Adjustable external ventricular drainage device fixing frame

Abstract

The invention relates to an adjustable external ventricular drainage device fixing frame. The fixing frame comprises a fixed box, a height adjusting rod and an angle adjusting rod, wherein a groove isformed in one side of the fixed box; the locking screw penetrates through the fixed box and extends into the groove; the locking screw is in threaded fit with the fixed box; a gear cavity is furtherformed in the fixed box; gear is arranged in the gear cavity, the gear is connected with a height adjusting knob arranged outside the fixed box through a rotating shaft; a rack is arranged on one sideof the height adjusting rod; the height adjusting rod penetrates through the fixing box and a rack on the height adjusting rod to be matched with the gear, a rotating shaft is arranged at one end ofthe height adjusting rod and penetrates through the head of the height adjusting rod, an angle adjusting knob is arranged at one end of the rotating shaft, the other end of the rotating shaft is connected with the end of the angle adjusting rod, and a hook is arranged on the angle adjusting rod. The fixing device is used for fixing and supporting the external ventricular drainage tube and the drainage device, the height and angle can be adjusted at will, it can be guaranteed that the relative position of the drainage device and the head is fixed, and operation is convenient.

Description

Technical field: [0001] The invention relates to the technical field of medical equipment, in particular to an adjustable ventricular drainage device fixing frame. Background technique: [0002] In clinical craniocerebral surgery, in order to reduce intracranial pressure, the lateral ventricle is often punctured and the cerebrospinal fluid is drained to make the intracranial operation area clearer. Postoperatively, to relieve reactive intracranial hypertension, the lateral ventricle is also commonly used. drainage. When performing outdoor drainage, in order to ensure the safety of drainage and maintain normal intracranial pressure, the suspension height of the ventricular drainage device is relatively strict. It is usually required to be fixed at a position 10-15 cm above the level of the patient’s external auditory canal. In current clinical applications, the outdoor The drainage device is generally fixed on the side of the bed board or the infusion stand. Because the patient s...

Problems solved by technology

[0004] The present invention aims to provide an adjustable external ventricular drainage device fixing frame, which can be adjusted according to the patient's lying posture at any time during the external ventricular drainage device, and the vertical distance between the external ventricular drainage device and the plane of the patient's external auditory canal is kept relatively fixed , to ensure the normal intracranial pressure of the patient, and at the same time facilitate the operation and use of the medical staff, and solve the problem that the existing external ventricular drainage device fixing method cannot keep the vertical distance between the external ventricular drainage device and the plane of the patient's external auditory canal relatively fixed, and cannot be adjusted accurately
