Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to the technical field of medical equipment, and specifically refers to a gas humidifying device and a pressure-stabilizing humidifying oxygen bag. Background Art

[0002] Oxygen bags are a type of medical equipment that is used very frequently in hospitals. They can provide oxygen to patients during the process of transferring to another department or seeing a doctor, ensuring that the patient's condition does not worsen. This is very important for the patient's life safety. However, when using oxygen bags, patients need to face two major problems:

[0003] Question 1: The oxygen in the oxygen bag is not humidified. Dry oxygen will damage and irritate the airway mucosa, causing the sputum to dry up and affecting the "scavenger" function of the cilia, affecting recovery from the disease.

[0004] Problem 2: The oxygen pressure in the oxygen bag is unstable. In the initial stage, the oxygen bag pressure is sufficient. Conventional oxygen bags use plastic pulleys that cannot accurately control the oxygen flow rate. High-pressure dry oxygen can damage the patient's nasal cavity and cause discomfort. Later, as the pressure in the oxygen bag gradually decreases, the oxygen bag cannot effectively supply oxygen to the patient.

[0005] Therefore, the utility model has developed a novel gas humidifying device and a pressure-stabilizing humidifying oxygen bag. Utility Model Content

[0006] The purpose of the utility model is to overcome the disadvantages of the prior art and provide a gas humidifying device and a pressure-stabilizing humidifying oxygen bag.

[0007] In order to achieve the above-mentioned object, the utility model provides a gas humidifying device on the one hand, which has the following structure:

[0014] Preferably, the air inlet, the air outlet, the first buffer chamber and the second buffer chamber are all provided with fixed interfaces.

[0023] In order to more clearly describe the technical content of the present invention, it is further described below in conjunction with specific embodiments.

[0024] like Figures 2 to 4 As shown, the pressure-stabilized humidifying oxygen bag provided by the utility model, the oxygen bag 10 is equipped with an oxygen pump 15, a gas humidifying device 13, and a voltage stabilizer 16, the outlet of the oxygen bag 10 is connected to the air inlet of the gas humidifying device 13 through the oxygen pump 15, and the voltage stabilizer 16 is connected to the air outlet of the gas humidifying device 13.

[0025] The regulator 16 can ensure that the oxygen flow rate is always consistent, and can also be adjusted according to the patient's condition to ensure the stability of the oxygen supply. The regulator can use a conventional regulator, for example, the Delixi AR2000 pressure regulating valve.

[0026] The oxygen pump 15 is used to extract the oxygen from the oxygen bag, thereby avoiding insufficient oxygen supply caused by insufficient pressure in the oxygen bag at a later stage and ensuring a continuous and stable oxygen supply from the oxygen bag.

[0027] Further, in the pressure-stabilized humidified oxygen bag provided by the present invention, the oxygen pump 15, the gas humidifying device 13, and the voltage stabilizer 16 are all arranged in the control box 12 (such as Figure 1 The control box 12 is arranged at one end of the oxygen bag, for example, in a fitting manner, and the control box 12 has an air inlet pipe 11 and an air outlet pipe (not shown) extending from the inside. When using the control box, it is only necessary to connect the oxygen tube to the interface.

[0028] In the embodiments provided by the utility model, it is specifically applied to oxygen bags, and can also be applied to bag-type, box-type, bottle-type and other storage containers for other gases or air. That is, it is suitable for scenarios where other gases need to be discharged from various forms of storage containers with stable pressure and humidification.

[0029] For the gas humidifying device of the utility model, if Figure 1 and 2As shown in to 4, it includes an outer shell 1, a first buffer chamber 3 and a second buffer chamber 4 located inside the outer shell 1, the first buffer chamber 3 and the second buffer chamber 4 are both provided with a plurality of air holes 5, the outer shell 1 has an air inlet and an air outlet, and the outer shell 1 is preferably able to maintain air tightness, the first buffer chamber 3 is connected to the air inlet through a hose 9, and the air outlet is connected to the second buffer chamber 4 through a hose 9, the first buffer chamber 3 is configured to remain immersed below the water surface 7 inside the outer shell 1, and the second buffer chamber 4 is configured to remain above the water surface 7 inside the outer shell 1.

[0030] In the gas humidifying device of the present invention, the moisture comes from the water inside the outer shell, so the outer shell is provided with a water inlet 14 (such as Figure 3 for supplementation.

[0031] Among them, the air inlet, air outlet, first buffer chamber and second buffer chamber are all provided with fixed interfaces 2, which are convenient for connecting hoses, that is, the first buffer chamber is connected with the air inlet through the hose 9, and the second buffer chamber is connected with the air outlet through the hose 9.

[0032] When specifically applied to an oxygen bag, after the oxygen is extracted from the outlet of the oxygen bag by the oxygen pump, the oxygen pump provides a very stable oxygen output; after the oxygen comes out of the oxygen pump, it passes through the air humidification device, and the oxygen enters the first buffer chamber inside the outer shell from the air inlet of the outer shell, and after coming out of the first buffer chamber through the air holes of the first buffer chamber, it first passes through the water humidification inside the outer shell, enters the inside of the outer shell, and then enters the second buffer chamber through the air holes of the second buffer chamber, and is thus discharged from the air outlet of the outer shell, and then is delivered to the patient for use through the stabilizer. The stabilizer can adjust the air pressure according to the conditions of different patients to ensure that the oxygen reaches the patient at the most appropriate air pressure value without causing any harm.

[0033] The humidifying device of the present invention is particularly suitable for oxygen humidification, for example, oxygen humidification of oxygen bags, and may also be suitable for other gas humidification, for example, gas humidification of other forms of gas storage containers.

[0034] The first buffer chamber 3 and the second buffer chamber 4 can both roll inside the outer shell.

[0035] The first buffer chamber 3 is kept immersed below the water surface inside the outer shell 1 by gravity, and the first buffer chamber 3 and the second buffer chamber 4 are connected by a rigid rod 6.

[0036] The outer shell 1 is a sealed hollow sphere, the first buffer chamber 3 is a semi-solid sphere, the hollow part of the semi-solid sphere is provided with the air hole and connected to the air inlet, and the second buffer chamber 4 is a hollow sphere. The spheres of the first buffer chamber and the second buffer chamber can be metal balls with holes. Thus, through the double rolling ball design, one side is a semi-solid ball, which sinks into the water under the action of gravity. Even if the oxygen bag is turned over as a whole, the two balls can still rotate with gravity inside to ensure that the semi-solid ball is in the water, further ensuring a stable oxygen humidification effect.

[0037] By adopting the gas humidifying device and the pressure-stabilizing humidifying oxygen bag of the utility model, the first buffer chamber is always immersed in water, and the second buffer chamber is on the water surface. After the gas comes out of the first buffer chamber through the air holes of the first buffer chamber, it is first humidified by the water inside the outer shell, and then enters the second buffer chamber, and is thus discharged from the air outlet of the outer shell, thereby ensuring a stable oxygen humidification effect.

[0038] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
