Embodiment 1

[0036] Wound negative pressure suction system, if attached figure 1 As shown: it is mainly composed of a housing 1, a communication port 3, a chamber 2, a negative pressure mechanism, a right end cover 16, a water absorption mechanism, a binding plate 19, a card slot and an alarm mechanism. The housing 1 is covered with a binding plate 19, and the binding plate 19 is provided with a slot for placing the housing 1. The slot is C-shaped, and the side of the binding plate 19 facing away from the slot is fixed with a binding for binding. belt 21, the patient can engage the shell 1 on the slot of the binding plate 19, and fix the shell 1 and the binding plate 19 on the patient's leg or hand through the strap 21, so that the patient can The medium can walk freely, which greatly accelerates the speed of wound healing, enhances the healing effect, and promotes the growth of granulation.

[0037] The left part of the housing 1 is provided with a communication port 3, the communication...

Embodiment 2

[0050] The difference between this embodiment and embodiment 1 is: as attached Figure 4 As shown, the alarm mechanism is mainly composed of a second magnet 25, a second magnetic induction switch 26, and a second alarm 27. The side of the sliding support seat 9 is fixed with the second magnet 25, and the inner wall of the housing 1 side is provided with The second accommodating groove, the second magnetic induction switch 26 and the second alarm 27 are installed in the second accommodating groove, the second magnetic induction switch 26 is matched with the second magnet 25, and the second magnetic induction switch 26 is electrically connected to the second alarm 27 Even, the second receiving groove can cooperate with the second cover plate for sealing. The second magnetic induction switch 26 can be a commonly used magnetic induction switch, preferably a cylindrical proximity switch with a signal of SP121 / SP122 produced by Shenzhen Xinwei Technology Development Co., Ltd.

Abstract

The invention relates to the field of medical devices, and discloses a wound negative pressure attraction system. The system comprises a housing body. A cavity chamber and a communication opening arearranged in the housing body. The communication opening communicates with the cavity chamber. A negative pressure mechanism used for forming negative pressure at the communication opening is arrangedin the cavity chamber. The negative pressure mechanism comprises a sliding support seat slidably connected to the interior of the cavity chamber. A first sealing ring is detachably connected to one end, close to the communication opening, of the sliding support seat. A spring fixing seat is detachably connected with one end, away from the communication opening, of the housing body. A first insertion opening is arranged in the spring fixing seat. A pushing insertion pin is movably connected to the interior of the first insertion opening. Rotation shafts are arranged on two sides of the first insertion opening and are rotatably connected to the spring fixing seat. Springs are arranged on the rotation shaft. The other end of each spring is fixed to a fixed part of the sliding support seat. According to the invention, the attraction system is small in size and light, generates quite low noise, and is low in manufacturing cost and suitable for use in basic medical institutions like communities; it is convenient for a patient to move and carry the attraction system; there is no need to charge the attraction system; medical care payment can be greatly reduced; and the attraction system has quite high promotion and use value.

Description

technical field [0001] The invention belongs to the field of medical equipment. Background technique [0002] With the development of society and the improvement of people's living standards, there are more and more acute and chronic wounds, such as diabetic foot ulcers, venous lower extremity ulcers, compression ulcers caused by long-term bed rest, and local ulcers caused by peripheral arterial disease. , burns and surgical wounds. Despite the great advances in medicine today, the treatment of wound healing remains a challenge. [0003] Vacuum sealing drainage (VSD) is a brand-new method for dealing with various complex wounds and for deep drainage. Compared with various existing surgical drainage techniques, VSD technology is a revolutionary progress . This technology was pioneered in 1992 by Dr. Fleischmann, a trauma surgeon at ULM University in Germany, and was first used in the orthopedic field to treat soft tissue defects and infected wounds. In 1994, Professor Qiu...
