Embodiment 1

[0064] This embodiment provides an infusion control system that adjusts the infusion volume according to the urine output, such as figure 1 As shown, including microprocessor unit, infusion pump, urine volume and urine flow velocity measurement unit;

[0065] The infusion pump acts on the infusion tube to control the infusion speed;

[0066] The microprocessor unit controls the infusion pump to adjust the infusion according to the measurement results of the urine volume and urine flow velocity measurement unit, combined with the preset ratio Q of infusion volume and urine output built in the microprocessor unit. speed;

[0067] The urine volume and speed measurement unit is applied to the urine bag and includes:

[0068] Urine bag weight detection module for real-time measurement of the weight G of the urine bag N ;

[0069] Urine flow velocity conversion module, used to obtain the urine flow generation velocity V per unit time N ;

[0070] The microprocessor unit genera...

Embodiment 2

[0083] Such as figure 2 In this embodiment, on the basis of Embodiment 1, the system also includes a rigid protection device for the urine bag weight detection module to protect the urine bag weight detection module from being damaged when it is overloaded;

[0084] The rigid protection device is arranged in the vertical downward direction of the urine bag weight detection module and has a suspension interval of 0.5mm-3mm between the urine bag weight detection module; preferably, the rigid protection device is set There is a 1 mm suspension space between the urine bag weight detection module and the urine bag weight detection module in the vertical downward direction.

[0085] When the weight of the urine bag is overloaded, the urine bag weight detection module is in contact with the rigid protection device, and the rigid protection device prevents the urine bag weight detection module from continuing to deform and mechanically protects the urine bag weight detection module. ...

Embodiment 3

[0088] This embodiment is on the basis of embodiment 1 or embodiment 2, as figure 1 As shown, the system also includes an infusion volume and infusion speed measurement unit applied to the infusion bag, including:

[0089] Infusion bag weight detection module, used to measure the weight G of the infusion bag in real time Y ;

[0090] The infusion speed monitoring module works synchronously with the urine flow speed conversion module, and is used to obtain the weight G of the infusion bag measured by the infusion bag weight detection module every preset interval T Y , analyze the variation ΔG of the weight of the infusion bag twice adjacent Y ;

[0091] The microprocessor unit also includes a data comparison module, which compares the variation ΔG of the weight of the infusion bag Y The variation ΔG of the weight of the urine bag at the same moment N Compare, fine-tuning the infusion error:

[0092] When (ΔG Y :ΔG N )Y :ΔG N = Q;

[0093] When (ΔG Y :ΔG N )>Q, the m...

Abstract

The invention provides an infusion control system and method for adjusting an infusion amount based on a urine output. The infusion control system comprises a microprocessor unit, an infusion pump, a urine volume and urine flow velocity measuring unit, an infusion amount and infusion velocity measuring unit, an operation monitoring module, a man-machine interface and the like. The infusion pump acts on an infusion tube for controlling the infusion velocity; the microprocessor unit receives a measurement result from the urine velocity measuring unit, controls the infusion pump to adjust the infusion velocity according to the urine velocity in accordance with a body fluid intake and output balance principle; the urine volume and urine flow velocity measuring unit is applied to a urine bag and used for measuring a weight GN of the urine bag in real time and calculating to obtain a generated urine flow velocity VN; and the operation monitoring module is responsible for monitoring if the system works normally, as well as alarming and triggering protective actions in case of anomalies. By adopting the balanced infusion control system and method provided by the invention, a balance between the infusion amount and the urine output can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion control system and method for adjusting infusion volume according to urine output. Background technique [0002] Due to the objective needs of the patient's specific condition, it is required that during the treatment process, there are certain requirements for the amount of intravenous infusion and the speed of infusion per unit time, otherwise it may affect the therapeutic effect and even endanger the patient's life. Instruments for measuring and controlling the quantity and speed of infusion per unit time have also emerged at the historic moment. Currently, infusion pumps are commonly used in hospitals as a medical instrument for measuring and controlling the amount and speed of infusion per unit time. The infusion pump is an instrument that can accurately control the number of infusion drops or the flow rate of the infusion, so as to ensure that the dru...
