Embodiment Construction

[0018]As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, and Fig. 8, the present invention has at least a part of it transparent and convenient to see the inner casing 1, from the described A pressure regulator 2 that pumps out gas and fills it with gas in the box to form a dynamic negative pressure in the box, a vent pipe that communicates with the box and the pressure regulator, and a plurality of sleeve-shaped or sleeve-shaped seals made of flexible materials Connector 3. Described box body 1 is formed by fitting butt joint of upper section casing 11, middle section casing 12, and lower section casing 13. Specifically, there may be first plugs (protrusions) around the bottom of the upper section casing, and the middle section casing has a first plug (protrusion). There is a first open groove (groove) matching with the first plug of the upper housing around the upper end, a second plug is provided around the bottom of the middle housing, and a second plug is...

Abstract

The invention is concerned with simulation thorax dynamic negative pressure chest opening Operating Compartment, relating to box, press adjuster, gas tube and airproof connector. The box has upper, middle and down segments and the joint area of the down and middle segments at the front and back ends of the box have holes for neck and down abdomen. The down and middle segments of shell at left and right side of box and the joint area of the middle and upper segments of shell have holes for upper limbs to keep the lung organization take air exchange in primary manner when the thorax of body is open. It avoids forming gas chest of lung organization when the pleura cavity connecting with environment and the pulmonary collapse and pulmonary atelectasis formed by the disappearance of the negative press to pleura cavity, and avoids the damnification of windpipe of sickness for intubatton. The sick can renew as quickly as possible in low-grade anesthetic with few secretion of breath path and keep the function of ventilating.

Description

technical field [0001] The invention relates to a medical instrument for surgical thoracotomy, in particular to a thoracotomy operating cabin under dynamic negative pressure simulating chest cavity. Background technique [0002] At present, surgical treatment of chest diseases such as lung cancer and esophageal cancer requires general anesthesia to make the patient unconscious and spontaneous breathing disappears, and then perform tracheal intubation through the oral cavity, connect the anesthesia machine through the tracheal intubation, and assist breathing through pressurized ventilation; Put the operation position, after disinfection, laying sterile surgical drapes and other preparations, the thoracotomy can be performed. This technology has been maturely used for about 60 years, and can solve the problems of most patients. Its disadvantages are: ① Regardless of the size of the operation or whether it is complicated or not, the degree of anesthesi...
