Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a multifunctional medical oxygen terminal pressure measuring device. Background Technology
[0002] Oxygen terminals on existing hospital ward equipment belts conform to multiple standards, such as the Chinese national standard, the old aerospace standard, the German standard, the American standard, the British standard, and the Japanese standard. Many hospitals have had their wards built and equipment belts installed at different times and stages, resulting in the simultaneous presence of oxygen terminals of various standards. This creates difficulties for pressure testing, requiring multiple oxygen pressure gauges with different standard plugs. Different plugs must be used depending on the standard of the oxygen terminal; for example, a pressure gauge with a German standard plug must be used to test a German standard oxygen terminal, and a pressure gauge with an American standard plug must be used to test an American standard oxygen terminal. This not only requires multiple pressure gauges but is also inconvenient and increases testing costs. Furthermore, since the oxygen terminals are installed inside the wall, replacing all oxygen terminals at once would be costly, time-consuming, and impractical. Therefore, there is an urgent need to further improve the structure and design of existing pressure testing devices to meet the pressure testing requirements of oxygen terminals of different standards, but so far, no relevant public reports have been found. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a multifunctional medical oxygen terminal pressure measuring device, which can effectively solve the problem that the existing single oxygen terminal pressure measuring device cannot meet the pressure detection of oxygen terminals of different standards.
[0004] To achieve the above objectives, the technical solution provided by this utility model is a multifunctional medical oxygen terminal pressure measuring device, comprising a pressure gauge, wherein the pressure gauge is connected to one end of a hose via a quick connector, the other end of the hose is connected to one of the connectors of a multi-port quick connector, the other connectors of the multi-port quick connector are respectively connected to the outlet end of a one-way valve via hoses, and the inlet end of the one-way valve is respectively connected to various standard oxygen plugs via hoses.
[0005] This utility model has a simple structure and a scientific and reasonable design. It integrates oxygen plugs of different standards into one unit, and can measure the pressure of various standard oxygen terminals without any conversion or disassembly. This reduces the testing cost, is convenient to use, and has good social and economic benefits. Attached Figure Description
[0006] Figure 1 This is a three-dimensional structural diagram of the present invention. Detailed Implementation
[0007] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings and specific circumstances.
[0008] As shown in the accompanying drawings, a multifunctional medical oxygen terminal pressure measuring device includes a pressure gauge. The pressure gauge 1 is connected to one end of a hose 2 via a quick connector. The other end of the hose 2 is connected to one of the connectors of a multi-port quick connector 3. The other connectors of the multi-port quick connector 3 are connected to the outlet end of a one-way valve 6 via the hose 2. The inlet end of the one-way valve 6 is connected to various standard oxygen plugs via the hose 2.
[0009] To ensure better implementation results, the pressure gauge 1 is an oxygen pressure gauge.
[0010] The aforementioned multi-port quick connector 3 is a quick connector with six or more ports, to facilitate the expansion of more standard oxygen plugs.
[0011] The aforementioned multi-port quick connector 3 is a six-port quick connector.
[0012] The different types of oxygen plugs mentioned are American standard oxygen plug 4, British standard oxygen plug 5, German standard oxygen plug 7, Chinese standard oxygen plug 8, and old aerospace oxygen plug 9.
[0013] The hose 2 mentioned above is a special oxygen tube.
[0014] In the manufacturing process of this invention, the oxygen pressure gauge 1 is converted from a threaded connection to a quick-connect coupling via an adapter. A section of flexible tubing 2 is inserted into the quick-connect coupling. The length of the plastic tubing 2 can be shortened or lengthened as needed to meet usage habits and different operating conditions. The tubing 2 is then inserted into one of the connectors of a six-way quick-connect coupling 3. The other five connectors of the six-way quick-connect coupling 3 are each connected to five tubing 2. A one-way valve 6 is installed at the lower end of each of the five tubing 2. A section of tubing 2 is then inserted into the lower end of each one-way valve 6. Finally, five oxygen plugs of different standards (e.g., American standard oxygen plug 4, British standard oxygen plug 5, German standard oxygen plug 7, Chinese standard oxygen plug 8, old aerospace oxygen plug 9, etc.) are inserted into the lower end of each tubing 2. All component interfaces can use threaded connections or quick-connect connections. For ease of maintenance and component replacement, this invention uses quick-connect couplings. For ease of installation, the connection parts of various standard oxygen plugs and plastic tubing use pagoda-type connectors.
[0015] In practical use, when it is necessary to measure the oxygen pressure of a certain standard oxygen terminal, the corresponding standard oxygen plug is inserted into the oxygen terminal. For example, to measure the oxygen pressure of a German standard oxygen terminal, the German standard oxygen plug 7 of this invention is inserted into the German standard oxygen terminal. Due to the oxygen pressure, the one-way valve 6 corresponding to the German standard oxygen plug 7 opens, oxygen enters, and the oxygen pressure gauge 1 displays the actual oxygen pressure. At the same time, the other standard oxygen plugs on the pressure measuring device are closed due to the action of the one-way valves, preventing gas leakage. When it is necessary to measure the pressure of other standard oxygen terminals, the corresponding operation and effect are the same.
[0016] This utility model features a simple structure and a scientifically sound design, integrating oxygen plugs of different standards into one unit. It requires no conversion or disassembly, enabling the measurement of pressure from various standard oxygen terminals, thus reducing testing costs. It is portable, easy to use, and can be easily expanded in the future. This brings convenience to oxygen terminal pressure testing in hospitals with multiple standard oxygen terminals, saving costs and reducing the complexity of use. It offers significant social and economic benefits.
