Abstract
The utility model belongs to the field of a medical appliance. The main technique of the utility model is that the utility model adopts an air-sucking sac and a drainage bottle; a connecting rubber tube is arranged between the air-sucking sac and the drainage bottle; the rubber tube is tightly matched with an air-sucking nozzle on the air-sucking sac and an air-sucking tube on the drainage bottle; a drainage tube is also arranged on the drainage bottle, and a drainage rubber tube is tightly pressed on the drainage tube. The air-sucking tube and the drainage tube are tightly matched with the rubber wooden bottle plug of the opening of the drainage bottle; the air-sucking tube and the drainage tube totally open into drainage bottle. The air-sucking tube and the drainage tube are respectively provided with a one-way valve; a one-way exhaust valve is arranged on the air-sucking sac.
Description
This utility model belongs to medical instruments field.Be applicable to gastrointestinal decompression and operation back draining fluids.
At present, gastrointestinal decompression and operation back adopt the way of drain more, in the good hospital of medical condition, are the central negative pressure drainages that adopts, and use in several specific wards exactly, use the place just to be restricted, and motility is little.
Adopt the air bag that spring is arranged to produce negative pressure drainage in general hospital, this drain is controlled with regard to difficulty or ease, and air is backflowed, and causes malleation, if deal with improperly, can bring adverse consequences to patient.For the reliability that changes negative pressure and the motility of use, be necessary to design a kind of new depression drainage device.
The purpose of this utility model designs a kind of low price exactly, and is flexible, the disposable drainage device of negative pressure good reliability.
This utility model major technique adopts a suction air, a drainage bottle, between suction air and the drainage bottle sebific duct of connection is arranged, suction nozzle presses and cooperates on vacuum noz(zle) on sebific duct and the air bag and the drainage bottle, also has a drainage tube on the drainage bottle, and drainage tube tightens and presses a drainage hose, suction nozzle and drainage tube cooperate with drainage bottle chewing gum bowling pin jam-pack, and these two pipes all lead in the bottle, and a check valve is respectively arranged on suction nozzle and the drainage tube, and an one-way exhaust valve is arranged on the suction air.
Major advantage of the present utility model is: a check valve is respectively arranged on suction nozzle and the drainage tube, guarantee negative pressure in patient's cavity, this cover drainage device is small and exquisite, use conveniently, and the manufactured materials low price, cost is low, is convenient to make disposable drainage device.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is an a whole set of sketch map of the present utility model.
Describe details of the present utility model and working condition in detail below in conjunction with Fig. 1.
Vacuum noz(zle) (2) and exhaust check valve (3) are arranged on the suction air (1).Bakelite bottle stopper (9) is arranged on the drainage bottle (10), two pipes of this bottle stopper of glue tight fit, one is suction nozzle (11), one is drainage tube (6), on these two pipes a check valve is arranged respectively, check valve is to have garden pearl (8) and spring (7) to form, and suction nozzle and drainage tube all lead in the drainage bottle.Check valve on suction nozzle and the drainage tube is to be negative pressure in the drainage bottle for guaranteeing, guarantees in patient's cavity set for negative pressure simultaneously.Manufacturing of check valve is that two pipe glass tubings are arranged, make a platform valency of putting spring (7) on the mouth of a glass tubing, wear into slick garden arc on the mouth of another root glass tubing, match with the garden arc of garden pearl (8), spring and garden pearl put into two glass tubings mouthful on dock and seal.Have sebific duct (4) to be connected between vacuum noz(zle) (2) and the suction nozzle (11), all adopt the junction presses cooperation.There is the sebific duct (5) that presses cooperation to lead in patient's the cavity on the drainage tube (6).Suction nozzle (11) with draw chimney filter (6) and also can be plastic tube.Sebific duct (4) also can be a plastic tube with sebific duct (5).An one-way exhaust valve (3) is installed in the rear end of suction air (1), and the material of suction air can be a capsule, also can be plastic bag, but good elasticity must be arranged, and elasticity satisfies the requirement that produces negative pressure.
