Problems solved by technology

Anti-hydrostatic pressure difference is the main problem that needs to be faced in the treatment of hydrocephalus at present. After the human body is implanted with a shunt circuit (such as a ventriculo-peritoneal shunt), due to changes in the body position, supine or upright, etc., The two ends of the shunt pipe will generate an additional hydrostatic pressure difference due to the height difference. For example, there will be a vertical drop between the head end of the shunt pipe and the abdominal cavity when the person is in an upright position, but in the supine position, this drop will follow. Due to the change of body position, an additional pressure difference will be added after the shunt circuit is implanted in the human body, and this constantly changing hydrostatic pressure difference is not good for the treatment of hydrocephalus, as in The upright state will lead to excessive shunt, the patient will have postural headache, and severe cases will have secondary intracranial hemorrhage, and the shunt will be insufficient in the supine state, and the clinical symptoms of the patient will not be effectively relieved.

Embodiment approach 1

[0034] Embodiment 1: It is a preferred implementation process of the device of the present invention.

[0035] The preferred implementation position of described device: as attached Figure 1-3 As shown, the end of the fluid inlet (19) faces the head of the human body, the end of the fluid outlet (20) faces the abdomen of the human body, and the direction of the long axis is parallel to the direction of the long axis of the human body.

[0036]The pressure change process of the supine position and the upright position is as follows: in the supine position, the gravity turntable (2) mass block (6) rotates to the lowest point of the center of gravity due to the action of gravity (both left and right lowest directions are acceptable). At this time, " The included angle between mass block (6)-rotating shaft (10)" and "rotating shaft (10)-spherical seal (23)" is greater than or equal to 90 degrees, and the gravity turntable (2) mass block (6) is opposite to the lower arc-shaped shr...

Embodiment approach 2

[0038] The process of pressure change when the device transitions between the supine position and the upright position: as attached Figure 1-3 As shown, when transitioning between the supine position and the upright position, the included angle between "mass (6) - rotating shaft (10)" and "rotating shaft (10) - ball seal (23)" is between 0-90 degrees Then, the compression effect of the mass block (6) on the arc-shaped shrapnel (8) below varies between "0" and the maximum value. The compression produces different changes, that is, the smaller the angle between "mass (6)-rotating shaft (10)" and "rotating shaft (10)-ball seal (23)", the greater the pressure at the ball seal (23), The larger the angle between "mass block (6)-rotating shaft (10)" and "rotating shaft (10)-ball seal (23)", the smaller the pressure at the ball seal (23), resulting in the difference in adapting to changes in human body positions. Height difference, which is the pressure change of the hydrostatic pre...

Embodiment approach 3

[0040] The fluid flow process of described device: as attached Figure 1-3 As shown, the human body in the upright state additionally increases the hydrostatic pressure difference between the head end and the abdominal cavity end. According to the setting of the device, the pressure at the ball seal (23) in this position is just the extra hydrostatic pressure difference in the upright state. Water pressure, at this time, the fluid enters the fluid chamber (22) in the housing (16) through the fluid inlet (19), and acts on the ball seal (23), the fluid passes through the ball seal (23), and passes through the liquid outflow hole (24), and flow out from the fluid outlet (20). When the human body is in the supine position, the additional hydrostatic pressure difference between the head end and the abdominal cavity end disappears. At this time, the sphere seal (23) is naturally blocked without additional pressure, thereby not increasing the fluid resistance. During transition, the...

Abstract

The invention provides an anti-gravity device which is applied to the human body and resists excessive ventriculoperitoneal shunting or insufficient ventriculoperitoneal shunting caused by posture change. The device is mainly applied to ventriculoperitoneal shunting treatment of hydrocephalus of the cerebral neurosurgical department. The device is characterized by having the function of resistingpositional hydrostatic pressure generated due to the posture change of the human body.

Description

technical field [0001] The invention relates to an anti-gravity device applied to the human body to resist excessive shunting or insufficient shunting after ventriculoperitoneal shunt surgery caused by body position changes. It is mainly used in the ventriculoperitoneal shunt treatment of neurosurgery hydrocephalus, and belongs to the field of surgical medical devices. Background technique [0002] Hydrocephalus is a common disease in neurosurgery, which is a kind of disease caused by poor circulation of cerebrospinal fluid. According to the cause of the disease, it can be divided into congenital hydrocephalus in children and secondary hydrocephalus. Secondary hydrocephalus includes craniocerebral trauma, subarachnoid hemorrhage, encephalitis, neurosurgery and other factors. hydrocephalus. According to the level of intracranial pressure can be divided into high pressure hydrocephalus and normal pressure hydrocephalus. [0003] In the treatment of hydrocephalus, ventricle-p...
