[0032] A pressing tube 3 is inserted into the interior of the shell 1. The interior of the pressing tube 3 is hollow. A pressing cap 31 is connected to the end of the pressing tube 3 away from the protective cap 2. A first spring 33 is arranged between the pressing cap 31 and the upper guide tube 4. A filling port 311 is provided on the surface of the pressing cap 31. The filling port 311 is communicated with the interior of the pressing tube 3. A pressing pump 32 is installed at one end of the pressing tube 3. The pressing pump 32 is located at the end of the pressing tube 3 close to the protective cap 2. A spray nozzle 321 is arranged on the surface of the pressing pump 32. A rotating tube 8 is rotatably installed on the surface of the pressing tube 3. The rotating tube 8 is arranged between the pressing tube 3 and the upper guide tube 4. A guide column 81 and a pressure plate 82 are fixedly installed on the surface of the rotating tube 8. The guide column 81 is slidably arranged inside the telescopic slot 41. The pressure plate 82 is located at the end of the lower guide tube 5 away from the upper guide tube 4.

[0033] A telescopic rod 7, wherein the telescopic rod 7 is slidably inserted into the interior of the telescopic bracket 6, and three groups of telescopic rods 7 are provided. A sliding cap 71 is installed at one end of the telescopic rod 7, and the sliding cap 71 is arranged at one end of the telescopic rod 7 close to the pressure plate 82. The sliding cap 71 slides and fits with the pressure plate 82. A retaining ring 72 is fixedly installed on the surface of the telescopic rod 7, and a second spring 73 is provided between the retaining ring 72 and the telescopic bracket 6. The ends of the three groups of telescopic rods 7 are respectively installed with a liquid absorption tool 9, a medicine applicator tool 10 and a cleaning tool 101.

[0034] The exudate absorption tool 9 described in the present invention can be a negative pressure absorption ball, the applicator tool 10 can be an applicator plate, and the cleaning tool 101 can be a cleaning brush, a scraper, etc. The above tool types are only partially listed and belong to the prior art. The tools used in the wound treatment device include but are not limited to the above-mentioned types.

[0035] The present invention provides a switchable wound treatment device. When in use, the protective cap 2 is removed from the end of the housing 1, and then the exudate absorption tool 9, the applicator tool 10, and the cleaning tool 101 are installed to the ends of the three sets of telescopic rods 7 in a certain order as needed, and then the protective cap 2 is installed to the end of the housing 1 to cover the exudate absorption tool 9, the applicator tool 10, and the cleaning tool 101, and then the disinfectant is filled into the inside of the pressing tube 3 through the filling port 311;

[0036] By pressing the pressing cap 31, the pressing tube 3 is driven to move, so that the guide column 81 enters the first lower V-shaped groove 51 from the inside of the telescopic groove 41, and at the same time, the pressing plate 82 presses a group of telescopic rods 7 downward through the sliding cap 71, so that the cleaning tool 101 passes through the absorbent cotton 23 and extends from the end of the protective cap 2. At the same time, the pressing pump 32 abuts against the fixed pressure column 24, so that the disinfectant inside the pressing tube 3 is sprayed out from the spray nozzle 321 to disinfect the tools inside the protective cap 2. At this time, the absorbent cotton 23 absorbs the spilled disinfectant, and the pressing on the pressing cap 31 is released. Under the action of the rebound force of the first spring 33, the guide column 81 enters the inside of the upper V-shaped groove 42, and fixes the cleaning tool 101 on the outside of the protective cap 2, thereby facilitating the cleaning of the patient's wound. After cleaning, the pressing cap 31 is pressed to make the guide column 81 pass through the second lower V-shaped groove 52 and enter the inside of the next group of telescopic grooves 41, and the cleaning tool 101 is received into the inside of the protective cap 2.

[0037] According to the above steps, the pressing cap 31 is pressed continuously to extend the cleaning tool 101, the exudate absorption tool 9, and the applicator tool 10 in sequence, thereby realizing one-handed switching of different wound treatment tools, which is convenient for single-person operation, reduces the difficulty of wound treatment operation, and improves the efficiency of wound treatment.

[0038] While pressing the pressing cap 31, the constant pressure column 24 squeezes the pressing pump 32, so that the disinfectant inside the pressing tube 3 is sprayed out through the spray nozzle 321 to disinfect the tools inside the protective cap 2, thereby facilitating the disinfection of the tools when operated by one person.

[0039] As a further improvement of the present invention, an anti-mistaken entry slope 521 is provided on the side of the second lower V-shaped groove 52 close to the telescopic groove 41, so that the guide column 81 can be guided when passing through the exit of the second lower V-shaped groove 52, thereby effectively preventing the guide column 81 from mistakenly entering the interior of the second lower V-shaped groove 52.

[0040] As a further improvement of the present invention, on the basis of the above, by providing multiple groups of telescopic rods 7, different tools are installed at the ends of the multiple groups of telescopic rods 7 as needed, so that the treatment tool can adapt to the treatment of more wounds.

[0041] Working principle: When the present invention is in use, the protective cap 2 is removed from the end of the shell 1, and then the exudate absorption tool 9, the applicator tool 10, and the cleaning tool 101 are installed to the ends of the three groups of telescopic rods 7 in a certain order as needed, and then the protective cap 2 is installed to the end of the shell 1 to cover the exudate absorption tool 9, the applicator tool 10, and the cleaning tool 101, and then the disinfectant is filled into the interior of the pressing tube 3 through the filling port 311, and the pressing cap 31 is pressed to drive the pressing tube 3 to move, so that the guide column 81 enters the interior of the first lower V-shaped groove 51 from the interior of the telescopic groove 41, and at the same time, the pressing plate 82 presses down a group of telescopic rods 7 through the sliding cap 71, so that the cleaning tool 101 passes through the absorbent cotton 23 and extends out from the end of the protective cap 2, and at the same time, the pressing pump 32 abuts against the constant pressure column 24, so that the disinfectant in the pressing tube 3 is sprayed from the spray nozzle 32. 1 is sprayed out to disinfect the tools inside the protective cap 2. At this time, the absorbent cotton 23 absorbs the spilled disinfectant, and the pressing of the pressing cap 31 is released. Under the action of the rebound force of the first spring 33, the guide column 81 enters the interior of the upper V-shaped groove 42, and the cleaning tool 101 is fixed to the outside of the protective cap 2, so as to facilitate cleaning of the patient's wound. After cleaning, the pressing cap 31 is pressed to make the guide column 81 pass through the second lower V-shaped groove 52 and enter the interior of the next group of telescopic grooves 41, and the cleaning tool 101 is received in the interior of the protective cap 2. According to the above steps, the pressing cap 31 is continuously pressed to make the cleaning tool 101, the exudate absorption tool 9, and the applicator tool 10 extend in sequence, so as to realize the single-handed switching of different wound treatment tools, which is convenient for single-person operation, reduces the difficulty of wound treatment, and improves the efficiency of wound treatment.
