Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1 to 4, the utility model comprises a negative pressure drainage ball 1 for drainage and containing exudate and an exhaust group 2 arranged on the negative pressure drainage ball 1 and used for exhausting the gas in the negative pressure drainage ball 1. The exhaust group 2 comprises an air outlet which is arranged on the negative pressure drainage ball 1 and is communicated with the inside of the negative pressure drainage ball 1 and a pipe plug 22 which is arranged on the air outlet and is used for plugging the air outlet, and a first pull rope 6 for preventing the pipe plug 22 from being lost is arranged between the air outlet and the pipe plug 22. When negative pressure drainage ball 1 needs the drainage, medical personnel take off stopcock 22 from the gas outlet, extrude negative pressure drainage ball 1 and make the inside air of negative pressure drainage ball 1 discharge through gas vent 21, then use stopcock 22 to block up gas vent 21, make the inside negative pressure that forms of negative pressure drainage ball 1 from this.

Further referring to fig. 1 to 3, the negative pressure drainage ball 1 is provided with a drainage group 3 for draining the exudate, the drainage group 3 comprises a drainage port 31 which is arranged on the negative pressure drainage ball 1 and is communicated with the inside of the negative pressure drainage ball 1, a drainage main pipe 32 which is sleeved on the drainage port 31, and a branched joint 33 which is arranged at the output end of the drainage main pipe 32, and the branched joint 33 is a Y-shaped three-way joint. Two branch drainage tubes 34 for draining penetrating fluid in the body of a patient are arranged on the branched joint 33, one end of the branched joint 33 is communicated with the main drainage tube 32, and the other two ends of the branched joint 33 are respectively communicated with the branch drainage tubes 34. The drainage branch pipe 34 is provided with a skin puncture 5, and the skin puncture 5 is made of medical stainless steel. The puncture 5 is provided with a protective cap 10, and the protective cap 10 is used for preventing the puncture 5 from stabbing medical staff when not in use.

Further referring to fig. 1 and 3, a valve 4 for controlling the on-off of the main drainage pipe 32 is arranged on the main drainage pipe 32, a check valve 7 is arranged on the main drainage pipe 32 and between the valve 4 and the drainage port 31, the flowing direction of the check valve 7 is from the drainage branch pipe 34 to the negative pressure drainage ball 1, and the check valve 7 is used for preventing the seepage in the negative pressure drainage ball 1 from flowing backwards and entering the body of a patient to cause infection in the treatment process.

Further referring to fig. 1, the outside of the negative pressure drainage ball 1 is provided with scales 9 for medical staff to observe the amount of the exudate in the negative pressure drainage ball 1. Still be equipped with the fixing device 8 that is used for fixed negative pressure drainage ball 1 on the negative pressure drainage ball 1, fixing device 8 is including setting up second stay cord 81 on negative pressure drainage ball 1 and setting up fixation clamp 82 on second stay cord 81, and medical personnel's accessible fixation clamp 82 presss from both sides tight object and fixes negative pressure drainage ball 1.

When the patient need the drainage, medical personnel at first take off the stopcock 22 of the gas vent 21 on the negative pressure drainage ball 1, close drainage manifold 32's valve 4, extrude negative pressure drainage ball 1 after that, pass through gas vent 21 with the inside air of negative pressure drainage ball 1 and discharge, utilize stopcock 22 shutoff gas vent 21, make the inside negative pressure that forms of negative pressure drainage ball 1. Then the protective cap 10 is taken down and the two drainage branch tubes 34 are placed in two different positions or cavities of the operation area, wound closing and wound suturing are carried out, the valve 4 on the drainage main tube 32 is opened, and the exudates can flow into the negative pressure drainage ball 1 along with the negative pressure attraction force.

When the accumulated liquid flowing into the negative pressure drainage ball 1 is large, the negative pressure attraction force is weakened, and the effusion in the negative pressure drainage ball 1 needs to be poured. At this moment, the valve 4 on the drainage main pipe 32 needs to be closed, then the drainage main pipe 32 is taken down from the negative pressure drainage ball 1, the penetrating fluid in the negative pressure drainage ball 1 is dumped, then the air in the negative pressure drainage ball 1 is extruded, then the negative pressure drainage ball 1 is connected with the drainage main pipe 32 again, the air outlet 21 is blocked, and the valve 4 is opened, so that a new negative pressure drainage environment is formed.

The above description is only for the preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
