Pericardial effusion constant-pressure drainage device for cardiology department nursing

Abstract

The invention relates to the technical field of cardiology department nursing, and discloses a pericardial effusion constant-pressure drainage device for cardiology department nursing. The device comprises a drainage device main body, an isolation layer is fixedly arranged inside the drainage device main body, an air bag is fixedly arranged inside the drainage device main body, a heating chamber is fixedly arranged inside the air bag, and the bottom of the air bag is fixedly connected with an air guide pipe. Air in the air bag is heated through the heating chamber in the air bag, the air is continuously heated and can leave through the air guide pipe at the top of the air bag, a sliding rod in the air guide pipe can be jacked to vertically move upwards along with rising of the air, a valveblock in a valve groove vertically moves upwards to enable the air guide pipe to communicate, air voids are generated inside the air bag to attract air at the bottom of the isolation layer, negativepressure is generated at the bottom of the isolation layer, pericardial effusion is continuously attracted through a drainage tube, and the effect of maintaining the drainage device main body to generate stable negative pressure is achieved.

Description

technical field [0001] The invention relates to the technical field of cardiology nursing, in particular to a pericardial effusion constant pressure drainage device for cardiology nursing. Background technique [0002] Constant pressure drainage refers to generating a negative pressure on the outside, inserting the needle into the human body, and using the negative pressure to drain the accumulated fluid in the human body. It is mainly used clinically for the treatment of soft tissue abscesses in the body. It is an effective method. Cardiology Nursing Technology. [0003] At present, the pressure of constant pressure drainage is difficult to maintain constant, and it is necessary for medical staff to keep an eye on the amount and color of the blood flowing out of the patient. Due to the need for long-term care by medical staff, it is a challenge for the energy of medical staff. At the same time, there are medical staff who are negligent and fail to detect the change of the ...
