Abstract
The invention is a medical device implanted into a body. The medical device is used when surgical treatment is carried out on a hydrocephalic patient in the neurosurgery department. When the hydrocephalic patient is attacked, excessive cerebrospinal fluid in the skull needs to be shunted to the abdominal cavity to relieve adverse reaction caused by intracranial hypertension and maintain the intracranial pressure suitable for the patient, and therefore the treatment effect is achieved. According to a method for controlling the capacity of a cerebral ventricle and abdominal cavity shunt device, an elastic material is adopted for making a non-pressure liquid storage bag, the two ends of the liquid storage bag are provided with two one-way valves, and the liquid storage bag is manually pressed so that the cerebrospinal fluid can flow to the abdominal cavity end to control the capacity of the cerebrospinal fluid in the liquid storage bag. A capacity control type cerebral ventricle and abdominal cavity shunt tube achieving the method for controlling the capacity of the cerebral ventricle and abdominal cavity shunt device is provided with the liquid storage bag made of the elastic material, the two ends of the liquid storage bag are provided with the two one-way valves same in direction, and the volume of the liquid storage bag is 2-6ml. After the operation is performed on the hydrocephalic patient, pressing of the proper number of times can be carried out each day according to needs, and the proper amount of the cerebrospinal fluid is shunted into the abdominal cavity, so that clinical cure is achieved.
Description
Technical field
The present invention is a kind of medical apparatus when belonging to hydrocephalic and performing the operation.Belong to medical instruments field.
Background technology
Isocon device used when hydrocephalic carries out shunt operation carries out with pressure control at present, there are two types of fixation pressure and adjustable pressures, but clinically often because the pressure selection of part flow arrangement is improper, or because people's position and activity, the fluctuation of intracranial pressure and patient's individual reason, use pressure-adjustable part flow arrangement, often also there will be the excessive drain of cerebrospinal fluid, cause operative treatment failure, need readjust operation, some patients operative failure even repeatedly.
Simultaneously, no matter be the controllable isocon device of fixation pressure or pressure, reservoir volume is 1 milliliter of left and right, material adopts pressure-bearing material, overall volume is little, and two ends one-way valve opens is subject to the control of reservoir internal pressure to open voluntarily discharge cerebrospinal fluid, guarantee functional reliability, manufacturing technology requires very high, and product cost is higher.
At present, the shunt device of cerebrospinal fluid for the treatment of clinically hydrocephalus operation use is mainly pressure control, has two types of fixation pressure and adjustable pressures.Fixation pressure isocon need carry out accurate assessment to patient's intracranial pressure in the preoperative, and slightly deviation will cause operative failure; Pressure-adjustable part flow arrangement at present application is more extensive, postoperatively can adjust pressure according to patient's symptom and intracranial pressure situation.Even like this, because the activity of people's position, intracranial fluctuation and individual patients reason etc. often also there will be the excessive drain of cerebrospinal fluid, cause operative treatment failure, need readjust operation, some patients operative failure even repeatedly.
Summary of the invention
(1) goal of the invention
A kind of volume control type ventricles of the brain peritoneal shunt device, can effectively prevent the excessively problem of shunting of hydrocephalus pressure control isocon.
(2) technical scheme
Ventricles of the brain peritoneal shunt installed capacity control method, it adopts elastomeric material to make stress-free reservoir, and two one-way cocks are established at reservoir two ends, make csf flow to cerebrospinal fluid capacity in abdominal end control reservoir by manually pressing reservoir.
Realize the volume control type ventricles of the brain peritoneal shunt pipe of described ventricles of the brain peritoneal shunt installed capacity control method, it has a reservoir that adopts elastomeric material to make, and two check valves that direction is identical are equipped with at these reservoir two ends, and reservoir volume is at 2-6ml.
The present invention is in order to solve this problem of pressure control isocon, a kind of volume control ventricles of the brain peritoneal shunt device of design, after operation in patients by according to oneself symptom and the secreting law of cerebrospinal fluid, make rational cerebrospinal fluid discharge capacity, give suitable pressing, make unnecessary cerebrospinal fluid flow into abdominal end, carry out volume control shunting, can not cause excessive drain.Particularly the present invention adopts the reservoir volume of elastomeric material making at 2-6ml, volume expands greatly than existing product volume, automatically control check valve folding without adopting existing pressure control structure, require greatly to reduce so manufacture, only need to adopt common medical elastic transparent material to make, patient or doctor completely can press voluntarily and discharge unnecessary hydrops according to secretory volume, not only can not cause excessive drain, and product cost reduce greatly.
Accompanying drawing explanation
Fig. 1 is volume control type ventricles of the brain peritoneal shunt tubular construction schematic diagram of the present invention.
The specific embodiment
Ventricles of the brain peritoneal shunt installed capacity control method, it adopts elastomeric material to make stress-free reservoir, and two one-way cocks are established at reservoir two ends, make csf flow to cerebrospinal fluid capacity in abdominal end control reservoir by manually pressing reservoir.
As shown in Figure 1, realize the volume control type ventricles of the brain peritoneal shunt pipe of described ventricles of the brain peritoneal shunt installed capacity control method, it has a reservoir that adopts elastomeric material to make, and two check valves that direction is identical are equipped with at these reservoir two ends, and reservoir volume is at 2-6ml.
Described isocon is divided into head end isocon (Fig. 1 left end tube head), centre is reservoir 2 and abdominal end isocon (right-hand member tube head in figure) three parts, reservoir volume 5ml, can be connected with head end and abdominal end isocon, reservoir 2 two ends have one-way cock 1(as shown in Figure 1 check valve open consistent with direction), guarantee that cerebrospinal fluid only flows to abdominal end (right-hand member in Fig. 1) while pressing blister cavities.When operation, reservoir is put into before thoracic wall, so that postoperative handled easily makes reservoir be connected with ventricles of the brain end isocon and abdominal end isocon.
Claims (2)
1. ventricles of the brain peritoneal shunt installed capacity control method, is characterized in that adopting elastomeric material to make stress-free reservoir, and two one-way cocks are established at reservoir two ends, makes csf flow to cerebrospinal fluid capacity in abdominal end control reservoir by manually pressing reservoir.
2. realize the volume control type ventricles of the brain peritoneal shunt pipe of ventricles of the brain peritoneal shunt installed capacity control method as claimed in claim 1, it is characterized in that having a reservoir (2) that adopts elastomeric material to make, two check valves (1) that direction is identical are equipped with at this reservoir (2) two ends, and reservoir (2) volume is at 2-6ml.
