Description

A pressurized perfusion temperature-intensive thoracoscopic surgery irrigation device

technical field

The utility model relates to a flushing device, in particular to a flushing device for pressurized perfusion and temperature-intensive thoracoscopic surgery, which belongs to the technical field of medical instruments.

Background technique

Minimally invasive thoracic surgery has been widely used clinically due to its advantages of small incision, less pain, definite curative effect, safety and reliability. In particular, video-assisted thoracoscopic surgery has achieved good results in the diagnosis and treatment of chest diseases. Before the end of the operation, in order to check whether the airtightness of the lungs is good and whether there is active bleeding in the chest cavity and reduce complications such as postoperative infection, the chest cavity is routinely flushed with 0.9% normal saline. However, due to the small incision of thoracoscopic surgery, it is inconvenient to use a conventional aseptic basin to inject water into the chest cavity for flushing. At present, the principle of siphon or the use of syringes, gloves, funnels and other tools are used for irrigation. The water injection speed is slow, the doctor waits for a long time, it is difficult to control the direction of irrigation, and the area around the incision is easily soaked by irrigation fluid. Such shortcomings have always plagued the operator. In addition, pleural washing as an iatrogenic emergency source often has a certain impact on the body. There is a certain difference in the temperature of the washing fluid, which may cause significant changes in the heart rate and blood pressure of the patient, resulting in arrhythmia or different degrees of cardiac depression. Irrigation with a large amount of room temperature flushing fluid is prone to hypothermia during surgery, prolonging the recovery period from anesthesia, and even affecting the prognosis of patients. Studies have shown that flushing the chest cavity with 37°C normal saline, which is close to the temperature of the chest cavity, has little impact on the body and significantly reduces complications and is suitable for chest cavity flushing. Therefore, a pressurized flushing device for thoracoscopic surgery is designed to quickly and evenly flush the chest cavity, and heat the flushing fluid by heating the flushing pipeline, which can maintain a constant flushing temperature during the flushing process, reduce the stimulation of the flushing fluid to the body, and maintain vital signs. The stability can effectively prevent the occurrence of arrhythmia.

In order to solve the above-mentioned technical problems, the utility model provides a pressurized perfusion temperature-intensive thoracoscopic surgery flushing device, which mainly includes an endoscopic pressurized perfusion pump and a liquid heating device.

In the pressurized perfusion temperature-intensive thoracoscopic surgery flushing device described above, puncture needles are provided at the ends of the two branch pipes of the Y-shaped connection perfusion tube to facilitate connection with the flushing bag.

Further, in the aforementioned pressurized perfusion temperature-intensive thoracoscopic surgery irrigation device, the port of the irrigation component is set as an open port, which can realize two-way communication between irrigation and suction.

The beneficial effect is: the utility model uses a pressurized perfusion pump to drive the perfusion tube through a motor, and setting the perfusion pressure and flow rate can make the flushing liquid enter the chest cavity quickly and evenly, reducing the waiting time for doctors. Insert the heating bag directly into the notch of the heating device, heat the flushing liquid through the infusion pipeline, and set the high temperature and low temperature alarm devices. The temperature of the irrigation fluid can be continuously maintained to meet the needs of the operation and reduce the adverse reactions caused by the temperature difference of the irrigation fluid. Directly inserting the flushing spray head into the chest can control the direction, speed and volume of flushing fluid. Irrigate fluid does not overflow to wet the wound dressing, reducing the chance of increased contamination during irrigation. The Y-shaped connection perfusion tube can connect two bags of flushing fluid at the same time to ensure continuous flushing. It eliminates the frequent replacement of irrigating fluid by surgical personnel and reduces the workload. Using the device does not need to borrow other items, saving medical resources and reducing operation costs; saving the work of pre-heating the irrigation solution and other preparations, and reducing the workload.
