Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-6, the present invention provides a technical solution of a novel simple respirator structure:
the utility model provides a novel simple and easy respirator structure, includes check valve 1, respirator sacculus 2 and admission valve 3, and check valve 1, respirator sacculus 2 and admission valve 3 connect gradually. The one-way valve 1 comprises a one-way valve upper cover 4, a duckbill valve 5, a patient end interface 6 and a one-way valve lower cover 7 which are connected in sequence. Check valve 1 can guarantee that gas flows to check valve 1 from respirator sacculus 2 all the time, effectively prevents that gas backward flow from causing the first aid that can't provide sufficient oxygen and lead to for the patient inefficacy. A pressure limiting valve 8 is arranged at the upper cover 4 of the one-way valve, and when the air pressure in the one-way valve 1 is overlarge, the air in the one-way valve 1 is discharged out of the one-way valve 1 through the pressure limiting valve 8. The respirator sacculus 2 comprises a patient side connecting port 9 and an air inlet valve side connecting port 10, a fixed joint 11 is arranged at the patient side connecting port 9, and an internal thread 12 is arranged in the fixed joint 11. Corresponding with fixed joint 11's internal thread 12, be equipped with respirator sacculus connector 13 on check valve 1, respirator sacculus connector 13 department is equipped with external screw thread 14 for check valve 1 realizes threaded connection with fixed joint 11, can guarantee under both connected leakproofness's the prerequisite, realizes being convenient for dismantle respirator sacculus 2 and admission valve 3 from check valve 1. The air inlet valve 3 comprises an air inlet valve seat 15 and an air inlet valve cover 16, and the air inlet valve seat 15 is fixedly connected with the air inlet valve side connecting port 10 of the respirator sacculus 2. In order to keep the air inlet stability of the respirator saccule 2, an inner air inlet valve plate 17 is arranged on the air inlet valve seat 15. When gas flows from the gas inlet valve 3 to the respirator balloon 2, the inner gas inlet valve sheet 17 is opened; when the gas stops flowing from the air inlet valve 3 to the respirator ball 2 bag, the inner air inlet valve plate 17 is closed to prevent the gas from flowing backwards. The air inlet valve cover 16 is provided with an external air inlet valve sheet 18, an external air outlet valve sheet 19, an air storage bag connecting port 20 and an oxygen pipe connecting port 21. The outer air inlet valve plate 18 and the outer air outlet valve plate 19 are both one-way valves. The outer inlet valve plate 19 ensures that the air flow can only flow from the outside atmosphere to the inside of the inlet valve 3. The air outlet valve plate 19 can prevent the internal pressure of the device from being too large and release a part of pressure to the atmosphere. The gas storage bag connection port 20 is used for connecting an external gas storage bag, so that the device can be used under the condition without an external power gas source. The oxygen tube connection port 21 can be used for connecting a power gas source. In order to prevent slipping of the hands of the caregiver during use when the device is wet, a plurality of anti-slip indentations 22 are provided in the surface of the respirator balloon 2.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
