Example two
The embodiment is a method for monitoring a drainage catheter according to the first application, including the steps of:
after the operation of the patient, the drainage catheter is implanted into the part needing drainage by selecting the drainage position of the patient according to the specific condition of the patient by a doctor. At this time, the tip of the catheter on the insertion port 8 is inserted into the tissue of the human body, the drainage catheter body 1 extends to the outside of the body along the inside of the human body, and the liquid receiving tube 9 is vertically arranged outside the body.
For the state of an illness of different patients, drainage pressure is different, doctors need to input corresponding state of an illness data in advance according to the state of an illness of the patients and actual conditions, corresponding applications test the pressure of the corresponding state of an illness in advance according to a corresponding database, the relation between the state of an illness and pressure difference is obtained, and therefore the doctors can directly input parameters related to the state of an illness to monitor.
The head end pressure sensor and the tail end pressure sensor collect pressure values at preset intervals and transmit the pressure values to the main control unit, and the preset intervals can be set to be different in seconds or minutes according to actual conditions.
The main control unit calculates the difference between the pressure values acquired by the head end pressure sensor and the tail end pressure sensor in real time to obtain a pressure difference value; the main control unit monitors the drainage condition according to the differential pressure value, and the method specifically comprises the following steps:
1) when the differential pressure value is a first positive value, the drainage of the drainage catheter is normal. When normal drainage, the pressure value that head end pressure sensor gathered is the osmotic pressure of human tissue hydrops, and the pressure value that tail end pressure sensor gathered is 0 almost, and consequently, the pressure value that head end pressure sensor gathered will be greater than the pressure value that tail end pressure sensor gathered, so when normal drainage, the differential pressure value slightly is greater than 0 and is first positive value. At this time, the amplitude of the variation of the differential pressure value is relatively flat, which represents that the effusion in the patient is normally discharged outwards.
2) When the differential pressure value is equal to 0, the accumulated liquid in the body is emptied, and the drainage catheter is empty.
3) When the differential pressure value is a second positive value and is greater than the first positive value, or is a negative value, the drainage catheter is blocked.
In addition, when the differential pressure value is switched back and forth between a state slightly larger than 0 and a state equal to 0, the accumulated liquid in the body is about to be emptied.
In order to further confirm the jam position, the present embodiment may be further modified as follows:
1) when the differential pressure value is a second positive value and is greater than the first positive value, the pipeline above the tail end pressure sensor is blocked. That is, as shown in fig. 1, when the drainage catheter is draining normally, the differential pressure value is slightly larger than 0. When pipeline takes place to block up above tail end pressure sensor promptly and takes place to block up more than the B section, tail end pressure sensor can not gather the pressure value, and B section liquid is overstocked more this moment, and the differential pressure value slowly increases, and liquid is in case it is full of A section pipeline to exceed head end pressure sensor, and the pressure value that head end pressure sensor gathered this moment will reach the maximum value, and the differential pressure value also can become the maximum value, and the differential pressure value after the change this moment is called the differential pressure value second positive value, and the second positive value is greater than first positive value this moment. The blockage of the section B is most easy to occur, and the section B is longer, so that the drainage is not smooth due to the fact that the section B is most easily pressed by the hand of a patient or other foreign matters, and doctors often give advice to accompany family members to see the drainage catheter when the drainage is carried out.
2) If the differential pressure value is a negative value, the blockage of a pipeline below the tail end pressure sensor is indicated (as shown in a section C part in fig. 1), and at the moment, no liquid flows in the drainage catheter body; when C section blocks up and is full of liquid above the position, head end pressure sensor and tail end pressure sensor homoenergetic gather the pressure value, and the pressure value that tail end pressure sensor gathered is greater than the pressure value that head end pressure sensor gathered this moment, and the differential pressure value will become the negative value. And the differential pressure value will also become negative when the receiving bag is full, i.e. the liquid fills the entire conduit.
Preferably, the main control unit is provided with a pressure difference alarm device, and when the pressure difference value is a second positive value or a negative value, the pressure difference alarm device gives an alarm.
Preferably, the main control unit is connected with a nurse workstation, and when the pressure difference alarm device gives an alarm, the nurse workstation responds to an alarm signal.
Preferably, the main control unit is connected with a terminal carried by a patient, and the terminal responds to an alarm signal when the pressure difference alarm device gives an alarm.
The invention can accurately infer the illness state treatment condition of the patient by accurately measuring the flow and the blockage of the drainage effusion, determine the treatment effect in time and take corresponding measures. The treatment scheme is corrected and improved according to the corresponding monitoring condition, so that the patient can more accurately master the condition of the patient, the understanding degree of the doctor and the patient is improved, the problem of distrust of the patient due to information asymmetry is avoided, and the relationship between the doctor and the patient is improved.
The present invention is not limited to the specific technical solutions described in the above embodiments, and other embodiments may be made in the present invention in addition to the above embodiments. It will be understood by those skilled in the art that various changes, substitutions of equivalents, and alterations can be made without departing from the spirit and scope of the invention.
