Description

A hand-cranked dressing changing brace

technical field

The utility model relates to the technical field of medical instruments, in particular to a hand-operated dressing changing brace.

Background technique

Dressing change is a very important part of orthopedic surgery, especially after tibia and fibula fractures. Because of the special anatomy of the injury, poor blood circulation of the wound, and prolonged healing time, it is very important for doctors to change dressings. In order to prevent postoperative infection, the affected limb The wound dressing should be changed 2 to 3 days after the operation, and the wound healing should be observed. The patient cannot lift it up for the doctor to change the dressing due to the pain of the wound. Nurses or assistants are often used to elevate the affected limb, and the support/lift is often artificially replaced. The wrong posture increases the pain of the patient, reduces the comfort level of the patient and affects its rest, and delays recovery.

The Chinese utility model patent with the application number "201320250556.7", the authorized announcement number "CN203280659U" and the name "dressing support" discloses a dressing support, including a base, a connecting rod and a pad, and the base is two The steel pipes are fixed by connecting rods between the two steel pipes; the base is connected with a support pad through a support shaft, and an adjustment screw is arranged on the support shaft. The dressing support can be given to patients whose limbs need to be raised during surgery or normal nursing operations, but the raised height is not adjustable and cannot be adjusted according to the actual needs of each patient. Therefore, during use certain limitations arise.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a dressing-changing brace for legs that can be adjusted in height according to the actual needs of different patients.

In order to achieve the above purpose, the utility model provides a hand-operated dressing support, which includes two bases, a connecting rod, two support pads and two support shafts, and the two bases pass through the The connecting rod is fixed, one end of each of the two support shafts is respectively connected to a support pad, and the other end is respectively a free end, and each base is provided with a hand-operated lifting mechanism inside, and the hand-operated lifting mechanism includes two fixed frame, a rack, a shaft and a gear, wherein:

The two fixing frames are arranged in parallel in the base, and the rotating shaft is installed between the two fixing frames, and one end of the rotating shaft extends out of the base, and a gear is also arranged on the rotating shaft;

A hole is longitudinally set on the base, and the free end of the support shaft extends into the base through the hole and then connects to the rack. . By rotating the rotating shaft, the intermeshing rack and pinion can slide the support shaft up and down and adjust the height of the support pad, so that the height of the support pad can meet the needs of different patients, and the operation is convenient and flexible.

Preferably, the two fixing brackets are respectively arranged on the top of the inner wall of the base.

Preferably, the side of the gear facing the rack has a tooth groove structure, and the side of the gear facing away from the rack has an arc-shaped edge structure. The outer circumference of the gear transitions from the tooth groove structure towards the rack side to the arc-shaped side structure, so that the rack has a certain meshing range on the gear. The edge structure is locked.

The beneficial effect of the utility model is that the structure is simple, the up and down sliding of the support shaft and the height adjustment of the support pad can be realized by rotating the rotating shaft, and it can be used for patients whose limbs need to be raised during surgery or nursing operations, and can be raised according to different patients. Getting to an appropriate position improves patient satisfaction, not only saves the time of medical staff, but also does not affect the healing of the operation, and the local skin does not appear to be compressed.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.

Example 1:

A hand-operated dressing change support as shown in Figure 1, including two bases 1, a connecting rod 2, two support pads 3 and two support shafts 4, the two bases 1 pass through the The connecting rod 2 is fixed, one end of each of the two supporting shafts 4 is respectively connected to a support pad 3, and the other end is a free end, and each base 1 is provided with a manual lifting mechanism inside, and the manual lifting The mechanism includes two fixed frames 5, a rack 6, a rotating shaft 7 and a gear 8, wherein:

The two fixed mounts 5 are arranged in parallel in the base 1, the rotating shaft 7 is installed between the two fixed mounts 5, one end of the rotating shaft 7 stretches out of the base 1, and the rotating shaft 7 is also provided with a gear 8;

A hole 9 is provided longitudinally on the base 1, and the free end of the support shaft 4 extends into the base 1 through the hole 9 and then connects to the rack 6, the gear 8 is engaged with the rack 6, and the rack 6 is engaged The opposite side of the side is attached to the inner wall of the base 1 . By rotating the rotating shaft 7, the intermeshed gear 8 and rack 6 realize the vertical sliding of the support shaft 4 and the height adjustment of the support pad 3, so that the height of the support pad 3 can meet the needs of different patients, and the operation is convenient and flexible.
