Abstract

A wrap replacing apparatus according to the embodiments includes: an insertion port into which a medical device wrapped in a first bag is inserted; a peeler configured to peel off the first bag from the medical device inserted into the insertion port; a wrapper configured to wrap in a second bag the medical device from which the first bag is peeled off; and a take-out port from which the medical device wrapped in the second bag is taken out.

First claim

The invention claimed is:

1. A wrap replacing apparatus comprising:
an insertion port into which a medical device wrapped in a first bag is inserted, the medical device having been used in a state of being wrapped by the first bag;
a peeler configured to peel off the first bag from the medical device inserted into the insertion port;
a wrapper configured to wrap in a new second bag, the medical device after the first bag is peeled off; and
a take-out port from which the medical device wrapped in the second bag is taken out, wherein
the peeler includes a conveyer configured to convey the medical device wrapped in the first bag,
the wrap replacing apparatus further includes an inciser configured to incise the first bag wrapping the medical device conveyed by the conveyer,
the peeler peels off the first bag incised with the inciser from the medical device, and
the conveyer and the peeler correspond to a pair of rollers that sandwiches and conveys the medical device wrapped in the first bag and winds up the first bag peeled off from the medical device.

2. The wrap replacing apparatus according to claim 1 , wherein the take-out port is provided at a position different from the insertion port.

3. The wrap replacing apparatus according to claim 1 , wherein the inciser is provided at a position facing a side surface of the medical device conveyed by the conveyer.

4. The wrap replacing apparatus according to claim 1 , wherein the inciser incises the first bag wrapping the medical device, along a groove provided in the medical device.

5. The wrap replacing apparatus according to claim 4 , wherein the inciser includes a side surface inciser that is fixed to an upper side of a central axis of each of the rollers and incises, by the medical device being conveyed by the rollers in a state in which the inciser is disposed inside the groove provided in a side surface of the medical device, a portion that is included in the first bag and is attached to a side surface of the medical device.

6. The wrap replacing apparatus according to claim 4 , wherein the inciser includes a bottom surface inciser configured to incise a portion that is included in the first bag and is attached to a bottom surface of the medical device, by moving in a width direction of the medical device, inside a groove provided in the bottom surface of the medical device.

7. The wrap replacing apparatus according to claim 4 , wherein the inciser includes an upper surface inciser configured to incise a portion that is included in the first bag and is attached to an upper surface of the medical device, by moving in a width direction of the medical device.

8. The wrap replacing apparatus according to claim 1 ,
wherein an outer peripheral surface of each of the rollers has adhesiveness, and
the rollers peel off the first bag from the medical device and wind up the peeled off first bag.

9. The wrap replacing apparatus according to claim 1 ,
wherein each of the rollers includes a protrusion,
the first bag includes an engager configured to engage with the protrusion, and
by the rollers rotating in a state in which the engager is engaged with the protrusion, the medical device is conveyed while the first bag peeled off from the medical device is wound around each of the rollers.

10. The wrap replacing apparatus according to claim 1 ,
wherein the peeler further includes:
a rotation pin that is provided below each of the rollers and is configured to hook to peel off, by rotating, the first bag attached to the medical device; and
a collector configured to collect the first bag hooked on the rotation pin.

11. The wrap replacing apparatus according to claim 1 ,
wherein the first bag includes a fragile portion smaller in strength than a remaining portion, and
the fragile portion is provided to a portion attached to a side surface of the medical device and a portion attached to a bottom surface of the medical device.

12. The wrap replacing apparatus according to claim 1 ,
wherein the wrapper is configured to:
fix the second bag to a lower side of the peeler; and
seal an opening of the second bag into which the medical device is inserted.

13. The wrap replacing apparatus according to claim 1 ,
wherein the second bag is produced using a sheet that shrinks from heat applied thereto, and
the wrapper produces the second bag by shrinking the sheet by applying heat to the sheet in a state in which the medical device is wrapped in the sheet.

14. The wrap replacing apparatus according to claim 1 , wherein the medical device is an X-ray detector or an ultrasound probe.
