Problems solved by technology

The disposable oxygen humidification filter proposed in this patent solves the problem of the bursting of the humidification cup after repeated use, but it does not completely solve the pollution of the humidification liquid and the oxygen humidification bottle
Although the patent proposes the application of a waterproof and breathable membrane, due to the limitation of the material of the waterproof filter membrane and how to install it, it will inevitably lead to some oxygen bypassing the waterproof membrane and directly entering the humidification solution, which will not only cause pollution of the humidification solution , and more importantly, the purity of the oxygen delivered to the patient cannot be reliably guaranteed

Embodiment 1

[0020] The first embodiment of the present invention is figure 1 As shown, it includes a filter bottle 1, an upper cover 2 threaded with the filter bottle, an oxygen inlet 3 located in the center of the upper cover, an oxygen input tube 5 connected to the oxygen inlet, and the shape of the filter bottle It is streamlined with a thick top and a thin bottom. The oxygen input pipe extends into the bottom of the bottle body. The bottom end of the oxygen input pipe passes through the mold casing 9 and penetrates into the lower arc-shaped cavity 10 between the nut 6 and the mold casing 9, and passes through The nut 7 is positioned; the mold jacket 9 is a circular ring with threads on the inner wall and air holes on the top surface; the oxygen filter membrane 8 made of polytetrafluoroethylene is arranged under the inner top surface of the mold jacket 9, and the oxygen filter membrane 8 The nut 6 is pressed tightly with the mold jacket 9, and the nut and the mold jacket are screwed to...

Embodiment 2

[0023] The second embodiment of the present invention is figure 2 As shown, the difference from Example 1 is that oxygen enters directly from the bottom of the bottle body, the bottle body is a cylindrical shape with upper and lower ends transparent, and the lower end of the filter bottle body is provided with a flanged lower mouth, and the lower mouth is The bottom of the flange is provided with threads, the bottle body of the threaded part and the flange of the lower mouth form a mold jacket 9, and the lower cover 11 is connected to the threaded part. The port 3 is located on the lower cover 11. In this embodiment, no oxygen input pipe is provided, and a pin 13 is provided at the bottom of the lower cover.

Abstract

The invention discloses a disposable oxygen humidifying filter which comprises an oxygen inlet, a filter bottle body containing humidifying liquid comprising an epsilon-poly-L-lysine bacteriostatic agent or a V80 bacteriostatic agent or compound borax solution, an upper cover matched with the filter bottle body, an oxygen outlet arranged at the upper cover and connected with a nasal oxygen cannulaor an oxygen mask and an oxygen filter membrane positioned at the bottom of the filter bottle body, fixed horizontally through an outer sleeve of a mold and made of polytetrafluoroethylene or modified polytetrafluoroethylene, expanded polytetrafluoroethylene and compound materials thereof, wherein the oxygen outlet end of the oxygen inlet extends into the outer sleeve of the mold and is positioned below the oxygen filter membrane. The disposable oxygen humidifying filter can increase the contact area of oxygen with the humidifying liquid, effectively improve the humidifying effect, lead the oxygen to smoothly pass through, fully filter out pathogenic microorganisms in the oxygen, avoid the occurrence of cross-infection and ensure the safety of oxygen inhalation of a patient.

Description

technical field [0001] The invention relates to an oxygen humidification device used by patients inhaling oxygen in the medical field, in particular to a disposable oxygen humidification filter. Background technique [0002] In the medical field, oxygen delivery is an important medical measure to rescue critically ill patients, and the oxygen humidification device in the oxygen delivery equipment is one of the essential medical equipment in the hospital. The research and test of medical research workers on the currently used oxygen humidification bottle shows that the oxygen humidification bottle is easily contaminated by patients, and its inner core is the most dangerous factor leading to infection; among them, the pollution of the humidification liquid is the most serious cause of lung cancer in patients. One of the main pathogens of internal superinfection, the infection of humidification fluid is often caused by the impurity of oxygen. The currently used oxygen humidifi...
