How to tell whether the ventilator is second-hand?

Abstract: With the continuous improvement of people's living standards, many people will choose to buy household ventilator. Do you know anyone who is suitable for using a home ventilator? Generally speaking, people who snore and hold their breath while sleeping and people with cardiopulmonary insufficiency can use it. This is very effective for increasing lung ventilation, improving respiratory function, reducing respiratory consumption and saving heart reserve. However, although there are few fakes on the market, second-hand goods are rampant. How do we identify them? Let's take a look at the relevant knowledge of Bian Xiao! First, who is suitable for wearing a home ventilator?

1, snore and hold your breath (sleep apnea hypopnea syndrome)

Self-test criteria: daytime sleepiness, listlessness, lack of sleep at night, purple lips, snoring during sleep, memory loss, sexual dysfunction, short neck, small chin, patients with nasopharyngitis, obesity, etc. In case of the above phenomenon, please go to the respiratory department or otolaryngology department of the local 3A or above hospital for sleep monitoring and examination in time. The general cost is 500-600 yuan.

2. Patients with cardiopulmonary insufficiency and respiratory dysfunction (heart failure, respiratory failure, sleep apnea complicated with respiratory failure, motor nervous system diseases, etc.). )

Self-test standard: All patients diagnosed as chronic obstructive pulmonary disease, respiratory failure and weakened lung function need ventilator treatment.

Second, how to tell whether the household ventilator is second-hand?

Because of the high technology content, there are no fakes so far, but there are many second-hand ventilators, refurbished machines, repair machines and parallel ventilators on the market. So, how should we identify it?

First, check the working time of the ventilator. The working hours of the ventilator cannot be changed. Unlike a computer phone, it can be refreshed. The manufacturer will not allow the running time of the ventilator to be rewritten when developing and producing. There is a simple reason. If it can be rewritten, consumers can continue to enjoy the warranty and replacement service by modifying the time when the warranty period is approaching, right? Of course each brand is different.

Second, look at the appearance. Although the time cannot be changed, 0 hours does not mean that the machine is new, because the machine may be broken, and then the main version and turbine were changed when it was repaired. But fortunately, foreign manufacturers are very strict. Although they will sell new parts to repair shops, they will never provide anyone with a brand-new shell. Take Weikang ventilator as an example, you can look at the main machine. It must be at the bottom of the mainframe, under the bar code of the plastic label, with the production date of the machine. The whole label is plastic-sealed on the machine, and it is not allowed to be separated, pasted or not.

Thirdly, each brand of ventilator has a unique anti-counterfeiting query code, and genuine licensed ventilator can be queried and compared through the only official website of the manufacturer. However, some merchants have made a fuss about this issue, copying the anti-counterfeiting code of genuine licensed ventilator and sticking it on refurbished machines and parallel ventilator. This needs to be used in the identification skills taught to you earlier.

Fourth, by observing the after-sales service, we can distinguish whether it is genuine licensed goods, refurbished machines and parallel imports. All imported ventilators are sold in China with nationwide warranty after-sales service, but the latter two are not available. Therefore, merchants selling refurbished machines and parallel ventilators will tell you that they are very strong and do not need manufacturers to do after-sales. They do it for you themselves. Actually, it is not, mainly because once regular agents and manufacturers find quality problems, they will be prosecuted and severely punished.

Third, the disinfection method of household ventilator

When using a home ventilator, it is best to clean the mask once a day and the filter and pipeline once every three days. The cleaning method is as follows:

Machine surface: If there is no obvious stain on the machine surface, it can be wiped with clean water; If there are stains or blood stains, you can wipe them with chlorine-containing disinfectant.

Nose (face) mask: first wipe with 75% alcohol, and then wipe with water. Pipeline: soak in chlorine-containing disinfectant for 30 minutes, then rinse with flowing water and dry for later use.

Headband: After washing with detergent, rinse with clear water and dry for later use.
