Definitions
- the present invention patent application is included within the field of medicine and more specifically in the field of control of the proper functioning or testing of an endoscope, said control focusing on the detection of possible leaks that may occur therein.
- the present invention relates to a leak control device of an endoscope that is connected in the operation section of the endoscope at the proximal end thereof.
- the present device is characterized in that it comprises a valve for connecting the device to the endoscope, connecting it to the end of a tubular outer casing which disposes at the opposite end of an inner, also tubular plunger of dimensions and shape such that it travels in the interior of the housing, according to a direction parallel to the axis of revolution of the housing and the plunger itself in one way, the said plunger having a test line perpendicular to the axis of revolution thereof, said line being located at a certain distance from the free end of the plunger.
- valve of the device will be connected to one of the inlet openings of the endoscope, the sealing will be sealed and once achieved, a displacement of the embolus will be carried out with respect to the housing, so that a suction effect is carried out by extracting part of the existing air inside the endoscope or by blowing air into the endoscope.
- Said operation may be performed once or several times depending on the relative size between the endoscope and the embolus, that is, depending on the amount of air volume that the device is capable of driving in each case. Once certain pressure conditions have been reached inside the endoscope, the piston will stop acting and the test line will be observed.
- Figure 1 represents a perspective view of the endoscope to which the device object of the present invention has been coupled.
- Figure 2 represents a larger scale view of the endoscope area to which the device is connected, when said device is connected.
- Figure 3 represents a perspective view of the device object of the present invention in rest position.
- Figure 4 represents a perspective view of the device object of the present invention in the driving position when pressure is exerted on the plunger. Description of a preferred embodiment
- Figure 1 shows a general perspective view of an endoscope (1) to which the control device object of the present invention is connected through a connection valve (2) to a mouth (8) of the endoscope located in the operation section thereof.
- connection valve (3) as can be seen in Figure 3 for example, in the present preferred embodiment, consists of a kind of circular nut, which is internally threaded, which has a series of longitudinal ribs (9) for facilitate the tightening and loosening of said valve, also having a small spigot (10) for the expulsion of air from inside the endoscope.
- connection valve (3) has an outer casing (3) of tubular configuration connected in a sealed manner and perpendicularly to its axis of revolution, which, in this embodiment of the invention, will be of a plastic material of high resistance to Ia Pressure.
- the device has an inner piston (4) which is also tubular and fits perfectly tightly in said housing, being able to move in a direction parallel to the axis (5) of revolution of said housing (3).
- a test line (7) consisting of a marking in a different color than the plunger (4) with a circular guideline and perpendicular to the axis (5).
- FIG. 4 shows the position of the piston (4) when it has reached the end of stroke of the piston (3) with respect to the housing (4) when exerting a certain pressure on it by the user.
