Abstract

A drainage device includes a drainage tube 1, and the drainage bag 5 connected with the drainage tube 1; the drainage tube 1 is connected with the balloon 2 in series; the balloon is provided with the inner cavity 12 of the balloon; one end of the balloon 2 is provided with a third one-way valve 16; the other end of the balloon 2 is provided with a second one-way valve 15. When the balloon is pressed, the liquid can flow from the drainage tube into the drainage bag in one way; thus the device can not only bear the pressure and drain, but also can prevent the accumulated liquid from flowing into the human body; the device can drain the accumulated liquid such as the gore and other liquids which can not naturally drain.

Description

Drainage system

Technical field

This utility model relates to a kind of medical equipment, particularly the drainage system that the intravital hydrops of people is carried out drain.

Background technology

In the prior art, drainage system comprises drainage tube, the drainage bag that is connected with drainage tube, and described drainage tube is inserted in the abdominal cavity of human body for example, carries out the nature drain by drainage tube, flow at last in the drainage bag, but this drainage system can not drain human body hydrops such as clot, pus and blood.

Summary of the invention

The purpose of this utility model is to provide a kind of drainage system with bigger suction.

The technical solution of the utility model is: a kind of drainage system comprises drainage tube, the drainage bag that is connected with drainage tube; Be serially connected with balloon on the described drainage tube, described balloon has the balloon inner chamber, is provided with the 3rd check valve in an end of balloon, is provided with second check valve in the other end of balloon.

This utility model compared with prior art has following advantage:

When pushing balloon, can make that fluid is unidirectional to be entered the drainage bag from drainage tube, the effect of existing negative pressure drainage has again to prevent that hydrops from pouring the effect that enters human body into, can to clot etc. can not natural drain hydrops carry out drain.

The specific embodiment

Referring to accompanying drawing, a kind of drainage system comprises drainage tube 1, the drainage bag 5 that is connected with drainage tube 1; It is characterized in that: be serially connected with balloon 2 on the described drainage tube 1, described balloon 2 has balloon inner chamber 12, is provided with the 3rd check valve 16 in an end of balloon 2, is provided with second check valve 15 in the other end of balloon 2.Described the 3rd check valve 16, second check valve 15 all are arranged in the described balloon inner chamber 12 and with the end of drainage tube 1 and are connected, and two check valves only allow fluid to flow to the bottom from the top of accompanying drawing 2.Referring to accompanying drawing 4, described the 3rd check valve 16 is involuted by two the 3rd valve blocks 13 that are connected, one end of the 3rd valve block 13 is fixed on the end or drainage bag 5 of drainage tube 1, the other end of the 3rd valve block 13 is a free end, this free end is arranged in balloon inner chamber 12, and this free end can be opened or close, when not having fluid to flow through this check valve, free end is subjected to the pressure of balloon inner chamber 12 and is in closed state

Referring to accompanying drawing 5, described second check valve 15 is involuted by two second valve blocks 14 that are connected, one end of second valve block 14 is fixed on the end or drainage bag 5 of drainage tube 1, and the other end of second valve block 14 is a free end, and this free end is arranged in the tube chamber of drainage tube 1.Its unidirectional reason is identical with the 3rd check valve 16.Be connected with discharging tube 6 on the described drainage bag 5, discharging tube 6 is connected with drainage bag 5, and this discharging tube 6 is provided with stop valve 7.

Be connected with bleeder pipe 3 on the described drainage bag 5, be connected with on this bleeder pipe 3 and be provided with vent valve 4, after vent valve 4 is opened, can discharge the gas in the drainage bag 5.

Referring to accompanying drawing 3, in the described drainage bag inner chamber 9, drainage tube 1 is provided with first check valve 10 with the oral area that is connected of drainage bag 5.Described first check valve 10 is involuted by two thin film 11 that are connected, and an end of thin film 11 is fixed on the end or drainage bag 5 of drainage tube 1, and the other end of thin film 11 is a free end, and this free end is arranged in drainage bag inner chamber 9.This first check valve 10 also plays the effect that the liquid that prevents in the drainage bag 5 refluxes to human body.
