[0006] Preferably, the metering sampler includes a connector and a sampling bottle, a T-shaped hole is provided in the sealing cover, a connector is movably installed in the T-shaped hole, the connector is in the shape of a hollow sleeve, and the connector opens downward, a connecting hole is provided on the top of the connector, and a sampling bottle is detachably installed on the bottom of the connector.

[0007] Preferably, the inner wall of the connector is processed with an internal thread, the top of the sampling bottle is processed with an external thread, and the sampling bottle is threadedly connected to the connector.

[0008] Preferably, scale lines are processed on the outside of the sampling bottle, and the units of the scale lines are ML.

[0009] Preferably, a slide groove is provided in the sealing cover, and two slide grooves are provided. The two slide grooves are symmetrically arranged, and the slide grooves are connected to the T-shaped hole. A slide plate is fixedly installed on the outside of the connector, and a buffer spring is fixedly installed above the slide plate, and the top of the buffer spring is fixedly connected to the inner wall of the slide groove.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model discloses a contactless metering drainage device, which can sample and measure the body fluid in the drainage bag. During the sampling and metering process, the body fluid does not directly contact with the outside world, thereby avoiding contamination and improving the metering accuracy.

[0017] See also Figure 1-4 The utility model provides a technical solution: a contactless metering drainage device, including a drainage bag 1, a drainage tube 2 is fixedly installed at the top of the drainage bag 1, a discharge pipe 3 is fixedly installed below the drainage bag 1, a sealing cover 5 is fixedly installed at the bottom of the discharge pipe 3, and a metering sampler 4 is movably installed in the sealing cover 5.

[0018] Furthermore, the metering sampler 4 includes a connector 6 and a sampling bottle 7. A T-shaped hole 8 is opened in the sealing cover 5. The connector 6 is movably installed in the T-shaped hole 8. The connector 6 is in the shape of a hollow sleeve, and the connector 6 opens downward. A connecting hole 9 is opened on the top of the connector 6, and a sampling bottle 7 is detachably installed on the bottom of the connector 6.

[0019] Furthermore, the inner wall of the connector 6 is processed with an internal thread, the top of the sampling bottle 7 is processed with an external thread, and the sampling bottle 7 is threadedly connected to the connector 6.

[0020] Furthermore, scale lines are processed on the outside of the sampling bottle 7, and the unit of the scale lines is ML.

[0021] Furthermore, a slide groove 10 is opened in the sealing cover 5, and there are two slide grooves 10. The two slide grooves 10 are symmetrically arranged, and the slide groove 10 is connected to the T-shaped hole 8. A slide plate 12 is fixedly installed on the outside of the connector 6, and a buffer spring 11 is fixedly installed above the slide plate 12. The top of the buffer spring 11 is fixedly connected to the inner wall of the slide groove 10.

[0022] Working principle:

[0023] When in use, first insert the drainage tube 2 into the patient's body, and the body fluid enters the drainage bag 1 through the drainage tube 2. When it is necessary to sample or discharge the body fluid, push the sampling bottle 7 upward, and the sampling bottle 7 pushes the connector 6. A slide plate 12 is provided on the outside of the connector 6, and the slide plate 12 squeezes the buffer spring 11. When the connecting hole 9 on the outside of the connector 6 enters above the sealing cover 5, it is connected with the discharge pipe 3. At this time, the body fluid enters the sealing cover 5 through the discharge pipe 3, enters the connector 6 through the connecting hole 9, and enters the sampling bottle 7 through the connector 6 again. When the sampling discharge or sampling is completed, release the sampling bottle 7. At this time, the connector 6 is reset under the action of the buffer spring 11. At this time, the connecting hole 9 is separated from the discharge pipe 3 to ensure its air tightness. At the same time, a scale line is provided on the outside of the sampling bottle 7, which can accurately measure the discharged body fluid and sample and measure the body fluid in the drainage bag 1. During the sampling and measuring process, the body fluid does not directly contact with the outside world to avoid contamination and improve the measuring accuracy.
