Description

Technical Field

[0001] The present invention relates to the technical field of medical oxygen supply, in particular to an oxygen inhalation device for cardiology nursing. Background Art

[0002] Oxygen therapy refers to the administration of oxygen to increase blood oxygen partial pressure and saturation, increase blood oxygen content, correct hypoxia caused by various reasons, promote tissue metabolism, and maintain the body's vital activities. Oxygen inhalation is a commonly used treatment in the treatment of cardiovascular diseases such as heart failure and myocardial infarction. The oxygen provided by oxygen cylinders or pipe oxygen supply devices is dry and can cause dryness of the respiratory mucosa after inhalation. Therefore, the oxygen needs to be humidified to reduce irritation to the respiratory mucosa and make the patient feel comfortable. Bubble humidification is the most commonly used humidification method for patients receiving oxygen in clinical practice. Oxygen forms small bubbles after passing through the sieve holes, which increases the contact area between oxygen and water. The more sieve holes, the larger the contact area and the better the humidification effect. Although it has the advantages of simplicity and low cost, the humidification effect is poor.

[0019] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] like Figure 1 As shown, the oxygen inhalation device for cardiology nursing proposed in the present invention includes a basic humidification module 1, a temperature control and moisturizing module 2, an ultrasonic atomization module 3, an oxygen inhalation mask 4, a control module 5, and a respiratory monitoring module 6. The basic humidification module 1 is connected to the temperature control and moisturizing module 2, the control module 5 is arranged on the upper surface of the basic humidification module 1, the ultrasonic atomization module 3 is detachably connected to the temperature control and moisturizing module 2, the temperature control and moisturizing module 2 is connected to the oxygen inhalation mask 4 via an trachea, and the control module 5 is respectively communicated with the temperature control and moisturizing module 2, the oxygen inhalation mask 4, and the respiratory monitoring module 6.

[0021] The basic humidification module 1 is used to humidify oxygen using bubbles and specifically includes a drive box 101 and a bubble formation box 103. The drive box 101 is connected to an oxygen source via an oxygen inlet pipe. The oxygen source can be an oxygen tank, an oxygen generator, etc. The drive box 101 is connected to the bubble formation box 103 via an oxygen delivery pipe 102. The drive box 101 is internally provided with an oxygen drive shaft 104. The middle portion of the oxygen drive shaft 104 is sleeved with rotating blades 105, which can rotate under the propulsion of oxygen. The bottom end of the oxygen drive shaft 104 extends out of the drive box 101 and is provided with a first transmission gear 106. A bubble shear shaft 108 is installed within the basic humidification module 1. The top end of the bubble shear shaft 108 is connected to the basic humidification module 1, while the bottom end of the bubble shear shaft 108 is located within the bubble formation box 103 and connected to the bottom surface of the bubble formation box 103. The bubble shear shaft 108 is equipped with a drive gear 109. The first transmission gear 106 is connected to the drive gear 109 via the second transmission gear 107. An impeller 110 is mounted on the portion of the bubble shear shaft 108 located within the bubble formation box 103. Filter tanks 1031 are located on both sides of the bubble formation box 103. A filter membrane is installed within the filter tank 1031. The filter membrane is permeable only to gas but not liquid. During operation, the basic humidification module 1 is filled with distilled water, and the liquid level of the distilled water is lower than the bottom end of the oxygen drive shaft 104. During operation, the incoming oxygen pushes the rotating blades 105 to rotate, and then enters the bubble forming box 103 through the oxygen delivery pipe 102. The rotating blades 105 drive the oxygen drive shaft 104 to rotate. The oxygen drive shaft 104 drives the bubble shearing shaft 108 to rotate through the first transmission gear 106, the second transmission gear 107 and the driving gear 109. The bubble shearing shaft 108 drives the impeller 110 to rotate, shearing the oxygen to form bubbles. The oxygen is then discharged into the distilled water through the filter tank 1031. The tiny oxygen bubbles will float upward under the action of their own buoyancy to achieve the humidification of the oxygen. The humidified oxygen is output to the temperature control and moisturizing module 2.

[0022] The temperature control and moisturizing module 2 is a cylindrical structure with a graphene electric heating film 21 on its inner surface. This film features a special waterproof and insulating design, allowing it to operate in humid environments. Multiple first temperature sensors 22 are evenly distributed around the oxygen input port, and the bottom is connected to an ultrasonic atomization module 3, which provides atomized distilled water to the temperature control and moisturizing module 2. During operation, the control module 5 sets the target temperature for the temperature control and moisturizing module 2. The graphene electric heating film 21 heats the oxygen inside, bringing it to the target temperature under the monitoring of the first temperature sensor. The atomized distilled water is used to ensure the humidity of the oxygen.

[0023] like Figure 2As shown, the oxygen mask 4 includes a shell 41, and a second temperature sensor 42, an oxygen valve 43 and a ventilation module are sequentially arranged inside the shell 41. The second temperature sensor 42 is a non-contact temperature sensor, which is tilted and facing the nostrils, and is used to detect the outlet temperature of the nostrils. The oxygen valve 43 is arranged below the second temperature sensor 42 and is connected to the temperature control and moisturizing module 2 through the trachea to control the input of oxygen. The ventilation module is arranged at the bottom of the shell 41 and is used to update the air inside the oxygen mask 4 and discharge the carbon dioxide and water vapor inside in time. The ventilation module includes a micro fan 44 and a one-way valve 45. The micro fan 44 rotates to draw the internal air out, and the one-way valve 45 ensures the one-way outflow of air.

[0024] like Figure 3 As shown, the respiratory monitoring module 6 includes a fixing belt 61, which is made of elastic material and has two ends connected by Velcro. An acceleration sensor 62 is set in the middle position of the fixing belt 61. Since the abdomen will be concave when exhaling and will bulge when inhaling, the state of breathing can be judged according to the state of the abdomen. Therefore, when working, the respiratory monitoring module 6 is worn on the patient's abdomen, and the state of the abdomen can be judged according to the data of the acceleration sensor, thereby judging the state of breathing.

[0025] The control module 5 determines the patient's respiratory state based on the data from the respiratory monitoring module 6, determines the patient's respiratory rate based on changes in the patient's respiratory state, extracts data from the second temperature sensor based on the respiratory rate and current respiratory state, determines the temperature within the nasal cavity, and sets the target temperature of the temperature control and moisturizing module to the temperature within the nasal cavity. This ensures that the oxygen temperature output by the temperature control and moisturizing module is close to the actual temperature within the nasal cavity, thereby improving the patient's comfort. Furthermore, the moisture carried by the oxygen will not condense in the nasal cavity due to excessively high oxygen temperature, resulting in large-scale loss and inability to enter the deep respiratory tract. This allows more moisture to enter the deep respiratory tract, and controls the operation mode of the micro-fan based on the respiratory rate and current respiratory state. The specific process of extracting data from the second temperature sensor based on the respiratory rate and current respiratory state and determining the temperature within the nasal cavity is to calculate the time when each exhalation action occurs based on the respiratory rate and current respiratory state, collect data from the second temperature sensor during each exhalation action between three exhalations, and use the average value of the data as the temperature within the nasal cavity. The specific process of controlling the working mode of the micro fan based on the respiratory frequency and the current respiratory state is to calculate the time when each exhalation action occurs according to the respiratory frequency and the current respiratory state, and start the micro fan to exhaust during the exhalation action between every three exhalation actions.

[0026] The above disclosure is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. It should be noted that for those skilled in the art, any equivalent changes made to the present invention without departing from the design structure and principles of the present invention are considered to be within the scope of protection of the present invention.
