Description

abdominal drainage tube

technical field

The utility model relates to a drainage tube, in particular to an abdominal cavity drainage tube used in hepatobiliary surgery, and belongs to the technical field of medical auxiliary equipment.

Background technique

After hepatobiliary surgery, abdominal drainage tubes are commonly used to drain accumulated blood, fluid, and empyema. For patients with inflammatory empyema, in addition to intravenous antibiotics after the operation, local antibiotic treatment is also required, and drugs need to be injected into the infected part of the abdominal cavity through the drainage tube to improve the curative effect and accelerate healing. The current commonly used drainage tube includes a cone and a drainage hose connected to the cone, and a drainage hole is arranged at the front end of the drainage hose. Since the peritoneal drainage tube with this structure has only one lumen, the injected medicine is easily polluted by the drainage fluid, and the lumen of the drainage tube is too thick to be connected with the syringe, and the injected medicine is easy to leak out and cannot fully reach the infection site, which is not conducive to the patient. recover.

Utility model content

Aiming at the above-mentioned defects in the prior art, the utility model provides a novel peritoneal drainage tube which can prevent the injected medicine from being polluted by the drainage fluid and is convenient for injection.

The utility model is realized through the following technical solutions: an abdominal cavity drainage tube, including a conical body, a drainage hose connected with the conical body, the drainage end of the drainage hose has several drainage holes, and its special feature is that the The drainage output end of the drainage hose has a branch pipe communicating with the lumen, the cone is provided with a cavity extending through its axial length, and a core tube is arranged in the drainage hose, and one end of the core tube It is connected with the cone and communicates with the cavity of the cone, and the other end protrudes from the branch pipe.

During specific use, the drainage hose is placed on the affected area under the guidance of the cone, and the effusion in the affected area enters the cavity of the drainage hose from the drainage hole on the drainage hose and is discharged from the drainage output end of the drainage hose; When the medicine is injected into the affected part, a syringe is used to inject the medicine into the core tube, and the medicine is injected into the affected part through the core tube from the cavity of the cone. Since the core tube used for injecting medicine does not communicate with the lumen of the drainage hose, the injected medicine will not be polluted by the drainage fluid.

In order to prevent the core tube from being polluted and to facilitate the injection of medicines, the end of the core tube protruding from the branch tube is provided with a connector that can be connected with a syringe. The connecting head can not only seal the core tube to avoid pollution, but also facilitate the injection of medicine. When injecting the medicine, the injection head of the syringe is connected to the connecting head so that the injection can be conveniently performed, and the medicine is not easy to leak out.

In order to be placed on the affected part conveniently, the core tube is a medical plastic hose or a silicone tube.

The beneficial effects of the utility model are: the utility model has a simple structure, and by setting a separate core tube for injection in the drainage hose, the injected medicine is not easy to be polluted by the drainage fluid, which is beneficial to the recovery of the patient; secondly, it passes A connecting head that can be connected with a syringe is arranged on the core tube for injecting medicine, so that injecting medicine is more convenient and the operation is more convenient.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

In the figure: 1. drainage hose, 2. drainage hole, 3. cone, 4. cavity, 5. core pipe, 6. branch pipe, 7. connector.

Detailed ways

Below by non-limiting embodiment and in conjunction with accompanying drawing, the utility model is further described:

As shown in FIG. 1 , an abdominal drainage tube includes a cone 3 and a drainage hose 1 connected to the cone 3 . The drainage end of the drainage hose 1 has several drainage holes 2, and the drainage output end of the drainage hose 1 has a branch pipe 6 communicating with the lumen. The cone 1 is provided with a cavity 4 extending through its axial length. A core tube 5 is arranged in the drainage hose 1, one end of the core tube 5 is connected with the cone 1 and communicates with the cavity 4 of the cone 1, and the other end stretches out from the branch tube 6, and at the protruding end A connector 7 that can be connected to a syringe is provided. The core tube 5 in this embodiment is a flexible tube, which can be a medical plastic tube or a silicone tube, and the drainage tube 1 is a silicone tube.

Other parts of the present utility model adopt prior art, do not repeat them here.

The utility model has the advantages of simple structure and convenient operation, and can be widely used in abdominal cavity drainage.
