This invention belongs to the field of animal model technology, specifically disclosing a method for constructing a primary ciliary motor disorder hydrocephalus model, comprising the following steps: screening benzimidazole as a modeling agent; administering benzimidazole solution to experimental animals and setting up a blank control group; conducting experimental verification through pathological morphology and behavioral methods; if the experimental animals show significant ventricular enlargement and significant decrease in motor ability, the primary ciliary motor disorder hydrocephalus model is successfully constructed. This invention employs the above-mentioned novel method for constructing a primary ciliary motor disorder hydrocephalus model. The constructed hydrocephalus model exhibits good stability and repeatability, is objective and simple, and is highly operable, reducing other possible interfering factors. It provides a necessary experimental foundation for studying the mechanism of primary ciliary motor disorder hydrocephalus and developing treatment methods.

The utility model relates to medical instrument technical field especially a ventricular peritoneal shunt pass bar. The utility model discloses pass bar subassembly, handle, guide piece and shunt tube fixed subassembly, pass bar subassembly includes the pass bar body of being placed in the patient's skin and the installation sleeve of being fixed in the pass bar body front end end portion, shunt tube fixed subassembly includes the installation post of being detachably installed in the inside of installation sleeve, the disc that is fixed in the installation post front end end face and with installation sleeve front end end face abuts and the plug rod of rotating being arranged in the disc front disc surface middle part and being inserted in the shunt tube spout, the guide piece detachably sets up in the installation sleeve outside, the handle is fixed in the pass bar body rear end. The device can reduce the external diameter of pass bar subassembly whole under the condition of keeping the shunt tube diameter invariable to reduce the injury to the child when puncturing.

This invention relates to the field of medical device technology and discloses a fixation device for an external ventricular drainage tube and an intracranial pressure probe, including a side plate and a top plate. An adjustment assembly is provided between the side plate and the top plate, and a fixation mechanism is provided on the outer side of each side plate and the top plate. This invention secures the device to the patient's head by fastening the fixation sleeve formed by the side plate and the top plate to the outside of the patient's head. Then, the first and second fixation straps are pulled and secured using the round and barbed surfaces of the Velcro. The fixation is convenient and quick. The breathable padding improves the comfort and breathability of the device after fixation, preventing discomfort or allergic reactions caused by stuffiness. Furthermore, during fixation, adjustments can be made by pulling the two sets of side plates, allowing the limiting rod to move within the cavity, thus facilitating adjustment of the fixation sleeve size. This allows for adjustment according to the patient's head size, resulting in high applicability.
