Description

Technical Field

[0001] The utility model relates to a gas supply transfer device for an endoscope device. Background Art

[0002] An endoscope device includes an endoscope and a water injection bottle. The water injection bottle includes a bottle body and a bottle cap, and a connecting pipe and a connector are arranged on the bottle cap. The connecting pipe and the connector are connected between the endoscope and the water injection bottle, so that the gas and liquid in the water injection bottle are input into the endoscope through the connecting pipe and the connector, providing liquid and gas for the endoscope during observation, diagnosis, and treatment.

[0003] In order to cope with different working scenarios, existing endoscopes need to replace different water injection bottles. Some water injection bottles are pre-filled with a certain amount of gas, and the amount of gas in them is fixed after filling, and it is impossible to continuously supply gas or switch to other gases. Some water injection bottles have an air inlet connected to an on-line gas supply system, but only one kind of gas can be supplied on-line, and it is impossible to quickly and effectively switch gases. Since the bottle cap of the water injection bottle is connected with the connecting pipe and the connector, the bottle cap, the connecting pipe and the connector are generally integrated. If different water injection bottles need to be replaced, it means that a set of components including the bottle cap, the connecting pipe and the connector of the water injection bottle need to be replaced. The connecting pipe and the connector are delicate components with gas and liquid pipelines and are connected to the endoscope, with a high purchase cost and involving disassembly and connection with the endoscope, which brings inconvenience to users.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: An air supply transfer device for an endoscope device, including a water injection bottle. The water injection bottle includes a bottle body and a bottle cap. The bottle body has a bottle mouth. The bottle cap is connected with a connecting pipe. The connecting pipe has a water outlet pipe and an air outlet pipe inside. One end of the water outlet pipe close to the bottle cap is connected with a water guiding pipe. It further includes an air supply adapter. The air supply adapter includes a male connector, a connecting part and a female connector connected in sequence. The male connector has an external thread. The bottle cap of the water injection bottle has an internal thread. The male connector is threadedly connected with the bottle cap of the water injection bottle. The female connector has an internal thread. The bottle mouth of the bottle body has an external thread. The female connector is threadedly connected with the bottle mouth of the bottle body. The connecting part is tubular and both ends of the connecting part are communicated with the male connector and the female connector respectively. A through hole is opened on the side surface of the connecting part. An air vent connector is hermetically fixed in the through hole. The air vent connector is a Luer connector. The Luer connector includes a female Luer connector and a male Luer connector. The female Luer connector and the male Luer connector are matched and connected with each other. The air outlet pipe is communicated with the air supply adapter. The water guiding pipe extends into the bottle body. A sealing ring is provided on the male connector. The male connector is hermetically connected with the bottle cap of the water injection bottle through the sealing ring.

[0006] The female Luer connector is fixed in the through hole of the connecting part.

[0007] Both the female Luer connector and the male Luer connector are metal connectors. The male connector, the connecting part and the female connector are integrally formed of plastic material.

[0008] The beneficial effect of the present utility model is that an air supply transfer device for an endoscope device of the present utility model does not need to replace the existing water injection bottle, including the bottle cap of the water injection bottle, the connecting pipe and the connector. On the basis of the original water injection bottle, only an air supply adapter needs to be added to realize the air supply transformation of the water injection bottle. For example, through the air supply adapter, the fixed-capacity air supply can be changed to the on-line air supply state, or a new on-line air delivery pipeline can be added on the original basis to facilitate the rapid and effective switching of gases.
