Embodiment 1

[0042] Such as figure 1 , 13 As shown, an artificial nose for respiratory intubation includes a filter assembly 1, the filter assembly 1 includes a first filter component 11, and the first filter component 11 is formed by sealingly connecting the filter membrane 2 in the connection area, and the filter Diaphragm 2 is specifically composed of three layers of spunbonded nonwoven fabric, meltblown nonwoven fabric and spunbonded nonwoven fabric. It has good filtering effect and has sufficient strength and wear resistance. The membrane material is made of polypropylene , Specifically, it can filter particulate matter with a kinetic equivalent diameter of less than or equal to 2.5 microns in the atmosphere, that is, PM2.5. After a piece of filter membrane 2 is folded in half, the unconnected area is sealed and connected by an ultrasonic welding process. The inner cavity wrapped by the filter membrane 2 formed after the seal connection is the inner cavity 21 of the filter element. I...

Embodiment 2

[0047] Such as Figure 5 As shown, an artificial nose for respiratory intubation includes a filter assembly 1 and a housing 3, the inner hollow 31 of the housing 3 is used to accommodate the above filter assembly 1, and the housing 3 is provided with an air inlet 32 ​​and an outlet. Air port 33, the filter assembly 1 includes a first filter component 11, the first filter component 11 is formed by sealing and connecting the filter membrane 2 in the connection area, and the filter membrane 2 is specifically made of spunbonded non-woven fabric, melt-blown non-woven fabric It is composed of three layers of woven fabric and spunbonded non-woven fabric. It has good filtering effect and sufficient strength and wear resistance. The membrane material is made of polypropylene fiber, which can specifically filter the air with a dynamic equivalent diameter of less than or equal to 2.5 Micron particulate matter, namely PM2.5. The filter membrane 2 is hermetically connected using an ultras...

Embodiment 3

[0057] Such as Figure 11 , 12 , 13, an artificial nose for respiratory intubation, including a filter assembly 1 and a housing 3, the inner hollow 31 of the housing 3 is used to accommodate the above-mentioned filter assembly 1, and the housing 3 is provided with an air inlet 32 and an air outlet 33, the filter assembly 1 includes a first filter component 11, a second filter component 12, and an intermediate filter component 13, the first filter component 11 is formed by a filter membrane 2 sealed in the connection area, and the filter membrane Sheet 2 is specifically composed of three layers of spunbonded nonwoven fabric, meltblown nonwoven fabric, and spunbonded nonwoven fabric. It has good filtering effect and has sufficient strength and wear resistance. The membrane material is made of polypropylene. Specifically, it can filter particulate matter with a kinetic equivalent diameter less than or equal to 2.5 microns in the atmosphere, namely PM2.5. The filter membrane 2 i...

Abstract

The utility model provides an artificial nose for a breathing intubation tube. The artificial nose for the breathing intubation tube comprises a shell and a filter assembly, wherein the filter assembly comprises a first filter component which is formed by connecting a filter membrane in a sealing mode, an internal cavity formed through wrapping is an inner cavity of the filter component, a first filter component opening is formed in the filter membrane of the first filter component, one end of the first filter component opening is communicated with the inner cavity of the filter component, and the other end of the first filter component opening is communicated with a human body tracheostoma or the breathing intubation tube. According to the artificial nose, the filter area is increased to the maximum in a limited space, the filter effect of stopping bacteria and viruses is achieved, breathing resistance is reduced, the function of heating and humidifying external gas is further achieved, and gas suitable for being inhaled can be supplied to the human body.

Description

technical field [0001] The invention relates to an artificial nose for respiratory intubation, which is used for air filtration of artificial respiration airway, and belongs to the technical field of medical equipment manufacturing. Background technique [0002] Endotracheal intubation has been used clinically for a long time. It is necessary to use respiratory intubation in the treatment of various respiratory failure patients and anesthesia operations. There are various requirements, so artificial noses, also known as heat and moisture exchange filters, are installed on the breathing cannula. It is a device connected to the outer end of the breathing cannula to supply warm and humid air to the human body. And absorb bacteria and viruses, and exchange the temperature and moisture of the human body's exhaled gas with the inhaled gas to supply a gas that is more suitable for the human body. The existing clinically used artificial noses mostly use fine mesh gauze made of seve...
