Problems solved by technology

[0002] In order to solve the problem that medical oxygen does not contain water, so that patients generally feel that the respiratory tract is dry after inhaling oxygen, a variety of sterile oxygen delivery devices have appeared in recent years. The oxygen humidification bottle is used to humidify the oxygen, and the oxygen is passed into the liquid surface of the humidification bottle through the tube, and a large number of oxygen bubbles are generated to float out of the water and enter the terminal delivery pipe. The disadvantage of the sterile oxygen delivery device with this structure is the generation of bubbles Noise occurs; with the continuous development of medicine and related sciences, oxygen inhalation by humidified oxygen cylinders is widely used in clinical medicine. Due to the different types of diseases of patients who inhale oxygen, the etiology and the types of pathogenic microorganisms infected are also different. The humidification bottles are used in rotation among patients, which is prone to cross-infection; in addition, the inner cavity of the oxygen humidification bottle is prone to breed bacteria, which further increases the problem of cross-infection
In summary, the existing oxygen humidification bottle has the following disadvantages: 1. The traditional oxygen "water humidification" method further promotes the occurrence of nosocomial infection
2. Studies have shown that: on the premise that the existing sterile oxygen delivery device is not disposable, distilled water or saline is used as the humidification solution, and the humidification solution should not be replaced once every 8 hours at the longest. This measure can greatly reduce the humidification Pollution probability of liquid, but it also significantly increases the burden of nursing work
3. Oxygen passes through the ventilation tube to produce water bubbles that make loud noises, which often affect the patient's sleep, and the greater the oxygen flow rate, the more obvious the noise

Embodiment 1

[0021] figure 1 , 2 As shown in and 3, the aseptic oxygen delivery device of the present invention includes an annular closed container 1, a humidification unit 2 of the closed container 1, an oxygen input port 3 and an oxygen output port 4, and the closed container 1 is formed by connecting two shells up and down, A central tube 5 is arranged from top to bottom in the middle of 1 of the closed container, and a dividing plate 6 is arranged in the closed container 1 between the oxygen input port 3 and the oxygen output port 4. In the technical solution, in the closed container 1 There are 7 radial gas baffles 7 at equal angles inside the center tube 5 , and vents 8 are arranged between two adjacent gas baffles 7 inside and outside. A plurality of evenly distributed protrusions 9 are provided on the inner surface of the upper bottom surface of the closed container 1 . The humidifying unit 2 is a hydrogel. The humidification device with the above structure replaces the tradit...

Embodiment 2

[0023] The antibacterial preservative uses sodium diacetate, which has a strong inhibitory effect on mold and yeast. It is a safe product announced by the US FD. The metabolites entering the organism are water and carbon dioxide. The range of 0.05~0.15% of the total glue volume is selected, and 0.1% is selected in this embodiment, and the others are the same as in Embodiment 1.

Embodiment 3

[0025] The antibacterial preservative uses water-soluble low-molecular-weight chitosan, which has a significant antibacterial effect. There are two reasons for using this product: one is antibacterial, which is not mainly in the anti-corrosion of the gel. It plays an antibacterial effect when it accidentally causes oxygen-absorbing bacteria to pollute; secondly, chitosan also has the effect of improving the anti-infection of the body. To improve the activity of killing bacteria. Water-soluble low-molecular-weight chitosan is selected in the scope of 0.4~1.2% of hydrogel volume total amount, and this embodiment selects 0.5%, and the addition of water-soluble low-molecular-weight chitosan can also be selected 1%, and it has very strong Antibacterial effect, others are with embodiment one.

Abstract

The invention discloses a sterile oxygen supply device. The sterile oxygen supply device comprises a closed container, a humidification unit of the closed container, an oxygen input port and an oxygen output port. The closed container is composed of an upper shell and a lower shell which are connected, a central tube is arranged in the middle of the closed container from top to bottom, a baffle is arranged inside the closed container between the oxygen input port and the oxygen output port, a plurality of radiating air baffles are arranged inside the closed container at the same angle with the central tube as a center, two adjacent air baffles are internally and externally provided with vents alternately, and the humidification unit is hydrogel containing an antibiotic preservative. The sterile oxygen supply device has no noise, antibiosis, no iatrogenic infection, good oxygen humidification effect and simple structure.

Description

technical field [0001] The invention relates to a medical device, in particular to a sterile oxygen delivery device. Background technique [0002] In order to solve the problem that medical oxygen does not contain water, so that patients generally feel that the respiratory tract is dry after inhaling oxygen, a variety of sterile oxygen delivery devices have appeared in recent years, and oxygen humidification bottles are often used to humidify the oxygen, and the oxygen passes through the tube. Into the liquid surface of the humidification bottle, a large number of oxygen bubbles emerge from the water surface and enter the terminal delivery pipe. The disadvantage of the aseptic oxygen delivery device with this structure is the generation of bubbles and noise; with the continuous development of medicine and related sciences, humidification Oxygen inhalation from oxygen cylinders is widely used in clinical medicine. Due to the different types of diseases of oxygen inhalation pa...
