Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a stretcher for transporting patients. Background Technology

[0002] A stretcher is a medical device used to transport the wounded and sick. It is typically made of materials such as metal, plastic, or wood, and generally consists of two long poles as a support, connected in the middle by a bed or sling to support the body. Some stretchers are also equipped with handles, wheels, brakes, and folding mechanisms for ease of operation and transport. They are mainly used in medical emergency situations, battlefield rescue, and accident scenes to safely and smoothly transfer the wounded and sick from the location of injury to medical treatment facilities such as ambulances and hospitals, minimizing secondary injury to the wounded and sick during transport. Depending on the specific use case and needs, there are various types of stretchers, such as the aforementioned folding stretchers, scoop stretchers, basket stretchers, roll-up stretchers, multi-functional stretchers, and spinal fixation stretchers.

[0003] In the prior art, Chinese patent CN219190194U discloses a stretcher that facilitates patient transfer, belonging to the field of medical device technology. It addresses the problem that when staff readjust patient positions, the nursing pad easily shifts or becomes tangled on the stretcher.

The setting of the telescopic rod 3 can adjust the height of the support rod 1. Loosening the locking ring 5, in conjunction with the use of the connecting frame 2 and the threaded shaft 4, allows the telescopic rod 3 to rotate, turning the telescopic rod 3 to a horizontal position against the support rod 1, and retracting the roller 7, making it easier for personnel to lift the device.

[0032] Working principle: When using this device, the cloth pad 8 allows the patient to lie down comfortably. The ventilation holes 9 facilitate back ventilation after the patient lies down. The cotton pad 10 enhances the softness of the cloth pad 8, thereby improving the comfort of the device. The device can be lifted by the support rod 1 and the handle 15, making it easy to move the patient. The connecting hole 11 and the buckle 12 facilitate the connection between the cloth pad 8 and the support rod 1 with a rope, making the cloth pad 8 easy to disassemble and clean after long-term use. The threaded telescopic column 14 can adjust the distance between the handle 15 and the support rod 1, thereby adjusting the length of the device. The anti-slip sleeve 16 provides anti-slip function when lifting the device.

[0033] The axle 6 and roller 7 at the bottom of the telescopic rod 3 make it easy to place the device on the ground and push it, thus saving effort when moving patients, reducing workload, and improving the practicality of the device. The telescopic rod 3 can adjust the height of the support rod 1. Loosening the locking ring 5, in conjunction with the connecting frame 2 and the threaded shaft 4, allows the telescopic rod 3 to rotate. When the telescopic rod 3 is rotated to a horizontal position and close to the support rod 1, the roller 7 can be retracted, making it easier for personnel to lift the device.
