Description

Technical Field

[0001] The utility model relates to the field of medical drainage equipment, and more specifically, to a pericardial and mediastinal drainage device. Background Art

[0002] The pericardial and mediastinal drainage tube is the most commonly used drainage tube after cardiac surgery. Currently, the most commonly used one is the Y-shaped tube. One short tube of the Y-shaped tube is placed in the posterior and inferior part of the pericardium, and the other short tube is placed in the mediastinum (in the chest cavity in a few patients). The long tube of the Y-shaped tube is led out of the body and connected to a negative pressure suction device to maintain a negative pressure state in the tube to drain the effusion that continues to exude from the wound after surgery.

[0003] Existing pericardial and mediastinal drainage tubes have the following defects:

[0004] 1. Blockage of the tube leads to poor drainage, and in severe cases, pericardial tamponade may occur: Existing pericardial and mediastinal drainage tubes are easily blocked by blood clots, especially near the position of the negative pressure aspirator. On the one hand, patients after cardiac surgery must ensure smooth drainage to avoid pericardial effusion and blood accumulation that affect hemodynamics; but at the same time, patients with large drainage volume use hemostatic drugs to control postoperative blood loss, and hemostatic drugs can induce blood clot formation, which in turn blocks the drainage tube; once the drainage tube is blocked, it may need to be disconnected and replaced at the mildest, or the entire tube may be scrapped at the worst, which not only increases the economic cost, but also increases the risk of infection and even death of patients.

[0005] 2. Fixed position, difficult to drain deeper effusions: The pericardial and mediastinal drainage tubes are placed during cardiac surgery during thoracotomy. During the entire tube-wearing process, from insertion during surgery to removal after surgery, the position of the drainage tube in the body is relatively fixed. In addition, the tube material is rough and hard, and the area where the tube runs is covered with important organs and tissues, making it very difficult to flexibly adjust the position of the tube opening. This results in the inability to drain deeper effusions in the drainage tube. Utility Model Content

[0006] The utility model aims to overcome the defects of the prior art and provide a pericardial and mediastinal drainage device for solving the technical problem that the drainage tube is easily blocked by blood clots.

[0007] The technical solution adopted by the utility model is a pericardial and mediastinal drainage device, comprising a drainage tube, a Y-shaped tube and a cleaning mechanism connected in sequence; the cleaning mechanism comprises a thin cleaning tube, the thin cleaning tube has a first end and a second end, the first end of the thin cleaning tube can be extended into the drainage tube through the Y-shaped tube, and the second end of the thin cleaning tube is used to connect to a negative pressure generating device.

[0012] Furthermore, the cleaning mechanism also includes a quick-release joint, a film sleeve and a quick-connect nozzle; the front end of the quick-release joint is connected to the second end of the straight tube, a through hole for plugging into the cleaning capillary tube is provided in the center, and a vent is provided at the rear end; the film sleeve is sleeved on the cleaning capillary tube, one end of which is connected to the rear end of the quick-release joint, the vent is connected to the inside of the film sleeve, and the length of the cleaning capillary tube is smaller than the length of the film sleeve; one end of the quick-connect nozzle is used to connect to the negative pressure generating device, and the other end is fixedly connected to the second end of the cleaning capillary tube and the other end of the film sleeve respectively.

[0013] Furthermore, the quick-release connector is connected with a closure cover, which is plugged into the front port of the quick-release connector.

The oblique branch tube 6 is connected to the negative pressure suction device. When the cleaning mechanism 3 is not in use, the negative pressure suction device generates negative pressure to attract the accumulated fluid in the drainage tube 2 through the oblique branch tube 6, the part of the straight tube 14, and the Y-shaped tube 1 to perform normal drainage work; when cleaning blood clots, the first end of the cleaning capillary 4 is successively extended into the straight tube 14, the Y-shaped tube 1 and the drainage tube 2 to generate negative pressure, thereby sucking out the internal blood clots.

The two drainage tubes 2 are respectively connected to the two short tubes of the Y-shaped tube 1, and the cleaning mechanism 3 is connected to the long tube of the Y-shaped tube 1. One short tube of the Y-shaped tube 1 is passed through the drainage tube 2 to the lower back of the pericardium, and the other short tube is placed in the mediastinum through the drainage tube 2. A few patients are in the chest cavity, and the long tube of the Y-shaped tube 1 is led out of the body to drain the effusion.

[0030] The Y-shaped tube 1, drainage tube 2 and three-way tube 5 in this solution are all related to the prior art and can be transparent. The closing clamp 7 and quick-connect nozzle 11 are commonly used devices in the medical field and will not be described in detail here.

[0031] Instructions for use: A short tube of the Y-shaped tube 1 is passed through the drainage tube 2 to the lower back of the pericardium, and the other short tube is placed in the mediastinum through the drainage tube 2. For a small number of patients in the chest cavity, the long tube of the Y-shaped tube 1 is led out of the body and connected to the first end of the straight tube 14 of the three-way tube 5.

After the connection is completed, the installation is completed; when there is no blood clot or the blood clot does not affect the normal drainage operation, the second end of the closed straight tube 14 is clamped with a closed clamp 7, and the negative pressure aspirator generates negative pressure. The negative pressure passes through the oblique branch 6, part of the straight tube 14, and the Y-shaped tube 1 to generate negative pressure in the drainage tube 2 to perform normal drainage operations. When the blood clot affects the normal drainage operation; open the closed clamp 7 to control the negative pressure of the negative pressure aspirator to reduce or stop, and bend The straight tube 14 is placed opposite to the short tube of the Y-shaped tube 1 with the blood clot, and then the quick-connect nozzle 11 is pushed to drive the cleaning tube 4 to move, so that the first end of the cleaning tube 4 can smoothly enter the straight tube 14, the Y-shaped tube 1 and the drainage tube 2 in sequence from the second end of the straight tube 14, so that the blood clot inside can be adsorbed and cleaned. The cleaning tube 4 is slender and soft, and can be telescopically moved inside. The position of the first end of the cleaning tube can be flexibly adjusted so as to drain the effusion or clear the blood clot in the pipeline according to the positioning while still ensuring the airtightness of the entire pipeline. The cleaning tube 4 is plugged into the middle through hole of the quick-release connector 8, and the quick-release connector 8 closes the second end of the straight tube 14. The cleaning tube 4 can be connected to an external special negative pressure generating device to adjust the negative pressure in the pipeline as needed to facilitate the suction of blood clots. After cleaning, the second end of the straight tube 14 is clamped with a closing clamp 7 to control the negative pressure aspirator to generate negative pressure, and normal drainage operations can be performed.

[0032] This solves the problem that the original pipeline cannot flexibly adjust the tube position and the drainage tube 2, Y-shaped tube 1, and negative pressure aspirator are often blocked. There is no need to frequently replace the pipeline, while improving tissue compatibility and reducing the risk of complications.
