Description

Negative pressure wound treatment device and control method thereof

Technical field

The invention relates to the field of medical instruments, in particular to a negative pressure wound treatment device for promoting wound healing and a control method thereof.

Background technique

Negative Pressure Wound Therapy (NPWT) technology is an advanced wound treatment technique developed in recent years that promotes wound healing primarily through lower negative pressures (typically -55 mmHg to 175 mmHg). When negative pressure attracts the cell membrane and causes the cell membrane to expand and distort, the cell will then transmit a "cell membrane damage" signal to the nucleus, thereby causing the nucleus to secrete a large number of pre-healing growth factors, including vascular proliferation factors, to stimulate the wound. The tissue of the face produces more neovascularization and accelerates the healing of the wound surface.

In response to the above-mentioned negative pressure wound treatment technology, countries have successively developed corresponding large-scale negative pressure wound treatment equipment and portable negative pressure wound treatment equipment. Among them, the portable negative pressure wound treatment device needs to press the button of the operation panel during the operation, and the panel and the button are often disposed on the side facing the user for the convenience of the patient and the medical staff.
