Description

(54) IMPROVEMENTS IN OR RELATING TO MEDICAL INSTRUMENTS (71) We, BARFIELD TRUST CO.
LIMITED, a Guernsey Company, of P.O.
Box 71, 7 New Street, St Peter Port, Guernsey, Channel Islands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: According to one aspect of the present invention, there is provided a medical syringe for body cavities, said syringe being of pistol-like shape with a barrel and a hand grip, and comprising a duct extending to a forward end region of the syringe for conducting water to said forward end region whence the water exits as a syringing jet, optical inspection means extending to said forward end region whereby a user can inspect a cavity being syringed, and light-transmitting means extending to said forward end region for transmitting light from a light source to said cavity for illuminating said cavity, said light-transmitting means comprising light-transmitting fibre.
In order that the invention may be clearly understood and readily carried into effect, reference will now be made, by way of example, to the accompanying drawing, in which: Figure 1 shows a diagrammatic side elevation of an ear syringe connected to water and electricity supply apparatus, and Figure 2 shows a diagrammatic perspective view of a forward end portion of the syringe.
Referring to the drawing, the syringe includes a water duct 1 extending from a plug-in connection 20, for a flexible water supply pipe 21 connected to a water supply device 22, to the forward end of the syringe for conducting water to the forward end, whence the water exits as a syringing jet.
The device 22 is contained in a box separate from the syringe and includes a water reservoir tank 24 and a pump 25 and a heater 26 for pumping and heating the water. The syringe also includes an optical inspection device 2 with an optical axis A and extending from an eyepiece 4 to the forward end of the syringe and including a magnifying lens system including lenses 12, whereby the user can view the region of the ear being syringed. The syringe further includes light-transmitting fibre 3 extending to the forward end of the syringe from a light source 5 in the form of an electric bulb. The bulb 5 is in circuit with a low-voltage output of a mains transformer 6 via a plug-in connection 27 and a flexible electrical cable 28, although it could instead be in circuit with electrical supply batteries (not shown).
The syringe is of a pistol-like shape, with a barrel 7 containing the optical inspection device 2, the fibre 3 and the bulb 5; a hand grip 8 housing the batteries when these are provided, and also an electrical on / off switch 9 controlling the circuit of the pump 25; and a finger-operated, spring-return button 11 which actuates the switch 9. A hand-operated, water flow control valve 10 is interposed between the pump 25 and the pipe 21. The valve 10 is not simply an on/off valve, but also controls the rate of flow of water through the duct 1. At their forward ends, the device 2 and the fibre 3 are covered by a transparent glass seal 13, which is perforated at 14 in line with the duct 1 to allow passage of the water jet.
At these forward ends, the fibre 3 is distributed around the duct 1 and the device 2.
WHAT I CLAIM IS: 1. A medical syringe for body cavities, said syringe being of pistol-like shape with a barrel and a hand grip, and comprising a duct extending to a forward end region of the syringe for conducting water to said forward end region whence the water exits as a syringing jet, optical inspection means extending to said forward end region whereby a user can inspect a cavity being syringed, and light-transmitting means extending to said forward end region for transmitting light from a light source to said cavity for illuminating said cavity, said light-transmitting means comprising light-transmitting fibre.
2. A syringe as claimed in claim 1, wherein said light source comprises an

4. A syringe as claimed in claim 2 or 3, wherein said optical inspection means includes an eyepiece at the rearward end of said barrel.
5. A syringe as claimed in any preceding claim, wherein, at said forward end region, said duct is situated above said optical inspection means.
6. A syringe as claimed in any preceding claim, and further comprising, at the forward end of said syringe, a transparent sealing member covering the forward end of said optical inspection means and the forward end of said light-transmitting means but not the forward end of said duct
7. A syringe as claimed in any preceding claim, wherein, at said forward end region, said fibre is distributed around said optical inspection means and said duct.
8. In combination, a pump, a syringe as claimed in any preceding claim, and a flexible, water-conducting pipe connecting said syringe to said pump,
