Volume inductive metering valve

Abstract

The invention discloses a volume inductive metering valve. A circuit is controlled mainly through a volume sensor. An electromagnetic system controls opening and closing of the valve, and liquid flowis metered by calculating the opening frequency of the valve. The volume inductive metering valve is particularly suitable for the condition that drainage flow needs to be metered for clinical body cavity drainage, can automatically record the drainage flow within a unit interval and feeds the drainage flow back to users in a specific data information manner, thereby simplifying the clinical operation procedures and relieving the clinical daily workload.

Description

technical field [0001] The invention relates to a capacity-sensing automatic metering valve device, which is mainly used for measuring liquid flow, and is mainly used in the case where drainage of a body cavity needs to be measured clinically. The inventive device can automatically record the drainage amount per unit time, and Feedback to the user in the form of specific data information can simplify the clinical operation process and reduce the daily clinical workload, which belongs to the field of clinical diagnosis and treatment. Background technique [0002] Clinically, in many cases of surgery, a drainage tube needs to be indwelled in the surgical area. The purpose of the indwelling drainage tube is to drain the exudate in the surgical area and to observe whether there is rebleeding after the operation. Hematoma drainage, external ventricular drainage, lumbar cistern drainage, subcutaneous drainage, abdominal drainage in general surgery, surgery area drainage, breast an...

Problems solved by technology

[0003] Under normal circumstances, the record of the drainage volume in the operation area requires the nursing staff to pour the drainage fluid in the drainage bag into the measuring cylinder at a fixed time every day, and record the measurement information in the nursing record after observing the scale data of the measuring cylinder. Each patient needs to prepare a Graduated cylinder, or record again after emptying the graduated cylinder, the operation is cumbersome, the workload of the nursing staff is large, and it is easy to cross infection

[0004] Drainage tubes in the surgical area are a common operation in surgical diagnosis and treatment, which is a daily operation, and the amount of medical and nursing operations in clinical work is relatively large. However, in addition to daily measuring cylinders, there is no device and method that can solve the above problems in clinical practice.
