Automatic hematoma flushing device

Abstract

The invention discloses an automatic hematoma flushing device which is specifically used by the following steps: 1) respectively connecting an infusion tube with a balloon and a normal saline infusion bottle containing urokinase, connecting the infusion tube at the lower end with a tee joint, and respectively connecting the other two ends of the tee joint with a negative pressure drainage bottle and hematoma to be flushed; (2) respectively fixing three valves on an infusion tube, fixing a balloon, an eccentric wheel and the like together, and switching on a power supply of a control panel; in the rotating process of the eccentric wheel, continuously extruding the balloon to change the volume of the balloon, so that the pressure periodically changes; (3) by changing the opening and closing conditions of the three valves, indicating the balloon filled with the flushing fluid flushes the hematoma of the patient, after balance is achieved, carrying out negative pressure drainage and starting ratistathe next cycle when the drainage flushing fluid is almost too much. The invention has the advantages that periodic pressure is generated through rotation of the eccentric wheel, flushing liquid and hematoma are fully mixed, the hematoma is dissolved, dissolved liquid is drained out through the negative pressure drainage bottle, and therefore the purpose of removing the hematoma is achieved. As the liquid in the infusion tube inserted into the hematoma flows all the time, blood coagulation can be avoided, the infusion tube is prevented from being blocked, and drainage failure is avoided. By means of the three electronic valves, closing and opening of the infusion tube are achieved, and the purpose of control is achieved.

Description

technical field [0001] Disclosed is an automatic hematoma flushing device for clinical treatment, especially for cerebral hemorrhage and other related diseases. Background technique [0002] At present, in my country, for hematomas, especially those in a static state, conservative treatment is used for small ones, allowing the hematoma to absorb itself, while for large ones, manual irrigation and drainage or surgical treatment are used. For larger hematomas, if a puncture tube is used to flush manually, it is not only time-consuming and laborious, but also cannot be flushed cleanly, and the space-occupying problem of the hematoma is not completely solved. At the same time, for bleeding in some key parts, such as cerebral hemorrhage, the external pipeline should not be too thick, which may easily cause iatrogenic injury to the patient. Due to the problem of pipe diameter, the flushing pipe and the drainage pipe must be the same, and the smaller pipe diameter is likely to cau...

Problems solved by technology

For larger hematomas, if puncture tubes are used to flush manually, it is not only time-consuming and labor-intensive, but also cannot be washed cleanly, and the space-occupying problem of hematoma is not completely solved.

At the same time, for bleeding in some key parts, such as cerebral hemorrhage, the external pipeline should not be too thick, which may easily cause iatrogenic injury to the patient

Due to the diameter of the pipe, the flushing pipe and the drainage pipe must be the same, and the smaller pipe diameter is likely to cause blockage of the drainage pipe
