Detailed implementation mode

[0022] An embodiment of the utility model provides an inflatable burn wound debridement device, as Figures 1-4 shown, which includes a telescopic bracket 1 and an airbag groove 2 arranged on the telescopic bracket 1. The airbag groove 2 is closed at one end and open at the other end, similar to the shape of the existing debridement groove, and is made of sterile rubber or silica gel. A U-shaped support 3 is arranged at the open end of the airbag groove 2. The U-shaped support 3 and the airbag groove 2 are an integral airbag. The U-shaped support 3 is used to support the patient's limb. A drain port 5 is arranged at the bottom of the end of the airbag groove 2 far from the U-shaped support 3. The drain port 5 is externally connected through a drainage tube 6 for draining during debridement. An inflation port 4 for inflation is also arranged on the side of the airbag groove 2, and the airbag groove 2 is inflated and deflated through the inflation port 4.

[0023] The bottom of the airbag groove 2 is flat. The airbag groove 2 itself has a certain supporting ability and can also be placed on other platforms for cleaning operations away from the telescopic bracket 1.

[0024] As Figures 2-4 shown, the telescopic bracket 1 includes a base 11, a top seat 12, several groups of cross-hinged link members 13, a fixed support rod 14, and several movable support rods 15. The top seat 12 is arranged on the base 11. The base 11 is used for support, and the cross-hinged link members 13 are arranged on the top seat 12.

[0025] As Figure 3 shown, a total of five groups of cross-hinged link members 13 are arranged in this embodiment. Among them, the three groups of cross-hinged link members 13 in the center are formed by two links cross-hinged, and the cross-hinged link members 13 on the other two sides are composed of two links with half the length of the three groups of cross-hinged link members 13 in the middle, and are hinged at the head and tail. The two ends of adjacent two groups of cross-hinged link members 13 are hinged to each other. The hinge shaft of the cross-hinged link members 13 at the center is fixed on the top seat 12. The fixed support rod 14 is fixed on the hinge shaft of the cross-hinged link members 13 at the center. There are four movable support rods 15 in total. A movable support rod 15 is arranged on the hinge shaft of each cross-hinged link member 13 on both sides. One fixed support rod 14 and four movable support rods 15 are arranged in the way as Figure 3 shown. When the fixed support rod 14 and the movable support rods 15 are fully extended, they correspond to the bottom of the airbag groove 2. The bottom of the airbag groove 2 is detachably connected to the fixed support rod 14 and several movable support rods 15.

[0026] By setting the telescopic bracket 1, when the airbag groove 2 is not in use, the cross-hinged link members 13 of the telescopic bracket 1 drive the airbag groove 2 to fold together from both sides towards the top seat 12. When in use, the cross-hinged link members 13 are synchronously unfolded as the airbag groove 2 is inflated. When the airbag groove 2 needs to be cleaned after use, it can be deflated and removed, and can be folded, which is not only convenient to carry, but also light in weight and convenient to clean.

[0027] As shown Figures 3-4 in the figure, the telescopic support 1 further includes two sets of axial guiding components, which are respectively arranged on both sides of the top seat 12. Each set of axial guiding components includes a first fixing block 16, a second fixing block 17, a first sliding groove 18, and a second sliding groove 19. The second sliding groove 19 is wrapped outside the first sliding groove 18 and can slide along the length direction of the first sliding groove 18. The first fixing block 16 and the second fixing block 17 are sequentially arranged from the center to the outside at the bottom end of the hinge shaft connecting the movable support rod 15. Since the upper and lower ends of the hinge shaft are fixed on the movable support rod 15 and the fixing block, the shape of the movable support rod 15 remains unchanged during the movement. The first fixing block 16 and the second fixing block 17 are respectively connected to the first sliding groove 18 and the second sliding groove 19. Specifically, the first fixing block 16 can be fixed at the outer end of the first sliding groove 18 or slidably fitted inside the first sliding groove 18; the second fixing block 18 is fixed at the outer end of the second sliding groove 19.

[0028] A receiving cavity 20 is horizontally opened on the top seat 12 for the second sliding groove 19 to slide into. The cross-sectional area of the receiving cavity 20 is larger than that of the second sliding groove 19.

[0029] As shown Figure 3 in the figure, when the cross-hinged link member 13 is fully extended, the inner end of the first sliding groove 18 is inside the receiving cavity 20, and the leading end of the second sliding groove 19 still sleeves outside the first sliding groove 18. As shown Figure 4 in the figure, when the cross-hinged link member 13 is fully retracted, the first sliding groove 18 moves inside the receiving cavity 20, and the second sliding groove 19 slides along the outside of the first sliding groove 18 and most of it can be received inside the receiving cavity 20.

[0030] As shown Figures 2-3 in the figure, hooks 8 are provided on both sides of the top of the fixed support rod 14 and several movable support rods 15, and fixing rings 7 corresponding to the hooks 8 are provided at the bottom of the airbag groove 2. During use, the fixing rings 7 at the bottom of the airbag groove 2 are sleeved on the corresponding hooks 8 one by one, that is, as shown Figure 2 in the figure, to prevent the airbag groove 2 from slipping off the support during use and improve the stability of the airbag groove 2 during use.

[0031] To avoid falling off, the hook 8 is in an inverted shape, similar to a faucet shape, and the end of the hook 8 is rotatably connected to the fixed support rod 14 or the movable support rod 15. When the fixing ring 7 is sleeved on the hook 8, the hook 8 can be rotated inward, which can effectively prevent the fixing ring 7 from falling off the hook 8.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
