Technical Field
[0001] The utility model relates to the technical field of infusion control devices, in particular to an infusion control device with a prompting function. Background Art
[0002] Infusion refers to a large dose of injection that is delivered into the body by intravenous drip, usually packaged in glass or plastic infusion bottles or bags, and does not contain antibacterial agents. When used, the drip rate is adjusted through the infusion device to continuously and stably deliver the drug into the body. The main purpose is to replenish blood volume and electrolytes, replenish energy and nutrition, and deliver drugs, etc.
[0003] The infusion control device is a device used in the medical field. It is mainly used to control and adjust the infusion speed to ensure the safety of infusion. It is also the core part of the infusion system and is widely used in operating rooms, ICU wards, emergency rooms and places where patients often need infusion.
[0004] In the "intravenous infusion control device" with the patent CN214633262U, it is mainly composed of an infusion needle, a transparent infusion tube, a red color sensor, an alarm, and an electric forceps, and its characteristics are: the infusion needle is connected to the transparent infusion tube, the red color sensor is arranged on one side of the transparent infusion tube at the connection between the infusion needle and the transparent infusion tube, the red color sensor is connected to the alarm, and the alarm is connected to the electric forceps. When all the liquid medicine in the transparent infusion tube enters the patient's body, blood return will occur, and the red blood will flow back into the transparent infusion tube. At this time, the red color sensor will transmit the signal to the alarm and the electric forceps, thereby causing the alarm to sound, and the electric forceps will clamp the transparent infusion tube to prevent the continued blood return phenomenon, and the medical staff will carry out targeted work;
[0005] When the above-mentioned infusion control device is used with infusion, the flow rate of the infusion is mostly controlled by controlling the flow rate of the liquid medicine in the infusion tube through a roller. However, this flow rate control method may become loose and deviate due to the instability of the roller during later use, which makes it inconvenient for the infusion control device to stably control the infusion flow rate.
[0006] Therefore, we have proposed an infusion control device with a prompting function that can well solve the above problems. Utility Model Content
[0007] The purpose of the utility model is to provide an infusion control device with a prompt function to solve the problem raised by the above-mentioned background technology that most of the infusion flow rate controls in the market currently use rollers to control the flow rate of the medicine in the infusion tube, but this flow rate control method will become loose and offset due to the instability of the roller during later use, which is inconvenient for the infusion control device to stably control the infusion flow rate.
[0008] To achieve the above object, the utility model provides the following technical solution: an infusion control device with a prompting function, comprising an infusion tube, a drip pot is arranged below the infusion tube, and the diameter of the drip pot is larger than the diameter of the infusion tube, and the infusion tube is connected through the top of the infusion tube;
[0009] It also includes: an adjusting seat, whose two ends are grooved and penetrated by a pressing rod for sliding installation, and the two pressing rods are symmetrically arranged about the vertical center line of the adjusting seat, and the outer ends of the two pressing rods extend to the outside of the two ends of the adjusting seat, and the inner ends of the two pressing rods are connected to a clamping plate by screws, and a drip pot, whose internal groove is grooved and penetrated by a slider to install a floating plate for sliding installation, and the floating plate is hollow, and the diameter of the floating plate is smaller than the diameter of the drip pot.
[0010] Preferably, the adjustment seat has grooves at both ends inside and arc blocks are rotatably installed, and the two arc blocks are both arc-shaped, and the outer sides of the two arc blocks are connected in sequence with a row of arc grooves, and the two rows of arc grooves are equally spaced and arranged on the outer sides of the two pressing rods. The adjustment seat has grooves at both ends inside and reset springs are provided, and the two reset springs have the same structure, and the outer ends of the two reset springs are connected to arc blocks, and the two arc blocks can be ejected into the two rows of arc grooves in sequence by the elastic force of the two reset springs themselves, and then the pressing rods can be slidably limited.
[0011] Preferably, the inside of the two arc blocks are grooved with torsion springs, and the inner sides of the two torsion springs are wrapped with rotating shafts, and the outer ends of the two rotating shafts extend through and extend to the outsides of both ends of the adjustment seat. The elastic force of the two torsion springs themselves can be used to elastically reset the positions of the two rotating shafts after rotation, so as to facilitate repeated operations in the future.
[0012] Preferably, the float plate is made of EVA ethylene and vinyl acetate copolymer, and the drip pot is provided with gravity sensors on both sides of its bottom, and the top ends of the two gravity sensors correspond to the two ends of the bottom of the float plate. At the same time, the two gravity sensors are connected to the two alarms through electronic signals and circuits, and the two alarms are symmetrically arranged on both sides of the bottom of the adjustment seat. The decreasing volume of the liquid medicine in the drip pot can be monitored by the two gravity sensors, and then the two alarms will automatically alarm after the infusion is completed.
[0013] Preferably, the floating plate is provided with a sealing seat at the bottom, and the outer side of the sealing seat is sealingly connected to the inner wall of the infusion tube, and the infusion tube can be automatically closed by the sealing seat, thereby preventing air from entering.

[0015] (1) A clamping plate is provided, and an adjustment seat is connected through the outside of the infusion tube, and then a pressing rod is slidably installed through the grooves at both ends of the inner side of the adjustment seat, and the inner sides of the two pressing rods are connected to the outer wall of the infusion tube through anti-skid pads. When the flow rate of the liquid medicine transported inside the infusion tube needs to be controlled later, only the two pressing rods need to be manually pressed to drive the two clamping plates to squeeze and move the infusion tube through the anti-skid pads, so that the flow rate of the liquid medicine transported inside the infusion tube can be controlled by the two clamping plates that squeeze and move, which is more practical;
[0016] (2) Furthermore, by using the slots at both ends of the inner side of the adjustment seat and the arc blocks being rotatably installed by the return spring, when the two pressing rods are pressed to drive the two clamping plates to retract and move, the two return springs will eject the two arc blocks into the two rows of arc grooves in turn through their own elastic force, and then the two pressing rods that are pressed and moved can be slidably limited, thereby avoiding the phenomenon of the two clamping plates being misaligned and offset when controlling the flow rate in the later stage, thereby improving the control stability of the infusion control device;
[0017] (3) Furthermore, by using the grooves in the two arc blocks and rotating the shafts through the torsion springs, when the flow rate of the liquid medicine in the infusion tube needs to be increased later, it is only necessary to manually rotate the two shafts to drive the two arc blocks to separate from the two rows of arc grooves, so that the adjustment seat can be separated from the pressing rod, and then the two clamps can be driven to separate from the infusion tube, which is more time-saving and labor-saving;

The floating plate is slidably installed inside the drip pot. When the infusion tube delivers the liquid medicine, the liquid medicine will drive the floating plate to rise by its own force. When the liquid medicine inside the drip pot becomes less, the floating plate will automatically drop. At this time, the gravity sensors provided on both sides of the bottom of the drip pot can be squeezed and collided. Then, the two gravity sensors will send the information that the liquid medicine in the drip pot is less to the two alarms and sound an alarm to promptly remind medical staff to deal with the situation in time.
[0019] (5) A sealing seat is provided at the bottom of the floating plate. When the amount of liquid medicine in the drip pot becomes less, the floating plate will drive the sealing seat to move downward. At this time, the sealing seat will seal the inner wall extending through the infusion tube and automatically close the infusion tube, thereby preventing air from entering and improving the safety of the infusion control device.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] This utility provides the following technical solutions:
[0030] Embodiment 1, in order to solve the problem that the existing infusion control device is unstable in controlling the flow rate of the liquid medicine inside the infusion tube 1, discloses:
[0031] An infusion tube 1, a drip pot 2 is arranged below the infusion tube 1, and the diameter of the drip pot 2 is larger than the diameter of the infusion tube 1, and the infusion tube 1 is connected to the top of the infusion tube 1 through the infusion tube 1;
[0032] It also includes: an adjustment seat 3, both ends of which are slotted and penetrated by a pressing rod 4 for sliding installation, and the two pressing rods 4 are symmetrically arranged about the vertical center line of the adjustment seat 3, and the outer ends of the two pressing rods 4 penetrate and extend to the outer sides of both ends of the adjustment seat 3, and the inner ends of the two pressing rods 4 are connected to a clamping plate 5 by screws. A drip pot 2, a floating plate 6 is slidably installed through a slider 14 through a slotted internally, and the floating plate 6 is hollow, and the diameter of the floating plate 6 is smaller than the diameter of the drip pot 2.
[0033] The adjusting seat 3 has slots at both ends inside and arc blocks 9 are rotatably installed, and the two arc blocks 9 are both arc-shaped, and the outer sides of the two arc blocks 9 are connected in sequence with a row of arc grooves 10, and the two rows of arc grooves 10 are evenly spaced on the outer sides of the two pressing rods 4. The adjusting seat 3 has slots at both ends inside and reset springs 11 are provided, and the two reset springs 11 have the same structure, and the outer ends of the two reset springs 11 are connected to the arc blocks 9.
[0034] The two arc blocks 9 are both grooved with torsion springs 12 , and the inner sides of the two torsion springs 12 are both wound with rotating shafts 16 , and the outer ends of the two rotating shafts 16 extend through and extend to the outer sides of both ends of the adjustment seat 3 .
[0035] like Figure 1-Figure 4 As shown, when it is necessary to control the infusion delivery speed of the medicine solution inside the infusion tube 1, it is only necessary to manually press the two pressing rods 4 to retract and move the position, and then the splints 5 connected to the inner ends of the two pressing rods 4 will squeeze and retract the infusion tube 1 at the same time through the anti-skid pads 7. The two anti-skid pads 7 can increase the friction between the two splints 5 and the infusion tube 1 to avoid the phenomenon of misalignment and deviation of the two splints 5 during use in the later stage. When the two pressing rods 4 retract and move, the two return springs 11 will eject the two arc blocks 9 into the two rows of arc grooves 10 in sequence through their own elastic force, and then the two pressing and moving pressing rods 4 can be slidably limited to avoid the phenomenon of misalignment and deviation of the two splints 5 during use in the later stage, thereby improving the use stability of the infusion control device;
[0036] When the two splints 5 need to be reset, it is only necessary to manually rotate the two rotating shafts 16 to drive the two arc blocks 9 to separate from the two rows of arc grooves 10. At this time, the two splints 5 can be separated from the infusion tube 1, and then the two splints 5 can be reset. Finally, the elastic force of the two reset springs 11 can be used to elastically reset the positions of the two rotated rotating shafts 16 to facilitate subsequent repeated operations. The practicality is better and the operation is more time-saving and labor-saving.

[0038] The floating plate 6 is made of EVA ethylene and vinyl acetate copolymer, and the drip pot 2 is provided with gravity sensors 13 on both sides of its bottom, and the top ends of the two gravity sensors 13 correspond to the two ends of the bottom of the floating plate 6. At the same time, the two gravity sensors 13 are connected to the two alarms 15 through electronic signals and circuits, and the two alarms 15 are symmetrically arranged on both sides of the bottom of the adjustment seat 3.
[0039] like Figure 1-Figure 7 As shown, when the volume of the medicine liquid in the drip pot 2 decreases, the float plate 6 will drop along with the decrease in the volume of the medicine liquid. At this time, the two ends of the bottom of the float plate 6 will squeeze and collide with the two gravity sensors 13. Then the two gravity sensors 13 will transmit the information of the decrease in the volume of the medicine liquid to the two alarms 15 and sound an alarm, so as to promptly remind the nearby medical staff to deal with the situation in time.
[0040] Embodiment 3 is different from Embodiment 2 in that the infusion tube 1 can be automatically closed after the infusion is completed, thereby preventing air from entering. The following is disclosed:
[0041] The floating plate 6 has a sealing seat 8 at its bottom, and the outer side of the sealing seat 8 is sealingly connected to the inner wall of the infusion tube 1 .
[0042] like Figure 1-Figure 6 As shown, when the infusion is finished, the volume of the medicine liquid in the drip pot 2 will decrease, and then the float plate 6 will drive the sealing seat 8 to descend, and the sealing seat 8 will be sealed and connected to the inner wall of the infusion tube 1, so that the infusion tube 1 can be automatically closed to prevent air from entering, thereby improving the safety of the infusion control device.
