Description

Technical Field

[0001] The utility model relates to the field of medical facilities, in particular to a hospital bed which is convenient for postoperative care and dressing change of hemorrhoids. Background Art

[0002] Importance and methods of dressing change: Dressing change after hemorrhoid surgery is essential for preventing infection and promoting wound healing. Improper dressing change may lead to wound infection or slow healing. When changing the dressing, the patient usually takes the knee-chest or side-lying position, and uses the hands to spread the buttocks to expose the surgical wound. The doctor will use fingers to separate the anus and disinfect the local wound with iodine cotton balls. Dressing change after hemorrhoid surgery is usually performed 1-2 times a day to avoid destroying the new granulation tissue, which leads to slow wound healing; while too little or no dressing change may lead to false healing of the wound. When changing the dressing, the action needs to be gentle to avoid damage to the new tissue. If the wound is large or there is secretion, it can be rinsed with disinfectant, saline or metronidazole, and then ointment or suppository can be used, and drainage gauze can be placed on the wound. Recovery cycle: The natural recovery cycle of hemorrhoids is usually one month. During hospitalization, the dressing is changed 1-2 times a day. The condition usually improves significantly after half a month, and the frequency of dressing change can be reduced until the wound is completely healed. After the wound heals, it is recommended to maintain the habit of cleaning the anus for a long time to prevent hemorrhoids from recurring.

[0003] Improper dressing changes may lead to wound infection or slow healing. When changing the dressing, the patient usually takes the knee-chest or side-lying position, and uses his hands to spread the buttocks apart to expose the surgical wound. The doctor will use his fingers to separate the anus and use iodine cotton balls to disinfect the local wound.

[0004] When changing dressings, patients are in great pain, so it is difficult for them to maintain or change body posture in such a painful state, which also affects the operation of medical staff. Therefore, reasonably structured auxiliary facilities are needed. Utility Model Content
