Problems solved by technology

[0006] Although the above-mentioned method can solve the problem that the air pressure is too high at the beginning of exhalation and brings discomfort to the patient, there are still great defects:
[0009] Therefore, there is a need for a better solution in this field, which can better solve the problem that the air pressure is too high for the patient when the exhalation begins and it is easy to cause excessive exhalation

Embodiment 1

[0034] refer to figure 1, the present embodiment provides a kind of breathing apparatus, and this breathing apparatus comprises exhalation mouth, PEEP control unit 2 and negative pressure device, and exhalation mouth is used for receiving the exhalation of patient 1, and PEEP control unit 2 is optionally connected with exhalation mouth connected, the negative pressure device is connected in parallel with the PEEP control unit 2. Wherein, the exhalation port refers to the port that receives exhalation when the patient exhales, but it is not limited to only this function, and can also be used as an inhalation port or a sputum discharge port at the same time.

[0035] Specifically, the negative pressure device includes a pressure-adjustable first sealed chamber 3, and the first sealed chamber 3 is selectively communicated with the exhalation port. The first sealed volume 3 can communicate with the exhalation port before the PEEP control unit 2 to receive the exhalation of the pa...

Embodiment 2

[0081] The difference between this embodiment and Embodiment 1 is that the structures of the separator 34 and the housing 33 are different, as follows:

[0082] refer to figure 2 , the casing 33 is a closed cylinder, and two partitions 34 are provided, which are respectively a first partition 341 and a second partition 342, and the first partition 341 and the second partition 342 divide the casing 33 into independent parts. Two chambers, namely the first sealed volume 3 and the auxiliary first sealed volume 3'.

[0083] Wherein, the first partition 341 and the second partition 342 are fixedly connected at the central axis of the casing 33, the first partition 341 is fixedly connected with the casing 33, the second partition 342 is slidably connected with the casing 33 and The second partition 342 can rotate around the central axis of the housing 33 . The driver 37 is connected to the second partition 342 and can drive the second partition 342 to rotate along the central axi...

Abstract

The invention relates to breathing equipment. The breathing equipment comprises an exhalation opening, a PEEP control unit and a negative pressure device, wherein the exhalation opening receives exhalation, the PEEP control unit is selectively communicated with the exhalation opening, and the negative pressure device is connected with the PEEP control unit in parallel. The negative pressure devicecomprises an adjustable-pressure first seal containing cavity, the first seal containing cavity is selectively communicated with the exhalation opening, and then can receive exhalation in prior to the PEEP control unit, initial pressure in the first seal containing cavity is increased to the preset maximum pressure because exhalation is received, and it is switched that the PEEP control unit is communicated with the exhalation opening to receive the exhalation of a patient. When the first seal containing cavity is disconnected from the exhalation opening, the pressure of the first seal containing cavity is adjusted to the initial pressure. The preset maximum pressure is smaller than or equal to the PEEP value of the PEEP control unit. With the breathing equipment, excessive exhalation canbe prevented, and meanwhile the demand for comfort when the patient starts to exhale can be met.

Description

technical field [0001] The invention belongs to the medical and health field, and in particular relates to a breathing apparatus. Background technique [0002] Respiratory equipment is one of the most critical means to save the lives of emergency and critical patients. When the respiratory equipment is ventilated spontaneously, the inspiratory action produces positive thoracic pressure, and the passive expansion of the lungs produces alveoli and positive airway pressure, which constitutes the pressure between the airway opening and the alveoli. After inhalation, the thorax and lungs elastically retract, producing the opposite pressure difference to complete exhalation. Therefore, it has become an indispensable device in clinical treatment, and it is becoming more and more widely used in the fields of first aid, anesthesia, ICU and respiratory therapy. [0003] The most typical respiratory equipment is the ventilator. The ventilator is widely used in clinical medicine. It is...
