The light emitting device 7 may comprise a light bulb or LED and may be mounted in a buckle housing 3. The light is preferably mounted externally on the buckle housing 3 and the remainder of the light generation arrangement may be disposed inside the housing 3. The light generation arrangement may comprise a power source and circuitry to enable activation of the light source in response to the activation of a switch 8. The buckle connection is preferably a quick release mechanism with mating connectors 4, 6.

Description

Tourniquet Device The present invention relates to a tourniquet device.

Tourniquet devices are known and are sometimes referred to as ligature devices or by other names. Their common feature is a flexible band that can be tightened around a limb or other body part in order to restrict blood flow for medical reasons. Such devices are standard, frequently used medical devices and are routinely carried by doctors, paramedics and other medical personnel. Such devices may also typically be found in first aid kits.

Exemplary prior art tourniquet devices are disclosed in for example US2004/0 127938 and US62 17601. Such devices include an elasticated band to which is secured a buckle housing intermediate the ends of the band and a terminal connector at one end of the flexible elasticated band. The portion of the band extending between the strap mounted buckle housing and the terminal connector cn be looped arou-1d the body df of the patient (for example the patients limb) and the terminal connector can be mated with the buckle housing (typically in snap fit connection style). The free end of the strap can then be pulled through the strap mounted buckle housing in order to tighten the band around the body part of the patient. The buckle connection is typically quick release to facilitate easy removal of the device from the body part of the patient at the appropriate time following completion of the medical intervention.

The terms tourniquet and ligature may be used interchangeably and relate to a general class of device including a flexible tightenable band for medical procedures.

According to the present invention, there is provided a tourniquet or ligature type device comprising a flexible band and carrying a light emitting device.

In one embodiment it is preferred that the light emitting device is mounted on-board a rigid element secured on the flexible strap or band.

In certain embodiments it is desirable that the light emitting device is mounted in a housing secured on the flexible strap or band. Electrical components enabling operation of the light may be provided in the housing, which may beneficially mount a switch actuator for operation of the light emitting device Beneficially, the tourniquet or ligature device includes first and second connector elements secured to spaced apart portions of the strap band, the connector elements being arranged to engage with one another. The connector elements may comprise plastics snap-fit quick-release connectors, as are well known in the art. Beneficially, the light emitting device is mounted on-board one of the connector elements.

In one embodiment the respective connector element may have a first side provided with a connector fonnation for connection with the other connector element, the light emitting device being secured at the side of the connector opposed to the first side.

It is preferred that the light eniitter deviec may be usable whilst mounted to the tourniquet device In certain embodiments it may be desirable for the light emitter device to be de-mountable from the tourniquet device to be usable whilst de-mounted from the tourniquet device The invention will now be described, by way of example only and with reference to the accompanying drawing, which is a schematic perspective representation of a tourniquet device in accordance with the invention.

Referring to the drawing there is shown a tourniquet device (1) comprising an elasticated strap band (2) to which is secured a plastics moulded buckle housing (3) which is positioned intermediately between the ends of the strap band. A terminal connector (4) is provided at one end of the flexible elasticated strap band (2). The buckle housing (3) is movable, with effort along the strap band but securely attached thereto, being clamped to the strap band in the manner of a webbing belt fixing that is well known in this and other areas of technology. The portion (2a) of the strap band (2) extending between the strap band mounted buckle housing (3) and the terminal connector (4) can be looped around the body part of the patient (for example the patients limb) and the terminal connector (4) can be mated with the buckle housing (3) in a snap fit connection (as indicated by arrow A in the figure). The free end (5) of the strap band can then be pulled through the strap mounted buckle housing (3) in order to tighten the strap band (2) around the body part of the patient.

The buckle connection is typically quick release to facilitate easy removal of the device from the body part of the patient at the appropriate time following completion of the medical intervention. In the embodiment shown the connection between the strap mounted buckle housing (3) and the terminal connector (4) is male/female and the male connector comprises the terminal connector(4) and the female connector is in the form of a receiving socket (6) integrally moulded with the strap mounted buckle housing (3). It should be appreciated that other arrangements can be envisaged, and particularly the positions of the male and female connector elements could be reversed.

In accordance with the present invention the device carries a light generation arrangement including a light (7) which may be a light bulb, LED or other device which is conveniently mounted in the buckle housing (3). The light (7) is mounted externally on the housing on the opposite side of the housing (3) to the buckle connector formation (in this embodiment the female socket 6). This is believed to provide the most advantageous arrangement for use. A light switch (8) is also mounted externally on the housing (to one side of the housing) for operation of the light (7).

The remainder of the light generation arrangement is disposed internally of the buckle housing (3) and comprises a power source (such as one or more batteries) and the required circuitry and connections to enable operation of the light bulb or LED in response to activation of the switch. In one embodiment the device could include a solar cell/photodiode device and storage means enabling the use of batteries to be dispensed with or a solar cell/photodiode device to charge the battery. The buckle housing may comprise an openable casing permitting the battery and/or electrical light bulb, LED or the like to be replaced.

In use the tourniquet can be used in the conventional manner despite the presence of the light emitting device on-board the tourniquet. In circumstances in which the practitioner requires a light for illumination purposes, then provided the practitioner is in possession of the tourniquet device, an illumination device is conveniently at hand. Medical practitioners can often benefit from a torch or light being to hand, for example in order to conduct neurological examinations, ophthalmic examination, for ear nose and throat investigations for example. Frequently such a torch or light may not be being carried, but a tourniquet device may be.

The light emitter device may be usable whilst mounted to the tourniquet device.

Alternatively, or additionally the light emitting device could be demountable from the tourniquet device for use. This could be achieved for example by having a separable housing for the light emitting device that is connected in a demountable manner to the buckle connector (3) or other structure of the tourniquet device.

The device has been described with the light emitting device mounted on-board the tourniquet device by means of mounting with the buckle housing (3). In other embodiments it is envisaged that the light emitting device could be mounted on-board the tourniquet device by other means for example by being mounted to the strap band 2 (for example at the free end 5 of the strap band 2), or mounted to the terminal buckle connector (4). Furthermore, the light emitting device could be demountable from the tourniquet device for use.

The embodiments described are intended to illustrate aspects of the invention rather than limit the scope of the invention, and those skilled in the art will be capable of designing alternative embodiments without departing from the scope of the invention as defined by the appended claims. -5-.
