Description
"WOUND IRRIGATION DEVICE"
The present invention pertains to improvements in the field of medical care. More particularly, the invention relates to an improved wound irrigation device.
Wounds require irrigation or washing with a fluid such as sterile water, a sterile saline solution or a Ringer lactate solution in order to dislodge any foreign particules contaminating the wound. Various wound irrigation systems are known. One such system comprises a syringe with a plunger movable therein and a one-way valve, a first flexible conduit connecting the valve to a bulk container of fluid for filling the syringe with fluid from the bulk container in response to an outward displacement of the plunger, and a second flexible conduit connected to the syringe for discharging the fluid therefrom onto the wound in response to an inward displacement of the plunger, the valve preventing the outflow of fluid back into the bulk container during the inward displacement of the plunger. Such a wound irrigation system is not only time-consuming to install, but also requires several pieces which add to the cost.
Another type of wound irrigation device is known, which consists of a syringe having a plunger movable therein and a single tube which serve for both filling the syringe with fluid and discharging the fluid therefrom onto a wound. Since use is made of a single tube having a diameter such as to provide a fluid pressure sufficient to adequately irrigate the wound, the filling operation is difficult and time-consuming.
It is therefor an object of the present invention to overcome the above drawbacks and to provide an improved wound irrigation device.
According to the invention, there is provided a device for irrigating a wound with a fluid, comprising a syringe having a hollow body defining a chamber adapted to contain the fluid, and a plunger movable within the body.

The device of the invention further includes valve means for selectively allowing the fluid to flow through the inlet tube and into the chamber during the outward displacement of the plunger, and for preventing the fluid from flowing from the chamber through the inlet tube during the inward displacement of the plunger.
In a preferred embodiment of the invention, the inlet and outlet tubes extend parallel to one another.
Preferably, the inlet and outlet tubes extend side-by side with the free end of the outlet tube extending beyond the free end of the inlet tube. Since in use the free end of the outlet tube is positioned in close proximity to the wound, such an embodiment prevents the free end of the inlet tube from being contaminated by the wound. It also facilitates the irrigation procedure since the free end of the inlet tube does not conceal the free end of the outlet tube from one's view so that the latter can be more easily positioned with respect to the wound.
According to another preferred embodiment, the valve means comprises a check valve adapted to selectively close the inlet tube in response to the inward displacement of the plunger, and to open the inlet

Referring first to Figs 1 and 2, there is illustrated a wound irrigation device which is generally designated by reference numeral 10 and comprises a syringe 12, a plunger 14, inlet and outlet tubes 16,18 and a check valve 20. The syringe 12 has a hollow body 22 defining a chamber 24 adapted to contain a fluid suitable for irrigating a wound (not shown), the body 22 being provided at one end with a finger flange 26. The plunger 14 which is movable within the body 22 includes a stem 28 provided at an inner end with a rubber head 30 and at an outer end with a thumb rest 32.
The inlet tube 16 is integral with the body 22 and is in fluid flow communication with the chamber 24 for filling the chamber with fluid in response to an outward displacement of the plunger 14 relative to the body 22. The outlet tube 18 is also integral with the body 22 and is in fluid flow communication with the chamber 24 for discharging the fluid from the chamber onto the wound in response to an inward displacement of the plunger 14 within the body 22. The inlet and outlet tubes 16,18 extend side-by-side and have respective free ends 34, 36 disposed adjacent one another. As shown, the free end 36 of the outlet tube 18 extends beyond the free end 34 of the inlet tube 16.
The check valve 20 is operative for selectively allowing the fluid to flow through the inlet tube 16 and into the chamber 24 in response the outward displacement of the plunger 14, and for preventing the fluid from flowing from the chamber 24 through the inlet tube 16 in response to the inward displacement of the plunger 14.

As shown, the free end 36 of the outlet tube 18 extends beyond the free end 34 of the inlet tube 16.
The check valve 20 is operative for selectively allowing the fluid to flow through the inlet tube 16 and into the chamber 24 in response the outward displacement of the plunger 14, and for preventing the fluid from flowing from the chamber 24 through the inlet tube 16 in response to the inward displacement of the plunger 14.
- 4 -As best shown in Fig. 2, the check valve 20 comprises a valve body 38 defining a valve chamber 40 in fluid flow communication with the fluid passageway 42 of inlet tube 16, and a cylindrical valve member 44 movable in the valve chamber 40 between close and open positions to selectively close and open the fluid passageway 42.
Planar elongated guide members 46 each provided with an abutment 48 are arranged in the valve chamber 40 so that the valve member 44 is movable along limited guided path, the abutments 48 serving to arrest the valve member 44 in the open position.
As also shown in Fig. 2, the outlet tube 18 has a fluid passageway 50 with a first diameter and the free end 36 of the outlet tube 18 defines a fluid discharge orifice 52 having a second diameter smaller than the first diameter, whereby to increase the pressure of the fluid discharged from the orifice 52.
In operation, the inlet and outlet tubes 16,18 inserted are into a bulk container (not shown) of fluid so that the free ends 34, 36 are immersed into the fluid, the plunger 14 is displaced outwardly to draw fluid from the bulk container through the inlet tube 16 and into the chamber 24 of the syringe 12, with the valve member 44 moving to the open position, the tubes 16,18 are removed from the bulk container and directed towards a wound to be irrigated, and the plunger 14 is displaced inwardly within the syringe body 22 to cause the fluid to flow from the chamber 24 through the outlet tube 18 so as to be discharged under pressure from the orifice 52 onto the wound. As the plunger 14 is displaced inwardly within the syringe body 22, the valve member 44 moves to the close position, thereby preventing the fluid from flowing from the chamber 24 through the inlet tube 16.

Since in use the free end 36 of the outlet tube 18 is positioned in close proximity to the wound, and in order to present fluid splashes contaminated by the wound form reaching the user during the inward displacement of the plunger 14, a parabolic fluid splash arresting member 56 is mounted on the inlet and outlet tubes 16,18. The member 56 has an opening (not shown) which is defined therethrough and off-centered relative to the central axis (not shown) of the member 56, the inlet and outlet tubes 16,18 extending through the opening. The central axis of the member 56 is inclined at an angle of about 30° relative to the longitudinal axes of the inlet and outlet tubes 16,18 to provide a better protection. In addition, the member 56 is slidably mounted on the inlet and outlet tubes 16,18 for adjustable positioning therealong.
