Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a dressing component used for a lumbar cistern drainage tube. Background Art

[0002] Lumbar catheter drainage is to place a drainage tube from L3 or L4 into the lumbar cistern, so as to achieve continuous drainage and avoid repeated lumbar punctures. This operation has the advantages of less trauma, controllable drainage speed, and avoidance of the pain of repeated lumbar punctures. Continuous lumbar drainage can not only drain cerebrospinal fluid and reduce intracranial pressure, but also inject drugs into the subarachnoid space through the drainage tube.

[0003] Since the external drainage tube is long and thin, there is currently no special dressing for external fixation of this tube in clinical practice. Most of them are fixed with transparent infusion patches, elastic tape and other dressings. If the fixation is not appropriate, the tube is easily broken due to pulling; and because of the long retention time, the skin is under long-term pressure and is prone to medical device-related skin pressure injury. In addition, the main risk of lumbar drainage is retrograde infection, and cerebrospinal fluid overflow and skin infection at the puncture site are also prone to occur. How to prevent infection is also a point that needs improvement. Utility Model Content

[0025] The utility model is described in detail below in conjunction with the accompanying drawings.

[0026] As attached Figure 1 To Attachment Figure 7 As shown, Specific embodiment:

[0028] like Figure 1-3 As shown, a dressing assembly for lumbar drainage tube includes a puncture point fixing dressing 1, a catheter fixing dressing 2 and a tube orifice fixing dressing 3. The puncture point fixing dressing 1 includes a transparent adhesive sheet 1-1, and the adhesive sheet 1-1 is specifically made of transparent silicone material, so that the puncture point can be observed through the adhesive sheet 1-1; an antibacterial dressing 1-2 is provided in the middle of the back of the adhesive sheet 1-1, such as chlorhexidine glucose, which can absorb exudate and prevent skin infection and retrograde infection at the puncture point. A first adhesive layer 1-3 is provided around the back of the adhesive sheet 1-1, and a first release paper is also provided on the back of the adhesive sheet 1-1, and the first release paper is covered on the first adhesive layer 1-3 and covers the entire antibacterial dressing 1-2; the catheter fixing dressing 2 includes an L-shaped adhesive strip 2-1, and the material of the adhesive strip 2-1 is one of silicone, hydrogel, and foam dressing. The adhesive strip 2-1 is composed of a U-shaped fixed slot 2-11 and two adhesive parts 2-12. The internal space of the U-shaped fixed slot 2-11 can accommodate the drainage tube. The two adhesive parts 2-12 are located on both sides of the fixed slot 2-11. A second adhesive layer is provided inside the fixed slot 2-11 and at the bottom of the adhesive part 2-12. A second release paper is also provided on the second adhesive layer. The tube mouth fixing dressing 3 includes a fixing sheet 3-1. The material of the fixing sheet 3-1 is one of silicone, hydrogel, and foam dressing. A third adhesive layer is provided on the back of the fixing sheet 3-1. A third release paper is provided on the third adhesive layer. A drainage tube fixing component 4 is provided on the front of the fixing sheet 3-1.

[0029] Specific method of use: After the lumbar drainage tube is successfully punctured and placed, first remove the first release paper on the back of the puncture point fixing dressing 1, and align the antibacterial dressing 1-2 with the puncture point for fixing; then remove the second release paper in the U-shaped catheter fixing slot 2-11 in the middle of the catheter fixing dressing 2, and fix the drainage tube therein. Since the second adhesive layer can adhere to the drainage tube, it avoids direct contact of the drainage tube with the skin to cause medical device-related skin pressure damage. Remove the second release paper on the adhesion parts 2-1 on both sides, and fix the drainage tube to the shoulder through the patient's waist; finally, the first connection port of the lumbar drainage tube is externally fixed to the drainage tube fixing component 4 of the tube port fixing dressing 3, and then remove the third release paper and stick it to the appropriate skin on the patient's shoulder. Fix the first connection port of the drainage tube to prevent the line from being pulled and caused by breakage. It should be noted that the puncture point fixing dressing 1, the catheter fixing dressing 2 and the tube orifice fixing dressing 3 are three separate structures, which are combined only when used. The separation of the puncture point fixing dressing 1 and the catheter fixing dressing 2 is convenient for dressing change operation.

[0030] In addition, the drainage tube fixing assembly 4 can be designed into different structures according to needs, and two different structural designs are provided below.

[0031] like Figure 4 As shown, as one of the structures of the utility model, the drainage tube fixing assembly 4 includes a Velcro fleece surface 5 arranged on the front of the fixing plate 3-1, and the front of the fixing plate 3-1 is fixed with a first fixing strip 6 and a second fixing strip 7, the first fixing strip 6 is provided with a through hole 8, the second fixing strip 7 can pass through the through hole 8, and the first fixing strip 6 and the second fixing strip 7 are both provided with Velcro hooks. This structure uses the first fixing strip 6 and the second fixing strip 7 arranged crosswise to fix the drainage tube in the middle, and the structure is simple, but the fixing strength is relatively low.

[0032] like Figure 5-7 As shown, as another structure of the utility model, the drainage tube fixing assembly 4 includes a first sleeve 9 arranged on the fixing plate 3-1, a second sleeve 10 is threadedly connected to the first sleeve 9, and the sides of the first sleeve 9 and the second sleeve 10 are provided with a through groove 11 that penetrates from front to back, and the drainage tube can enter the first sleeve 9 and the second sleeve 10 from the through groove 11, and an elastic clamp is also provided inside the second sleeve 10, and the elastic clamp includes a fixing ring 12 and a plurality of elastic clamping teeth 13, and the fixing ring 12 is composed of two semi-ring bodies 14, and the clamping teeth 13 are arranged on the side of the semi-ring body 14 away from the first sleeve 9, and a conical extrusion groove 15 corresponding to the clamping teeth 13 is provided inside the second sleeve 10, and a guide block 16 is provided on the semi-ring body 14, and the guide block 16 is slidably connected to the guide groove on the inner wall of the second sleeve 10. The width of the elastic clamping teeth 13 is greater than the width of the through groove 11, so as to prevent the clamping teeth 13 from passing through the through groove 11.

[0033] When fixing the structure, it is necessary to first unscrew the second sleeve 10 from the first sleeve 9, take out the elastic clip inside, insert the drainage tube into the inside through the side grooves 11 of the first sleeve 9 and the second sleeve 10, and then put the two semi-ring bodies 14 into the second sleeve 10 after engaging them from both sides of the drainage tube, and tighten the first sleeve 9 and the second sleeve 10. At this time, the fixing ring 12 is squeezed, and the elastic clip 13 approaches the extrusion groove 15 side, and the extrusion groove 15 forces the elastic clip 13 to shrink toward the middle, thereby fixing the drainage tube. The structure can adjust the fixing force of the drainage tube by tightening the first sleeve 9 and the second sleeve 10. It has high strength, and the drainage tube can be inserted from the side without finding the end of the drainage tube and then performing the tube insertion operation, which is more convenient.

[0034] Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
