Embodiment 1

[0015] Such as figure 1 As shown, the negative pressure flushing isolation device for treating gas gangrene consists of a medical foam dressing 7, two flushing tubes 1, 2 and three drainage tubes 3, 4, 5, the medical foam dressing 7 is a flat three-dimensional structure, and the flushing tube 1, 2 and drainage tubes 3, 4, 5 are hollow tubular structures, the front sections of irrigation tubes 1, 2 and drainage tubes 3, 4, 5 are wrapped in medical foam dressing 7, irrigation tubes 1, 2 and drainage tubes 3, 4 The back section of , 5 is positioned at the outside of medical foam dressing 7, is provided with side hole 6 on the tube wall of irrigation tube 1,2 and drainage tube 3,4,5 wrapped in medical foam dressing 7; What the foam dressing 7 adopted was a medical polyvinyl alcohol foam dressing, specifically a medical polyvinyl alcohol hydrated seaweed salt foam dressing (PVA foam dressing). The quantity of side holes 6 arranged on the pipe walls of flushing pipes 1, 2 and drai...

Embodiment 2

[0018] On the basis of Example 1, a medical adhesive film is added, specifically the medical foam dressing 7 of the negative pressure flushing isolation device for the treatment of gas gangrene described in Example 1 is covered with a medical adhesive film. The adhesive film is a transparent and breathable adhesive film made of polyester material, which is a biological semipermeable film.

Embodiment 3

[0020] The specific operation in use of the negative pressure irrigation isolation device for the treatment of gas gangrene described in embodiment 1:

[0021] (1) the patient's affected limb is fully debridement, thoroughly removes necrotic tissue and foreign matter on the wound surface, wipes the skin around the wound surface with alcohol, and uses the medical foam dressing (PVA) of the negative pressure flushing isolation device for the treatment of gas gangrene described in Example 1 Foam dressing) covers the entire wound. Large wounds need to be spliced ​​in multiple pieces. The edge of the medical foam dressing and the skin at the edge of the wound are intermittently sutured to prevent it from moving. Drainage tubes and irrigation tubes can be drawn directly from the wound or from normal tissues around the wound. The backup tube can be temporarily closed, and it will be activated when the drainage tube and / or flushing tube are blocked;

[0022] (2) the medical adhesive ...

Abstract

The invention provides a negative-pressure flushing isolating device for treating gas gangrene. The device comprises medical foam dressing, a rinsing pipe and a drainage pipe. The front section of the rinsing pipe and the front section of the drainage pipe are wrapped in the medical foam dressing, the rear section of the rinsing pipe and the rear section of the drainage pipe are located outside the medical foam dressing, lateral holes are formed in the pipe walls of the rinsing pipe and drainage pipe wrapped in the medical foam dressing, and the device can also comprises a standby pipe. The upper side of the medical foam dressing is covered with a medical adhesive membrane. When the device is used, the drainage pipe is connected with a negative pressure device, and the rinsing pipe is connected with a potassium permanganate solution for continuous rinsing and direct oxidation and sterilization; a local environment with high oxygen partial pressure concentration is locally generated on a wound surface, so that a low-oxygen environment required by growth and reproduction of clostridia is eliminated. By means of the device, open wound surfaces generated after operations of gas gangrene patients are converted into closed wound surfaces, so that wound surface treatment is conducted in a closed system, and the infection risk and the medical work intensity can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a device for treating gas gangrene, in particular to a negative pressure flushing isolation device for treating gas gangrene. Background technique [0002] In recent years, frequent traffic accidents, construction site trauma, mine accidents, large-scale natural disasters, and local conflicts have continuously increased the scale and number of trauma patients. In many places, the epidemic of infectious diseases in the follow-up treatment of trauma has further caused even greater disasters. Among them, gas gangrene is a severe infectious disease that makes the majority of medical staff and wounded people turn pale. Because of its pathogenic bacteria widely exist in nature such as soil, water, skin, and once infected, it is often disabled or fatal rapidly because of its dangerous condition. Moreover, because of its highly contagious characteristics, once it occurs, it is very easy t...
