[0001] The present invention relates to the technical field of infusion pumps, and more particularly to an intelligent monitoring infusion pump. Background Art

[0002] Infusion pumps are typically mechanical or electronic control devices that act on infusion catheters to control the rate of infusion. They are often used in situations where strict control of infusion volume and medication dosage is required, such as when administering pressor drugs, antiarrhythmic drugs, intravenous infusions, or intravenous anesthesia.

[0003] Among them, the patent with announcement number CN220046699U discloses an infusion pump, which includes a main body and a driving device, wherein the driving device includes a driving part, a cam mechanism and an extrusion mechanism, the cam mechanism includes a connecting shaft, and a first cam, a second cam and a third cam provided on the connecting shaft, along the axial direction of the connecting shaft, the first cam and the third cam are respectively provided on both sides of the second cam, the extrusion mechanism includes a first extrusion part, a second extrusion part and a third extrusion part, the first extrusion part can squeeze the first infusion tube under the drive of the first cam, the second extrusion part can squeeze the liquid medicine in the extrusion chamber under the drive of the second cam, so that the liquid medicine enters the second infusion tube, and the third extrusion part can squeeze the second infusion tube under the drive of the third cam; When this structure is in use, the detection surface of the pressure sensor can press against the second infusion tube, thereby detecting the hydraulic pressure in the second infusion tube, which helps to detect whether there are bubbles in the second infusion tube. When there are bubbles in the second infusion tube, the pressure sensor will issue an alarm. However, this structure only realizes the functions of detecting pressure and prompting an alarm, and cannot realize the function of quickly adjusting the pressure and then adjusting the flow rate of the liquid medicine. It is also not easy to eliminate bubbles in the liquid medicine, and is not convenient enough when used. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intelligent monitoring infusion pump, which aims to solve the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solutions: an intelligent monitoring infusion pump, comprising a connecting tube, on which a diversion monitoring component is provided; The diversion monitoring assembly includes a gathering ring embedded in the connecting tube, a center block is provided in the middle of the gathering ring, a baffle is provided at the bottom of the center block, and a storage cavity is formed between the center block and the baffle; A liquid level monitoring sensor is provided on one side of the surface of the connecting cylinder, a mounting cylinder is provided on the other side of the connecting cylinder, and the mounting cylinder is communicated with the connecting cylinder, and an air inlet cylinder is provided on the outside of the mounting cylinder; A plurality of mounting grooves are provided on the outer side of the central block, and a diverter plate is embedded in each of the mounting grooves. A diverter cavity is formed between the central block and the gathering ring.

[0006] Optionally, in a possible embodiment, a piston is slidably connected in the mounting cylinder, a first spring is provided at one end of the piston, a knob is provided at the end of the first spring away from the piston, a knob is provided at the end of the first spring away from the piston, an electric push rod is provided at the end of the mounting cylinder away from the knob, the knob is threadedly connected to the mounting cylinder, and an output end of the electric push rod passes through the mounting cylinder and extends to one end of the piston; Optionally, in one possible embodiment, a groove is provided on one side of the surface of the gathering ring, an electric heating block is provided on the inner wall of the connecting tube, the electric heating block extends into the groove, a plurality of liquid outlets are provided through the baffle, and a support ring is provided on the bottom of the baffle; Optionally, in a possible embodiment, a support ring is provided at the bottom of the baffle, a second spring is provided at the bottom of the support ring, a vertical cylinder is provided at the bottom of the second spring, the top of the second spring is in contact with the support ring, a joint is provided at the bottom of the vertical cylinder, the vertical cylinder and the joint are both located at the bottom of the connecting cylinder, a puncture head is provided at the top of the connecting cylinder, a limiting cover is provided on the outer side of the puncture head, and the limiting cover is placed horizontally at the top of the connecting cylinder and is clamped with the connecting cylinder.

[0007] The technical effects and advantages of the present invention are as follows: 1. The present invention flexibly adjusts the air intake volume to control the air pressure within the connecting tube through the coordinated action of the piston in the installation tube, the first spring, the knob, and the electric push rod. Manually rotating the knob presets the elastic range of the first spring, and the piston slides together to precisely adjust the opening size at the connection between the installation tube and the air intake tube, enabling manual fine-tuning of the liquid flow rate. The electric push rod drives the piston to rapidly move, quickly sealing the air path in the event of an abnormal liquid level or when emergency liquid shutdown is required, achieving automated emergency regulation of pressure and flow. This solves the problem of existing technologies that can only detect pressure but cannot quickly adjust it.

[0008] 2. The diversion plate on the outside of the central block of the present invention and the diversion cavity formed by the gathering ring constitute a multi-stage diversion structure. After being guided by the diversion plate, the medicinal liquid flows smoothly in the diversion cavity, reducing bubbles generated by turbulence; at the same time, the storage cavity formed by the central block and the baffle can temporarily store the medicinal liquid, allowing bubbles to rise and escape under the action of buoyancy, preventing bubbles from entering the patient's blood vessels with the medicinal liquid, thereby solving the defect of the existing technology that it is difficult to eliminate bubbles.

[0009] 3. The electric heating block on the inner wall of the connecting tube of the present invention is embedded in the groove of the gathering ring, which can evenly heat the gathered liquid medicine to prevent the patient from feeling uncomfortable due to low-temperature liquid medicine. The liquid level monitoring sensor monitors the liquid level in real time. When the liquid level is too low, the electric push rod can automatically drive the piston to block the air path to prevent air from entering the blood vessels, forming a double safety protection. 4. The second spring at the bottom of the baffle of the present invention supports the baffle through the support ring, allowing the storage chamber volume to be flexibly adjusted according to the amount of liquid medicine, adapting to different infusion speed requirements. The baffle and the support ring are elastically connected by the second spring to form a retractable storage chamber. When the liquid medicine accumulates, the baffle is pressed down to expand the volume, buffering flow fluctuations. When the liquid medicine decreases, the spring rebounds and pushes the baffle up, reducing residual liquid medicine and improving drug delivery accuracy. To sum up, through the corresponding coordinated use of various structures, manual fine-tuning of the flow rate of the drug solution can be achieved, the air path can be quickly blocked when the liquid level is abnormal or emergency liquid stop is required, and automatic emergency adjustment of pressure and flow can be achieved, which solves the problem that the existing technology can only detect pressure but cannot adjust it quickly. At the same time, the storage cavity formed by the central block and the baffle can temporarily store the drug solution, allowing bubbles to rise and escape under the action of buoyancy, preventing bubbles from entering the patient's blood vessels with the drug solution, and solving the defect that the existing technology is difficult to eliminate bubbles.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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] As attached Figure 1 -Attached Figure 7 The intelligent monitoring infusion pump shown in the figure uses a flow monitoring assembly provided on the connecting tube 1, and the piston 7 in the mounting tube 5 cooperates with the first spring 8, the knob 9 and the electric push rod 10 to form a dual control mechanism. The knob 9 is threadedly connected to the mounting tube 5, and when rotated, it can adjust the preload force of the first spring 8, thereby controlling the initial position of the piston 7 in the mounting tube 5, and realizing manual fine adjustment of the air intake volume; the output end of the electric push rod 10 directly acts on the piston 7, which can quickly drive its displacement to change the size of the opening at the connection between the mounting tube 5 and the air intake tube 6, realizing emergency regulation of pressure and flow when the liquid level monitoring sensor 4 detects an abnormality, solving the problem that the existing technology can only detect pressure but cannot quickly adjust it. The specific structural setting of the component is as follows; The diversion monitoring assembly includes a gathering ring 2 embedded in the connecting tube 1, a center block 11 is provided in the middle of the gathering ring 2, a baffle 3 is provided at the bottom of the center block 11, and a storage cavity is formed between the center block 11 and the baffle 3. Figure 4 、 5 As shown in Figures 6 and 7, the liquid medicine enters the connecting tube 1 and is gathered by the gathering ring 2, which facilitates the gathering ring 2 to conduct heat to properly heat the liquid medicine gathered in the gathering ring 2, thereby avoiding the discomfort caused to the patient by the low temperature of the liquid medicine; a liquid level monitoring sensor 4 is provided on one side of the surface of the connecting tube 1, and a mounting tube 5 is provided on the other side of the connecting tube 1, and the mounting tube 5 is communicated with the connecting tube 1, and an air inlet tube 6 is provided on the outside of the mounting tube 5, as shown in the attached figure. Figure 1 、 2, 3 and 4, the air flow is injected into the mounting tube 5 through the air inlet tube 6, and then injected into the connecting tube 1 through the mounting tube 5, so that the liquid medicine in the bottle flows into the connecting tube 1 due to the pressure difference; a plurality of mounting grooves 12 are provided on the outside of the center block 11, and a diverter plate 13 is embedded in each mounting groove 12, and a diverter cavity 14 is formed between the center block 11 and the gathering ring 2, as shown in the attached Figure 6 As shown, the diverter plate 13 is provided to divert the liquid medicine flowing into the gathering ring 2, so that the liquid medicine can be guided through the diverter plate 13 in the gathering ring 2 and the diverter cavity 14, thereby eliminating the air in the liquid medicine and avoiding bubbles during the liquid medicine delivery. A piston 7 is slidably connected in the mounting cylinder 5. A first spring 8 is provided at one end of the piston 7. A knob 9 is provided at the end of the first spring 8 away from the piston 7. Figure 2 and 3 As shown, the piston 7 is used to block the installation cylinder 5 and the air intake cylinder 6. When the piston 7 is displaced, the size of the opening at the connection between the installation cylinder 5 and the air intake cylinder 6 is adjusted, thereby adjusting the size of the air intake; a knob 9 is provided at one end of the first spring 8 away from the piston 7, and an electric push rod 10 is provided at one end of the installation cylinder 5 away from the knob 9. The knob 9 is threadedly connected to the installation cylinder 5, and the output end of the electric push rod 10 passes through the installation cylinder 5 and extends to one end of the piston 7, as shown in the attached figure. Figure 2 and 3 As shown, by rotating the knob 9, the position of the knob 9 is adjusted to adjust the compression and rebound range of the first spring 8, so as to facilitate the regulation of the displacement stroke of the piston 7 in the mounting cylinder 5, so that the piston 7 can automatically adjust the position of the piston 7 through the elasticity of the first spring 8 itself and the air pressure contained in the medicine bottle, and the electric push rod 10 drives the piston 7 to move, so that the piston 7 blocks the connection between the mounting cylinder 5 and the air inlet cylinder 6 to prevent air pressure from entering the medicine bottle. Furthermore, when the liquid level monitoring sensor 4 cannot detect the liquid medicine, the electric push rod 10 can start to drive the piston 7 to move and block it at a certain time to prevent air from entering the patient's blood vessels.

[0021] A slot 15 is provided on one side of the surface of the gathering ring 2, and an electric heating block 16 is provided on the inner wall of the connecting tube 1. The electric heating block 16 extends into the slot 15. Figure 4 and 5 As shown, the electric heating block 16 and the card slot 15 are used in conjunction with each other to facilitate the positioning of the gathering ring 2 installed in the connecting tube 1, thereby improving the convenience during assembly. The electric heating block 16 is energized to generate heat and transmit it to the gathering ring 2, so as to properly heat the liquid gathered in the gathering ring 2. A plurality of liquid outlets 17 are provided on the baffle 3, and a support ring 18 is provided at the bottom of the baffle 3. Figure 7 As shown, the liquid outlet 17 is provided to facilitate the liquid medicine in the storage cavity between the baffle 3 and the central block 11 to flow out through the liquid outlet 17 .

[0022] The bottom of the baffle 3 is provided with a support ring 18, the bottom of the support ring 18 is provided with a second spring 19, the bottom of the second spring 19 is provided with a vertical cylinder 20, and the top of the second spring 19 is in contact with the support ring 18. Figure 7 As shown, the vertical cylinder 20 serves as a support point, so that the second spring 19 is installed in an embedded form between the vertical cylinder 20 and the support ring 18. At the same time, the elasticity of the second spring 19 itself makes the support ring 18 and the baffle 3 in an elastic state, so that when the liquid medicine in the storage chamber between the baffle 3 and the center block 11 accumulates more and more, the baffle 3 can be displaced downward, which is convenient for adjusting the storage capacity of the liquid medicine in the storage chamber; a joint 21 is provided at the bottom of the vertical cylinder 20, and the vertical cylinder 20 and the joint 21 are both located at the bottom of the connecting cylinder 1, as shown in the attached figure. Figure 1 As shown, the provision of the connector 21 facilitates the installation of the infusion hose by the staff so as to facilitate the discharge of the liquid medicine.

[0023] The top of the connecting tube 1 is provided with a puncture head 22, and the outer side of the puncture head 22 is provided with a limit cover 23, which is placed horizontally on the top of the connecting tube 1 and is connected to the connecting tube 1. Figure 1 As shown, the puncture head 22 is provided so that the liquid medicine in the medicine bottle can be discharged when the puncture head 22 is inserted into the medicine bottle, and the setting of the limiting cover 23 facilitates the installation of the puncture head 22 on the connecting tube 1 to limit the puncture head 22, so that the puncture head 22 can be disassembled and replaced.

[0024] The specific working principle is as follows: the puncture head 22 is inserted into the medicine bottle, and the limit cover 23 limits and fixes the puncture head 22. The liquid medicine in the medicine bottle flows into the connecting tube 1 through the puncture head 22. After the liquid medicine enters the connecting tube 1, it is guided by the inner inclined surface of the gathering ring 2 and gathered toward the center block 11. The gathering ring 2 fits tightly with the inner wall of the connecting tube 1 to form an annular guide space. At this time, the electric heating block 16 preset on the inner wall of the connecting tube 1 is energized and heated. The heat is conducted to the main body of the gathering ring 2 through the contact end face embedded in the card slot 15 of the gathering ring 2. The gathering ring 2 is made of heat-conducting silicone material, which can evenly transfer heat to the liquid medicine flowing through it, so that the temperature of the liquid medicine is heated from about 5°C at room temperature to 15-30°C, thereby preventing the low-temperature liquid medicine from irritating the patient's blood vessels.

[0025] After being gathered, the liquid medicine enters the diversion chamber 14 between the central block 11 and the focusing ring 2. Six mounting slots 12 are evenly spaced along the circumference of the central block 11. Each slot 12 houses an arc-shaped diverter plate 13, forming an angled flow channel between adjacent diverter plates 13. As the liquid medicine flows through the diverter plates 13, it is divided into several thin streams. For example, the flow rate drops from an initial 0.8-1.2 m / s to 0.3-0.5 m / s, significantly reducing turbulence and minimizing bubble formation.

[0026] The diverted liquid flows slowly along a circular path within diversion chamber 14. Because bubbles are less dense than the liquid, they float upward along the inner wall of gathering ring 2, eventually overflowing into the open space above connecting tube 1. The debubbled liquid enters the storage chamber formed by central block 11 and baffle 3 through the opening at the bottom. It rests there for a further 3-5 seconds, allowing any remaining tiny bubbles to rise to the top of the storage chamber, achieving secondary debubbling. To maintain air pressure balance between the medicine bottle and connecting tube 1 and prevent interruption of liquid supply due to negative pressure caused by outflow of liquid, external air flows into the mounting tube 5 through the air inlet tube 6. When the knob 9 is rotated, its threaded engagement with the mounting tube 5 causes the knob 9 to move axially, compressing or relaxing the first spring 8. The elastic force of the first spring 8 is transmitted to the piston 7, causing it to slide within the mounting tube 5, changing its relative position with the interface of the air inlet tube 6: when the piston 7 approaches the interface, the opening area decreases, the amount of air intake decreases, the air pressure in the connecting tube 1 drops, and the speed of liquid supply from the medicine bottle slows down; conversely, the opening area increases, the amount of air intake increases, and the speed of liquid supply increases.

[0027] When the flow needs to be adjusted quickly or the liquid needs to be stopped urgently, the telescopic rod of the electric push rod 10 is extended, directly pushing the piston 7 to overcome the elastic force of the first spring 8 and move quickly, which can instantly adjust the interface opening area to the target value, or completely block the interface, cut off the air intake and stop the liquid supply.

[0028] The liquid level monitoring sensor 4 on the surface of the connecting tube 1 can use the infrared radiation principle to monitor the liquid level of the medicine in the storage chamber in real time, and its monitoring point is located in the middle of the storage chamber. When the liquid level is lower than this point, the sensor outputs an electrical signal to trigger the electric push rod 10 to act: the telescopic rod is fully extended to push the piston 7 to the extreme position, completely blocking the interface between the installation tube 5 and the air inlet tube 6, and preventing external air from entering the connecting tube 1. At the same time, the medicine in the storage chamber flows into the support ring 18 through the liquid outlet 17 evenly distributed on the baffle 3. The second spring 19 between the support ring 18 and the vertical tube 20 gradually rebounds as the amount of medicine decreases, driving the baffle 3 to elastically displace downward, so that the bottom of the storage chamber always maintains a relative height with the liquid outlet 17, ensuring that the medicine continues to flow steadily into the vertical tube 20, and is finally delivered to the patient through the infusion hose connected to the connector 21, avoiding the flow rate from being fast or slow due to liquid level fluctuations.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
