Description
Technical Field
[0001] The utility model relates to the technical field related to infusion, and in particular to an accurate liquid level monitoring device for infusion. Background Art
[0002] Infusion refers to a large dose of injection introduced into the body by intravenous drip, with a single dose of more than 100 ml. It is a branch of injection and is usually packaged in glass or plastic infusion bottles or bags. It does not contain antibacterial agents. When used, the drip rate is adjusted through the infusion device to continuously and stably introduce the drug into the body. Therefore, a precise infusion liquid level monitoring device is particularly needed.
[0003] However, the existing precise infusion level monitoring devices cannot monitor in real time, are expensive, and have low accuracy, which cannot meet market demand. The market demand for precise infusion level monitors is still large, and there are many patients and few medical staff in hospitals. A nurse may need to serve multiple infusion patients at the same time. It is very stressful to be fully aware of the infusion status of each patient, deal with abnormal conditions in a timely manner, and provide patients with a high-quality medical experience. Utility Model Content
[0004] The purpose of the present utility model is to provide an infusion precise liquid level monitoring device to solve the problem that some infusion precise liquid level monitoring devices proposed in the above background technology cannot meet market demand due to the inability to monitor in real time, high price and low accuracy when in use. The market demand for infusion precise liquid level monitors is still very large, while there are many patients and few medical staff in hospitals. A nurse may need to serve multiple infusion patients at the same time. It is very stressful to be fully aware of the infusion situation of each patient, deal with abnormal conditions in time, and provide patients with a high-quality medical experience.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an infusion precise liquid level monitoring device, comprising a housing, a clamping clamp fixedly connected to the outer surface of the housing, a slide groove formed on the inner surface of the clamping clamp, a slider slidably connected to the inner surface of the slide groove, an infusion dripping hopper fixedly connected to the outer surface of the slider, a liquid inlet pipe fixedly connected to the upper surface of the infusion dripping hopper, a liquid outlet pipe fixedly connected to the lower surface of the infusion dripping hopper, a monitoring mechanism provided on the inner surface of the housing, and a rear shell snap-fitted to one side surface of the housing;
[0006] The monitoring mechanism includes a switch, a wire, an infrared light-emitting diode, an LM303-1 terminal, an LM303, an LM303-2 terminal, an LM303-3 terminal, a resistor, a receiving tube, an LED signal light and an alarm. The outer surface of the shell is fixedly connected to the switch, the outer surface of the switch is fixed to the wire, the outer surface of the wire is fixedly connected to the infrared light-emitting diode, the outer surface of the wire is fixedly connected to the LM303-1 terminal, one side surface of the LM303-1 terminal is fixedly connected to the LM303, one side surface of the LM303 is fixedly connected to the LM303-2 terminal, one side surface of the LM303 is fixedly connected to the LM303-3 terminal, the outer surface of the wire is fixedly connected to the resistor, the outer surface of the wire is fixedly connected to the receiving tube, the outer surface of the wire is fixedly connected to the LED signal light, and the outer surface of the wire is fixedly connected to the alarm.
[0007] Preferably, an LM303 is fixedly connected to the inner wall surface of the shell, and a resistor is fixedly connected to the inner wall surface of the shell.
[0008] Preferably, an LED signal light is fixedly connected to the outer wall surface of the shell, and an alarm is fixedly connected to the outer wall surface of the shell.
[0009] Preferably, an infrared light emitting diode is fixedly connected to the outer wall surface of the clamping clamp, and a receiving tube is fixedly connected to the outer wall surface of the clamping clamp.
[0010] Preferably, the inner wall surface of the clamping clamp is slidably connected to the infusion dripping hopper, and the size of the inner wall surface of the clamping clamp is consistent with the size of the outer wall surface of the infusion dripping hopper.
[0011] Preferably, the slide grooves are provided in two groups on the inner wall surface of the clamping clamp, and the sliding blocks are provided in two groups on the outer wall surface of the infusion dripping hopper.
[0012] Preferably, the infusion drip hopper forms a sliding structure through a slider and a slide groove, and the inner wall surface size of the slide groove is consistent with the outer wall surface size of the slider.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the device for accurately monitoring the liquid level of an infusion is provided with a monitoring mechanism. When in use, the infrared light emitting diode emits infrared light, and the receiving tube converts the received infrared light into electric current. When liquid drops fall from the infusion drop bucket, the infrared light is scattered due to the obstruction of the liquid drop, and the receiving tube cannot receive the infrared light emitted by the infrared light emitting diode, which is equivalent to the circuit being disconnected at the receiving tube, and the connection between the resistor and the receiving tube is equivalent to a wire. Under this condition, the level of the LM303-2 terminal of the LM393 is higher than the level of the LM303-3 terminal. At this time, the LM393 output port LM303-1 terminal will generate a low level. The LED signal light connected to the output port LM303-1 terminal has a high level VC in the forward direction. C, the reverse direction is a low level, so the LED signal light is turned on and lights up, indicating that there are drops passing through. When there are no drops in the infusion drop bucket, the infrared light can pass through due to the lack of drops blocking it. The receiving tube can sense the light emitted by the infrared light-emitting diode, forming a current path in the circuit. In this case, the receiving tube is in saturation conduction, the reverse LM303-2 end of LM393 is a low level, and the forward LM303-3 end is a high level. At this time, the LM393 output port LM303-1 end is a high level. Since the difference in voltage across the LED signal light is small, the LED signal light is not turned on and does not light up, indicating that no drops are passing through. This reduces the need for nurses to be fully aware of the infusion situation of each patient and the increased workload, thereby improving the work efficiency of medical staff.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-4 The utility model provides a technical solution: an infusion precise liquid level monitoring device, comprising a shell 1, a clamping clamp 2 is fixedly connected to the outer surface of the shell 1, a slide groove 3 is provided on the inner surface of the clamping clamp 2, a slider 4 is slidably connected to the inner surface of the slide groove 3, an infusion dropper 5 is fixedly connected to the outer surface of the slider 4, a liquid inlet pipe 6 is fixedly connected to the upper surface of the infusion dropper 5, a liquid outlet pipe 7 is fixedly connected to the lower surface of the infusion dropper 5, a monitoring mechanism 8 is provided on the inner surface of the shell 1, and a rear shell 9 is snap-connected to one side surface of the shell 1;
[0021] The monitoring mechanism 8 includes a switch 801, a wire 802, an infrared light emitting diode 803, an LM303-1 terminal 804, an LM303805, an LM303-2 terminal 806, an LM303-3 terminal 807, a resistor 808, a receiving tube 809, an LED signal light 810 and an alarm 811. The outer surface of the housing 1 is fixedly connected to the switch 801, the outer surface of the switch 801 is fixed to the wire 802, the outer surface of the wire 802 is fixedly connected to the infrared light emitting diode 803, the outer surface of the wire 802 is fixedly connected to the LM303-1 terminal 804, one side surface of the LM303-1 terminal 804 is fixedly connected to the LM303805, and one side surface of the LM303805 is fixedly connected to the LM 303-2 end 806, one side surface of LM303805 is fixedly connected with LM303-3 end 807, the outer surface of wire 802 is fixedly connected with resistor 808, the outer surface of wire 802 is fixedly connected with receiving tube 809, the outer surface of wire 802 is fixedly connected with LED signal light 810, the outer surface of wire 802 is fixedly connected with alarm 811, through the setting of switch 801, wire 802, infrared light emitting diode 803, LM303-1 end 804, LM303805, LM303-2 end 806, LM303-3 end 807, resistor 808, receiving tube 809, LED signal light 810 and alarm 811, when in use, infrared light emitting diode 803 emits infrared light, and the receiving tube 809 converts the received infrared light into current. When a drop of liquid falls into the infusion drop bucket 5, the infrared light is scattered due to the obstruction of the drop, and the receiving tube 809 cannot receive the infrared light emitted by the infrared light emitting diode 803. This is equivalent to the circuit being disconnected at the receiving tube 809, and the connection between the resistor 808 and the receiving tube 809 is equivalent to a wire 802. In this case, the level of the LM303-2 terminal 806 of the LM393805 is higher than the level of the LM303-3 terminal 807. At this time, the LM393805 output port LM303-1 terminal 804 will generate a low level. The LED signal light 810 connected to the output port LM303-1 terminal 804 has a high level V in the forward direction. CC, the reverse direction is a low level, so the LED signal light 810 is turned on and illuminated, indicating that a droplet has passed. When no droplet falls in the infusion drop bucket 5, the infrared light can pass through due to the absence of a droplet obstruction. The receiving tube 809 can sense the light emitted from the infrared light-emitting diode 803, forming a current path in the circuit. In this case, the receiving tube 809 is in saturation conduction, the reverse LM303-2 terminal 806 of the LM393805 is a low level, and the forward LM303-3 terminal 807 is a high level. At this time, the output port LM303-1 terminal 804 of the LM393805 is a high level. Since the difference in voltage between the two ends of the LED signal light 810 is small, the LED signal light 810 is not turned on and does not illuminate, indicating that no droplet has passed.
[0022] Furthermore, an LM303805 is fixedly connected to the inner wall surface of the shell 1, and a resistor 808 is fixedly connected to the inner wall surface of the shell 1. Through the setting of the LM303805 and the resistor 808, when in use, when the level of the LM303-2 terminal 806 of the LM393805 is higher than the level of the LM303-3 terminal 807, the LED signal light 810 is turned on and illuminated, indicating that a droplet has passed through; when the level of the LM303-2 terminal 806 of the LM393805 is lower than the level of the LM303-3 terminal 807, the LED signal light 810 does not illuminate, indicating that no droplet has passed through.
[0023] Furthermore, an LED signal light 810 is fixedly connected to the outer wall surface of the shell 1, and an alarm 811 is fixedly connected to the outer wall surface of the shell 1. Through the setting of the LED signal light 810 and the alarm 811, when in use, when the LED signal light 810 is turned on and illuminated, it indicates that there are droplets passing through, and when the LED signal light 810 is not illuminated, it indicates that there are no droplets passing through, making it more convenient to understand whether there are droplets in the infusion drop bucket 5.
[0024] Furthermore, an infrared light emitting diode 803 is fixedly connected to the outer wall surface of the clamping clamp 2, and a receiving tube 809 is fixedly connected to the outer wall surface of the clamping clamp 2. Through the setting of the infrared light emitting diode 803 and the receiving tube 809, when in use, the infrared light emitting diode 803 emits infrared light, and the receiving tube 809 converts the received infrared light into electric current. When liquid drops fall from the infusion droplet 5, the infrared light is scattered due to the obstruction of the liquid droplet, and the receiving tube 809 cannot receive the infrared light emitted by the infrared light emitting diode 803, thereby causing the LED signal light 810 to light up. When no liquid drops fall from the infusion droplet 5, the receiving tube 809 receives the infrared light emitted by the infrared light emitting diode 803, thereby causing the LED signal light 810 to not light up.
[0025] Furthermore, the inner wall surface of the clamping clamp 2 is slidingly connected to the infusion drip bucket 5, and the size of the inner wall surface of the clamping clamp 2 is consistent with the size of the outer wall surface of the infusion drip bucket 5. Through the setting of the clamping clamp 2, when in use, the infusion drip bucket 5 is stably placed on the clamping clamp 2, so that the infrared light emitted by the infrared light emitting diode 803 can pass through the infusion drip bucket 5.
[0026] Furthermore, two groups of slide grooves 3 are provided on the inner wall surface of the clamping clamp 2, and two groups of sliders 4 are provided on the outer wall surface of the infusion drip bucket 5. Through the setting of the slide grooves 3, when in use, the slide grooves 3 enable the infusion drip bucket 5 to fit firmly on the inner wall surface of the clamping clamp 2.
[0027] Furthermore, the infusion drip hopper 5 forms a sliding structure with the slide trough 3 through the slider 4, and the inner wall surface size of the slide trough 3 is consistent with the outer wall surface size of the slider 4. Through the setting of the slider 4, when in use, the slider 4 enables the infusion drip hopper 5 to fit with the clamping clamp 2, thereby ensuring that the infrared light emitted by the infrared light emitting diode 803 can pass through the infusion drip hopper 5.
[0028] Working principle: The infusion dropper 5 is engaged with the chute 3 through the slider 4, so that it is stably placed on the clamping clamp 2. The infrared light emitting diode 803 emits infrared light, and the receiving tube 809 converts the received infrared light into current. When a drop of liquid falls from the infusion dropper 5, the infrared light is scattered due to the obstruction of the drop, and the receiving tube 809 cannot receive the infrared light emitted by the infrared light emitting diode 803, which is equivalent to the circuit being disconnected at the receiving tube 809, and the connection between the resistor 808 and the receiving tube 809 is equivalent to a wire. 802. In this situation, the level of LM303-2 terminal 806 of LM393805 is higher than the level of LM303-3 terminal 807. At this time, the output port LM303-1 terminal 804 of LM393805 will produce a low level. The LED signal light 810 connected to the output port LM303-1 terminal 804 has a high level VCC in the forward direction and a low level in the reverse direction. Therefore, the LED signal light 810 is turned on and lights up, indicating that there is a droplet passing through. When there is no droplet falling from the infusion dropper 5, Since there is no obstruction of liquid droplets, infrared light can pass through, and the receiving tube 809 can sense the light emitted by the infrared light-emitting diode 803, forming a current path in the circuit. In this case, the receiving tube 809 is in saturation conduction, the inverting LM303-2 terminal 806 of the LM393805 is at a low level, and the positive phase LM303-3 terminal 807 is at a high level. At this time, the output port LM303-1 terminal 804 of the LM393805 is at a high level. Since the voltage difference between the two ends of the LED signal light 810 is small, the LED signal light 810 is not turned on and does not emit light, indicating that no liquid droplets have passed. This solves the problem of being unable to monitor in real time, being expensive, and having low accuracy, which cannot meet market demand. The market demand for accurate infusion level monitors is still large, but there are many patients and few medical staff in hospitals. A nurse may need to serve multiple infusion patients at the same time. It is very stressful to be fully aware of the infusion situation of each patient, deal with abnormal conditions in a timely manner, and provide patients with a high-quality medical experience.
[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
