Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an oxygen humidification tank for a non-invasive ventilator. Background Art

[0002] CPAP is a non-invasive ventilator used clinically to treat sleep apnea syndrome (SAS) and related diseases. These diseases cause decreased blood oxygen saturation, increased sympathetic nerve tension, decreased parasympathetic nerve tension, increased blood carbon dioxide concentration, decreased pH value, and increased negative pressure in the chest, which seriously affect the functions of various important organs. In particular, brain function and cardiovascular function are the first to be affected.

[0003] However, when the oxygen humidifier of the current non-invasive ventilator is in use, nurses or family members need to pay attention to the situation in the oxygen humidifier at all times to prevent the distilled water inside from running out. Once the distilled water runs out and cannot be added in time, it will cause dry burning, which will greatly increase the burden on the equipment and easily cause damage. If nurses or family members pay attention to and add water all the time, it will also increase the burden of manpower. If too much is added, it is easy to cause the patient to aspirate, increase the burden on the lungs, and have difficulty breathing, which is very inconvenient to use. Therefore, we propose a new oxygen humidifier for non-invasive ventilators. Utility Model Content

[0012] As a further description of the above technical solution, the model of the controller is AT89S51 single chip microcomputer.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By arranging the humidification tank body, the first water level line, the first water level sensor and the control module in coordination, it is possible to avoid mistakes when manually adding distilled water into the humidification tank body, resulting in excessive addition of distilled water, thereby avoiding aspiration by the patient, increasing the burden on the lungs, and causing difficulty in breathing, and the safety is higher.

[0024] See also Figure 1-3The utility model provides a technical solution: a non-invasive ventilator oxygen humidification tank, comprising a humidification tank body 1, wherein the humidification tank body 1 is a hollow tank-shaped structure made of silica gel, and a first water level line 2, a second water level line 3 and a third water level line 4 are arranged on the humidification tank body 1, and the first water level line 2, the second water level line 3 and the third water level line 4 are fixedly arranged on the humidification tank body 1 from top to bottom, and a water inlet pipe 5 is fixedly connected to the top of the humidification tank body 1, and the water inlet pipe 5 is used to transport distilled water into the humidification tank body 1, and an air inlet pipe 6 is fixedly connected to one side of the top of the humidification tank body 1, and the air inlet pipe 6 is used to infuse oxygen into the humidification tank body 1. It is explained here that the bottom end of the air inlet pipe 6 extends into the lower end of the humidification tank body 1, and the height of the bottom end is lower than the height of the third water level line 4. The other side of the top of the humidification tank body 1 is fixedly connected with an air outlet pipe 7, and the air outlet pipe 7 is used to transport humidified oxygen into the patient's body. The first water level sensor 8 and the second water level sensor 9 are fixedly installed on the inner side wall of the humidification tank body 1. The first water level sensor 8 is installed corresponding to the first water level line 2, and is used to detect the water level condition at the first water level line 2. The second water level sensor 9 is installed corresponding to the second water level line 3 and the third water level line 4, and is used to detect the water level condition at the second water level line 3 and the third water level line 4.

[0025] The humidification tank also includes a control module 10, which includes a controller, a micro water pump 101, a solenoid valve 102 and a buzzer 103. The controller adopts an AT810S51 single-chip microcomputer, which has a small size, low cost, many T / 0 pins, high reliability, strong anti-interference ability, and simple programming. The water outlet of the micro water pump 101 is fixedly connected to the water inlet pipe 5, and its water suction port extends into the distilled water source. The solenoid valve 102 is fixedly installed on the water inlet pipe 5 for controlling the opening and closing of the water inlet pipe 5. The buzzer 103 is fixedly installed on the humidification tank body 1.

[0026] The controller is electrically connected to the micro water pump 101, the solenoid valve 102 and the buzzer 103 through wires, and the signal output ends of the first water level sensor 8 and the second water level sensor 9 are electrically connected to the controller. It is hereby explained that the humidification tank provides power support to the controller, the micro water pump 101, the solenoid valve 102, the buzzer 103, the first water level sensor 8 and the second water level sensor 9 through an external power supply, and the above-mentioned equipment are all currently known existing technologies, so their working principles are not described here again.

[0027] It should be noted that the utility model is an oxygen humidification tank for a non-invasive ventilator. When in use, the humidification tank is first connected to an external power supply, and then the water suction port of the micro water pump 101 is extended into the distilled water source. During use, when the distilled water level in the humidification tank body 1 drops to the second water level line 3, the second water level sensor 9 will detect the distilled water level information at this time and transmit it to the controller. The controller receives the water level information transmitted by the second water level sensor 9, and then controls the micro water pump 101 to start according to its built-in program. At the same time, the solenoid valve 102 will also be controlled to open, and the water in the distilled water source will be pumped out by the micro water pump 101, and finally transported to the humidification tank body 1 from the water inlet pipe 5. When the distilled water level in the humidification tank body 1 rises to the first water level line 2, the first water level sensor 8 will detect the distilled water level information at this time and transmit it to the controller. The controller receives the water level information transmitted by the first water level sensor 8, and then controls the micro water pump 101 to start according to its built-in program. The program is used to control the micro water pump 101 and the electromagnetic valve 102 to close, so as to prevent the distilled water level in the humidification tank body 1 from exceeding the first water level line 2, and to prevent the patient from accidentally inhaling the distilled water due to the high water level close to the trachea 7, thereby increasing the burden on the lungs and causing difficulty in breathing. It is explained here that when the distilled water level in the humidification tank body 1 drops to the second water level line 3, if the oxygen humidification tank encounters a failure of the micro water pump 101, or the controller cannot control the micro water pump 101 and the electromagnetic valve 102 to open, problems will occur in the automatic water addition, resulting in failure to timely infuse distilled water into the humidification tank body 1, thereby causing the distilled water level in the humidification tank body 1 to continue to drop. When it drops to the third water level line 4, the second water level sensor 9 will detect the distilled water level information at this time and transmit it to the controller. The controller receives the water level information transmitted by the second water level sensor 9, and then controls the buzzer 103 to sound an alarm according to its built-in program to alert the nurses for emergency treatment. Compared with the existing non-invasive ventilator oxygen humidifier tank, the utility model is simple and practical. When the water level in the humidifier tank is too low, water can be added automatically, reducing the workload of nurses. It can also avoid excessive water addition at one time, which may cause the patient to aspirate accidentally, increase the burden on the lungs, and cause breathing difficulties. It is safer and more reliable.
