Abstract
The utility model discloses a kind of thoracic duction instrument, include fluid collection chamber, water seal cavity and pressure regulating cavity that side integrally connects successively; Be connected with flow sub above described fluid collection chamber and be communicated with joint; Be connected with water sealing (sealing water) pipe above described water seal cavity, water sealing (sealing water) pipe lower end reaches bottom water seal cavity, is communicated with between joint and water sealing (sealing water) pipe and is connected with communicating pipe; Be connected with liquid-feeding tube above described pressure regulating cavity and attract joint, liquid-feeding tube lower end reaches bottom pressure regulating cavity, is also connected with gas-storing bag connection tube above described water seal cavity, gas-storing bag connection tube is connected with a gas-storing bag; A vent valve is connected with by pipeline between above described water seal cavity and pressure regulating cavity.Can be stored in gas-storing bag when having gas to discharge in thoracic cavity, the capacity of gas-storing bag is determined value, waits after gas-storing bag fills gas, opens vent valve by the evacuate air in gas-storing bag, then close vent valve again, this makes it possible to the number knowing chest Exhaust Gas comparatively accurately.
Description
Technical field
This utility model belongs to field of medical health care equipment, is specifically related to a kind of structure of thoracic duction instrument.
Background technology
Thoracic duction instrument conventional at present generally has fluid collection chamber, water seal cavity and pressure regulating cavity three cavitys, the hydrops that fluid collection chamber is removed in order to store thoracic cavity, water seal cavity is in order to separating atmospheric pressure, pressure regulating cavity is filled into the size of water rate control captivation wherein by adjustment, this kind of drainage system Problems existing be in thoracic cavity the short time discharge a large amount of gas and measure its amount size, pulmonary is easily caused suddenly to open again and cause complex metalwork when directly using attractor to carry out imbibition when breast intracavity gas does not drain, the inducement of complex metalwork is that lung recruitment speed is too fast, chest drainage (aerofluxus, discharge opeing) excessive velocities, disposable amount is excessive, so even jeopardize the sick safety of patient, result of use is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of rational in infrastructure, is convenient to the thoracic duction instrument intuitively showing thoracic cavity capacity.
For realizing the object of this utility model, being achieved by the following technical solutions: a kind of thoracic duction instrument, including fluid collection chamber, water seal cavity and pressure regulating cavity that side integrally connects successively; Be connected with flow sub above described fluid collection chamber and be communicated with joint; Be connected with water sealing (sealing water) pipe above described water seal cavity, water sealing (sealing water) pipe lower end reaches bottom water seal cavity, is communicated with between joint and water sealing (sealing water) pipe and is connected with communicating pipe; Be connected with liquid-feeding tube above described pressure regulating cavity and attract joint, liquid-feeding tube lower end reaches bottom pressure regulating cavity, is also connected with gas-storing bag connection tube above described water seal cavity, gas-storing bag connection tube is connected with a gas-storing bag; A vent valve is connected with by pipeline between above described water seal cavity and pressure regulating cavity.
Preferably: described gas-storing bag is soft plastic film molding, the capacity of gas-storing bag is 150-200ml.
Preferably: be positioned in described fluid collection chamber immediately below flow sub and be also connected with a hydrops cup.
Preferably: the pipeline of described gas-storing bag connection tube is connected with an air valve.
Compared with prior art, the beneficial effects of the utility model are: by connecting a gas-storing bag on water seal cavity, can be stored in gas-storing bag when having gas to discharge in thoracic cavity, the capacity of gas-storing bag is determined value, after filling gas Deng gas-storing bag, open vent valve by the evacuate air in gas-storing bag, then close vent valve again, this makes it possible to the number knowing chest Exhaust Gas comparatively accurately; In addition, when the outer gravitational attraction of needs, be connected on negative pressure source by attraction joint, now open vent valve, gas-storing bag can not impact attraction, very easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1, fluid collection chamber; 11, interior hydrops cup; 12, joint is communicated with; 13, flow sub; 2, water seal cavity; 21, water sealing (sealing water) pipe; 22 gas-storing bag connection tubes; 3, pressure regulating cavity; 31, liquid-feeding tube; 32, joint is attracted; 5, communicating pipe; 6, gas-storing bag; 7, vent valve; 8, air valve.
Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to Fig. 1, a kind of thoracic duction instrument described in the present embodiment, includes fluid collection chamber 1, water seal cavity 2 and pressure regulating cavity 3 that side integrally connects successively; Be connected with flow sub 13 above described fluid collection chamber and be communicated with joint 12; Be connected with water sealing (sealing water) pipe 21 above described water seal cavity, water sealing (sealing water) pipe lower end reaches bottom water seal cavity, is communicated with between joint and water sealing (sealing water) pipe and is connected with communicating pipe 5; Be connected with liquid-feeding tube 31 above described pressure regulating cavity and attract joint 32, liquid-feeding tube lower end reaches bottom pressure regulating cavity, is also connected with gas-storing bag connection tube 22 above described water seal cavity, gas-storing bag connection tube is connected with a gas-storing bag 6; A vent valve 7 is connected with by pipeline between above described water seal cavity and pressure regulating cavity.
Described gas-storing bag is soft plastic film molding, and the capacity of gas-storing bag is 150-200ml.
Be positioned in described fluid collection chamber immediately below flow sub and be also connected with a hydrops cup 11.The hydrops that thoracic cavity is discharged first flow in interior hydrops cup through flow sub, and interior hydrops cup overflows in fluid collection chamber after having expired again, is convenient to the color state change observing hydrops like this.
The pipeline of described gas-storing bag connection tube is connected with an air valve 8.
By connecting a gas-storing bag on water seal cavity, can be stored in gas-storing bag when having gas to discharge in thoracic cavity, the capacity of gas-storing bag is determined value, after filling gas Deng gas-storing bag, open vent valve by the evacuate air in gas-storing bag, then close vent valve again, this makes it possible to the number knowing chest Exhaust Gas comparatively accurately; In addition, when the outer gravitational attraction of needs, be connected on negative pressure source, now open vent valve by attraction joint, as long as close the air valve 8 on gas-storing bag connection tube pipeline, gas-storing bag would not impact attraction, very easy to use.
