The specific embodiment
As can be seen from Figure 1, a kind of simple and easy cranium brain external drainage device comprises puncture drainage assembly, conduit 8, liquid-collection bag 14 etc.
This utility model puncture drainage assembly comprises drainage catheter 3, rustless steel guide pin 4, Rule adapter 6 etc.Be that product must assembly, the fore-end tube wall of drainage catheter 3 is provided with conduction hole 1, and tube wall is provided with drainage catheter scale 2, and when needs carried out the intracranial surgical drainage, it placed intracranial under the guiding of rustless steel guide pin 4, carried out puncture drainage.Rule adapter 6 is a standard component, can connect the tail medicated cap on it, also can dispose the tail medicated cap in addition.Be fixed on patient's drain position by ring for fixing.
The said liquid-collection bag of this utility model 14 is communicated with drainage catheter 3 by conduit 8, and wherein Rule adapter 6 is connected with cone joint 7 on the conduit 8, and liquid-collection bag 14 inlets pass through cone joint 10 and are connected with conduit 8.Liquid-collection bag 14 bottoms are provided with leakage fluid dram cone joint 17 and liquid stopping clamp 16.The said liquid-collection bag 14 of this utility model is provided with link 11, can hang on the height-adjustable support.Liquid-collection bag 14 tops are provided with anti-backflow device 12 and air filter 13, and air filter 13 is heat seal air filtration films on bag.Liquid-collection bag 14 is provided with metering scale scale 15, is used for collecting, metering drain liquid.Liquid-collection bag 14 is adjusted its suspension height by link 11, and then patient's intracranial pressure is regulated.Regulate drainage speed by link 11 height, thereby the control drainage speed is regulated the cranium pressure, carries out cranium hydrocrania external drainage safely, in time.
Be connected with three-way valve 9 on the said conduit 8 of this utility model.
The said puncture drainage assembly of this utility model also is provided with sleeve pipe draw point 5, so that carry out subcutaneous traction.The puncture drainage assembly is the necessary assembly of external drainage system.When needs carry out the intracranial surgical drainage, on patient's head skull, open a hole that is of moderate size, earlier rustless steel guide pin 4 is inserted in the drainage catheter 3, as shown in Figure 2.Under CT guides, drainage catheter 3 inserted and treat to do subcutaneous traction as needs in the drain position, then extracting terminal joint sleeve draw point 5 afterbodys of rustless steel guide pin 4 backs, as shown in Figure 3, draw routinely and get final product at drainage catheter 3.As not needing to do subcutaneous traction, extracting rustless steel guide pin 4 backs directly in the drainage catheter 3 terminal combinations that connect Rule adapter 6, as shown in Figure 4.And then can connect liquid-collection bag 14 enforcement drains.This combination is simple, convenient, relies on liquid-collection bag 14 to place height and controls drainage speed, regulates cranium and presses, and avoids inadequate drainage or drain excessive.
This utility model is simple in structure, and processing and manufacturing is easy, and is easy for operation, the backflow of drain liquid can not occur and cause patient's cross infection, can reflect the amount of liquid of drain at any time accurately.Be particularly suitable for making nontoxic aseptic disposable cranium brain external drainage utensil, safe and convenient to use.
