Description

TECHNICAL FIELD

[0001] The present invention relates to a fluid dispenser for a reprocessing device for reprocessing surgical instruments, in particular endoscopes. Furthermore, the present invention relates to a reprocessing device for reprocessing surgical instruments, in particular endoscopes, and to the use of a fluid dispenser in a reprocessing device. BACKGROUND

[0002] It is known in the prior art that endoscopes are used for diagnosing and treating illnesses. After use of endoscopes and other surgical instruments on a patient, in order to use these surgical instruments, they have to be reprocessed, i.e. cleaned and disinfected.

[0003] In the case of reprocessing surgical instruments, legal and clinical regulations have to be strictly adhered to, so that the components on the surface of the surgical instruments, in particular endoscopes, and in the internal channels have to be disinfected and must be free of germs, bacteria, etc.

[0004] In particular endoscopes, the reprocessing device for surgical instruments has a device for cleaning and disinfecting the outer surface as well as the internal channels and channel systems of the surgical instruments using appropriate liquids. For this purpose, a rinsing cycle is usually provided. In particular, in the case of internal channel rinsing of the surgical instruments, in particular of the internal channels of the endoscope or of the individual flexible endoscopes, the hygienic result of the reprocessing depends on the flow volume of the reprocessing fluid. Liquids or gases can be used as reprocessing fluid.

[0005] A reprocessing device known from Olympus Winter & Ihl GmbH, Hamburg, under the name ETD is used for reprocessing and disinfecting flexible endoscopes. In this reprocessing device, the channels of the endoscope are rinsed with a reprocessing fluid or the endoscope, in particular the flexible endoscope, is mechanically cleaned and disinfected with rinsing, cleaning and / or disinfecting liquids, respectively.

[0006] When reprocessing surgical instruments, in particular endoscopes, it is particularly important to clean and disinfect the channels of the endoscope. For reprocessing the surgical instruments, the channels of the surgical instruments are connected to a rinsing circuit of the reprocessing device. For reprocessing the channels of the endoscope, the channels are connected to adapters which receive baskets in which the endoscope to be cleaned is arranged so that the channels are connected to the rinsing channels of the rinsing circuit or the adapters are connected to the counterpieces of the rinsing circuit when the receiving baskets with the endoscope to be cleaned are introduced into a rinsing chamber of the reprocessing device, subsequently.

[0007] The channels of the endoscope are coupled to the rinsing circuit provided in the rinsing chamber by plug-in couplings or screw joints, wherein the channels are connected individually and sequentially to the lines of the rinsing circuit. Furthermore, the adapters and the counterpieces can be connected to each other.

[0008] There are shut-off valves, Y-hose connections or directional valves for bypassing and joining in a time-consuming and frequently loss-intensive manner for supplying fluid, in particular liquid and gas, into channels to be cleaned and / or dried, or into a corresponding flushing circuit. In this case, the fluid flows through the channels and can be distributed to a plurality of hoses.

[0009] In addition, a fluid distributor for a reprocessing device for reprocessing surgical instruments is known from DE 102 015 203 429 A1. Furthermore, DE 102 011 082 776 A1 discloses a device for flushing channels of an endoscope. SUMMARY

[0010] It is an object of the application to provide a modular fluid distributor and a reprocessing device for reprocessing surgical instruments, in particular endoscopes, wherein the fluid distributor should be used in a flexible manner for cleaning and / or drying a plurality of channels, or respectively for reprocessing of surgical instruments.

[0011] This object is achieved by a fluid distributor for a reprocessing device for reprocessing surgical instruments, in particular endoscopes, in particular having an outer fluid delivery body, wherein the fluid delivery body has a plurality of individual connections, each for one channel of a surgical instrument to be cleaned and / or dried, wherein a preferably linearly movable fluid switching body is arranged in the fluid delivery body, wherein the fluid switching body has a supply line inside, which can be connected or is connected to a fluid reservoir for a preferably liquid or gaseous fluid to the connections of the fluid delivery body, wherein the movable fluid switching body is configured such that, in a preferably first position of the fluid switching body in the fluid delivery body, a plurality of connections or all connections of the fluid delivery body are simultaneously fluidically connected to the supply line of the fluid switching body, so that fluid can be simultaneously supplied via one supply line of the fluid switching body to a plurality of connections or all connections of the fluid delivery body, and in at least one further position of the fluid switching body in the fluid delivery body, preferably exclusively, one connection of a plurality of connections of the fluid delivery body is fluidically connected to the supply line of the fluid switching body, so that fluid can be supplied via one supply line of the fluid switching body to one connection of the fluid delivery body.

[0012] The present application is based on the idea that, with the aid of a fluid distributor according to the application, a plurality or all of the connections of the fluid delivery body are selectively fluidically connected to the supply line of the fluid switching body at the same time, or only individual connections of the fluid delivery body are fluidically connected to the supply line of the fluid switching body. Preferably, therefore, the outer fluid delivery body is designed as a fluid distribution body of the type having a plurality of connections for passages of surgical instruments to be cleaned and / or dried, such that, depending on the placement or respective position of the fluid switching body within the fluid delivery body, the connections of the fluid delivery body are connected or respectively fluidically coupled to the supply line of the fluid switching body. In particular, given n (n = 2, 3, 4, 5...) connections on the fluid delivery body, the fluid switching body can be positioned or respectively can be positioned in (n + 1) positions inside the fluid delivery body in order to fluidically connect all of the connections of the fluid delivery body to the supply line of the fluid switching body at the same time, or to fluidically connect each of the connections of the fluid delivery body individually or respectively to the supply line of the fluid switching body.

[0013] In the context of the present application, the fluid delivery body and the fluid switching body can be moved or can be moved relative to one another for a change in position of the fluid switching body within the fluid delivery body.

[0014] In one position of the fluid switching body within the fluid delivery body, liquid or gaseous fluid is supplied, for example, from a fluid reservoir into the central hollow cylinder of the fluid delivery body, wherein only one open connection of the fluid delivery body is connected to a passage of a surgical instrument to be flushed via the supply line or respectively the flushing line, wherein, in one embodiment, the supply of fluid is monitored. The supply of fluid is controlled by a movable fluid switching body, which is designed, for example, as a movable tube, such that the fluid flows through all connections at the same time or only through one outlet of the fluid delivery body in each case.

[0015] With the aid of a fluid distributor according to the application, it is possible to variably flush passages of surgical instruments, wherein the monitoring of the treatment in a reprocessing device for surgical instruments, or respectively in a cleaning and disinfection device, or respectively in a drying and storage device, is improved in a simple manner.

[0016] When cleaning and / or reprocessing surgical instruments, depending on the processing steps to be performed, rinsing liquid and / or rinsing gas is supplied to the channels of the surgical instruments as a fluid for the respective processing by means of the fluid distributor. During the reprocessing of the surgical instruments, in one aspect, a leak test is also provided, in which a fluid, in particular a liquid, is supplied, for example, to the interior of the channels of the endoscope, which can also be performed using the fluid distributor. In this process, the pressure of the fluid is monitored, for example, during the reprocessing process or respectively during the leak test by means of a sensor.

[0017] In the context of the present application, it is possible that the fluid distributor according to the present application is used in a drying device, in particular a drying cabinet, and / or a storage device, in particular a storage cabinet. In this case, for example, drying air or compressed air is introduced as a fluid on the input side, is guided via the fluid switching body of the fluid distributor to at least one connection of the fluid delivery body, which is connected with the fluid delivery body, and to one or all channels in the housing instrument, in particular the endoscope, in order to dry one or more channels of the surgical instrument after a cleaning and disinfection process, for example, in a cleaning and disinfection device. Depending on the arrangement or positioning of the fluid switching body in the fluid delivery body, the preferably drying air or compressed air is applied to one or more, in particular all, connections of the fluid delivery body. In the case of a drying device, in particular a drying cabinet, and / or a storage device, in particular a storage cabinet, for surgical instruments, a gaseous fluid, in particular drying air or compressed air, is used as a processing fluid.

[0018] Furthermore, in the context of the present application, the fluid distributor can also be used for leak protection measures, for which purpose the pressure curve in the interior of the surgical instrument or the pressure curve in the individual channels is measured. In this case, the fluid distributor according to the present application is used to apply a fluid, in particular air, to the individual channels of the surgical instrument in order to detect or determine the leak protection of the instrument depending on the measured pressure curve in the individual channels of the surgical instrument. In addition, a fluid, in particular gaseous, such as air, can also be applied simultaneously to all individual channels in the corresponding positions of the fluid switching body. This enables the leak protection of the channels of the surgical instrument or the leak protection of the interior of the surgical instrument to be monitored, respectively.

[0019] Furthermore, the fluid distributor according to the present application also enables the detection of blockages of the individual channels of the surgical instrument, in particular the endoscope, in a simple manner, for example, during the reprocessing by the corresponding processing fluid and / or drying.

[0020] It is further provided in accordance with a further aspect in the context of the present application that by means of the fluid dispenser, it is possible to check and / or monitor the coupling of individual or all channels of the endoscope to be flushed with the adapter for the channels of the endoscope. This can be done both during cleaning and during drying of the channels of the endoscope. Thus, for example, it is possible to detect or discover a failure of the connection from the adapter to the endoscope in a simple manner.

[0021] To this end, it is provided in the development of the fluid dispenser that the fluid switching body is movable in the fluid delivery body such that when the fluid switching body is in a first position in the fluid delivery body, all connections of the fluid delivery body are simultaneously, in particular in parallel, fluidically connected to one supply line of the fluid switching body, and after the fluid switching body is moved from the first position into a further position, preferably an alternative position of the fluid switching body in the fluid delivery body, one of the connections of the fluid delivery body for each channel to be cleaned and / or dried is fluidically connected to one supply line of the fluid switching body individually.

[0022] In order to fluidically connect the connections of the fluid delivery body to the supply lines of the fluid switching body in a simple manner, it is advantageously provided in accordance with a further aspect that the fluid switching body is linearly movable within the fluid delivery body. In order to clean or flush the channels of a surgical instrument, in particular an endoscope, which are connected to the connections of the fluid delivery body, for example, via corresponding flushing lines, the fluid switching body is connected to a reservoir for handling fluid, in particular liquid or gas, for example, such that the handling fluid flows out of the reservoir to be guided through the supply lines of the fluid switching body to the open connections of the fluid delivery body.

[0023] To this end, in one embodiment, it is provided that the supply lines of the fluid switching body are designed as preferably hollow cylindrical tubes or have a preferably hollow cylindrical tube portion which is accommodated in the fluid delivery body. In this case, depending on the placement or position of the movable fluid switching body, the supply lines or the respective tubes or tube portions are at least partially received in the interior of the fluid delivery body.

[0024] In order to guide the liquid or gaseous fluid from the reservoir to the connections of the fluid delivery body, it is provided in accordance with the development of the fluid dispenser that in the fluid delivery body, the tube of the fluid switching body or the tube portion of the fluid switching body is sealed against the interior of the fluid delivery body on the end side or front side using a seal, in particular a sealing lip or an O-ring, wherein in particular the seal is designed as an annular collar. In particular, the annular collar is designed as a seal on the front surface outlet of the fluid switching body.

[0025] Furthermore, one embodiment of the fluid dispenser differs in that the tube has a front surface outlet in the fluid delivery body or the tube portion has a front surface outlet in the fluid delivery body. The fluid is guided through the outlet of the tube or respectively of the tube portion to the opening of the connection of the fluid delivery body.

[0026] In one embodiment of the fluid dispenser, it is also preferred that inside the fluid delivery body, a preferably linear, movable, in particular disc-shaped sealing cover is provided, which interacts with the outlet of the tube or with the outlet of the tube portion, wherein in particular the sealing cover is connected to the tube or to the tube portion and arranged at a predetermined distance from the outlet of the tube or from the outlet of the tube portion. By means of the sealing cover, it is achieved that inside the fluid delivery body, with corresponding positioning of the fluid switching body, only one connection of the fluid delivery body is fluidically connected to the supply line of the fluid switching body. Thus, the fluid from the fluid reservoir only flows through one connection of the fluid delivery body, wherein the tube or the tube portion of the fluid switching body together with the sealing cover is sealed against the interior of the fluid delivery body.

[0027] In a preferred exemplary embodiment, it is provided that the sealing cover is connected to the tube or to the tube portion at a predetermined distance, wherein the sealing cover is also moved or can be moved simultaneously with the movement of the fluid switching body. In particular, the sealing cover is connected to the fluid switching body via at least one spacer. The sealing cover is here arranged at a predetermined constant distance from the front face (with the outlet) of the fluid switching body.

[0028] To this end, it is provided in the development that the sealing cover is sealed against the interior of the fluid delivery body using a seal, in particular a sealing lip or an O-ring, on the circumferential edge of the sealing cover.

[0029] According to a further aspect, alternatively, the fluid delivery body has an elongated, in particular cylindrical or hollow-cylindrical tube body, which has an interior for receiving the fluid switching body and at least one flow chamber, which is connected to the tube body for receiving the end of the fluid switching body, wherein in particular the tube body is arranged between two flow chambers. In the context of the present invention, it can be provided here that when the fluid switching body is arranged in the flow chamber, all connections of the delivery body are fluidically connected to the supply line.

[0030] It is further provided in one embodiment of the fluid dispenser that the tube body has a plurality of connection portions arranged next to each other, each connection portion for a channel of the surgical instrument, preferably at equidistant distances, and / or the at least one flow chamber has a connection portion for a channel of the surgical instrument. For example, if two flow chambers are arranged on each end of the tube body, it is provided in the context of the present application that, with respect to the flow direction of the fluid, the first flow chamber is in fluid communication only with the tube body and the flow chamber downstream or on the output side after the tube body has a connection portion for a channel of the surgical instrument.

[0031] In particular, the interior of the tube body of the fluid transport body has a cross-section and the interior of the flow chamber has a cross-section, wherein the cross-section of the interior of the tube body is smaller than the cross-section of the interior of the flow chamber arranged parallel thereto.

[0032] Preferably, a drive for the fluid switching body is provided to move the fluid switching body, wherein the drive is designed as a mechanical drive or an electrical drive or a pneumatic drive or a hydraulic drive.

[0033] An embodiment of the fluid dispenser is further distinguished in that a position sensor device is provided for detecting at least one position or a plurality of positions of the fluid switching body within the fluid transport body, wherein the position sensor device is designed as an optical sensor or a mechanical working sensor or an electrical sensor.

[0069] In the drawings, in each case identical or similar elements and / or components are provided with the same reference signs so that they need not all be presented again in every case.

[0070] Figure 1 A fluid dispenser 10 for a respective fluid, for example a liquid or a gas, is shown. The fluid dispenser 10 is a component of the schematically shown reprocessing device A for an endoscope 100. Here, the endoscope 100 has a channel to be cleaned and disinfected.

[0071] To this end, a rinsing fluid is conveyed from a rinsing agent reservoir 50 to the fluid dispenser 10 by means of a pump 52. The fluid dispenser 10 has an outer fluid dispensing body which has a first flow chamber on the input side which is connected to a tube drum. On the output side, the tube drum is connected to a flow chamber 18. The flow chamber 18 also has a connection 20.8 which is connected to a rinsing line 130 of the endoscope.

[0072] The tube drum also has connections 20.1 to 20.7 along its longitudinal extension which are connected to the respective rinsing lines 130. As an example for illustration, in Figure 1 only four rinsing lines 130 are shown. The rinsing lines 130 themselves are provided with a respective connection to the endoscope 100 in order to clean or disinfect a respective channel in the endoscope 100, which is not shown here.

[0073] On the inner side of the fluid dispenser 10, a fluid switching body 30 is arranged which is linearly movable within the fluid conveying body 12. The fluid switching body 30 is designed as a hollow cylindrical tube so that inside the fluid switching body 30 a supply line 32 is designed which is connected to the rinsing agent reservoir 50 on the input side via the pump 52. The fluid switching body 30 is also sealed on the input side of the (first) flow chamber.

[0074] A front outlet 34 is designed on the output side of the supply line 32 so that rinsing fluid taken from the rinsing agent reservoir 50 is discharged from the front outlet 34. A collar seal 36 is arranged on the outer side in the area of the front outlet 34 so that the front outlet 34 of the supply line 32 is designed to be opposite the interior of the fluid conveying body 12 in the area of the tube drum.

[0075] Further, at a predetermined distance on the output side of the front outlet 34, a sealing cap 38 is arranged, which is also designed with a circumferential seal 40 on its outer side. The sealing cap 38 is firmly connected to the front of the supply line 32 by means of a spacer 48.

[0076] In Figure 1 which the fluid switching body 30 is arranged in the (end) position in the fluid delivery body 12 such that the front outlet 34 faces the (second) flow chamber 18 and the flushing fluid conveyed through the supply line 32 is introduced into the flow chamber 18. The cross section of the flow chamber 18 here is larger than the cross sectional surface of the sealing cap 38. As a result, the flushing medium flows via the front outlet 34 through the supply line 32 into the flow chamber 18, wherein the flushing medium is supplied only at the end side via the outlet 20.8 of the flushing line 130 connected thereto, whereby when the fluid switching body 30 is in the Figure 1 position shown, the corresponding connected channels of the endoscope 100 are flushed. According to Figure 1 the position of the fluid switching body 30 shown, flushing fluid is applied to the other outlets 20.1 to 20.7.

[0077] An additional representation of the fluid distributor 10 is shown in Figure 2 and Figure 3 , wherein the linearly movable fluid switching body 30 is shown in the respective positions here.

[0078] In Figure 2 the (starting) position of the fluid switching body 30 shown, the front outlet 34 of the supply line 32 is arranged within the first flow chamber such that when the flushing fluid is delivered, the flushing fluid flows through all outlets 20.1 to 20.8 of the fluid delivery body 12 at the same time, so that all channels of the endoscope 100 are flushed at the same time.

[0079] Then, if the fluid switching body 30 is moved linearly in the direction of the second flow chamber 18 by means of the drive 46, in each case the flushing medium flows continuously only through the individual outlet 20.1 to 20.8 in the respective (intermediate) position. According to the placement of the fluid switching body 30 within the fluid delivery body 12, the connections 20.1 to 20.8 are activated individually here, so that the flushing fluid is always directed only to one of the connections 20.1 to 20.8 to be flushed and via the individual open connection 20.1 to 20.8 to the channels of the endoscope 100 located behind or respectively connected to said connection.

[0080] In Figure 3 , the fluid switching body 30 is positioned such that the flushing medium flows only through the outlet 20.2, while the flushing medium does not flow through the other outlets 20.1, 20.3 to 20.8.

[0081] For detecting the position of the fluid switching body 30, a measuring sensor 42 is arranged, for example, in the first flow chamber, by means of which the respective positioning of the fluid switching body 30 within the fluid transport body 12 is detected. Corresponding measurement data from the measuring sensor 42 are transmitted in this case to a corresponding controller 44 of the reprocessing device.

[0082] The drive 46 for the fluid switching body 30 can be designed as an electric or hydraulic or pneumatic or mechanical drive in order to move the fluid switching body 30 linearly back and forth within the fluid transport body 12 along the longitudinal extension of the fluid transport body 12.

[0083] In Figure 4 , the fluid distributor 10 for the drying and storage device B of the endoscope 100 is schematically shown as a further exemplary embodiment. In Figure 4 , the fluid distributor 10 is correspondingly configured in the drying and storage device B of the endoscope 100, as shown in Figure 1 , so that the previous explanations of the fluid distributor 10 in Figures 1 to 3 can be similarly applied.

[0084] For drying the individual channels 20.1 to 20.8 of the fluid transport body 12 and the channels of the endoscope 100 with a treatment fluid, in particular air or compressed air, depending on the position of the fluid switching body, a treatment fluid reservoir 150 is provided, which is connected to the fluid switching body 30 or to its supply line 32, respectively. A valve 152 and a sensor 153 are arranged in the connection between the treatment fluid reservoir 150 and the supply line 32.

[0085] The treatment fluid flows from the treatment fluid reservoir 150 through the opening of the valve 152 to the outlet 20.8. The pressure of the treatment fluid in the line is measured by the sensor 153. The sensor 153 is also connected to a leak test 151 to test the leak tightness of the channels of the endoscope 100 connected to the outlet 20.8. The leak test 151 can be a component of the control unit of the drying and storage device B.

[0086] When the fluid switching body 30 is positioned in the flow chamber 14 (see Figure 2 ), the treatment fluid is applied to all channels of the endoscope 100 connected to the outlets 20.1 to 20.8. Depending on the positioning of the fluid switching body 30 in the tube body 16 (see Figure 3 ), the treatment fluid is supplied to the individual channels of the endoscope 100 via the respective outlets 20.1 to 20.8.

[0087] The features mentioned, including those described separately, and those defined in connection with one another, are deemed to be essential to the invention, either individually or in combination. Embodiments according to the invention can be realized by means of a single feature or a combination of several features.
