Description
Technical field
This utility model belongs to technical field of medical equipment, relates to a kind of medical apparatus and instruments, especially a kind of easy and simple to handle, fully can ensure patient's freedom of action, observe adjust blood pressure the next (thoracic wall) ventriculo-peritoneal shunt pipe of regulating easily.
Background technology
The ventricles of the brain-peritoneal shunt device is widely used in treating hydrocephalus, and the liquid storage pressure-regulating valve in existing part flow arrangement is positioned at upper, is namely positioned at head.Because head is circular or oval, and existing pressure-regulating valve is accurate in order to pressure, when regulating pressure, require that health and pressure-regulating valve will keep horizontal position, therefore, the problem of existing shunt device of cerebrospinal fluid common following several respects when doctor's practical operation:
1, patient will certainly be caused during adjust blood pressure to stand up, move not only inconvenience but also there is risk particularly to coma patient.
2, be through frontal eminence or cornu occipitale because the length of pressure-regulating valve determines ventricular puncture, so when performing an operation, different isocons will be selected according to site of puncture, and the product quality of different manufacturers, model is all different.Which adds the trouble that doctor selects.
3, postoperative patient often will press reservoir, if reservoir is placed on head, close on cephalic incision, frequent pressing can cause incision pain and infection, larger problem is that patient oneself is difficult to cosily operate adjust blood pressure reservoir, and the inconvenience caused to recognize reservoir position often to move head and risk.
If invent a kind of bottom being convenient to patient oneself operation to regulate ventriculo-peritoneal shunt device, the selection neither allowing doctor be entangled with during impact operation is inserted from frontal eminence or cornu occipitale, patient and freedom of action is moved after not affecting implantation surgery again, more convenient patient oneself can adjust blood pressure at any time, has great clinical meaning.
By retrieval, find following several sections of patent publication us relevant to this utility model patent application:
1, a kind of ventricles of the brain-abdominal cavity shunt device of cerebrospinal fluid (203970988U), this part flow arrangement comprise one for insert the subcutaneous external water capsule of abdominal cavity of patients and one for by ICV drainage of cerebrospinal fluid to the conduit in abdominal cavity, the outer wall of described conduit is arranged with one for water pocket in extruded conduit, interior water pocket is communicated with external water capsule by water injection pipe, and water injection pipe is provided with the check valve for liquid in external water capsule being introduced interior water pocket, described interior water pocket is provided with one for discharging the liquid pumping hole of liquid in its inner chamber, this liquid pumping hole seals for the silica gel sealing pad thrusting liquid pumping needle by one.This part flow arrangement in use, medical personnel are through external extruding external water capsule, can by the water pocket in water injection pipe injects of the liquid in external water capsule, interior water pocket expands and the catheter diameter of its sandwiched is reduced, thus the drainage flow of cerebrospinal fluid in adjustment conduit, there is good clinical safety, meet the circulating pressure needs of cerebrospinal fluid.
