[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a portable, multifunctional, temperature-controlled stretcher blanket. (See also...) Figure 1 and Figure 4A portable multi-functional constant temperature stretcher blanket includes a lower stretcher blanket 1, with several pull ropes 3 fixedly connected to the surface of the lower stretcher blanket 1, a second male and female zipper cord 12 fixedly connected to the surface of the lower stretcher blanket 1, a second zipper head 11 movably connected to the surface of the second male and female zipper cord 12, and an upper stretcher blanket 2 fixedly connected to the surface of the second zipper head 11 through the second zipper head 11 and the second male and female zipper cord 12. The surface of the lower stretcher blanket 1 is provided with three fixing mechanisms 7.

[0025] A bottom padding 6 is fixedly connected to one side of the lower layer 1 of the stretcher. The bottom padding 6 is located below the lower layer 1 of the stretcher. The front and back sides of the bottom padding 6 are fixedly connected to the first male and female zipper ropes 9. The surface of the first male and female zipper ropes 9 is movably connected to the first zipper head 8. The front and back sides of the lower layer 1 of the stretcher and the bottom padding 6 are fixedly connected through the first zipper head 8 and the first male and female zipper ropes 9. The surface of the upper layer 2 of the stretcher is fixedly connected to the female zipper rope 10. The surface of the female zipper rope 10 is movably connected to the surface of the first male and female zipper rope 9.

[0026] Reference Figure 2 A third zipper cable 14 is fixedly connected to the surface of the lower layer 1 of the stretcher. A third zipper head 13 is movably connected to the surface of the third zipper cable 14. A foot protector 5 is movably connected to the top of the lower layer 1 of the stretcher. The lower layer 1 of the stretcher and the foot protector 5 are fixedly connected by the third zipper head 13 and the third zipper cable 14. By setting the foot protector 5, the third zipper head 13 and the third zipper cable 14 in cooperation, the feet of the injured person are protected on the surface of the lower layer 1 of the stretcher. The foot protector 5 can be removed from the surface of the lower layer 1 of the stretcher by the third zipper head 13 and the third zipper cable 14 for easy replacement and cleaning.

[0027] Reference Figure 1 and Figure 2 The stretcher is fixedly connected to the top of the lower layer 1 with a head protection sleeve 4. The head protection sleeve 4 is semi-circular in shape and made of elastic material. The head protection sleeve 4 is used to protect the head of the injured person at the top of the lower layer 1 of the stretcher, so as to avoid the injured person's head from being accidentally hit during the transport process and causing secondary injury.

[0028] Reference Figure 2 and Figure 3The fixation mechanism 7 includes three first straps 701 and three second straps 702. One end of each first strap 701 and second strap 702 is fixedly connected to the surface of the lower layer 1 of the stretcher. The other end of the first strap 701 is fixedly connected to a locking block 709. The other end of the second strap 702 is fixedly connected to a connector 703. The inner cavity of the connector 703 is movably connected to a fixing block 704. The surface of the fixing block 704 is movably connected to the inner cavity of the locking block 709. By setting the first strap 701, the second strap 702, the connector 703, the fixing block 704, and the locking block 709 to work together, when the connector 703 drives the fixing block 704 to lock into the inner cavity of the locking block 709, the first strap 701 and the second strap 702 bind and fix the injured person, reducing the possibility of the injured person slipping or shaking during transportation.

[0029] Reference Figure 3 A guide groove 708 is provided on one side of the surface of the snap-fit ​​block 709. The guide groove 708 is set at an angle. There are two guide grooves 708. The surface of the guide groove 708 is movably connected to the surface of the fixing block 704. The guide groove 708 provides a guiding effect for the fixing block 704 when it is inserted into the cavity of the snap-fit ​​block 709, so that the fixing block 704 can be smoothly inserted into the cavity of the snap-fit ​​block 709.

[0030] Reference Figure 3 and Figure 4 A spring 705 is fixedly connected to the surface of the fixing block 704. One end of the spring 705 is fixedly connected to the inner cavity of the plug 703. With the spring 705, when the fixing block 704 is not affected by external force, the elastic effect of the spring 705 always has an outward force, so that it can be more stably snapped into the inner cavity of the snap block 709.

[0031] Reference Figure 4 The inner cavity of the connector 703 is provided with a sliding groove 707, and a sliding block 706 is movably connected to the inner cavity of the sliding groove 707. The surface of the sliding block 706 is fixedly connected to the surface of the fixed block 704. By setting the sliding block 706 and the sliding groove 707, the stability of the fixed block 704 sliding in the inner cavity of the connector 703 is improved, while the fixed block 704 plays a limiting role when sliding in the inner cavity of the connector 703, so as to prevent the fixed block 704 from detaching from the inner cavity of the connector 703 when sliding in the inner cavity of the connector 703.

[0032] Reference Figure 2 The stretcher is fixedly connected to the inner side of the upper layer 2 with an insulation layer 15, which is made of graphene insulation material.

[0033] Working principle: When a patient needs to be transported on the lower layer 1 of the stretcher, firstly, pull the second zipper head 11 to slide it onto the surface of the second zipper cable 12, separating the zipper cable 12. Then, move the patient onto the lower layer 1 of the stretcher. Next, pick up the connector 703 and the fixing block 704. The connector 703 and the fixing block 704 will drive the first strap 701 and the second strap 702 to bind and secure the patient. Then, insert the connector 703 into the inner cavity of the locking block 709. During the insertion process, the connector 703 will drive... The fixing block 704 slides on the surface of the guide groove 708 of the locking block 709. The inclined surface of the guide groove 708 exerts pressure on the fixing block 704, causing the fixing block 704 to slide into the inner cavity of the connector 703. At the same time, the spring 705 deforms until the fixing block 704 slides into the inner cavity of the locking block 709. At this point, due to the elasticity of the spring 705, the fixing block 704 moves and locks into the inner cavity of the locking block 709. At this time, the second strap 702 and the first strap 701 are fixed, thereby securing the injured person on the top of the lower layer 1 of the stretcher. After securing the injured person, their feet can be protected by inserting them into the inner cavity of the foot protector 5, and their head can be protected by inserting them into the inner cavity of the head protector 4. The insulation layer 15 of the upper layer 2 of the stretcher blanket can increase the warmth of the injured person's body. Then, the rescuers lift the rope 3 to raise the injured person on the lower layer 1 of the stretcher blanket. When it is necessary to temporarily place the injured person on the ground, the bottom padding 6 at the bottom of the lower layer 1 of the stretcher blanket will reduce the possibility of secondary injury to the injured person due to uneven ground because of the soft insulation layer inside. When the stretcher is lifted, since the bottom of the lower layer 1 does not require soft support, the first zipper head 8 can be pulled to slide on the surface of the first zipper cable 9, separating the zipper cable 9. Then, the bottom pad 6 is flipped over to the surface of the upper layer 2 of the stretcher blanket, and the first zipper head 8 is pulled again to engage the female zipper cable and the female zipper cable 10 of the first zipper cable 9, thereby fixing the bottom pad 6 to the surface of the upper layer 2 of the stretcher blanket and increasing the warmth of the upper layer 2 of the stretcher blanket for the wounded.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
