CN2314807Y - Sac for ventricular drainage therapeutic use - Google Patents

Abstract

The utility model relates to a sac for ventricular drainage and therapy, belonging to a medicine appliance for ventricular drainage and medicine pouring therapy. The utility model is composed of a ball-shaped liquid storing sac (1) made of silicone rubber and a guiding tube for inserting in the ventricle. Both ends of the guiding tube are horizontal guiding tubes (3), and one end of the guiding tube is connected with a connecting tube (2). The utility model has the advantages of simple structure, convenient manufacture and convenient use. Intracranial pressure is rapidly reduced during drainage, a symptom of increased intracranial pressure is released, and implantation of cancer cells is reduced. Pain of repeated LP or ventricular puncture is avoided, all medicine is ensured to enter a central nervous system, tumor cancer cells are directly restrained or killed, and the best benefit of medicine is exerted.

Description

Ventricular drainage treatment capsule

This utility model belongs to ventricular drainage and treatment of drug perfusion medical instruments.

Meningeal carcinomatosis is that malignant tumor diffusivity or many kitchen ranges property meninges shift, and is one of lethal major reason of malignant tumor.Because the raising of cerebrospinal fluid cytologic diagnosis technology now realizes prenatal diagnosis substantially.Because the prolongation of general tumour patient survival period and people are to the raising of this complication understanding, its incidence rate has the trend that increases year by year.According to the literature, the natural history of primary disease only is 4-6 week.At present domestic primary disease is only limited to the research of diagnosis aspect, still do not have the report of treatment aspect.External used apparatus is the ommaya capsule, and it is "T"-shaped structure (Fig. 2).Because vertical tube directly joins with ventricular drainage tube, the attaching difficulty, pipe range gives a discount easily, then is difficult to butt joint if be of convenient length, and takes off pipe easily, causes the treatment accident, too shortly then easily deviates from the ventricles of the brain, causes device to fail.

The purpose of this utility model is that the ommaya capsule of T-shape structure is improved, and makes horizontal shape drainage tube, is convenient to operation, avoids drainage tube to deviate from, and guarantees that drain is unobstructed, reduces complication.

The treatment of a kind of ventricular drainage is characterized in that with capsule it is horizontal shape conduit [3] that sphere that silicone rubber is made is held liquid capsule [1] two ends, and it is used to insert an end of the ventricles of the brain, the conduit that connects through connection tube [2].

Using method of the present utility model is to hole at frontal bone earlier, import ventricular drainage tube, the oblique bone groove of conduit through making is connected with main part, this main part is inserted in the hemispheric skull depression, outer catheter connects the other end of capsule, pass scalp and be connected with brain drainage bottle, capsule is semifixed state between scalp and skull.

But this device drainage of cerebrospinal fluid reduces intracranial pressure, and gets specimen and do relevant chemical examination, checks and can inject medicine through conduit.When treating to the stabilization sub stage, outer catheter can be cut off the back in the ligation of nearly capsule place and enclose in the scalp.At this moment, but patient's ambulation, the hardship of minimizing long-term bed.When needing, available syringe punctures through scalp, extracts cerebrospinal fluid chemical examination, drain and injectable drug (Fig. 3) from capsule.The medicine that holds in the liquid capsule can be pushed the injection ventricles of the brain (Fig. 4) through scalp.

Function of the present utility model has: 1, make the CSF external drainage through this device, can reduce intracranial pressure, alleviate intracranial and increase symptom such as headache, vomiting, disturbance of consciousness, epilepsy etc.With the CSF drain, part tumor cell and immune inflammation material are excreted, and reduce the stimulation to CSF lacuna (ventricles of the brain, brain pond, subarachnoid space etc.), thereby alleviate the meningeal irritation symptom, have also reduced " plantation " of cancerous cell simultaneously.2, through this device, the perfusion of row ventricles of the brain chemotherapeutics, medicine can arrive whole CSF lacunas with the mobile regular path of CSF, the optimum effect of performance medicine, the method is better than intrathecal chemotherapy.Because of latter's medicine injects under the dura mater or epidural space through constant error, can not form effective drug level at tumor locus, also be difficult to arrive ventricular system.3, can take the CSF specimen to do relevant laboratory examination through this device at any time, as CSF routine, biochemistry, cytology, immunology, cultivation, pharmacokinetics experimental check etc.4, but this device long period is used, and behind sb.'s illness took a favorable turn the ligation drainage tube, but patient's ambulation reduces the worries of long-term bed; In case the state of an illness needs, percutaneous puncture holds inspection and the treatment that the liquid capsule is correlated with at any time, avoids repeatedly the hardship of the LP or the ventricles of the brain (pond) puncture.5, this device also is applicable to Intraventricular treatment, the bullate drain of internal capsule of brain of the various chronic meningitiss that do not heal for a long time, more is applicable to the treatment of meningeal leukemia.

The utility model has the advantages that: 1, simple in structure, easy to make, can guarantee that medicine all enters the central nervous system, directly suppress or the kill tumor cell.2, the medicine that injects the ventricles of the brain can arrive whole CSF lacunas with the mobile regular path of CSF, and the optimum effect of performance medicine obviously is better than intrathecal chemotherapy.In case 3 state of an illness need, percutaneous puncture holds the liquid capsule at any time, and the hardship of the LP or the ventricles of the brain (pond) puncture is avoided repeatedly in inspection of being correlated with and treatment.4, through this device row CSF external drainage, can reduce intracranial pressure rapidly, alleviate the symptom of intracranial hypertension, reduce the plantation of cancerous cell.

It is ommaya capsule structural representation that accompanying drawing 1 is used capsule structural representation, Fig. 2 for the ventricular drainage treatment, and Fig. 3 uses figure for injection, and Fig. 4 is for pushing use figure.Wherein, 1-holds liquid capsule 2-connection tube 3-conduit.

Enforcement of the present utility model is to use silicone rubber injection molded after holding the molding of liquid capsule main part.The conduit routine is made required diameter and is intercepted by Len req, also can be made into hold liquid capsule two ends all with connection tube connect conduit again, connection tube can be with non-toxic material or metal thin tube preparation.

Claims (1)

1. A kind of brain drainage treatment capsule is characterized in that holding liquid capsule [1] two ends by the sphere of silicone rubber preparation is that the end that horizontal shape conduit [3] and being used to inserts the ventricles of the brain has connected the conduit formation through connection tube [2].
