Description

Technical Field

[0001] The present invention relates to the technical field of infusion auxiliary tools, and in particular to a intravenous infusion monitoring and alarm device. Background Art

[0002] Intravenous infusion is a commonly used treatment method in clinical practice. During the infusion process, the patient or the patient's family members need to manually monitor the infusion situation. When the liquid in the medicine bottle is used up, the patient or the patient's family members call the medical staff to replace the liquid or remove the needle for the patient. However, when the infusion is manually monitored, the following situations are likely to occur: (1) The liquid in the medicine bottle drips out without being discovered, and air enters the infusion tube. Exhausting air to the upper end of the infusion tube increases the workload of medical staff, and exhausting air to the lower end of the infusion tube is likely to cause waste of liquid medicine; (2) The liquid in the infusion bottle drips out for too long, the pressure is insufficient, and the intravenous indwelling needle or disposable intravenous infusion needle connected to the blood vessel is easily blocked by blood return. The need to remove the needle and puncture again increases the patient's pain, financial burden, and workload of the nurse; (3) the liquid in the infusion bottle is emptied for too long, and the venous blood flows back to the venous indwelling needle or disposable intravenous infusion needle for a long time. When the nurse tries to withdraw or squeeze or flush the tube with a little pressure, there is a risk of thrombus detachment or migration in the blood vessels; (4) the liquid in the bottle has not been infused, and the patient or the patient's family presses the bell in advance. When the nurse arrives at the patient's bedside, there is basically no time to wait for the liquid to completely drain the infusion bottle, and the infusion bottle is replaced directly, which causes a certain degree of waste of liquid medicine; (5) The patient or the caregiver will need to pay attention to the infusion situation, which directly affects their personal rest and sleep. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an intravenous infusion monitoring and alarm device, which is used to replace manual monitoring of the infusion situation, and can control the bedside call bell to alarm immediately after the liquid in the infusion bottle drips out, so as to remind medical staff to remove the needle or change the medicine bottle in time.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A intravenous infusion monitoring alarm device comprises a bedside call bell arranged at a nurse station; its distinguishing feature is that the intravenous infusion monitoring alarm device also comprises a first shell, a second shell, a detection unit, a flow regulating device, a single-chip computer module and a power supply module; wherein the first shell is a square structure with an open upper end, a first partition plate is arranged inside the first shell along its width direction, a first tube groove is arranged at a portion where the bottom surface of the first shell overlaps with the first partition plate, and the first tube groove is used to clamp the infusion tube on the pipeline above the Murphy-type dropper; the second shell is a directional structure with an open upper end, a second partition plate is arranged inside the second shell along its width direction, a second tube groove is arranged at a portion where the bottom surface of the second shell overlaps with the second partition plate, and the second tube groove is used to clamp the infusion tube on the pipeline above the Murphy-type dropper; The device is clamped on the pipeline between the Murphy-type dropper and the infusion regulator of the infusion tube; the detection unit is arranged on the groove wall of the first tube groove, and is used to detect whether there is liquid flowing through the infusion tube; the flow regulating device is arranged in the second shell, and the side wall of the second partition plate is provided with a side hole connected with the second tube groove, and the flow regulating device is arranged beside the side hole, and is used to adjust the liquid flow in the infusion tube; the single-chip computer module is arranged in the second shell, and is electrically connected with the bedside call bell, the detection unit and the flow regulating device respectively. When the detection unit detects that no liquid passes through, it sends a feedback signal to the single-chip computer module, and the single-chip computer module controls the alarm of the bedside call bell and controls the operation of the flow regulating device according to the feedback signal; the power supply module is used to provide working voltage.

[0006] The beneficial effects of the present invention are:

[0007] The present invention provides an intravenous infusion monitoring and alarm device. When in use, the pipeline of the infusion tube located above the Murphy-type dropper is clamped on the first tube groove of the first shell, and the pipeline of the infusion tube located between the Murphy-type dropper and the infusion regulator is clamped on the second tube groove of the second shell. When the liquid in the infusion bottle is completely infused, the detection unit will detect that no liquid has passed through, and send a feedback signal that no liquid has been detected to the single-chip microcomputer module. The single-chip microcomputer module controls the bedside call bell to sound an alarm according to the feedback signal to remind the medical staff at the nurse station that the patient's medicine has been completely infused, so as to replace the medicine bottle or remove the needle in time; at the same time, the single-chip microcomputer module will control the flow regulating device to work, and reduce the flow of the infusion tube to avoid the rapid infusion of the remaining liquid in the infusion tube, thereby avoiding the problem of blood return; therefore, the intravenous infusion monitoring and alarm device can replace manual monitoring of the infusion situation, reduce the workload of medical staff, and at the same time improve the safety of infusion and the utilization rate of the medicine.

DETAILED DESCRIPTION

[0018] The present invention is described below in conjunction with the accompanying drawings. The specific implementation methods described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solution of the present invention by ordinary technicians in this field should fall within the protection scope of the present invention.

[0019] like Figures 1 to 9 As shown, the intravenous infusion monitoring alarm device of this embodiment includes a bedside call bell 1, a first shell 2, a second shell 3, a detection unit 4, a flow regulating device 5, a single chip module 6 and a power supply module 7.

[0020] Among them, the bedside call bell 1 is set at the nurse station.

[0021] The first shell 2 is a square structure with an open upper end. A first partition plate 21 is arranged inside the first shell 2 along its width direction. A first tube groove 22 is arranged at the portion where the bottom surface of the first shell 2 overlaps with the first partition plate 21. The first tube groove 22 is used to clamp the infusion tube on the pipeline above the Murphy's dropper. The first tube groove 22 is recessed in the thickness direction of the first partition plate 21, and both ends of the first tube groove 22 pass through both ends of the first shell 2.

[0022] The second shell 3 is an open structure at the upper end, and a second partition plate 31 is arranged inside the second shell 3 along its width direction. A second tube groove 32 is arranged at the portion where the bottom surface of the second shell 3 overlaps with the second partition plate 31. The second tube groove 32 is used to clamp the infusion tube on the pipeline between the Murphy's dropper and the infusion regulator. The second tube groove 32 is recessed in the thickness direction of the second partition plate 31, and both ends of the second tube groove 32 pass through both ends of the second shell 3.

[0023] The detection unit 4 is arranged on the groove wall of the first tube groove 22, and is used to detect whether there is liquid flowing through the infusion tube. The detection unit 4 of this embodiment is an infrared photoelectric liquid level sensor, whose transmitting end is arranged on one side of the first tube groove 22, and the other end is arranged on the other side of the first tube groove 22. The infrared photoelectric liquid level sensor is a common sensor in life, and its detection principle is: its core components are an infrared transmitting tube (transmitting end) and a photosensitive receiver (receiving end). This sensor uses the characteristics of infrared rays and can be used to detect the presence or absence of liquid. When the infusion tube is in a state without liquid, the infrared rays emitted by the infrared transmitting tube can directly irradiate the receiving tube after passing through the infusion tube, and the receiving tube will generate a corresponding electrical signal after receiving the light; when the infusion tube is in a state with liquid, the light is refracted by the liquid and cannot directly irradiate the receiving tube, resulting in the receiving tube being unable to receive light or only receiving a small amount of light. At this time, the electrical signal output by the receiving tube is weakened or disappears; thus, the sensor can determine whether there is liquid or not.

[0024] The flow regulating device 5 is arranged in the second shell 3. The side wall of the second partition plate 31 is provided with a side hole 311 connected to the second tube groove 32. The flow regulating device 5 is arranged beside the side hole 311 to adjust the liquid flow in the infusion tube.

[0025] The single-chip computer module 6 is arranged in the second shell 3, and is electrically connected to the bedside call bell 1, the detection unit 4 and the flow regulating device 5 respectively. When the detection unit 4 detects that no liquid passes through, it sends a feedback signal to the single-chip computer module 6. The single-chip computer module 6 controls the bedside call bell 1 to alarm and controls the flow regulating device 5 to operate according to the feedback signal.

[0026] The flow regulating device 5 of this embodiment includes a stepper motor 51, a screw rod 52, a nut 53, a spring 54, an extrusion block 55, a protrusion 56 and a pressure sensor 57. The stepper motor 51 is arranged beside the second partition plate 31, and the stepper motor 51 is electrically connected to the single-chip computer module 6. The screw rod 52 is arranged parallel to the second partition plate 31, one end of which is connected to the rotating shaft of the stepper motor 51, and the other end is rotatably connected to the side wall of the second housing 3. The nut 53 is installed on the screw rod 52, and after the screw rod 52 rotates, the nut 53 can move on the screw rod 52. The spring 54 is arranged between the screw rod 52 and the side hole 311, one end of the spring 54 is hinged to the plate surface of the second partition plate 31 beside the side hole 311 close to the stepper motor 51, and the other end is arranged obliquely and blocked in front of the side hole 311. The extrusion block 55 is arranged on the surface of the spring 54 close to the side hole 311. The protrusion 56 is arranged on the surface of the nut 53, and is located between the nut 53 and the spring 54. The protrusion 56 is used to press the spring 54 toward one side of the side hole 311 and make the squeezing block 55 squeeze the infusion tube. The pressure sensor 57 is arranged on the groove wall of the second tube groove 32 opposite to the side hole 311, and is electrically connected to the single chip module 6, and is used to detect the pressure applied by the squeezing block 55 to the infusion tube.

[0027] The working principle of the flow regulating device 5 is as follows: in the initial state, the nut 53 is located between the stepping motor 51 and the spring 54, the single-chip module 6 controls the stepping motor 51 to rotate, and the nut 53 moves toward the spring 54 along the length direction of the screw rod 52. When the protrusion 56 contacts the spring 54, the protrusion 56 will continuously press the spring 54 in the direction of the side hole 311, so that the squeezing block 55 on the spring 54 extends into the side hole 311 and squeezes the infusion tube in the second tube groove 32. At this time, the pressure sensor 57 detects the pressure applied by the squeezing block 55 to the infusion tube in real time, and a pressure threshold is set in the single-chip module 6. When the pressure value detected by the pressure sensor 57 exceeds the pressure threshold, the single-chip module 6 controls the stepping motor 51 to stop rotating. Since the infusion tube is squeezed by the squeezing block 55, the liquid flow rate of the current pipeline is reduced, thereby slowing down the flow rate of the liquid in the infusion tube, so that the liquid in the infusion tube will not flow out quickly.

[0028] In addition, the flow regulating device 5 of the present embodiment further includes a spring 58. A fixing block 33 is disposed in the second housing 3. The fixing block 33 is disposed opposite to the end of the spring sheet 54 that is not connected to the second partition plate 31, and the screw rod 52 is located between the spring sheet 54 and the fixing block 33. The two ends of the spring 58 are respectively connected to the surface of the fixing block 33 and the end of the spring sheet 54 that is not connected to the second partition plate 31. When the projection 56 presses down the spring sheet 54, the spring 58 will extend and generate elastic force.

[0029] The opening of the first housing 2 of this embodiment is provided with a first cover 23. The opening of the second housing 3 is provided with a second cover 34, on which a motor reset switch 341 and a bedside call bell switch 342 are provided, and both the motor reset switch 341 and the bedside call bell switch 342 are electrically connected to the single-chip module 6. When the squeezing block 55 squeezes the infusion tube, the motor reset switch 341 is pressed, and the stepping motor 51 rotates in the opposite direction, so that the nut 53 moves along the length direction of the screw rod 52 toward the direction of the stepping motor 51, so that the protrusion 56 gradually separates from the spring 54. At this time, the spring 58 releases the elastic force, so that the spring 54 gradually resets, and the squeezing block 55 also gradually separates from the infusion tube. When the pressure sensor 57 detects that the pressure generated by the squeezing block 55 on the infusion tube is equal to zero or close to zero, the single-chip module 6 controls the stepping motor 51 to stop rotating. In the circuit, the single-chip microcomputer module 6 adopts the STM32F103C7T6 single-chip microcomputer, the stepper motor 51 is represented by M, and the motor reset switch 341 is represented by K1. After the button K1 is pressed, the transistor Q1 is not turned on, and the transistor Q2 is turned on. Correspondingly, the relay KA1 is not turned on, and the relay KA2 is turned on. At this time, the stepper motor 51 conducts electricity in the reverse direction, thereby reversing. It is defined that the nut 53 moves in the direction of the stepper motor 51 at this time. When the pressure sensor 57 detects that the pressure value is equal to zero or close to zero, the single-chip microcomputer module 6 controls the stepper motor 51 to stop rotating; and when the infrared photoelectric liquid level sensor sends a feedback signal to the single-chip microcomputer module 6, the transistor Q1 is turned on, and the transistor Q2 is not turned on. Correspondingly, the relay KA1 is turned on, and the relay KA2 is not turned on. At this time, the stepper motor 51 conducts electricity in the forward direction, thereby rotating forward. It is defined that the nut 53 moves in the direction of the spring 54 at this time. When the pressure sensor 57 detects that the pressure value exceeds the pressure threshold, the single-chip microcomputer module 6 controls the stepper motor 51 to stop rotating.

[0030] In the circuit, the bedside call bell switch 342 is represented by K2. When the infrared photoelectric liquid level sensor sends a feedback signal to the single-chip microcomputer module 6, the single-chip microcomputer module 6 controls the transistor Q5 to be turned on. At this time, the bedside call bell 1 alarms. The bedside call bell 1 of this embodiment is an audible and visual alarm, which can emit both an alarm sound and a flashing light. When the bedside call bell 1 sounds an alarm, the bedside call bell switch 342 is pressed, and the single-chip microcomputer module 6 controls the transistor Q5 to be turned off. At this time, the bedside call bell 1 stops alarming. In addition, the bedside call bell switch 342 can independently control the alarm of the bedside call bell 1. When the single-chip microcomputer module 6 outputs a low level to the base of the transistor Q5, the bedside call bell 1 switch is pressed, and the single-chip microcomputer module 6 outputs a high level to the base of the transistor Q5. At this time, the transistor Q5 is turned on, and the bedside call bell 1 issues an alarm; when the single-chip microcomputer module 6 outputs a high level to the base of the transistor Q5, the bedside call bell switch 342 is pressed, and the single-chip microcomputer module 6 outputs a low level to the base of the transistor Q5. At this time, the transistor Q5 is not turned on, and the bedside call bell 1 does not issue an alarm.

[0031] Since the bedside call bell 1 is set at the nurse station and is far away from the ward, the bedside call bell 1 is connected to the single-chip computer module 6 through a wire 8, and the end of the wire 8 has a plug. A socket 35 connected to the plug of the wire 8 is set on the side wall of the second shell 3.

[0032] The power module 7 of this embodiment includes a first power module 71 arranged in the first housing 2 and a second power module 72 arranged in the second housing 3, and the side wall of the first housing 2 is provided with a charging port 8 for charging the first power module 71, the first power module 71 is used to power the infrared photoelectric liquid level sensor, and the surface of the first cover 23 is provided with a power switch 9; the side wall of the second housing 3 is provided with a charging port 8 for charging the second power module 72, the second power module 72 is used to power the single-chip module 6, the pressure sensor 57 and the stepping motor 51, and the surface of the second cover 34 is provided with a power switch 9. The bedside call bell 1 can be powered by the second power module 72, in which case the power line and the data transmission line need to be converged on one wire, or a power supply for powering the bedside call bell 1 can be separately provided at the nurse station.

[0033] In order to improve the stability of the first shell 2 and the second shell 3, a connecting rod 10 is arranged between the lower end of the first shell 2 and the upper end of the second shell 3. The connecting rod 10 is a telescopic rod. The side wall of the connecting rod 10 is provided with a clamp 101. The clamp 101 is used to clamp on the infusion pole. Under the action of the connecting rod 10 and the clamp 101, the first shell 2 and the second shell 3 clamped on the infusion tube are not easy to slip. In addition, since the infrared photoelectric liquid level sensor needs to be electrically connected to the single-chip computer module 6, the connecting rod 10 is arranged as a hollow tube to facilitate the passage of wires.

[0034] When the present invention is used, the pipeline of the infusion tube located above the Murphy's dropper is clamped on the first tube groove 22 of the first shell 2, the pipeline of the infusion tube located between the Murphy's dropper and the infusion regulator is clamped on the second tube groove 32 of the second shell 3, and the plug of the wire 8 of the bedside call bell 1 is inserted into the jack 35 of the second shell 3, so that the bedside call bell 1 is connected to the single-chip module 6, and then the power switches 9 on the two covers are pressed to make each component conductive. When the liquid in the infusion bottle is completely infused, no liquid will flow through the pipeline of the infusion tube clamped by the first tube groove 22. At this time, the infrared photoelectric liquid level sensor will detect that no liquid has passed through, and send a feedback signal that no liquid has been detected to the single-chip module 6. The single-chip module 6 controls the bedside call bell 1 to send an alarm according to the feedback signal to remind the medical staff at the nurse station that the patient's liquid has been infused, so as to replace the medicine bottle or remove the needle in time; at the same time, the single-chip module 6 will control the stepping motor 51 to rotate forward, so that the nut 53 moves in the direction of the spring 54. The convex block 56 on the nut 53 presses down the spring sheet 54 so that the squeezing block 55 extends into the side hole 311 and squeezes the infusion tube in the second tube groove 32. When the pressure value measured by the pressure sensor 57 reaches the set threshold, the single-chip computer module 6 controls the stepper motor 51 to stop rotating. Since the infusion tube is squeezed by the squeezing block 55, the flow rate of the infusion tube will be reduced, so as to avoid the remaining liquid in the infusion tube from being quickly infused, thereby avoiding the problem of blood return; when the medical staff arrives at the ward, they press the bedside call bell switch 342 to stop the bedside call bell 1 from alarming. After that, the medical staff replaces the medicine bottle or removes the needle. After replacing the medicine bottle, the medical staff can press the motor reset switch 341 to make the stepper motor 51 rotate in the opposite direction and move the nut 53 in the direction of the stepper motor 51. The bump 56 is separated from the spring 54, and the spring 54 is reset. When the pressure sensor 57 detects that the pressure value is zero or close to zero, the single-chip module 6 controls the stepper motor 51 to stop rotating. At this time, the infusion tube is not squeezed and can be infused normally. Repeat the above steps.

[0035] In summary, the intravenous infusion monitoring and alarm device can replace manual monitoring of infusion conditions, reduce the workload of medical staff, and at the same time improve the safety of infusion and the utilization rate of liquid medicine.
