The patent No. is that 02233663.X, publication number are the Chinese utility model patent of CN201164465Y, a kind of mobile drainage type vital capacity detecting device is disclosed, include the pipeline that leads to the top is installed in casing, the casing, gate valve is housed and the bucket of blowing on the pipeline, casing is provided with gate valve and scale etc.During use gate valve is opened, closed again after the fills with water, when the measured blocks inflatable mouth with mouth, open gate valve simultaneously, after having surveyed, rapid closing gate valve, scale can show measured's vital capacity.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, not spilling water, test educational observation tangible spirometer.
For achieving the above object, the technical solution adopted in the utility model is:
Spirometer is used in a kind of test teaching, comprising: outer bucket, and the bottom center of outer bucket is connected with vertical draft tube, and the bottom of draft tube is connected with gas blow pipe, and the other end of gas blow pipe is connected with blow gun; The bottom of outer bucket is fixed with leg, and set screw is installed on the leg, and the bottom of outer bucket is connected with draining valve; In the outer bucket keg float is housed, it is characterized in that: be connected with expansion link on the outside bucket wall of outer bucket, the head end of expansion link is connected with support, and the two ends of support are equipped with pulley; The middle part of support is connected with the blow gun seat; The both sides at keg float top are connected with hanger respectively, have fastened stay cord on the hanger, and the other end of stay cord passes pulley and is connected with balance bob; The top of keg float is equipped with air release; Design has scale mark on the outer wall of keg float.
The utility model is simple in structure, spilling water, test educational observation are unobvious.Because spilling water has not been avoided unexpected injury, has reduced the trouble that adds water more yet.
Description of drawings
Fig. 1 is perspective view of the present utility model (a keg float full state).

In the accompanying drawing: 1, pulley; 2, stay cord; 3, keg float; 4, balance bob; 5, gas blow pipe; 6, outer bucket; 7, leg; 8, set screw; 9, draining valve; 10, hanger; 11, air release; 12, blow gun seat; 13, support; 14, blow gun; 15, draft tube; 16, scale mark.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model test teaching comprises with spirometer as shown in Figure 1: outer bucket 6, and the bottom center of outer bucket 6 is connected with vertical draft tube 15, and the bottom of draft tube 15 is connected with gas blow pipe 5, and the other end of gas blow pipe 5 is connected with blow gun 14.The bottom of outer bucket 6 is fixed with three legs 7, on each leg 7 set screw 8 is installed, and the utility model uses the verticality of the outer bucket of three set screw adjustment and surface level.The bottom of outer bucket 6 is connected with draining valve 9.
In the outer bucket 6 keg float 3 is housed.Be connected with expansion link on the outside bucket wall of outer bucket 6, the head end of expansion link is connected with support 13, and the two ends of support 13 are equipped with pulley 1, and the middle part of support 13 is connected with blow gun seat 12.
The both sides at keg float 3 tops are connected with hanger 10 respectively, have fastened stay cord 2 on the hanger 10, and the other end of stay cord 2 passes pulley 1 and is connected with balance bob 4, and balance bob 4 is used to make keg float 3 balances to rise.The top of keg float 3 is equipped with air release 11; Design has scale mark 16 on the outer wall of keg float 3, writes down the size of this vital capacity.
Operation instruction of the present utility model:
The utility model test teaching is mainly used in the physiological test teaching with spirometer, mainly measures the size of vital capacity, so that measure the size of pulmonary function, reflects the functional status of health thus.
The utility model mainly is made up of a pair of drum that is nested together: outer barreled is gone into a certain amount of clear water, and water discharging valve is arranged at the bottom, and there is draft tube in central authorities, surfaces in the upper end of pipe, and the pipe lower end connects leads to the outer gas blow pipe of bucket, and tidal air is come in and gone out through this.Interior bucket is an airtight space in the keg float for tipping upside down on the keg float in the outer bucket, and keg float can the lifting with the turnover of breathing gas.
When the student tests again, earlier downwards by inner keg float, an amount of water between inside and outside two-layer metal bucket again.Blow with blow gun, float to corresponding scale mark on the inboard keg float, write down the size of this vital capacity.
Single test is finished, and inner keg float be pressed, and waits for test for the second time.Sometimes the interior water of outer bucket is overflowed during test, make ground wet and slippery, classmates are fallen down, cause unnecessary damages.
Make the main cause that water overflows be in the experiment: in the time of in the student is blown into gas in bucket, gas makes the keg float come-up, and down on time, because keg float has the gas that blows, gas can't get out again, and the actual water that is gas is oppressed in the bucket overflows.
Water when testing in order to make in the outer bucket does not overflow, and the utility model is installed air release 11 at the top of keg float 3, during test air release 11 cuts out, and keg float 3 is still an airtight space in water like this, does not influence test effect.After test is finished, air release 11 is opened, gas is discharged from valve, presses under the keg float again, does not just have water and does not overflow from outer bucket, has avoided unexpected injury, has also reduced the trouble that adds water again, and this is the design of a kind of hommization of considering for the student.
