Abstract
A medical water-resisting ventilated external drainage bag adopts the following main technical scheme that through holes are formed at the upper parts on the side surfaces of a liquid collecting bag; water-resisting ventilated membrane covering the through holes is arranged on each through-hole, and the membrane is in sealing connection with the liquid collecting bag near the through holes; a non-return sleeve adopting a cylindrical diaphragm is arranged at the end part of a liquid feeding pipe in the cavity of the liquid collecting bag, wherein one end of the liquid feeding pipe is fixed outside the liquid feeding pipe and sealed while the other end thereof is free; and a sterile two-way valve is arranged at the end part of the liquid discharge pipe outside the cavity of the liquid collecting bag, wherein one passage of the valve is a sterile liquid outlet and the other passage is a sterile pin plug. The external drainage bag can continuously collect drainage liquid, thereby having low probability of forming intracerebral pneumatosis, avoiding reversed current of liquid in the bag or drainage liquid, and ensuring normal and stabile pressure in the bag; and the external drainage bag can be used safely, can effectively prevent cross infection, and guarantees curative effect, and have simple and convenient operation, easy processing and portability,.
Description
Technical field this utility model relates to a kind of Medical Instruments, especially for the device of fraction constant drainage collection in the various bodies.
Background technology discloses a kind of " external ventricle drainage device " (patent No. 200620088941 on the utility model patent communique on October 10th, 2007,6) it is to the effect that: it has a front portion to be provided with the drainage tube of through hole, one end of connection tube links to each other with the drainage tube rear end, the other end links to each other with the weeping pipe of liquid dripping kettle, this minim pipette top be bend pipe its be positioned at liquid dripping kettle, this liquid dripping kettle top be provided with suspender belt and in the opening of air filter mechanism is arranged, lower ending opening links to each other with the liquid-collection bag liquid-inlet by connection tube, this liquid-collection bag lower end is provided with leakage fluid dram, which is provided with aseptic tapping valve, liquid-collection bag top be provided with it fixed mechanism and in the air vent of air filter mechanism is arranged, be provided with the three-way valve that is provided with the pin plug on another valve port on the connection tube of drainage tube and minim pipette.Its weak point is: 1, the air vent on liquid-collection bag top is the pipe that two ends are connected with liquid-collection bag intracavity and atmosphere respectively, adding man-hour will be with itself and liquid-collection bag film hot-pressing together, because both thickness and hardness differ too big, be difficult for processing, and the product that processes easily reveals herein, and is inconvenient to carry; 2, the feed tube outlet directly is connected with the liquid-collection bag chamber, and liquid countercurrent in the liquid-collection bag might take place in not anti-adverse current mechanism, and its consequence is very dangerous; 3, the liquid-collection bag leakage fluid dram is only established aseptic tapping valve, and its function is more single.
The summary of the invention the purpose of this utility model is to provide a kind of energy the lasting medical ventilative external drainage bag that blocks water of collecting drain liquid, drain liquid adverse current and retrograde infection can taking place.This utility model is that the liquid-collection bag with prior art serves as that partly improve its aerofluxus, discharge opeing and feed liquor on the basis.This utility model is the same with existing liquid-collection bag, and main body is the satchel for sealing still.Top, side (one or both sides) at this satchel is provided with through hole, and its size, quantity can design as required, are equipped with the ventilated membrane that blocks water with its covering on each through hole, and near the liquid-collection bag this film and the above-mentioned through hole is tightly connected.The above-mentioned ventilated membrane permeable watertight that blocks water, it can be discharged the gas in the bag, and the liquid in the bag is seen through, and can prevent effectively that like this drain process bag internal pressure from increasing.Above-mentioned liquid-collection bag upper end is provided with feed tube, and the one end is positioned at outside the liquid-collection bag and can links to each other with various conduits, and the other end is positioned at the liquid-collection bag intracavity.Preferably this feed tube end that is positioned at the liquid-collection bag intracavity is provided with non-return cover, and it is the tubular thin film, and its end is fixed on the outer and sealing of feed tube, and the other end is a free end.This is non-return when being enclosed within drying is open, has liquid to exist when using therebetween, and this non-return cover just can be attached to together, thus the time non-return cover be positioned at below the feed tube, liquid can be smoothly by non-return cover under action of gravity.If the liquid-collection bag horizontal is because of agravic effect, liquid that can not passes through from non-return bag; If liquid-collection bag is inverted, non-return bag can take place to curl, sealing automatically.Above-mentioned liquid-collection bag lower end is provided with discharging tube, and it also is that an end is positioned at the liquid-collection bag intracavity, and the other end is positioned at outside the liquid-collection bag chamber.This discharging tube end that is positioned at outside the liquid-collection bag chamber is provided with aseptic two-way valve, a passage of this valve is aseptic leakage fluid dram, and another passage then is provided with the sterile needle plug, the directly discharge opeing of this two-way valve, also pin pump drainage liquid can be passed through, lifting rate and drain age velocity can be controlled better like this.The limit, two lower ends that best above-mentioned liquid-collection bag inner chamber links to each other with leakage fluid dram is an oblique line, their angle less than 180 ° so that effluent concentrate.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.The liquid-collection bag side is provided with volume markings.
This utility model links to each other the liquid-collection bag feed tube earlier in use with drainage tube, be fixed in the height that meets the certain pressure requirement afterwards.When the drain hypervolia of accumulating in the drainage bag, can discharge by aseptic two-way valve.
This utility model compared with prior art has following advantage:
1, sustainable collection drain liquid is difficult for forming pneumatosis in the bag, can not cause bag interior liquid thing or drain liquid adverse current, keeps the bag internal pressure normally stable.
2, safe in utilization, can prevent from effectively cross infection to have guaranteed therapeutic effect.
3, simple, convenient.
4, easily processing, portable.
