a burn care dressing change device and method with a sterile disinfection structure, aiming to solve the technical problem in the background art that general care dressing change devices lack a convenient positioning function. If the burned area is large or the angle is inconvenient, it is necessary to repeatedly adjust the limb position, resulting in inconvenient use.

[0005] A burn care dressing change device with a sterile disinfection structure proposed by the present invention includes a main box body. Two symmetrically arranged mounting bases are fixedly connected to the inner wall of the main box body. A same sealing and stabilizing module is provided on the main box body and the two mounting bases. A positioning and medicine application module is arranged inside the main box body. The sealing and stabilizing module includes two sealing air bags, and both of the two sealing air bags are fixedly connected to the inner wall of the corresponding mounting base. The positioning and medicine application module includes a plurality of limiting rods. Both ends of the plurality of limiting rods are fixedly connected to the outer wall of the corresponding mounting base. A same sliding frame is slidably connected to the outside of the plurality of limiting rods. A rotating ring frame is movably connected to the inner wall of the sliding frame. A water-air dual-purpose pump and a liquid storage tank are fixedly connected to the top of the main box body. An outlet pipe is arranged on the top of the water-air dual-purpose pump, and one end of the outlet pipe away from the water-air dual-purpose pump is fixedly connected to the liquid storage tank.

[0006] In a preferred solution, two symmetrically arranged fixing rods are fixedly connected to the rotating ring frame. Connecting bins are fixedly connected to the outside of both of the two fixing rods. Spray heads are fixedly connected to one side of the two connecting bins facing each other. Injection pumps are fixedly connected to one side of the two connecting bins away from the spray heads.

[0007] In a preferred embodiment, one side of the rotating ring frame is fixedly connected with a two-way valve. Both output ends of the two-way valve are fixedly connected with arc-shaped pipes. One end of each of the two arc-shaped pipes away from the two-way valve is fixedly connected to the corresponding injection pump. And a toothed ring is fixedly connected to the outside of the rotating ring frame. A circular hole is formed in the sliding frame, and a universal motor is fixedly connected in the circular hole. The output end of the universal motor is fixedly connected with a rotating gear, and the rotating gear meshes with the toothed ring.

[0008] In a preferred embodiment, one outer wall of the main box body is fixedly connected with a medicine placing box and a delivery pump. The input end of the delivery pump is fixedly connected to the medicine placing box, and the output end of the delivery pump is fixedly connected with a delivery pipe. One end of the delivery pipe away from the delivery pump is fixedly connected to the input end of the two-way valve.

[0009] In a preferred embodiment, a guide rail member is fixedly connected to the bottom inner wall of the main box body. A rack is fixedly connected to one inner wall of the guide rail member. And a driving motor is fixedly connected to the bottom of the sliding frame. The output end of the driving motor is fixedly connected with a transmission gear, and the transmission gear meshes with the rack.

[0010] By providing a positioning medicine application module, the burn position is observed and confirmed through an imaging probe. The sliding frame is driven to slide by the driving motor. At the same time, according to the distance between the medicine spraying head and the burn, the rotating ring frame is rotated in a suitable direction by the universal motor. After driving the medicine spraying head to the designated position, the delivery pump is started to pump the liquid medicine into the two-way valve. The output end of the two-way valve close to the burn side is opened, and the liquid medicine is sprayed onto the burn position through the injection pump. The burn area can be observed and positioned, and then the liquid medicine spraying is guided. There is no need to repeatedly adjust the limb position, which simplifies the medicine application process and reduces the pain of the patient and the burden of medical operation.

[0011] In a preferred embodiment, an air pump and a connection valve seat are fixedly connected to one side of the main box body. The output end of the air pump is fixedly connected with an air delivery pipe, and one end of the air delivery pipe away from the air pump is fixedly connected to the input end of the connection valve seat.

[0014] In a preferred embodiment, an air inlet pipe is arranged on the top of the water-air dual-use pump, and an electromagnetic valve I and an electromagnetic valve II are respectively arranged on the liquid outlet pipe and the air inlet pipe.

[0015] By setting up a sealing and stabilizing module, the intake air volume of the sealing airbag is controlled by the control valves on both sides of the switch, enabling the sealing airbags on both sides to fully conform to the patient's limb. This not only increases the placement stability and comfort but also keeps the interior of the main box sealed. By setting up a water-air dual-purpose pump, a shunt pipe, a nozzle, a liquid storage tank, and an air inlet pipe, the disinfectant liquid is pumped into the shunt pipe by the water-air dual-purpose pump and sprayed out through the nozzle to sterilize and disinfect the interior of the main box, maintaining a sterile environment at the wound site. At the same time, humid air is sent in through the air inlet pipe to control the oxygen content and humidity inside the main box, creating a suitable environment conducive to the recovery of burns. With the cooperation of the seal, the burn position can always be kept in a suitable environment, avoiding the need for the patient's limb to enter and exit the nursing and dressing change device multiple times, maximizing the maintenance of the sterile environment, and reducing the risk of infection.

[0016] A burn care and dressing change method with a sterile disinfection structure, using a burn care and dressing change device with a sterile disinfection structure as described above, includes the following steps:

[0017] Step 1: Place the patient's burned limb into the main box, start the air pump to pump air into the connecting valve seat through the air delivery pipe, and control the intake air volume of the sealing airbag through the control valves on both sides of the switch, enabling the sealing airbags on both sides to fully conform to the patient's limb. This not only increases the placement stability and comfort but also keeps the interior of the main box sealed.

[0018] Step 2: After sealing, close solenoid valve 2, open solenoid valve 1, start the water-air dual-purpose pump to pump the disinfectant liquid into the shunt pipe and spray it out through the nozzle to sterilize and disinfect the interior of the main box. After completion, close solenoid valve 1, open solenoid valve 2, and send in humid air through the air inlet pipe to control the oxygen content and humidity inside the main box.

[0019] Step 3: Observe and confirm the burn position through the imaging probe, start the drive motor to drive the sliding frame to slide. At the same time, according to the distance between the medicine spraying head and the burn, start the universal motor to rotate the rotating ring frame in the appropriate direction, drive the medicine spraying head to the designated position, then start the delivery pump to pump the medicine liquid to the two-way valve, open the output end of the two-way valve close to the burn side, and the medicine liquid is sprayed onto the burn position through the injection pump.

[0020] As can be seen from the above, a burn care and dressing change device with a sterile disinfection structure provided by the present invention can observe and locate the burn area through the positioning and medicine application module, and then guide the spraying of the medicine liquid, eliminating the need to repeatedly adjust the limb position, simplifying the medicine application process, reducing the pain of the patient and the burden of medical operations. At the same time, it can keep the burn position in a suitable environment all the time, avoiding the need for the patient's limb to enter and exit the nursing and dressing change device multiple times, maximizing the maintenance of the sterile environment, and reducing the risk of infection.
