AI Technical Summary
The existing wound negative pressure drainage set lacks effective prompting function, which makes it difficult for medical staff to observe the accumulation of effusion in the drainage bottle. The excessive suction force can easily lead to the skin tissue being sucked by the drainage tube, causing congestion inside the skin.
A wound negative pressure drainage set is designed, using a combination of transparent frame, fluorescent float, scale, through hole and safety helmet. The floating of fluorescent float indicates that the effusion is close to fullness, and through the coordination of drainage tube, soft pads and hollow holes, the risk of skin tissue being absorbed is reduced.
It realizes rapid observation and timely replacement of full drainage bottles by medical staff, avoiding the problems of skin tissue being sucked up and internal congestion, and improving the safety and efficiency of negative pressure drainage of wounds.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1-5 The utility model provides an embodiment: a wound negative pressure drainage kit, including a drainage bottle 5, a drainage tube 17 and a puncture needle 22. The wound negative pressure drainage kit includes a drainage bottle 5, a drainage tube 17, a puncture needle 22, a drainage outer tube, a fixed suture needle thread, a fixed needle patch, a sterile dressing, a sterile tweezers, gloves and a closed sterile outer packaging. The upper part of the drainage bottle 5 is fixedly connected with a port 9, the upper outer periphery of the port 9 is threadedly connected with a top cover 2, the outer periphery of the top cover 2 is fixedly connected with a fixing ring 3, and the lower part of the fixing ring 3 is fixedly connected with a breaking protrusion 12. An easy-folding tube 8 is arranged on the right side of the upper part of the drainage bottle 5, and a safety valve 7 is fixedly connected to the upper end of the easy-folding tube 8. The safety valve 7 is a one-way valve, which can be used to evacuate the inside of the drainage bottle 5 through a vacuum pumping device. At the same time, when the vacuum pumping device exits the safety valve 7, it can ensure that the inside of the drainage bottle 5 is in a sealed state.
[0034] The skin at the patient's wound is punctured by using a skin puncture needle 22, and then the puncture needle 22 is withdrawn to allow one end of the drainage tube 17 to penetrate into the skin, and then the other end of the drainage tube 17 is connected to the connector 1, and then the pipeline of the vacuum pumping device and the safety valve 7 are connected, and the vacuum pumping device is started to extract the air inside the drainage bottle 5 through the easy-fold tube 8, so that a negative pressure state is formed inside the drainage bottle 5, and then the pipeline of the vacuum pumping device and the safety valve 7 are separated, so that the safety valve 7 can seal the front end of the easy-fold tube 8, so that the inside of the drainage bottle 5 maintains a negative pressure state, a needle 10 is fixedly connected to the middle part of the top cover 2, the upper end of the needle 10 is fixedly connected to the connector 1, and a sealing film 11 is fixedly connected to the lower side of the port 9, a transparent frame 6 is provided at the front of the drainage bottle 5, a fluorescent float 14 is provided inside the transparent frame 6, a safety cap 13 is fixedly connected to the top of the transparent frame 6, a through hole 15 is provided on the lower side of the rear of the transparent frame 6, and a scale 16 is provided on the inner wall of the transparent frame 6.
[0035] After being ready, the medical staff tightens the top cover 2 to make it move downward along the outside of the port 9, so that the needle 10 inside the top cover 2 can move downward and puncture the sealing film 11. At this time, the negative pressure inside the drainage bottle 5 will cause the needle 10 to generate suction, and the accumulated fluid inside the wound is sucked into the drainage bottle 5 through the drainage tube 17 connected to the connector 1. As the accumulated fluid continues to enter the drainage bottle 5, the accumulated fluid will enter the transparent frame 6 through the through hole 15, thereby lifting the fluorescent float 14 inside the transparent frame 6. As the accumulated fluid increases, the fluorescent float 14 continues to float upward. The medical staff can determine the volume of the accumulated fluid inside the drainage bottle 5 by observing the position of the fluorescent float 14, and accurately read the volume of the accumulated fluid through the scales 16 distributed on the inner wall of the transparent frame 6. When the fluorescent float 14 is pushed to the lower part of the safety cap 13 by the accumulated fluid, the accumulated fluid inside the drainage bottle 5 is close to being full. The medical staff can replace the drainage bottle 5 in time to prevent the accumulated fluid inside the drainage bottle 5 from overflowing.
[0036] A cushion 18 is fixedly connected to the lower part of the drainage tube 17. When the drainage tube 17 attracts the accumulated fluid inside the wound, the skin tissue is sucked up by the drainage tube 17 due to the excessive suction force. The soft cushion 18 can separate the skin tissue and the drainage tube 17, thereby buffering the skin tissue and avoiding congestion inside the skin tissue. The upper end of the puncture needle 22 is fixedly connected to the interface 21.
[0037] The needle 10 is arranged on the upper part of the sealing film 11. As the top cover 2 is twisted, the needle 10 will pierce the sealing film 11 downwards, thereby sucking the accumulated fluid in the wound. The breaking protrusion 12 is located on the left side of the middle part of the easy-to-fold tube 8. After the accumulated fluid is full, the top cover 2 can be twisted to loosen it. As the top cover 2 continues to move upward along the port 9, the breaking protrusion 12 at the lower part of the fixing ring 3 will contact the easy-to-fold part in the middle part of the easy-to-fold tube 8, thereby breaking the easy-to-fold tube 8. Subsequently, the top cover 2 will also be removed from the outside of the port 9, so that the drainage bottle 5 cannot be used again after opening, ensuring that the wound negative pressure drainage suit can only be used once to avoid cross infection caused by multiple patients using it. The through hole 15 is connected to the inside of the drainage bottle 5, and the accumulated fluid in the drainage bottle 5 will enter the transparent frame 6 through the through hole 15, thereby floating the fluorescent float 14. A plurality of evenly distributed hollow holes 19 are arranged inside the soft pad 18, and the hollow holes 19 can further help the soft pad 18 buffers the skin tissue at the patient's wound to avoid congestion inside the skin tissue. The lower end of the puncture needle 22 is provided with a knife tip 23, which can easily puncture the skin, and then the puncture needle 22 is fixed on the skin by a fixed needle patch, so as to facilitate the insertion of the drainage tube 17 into the wound along the puncture needle 22. After the drainage is completed, the wound can be sutured by fixing the suture needle and thread, and then a sterile dressing is applied to the wound. The puncture needle 22 and the middle part of the interface 21 are provided with a drainage channel 20, and the drainage channel 20 can discharge excessive effusion after the puncture needle 22 pierces the skin. The lower end of the easy-to-fold tube 8 is connected to the inside of the drainage bottle 5, and the upper end of the easy-to-fold tube 8 is connected to the safety valve 7. The inside of the drainage bottle 5 is vacuumed through the safety valve 7 such as a one-way valve structure, so as to keep the inside of the drainage bottle 5 in a negative pressure state. The upper two sides of the drainage bottle 5 are fixedly connected with fixing holes 4, and the drainage bottle 5 is fixed to the patient's bedside through the fixing holes 4 and a rope.
[0038] Working principle: Use the skin puncture needle 22 to puncture the patient's wound skin, then withdraw the puncture needle 22, let one end of the drainage tube 17 penetrate into the skin, then connect the other end of the drainage tube 17 to the connector 1, then connect the pipeline of the vacuum pumping device to the safety valve 7, start the vacuum pumping device to extract the air inside the drainage bottle 5 through the easy-fold tube 8, so that a negative pressure state is formed inside the drainage bottle 5, then separate the pipeline of the vacuum pumping device and the safety valve 7, so that the safety valve 7 can seal the front end of the easy-fold tube 8, so that the inside of the drainage bottle 5 maintains a negative pressure state. After preparation, the medical staff tightens the top cover 2 to move it downward along the outside of the port 9, so that the needle 10 inside the top cover 2 can move downward and puncture the sealing film 11. At this time, the negative pressure inside the drainage bottle 5 will cause the needle 10 to generate suction, and suck the accumulated fluid inside the wound into the drainage bottle 5 through the drainage tube 17 connected to the connector 1. As the accumulated fluid continues to enter the drainage bottle 5, the accumulated fluid will pass through the The hole 15 enters the interior of the transparent frame 6, thereby lifting the fluorescent float 14 inside the transparent frame 6. As the accumulated fluid increases, the fluorescent float 14 continuously floats upward. Medical staff can determine the volume of the accumulated fluid inside the drainage bottle 5 by observing the position of the fluorescent float 14, and accurately read the volume of the accumulated fluid through the scale 16 distributed on the inner wall of the transparent frame 6. When the fluorescent float 14 is pushed to the lower part of the safety cap 13 by the accumulated fluid, the accumulated fluid inside the drainage bottle 5 is close to being full, and the medical staff can promptly Replace the drainage bottle 5 to prevent the accumulated fluid inside the drainage bottle 5 from overflowing. After the accumulated fluid is full, the top cover 2 can be twisted to loosen it. As the top cover 2 continues to move upward along the port 9, the breaking protrusion 12 at the bottom of the fixing ring 3 will contact the easy-to-break part in the middle of the easy-to-break tube 8, thereby breaking the easy-to-break tube 8. Subsequently, the top cover 2 will also be removed from the outside of the port 9, so that the drainage bottle 5 cannot be used again after it is opened, ensuring that the wound negative pressure drainage kit can only be used once to avoid cross infection caused by multiple patients using it.
