Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical infusion technology, and in particular to an infusion drip rate display with calculation function. Background Technology
[0002] In clinical practice, when administering intravenous infusions to special patients, it is often necessary to use an infusion drip rate monitor to monitor the infusion process. This not only helps to improve the safety and quality of treatment, but also optimizes nursing care and promotes doctor-patient cooperation. In addition, a calculation function can be added to the infusion drip rate monitor to calculate the approximate infusion time, thereby facilitating use by both doctors and patients.
[0003] Among them, a search revealed Chinese patent CN222426845U, which discloses a portable infusion drip rate display. The aforementioned patent uses a structure in which the outer shell is attached to the infusion drip tube to fix the infusion drip rate display. However, this method of fixing the outer shell to the infusion drip tube is inconvenient for medical staff to operate, and the outer shell cannot completely cover the drip chamber on the infusion drip tube, allowing external light to easily enter the drip chamber. This causes the photoelectric sensor to easily deviate in monitoring the drip rate inside the drip chamber. Therefore, in order to advance the industry's technology, better facilitate the use of infusion drip rate displays, and improve the core technology competitiveness, this application proposes a new implementation scheme that differs from the structure and application method of infusion drip rate displays in the prior art. Utility Model Content
[0004] The purpose of this invention is to solve the problems of existing infusion drip rate displays being inconvenient to install and prone to errors in droplet detection, and to propose an infusion drip rate display with calculation function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An infusion drip rate display with calculation function includes a front clamp and a rear clamp. A connecting plate is fixedly connected to one side of the front and rear clamps. The two connecting plates are rotatably connected by two rotating shafts. Torsion springs are sleeved at both ends of the rotating shafts between the two connecting plates. A receiving groove is provided on the inner side of the front and rear clamps. A photoelectric sensor is snapped into the inner wall of the receiving groove. A control circuit board is fixedly connected to the inner wall of one side of the front clamp. A display screen is embedded in the outer wall of one side of the front clamp through an opening. Multiple control buttons are embedded in the outer wall of this side of the front clamp through an opening.
[0007] Furthermore, a battery and an alarm bell are fixedly connected to one inner wall of the front housing.
[0008] Furthermore, a micro motor is fixedly connected to one inner wall of the front clamping shell, and a threaded rod is keyed to the output end of the micro motor. A clamping plate is threadedly fitted onto the outer wall of the threaded rod, and a limit arc block is fixedly connected to one side of the clamping plate.
[0009] Furthermore, two guide rods are fixedly inserted into one side of the inner wall of the front clamping shell, and the clamping plate is slidably sleeved with the guide rods.
[0010] Furthermore, the inner wall of the receiving groove is bonded with an anti-slip pad.
[0011] Furthermore, one side of the front clamping shell is provided with multiple sound-permeable holes.
[0012] Furthermore, the connecting plate is provided with an opening, and multiple anti-slip strips are fixedly connected to one side of the connecting plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By using the elastic force of the torsion spring to bring the front and rear clamps together in the middle, the infusion drip rate display can be quickly and conveniently clamped on the outside of the infusion tube, and the drip chamber can be completely enclosed in the receiving groove of the front and rear clamps, thereby preventing external light from entering the drip chamber and avoiding deviation of the photoelectric sensor in monitoring the drip rate inside the drip chamber.
[0015] 2. Driven by a micro motor, the threaded rod rotates, causing the clamping plate to move along the guide rod, which in turn moves the limiting arc block, thereby adjusting the clamping force of the limiting arc block on the dropper, thus tightening the dropper and maintaining a constant dripping speed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-5 An infusion drip rate display with calculation function includes a front clamp 1 and a rear clamp 2. A connecting plate 3 is integrally formed on one side of both the front clamp 1 and the rear clamp 2. The two connecting plates 3 are rotatably connected by two rotating shafts. Torsion springs 4 are sleeved at both ends of the rotating shafts between the two connecting plates 3. Receiving grooves 5 are provided on the inner sides of both the front clamp 1 and the rear clamp 2. Squeezing the connecting plate 3 inward causes the two front clamps 1 and the rear clamp 2 to open outward. Then, the front clamps 1 and the rear clamp 2 are clamped onto the outside of the infusion drip tube, aligning the drip chamber with the receiving groove 5. Releasing the connecting plate 3 causes the front clamps 1 and the rear clamp 2 to converge towards the center under the elastic action of the torsion springs 4, thus quickly and conveniently clamping the infusion drip rate display onto the infusion drip tube. On the outside of the tube, a photoelectric sensor 6 is snapped onto the inner wall of the receiving groove 5. The photoelectric sensor 6 detects the droplets in the dripping pot, with the moment the droplet falls as a detection and the time data is recorded. When the second droplet is detected, the data is recorded again to obtain the drip rate data. A control circuit board 7 is fixed to the inner wall of one side of the front clamping shell 1 by bolts. A processor, model ARM9TDMI, is soldered onto the control circuit board 7. A display screen 9 is embedded in the outer wall of one side of the front clamping shell 1 through an opening. The control circuit board 7 is electrically connected to the display screen, which displays the current flow rate and remaining time. Multiple control buttons 10 are embedded in the outer wall of this side of the front clamping shell 1 through an opening. The control buttons 10 are electrically connected to the control circuit board 7.
[0024] A battery 8 and an alarm bell 11 are fixed to the inner wall of one side of the front clamp 1 by bolts. The battery 8 is electrically connected to the photoelectric sensor 6, the display screen 9, and the micro motor 12. A number of sound-permeable holes 18 are provided on one side of the front clamp 1. When the photoelectric sensor 6 does not detect the droplet, the alarm bell 11 will sound an alarm. The alarm sound is transmitted to the outside through the sound-permeable holes 18 so that the staff can understand the infusion situation.
[0025] A micro motor 12 is bolted to one inner wall of the front clamping shell 1. A threaded rod 13 is keyed to the output end of the micro motor 12. A clamping plate 15 is threaded onto the outer wall of the threaded rod 13. A limiting arc block 16 is bolted to one side of the clamping plate 15. Two guide rods 14 are fixedly inserted into one inner wall of the front clamping shell 1. The clamping plate 15 is slidably sleeved with the guide rods 14. Driven by the micro motor 12, the threaded rod 13 rotates, causing the clamping plate 15 to move along the guide rods 14, thereby driving the limiting arc block 16 to move, thus adjusting the clamping force of the limiting arc block 16 on the dropper, thereby tightening the dropper and keeping the drip rate constant. An anti-slip pad 17 is adhered to the inner wall of the receiving groove 5, thereby increasing the friction between the front clamping shell 1 and the rear clamping shell 2 and the drip chamber, thereby better clamping it on the infusion tube. The connecting plate 3 is provided with a through-hole 19. Multiple anti-slip strips 20 are integrally formed on one side of the connecting plate 3, thereby facilitating the operation of the connecting plate 3.
[0026] The working principle of this embodiment is as follows: When in use, first, pinch the connecting plate 3 inward, so that the two front clamps 1 and the rear clamp 2 open outward. Then, clamp the front clamps 1 and the rear clamp 2 on the outside of the infusion tube and align the drip chamber with the receiving groove 5. Then, release the connecting plate 3. Under the elastic action of the torsion spring 4, the front clamps 1 and the rear clamp 2 converge towards the middle, so that the infusion drip rate display can be clamped on the outside of the infusion tube quickly and conveniently, and the drip chamber is completely wrapped in the receiving groove 5 of the front clamps 1 and the rear clamp 2, thereby preventing external light from entering the drip chamber.
[0027] During infusion, the photoelectric sensor 6 monitors the drip rate and transmits the information to the processor on the control circuit board 7. The current flow rate and remaining time are displayed on the screen 9. As the infusion continues, the liquid level in the infusion bottle decreases, and the drip rate in the dropper changes accordingly. When the photoelectric sensor 6 detects a change in the drip rate, the sensor signal is sent to the control circuit board 7 for analysis and processing. Then, the control circuit board 7 sends a signal to control the micro motor 12 to rotate. Driven by the micro motor 12, the threaded rod 13 rotates, causing the clamping plate 15 to move along the guide rod 14, which in turn moves the limiting arc block 16. This adjusts the clamping force of the limiting arc block 16 on the dropper, thereby tightening the dropper and maintaining a constant drip rate. When the photoelectric sensor 6 does not detect any droplets, the alarm bell 11 sounds an alarm. The alarm sound is transmitted to the outside through the sound hole 18 so that staff can be informed of the infusion situation and facilitate subsequent handling.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
