Description

Technical Field

[0001] The invention relates to a stretcher for picking up the wounded, in particular to an insertable stretcher for picking up the wounded with small posture disturbance. Background Art

[0002] For severely injured patients with spinal injuries, traditional stretchers are often used to transport them. The process of manually lifting or dragging them onto the stretcher can easily change their body posture, causing secondary damage to the already injured spine. In mild cases, this can lead to high-level paraplegia, while in severe cases, it can be life-threatening. Therefore, while transferring the injured to the stretcher, how to effectively minimize the disturbance in their posture during the transfer process to avoid secondary damage to the spinal cord remains a technical challenge.

[0003] Existing stretchers for seriously injured patients usually insert the stretcher under the patient's body while trying not to lift the body. The more common ones are longitudinally spliced ​​stretchers. Designers pursue convenience and speed in use. For seriously injured patients with spinal injuries, the most taboo during transportation is posture disturbance in two directions, one is the twisting of the spine, and the other is the bending of the spine. This conventional longitudinally spliced ​​stretcher, when inserted under the body of a spinal patient using manpower, is very likely to cause twisting and bending of the spine, and the degree of twisting and bending often exceeds the medically permitted range. At the same time, it is difficult to ensure the urgency of the treatment using simple manpower, so conventional rescue stretchers are not suitable for seriously injured spinal patients. Summary of the Invention

[0004] In view of the above problems, the purpose of the present invention is to provide a splicing-type posture-small-disturbance picking-up stretcher, so as to effectively reduce the posture disturbance of the wounded during the picking-up process, thereby avoiding secondary injury to the spinal wounded.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A plug-in type posture small disturbance picking stretcher comprises a picking cabin, a temporary stretcher, a linear module and mechanical arms, wherein the temporary stretcher is inserted at the bottom of the picking cabin, the linear module is arranged at the top of the picking cabin, and the mechanical arms are suspended on the linear module; the mechanical arms are used to hold the wounded, and are convenient for inserting or extracting the temporary stretcher at the bottom of the picking cabin.

[0007] The temporary stretcher is formed by sequentially plugging together a plurality of pull-out panels.

[0008] One side of the plug-in panel is provided with a guide rail, and the other side is provided with a guide groove; the guide rail of one plug-in panel is plugged into the guide groove of another adjacent plug-in panel.

[0009] A conical guiding structure is provided at the rear end of the guide rail.

[0010] A slot is provided at the bottom of the picking cabin, and the plug-in puzzle board is inserted into the slot.

[0011] The front end of the picking cabin is provided with a plurality of anti-falling spring lock mechanisms; the front end of the plug-in puzzle board is provided with a lock hole; when the plug-in puzzle board is inserted into the slot at the bottom of the picking cabin, the lock hole at the front end of the plug-in puzzle board cooperates with the corresponding anti-falling spring lock mechanism to limit the plug-in puzzle board.

[0012] The anti-fall-off spring lock mechanism includes a lock nose, a spring and a lock seat, wherein the lock seat is a hollow structure, the lower end of the lock nose is inserted into the lock seat, and an axial limit is provided at the end by a shaft shoulder; the spring is accommodated in the lock seat, and the upper end abuts against the lower end of the lock nose, so that the upper end of the lock nose extends out of the lock seat.

[0013] A front handle is provided at the front end of the plug-in puzzle board, and the front handle is located on the outside of the lock hole.

[0014] A rear rib is provided at the bottom of the rear end of the pulling and inserting panel.

[0015] The picking ends of the mechanical double arms are arc-shaped shovels.

[0016] The present invention has the following beneficial effects and advantages:

[0017] 1. The temporary stretcher of the present invention has its own guide grooves at both ends. The two adjacent panels serve as guide rails for each other to ensure smooth insertion and extraction, convenient operation and tight combination. Moreover, since the guide rails are attached to both ends of the panels, it can be ensured that after the extraction or insertion process is completed, the wounded can directly separate and combine with the temporary stretcher with ease.

[0018] 2. The present invention uses mechanical arms to hold the human body, which can also prevent medical staff from using different strengths and weaknesses on different people.

[0019] 3. The present invention ensures that the patient's dorsiflexion and hyperextension are within the specified range through the thickness of the panels and the lifting height of the mechanical arms. The whole process can effectively reduce the disturbance to the patient's posture during the picking up process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 As shown, the present invention provides a plug-in type posture small disturbance picking stretcher, which includes a picking cabin 1, a temporary stretcher 2, a linear module 3 and a mechanical arm 4, wherein the temporary stretcher 2 is inserted at the bottom of the picking cabin 1, the linear module 3 is arranged at the top of the picking cabin 1, and a group of mechanical arms 4 are suspended on the linear module 3; the mechanical arms 4 are used to hold the wounded 5, which is convenient for inserting or extracting the temporary stretcher 2 at the bottom of the picking cabin 1; the linear module 3 is used to adjust the position of the mechanical arms 4.

[0032] like Figure 2-3 As shown, in the embodiment of the present invention, the temporary stretcher 2 is formed by a plurality of plug-in panels 6 that are sequentially plugged in. The plug-in panels 6 can be plugged in and out at will, and are easy to assemble and disassemble.

[0033] like Figure 4-5 As shown, in the embodiment of the present invention, a guide rail 7 is provided on one side of the pull-in puzzle board 6, and a guide groove 8 is provided on the other side; the guide rail 7 of one pull-in puzzle board 6 is plugged into the guide groove 8 of another adjacent pull-in puzzle board 6.

[0034] Furthermore, in order to facilitate the mutual insertion of the two plug-in panels 6, a conical guiding structure 10 is provided at the rear end of the guide rail 7. Figure 7The conical guide structure 10 serves as a guide during insertion and withdrawal to ensure smooth insertion and withdrawal.

[0035] Furthermore, a front handle 9 is provided at the front end of the plug-in panel 6 , and a lock hole 15 is provided on the inner side of the front handle 9 , and the plug-in panel 6 is pushed and pulled by the front handle 9 .

[0036] like Figure 6-7 As shown, a rear end bottom of the pull-out panel 6 is provided with a rear retaining edge 11, which is used to limit the push-pull stroke of the pull-out panel 6 to prevent it from detaching from the picking cabin 1 when pulled out. The rear retaining edge 11 also serves as a limit when the pull-out panel 6 is inserted into its original position at the bottom of the cabin.

[0037] like Figure 8-9 As shown, in the embodiment of the present invention, a slot is provided at the bottom of the picking cabin 1, into which the pull-out panel 6 is inserted. A plurality of anti-dropping spring lock mechanisms are provided at the front end of the picking cabin 1. When the pull-out panel 6 is inserted into the slot at the bottom of the picking cabin 1, the lock holes 15 at the front end of the pull-out panel 6 cooperate with the corresponding anti-dropping spring lock mechanisms to limit the pull-out panel 6.

[0038] In an embodiment of the present invention, the anti-fall-off spring lock mechanism includes a lock nose 12, a spring 13 and a lock seat 14, wherein the lock seat 14 is a hollow structure, the lower end of the lock nose 12 is inserted into the lock seat 14, and an axial limit is provided by a shoulder at the end; the spring 13 is accommodated in the lock seat 14, and the upper end abuts against the lower end of the lock nose 12, so that the upper end of the lock nose 12 extends out from the lock seat 14.

[0039] In an embodiment of the present invention, the travel of the linear module 3 is substantially equal to the height of a human body. The linear module 3 drives the mechanical arms 4 to different locations on the patient. The pick-up ends of the mechanical arms 4 are curved scoops, making it easier to lift the patient. Medical personnel are responsible for the simple insertion and removal of the panels 6. Once all panels 6 are removed, the pick-up cabin 1 can cover the patient 5. Driven by the linear module 3, the mechanical arms 4 lift the patient 5 from head to toe to a certain height. At the same time, the medical personnel sequentially insert all the panels 6 back into their original positions on the cabin floor, transferring the patient from the ground to the temporary stretcher 2.

[0040] Repeat the lifting and drawing action again to complete the transfer of the wounded from the temporary stretcher 2 to the transport stretcher.

[0041] In the embodiment of the present invention, a front handle 9 is provided at the front of the pull-out panel 6 for medical personnel to place their fingers, and a spring-lock mechanism is provided at the bottom of the front handle. When the front handle 9 is grasped, the fingers will be inserted into the lock hole 15 inside the front handle 9, pressing the lock nose 12, so that the lock nose 12 is disengaged from the lock hole 15, and the pull-out panel 6 can be smoothly withdrawn. When the pull-out panel 6 is inserted into its original position at the bottom of the cabin, the lock nose 12 is ejected by the spring 13 and inserted into the lock hole 15, preventing the pull-out panel 6 from falling out during use.

[0042] A rear retaining edge 11 is provided on the rear part of the back of the plug-in panel to prevent the medical staff from detaching from the picking cabin 1 when pulling out the plug-in panel 6. The rear retaining edge 11 also serves as a limit when the medical staff inserts the plug-in panel 6 into its original position at the bottom of the cabin.

[0043] The present invention provides a modular temporary stretcher suitable for severely injured spinal patients. Using dual manipulators, the patient is lifted and lowered from head to toe, one by one, while meeting medical safety requirements. The patient is first transferred from the ground to the temporary stretcher and then from the temporary stretcher to a transport stretcher. During this process, spinal rotation, displacement, and hyperflexion, as required by medical safety requirements, are maintained, minimizing the risk of secondary injury to spinal injury survivors due to changes in spinal position, including those in the head, neck, and waist.

[0044] The above description is only an embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modification, equivalent replacement, improvement, expansion, etc. made within the spirit and principle of the present invention are included in the scope of protection of the present invention.
