Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and more particularly to a human body fixation device suitable for lumbar puncture of children. Background Art

[0002] Lumbar puncture is a common diagnostic and therapeutic method, often used for cerebrospinal fluid examination, drug injection and treatment of certain neurological diseases (such as abnormal intracranial pressure, central nervous system infection, etc.). Before lumbar puncture, the patient usually takes a side-lying position with the back perpendicular to the bed surface, the head forward and the chest flexed, the hands hugging the knees close to the abdomen, and the overall trunk in an arched shape. This posture helps to widen the intervertebral space and facilitate needle insertion. However, children need special attention during lumbar puncture due to their smaller size and sensitivity to pain. The non-cooperation of children increases the workload of assistants, which ultimately leads to low puncture efficiency and difficulty in achieving aseptic operation.

[0003] There are few existing lumbar puncture fixation devices for children, which are mainly divided into two categories: one is wearable, where the patient wears a restraint or straps, and adjusts the length and tightness of the device to make the limbs and trunk form a fixed angle. However, this type of device requires the patient to actively cooperate, and it is difficult to fix the patient's arms, especially the forearms. When children feel uncomfortable in the lumbar puncture posture, they are prone to pulling or breaking free from the restraints, and still need the assistance of an assistant.

[0004] The second is the bed type, that is, the device is connected to the bed, and the lumbar spine is exposed and stretched by adjusting and fixing the patient's posture. However, this type of device often only restrains the patient's upper limbs, and its restraint effect is poor. The human body still has a large degree of mobility. During the clinical process, children's fear will cause struggle, making it difficult to achieve the fixation effect. Summary of the invention
