Description

A hepatobiliary surgical drainage device

technical field

The utility model belongs to the technical field of medical instruments, in particular to a drainage device for hepatobiliary surgery.

Background technique

Now clinically, ordinary disposable drainage bags can be used for drainage and storage of patients' urine, chest drainage fluid, peritoneal drainage fluid, bile and other fluids. After removing the packaging of the disposable drainage bag, first pull out the protective cap on the drainage tube joint, connect the drainage tube joint with the external interface of the patient's urinary catheter or other pipelines, and fix the lanyard on the upper end of the drainage bag.

After hepatobiliary surgery patients undergo surgery, the doctor will indwell a variety of tubes, such as T tubes, abdominal drainage tubes, thoracic (abdominal) cavity puncture drainage tubes, nasobiliary ducts, pancreatic ducts, etc., depending on the actual situation of the patient. The model of the interface and the size of the joint caliber are different. Because some of the indwelling tubes are too thin (such as nasobiliary tubes, central venous catheters for abdominal cavity and thoracentesis drainage, etc.), and the connectors of the drainage bag are thicker and have different calibers, it is difficult to connect and fix them. Even if the joints of the two pipes are sealed and fixed with adhesive tape, liquid leakage often occurs, and the joints fall off, etc., which often contaminate the bed sheets, quilt covers, and patient clothes, causing adverse irritation to the patients. It is easy to be contaminated, which increases the workload of nursing staff and the risk of infection.

In addition, the inner diameter of the conical joint in the existing disposable drainage bag is generally 3 mm, and small blood clots or sediment-like stones in the drainage fluid are easy to block here, causing the fluid to accumulate and increasing the chance of infection for patients. When flushing the drainage tube, the current common method is to puncture the drainage tube with the needle of the disposable infusion set and fix it with adhesive tape for flushing, which destroys the integrity of the drainage tube wall, and bacteria enter the lumen, which is easy to cause infection of the patient.

Furthermore, the sewage outlet of the existing disposable drainage bag is located below the drainage bag. When the drainage fluid is dumped, exhausted, and the specimen is collected, it is easy to cause contamination of the hands of the medical staff, the patient's clothing, and the ground, and drainage due to gravity The seal under the bag is not tight, resulting in leakage of drainage fluid.

Although there are usually scales on the drainage bag (the value corresponding to a small scale is 50ml, and the value of the largest scale is 1000ml.), but because of its soft material, the shape becomes irregular after being filled with liquid (some devices are cylindrical in shape ), resulting in a large error between the reading and the actual liquid volume. In order to accurately measure the drainage fluid, the nurse pours the drainage fluid into the measuring cup and then measures it, which increases the workload of the nurse, increases the chance of the nurse being contaminated by the patient's body fluid and blood, and hinders the actual work (especially in the emergency moment of rescuing the patient) It brings inconvenience, and also affects the doctor's diagnosis of the patient's condition, and seriously also affects the patient's later treatment. After the patient indwells the urinary catheter (especially when the bladder is highly inflated due to postoperative dysuria and requires indwelling catheterization), thoracoabdominal puncture and other drainage tubes, after the first drainage of the corresponding amount of fluid, clamping is required Open it again after a period of time, and if the value marked on the drainage bag is inaccurate, it will affect the judgment of the medical staff on the amount.

Patients after biliary tract surgery generally indwell T-tube for 2-4 weeks depending on the situation, and leave the hospital with T-tube after early tube clamping. After 4 weeks, return to the hospital for angiography and extubation. When the T tube was clamped, we found that the switch on the drainage bag could not completely clamp the interception, if the drainage fluid leaked. Then medical personnel need to change the contaminated bed sheets, quilt covers and patient clothes, etc., which will increase the workload of medical personnel. For some patients who have indwelling the T tube for too long, they still have to carry the fixed drainage bag after the tube is completely pinched without discomfort, which is not conducive to protecting the privacy of the patient, and also affects the normal life and image of the discharged patient. In addition, before removing the T-tube after biliary tract surgery, the drainage tube can also be raised according to the doctor's advice, but the drainage tube should not be raised more than 30cm, otherwise it may cause the contraction of the biliary sphincter to block the lower part of the biliary tract, resulting in bile reflux, leading to the feedback of liver cells to stop secretion bile.

Although there are a variety of new, multi-functional drainage bags and drainage devices invented and produced, in clinical practice, they are only suitable for drainage of some conventional pipelines because of their complicated production and subsequent connection and single function. Drainage of various types and joints of drainage tubes placed in postoperative patients of hepatobiliary surgery and observation and treatment of follow-up conditions. Therefore, it is of positive significance to design a humanized drainage device that can not only protect the privacy of patients, but also connect drainage tubes of various types and connectors, and facilitate the operation of medical staff.
