Safe and countable quantitative medicine feeding actuator with buffer device

Abstract

The invention discloses a safe and countable quantitative medicine feeding actuator with a buffer device, which is characterized by comprising an actuator body, wherein a storage chamber storing a gallipot is disposed inside the actuator body, a medicine liquid nozzle mechanism connected to the gallipot is disposed on one end of the actuator body, and a rotary self-locking safety cover which can prevent accidental pressing of the gallipot inside the actuator body is disposed on the other end of the actuator body. The objective of the invention is to overcome defects in the prior art and provide the safe and countable quantitative medicine feeding actuator with the buffer device, which is simple in structure, convenient in use, safe and reliable.

Description

technical field [0001] The invention relates to a safety and countable dosing actuator with a buffer device. Background technique [0002] The metered dose aerosol actuator is an important part of the metered dose aerosol product, its main function is to carry the main body of the aerosol and open the valve of the aerosol, and at the same time open the contents of the drug according to the predetermined form It is sprayed into the throat of the mouth, and the drug particles of appropriate size directly act on the patient's lungs through the throat. [0003] Existing metered dose aerosol actuators generally include a main body carrying aerosol, and a nozzle at an angle to the main body is fixedly arranged at the front end of the main body. The existing design makes the lateral volume of the actuator relatively small. Large, inconvenient to carry, and the existing actuators are prone to mispressing accidents due to design defects. At the same time, the existing pharmaceutical...

[0003] Existing metered dose aerosol actuators generally include a main body carrying aerosol, and a nozzle at an angle to the main body is fixedly arranged at the front end of the main body. The existing design makes the lateral volume of the actuator relatively small. Large, inconvenient to carry, and the existing actuators are prone to mispressing accidents due to design defects. At the same time, the existing pharmaceutical aerosols have no counting function, and patients cannot predict the use of drugs when using the product amount and the remaining dose, which can easily lead to life-threatening or unnecessary trouble

For example, the appearance of traditional asthma spray cans cannot tell the amount of remaining medicine. If the patient has prepared multiple bottles of asthma spray cans, it can still solve the urgent need. If the patient does not prepare extra bottles of asthma spray cans, there is no one else around Once an asthma attack occurs, the patient may not be able to save himself by using the asthma spray can with no medicine in it, and is more likely to miss the prime time for emergency treatment, resulting in death accidents

[0004] When the existing actuator sprays medicine, the medicine liquid is sprayed directly from the nozzle, which often causes discomfort to the user due to the excessive impact force and the medicine will accumulate on the throat wall due to the excessive impact force and cannot enter the inside
