Intraoperative and postoperative auricle intermittent positive pressure inflating device

Abstract

The invention provides an intraoperative and postoperative auricle intermittent positive pressure inflating device and belongs to the field of medical instruments. The intraoperative and postoperative auricle intermittent positive pressure inflating device comprises an outer shell, two air bags disposed in the outer shell and an air bag inflating and deflating control device connected with the air bags. The outer shell is provided with a sleeving opening and the two air bags are fixed to the inner walls of the outer shell on the two sides of the sleeving opening; a cavity for sleeving the auricle is formed between the two air bags. The width between the two air bags matches the width of the sleeving opening. The intraoperative and postoperative auricle intermittent positive pressure inflating device is used by sleeving the auricle with the sleeving opening, so that the fixation is convenient and falling-off is prevented; the inner walls of the two sides in the outer shell are provided with the air bags and the ear is located between the two air bags; through the inflating and deflating of the air bags, the auricle is massaged to promote the blood circulation of the auricle, the recovery speed is increased and the complications are reduced; the control device is used for the air bag inflating and deflating and comprises a pressure sensor and a wireless transmission module, so that a patient can freely set the massage force, frequency and time through an instrument terminal or a cell phone terminal when in need according to instructions of doctors.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an intermittent positive pressure inflation device for auricle during and after operation. Background technique [0002] In clinical practice, large tissue avulsions of ear, nose, lip and other organs are often encountered due to severe trauma, and only a small amount of tissue is connected to the body. Such tissue blocks cannot be reconstructed by microsurgical methods because they do not have blood vessels that can be anastomosed. In this way, if the avulsed tissue block is removed by debridement, it will inevitably lead to loss of affected tissue and secondary deformity. If the ultra-length-to-width ratio skin flap or tissue block is directly sutured to repair the wound of the tissue block, blood circulation disorder, especially venous return disorder, will occur after the operation. All necrosis will lead to serious complications. If the venous blood stasis is not im...

Problems solved by technology

According to statistics, after skin flap transplantation, the incidence of venous crisis caused by local venous return disorder is much higher than that of arterial crisis. In facial plastic surgery, ear plastic surgery is more common in plastic surgery. Finally, because the blood vessels at the sutured site are cut off, it is difficult to rebuild the blood supply in a short period of time, and it is easy to cause poor local blood circulation, which seriously affects the postoperative recovery of the patient. How to enhance blood circulation, reduce complications, and make the surgical part as soon as possible Recovery is the direction of technology in the industry
