Therefore, the structural form that the air inlet pipe is constantly inserted in the water, the air outlet pipe encircles the liquidoid bubble observing tube, and ventilation points spread all over the two ends of the liquidoid bubble observing tube is constituted.
Description
Technical field
The present invention relates to a kind of intelligent liquid phase bubble flowmeter amount viewer.Be adapted at promptly can not Direct observation infusing, transfuse blood and drip under the situation of speed under pressure transfusion, the blood transfusion state,, just know transfusion speed through observing the bubble flow of pressure source, thus rescue and treatment under the completion complex situations.
Background technology
Liquid phase bubble flowmeter amount viewer now is main with the gravity float-type, promptly in the sight glass pipe, float is set, and when gas passed through, float was upwards floating, learns the gas flow that passes through through the floating height of measuring float.What it was not enough is: can only vertically use, under the situation that keeps flat, puts upside down, can't use, not be suitable for complicated occasions such as field, battlefield, disaster scene, 120 first aids.
Summary of the invention
The objective of the invention is to propose a kind of simple in structure, feasible, adapt to the intelligent liquid phase bubble flowmeter amount viewer under the various complex environments.
Intelligent liquid phase bubble flowmeter amount viewer of the present invention comprises: loam cake, housing, following inner cap, lower cover, sealing cap, water liquid and three one-way ventilating films (going up one-way ventilating film, one-way ventilating film and following unidirectional ventilated membrane) are formed.Wherein the one-way ventilating film be separately positioned between loam cake and the housing, down between inner cap and the lower cover, between the draft tube lower end and sealing cap of lower cover.Loam cake and housing, following inner cap and the airtight bonding of housing, airtight bonding between the draft tube hypomere of lower cover and housing, lower cover and the sealing cap.There is the gas outlet that upwards stretches out at the loam cake center; Last air channel is arranged below the loam cake and be communicated with the gas outlet that upwards stretches out.Housing is that major diameter, periphery are that the short tube body of several minor diameters, intervalve are liquid phase bubble observation tube in the middle of being, several narrow tubes of periphery are air communicating pipe.The upper surface of liquid phase bubble observation tube is provided with the capping of porous.Following inner cap is the center cover plate all porose with periphery, the airtight bonding in lower end of its periphery and liquid phase bubble observation tube, the airtight bonding of root of the draft tube that upwards stretch out at center pit and lower cover center; Following air channel is arranged above the lower cover; There is the draft tube of stretching out up and down respectively at the lower cover center, its part of stretching out downwards and the airtight bonding of sealing cap, and the operative tip that upwards stretches out extends the center position of liquid phase bubble observation tube; In liquid phase bubble observation tube, inject about 70% water liquid, because all there is one-way ventilating film (going up one-way ventilating film and one-way ventilating film) at its two ends, so water liquid remains total amount in liquid phase bubble observation tube constant.Like this, just constituted draft tube and be inserted in all the time in the water liquid, escape pipe is around around the liquid phase bubble observation tube, and ventilative point spreads all over the version at liquid phase bubble observation tube two ends.
Gas passes down unidirectional ventilated membrane from the lower end of sealing cap; Get into liquid phase bubble observation tube through the draft tube that covers down; Gas gets into its upper space with bubble form through the water liquid in the liquid phase bubble observation tube, and last air channel below last one-way ventilating film, loam cake and gas outlet are upwards discharged again.And when intelligent liquid phase bubble flowmeter amount viewer of the present invention in any morpheme in the time of (as tilting, putting upside down); The draft tube entering liquid phase bubble observation tube that gas still passes down unidirectional ventilated membrane from the lower end of capping, covers down; Pass water liquid and get into its upper space, different is gas will be through the following unidirectional ventilated membrane between inner cap and the lower cover down, the following air channel above the lower cover, the air communicating pipe on the housing, last air channel and the gas outlet discharge at loam cake center below the loam cake.
So intelligent liquid phase bubble flowmeter amount viewer of the present invention has following advantage: the flow that, can reflect gas intuitively through the flow of metering bubble; Two, under the situation that is used for pressure transfusion, blood transfusion, can come to reflect intuitively the flow velocity and the flow of transfusion through the metering gas flow; Three, practicality simple for structure is easy to utilize.
Description of drawings
Fig. 1 is an assembly structure synoptic diagram of the present invention.
Fig. 2 is a section of structure of the present invention.
Embodiment
Intelligent liquid phase bubble flowmeter amount viewer shown in Figure 1 is made up of loam cake 1, last one-way ventilating film 2, housing 3, following inner cap 4, one-way ventilating film 2A, lower cover 5, following unidirectional ventilated membrane 2B, sealing cap 6 and water liquid 7.
Shown in Figure 2; During use; Gas gets into from the following stomidium 6a of sealing cap 6, passes down unidirectional ventilated membrane 2B, and the draft tube 5a on lower cover 5 gets into liquid phase bubble observation tube 3a; Gas gets into its upper spaces with bubble form through the water liquid among the liquid phase bubble observation tube 3a 7, again last air channel 1b and the upwards discharge of gas outlet 1a below last one-way ventilating film 2, loam cake 1.
When intelligent liquid phase bubble flowmeter amount of the present invention, viewer in morpheme arbitrarily in the time of (as tilting, putting upside down); Gas still gets into from the following stomidium 6a of sealing cap 6; Pass down unidirectional ventilated membrane 2B; Draft tube 5a on lower cover 5 gets into liquid phase bubble observation tube 3a; Pass water liquid 7 and get into its upper spaces, different is gas will be through the following last air channel 1b of the one-way ventilating film 2A between inner cap 4 down and the lower cover 5, the following air channel 5b above the lower cover 5, air communicating pipe 3b, loam cake 1 on the housing 3 and the gas outlet 1a discharge at loam cake 1 center.
Like this, the flow velocity and the flow of gas easily observed, measure to intelligent liquid phase bubble flowmeter amount of the present invention, viewer can easily under various complicated occasions.
