Abstract

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices, systems and methods for air/water and flushing valves. For example, an endoscopic valve of the present disclosure may include a valve stem with contiguous first and second channels and with first and second ports formed within a sidewall of the valve stem. A series of seals may be disposed around an outer surface of the valve stem proximal and distal to the first and second ports. A gating member may be slidably disposed within the proximal channel and a valve insert may be disposed between the proximal and distal channels.

First claim

What is claimed is:

1. An endoscopic valve, comprising:
a valve stem, comprising:
a proximal channel with a proximal opening and a distal channel with a distal opening, the proximal and distal channels defining a contiguous channel, a first port formed within a sidewall of the valve stem and in fluid communication with the proximal channel, and
a second port formed within the sidewall of the valve stem and in fluid communication with the proximal channel;
a first seal disposed around an outer surface of the valve stem and distal to the first port;
a second seal disposed around the outer surface of the valve stem and distal to the second port;
a third seal disposed around the outer surface of the valve stem and distal to the second seal;
a gating member slidably disposed within the proximal channel, wherein the gating member is configured to move between a first position in sealing contact with the first port and a second position in sealing contact with the second port, and wherein a lumen extends through the gating member; and
a valve insert disposed between the proximal and distal channels.

2. An endoscopic system, comprising:
the endoscopic valve of claim 1 ; and
a modular attachment insertable into the proximal channel of the valve stem to move the gating member from the first position to the second position and to move the valve insert from a first position to a second position.

3. An endoscopic system, comprising:
a housing of an endoscope, comprising:
a housing of an endoscope, the housing comprising:
an air outlet port formed within a sidewall of the housing,
an air inlet port formed within the sidewall of the housing and distal to the air outlet port,
a water outlet port formed within the sidewall of the housing and distal to the air inlet port, and
a water inlet port formed within the sidewall of the housing and distal to the water outlet port; and

the endoscopic valve of claim 1 , wherein the valve stem is movable between a first configuration and a second configuration within the housing of the endoscope.

4. The endoscopic system of claim 3 , wherein in the first configuration, air is flowable from a processing system through the air inlet port and into the valve stem, and in the second configuration, water is flowable from the processing system through the water inlet port, into the valve stem and through the water outlet port.

5. The endoscopic system of claim 4 , wherein the air is flowable through a proximal opening of the valve stem into the atmosphere.

6. The endoscopic system of claim 4 , wherein the air is flowable through the air outlet port when a proximal opening of the valve stem is blocked.

7. The endoscopic system of claim 3 , wherein the valve stem is movable between the first configuration, the second configuration and a third configuration within the housing of the endoscope.

8. The endoscopic system of claim 7 , wherein in the first configuration, air is flowable from a processing system through the air inlet port and into the valve stem.

9. The endoscopic system of claim 8 , wherein the air is flowable through a proximal opening of the valve stem and into the atmosphere.

10. The endoscopic system of claim 8 , wherein the air is flowable through the air outlet port when a proximal opening of the valve stem is blocked.

11. The endoscopic system of claim 7 , wherein in the second configuration, water is flowable from a processing system through the water inlet port, into the valve stem and through the water outlet port.

12. The endoscopic system of claim 7 , wherein in the third configuration, water is flowable from a processing system through the water inlet port, into the valve stem and through the air outlet port, and water is flowable from the processing system through the water inlet port, into the valve stem and through the water outlet port.

13. An endoscopic system, comprising:
a housing disposable within an endoscope handle;
a length of tubing extending from the endoscope handle to a processing system;
an insertion tube extending from the endoscope handle;
an endoscopic valve movable between a first configuration and a second configuration within the housing, wherein the endoscopic valve comprises a valve stem with a proximal channel and a distal channel;
a gating member slidably disposed within the proximal channel;
a first air channel and a first water channel extending from the processing system to the housing through the length of tubing; and
a second air channel and a second water channel extending from the housing through the insertion tube.

14. The endoscopic system of claim 13 , wherein in both the first and second configurations, air is flowable from the processing system through the first air channel and into the valve stem, and
water is flowable from the processing system through the first water channel, into the valve stem and through the second water channel.

15. The endoscopic system of claim 14 , wherein the air is flowable through a proximal opening of the endoscopic valve into the atmosphere.

16. The endoscopic system of claim 13 , wherein the endoscopic valve is movable between the first configuration, the second configuration and a third configuration within the housing, wherein in the third configuration, water is flowable from the processing system through the first water channel, into the valve stem and through the second air channel, and water is flowable from the processing system through the first water channel, into the valve stem and through the second water channel.
