Description
Technical Field
The application relates to a medical instrument, in particular to a negative pressure drainage ball.
Background
The negative pressure drainage ball is also called as a drainage ball, is a common drainage means, and is used together with a drainage tube, and negative pressure generated in the recovery process after the drainage ball is deflated is utilized to form negative pressure suction on the drainage tube connected with the drainage ball, so that liquid in the body of a patient is drained out. The prior drainage ball is shown in fig. 1, and comprises a ball body 1 and a cover body 2; the cover 2 is formed with a first pipe 21 and a second pipe 22; the first tube body 21 is used for inserting a drainage tube; a lid 23 is openably and closably attached to the second tube. The second tube 22 is closed by its cover 23 during drainage; along with the process of drainage, drainage is also more and more in the ball body 1, and the ball body 1 is also littleer and more to the negative pressure that the drainage tube formed. It is then necessary to open the cover 23 again to force out a portion of the air in the ball body 1 and then close the cover 23 so that the negative pressure in the ball body 1 is restored. However, when the ball body 1 is compressed and air is discharged, drainage liquid is partially squeezed out and splashed on the hand of the operator, and the appearance of the drainage ball is also dirtied when the ball body 1 is compressed and air is discharged in the process of supplementing the negative pressure.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, the present application aims to provide a negative pressure drainage ball, which can prevent drainage liquid from being squeezed out together during the exhaust process.
The negative pressure drainage ball comprises a ball body and a cover body; the cover body is detachably arranged on the upper end opening of the ball body; a first pipe body and a second pipe body are formed on the cover body; the first tube body is used for being connected with the drainage tube; the second pipe body is used for discharging air in the ball body; a bracket is formed in the second pipe body, and a floating ball component is slidably mounted on the bracket;
the bracket is in a straight shape, and a through hole is formed in the center of the bracket;
the floating ball component comprises a hollow plastic ball and a smooth guide rod; the hollow plastic ball is integrally connected with the lower end of the guide rod; a stop block is formed at the upper end of the guide rod; the middle part of the guide rod is arranged in the through hole of the bracket; the diameter of the stop block is larger than that of the through hole; the hollow plastic floating ball is positioned below the second pipe body; the outer diameter of the hollow plastic floating ball is larger than the inner diameter of the lower port of the second pipe body.
Preferably, a bell-mouth-shaped guide slope is formed at the lower end of the second pipe body.
By installing a float member in the second tube, if the user squeezes too hard or too fast; the air flow or the gushing drainage liquid can jack the hollow floating ball, so that the hollow floating ball blocks the lower port of the second pipe body, and the drainage liquid is prevented from being extruded out carelessly.

Detailed Description
The negative pressure drainage ball of the present application will be described in detail below with reference to the accompanying drawings.
The application discloses negative pressure drainage ball, it includes ball body 1 and lid 2.
The cover 2 is detachably attached to the upper end opening of the ball body 1.
The cover 2 is formed with a first pipe 21 and a second pipe 22; the first tube 21 is used for connecting to a drainage tube; the second tube 22 is used for discharging air in the ball body. These are all the same as the prior art negative pressure drainage ball.
The negative pressure drainage ball of the present application is characterized in that a bracket 24 is formed in the second tube 22, and a float member is slidably mounted on the bracket 24.
The bracket 24 is formed in a line shape, and a through hole is formed at the center of the bracket 24. The straight support 24 leaves sufficient openings for the outflow of the air flow.
The floating ball component comprises a hollow plastic ball 3 and a smooth guide rod 31; the hollow plastic ball 3 is integrally connected with the lower end of the guide rod 31; a stopper 32 is formed at the upper end of the guide rod 31; the middle part of the guide rod 31 is arranged in the through hole of the bracket 24; the diameter of the stopper 32 is larger than that of the through hole; the hollow plastic floating ball 3 is positioned below the second pipe body 22; the outer diameter of the hollow plastic floating ball 3 is larger than the inner diameter of the lower port of the second tube body 22.
The lower end of the second tube 22 is formed with a bell-mouth-shaped guide slope so that the hollow ball 3 is partially inserted into the lower end opening of the second tube 22 after being jacked up, to better seal the second tube 22.
During air exhaust, if the ball body is slowly squeezed, the air flow flowing out of the second pipe body is slow, and the hollow floating ball cannot be jacked up, as shown in fig. 3; if the quick extrusion ball body or the drainage liquid is gushed after being extruded, the hollow floating ball is jacked up, as shown in figure 4, the lower end of the second pipe body is sealed, and therefore the drainage liquid cannot be splashed out.
