Description

Intelligent external drainage monitoring device

Technical Field

The invention relates to the technical field of surgical drainage monitoring, in particular to an intelligent external drainage monitoring device.

Background

External drainage is a common postoperative procedure for clinically draining various kinds of fluid (or gas) which are unnecessary or harmful to the operation site and wound of a patient out of the body, and the fluid includes effusion, effusion or other fluids in the body, such as blood, serum, pus, bile, lymph and even urine, etc. The external drainage procedure is typically accomplished by a surgeon or interventional radiologist by placing an external drainage tube in the patient to drain these fluids out of the body.

Two main purposes of external drainage are treatment and prevention. Therapeutic drainage is to guide the pus, exuded blood, tissue fluid and other fluids accumulated in the tissues or body cavities of patients to the outside of the body so as to prevent infection caused by fluid accumulation and play a role in promoting wound healing and patient recovery. The therapeutic drainage has definite indications, including dropsy, hematocele, empyema, pneumatosis, necrotic tissues, foreign bodies or fistula in the abdominal cavity, and is mainly applicable to infectious diseases, liver and gall diseases and gastrointestinal diseases; the preventive drainage aims at monitoring, is generally used for observing whether active bleeding exists or not, or whether postoperative complications such as gastric, intestinal, biliary tract and pancreatic leakage occur or not, and is convenient for doctors to take effective treatment measures in time.

In order to accurately observe and judge the rehabilitation process of a patient, the flow and characteristics of drainage fluid must be carefully measured and recorded during the drainage process of the patient, and the change of the property or volume of the drainage fluid must be monitored so as to identify various complications causing fluid (especially bile or pancreatic secretion) or blood leakage, or calculate the loss amount of body fluid to assist intravenous fluid replacement, and the observation and measurement processes are performed manually and intermittently at present.

At present, the clinical external drainage has the following problems, firstly, the external drainage tube is frequently blocked or falls off in the using process, and is difficult to find and dispose in time. When the external drainage tube is blocked or falls off, the liquid accumulated in the body can not be discharged, thereby possibly causing infection or other complications; secondly, when the drainage fluid is blood, if abnormal conditions such as high blood flow rate or large amount and the like occur in the drainage process, medical staff often cannot find and handle the abnormal conditions in time, particularly when the light is poor at night and the hands of the medical staff are insufficient; third, the measurement of the amount of drainage is currently measured and recorded manually by a nurse pouring the drainage fluid from the drainage bag into a measuring cup. The manual measurement and recording mode is time-consuming and labor-consuming, and the exposed drainage liquid is easy to contact with surrounding air, environment or personnel, so that the risk of cross infection between patients and nurses is increased.

Since the drainage fluid may intermittently flow out of the body and the amount of drainage fluid is small in some cases, it is difficult to directly measure the flow of the drainage fluid with a conventional flow sensor, and the flow sensor is large in size, expensive and not suitable for disposable use.

It can be understood that the flexible bellows 302 can guide the drainage liquid into the drainage bag 6 and at the same time can eliminate the interference of the weighing measurement of the weighing sensor 2 due to the rigidity of the bellows and the movement or force applied to the upper outer drainage tube 7. It should be noted that the axial stiffness of the flexible bellows 302 should be much less than the bending stiffness of the two force-sensitive elastic deformation cantilever beams 202, so that the situation that the sensitivity of the weighing sensor 2 is affected due to the too large axial stiffness of the flexible bellows 302 can be avoided, and the weighing sensor 2 can accurately measure the weight of the drainage fluid. Specifically, the flexible corrugated tube 302 may be made of polymer materials such as medical silica gel and soft plastic, and the upper joint 301 and the lower joint 303 may be made of materials such as medical plastic, so as to meet the use requirements.

It can be understood that the upper connector 301 can be rapidly and repeatedly clamped in the second bayonet 1011 to achieve rapid installation of the flexible bellows kit 3 on the bracket 101 of the fixed connector 1 or rapid detachment from the bracket 101 of the fixed connector 1; the upper connector 301 can be well limited on the support 101 of the fixed connecting piece 1 by arranging the second upper limit blocking part and the second lower limit blocking part 3011, so that the position of the upper connector 301 is fixed, and the upper connector 301 is fixed to prevent the stress or movement of the outer drainage tube 7 from being transmitted to the weighing sensor 2 through the flexible corrugated tube kit 3 due to the fact that the outer drainage tube 7 connected to the upper connector 301 inevitably moves or is stressed in the using process, and therefore interference caused by the measuring process of the weighing sensor 2 due to the movement or stress of the outer drainage tube 7 is reduced or avoided.

Optionally, the second bayonet 1011 is semicircular, so that the clamping is more convenient.
