Description

But drainage device of pleuroperitoneal cavity hydrops of leak protection of adjustable catheterization degree of depth

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a leakproof pleuroperitoneal cavity effusion drainage device with adjustable tube placement depth.

Background

Pleural and peritoneal effusions, also known as pleural and peritoneal fluid, are common clinical manifestations of patients. Pleural effusions are the result of the accumulation of pathological fluids within the pleural cavity. The pleural cavity is a potential gap between a visceral layer and a parietal pleura, and 5-15 ml of liquid is contained in the pleural cavity of a normal person and plays a role in lubricating during respiratory motion. Less fluid accumulation (less than 300ml) is associated with more than insignificant symptoms. In the middle and large amount of pleural effusion (more than 500ml), short breath, chest distress, palpitation, dyspnea, even sitting up and breathing accompanied by cyanosis may appear. Hydrops of the abdominal cavity refers to the excessive accumulation of free fluid in the abdominal cavity, and the fluid volume in the abdominal cavity exceeds 200ml in any pathological state, which is called ascites. When ascites occurs in a large amount, the flank bulges like frog abdomen, accompanied by abdominal distension, dyspnea, nausea, vomiting, loss of appetite, feeling of fullness, edema of lower limbs, etc.

Thoracoabdominal cavity puncture drainage is the only rapid and effective method for relieving the clinical symptoms caused by a large amount of hydrothorax and ascites. The thoracoabdominal cavity chemotherapy is to inject chemotherapy medicine into the thoracoabdominal cavity through the drainage tube after thoracoabdominal cavity puncture drainage, so as to increase the local medicine concentration to kill tumor cells. Therefore, chemotherapy of the pleuroperitoneal cavity is also one of the methods for treating primary diseases in malignant pleural effusion and ascites due to malignant tumors. The currently clinically used pleuroperitoneal cavity puncture drainage tube has no leakage-proof device at the skin puncture position, and when the pressure of the thoracic cavity of a patient is increased (such as cough), the pressure of the abdominal cavity is increased (such as defecation), the body position is changed and the skin puncture needle hole is increased, the pleuroperitoneal cavity and abdominal cavity can flow out from the puncture needle hole. At this moment, medical personnel need frequently change dressings such as aseptic gauze in the short time, have increased medical personnel's work load, and have aggravated patient's medical burden. More seriously, the leakage of the pleural effusion and ascites also pollutes the medical environment (the pleural effusion and ascites belong to medical waste which should be specially treated according to the regulations), and especially the leaked pleural effusion and ascites after the thoracoabdominal chemotherapy not only contain tumor cells, but also contain chemotherapeutic drug components. The extravasated hydrothorax and ascites not only increase the infection probability of patients, but also can affect the physical health of family members and medical care personnel of the accompanying bed.

Disclosure of Invention

In order to solve the problems, the invention provides a leakproof pleuroperitoneal cavity effusion drainage device with adjustable tube placement depth.

The invention is realized by the following technical scheme:

a leakproof pleuroperitoneal cavity effusion drainage device with adjustable tube placement depth comprises a drainage tube and is characterized in that the inside of the drainage tube is divided into two channels, one is a drainage channel, and the other is a balloon inflation/liquid channel; a side hole is formed in the outer wall of the drainage channel, and the pleural effusion and the peritoneal effusion enter the drainage channel through the side hole; a plurality of elastic balloons are arranged outside the drainage tube and are communicated with the balloon inflation/liquid channel; the bottom of the drainage channel is connected with a drainage bag, and the bottom of the balloon inflation/liquid channel is provided with a gas/liquid inflation inlet.

In a further improvement, 3 elastic balloons are arranged outside the drainage tube body.

Compared with the prior art, the invention has the following advantages:

the drainage tube is internally provided with a balloon fixing leakage-proof device, so that the leakage phenomenon is effectively prevented. And the sacculus is from airtight puncture needle hole of pleuroperitoneal cavity inboard, it is effectual to leak protection. In addition, the invention can adjust the fixed position according to the pipe placing depth.

Detailed Description

Example 1

As shown in figure 1, the leakproof hydrothorax and peritoneal effusion drainage device with the adjustable tube placement depth comprises a drainage tube 1, wherein the drainage tube 1 penetrates into a pleuroperitoneal cavity 7. The drainage tube 1 is internally divided into two channels, one is a drainage channel 4, and the other is a balloon inflation/liquid channel. A side hole 2 is arranged on the outer wall of the drainage channel, and the pleural effusion and the peritoneal effusion enter the drainage channel through the side hole; a plurality of elastic balloons 3 are arranged outside the drainage tube, and the elastic balloons 3 are communicated with a balloon inflation/liquid channel; the bottom of the drainage channel 4 is connected with a drainage bag 6, and the bottom of the balloon inflation/liquid channel is provided with an air/liquid inflation port 5. Each elastic balloon can contain 5ml of water or the same volume of air, and is in a deflated state when punctured. When the puncture is successful, water or air can be injected through the balloon water injection/air channel, and 5ml, 10ml and 15ml of water (or air with the same volume) are injected, and 3 elastic balloons are respectively expanded. Different elastic balloons can be selected according to the depth of the catheter placement.

In clinic, the drainage is generally smoother in days before the puncture drainage or when the amount of pleural effusion and ascites is large; several days later, the drainage becomes unsmooth with the reduction of the amount of the thoraco-abdominal water, the thickening of the pleural effusion and the adherence of the position of the puncture drainage tube in vivo. In this case, the depth and position of the entire indwelling catheter need to be finely adjusted. According to the aseptic operation principle, the drainage tube can be only pulled out and adjusted outside the body but can not be inserted into the body.

Before partial or all drainage tubes are pulled out, water or air in the saccule needs to be pumped out completely. If the depth of the indwelling tube is deeper, all three balloons are expanded, at the moment, when the puncture tube is pulled out of the body, firstly, 15ml of water or air is completely sucked, and after the puncture tube is pulled out by proper length, the fixed balloon is selected according to the depth of the in-vivo indwelling tube.

If the balloon which is already placed outside the body is not required to be expanded, the ventilation channel between the balloon inside and outside the body can be temporarily clamped and closed, and then air or water in the balloon outside the body is sucked to empty the balloon outside the body.

The above examples are only for illustrating the present invention and are not intended to limit the scope of the present invention, and any simple modification, equivalent change and modification made to the following examples according to the technical spirit of the present invention still fall within the technical scope of the present invention.
