Description

Technical Field

[0001] The present invention relates to the field of wound tissue treatment, and in particular to a wound flushing and drainage treatment system and method with a one-button inspection function. Background Art

[0002] In recent years, the newly emerging closed negative pressure drainage (VSD) has been clinically proven to be applicable to the coverage and drainage of acute and chronic wound ulcers and large soft tissue defects on the body surface. Its application in traumatic osteomyelitis has naturally become a treatment method for clinical physicians. Currently, the VSD wound covering materials on the market are mainly biosynthetic materials such as foam or sponge. During the application process, they cannot remove viscous exudate and necrotic and detached tissue. The most common problem is the blockage of the drainage tube, which leads to an increase in the number of bacteria and a significant odor, which is not conducive to wound healing.

[0003] Effective wound irrigation combined with negative pressure therapy can help remove wound exudate, necrotic tissue, bacteria, and toxins from the wound bed and promote wound healing.

[0004] Generally speaking, negative pressure drainage therapy equipment only has two treatment modes: continuous negative pressure and intermittent negative pressure. Patent CN2020112236114 discloses a treatment mode of flushing and suction at the same time. Patent CN201980070547X manually sets the amount of flushing fluid to start the treatment, and the machine treats according to the set program. In the intermittent negative pressure treatment mode and the flushing treatment mode, medical staff cannot immediately understand whether there is any air or fluid leakage in the wound and the patient's feelings when the suction is stopped. If the pipeline is blocked and needs to be flushed, it is necessary to return to the current treatment mode, manually set the control flushing, and reset the parameters after the flushing to return to the flushing mode before the blockage, which brings many inconveniences to clinical work.

[0062] Usage and principle of the present invention

[0064] 1. In the intermittent suction strong mode and intermittent suction painless mode, after pressing the one-button check button, the medical staff can immediately check whether the intermittent suction mode is working normally, and check the wound surface (i.e. the wound dressing) after the negative pressure source is cut off and the patient's feelings;

[0065] 2. In the strong flushing and soaking mode and the painless flushing and soaking mode, after pressing the one-button check button, the medical staff can immediately check whether the flushing and soaking mode is working properly, whether the flushing liquid is too much or too little under the state of intelligent control of the flushing liquid volume, and whether there is any leakage from the wound during soaking. Third, whether the wound condition and patient feelings in the flushing and soaking mode are checked;

[0066] 3. In intermittent flushing mode, after pressing the one-button check button, the medical staff can immediately check whether the flushing system is working properly. Secondly, if there is a lot of necrotic tissue in the wound or drainage tube, the button is not released, and the flushing system keeps pumping water to manually flush in real time to remove necrotic tissue and bacterial toxins. After releasing the button, it returns to the first stage normally. It has no effect on the parameter setting of the treatment system. There is no need to temporarily set the flushing volume in the screen operating system. After the flushing is completed, reset the normal flushing volume. Third, check the condition of the wound and the patient's feelings in the flushing immersion mode.
