Abstract

1329291 Peristaltic pumps AIR-SHIELDS Inc 11 Aug 1970 [15 Aug 1969] 38723/70 Heading F1F [Also in Division A5] Wound drainage equipment comprises a peristaltic pump formed by a rotary pump element 38 and a guide element 55 which operate on the resilient walls of a drainage tube 70, 70a to propel liquid drained from a wound into a collection bag(74) which is sealed to the drainage tube. The equipment includes means for regulating the vacuum in the drainage tube upstream of the pump, the means comprising a branch tube 79 from the drainage tube 70a communicating with a valve assembly 99. When the pressure in the drainage tube falls below a level determined by the screw adjuster 101, 102 the valve 99 opens to vent the tube to the atmosphere via a filter 98. The pump element 38 comprises a central disc (41) on the circumference of which are rotatable rollers 43, the disc being sandwiched between plates (44, 45) holding the rollers in position. The equipment may also be fitted with means for periodically venting the drainage tube so that gravity will draw the liquid in the tube back into the wound, so back-flushing the tube and removing any particles clogging the end of the tube. The venting means may be a solenoid valve 106 which is activated by a micro-switch, said micro-switch being periodically closed by the cam of a timing motor. The resilient tube (70) on which the pump operates may be heat sealed to the collection bag (74) at one end and to a T piece 71 at the other, the T piece in turn being heat sealed to a drainage tube 70a and a vent tube 79, forming a disposable unit. This disposable unit is loaded into the pump by raising the pump cover 30 which causes the guide element 55 to move away from the pump element 38, giving sufficient clearance between the pump element and guide element to insert the resilient portion of the tube 70. The lid 30 is then closed, causing the guide element 55 to move back towards the pump element so locking the tube in the working position shown in Fig. 4. The collection bag may be hung by loops formed thereon from the frame which supports the pump. An actuating member fitted to the guide element 55 operates on the micro-switch 113 to interrupt the electrical supply to the pump motor should the cover be raised whilst the pump is running.
