Problems solved by technology

But there are still some deficiencies, mainly in: although the patient can maintain a certain airway pressure at the end of exhalation, the patient will encounter greater air pressure than normal exhalation at the beginning of exhalation, which is harmful to respiratory function. For injured patients, it undoubtedly increases a lot of pain

Embodiment 1

[0034] Such as figure 1 and 2 Shown: a mechanical PEEP valve for a medical emergency ventilator, which mainly includes a valve body 1, a movable flap mechanism and a control mechanism, and the valve body 1 has an exhalation channel 2. The movable flap mechanism is used to change the gas flow rate of the exhalation channel 2 of the valve body 1 . The control mechanism is used to control the movable shutter mechanism to perform intermittent actions.

[0035] Such as image 3 and 4As shown: the movable flap mechanism in this embodiment includes a circular flap 3, and the flap 3 is movably arranged in the exhalation passage 2 of the valve body 1 through its rotating shaft 4 along the radial direction, and one end of the rotating shaft 4 passes through the valve body. The side wall of body 1 is connected with the transmission assembly of the control mechanism. Driven by the control mechanism, the flap 3 switches between the initial state and the overturned state. In the initia...

Abstract

The invention relates to a mechanical PEEP valve of a medical first-aid breathing machine. The mechanical PEEP valve comprises a valve body, a movable blocking piece mechanism and a control mechanism,wherein the movable blocking piece mechanism comprises a round blocking piece; the blocking piece is arranged in an expiration channel of the valve body through a rotating shaft in the radial direction of the blocking piece; the blocking piece is driven by the control mechanism to be switched between the initial state and the turnover state; in the initial state, the blocking piece is parallel tothe axis direction of the expiration channel; in the turnover state, the blocking piece is perpendicular to the axis direction of the expiration channel; the control mechanism comprises a power source, a signal induction assembly and a transmission assembly; an airflow sensor is electrically connected with the power source through a control line; and the power source is in transmission connectionwith a rotating shaft in the movable blocking piece assembly through the transmission assembly. By means of the mechanical PEEP valve, smooth exhausting can be achieved without obstruction at the initial expiration stage of a patient, the flow of the expiration channel can be reduced at the later expiration stage, and therefore resistance is applied to expiration of the patient, the expiration time is prolonged, the oxygenation time is prolonged, and the oxygenation state is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mechanical PEEP valve of a medical emergency ventilator. Background technique [0002] Cardiopulmonary resuscitation is a first aid method used when spontaneous breathing stops. Air is rhythmically entered into the lungs by hand or mechanical devices, and then the air that enters the lungs is exhaled by using the elastic recoil force of the thorax and lung tissue, so as to replace self-breathing. The human heart and brain need to be continuously supplied with oxygen, and irreversible damage will be caused if the oxygen supply is interrupted for 3-4 minutes. Therefore, in some accidents, such as electric shock, drowning, cerebrovascular and cardiovascular accidents, once the heartbeat and breathing stop are found, the first rescue measure is to quickly perform artificial respiration and chest cardiac compression to maintain effective ventilation and blood circulation. ...
