Description

Technical Field

[0001] The invention relates to the field of medical technology, in particular to a novel spinal cord injury transport model. Background Art

[0002] The cervical spine refers to the cervical vertebrae, which are located below the head and above the thoracic spine. There are 7 vertebrae located in the cervical spine, which surround the cervical cord and its spinal meninges. They are connected by intervertebral discs and ligaments, forming a physiological curvature that convexes forward. The characteristics of the cervical spine are that the vertebral body is small and oval, with transverse foramina on the transverse processes, through which the vertebral artery and vertebral vein pass; the spinous processes are short and bifurcated; the joints of the upper and lower articular processes are approximately horizontal, allowing the neck to move flexibly. The upper and lower notches of adjacent vertebrae form intervertebral foramina, through which spinal nerves and blood vessels pass. The transport model is needed when training medical students and emergency medical personnel to transport and fix patients with spinal cord injury. However, the existing spinal cord injury models have only one joint in the neck, which does not simulate the real structure of the cervical spine, and only have one-way movement, flexion forward and backward, which does not conform to the changes in cervical fracture cases. When using it, it can only judge whether the trainees' transport and fixation techniques are correct, and it is impossible to intuitively judge the fixation and transport quality. For this reason, we propose a new spinal cord injury transport model. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of spinal cord injury transportation model with the advantage of alarm, which solves the problem that the existing spinal cord injury models only have one joint in the neck, fail to simulate the real structure of the cervical spine, and only have one-way movement, forward and backward flexion, which does not conform to the case changes of cervical fractures. When in use, it can only judge whether the trainee's transportation and fixation techniques are correct, but cannot intuitively judge the fixation and transportation quality.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel spinal cord injury transport model, comprising a cervical vertebra body and a model body, a buzzer is welded on the top of the model body by a thermoplastic process, a battery is embedded in the upper end of the inner cavity of the model body, the input end of the battery is electrically connected to an external USB interface, a through hole is opened at the middle end of the model body, an anti-slip cover is provided on the inner wall of the through hole, a cervical vertebra body is provided on the inner wall of the anti-slip cover, a pipe is provided on the inner side of the anti-slip cover and located on the inner side of the cervical vertebra body, the top of the pipe is electrically connected to a pressure sensor through a power cord, and the bottom of the pressure sensor is welded to the inner cavity of the model body.

[0005] Preferably, the cervical vertebra body includes a first vertebra, a second vertebra, a third vertebra, a fourth vertebra, a fifth vertebra, a sixth vertebra and a seventh vertebra.

[0006] Preferably, gaps are formed between the first vertebra, the second vertebra, the third vertebra, the fourth vertebra, the fifth vertebra, the sixth vertebra and the seventh vertebra.

[0007] Preferably, the first, second, third, fourth, fifth, sixth and seventh vertebrae are filled with a first solid filler, a second solid filler, a third solid filler, a fourth solid filler and a fifth solid filler respectively.

[0008] Preferably, the surfaces of the first solid filler, the second solid filler, the third solid filler, the fourth solid filler and the fifth solid filler are connected with silicone rubber through a thermoplastic process, and the outer surface of the silicone rubber is in close contact with the inner surfaces of the first vertebra, the second vertebra, the third vertebra, the fourth vertebra, the fifth vertebra, the sixth vertebra and the seventh vertebra.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention provides a pipe on the inner side of the anti-slip sleeve and located on the inner side of the cervical vertebra body, and the top of the pipe is electrically connected to a pressure sensor through a power line. When the cervical vertebra is not well fixed during transportation, resulting in excessive movement in any direction, the pressure in the pipe exceeds the sensor threshold, and the pressure sensor alarms, which has the effect of automatic alarm. A buzzer is welded on the top of the model body through a thermoplastic process, which has the effect of a buzzer alarm, and solves the problem that the existing spinal cord injury model has only one joint in the neck, does not simulate the real structure of the cervical vertebra, and has only one-way movement, front and back flexion, which does not conform to the case changes of cervical fracture. When in use, it can only judge whether the trainee's transportation and fixation method is correct, and cannot intuitively judge the problem of fixation and transportation quality.

The first vertebra 2, the second vertebra 3, the third vertebra 4, the fourth vertebra 5, the fifth vertebra 6, the sixth vertebra 7 and the seventh vertebra 8 are respectively filled with a first solid filler 9, a second solid filler 10, a third solid filler 11, a fourth solid filler 12 and a fifth solid filler 13. The surfaces of the first solid filler 9, the second solid filler 10, the third solid filler 11, the fourth solid filler 12 and the fifth solid filler 13 are connected with silicone rubber through a thermoplastic process, and the outer surface of the silicone rubber is in close contact with the inner surfaces of the first vertebra 2, the second vertebra 3, the third vertebra 4, the fourth vertebra 5, the fifth vertebra 6, the sixth vertebra 7 and the seventh vertebra 8.

[0020] When in use, the cervical vertebra body 1 includes the first vertebra 2, the second vertebra 3, the third vertebra 4, the fourth vertebra 5, the fifth vertebra 6, the sixth vertebra 7 and the seventh vertebra 8, which has the effect of restoring the bony structure of the cervical vertebra, and the first solid filler 9, the second solid filler 10, the third solid filler 11, the fourth solid filler 12 and the fifth solid filler 13 are placed between the cervical vertebra body 1 including the first vertebra 2, the second vertebra 3, the third vertebra 4, the fourth vertebra 5, the fifth vertebra 6, the sixth vertebra 7 and the seventh vertebra 8, so that the cervical vertebra body 1 can simulate normal flexion and extension, lateral flexion and rotation, and each fixing material can be removed.
