Description

Technical Field

[0001] The present invention relates to the technical field of infusion control, and in particular to an infusion detection and control device for counting infusion volume. Background Art

[0002] Infusion is a common medical treatment method, which directly delivers drugs, nutrients, electrolytes or blood to the patient through infusion tubes and veins. At present, when clinical patients are infused, the amount of infusion liquid required is not entirely the amount of liquid packaging (such as mannitol, sodium bicarbonate solution, etc.), and the dosage of some children and the elderly will also be reduced during infusion (such as levofloxacin hydrochloride, ornidazole sodium chloride, fat emulsion, etc.). Therefore, most clinical nurses will take the following methods to solve the problem: 1. Use a disposable syringe / disposable infusion device to extract the excess part so that the remaining amount in the container meets the treatment amount; 2. Draw the required liquid scale line on the surface of the container and tell the patient to call the nurse when the infusion reaches the line, but the dosage control is usually inaccurate. The above methods not only increase disposable consumables, increase expenditure, but also make nurses spend more time; at the same time, many patients will forget to check the liquid, resulting in excessive infusion, inaccurate treatment dosage, and adverse events.

[0003] In clinical infusion therapy, in order to reduce the work pressure of medical staff, the prior art often uses an infusion alarm with a publication number of CN103432645B, which is used to automatically clamp and stop the infusion tube when the medicine in the infusion tube is finished, so as to prevent air from entering the patient's body through the infusion tube. However, this method can only react when the medicine in the infusion tube is empty, and cannot solve the above-mentioned problem; an infusion alarm with a publication number of CN114949454B is also used to monitor the content of the remaining medicine in the infusion bag at all times. Although this method can solve the above-mentioned problem, it requires direct contact with the medicine, which is easy to cause contamination of the medicine.

[0004] In addition, after the infusion is completed, although the prior art CN114949454B can alarm according to the remaining liquid content in the infusion bag, some liquid often remains at the bottom of the infusion tube dropper (Murphy's dropper), which can easily flow out through the needle after the patient removes the needle, causing pollution to the surrounding environment.

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] The present invention provides Figure 1The infusion detection and control device shown in the figure is used to count the infusion volume, including two drip bucket covers 1 covering the top of the drip bucket 6 and a drip bucket rotating assembly 4 covering the outer end of the infusion tube 7. The drip bucket rotating assembly 4 is equipped with a microcontroller 3 for receiving information sent by the photoelectric sensor 2 to count the medicine drops. Photoelectric sensors 2 are installed below the inside of the two drip bucket covers 1. The photoelectric sensor 2 includes a transmitter and a receiver. The transmitter emits light. When the droplets in the drip bucket 6 pass through the area between the transmitter and the receiver, the intensity of the light is blocked or changed. The receiver detects these changes and converts them into electrical signals and sends them to the microcontroller 3. The counting circuit in the microcontroller 3 (the counting circuit is a mature technical solution in the prior art and will not be further described here) converts it into the number of droplets, thereby achieving the effect of counting the number of medicine drops.

[0042] There are three types of drop coefficients of infusion devices commonly used in clinical practice: 10 drops / ml, 15 drops / ml, and 20 drops / ml. The microcontroller 3 in the present invention is provided with three counting modes, corresponding to the above three drop coefficients respectively. Commonly used liquid medicine dosage parameters are respectively set in each technical mode: 50ml, 75ml, 100ml, 125ml, 150ml, 200ml, etc., and an alarm line is set. When a sufficient amount of liquid is reached, an alarm message is sent to the nurse station for an alarm prompt. Medical staff can also flexibly set the above commonly used liquid medicine dosage parameters and alarm lines according to the infusion requirements of different patients through the operation buttons on the micro alarm 3.

[0043] Taking "the drop coefficient is 15 drops / ml and the required input liquid dosage is 125ml" as an example, the number of drops that need to be dripped into the drip bucket 6 is calculated as follows: 15×125=1875. In other words, if it is necessary to control the input of 125ml of liquid medicine into the patient's body, the alarm line that needs to be alarmed needs to be set to 1875 drops in the microcontroller 3. When the photoelectric sensor 2 counts that the liquid medicine has dripped 1875 drops, the microcontroller 3 sends an alarm signal to the nurse station.

[0044] In addition, during the infusion process, medical staff can observe in real time the amount of medicine that has been infused and the remaining amount of medicine to be infused through the display screen on the microcontroller 3 .

[0045] In order to block the continued delivery of the liquid medicine while the microcontroller 3 sends an alarm signal, the present invention is provided with a clamping stop component 5 for blocking the dripping of the liquid medicine above the inside of the dripping funnel cover 1. The microcontroller 3 can control the clamping stop component 5 to block the continued dripping of the liquid medicine according to statistical data. Specifically, Figure 8As shown, the clamping assembly 5 includes clamping plates 51 respectively located inside the two drip bucket covers 1, and the two clamping plates 51 are symmetrically distributed with the infusion tube 7 as the central axis. A plurality of springs b52 are fixed to one end of the clamping plate 51 away from the infusion tube 7, and one end of the spring b52 is fixed to the inner wall of the drip bucket cover 1. A moving rod 53 is fixed to the side of the top of the clamping plate 51 away from the infusion tube 7. The top of the moving rod 53 penetrates the drip bucket cover 1 and extends out of the top of the drip bucket cover 1. An iron protrusion 55 is fixed to one side of the clamping plate 51. An electromagnet c54 controlled by the microcontroller 3 is fixed inside the drip bucket cover 1. After the electromagnet c54 is energized, it adsorbs the iron protrusion 55. This position is as shown in FIG. Figure 8 As shown, the two clamping plates 51 are respectively located on both sides of the infusion tube 7. When the number of droplets counted in the photoelectric sensor 2 reaches the alarm line, the microcontroller 3 controls the electromagnet c54 to cut off the power, and then the electromagnet c54 no longer absorbs the iron protrusion 55, and the clamping plate 51 will move toward the infusion tube 7 under the action of the elastic force of the compressed spring b52. In this process, the infusion tube 7 will be clamped between the two clamping plates 51 and flattened, thereby preventing the liquid medicine from continuing to drip into the drip bucket 6, so as to accurately control the therapeutic dose of the liquid medicine.

[0046] After the infusion is completed, the medical staff can control the electromagnet c54 to re-energize through the microcontroller 3, and then manually move the moving rod 53 so that the electromagnet c54 can again absorb the iron protrusion 55 on the moving rod 53 for reuse next time. In addition, in order to facilitate the medical staff to move the moving rod 53, the present invention specially processes the top of the moving rod 53 into a spherical shape to increase the contact area between the top of the moving rod 53 and the hand of the medical staff, thereby facilitating the operation of the medical staff.

[0047] Furthermore, while the clamping stop assembly 5 clamps and stops the delivery of the liquid medicine, the microcontroller 3 in the present invention can simultaneously control the drip bucket rotating assembly 4 to flip the drip bucket 6 and the drip bucket cover 1 upward so that the drip bucket 6 and the drip bucket cover 1 are flipped 180°. Fig. 9 and 10 As shown, the liquid level in the drip bucket 6 after flipping is as shown in FIG. Fig.10 As shown, Fig.10 The top of the drip bucket 6 is suspended in the air, which can prevent the liquid medicine in the drip bucket 6 from flowing out through the infusion needle to avoid polluting the surrounding environment, and can also prevent the liquid medicine from continuing to flow into the patient's body, further accurately controlling the liquid medicine treatment dose, killing two birds with one stone;

[0048] Specifically, Figure 2-7As shown, the drip bucket rotating assembly 4 includes two infusion tube cover boxes 41 covering the outer ends of the infusion tube 7, and the contact surfaces of the two infusion tube cover boxes 41 are fixed with magnetic strips 42, which are magnetically attracted together to fix the two infusion tube cover boxes 41 to the outer ends of the infusion tube 7. In addition, in order to fix the infusion tube cover boxes 41 to the outer ends of the infusion tube 7, the present invention provides rubber rings at the position where the top end of the infusion tube cover box 41 contacts the infusion tube 7 and the position where the bottom end of the infusion tube cover box 41 contacts the infusion tube 7, so as to increase the friction between the outer wall of the infusion tube 7 and fix the position of the infusion tube cover box 41;

[0049] Because the drip bucket 6 needs to rotate from the bottom of the infusion tube cover box 41 to the side of the infusion tube cover box 41, the infusion tube 7 will inevitably be pulled during the rotation process. Therefore, the present invention provides a plurality of movable infusion tube guide mechanisms 43 inside each of the infusion tube cover boxes 41, so that the bottom end of the infusion tube 7 is bypassed between the plurality of infusion tube guide mechanisms 43 in an S shape and passes through the bottom end of the infusion tube cover box 41, such as Figure 3 and 4 As shown, during the droplet detection process, part of the infusion tube 7 is located inside the infusion tube cover box 41 in a continuous S shape. When the dropper 6 rotates 180°, the infusion tube 7 is located inside the infusion tube cover box 41 in a straight line, as shown in FIG. Fig.10 As shown, the infusion tube 7 is located inside the infusion tube cover box 41 in a bent form, which can provide a margin for the stretching of the infusion tube 7 during the rotation of the drip bucket 6, thereby ensuring the smooth rotation of the drip bucket 6;

[0050] The specific structure of the infusion tube guide mechanism 43 is as follows: Figure 5-7 As shown, the infusion tube guide mechanism 43 includes a plurality of limit plates 431 installed inside the infusion tube cover box 41, and a round rod 432 is movably connected inside each limit plate 431 through a bearing, and the round rod 432 passes through the limit plate 431. One end of the round rod 432 installed inside one of the infusion tube cover boxes 41 is processed with a square groove, and one end of the round rod 432 installed inside the other infusion tube cover box 41 is processed with a square protrusion, and the square protrusion is adapted to the square groove. When the infusion tube cover box 41 is put on the outer end of the infusion tube 7, the round rods 432 in the two infusion tube cover boxes 41 need to be aligned, and the square protrusion is inserted into the square groove. The infusion tube 7 bypasses the outer end of the spliced ​​round rod 432, and the limit plate 431 outside the round rod 432 is used to limit the position of the infusion tube 7 from both sides.

[0051] In order to limit the round rod 432 and the limiting plate 431 on the inner wall of the infusion tube cover box 41, as shown in FIG. Figure 6 and 7As shown, a limiting block 433 is fixed at one end of the round rod 432, and a plurality of limiting grooves 435 are provided on the inner wall of the infusion tube cover box 41. The limiting block 433 is inserted inside the limiting block 433, so that the limiting disk 431 and the round rod 432 can move along the limiting groove 435 inside the infusion tube cover box 41, and one side of the limiting disk 431 is processed into a plane and the other side is processed into an arc surface. Two springs a434 are fixed on the side of the limiting disk 431 processed into a plane, and the end of the spring a434 away from the limiting disk 431 is fixed to the inner wall of the infusion tube cover box 41, and the initial positions of the limiting disk 431 and the round rod 432 are limited by the spring a434 as shown in FIG. Figure 5 The position shown in the figure can be passed through the plurality of round rods 432 in an S shape. When the drip bucket 6 starts to rotate, the infusion tube 7 will squeeze the round rods 432 located on both sides of the infusion tube cover box 41 toward the middle, so that the round rods 432 can drive the limit plate 431 to move toward the middle and stretch the spring a434 until the round rods 432 and the limit plate 431 are moved to the position shown in the figure. Fig.10 In the position shown, the infusion tube 7 is located in a straight line inside the infusion tube cover box 41.

[0052] In the above process, the rotation of the drip bucket 6 is carried out in two steps. First, the structure for driving the drip bucket 6 to rotate is as follows: Figure 2-7 , 9, 10, including a rotating shaft a44 and a rotating shaft b45 rotatably connected to the top of the two infusion tube cover boxes 41, the rotating shaft a44 and the rotating shaft b45 respectively penetrate the two infusion tube cover boxes 41, and the outer ends of the rotating shaft a44 and the outer ends of the rotating shaft b45 are fixed with a rotating arm a46, and the rotating arm a46 is located outside the infusion tube cover box 41 and is driven to rotate by a driving mechanism a48;

[0053] like Figure 6As shown, the driving mechanism a48 includes a protective shell a487 fixed to the top of the outer end of the infusion tube cover box 41, the number of the protective shells a487 is two, the microcontroller 3 is fixed to the outside of one of the protective shells a487, and the two protective shells a487 are provided with incomplete gears a481 inside, and the two incomplete gears a481 are respectively fixed to the outer ends of the rotating shaft a44 and the outer ends of the rotating shaft b45, and a gear a482 is provided on one side of the incomplete gear a481, and a rotating shaft a483 is fixed in the middle of the gear a482, and one end of the rotating shaft a483 It is movably connected to the infusion tube cover box 41 through a bearing, and a coil spring a484 is provided on the outside of this end of the driving mechanism a48, one end of the coil spring a484 is fixed to the outer wall of the rotating shaft a483, and the other end of the coil spring a484 is fixed to the infusion tube cover box 41, and is used to drive the rotating shaft a483 to rotate, and the other end of the rotating shaft a483 passes through the protective shell a487 and is fixed with a round cover a485, and the round cover a485 is located on the outside of the protective shell a487, and an electromagnet a486 is provided on one side of the inner part of the round cover a485, and the electromagnet a486 is fixed on the protective shell a487;

[0054] After the electromagnet a486 is energized, it attracts the round cover a485 to fix the position of the rotating shaft a483. The positions of the rotating shaft a483 and the incomplete gear a481 fixed by the electromagnet a486 are as shown in FIG. Figure 6 As shown, at this time, the rotating arm a46 is in a vertical downward state and the coil spring a484 is in a stretched state. When the number of droplets counted in the photoelectric sensor 2 reaches the alarm line, the microcontroller 3 will control the round cover a485 to cut off the power, and the stretched coil spring a484 will control the rotation of the rotating shaft a483. Then the rotation of the rotating shaft a483 will drive the gear a482 and the incomplete gear a481 meshing with the gear a482 to rotate. After the incomplete gear a481 rotates 90°, the smooth surface of the outer wall of the incomplete gear a481 will contact the gear a482. At this time, even if the gear a482 continues to rotate, it will not drive the incomplete gear a481 to rotate. The rotating incomplete gear a481 will also drive the rotating shaft b45 and the rotating arm a46 installed at the outer end of the rotating shaft b45 to rotate 90°. At this time, the rotating arm a46 will move to the position as shown in the figure. Fig. 9 and 10 The location shown;

[0055] Secondly, a rotating arm b47 is rotatably connected to the bottom end of the rotating arm a46, and the bottom end of the rotating arm b47 is fixed to one side of the top of the drip bucket cover 1. The rotating arm b47 is driven to rotate by a driving mechanism b49, and a protective shell a487 with a microcontroller 3 fixed on the outer wall has a touch switch 410 fixed on the top of the inner part for controlling the activation of the driving mechanism b49;

[0056] like Figure 6As shown, the driving mechanism b49 includes a rotating shaft b491 rotatably connected to the rotating arm a46, a gear b492 is fixed to the outer end of the rotating shaft b491, an incomplete gear b494 is meshed at the bottom of the gear b492, a shaft 498 is fixed in the middle of the incomplete gear b494, one end of the shaft 498 passes through the bottom end of the rotating arm a46 and is fixed to the top end of the rotating arm b47, a protective shell b497 is fixed to the outside of the rotating arm a46, a coil spring b493 is fixed to the outer end of the rotating shaft b491, and the coil spring b49 3 is fixed to the protective shell b497, and a round cover b496 is fixed to the end of the rotating shaft b491 away from the coil spring b493. The end of the rotating shaft b491 passes through the protective shell b497 and the round cover b496. An electromagnet b495 is arranged inside the round cover b496. The electromagnet b495 is fixed to the side of the protective shell b497 away from the rotating arm a46. After the electromagnet b495 is energized, it adsorbs the round cover b496 to fix the position of the rotating shaft b491. The on and off of the electromagnet b495 is controlled by the touch switch 410;

[0057] The initial position of the rotating arm b47 is as follows Figure 2-6 As shown, they are all in the vertical downward position, at this time, the coil spring b493 is in a stretched state, and when the rotating arm a46 rotates 90°, it will contact the touch switch 410, and the electromagnet b495 is powered off by controlling the touch switch 410, and then the stretched coil spring b493 will drive the rotating shaft b491 and the gear b492 installed at the outer end of the rotating shaft b491 to rotate, and then the gear b492 drives the incomplete gear b494 meshing with it to rotate 90°. After the incomplete gear b494 rotates 90°, the gear b492 will contact the smooth surface of the outer wall of the incomplete gear b494. At this time, even if the gear b492 continues to rotate, it will not drive the incomplete gear b494 to rotate. In this process, the rotating incomplete gear b494 will synchronously drive the shaft 498 and the rotating arm b47 fixed to the shaft 498 to rotate 90°, so that the rotating arm b47 and the drip bucket cover 1 and the drip bucket 6 at the bottom of the rotating arm b47 can rotate to the position shown in the figure. Fig. 9 and 10 The position shown in the figure achieves the purpose of rotating the drip bucket 6 by 180°. The flipped drip bucket 6 can not only prevent the liquid medicine inside it from flowing out of the infusion needle, but also prevent the liquid medicine from flowing into the patient's body.

[0058] In addition, after the infusion is completed, the medical staff can manually rotate the rotating shaft b491 in the opposite direction, and use the rotating shaft b491 to drive the gear b492, the incomplete gear b494, and the shaft 498 to rotate in the opposite direction, thereby driving the rotating arm b47 to rotate in the opposite direction to a position parallel to the rotating arm a46, and then manually rotate the rotating shaft a483 in the opposite direction, and use the rotation of the rotating shaft a483 to drive the incomplete gear a481 and the gear a482 to rotate in the opposite direction, and at the same time stretch the coil spring a484 to reset the rotating arm a46 to a vertical downward state. During the resetting process of the rotating arm a46, it no longer contacts the touch switch 410, and then the electromagnet b495 will be energized again, so that it can absorb and fix the circular cover b496 fixed at the outer end of the rotating shaft b491 to fix the position of the rotating arm b47, and then the microcontroller 3 controls the electromagnet a486 to be energized, and the electromagnet a486 is used to absorb and fix the circular cover a485 fixed at the outer end of the rotating shaft a483 to fix the position of the infusion tube guide mechanism 43. In order to facilitate medical staff to rotate the rotating shaft a483 and the rotating shaft b491 in the present invention, a handle for easy rotation is fixed at one end of the rotating shaft a483 and one end of the rotating shaft b491, thereby facilitating the operation of medical staff.
