Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a disposable medicine-injection backflow-preventing sterile drainage device
Background
Tuberculous pleural effusion is a common and frequently occurring disease of tuberculosis. Chest puncture is commonly used clinically to puncture and withdraw hydrothorax, and pleural reaction is also common because repeated puncture increases the pain of patients and the chances of intrathoracic infection, pneumothorax and other complications. At present, most of clinically applied chest drainage tubes are single-cavity chest tubes, and only play a role in drainage. The single-cavity intrathoracic drain is not beneficial to intrathoracic injection of medicine or intrathoracic irrigation; the connection port is required to be separated repeatedly during medicine injection, so retrograde pollution is easy to cause; when the pleural effusion is continuously drained, the drainage bag is higher than the puncture point, and is easy to cause countercurrent infection.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a disposable drug-injectable anti-reflux sterile drainage device comprising: the two ends of the drainage catheter are respectively an insertion end and an exposed end, the insertion end and the exposed end are both openings, and a partition is arranged in the middle of the drainage catheter and is divided into a medicine injection cavity and a drainage cavity. The drainage cavity is provided with a front opening at the insertion end of the drainage tube, a left opening and a right opening are respectively arranged at two sides of the drainage tube, and a one-way valve is arranged at the exposed end of the drainage cavity; the upper side and the left side of the medicine injection cavity are respectively provided with an upper opening and a left opening, a one-way valve is arranged at the opening at the left lower side of the medicine injection cavity, and the exposed end is provided with a positive pressure type screw joint.
The exposed end of the drainage tube is provided with a front opening, and the two sides of the drainage cavity are respectively provided with a left opening and a right opening; the upper and left sides of the medicine injection cavity are respectively provided with an upper opening and a left opening, and all the openings adopt asymmetric openings to realize multi-direction and multi-plane drainage and medicine injection.
The drainage cavity and the medicine injection cavity are internally provided with one-way valves.
The disposable drug-injection anti-reflux sterile drainage device has the advantages that the exposed end of the drainage cavity can be connected with the drainage bag, so that the effect of drainage effusion is achieved; the exposed end of the medicine injection cavity is provided with a positive pressure device, the screw joint can realize needleless connection with the injector, the occurrence of needle puncture injury is reduced, and simultaneously, medicine injection and chest cavity flushing are convenient.
The beneficial effects of the utility model are as follows: simple structure, convenient use, safety, sanitation and good effect.

Detailed Description
Specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present utility model.
See fig. 1: a disposable medicine-injection backflow-preventing sterile drainage device comprises a medicine injection cavity 1 and a drainage cavity 2, and adopts a tube with two cavities, thereby facilitating drainage of effusion and medicine injection.
The exposed end of the drainage cavity 2 is designed to be a drainage cavity spiral connector 9 which can be connected with a drainage bag spiral connector 8 to play a role in drainage of effusion; the exposed end of the medicine injection cavity 1 is provided with a positive pressure device 10, the screw joint 11 can realize needleless connection with an injector, the occurrence of needle puncture is reduced, and simultaneously, medicine injection and chest cavity flushing are convenient.
The opening of the insertion end of the drainage tube and the asymmetric openings 3 on the left side and the right side of the drainage tube; realize diversified and many plane drainage hydrops, reduce stifled tub risk.
An asymmetric opening 4 on the upper side and the left side of the medicine injection cavity; avoiding the mixing of the medicine and the effusion and reducing the medicine effect.
The rear part of the medicine injection cavity 1 and the drainage cavity 2 is separated from the fixer 5; reduce the tube blockage caused by bending of the drainage tube.
A one-way valve 6-1 is arranged in the opening at the left lower part of the medicine injection cavity; the pressure generated by the liquid back-flowing is utilized to enable the one-way valve to be closed so as to prevent the effusion from flowing out of the medicine injection cavity.
The tail end of the drainage cavity is provided with a one-way valve 6-2; so as to prevent the infection caused by the countercurrent back-flow of the effusion in the drainage bag of the patient under the action of the one-way valve.
