Problems solved by technology

[0003] The traditional aerosolizer uses a piston pump to fix the dose of medicine taken at one time. If the seal between the piston pump and the piston seat is not good for the liquid medicine, not only the medicine dose cannot be fixed, but it may also affect the spraying effect. The effect of mist

Abstract

The invention provides a fluid conveying device, which has a first piston seat, a second piston seat, a fluid conveying pipe and a seal. The first piston seat has a first communicating hole and a first connecting portion, and the first connecting portion defines an accommodating space and a communicating buffer space. The second piston seat has a second communication hole and a second connecting portion, and at least part of the second connecting portion is disposed in the accommodating space. The fluid delivery tube is accommodated in the first communication hole and the second communication hole, and is movably located between the first position and the second position. The sealing element is sleeved on the outside of the fluid delivery pipe. When the fluid delivery pipe is at the first position, the sealing element is located in the accommodating space. When the fluid delivery tube is at the second position, part of the sealing element is located in the accommodating space, and part of the sealing element is located in the accommodating space. The seals are located in the buffer space.

Description

【Technical field】 [0001] The present invention relates to a fluid delivery device, in particular, the present invention relates to a fluid delivery device for delivering medicinal liquid. 【Background technique】 [0002] Aerosolizer, also known as Nebulizer or Atomizer, is used to allow patients to inhale medicine. In particular, the liquid medicine will be decomposed into an aerosol with tiny particles or liquid droplets, so that the patients who use the medicine can obtain more efficient inhalation and absorption efficiency. The size of the above-mentioned tiny particles can be adjusted according to different respiratory conditions, such as chronic obstructive pulmonary disease (Chronic Obstructive Pulmonary Disease, COPD), asthma, or depending on the demand of the liquid medicine itself. Furthermore, it is also very important that patients receive the same dosage in each treatment modality. In other words, an aerosolizer needs to be able to deliver a fixed dose of medica...
