Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an intravenous infusion therapy monitoring device. Background Art

[0002] During clinical infusion, generally, a monitoring device is used to monitor the infusion flow rate in real time to prevent the liquid from entering the patient's body too fast or too slow. At the same time, the infusion process is controlled in real time. When the infusion is abnormal or the liquid is about to run out, the device will automatically alarm and cut off the passage to ensure the safety and continuity of the infusion.

[0003] In actual use, bubbles will randomly generate in the infusion tube during infusion. When the monitoring device detects that the bubbles inside the infusion tube exceed the normal range, the monitoring device will automatically alarm and cut off the passage to remind the medical staff. At this time, the medical staff usually need to wind and squeeze the infusion tube segment by segment from top to bottom with their fingers, and push the bubbles to move along the tube in this manual way to finally eliminate the bubbles. The operation is rather cumbersome, which not only increases the workload of the medical staff, but also may affect the overall work efficiency. For this reason, we propose an intravenous infusion therapy monitoring device. Summary of the Invention

[0004] The purpose of the present invention is to provide an intravenous infusion therapy monitoring device to solve the problem proposed in the above background art that bubbles will randomly generate in the infusion tube during infusion.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 Please refer to Figures 1 to 12 , the present invention provides a technical solution: an intravenous infusion treatment monitoring device, including: An infusion stand 1, the infusion stand 1 suspends the infusion bottle 2, so that there is a height difference between the infusion bottle 2 and the patient; A defoaming mechanism 3, the defoaming mechanism 3 is installed on one side of the infusion stand 1, the defoaming mechanism 3 is penetrated by the infusion tube 4, the defoaming mechanism 3 enriches the bubbles in the infusion tube 4 located therein, and when the bubbles in the infusion tube 4 affect normal infusion, the defoaming mechanism 3 shakes out the bubbles in the infusion tube 4; A monitoring mechanism 10, the monitoring mechanism 10 is installed on one side of the infusion stand 1, the infusion bottle 2 is located in the monitoring mechanism 10, the monitoring mechanism 10 monitors the diameter and weight of the infusion bottle 2, and adjusts the height difference between the infusion bottle and the patient according to the diameter and weight of the infusion bottle; Lifting mechanism 11, the lifting mechanism 11 is installed between the infusion stand 1 and the monitoring mechanism 10. When the weight of the infusion bottle 2 decreases, the lifting mechanism 11 drives the infusion bottle 2 to move upward. The lifting mechanism 11 synchronously adjusts the upward movement height according to the liquid level decrease amount of the infusion bottle 2, so that the height difference between the liquid surface of the infusion bottle 2 and the patient is in a relatively balanced state.

[0020] During use, move the infusion stand 1 to a designated location through the universal wheels at the bottom and lock it. Select the corresponding medicine according to the patient's condition. Place the infusion bottle 2 on the monitoring mechanism 10, connect the infusion tube 4 to the infusion bottle 2, and then install the infusion tube 4 inside the receiving groove 32, and then the patient can be treated by pricking the needle.

[0021] The defoaming mechanism 3 includes a square block 31 installed on the left side of the infusion stand 1. A receiving groove 32 is opened in the middle of the square block 31. Three sliding grooves 33 are opened on the front side of the square block 31 and on the left side of the receiving groove 32. Three photoelectric sensors 34 are evenly distributed inside the square block 31 and on the right side of the receiving groove 32. A vibration motor 35 is installed at the inner bottom of the square block 31. Two sliding rods 36 are fixedly connected inside the receiving groove 32. A first spring 37 is sleeved on one side of the outer part of each of the two sliding rods 36. A first electromagnet 38 is slidably connected to the other side of the outer part of each of the two sliding rods 36. A metal column 39 is fixedly connected to the left side of the first electromagnet 38. The outer side of the metal column 39 is slidably connected to a fixed block 310. The left side of the fixed block 310 is fixedly connected to the inner wall of the receiving groove 32. A first electrode plate 311 is fixedly connected inside the fixed block 310. An alarm mechanism 9 is arranged on the right side of the defoaming mechanism 3.

[0022] During use, when infusing, air bubbles will be carried by the solution to accumulate inside the infusion tube 4 at the raised part of the accommodating groove 32. It is monitored by three set optoelectronic sensors 34. When the accumulation of air bubbles exceeds the normal range, the optoelectronic sensor 34 at the raised part will detect an abnormal change, and its feedback signal is different from the signals of the other two optoelectronic sensors 34. At this time, the signal difference will cause different magnetic force changes in the corresponding electromagnets. The magnetic force change of the electromagnet directly affects the position of the middle electromagnet, thereby triggering the displacement of the middle electromagnet. The displacement of the middle electromagnet drives the metal column 39 to move synchronously. The movement of the metal column 39 will compress the first spring 37. As the metal column 39 is inserted into the fixing block 310 and contacts the first electrode plate 311, the metal column 39 serves as a conductor to complete the connection of the circuit. At this time, when the optoelectronic sensor 34 at the raised part detects more air bubbles, the feedback signal will cause the first electromagnet 38 to move towards the fixing block 310. As the first electromagnet 38 moves, the depth of the metal column 39 inserted into the fixing block 310 increases, the loop of the circuit becomes shorter, the resistance decreases, and the current increases. This change will increase the vibration frequency of the vibration motor 35, achieving the ability to automatically adjust the frequency of the vibration motor 35 according to the number of air bubbles, ensuring that the accumulation of air bubbles is effectively controlled and preventing the infusion effect from being affected due to excessive accumulation of air bubbles. When the number of air bubbles returns to the normal level, the elastic force of the first spring 37 will cause the first electromagnet 38 to reset. The reset process drives the metal rod to disengage from the fixing block 310 and return to the initial position, thus completing an automatic adjustment process (the vibration time depends on the amount of air bubbles. When there are many air bubbles, the vibration force is large and the vibration time is set to 2 s. When there are fewer air bubbles, the vibration frequency is low and the vibration time is 4 s. The large infusion bottle 2 has a large area and fast defoaming, and the infusion time is long, with fewer air bubbles, low vibration frequency, and long vibration time. The small bottle is the opposite).

[0023] The monitoring mechanism 10 includes a mounting block 101, a plurality of third springs 102, and an elastic arc ring 103. The bottom of the mounting block 101 is fixedly connected to the top right side of the defoaming mechanism 3. The bottom ends of the third springs 102 are fixedly connected to the top left side of the defoaming mechanism 3. The elastic arc ring 103 is arranged outside the infusion bottle 2. The left side of the mounting block 101 is respectively provided with a first mounting groove 104, a second mounting groove 105, and a third mounting groove 106. The inside of the first mounting groove 104, the second mounting groove 105, and the third mounting groove 106 are all fixedly connected with fourth springs 107. The other ends of the fourth springs 107 are fixedly connected with second electrode plates 108. The top ends of the third springs 102 are fixedly connected with a placement plate 109. The outside of the placement plate 109 is slidably connected with a housing 1010. The bottom of the housing 1010 is fixedly connected to the top left side of the lifting mechanism 11. The top right side of the elastic arc ring 103 is fixedly connected with two cylindrical blocks 1011.

[0024] During use, depending on the model of the infusion bottle 2, the size, weight, volume, and liquid descent rate are all different. When using a large infusion bottle 2 (the capacity of the large infusion bottle 2 is 500 ml), first, put the elastic arc-shaped ring 103 on the outside of the infusion bottle 2 (the elastic arc-shaped ring 103 can adapt to infusion bottles 2 of different sizes. The large infusion bottle 2 has a large volume, so a larger area is required to enclose it, and it is inserted shallower into the installation block 101). Insert one end of the connecting cylinder block 1011 of the elastic arc-shaped ring 103 into the internal installation groove three 106. At this time, it is in the first gear position. Then place the bottom end of the infusion bottle 2 on the placement plate 109. Under the action of the gravity of the infusion bottle 2 itself, a certain pressure is exerted on the placement plate 109. The placement plate 109 will transmit the received pressure to the spring three 102, causing the spring three 102 to be compressed. As a result, the cylinder block 1011 is located at the lowest point of the installation groove three 106. When the liquid level in the infusion bottle 2 drops by 50 ml, under the elastic force of the spring three 102, the placement plate 109 is driven to move upward. The upward movement of the placement plate 109 drives the infusion bottle 2 to move synchronously. The movement of the infusion bottle 2 drives the elastic arc-shaped ring 103 to move inside the installation groove three 106, causing the two cylinder blocks 1011 to contact the two second electrodes respectively. At this time, the lifting mechanism 11 is powered on and starts working for 5 s and then stops, thereby driving the infusion bottle 2 to move up and down. When the liquid level in the infusion bottle 2 drops by more than 50 ml, under the action of the spring three 102, the elastic arc-shaped ring 103 is driven to move upward, which in turn drives the cylinder block 1011 to move upward and push the second electrode plate 108 to compress the spring four 107 to one side. As the liquid level drops, the cylinder block 1011 will move upward, ensuring that the infusion bottle 2 can continue to adjust its position according to the liquid level change to ensure smooth liquid delivery. When using a small infusion bottle 2, insert the elastic arc-shaped ring 103 into the corresponding installation groove. Since the small infusion bottle 2 has a smaller volume and a capacity of 100 ml, the insertion depth is deeper. At this time, it is in the third gear position, and the degree of compression of the spring three 102 is relatively light. In the third gear, when the cylinder block 1011 contacts the second electrode, the rotation time of the control lifting mechanism 11 is 15 s. At the same time, the distances between the second electrodes inside the installation groove one 104, the installation groove two 105, and the installation groove three 106 are from large to small, and the depths are from deep to shallow, corresponding to different gear sizes, realizing the automatic adjustment of the working gear and working time of the lifting mechanism 11 according to the size, weight, and liquid level change of the infusion bottle 2.

[0025] The lifting mechanism 11 includes a driving motor 111 installed inside the infusion rack 1. The output end of the driving motor 111 is fixedly connected with a screw rod 112. A threaded block 113 is threadedly connected to the outside of the screw rod 112. The outside of the threaded block 113 is fixedly connected with a lifting plate 114.

[0026] During use, after the drive motor 111 is powered on, the screw 112 starts to rotate. The rotation of the screw 112 drives the threaded block 113 to move, and then drives the infusion bottle 2 to move upward through the lifting plate 114.

[0027] The alarm mechanism 9 includes a mounting frame 91, a timer 93, and a limiting rod 92. The left side of the mounting frame 91 is fixedly connected to the left side of the square block 31. The left side of the timer 93 is mounted and connected to the right side of the square block 31. Both ends of the limiting rod 92 are fixedly connected to the inside of the square block 31. Two second springs 94 are fixedly connected to the inner bottom wall of the mounting frame 91. The tops of the two second springs 94 are fixedly connected to a connecting plate 95. A second electromagnet 96 is mounted on the top of the connecting plate 95. A magnetic coil 97 is mounted on the inner top wall of the mounting frame 91.

[0028] During defoaming, both the square block 31 and the infusion tube 4 vibrate. When the square block 31 vibrates, under the elastic force of the second spring 94, the connecting plate 95 slides on the outside of the limiting rod 92, and drives the top of the second electromagnet 96 to reciprocate up and down inside the electromagnetic coil, causing the electromagnet to cut the magnetic induction lines inside the magnetic coil 97 to generate an electric current, which is transmitted to the timer 93 through a wire, making the timer 93 powered on. The timer 93 starts timing after receiving the current. When the timer 93 exceeds the preset threshold of 4 seconds, the timer 93 triggers the alarm system to make a sound, reminding the staff that there is a malfunction in the defoaming mechanism 3.

[0029] Embodiment 2 In the second embodiment, other structures remain unchanged. Different from the first embodiment, one end of the first spring 37 is fixedly connected to the left side of the first electromagnet 38, and the other end of the first spring 37 is fixedly connected to the inner wall of the sliding groove 33. The first spring 37 provides an elastic force for the reset of the first electromagnet 38. The outer side of the first electromagnet 38 is slidably connected inside the sliding groove 33, enabling the first electromagnet 38 to move stably. The shape of the accommodating groove 32 is convex in the middle, so that the air bubbles during infusion can be concentrated and accumulated at the convex part. The number of the photoelectric sensors 34 corresponds to that of the first electromagnets 38, and they are symmetrically distributed on both sides of the accommodating groove 32. The two cooperate with each other to detect the number of air bubbles in the infusion tube 4. The outer side of the connecting plate 95 is slidably connected to the outer side of the limiting rod 92, which can play a role in limiting the connecting plate 95. There are two sets of the first installation groove 104, the second installation groove 105 and the third installation groove 106 respectively. The number of the fourth springs 107 and the second electrode plates 108 arranged inside the first installation groove 104, the second installation groove 105 and the third installation groove 106 are different. The distances between the second electrode plates 108 corresponding to different gears are different. The outer sides of the second electrode plates 108 are slidably connected inside the installation blocks 101, enabling the second electrode plates 108 to move stably. The outer side of the threaded block 113 is slidably connected inside the infusion stand 1, enabling the threaded block 113 to move stably. The top of the screw rod 112 is rotatably connected to the inner top wall of the infusion stand 1, enabling the screw rod 112 to move stably. At the same time, the threads on the surface of the screw rod 112 are relatively dense.
