Description

Technical Field

[0001] The present invention relates to the field of medical technology, in particular to an intelligent infusion monitor. Background Art

[0002] Infusion racks are mainly used to hang infusion bottles. At present, the infusion racks used in the medical field only have the simple function of hanging infusion bottles, and the infusion area is planned in the hospital. When the patient is receiving an infusion, since the infusion time is generally more than an hour, the patient is prone to dozing off during the infusion time, and it is easy to miss the best time to change the fluid or remove the needle, which in turn causes air to enter the infusion tube. At the same time, during the infusion, the patient sometimes goes against the doctor's and nurses' instructions and privately adjusts the flow regulator on the infusion tube to the maximum in order to reduce the infusion time. Some drugs in infusion bottles have different safe infusion speeds, which are prone to safety accidents when there is no accompanying care.

[0003] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide an intelligent infusion monitor.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: the intelligent infusion monitor includes a first connecting block and a second connecting block that are interlocked with each other, a receiving cavity is arranged between the first connecting block and the second connecting block, and the inner wall of the receiving cavity is provided with a through hole that penetrates up and down, a plurality of infrared emitters are fixedly connected to the side wall of the receiving cavity, and a photoelectric sensing board that receives infrared rays emitted by the infrared transmitter is fixedly connected to the position of the inner wall of the receiving cavity relative to the infrared transmitter, a control device and an extrusion block are also arranged in the first connecting block, the control device drives the extrusion block to move in the horizontal direction, a controller is also arranged in the first connecting block, the controller includes a signal processing module, a signal transmission module, and a power control module, the signal processing module receives the signal of the number of infrared flashes on the photoelectric sensing board and transmits it to the external hospital monitoring system through the signal transmission module, the signal transmission module receives the signal of the external hospital monitoring system and controls the output power of the control device through the filtering control module, and a power supply connected to the controller is arranged on the second connecting block.

[0006] By adopting the above technical solution, when the intravenous drip pot is located in the accommodating cavity and infusion is given to others, the infrared emitter is used to capture infrared rays toward the photoelectric sensing board in the horizontal direction. When the liquid in the intravenous drip pot drips, the dripping droplets are in the shape of elliptical water drops, causing the infrared rays of the infrared emitter passing through the droplets to deviate from the photoelectric sensing board. At this time, the light intensity received on the photoelectric sensing board is reduced, and the photoelectric sensing board transmits the changed signal to the controller. The controller records the frequency of the signal change and transmits it to the external hospital monitoring system, so that nurses can centrally view the infusion signals of different patients and associate the controller models used by different patients with the doctor's orders. When the infusion speed is too fast, Or when the speed is too slow, the nurse can discover it in time and make adjustments. When the infusion speed needs to be adjusted remotely, the infusion speed is increased or decreased remotely through the hospital monitoring system. Specifically, a signal is transmitted to the controller remotely, and the controller controls the power transmitted by the power supply to the electric motor, and uses its torque to apply different pressures to the infusion tube. When the infusion tube is subjected to a large pressure, the infusion tube made of plastic is squeezed, and the channel for liquid flow in the infusion tube is reduced, thereby reducing the infusion speed. Otherwise, the infusion speed is increased. The electric motor starts to drive the threaded shaft to rotate, and the threaded shaft is threadedly connected to the sliding sleeve and drives the sliding sleeve to move in the horizontal direction, thereby controlling the pressure applied to the infusion tube by the extrusion block.

[0007] The present invention is further configured as follows: a signal light connected to a controller is fixedly connected to the first connecting block. When the photoelectric sensor board does not change for more than ten seconds, the controller not only provides an alarm signal to the hospital monitoring system, but also controls the power supply to transmit power to the signal light and controls the signal light to flash.

[0008] By adopting the above technical solution, when the liquid droplets do not continue to drip downward within ten seconds, that is, when the photoelectric sensor plate does not change within ten seconds, the controller not only provides an alarm signal to the hospital monitoring system to urge the nurse to check the specific situation and change the liquid, but also controls the power supply and transmits power to the signal light, so that the signal light flashes and reminds the patient and the nurse. The nurse determines the specific location of the patient by the flashing light.

[0009] The present invention is further configured as follows: the control device includes an electric motor electrically connected to the controller, a connecting cavity for accommodating the electric motor is provided on the side wall of the first connecting block, a sliding hole connected to the through hole is provided on the inner wall of the connecting cavity, the electric motor output shaft is fixedly connected to a threaded shaft extending into the sliding hole, a sliding sleeve threadedly connected to the threaded shaft is slidably connected in the sliding hole, a protrusion is fixedly connected to the side wall of the sliding sleeve, a limiting groove for accommodating the protrusion is also provided on the inner wall of the sliding hole, and one end of the sliding sleeve close to the through hole is fixedly connected to the extrusion block.

[0010] By adopting the above technical solution, a controller is used to control the power transmitted from the power supply to the electric motor, thereby controlling the torque of the rotation of the output shaft of the electric motor. The output shaft of the electric motor drives the threaded shaft to rotate. The threaded shaft is threadedly connected to the sliding sleeve and drives the sliding sleeve to move into the through hole. The sliding sleeve drives the extrusion block to squeeze the infusion tube, thereby reducing the liquid connection cross-section of the infusion tube, thereby reducing the infusion speed. When the output shaft of the electric motor moves in the opposite direction, the elastic force of the infusion tube itself is used to restore it to the initial state, thereby increasing the infusion speed. The sliding block is slidably connected to the limit groove to limit the rotation of the sliding sleeve, thereby enabling the sliding sleeve to move in a straight line.

[0011] The present invention is further configured as follows: a plurality of corresponding power connection blocks are provided at one end of the first connection block and the second connection block close to each other, and the power connection blocks electrically connect the power supply and the controller through wires.

[0012] By adopting the above technical solution, when the first connecting block and the second connecting block are abutted against each other, the power connection block is used to complete the electrical connection between the power supply and the controller, so that the weight of each component is distributed on the first connecting block and the second connecting block.

[0013] The present invention is further configured as follows: a plurality of connecting blocks are fixedly connected to one end of the first connecting block close to the second connecting block, an end of the connecting block away from the first connecting block is bent outward, a plurality of grooves are provided on the outward bent surface of the connecting block, a connecting hole for the connecting block to pass through is penetrated on the second connecting block, and the connecting block is elastic in the direction of its bending.

[0014] By adopting the above technical solution, the intravenous drip pot is first placed between the separated first connecting block and the second connecting block, and then the two connecting blocks are pressed toward the middle, and the distance between the two connecting blocks is made the same as the distance between the two connecting holes, and then the connecting block is inserted into the connecting hole. When the bending position of the connecting block passes through the other end of the connecting hole, the connecting block is acted upon by its own elastic force and the bending position of the connecting block moves outward. At this time, the groove at the bending position of the connecting block is engaged with the side wall at the opening of the connecting hole, thereby completing the connection between the first connecting block and the second connecting block, and then completing the connection between the present invention and the infusion tube.

[0015] The present invention is further configured as follows: a track groove is provided on the inner wall of the through hole, and the track groove includes a second track groove provided on the first connecting block and a first track groove provided on the second connecting block.

[0016] By adopting the above technical solution, the extrusion block is limited by the track groove, so that the extrusion block is found vertically along the infusion tube to extrude the infusion tube, thereby increasing the effect of controlling the infusion speed.

[0017] In summary, the present invention has the following beneficial effects: The photoelectric sensor board is used to receive light signals, and the frequency of light signal changes on the photoelectric sensor board is monitored to determine the frequency of droplets falling, and then detect the infusion speed. When the infusion speed is too fast, a larger amount of electricity is transmitted to the electric motor through the controller, thereby increasing the pressure applied to the infusion tube by the sliding sleeve and the extrusion block driven by the electric motor, thereby controlling the patient's infusion speed. At the same time, the infusion speed of multiple patients can be monitored online in real time, which not only reduces the workload of nurses but also prevents safety accidents.

[0020] The present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0021] The intelligent infusion monitor, such as Figures 1 to 6As shown, it includes a first connecting block 11 and a second connecting block 12 that are interlocked, an accommodating cavity 13 is arranged between the first connecting block 11 and the second connecting block 12, and the inner wall of the accommodating cavity 13 is provided with a through hole 17 that penetrates up and down, a first accommodating groove 15 is provided in the side wall of the accommodating cavity 13, a plurality of infrared emitters 14 are fixedly connected in the first accommodating groove 15, a second accommodating groove 20 is provided in the inner wall of the accommodating cavity 13 at a position opposite to the infrared emitter 14, a photoelectric sensor plate 19 that receives infrared rays emitted by the infrared emitter 14 is fixedly connected in the second accommodating groove 20, a control device and an extrusion block 22 are further arranged in the first connecting block 11, the control device drives the extrusion block 22 to move in the horizontal direction, and the first connecting block A controller 18 is also provided in the 11, and the controller 18 includes a signal processing module, a signal transmission module, and a power control module. The signal processing module receives the signal of the number of infrared flashes on the photoelectric sensor board 19 and transmits it to the external hospital monitoring system through the signal transmission module. The signal transmission module receives the signal of the external hospital monitoring system and controls the output power of the control device through the filtering control module. The second connecting block 12 is provided with a power supply 29 connected to the controller 18. The first connecting block 11 is fixedly connected with a signal light 16 connected to the controller 18. When the photoelectric sensor board 19 does not change for more than ten seconds, the controller 18 not only provides an alarm signal to the hospital monitoring system, but also the controller 1 8 The control power supply 29 transmits power to the signal light 16 and controls the signal light 16 to flash. The control device includes an electric motor 25 electrically connected to the controller 18. The side wall of the first connecting block 11 is provided with a connecting cavity 26 for accommodating the electric motor 25. The inner wall of the connecting cavity 26 is provided with a sliding hole 27 connected with the through hole 17. The output shaft of the electric motor 25 is fixedly connected with a threaded shaft 24 extending into the sliding hole 27. The sliding hole 27 is slidably connected with a sliding sleeve 23 threadedly connected with the threaded shaft 24. The side wall of the sliding sleeve 23 is fixedly connected with a protrusion. The inner wall of the sliding hole 27 is also provided with a limiting groove 28 for accommodating the protrusion. One end of the sliding sleeve 23 close to the through hole 17 is fixedly connected to the extrusion block 22. The first connecting block 1 1 and the second connection block 12 are provided with a plurality of corresponding power connection blocks 34 at one end close to each other, and the power connection block 34 electrically connects the power supply 29 and the controller 18 through a wire, and a plurality of connection blocks 30 are fixedly connected to one end of the first connection block 11 close to the second connection block 12, and the end of the connection block 30 away from the first connection block 11 is bent outward, and a plurality of grooves are provided on the surface of the connection block 30 bent outward, and a connection hole 31 for the connection block 30 to pass through is penetrated on the second connection block 12, and the connection block 30 has elasticity in the direction of its bending, and a track groove is provided on the inner wall of the through hole 17, and the track groove includes a second track groove 32 provided on the first connection block 11 and a first track groove 21 provided on the second connection block 12.

[0022] A label is engraved on the surface of the first connection block 11 or the second connection block 12, and the label is the same as the model of the hospital monitoring system corresponding to the controller 18. Then, the intravenous drip pot is placed between the two first connection blocks 11 and the second connection blocks 12, that is, the intravenous drip pot is prevented from being in the accommodating cavity 13. Then, one hand makes the ends of the two connection blocks 30 close to each other, and the connection blocks 30 can be inserted into the connection holes 31. When the ends of the connection blocks 30 are inserted into the connection holes 31, the force pressing the connection blocks 30 is released, and the first connection blocks 11 and the second connection blocks 12 are manually pushed close to each other, so that the ends of the first connection blocks 11 and the second connection blocks 12 that are close to each other abut against each other, that is, the power connection blocks 34 on the first connection blocks 11 and the second connection blocks 12 abut against each other, and the first connection blocks 11 and the second connection blocks 12 are completed. The power supply 29 on the second connection block 12 is electrically connected to the controller 18 on the first connection block 11. When the first connection block 11 and the second connection block 12 are in contact with each other, the end of the connection block 30 passes through the connection hole 31 and extends from the other opening thereof. At this time, the connection block 30 is affected by its own elastic force to move the end of the connection block 30 outward, that is, the groove at the bending position of the connection block 30 is engaged with the inner wall of the opening of the connection hole 31, and then the first connection block 11 and the second connection block 12 are connected as a whole by using the connection block 30. When the first connection block 11 and the second connection block 12 need to be separated, the connecting block 30 is pressed by hand at the protruding part, and then the first connection block 11 and the second connection block 12 are separated, thereby completing the detachable connection of the first connection block 11 and the second connection block 12; Then, the infrared emitter 14 is used to emit light along the direction perpendicular to the side wall of the accommodating cavity 13 onto the photoelectric sensing board 19. When the liquid droplets in the intravenous drip pot drip downward, the water droplets change the refractive index of the light between the infrared emitter 14 and the photoelectric sensing board 19, resulting in the weakening of the photoelectric effect at the fixed point position on the photoelectric sensing board 19, that is, the electrical signal of the photoelectric sensing board 19 changes, and the controller 18 records the frequency of the light signal change. The controller 18 then transmits the frequency signal to the hospital monitoring system, and then displays the infusion speed of the patient on the head nurse's screen. At the same time, the actual number of drops of infusion can be detected, and then the amount of liquid medicine left in the infusion bottle can be determined, and the estimated infusion time can be determined, giving the patient and the nurse an accurate time for changing the liquid or removing the needle, thereby reducing the patient's anxiety while waiting. The photoelectric sensing board 19 is provided with a plurality of photoelectric sensors opposite to the infrared emitter 14. When the light emitted by the infrared emitter 14 is refracted, the light intensity irradiated on the photoelectric sensor is reduced, thereby changing the electrical signal transmitted from the photoelectric sensing board 19 to the controller 18; When the nurse sees that the patient's infusion speed is too fast or too slow through the display screen on the hospital monitoring system, a signal is transmitted to the controller 18 and the voltage and current output by the control box electric motor 25 are controlled, thereby controlling the output torque of the electric motor 25. The output shaft of the electric motor 25 drives the threaded shaft 24 to rotate, and the threaded shaft 24 is threadedly connected with the sliding sleeve 23 and drives the sliding sleeve 23 to move, wherein the sliding block 33 is slidably connected with the limiting groove 28 and limits the rotation of the sliding sleeve 23, thereby causing the sliding sleeve 23 to drive the squeezing block 22 to move closer to or away from the infusion tube, thereby reducing or increasing the cross-sectional area of ​​the liquid flow channel in the infusion tube, thereby controlling the infusion speed; When the water in the intravenous drip pot does not drip for more than ten seconds, the display screen in the nurse station displays a stop infusion signal, and the hospital monitoring system transmits a signal to the controller 18 and controls the signal light 16 to flash, wherein the power source of the signal light 16 is the power supply 29; The controller 18 includes a signal processing module, a signal transmission module, and a power control module. The signal processing module receives the signal transmitted by the photoelectric sensor board 19. The signal transmission module and the signal processing module are digital signal processors, which mainly extract the frequency of the received signal change. The signal transmission module mainly adopts Bluetooth, Wi-Fi, LTE and other wireless signal transmission methods to transmit the signal between the present invention and the hospital monitoring system. At the same time, the signal transmission module is also electrically connected to the signal light 16 and the power control module through wires. The power control module is electrically connected to the power supply 29. The power control module adopts a single-chip microcomputer to control the output voltage and current.
