Detailed Description

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.

Referring to fig. 1-7, the present application discloses a drainage device, which includes a drainage portion and a pressure regulating structure; the drainage part is connected with the pressure regulating structure through a U-shaped pipe 13; the drainage part comprises a Y pipe 5, a straight pipe 12, a drainage bag 1 and an empty groove 7, wherein the Y pipe 5 is connected with the drainage bag 1 through the straight pipe 12, the straight pipe 12 is connected with the drainage bag 1 through a quick connector 4, and a sodium citrate anticoagulation coating is adopted in the Y pipe and stretches into the chest wall of a patient to drain. The anticoagulation design avoids blockage of the pipeline. It is to be noted that, in the prior art, an anticoagulant coating is coated inside the Y tube, and the substrate is directly immersed in the reaction solution of each step to perform a corresponding reaction. The method for preparing the anticoagulation coating is simple to operate, high in controllability, free of complex equipment and operation, and good in durability.

As shown in fig. 6, the suction port 501 in the Y-tube 5 is directly inserted into the chest cavity of a patient to drain effusion, the drug injection pipeline 503 is communicated with the injection port 502, and directly penetrates into the chest cavity, and when the drug is injected, the drug is injected into the drug injection pipeline 503 through the injection port 502 and then directly reaches the chest cavity through the drug injection pipeline 503. The whole pipeline is internally coated with an anticoagulation coating layer to avoid the problem of blockage of the pipeline caused by clinical common blood coagulation, and the detection pipe orifice 504 is arranged outside a patient when the suction interface 501 is used for sucking, and when the detection pipe orifice 504 is not needed to be used, the detection pipe orifice 504 is covered with a cover matched with the pipe diameter so as to be in a closed state; when some effusion is required to be extracted for detection, the cover of the detection pipe orifice 504 is taken away, and then some effusion is extracted from the detection pipe orifice 504 for detection.

The quick connector 4 has the following features: the drainage tube can be taken out or connected when the quick connector is pressed; the quick-connect is in a locked state when not pressed. On the one hand, the drainage bag 1 can be replaced, and on the other hand, the air tightness of the device is prevented from being damaged by false touch of a patient.

In the technical scheme of this application, the effect of drainage bag 1 is drainage liquid, and the liquid that drains out gets into drainage bag 1. When the drainage bag is full, the drainage bag can be replaced, as shown in fig. 1, the empty groove 7 only provides support for the drainage bag, the relation between the empty groove 7 and the drainage bag 1 is just like that a plastic bag is placed in a cup, the empty groove 7 is just like that of the cup, the drainage bag 1 is just like that of the plastic bag, and when the plastic bag is full, the drainage bag is taken out of the cup and replaced by a new plastic bag.

In the description of the present application, it should be further noted that, the water pressure regulating bottle 2 is different from the traditional closed thoracic drainage bottle, and the water pressure regulating bottle of the present application integrates the gas collecting bottle with the pressure regulating bottle, so that the use area is reduced, and meanwhile, the first nozzle 3 is directly communicated with the atmosphere, so that the negative pressure can be regulated. The second pipe orifice 6 is connected with the water pressure regulating bottle through a rubber ring with good sealing property, so that the air tightness is ensured, and the height can be regulated, thereby being convenient for doctors to operate. As shown in fig. 1, a drainage bag 1 and a water pressure regulating bottle 2 are connected through a U-shaped pipe 13, and pipes connected with a first pipe orifice 3 and a second pipe orifice 6 extend into the water pressure regulating bottle 2 and extend below the liquid level of the water pressure regulating bottle 2.

The bottom of the water pressure regulating bottle 2 is also connected with a rotating base 8, so that the water pressure regulating bottle can be regulated to a required angle and can play a role in good stability.

Examples

When pneumothorax/pneumothorax (needing closed drainage of thoracic cavity) occurs to a patient, a Y pipe 5 is placed at the proper rib clearance opening of the patient, the Y pipe 5 is connected with a drainage bag 1 through a straight pipe 12 and a quick connector 4, the drainage bag 1 is placed in an empty groove 7, and then the drainage can be performed by connecting with a water pressure regulating bottle 2. The water pressure regulating bottle 2 needs to put a certain amount of water into the bottle through a first nozzle 3 or a third nozzle 10 to provide negative pressure in the bottle.

The intrathoracic liquid of the patient can be drained into the drainage bag 1 through the suction interface 501 of the Y pipe, and the drainage bag 1 can be replaced after being filled with the liquid. The air in the chest cavity enters the water pressure regulating bottle 2 through the second pipe orifice 6 and is discharged into the atmosphere through the first pipe orifice 3. The pipe in the water pressure regulating bottle 2 is stretched into by the mouth of pipe 3 and mouth of pipe 6 No. two, and below the liquid level of water pressure regulating bottle 2, can adjust the relative degree of depth of mouth of pipe 3 and mouth of pipe 6 and liquid level No. two according to actual conditions, and then adjusts this application drainage device's negative pressure size.

When necessary, an external negative pressure suction pump can be connected through the third nozzle 10 to provide a larger negative pressure. When not required, the third nozzle 10 is in a closed state, and as an example, the third nozzle 10 may be closed by a cover adapted thereto. In actual use, the relative height that mouth of pipe 3 and mouth of pipe 6 stretch into the liquid level has decided the size of negative pressure, when the patient need go out the activity, can carry away the drainage device of this application through handheld pole 9, when not needing the activity, the bottom can carry out stable fixation.
