Description

Technical Field

[0001] This utility model relates to the field of stretcher technology, and in particular to a single-person operable rapid shaping stretcher. Background Technology

[0002] A stretcher is a medical transport tool designed specifically for patients with limited mobility or injuries. It is mainly used to safely and efficiently transfer the wounded or patients. Stretchers are usually made of high-strength materials (such as aluminum alloy, canvas, synthetic resin, etc.) and are portable, stable and safe. Its core function is to help medical staff or rescuers reduce secondary injuries to patients in emergency and transport scenarios.

[0003] When using existing stretchers to transport injured persons, medical staff must first carefully and steadily place the injured person on the stretcher surface to ensure that all parts of the injured person's body are in a natural, comfortable, and stable state, so as to avoid aggravating the injury due to improper placement. At this time, the medical staff work together, standing on both sides or around the stretcher, holding the handles firmly with both hands, and relying on their own strength to lift the stretcher to transfer the injured person.

[0004] However, stretchers usually require two people to operate and transport patients simultaneously, while single-operation stretchers are mostly supported by four or three wheels, making them difficult to adapt to transporting patients in complex terrain. In addition, when transporting patients on existing stretchers, the patients are only secured by one or two safety ropes (straps), which can easily cause the patient's body to sway during transport and cause secondary injuries to the injured parts. If the stretcher needs to be tilted in a confined space (such as a narrow elevator), the patient can easily slip off the stretcher. Utility Model Content

[0005] The existing stretchers often require two people to operate and transport the injured, and the patient is prone to swaying during transport, which can cause the patient to slip off the stretcher and cause secondary injury to the injured area.

[0006] The technical solution of this utility model is as follows: a single-person operable rapid shaping stretcher, including a main support rod; it also includes a fixing frame and a shaping pad assembly; an anti-slip handle is fixedly connected to the outside of the main support rod, a shaping pad body is provided on the main support rod, a shaping pad assembly is provided on one side of the shaping pad body, a fixing frame is fixedly connected to the outside of the main support rod, a caster wheel is rotatably connected to the inside of the fixing frame, a support column is fixedly connected to the side of the main support rod away from the fixing frame, a fixed buckle is fixedly connected to the outside of the main support rod, a movable buckle is provided on the outside of the fixed buckle, a shoulder strap is fixedly connected to one side of the movable buckle, a first safety belt is fixedly connected to one side of the main support rod, a first buckle for connection is fixedly connected to one side of the first safety belt, a second safety belt for connection is fixedly connected to the other side of the main support rod, a second buckle is provided on the other side of the second safety belt, and a crossbar is fixedly connected to one side of the main support rod.

[0007] Preferably, there are two sets of anti-slip grips, which are symmetrically arranged at both ends of the main support rod.

[0008] Preferably, there are two sets of the first safety belt, the first buckle, the second safety belt, and the second buckle, and the two sets of the first safety belt, the first buckle, the second safety belt, and the second buckle are symmetrically arranged on the main support rod.

[0009] Preferably, the first buckle has a groove, and the second buckle is engaged with the first buckle through the groove.

[0010] Preferably, the shaping pad assembly includes a flexible top fabric, a flexible top fabric at the upper end of the shaping pad body, a breathable bottom fabric at the lower end of the shaping pad body, the flexible top fabric and the breathable bottom fabric are sewn together, a plastic hose is provided inside the shaping pad body, a feed pipe is fixedly connected to one side of the plastic hose, and a discharge pipe is fixedly connected to the other side of the plastic hose.

[0011] Preferably, two sets of plastic hoses are provided, and the two sets of plastic hoses are symmetrically arranged in the body of the shaping pad.

[0012] Preferably, multiple sets of discharge pipes are provided, and multiple sets of discharge pipes are arranged in a linear array on the plastic hose.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional stretchers, which often require two people to operate and transport, and where the injured person is prone to swaying during transport and slipping off the stretcher, potentially causing secondary injury to the injured area, this device uses a foaming agent to fill the shaping pad. This foaming agent expands in areas not pressed by the body, ultimately embedding the injured person into the shaping pad. By inserting two sets of second buckles into the inside of the first buckle and pulling one end of the second safety belt, the first and second safety belts firmly fix the patient to the shaping pad body, preventing the injured person from swaying, sliding, or falling. The shoulder straps are then worn diagonally on the rescuer's shoulders and chest, making it easier for the person to exert force. When traversing complex terrain, in conjunction with the crossbar, the rescuer can lean forward and brace their waist against the crossbar, reducing the pressure on the casters and minimizing bumps.

A buckle 410 is attached to one side of the main support rod 1, and a crossbar 411 is fixedly connected thereto. Multiple sets of anti-slip grips 2 are symmetrically arranged at both ends of the main support rod 1, providing a more secure grip. Two sets of each of the following are provided: a first safety belt 407, a first buckle 408, a second safety belt 409, and a second buckle 410. These two sets are symmetrically arranged on the main support rod 1. The first safety belt 407, the first buckle 408, the second safety belt 409, and the second buckle 410 are all provided in two sets, thereby simultaneously fixing the upper and lower body of the patient. The first buckle 408 has a groove, and the second buckle 410 is engaged with the first buckle 408 through the groove. The first buckle 408 has a groove, which allows the second buckle 410 to be engaged with the first buckle 408, thereby fixing the first safety belt 407 and the second safety belt 409 together.

[0023] Please see Figures 4-5 In this embodiment, the shaping pad assembly includes a flexible top fabric 501, a flexible top fabric 501 at the upper end of the shaping pad body 3, and a breathable bottom fabric 502 at the lower end of the shaping pad body 3. The flexible top fabric 501 and the breathable bottom fabric 502 are sewn together. A plastic hose 503 is provided inside the shaping pad body 3. A feed pipe 504 is fixedly connected to one side of the plastic hose 503, and a discharge pipe 505 is fixedly connected to one side of the plastic hose 503. Two sets of plastic hoses 503 are provided, and the two sets of plastic hoses 503 are symmetrically arranged inside the shaping pad body 3. The two sets of plastic hoses 503 facilitate the injection of environmentally friendly polyurethane foaming agent into the shaping pad body 3. Multiple sets of discharge pipes 505 are provided, and multiple sets of discharge pipes 505 are arranged in a linear array on the plastic hoses 503. The multiple sets of discharge pipes 505 ensure that the environmentally friendly polyurethane foaming agent is evenly distributed inside the shaping pad body 3.

[0024] During the procedure, the injured person is lifted onto the shaping pad body 3, and then two sets of second buckles 410 are inserted into the inside of the first buckle 408. By pulling one end of the second safety belt 409, the first safety belt 407 and the second safety belt 409 firmly fix the patient to the shaping pad body 3. Environmentally friendly polyurethane foam is injected into the plastic hose 503 through the feed pipe 504, and then the environmentally friendly polyurethane foam is sprayed out from the discharge pipe 505 into the shaping pad body 3, where it is quickly shaped and fixed according to the human body shape. To prevent the injured person from swaying, sliding, or falling, the shoulder strap 406 is worn diagonally on the shoulders and chest of the rescuer, making it easier for the rescuer to exert force. When traversing complex terrain, in conjunction with the crossbar 411, the rescuer can lean forward and exert force while bracing their waist against the crossbar 411, which can reduce the ground pressure of the casters 402 and reduce bumps. The shaping pad body 3 not only has the function of shaping according to the human body shape and fixing the injured person, but also has the functions of shock absorption and protection, because the foaming agent is also injected between the human body and the bottom cloth, and after expansion, it forms a foam pad under the human body.

[0025] Through the above steps, the two sets of second buckles 410 are inserted into the inside of the first buckle 408. By pulling one end of the second safety belt 409, the first safety belt 407 and the second safety belt 409 firmly fix the patient to the shaping pad body 3 to prevent the injured person from shaking, sliding, or falling. Then, the shoulder strap 406 is worn diagonally on the shoulders and chest of the rescuer, which makes it easier for the person to exert force. When passing through complex terrain, in conjunction with the crossbar 411, the rescuer can lean forward and exert force while bracing their waist against the crossbar 411, which can reduce the ground pressure of the caster wheel 402 and reduce bumps.
