[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model are described in detail below.
[0023] like Figures 1-2 As shown, a sterile, malleable arterial catheter fixation dressing includes a film 1, a low-temperature thermoplastic plate 2, a dressing patch 3, a bump 4, and an antibacterial gel 5. The film 1 includes a first film 11 and a second film 12, both of which are medical transparent films 1.
[0024] like Figures 1-2 As shown, the first film 11 is located below the second film 12, and one side of the first film 11 is fused to the second film 12. After the first film 11 is bonded to the skin, the second film 12 can be opened upward with the fusion line of the first film 11 and the second film 12 as the center.
[0025] like Figures 1-2 As shown, the low-temperature thermoplastic plate 2 is positioned above the first film 11 along the length direction of the film 1. The low-temperature thermoplastic plate 2 is connected to the second film 12. The low-temperature thermoplastic plate 2 is slightly smaller than the first film 11. Therefore, when the low-temperature thermoplastic plate 2 is placed on the first film 11, the low-temperature thermoplastic plate 2 will not come into contact with the patient's skin.
[0026] like Figures 1-2 As shown, this avoids the problem of the low-temperature thermoplastic plate 2 irritating the skin. The second film 12 itself is larger than the first film 11. Therefore, when the second film 12 covers the first film 11 and the low-temperature thermoplastic plate 2, the four sides of the second film 12 will extend beyond the first film 11 and the low-temperature thermoplastic plate 2.
[0027] like Figures 1-2 As shown, when the second film 12 is placed on the low-temperature thermoplastic plate 2, the four sides of the second film 12 can be adhered to the patient's skin, thereby restricting the position of the low-temperature thermoplastic plate 2.
[0028] like Figures 1-2 As shown, the low-temperature thermoplastic sheet 2 itself is thermoplastic. Therefore, after heating the low-temperature thermoplastic sheet 2 using a warm box or hot air blower, the softened low-temperature thermoplastic sheet 2 can be shaped according to the shape we need.
[0029] like Figures 1-2 As shown, after the low-temperature thermoplastic plate 2 is shaped and cooled, it will maintain a fixed shape. After the first film 11 is attached to the patient's skin, the shaped low-temperature thermoplastic plate 2 can be placed on the first film 11.
[0030] likeFigures 1-2 As shown, the center of the second film 12 is then placed over the low-temperature thermoplastic plate 2, and the area of the second film 12 that extends beyond the low-temperature thermoplastic plate 2 and the first film 11 is then adhered to the patient's skin for fixation.
[0031] like Figures 1-2 As shown, a through hole is provided in the center of the low-temperature thermoplastic plate 2. The through hole in the center of the low-temperature thermoplastic plate 2 is larger than the antibacterial gel 5. When placing the low-temperature thermoplastic plate 2, it is necessary to ensure that the through hole in the center of the low-temperature thermoplastic plate 2 is perpendicular to the antibacterial gel 5. Therefore, when necessary, medical staff can directly observe the state of the antibacterial gel 5 through the through hole in the center of the low-temperature thermoplastic plate 2.
[0032] like Figures 3-5 As shown, the dressing 3 is positioned below the second film 12 along the length of the second film 12, and the size of the dressing 3 is slightly smaller than the second film 12. Therefore, when the second film 12 is covered and stuck on the dressing 3, the four sides of the second film 12 will extend beyond the dressing 3.
[0033] like Figures 3-5 As shown, after the center of the second film 12 is placed over the dressing 3, the area of the second film 12 that extends beyond the dressing 3 is then applied to the patient's skin to fix the dressing 3 in place.
[0034] like Figures 3-5 As shown, a medical breathable mesh 31 is provided at the center of the dressing 3. The medical breathable mesh 31 is adhered to the dressing 3. A through hole is also provided at the center of the medical breathable mesh 31. An opening is provided at one end of the protrusion 4 where the dressing 3 and the medical breathable mesh 31 are located.
[0035] like Figures 3-5 As shown, since the medical breathable mesh 31 is adhered to the dressing 3, and the opening ends of the dressing 3 and the medical breathable mesh 31 are located in the same position, when the opening end of the dressing 3 is opened, the opening end of the medical breathable mesh 31 will also be opened along with the dressing 3.
[0036] like Figures 3-5 As shown, the opening of the medical breathable mesh 31 extends from the opening at the center of the medical breathable mesh 31 to the position of the dressing 3. The opening of the dressing 3 fully opens the end of the dressing 3. The opening end of the dressing 3 includes a first opening end 33 and a second opening end 33.
[0037] like Figures 3-5As shown, the two open ends of the medical air-permeable net 31 are respectively bonded to the first open end 33 and the second open end 33 of the dressing patch 3, and the second open end 33 is provided with an adhesive layer (the adhesive layer is a medical pressure-sensitive adhesive), so that after the first open end 33 and the second open end 33 are opened, the first open end 33 and the second open end 33 can be bonded together again by using the adhesive layer.
[0038] As shown in Figures 3-5 As shown, the medical air-permeable net 31 is provided with a pad 32, which is transversely arranged above the opening of the medical air-permeable net 31, and the lower surface of the pad 32 is divided into two parts, and one part of the lower surface of the pad 32 is bonded to the medical air-permeable net 31 on the side of the first open end 33 by using an adhesive layer.
[0039] As shown in Figures 3-5 As shown, the other part of the lower surface of the pad 32 is connected to the medical air-permeable net 31 on the side of the second open end 33 by using an adhesive layer. When the indwelling needle is punctured, the puncture needle of the indwelling needle will enter the blood vessel of the patient, and the needle holder at the tail end of the puncture needle will be left outside the skin. After the indwelling needle completes the puncture and the dressing patch 3 completes the bonding, the needle holder at one end of the puncture needle can be held up by the pad 32.
[0040] As shown in Figures 3-5 As shown, the protrusion 4 is arranged at the end of the dressing patch 3 and bonded to the first open end 33 of the dressing patch 3, and a fixing patch is arranged above the protrusion 4, one end of the fixing patch is located on one side of the protrusion and is fused and bonded to the first open end 33 of the dressing patch 3.
[0041] As shown in Figures 3-5 As shown, the other end of the fixing patch is located on the other side of the protrusion and is bonded to the first open end 33, so that when needed, the end of the fixing patch with the pressure-sensitive adhesive can be torn off from the first open end 33, and then the fixing patch is opened to expose the protrusion 4.
[0042] As shown in Figures 3-5 As shown, the protrusion 4 is provided with two groups of friction strips made of rubber, which are arranged on the two inner walls of the protrusion 4 and are bonded to the protrusion 4. After the indwelling needle completes the puncture and the dressing patch 3 completes the bonding, the tail end of the needle holder can be held up by the protrusion 4.
[0043] As shown in Figures 3-5 As shown, the needle handle and the needle holder of the indwelling needle are suspended, avoiding direct contact between the needle handle and the needle holder of the indwelling needle and the skin of the patient, thereby avoiding damage to the skin of the patient caused by the indwelling needle. The tail end of the needle holder is placed on the protrusion 4 and directly contacts the friction strip, so that the friction strip increases the friction between the needle holder and the protrusion 4.
[0044] As shown in Figures 3-5As shown, the antibacterial gel 5 is arranged at the through hole in the center of the medical breathable mesh 31 (the antibacterial gel 5 used is a chlorhexidine gluconate gel pad, which is a product in the market, so no further description is given), and the antibacterial gel 5 is slightly larger than the through hole in the center of the medical breathable mesh 31.
[0045] As shown, the antibacterial gel 5 is arranged at the through hole in the center of the medical breathable mesh 31 (the antibacterial gel 5 used is a chlorhexidine gluconate gel pad, which is a product in the market, so no further description is given), and the antibacterial gel 5 is slightly larger than the through hole in the center of the medical breathable mesh 31. Figures 3-5 As shown, after the indwelling needle completes the puncture, the antibacterial gel 5 can be placed at the puncture point of the indwelling needle. The antibacterial gel 5 has excellent antibacterial property, so that after the antibacterial gel 5 is placed at the puncture point of the indwelling needle, the risk of infection of the puncture point caused by bacteria can be reduced.
[0046] As shown, after the antibacterial gel 5 is placed at the puncture point of the indwelling needle, the dressing patch 3 can be adhered to the puncture point of the indwelling needle. When the dressing patch 3 is adhered, the through hole in the center of the medical breathable mesh 31 is ensured to be located above the antibacterial gel 5, so that after the dressing patch 3 is adhered to the skin of the patient, the medical breathable mesh 31 can press the antibacterial gel 5.
[0047] The movement process of the embodiment is as follows: after the indwelling needle completes the puncture, the antibacterial gel 5 is placed at the puncture point of the indwelling needle, and then the end without the opening of the dressing patch 3 is adhered above the puncture needle of the indwelling needle.
[0048] Then, the opening end of the dressing patch 3 is opened, and the first opening end 33 and the second opening end 33 are moved from the two sides of the needle seat of the indwelling needle to below the needle seat, and then the first opening end 33 and the second opening end 33 are adhered together by the adhesive layer.
[0049] The opening end of the dressing patch 3 adhered together is adhered to the skin of the patient, and when the dressing patch 3 is adhered, the through hole in the center of the medical breathable mesh 31 is ensured to be located above the antibacterial gel 5.
[0050] Then, the cushion block 32 is moved to the front end of the needle seat and supports the front end of the needle seat by the cushion block 32, and then the cushion block 32 is adhered to the medical breathable mesh 31 by the adhesive layer, and then the fixing patch is opened and the tail end of the needle seat is placed on the protrusion 4.
[0051] After the needle handle of the indwelling needle is ensured to be suspended, the tail end of the needle seat is fixed on the protrusion 4 by the fixing patch, and then the center of the first film 11 covers the dressing patch 3, and then the remaining part of the first film 11 is adhered to the skin of the patient, and then the low-temperature thermoplastic plate 2 is shaped according to the puncture position.
[0052] If the indwelling needle is punctured at the radial artery position, the front end of the low-temperature thermoforming plate 2 is shaped according to the shape of the palm behind the puncture point, and the tail end of the low-temperature thermoforming plate 2 is shaped according to the shape of the arm in front of the puncture point. After the low-temperature thermoforming plate 2 is shaped and cooled, the shaped low-temperature thermoforming plate 2 can be placed on the first adhesive film 11. When the low-temperature thermoforming plate 2 is placed, the front end of the low-temperature thermoforming plate 2 is ensured to abut against the palm of the patient, and the tail end of the low-temperature thermoforming plate 2 is placed on the arm in front of the puncture point.
[0053] If the indwelling needle is punctured at the radial artery position, the front end of the low-temperature thermoforming plate 2 is shaped according to the shape of the palm behind the puncture point, and the tail end of the low-temperature thermoforming plate 2 is shaped according to the shape of the arm in front of the puncture point. After the low-temperature thermoforming plate 2 is shaped and cooled, the shaped low-temperature thermoforming plate 2 can be placed on the first adhesive film 11. When the low-temperature thermoforming plate 2 is placed, the front end of the low-temperature thermoforming plate 2 is ensured to abut against the palm of the patient, and the tail end of the low-temperature thermoforming plate 2 is placed on the arm in front of the puncture point.
[0054] If the indwelling needle is punctured at the radial artery position, the front end of the low-temperature thermoforming plate 2 is shaped according to the shape of the palm behind the puncture point, and the tail end of the low-temperature thermoforming plate 2 is shaped according to the shape of the arm in front of the puncture point. After the low-temperature thermoforming plate 2 is shaped and cooled, the shaped low-temperature thermoforming plate 2 can be placed on the first adhesive film 11.
