Description

A medical dressing with a sensor system and its fixing method

technical field

The invention relates to the technical field of medical devices, in particular to a medical dressing with a sensor system and a sensor fixing method thereof.

Background technique

Surgical dressings are necessary medical dressings in surgical operations. According to the 2008 "Journal of the American College of Surgeons" (Cima RR, Kollengode A, Garnatz J, et al. Incidence and characteristics of potential and actual retained foreign object events in surgical patients. J Am Coil Surg 2008; 207: 80-87.) According to a recent study, in abdominal surgery, the probability of foreign bodies remaining in the body is relatively high, about 1 in 1,000 to 1,500. "New England Journal of Medicine" (GawandeAA, Studdert DM, Orav EJ, et al. Risk factors for retained instruments and sponges after surgery. NEngl J Med 2003; 348: 229-235.) has also published important articles showing that foreign bodies remain in the body Dressings accounted for 69% of the cases studied. Foreign bodies of fibrous tissue origin, such as gauze or towels, tend to form lumps known as gossypiboma/textiloma/gauzoma. Its main harm, on the one hand, causes great physical and mental harm to patients. Patients with gauze residue may suffer from the following complications: pain, infection, post-abscess granuloma, fistula or intestinal obstruction. The removal of foreign bodies often requires a second operation. For example, most residual foreign bodies in the abdominal cavity are removed by laparotomy, especially gauze tumors. If it is not removed for a long time, it will cause irreversible necrosis of the tissue and even threaten the life of the patient. On the other hand, the surgical team that performs the operation needs to face related medical malpractice compensation and lawsuits.

The key reason for leftover surgical dressings is errors in counting and identification. Also in the aforementioned JACS article it was shown that of 34 cases of foreign body residues, 21 cases were considered correct (62%). It is difficult to identify the existence of the dressing with the naked eye after it is soaked in blood. In addition, a variety of surgical instruments and a large number of dressings are needed during the operation, and other factors in the operation, such as the psychological quality of the medical staff, the operating environment, etc. The length of time, etc., may cause errors in the counting of surgical dressings. At this time, the medical staff mistakenly believed that all medical instruments and dressings had been taken out, thus causing foreign bodies left in the patient's body. In order to solve this potential safety hazard, it is urgent to develop a new technology so that medical dressings can be detected, traced, and counted by electronic equipment, so as to realize reliable anti-surgical auxiliary monitoring.

Medical dressings are attached with sensors, so that each piece of medical dressing has a unique identification code, which perfectly solves the problem of common medical dressings being left in the patient's body due to the cumbersome counting process and unrecognizable. On the one hand, it realizes the real-time, accurate and intelligent counting of medical dressings before, during and after the operation; it greatly reduces the work intensity of the medical staff during the operation, and enables the medical staff to devote more energy to the operation itself. On the other hand, before the surgical incision is sutured, the corresponding detector can be used to detect the surgical area to reconfirm whether there is any dressing left in the patient's body. Through the above-mentioned double insurance method, the leftover of gauze is eliminated, the safety of patients' operations is greatly improved, and the increasingly tense relationship between doctors and patients in China is promoted.

Fixing sensors with recognition functions to the inner or outer surface of dressings is a challenging task. On the one hand, the medical dressings used in surgery are strictly sterilized, so the sensor system must meet various sterilization requirements. On the other hand, surgical dressings are in direct contact with human tissue and blood, and the sensor system attached to the dressing must also consider biocompatibility, and allergies, cytotoxicity, etc. must not occur. At the same time, it is also necessary to ensure that the sensor does not affect the traditional performance, usage and user habits of surgical accessories. The invention perfectly solves the problem of the combination of the sensor and the common medical dressing, thereby effectively solving the problem of the medical dressing remaining in the patient's body.
