Abstract
A carbon dioxide filter comprises a casing and a switch mounted on the casing; a gas inlet interface, a gas outlet interface and a test interface are machined on the casing; a filter screen is arranged in the gas outlet interface and a piece of litmus paper is arranged in the test interface. When the structure of the utility model is adopted, the gas can be tested before the carbon dioxide filter is used, and the misconnection of the gas for operation is avoided; the carbon dioxide filter has simple structure, convenient use and eliminates the potential hazards in operation. As a safety valve is mounted on the casing of the carbon dioxide filter, the pressure of the gas in use can be relieved when the pressure exceeds the working pressure, the filter and the connecting pipeline cannot be damaged, and the carbon dioxide filter is ensured to be safe and stable.
Description
Technical field:
The utility model relates to Medical Devices consumptive material technical field, more specifically to a kind of identification, filtration and safe handling device that is used for carbon dioxide.
Background technology:
The developing direction of following operation is that patient safety, wound are little.Now more and more Minimally Invasive Surgeries carries out, rely on the help of chamber mirror display system mostly, often need use pneumoperitoneum apparatus to set up carbon dioxide pneumoperitoneum or air cavity in chamber mirror display system operation, carbon dioxide pneumoperitoneum or air cavity build up the back operation and get a clear view and be convenient to operation technique.Conventional use electric knife cuts and stops blooding in surgical procedure, if at gas the wrong gas of fashionable dress is installed, (example: as carbon dioxide, the spark of electric knife generation can cause the blast of patient's lacuna oxygen.) consequence is hardly imaginable.The interface of all gases steel cylinder is all general, and is not exclusively used in the pneumoperitoneum apparatus or the pneumatic filter of identification carbon dioxide at present, has many risk hidden danger in the operation.
The utility model content:
The purpose of this utility model provides a kind of carbon dioxide pass filter that can carry out the carbon dioxide detection, and it is simple in structure, and is easy to use, safe and reliable.
Technology solution of the present utility model is as follows:
A kind of carbon dioxide pass filter comprises housing and is installed in switch on the housing, has intake interface on the housing, an interface of giving vent to anger, test interface, is provided with screen pack in the interface of giving vent to anger, and is provided with litmus paper in the test interface.
Described carbon dioxide pass filter, described switch is made up of the nut and the rotating shaft that are screwed onto on the housing, and rotating shaft top is plugged with knob, and the bottom is equipped with sealing ring.
Described carbon dioxide pass filter, described litmus paper are latticed.
Described carbon dioxide pass filter, described housing safety valve is installed.
The utility model beneficial effect is:
1, a kind of carbon dioxide pass filter comprises housing and is installed in switch on the housing, has intake interface on the housing, an interface of giving vent to anger, test interface, is provided with screen pack in the interface of giving vent to anger, and is provided with litmus paper in the test interface.Adopt structure of the present utility model, can carry out gas before use and detect, avoid the wrong operation to use gas, it is simple in structure, and is easy to use, has got rid of the hidden danger that exists in the operation.
2. owing to the safety valve that is equipped with of housing of the present utility model, can not damage at using gases above conscientious pressure release in the working pressure to pass filter and connecting line, safe and reliable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 front view of the present utility model;
Fig. 2 A-A cutaway view of the present utility model.
The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See that accompanying drawing 1 is to shown in the accompanying drawing 2: a kind of carbon dioxide pass filter, comprise housing 1 and the switch 14 that is installed on the housing 1, have intake interface 2 on the housing 1, the interface 3 of giving vent to anger, test interface 4, be provided with screen pack 5 in the interface 3 of giving vent to anger, be provided with litmus paper 6 in the test interface 4.
Described switch 5 is made up of the nut 8 and the rotating shaft 10 that are screwed onto on the housing 1, and rotating shaft 10 tops are plugged with knob 9, and the bottom is equipped with sealing ring 11.
Described litmus paper 6 is latticed.
Described housing 1 safety valve 7 is installed.
Operation principle: in the time of use, intake interface 2 connects the gas cylinder inlet ductwork, the interface of giving vent to anger connects 3 outlet pipes, litmus paper 6 usefulness distilled water in the test interface 4 are soaked, select knob 9 then, driven rotary axle 10 forwards to, hole 15 on the chosen axis 10 is communicated with intake interface 2, because hole 15 communicates with hole 13,, observe blue litmus paper 6 and whether become redness so passed through the wet litmus paper 6 that is provided with in the test interface 4 by the gas of intake interface 2, if variable color then represent that the gas that connects is carbon dioxide, otherwise then correct, safety valve 7 communicates with air inlet 2 by hole 12, the safety when guaranteeing test and use.
