Furthermore, as illustrated in
As illustrated in
Furthermore, as illustrated in
As illustrated in
The first fluid passage portion 3 and the second fluid passage portion 4 are provided to allow the fluid R supplied from the fluid supply apparatus 100 via the port 45 to pass through, and each are formed of, for example, a tubular member.
Furthermore, the second fluid passage portion 4 has a diameter larger than a diameter of the first fluid passage portion 3, and the first fluid passage portion 3 is arranged inside the second fluid passage portion 4 along the second fluid passage portion 4. In other words, the first fluid passage portion 3 and the second fluid passage portion 4 jointly form a known coaxial tube.
The fluid supply apparatus 100 includes the first conduit 43 that comes into communication with the first fluid passage portion 3 when the fluid supply apparatus connection portion 5 is connected to the port 45, the first conduit 43 supplying the fluid R to the first fluid passage portion 3 via the introduction port 3i, and the second conduit 44 that comes into communication with the second fluid passage portion 4 when the fluid supply apparatus connection portion 5 is connected to the port 45, the second conduit 44 supplying the fluid R to the second fluid passage portion 4 via the introduction port 4i.
Furthermore, the second conduit 44 has a diameter larger than a diameter of the first conduit 43 in a region upstream of a first flow control section 63 and a second flow control section 64, which will be described later, and the first conduit 43 is located inside the second conduit 44 in the region upstream of the first flow control section 63 and the second flow control section 64.
As illustrated in, for example,
The first flow control section 63 is provided at a position part way through the first conduit 43. Also, the second flow control section 64 is provided at a position part way through the second conduit 44. The first flow control section 63 and the second flow control section 64 each include, for example, an openable/closable solenoid valve. Furthermore, operation to open/close the first flow control section 63 and the second flow control section 64 is controlled by a control section 40 provided in the fluid supply apparatus 100.
Furthermore, the first conduit 43 is in communication with the second conduit 44 in a region downstream of the first flow control section 63 and the second flow control section 64, and a pump 41 for fluid supply is provided in the region downstream of the communication portion. Driving of the pump 41 is controlled by the control section 40. Also, the pump 41 may be a self-suction pump that can deliver a gas.
Although the configuration downstream of the pump 41 is omitted for simplicity of illustration in
As a result, when the pump 41 is driven, a fluid R such as a cleaning solution, a disinfectant solution, rinse water or a gas is supplied selectively or simultaneously to the first fluid passage portion 3 and the second fluid passage portion 4 via the first conduit 43 and the second conduit 44 according to whether the first flow control section 63 and the second flow control section 64 are in an on (opened) or an off (closed) state.
The control section 40 performs control to open/close the first flow control section 63 and the second flow control section 64, and thereby performs control to supply the fluid R to at least one of the first conduit 43 and the second conduit 44. Furthermore, the control section 40 has a function for controlling an amount of supply of the fluid R flowing in the first conduit 43 and an amount of supply of the fluid R flowing in the second conduit 44 by means of controlling the time during which the first flow control section 63 and the second flow control section 64 are opened and the time during which the pump 41 is driven.
Hereinafter, a method for controlling the first flow control section 63 and the second flow control section 64 performed by the control section 40 will be described in details with reference to
As illustrated in
Consequently, a fluid supplied as a result of driving of the pump 41 passes through the first conduit 43, the supply port 45m, the introduction port 3i and the first fluid passage portion 3 and is discharged from the first discharge portion 3t only to the inside of the endoscope conduit 18 because only the first flow control section 63 is in an on state.
Here, since the second flow control section 64 is in an off state, no fluid is discharged from the second discharge portion 4t, and thus, the fluid is intensively supplied only to the inside of the endoscope conduit 18, enabling correct detection of clogging inside the endoscope conduit 18.
Next, when normal cleaning of the endoscope 10 is performed (cleaning mode 1), when the endoscope 10 is disinfected after cleaning, and furthermore, when the endoscope 10 is rinsed, the control section 40 performs control to turn on both the first flow control section 63 and the second flow control section 64.
As a result, any of the cleaning solution, the disinfectant solution and the rinse water supplied as a result of driving of the pump 41 passes through the first conduit 43, the supply port 45m, the introduction port 3i and the first fluid passage portion 3 and is discharged from the first discharge portion 3t to the inside of the endoscope conduit 18 because the first flow control section 63 is in an on state, and also passes through the second conduit 44, the supply port 45g, the introduction port 4i and the first fluid passage portion 4 and is discharged from the second discharge portion 4t to the circumference of the opening portion 17k of the pipe sleeve 17 because the second flow control section 64 is also in an on state.
Consequently, while the inside of the endoscope conduit 18 is cleaned, disinfected or rinsed, the pipe sleeve 17 is actively cleaned, disinfected or rinsed by means of the cleaning solution, the disinfectant solution or the rinse water discharged from the second discharge portion 4t. In this case, not only the pipe sleeve 17, but also an outer surface of the projection portion 6e of the endoscope connection portion 6 is cleaned, disinfected or rinsed.
Meanwhile, when only the inside of the endoscope conduit 18 is actively cleaned (cleaning mode 2), for example, when only the inside of the endoscope conduit 18 is actively cleaned and disinfected by means of high-pressure cleaning or supply of a known two-phase gas-liquid flow, the control section 40 performs control to turn on the first flow control section 63 and turn off the second flow control section 64 as in the case of clogging detection.
As a result, for example, the two-phase gas-liquid flow or the high-pressure fluid supplied as a result of driving of the pump 41 passes through the first conduit 43, the supply port 45m, the introduction port 3i and the first fluid passage portion 3 and is intensively discharged from the first discharge portion 3t only to the inside of the endoscope conduit 18 because only the first flow control section 63 is in an on state. Thus, only the endoscope conduit 18 is actively cleaned. An operation similar to the above operation is performed for a case where only the inside of the endoscope conduit 18 is disinfected or rinsed.
Furthermore, when only the pipe sleeve 17 is intensively cleaned (cleaning mode 3), the control section 40 performs control to turn on only the second flow control section 64 and turn off the first flow control section 63.
Consequently, the cleaning solution as a result of driving of the pump 41 passes though the second conduit 44, the supply port 45g, the introduction port 4i and the first fluid passage portion 4 and is discharged from the second discharge portion 4t to the inside of the endoscope conduit 18 because only the second flow control section 64 is in an on state.
Accordingly, since the first flow control section 63 is in an off state, no cleaning solution is discharged from the first discharge portion 3t, and thus, the pipe sleeve 17 is actively and intensively cleaned by the cleaning solution discharged from the second discharge portion 4t. An operation similar to the above operation is performed for a case where only the pipe sleeve 17 is disinfected or rinsed.
It has been described above that in the present embodiment, the endoscope cleaning/disinfecting apparatus connection tool 1 is configured so that, when the endoscope connection portion 6 is connected to the pipe sleeve 17, the first discharge portion 3t of the first fluid passage portion 3 is arranged inside the pipe sleeve 17 and discharges the fluid R to the endoscope conduit 18, and the second discharge portion 4t of the second fluid passage portion 4 is arranged at the circumference of the opening portion 17k of the pipe sleeve 17 and discharges the fluid R to the circumference of the opening portion 17k.
While in a conventional configuration, a fluid is supplied to a circumference of an opening portion 17k by means of the fluid being run out from the pipe sleeve 17, and thus, in order to clean the circumference of the opening portion 17k, it is necessary to increase the amount of fluid to be supplied, requiring a long time for the cleaning, in the configuration according to the present embodiment, the fluid R supplied via the second conduit 44 and the second fluid passage portion 4 as a result of the second flow control section 64 being turned on is exclusively and actively spayed to the circumference of the opening portion 17k from the second discharge portion 4t, enabling the circumference of the opening portion 17k to be cleaned in a short period of time.
Furthermore, since only the first discharge portion 3t is arranged inside the pipe sleeve 17, the fluid R supplied via the first conduit 43 and the first fluid passage portion 3 as a result of the first flow control section 63 being turned on is exclusively supplied to the inside of the endoscope conduit 18 from the first discharge portion 3t, enabling the inside of the endoscope conduit 18 to be cleaned in a short period of time.
Furthermore, it has been described that in the present embodiment, the control section 40 performs control to open/close the first flow control section 63 and the second flow control section 64, and also performs control the time periods during which the first flow control section 63 and the second flow control section 64 are opened.
Consequently, time periods during which the endoscope conduit 18 and the pipe sleeve 17 are cleaned/disinfected can be separately controlled, as well as the amount of supply of the fluid R to the endoscope conduit 18 and the amount of supply of the fluid R to the pipe sleeve 17 can be separately adjusted. Furthermore, the fluid R can be supplied selectively or simultaneously to the endoscope conduit 18 and the pipe sleeve 17, and thus, the endoscope conduit 18 and/or the pipe sleeve 17 can be actively cleaned/disinfected depending on the purpose of use. Thus, for example, cleaning/disinfection of only the pipe sleeve 17, which could not be performed conventionally, can easily be performed.
According to the above, the endoscope cleaning/disinfecting apparatus connection tool 1 and the fluid supply apparatus 100 that are configured to clean/disinfect the inside of the endoscope conduit 18 and actively clean/disinfect the pipe sleeve 17 of the endoscope 10 can be provided.
The fluid supply apparatus 100 proposed herein may be one that adjusts cleaning/disinfecting time of the pipe sleeve 17 and cleaning/disinfecting time of the endoscope conduit 18 according to the type and/or state of the endoscope. For example, an adjustment can be made to increase cleaning time or disinfecting time of the pipe sleeve 17 for endoscopes whose pipe sleeve portions generally easily get dirty. An adjustment can also be made to decrease time for cleaning or disinfecting a portion that is hard to get dirty.
Also, the fluid supply apparatus 100 proposed herein may have a function for reading information provided to an endoscope such as an RFID reading function, for example.
