Description

Surgical dressing change position changing device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a surgical dressing change body position changing device.

Background technique

Surgery is a treatment method performed by surgeons using instruments and techniques. During surgery or in a surgical clinic, wound dressings need to be changed to keep the wound clean, dry and properly moist to promote wound healing and prevent infection.

The frequency and method of dressing changes will vary depending on the type, severity and treatment plan of the wound. The injured parts of the patients are different, and corresponding support devices are usually required to assist in dressing changes, such as hands, legs, backs, etc. Existing dressing change devices cannot be adjusted according to the above-mentioned parts that need dressing changes, and different dressing change devices can only be used for different patients, such as a surgical wound care dressing change position adjustment device proposed in publication number CN211560912U, which mentions that "the setting of the handle, gear and gear shaft is convenient for adjusting the patient's position, thereby facilitating medical staff to change dressings, and the arm placement slot and leg placement slot avoid the traditional dressing change that only requires the patient to lift his arms or legs to move easily". However, the device is adjusted by a lifting box and cannot perform dressing changes in a lying position. At the same time, the device structure is too simple and has poor applicability, which is not conducive to the efficiency of surgical dressing changes for patients. In view of this, we propose a surgical dressing change position change device.

Example 2

Please refer to Figures 1 to 6. Based on the above embodiments, this embodiment provides a surgical dressing change position changing device. The leg lifting mechanism 6 in the surgical dressing change position changing device includes two groups of fixed blocks 61. The outer side walls of the two groups of fixed blocks 61 are respectively fixedly connected to the inner side walls of the two groups of support rods 11. The outer side walls of the two groups of support rods 11 are hinged with a lifting frame 63. The lifting frame 63 can rotate at a certain angle along the hinge of the support rod 11, so as to help lift the patient's legs and facilitate dressing change on the patient's legs. A pedal 64 is rotatably arranged at the bottom end of the lifting frame 63. The inner side of the pedal 64 is provided with an upward convex surface, which can drag the patient's heel to play a supporting role and prevent the patient from slipping when the leg is lifted for dressing change. When changing the dressing, the patient places the leg on the pedal 64 for lifting to facilitate dressing change.

A worm wheel 611 is rotatably connected to the inner wall of the fixing block 61, and a threaded push rod 62 is threadedly connected to the center of the inner wall of the worm wheel 611. The threaded push rod 62 penetrates and is slidably connected to the inner wall of the support rod 11, and a transverse through groove is provided on the inner wall of the threaded push rod 62, so that it can slide horizontally on the inner wall of the support rod 11 without rotating itself. The rotation of the worm wheel 611 can drive the threaded push rod 62 to move outward and contact the inner side wall of the lifting frame 63, so that it can be folded at a certain angle to lift the patient's legs. The legs can be lifted for dressing change, and because the support rod 11 moves with the support plate 5, after the device is laid flat, the legs can still be lifted by lifting the lifting frame 63, which is convenient for patients to change dressings in various postures. The top of the worm wheel 611 is meshed with a worm 69, and the outer wall of the worm 69 is rotatably connected to the inner wall of the fixed block 61. The central inner wall of the worm 69 is horizontally slidably connected with an insertion rod 68, and the worm 69 is embedded in the insertion rod 68, so that the insertion rod 68 can drive the worm 69 to rotate, and the inner end outer wall of the insertion rod 68 is A plurality of grooves are provided, and the plug rod 68 is plugged with a rotating rod 67. When the plug rod 68 drives the rotating rod 67 to rotate, it drives another group of plug rods 68 to rotate synchronously, thereby driving the two groups of worm gears 611 to rotate, so that the two groups of lifting frames 63 can drive the patient's legs to be lifted synchronously. A protrusion 612 is provided on the outer wall of the plug rod 68. The protrusion 612 on the surface of the plug rod 68 is elastically attached to the outer wall of the rotating block 65 through a reset spring 610. The outer surface of the rotating block 65 is rotatably connected to the inner wall of the fixed block 61. The reset spring 610 can always keep the insertion rod 68 and the rotating rod 67 in an inserted state without being affected by external forces. The insertion rod 68 passes through the inner walls of the rotating block 65 and the fixed block 61. The outer end of the insertion rod 68 is fixedly connected to a crank handle 66, which can more easily drive the insertion rod 68 to rotate. When in use, the crank handle 66 can be moved outward to drive the insertion rod 68 to disengage from the rotating rod 67. At this time, one side of the patient's leg can be lifted and the dressing can be changed separately. It can be switched at will, which is more flexible when changing the dressing on the leg.

The crank handle 66 can also be moved outward before the crank handle 66 is turned to drive the insertion rod 68 to move outward and disengage from the rotation rod 67. At this time, the rotating rod 67 can drive the two sets of worm gears 69 to rotate. The rotation of the worm gear 69 can drive the worm wheel 611 to rotate, thereby causing the threaded push rod 62 in the worm wheel 611 to move outward along the inner wall of the lifting frame 63 and squeeze the outer wall of the lifting frame 63, driving the lifting frame 63 to fold, thereby driving the leg to be lifted, which is convenient for changing the dressing on the leg. The crank handle 66 can also be moved outward before the crank handle 66 is turned to drive the insertion rod 68 to move outward and disengage from the rotation rod 67. At this time, the rotating crank handle 66 can drive the worm wheel 611 on one side to rotate alone, thereby driving the leg on one side to be lifted alone.

The top of the support frame 1 is fixedly connected to a vertical rod 73, and the top of the vertical rod 73 is arranged in an arc shape. The top of the vertical rod 73 is plugged into the bottom end of the placement arc plate 71, and when plugged in, it can play a positioning role for the placement arc plate 71, so that it can be used as an armrest. When the placement arc plate 71 is separated from the vertical rod 73, it can be offset outward by a certain angle, providing a certain activity space for the arm, and providing a support function on the basis of activity, so that the arm can be flexibly adjusted when changing dressings.

In this embodiment, when the arm needs to be changed, the arc plate 71 is moved upward so that it is separated from the vertical rod 73. At this time, the arc plate 71 is rotated outward by a certain angle. The arc plate 71 drops due to its own gravity. At this time, the arc plate 71 can rotate along the support rod 72 at a certain angle to cooperate with the dressing change of the arm.
