Abstract
ABSTRACT OF THE DISCLOSURE A wound irrigating device includes a cover and a rim, the rim being of an adhesive which will adhere to moist body surfaces, the cover and the rim, when in use, defining a closed chamber located over the wound. The device has an entry and an exit port fox supply and removal of an irrigating fluid to the wound. The rim itself is, or it may carry a plastics adhesive material which may include a blend of a water-soluble or water-swellable hydro-colloid and a water-insoluble, viscous, elastic binder.
Description
~Z7~
WID
This invention relates to a wound irrigating device.
There have been numerous prior proposals for wound irrigating or drainage devices. For example, in sritish Patent Specification Number 641 061, there is disclosed a transparent convex shield which covers the wound and has inlet and discharge connections for a liquid used to wash or medicate the wound. A gasket of soft rubber is inter-posed between the skin and the shield. In British Patent Specification Number 1 150 294, there is disclosed a sel-ectively permeable membrane which is laid over the wound and may have liquid inlet and outlet connections. British Patent Specification Number 1 210 746 discloses an appliance for treating sagging breasts. It has a cup of glass or plastics having a soft rubber marginal sleevel and a tube ~or entry and exit of water. British Patent Specification Number 1 395 799 discloses a surgical evacuator having a rigid cup and a diaphragm therein for producing a suction.
The cup has a marginal flange which engages the body of the patient. In United States Patent Number 3 042 041, t~ere is disclosed a cup which is placed over a wound, in combination with a drainage tube which in use extends into the wound. The interior of the cup is maintained under suction. A rim is provided to engage the skin of the user. United States Patent Numbe~ 3 954 105 discloses a drainage system in which a thin pliable sheet of plastics material is adhesively secured to the patient around the wound. A blanket of gelatinous material containing karaya gu~ is also provided. In United States Patent Number 3 568 675 r a surgical d~essing is illustrated which has a moulded ~b WID
plastics cover dome. This is secured to the patient with collodion, or equivalent compounds. An exit tube for drainage is provided. United States Patent Number 2 280 915 discloses a device for irrigating wounds having a special pad construction at its base, and entry and exit orifices for fluid. A suction may be applied to the interior and this enhances the security of attachment to the patient.
Other prior proposals have been made, inter alia, in British Patent Specification Numbers 992424, 1214707, 1384537, and 1457164, and in United States Patent Numbers

3 367 332.
None of these prior proposals are totally satisfac-tory from the points of view of security of attachment of the device to the patient, and ease and comfort of the patient while the device is being worn. In addition, the use of many of them makes heavy demands on skilled nursing ~imer According to the inVention, a wound irrigating device includes a cover and a rim, the rim being of an adhesive Wh~ch will adhere to moist body surfaces, the cover and the rim in use defining a closed chamber located over the wound and also defining an entry and an exit port for supply and removal of an irrigating fluid, in which the rim is or carries a plastics adhesive material comprising a blend of a water-soluble or water-swellable hydro-colloid and a water-insoluble, viscous, elastic binder.
WID
The invention also provides a method of making a wound irrigating device which involves bonding a cover to such a rim, and providing in the rim or in the cover an entry and an exit port for a fluid used as a wound irrigating fluid.
The cover may be of a synthetic plastics material.
It may be transparent or it may have a transparent panel therein, so that the wound can be inspected without re-moving the device from the patient. The cover may be flexible or rigid. The adhesive material used may be as described in British Patent Specification Number 1 088 992. The adhesive may be secured directly to the cover rim or there may be a ring interposed therebetween for ease of manufacture. A drain bag may be secured to the outlet port, and one or more valves may be provided to allow control of the wound irrigation process.
In this Specification, the word `'wound" is used to mean.any break in the skin of a patient, and specifically includes both wounds caused by accidents or the like and wounds made in the course of surgery.
The invention will be better understood from the following particular and non-limiting description of an example thereof given with reference to the accompanying drawings in which:-Figure 1 is a plan view of one form of wound irri-gating device;
and Figures 2 and 3 are cross-sections on the lines II-II and III-III respectively of Figure 1.
The device illustrated in Figure 1 includes a flexi-ble cover 10 which may be of a synthetic plastics material such as "PERSPEX". I'he cover is slightly domed to enclose a space beneath it and above the wound 12. The cover has a rim 14 to which is at-tached a layer 16 of a plastics adhe-sive material comprising a blend of a water-soluble or water swellable hydro-colloid and a water-insoluble, viscous, el-astic binder. This is laid direc-tly on the skin 18 of the patient. The adhesive rim material is more fully described in British Patent No. 1,088,092 granted to E.R. Squibb &
Sons, Inc. As described in that patent, the adhesive rim material comprises a blend of a water-soluble or water-swellable hydrocolloid and a water-insoluble, viscous elas-tic binder. Such adhesive material may comprise, as the water soluble or swellable hydrocolloid, polyvinyl alcohol, powdered pectin, gelatin, carboxymethylcellulose, high mole-cular weight polyethylene glycol, i.e~, the solid type of material sold under the trademark "Carbowax" or carboxypoly-methylene or a mixture of two or more of these substances.
~0 The viscous elastic binder may be a natural or synthetic ~um-like substance such as natural rubber, silicone rubber, acrylonitrile rubber, polyurethane rubber, polyisobutylene, and sucrose acetate isobutylate or a mixture of such sub-stances. The cover and the rim define an entry port 20 and an exit port 22 for irrigating fluid. A conventional D.I.
infusion set 24 is illustrated as connected to the entry port 20. It may include means such as a bung 26 whereby a gas such as hydrogen peroxide may be flushed through the device.
An outlet pipe 28 is connected to the exit port 22 and leadsr in use, to a closed drainage system. It will be appreciated that a control valve, either manually or remote-* Trade Mark ~7~
ly operable, can be associated with either or both of theentry or exit ports.
A wound irrigating device such as is par-ticularly dis-closed and illustrated herein has the following advantages:-1. It provides a system for localized irrigation of in-fected wounds with antiseptics or hydrogen peroxide thus removing infected material and promoting the healing process.
- 4a -~ 4 ~ WXD
2. It reduces the exposure of infected wounds to the atmosphere by eliminating the handling of soggy, wet dressings. Thus, it provides localized barrier nursing around the wound itself.
3. It prevents maceration of surrounding skin by wet dressings.
None of these prior proposals are totally satisfac-tory from the points of view of security of attachment of the device to the patient, and ease and comfort of the patient while the device is being worn.
