Embodiment Construction
[0031] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention.
[0032] Such as figure 1 As shown, a special negative pressure drainage device for thyroid surgery includes a thick drainage tube 1 , a thin drainage tube 2 and a negative pressure device 3 . The material of the thick drainage tube 1 , the thin drainage tube 2 and the main drainage tube 4 is the same as that of the drainage tubes commonly used in hospitals, for example, they are all medical PVC transparent hoses. The negative pressure device 3 is an electric vacuum suction pump, and the suction port of the electric vacuum suction pump is detachably connected with the main drainage tube 4 . The suction port of the electric vacuum suction pump is locked and connected with the main drainage tu...

The invention belongs to the technical field of medical apparatuses, and discloses a negative pressure drainage device special for thyroid surgeries. The negative pressure drainage device comprises awide drainage pipe, a fine drainage pipe, a negative pressure device and a main drainage pipe, wherein a first drainage cavity and first injection cavities are formed in the wide drainage pipe in a radial direction; a plurality of first drainage holes and a plurality of first injection holes are formed in the pipe wall of the wide drainage pipe; the first drainage holes communicate with the firstdrainage cavity; the first injection holes communicate with the first injection cavities; a second drainage cavity and second injection cavities are formed in the thin drainage pipe in the radial direction; a plurality of second drainage holes and a plurality of second injection holes are formed in the pipe wall of the fine drainage pipe; the second drainage holes communicate with the second drainage cavity; and the second injection holes communicate with the second injection cavities. The negative pressure drainage device disclosed by the application can reduce the cost, reduce the probability that a doctor wrongly takes the drainage pipe, can avoid the situation that under the situation that the pressure difference is high, liquid flows to the negative pressure device, and can also inject liquid medicines to a wound of a patient.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to a special negative pressure drainage device for thyroid surgery. Background technique [0002] Due to the large wound surface separated during thyroid surgery, there will be a certain amount of exudate after surgery. At the same time, it is also necessary to pay attention to whether there are complications such as wound bleeding and tracheoesophageal fistula after operation. Therefore, a drainage device must be placed after thyroid surgery. There are currently two types of thyroid surgery: conventional open thyroid surgery and laparoscopic thyroid surgery. Conventional open thyroid surgery has a larger incision, and a drainage device with a thicker drainage tube needs to be placed; laparoscopic thyroid surgery has a smaller incision, and a drainage device with a thinner drainage tube needs to be placed. This requires the hospital to be equipped with two types of drainag...
