[0002] Infusion therapy, as an indispensable part of the modern medical system, is widely used in the clinical treatment of various diseases. In this process, accurately controlling the infusion rate is crucial because it directly relates to the treatment effect and safety of patients. Traditionally, medical staff mainly rely on visual observation and personal experience to evaluate and adjust the infusion drip rate, but this approach has many uncertainties. The physical differences of patients, the severity of their conditions, and different treatment requirements all demand personalized adjustment of the infusion rate. However, in actual operation, due to the lack of precise monitoring means, adverse reactions such as increased heart rate in patients caused by too fast infusion rate often occur.

[0003] Although there are already some devices on the market for monitoring the infusion drip rate, most of them are designed to be clipped on the drip chamber of the infusion tube. The softness of the drip chamber makes these devices likely to deform when slightly squeezed, thus affecting the accuracy of the monitoring results. In addition, during the infusion process, patients often need to monitor physiological indicators such as heart rate and blood oxygen, which requires wearing or using other devices additionally, undoubtedly increasing the discomfort of patients and the complexity of operation. Summary of the Invention

[0004] The present invention aims to provide a multifunctional infusion monitor to solve the problems of the existing ones, which can only monitor the drip rate with a single function and is likely to cause deformation of the drip chamber during use.

[0005] To achieve the above object, the present invention provides the following technical solution: A multifunctional infusion monitor includes a control system and a box body. The box body includes a functional part and a clamping part. The clamping part includes a first clip and a second clip connected in series. A rotating shaft is provided at the middle connection in series of the first clip and the second clip. A torsion spring is sleeved outside the rotating shaft, and the two spring feet of the torsion spring are respectively abutted against the first clip and the second clip.

[0006] The functional part includes a pair of symmetrically arranged concave-shaped shells.

Both the upper and lower ends of the storage groove are provided with second moving grooves. A second slider is slidably connected to the second moving groove. A second compression spring is arranged between the second slider and the second moving groove. A pair of rotating blocks are fixedly connected inside the shell. The rod body of the connecting rod passes through the middle of the pair of rotating blocks. The rotating shaft is fixedly connected inside the shell. A through hole matching the connecting rod is opened at the top end of the side wall of the second slider. The free end of the connecting rod is placed inside the through hole. An extrusion block is arranged in the storage groove. A spring telescopic rod is fixedly connected to the bottom end of the extrusion block. Fixing grooves matching the second slider are opened at both the upper and lower ends of the extrusion block. A heart rate and blood oxygen sensor is arranged inside the extrusion block.

[0012] The principle and beneficial effects of this technical solution:

[0013] This monitor consists of a control system and a box body. The box body is divided into a functional part and a clamping part. The functional part includes a pair of symmetric concave-shaped shells, and components such as a storage groove, a sliding groove, a moving rod, a slider, a connecting rod, and an extrusion block are arranged inside; the clamping part is composed of a first clip and a second clip, and the clamping function is realized through a rotating shaft and a torsion spring.

[0020] The following further elaborates on the present invention in conjunction with the drawings and embodiments:

[0021] As Figures 1-4 shown, a multifunctional infusion monitor includes a control system and a box body. The control system includes a control module, a blood oxygen and heart rate monitoring module, a drip rate monitoring module, and a power supply module. The blood oxygen and heart rate monitoring module, the drip rate monitoring module, and the power supply module are respectively connected to the control module.

[0022] The box body includes a functional part and a clamping part. The clamping part includes a first clip 1 and a second clip 2 connected in series. A rotating shaft 3 is provided at the middle connection of the first clip 1 and the second clip 2. A torsion spring is sleeved outside the rotating shaft 3, and the two spring feet of the torsion spring are respectively abutted against the first clip 1 and the second clip 2 to achieve a stable clamping function.

[0023] The functional part is composed of a pair of symmetric concave-shaped shells 4. The right ends of each shell are respectively fixedly connected to the closed ends of the first clip 1 and the second clip 2. A storage groove 5 is provided inside the shell for placing the drip chamber of the infusion tube. Sliding grooves 6 are opened at the upper and lower ends of the storage groove 5, and a moving rod 7 is slidably connected in the sliding grooves 6. Pulling springs 8 are fixedly connected between the two side walls of the moving rod 7 and the sliding grooves 6. In the natural state, the pulling spring 8 pushes the moving rod 7 to the outside so that it can hook the top of the drip chamber. When the drip rate is monitored, the drip chamber is placed in the storage groove 5, and the moving rod 7 remains stable under the action of gravity, ensuring the fixation of the device and avoiding affecting the drip chamber at the same time.

[0024] At the top of the extrusion block 18, an infrared transmitting tube 22 and an infrared receiving tube 23 are respectively installed. The drip rate monitoring module can monitor the drip rate of the liquid medicine in real time through the infrared transmitting tube 22 and the infrared receiving tube 23, and the drip rate information will be reflected on the display, enabling medical staff to intuitively judge whether it is necessary to adjust the drip rate. In addition, when the drip rate monitoring module monitors that there is no liquid dripping above in the drip chamber of the infusion tube, that is, when the liquid in the infusion bottle has dripped out, the core control module will trigger the connected buzzer device to send out an alarm message to remind the medical staff to stop the infusion or replenish the liquid in time, thus ensuring the safety and effectiveness of the infusion process.

[0025] A first moving groove 9 is provided at the bottom end of the sliding groove 6, and a first slider 10 is slidably connected therein. A first compression spring 11 is installed between the first slider 10 and the first moving groove 9 for providing elastic support. Second moving grooves 12 are respectively opened at the upper and lower ends of the storage groove 5, and a second slider 13 is slidably connected in the second moving grooves 12. A second compression spring 14 is also provided between the second slider 13 and the second moving grooves 12 to ensure its stable movement in the groove. A pair of rotating blocks 16 are fixedly connected inside the shell. The rod body of the connecting rod 15 passes through the middle of the pair of rotating blocks 16, and a through hole 17 matching the connecting rod 15 is provided at the top end of the side wall of the second slider 13. The free end of the connecting rod 15 is inserted into the through hole 17 to realize the connection between the two.

[0026] Inside the storage groove 5, an extrusion block 18 is provided, and a spring telescopic rod 19 is fixedly connected to its bottom end for providing elastic support. Fixing grooves 20 matching the second slider 13 are respectively opened at the upper and lower ends of the extrusion block 18 to ensure that its position can be stably adjusted when the second slider 13 moves. A heart rate and blood oxygen sensor 21 is embedded inside the extrusion block 18 for monitoring the patient's heart rate and blood oxygen level.

[0027] When blood oxygen and heart rate monitoring is required, medical staff can remove the device and directly clip it onto the patient's finger. At this time, the patient's finger will push the moving rod 7 to move, thereby driving the movement of slider one 10 and slider two 13. When slider two 13 is moved out of the fixed slot 20, the extrusion block 18 is pushed forward under the action of the spring telescopic rod 19, making the blood oxygen sensor closely contact the patient's finger. The heart rate monitoring module collects heart rate and blood oxygen data through the heart rate and blood oxygen sensor 21. If the heart rate monitoring module detects that the patient's heart rate exceeds the set safe range, that is, lower than the lowest set value or higher than the highest set value, the core control module will send an alarm message to remind medical staff to take timely measures, such as stopping the infusion or adjusting the drip rate, to ensure the safety of the patient and the effectiveness of the treatment.

[0028] After completing the blood oxygen and heart rate monitoring, medical staff can push the extrusion block 18 backward to make it return to the fixed slot 20, and can switch back to the drip rate monitoring mode. Inductive buttons or sensors are respectively installed below slider one 10 and above slider two 13. When the moving rod 7 drives slider one 10 to move, the sensor will detect this action and transmit the signal to the control module. After receiving the signal, the control module will start the heart rate monitoring module and push the extrusion block 18 back to its original position. At this time, slider two 13 will also move and transmit the signal to the control module to make it start the drip rate monitoring module to continue monitoring the infusion drip rate.

[0029] Ensure that the moving rod 7 will not be blocked by slider one 10 during the movement. Rounded corners are designed at the top of slider one 10 and the bottom of slider two 13. Among them, the rounded corner at the bottom of slider two 13 is smaller. The rounded corner is to ensure that when slider two 13 moves insufficiently, the extrusion block 18 can be pushed out by the force generated by the spring telescopic rod 19 and will not be blocked by slider two 13. And the smaller rounded corner ensures that when slider two 13 is used to fix the extrusion block 18, it can be in full contact with the moving slot two 12 to ensure firmness. In addition, a window 24 is opened at the left end of the housing, which is convenient for medical staff to directly observe the situation inside the drip chamber with the naked eye, so as to timely discover and handle possible problems.

[0030] A display screen is also provided at the front end of the housing, which can clearly display the blood oxygen and heart rate conditions as well as the drip rate conditions, enabling medical staff to grasp the patient's physiological indicators and infusion status in real time. To improve the comfort of the patient during use, a rubber pad is fixedly connected to the outside of the extrusion block 18, so that the discomfort can be reduced when squeezing the finger, ensuring a comfortable experience for the patient during the monitoring process.

[0031] The power module is used to supply power to the core control module. The power module is preferably a rechargeable battery, which is convenient to use.

[0032] The above are only embodiments of the present invention, and common general technical solutions or characteristics in the solution are not described in detail herein. For those skilled in the art, without departing from the technical solution of the present invention, several modifications 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 practicability of the patent.
