Example 1
This embodiment provides a continuous positive airway pressure device for single lung ventilation surgery, as shown in figures 1-3. The device comprises an air pressure diaphragm capsule and a three-way member 10 connected with the bottom of the air pressure diaphragm capsule; the air pressure diaphragm box comprises an air pressure diaphragm box cover 1 and an air pressure diaphragm box seat 2 which are in sealing connection, an elastic diaphragm 3 which divides the inner space of the air pressure diaphragm box into an upper space communicated with the atmosphere and a lower space communicated with the lung of a patient is arranged in the air pressure diaphragm box, as one implementation mode of the embodiment, the air pressure diaphragm box cover 1, the elastic diaphragm 3 and the air pressure diaphragm box seat 2 are three independent components, and the air pressure diaphragm box cover 1, the elastic diaphragm 3 and the air pressure diaphragm box seat 2 are bonded and sealed through a sealant 11 to form a main body structure of air pressure detection.
The elastic membrane 3 is provided with an indicator needle 4 which moves synchronously with the elastic membrane 3 to display the output air pressure value to the patient. The bottom of the indicator 4 may be fixed to the upper surface of the elastic film 3, for example, by being fixed to the elastic film 3 by adhesion, insertion, or the like.
The air pressure film box cover 1 is provided with an air pressure scale tube 12 for the indicator needle 4 to move up and down, and the air pressure scale tube 12 is provided with scale marks. As an implementation of the present embodiment, the indicator needle 4 is fixed at the center of the elastic membrane 3, and the air pressure gauge tube 12 is coaxial with the indicator needle 4. The top of the indicator needle 4 extends into the air pressure scale tube 12 and is movable up and down along the air pressure scale tube 12. The corresponding air pressure value can be read out according to the staff gauge 14 of the staff gauge pipe, so that the forward air pressure given to the lung of a patient can be accurately regulated, the phenomenon that the operation and the high air pressure damage of the lung are influenced by the expansion of the lung caused by too small air pressure and too large air pressure can be avoided, and the life safety of the patient is ensured.
The gas pressure diaphragm capsule seat 2 is provided with an oxygen outlet 7, a gas pressure regulating mechanism and a connecting port connected with a three-way member 10, and the three-way member 10 is provided with an oxygen inlet 6. Oxygen enters the air pressure diaphragm capsule seat 2 from the oxygen input port 6, is discharged from the oxygen output port 7, and is regulated by the air pressure regulating mechanism to achieve the effect of controlling the air pressure in the system.
The air pressure film box cover 1 is provided with an air pressure film box exhaust hole 13 communicated with the atmosphere. So that the upper side of the elastic membrane 3 is vented to the atmosphere. Therefore, when a positive pressure greater than atmospheric pressure occurs below the elastic membrane 3, deformation of the elastic membrane 3 is caused, and this deformation causes up-and-down movement of the indicator needle 4 bonded to the elastic membrane 3 through the silica gel 5, thereby realizing visual output of the air pressure.
Fig. 3 to 4 are schematic structural views of the air pressure adjusting mechanism. The air pressure regulating mechanism comprises an air pressure regulating tube 19 communicated with the air pressure bellows seat 2, the inside of the air pressure regulating tube 19 is hollow, an air vent 20 is arranged on the air pressure bellows seat 2, the air pressure regulating tube 19 is in air communication with the air pressure bellows seat 2 through the air vent 20, the side wall of the air pressure regulating tube 19 is provided with a pressure regulating exhaust hole 17, and an air pressure regulating knob 16 for controlling the air vent 20 to open and close is arranged in the air pressure regulating tube 19. As an implementation of this embodiment, the air pressure adjusting knob 16 is screwed with the air pressure adjusting tube.
The air pressure adjusting knob 16 is moved to control the air exhausting smoothness of the vent hole through the pressure adjusting vent hole 17, so that the effect of controlling the air pressure in the system is achieved. When the air pressure regulating knob is used, the air pressure regulating knob 16 is rotated outwards, so that the ventilation hole and the pressure regulating exhaust hole 17 reach the maximum exhaust smoothness, and the air pressure in the system is the lowest. Then, according to the patient's condition, the air pressure adjusting knob 16 is rotated and moved slowly inwards to increase the exhaust resistance of the exhaust hole A and the pressure adjusting exhaust hole 17, so that the air pressure in the system and the air pressure of the output port are increased slowly, when the expected air pressure is reached, the movement of the air pressure adjusting knob 16 is stopped, and at the moment, the air pressure in the system is constant and the appointed air pressure is output to the lung of the patient through the output port.
The application method of the invention comprises the following steps: oxygen with certain flow (0-10L/min) is communicated with the oxygen input port 6, the oxygen output port 7 at the output end is communicated with the tracheal intubation of a patient, and the internal air pressure of the system is regulated by changing the exhaust smoothness degree through the regulating air pressure regulating knob 16, so that the oxygen output air pressure of the oxygen output port 7 is regulated, and the effect of outputting positive air pressure to the lung of the patient is realized. At the same time, the output air pressure causes the pointer to move up and down through the deformation of the elastic membrane 3, and the value of the positive air pressure can be read out through the scale tube scale 14.
Example 2
The present embodiment provides a continuous positive airway pressure device for single lung ventilation surgery, which has the same structure as that of embodiment 1, except that the first connecting port of the three-way member 10 is connected with the bellows seat 2, the second connecting port is connected with the air inlet conduit 8 as the oxygen inlet 6, and the third connecting port is connected with the elastic air bag 18. The air pressure inside the system may be conducted to the elastic balloon 18. The elastic air bag 18 can enable a doctor to sense the air pressure in the system, avoid injuries caused by excessive air pressure, and can achieve the effect of expanding the lung to assist operation by pressing the air bag.
When the pressure regulating knob 16 is regulated to gradually increase the output air pressure of the oxygen output port 7, the pressure can be transmitted to the elastic air bag 18 through the three-way component 10 at the moment, so that the elastic air bag 18 is gradually expanded, when the air pressure in the elastic air bag 18 is equal to the output air pressure, the expansion of the elastic air bag 18 is stopped, the expansion degree of the elastic air bag 18 and the pressure in the elastic air bag 18 can be visually observed, the pressure in the finger touch sense is sensed, adverse effects caused by overlarge air pressure are avoided, and the safety coefficient of a patient is increased.
Another effect of the flexible bladder 18 is that when the surgeon needs to inflate the lungs for operation, he or she can quickly press the bladder by hand to increase the pressure within the system, thereby increasing the pressure output from the oxygen output port 7 to the lungs and inflating the patient's lungs to assist in the surgical procedure. Similarly, when the surgeon no longer needs to inflate the lungs, the anesthesiologist stops pressing on the elastic balloon 18 and the output air pressure is gradually reduced to the original set air pressure, facilitating further surgical procedures by the surgeon.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
