Description

Medical Tourniquet Device The present invention relates to a medical 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 US2004/0127938 and US6217601. 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 can be looped around the body part 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 device comprising a flexible strap or band and carrying a self contained torch light emitter unit having a housing for mounting on the strap or band the light emitter unit provided with an on-board electrical power device, a light emitter arranged to generate light in the visible spectrum to be directed outwardly from the housing, and a switch for controlling operation of the light emitter, enabling the light emitter unit to be used as a general purpose torch or flashlight.
In one embodiment it is preferred that the light emitter unit is de-mountable from the tourniquet device to be usable whilst de-mounted from the tourniquet device. This enables the light emitter unit to be used as a flashlight or torch separated from the tourniquet or ligature, in addition to being usable whilst in a mounted condition.
In an embodiment where the light emitter unit is demountable, it is preferred that a receiving structure or platform for the light emitter unit is positioned on the strap or band and the light emitter unit is mountable with, and demountable from, the receiving structure or platform. The receiving structure or platform is typically slidable on the band or strap, in order to change the position of the receiving structure on the band or strap. In an embodiment where the light emitter unit is demountable, it is preferred that the light emitter unit is slide or snap-fit engageable with the receiving structure.
It is preferred that the tourniquet or ligature device includes first and second connector elements secured to spaced portions of the strap band, the connector elements being arranged to engage with one another; wherein the light emitter unit is separate from the connector elements.
The light emitter unit is preferably usable whilst mounted to the tourniquet device. In one embodiment, the on-board electrical power device comprises a battery.
In an alternative embodiment, the on-board power device comprises a photo-voltaic device. It is preferred that the light emitted by the light emitter device is white light comprising multiple wavelengths in the visible range of the spectrum. According to an alternative view, the invention provides a tourniquet or ligature device having a mounted thereon a general purpose flashlight or torch. The invention will now be described, by way of example only and with reference to the accompanying drawings, in which:
Figure 1 is a schematic perspective representation of a tourniquet device in accordance with the invention.
Figure 2 is a schematic side view of an alternative embodiment of a device in accordance with the invention;
Figure 3 is a perspective view of the device of figure 2.
Referring to the drawings, and initially to figure 1, 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 buckle housing (3) comprises a torchlight emitter unit (3) arrangement including a light (7) which may be a light bulb, LED or other device which is conveniently mounted in the housing (3). The light emitted is multiple wavelength and in the visible range of the spectrum, preferably being white light. The bulb or LED (7) is mounted externally on the housing on the opposite side of the torchlight emitter unit 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 (3) (to one side of the housing) for operation of the light (7).
The remainder of the light generation arrangement is disposed internally of the 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. The light emitter unit in housing (3) comprises a self contained unit and may be usable whilst mounted to the tourniquet device. Alternatively, or additionally the light emitting unit 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 demountable unit may be preferred for sterilization or other purposes. The device has been described in this embodiment 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 onboard 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.
In the embodiment of Figures 2 and 3, the light emitter unit (103) is mounted to the strap band (102) separately from the tourniquet buckle housing (113). The light emitter unit (103) is mounted to de-mountably engage with a receiving platform (114). The receiving platform (114) has a slot or channel enabling the receiving platform to be slidably retained on the strap band (102). Securing projections (11 , 120) project outwardly from the surface of the platform (114) enabling de-mountable 'snap fit' engagement with complementary formations (121) provided on the underside of the light emitter unit (103).
The light (107) may be a light bulb, LED or other device which is conveniently mounted in the unit (103). The light emitted is multiple wavelength and in the visible range of the spectrum, preferably being white light. The bulb or LED (107) is mounted to direct light externally from the unit. The light switch (108) is also mounted externally on the unit (103) (on top of the housing) for operation of the light (107).
The strap and buckle connectors may be similar to those of the first embodiment, the male terminal connector on the strap (102) connecting with a connector socket provided in the buckle housing (113).
The remainder of the light generation arrangement is disposed internally of the unit (103) 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. 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, a general purpose torchlight 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. Devices having light emitters mounted to medical band or strap devices are known, from for example US2005/0215875 and WO2009/049433. These are specialised devices for directing specific wavelength radiation for visualization of subcutaneous structures such as veins.
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.
