Volume induction type metering valve

Abstract

The invention discloses a volume induction type automatic metering valve device. According to the volume induction type automatic metering valve device, a volume sensor control circuit and an electromagnetic system are mainly used for controlling opening and closing of a valve, and liquid flow metering is carried out by calculating the number of time of opening of the valve. The device is particularly suitable for the condition that the drainage flow metering is needed in body cavity drainage on clinical, by means of the device, the drainage quantity within unit time can be automatically recorded and can be fed back to a user in a manner of special data information, the clinic operation procedure can be simplified, and the clinic daily working quantity is reduced.

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.
