Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to an oxygen supply negative pressure treatment device for a wound surface and a preparation method of flushing fluid.
Background
Negative pressure wound therapy is considered to be an effective treatment for promoting wound healing. Negative Pressure Wound Therapy (NPWT) technology is an advanced wound therapy technology developed in recent years, which promotes wound healing mainly by a low negative pressure (typically-55 mmHg to 175 mmHg). When the negative pressure suction acts on the cell membrane and expands and twists the cell membrane, the cells can immediately transmit a 'damage of the cell membrane' signal to the cell nucleus, so that a large amount of pre-healing growth factors including vascular proliferation factors are secreted by the cell nucleus to stimulate tissues of a wound surface to generate more new blood vessels and accelerate the healing of the wound surface.
Negative pressure wound therapy is to place the wound bed of the wound surface in a closed and low oxygen environment, which is easy to cause secondary wound anaerobic bacteria infection, thus providing the viewpoint of oxygen supply negative pressure therapy. The traditional method for oxygen-supply negative pressure wound treatment is as follows: firstly, sealing a wound bed of a wound surface by using a medical film, then introducing oxygen into the wound bed of the wound surface through a humidification bottle, and simultaneously extracting gas in the wound bed through a negative pressure source to keep the interior of the wound bed in a negative pressure state. However, as the oxygen forms gas convection through the wound surface, the wound surface dressing becomes dry along with the time, and the dried dressing can be tightly adhered to the granulation tissue of the wound surface, which is not beneficial to wound healing; modern wound healing theory also clarifies the importance of wet healing for wounds.

the preparation method of the flushing liquid is that the flushing liquid is used for the oxygen supply negative pressure treatment device for the wound surface in the first embodiment and the second embodiment and is prepared by uniformly mixing 20 parts of povidone iodine and 100 parts of normal saline. The povidone iodine can be used as disinfectant with antibacterial effect, and has strong effect in killing virus, bacteria, fungi and mold spore, and has low irritation to skin, low toxicity and long-lasting effect. The physiological saline ensures that the wound surface is in a moist environment, and avoids the wound surface granulation tissue growth influenced by the wound surface dressing after the wound surface dressing is dried; meanwhile, the physiological saline can drain the viscous secretion of the wound surface or other small tissue fragments out of the wound surface, so that the cleanness of the wound surface is ensured, and the wound surface is favorably healed; in addition, the physiological saline can supplement water required by cell growth, so that the cells are not dehydrated, and the cells are prevented from being broken.
Through the raw material preparation of the components, the medicine property is ensured, the concentration of the flushing fluid is also ensured, and the wetting and wound flushing of the flushing fluid are not influenced; the flushing fluid of the invention not only can moisten and flush the wound surface, but also can treat the wound surface through other preparations, thereby accelerating the healing of the wound surface.
The washing liquid is used for the wound surface with inflammation.
Example four:
the preparation method of the flushing liquid is characterized in that the flushing liquid is used for the oxygen supply negative pressure treatment device for the wound surface in the first embodiment and the second embodiment and is prepared by uniformly mixing and stirring 2 parts of shellfish refreshment and 100 parts of physiological saline. When the inflammation of the wound subsides, in order to further promote the healing of the wound, the shellfish can be used for restoring and matched with normal saline to be instilled on the wound; the beraprost can repair and regenerate epithelial cells, fibroblasts, dermal cells, vascular endothelial cells and the like and promote the regeneration of capillary vessels, thereby accelerating the healing of wound surfaces; meanwhile, the physiological saline can drain the viscous secretion of the wound surface or other small tissue fragments out of the wound surface, so that the cleanness of the wound surface is ensured, and the wound surface is favorably healed; in addition, the physiological saline can supplement water required by cell growth, so that the cells are not dehydrated, and the cells are prevented from being broken.
The washing liquid is used for the wound surface with controlled inflammation or easily resolved inflammation.
As another embodiment of the present invention, when the wound surface has inflammation, the irrigation solution of example three is used, and after the inflammation of the wound surface subsides, the irrigation solution of example four is replaced.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
