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 (14) faces the head of the human body, the end of the fluid outlet (15) 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: under the supine position, the gravity pendulum (10) is subjected to the action of gravity, and the center of gravity of the pendulum rotates and moves to the lowest point (both left and right lowest directions are acceptable). At this time, " Gravity pendulum (10) center of gravity - gravity pendulum center point (12)" and "gravity pendulum center point (12) - sphere seal (20)" angle is 90 degrees, at this moment, gravity pendulum center part The...

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, "gravity pendulum (10) center of gravity point-gravity pendulum center point (12)" and "gravity pendulum center point (12)-spheroid seal (20) )” fluctuates between 0-90 degrees, and then under the action of the cam structure (11) at the center of the gravity pendulum, the moving distance of the pendulum push rod (9) in the casing (2) is within “0 " and the maximum value, so that the elastic force of the pressure spring (7) varies between "0" and the maximum value, that is, "gravity pendulum (10) center of gravity - gravity pendulum center point (12)" and "gravity Pendulum center point (12) - sphere seal (20)" the smaller the angle, the greater the pressure at the sphere seal (20), "gravity pendulum (10) center of gravity - gravity pendulum center point (...

Embodiment approach 3

[0040] The fluid flow process of described device: as attached Figure 1-3 As shown, the hydrostatic pressure difference between the head end and the abdominal cavity is additionally increased when the human body is in an upright state. According to the setting of the device, the pressure at the ball seal (20) in this position is exactly the additional hydrostatic pressure in the upright state. At this time, the liquid enters through the fluid inlet (14) and acts on the ball seal (20), the fluid passes through the ball seal (20), and the liquid through the sleeve flows out of the side hole (3) into the fluid chamber (19) , flowing out from the fluid outlet (15). 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 ball seal (20) is naturally blocked without additional pressure, thereby not increasing the fluid resistance. During the transition between posit...

Abstract

The invention provides an anti-gravity device which is applied to the human body and resists excessive shunting or insufficient shunting caused by posture change after ventriculo-peritonal shunt operations. 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 resisting positional 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...
