Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a sterile drainage strip for a preauricular fistula wound. Background Technology

[0002] Preauricular fistula is a common congenital ear malformation. The fistula is a narrow tube that can extend deep into the auricular cartilage. One end opens into the upper front part of the auricle, and the other end is usually blind. When infection occurs in the fistula, symptoms such as redness, swelling, pain, itching, and purulent discharge will appear. In order to fully drain the pus and promote wound healing, a drainage strip is needed to drain the pus. The current method for draining a preauricular fistula wound is to disinfect the wound, use tweezers to pick up a sterile gauze, and then insert the sterile gauze into the wound, leaving the end of the sterile gauze outside the wound. The existing technology has the following problems: When using sterile gauze for drainage, although the porous structure of sterile gauze can absorb exudate, the drainage effect is limited, and the absorption capacity of sterile gauze is limited. After the absorption is saturated, it needs to be replaced frequently. Frequent replacement of sterile gauze may damage the newly formed tissue and prolong the recovery time. Therefore, we propose a sterile drainage strip for preauricular fistula wounds. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-7 This embodiment provides a technical solution: a sterile drainage strip for a preauricular fistula wound, including an ear loop 1, a fixing seat 2 at the left end of the front side of the ear loop 1, a drainage material 3, and a fixing mechanism 5. The fixing mechanism 5 includes a sliding hole 51, a sliding column 52, and an arc-shaped clamp 53. The sliding hole 51 is opened on the left side of the outer surface of the fixing seat 2. The sliding column 52 is slidably connected inside the sliding hole 51. The arc-shaped clamp 53 is provided at the right end of the sliding column 52 and is located inside the mounting hole 4. The fixing mechanism 5 also includes a pull block 54, a limiting ring 55, and a spring 56. The pull block 54 is provided at the left end of the sliding column 52. The limiting ring 55 is fixedly sleeved on the outer surface of the sliding column 52. The spring 56 is movably sleeved on the outer surface of the sliding column 52 and is located on the inner wall of the sliding hole 51 and the limiting ring 55. Between the left side of the ring 55, the inner arc surface of the arc-shaped clamp 53 and the right side of the inner wall of the mounting hole 4 are both provided with rubber pads 7. The rubber pads 7 are all semi-circular arc-shaped. The upper end of the outer surface of the ear 1 is fixedly connected with a hook 6. The hook 6 is a ring with an opening at the lower rear end. After the staff disinfects the wound, they hang the fixing seat 2 on the patient's ear through the hook 6 and the ear 1. Then they pull the pull block 54. The pull block 54 drives the sliding column 52 to move to the left along the sliding hole 51. The sliding column 52 drives the rubber pad 7 on the left side to move through the arc-shaped clamp 53. At this time, the limiting ring 55 squeezes the spring 56. When the appropriate depth is inserted, the pull block 54 is released. The rebound force of the spring 56 drives the arc-shaped clamp 53 to move to the right through the limiting ring 55 and the sliding column 52 until the rubber pads 7 on both sides fix the cylindrical strip 31. Drainage material 3: It includes a cylindrical strip 31, a drainage channel 32, drainage holes 33, a guide groove 34, and sterile gauze 35 (the cylindrical strip 31 is a silicone cylindrical strip). The front side of the fixing base 2 has an installation hole 4, and the cylindrical strip 31 is installed inside the installation hole 4. The rear end of the cylindrical strip 31 is hemispherical. A drainage channel 32 is opened inside the cylindrical strip 31. The rear end of the outer surface of the cylindrical strip 31 has evenly distributed drainage holes 33, each connected to a drainage channel 32. The rear end of the outer surface of the cylindrical strip 31 has evenly distributed guide grooves 34, which connect adjacent drainage holes 33. A sterile gauze 35 is fixedly fitted onto the rear end of the outer surface of the cylindrical strip 31. The drainage holes 33 can be divided into multiple groups of adjacent holes (too few drainage holes 33 will result in poor drainage, while too many drainage holes 33 will cause blockage of pus, leading to delayed pus drainage; to ensure drainage effectiveness, the number of drainage holes 33 should be increased to a certain extent). (Minimum 3 groups, maximum 6 groups). Each group of drainage holes 33 is distributed circumferentially at equal angles around the central axis of the cylindrical strip 31. The drainage material 3 also includes protrusions 36 and scale lines 37. The outer surface of the cylindrical strip 31 has protrusions 36 at the front end and scale lines 37 in the middle of the outer surface of the cylindrical strip 31. Then, one end of the cylindrical strip 31 wrapped with sterile gauze 35 is inserted into the wound through the installation hole 4. The insertion depth is observed through the scale lines 37. The pus in the wound passes through the sterile gauze. The gauze 35 flows into the drainage hole 33 through the guide groove 34, and then into the drainage channel 32 through the drainage hole 33. The drainage holes 33 are all distributed in a circumferential angle around the central axis of the cylindrical strip 31, which effectively improves the drainage effect and has a large absorption capacity, so it does not need to be replaced frequently. When replacement is needed, pull the pull block 54 to release the fixing relationship between the fixing seat 2 and the cylindrical strip 31, and then lift the protrusion 36 to remove the cylindrical strip 31 together with the sterile gauze 35 from the wound.

[0016] The working principle of the sterile drainage strip for a preauricular fistula provided by this utility model is as follows: After disinfecting the wound, the staff hangs the fixing seat 2 on the patient's ear through the hook 6 and the ear loop 1. Then, the staff pulls the pull block 54, which drives the sliding column 52 to move to the left along the sliding hole 51. The sliding column 52 drives the left rubber pad 7 to move through the arc-shaped clamp 53. At this time, the limiting ring 55 squeezes the spring 56. Then, one end of the cylindrical strip 31 wrapped with sterile gauze 35 is inserted into the wound through the mounting hole 4. The insertion depth is observed through the scale line 37. When the appropriate depth is reached, the pull block 54 is released, and the rebound force of the spring 56 is released. The limiting ring 55 and the sliding column 52 drive the arc-shaped clamp 53 to move to the right until the rubber pads 7 on both sides fix the cylindrical strip 31. The pus in the wound passes through the sterile gauze 35 and flows into the drainage hole 33 through the guide groove 34. Then, it flows into the drainage channel 32 through the drainage hole 33. The drainage holes 33 are all distributed in a circumferential angle around the central axis of the cylindrical strip 31, which effectively improves the drainage effect and has a large suction capacity. It does not need to be replaced frequently. When replacement is required, pull the pull block 54 to release the fixing relationship between the fixing seat 2 and the cylindrical strip 31. Then, lift the protrusion 36 to remove the cylindrical strip 31 together with the sterile gauze 35 from the wound.
