Definitions

  • Humidification device and ventilation treatment device having the same
  • the ventilation therapy device supplies a positive pressure of breathable gas to the patient through a patient contact member such as a mask to assist the patient in breathing, treat the patient's respiratory disorder, and reduce respiratory effort.
  • the liquid inlet is provided at the bottom of the liquid storage chamber.
  • the vaporization device is disposed within the recess.
  • the air inlet of the humidification chamber includes an extension duct that protrudes into the humidification chamber, and the extension duct does not contact the liquid in the humidification chamber.
  • the humidifying device is a humidifying device for a ventilation therapy device.
  • the present invention also provides a ventilation therapy apparatus comprising a main body and a humidification device as described above, an air outlet of the main body being coupled to an intake port of the humidification chamber of the humidification device.
  • a person skilled in the art can provide a specific position where the communication device 130 is connected to the lower portion of the side wall of the liquid storage chamber 110 and the lower portion of the side wall of the humidification chamber 120 as needed. Further, since the amount of predetermined liquid that can stay in the humidification chamber 120 is small, it is also possible to prevent the liquid from flowing back from the intake port 121 of the humidification chamber 120 into the main body.
  • One end of the linkage rod 220 is coupled to the valve 210 and the other end is coupled to the handle.
  • the linkage lever 220 can be moved up and down.
  • the valve 210 closes the opening of the communication device 130, the communication device 130 is closed, and the liquid storage is closed.
  • the chamber 110 and the humidification chamber 120 form separate spaces, respectively.
  • the switching device can also have other structures. For example, when the liquid storage chamber 110 and the humidification chamber 120 are disposed at a certain distance apart, the switching device can be disposed as a rotary valve in the middle of the communication device 130.
  • the humidification chamber 420 may be disposed in the middle of the reservoir 410, that is, the reservoir 410 surrounds the humidification chamber 420. Since the humidification chamber 420 is isolated from the outside by the liquid storage chamber 410, the noise transmission can be effectively reduced.
  • the through hole When the through hole is rectangular, it may extend in the width direction of the side wall, i.e., a slit extending along the width of the side wall is formed at the bottom of the common side wall 401.
  • the common side wall 401 is an annular shape as shown in Fig. 4A, the through holes may be distributed along the annular common side wall 401, or may be an annular slit extending in the circumferential direction of the common side wall 401. It can be seen that the through hole can have any structure and shape as long as its function can be realized.
  • the humidification device provided by the present invention always works for a small portion of the liquid during the humidification process, thereby saving power consumption, avoiding waste, and accelerating the steam generation rate as compared with the existing humidification device. And because the amount of liquid in the humidification chamber is small, the risk of backflow of the liquid is reduced. Further, the liquid storage chamber and the humidification chamber of the present invention are separated, and the highest liquid level that can be used in the liquid storage chamber is the highest liquid level of the liquid storage chamber, thereby increasing the utilization space of the liquid storage chamber.
  • the drug sprayer 500 includes a reservoir 510, a humidification chamber 520, a communication device 530, and an atomization device 540.
  • the reservoir 510 is used to store a liquid containing the medications required by the patient.
  • the humidifying chamber 520 is provided with a vent port similar to the humidifying device for a medical humidifier described above, and the air inlet 121 and the air outlet 122 in Fig. 1 are combined into the same vent 521.
  • the communication device 530 is connected to the liquid chamber 510 and the humidification chamber 520 for supplying the liquid in the reservoir 510 to the humidification chamber 520.
  • the atomizing device 540 is used to atomize the liquid in the humidifying chamber 520.
  • the liquid storage chamber 510 is provided with a liquid inlet 511 and a sealing cover (not shown) that can cover the liquid inlet 511 to seal the liquid storage chamber 510.
  • the communication means 530 is connected between the lower portion of the side wall of the reservoir 510 and the lower portion of the side wall of the humidification chamber 520.
  • the inlet port is provided at the bottom of the reservoir.
  • the liquid inlet is provided at the top of the side of the reservoir provided with the communication means.
  • the communication device is provided with a pump for controlling the flow rate of the liquid from the reservoir to the humidification chamber.
  • the drug sprayer further comprises a switching device for opening and closing the communication device.

Abstract

La présente invention concerne un appareil d'humidification (100) et un appareil de thérapie de ventilation fourni avec celui-ci. L'appareil d'humidification (100) comprend une chambre de stockage de fluide (110) pour stocker un fluide ; une chambre d'humidification (120) avec une entrée d'air (121) et une sortie d'air (122) agencées sur celle-ci ; un dispositif de communication (130) pour raccorder la chambre de stockage de fluide (110) avec la chambre d'humidification (120) afin d'alimenter le fluide dans la chambre de stockage de fluide (110) dans la chambre d'humidification (120) ; et un dispositif de vaporisation (140) agencé sur la chambre d'humidification (120) pour vaporiser le fluide dans la chambre d'humidification (120), le fluide dans la chambre de stockage de fluide (110) étant empêché d'être alimenté dans la chambre d'humidification (120) lorsque le fluide dans la chambre d'humidification (120) atteint une quantité prédéterminée. L'appareil d'humidification (100) fonctionne toujours sur une petite partie du fluide dans le processus d'humidification et présente donc les avantages d'économiser la consommation d'énergie, d'éviter les pertes, d'accélérer la génération de vapeur, de réduire le risque de retour de fluide et d'augmenter l'utilisation d'espace de la chambre de stockage de fluide.
