Description

Hydrocephalus shunt pressure adjustable device

The present invention relates to a hydrocephalus shunt pressure device, and in particular to an adjustable hydrocephalus shunt pressure device, which has the convenience and safety of adjustment and control.

According to the human body, under normal and healthy conditions, the ventricles of the brain produce a certain amount of cerebrospinal fluid (CSF) every day, and can automatically absorb and eliminate the cerebrospinal fluid produced by the ventricles to avoid accumulation in the ventricles. However, when a person's brain is damaged due to disease, impact, injury, etc., the human brain cannot completely discharge the water produced, resulting in hydrocephalus; or the circulation pathway of cerebrospinal fluid is blocked, and the cerebrospinal fluid becomes blocked. The absorption and secretion of fluid cannot reach a balance, resulting in excess cerebrospinal fluid not being absorbed by the body and accumulating in the ventricles, which can also cause hydrocephalus.

At present, in order to solve the phenomenon of hydrocephalus, the medical community usually uses ventriculoperitoneal shunt surgery. A hydrocephalus drainage device (one-way water storage valve) is placed between the skull and scalp of the patient with hydrocephalus, and is used in conjunction with the ventricular drainage tube and abdominal cavity. Drainage tubes connect the ventricles and abdominal cavity respectively, shunting the cerebrospinal fluid accumulated in the ventricles to the abdominal cavity for drainage. This medical treatment can achieve better improvement results for patients.

However, when a patient equipped with this hydrocephalus drainage device is lying, sitting or standing, negative pressures with different siphon effects will be generated in the ventricular drainage tube and abdominal drainage tube, especially when the patient moves from a lying position. When changing to a sitting or standing position, the ventricular drainage tube and abdominal drainage tube will If a large siphon effect is produced, since the hydrocephalus drainage device does not have the function of being adjusted at any time, excessive drainage may occur, which is dangerous in terms of control.

The related hydrocephalus drainage device (one-way water storage valve) technology is known in the patent case No. M460631, which provides a structural improvement of the ventricular water storage valve, which includes a seat with a receiving area, and two sides of the seat. There are input pipes and output pipes connected to the accommodation area respectively; an upper cover is movably combined with the base and connected to the accommodation area and the input pipe respectively, and the upper cover is equipped with at least two magnetic bodies; and a cover is provided in the accommodation area. The valve body is connected to the upper cover. With this, the base can be placed between the skull and scalp of a patient with hydrocephalus, and the input tube is connected to the lateral ventricle with the catheter, and the output tube is connected to the abdominal cavity with the catheter to eliminate hydrocephalus, and when used The upper cover can be rotated to adjust the valve body to achieve appropriate flow control in accordance with the pressure in the brain, achieving the effects of being adjustable, not requiring replacement, and having high stability.

The above-mentioned conventional ventricular water storage valve (M460631) technology has the disadvantage that although the upper cover can be rotated to adjust the valve body to control the flow rate, directly rotating the upper cover can easily cause displacement of the seat body and the connected pipes; and it does not have the disadvantage of It can automatically adjust according to the siphon phenomenon at any time to avoid excessive drainage.

In this way, the flow rate is slowed down by the compression of the upper and lower coverings, which prevents the drainage of hydrocephalus due to the patient sitting up or standing up. A large siphon effect is produced in the tube to avoid excessive suction of hydrocephalus.

The aforementioned anti-siphon device (M485699) technology of the conventional hydrocephalus drainage tube, plus the device (24) used to adjust the intracranial pressure from outside the skull, is located on the abdominal drainage tube (22) and the one-way control Between the valve (23), that is, the anti-siphon device (24) is independently provided in combination with the one-way control valve (23), and the two are integrally formed, so that the conventional technology will simultaneously form an imaginary creation.
