Description

Technical Field

[0001] The utility model relates to the technical field of hospital nursing, in particular to a nursing stretcher which is convenient for folding and unfolding. Background Art

[0002] A nursing stretcher is an auxiliary tool for transporting the injured. For example, Patent No. CN 215229368 U discloses a hospital nursing stretcher that is easy to fold. The first connecting block and the second connecting block can be connected by a rotating shaft to achieve the foldable function of the lifting and placing body. The lifting and placing body can be fixed after it is stretched out by adapting the clamping column and the clamping hook to prevent poor stability during use. The body of the injured person can be fixed and limited during use by adapting multiple Velcro tightening straps to each other to prevent falling during movement. At the same time, when the lifting and placing body is folded and stored, it can be fastened by the Velcro tightening strap to prevent it from opening by itself, making storage and placement more convenient.

[0003] The above disadvantages:

[0004] Since most nursing stretchers are mobile stretchers with foldable supporting legs at the bottom, and the supporting legs of the above nursing stretcher can only be folded and retracted, although this makes it convenient to retract the stretcher, the supporting height of the supporting legs cannot be adjusted during use, which makes the entire stretcher inflexible to operate during use, especially when using a vehicle for transportation, the inability to adjust the supporting height makes it impossible to use a variety of transportation spaces.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 The nursing stretcher shown is easy to fold and unfold, including a lifting and placing body 1. The four corners of the bottom of the lifting and placing body 1 are provided with support structures for supporting the height folding and unfolding. A rotating shaft 8 for strengthening the support is arranged horizontally and longitudinally in the middle of the bottom end of the lifting and placing body 1. Velcro fastening belts 5 are symmetrically arranged on both sides of the lifting and placing body 1. Through the adhesion between the relatively arranged Velcro fastening belts 5, it is convenient to tie up the patient and improve the safety factor. The front and back of the lifting and placing body 1 are provided with pushing structures for easy grasping and pushing during the operation of the entire stretcher.

[0022] A support groove is provided in the middle of the top of the lifting and placing body 1, and a bag cloth 6 is provided inside the support groove. The bag cloth 6 is a nylon fiber woven cloth to protect the patient from secondary injury. The pushing structure includes a stretcher handle 101 for grasping provided on the front and back of the lifting and placing body 1.

[0023] When the patient lies on the shawl 6, the patient is lifted up by the rotating shaft 8 arranged in the middle of the bottom, thereby reducing the pressure on the shawl 6 and making the whole stretcher safer to lift and use.

[0024] Two hinge seats 7 are horizontally and longitudinally symmetrically arranged on the front and back of the bottom of the lifting and placing body 1, and the top of the supporting structure is hinged to the bottom of the hinge seat 7. The supporting structure includes an adjusting rod 2 hinged to the bottom of the hinge seat 7, a supporting tube 3 is slidably sleeved on the bottom of the adjusting rod 2, and a locking piece for positioning the bottom of the adjusting rod 2 and the supporting tube 3 is arranged between the interlaced part.

[0025] A storage groove is opened on one side of the bottom of the adjusting rod 2, and the locking part includes a locking rod 9 which is slidably inserted and connected in the storage groove. The outer wall of one side of the support tube 3 is opened with multiple locking holes 301 in the vertical direction, and the end of the locking rod 9 away from the adjusting rod 2 is slidably inserted and connected with one of the locking holes 301.

[0026] The inner walls of the top and bottom of the storage chute are provided with limiting chute, the top and bottom of the locking rod 9 are fixedly connected with limiting sliders 11, the limiting sliders 11 are slidably inserted and connected in the limiting chute on the corresponding side, and a supporting spring 10 is provided between the sides of the storage chute and the horizontal and longitudinal sides opposite to the locking rod 9, and the supporting spring 10 always presses the locking rod 9 in the direction away from the adjusting rod 2, thus ensuring the stability of the locking rod 9 when plugging. The bottom of the support tube 3 is provided with a self-locking universal wheel 4 to facilitate the daily transportation of the nursing stretcher.

[0027] When the utility model is in operation, the patient is lifted and placed on the nursing stretcher, and is tied up by the Velcro fastening belt 5 , and the medical staff grasps the stretcher handle 101 to push or lift the entire stretcher.

[0028] When the support height needs to be adjusted, the locking rod 9 needs to be pressed in the direction close to the support tube 3. The locking rod 9 moves after being subjected to force, and drives the connected limiting slider 11 to slide synchronously in the corresponding limiting slide groove. At the same time, the supporting spring 10 will be compressed during the movement of the locking rod 9. When the locking rod 9 is completely embedded in the support tube 3, the interlaced connection position between the support tube 3 and the adjusting rod 2 can be pulled to adjust the support height. In this way, the support height can be adjusted. After the adjustment is completed, under the push of the restoring force of the supporting spring 10, the locking rod 9 is inserted into the locking hole 301 at the corresponding height position to complete the positioning.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
