[0026] The utility model provides an infusion alarm. As a specific embodiment of the infusion alarm of the utility model, see Figure 1 The invention comprises a clamping part 1 for clamping a Murphy-type dropper 9, a dripping rate sensor 3 and a liquid level sensor 4 are arranged on the inner side of the clamping part 1, the clamping part 1 comprises a first fixing clamp 101 and a second fixing clamp 102 arranged up and down, a telescopic mechanism 5 for adjusting the distance between the first fixing clamp 101 and the second fixing clamp 102 is arranged between the first fixing clamp 101 and the second fixing clamp 102, the first fixing clamp 101 and / or the second fixing clamp 102 are provided with a controller, a display screen 2, a dripping rate alarm 6 and a liquid level alarm 7, Figure 1 In the illustrated embodiment, the controller, display screen 2, drip rate alarm 6 and liquid level alarm 7 are all arranged on the second fixing clamp 102, and the drip rate sensor 3, liquid level sensor 4, display screen 2, drip rate alarm 6 and liquid level alarm 7 are all electrically connected to the controller.
[0027] Based on the above technical solution, when performing infusion, the operator can adjust the distance between the first fixing clamp 101 and the second fixing clamp 102 through the telescopic mechanism 5 according to the length of the Murphy's dropper 9, so as to better clamp the Murphy's dropper 9. When the infusion switch 8 is turned on for infusion, the dripping rate sensor 3 monitors the dripping of the droplets in the Murphy's dropper 9 to count and send it to the controller. The controller calculates the dripping rate of the droplets according to the time interval between two adjacent droplets or the number of droplets within a certain period of time, and determines whether the dripping rate is within the set speed. If the dripping rate exceeds the set value, the dripping rate alarm 6 is controlled to alarm. In addition, the liquid level in the Murphy's dropper 9 is monitored by the liquid level sensor 4 and sent to the controller, so as to monitor the remaining amount of infusion. When the liquid level is abnormal, the liquid level alarm 7 is controlled to alarm. In addition, the monitoring information of the drip rate sensor 3 and the liquid level sensor 4 is also displayed on the display screen 2, which is convenient for the operator to view. Therefore, the operator can promptly discover the patient's infusion abnormality when the drip rate and the remaining amount are abnormal, which greatly reduces the workload of nurses and increases the safety of patients' medication.
[0028] In some specific embodiments, the first fixing clamp 101 and the second fixing clamp 102 both include an arc-shaped clamp arm 103 and an arc-shaped clamp arm 2 104. Figure 2 Taking the first fixed clamp 101 shown as an example, the arc-shaped clamp arm 103 and the arc-shaped clamp arm 2 104 are hinged to each other, so the two can rotate relative to each other. When performing the clamping operation, the operator can open the two to enable the two to be clamped on the outer wall of the Murphy's dropper 9, and the arc-shaped clamp arm 103 and the arc-shaped clamp arm 2 104 are each provided with a magnet 105 at one end away from the hinge, thereby preventing the arc-shaped clamp arm 103 and the arc-shaped clamp arm 2 104 from opening, so that the arc-shaped clamp arm 103 and the arc-shaped clamp arm 2 104 clamp the Murphy's dropper 9.
[0029] In some specific embodiments, a sponge anti-skid pad (not shown in the figure) is provided on the clamping surface of the arc-shaped clamp arm 103 and the arc-shaped clamp arm 2 104. The sponge anti-skid pad has a strong compression performance, so that it can fit better on the outer peripheral surface of the Murphy's dropper 9, and increase the friction between the arc-shaped clamp arm 103 and the arc-shaped clamp arm 2 104 and the Murphy's dropper 9, thereby preventing the infusion alarm of the utility model from falling off the Murphy's dropper 9.
[0030] In some embodiments, see Figure 1 The telescopic mechanism 5 includes a plurality of telescopic rods arranged in parallel with each other, and the two ends of the telescopic rods are respectively connected to the first fixing clamp 101 and the second fixing clamp 102. The plurality of telescopic rods can ensure the structural strength between the first fixing clamp 101 and the second fixing clamp 102, and form a better support. It should be noted that the route between the first fixing clamp 101 and the second fixing clamp 102 for connecting different components can be set inside the telescopic rod for a hidden design.
[0031] In some embodiments, see Figure 1 The telescopic rod includes a first telescopic part 501 and a second telescopic part 502. The first telescopic part 501 can be telescopically inserted into the second telescopic part 502, and a locking member 503 is provided between the first telescopic part 501 and the second telescopic part 502. The locking member 503 can be a locking handle. When the locking handle is opened, the first telescopic part 501 and the second telescopic part 502 can slide relative to each other, thereby adjusting the distance between the first fixing clip 101 and the second fixing clip 102. When adjusted to a suitable position, the locking handle is closed to form a lock between the first telescopic part 501 and the second telescopic part 502.
[0032] In some embodiments, see Figure 1 The liquid level sensor 4 includes a first liquid level sensor 401 and a second liquid level sensor 402. The first liquid level sensor 401 and the dripping rate sensor 3 are arranged on the first fixing clamp 101, and the second liquid level sensor 402 is arranged on the second fixing clamp 102. The arrangement of the dual liquid level sensors can better monitor the liquid level. The second liquid level sensor 402 can monitor the lowest liquid level in the Murphy's dropper 9 to avoid insufficient residual amount and prevent the liquid level from being too low and easily entering the air; and the first liquid level sensor 401 can monitor the highest liquid level in the Murphy's dropper 9 to avoid the liquid level being too high and unable to monitor the dripping rate.
[0033] In some embodiments, see Figure 1The liquid level alarm 7 includes a first liquid level alarm 701 corresponding to the first liquid level sensor 401 and a second liquid level alarm 702 corresponding to the second liquid level sensor 402, so that the operator can accurately know whether the liquid level in the Murphy-type dropper 9 is too high or too low. It should be noted that in order to clearly know the warning information corresponding to the first liquid level alarm 701, the second liquid level alarm 702 and the dripping rate alarm 6, text annotations can be made on the alarm.
[0034] In some specific embodiments, the drip rate sensor 3 and the liquid level sensor 4 are both photoelectric sensors, which are non-contact sensors composed of a transmitter and a receiver. The transmitter emits light to the receiver. When the droplets fall, the light is blocked, so that the amount of light received by the receiver is reduced, thereby identifying the passing time and number of the droplets; similarly, the liquid level can also be measured. In addition, the drip rate sensor 3 and the liquid level sensor 4 can also be laser sensors.
[0035] In some embodiments, see Figure 1 , and also includes an auxiliary fixing clamp 10 for clamping the infusion tube 11. The auxiliary fixing clamp 10 can be connected to the clamping part 1 through a connecting line. The auxiliary fixing clamp 10 is clamped on the infusion tube 11 connected to the liquid inlet above the Murphy-type dropper 9. Even if the clamping part 1 falls off the Murphy-type dropper 9, the auxiliary fixing clamp 10 can also pull the clamping part 1 to prevent it from falling on the ground and causing damage. The auxiliary fixing clamp 10 can be a magnetic fixing clamp or a spring clamp, but it is necessary to ensure that the infusion tube 11 cannot be squeezed and deformed too much to affect the infusion speed during the process of clamping the infusion tube 11.
[0036] In some specific embodiments, a wireless module is also included, which is electrically connected to the controller. The wireless module can communicate with the nurse station computer, so that the dripping speed and remaining amount information are transmitted and stored on the nurse station computer, which is convenient for nurses to observe in time.
[0037] It should be noted that the above components of the infusion alarm of the utility model need to be powered. In order to improve its convenience of use, a battery is provided in the first fixing clip 101 or the second fixing clip 102, and the battery is preferably a rechargeable battery and can be recycled. Of course, it is conceivable that the infusion alarm of the utility model can also be provided with a power input port, which is connected to an external power supply to realize power supply.
[0038] It should also be noted that a control panel is also provided on the first fixing clamp 101 or the second fixing clamp 102, and a power switch and a counting switch are provided on the control panel. The control switch and the counting switch are electrically connected to the controller, the power is turned on and off by the power switch, the dripping speed calculation is controlled by the counting switch, and the dripping speed alarm range is set by the counting switch.
[0039] The infusion alarm of the utility model can automatically display the dripping speed and the remaining amount of the infusion through the above technical scheme, and automatically alarm when the infusion is abnormal (the dripping speed is too fast or too slow, the liquid level is too high or too low), and can know the remaining amount of the infusion by calculating the number of drops or judging the liquid level, and alarm when the remaining amount is insufficient, and can record and transmit the real-time monitoring information of the dripping speed and the remaining amount to the computer of the nurse station, so that the nurse can observe in time, which greatly reduces the workload of the nurse and increases the safety of the patient's medication; and the clamping part is provided as a first fixing clamp and a second fixing clamp with adjustable spacing, which can be adjusted for Murphy-type droppers of different models and sizes, so that the nurse can conveniently perform the clamping operation.
[0040] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
[0042] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
