Description
Technical Field
The invention belongs to the field of medical appliances, and particularly relates to a device capable of automatically controlling drainage quantity.
Background
The drainage method is widely used clinically, one or more porous catheters connected with a drainage bag are placed into a wound cavity or a body cavity, and the effusion in the cavity is automatically led out into the drainage bag, so that the infection can be prevented, the compression of adjacent organs and tissues can be relieved, the symptoms can be improved, and the wound healing can be promoted. Together, a large number of documents based on clinical experience and search indicate that: intermittent and quantitative drainage is very important in the process of external drainage of accumulated liquid. For example, a large amount of too fast drainage of pleural effusion can lead to renaturing pulmonary edema and mediastinal swing, and excessive drainage of peritoneal effusion can lead to sudden drop of abdominal pressure, inducing hepatic encephalopathy. In addition, the incidence of leakage of cerebrospinal fluid after spinal surgery is about 10%. The occurrence causes are more, and the occurrence causes are mainly related to iatrogenic operation, potential pathological factors of dura mater, adhesion between dura mater and surrounding tissues and the like. The main manifestation is that the drainage volume after operation is abnormally increased, and the drainage volume is light red blood liquid or clear liquid. Patients show symptoms of low craniocerebral pressure such as headache, dizziness, nausea and vomiting. Clinically, non-operative treatment is mainly performed on the postoperative cerebrospinal fluid leakage, usually, head and foot rest is adopted for high lying, fluid replacement is enhanced, drainage volume is controlled every day, and clamping should be performed after a certain drainage volume is reached. Avoid the excessive loss of cerebrospinal fluid due to excessive drainage, and further aggravate the symptom of low craniocerebral pressure. In addition, excessive drainage can even cause severe complications such as epidural hemorrhage, cerebral hernia and the like, and endanger the life of patients. Meanwhile, the drainage tube is intermittently clamped by controlling the drainage quantity, cerebrospinal fluid can flow out to surrounding tissues during clamping, and after the pressure of the tissues rises to reach the pressure in the vertebral canal, the dura mater port can be closed, so that the dura mater healing is promoted.
At present, a negative pressure drainage ball is generally used as a drainage device for wounds or body cavity effusion in clinic, and meanwhile, the tail end of the negative pressure drainage ball can be connected with a liquid collecting bag with scales for counting drainage amount every day. Or SB drainage bags are adopted as wound drainage devices, but the drainage devices are only used for drainage of blood and liquid, and the problems of controlling drainage speed and drainage rate are not considered. As such, there are the following drawbacks:
1. the drainage amount of each day cannot be automatically controlled, and meanwhile, the drainage bag is difficult to observe because the drainage bag is suspended at a low position. The medical staff, the patients and the families are overstressed, the medical staff needs to check the drainage quantity irregularly and repeatedly, and the medical staff is manually clamped after a certain quantity is reached, so that time and energy are wasted.
2. If postoperative wound or intracavity effusion are infected, single tube irrigation and drainage cannot be performed on the wound or intracavity effusion in time, once local infection of the wound cannot be controlled, the infection can spread and spread to adjacent tissues and organs. For example, in the presence of leakage of cerebrospinal fluid from a spinal post-operative wound, bacteria and viruses may retrograde to the central nervous system if the wound is infected, resulting in a central infection.
3. The negative pressure of the drainage device cannot be detected, so that the drainage speed is easily excessive or insufficient, and corresponding complications are caused.

Step 3: when the drainage liquid reaches 300ml, the floating ball 12 is lifted by buoyancy, the circuit is disconnected under the action of the return spring after the gravity action of the floating ball is lost by the regulating knife, and the telescopic rod retracts to drive the movable clamp and the fixed clamp to close and clamp the drainage tube.
Step 4: the next morning, drain liquid is discharged from liquid outlet 13, after the discharge, floater 12 receives self gravity subsidence only again for adjusting knife 25 closure, and the circuit starts, and hydraulic electric putter 23 promotes the removal clamp 9 and moves rightwards, compresses first return spring 22, opens the drainage tube 1 of being clamped, begins the drainage of the next day.
Note that after several days, the drainage amount is reduced, and when the control of excessive drainage amount is not needed, the starting switch 24 can be closed, and only negative pressure is used for continuous drainage; if drainage is not needed temporarily, the three-way valve 2 is closed while the start switch 24 is closed.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
