Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a negative pressure device for auxiliary treatment of severe heart disease. Background Art

[0002] In the nursing work of the intensive care unit, artificial respirators or artificial external chest compression are often used for the rescue of respiratory arrest or respiratory failure caused by various causes. Artificial respirators are a device that uses mechanical methods to maintain and assist patients' breathing. When used, the patient needs to be intubated, and a special endotracheal tube is placed through the mouth or nasal cavity and into the trachea or bronchus through the glottis. Because it is difficult to tolerate the continuous placement of foreign objects into the trachea through the glottis, the patient needs to be sedated continuously, making it difficult for the patient to wake up. At the same time, there is a trachea in the mouth, the patient cannot eat, and it is easy to get infections in the tongue and lips, making the patient feel extremely uncomfortable; artificial external chest compression is that the patient lies flat on the bed, and the medical staff puts the base of one hand on the lower 2 / 3 of the patient's sternum, and the other hand overlaps on it, with both arms straight, relying on the body's gravity to perform vertical and rhythmic compressions toward the spine. The force should be moderate and slightly impactful. Each time you press, the sternum should be depressed 3-4 cm, and then relaxed to allow the sternum to recover, which is conducive to cardiac diastole. The frequency of compression for adults is 60-80 times per minute until the heart recovers.

[0003] Chinese patent (patent number: CN213431592U, discloses a negative pressure device for cardiac resuscitation for critical care). This device does not require the establishment of an artificial airway, and there is no risk of respiratory infection caused by endotracheal intubation. It is comfortable for patients to use and can be tolerated for a long time. It replaces manual chest compressions by nurses, reducing the workload of nurses. It is small in size and relatively inexpensive, reducing the economic burden on patients:

[0004] However, when the above device is in use, the position and direction of the negative pressure port are adjusted only by two universal ball heads, the adjustment range is limited, and it is not easy to fix after adjustment, so the use has limitations. Utility Model Content

[0011] In order to drive the screw to rotate, as a preferred negative pressure device for auxiliary treatment of critical heart disease of the utility model, a motor is installed on the outer wall of the right slider, and the output end of the motor is fixedly connected to the screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
