Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a breathing machine filtering device. Background Art

[0002] As we all know, in modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used in respiratory failure caused by various causes, anesthesia and respiratory management during major surgery, respiratory support therapy, and emergency resuscitation. They occupy a very important position in the field of modern medicine. Ventilators are vital medical devices that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] At present, the filter elements used in ventilators are generally made of medical foam or dust removal filter media. After a period of use, a large amount of dust and bacteria adhere to the outer wall of the existing filter elements. During the process of replacing the filter element, the user needs to hold the filter element by hand. During the process of holding the filter element, the filter element is squeezed by the hand, and the filtered matter (dust, bacteria) on the outer wall of the filter element is easy to fall off, causing pollution to the environment and the hands, and easily causing cross infection. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a respirator filter device, which can effectively prevent the filter material on the filter core from falling off.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a respirator filtering device, comprising a mounting shell and a sealing cover, a filter core is mounted inside the mounting shell, an air inlet connector is provided on the top of the sealing cover, an air outlet connector is provided on the mounting shell, a storage groove with an open end is provided in the middle of the filter core, an insertion head connected to the air inlet connector is provided at the bottom of the sealing cover, a plurality of through holes are provided on the insertion head, the insertion head is inserted into the interior of the storage groove, a fixing plate is provided on the top of the filter core, and a through opening matching the insertion head is provided in the middle of the fixing plate.

[0008] Furthermore, the sealing cover is detachably mounted on the mounting housing.

[0009] Furthermore, a sealing ring is provided inside the through opening.

[0010] Furthermore, a plurality of holding rods are provided around the fixing plate.

[0011] Furthermore, anti-slip grooves are provided on the outer walls of the air inlet connector and the air outlet connector.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides a ventilator filter device with the following beneficial effects:

[0014] The filter device for a respirator is provided with a storage groove and an insertion head. The insertion head is inserted into the interior of the storage groove. The storage groove stores the filter material. The filter material is retained in the storage groove and will not adhere to the surface of the filter element. Therefore, the filter material is not easy to fall off. The user holds the fixing plate and the holding rod during the holding process. Therefore, the filter element will not be squeezed when replacing the filter element. This further avoids the filter material from falling off due to pinching, thereby effectively preventing the filter material from falling off and polluting the environment and the user's hands.
