The present invention relates to an automatic endoscope leakage inspection apparatus, and in particular to an automatic endoscope leakage inspection apparatus and an inspection method thereof, wherein the endoscope information on various endoscopes are managed by kinds, and an unique identification number of a predetermined endoscope is read out using a RF communication network, and one endoscope information corresponding to the read unique identification information is selected, thus automatically processing a leakage inspection of the endoscope.
The endoscope is referred to a device which is configured to inspect an internal body or surgically operate or is inserted into the inside of an internal organ and observe a corresponding internal organ, for example, a bronchus, a throat, a stomach, a heart, a large intestine, etc. which cannot be visually checked. There are various kinds of endoscopes which may be categorized, for example, by manufacturers, use purposes, sizes, etc. The endoscope is designed to observe a predetermined internal organ using a small-sized camera, for example, a CCD sensor, etc. For example, the endoscope is equipped with a scope unit at an end thereof, which is inserted into an internal body. The scope unit is formed of a CCD camera to obtain images, an angle unit for driving the motion of the CCD camera, and a light source which emits light to a predetermined subject.
For this, the endoscope is provided with a plurality of tubular passages through which a medicinal fluid, a gas, etc. are injected. Moreover, the endoscope is provided with a tubular passage into which a plurality of cables are inserted to control the motions of a small-sized camera or emit light.
Before the start of the operation, this endoscope necessarily needs a procedure to inspect any damage to the tubular passage. If a predetermined portion of the tubular passage is damaged, the scope unit may be exposed to a medicinal fluid or a gas which is being supplied to the tubular passage. In this case, it may cause a problem with the endoscope. In worse case, the whole components of the endoscope should be discarded, thus causing a critical financial problem. For this reason, the leakage inspection should be carried out before the operation.
In many typical hospitals, an endoscope leakage inspection is carried out using an endoscope washer which is configured to wash the endoscope before the endoscope is used for an operation, and if no abnormality, the endoscope is used for the operation. After the operation is finished, the leakage inspection should be carried out. If no abnormality, the washing and disinfection are carried out for the following reason. If the operation, washing or disinfection is carried out in a state where the endoscope has a leakage, water or mucus may enter the inside of the endoscope due to the leakage, thus causing a problem with various electronic components disposed inside of the endoscope, for example, a CCD, a camera, an angle adjusting device, a lighting device, etc.
The conventional endoscope leakage inspection device, however, may need a long inspection time and may be hard to locate the position of the leakage and may need a very professional skill, for which the reliability of the inspection may be degraded.
In order to resolve the aforementioned problems, the Korean patent registration number 10-1052893 (the laid-open date is Jul. 29, 2011) filed by the same applicant as the present invention describes the invention entitled “an endoscope leakage inspection apparatus and a leakage inspection method using the same”, wherein the endoscope leakage inspection apparatus is installed at the endoscope using a connector and is able to easily, accurately and fast inspect any leakage of the endoscope in an automatic manner.

The pressure adjusting unit 180 is equipped with a plurality of up and down buttons, thus adjusting the levels of the pressurization and measurement pressure of the tester 100a upwardly or downwardly. The automatic endoscope leakage inspection apparatus 100 in this embodiment may be set to pressurize on the inside tubular passage of the endoscope 10 via the inspection module 194 or adjust the pressure value measured by the pressure sensor 140 of the inspection module 194 in a pressure range of about 200-300 mmHg to the maximum; however it is able to adjust the range of the pressurization and measurement pressure value using the pressure adjusting unit 180 for the sake of being appropriate to various kinds of the endoscopes 10. For example, in case of the endoscope of the bronchus operation, the pressure of the tester 100a may be adjusted up to about 250 mmHg to the maximum.
The controller 102 is equipped with a microprocessor, a microcontroller, etc. The controller 102 is also equipped with a writable and readable memory 103 and is configured to set and store, in the memory 103, the endoscope information (103a in
In this embodiment, as illustrated in
The kinds of the endoscopes may set a gastro endoscope, a colono endoscope, a broncho endoscope, an ERCP endoscope and an ultrasonic endoscope. The serial number may contain the unique identification information contained in the RFID tag 30 provided at the endoscope 10. This serial number may be set different to various endoscopes.
The pressurizing pressure allows to set the maximum pressure value of the air which is supplied to the inside tubular passage in response to the inside tubular tube having different sizes of the endoscopes 10. The pressurizing time allows to set the leakage inspection time to determine the leakage inspection using the pressurizing pressure. The stabilization time allows to set the time that the air is supplied with the pressurizing pressure, and the pressure becomes the pressurizing pressure. Moreover, the reference pressure allows to set and store the error value of a permissible range to determine if the measured pressure value is an error in the permissible range.
The control program of the controller 102 may store the processing algorithm based on the endoscope leakage inspection mode of the tester 100a. For example, the endoscope leakage inspection mode may be formed of an automatic mode and a manual mode. If one endoscope leakage inspection mode is selected by the mode selection button 105, the controller 102 may inspect the leakage state of the endoscope 10 in any of the automatic mode wherein the leakage inspection is automatically carried out by reading out the unique identification information from the RFID tag 30 in response thereto and the manual mode wherein the leakage inspection is manually carried out by selecting the endoscope information via the same. Since this inspection method is described in the endoscope leakage inspection of the Korean patent registration number 10-1052893 (the laid-open data is Jul. 29, 2011), the detailed description thereon will be omitted. For example, the manual mode may be available if a small quantity of the endoscopes is provided or if the worker knows the serial number of the endoscope.
The electric power supply unit 110 may include a DC power unit 112 for receiving the AC power and supplying AC power, a battery 114 disposed inside of the tester 100a and configured to supply the DC power if the DC power unit 112 is not connected, a constant voltage circuit 116 for receiving the DC power supplied from the DC power unit 112 and the battery 114 and supplying the same in the form of a constant voltage, and a battery level detection circuit 118 for detecting the residual level of the power of the battery 114. The DC power unit 110 may be provided, for example, in the form of an electric power adaptor having an electric power plug and may be inserted in the electric power provided at one side of the housing 101 of the tester 100a or may be provided, for example, in the form of the electric power supply circuit which is disposed inside of the tester 100a and receives the AC power and supplies the same in the form of the DC power. If the residual amount of the electric power of the battery 114 is detected low, the battery level detection circuit 118 supplies a detection result to the controller 102.
The inspection module 194 may include an air supply unit 120 for supplying the air of a constant pressure to the inside tubular passage of the endoscope 10, a pressure sensor 140 for measuring any change in the pressure at the inside tubular passage of the endoscope 10, and a relief valve 170 disposed between the connection tube 150 and the pump 126, thus maintaining a stable pressurization.
The air supply unit 120 may include a motor driving circuit 122, a motor 124 and a pump 126 which are provided so as to supply the air of a constant pressure to the inside tubular passage of the endoscope 10. The motor 124 and the pump 126 may be provided in an integrated form. The motor driving circuit 122 is able to drive the motor 124 in response to a control of the controller 102. The motor 124 may operate the pump 126 in response to a constant pressure (for example, about 300 mmHg). The pump 126 may allow to supply the air of a constant pressure to the inside tubular passage of the endoscope 10 via the connection tube 160 and the connection adaptor 170.
The air supply unit 120 may include a valve driving circuit 130 and a solenoid valve 132 both for discharging the pressurized air from the inside tubular passage of the endoscope 10. The valve driving circuit 130 is able to open or close the solenoid valve 132 in response to a control of the controller 102. The solenoid valve 132 may be connected to the connection tube 160. If the leakage inspection is completed by the tester 100a, the valve driving circuit 130 opens the solenoid valve 132 and discharge the air supplied to the inside tubular passage of the endoscope 10. The valve driving circuit 132 may periodically open the solenoid valve 132 for a leakage inspection time for the sake of the repeated inspection in the automatic mode after the air of a constant pressure has been supplied to the inside tubular passage.
The pressure sensor 140 is able to measure the pressure in real time or periodically of the inside tubular passage of the endoscope 10. The pressure sensor 140 may be substituted with a sensor, a flow rate sensor, etc. which are able to measure any change to the flow rate of the air pressurized to the inside tubular passage of the endoscope 10. In this way, the pressure sensor 140 may measure the pressure of the inside tubular passage in response to a control signal from the controller 102 and convert a result of the measurement into an electric signal and output it to the controller 102.
As the leakage inspection is completed, the alarm unit 108 may output the normal state of the endoscope 10 or the leakage occurrence state in the form of an audio signal. For example, if the endoscope 10 is determined as a normal state as a result of the inspection, the alarm unit 108 may output an alarm sound once, and if the endoscope 10 is in a leakage state, it may output the alarm sound three times. Moreover, the alarm unit 108 may be configured to output another type of the alarm sound if the residual level of the battery is a low level.
The relief valve 170 is employed to protect the tester 100a and the endoscope 10 in such a way that the relief valve 170 is automatically opened and discharges air if the air the pressure value of which is over the maximum permissible pressure value, is supplied to the inside tubular passage of the endoscope 10, wherein the value of the pressure is pressurized by the pump 126 in case where an error occurs at the endoscope 10.
Moreover, the display unit 104 may be formed of a LCD device and is able to display various information. The display unit 104 may be further equipped with a plurality of light emitting diodes (LED).
As illustrated in
As illustrated in
The display unit 104 may display an electric power supply state, an error occurrence state, an inspection on-going state, a battery low level state, etc. using a plurality of the light emitting diodes (not illustrated).
As described above, the endoscope leakage inspection apparatus 100 according to the present invention is able to easily inspect the leakage occurrence state in such a way to read out a unique identification information with respect to the endoscope 10 from the RFID tag 30 disposed at the endoscope 10 using the RFID module 192 and pressurize the air of a constant pressure to the inside tubular passage of a corresponding endoscope 10 by determining the kinds of the endoscope via the same. The endoscope leakage inspection apparatus 100, therefore, is able to confirm a leakage portion of the endoscope in such a way to proceed with a leakage inspection using the automatic mode, recognize the leakage occurrence state of the endoscope 10, input the endoscope 10 equipped with the endoscope leakage inspection apparatus 100 if the leakage has occurred, into a processing tank (not illustrated) filled with water and then pressurize the air to the inside tubular passage of the endoscope using the manual mode.
Continuously,
Referring to
In a step S302, if the endoscope 10 is mounted on the tester 100a, an inspection mode is selected to determine if the leakage inspection with respect to the endoscope 10 mounted in the step S304 is carried out in the automatic mode or the manual mode.
If the inspection mode is selected as the automatic mode, this procedure goes to the step S306, and the RFID tag 30 of the mounted endoscope 10 is read out using the RFID module 192, and in a step S308, the endoscope information corresponding to the unique identification information read out from the RFID tag 30 will be automatically selected.
If the inspection mode is selected as the manual mode, this procedure goes to the step S316, and the kind of the endoscope which will be subjected to the leakage inspection may be selected. At this time, if the kind of the endoscope is selected, the endoscope information based on the selected endoscope will be automatically selected. This procedure is appropriate if the kinds or a small quantity of the endoscopes are provided or the worker knows the kinds of the mounted endoscope or the serial number.
If the endoscope information is selected automatically or manually, the automatic leakage inspection is carried out in the steps S310 to S314. If the inspection is completed, a result of the inspection will be displayed. As illustrated in
Referring to
The average pressure values of the pressures measured at the unit time interval in the step S326 are calculated, and any deviation with respect to the average pressure value is calculated in a step S280.
In a step S330, it is determined if the deviation calculated in the step S330 is within a permissible error range. This may be determined in such a way to compare to the deviation set and stored at the controller 102. As a result of the determination, if the calculated deviation is a valve within a permissible error range, this procedure will go to the step S332, and the normality or checked state will be displayed or reported through the display unit 104 and the alarm unit 108. If the calculated deviation is not a value within a permissible error range, the procedure will go to the step S334, and the leakage occurrence state will be displayed and reported through the display unit 104 and the alarm unit 108.
The endoscope leakage inspection method in the automatic mode may require about 30-40 seconds for the pressurization, stabilization, inspection and determination. In this way, the leakage state of the endoscope 10 can be quickly inspected.
Since only the leakage occurrence state of the endoscope 10 is inspected in the automatic mode of the present invention, it is possible to quickly and easily recognize the leakage occurrence state in such a way to engage the endoscope 10 to the automatic endoscope leakage inspection apparatus 100 at any time before or after the surgical operation.
As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
