Description

Retrofitting double-lumen drainage tube connector with single-lumen drainage tube

technical field

The utility model relates to a medical tube and equipment joint, in particular to a double-cavity drainage tube joint refitted with a single-cavity drainage tube.

Background technique

In the course of clinical treatment, there is a situation where it is necessary to replace the previously used common single-lumen drainage tube (such as the commonly used common latex drainage tube) with a double-lumen drainage tube to achieve drainage while flushing and disinfecting. Common situations include: 1. Patients with biliary fistula, elevated pancreatic amylase, anastomotic leakage, hemorrhage, etc. after abdominal surgery need to be changed to negative pressure drainage for local irrigation when conservative observation and treatment are required; 2. Craniocerebral trauma Flushing and drainage as needed; 3. Flushing and drainage of hemorrhage and fluid after thoracic surgery.

For the above-mentioned situation, the currently commonly used clinical solutions mainly include:

First, pre-set a commercial double-lumen drainage tube while performing single-lumen drainage. The drainage tube may cause a waste of medical resources, and the pre-set double-chamber drainage tube will bring some inconvenience to the operation and nursing work;

Second, replace the single-lumen drainage tube with a double-lumen drainage tube after the operation. The disadvantage of this method is that it is relatively difficult to replace the drainage tube after the operation, and it may happen that the distal end of the double-lumen drainage tube cannot be placed in the body to achieve the goal of surgery. area, prone to retrograde infection.

In the face of this clinical need, converting the common single-lumen drainage tube into a double-lumen drainage tube is a direction that can avoid the above problems.

Contents of the invention

The technical problem to be solved by the utility model is to provide a double-cavity drainage tube joint refitted with a single-cavity drainage tube, so that the single-cavity drainage tube can be refitted into a double-cavity drainage tube on-line during the drainage process. The structure is simple, easy to use, and safe. reliable.

The technical solution adopted by the utility model to solve the technical problem is to provide a double-cavity drainage tube joint refitted with a single-cavity drainage tube, including a straight tube joint and a side tube joint connected in the shape of a "bu" shape. The pipe joint is a double-sleeve structure, the inner sleeve cavity of the side pipe joint communicates with the lumen of the straight pipe joint, the outer sleeve cavity of the bypass pipe joint is filled with waterproof filter material, and the outside of the outer sleeve cavity The end is provided with a cover body with air holes on the cover body, and the inner end is a pipe body of a straight pipe joint with air holes on the corresponding pipe body.

When the connector is in use, one end of the straight pipe connector at an obtuse angle relative to the side pipe connector is connected to a single-cavity drainage tube, and the other end at an acute angle is connected to a negative pressure device. Inside and extending to the distal end of the active single lumen drain.

The included angle between the bypass pipe joint and the straight pipe joint is 30°-60°.

The included angle between the side pipe joint and the straight pipe joint is 45°.

The two ends of the straight pipe joint are provided with tapered thread anti-off structures.

The bottom of the tapered thread anti-off structure is provided with an intubation stopper.

An inscribed structure is formed between the inner casing and the outer casing of the bypass pipe joint.

The outer end of the inner casing of the bypass pipe joint is provided with a sealing film sleeve capable of cooperating and sealing with the flushing fluid infusion tube.

The straight pipe joint and the side pipe joint are integrally formed connection structures.

Beneficial effect

Through the joint of the utility model, the common single-lumen drainage tube can be refitted into a double-lumen drainage tube on-line in the process of drainage in clinical practice, avoiding the waste risk of pre-indwelling or postoperative replacement of the drainage tube in clinical practice. Inconvenient and risky to operate, simple in structure and easy to use. The side pipe joint can make the straight pipe joint of the drainage communicate with the outside air, maintain pressure balance, prevent excessive negative pressure of the drainage from causing damage to the internal organs of the human body, and effectively prevent the leakage of the drainage liquid, which is safe and reliable.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

As shown in Figure 1, a double-cavity drainage tube joint refitted with a single-cavity drainage tube includes a straight tube joint 1 and a side tube joint 2 connected in the shape of a "bu", the side tube joint 2 and the straight tube joint 1 The included angle between them is 45°, which is convenient for the insertion of the flushing fluid infusion tube and leaves enough space for the drainage fluid to flow out. The straight pipe joint 1 and the side pipe joint 2 are integrally formed connection structures.

Both ends of the straight pipe joint 1 are provided with a tapered thread anti-off structure, and the bottom of the tapered thread anti-off structure is provided with an intubation stopper 4 . One end of the straight pipe joint 1 and the side pipe joint 2 at an obtuse angle is used to connect to the single-lumen drainage tube in use, and the other end at an acute angle is used to connect to a negative pressure drainage device.

The side pipe joint 2 is a double casing structure, and the inner casing and the outer casing are inscribed. The inner casing cavity of the side pipe joint 2 communicates with the lumen of the straight pipe joint 1, and is used to insert the flushing fluid infusion tube and extend into the single-lumen drainage tube, and extend to the distal end of the single-lumen drainage tube. The outer end of the outer end is provided with the sealing film sleeve 5 that can cooperate with the flushing fluid infusion tube to seal. The inside of the outer tube cavity of the side pipe joint 2 is filled with waterproof filter material, as shown in Figure 2, the outer end of the outer tube cavity is provided with a cover and the cover has air holes 3, and the inner end is the tube of the straight tube joint 1. body and the corresponding tube body is provided with air holes 3, and the overcoat tube cavity can make the drainage straight tube joint 1 communicate with the outside air, maintain pressure balance, and prevent excessive drainage negative pressure from causing damage to the internal organs of the human body.

When this connector is in use, first connect the single-lumen drainage tube and the negative pressure drainage device in use to both ends of the straight tube connector 1, and then insert the flushing fluid infusion tube from the inner tube of the side tube connector 2, so that the common The single-lumen drainage tube is modified into a double-lumen drainage tube, which has simple structure, convenient operation and strong clinical practicability.
