Precautions for the use of the aspirator, and what should be paid attention to before using the aspi

1) The voltage used in the suction device should be consistent with the power supply voltage, otherwise it is easy to damage the motor and affect the suction power.

2) The sputum suction action should be light and steady. The suctioning time should not exceed 15 seconds at a time, and the continuous use time of the suction device should not exceed 3 minutes.

3) **Tank **Towel is changed and disinfected once a day, and the sputum suction tube is replaced and used every time.

4) The aspirated liquid in the reservoir bottle should be poured in time, and should not exceed 2 3 of the bottle, so as to avoid sputum inhalation into the motor and damage the machine. After the reservoir bottle is washed, a small amount of water should be filled to prevent sputum from sticking to the bottom of the bottle and hindering cleaning.

5) Dedicated custody, regular inspection and maintenance, to maintain its good performance.

1.How do I check if the suction device is performing well?

Connect the suction device to the power supply, turn on the switch, check whether the catheter connected to the suction device is correct, whether the suction is normal, and adjust the negative pressure according to the patient's condition and sputum viscosity (40, test the suction with isotonic saline to check whether the catheter is unobstructed. The catheter is unobstructed and the suction power is good and can be used.

2.What should I do if there is resistance or difficulty in suctioning? What should I pay attention to when suctioning sputum for children?

When encountering resistance, do not insert strongly, and when it is not easy to suck out phlegm, you can drop a small amount of phlegm-reducing liquid such as A-chymotrypsin and knock on the back, and promote the sputum aspiration through gentle vibration, or use ultrasonic nebulization inhalation to make the sputum thin and sucked out.

3.How to control the time of suction?

When suctioning sputum for the patient, the action should be gentle, lifting from the deep part upward, rotating left and right, and sucking the sputum clean. The sputum aspiration time should not exceed 15 seconds each time, so as to avoid hypoxia of the patient, and those with severe hypoxia should be given oxygen after suctioning.

4.What to look for when suctioning?

Suction deviceDuring the sputum suction, pay attention to the changes in the patient's breathing before and after suction, whether there is any hypoxia manifestation, observe the color, quantity and odor, nature and viscosity of the sputum suction, and observe whether the oral mucosa is damaged and the general condition of the patient, and make a record.

5.What are the signs of cardiac arrest?

Sudden loss of consciousness, convulsions or coma, loss of carotid arteries, arrest of breathing, dilated pupils, pallor or bruising.

Recognize it, learn it, master it.

How to use the suction device.

The principle of the suction device is very simple, that is, the negative pressure state of the suction head is a negative pressure state carried out by a certain method, and the atmospheric pressure will squeeze the material outside the suction head to the suction head, so as to achieve"Attract"effect. Regardless of the type of aspirator, the principle is more or less the same. Over the years, many different types of attractors have emerged.

According to the different power sources, it can generally be divided into independent electric suction device and centralized control suction device.

Electric suction device: Electric suction device has been widely used in small and medium-sized hospitals because of its use of electrical energy as the power source, because it has the characteristics of high power, strong suction, wide range of application, and good mobility.

Electric suction devices are divided into three types according to their use: ordinary electric suction devices, abortion electric suction devices and gastric lavage electric suction devices.

1。The ordinary electric suction device is specially used for blood suction, water, pus, sputum, etc., and cannot be used for others.

2。An abortion electric suction device is a type of suction device (i.e., suction of the uterus) that is specifically used for abortion. Compared to other types of electric suction devices, this suction device has two differences:

One is two 5000 ml gas cylinders and the other is two 500 ml liquid bottles; The other is that it has a negative pressure automatic control part for maintaining the set negative pressure range.

3。Gastric lavageElectric aspirator

The device is specifically designed for gastric lavage. The structure of this suction device is to use the positive and negative pressure of the vacuum pump. It has both positive and negative pressure indicators.

It uses a special knob switch to control the switching between positive and negative pressure. In addition, it has a positive and negative pressure control valve. At present, the new gastric lavage machine is equipped with positive pressure, negative pressure manual and automatic control functions, which is not easy to clog and is very suitable for clinical emergency use.

Depending on the type of vacuum pump used, there are two types of electric suction devices:

1。One is a sliding vane vacuum pump. There is oil in this vacuum pump. It is mechanically noisy. When the vacuum pump oil storage chamber is oil-free or the oil level is too low, or the oil ring does not rotate, the vacuum pump cannot be lubricated, and the vacuum pump is easy to burn out.

2。The other is a diaphragm vacuum pump. That is, the vacuum pump is oil-free.

It operates quietly and usually does not require more maintenance. In the membrane electro-electric suction device, there is also a negative pressure suction device with electromagnetic structure. This suction device also uses a diaphragm to control the intake and exhaust of the vacuum pump to achieve the purpose of negative pressure suction.

Maintenance of the suction device.

1.Level 1 maintenance.

To clean the overflow protection cup, first take out the medical protection cup from the negative pressure straw, then take out the protective cup, take out the float, seal the valve seat, clean the disinfection parts with 84 disinfectant, and finally clean it with clean water.

The relevant pipes and waste liquid barrels are cleaned and disinfected with 84 disinfectant, and finally cleaned with clean water.

After disinfection, adjust the switch to the "off" device, rotate the adjustment knob counterclockwise to zero, and place it in a well-ventilated environment, the residual disinfectant volatilizes to avoid dripping;

The suction device is a national legal measurement tool, which should be calibrated regularly in accordance with relevant national regulations.

2.Level 2 maintenance.

The medical device department conducts performance tests on the vacuum suction device every six months, and if problems are found, preventive maintenance is carried out in a timely manner. Sman PeakSuction device**Reasonable operation, simple and cost-effective, worry-free after-sales.
