- Patent Document 1 Japanese Patent Laid-Open No. 2 0 2-2 1 9 1 7 5 Disclosure of Invention
- the conventional sputum suction device 100 has the following drawbacks. (1) In the case of a heavy patient, positive pressure (positive expiratory pressure) is always applied to expand the lungs. In the soot suction device 100, an intake valve 10 07 and an exhaust valve 10 8 are arranged in a negative pressure casing 10 3. Therefore, for example, even in a respirator that employs a closed suction system (CCS) that draws sputum without removing the respiratory tube from the tracheal force neure, positive pressure is effective. As a result, a part of the air in the trachea may be exhausted to the outside through the suction tubes, the collection bottles 10 9 and the double valves 1 0 7 and 1 0 8 of the soot suction device 100. As a result, the airway pressure in the human respiratory system fluctuated, adversely affecting the patient. '

In other words, it was not possible to treat the tracheal sputum while continuing the artificial respiration.
- the inventor paid attention to a tube pump that can pump liquid without using a valve as a sputum suction device suitable for a CCS type artificial respiration equipment. This is because the roller attached to the rotor closes a part of the tube and moves the closing position on the tube continuously to the liquid discharge side to force the liquid in the tube. To extrude.

- the suction pressure of the tube pump 16A may be increased or the auxiliary pump 16B may be operated at regular intervals by timer control.
- the tube pump 16A When the power is turned on and the control circuit is started (S1 0 1), the tube pump 16A is activated and the soot suction starts (S10 02). Next, it is determined whether the suction pressure of the tube pump 16A has increased (S103). If it is rising, go to S1 04, otherwise go back to S1 03. In S1 04, it is determined whether the suction pressure of the tube pump 16A is less than the set value. If less than the set value, proceed to S105. Here, the number of rotations per unit time of the output shaft of the motor of the tube pump 16A is increased to increase the suction amount of the soot, or the auxiliary pump 16B is operated. Next, the timer determines whether 15 seconds have passed (S1 06).

After elapse, the timer is turned off and the suction pressure of the tube pump 1 6 A Return to the value during normal operation, or stop the operation of auxiliary pump 16 B and switch to normal operation (S 1 0 7). Then, the process returns to S 1 0 3.
- soot suction device 16 As another suction control method for soot by the soot suction device 16, for example, when the suction pressure is rising, the output of the tube pump 16 A is increased until the suction pressure reaches a predetermined operation switching value. The operation may be switched to the auxiliary pump 16 B only when the suction pressure increases until the tube pump 16 A can no longer handle it. As a result, it is possible to perform soot suction treatment according to soot amount or soot viscosity.
- soot suction control method using the soot suction device 16 for example, a method of providing a low set value and a high set value may be employed. Specifically, for example, the current output (suction force) of the tube pump 16 A is maintained until the low set value is reached. Also, between the low set value and the high set value, the suction force of the tube pump 16 A is controlled according to the magnitude of the detected value. Then, if the high setpoint is reached, activate auxiliary pump 1 6 B. Even if it controls in this way, the suction

- the human respiratory system 10 B to which the endotracheal suction device according to the third embodiment of the present invention is applied is based on the detection signal from the pressure sensor 31 in the second embodiment.
- the pressure sensor 31 detects it, and the control unit 18 increases the output of the tube pump 16 A based on the detection signal. Further, if the soot suction pressure decreases, the pressure sensor 31 detects this, and the control unit 18 reduces the output of the tube pump 16 A based on the detection signal.
- the suction control of sputum using the pressure sensor 3 1 is possible, while the number of parts of the artificial respiration system 1 O A is reduced compared to the first embodiment, and the cost can be reduced.
- Example 4 Other configurations, operations, and effects are the same as those in the first embodiment, and thus description thereof is omitted.
- Example 4
- the endotracheal fistula suction device 1 60 according to the fourth embodiment of the present invention is the same as the second embodiment except that the ventilator 1 2 is removed and the tracheal force has a double-pipe structure.
- a single-pipe tracheal force neural tube 14 A is used instead of the pneumatic tube 14, and the suction tube 15 is directly passed through the tracheal force neural tube 14 A. Therefore, the respiratory tube 1 1, the mount 2 0 and the exhalation valve 2 1 attached to the ventilator 1 2 are omitted.
- the soot film F may be intermittently generated by the surface tension in the suction tube 15 and the tracheal force nucleus 14 A. In this way, it tends to occur when a small amount of soot is constantly generated within 1 3.
- These membranes F can be If you try to remove it with a diaphragm-type soot suction device, the membrane F will be broken by the high suction pressure, and these soot cannot be sucked well.
- the tube pump 16 A capable of low-speed suction of soot, these membranes F can be continuously sucked out without breaking.
- the effect of removing the membrane F by suction is not limited to the fourth embodiment, but is an effect of the present invention using a tube pump.
- Example 5 Other configurations, operations, and effects are the same as those in the first embodiment, and thus description thereof is omitted.
- the endotracheal fistula suction device 1 6 OA is the tube pump 1 6 A based on the detection signal from the pressure sensor 3 1 in Embodiment 4.
- the alarm means 1 6 1 makes an alarm sound and a nurse call. This is an example.
