Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a lateral ventricle drainage device. Background Art
[0002] Patients with intraventricular hemorrhage will have a ventricular drainage device placed in the ventricle to drain the bloody cerebrospinal fluid out of the lateral ventricle, thereby reducing intracranial pressure and the stimulation of bloody cerebrospinal fluid on the brain. The height difference between the cerebrospinal fluid outlet of the ventricular drainage tube and the plane of the frontal angle of the lateral ventricle should be maintained at 10 to 15 cm to ensure the safe outflow of cerebrospinal fluid. If the drainage bottle is too high, the cerebrospinal fluid cannot be drained, resulting in increased intracranial pressure. If the drainage bottle is too low, the cerebrospinal fluid will be over-drained too quickly, resulting in a too rapid drop in intracranial pressure; hanging the drainage bottle too high or too low will lead to adverse consequences. At present, the lateral ventricle drainage bottle is generally hung on the infusion stand beside the bed, and the height of the drainage bottle is generally measured by visual inspection + scale. This method has the following shortcomings: 1: Visually inspecting the zero point position, there is a subjective feeling, and there is a certain error in measuring the hanging height of the drainage bottle with a scale + visual inspection of the zero point position. 2: After the drainage bottle hanging height is confirmed, if the bed head height changes, the patient's lateral ventricle frontal angle plane also changes. However, since the drainage bottle hanging height does not change, the drainage bottle hanging height and the lateral ventricle frontal angle plane also change. This causes excessive drainage of cerebrospinal fluid or poor drainage. 3: During the drainage process of lateral ventricle drainage, there is a certain probability that the drainage tube will be blocked. 4: When there is a sudden and drastic change in intracranial pressure (such as suddenly raising the head or coughing violently), cerebrospinal fluid may be over-drained and it is very likely that gas will reflux into the skull, causing pneumocephalus. Utility Model Content

When in use, the sleeve 4 is fixed to the uppermost end of the hanging frame 3 through the No. 1 nut 401. The distance between the No. 1 nut 401 and the laser pen at the bottom end of the sleeve 4 is 5 cm. When in use, the laser pen is used to locate that the lower end of the sleeve 4 is in the same plane as the frontal angle of the patient's lateral ventricle. When the drainage bottle fixture 5 is located at the uppermost end of the sleeve 4, the outlet end of the drainage bottle 5 is flush with the top end of the sleeve, the distance between the laser pen (i.e., the frontal angle of the patient's lateral ventricle) and the outlet end of the drainage bottle 5 is 15 cm, the drainage bottle fixture 5 slides to the bottom to the position of the No. 1 nut 401, and the height of the drainage bottle fixture 5 is 5 cm, so the sliding range of the drainage bottle fixture 5 on the sleeve 4 is 5 cm.

Repeated squeezing of the drainage tube 7 can avoid blockage of the drainage tube caused by slow solidification of the fluid flowing in the drainage tube.
[0008] The drainage monitoring structure 9 includes a light generator No. 901 and a light receiver No. 902, and the light generator No. 901 and the light receiver No. 902 are arranged on both sides of the head end of the drainage bottle 6. The drainage volume monitoring structure adopts a PLC controller. When no cerebrospinal fluid drips out from the outlet of the lateral ventricle drainage bottle. The light generated by the light generator will not be refracted due to the lack of liquid interference. The light of the light generator passes through the lateral ventricle drainage bottle and is received by the sensing plate of the light receiver. The controller receives the signal of the light receiver and does not process it. When cerebrospinal fluid drips out from the outlet of the lateral ventricle drainage bottle. The light generated by the light generator will be refracted due to the interference of liquid. The light of the light generator is not received by the sensing plate of the light receiver. The controller does not receive the signal of the light receiver and counts once. The discharge rate of cerebrospinal fluid can be evaluated more accurately.
[0009] All the above data can be transmitted to the mobile terminal through the WIFI module. The APP can accurately control the patient's cerebrospinal fluid discharge rate and effectively avoid air reflux into the skull.
[0010] The flow blocking structure 2 and the drainage monitoring structure 9 control the rotation of the elliptical knob 102 through a PLC controller to block the fluid in the drainage tube 7 and monitor the drainage speed. The drainage tube 7 is arranged on the side of the elliptical knob 102, and the drainage tube 7 is arranged in a groove. The other side of the groove is provided with the raised platform 101. When the elliptical knob 102 is rotated until the major axis and the raised platform 101 are in a straight line, it contacts the drainage tube 7 in a clamped state. When the minor axis and the raised platform 101 are in a straight line, the drainage tube 7 is in a fully open state.
