Technical Field

[0001] The utility model relates to the technical field of pressure sore prevention negative pressure closed drainage, in particular to a pressure sore prevention negative pressure closed drainage device specially used for chronic, refractory wounds. Background Art

[0002] Negative pressure sealed drainage: mainly used for chronic wounds such as pressure sores and diabetic foot (mostly on the sacrum and foot). Since the patients are old and have difficulty in moving, they cannot maintain a pressure-free posture for a long time. If the suction cup and pipeline are under pressure for a long time, it is easy to cause pressure sores. In order to avoid the pain and cost of repeated dressing changes for chronic difficult-to-heal wounds, negative pressure is installed. After a negative pressure is installed, it takes 7 to 10 days to remove it, which is very inconvenient and not conducive to wound healing.

[0003] To this end, we propose a negative pressure closed drainage device for preventing pressure sores specifically for chronic, refractory wounds to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Negative pressure sealed drainage: mainly used for chronic wounds such as pressure sores and diabetic foot (mostly on the sacrum and foot). Since the patients are old and have difficulty in moving, they cannot maintain a non-pressure posture for a long time. If the suction cup and pipeline are under pressure for a long time, it is easy to cause pressure sores. In order to avoid the pain and cost of repeated dressing changes, negative pressure is installed for chronic difficult-to-heal wounds. After a negative pressure is installed, it takes 7 to 10 days to remove it, which is very inconvenient and not conducive to wound healing. Therefore, refer to Figure 1-3 This scheme designs a negative pressure closed drainage device for preventing pressure sores specifically for chronic, difficult-to-heal wounds, comprising a fixing belt 1, a drainage tube 2, an action tube 3, and a negative pressure chamber 4. The negative pressure chamber 4 is used to act on the action tube 3 to generate a negative pressure state. The action tube 3 is connected to the drainage tube 2 for drainage operations, and the fixing belt 1 is used to be fixed to the wound of the patient.

[0021] Specifically: the drainage tube 2 is set through the fixing belt 1, and the drainage tube 2 is fixedly connected to the fixing belt 1, the action tube 3 is fixed inside the negative pressure chamber 4, and the action tube 3 is set across the negative pressure chamber 4, the drainage tube 2 is disconnected in the middle and connected to the action tube 3, the action tube 3 is divided into three sections, the head and tail sections of the action tube 3 are hard structures, the hard structure will not be affected by the negative pressure chamber 4, the middle section of the action tube 3 is made of elastic material, and will be affected according to the pressure state of the negative pressure chamber 4. When the negative pressure chamber 4 is pressed, the negative pressure chamber 4 will be in a negative pressure state during the recovery process. At this time, the middle part of the action tube 3 will expand, thereby generating a negative pressure state inside the action tube 3, and then achieving the drainage effect.

[0022] In order to ease the negative pressure state of the action tube 3 and make it smoothly connected, multiple elastic ropes 7 are fixedly connected to the inside of the negative pressure chamber 4. The elastic ropes 7 are fixedly connected to the middle section of the action tube 3. Therefore, during the rebound process, the elastic ropes 7 will restrain the action tube 3 and slowly restore its deformation. At the same time, multiple partitions 8 are rotatably connected to the inner walls of the head and tail sections of the action tube 3. The partitions 8 are tilted. The negative pressure chamber 4 is made of elastic material. During the pressing process, one of the partitions 8 opens and the other partition 8 closes. During the reset process, the two partitions operate in the opposite direction, thereby forming a one-way The effect of the valve is to prevent the drainage tube 2 from affecting the negative pressure state. At the same time, the diameter of the air hole 5 on the negative pressure chamber 4 does not exceed 0.5 cm. A plurality of air holes 5 are provided on the negative pressure chamber 4 to maintain good air inlet and outlet efficiency, which will not be too fast or too slow. Because too fast air outlet and air intake will cause the interior of the negative pressure chamber 4 to be in a short-term negative pressure effect, it cannot affect the action tube 3 well, so the action force of the action tube 3 is not strong, and too slow air outlet and air intake will not only affect the efficiency, but also affect the action tube 3. The change is too slow and does not act well on the action tube 3.

[0023] A suction cup 9 is fixedly connected to the end of the drainage tube 2, and the drainage tube 2 passes through the suction cup 9. The suction cup 9 is set in the fixing belt 1. The fixing belt 1 is provided with a break, and a magic felt 6 is bound at the break. The suction cup 9 is used to perform a short-term adsorption operation on the local position to prevent it from affecting the entire wound. Then, the fluid is drained into the drainage tube 2 through the suction cup 9 to achieve a better drainage effect and prevent the wound from being injured.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
