Description

Technical Field

[0001] The utility model relates to the technical field of walkers, in particular to a multifunctional walker. Background Art

[0002] Malignant tumors are the disease with the highest mortality rate in the Chinese population. Among female malignant tumors, cervical cancer, endometrial cancer, and ovarian cancer rank second, fifth, and sixth respectively. Gynecological tumors are mainly treated with surgery, with laparotomy being the most common. Due to the large abdominal wound, patient care faces the following problems: 1. The wound is large in scope. Patients have a long recovery time after surgery, and they use their abdominal muscles to get out of bed, and they need help from others for pain from the wound. 2. Most patients with gynecological tumors are elderly, with comorbidities such as diabetes and hypertension. Patients with heavy weight, in particular, have difficulty getting out of bed and need help and support from multiple people. 3. There are many infusion routes after surgery, making movement inconvenient. 4. Risk of falls High-risk factors in obstetrics and gynecology include: abnormal vision (myopia ≥ 500 degrees), cardiovascular disease (hypertension, coronary heart disease, etc.), gynecological laparotomy within 3 days, treatment with drugs (sedatives, paralysis, diuretics, psychiatric drugs, hypoglycemics, antihypertensives, laxatives, anti-tumor drugs, etc.), anemia, etc., and the high-risk factors basically cover the population of gynecological tumor patients. The risk of falling is extremely high and the use of walkers is required. 5. The concept of accelerated recovery after surgery (ERAS) is the main measure for the rehabilitation of postoperative patients in the early stage. Walkers are of great help to the patient's mobility and comfort experience. 6. The current clinical use is a single-liquid stent, and the wheelchair has no auxiliary function. Therefore, a multi-channel infusion device can be hung to assist walking. There is an obvious demand for a convertible wheelchair with multi-functional integrated walker.
