Abstract
A cerebral surgery fluid drainage device. The fluid drainage tube of this utility model is made of medical silicon rubber tube with internal diameter of over 1.8mm; 2-8 trough holes with diameter of over 2mm are made at the front section of the tube; the length of the coordinating lead needle exceeds that of the fluid drainage tube; the outside diameter of the lead needle is basically identical with the internal diameter of the fluid drainage tube. One end of the fluid drainage conduit is connected to the rear end of the fluid drainage tube; the other end of the fluid drainage conduit is connected to the fluid inlet of the fluid drainage bag; fluid discharge outlet is set at the lower part of the close-type fluid drainage bag; sterile puncture fluid discharge valve is set at the top of the fluid drainage bag; fixing mechanism is set in the fluid drainage bag. This new utility model ensures smooth fluid drainage, which prevents the intracephalic pneumatosis and reverse flow of blood; effectively prevents the cross infection, which ensures much convenience, safety and outstanding treatment effect; features simple operation: it can not only realize fluid drainage, but also assure the injection of medicine into the fluid drainage cavity from time to time and be placed effectively at any parted needed.
Description
Technical field this utility model relates to a kind of Medical Instruments, especially for fraction drain such as intracranial hematoma, abscess, cerebrospinal fluid and inject the device of medicine to intracranial.
Background technology is present, Wicresoft bores cranium intracerebral hematoma suction and has been widely used in clinical, people design many external drainage devices for this reason, as disclosed a kind of " drainage tube device " (patent No. 03244757.4) on April 7th, 2004 utility model patent communique its to the effect that: drainage tube is made of trocar sheath, interior pipe and seal wire, the trocar sheath head is slick and sly closed, but be provided with some apertures around the tube wall of distance head top 0.5～2 centimeters, its afterbody is that horn mouth is connected with drainage bag; Interior Guan Yiduan inserts in the trocar sheath from the tube wall of trocar sheath afterbody, and up to head, and the other end stretches out the overcoat tube wall, and is gapped between interior pipe and the trocar sheath; The rustless steel seal wire interts in interior pipe.Its weak point is that tube wall only has several apertures, is easily stopped up by block drain, causes inadequate drainage; The drainage bag supporting with it is many to be replaced by urethral catheterization tubular type Drainage urine bag, not only is difficult for drain, but also causes retrograde cross infection easily, jeopardizes patient's life.
The summary of the invention the purpose of this utility model is to provide the cranium brain external drainage device that a kind of drain is unobstructed, be difficult for taking place retrograde infection.This utility model mainly includes: drainage tube, three-way valve, drainage bag and drainage catheter.Wherein, drainage tube is an internal diameter greater than 1.8 millimeters medical grade silicon rubber pipe, and its front end is round blunt.The front end of this round blunt can be the sealing be the closed drainage pipe, also can be provided with opening immediate boiling drainage tube, no matter open type still is the closed drainage pipe, the front portion of its pipe is equipped with the through hole of 2～8 apertures greater than 2mm.Send into the intracranial lesion position smoothly for the part of this drainage tube front portion being established through hole, this drainage tube also is furnished with the draw pin corresponding with it.This draws pin length greater than drainage tube, and external diameter equals the drainage tube internal diameter substantially, and it inserts in the drainage tube not only increases its rigidity, has been full of the space of drainage tube simultaneously again, and its forward opening is sealed, and prevents that cerebral tissue from entering in the drainage tube; If the open type drainage tube can be sealed the opening of its front end again, make it to become the round blunt similar to the closed drainage pipe, reduce neural tissue injury.Preferably drainage tube is provided with scale, so that understand the degree of depth that drainage tube enters intracranial.After drainage tube arrives the intracranial appointed part, withdraw from and draw pin, link to each other with other drainage component by drainage catheter.One end of this drainage catheter links to each other with the drainage tube rear end, and the other end links to each other with drainage bag, and this drainage bag is the closed drainage bag, it is airtight satchel, the upper end is provided with the liquid-inlet that links to each other with drainage catheter, and the lower end is provided with leakage fluid dram, and this discharge opeing liquid mouth is provided with aseptic puncture tapping valve.The limit, two lower ends that best drainage bag inner chamber links to each other with leakage fluid dram is an oblique line, and their angle is less than 180 °, so that drain liquid is concentrated.Be provided with its fixed mechanism in addition on drainage bag, it can be the suspender belt that links to each other with drainage bag, also can be to establish through hole on drainage bag.Be provided with three-way valve for convenient to the diseased region administration on drainage catheter, two valve port links to each other with drainage catheter respectively, and another valve port is provided with the pin plug, opens the pin plug and just can easily medicine be injected the drain chamber.Be preferably in drainage catheter and be provided with the control valve corresponding with it, it can press from both sides and close drainage catheter, in order to the speed of control drain and administration.
This utility model in use, to draw pin earlier inserts in the drainage tube, enter the intracranial appointed part through sphenotresia, withdraw from and draw pin, one end of drainage catheter is linked to each other with the drainage tube exposed junction, then drainage bag is fixed on the other position that is lower than head of bed,, makes that bag is intrinsic pressure to be lower than intracranial pressure so that keep drainage bag to be negative pressure.Promptly open the path that three-way valve leads to drainage bag as the need drain, the blood of drawing, cerebrospinal fluid etc. are flow in the drainage bag.When the drain hypervolia of accumulating in the drainage bag, the syringe pump after the available sterilization is discharged drain liquid.When needs when intracranial injects medicine, close the path that three-way valve leads to drainage bag, meanwhile the administration path is opened, and opens the pin plug that is located on the three-way valve valve port and connects syringe medicine is injected intracranial.
This utility model has following advantage compared to existing technology: 1 drain is unobstructed, is difficult for forming pneumatosis in the brain, can not cause blood back flow.2. prevented cross infection effectively, not only convenient but also safety has guaranteed therapeutic effect.3. simple to operation, not only can drain, also can inject medicine to the drain chamber at any time, also can be placed on the position of any needs.
