The normal encephalic pressure can be guaranteed, and the crossover infection can be effectively prevented. The utility model is convenient and safe, which secures the therapeutic effect. Moreover, the utility model is operated easily and conveniently, and can not only do flow drainage but also freely inject medicine in a drainage flow cavity.
Description
Technical field this utility model relates to a kind of Medical Instruments, especially for fraction constant drainage 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, tube wall only has several apertures, easily stopped up and cause inadequate drainage by block drain, and can't be issued to the purpose of constant drainage in the situation of the certain intracranial pressure of maintenance, usually because drains such as excessive drainage of cerebrospinal fluid cause intracranial low pressure, anti-stream also taking place easily cause that drive in the wrong direction cross infection or intracranial are hemorrhage again, jeopardizes patient's life.
The summary of the invention the purpose of this utility model is to provide a kind of can keep that intracranial pressure is normally stable, constant drainage is unobstructed, be difficult for taking place the external ventricle drainage device of retrograde infection.This utility model mainly includes: drainage tube, three-way valve, liquid dripping kettle, liquid-collection bag and connection tube.Wherein, drainage tube can be the common medical grade silicon rubber pipe that the front portion is provided with through hole, but preferably internal diameter is 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 2～3 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 the minim pipette of liquid dripping kettle by connection tube.This liquid dripping kettle has a hollow housing, and its top is provided with the opening that communicates with atmosphere, is provided with air filtration mechanism in it, and it can make liquid dripping kettle be connected with atmosphere, can guarantee to enter the sterile air in the liquid dripping kettle again.Also be provided with the suspender belt that is used to hang liquid dripping kettle on liquid dripping kettle top.Be provided with minim pipette in liquid dripping kettle, this vertical minim pipette top is bend pipe, the drain adverse current can not take place to keep drain liquid to continue to splash in the kettle, the minim pipette bottom pass the liquid dripping kettle wall and fixing with its on.Reach the minim pipette of liquid dripping kettle outside, link to each other with drainage tube by connection tube.The opening of liquid dripping kettle lower end is a liquid outlet, and it links to each other with liquid-collection bag by connection tube.Preferably the liquid dripping kettle outer surface is provided with volume markings.This liquid-collection bag is a satchel, and the upper end is provided with the liquid-inlet that links to each other with connection tube, and the lower end is provided with leakage fluid dram, and this leakage fluid dram is provided with aseptic tapping valve.Also be provided with air vent on this liquid-collection bag top, be provided with air filtration mechanism in it.The air vent that should be connected with atmosphere can prevent that drain process bag internal pressure from increasing.The limit, two lower ends that best liquid-collection bag inner chamber links to each other with leakage fluid dram is an oblique line, and their angle is less than 180 °, so that effluent is concentrated.Be provided with its fixed mechanism in addition on liquid-collection bag, it can be the suspender belt that links to each other with liquid-collection bag, also can be to establish through hole on liquid-collection bag.Be provided with three-way valve to the diseased region administration for convenient on the connection tube of drainage tube and minim pipette, two valve port links to each other with connection tube 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 this connection tube and be provided with the control valve corresponding with it, it can press from both sides and close connection tube, in order to the speed of control drain and administration.Preferably the liquid-collection bag outer surface is provided with volume markings, and it can represent to draw fluidic amount.
This utility model is except that drainage tube, and remainder all assembles in advance, therefore in use, will draw pin earlier and insert in the drainage tube, enters the intracranial appointed part through sphenotresia, withdraws from and draws pin, and is again that an end of connection tube is coupled.Then liquid dripping kettle is suspended on the somewhere, it highly meets the requirement of intracranial cerebrospinal pressure.Afterwards liquid-collection bag is fixed on the position that is lower than liquid dripping kettle.Promptly open the path that three-way valve leads to liquid-collection bag as the need drain, make the blood of drawing, cerebrospinal fluid etc. continue to flow in the liquid-collection bag.When the drain hypervolia of accumulating in the liquid-collection bag, can discharge drain liquid by aseptic tapping valve.When needs when intracranial injects medicine, close the path that three-way valve leads to liquid-collection 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. sustainable adequate drainage, be difficult for forming pneumatosis in the brain, and can not cause cerebrospinal fluid or drain liquid adverse current, guarantee that intracranial pressure is normally stable.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.
