Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1-3, a puncture drainage device includes a puncture element 1 and a drainage mechanism 2.

Wherein, puncture piece 1 includes a puncture section of thick bamboo 11 and pjncture needle 12, and pjncture needle 12 can pierce in the hydrops of skin 3, and a puncture section of thick bamboo 11 and the sealed intercommunication of the bottom of pjncture needle 12 of passing through the screw thread rotation, the inside of a puncture section of thick bamboo 11 is equipped with negative pressure passageway 13 and drainage channel 14, and negative pressure passageway 13 is located one side of drainage channel 14, and the bottom and the drainage channel 14 of negative pressure passageway 13 communicate, and drainage channel 14 communicates with pjncture needle 12.

The drainage mechanism 2 comprises a negative pressing part 21 and a drainage tube 22, the negative pressing part 21 is detachably mounted at a channel opening of the negative pressure channel 13, the channel opening is far away from the puncture needle 12, the negative pressing part 21 can generate negative pressure to enable the drainage channel 14 to generate negative pressure, and the drainage tube 22 is fixedly communicated with the drainage channel 14. Specifically, the negative pressure part 21 includes a first one-way valve 211, the capsule body 212 and a communication valve 213, the first one-way valve 211 is fixedly installed in the negative pressure channel 13, the capsule body 212 is detachably installed at a top channel opening of the drainage channel 14 in an adhesion manner, and during operation, the capsule body 212 is in a squeezing state, so that the drainage channel 14 generates negative pressure. When the hydrops in the patient body is extracted, after the balloon 212 is expanded, the puncture needle 12 generates suction to the hydrops, so that the hydrops at the end of the puncture needle 12 enters the drainage channel 14, and the first one-way valve 211 blocks the gas or liquid in the balloon 212 from entering the negative pressure channel 13. Meanwhile, a liquid outlet is formed in the side wall of the bag body 212, and the communication valve 213 is fixedly installed in the liquid outlet. Opening communication valve 213 facilitates more rapid squeezing of bladder 212 and in turn allows for timely drainage of accumulated fluid entering bladder 212.

In this embodiment, referring to fig. 1 and fig. 3, in order to better store the effusion, the drainage mechanism 2 further includes a second one-way valve 23, a drainage bag 24 and a fixing adhesive tape 25. The second one-way valve 23 is fixedly installed in the pipeline of the drainage tube 22. The second one-way flap 23 prevents external air from entering the drainage tube 22, and prevents the patient from being infected during drainage. Meanwhile, the drainage bag 24 is communicated with the drainage tube 22; drainage bag 24 can be better to the collection that concentrates of hydrops. The fixing adhesive tape 25 is adhered to part of the outer surface of the drainage bag 24, and the two end parts of the fixing adhesive tape 25 extend out of the bag surface of the drainage bag 24, so that the fixing adhesive tape 25 is adhered to the skin 3 of a patient or a hospital bed, and the drainage bag 24 is fixed.

When the utility model is used, the puncture needle 12 is punctured into the skin 3 of a patient, the puncture needle 12 enters into effusion, the drainage bag 24 is placed on the body of the patient or a sickbed, the drainage bag 24 is positioned at the lower part of the effusion, and the drainage bag 24 is fixed by the fixing adhesive tape 25; so that the effusion passes through the puncture needle 12 and enters the drainage channel 14, and the effusion in the drainage channel 14 enters the drainage tube 22 and is discharged through the drainage tube 22. When the needle point of the puncture needle 12 is partially blocked, the capsule body 212 is pressed, the capsule body 212 generates negative pressure suction to suck the blockage in the puncture needle 12, and then the blockage in the body of the patient is sucked into the puncture cylinder 11 and is discharged through the drainage tube 22, so that the drainage effect of the accumulated liquid is improved. The drained accumulated liquid is collected in a centralized way through a drainage bag 24; thereby realizing better liquid drainage for the volume in the body of the patient.

The above technical scheme is that the negative pressure channel 13, the drainage channel 14, the negative pressure piece 21 and the drainage tube 22 are arranged. The pipeline of the drainage tube 22 is pressed, the negative pressing piece 21 generates negative pressure suction, the blockage at the puncture needle 12 is sucked, and then the blockage in the patient body enters the puncture cylinder 11 and is discharged through the drainage tube 22. Thereby avoiding blockage of the needle head of the puncture needle 12 and achieving better drainage of the fluid in the body of the patient.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
