Description

Atomizing mist suction filter

technical field

The utility model relates to the field of hospital supplies, in particular to an atomized mist suction filter suitable for patients infected with multidrug-resistant bacteria.

Background technique

During nebulization treatment, the liquid medicine becomes mist under the action of gas and ultrasound, which is inhaled by the patient into the respiratory tract. During nebulization treatment for ordinary patients, the uninhaled nebulized liquid medicine mixes with the patient's exhaled gas and is discharged into the air to form an aerosol, which has no adverse effects.

Multidrug-resistant bacteria refer to bacteria that are resistant to three or more commonly used antibacterial drugs that are usually sensitive. Patients infected with multidrug-resistant bacteria are more difficult to treat, and the medical expenses and mortality rate will be significantly increased. Patients infected with multidrug-resistant bacteria usually need to be treated in isolation. In order to avoid the spread of multidrug-resistant bacteria, patients use wearable masks to filter their exhaled gas and then discharge it into the air.

However, patients infected with multidrug-resistant bacteria undergo nebulization treatment. Because they need to wear nebulization masks, they cannot wear masks. Bacteria spread.

ZL202120102103.4 discloses a face mask that reduces the spread of aerosols during aerosol inhalation by patients with multidrug-resistant bacteria. The special design of the mask can improve the fit and sealing effect with the patient's face, and an exhaust pipe is set up, which is intended to prevent the patient's exhaled gas from spreading randomly, ensure that the patient's exhaled gas is discharged from the exhaust pipe in a directional manner, and prevent drug-resistant bacteria from being infected by the patient. Inhalation can cause secondary infection. However, even if the mask is worn, the gas discharged by the patient's breathing is still discharged into the air together with the aerosolized medicinal liquid, which does not prevent the spread of multidrug-resistant bacteria.

Patients are usually nebulized sitting up or in a semi-recumbent position. The utility model is placed on the platform next to the patient (for example on the medical bedside table next to the hospital bed), by moving the utility model, the telescopic vertical rod 2, the rotation cross bar 3 and the direction of the suction cover 41 can be adjusted to make the suction cover 41 Close to the nebulizing mask. When nebulization, the patient's exhaled gas and the uninhaled nebulized medicinal liquid are discharged from the mask together, then are sucked into the suction cover 41, and then pass through the filter plate 42, which filters out aerosols and bacteria, so the utility model has the function of avoiding fog Beneficial effects of multidrug-resistant bacteria spread over time.

After the patient is atomized, as shown in Figure 3, by rotating the crossbar 3, telescopic upright bar 2 and adjusting the direction of the suction cover 41, the suction cover 41 can be covered on the ultraviolet sterilizing device 5, and then the ultraviolet sterilizing device 5 is opened. The suction hood 41 can be sterilized. After sterilization, the utility model can be stored and used again. This can prevent the utility model from carrying and spreading germs, and is also beneficial to avoiding the spread of multidrug-resistant bacteria.

In order to ensure that the utility model is placed stably, the base 1 should have a suitable weight. The weight of the suction purification device 4 of the present utility model is not large, so the base 1 does not need to be too heavy. The vertical rod 2 is telescopic and can be used to adjust the height of the suction purification device 4 , and also facilitates the suction cover 41 to be covered on the ultraviolet sterilizing device 5 . Ultraviolet sterilizing device 5 is a device that utilizes ultraviolet sterilizing lamp 52 to sterilize. Although it is simple and practical, ultraviolet rays are harmful to the human body. Therefore, the utility model adopts the method that suction cover 41 is covered on ultraviolet sterilizing device 5 to sterilize. 52 is shaded, thereby avoiding its disadvantages.

The concrete structure of suction purification device 4 is preferably as follows: suction cover 41 comprises square part 411, hollow fixed plate 412 and hollow gasket 413, has filter plate slit 414 on a side of square part 411, and the quantity of hollow fixed plate 412 is Two, the hollow fixed plate 412 is located in the square part 411 and connected with the square part 411, the two hollow fixed plates 412 are respectively located above and below the filter plate slit 414, the hollow gasket 413 is connected with the hollow fixed plate 412; the filter plate 42 It includes a filter plate outer frame 421 and a filter sheet 422 arranged in the filter plate outer frame 421; the filter plate 42 is inserted into the square part 411 from the filter plate slit 414, the filter plate outer frame 421 is bonded to the hollow gasket 413, and the filter plate outer frame 421 exposes the square portion 411 .

The significance of adopting the above setting is that it is convenient to replace the filter plate 42 . The filter plate 42 can be pulled out by directly holding the part of the filter plate outer frame 421 exposed from the square part 411 , and then pulling it out. The installation can be easily completed by inserting a new filter plate 42 , so the filter plate 42 can be replaced conveniently.

The filter sheet 422 can refer to the structure of the N95 mask, that is, the filter sheet 422 includes a cold contact rubber cotton filter layer, an activated carbon filter layer and a hot contact rubber cotton filter layer arranged in sequence. Of course, other designs of sheet-shaped filter structures can also be adopted.

Further, preferably, the suction cover 41 includes a shielding cover 46 , which is hinged to the square part 411 , and the shielding cover 46 shields the filter plate slit 414 after the filter plate 42 is pulled out. The meaning of such setting is that after the filter plate 42 is pulled out, the shielding cover 46 can still close the suction cover 41, which is beneficial to carry out ultraviolet sterilization.

The ultraviolet sterilizing device 5 should be powered and used, and can be powered by a plug-inserted operation.

As mentioned above, ultraviolet rays are harmful to the human body. The meaning of the above setting is that only when the suction cover 41 is covered on the lamp jacket 51 and the second switch 54 is pressed, the ultraviolet germicidal lamp 52 can be turned on, so as to avoid the accidental opening of the ultraviolet germicidal lamp 52 from affecting the outside world.

As mentioned above, the suction cover 41 needs to be able to adjust its direction so as to face the atomizing mask and cover the ultraviolet sterilizing device 5 . The specific manner may be that the suction cover 41 is connected with the cross bar 3 through a ball joint structure.

The function of the suction structure 43 is to provide a negative pressure to generate a suction effect. The suction structure 43 may be a negative pressure tube connector. In this way, use the pipeline to connect the negative pressure system of the hospital center and the connector of the negative pressure tube, and turn on the negative pressure system of the hospital center to generate the suction effect. The suction structure 43 can also be a blower.

In order to further facilitate the adjustment of the position of the suction and purification device 4, it is preferable that the cross bar 3 is telescopic. The telescopic bar is a conventional technology, and the specific structure of the telescoping of the cross bar 3 and the vertical bar 2 can refer to the prior art.
