Description

Technical Field

[0001] The invention relates to the technical field of wound care, in particular to a postoperative wound care device. Background Art

[0002] Thoracic surgery is a medical specialty that focuses on the study of organs within the chest cavity, primarily the diagnosis and treatment of esophageal, lung, and mediastinal lesions. The field of breast surgery is also included in this specialty, with lung surgery and esophageal surgery being the main focus. After undergoing thoracic surgery, patients need to use chest protectors and other devices to protect the surgical incision.

[0003] Traditional wound care devices may have many problems. On the one hand, the fixing method of the medicine package is not reliable enough or the operation is complicated. The medicine package is easy to move during use, and it is impossible to ensure stable contact with the wound, which affects the therapeutic effect of the drug on the wound. For example, a simple placement method may be adopted, lacking effective limiting and fixing structures, and the medicine package is easy to shift during patient activities or care. At the same time, traditional care devices may be insufficient in terms of comfort and wound recovery environment creation. There may be a lack of good ventilation design, which leads to stuffiness in the wound, increases the risk of infection, and is not conducive to wound healing. At the same time, there may be no effective dust prevention measures, and impurities such as dust can easily enter the wound, affecting the cleaning and recovery of the wound.

[0014] Beneficial Effects Compared with the prior art, the present invention provides a postoperative wound care device, which has the following beneficial effects: 1. The postoperative wound care device, through the synchronous limiting mechanism, can automatically fix the medicine pack in the placement cavity when the mounting plate enters the placement cavity. Specifically, after the first connecting column moves downward and contacts with the fourth push plate, it drives a series of parts to move, such as the fourth push plate drives the third push plate to move downward, the third push plate drives the second push plate to move upward through the first push plate, and the second push plate drives the limiting plate to extend out of the fixing box and contact the top of the first connecting column through the tooth block part and the rotating gear, thereby achieving effective fixation of the mounting plate and the medicine pack, preventing the medicine pack from moving during use, and ensuring that the medicine pack can accurately act on the patient's postoperative wound.

[0015] 2. The postoperative wound care device can fix the first connecting column through a limit slider under the action of a spring to prevent the mounting plate and the medicine package from moving up and separating from the patient's chest wound, thereby increasing the close contact between the medicine package and the patient's chest wound, which is conducive to better drug effect and promotes wound healing.

[0016] 3. When installing the medicine pack in the postoperative wound care device, it is only necessary to slide the toggle block to one side in the second sliding through hole to release the restriction of the limit slider on the first connecting column, and then place the mounting plate and the medicine pack into the placement cavity. The operation process is simple and easy to understand, and it is convenient for medical staff to use.

[0017] 4. The postoperative wound care device has a care frame with ventilation holes and dustproof plates, which dissipate heat through the ventilation holes, maintain ventilation, reduce stuffiness, and improve the patient's comfort. At the same time, the dustproof plate can prevent dust and other impurities from entering the wound through the ventilation holes, providing a relatively clean recovery environment for the wound. The bottom of the care frame is provided with convex strips at equal intervals, which are in contact with the patient's skin, reducing the large-area contact between the care frame and the patient's skin, further reducing the risk of wound ulceration due to long-term contact with airtightness, and is conducive to the recovery of the wound.
