Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to an auxiliary device for changing dressings on a patient's wound. Background Technology

[0002] Wound dressing change assistive devices fall under the field of medical assistive device technology. In medical care, changing dressings for patients with limited mobility is a common and important task. Currently, medical staff often require patients to cooperate by raising their arms or legs, or using simple tools such as chairs to elevate the affected area for easier dressing changes. This process not only causes inconvenience for both patients and medical staff, but also easily leads to fatigue and even injury for medical staff due to prolonged bending or squatting, affecting work efficiency and quality.

[0003] In existing technologies, the following methods are commonly used to improve the convenience of dressing change operations: First, ordinary chairs or raised objects are used as support tools, and the height is manually adjusted to adapt to different dressing change needs; second, simple slings or ropes are used to fix and suspend the patient's arms or legs, making it easier for medical staff to operate; third, a fixed support structure is used to support the dressing change site through a pre-set height.

[0004] The aforementioned existing technologies generally suffer from a lack of flexibility, particularly in adapting quickly to varying height requirements, and fail to effectively address the physical strain on medical staff caused by prolonged bending or squatting. Furthermore, traditional methods often require additional human assistance, increasing the complexity of the work for medical personnel. Therefore, there is an urgent need for an auxiliary device that is flexibly adjustable in height, easy to move, and simple to operate to improve this situation. Utility Model Content

[0005] This application provides an auxiliary device for changing dressings on patient wounds, which is both height-adjustable and easier to move.

[0006] This application provides an auxiliary device for changing dressings on patient wounds, which adopts the following technical solution:

[0007] An auxiliary device for changing dressings on a patient's wound includes a pulley assembly. A retractable bracket is provided on the top of the pulley assembly. A fixed bracket is connected to the top of the retractable bracket. Multiple guide pulleys are provided below the fixed bracket. Pull ropes are provided on the guide pulleys. One end of the pull rope is connected to a lifting structure.

[0008] By adopting the above technical solution, this utility model designs an auxiliary device for changing dressings on patient wounds. During use, medical staff can flexibly adjust the height and position of the device to meet the needs of different patients. Specifically, the pulley system allows the entire device to be easily moved to the required position, reducing the workload of medical staff in moving equipment; the telescopic support can be adjusted in height according to the patient's specific situation, ensuring that dressing changes are performed in a suitable position and avoiding physical strain on medical staff due to frequent bending or squatting. Furthermore, the lifting structure effectively supports the patient's injured area, providing a stable environment for dressing changes while reducing patient discomfort.

[0009] Preferably, the pulley assembly includes multiple rolling pulleys and a disc, with the rolling pulleys mounted on the bottom of the disc to move the device.

[0010] By adopting the above technical solution, the pulley system consists of multiple rolling pulleys and a disc during use. The rolling pulleys are installed at the bottom of the disc, enabling flexible movement of the device. This design allows the entire auxiliary device to be easily moved to the patient's side as needed, improving the portability and applicability of the equipment, avoiding the inconvenience of medical staff manually carrying the device, and also providing patients with more convenient conditions for dressing changes.

[0011] Preferably, the telescopic bracket includes multiple telescopic rods that are nested together, and adjacent telescopic rods are fixed together by locking devices.

[0012] By adopting the above technical solution, the telescopic bracket is composed of multiple telescopic rods that are interlocked during use, and adjacent telescopic rods are fixed by locking components, so that the overall height of the device can be adjusted as needed.

[0013] Preferably, the locking component includes a locking block disposed on the telescopic rod, and the telescopic rod is provided with multiple locking holes. The telescopic rod can be fixed by using the locking bolts on the locking block to cooperate with the locking holes.

[0014] By adopting the above technical solution, the cooperation between the locking block and the locking hole allows the telescopic rod to be quickly locked after being adjusted to the required height, thus avoiding safety hazards caused by height instability during use.

[0015] Preferably, the guide pulley is provided with an annular groove, the pull rope is wound around the guide pulley, and the annular groove can be used to lock the annular housing to prevent the pull rope from falling off the guide pulley.

[0016] By adopting the above technical solution, when in use, an annular groove is provided on the guide pulley, and the pull rope is wound around the guide pulley. The annular groove can be used to lock the annular housing to prevent the pull rope from detaching from the guide pulley.

[0017] Preferably, the lifting structure includes multiple lifting ropes at one end of the pull rope, and a support sleeve is connected to the lifting rope. The support sleeve is used to support the arm or thigh that needs to be treated.

[0018] By adopting the above technical solution, the support sleeve can stably support the patient's arm or thigh that needs treatment during use. The setting of multiple suspension ropes makes the support sleeve evenly stressed, avoiding instability caused by single-point stress, thereby ensuring the safety and comfort of the patient's limb during the suspension process.

[0019] Preferably, the support sleeve is provided with massage bumps, which can make the placement area more comfortable and prevent it from falling off.

[0020] By adopting the above technical solution, the massage bumps on the support sleeve allow the patient's arm or leg placed on the support sleeve to obtain better comfort when using the device, relieving discomfort caused by prolonged placement.

[0021] Preferably, an automatic winch mechanism is provided at the end of the pull rope away from the lifting structure. The automatic winch mechanism includes a winder fixed to the end of the pull rope. The winder is equipped with a motor and a retraction wheel. The motor drives the retraction wheel to rotate, causing the pull rope on the retraction wheel to retract, thereby controlling the lifting and lowering of the lifting structure.

[0022] By adopting the above technical solution, the automatic winch mechanism makes the raising and lowering of the rope more convenient during use, eliminating the need for manual operation and reducing the workload of medical staff. Specifically, the motor drives the retraction wheel to rotate, realizing the automatic retraction and release of the rope, thereby precisely controlling the raising and lowering of the lifting structure and improving operational efficiency and comfort.
