Description
Technical field
The present invention relates to a kind of medical catheter leak-checking apparatus, whether jagged for the blind end detecting medical catheter.
Background technology
The electric elements such as electrode, circuit board are equipped with in the inside of medical catheter as PH conduit, for measuring the potential of hydrogen of human gastric juice.If the blind end of medical catheter is jagged, gastric juice can enter in medical catheter, not only easily causes short circuit, and can destroy gastric juice potential of hydrogen, likely damages health.Therefore, whether the blind end measuring medical catheter leaks and is necessary very much.At present, detect medical catheter and generally adopt plastic bottle product to seal, the product other end exposes plastic bottle closure, and this sealing effectiveness that leaks hunting is not good, and not only inconvenient operation, detection time is long, and detection efficiency is low, and testing result is inaccurate.
Summary of the invention
Because the above-mentioned defect of prior art, technical matters to be solved by this invention is to provide a kind of medical catheter leak-checking apparatus.
Technical solution of the present invention is as follows: a kind of medical catheter leak-checking apparatus, it is characterized in that: on the side of sealing cylinder, the cylinder that is filled with water is set, the top of sealing cylinder is installed and is promoted cylinder, the rod chamber promoting cylinder is all connected with pneumatic control valve by tracheae with rodless cavity, piston rod and the push pedal of described promotion cylinder fix, the plate face of push pedal towards sealing cylinder is installed sealing depression bar, sealing depression bar is hollow tubular structures, sealing depression bar is perpendicular to push pedal, push pedal just has via hole to the position of sealing depression bar, sealing cylinder casing wall just has pilot hole to the position of sealing depression bar, setting-in sealing shroud in this pilot hole, sealing shroud is inwardly spacing by the step surface of pilot hole inwall, after the compressing of sealing depression bar, described sealing shroud can expand center pit and diminish, external diameter becomes large.
Adopt above technical scheme, when detection, first the opening end of medical catheter is passed via hole, the sealing center pit of depression bar and the center pit of sealing shroud in push pedal, the opening end of medical catheter is made to stretch in sealing cylinder, and the blind end of medical catheter is put into and is filled with water in cylinder, and under being positioned at liquid level; Then pneumatic control valve is opened, the piston rod of promotion cylinder is made to drive push pedal to move to sealing shroud direction together with sealing depression bar, sealing depression bar applies pressure to sealing shroud, because sealing shroud can not be subjected to displacement in sealing cylinder, therefore sealing shroud pressurized expands distortion, and the center pit of sealing shroud diminishes, medical catheter is held tightly, meanwhile, the external diameter of sealing shroud becomes large, by the clearance seal between sealing shroud and sealing cylinder pilot hole hole wall; Then in sealing cylinder, be filled with the pressurized air of certain pressure, compress the medical catheter be enclosed in sealing cylinder, if the blind end of medical catheter is jagged, gas can be pressed in medical catheter and spill from blind end breach, medical catheter has gas to spill can emit bubble in water, the jagged gas leakage of this medical catheter sealed end part is then described, medical catheter is defective, otherwise then medical catheter is air tight qualified.
Piston rod and the location-plate of described promotion cylinder fix, and location-plate mounts push pedal, and the lower end of push pedal is equipped with a row and is sealed depression bar, and the distance between two adjacent sealing pressing bars is equal.Above structure is not only conducive to push pedal dismounting, push pedal is installed firm, and disposablely can detect many medical catheters, substantially increase detection efficiency.
Installing firmly to seal depression bar, avoiding it to occur to loosen or come off, make one end of described sealing depression bar embed in push pedal, both wringing fits.
In order to simplify structure, facilitating processing and fabricating, reducing production cost, described in the cylinder that is filled with water be uncovered square in upper end.
In like manner, described sealing cylinder is square.
For the ease of processing and assembling, the fixing holding medical catheter after making sealing shroud be subject to compression swelling tightly is good, sealing effectiveness is more remarkable, on described sealing cylinder casing wall just to sealing depression bar pilot hole be clear opening, described sealing shroud is positioned at pilot hole one end away from sealing depression bar, the hole wall clearance fit of sealing shroud and pilot hole.
Beneficial effect: structure of the present invention is simple, assembling is easy, it is little to take up room, cost is low, good sealing effect during detection, and sealing effectiveness can be regulated by the stroke of adjustment promotion cylinder, different detection needs can be met, guaranteeing that testing result is accurately, simultaneously reliably, simple, convenient, quick, the disposable detection realizing eight even more more number medical catheters, detection time is short, and detection efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the layout schematic diagram of sealing depression bar and sealing shroud.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1 and Figure 2, sealing cylinder 1 is preferably square, and sealing cylinder 1 has air-filled pore, and this air-filled pore is connected to gas-filled tube, and gas-filled tube is connected after air valve and rain glass 9, is connected with source of the gas.At sealing cylinder 1 as illustrated left side arranges the cylinder 2 that is filled with water, the cylinder 2 that is filled with water is preferably uncovered square in upper end, is filled with water cylinder 2 and sealing cylinder 1 closely.Install at the top of sealing cylinder 1 and promote cylinder 3, the rod chamber promoting cylinder 3 is all connected with pneumatic control valve 4 by tracheae with rodless cavity, and the motion promoting cylinder 3 piston rod is controlled by pneumatic control valve 4.
As shown in Figure 1 and Figure 2, the piston rod promoting cylinder 3 left level stretches out, and to fix with location-plate 8, promotes the piston rod of cylinder 3 perpendicular to location-plate 8.Be provided with push pedal 5 in the left side of location-plate 8, push pedal 5 is positioned at the top of the cylinder 2 that is filled with water.Push pedal 5 and location-plate 8 fit, and are bolted between the two.The lower end of push pedal 5 exceeds the bottom surface of location-plate 8, and on the plate face of sealing cylinder 1, arrange a row in push pedal 5 lower end and seal depression bar 6, all sealing depression bars 6 are positioned in same level, and the distance between two adjacent sealing pressing bars 6 is equal.Sealing depression bar 6 is hollow tubular structures, and sealing depression bar 6 is perpendicular to push pedal 5, and the left end of sealing depression bar 6 embeds in push pedal 5, both wringing fits.The number of sealing depression bar 6 is determined according to actual needs, and the present embodiment is preferably 8.Push pedal 5 just has via hole 5a to the position of sealing depression bar 6, and the center line of via hole 5a is positioned on straight line with the corresponding axial line sealing depression bar 6, and via hole 5a is communicated with the corresponding center pit sealing depression bar 6.Sealing cylinder 1 left end casing wall just has pilot hole to the position of sealing depression bar 6, this pilot hole is clear opening, the right-hand member of sealing depression bar 6 stretches in corresponding pilot hole, and the right-hand member setting-in sealing shroud 7 in each pilot hole, the hole wall clearance fit of sealing shroud 7 and pilot hole, sealing shroud 7 is spacing by the step surface of pilot hole inwall to the right.
