Abstract:
A medical coupling has male and female members (1, 2) which push fit together, and a screw cap (7) which secures the members against separation. To prevent unintentional release of the cap, locking means, such as a ratchet and pawl mechanism, are provided between the cap and female member. Au outer shell (25) can enclose the cap for providing an enclosure around the fluid connection to deter bacterial contamination. Alternatively a separate capsule can enclose the coupling for this purpose. The two members and cap are connectable by holding gripping portions which are located remotely from the parts forming the fluid connection to reduce risk of contamination. A valve system is associated with the female member for closing a flexible tube connected to this member and to displace liquid to fill the space left in this member when the male member is disconnected from it.
Abstract:
A securing device for medical and surgical applications has two parts which may be separate or integrally connected, one part comprising an eye (3) with a latching pawl (4) and the other part comprising a flexible strip (1) with ratchet teeth (2) so that the strip can be advanced through the eye to adjust the effective length of the flexible strip, but is locked against reverse movement. In one embodiment the parts are integral and a needle (7) is attached to the free end of the flexible strip, the device being a surgical suture. In another embodiment the parts are separate and are adapted to engage respective body parts of a patient which are to be held together by the device. A specific embodiment for a female incontinence sling procedure is described.
Abstract:
A coupling for a medical fluid delivery system for administering liquids to a patient includes male and female members, the female member (1) having an inwardly tapering socket (3) for receiving a complimentary tubular spigot (17) of the male member and having a liquid escape vent (9) for escape of liquid supplied from an incorrect or an incorrectly coupled male member. A collar (18) of the male member is threadedly engageable with a hub (2) of the female member for securing the members against disengagement, and the female member has a sleeve (5) with a pawl (6) which cooperates with ratchet teetch (20) on the collar to lock the collar against answering, the pawl being disengageable by squeezing the sleeve (5). The sleeve (5) has openings (8) to permit treatment of the hub and sleeve interior for destroying bacteria. The male member may be provided at the forward end of a syringe (34). The male and female members have in their gripping regions similar external profiles defined by radial wings (14, 25, 39) to provide a clear tactile indication that the correct parts are being used together.
Abstract:
A medical coupling for a cannula or the like includes a female member (1) with a body providing a hub (4) defining a socket (11), a valve section (5) with a valve actuator (15) slidable on the body, and a finger gripping section, and a male member (2) including a spigot (20) for engagement in the socket (11), a cap (21) with a screw thread for engagement with a flange (9) of the hub (4), an internally splined sleeve (24) and a finger gripping section (22). When the spigot (20) is inserted into the socket (11), the cap (21) is rotated onto the flange (10) to hold them against being pulled apart, and the valve actuator is displaced to open the valve and to bring a splined collar (19) into locking engagement with the sleeve (24). A separate casing (30) is provided to form sealed housing around the coupled parts of the male and female members between their griping sections (6, 22).

Abstract:
An intra-operative colon irrigation system comprises a drain tube (1) having a cylindrical body (10) with a forward end formed by a dome-shaped nozzle to prevent intussusception of the bowel into the drain tube. The forward end portion of the body is inserted into the bowel, and a rear end portion has a lug (26) with eyes (27) or securing "cable straps" (29) which are applied around the body and the collapsed bowel segment downstream of the bowel opening. To assist in breaking up solid faecal masses the drain tube includes an ultra-sonic device (16) or other means.
Abstract:
A biopsy needle for percutaneous and direct human tissue biopsy procedures comprises a cannula (1) and a stylet (2) respectively attached to sliders (8, 9) guided for movement in a barrel (7) of a handle (5) which has a pistol grip (6). The sliders have actuating flanges (10, 11) projecting from opposite sides of the barrel for advancing them in turn with the thumb of the hand holding the instrument.
Abstract:
A surgical device for use in hernia repair. It is made of a flat body of flexible material having a head portion (1) and tail portion (2). The head portion (1) is shaped to fit the space between the bladder, peritoneum and pre-peritoneal tissues during a hernia repair to prevent their prolapse into the operation field, and for hernia operations on the male, the tail portion is split (3 and 4) with a slot (5) formed on the line (6) of the split (5) to accommodate the male spermatic cord. The tail portion (2) also provides means to enable the device to be pulled from a small wound aperture after completion of hernia repair and substantial closure of the operation wound.
Abstract:
A device for use in surgical procedures formed of a concertina cartridge (1) of a resilient plastics material. The cartridge (1) has a nozzle (5), the throat of which is designed to receive by snap-click action, a projection (9) formed internally of the chamber (1), to hold the cartridge in a collapsed, but resiliently releasable, state as it is compressed to that state under concertina action. The device has applicability to surgical procedures such as blood collection, drug infusion, and balloon catheter inflation while eliminating the dangers of bacterial infection always present when performing such procedures using devices and systems of the prior art.
Abstract:
A method for hardening at a surface a component, the component being formed of a plastics material, comprises softening the component at a surface using carbon dioxide in a pressurised environment having a pressure of less than 74 bar, and incorporating into the component at the surface a material to harden the surface. There is also disclosed a device having one or more surfaces hardened by said method.
