Description

Technical Field

[0001] The invention relates to medical device technology, and in particular to a wound dressing change support frame. Background Art

[0002] In the field of medical care, for the dressing change process of large-area wounds (such as legs, hands, etc.), it is usually necessary to remove the gauze or bandage covering the outside of the wound, clean the wound, apply medicine, and then rewrap new gauze or bandage. This process is not only cumbersome, but also brings great work pressure to medical staff. The traditional dressing change method often requires manual operation by medical staff, which is not only inefficient, but also in the process of removing and wrapping gauze or bandages, it is easy to cause unnecessary pulling on the patient's wound, increase the patient's pain, and may even cause secondary injury to the wound.

[0003] For example, a Chinese invention patent with authorization announcement number CN110074933B discloses a nursing dressing rack, which uses a bandaging device to implement a spiral folding method, which not only avoids the phenomenon of bandage deviation during the bandaging process, but is also suitable for limbs of varying thicknesses, and the bandage is evenly and firmly bandaged, avoiding the problem of bacterial infection caused by contact between the patient's wound periphery and the outside world, and also improves the efficiency of applying medicine. During the bandaging process, the tensioning degree of the bandage can be automatically adjusted by the tensioning mechanism, avoiding the phenomenon of loose bandaging. However, in actual use, for dressing changes on large-area wounds (such as legs, hands, etc.), it can only wrap new gauze or bandages, and it is difficult to effectively realize the two functions of removing the gauze or bandages wrapped around the outside of the patient's wound and wrapping new gauze or bandages.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figures 1 to 4 , a wound dressing support frame, comprising a base 1, a support seat 2, a movable seat 3, a guide member 4, an A drive mechanism 5, an unwinding mechanism 6, a support shaft 7 and a B drive mechanism 8;

[0032] The support seat 2 is fixedly mounted on the base 1, one side of the moving seat 3 is connected to a guide member 4 for limiting the movement of the moving seat 3 along the length direction of the base 1, and the other side of the moving seat 3 is connected to a driving mechanism A 5 for driving the moving seat 3 to move;

[0033] The unwinding mechanism 6 is installed on the movable seat 3. The unwinding mechanism 6 includes a rotating arm 61, a fixing assembly 62 and a driving component. The fixing assembly 62 is used to fix the gauze or bandage. The fixing assembly 62 includes a supporting disk 621. One side of the supporting disk 621 is connected to the driving component. The driving component is used to drive the supporting disk 621 to rotate around itself, and the driving component can drive the supporting disk 621 to move along the length direction of the rotating arm 61.

[0034] One end of the support shaft 7 is fixedly connected to the rotating arm 61, and the other side of the support shaft 7 is connected to a B driving mechanism 8 for driving the support shaft 7 to rotate around its own axis;

[0035] When changing the dressing of a patient's wound, such as a large wound on the leg or hand, the gauze or bandage covering the patient's wound needs to be removed first, the dressing needs to be changed, and then a new gauze or bandage needs to be wrapped around the wound. The whole process is rather cumbersome.

[0036] To this end, the present application provides an unwinding mechanism 6, and the support seat 2 supports the patient's legs or hands. When it is necessary to remove the gauze or bandage covering the outside of the patient's wound, the medical staff manually pulls the end of the gauze or bandage to the fixing component 62, and the fixing component 62 fixes the end of the gauze or bandage, and then drives the rotating arm 61 to rotate around the axis of the support shaft 7 through the B driving mechanism 8. The rotating arm 61 drives the unwinding mechanism 6 to rotate, so that the fixing component 62 pulls the end of the gauze or bandage to rotate, so as to remove the gauze or bandage from the patient's wound. At the same time, the driving component drives the support plate 621 to rotate around its own axis. Thereby, the entire fixing assembly 62 is rotated, and the fixing assembly 62 rolls up the gauze or bandage, which can effectively reduce the work pressure of medical staff. Since such large wounds are covered with more gauze or bandages, the gauze or bandage is tightened during the rolling process, and the gauze or bandage is easy to pull the patient during the rolling process, which may cause secondary damage to the patient's wound. Therefore, during the rolling process, the fixing assembly 62 can be driven by the driving component to move toward the support shaft 7 along the length direction of the rotating arm 61, thereby effectively preventing the gauze or bandage from being over-tightened, which may easily cause secondary damage to the patient's wound.

[0037] After removing the old gauze or bandage, the fixing component 62 is disinfected. After the disinfection is completed, the fixing component 62 supports and fixes the new gauze or bandage, and the medical staff fixes the end of the new gauze or bandage on the patient's wound. Similarly, the rotating arm 61 is driven by the B driving mechanism 8 to rotate around the axis of the support shaft 7, so that the unwinding mechanism 6 rotates, and the fixed component 62 unwinds the gauze or bandage. During the rotation of the unwinding mechanism 6, the gauze or bandage is wound to the outside of the patient's wound, and the movable seat 3 can be synchronously driven to move by the A driving mechanism 5, and the movable seat 3 drives the unwinding mechanism 6 to move synchronously, so that the gauze or bandage can be evenly wound around the outside of the patient's wound.
