Description

Continuous liquid level detection negative pressure drainage system

Technical Field

The utility model relates to the field of medical instruments, in particular to a negative pressure drainage system for continuous liquid level detection.

Background

The negative pressure drainage system is a surgical treatment means for sucking or removing purulent effusion, necrotic tissues, infected substances, surgical liquid or gas and the like in body cavities, organs or tissues of an organism and establishing an open channel with the outside so as to achieve the purpose of treatment, and is also an important component in surgical treatment. The wound healing promoting agent has the advantages that the wound healing promoting agent is developed rapidly in wound treatment and thoracic drainage in recent years, and can accelerate blood circulation of a wound part, relieve edema, inhibit bacterial growth, stimulate granulation tissue growth and accelerate wound healing in wound treatment. The thoracic drainage can relieve the pressure of the thoracic cavity, relieve the compression of body fluid and gas on heart and lung tissues and is beneficial to the re-opening and recovery of the lung tissues.

The doctor can only rely on experience to look over the absorption volume of purulent hydrops, infected material or operation liquid etc. from the scale of drainage bottle or drainage bag in the use of current negative pressure drainage system for judge patient's treatment condition, and can't obtain the data in the treatment process directly perceivedly. And the current negative pressure drainage system is used for treating at different periods, so that the time of medical staff and patients is required to be increased to check whether the absorbed waste liquid is full, and the workload of the medical staff and the psychological pressure of the patients are invisibly increased.

The prior art has the following defects:

on current surface of a wound treatment and thoracic drainage surgery treatment technique, need the doctor to possess a large amount of experiences and go to judge patient's treatment condition, can't judge patient's recovery degree directly perceived through the waste liquid volume of drainage bottle drainage. The judgment is carried out by the experience of doctors, so that the overtreatment is possible, the timely recovery of the patients is not facilitated, and the treatment cost is increased.

The different sick degree of different patients receives the volume influence of drainage bottle or drainage bag, and the time that the waste liquid was collected the liquid fullness can't be confirmed, causes medical personnel too much time energy to go to pay close attention to the collection process easily, and causes patient's psychological burden.
