Problems solved by technology

However, since the infused liquid is prone to crystallization, the infusion line is prone to blockage, resulting in medical accidents
In the existing fluid control equipment, there is no technical solution that can effectively detect this kind of pipeline blockage

Embodiment Construction

[0048] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation of the invention will now be described with reference to the accompanying drawings.

[0049] In order to make the drawings concise, the figures in each figure only schematically show the relevant parts of the present invention, and do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components having the same structure or function is schematically shown, or only one of them is marked. In this article, "upper", "lower", "front", "rear", "left", "right", etc. are only used to indicate the relative positional relationship between related parts, rather than to limit the absolute position of these related parts . In this article, "first", "second", etc. are only used to distinguish each other, not to indicate the degree of importance and ord...

Abstract

The invention discloses fluid control equipment for detecting blocking events. The equipment comprises a control module, a valve element driving device, a fluid driving device and a deformation detection sensor; wherein the deformation detection sensor is arranged on a corresponding target position of an infusion pipeline system matched with the fluid control equipment, and used for detecting a deformation value of an infusion pipeline at the target position; the control module controls the fluid driving device and the valve element driving device for corresponding driving actions, and can record an initial deformation value and a blocking deformation value at the target position corresponding to the infusion pipeline system, in the subsequent process, a current deformation value corresponding to the target position is read in real time from the deformation detection sensor, by comparing the deformation value with the initial deformation value and the blocking deformation value, it isjudged whether a blocking event occurs or not, thereby the pipe blocking event can be timely found, and the risk of medical accidents due to the pipe blocking are reduced.

Description

technical field [0001] The present application relates to the technical field of medical infusion, in particular to a fluid control device. Background technique [0002] In the field of medical and health care, it is a well-known requirement to deliver fluids such as medicinal liquid or nutritional liquid to the body of a patient at a certain speed. In order to meet this demand, a fluid control device for automatically infusing medicine or nutrient solution into a patient's body has appeared in the industry, and the typical device is a liquid infusion pump and an associated infusion line. The source end of the infusion line is connected to a liquid source such as a drug bottle or a nutrient solution bag, the target end is placed in the patient's body, and the middle part of the infusion line is a soft line. The liquid infusion pump includes a fluid drive device, and the fluid drive device generally includes a pump wheel and a power device that drives the pump wheel to rotat...
