Abstract
The utility model relates to a disposable negative pressure drainage device. The utility model is composed of a telescopic air sac with an organ type, a drainage opening, an air plug and a drainage regulator; the telescopic air sac is made of high-pressure polyethylene film, a compression spring is arranged in the air sac, a sealing cushion and an opening cover are matched with the opening of the air sac, an air-discharging opening (liquid-discharging opening) is arranged on the opening cover, and the air plug is matched with the drainage opening. The utility model has the advantages of simple structure, convenient operation, low cost, cleanness and sanitation; the negative pressure can be formed without any energy source, and the utility model can be operated by medical care personnel and patients.
Description
This utility model belongs to a kind of medical apparatus and instruments, and specifically it is to be used for performing the operation or perform the operation a kind of special implement that blood that the back oozes out affected part stream or body fluid drainage procedure use.
Abdomen is outer, breast outer or the brain outer operation in, depression drainage device is a kind of equipment commonly used.In general hospital operating room, all have the negative pressure device supporting with vacuum pump.Also normal the use ridden the piston type depression drainage device in the simple and easy operation process.But this kind equipment volume is bigger, complicated operation, and price is also very expensive.When being used for the postoperative drainage nursing often is to make provisional negative pressure bottle by medical personnel.Promptly earlier take air in the large-scale wide mouthed bottle away a part, form negative pressure in the bottle with vacuum extractor.Compress the rubber stopper that has drain interface and air vent then.Be connected on again on the pre-drainage tube of keeping somewhere of patient's postoperative.But do the postoperative drainage nursing of long period, use and be still very trouble.Particularly the blood that comes out of drain, that pus body fluid cleans is very inconvenient, causes the difficulty of nursery work.Careless manipulation also can produce cross infection.Thereby medical personnel wish to design a kind of simple, cheap disposable negative pressure drainage device.Be beneficial to flow medical treatment and postoperative care, and can prevent cross infection and reduce medical personnel's labor intensity.
The purpose of this utility model is to adopt medical plastic to make the depression drainage device of disposable application, makes its effect that not only can produce medical negative pressure drainage vessel, and easy and simple to handle, cheap, be easy to apply.To thoroughly avoiding cross infection to play a key effect.
Basic design of the present utility model is to utilize medical plastic (for example high pressure polyethylene) directly to be blow molded into a container that can form negative pressure.This negative-pressure container is designed to a cylindrical telescopic organ type air bag, and presets the compression spring in air bag.Such structure can make air bag outside under the force compresses volume diminish spring energy-storage simultaneously.Along with making bag volume, freely extending of spring strengthen negative pressure in the shape air bag.For guaranteeing the formation of negative pressure, whole air bag top is shrunk to the bottleneck shape.Add bottle cap on the bottleneck, be air hermetic between the two and be connected.Draining hole and aerofluxus (liquid) mouth is set on bottle cap.Whole bag volume diminishes when applying outer force compresses spring like this, and gas is discharged from air vent.If after this close air vent, remove then spring elongation promotion airbag inflation of external force, volume strengthens, and makes and forms negative pressure in the air bag.If connect sebific duct and be communicated to drain position from draining hole this moment, will be among draining hole is inhaled into air bag by draining fluids.If a drain also can repeat above operation, repeatedly drain inadequately once more.Add at draining hole and to add external force an actuator (or switch) then also can suck a great deal of liquid in air bag after liquid is discharged from aerofluxus (liquid) mouthful.And then repetitive operation, till finishing drain.Needn't clean recovery with the back utensil, so not only easy, and can significantly reduce medical personnel's labor intensity, the more absolute cross infection chance of having avoided.
How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes.
Fig. 1 is structural representation of the present utility model (figure is partly cutd open in the part).
But Fig. 2 is the structural representation (figure is partly cutd open in the part) of reducing interface.
Wherein 1 represent scalable organ type air bag, 2 representative compression springs, 3 represent bottleneck, and 4 represent bottle cap, and 5 represent gasket seal, 6 represent aerofluxus (liquid) mouth, 7 represent draining hole, and the gas of 8 representative plugs on aerofluxus (liquid) mouth is stifled, and 9 represent flexible pipe, 10 represent drain actuator (control valve), and 11 represent drainage hose.
The free extended length of compression spring 2 has guaranteed that organ type air bag 1 forms maximum volume.Pad 5 between bottle cap 4 and the bottleneck 3 guarantees that air bag does not leak.It is to be connected for the sebific duct that adapts to different-diameter with the endoporus reverse frustoconic that aerofluxus (liquid) mouth 6 that is provided with on bottle cap 4 is designed to the round platform profile especially with draining hole 7.Can socket to big directly sebific duct, connect than can filling in of minor diameter.It is very convenient when this makes clinical practice.Block up 8 with aerofluxus (liquid) mouthful 6 gas that have that match.Aerofluxus when applying external force (liquid) mouthful unnecessary gas of discharge.Apply after the external force gas stifled 8 beyond the Great Wall.After cancelling external force, negative pressure in spring restoring force effect lower gasbag 1 can expand the formation capsule automatically.If draining hole 7 joined with drainage hose and just can implement drainage procedure this moment.Obviously, for the easy to operate drain actuator 10 (or being called control valve) that between draining hole 7 and drainage hose 1, also should add in the use.The one head is connected on the draining hole 7 when operation, and one connects drainage hose 11.Operate so just to be easy to grasp and be unlikely in a rush.
According to the depression drainage device that above structure is made, all the other all are working of plasticss outward to remove the compression spring, handling ease, low price.Do not use any energy in the work, get final product by the medical personnel one man operation.Can oneself operate through simple practice patient, very convenient, be the portable apparatus that is worthy of popularization.
