Abstract
The invention discloses a drainage pack adapter assembly which comprises an adapter, an adapter rear cover and an anti-countercurrent block piece, wherein a drainage channel, an injection syringe connector and an adapter connection part are arranged on the adapter; an injection channel is arranged in the injection syringe connector; the adapter rear cover is provided with a connection slot and a connection pipe adapter; the anti-countercurrent block piece comprises a fixing ring and a flowing blocking piece; the flowing blocking piece is arranged at the inner side of the fixing ring; the fixing ring and the flowing blocking piece are connected by a connection arm; the adapter connection part and the anti-countercurrent block piece are arranged in the connection slot of the rear cover; the adapter connection part presses the fixing ring on the bottom end of the connection slot; the flowing blocking piece covers a through hole of the connection pipe adapter. According to the drainage pack adapter assembly, the combination of the adapter, the adapter rear cover and the anti-countercurrent block piece is used, so that the anti-countercurrent block piece has a one-way flow blocking function, and the phenomenon that medicine liquid flows into a drainage pack from the connection pipe adapter of the adapter rear cover when the medicine liquid is injected from the injection syringe connector can be prevented.
Description
Technical field
The present invention relates to a kind of drainage bag adapter assembly, particularly a kind ofly can prevent that the injection drug aqueous reflux from entering the drainage bag adapter assembly of drainage bag, belongs to technical field of medical instruments.
Background technology
When using drainage bag to process wound or privileged sites, usually need to inject liquid medicine by the syringe interface on the joint of drainage bag cleans, the joint of general drainage bag is when injection liquid medicine, use very inconvenient, even can produce the phenomenon that liquid medicine flows backwards and enters drainage bag, cause great inconvenience for doctor and patient.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind ofly can prevent that the injection drug aqueous reflux from entering the drainage bag adapter assembly of drainage bag.
Technical solution of the present invention is achieved in that a kind of drainage bag adapter assembly, comprises joint, joint bonnet and counterflow-preventing catch; In described joint, be provided with drainage channel, the sidepiece of joint is provided with syringe interface, and the rear end of joint is provided with the joint connecting portion; In described syringe interface, be provided with the injection canal be connected with drainage channel; The front end of described joint bonnet is provided with link slot, and the rear end of joint bonnet is provided with the connection tube joint; Described counterflow-preventing catch comprises retainer ring and spoiler; Described spoiler is arranged on the inboard of retainer ring; Described retainer ring is connected by linking arm with spoiler; Described joint connecting portion and counterflow-preventing catch all are arranged in the link slot of bonnet; Described joint connecting portion is pressed on retainer ring the bottom of link slot; Described spoiler covers on the through hole of connection tube joint.
Preferably, described syringe interface is inclined to set, the centrage out of plumb of the centrage of syringe interface and joint; The interface of described syringe interface is towards the rear end of joint.
Preferably, the external diameter of described joint starts the increase of saltatory ground from the front end of joint, forms the round platform of a plurality of stepped distributions.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Drainage bag adapter assembly of the present invention, utilize the combination of joint, joint bonnet and counterflow-preventing catch, makes the counterflow-preventing catch have the effect of unidirectional choked flow, and while preventing from injecting liquid medicine from syringe interface, liquid medicine flows into drainage bag from the connection tube joint of joint bonnet; And the liquid medicine that accidentally flows to drainage bag can also refund joint under the effect of the unidirectional choked flow of counterflow-preventing catch in.
