the air supply assembly comprises an air pipe 1, the air pipe 1 is connected with a first valve 5, the first valve 5 is connected with an air chamber 6, the air chamber 6 is connected with a second valve 4, and the second valve 4 is connected with an air suction opening 3.
The air chamber 6 is connected with the air blowing port 2.
The outside of the storage chamber 10 is connected with a third valve 9, the third valve 9 is connected with a storage bottle 19, and the inside of the storage bottle 19 is provided with physiological saline.
The electronic flow meter 12 is provided with a first flow sensor 11.
The electronic flow meter 12 is provided with a second flow sensor 13.
It should be noted that, at the in-process of patient postoperative drainage, when the drainage tube blockked up, at first, slowly extract remaining liquid in the drainage tube through extraction opening 2, the inside liquid of drainage tube also has pressure this moment, when extracting liquid, slowly extracts, extracts many times in the process, avoids suction too big, injures the human body for liquid is taken out from extraction opening 2. At this time, the inside of the drainage tube is in a liquid-free state, the second control valve 17 is closed, the physiological saline stored in the storage bottle 19 is cleaned by the physiological saline by opening the valve 9, at this time, the first valve 5 and the second valve 4 are opened, the gas enters the air chamber 6 through the gas blowing port 2, the air chamber has a disinfection effect, the physiological saline is firstly stored in the storage chamber 10, the physiological saline with a proper volume is input, at this time, the physiological saline is blown to the top of the first drainage tube 16 by closing, but the process is that the volume of the inside of the tube is determined, at this time, the physiological saline with a certain volume (the volume smaller than the sum of the first drainage tube, the second drainage tube and the third drainage tube) is output, the liquid circulation of the drainage tubes above the first control valve 15 is not smooth, and the process is repeated for multiple times. When the blockage is below the first control valve 15, the first control valve 15 is directly closed, the first valve 5 is opened to extract the liquid in the blockage, so that the normal saline does not need to be treated, and the drainage tube above the first control valve 15 can be judged to have liquid circulation unsmooth after the extraction is finished or no liquid (the electronic flowmeter 12 or the material indication) passes through the blockage.

The physiological saline can avoid cell rupture in medicine, has the same osmotic pressure as that of the outside of the cells, so that the cells cannot be dehydrated or excessively absorb water, so that the physiological saline is used in various places needing liquid in medical operation, has the approximately same osmotic pressure value as that of the blood plasma and tissue fluid of a normal person, and can be used as a fluid replacement (without reducing or increasing the concentration of sodium ions in the body of the normal person). In addition, the storage bottle 19 can also collect other medicines which can have a disinfection function, the first control valve 15 can be closed firstly, the medicines in the storage bottle are utilized to disinfect the drainage tube, the drainage tube is kept clean and sterile when the drainage is not performed, the drainage bag is replaced every day, pollution is easily caused, the illness state of a patient is aggravated, and the prognosis is influenced. The first control valve 15 can also adjust the drainage speed, because the drainage tube is not easy to be found to be blocked or blocked, the intracranial pressure is easy to be increased, the upper and lower positions of the drainage bag need to be grasped, the low intracranial pressure syndrome is easy to be caused when the drainage bag is too low, and the drainage is not smooth when the drainage bag is too high, so the first control valve 15 is needed to complete the adjustment function.
It should be noted that, in the process of postoperative drainage of a patient, when the pressure inside the electronic flow meter 12 does not change much within a preset time, for example, within 10 seconds, the readings of the electronic flow meter 12 do not change, that is, the electronic flow meter 12 has no readings or a small readings, at this time, it can indicate that the drainage tube is blocked or the liquid is not smoothly circulated. After the device is triggered, the electronic flow meter 12 can be triggered again only when the valves are all restored to the original state, i.e., normal flow. The first flow sensor 11 and the second flow sensor 12 are used for communicating information to the server, such as whether liquid passes through the server or not, for a period of time. When the drainage is not smooth or the drainage is blocked, the liquid in the drainage tube is firstly pumped out, and then the drainage tube is flushed by using the normal saline, so that the drainage tube is kept smooth all the time, and the postoperative rehabilitation of a patient is facilitated. Therefore, the pressure of intracranial tissue fluid is obtained through the measuring instrument, drainage is carried out on a patient with obviously increased intracranial pressure, whether the drainage tube is blocked or not is determined by calculating the change rate of the reading of the flowmeter in the preset time through the server, and if the drainage tube is blocked, the drainage tube is flushed by utilizing the physiological saline through the triggering device, so that the whole device is more intelligent.

It should be noted that the pressure information of the tissue fluid of the patient is obtained by a measuring instrument (such as a sphygmomanometer), and the information is the pressure value of the tissue fluid at each time, and may be actually understood as an average pressure value within 1 second, for example. At this time, the server (computer program) records the change of the human tissue hydraulic pressure of the human tissue within the preset time, and can be understood as making a curve chart, and the curve chart can embody the pressure value and the pressure change condition. At this moment, the server judges whether the pressure value is greater than the preset pressure value, and the size between the numerical value is compared, and when the pressure value is greater than the preset pressure value, can think that the patient is in the drainage this moment, through judging whether the drainage tube blocks up, when the server has judged that the drainage tube blocks up, reachs diagnostic information this moment, and this diagnostic information can understand as the control signal who triggers drainage device, and back server transmits diagnostic information to terminal. This moment belongs to the in-process at patient postoperative drainage, when the drainage tube blockked up, at first, slowly extract remaining liquid in the drainage tube through extraction opening 2, and the inside liquid of drainage tube also has pressure this moment, when extracting liquid, slowly extracts, and it is many times to extract in the process, avoids suction too big, harms the human body for liquid is taken out from extraction opening 2. At this time, the inside of the drainage tube is in a liquid-free state, the second control valve 17 is closed, the physiological saline stored in the storage bottle 19 is cleaned by the physiological saline by opening the valve 9, at this time, the first valve 5 and the second valve 4 are opened, the gas enters the air chamber 6 through the gas blowing port 2, the air chamber has a disinfection effect, the physiological saline is firstly stored in the storage chamber 10, the physiological saline with a proper volume is input, at this time, the physiological saline is blown to the top of the first drainage tube 16 by closing, but the process is that the volume of the inside of the tube is determined, at this time, the physiological saline with a certain volume (the volume smaller than the sum of the first drainage tube, the second drainage tube and the third drainage tube) is output, the liquid circulation of the drainage tubes above the first control valve 15 is not smooth, and the process is repeated for multiple times. When the blockage is below the first control valve 15, the first control valve 15 is directly closed, the first valve 5 is opened to extract the liquid in the blockage, so that the normal saline does not need to be treated, and the drainage tube above the first control valve 15 can be judged to have liquid circulation unsmooth after the extraction is finished or no liquid (the electronic flowmeter 12 or the material indication) passes through the blockage. When not blocked, the first valve 5 is in a closed state, and the liquid cannot pass through the first valve 5, and the third valve 9 is also in a closed state. The liquid in the drainage tube is pumped out and the physiological saline is used for flushing the drainage tube, so that the drainage tube is kept smooth all the time, and the postoperative rehabilitation of a patient is facilitated.

s204, recording the flow information in the drainage tube within preset time;
s206, calculating a deviation value of the flow in the preset time according to the flow information in the drainage tube;
s208, judging whether the deviation value is not greater than a preset deviation threshold value;
s210, if not, obtaining diagnosis information;
it should be noted that the first flow sensor 11 and the second flow sensor 13 are used to obtain the flow information in the drainage tube, which is the flow value at each moment, and can be actually understood as the average value of the flow in 1 second, for example. The server records the flow information in the drainage tube within a preset time, so as to calculate a deviation value of the flow within the preset time according to the flow information in the drainage tube, wherein the deviation value is the flow of the liquid passing through the electronic flowmeter 12 within the preset time, for example, the flow passing through the electronic flowmeter is 100 ml within 10 seconds, and actually is the flow velocity of the flow. When the flow rate of the flow is not greater than the preset flow rate, too little liquid passes through the electronic flowmeter 12 within the preset time, and the drainage tube is blocked or not in a smooth state. The resulting information can actually be considered as a control signal that triggers the drainage device. When the drainage is not smooth or the drainage is blocked, the liquid in the drainage tube is firstly pumped out, and then the drainage tube is flushed by using the normal saline, so that the drainage tube is kept smooth all the time, and the postoperative rehabilitation of a patient is facilitated. However, when the trigger program is started, residual liquid in the drainage tube is slowly extracted through the extraction opening 2, and at the moment, the liquid in the drainage tube also has pressure intensity, and when the liquid is extracted, the liquid is slowly extracted, and the liquid is extracted for many times in the process, so that the phenomenon that the suction force is too large and the human body is injured is avoided, and the liquid is extracted from the extraction opening 2. At this time, the inside of the drainage tube is in a liquid-free state, the second control valve 17 is closed, the physiological saline stored in the storage bottle 19 is cleaned by the physiological saline by opening the valve 9, at this time, the first valve 5 and the second valve 4 are opened, the gas enters the gas chamber 6 through the gas blowing port 2, the gas chamber 6 has a sterilization effect, the physiological saline is stored in the storage chamber 10 at first, the physiological saline with a proper volume is input, at this time, the physiological saline is blown to the top of the first drainage tube 16 by closing, but the process is that the volume of the inside of the tube is determined, at this time, a certain volume (the volume smaller than the sum of the first drainage tube, the second drainage tube and the third drainage tube) of the physiological saline is output, the liquid flow of the drainage tube above the first control valve 15 is not smooth, and the process is repeated for multiple times. When the blockage is below the first control valve 15, the first control valve 15 is directly closed, the first valve 5 is opened to extract the liquid in the blockage, the normal saline treatment is not needed in the situation, and the drainage tube above the first control valve 15 is judged to have liquid circulation smoothly after the liquid is extracted or not (the electronic flow meter 12 or the index does not pass). In addition, the storage bottle 19 can also collect other medicines which can have a disinfection function, the first control valve 15 can be closed firstly, the medicines in the storage bottle are utilized to disinfect the drainage tube, the drainage tube is kept clean and sterile when the drainage is not performed, the drainage bag is replaced every day, pollution is easily caused, the illness state of a patient is aggravated, and the prognosis is influenced. The first control valve 15 can also adjust the drainage speed, the drainage tube is not easy to be found to be blocked or blocked, the intracranial pressure is easy to increase, the upper and lower positions of the drainage bag need to be grasped, the low intracranial pressure syndrome is easy to cause when the drainage bag is too low, the drainage is not smooth when the drainage bag is too high, and therefore the first control valve 15 is needed to complete the adjustment function.
The invention solves the defects in the background technology, and has the following beneficial effects:
when the drainage is not smooth or the drainage is blocked, the liquid in the tube is firstly pumped out by the air supply assembly, and then the drainage tube is flushed by the normal saline, so that the drainage tube is kept smooth all the time, the intracranial blood pressure of the patient is kept normal, and the postoperative rehabilitation of the patient is facilitated.
Obtain the pressure of intracranial tissue liquid through the measuring instrument, to the obvious patient that risees of intracranial pressure, carry out the drainage, whether the drainage tube is blockked up is confirmed at the rate of change of flowmeter reading in the preset time through the server calculation, if block up, through trigger device, utilizes normal saline to wash the drainage tube, makes whole device more intelligent.
In light of the foregoing description of the preferred embodiment of the present invention, it is to be understood that various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and the technology must be determined in accordance with the scope of the claims.
