Definitions

  • the present invention discloses an equipment for winding medical tubing employing automated and sequentially-arranged workstations, which can be operated simultaneously.
  • Flexible plastic tubing is produced for a variety of sectors, ranging from engineering (automotive, aerospace), agriculture, horticulture and water management, plumbing, hydraulics, oil and gas, as well as the medical and healthcare.
  • the specifications of the tubing such as dimensions, material and its chemical and physical properties, are adapted to its specific use, whereby a coiled or wound assembly of the tubing generally eases the packaging, transport, use and manipulation of the tubing.
  • different types of coiling machines mostly employing motorised rotating reels, have been developed for industrial tubing and are available on the market today.
  • plastic tubing for fluid or gas transfer.
  • Such medical tubing must comply with international norms and display adequate quality requirements concerning its sterility, performance, ingredients, etc.
  • Document CN108313424 describes an automatic winding and bagging mechanism for a medical catheter.
  • the automatic winding and bagging mechanism comprises a rack, a catheter winding mechanism and a bagging grinding device, and the catheter winding mechanism and the bagging grinding device are sequentially arranged on the rack.
  • the throughput of this mechanism is limited.
  • Document US2018008798 discloses a device for holding coils of medical tubing to simplify packaging and handling thus making it easier for patient to manipulate each coil of tubing and reducing the probability of entanglement.
  • This solution is particularly suited to organise medical tubing conveying medical fluid in connection with dialysis machines, as it simplifies the handling of the tubing in a clinical or in a domestic setting.
  • this method does not provide a solution for winding large volumes of medical tubing at industrial scale.
  • One objective of the present invention is to provide an equipment for winding medical tubing which is adapted for industrial-scale manufacturing, thereby increasing efficiency of winding medical tubing.
  • Another objective is to propose an equipment for winding medical tubing which is capable of operating in a controlled environment, thereby reducing the risk of contamination.
  • those objectives are achieved by providing an equipment for winding medical tubing, employing a plurality distinct operational units performing automated tasks and which are capable of operating simultaneously comprising:
  • the equipment for winding medical tubing may furthermore comprise:
  • said one or more operational units can be arranged and combined with other operational units in sequentially arranged and simultaneously operating working stations, including
  • This equipment effectively solves the above-mentioned problems of the prior art with automated, sequentially-arranged units and sequentially arranged workstations which can operate simultaneously and are adapted for industrial-scale manufacturing to match a specific production line speed, thereby increasing efficiency and safety of winding and packaging medical tubing.
  • Each workstation can comprise a plurality of units in parallel and/or serial arrangement.
  • the number of units of each type might be increased to improve the throughput.
  • the number of workstations of each type might be increased to improve the throughput.
  • the number of units and/or workstations of different types might be different. For example, the number of slow units with a low throughput might be higher that the number of fast units with a higher throughput.
  • the equipment might comprise a plurality of bending units in parallel, and/or a plurality of winding units and/or winding stations in parallel.
  • Workstation of the same type may be mounted in parallel arrangement.
  • Workstation of different types may be mounted in serial arrangement.
  • the equipment may further comprise one or more said packaging units for packaging each tubing after its winding, said packaging units.
  • the arrangement of the units permits the equipment to operate efficiently and at a high and adjustable throughput rate due to the following favourable aspects:
  • the medical tubing is arranged in a "U"-shape with optimal dimensions for the winding process in the winding unit.
  • the ratio between the number of bending units, the number of loading units and the number of winding stations can be optimised to achieve efficient and smooth operations as well as a favourable throughput rate.
  • the distal end of the tubing is received below the plate of the winding station by rotatable jaws, which are connected to and rotating with the winding module, permitting winding of the medical tubing around the vertical axis of the winding module, thus facilitating a favourable compact arrangement of several winding units.
  • the rotatable jaws are operated by fixed jaw grippers which are actuated by an independent motor, thus permitting the rotatable jaws an unlimited range of freedom.
  • the rotatable jaws favourable perform a rotating movement along the vertical axis of the winding module together with the rotating winding core, which is actuated by a motor.
  • tube jaws favourably keep the tube positioned within the winding nest and below the level of the winding station plate.
  • the wound medical tubing is advantageously raised along the vertical axis to the level of the winding station plate in a controlled movement preventing the tubing from being compressed or damaged and presented to the grippers of the unloading unit which optionally transfer the medical tubing to the packaging unit.
  • the ratio between the number of winding stations, which may contain a plurality of winding units, and the number of the unloading units can be optimised to achieve efficient and coordinated operations as well as a favourable throughput rate.
  • a cover plate is advantageously positioned over it in an automated gliding movement, which prevents the unwinding of the wound medical tubing.
  • the present invention describes an equipment for automated winding of medical tubing employing sequentially arranged operational units and workstations, comprising a plurality of units.
  • a first workstation 1, called preparation station comprises at least one conveying unit 2 and at least one bending unit 3.
  • a second workstation 5, called winding station comprises at least one, but preferably a plurality of winding units 24.
  • One or more loading units 4 connect the operational processes of the preparation station 1 to the winding station 5.
  • One or more unloading units 6 connect the operational processes of the winding station 5 to a packaging unit 7.
  • the equipment of the present invention is configured to wind different type of medical tubing 10, such as but not limited to catheters, dialysis tubing, fluid management (drainage), respiratory equipment, biopharmaceutical equipment and others.

  • the unloading unit 6 might be configured to alternatingly remove medical tubing 10 ( Figure 2 ) from two winding stations 5 and transfer it to the packaging unit 7.
  • the above-mentioned numbers of workstations and different units are intended to be an example and can be varied according to specific needs.
  • the loading unit 4 and the unloading unit 6 might be equipped with sensors able to detect, if a receiving cavity, such as the winding nest 16 ( Figure 4 ) or the packaging container, is unloaded before the deposition of the medical tubing 10 ( Figure 4 ) in either the receiving cavity, thus enabling the equipment to operate in a highly coordinated and efficient manner.
  • a receiving cavity such as the winding nest 16 ( Figure 4 ) or the packaging container
  • the winding station 5 might be moved from proximity of the preparation station 1 to proximity of the packaging unit 7 during the winding process in order to minimise the transfer distances of the medical tubing 10 and to increase efficiency of the process.
