Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an oxygen regulating control device for a ventilator. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means to artificially replace, control, or change the spontaneous ventilation function, 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] In existing ventilators, the detection and control of the high-pressure input processing at the front end of the gas source and the low-pressure output at the back end are separated into modules connected by joints and hoses to form a detection system.

[0045] Figure 1-3 The oxygen regulating control device for a ventilator in some embodiments of the present invention is shown, which is used for a ventilator. The oxygen regulating control device for a ventilator in the embodiment of the present invention includes a base 1 and the following components arranged on the base 1: a high-pressure oxygen access component 20, a pressure regulating valve 10, a proportional valve 15, a flow sensor output component 30, a low-pressure oxygen connector 6, an oxygen pressure measuring component 7, a nebulizer output component 40 and an air container 14. The high-pressure oxygen is connected through the high-pressure oxygen access component 20, and then adjusted by the pressure regulating valve 10 to become low-pressure oxygen. The flow direction of the low-pressure oxygen is divided into three routes: the first route is adjusted by the proportional valve 15, and the external low-pressure oxygen connected to the low-pressure oxygen connector 6 is merged and output through the flow sensor output component 30; the second route is measured by the oxygen pressure measuring component 7; the third route is output to the external nebulizer through the nebulizer output component 40. The above-mentioned components are integrated with the base 1 as a whole, which is convenient for assembly, maintenance and debugging.

[0046] The base 1 may be a solid metal base made of metal material, and an oxygen channel 16 is provided inside the base 1. The base 1 may be at least one of a cube, a cylinder, an ellipsoid, and a trapezoid, and no specific limitation is made here, as long as the relevant functions can be realized. Preferably, the base 1 is a rectangular parallelepiped. In some embodiments, the base 1 is combined with Figure 3 , 4 As shown in , 5, 6A-6F, the rectangular parallelepiped base 1 includes a top surface, a bottom surface 160 and four side surfaces, and the four side surfaces include a first side surface 110, a second side surface 120, a third side surface and a fourth side surface that are adjacent to each other in sequence. Figure 4 , 5 As shown, the front view is the first side 110, the left view is the bottom 160, the right view is the top, the top view is the second side 120, the bottom view is the fourth side, and the rear view is the third side. The high-pressure oxygen access assembly 20 is arranged on the first side 110, the proportional valve 15 is arranged on the second side 120, the pressure regulating valve 10 and the flow sensor output assembly 30 are arranged on the third side, and the low-pressure oxygen connector 6, the oxygen pressure measurement assembly 7, and the nebulizer output assembly 40 are arranged on the fourth side. In other embodiments, the high-pressure oxygen access assembly 20 and the flow sensor output assembly 30 are located on different sides of the base 1.

[0047] The high pressure oxygen access assembly 20 is used to access high pressure oxygen. Figure 1-7 As shown, the high-pressure oxygen access component 20 includes a high-pressure oxygen connector 2, a sealing ring 3, a first filter 4, and a gasket 5, which are arranged in sequence. The high-pressure oxygen connector 2 is arranged at the entrance of the oxygen channel 16, and is used to connect the oxygen pipeline to access external high-pressure oxygen. The sealing ring 3 is installed on the high-pressure oxygen connector 2 and arranged between the high-pressure oxygen connector 2 and the first filter 4, and plays a sealing role. It is preferably an O-ring. The first filter 4 is used to filter the external high-pressure oxygen. Preferably, the pore size of the filter hole of the first filter 4 does not exceed 100um, so as to prevent the entry of particulate impurities with a particle size greater than 100um in the input high-pressure oxygen. The gasket 5 is arranged between the first filter 4 and the base 1, and plays a role in protecting the first filter 4. The gasket 5 is preferably an elastic gasket.

[0048] For example Figure 1 , 2 As shown in FIG. 3 , the pressure regulating valve 10 is connected to the high-pressure oxygen access assembly 20 to adjust the pressure of the incoming high-pressure oxygen to make it low-pressure oxygen. The proportional valve 15 is connected to the pressure regulating valve 10 to adjust the output flow of the low-pressure oxygen.

[0049] The flow sensor output assembly 30 is connected to the proportional valve 15 to detect the output flow and output it to the outside. Figure 8 As shown, the flow sensing output assembly 30 includes a flow sensor 12 for detecting the output flow and a second filter 13 for filtering, and the second filter 13 is arranged between the flow sensor 12 and the base 1.

[0051] The oxygen pressure measuring assembly 7 is connected to the pressure regulating valve 10 to measure the pressure of the low-pressure oxygen. Alternatively, the other end of the oxygen pressure measuring assembly 7 is connected to an external monitoring panel (not shown) using a hose so that the oxygen pressure value can be monitored in real time.

[0052] Combination Fig. 9 As shown, the atomizer output assembly 40 is connected to the pressure regulating valve 10 and outputs low-pressure oxygen to the external atomizer. The atomizer output assembly 40 includes a switch valve 11 for adjusting the third-way switch and an atomizer connector 8 connected to the external atomizer. The switch valve 11 is arranged on the base 1. It can be understood that the opening and closing of the atomization channel can be controlled by adjusting the switch valve 11.

[0053] For example Figure 3 As shown, the gas container 14 is used to reduce the noise in the cavity, and the gas container 14 is arranged on the base 1. Among them, the gas container 14 can store a certain amount of gas, stabilize the gas flow, reduce the impact noise of the airflow, and reduce the gas pressure fluctuation; the airflow expands, diffuses, reflects, and interferes with each other inside to reduce the noise. In some embodiments, there is also a plug 9, which is installed on the base 1 to play a sealing role.

[0054] The present invention is used in an oxygen regulating control device for a ventilator. By arranging various components on a base 1, a highly integrated overall module is formed. The various components are connected through internal channels of the base 1. Air paths are correspondingly arranged in the base 1 and are connected to corresponding joints, valves, etc., to form an independent oxygen transmission and control system, which saves the use of hose connections and the connection of multiple modules, thereby reducing material costs, being stable and reliable as a whole, and simplifying debugging, and being easy and efficient to maintain.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
