Description
Technical field
The utility model is related to field of medical technology, more particularly to a kind of PFT breathing teaching mould.
Background technology
Respiratory tract that human body respiration model of the prior art includes being simulated with tracheae, the thoracic cavity simulated with bottle and
The lung simulated with balloon, teacher can only be blown into or suck gas with tracheae, so as to cause in human body respiratory is introduced
The balloon for simulating lung stretched and relaxed explains human body respiration process.
But above-mentioned model not only complex operation, it is necessary to demonstrator carry out expiration operation, and the model can't image
Embodiment breathing feature.
In summary, need a kind of PFT for overcoming above-mentioned technical problem of design badly at present and breathe teaching mould.
Utility model content
The purpose of this utility model there is provided a kind of PFT breathing teaching mould, the demonstration that it not only can be vivid
PFT respiratory, and with it is easy to operate, ingenious in design the characteristics of.
To achieve these goals, the utility model is adopted the technical scheme that：A kind of PFT breathes teaching mould,
Including bottle, the top of the bottle is divided into bucket-shaped, and bottom is divided into pillar buoy；The upper part of the bottle has
One opening；Also include the piston rod and two balloons in the bottle used cooperatively with the pillar buoy；
Also include an inverted Y-shaped three-way pipe, the supervisor of the three-way pipe is connected with the opening and passes the opening, its
It is tightly connected with the side wall of opening；Two branch pipes of the three-way pipe are connected and close between its side wall with the inflatable mouth of balloon respectively
Envelope connection；
One end of the piston rod passes the pillar buoy and is connected with the push handle in outside.
A kind of PFT breathing teaching mould as described above, wherein, the pillar buoy accounts for two points of the bottle height
One of；Scale value of the lateral wall of the pillar buoy provided with sign pressure value.
A kind of PFT breathing teaching mould as described above, wherein, outside the port of each branch pipe of the three-way pipe
Side wall is integrated with opening or balloon and is connected.
A kind of PFT breathing teaching mould as described above, wherein, the bottle is made of the transparent plastic of hard.
A kind of PFT breathing teaching mould as described above, wherein, the three-way pipe is made of silicone tube.
Compared with prior art, the beneficial effect that the utility model is produced is mainly reflected in：
1st, a kind of PFT breathing teaching mould of the present utility model, it controls the air pressure in bottle by piston, so that
Make balloon stretched and relaxed to react the respiratory of PFT；
2nd, a kind of PFT breathing teaching mould of the present utility model, it holds piston rod and pushed away when operation
Enter or pull out, so as to adjust the pressure value in bottle；
3rd, a kind of PFT breathing teaching mould of the present utility model, it has simple in construction, convenient use, demonstrating effect
Good the characteristics of, the feature that more vivid embodiment is breathed.
Brief description of the drawings
Fig. 1 is the structural representation that a kind of PFT of the present utility model breathes teaching mould；
Description of reference numerals：
1st, bottle 2, pillar buoy 3, opening
4th, piston rod 5, balloon 6, three-way pipe

Embodiment
, now will be in conjunction with the embodiments to this practicality for the ease of understanding the purpose of this utility model, technical scheme and its effect
It is new to be elaborated further.
As shown in figure 1, a kind of PFT breathing teaching mould of the present utility model, including bottle 1, the bottle 1 it is upper
Part is bucket-shaped, and bottom is divided into pillar buoy 2；The upper part of the bottle 1 has an opening 3；Also include and the pillar buoy 2
The piston rod 4 used cooperatively and two balloons 5 in the bottle 1；Also include an inverted Y-shaped three-way pipe 6, described three
The supervisor of siphunculus 6 be connected with the opening 3 and pass it is described be open 3, the side wall of itself and opening 3 is tightly connected；The three-way pipe 6
Two branch pipes connect and be tightly connected between its side wall with the inflatable mouth of balloon 5 respectively；One end of the piston rod 4 passes institute
State pillar buoy 2 and be connected with the push handle 7 in outside.
A kind of PFT breathing teaching mould of the present utility model, it is during operation, and demonstrator holds the piston
The push handle 7 of bar 4 carries out pulling operation, so that the pressure value in bottle 1 reduces, and balloon 5 is increasing in the presence of external pressure
Greatly；It is on the contrary then promote push handle 7, then the pressure value increase in bottle 1, and balloon 5 is internally gradually becoming in the presence of pressure
It is small；The balloon 5 it is stretched and relaxed, the respiratory of PFT can be clearly showed that, be easy to student to understand.
As shown in figure 1, a kind of PFT breathing teaching mould of the present utility model, it is high that the pillar buoy 2 accounts for the bottle 1
/ 2nd of degree；Scale value 8 of the lateral wall of the pillar buoy 2 provided with sign pressure value.
A kind of PFT breathing teaching mould of the present utility model, the pillar buoy 2 is used for the motion for operating piston, so as to control
The size of pressure value in bottle body 1.
As shown in figure 1, a kind of PFT breathing teaching mould of the present utility model, each branch pipe of the three-way pipe 6
The lateral wall of port is integrated and is connected with opening 3 or balloon 5；In order to prevent sealing problem, then three-way pipe 6 and it will be connected thereto
Object between be integrally connected.
As shown in figure 1, a kind of PFT breathing teaching mould of the present utility model, the bottle 1 is transparent using hard
Plastics are made；The relaxation of internal balloon 5 is checked so as to facilitate student to understand, is easy to it to understand.
As shown in figure 1, a kind of PFT breathing teaching mould of the present utility model, the three-way pipe 6 uses silica gel control
Into.
Further narration has been done to the utility model above in conjunction with embodiment, but the utility model is not limited to above-mentioned reality
Apply in mode, the knowledge that one skilled in the relevant art possesses, the utility model objective can also not departed from
On the premise of make a variety of changes.
