Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent infusion reminder system. Background Art

[0002] In current medical treatment, infusion has become a very common medical condition. Infusion refers to the method of injecting large doses of injection into the body through intravenous drip, which is also called intravenous drip.

[0003] Because most infusions require the continuous infusion of several bottles of injection solution, during daytime infusions, because patients have family members accompanying them or fellow patients remind each other, usually before the injection solution is about to run out, someone will call medical staff to replace the injection solution or remove the needle for infusion in time. Therefore, it is basically impossible for the infusion to be not stopped after it is completed. However, for some patients who need infusion at night, especially when the infusion time is later than 10 o'clock in the evening, fellow patients and patients gradually fall asleep, and some family members are also prone to drowsiness. It is difficult to ensure that someone can call medical staff in time for infusion late at night, and there are very few medical staff on duty at night. Once the medical staff forget to take the initiative to check the patient's infusion situation late at night, there is a situation where they forget to change the injection solution for the patient in time or forget to stop the infusion and remove the needle in time; in addition, when medical staff encounter emergencies at night, such as a sudden worsening of a patient's condition, or an emergency situation that requires immediate medical participation, the medical staff who have withdrawn to deal with the emergency are prone to forget to check the infusion situation of the patient who is receiving the infusion or stop the infusion to remove the needle beyond the need due to the influence of new affairs. If the infusion is not stopped in time, the infusion tube will be connected to the atmosphere after the injection is completed, causing air to enter the blood vessels, which will bring psychological burden to the patient and medical staff at the least, and air embolism at the worst, posing a threat to the patient's life safety.

[0004] Therefore, it is urgent to design an intelligent infusion reminder system to monitor the infusion situation in time and feed back the infusion situation to medical staff. Summary of the invention

[0005] The present invention is intended to provide an intelligent infusion reminder system to solve the current problem of nighttime infusion that medical staff easily forget or their time is occupied by other matters and fail to stop the patient's infusion in time.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] An intelligent infusion reminder system includes an infusion monitoring module, an infusion control module, and a mobile display. The infusion monitoring module is used to detect the remaining amount of the infusion bag. The infusion control module is used to display the remaining amount of the infusion bag on the mobile display after the infusion monitoring module detects that the remaining amount of the infusion bag is lower than a preset value. The infusion control module includes a controller, a driver, and a liquid path adjuster. The liquid path adjuster includes a fixed column and an outer sleeve that sleeves the fixed column. There is an annular gap between the outer sleeve and the fixed column. The annular gap is used to provide a placement space for the infusion tube. A pressure strip is fixedly connected to the inner wall of the outer sleeve. The pressure strip can flatten the infusion tube against the surface of the fixed column after the outer sleeve rotates. The driver is used to drive the outer sleeve to rotate. The controller is used to control the driver to drive the outer sleeve to rotate to flatten the infusion tube to a non-flow state after the infusion monitoring module detects that the remaining amount of the infusion bag is lower than the set value.

[0008] The principle and advantages of this solution are as follows: In actual application, when using this embodiment, when infusing a patient at night, by installing a liquid path adjuster on the infusion tube, when the remaining amount of the infusion bag reaches the preset value, for example, the preset amount when an injection is almost used up, the situation that the injection is about to be exhausted is informed to the medical staff through the mobile display by the infusion control module. The medical staff can carry the mobile display with them to know the infusion situation in real time. When the medical staff are busy with other affairs and fail to take the needle for the infusion patient in the first time, the driver drives the outer sleeve of the liquid path adjuster to rotate, so that the pressure strip presses on the infusion tube, preventing the continuous flow of the infusion tube. After the infusion tube is blocked, the human blood vessel cannot form a connection with the outside world, so the injection in the infusion tube will not enter the patient's body, that is, the problem that the air in the infusion tube enters the blood vessel due to the medical staff's failure to pull out the needle in time is avoided.

[0009] Preferably, as an improvement, the pressure strip includes a flattening section and a pre-pressing section. The distance between the flattening section and the surface of the fixed column is a fixed-length distance. The distance between the pre-pressing section and the surface of the fixed column is greater than the distance between the flattening section and the fixed column, and the distance between the pre-pressing section and the surface of the fixed column increases as it is farther away from the flattening section. When the infusion monitoring module detects that the remaining amount of the infusion bag is lower than the warning value, a reminder message is sent to the mobile display through the controller, and at the same time, the driver is controlled to start, so that the outer sleeve rotates to make the pre-pressing section of the pressure strip press on the infusion tube. When the infusion monitoring module detects that the remaining amount of the infusion bag is lower than the warning value, an alarm message is sent to the mobile display through the controller, and at the same time, the driver is controlled to start, so that the outer sleeve rotates to make the flattening section of the pressure strip press on the infusion tube.

[0010] Beneficial effects: When adopting this solution, through the structural setting of the pressing strip, the pressing strip can flatten the infusion tube to a certain extent through the pre-pressing section to reduce the infusion speed of the infusion tube, providing more time for medical staff to reach the patient's side; and when the medical staff really cannot reach the patient's side in time and the infusion reaches the warning value, through the continuously rotating pressing strip, the flattening section of the pressing strip completely flattens the infusion tube to a non-flow state, preventing air from entering the patient's blood vessel. At the same time, whether the remaining amount of the infusion bag reaches the warning value or the warning limit, the medical staff can timely process the infusion according to the reminder situation and alarm information displayed on the mobile display carried with them, further reducing the probability of air entering the patient's body.

[0011] Preferably, as an improvement, the number of the pressing strips is three, and the three pressing strips are arranged at different positions on the inner wall of the outer sleeve. The three pressing strips are successively the pressing strip one, the pressing strip two and the pressing strip three in the circumferential direction of the outer sleeve; two infusion tubes can be installed on the fixed column at the same time, and each infusion tube corresponds to an infusion bag. The two infusion tubes include the infusion tube one and the infusion tube two. When the pressing strip one does not press the infusion tube one, the flattening section of the pressing strip three presses the infusion tube two; when the pressing strip one just flattens the infusion tube one to a non-flow state, the infusion tube two is located between the pressing strip two and the pressing strip three, and the distance between the flattening sections of the pressing strip three and the pressing strip two is less than the length of the flattening section of the pressing strip one, so that when the flattening section of the pressing strip two presses the infusion tube two, the flattening section of the pressing strip one still presses tightly on the infusion tube one.

[0012] Beneficial effects: When adopting this solution, through the setting of the pressing strip one, the pressing strip two and the pressing strip three, the setting of one liquid path adjuster can switch the infusion conditions of two infusion bags. Specifically, after the remaining amount of the infusion bag connected to the infusion tube one reaches the warning value, the controller automatically controls the driver to drive the outer sleeve to rotate, so that the pressing strip one rotates to the flattening section to flatten the infusion tube and make the infusion tube one in a non-flow state, and the pressing strip three originally pressing on the infusion tube two also moves away. At this time, the infusion tube two is located in the annular gap between the pressing strip two and the pressing strip three. That is, after the infusion tube one is completely blocked, the infusion tube two starts to infuse, realizing the automatic switching of the infusion of two infusion bags, reducing the time consumed by medical staff in replacing the infusion bag, and at the same time improving the intelligent level.

[0013] In addition, because the pressing strips are arranged successively, and the distance between the flattening sections of the pressing strip three and the pressing strip two is less than the length of the flattening section of the pressing strip one, when the outer sleeve rotates to the flattening section of the pressing strip two to press the infusion tube two, the flattening section of the pressing strip one still presses tightly on the infusion tube one, ensuring the complete blocking of the two infusion tubes after the infusion is completed and preventing air from entering the patient's blood vessel.

[0014] Preferably, as an improvement, a heater is provided inside the fixed column. Two spiral grooves are provided on the surface of the fixed column. One spiral groove is used to place the first infusion tube, and the other spiral groove is used to place the second infusion tube. A limiting groove is provided on the bottom surface of the fixed column. A smooth section is provided at the bottom of the fixed column. The pressing strip is opposite to the smooth section of the fixed column.

[0015] Beneficial effects: The heater directly transfers heat to the fixed column, and the infusion tubes are placed along the spiral grooves, so that the length of the infusion tubes in the liquid path adjuster is longer, which is convenient for heating the infusion tubes. When infusing at night, even if the drug is thick, the fluidity of the injection can be increased by heating, improving the infusion effect. At the same time, when the environmental temperature is low (if the temperature of the injection is too low, it will cause discomfort to the patient, such as making the patient receiving the infusion feel cold), it can also heat the injection to ensure the comfort of the infusion.

[0016] In addition, after the infusion tubes of this solution come out of the spiral grooves, they pass through the smooth section and finally lead out from the limiting groove, which ensures that the spiral arrangement prolongs the heating time during the infusion process of the infusion tubes, and also ensures that the pressing strip can cooperate with the smooth section to flatten the infusion tubes on the smooth section. At the same time, the limiting groove ensures that the infusion tubes will not move randomly during the process of squeezing the infusion tubes, ensuring that the control of the infusion situation of the pressing strip on the infusion tubes is not affected.

[0017] Preferably, as an improvement, the outer sleeve includes two semi-cylindrical shells, the two semi-cylindrical shells are rotatably connected, and the free ends of the two semi-cylindrical shells that can approach each other are buckled through a provided connection structure.

[0018] Beneficial effects: When adopting this solution, it is convenient for medical staff to wind the infusion tubes in the spiral grooves and then put the outer sleeve on the fixed column, simplifying the operation.

[0019] Preferably, as an improvement, an external gear ring is provided on the outer surface of one of the semi-cylindrical shells, and a driving gear is fixed to the output end of the driver, and the driving gear can mesh with the external gear ring.

[0020] Beneficial effects: Adopting this solution can simplify the installation and connection relationship between the driver and the liquid path adjuster, reducing costs.

[0021] Preferably, as an improvement, heat insulation cotton is provided on the inner wall of the semi-cylindrical shell, and aluminum foil is pasted on the surface of the heat insulation cotton.

[0022] Beneficial effects: It can improve the heat preservation of the temperature of the heater by the liquid path adjuster, reduce the energy consumption of the heater, and at the same time, through the setting of the aluminum foil, on the basis of ensuring heat conduction, ensure that the outer sleeve can be rotated more easily.

[0023] Preferably, as an improvement, the infusion monitoring module includes a gravity sensor or a pressure sensor.

[0024] Preferably, as an improvement, the infusion monitoring module includes a liquid level sensor, which is used to monitor the liquid level height of the infusion bag and transmit the detected information to the controller.

[0025] Preferably, as an improvement, the mobile display can broadcast the corresponding information content in a voice manner when receiving reminder information and alarm information. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is a further detailed description through specific implementation manners:

[0041] The reference numerals in the accompanying drawings of the specification include: infusion rack 100, gravity sensor 11, liquid level sensor 12, auxiliary member 13, driver 10, driving gear 101, liquid path adjuster 20, fixed column 21, spiral groove 211, smooth section 212, cover plate 213, limiting groove 214, guiding groove 215, outer sleeve 22, heater 23, pressing strip 24, pressing strip one 241, pressing strip two 242, pressing strip three 243, external gear ring 25, heat preservation cotton 26, mounting plate 30, first infusion tube 40, second infusion tube 50, first infusion bag 60, second infusion bag 70, three-way pipe 80, drip tube 90.

[0042] The embodiment is basically as shown in the attached Figures 1 to 14 As shown, an intelligent infusion reminder system includes an infusion monitoring module, an infusion control module, and a mobile display. The mobile display and the infusion monitoring module are both connected to the infusion control module. The mobile display is characterized by being light in weight and small in size, which is convenient for medical staff to carry around. The infusion monitoring module is used to detect the remaining amount of the infusion bag and send the remaining amount to the infusion control module. The infusion control module is used to display the remaining amount of the infusion bag on the mobile display and conduct voice broadcast to inform medical staff after the infusion monitoring module detects that the remaining amount of the infusion bag is lower than the preset value of the infusion control module.

[0043] The remaining amount of the infusion bag can be measured by gravity or liquid level height. When using the remaining weight or remaining weight as the monitoring index, the infusion monitoring module can adopt a gravity sensor 11 or a pressure sensor. As Figure 1 shown, when in use, the gravity sensor 11 or the pressure sensor is fixed on the infusion rack 100, and there is a hook at the lower end of the gravity sensor 11 or the pressure sensor, and the infusion bag is hung on the hook; when the remaining amount is measured by the liquid level height, the infusion monitoring module can adopt a liquid level sensor 12 to illustrate the remaining amount of the infusion bag through the height of the liquid level. As Figure 2 shown, the liquid level sensor 12 is relatively stationary with respect to the position of the infusion bag. The specific method can be to fix an auxiliary member 13 at the rigid structure part of the infusion bag (such as installing the auxiliary member 13 on the ventilation pipe of the infusion bag), and the liquid level sensor 12 is fixed on the auxiliary member 13. The number of liquid level sensors 12 installed on each infusion bag is two to monitor the warning liquid level height and the warning liquid level height of the infusion bag.

[0044] The infusion control module includes a controller, a driver 10, and a liquid path adjuster 20. An installation plate 30 is connected to an infusion rack 100 for hanging an infusion bag in a detachable connection manner. The controller, the driver 10, and the liquid path adjuster 20 can all be installed on the installation plate 30.

[0045] The driver 10 uses a servo motor, and a driving gear 101 is fixed on the output shaft of the servo motor. The driver 10 is electrically connected to the controller.

[0046] Combined Figures 4 to 10 , the liquid path adjuster 20 includes a fixed column 21 and an outer sleeve 22 that sleeves the fixed column 21. A heater 23 is installed inside the fixed column 21. Two helical grooves 211 with the same helix direction are machined on the upper section of the outer periphery of the fixed column 21. A smooth section 212 is machined on the lower section of the outer periphery of the fixed column 21. The bottom of the helical groove 211 and the smooth section 212 are located on the same cylindrical surface. Covers 213 are fixed at the top and bottom of the fixed column 21. Two limiting grooves 214 are machined on each cover 213. The limiting grooves 214 are U-shaped, and the U-shaped openings of the limiting grooves 214 face the inner wall of the outer sleeve 22. A guiding groove 215 communicates with the top of the helical groove 211, and the guiding groove 215 communicates with the limiting groove 214 to facilitate the infusion tube to enter from the limiting groove 214 at the top and then be placed into the helical groove 211 through the guiding groove 215. The connecting line of the ends of the two helical grooves 211 passes through the center of the fixed column 21, that is, the guiding groove 215 is located on both sides of the fixed column 21 and is 180 degrees.

[0047] Combined Figures 6 to 8 , two infusion tubes can be installed on the fixed column 21 at the same time. Each infusion tube corresponds to an infusion bag. The two infusion tubes include an infusion tube one 40 and an infusion tube two 50 (the infusion bag connected to the infusion tube one 40 is called an infusion bag one 60, and the infusion bag connected to the infusion tube two 50 is called an infusion bag two 70). The cross-section of each helical groove 211 is U-shaped. One of the two helical grooves 211 is used to place the infusion tube one 40, and the other is used to place the infusion tube two 50.

[0048] Combined Figure 6 , there is an annular gap between the inner wall of the outer sleeve 22 and the smooth section 212 of the fixed column 21. After the infusion tube is led out from the helical groove 211, it passes through the annular gap and then is led out from the limiting groove 214 on the bottom cover 213 of the fixed column 21.

[0049] A pressing strip 24 is fixed on the outer sleeve 22. The pressing strip 24 faces the smooth section 212 of the fixed column 21. The number of pressing strips 24 is three, and the three pressing strips 24 are arranged at different positions on the inner wall of the outer sleeve 22. The pressing strip 24 can flatten the infusion tube against the surface of the fixed column 21 after the outer sleeve 22 rotates.

[0050] KnotFigure 9 and Figure 10 , the three pressing strips 24 are the first pressing strip 241, the second pressing strip 242 and the third pressing strip 243 in sequence along the circumferential direction of the outer sleeve 22; the first pressing strip 241 is near the first infusion tube 40, and the second pressing strip 242 and the third pressing strip 243 are near the second infusion tube 50. The first pressing strip 241, the second pressing strip 242 and the third pressing strip 243 all include a flattened section and a pre-pressing section integrally formed. The distance between the flattened section and the surface of the fixed column 21 is a fixed-length distance. The distance between the pre-pressing section and the surface of the fixed column 21 is greater than the distance between the flattened section and the fixed column 21, and the distance between the pre-pressing section and the surface of the fixed column 21 increases as it is farther away from the flattened section. In this embodiment, an arc transition surface for transitioning to the flattened section is provided on the pre-pressing section. The distance between the flattened sections of the third pressing strip 243 and the second pressing strip 242 is less than the length of the flattened section of the first pressing strip 241,

[0051] An external gear ring 25 is installed on the outer sleeve 22. The external gear ring 25 can be engaged with the driving gear 101. After the driver 10 is started, the outer sleeve 22 can be driven to rotate through the driving gear 101. When the outer sleeve 22 rotates to a position where the first pressing strip 241 does not press the first infusion tube 40, the flattened section of the third pressing strip 243 presses the second infusion tube 50 tightly. At this time, the first infusion tube 40 is in a state of being able to flow, that is, as Figure 11 shown. When the infusion bag corresponding to the first infusion tube 40 finishes infusion, the driver 10 is controlled to start, driving the outer sleeve 22 to rotate. All the pressing strips 24 on the outer sleeve 22 rotate synchronously, so that when the flattened section of the first pressing strip 241 just presses the first infusion tube 40 until it is not flowing, and the second infusion tube 50 is located between the second pressing strip 242 and the third pressing strip 243. At this time, the first infusion tube 40 is not flowing, while the second infusion tube 50 is in a state of being able to flow, that is, as Figure 12 shown. When the infusion bag corresponding to the second infusion tube 50 also finishes infusion or needs to stop infusion, the driver 10 is controlled to drive the outer sleeve 22 to continue rotating, so that the second pressing strip 242 gradually presses the second infusion tube 50. Because the distance between the flattened sections of the third pressing strip 243 and the second pressing strip 242 is less than the length of the flattened section of the first pressing strip 241, when the flattened section of the second pressing strip 242 moves to press the second infusion tube 50, the flattened section of the first pressing strip 241 still presses tightly on the first infusion tube 40, that is, it realizes that the first infusion tube 40 and the second infusion tube 50 are both in a non-flow state, that is, as Figure 14 shown.

[0052] Combined with Figure 9 , the outer sleeve 22 includes two semi-cylindrical shells that are rotatably connected to each other. The free ends of the two semi-cylindrical shells that can approach each other are buckled through a provided connection structure. It is convenient for medical staff to put the outer sleeve 22 on the fixed column 21 by buckling after winding the infusion tube around the fixed column 21, reducing the assembly difficulty of the liquid path adjuster 20.

[0053] Combined with Figure 6 andFigure 9 On the inner wall of each semi-circular shell, a heat-insulating cotton 26 is pasted. The heat-insulating cotton 26 is opposite to the part of the spiral groove 211 of the fixed column 21, and an aluminum foil is pasted on the surface of the heat-insulating cotton 26 opposite to the spiral groove 211.

[0054] Combined with Figure 2 and Figure 3 , the output ends of the first infusion tube 40 and the second infusion tube 50 are connected to a three-way tube 80. The output end of the three-way tube 80 is connected to a drip tube 90. There is a drip chamber and a flow regulator on the drip tube 90. One end of the drip tube 90 far from the three-way tube 80 is connected to an infusion needle.

[0055] Taking the example of a patient receiving two infusion bags, at the beginning of the infusion, ensure that only one of the infusion bags is in the infusion state. For example, the first infusion bag 60 is in the infusion state. At this time, the second infusion bag 70 is in a non-infusion state, that is, the first infusion tube 40 connected to the first infusion bag 60 is not pressed by the pressing strip 24, while the second infusion tube 50 connected to the second infusion bag 70 is flattened by the third pressing strip 243 to a non-flow state, that is Figure 11 state.

[0056] When the infusion monitoring module monitors that only the remaining amount of the first infusion bag 60 is lower than the warning value set by the controller, a reminder message is sent to the mobile display through the controller. The reminder message is displayed on the mobile display carried by the medical staff, and at the same time, the reminder message can also be broadcast by the mobile display, which is convenient for the medical staff to hear.

[0057] When the infusion monitoring module monitors that only the remaining amount of the first infusion bag 60 is lower than the warning value set by the controller, a warning message is sent to the mobile display through the controller. The warning message is displayed on the mobile display carried by the medical staff, and the warning message can also be broadcast by the mobile display; at the same time, the controller controls the driver 10 to start, and then drives the outer ring to rotate a certain angle through the driving gear 101, so that the flattened section of the first pressing strip 241 presses the first infusion tube 40 to a non-flow state, while the second infusion tube 50 is located between the second pressing strip 242 and the third pressing strip 243. After ensuring that the second infusion tube 50 is in a flowable state, the driver 10 is stopped; this control makes the first infusion tube 40 blocked after the first infusion bag 60 is finished, and the infusion work of the second infusion bag 70 is started, that is Figure 12 state.

[0058] When the remaining amount of the first infusion bag 60 monitored by the infusion monitoring module is lower than the warning value set by the controller, and the remaining amount of the second infusion bag 70 is lower than the pre-warning value set by the controller, the controller sends an alarm message to the mobile display. The alarm message is displayed on the mobile display carried by the medical staff, and the alarm message can also be broadcast by the mobile display. At the same time, the controller controls the driver 10 to start again, and then drives the outer ring to rotate a certain angle through the driving gear 101, so that the pre-pressing section of the second pressing strip 242 presses on the second infusion tube 50, while the flattened section of the first pressing strip 241 continues to tightly press on the first infusion tube 40, and then the driver 10 is stopped. This control causes the second infusion bag 70 to automatically reduce the flow cross-section of the second infusion tube 50 when the remaining amount is small, thereby increasing the difficulty of the liquid droplets falling, achieving the purpose of reducing the infusion speed of the second infusion tube 50, and reserving more time for the medical staff to reach the patient's side, that is Figure 13 status.

[0059] If the medical staff cannot reach the patient's side in time, the remaining amount of the second infusion bag 70 will continue to decrease. When the infusion monitoring module monitors that the remaining amounts of both infusion bags are lower than the warning value set by the controller, the controller sends an alarm message to the mobile display. The alarm message is displayed on the mobile display carried by the medical staff, and the alarm message is broadcast by the mobile display. At the same time, the controller controls the driver 10 to continue to start until the flattened section of the second pressing strip 242 completely presses on the second infusion tube 50, and at the same time, the first pressing strip 241 still tightly presses on the first infusion tube 40 due to its longer length, ensuring that both the first infusion tube 40 and the second infusion tube 50 are completely flattened to a non-flow state, that is Figure 14 status. In this state, since the infusion tubes are not connected and infusion cannot continue, but it also ensures that air will not enter the patient's body.

[0060] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
