DETAILED DESCRIPTION

[0027] The present application will be further described below with reference to the drawings.

[0028] Referring to Figures 1-3 , the emergency fracture patient moving device of the present embodiment mainly includes a stretcher assembly 1 and a connecting assembly 2.

[0029] In the embodiment, the stretcher assembly 1 is provided with two symmetrical ones. Each of the stretcher assembly 1 comprises a support tube 11 and a support plate 12. The support tube 11 is composed of a tube vertical segment 111 extending front to back, and a tube horizontal segment 112 connected to the front and back ends of the tube vertical segment 111 and extending laterally in the same direction. The support plate 12 is connected to the side of the tube vertical segment 111 and extends in the same direction as the tube horizontal segment 112. The unique structure design allows the two stretcher assemblies 1 to be easily inserted from both sides of the patient's body, so that the patient can be placed on the stretcher assembly 1 without turning over, thereby greatly reducing the possibility of secondary injury.

[0030] In the embodiment, the connecting assembly 2 is also provided with two, which functions to lock and connect with the two groups of tube horizontal segments 112 when the two stretcher assemblies 1 are relatively combined, thereby stably connecting the two stretcher assemblies 1 into one whole, ensuring the stability of the patient during movement.

[0031] In the embodiment, the connecting assembly 2 comprises a connecting tube 21, a locking member 22 and an elastic member 23.

[0032] In the embodiment, the connecting tube 21 is composed of a tube large diameter segment 211 and a tube small diameter segment 212. The two tube small diameter segments 212 are respectively connected to the two ends of the tube large diameter segment 211 for insertion into the tube horizontal segment 112 to achieve axial connection with the tube horizontal segment 112.

[0033] In the embodiment, the locking member 22 has two, which are symmetrically and radially slidingly connected in the connecting tube 21. The locking member 22 extends along the axis direction of the connecting tube 21, and both ends thereof are provided with a locking block 221 radially penetrating the same side tube small diameter segment 212. In addition, the tube horizontal segment 112 is provided with a lock hole 1121 corresponding to the locking block 221, and when the locking block 221 is clamped into the lock hole 1121, the locking of the connecting tube 21 and the tube horizontal segment 112 is achieved, that is, the axial positioning is achieved to prevent the connecting tube 21 from being axially pulled out of the tube horizontal segment 112.

[0034] In the embodiment, the elastic member 23 is used to push the two locking members 22 to the opposite sides respectively, so that the locking block 221 can be smoothly clamped into the lock hole 1121 to complete the locking of the connecting tube 21 and the tube horizontal segment 112. In order to facilitate the user to operate the locking member 22, a clearance slot 2111 is formed in the tube large diameter segment 211, and the user can push the locking member 22 radially through the clearance slot 2111 to achieve unlocking.

[0035] Further, in the embodiment, the opposite sides of the two locking blocks 221 of the same locking member 22 are respectively provided with guide inclined surfaces 2211. When the end of the pipe transverse section 112 abuts against the guide inclined surface 2211, the locking block 221 is pushed to slide radially inward on the pipe large-diameter section 211, so that the connecting pipe 21 can be more easily inserted into the pipe transverse section 112. Thus, when the pipes are locked, the user does not need to pinch the locking member 22, greatly improving the convenience of the connecting operation.

[0036] In the embodiment, the connecting pipe 21 is fixedly connected with radially extending slide rods 213, and the locking member 22 is slidingly assembled on the slide rods 213 through slide holes. The slide rods 213 provide accurate guidance for the sliding of the locking member 22, ensuring the stability and accuracy of the sliding of the locking member 22. To further improve the stability, two slide rods 213 are axially spaced apart in the connecting pipe 21.

[0037] In the embodiment, the elastic member 23 adopts a coil spring 231. The coil spring 231 is sleeved outside the slide rod 213, and the two ends thereof respectively abut against the two locking members 22, so that the coil spring 231 can continuously and stably provide a pushing force for the locking member 22, ensuring the reliable locking of the locking block 221 and the lock hole 1121.

[0038] In the embodiment, the slide rod 213 and the pipe large-diameter section 211 are connected in a detachable manner. The two ends of the slide rod 213 penetrate through the pipe large-diameter section 211 and are connected with limiting nuts 2131 through threads. This design makes the installation and dismounting of the slide rod 213 very convenient, facilitating the maintenance and replacement of components in the later period.

[0039] In the embodiment, the two letting-in grooves 2111 correspond to the positions of the two locking members 22, facilitating the operation of the locking member 22 by the user. To improve the pinching feeling of the locking member 22, the edges of the letting-in grooves 2111 are fixedly connected with soft sleeves 2112 that close the letting-in grooves 2111. When the locking member 22 is pushed, the user can pinch the soft sleeves 2112 on both sides to push the locking member 22 on both sides through the soft sleeves.

[0040] Assembly process:

[0041] Pre-connection operation: when used, the two connecting assemblies 2 are respectively connected with one of the stretcher assemblies 1. Specifically, the pipe small-diameter section 212 of the connecting assembly 2 is aligned with the port of the pipe transverse section 112 of the stretcher assembly 1 and is inserted, the end of the pipe transverse section 112 abuts against the guide inclined surface 2211 of the locking block 221, and the locking block 221 is pushed to slide radially inward on the pipe large-diameter section 211. When the locking block 221 is aligned with the lock hole 1121 of the pipe transverse section 112, the locking block 221 is clamped into the lock hole 1121 under the pushing force of the coil spring 231, and the locking of the connecting assembly 2 and the stretcher assembly 1 is completed.

[0042] Inserting the stretcher assembly: when it is necessary to move a fractured patient, the pre-connected stretcher assembly 1 and another stretcher assembly 1 are smoothly inserted from the left and right sides of the patient, ensuring that the patient is located between the two stretcher assemblies 1. During this process, the patient does not need to be turned over and always remains in a flat position, effectively avoiding secondary injury.

[0043] Completing the connection of the stretcher assembly: the other end pipe small diameter section 212 of the connection assembly 2 pre-connected on the stretcher assembly 1 on one side is inserted into the pipe horizontal section 112 of the stretcher assembly 1 on the other side. The end of the pipe horizontal section 112 abuts against the guide inclined surface 2211 of the lock block 221, the lock block 221 is pushed to slide radially inward, and when the lock block 221 is aligned with the lock hole 1121, the locking is completed under the action of the helical spring 231, and the device is assembled into a stable whole.

[0044] Disassembly process:

[0045] When it is necessary to separate the two stretcher assemblies 1, the user uses both hands to pinch the soft sleeve 2112 of the let-in groove 2111 on both sides of the connection pipe 21. The soft sleeve 2112 not only improves the pinching feeling, but also increases the friction between the hands and the connection pipe 21. By pinching the soft sleeve 2112 and applying force inward, the locking part 22 is driven to move radially in the pipe large diameter section 211, so that the lock block 221 is separated from the lock hole 1121. At this time, the connection pipe 21 can be pulled out of the pipe horizontal section 112. According to the same steps, the locking of all connection assemblies 2 and the pipe horizontal sections 112 of the stretcher assemblies 1 on both sides is released, and the two stretcher assemblies 1 are smoothly separated, and the disassembly operation is completed.

[0046] The utility model discloses a kind of emergency fracture patient moving devices, and it is significantly advantageous in aspects such as guaranteeing patient safety, improving operation efficiency and reducing maintenance cost. In patient safety guarantee, the unique stretcher assembly 1 of device can be directly inserted from both sides of patient, avoid turning over patient, effectively reduce secondary injury risk. Operation level, the guide inclined surface 2211 design of connection assembly 2, let connection process be completed automatically, do not need to be artificially pinched locking part 22, greatly improve installation convenience;And the design of let-in groove 2111 and soft sleeve 2112, optimization disassembly experience.In addition, device uses modular design, stretcher assembly 1 and connection assembly 2 are independent and closely cooperate each other, not only facilitate production and manufacture, reduce production cost, also facilitate later maintenance, by replacing damaged module, such as using limit nut 2131 to replace sliding rod 213, reduce maintenance difficulty and cost, prolong the service life of device.
