Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a fluid discharge device and a discharge method for tumor care. Background Art

[0002] In tumor nursing, fluid discharge is an important nursing task. Tumors can cause peritoneal or pleural effusion. Under pathological conditions, when the amount of fluid in the peritoneal or pleural cavity exceeds 200 ml, it is called effusion. When a large amount of effusion affects the patient's breathing or the abdominal distension symptoms are severe and unbearable, the fluid in the cavity needs to be discharged. The general discharge method is to use a syringe connected to a puncture needle for extraction or connect to a drainage bag for drainage, or use an air pump to discharge the effusion.

[0003] In tumor care, when draining the intracavitary fluid, medical staff need to pay attention to the patient's condition at all times. They may not be able to flexibly and effectively control the rate and amount of fluid discharge, which may cause the fluid to be discharged too quickly or too much and cause discomfort to the patient. During the fluid discharge process, the patient's pain may increase or greater medical risks may occur. For this reason, we propose a fluid discharge device and discharge method for tumor care.

[0016] The discharge method of the fluid discharge device for tumor care: Step 1: The medical staff controls the motor to work through the controller to move the moving block upward or downward to adjust the discharge amount of the fluid accumulation as needed, press the switch 1 and move the dial block upward or downward to adjust the sliding position of the sliding rheostat, and then adjust the opening and closing degree of the solenoid valve 1 to a suitable position to adjust the discharge rate of the fluid accumulation according to the patient's condition;

[0017] Step 2: Negative pressure can be formed in the fluid accumulation barrel through the air pump, so that the accumulated fluid in the patient's cavity is discharged into the fluid accumulation barrel through the puncture needle, drainage tube, three-way pipe and liquid inlet pipe. During the discharge of the accumulated fluid, the controller will control the solenoid valve 2 to open and the solenoid valve 3 to close, and the accumulated fluid will enter the barrel through the three-way pipe. Within the set time, if the discharge rate of the accumulated fluid is faster, more accumulated fluid will enter the barrel, so that the floating ball 1 floats up a larger distance, which will press the pressure plate to move up, and then the connecting block can be moved down, and the resistance value of the sliding rheostat connected to the circuit is increased, so that the opening and closing degree of the solenoid valve 1 is reduced, so that the negative pressure in the fluid accumulation barrel is reduced, thereby reducing the discharge rate of the accumulated fluid, and preventing the rapid discharge of the accumulated fluid from causing discomfort to the patient;

[0018] Step three: When the discharge amount of the accumulated liquid is about to reach the set total amount, the accumulated liquid in the liquid accumulation barrel will first cause the float ball 2 to float up, causing the gear rod 3 to move up, and then the connecting block can be moved down, so that the resistance value of the sliding rheostat connected to the circuit increases, and the discharge rate of the accumulated liquid is reduced. When the discharge amount of the accumulated liquid reaches the set total amount, the continued upward movement of the float ball 2 will cause the connecting shell 2 away from the connecting block to press against the switch 2, so that the air pump is closed to stop the discharge of the accumulated liquid. Therefore, when the discharge of the accumulated liquid is about to reach the set total amount, the discharge rate of the accumulated liquid can be gradually reduced until the discharge of the accumulated liquid is finally stopped, which can reduce the patient's discomfort.

[0019] The present invention has at least the following beneficial effects:

[0020] The present invention can discharge the accumulated fluid in the patient's cavity through the adjustment component, and can adjust the discharge rate of the accumulated fluid according to the conditions of different patients, and in the process of discharging the accumulated fluid, the discharge rate of the accumulated fluid can be adjusted automatically to prevent the rapid discharge rate of the accumulated fluid from causing discomfort to the patient, increasing the patient's pain or causing greater medical risks. The discharge amount of the accumulated fluid can be adjusted and limited through the limiting component to prevent excessive discharge of the accumulated fluid from causing discomfort to the patient, and when the discharge amount of the accumulated fluid is about to reach the set total amount of the accumulated fluid, the discharge rate of the accumulated fluid can be gradually reduced until the discharge of the accumulated fluid is finally stopped, thereby further reducing the patient's discomfort during the discharge of the accumulated fluid.

[0043] A connecting shell 225 is fixedly arranged on one side of the limiting member 221, and a tooth block 227 adapted to the tooth rod 217 and the second tooth rod 222 is slidably arranged in the connecting shell 225. The tooth block 227 movably penetrates one side of the limiting member 221 so that the tooth block 227 can be engaged with the tooth groove of the tooth rod 217 or the second tooth rod 222.

[0044] Press switch 1 215 and move the dial block 214 upward or downward. By pressing switch 1 215, the electromagnetic blocks 1 226 and the electromagnetic blocks 2 229 on both sides can be energized, so that the electromagnetic block 1 226 can adsorb the tooth block 1 227, so that the tooth block 1 227 moves close to the electromagnetic block 1 226 and breaks away from the tooth groove of the tooth bar 1 217 or the tooth bar 222. The spring 1 228 is stretched so that when the connecting block 210 moves upward or downward, it will not drive the movement of the limiter 1 221; by moving the dial block 214 upward or downward, the connecting rod 213 and the connecting block 210 drive the slider of the sliding rheostat 29 to move upward or downward, so as to adjust the resistance of the sliding rheostat 29 connected to the circuit and change the current in the circuit. , and then adjust the opening and closing degree of the electromagnetic valve 25 to a suitable position to adjust the discharge rate of the effusion according to the patient's condition; press the switch 215 to energize the electromagnetic block 229, so that the limit piece 221 on the side away from the connecting block 210 can be adsorbed by the electromagnetic block 229 and the adsorption block 230. When the moving block 214 drives the connecting block 210, the support 216 and the gear rod 217 to move, the position of the rotating plate 219 is maintained so that the rotating plate 219 does not rotate. After the adjustment is completed, release the block 214 and the switch 215, and under the elastic force of the spring 228, the gear block 227 moves away from the electromagnetic block 226 and engages with the gear rod 217 or the gear rod 222.

[0045] A cylinder 234 fixed to the mounting plate 22 is fixedly disposed at the other end of the three-way pipe 26, a float 235 is disposed in the cylinder 234, a pressure rod 28 movably penetrating the top of the cylinder 234 is fixedly disposed on the upper side of the float 235, a pressure plate 233 fixed to the upper end of the second gear rod 222 is disposed on the upper side of the pressure rod 28, a liquid outlet pipe 224 penetrating the mounting plate 22 is fixedly disposed on the lower side of the cylinder 234, the liquid outlet pipe 224 is communicated with the cylinder 234 and the liquid accumulation bucket 11, a solenoid valve 3 231 is installed on the liquid outlet pipe 224, a solenoid valve 220 is installed on the three-way pipe 26, the solenoid valve 220 is located on a branch pipe on one side of the three-way pipe 26 connected to the cylinder 234, and an L-shaped rod 232 abutting against the upper side of the connecting rod 213 is fixedly disposed on one side of the gear rod 222;

[0046] Initially, the solenoid valve three 231 is in an open state. When the air pump 23 extracts the gas in the liquid accumulation barrel 11, the gas in the cylinder 234 can also be extracted. During the discharge of the accumulated liquid, the controller 212 controls the solenoid valve three 231 to close and the solenoid valve two 220 to open, so that the accumulated liquid can enter the cylinder 234 through the three-way pipe 26. When the set time is reached, the solenoid valve three 231 is controlled to open and the solenoid valve two 220 is controlled to close, so that the accumulated liquid in the cylinder 234 is discharged into the liquid accumulation barrel 11 through the liquid outlet pipe 224. The opening and closing of the solenoid valve three 231 and the solenoid valve two 220 are repeatedly controlled in this way. Therefore, within the set time, if the discharge rate of the accumulated liquid is faster, more accumulated liquid will enter the cylinder 234, so that the float one 235 drives the pressure rod 28 to move up a larger distance;

[0047] When the switch 1 215 is pressed and the shift block 214 is moved upward, the upward movement of the connecting rod 213 will drive the L-shaped rod 232 to move upward, so that the gear rod 222 and the pressure plate 233 move upward, so that the initial spacing between the pressure plate 233 and the pressure rod 28 increases to adapt to the increase in the discharge rate of the adjusted accumulated liquid. Conversely, the shift block 214 drives the connecting rod 213 to move downward, and the gear rod 222, the pressure plate 233 and the L-shaped rod 232 move downward accordingly under the action of gravity. The pressure plate 233 can also be manually pressed downward as the shift block 214 moves downward, so that the spacing between the pressure plate 233 and the pressure rod 28 decreases to adapt to the decrease in the discharge rate of the adjusted accumulated liquid. Therefore, during the discharge of the accumulated liquid, if the discharge rate of the accumulated liquid is faster, more accumulated liquid will enter the cylinder 234 within the set time, so that The distance that the float 235 and the pressure rod 28 move upward is larger than the adjusted distance, so that the pressure rod 28 will push the pressure plate 233 upward, so that the gear rod 222 and the limit piece 221 on the side away from the connecting block 210 move upward, and through the rotation of the rotating plate 219, the limit piece 221 on the side close to the connecting block 210 drives the gear rod 217 to move downward, thereby causing the support 216 and the connecting block 210 to move downward, and causing the sliding piece of the sliding rheostat 29 to move downward, so that the resistance value of the circuit connected to the upper side of the sliding rheostat 29 increases, the current in the circuit decreases, and the opening and closing degree of the solenoid valve 25 decreases, so that the gas extracted by the air pump 23 is reduced, and the negative pressure in the liquid accumulation barrel 11 is smaller, thereby reducing the discharge rate of the accumulated liquid, and preventing the accumulated liquid from being discharged too quickly and causing discomfort to the patient.

An adsorption plate 322 is fixedly provided on the lower side of the second limiting member 313, and an electromagnetic block 319 fixed to the mounting plate 22 is provided on the lower side of the adsorption plate 322. A switch 321 is installed on the lower side of the second connecting shell 315 of the mounting plate 22 which is located away from the connecting block 210. The switch 321 is electrically connected to the electromagnetic block 316 and the electromagnetic block 1 226 on the side close to the connecting block 210. An L-shaped plate 320 fixed to the mounting plate 22 is provided on one side of the switch 321, and a switch 2 314 electrically connected to the air pump 23 is installed on the lower side of the L-shaped plate 320;

[0052] When the control motor 31 is working and the position of the moving block 33 is adjusted, the electromagnetic block 316 and the electromagnetic block 319 on the side away from the connecting block 210 can be energized at the same time, so that the tooth block 317 moves close to the electromagnetic block 316 and disengages from the tooth groove of the gear rod 35, and the spring 218 is stretched so that the tooth block 317 will not hinder the gear rod 35 from moving up and down with the moving block 33. Through the adsorption effect of the electromagnetic block 419 on the adsorption plate 322, the positions of the limiter 2313 and the rotating plate 2312 can be maintained when the gear rod 35 moves up and down. After the position adjustment of the moving block 33 is completed, the control motor 31 is turned off, and the electromagnetic block 316 and the electromagnetic block 4319 on the side away from the connecting block 210 are de-energized. Under the elastic force of the spring 218, the tooth block 2317 is engaged with the gear rod 35, and the adsorption effect between the electromagnetic block 4319 and the adsorption plate 322 is released.

[0053] Initially, the electromagnetic block three 316 near the side of the connecting block 210 is energized, so that the tooth block two 317 near the side of the connecting block 210 is not engaged with the gear rod four 310, so as not to affect the adjustment of the sliding position of the sliding rheostat 29 by the adjusting component 2. When the discharge amount of the accumulated liquid is about to reach the set total amount, the accumulated liquid in the liquid accumulation barrel 11 will first float the float ball two 36, so that the gear rod three 35 moves up, so that the limit piece two 313 away from the side of the connecting block 210 moves up, so that the limit piece two 313 no longer presses the switch three 321, so that the electromagnetic block three 316 near the side of the connecting block 210 is de-energized, so that the gear block two 317 is engaged with the gear rod four 310, and the electromagnetic block one 226 near the side of the connecting block 210 is energized, so that the gear block one 227 is separated from the gear rod one 217, so that the rotating plate two 312 can rotate. , so that the limit piece 2 313 on the side close to the connecting block 210 drives the gear rod 4 310 to move downward, so that the pillar 2 39 and the connecting block 210 move downward, so that the sliding piece of the sliding rheostat 29 moves downward, so that the resistance value of the sliding rheostat 29 connected to the circuit increases, so that the opening and closing degree of the solenoid valve 1 25 decreases, and the discharge rate of the accumulated liquid is reduced. After the float 2 36 floats to the bottom side of the moving block 33, the connecting shell 2 315 on the side away from the connecting block 210 will press the switch 2 314, so that the air pump 23 stops working to stop the discharge of the accumulated liquid, thereby limiting the discharge amount of the accumulated liquid to prevent excessive discharge of the accumulated liquid from causing discomfort to the patient, and when the discharge amount of the accumulated liquid is about to reach the set total amount of the accumulated liquid, the discharge rate of the accumulated liquid can be gradually reduced until the discharge of the accumulated liquid is finally stopped, thereby further alleviating the patient's discomfort.

[0054] Discharge method of the fluid discharge device for tumor care: Step 1: The medical staff controls the motor 31 to work through the controller 212, so that the moving block 33 moves upward or downward to adjust the discharge amount of the fluid accumulation as needed, presses the switch 1 215 and moves the dial block 214 upward or downward to adjust the sliding position of the sliding rheostat 29, and then adjusts the opening and closing degree of the solenoid valve 1 25 to a suitable position to adjust the discharge rate of the fluid accumulation according to the patient's condition;

[0055] Step 2: Negative pressure can be formed in the fluid accumulation barrel 11 through the air pump 23, so that the accumulated fluid in the patient's cavity is discharged into the fluid accumulation barrel 11 through the puncture needle 13, the drainage tube 12, the three-way pipe 26 and the liquid inlet pipe 27. During the discharge of the accumulated fluid, the controller 212 will control the solenoid valve 220 to open and the solenoid valve 3 231 to close, and the accumulated fluid will enter the cylinder 234 through the three-way pipe 26. Within the set time, if the discharge rate of the accumulated fluid is faster, more accumulated fluid will enter the cylinder 234, so that the floating ball 1 235 floats a larger distance, which will press the pressure plate 233 to move upward, and then the connecting block 210 can be moved downward, and the resistance value of the sliding rheostat 29 connected to the circuit is increased, so that the opening and closing degree of the solenoid valve 1 25 is reduced, so that the negative pressure in the fluid accumulation barrel 11 is reduced, thereby reducing the discharge rate of the accumulated fluid and preventing the rapid discharge of the accumulated fluid from causing discomfort to the patient;

[0056] Step three: When the discharge amount of the accumulated fluid is about to reach the set total amount, the accumulated fluid in the fluid accumulation barrel 11 will first cause the float 2 36 to float up, causing the gear rod 35 to move up, and then the connecting block 210 to move down, thereby increasing the resistance of the sliding rheostat 29 connected to the circuit, and reducing the discharge rate of the accumulated fluid. When the discharge amount of the accumulated fluid reaches the set total amount, the continued upward movement of the float 2 36 will cause the connecting shell 2 315 away from the side of the connecting block 210 to press against the switch 2 314, so that the air pump 23 is turned off to stop the discharge of the accumulated fluid. Therefore, when the discharge of the accumulated fluid is about to reach the set total amount, the discharge rate of the accumulated fluid can be gradually reduced until the discharge of the accumulated fluid is finally stopped, thereby alleviating the patient's discomfort.

10. A method for discharging fluid using the effusion discharging device for tumor care according to claim 9, characterized in that: Step 1: The medical staff controls the motor (31) through the controller (212) to move the moving block (33) upward or downward to adjust the discharge amount of the accumulated fluid as needed, presses the switch (215) and moves the dial block (214) upward or downward to adjust the sliding position of the sliding rheostat (29), and then adjusts the opening and closing degree of the solenoid valve (25) to a suitable position to adjust the discharge rate of the accumulated fluid according to the patient's condition; Step 2: A negative pressure is formed in the fluid accumulation barrel (11) through the air pump (23), so that the accumulated fluid in the patient's cavity is discharged into the fluid accumulation barrel (11) through the puncture needle (13), the drainage tube (12), the three-way pipe (26) and the liquid inlet pipe (27). During the discharge of the accumulated fluid, the controller (212) controls the electromagnetic valve 2 (220) to open and the electromagnetic valve 3 (231) to close, and the accumulated fluid enters the cylinder (234) through the three-way pipe (26). Within the set time, If the discharge rate of the accumulated liquid is fast, more accumulated liquid will enter the cylinder (234), causing the float ball (235) to float up a larger distance, which will press the pressure plate (233) to move upward, thereby causing the connection block (210) to move downward, and adjusting the resistance value of the sliding rheostat (29) connected to the circuit to increase, so that the opening and closing degree of the solenoid valve (25) is reduced, so that the negative pressure in the liquid accumulation barrel (11) is reduced, thereby reducing the discharge rate of the accumulated liquid, and preventing the accumulated liquid from being discharged too quickly and causing discomfort to the patient; Step 3: When the discharge amount of the accumulated liquid is about to reach the set total amount, the accumulated liquid in the liquid accumulation barrel (11) will first cause the float 2 (36) to float up, causing the gear rod 3 (35) to move up, and then the connecting block (210) to move down, increasing the resistance value of the sliding rheostat (29) connected to the circuit, thereby reducing the discharge rate of the accumulated liquid. When the discharge amount of the accumulated liquid reaches the set total amount, the continued upward movement of the float 2 (36) will cause the connecting shell 2 (315) on the side away from the connecting block (210) to press against the switch 2 (314), causing the air pump (23) to close to stop the discharge of the accumulated liquid. Therefore, when the discharge of the accumulated liquid is about to reach the set total amount, the discharge rate of the accumulated liquid can be gradually reduced until the discharge of the accumulated liquid is finally stopped, thereby alleviating the patient's discomfort.
