Brief Description of The Figures Fig. 1 is a schematic diagram of the use structure of a wall-embedded infusion remote control alarm mechanism; Fig. 2 is a structural schematic diagram of the first embodiment of a wall-embedded infusion remote control alarm mechanism; Fig. 3 is a structural schematic diagram of the second embodiment of a wall-embedded infusion remote control alarm mechanism.
Description of the present invention Embodiment 1 Referring to Fig. 1 and Fig. 2. Fig. 1 is a schematic diagram of the use structure, which includes a catheter and a wall-embedded infusion remote-control alarm mechanism.
The two ends of the sleeve 1 of the wall-embedded infusion remote control alarm mechanism of the present invention are connected to the catheter. When the sleeve 1 is filled with liquid, the floating ball 22 floats up, and the two electrode contacts (the first electrode contact 24 and the second electrode contact 25) are out of contact, so that the 294 alarm does not set off. When there is no liquid in the sleeve 1, the floating ball 22 falls, and the two electrode contacts (the first electrode contact 24 and the second electrode contact 25) come into contact, and the mechanism sends out a liquid-running out alarm.
The invention relates to embedded wall type transfusion remote control liquid running out alarm mechanism, which mainly comprises sleeve 1, floating ball compartment 2 and alarm circuit 3, wherein the sleeve 1 can be connected with catheter, and the floating ball compartment 2 embedded in the wall of the sleeve 1 can send out a liquid-cut alarm together with the alarm circuit 3, and transmit the signal to a centralized control terminal 4 by wireless communication.
Referring to Fig. 2, which is a schematic diagram of the structure of the embedded wall type transfusion remote control liquid running out alarm mechanism. The mechanism includes sleeve 1, floating ball compartment 2 and alarm circuit 3. Both ends of the sleeve 1 can be connected with a catheter, and the floating ball 22 in the floating ball compartment 2 falls when the liquid interruption occurs, causing two electrode contacts (the first electrode contact 24 and the second electrode contact 25) to contact, and the alarm circuit sends out a liquid interruption alarm.
The liquid cut-off alarm mechanism consists of sleeve 1, floating ball compartment 2 and alarm circuit 3. The sleeve 1 and the floating ball compartment 2 of the alarm mechanism are made of nontoxic transparent plastic. The floating ball compartment 2 communicates with the liquid cavity 12 of the sleeve 1, and the width of the communicating window is smaller than the diameter of the floating ball 22, so that the floating ball 22 is confined in the compartment.
Because of the intercommunication, once there is liquid in the sleeve 1, there will also be liquid in the floating ball compartment 2. The floating ball 22 is a hollow body, and the liquid in the floating ball compartment 2 will make the floating ball 22 float upwards. Because the bottom of the floating ball 22 is connected with the flexible waterproof film 23 as a whole, When the floating ball 22 floats upwards, it pulls up the flexible waterproof film 23, which causes the second electrode contact 25 located at the bottom of the flexible waterproof film 23 to be out of contact with the first electrode contact 24 located at tha 22% bottom of the cabin. At this point, due to the action of the pull-up resistor 35, the input of the alarm circuit is in a high-level state, and no alarm is generated. Because the flexible waterproof film 23 is very light and soft, it will be pulled up whenever the floating ball 22 floats up. Therefore, as long as there is liquid in the sleeve 1, the flexible waterproof film 23 will be pulled up all the time, and the two electrode contacts (the first electrode contact 24 and the second electrode contact 25) will be out of contact all the time, and the liquid-off alarm circuit does not set off an alarm.
When there is no liquid in the sleeve 1, the liquid in the floating ball compartment 2 will completely flow along the bottom of the tank with an inclined slope, the floating ball 22 will fall to the bottom, the flexible waterproof film 23 will fall to the bottom, and the umbrella-shaped electrode contact (second electrode contact 25) of the upper flexible waterproof film 23 will be in close contact with the hemispherical electrode contact (first electrode contact 24) of the lower tank bottom. The contact state is transmitted to the alarm circuit 3 through the metal lead wire insulated by the outer skin. At this time, the MCU36 input of the alarm circuit 3 is at a low level, which causes the external interrupt response of the MCUS36, starts the acousto-optic alarm circuit, sends out the flash and sound of the liquid cut-off alarm, and at the same time sends an alarm signal to the centralized control terminal 4 through the wireless communication circuit 37, thus achieving the purpose of liquid running out alarm.
The waterproof film 23 is hermetically combined with the bottom of the compartment 21, and there is a liquid-free space. In order to make the flexible waterproof film 23 easy to pull up and fall down, the bottom of the cabin body 21 has tiny holes communicating with the outside for air suction and exhaust in the closed space, and at the same point, the tiny holes are also used to lead the lead wires of the connecting electrodes out of the pipe from the closed space and connect to the alarm circuit. The centralized control terminal 4 can be located in the nurse station of the hospital or in the control room of drip irrigation, which is the terminal for centralized management and control.
In this embodiment, the MCU36 and the wireless communication circuit 37 can be chips commonly used in the electronic field, so they will not be described again.
The liquid-contacting component of the invention is made of nontoxic medical olastie 1294 which is nontoxic, harmless and sterile, and the interior is easy to clean and disinfect, so it can be used in infusion places with high sanitary requirements.
Embodiment 2 Referring to Fig. 3, the main difference between this embodiment and the first embodiment is that the alarm circuit is more simplified, only audible and visual alarm occurs, and the alarm information is not transmitted to the centralized control terminal 4. The alarm circuit 3 consists of power supply 32, start switch 31, LED 33 and buzzer 34. The LED33 and the buzzer 34 are connected in parallel to form an alarm branch. The alarm branch, the start switch 31, the first electrode contact 24, the second electrode contact 25 and the power supply 32 are connected in series in turn.
The start switch 31 is a self-locking switch, which is always on after being pressed, and will only be turned off after being pressed again, and can be turned off when there is no need for liquid shortage alarm. Because the flexible waterproof film 23 is very light and soft, it will be pulled up whenever the floating ball 22 floats up. Therefore, as long as there is water in the sleeve 1, the flexible waterproof film 23 will be pulled up all the time, and the two electrode contacts (the first electrode contact 24 and the second electrode contact 25) are always out of contact, and the water shortage alarm circuit 3 never works.
When the water in the sleeve 1 is cut off, the water in the compartment 2 of the floating ball 22 will completely flow along the bottom of the inclined slope, the floating ball 22 will fall to the bottom, the flexible waterproof film 23 will fall to the bottom, and the two electrode contacts will be in close contact, and the alarm circuit 3 will be connected through the metal lead wire insulated by the outer skin, the LED will light up, the buzzer will sound, and the water shortage alarm will be issued, so as to achieve the purpose of water shortage alarm.
The above examples illustrate the present invention, not limit it. Any simple transformation scheme of the present invention belongs to the scope of protection of the present invention.
