Specific embodiment
Referring to Figures 1 and 2, the utility model, that is, a kind of pulse type liquid generating device, by transmission mechanism and piping installation
Two parts composition, wherein transmission mechanism includes motor 1, and the output shaft and pinion gear 2 of motor 1 are connected, pinion gear 2 and driven wheel 3
It is meshed, driven wheel 3 is connected with piston rod 4；Piping installation includes seat 7 in water valve, and tail portion is equipped with water valve back seat 6, the two shape
At a blister cavities, front side is equipped with water valve front stall 8.
As a kind of preferred structure of the present embodiment, vacancy is embedded in fixed column, upper perimeter setting in the driven wheel 3
Cylindrical protrusions are arranged in meshing gear, lower section side.
As a kind of preferred structure of the present embodiment, the piston rod 4, bar portion has certain length, and a side end is in
Flat O-ring shape, flat O-ring shape structure insertion 3 lower cylindrical of the driven wheel protrusion, end side connect with two sealing rings 5
It connects.
As a kind of preferred structure of the present embodiment, setting water inlet port 6-1 above the water valve back seat 6, intake port
Inlet valve 9 is equipped at 6-1, lower section is equipped with insertion piston rod 4 and guarantees the extension pipeline that piston rod 4 freely moves back and forth.
As a kind of preferred structure of the present embodiment, 7 front end of seat is equipped with flowing water Valve 10 in the water valve.
As a kind of preferred structure of the present embodiment, 8 end of water valve front stall is equipped with a water outlet port 8-1.
As a kind of preferred structure of the present embodiment, the water valve front stall 8 can be equipped with a water outlet port 8-1 and one
A vacuum suction port 8-2.
As a kind of preferred structure of the present embodiment, the inlet valve 9 is in umbrella, and shank and water inlet port 6-1 are solid
Even, umbrella portion is set in blister cavities.
As a kind of preferred structure of the present embodiment, the flowing water Valve 10 is in umbrella, 7 front side of seat in shank and water valve
It is connected, umbrella portion is disposed far from blister cavities side.
Because pulse lavage has pressurization phase and decompression phase per liquid stream between one pulse at it, make to be rinsed group when being woven in different
Phase back and forth generates contraction and diastole campaign, accelerates foreign matter between tissue and loosens, so that latent foreign matter within the organization, carefully
Bacterium, trifling and hemotoncus etc. are detached from tissue surface because of trembling, are rinsed liquid and wash away, to reach the purpose of thorough debridement.Motor 1
Output shaft drives pinion gear 2 to rotate several circles, so that driven wheel 3 completes one circle of rotation and forms a complete period movement, at it
In first half cycle motion process, referred to as pressurization phase, driven wheel 3 drive piston rod 4 to move to blister cavities direction, are formed just in blister cavities
Pressure, 9 umbrella portion of inlet valve is because hydraulic pressure closes water inlet, and the umbrella portion for the flowing water Valve 10 that 7 front end of seat is arranged in water valve is because of hydraulic pressure
And be rushed to open, so the liquid flow with certain pressure is by blister cavities through 7 front end water outlet of seat, 8 inner tube of water valve front stall in water valve
Road and water outlet port 8-1 and spray head, eject the pulse liquid flow of certain shapes；In its first half cycle motion process,
It referred to as depressurizes the phase, driven wheel 3 drives piston rod 4 to move to far from blister cavities direction, negative pressure is formed in blister cavities, in water valve before seat 7
The umbrella portion of flowing water Valve 10 of setting is held to close its water outlet due to hydraulic pressure, the umbrella portion of inlet valve 9 is because negative pressure is by water inlet
It opens, outside liquid enters blister cavities through water inlet port 6-1, and liquid will be filled with blister cavities at this time.Since pressurization phase and decompression phase are close
Alternately, interval time is shorter, therefore sustainable formation pulse type liquid rinses water flow, this flushing liquor is acted on wounds
Position can reach ideal clinical debridement effect.In addition, water valve front stall 8, which can be used, only has Sing plus liquid water outlet port 8-1
Design scheme, the design scheme for having both pulse liquid water outlet port 8-1 Yu vacuum suction port 8-2, Hou Zheke also can be used
It is realized while the pulse lavage surface of a wound and is removed flushing waste, rinse and attract one, clinical debridement effect is good and cleaning is imitated
Rate is high.At the same time, by the way that 1 different operating voltage of motor is arranged or continuously adjusts its operating voltage during the work time,
It can be according to patient's difference surface of a wound clinical practice it is required that the pulse liquid pressure of output is continually and steadily in a certain numerical value, or at certain
It is arbitrarily adjusted in one range.
