Abstract

The utility model relates to a portable bidirectional vital capacity measuring instrument, which is characterized by comprising two measuring bottles and a communicating device, wherein the measuring bottles have the same volume and structure and each measuring bottle is provided with a blowing device; the communicating device is communicated with the measuring bottle; the two measuring bottles are internally provided with liquid with the same volume and are sealed by soft plugs respectively; each bottle body is provided with a measuring ruler; each blowing device comprises a blowing hopper, a blowing hose and a blowing glass pipe that are sequentially inserted with one another; the blowing hopper and the blowing hose are arranged outside the measuring bottle; and the communicating device comprises a bridge-type communicating pipe and a rotatable check valve. The portable bidirectional vital capacity measuring instrument has the advantages of having a low cost, facilitating popularization and application, being used for students and wider groups such as families, athletes and the like, having a compact structure, being manufactured easily, being used conveniently, being used bidirectionally, and being capable of replacing the blowing hopper so as to be used by only one user, thereby avoiding cross infection.

Description

A kind of easy two-way vital capacity measuring instrument

Technical field

This utility model relates to a kind of instrument of measuring body constitution, relates in particular to a kind of easy two-way vital capacity measuring instrument, belongs to the medical detecting Instrument technical field.

Background technology

At present, the annual health check-up of students in middle and primary schools is all the project of measurement vital capacity as a necessary check, and existing vital capacity detecting instrument, complex structure costs an arm and a leg, and is not easy to extensively promote the use of.Wider crowds such as some family and athlete also wish often to detect the vital capacity of oneself, as a kind of foundation of health indicator and train on; Therefore need be a kind of simple in structure, low price, novel vital capacity measuring instrument easy to use.

Summary of the invention

This utility model purpose is to have vital capacity measuring instrument complex structure now in order to improve, and costs an arm and a leg, and the problem that is not easy to extensively promote the use of has proposed a kind of easy vital capacity measuring instrument, is intended to improve the range of application of vital capacity measuring instrument, and reduces use cost.

Technical solution of the present utility model is achieved in that

A kind of easy two-way vital capacity measuring instrument is characterized in that, it comprises that two volume structures are the same and has the measurement bottle of blowning installation and in order to be communicated with the described communication apparatus of measuring bottle;

The described liquid that equal volume is housed in the bottle of measuring also seals with cork respectively, and body is provided with surveyors' staff;

Described blowning installation comprises successively air blowing bucket, air blowing flexible pipe and the air blowing glass tubing of pegging graft, and described air blowing bucket and air blowing flexible pipe are positioned at outside described the measurements bottle, and described gas blow pipe was inserted described cork, and to enter described measurements bottle interior and be positioned at more than near the liquid level of bottleneck;

Described communication apparatus comprises bridge-type communicating pipe and can change check valve, described bridge-type communicating pipe is communicated with into an integral body by two 90 degree bend pipes by the described check valve that changes, and the two ends of described bridge-type communicating pipe were inserted described cork respectively and entered two and measure in the bottle and be positioned at below the liquid level.

Compared with prior art, the beneficial effects of the utility model are:

1, cost is low, is convenient to promote the use of, and not only can be used for the student, also can be used for wider crowds such as family and athlete;

2, compact conformation, making easily;

3, easy to use, can two-wayly use, the bucket of blowing is replaceable, thereby can accomplish special messenger's special use, has avoided cross infection.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure, 1, the bucket I that blows, 2, air blowing flexible pipe I, 3, air blowing glass tubing I, 4, measure a bottle I, 5, cork I, 6, surveyors' staff I, 7, can change check valve, 8, communicating pipe, 9, surveyors' staff II, 10, cork II, 11, measure a bottle II, 12, air blowing glass tubing II, 13, air blowing flexible pipe II, 14, bucket II blows.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described:

As shown in Figure 1, a kind of easy two-way vital capacity measuring instrument, comprising blow bucket I1, flexible pipe I2, glass tubing I3, measure bottle I4, cork I5, a surveyors' staff I6, can change check valve 7, communicating pipe 8, surveyors' staff II9, cork II10, measure bottle II11, a glass tubing II12, flexible pipe II13, bucket II14 blows, it is characterized in that described flexible pipe I2 one end socket glass tubing I3, another termination air blowing bucket I1; After sealing was inserted with the end of glass tubing I3 and communicating pipe 8 respectively on the cork I5, jam-pack was encapsulated into the bottleneck of measuring bottle I4; Measure bottle I4 and be provided with surveyors' staff I6; Communicating pipe 8 is provided with can change check valve 7; After sealing was inserted with the other end and glass tubing II12 of communicating pipe 8 respectively on the cork II10, jam-pack was encapsulated into the bottleneck of measuring bottle II11; Measure bottle II11 and be provided with surveyors' staff II9; Flexible pipe II13 one end socket glass tubing II12, another termination air blowing bucket II14.Can two-wayly use, two buckets of blowing can be changed.

Wherein can change check valve 7, its check valve handle can Rotate 180 °, can enter into and measures bottle II or enter into and measure a bottle I one-way flow from measuring a bottle II from measuring a bottle I with Informal water.

During measurement, measure the water that respectively injects half volume in the bottle with two, can change check valve 7 forwards to from measuring bottle I to the direction of measuring bottle II one-way flow, the measured blows toward measuring in the bottle I4 from the bucket I1 that blows, hydraulic pressure is gone into to enter communicating pipe 8 to measure bottle II11, after the measured stopped to blow, surveyors' staff I6 or surveyors' staff II9 can show measured's vital capacity.Next measured can change check valve 7 and forward to from measuring bottle II to the direction of measuring bottle I one-way flow, make two waters of measuring bottle etc. earlier, begin to measure as mentioned above again.

Claims
