Description

Split drainage device

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a split drainage device.

Background

The clinical drainage tube is widely used, such as wound drainage of postoperative patients, drainage of pleuroperitoneal cavity effusion, urine drainage and the like, but due to limited capacity of a drainage bag, drainage liquid needs to be poured in time after being led out, otherwise, the drainage is unsmooth, drainage liquid is returned, hydronephrosis and the like are caused.

At present, the clinical practice is to turn on a switch at the bottom of the drainage bag to enable drainage liquid to flow into the measuring cup and then pour the drainage liquid into the sewage pool by holding the measuring cup. In order to avoid cross infection and reduce the occurrence of nosocomial infection, the special staff of the measuring cup is dedicated, and the hand washing and glove replacement are needed for pouring drainage liquid to each patient.

The method described above has several disadvantages:

1. the sewage pool is far away from the patient, a nurse usually needs to pour drainage liquid to a plurality of patients, and the nurse walks back and forth in a disease area with the measuring cup, so that the workload is high, and the risk of splashing the drainage liquid is also caused;

2. the capacity of the measuring cup is usually one liter, the minimum scale is 50 milliliters, and the measurement is inaccurate;

3. the drainage liquid is possibly splashed when being connected into the measuring cup and poured into the sewage pool, so that clothes and surrounding environment are polluted, peculiar smell exists, and bacteria are easy to breed;

4. the nurse needs to wait for drainage liquid to flow into the measuring cup at the bedside of the patient one by one, which takes a long time;

5. a plurality of drainage tubes are arranged on a part of patients, one measuring cup can not receive all drainage liquid at one time, and the drainage liquid is required to be poured into a sewage pool and then returned to the bedside for operation;

6. when a drainage liquid specimen is left, the infection is easy, the cost is high, and the operation is complex;

7. intra-abdominal pressure is inconvenient to monitor.

The conventional drainage bag and drainage tube have no interface for intra-abdominal pressure monitoring, and devices such as a tee joint, a self-made connecting tube and the like are required to be additionally connected, so that the operation is inconvenient and the sterility of the device cannot be guaranteed. The conventional drainage tube has no sample collection interface, and 2 methods are adopted for sample collection:

the first method requires pulling out the drainage bag connector from the end of the drainage tube on the patient and then withdrawing the specimen from the end of the drainage tube. The disadvantages of this approach are: the drainage bag can not be frequently pulled out of the drainage tube on the patient, and bacteria are easily brought into the body by frequent insertion and pulling, so that the requirement of controlling the hospital infection is not met; secondly, because the drainage bag joint made of plastic materials is inserted into the drainage tube made of silica gel or rubber materials and then is communicated, the packaging is tight, the uncoupling difficulty is high, repeated disinfection is needed before uncoupling and in the uncoupling process, and the tail end of the drainage tube of a patient and the drainage bag joint are required to be packaged by sterile gauze, so that the operation difficulty is high and the cost is high.

The second method does not need to pull out the drainage bag joint from the tail end of the drainage tube on the patient, and directly inserts the syringe needle into the drainage tube to extract drainage liquid. This method not only involves the risk of needle sticks, but also is prone to catheter rupture, resulting in leakage of drainage fluid and bacterial entry into the catheter and into the patient, causing infection.
