Problems solved by technology
[0005] In this way, the oxygen cylinders have not been rationally utilized. If multiple patients need to inhale oxygen and the number of oxygen cylinders is insufficient, it is easy to cause medical accidents. When treating, it will make medical institutions fall into an embarrassing situation of stretching

The present invention provides an integrated module for oxygen inhalation and negative pressure suction, including a valve body and an air inlet joint arranged on the valve body, a first air outlet terminal, a second air outlet terminal, a regulating needle valve, a negative pressure generator, and a negative pressure safety valve The valve body is provided with flow channel Qf2, flow channel Qf3, inclined hole, annular chamber Qb1, annular chamber Qb2, channel Qb6 and air chamber Qb9; There are flow channel Qf4 and flow channel Qf6. The second air outlet terminal is provided with flow channel Qf5 and flow channel Qf7. The negative pressure generator includes nozzle, diffuser, muffler cover and muffler sponge. There is an annular cavity in the large opening end of the nozzle. Qb3, an injection chamber Qb4 is provided in the small opening end, a channel Qb7 is provided inside the safety valve body, a round hole Qb8 is provided on the large end of the safety valve body, a mixing chamber Qb5 and a diffusion chamber Qb10 are provided in the diffuser. The invention can not only supply oxygen according to the needs of patients, but also perform negative pressure suction treatment in the absence of a vacuum source.
Description
technical field [0001] The invention relates to a medical central oxygen supply and central suction system, in particular to an integrated module of oxygen inhalation and negative pressure suction. Background technique [0002] With the development of the medical industry, medical central oxygen supply and central suction systems have been gradually adopted by major hospitals, and secondary products such as oxygen inhalers and negative pressure regulators have been widely used to meet the oxygen supply between patients And negative pressure attracts demand. However, many regional hospitals are not equipped with conventional equipment for domestic second-level and above hospitals. In particular, negative pressure suction sources are rare in township and community hospitals, which not only delays the negative pressure suction treatment for patients, It has also indirectly led to the narrow application field of negative pressure suction and the low technical level of domestic ...
