Description

Technical Field

[0001] The utility model relates to a humidifying tank for a respirator and a respirator. Background Art

[0002] In modern clinical medicine, ventilators, as medical devices that can artificially replace spontaneous ventilation functions, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupy a very important position in the field of modern medicine.

[0003] A ventilator humidifier bottle simulates the humidity and temperature of the airway and is essential equipment for airway humidification. Existing ventilator humidifier bottles generally use manual observation and water filling operations, which often deviate significantly from the standard water volume, resulting in too much or too little water in the bottle. Since the upper respiratory tract of respiratory patients often loses the heating and humidification effects of the gas, during nursing work, when there is too much water in the bottle, the airflow will bring water to the patient's face, and in severe cases, it will even be brought into the body to block the airway, causing damage to lung function and even the risk of suffocation. When there is too little water in the bottle and the airway is not humidified enough, sputum crusts will form in the upper respiratory tract, increasing airway resistance or even blocking it, causing peripheral dyspnea and even suffocation. Therefore, stable airway humidification is very important. Utility Model Content

[0004] The utility model provides a ventilator humidification tank and a ventilator, which can effectively solve the above problems.

[0005] The utility model is achieved in this way:

[0006] A humidifier tank for a ventilator, comprising:

[0007] Tank;

[0008] An air inlet, an air outlet and a water supply pipe are arranged on the top of the tank body;

[0009] A water level line provided in the middle of the tank;

[0010] A float unit is provided inside the tank body and is used to adjust the water volume. The float unit is further used to open the water adding pipe to add water when the water level is lower than the water level line, and the float unit is used to block the water adding pipe when the water level reaches the water level line.

[0011] A ventilator comprises the above-mentioned ventilator humidification tank.

[0012] The beneficial effect of the present invention is that the ventilator humidifier tank and ventilator provided by the present invention, through the setting of the float unit, can open the water adding pipe to add water when the water level is lower than the water level line, and can block the water adding pipe when the water level reaches the water level line, thereby ensuring that the water level of the ventilator humidifier tank is maintained near the water level line, providing stable airway humidification.

It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope.

[0014] Figure 1 It is a structural schematic diagram of a humidifier tank for a ventilator provided in an embodiment of the utility model. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] Reference Figure 1 As shown, the utility model attempts to provide a ventilator humidification tank, which includes:

[0017] Tank 10;

[0018] An air inlet 11, an air outlet 12 and a water supply pipe 13 are provided on the top of the tank body 10;

[0019] A water level line 17 provided in the middle of the tank body 10;

[0020] A float unit is provided inside the tank body 10 for adjusting the water volume. The float unit is further used to open the water adding pipe 13 for adding water when the water level is lower than the water level line 17, and the float unit is used to block the water adding pipe 13 when the water level reaches the water level line 17.

[0021] As a further improvement, the float unit includes:

[0022] a connecting pipe 14 communicating with the water supply pipe 13 , wherein the connecting pipe 14 is disposed in the tank body 10 and extends below the water level line 17 ;

[0023] A float 15 is provided in the communication pipe 14 .

[0024] When the water level is lower than the water level line 17, the float 15 sinks and the water adding pipe 13 is opened to add water; when the water level reaches the water level line 17, the float 163 floats up, so that the float 15 supports the water adding pipe 13, and the water adding pipe 13 is calmly closed to add water.

[0025] The diameter of the connecting pipe 14 is generally larger than that of the water supply pipe 13. This is because the water supply pipe is generally smaller, with an inner diameter of approximately 0.5 to 1 cm. If such a diameter is used as the connecting pipe 14, it may cause clogging of the float 15. Preferably, the diameter (inner diameter) of the connecting pipe 14 is generally approximately 2 to 4 cm. In one embodiment, the diameter of the connecting pipe 14 is approximately 3 cm.

[0026] To ensure a tight closure of the water supply pipe 13, as a further improvement, a circular arc-shaped recessed structure 141 is provided at the top of the connecting pipe 14, and a circular arc-shaped protrusion 151 is further provided at the top of the float 15. The circular arc-shaped protrusion 151 cooperates with the recessed structure 141 to achieve a tight closure of the water supply pipe 13. Furthermore, the circular arc-shaped protrusion 151 can be made of a soft silicone material, thereby ensuring a tight closure of the recessed structure 141.

[0027] In other embodiments, as a further improvement, the inner wall of the connecting tube 14 can be further coated with a hydrophobic material layer, and the material of the hydrophobic material layer can be selected from fluoropolymer super hydrophobic materials. As a further improvement, the outer surface of the float 15 can also be further coated with a hydrophobic material layer. This is because, although the ventilator humidification tank uses distilled water, due to long-term use, some scale will be adsorbed on the inner wall of the connecting tube 14 or the outer surface of the float 15, and the connecting tube 14 and the float 15 are generally tightly matched to prevent the float 15 from shifting and causing the water supply pipe 13 to be unable to be tightly sealed. Therefore, the accumulation of scale will cause the connecting tube 14 and the float 15 to fit too tightly and fail to float or sink quickly. Therefore, the present invention can greatly reduce the generation of scale by coating the hydrophobic material layer. Furthermore, due to the coating of the hydrophobic material layer, the connecting tube 14 and the float 15 will also fit more smoothly without causing mutual restraint. The fluorine-containing polymer super-hydrophobic material can be PTFE, fluorinated polyethylene or fluorocarbon wax, etc., which are not limited here. The thickness of the hydrophobic material layer is generally between 100 microns and 500 microns.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
