Abstract
Description
Technical Field
[0001] The utility model relates to a closed nursing drainage device, in particular to a closed nursing drainage device, belonging to the technical field of medical devices. Background Art
[0002] Cardiothoracic surgery also includes diseases of cardiac surgery and general thoracic surgery. Cardiac surgery studies cardiac and great vessel trauma, pericardial diseases, congenital heart diseases, acquired valvular heart diseases, ischemic heart diseases, cardiac tumors, great vessel diseases, interventional treatment techniques, surgical treatment of arrhythmias, cardiac pacing and implantable cardioverter defibrillators, dynamic cardiomyoplasty, heart, lung and heart-lung transplantation, etc.
[0003] In clinical practice, the central venous catheter is used as a closed thoracic drainage catheter. When the patient's pleural effusion needs to be injected with medicine or the pleural fluid specimen in the drainage tube needs to be sampled, all these operations require disconnecting the interface between the drainage catheter and the drainage bag, which destroys the sealing of the drainage system, easily causes leakage of pleural effusion and retrograde bacteria to cause thoracic infection, and the operation is also inconvenient. Therefore, a drainage device is needed for dredging. However, the traditional drainage device is not convenient to use. The drainage device needs to be plugged into the patient's body all the time until the drainage is completed. During this process, if other nursing procedures are needed, the drainage device needs to be unplugged and plugged in again when needed, which not only causes unbearable pain to the patient, but may even cause the wound to expand, causing trouble to medical staff and causing irreparable trauma to the patient. Moreover, when the traditional drainage device replaces the collection bottle, the drainage work cannot continue, easily leading to the backflow of the effusion. In the existing patent, a closed nursing drainage device for cardiothoracic surgery, patent authorization number CN217612169U, by setting a shunt mechanism, can perform other operations on the patient without pulling out the drainage tube, avoiding repeated plugging and unplugging of the drainage tube and reducing the pain of the patient. By setting a commutation member, it can ensure the continuous drainage and prevent the backflow of the effusion when replacing the drainage bottle, ensuring the smooth progress of the drainage.
[0004] However, in the patent with authorization number CN217612169U, the drainage bottle is fixed by a placement rack, resulting in the inconvenience of carrying the whole device. When the patient needs to move, it is very inconvenient. In order to enable the patient to move conveniently during drainage, for this reason, we propose a closed nursing drainage device.

[0028] A connecting pipe 4 and an exhaust pipe 5 are respectively inserted through the rubber stopper 3;
[0029] The bottom end of the connecting pipe 4 is conductively connected to a flexible hose 6. A floating ball 7 is installed at the bottom end of the flexible hose 6, and the inner cavity of the floating ball 7 is conductively connected to the bottom end of the flexible hose 6. An air outlet pipe 8 is installed at the bottom of the floating ball 7, and a counterweight ball 9 is arranged inside the floating ball 7, and the outer diameter of the counterweight ball 9 is larger than the inner diameters of the air outlet pipe 8 and the flexible hose 6;
[0030] Connectors 10 are installed at the bottom end of the drainage pipe 2 and the top end of the flexible hose 6, and the connectors 10 are respectively inserted and connected to the top end and the bottom end of the connecting pipe 4;
[0031] It should be noted that when the closed nursing drainage device is in use, one end of the drainage tube 2 is connected to the patient's chest cavity, and the connection head 10 at the bottom end of the drainage tube 2 is connected to the top end of the communication tube 4 inserted into the rubber stopper 3. The top end of the flexible hose 6 located inside the drainage bottle 1 is connected to the bottom end of the communication tube 4 through the connection head 10. After adding an appropriate amount of physiological saline inside the drainage bottle 1, the rubber stopper 3 is installed at the top opening of the drainage bottle 1. During the process of the patient carrying the device, the buoyancy of the floating ball 7 can ensure that the air outlet pipe 8 is always below the liquid level of the physiological saline, and the gravity of the counterweight ball 9 can ensure that the air outlet pipe 8 is perpendicular downward during the flipping process of the floating ball 7, avoiding the situation that the air outlet pipe 8 cannot be guaranteed to be below the liquid level due to jolting during the carrying process. The device has a simple structure, small size, and is convenient to carry and use.
[0032] As Figure 1 shown, connection shaft heads 12 are symmetrically and fixedly connected to the outer wall of the drainage bottle 1, and a limiting part is integrally formed at the end of the connection shaft head 12. A U-shaped handle 13 is rotatably connected to the connection shaft head 12;

[0036] The bottom end of the air outlet pipe 8 is below the liquid level of the physiological saline, and the top end of the air outlet pipe 8 is above the liquid level of the physiological saline;
[0037] It should be noted that it is convenient to observe the working condition inside the drainage bottle 1.

[0039] It should be noted that the sealing effect of the combined part of the connection head 10 and the communication tube 4 is filled by using the sealing rubber rings 11, effectively improving the airtightness.
[0040] Working principle: When in use, one end of the drainage tube 2 is connected to the patient's chest cavity, and the connector 10 at the bottom end of the drainage tube 2 is connected to the top end of the connecting tube 4 inserted at the rubber stopper 3. The top end of the flexible hose 6 located inside the drainage bottle 1 is connected to the bottom end of the connecting tube 4 through the connector 10. After adding an appropriate amount of physiological saline inside the drainage bottle 1, the rubber stopper 3 is installed at the top opening of the drainage bottle 1. During the process of the patient carrying the device, the buoyancy of the floating ball 7 can ensure that the air outlet pipe 8 is always below the liquid level of the physiological saline, and the gravity of the counterweight ball 9 can ensure that the air outlet pipe 8 is vertically downward even when the floating ball 7 flips, avoiding the air outlet pipe 8 not being guaranteed to be below the liquid level due to jolting during the carrying process of the device.
