Description

Technical Field

[0001] The present application relates to medical care instruments, and in particular to a nasal aspirator suction head and a nasal aspirator. Background Art

[0002] A nasal aspirator is a device used to suck out nasal secretions. It is usually used when infants and young children have nasal congestion and cannot expel nasal secretions. The nasal aspirators currently on the market use an air pump inside the body to suck out secretions, which creates negative pressure and sucks away secretions. However, secretions often enter the trachea inside the body, which is inconvenient for users to clean. Moreover, when users do not clean in time, the secretions will dry and harden and block the pipe. The existing isolated nasal aspirator can separate the snot from the body of the nasal aspirator, so that secretions cannot enter the body, which can ensure that the airway inside the body is not blocked and is also convenient for users to clean. However, the existing airbag isolated nasal aspirator suction head can only rely on the negative pressure accumulated in the body to instantly inhale and shrink, so that negative pressure is generated in the storage cavity to suck out the snot. A negative pressure chamber must be set in the body of the nasal aspirator, which has a complex structure and a large body. At the same time, the nasal aspirator suction head that cooperates with the body of the nasal aspirator cannot be directly inflated. Summary of the invention

[0052] Embodiment 2:

[0053] like Figure 7 , Figure 8 As shown, the nasal aspirator provided in the embodiment of the present application includes a nasal aspirator body and the nasal aspirator suction head in Example 1, the nasal aspirator suction head is arranged on the nasal aspirator body, and may include a body shell 500, a power supply 600, a solenoid valve 700, a positive pressure pump 800 and a control device, the body shell 500 is provided with an airbag air inlet 510, the airbag air inlet 510 cooperates with the nasal aspirator suction head, the power supply 600, the solenoid valve 700 and the positive pressure pump 800 are all arranged in the body shell 500.

[0054] The power supply 600 is used for supplying power, and the power supply 600 is electrically connected to the solenoid valve 700, the positive pressure pump 800 and the control device respectively. In one embodiment, the power supply 600 can be a battery.

[0055] A positive pressure pump 800, including a positive pressure pump air outlet 810;

[0056] The solenoid valve 700 may include a first solenoid valve connection port 710, a second solenoid valve connection port 720 and a third solenoid valve connection port 730, the positive pressure pump air outlet 810 is connected to the third solenoid valve connection port 730, the second solenoid valve connection port 720 is connected to the second channel, and the first solenoid valve connection port is connected to the atmosphere;

[0057] The control device is used to electrically connect to the positive pressure pump 800 and the solenoid valve 700 respectively, so that when the solenoid valve is in a working state, the second connection port 720 of the solenoid valve is connected to the third connection port 730 of the solenoid valve, and when it is not in a working state, the second connection port 720 of the solenoid valve is connected to the first connection port 710 of the solenoid valve.

[0058] The nasal aspirator provided in the embodiment of the present application has the following working process: the positive pressure pump outlet 810 outputs gas, which passes through the third connection port 730 of the solenoid valve, the second connection port 720 of the solenoid valve and the air inlet 510 of the airbag in sequence, and finally enters the airbag cavity 240, so that the airbag 310 slowly expands. When the airbag 310 expands to the required degree, the solenoid valve 700 starts to work, and the gas in the airbag 310 is quickly discharged through the second connection port 720 of the solenoid valve and the first connection port 710 of the solenoid valve in sequence. Since the first connection port 710 of the solenoid valve is connected to the atmosphere, the airbag 310 contracts rapidly, so that negative pressure is quickly generated in the storage cavity 230, and the snot is sucked in through the first channel 110 of the suction terminal 100 and stored in the storage cavity 230.

[0059] The nasal aspirator provided in the embodiment of the present application has no negative pressure chamber provided on the body of the nasal aspirator, and the gas outputted from the positive pressure pump outlet 810 directly passes through the third connection port 730 of the solenoid valve, the second connection port 720 of the solenoid valve and the air inlet 510 of the airbag in sequence, and finally enters the airbag cavity 240. The airbag 310 expands and then contracts, so that negative pressure is generated in the storage cavity, and secretions such as nasal mucus are sucked into the storage cavity for storage. The present application integrates the storage cavity and the negative pressure cavity into one, and the inflated airbag instantly releases positive pressure and generates negative pressure in the storage cavity. This not only simplifies the structure of the nasal aspirator, but also because the storage cavity is instantly converted from normal atmospheric pressure to negative pressure, nasal secretions such as nasal mucus can be quickly aspirated, thereby improving the user experience.

[0060] The above contents are further detailed descriptions of the present application in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions.
