Description

  The present invention relates to a cleaning holder used for performing a large number of cleanings (decontamination / washing) of various tubular medical devices that are repeatedly used by cleaning / sterilization after use, The present invention relates to a cleaning method using a holder.

  Tubular medical instruments that are cleaned and sterilized after use and used repeatedly include, for example, various suction tubes used in otolaryngology and neurosurgery, cleaning tubes used in ophthalmology and oral surgery, catheters, surgical instruments, There are some medical tubes. However, these tubular medical devices are usually brushed by injecting a cleaning solution into each tubular medical device with a syringe or the like. However, since each tube is cleaned by hand, it takes a lot of time and effort. In addition, there is a drawback that there are individual differences and reliability is poor. For this reason, in recent years, automatic cleaning methods such as spray cleaning, ultrasonic cleaning, and suction cleaning have been frequently used.

  In this automatic cleaning method, tubular medical devices are accommodated in a basket of an injection cleaning machine or an ultrasonic cleaning machine and cleaned by immersing the basket in a cleaning tank in the same manner as cleaning of general medical instruments such as forceps and scalpels. However, since the tubular medical devices in the basket are loaded sideways, there is a problem that the cleaning liquid is hard to be filled in the lumen of each tubular medical device, and bubbles are likely to remain in the interior, resulting in poor cleaning. there were. Therefore, as an improved method, by connecting one end side of the tubular medical device via an adapter to the injection port of the cleaning liquid injection tube and the suction port of the suction pipe disposed in the cleaning tank of the cleaning machine, A method of ejecting the cleaning liquid from the ejection port into the cleaning tank through the cavity or conversely sucking the cleaning liquid in the cleaning tank is becoming widespread. In addition to the system (Patent Document 1) in which the tubular medical device is connected by such an adapter, a system (Patent Documents 1 and 2) is used to connect a plurality of tubes at the same time using an adapter having a branch channel. ) Has also appeared.

  However, in the conventional system in which the tubular medical device is connected to the spray port of the cleaning liquid spray tube of the cleaning tank or the suction port of the suction pipe via an adapter, the cleaning liquid is reliably washed through the lumen of the tubular medical device. Although it is possible, since the end shape and caliber differ depending on the type of tubular medical device, a special adapter is required for each type, and various adapters are manufactured when multiple types of tubular medical devices are to be cleaned. However, the cost is high, and it takes time and effort to connect one by one, and the efficiency is poor. Further, since the number of connections is limited to about 10 at most, the processing efficiency is not sufficient.

  In view of the above-described circumstances, the present invention is intended to clean dozens of tubular medical devices with a very simple operation, and collectively collect different types of tubular medical devices. It is an object of the present invention to provide a cleaning holder capable of reliably cleaning a cavity and a cleaning method using the cleaning holder.

  If means for achieving the above object is shown with reference numerals in the drawings, the cleaning holders H1 and H2 of the tubular medical device according to the first aspect of the present invention are a pair of coaxially held holders that are relatively rotatable. Mounting ring bodies 1 and 2 and a cylindrical sheet 3 made of a flexible material disposed inside these mounting ring bodies 1 and 2, and one end 3 a of the cylindrical sheet 3 is one mounting ring. The other end portion 3b is fixed to the body 1 and the other mounting ring body 2 over the entire circumference, and the cylindrical seat 3 can be attached to both the mounting ring bodies 1 and 2 from an unconstrained state having a substantially cylindrical shape. Can be converted into a constrained state in which the intermediate part 30 is constricted by being twisted, and a plurality of tubular medical devices T1, T2 having both ends opened inside the unconstrained tubular sheet 3. To convert the cylindrical sheet 3 into a restrained state The tubular medical devices T1 and T2 are automatically bundled by the intermediate portion 30 in which the tubular sheet 3 is narrowed and restrained and held in close contact with each other. By supplying L so that the open ends e1 of the tubular medical devices T1 and T2 are immersed in the liquid, the cleaning liquid L passes through the insides of the tubular medical devices T1 and T2 and is led to the other open end e2. It is comprised as follows.

  The invention of claim 2 is configured such that the tubular sheet 3 is made of a flexible material having rubber elasticity in the cleaning holders H1 and H2 of the tubular medical instrument of claim 1 described above.

  According to a third aspect of the present invention, in the cleaning holders H1 and H2 for the tubular medical device according to the second aspect, both the ring bodies 1 and 2 are configured to be relatively displaceable in the axial direction.

  According to a fourth aspect of the present invention, in the cleaning holders H1 and H2 of the tubular medical device according to any one of the first to third aspects, the attachment ring body 1 on the introduction side of the cleaning liquid L is attached to the mounting ring body 1 rather than the edge of the cylindrical sheet 3. The liquid storage cylinder frames 4A and 4B constituting the annular peripheral wall portions 41 and 42 rising outward in the axial direction are configured to be fitted in a liquid-tight manner.

  According to a fifth aspect of the present invention, in the cleaning holder H2 for the tubular medical device according to any one of the first to third aspects, both the mounting ring bodies 1, 2 are provided with annular grooves 11a, 11b and male screw portions 12a, 12b on the outer periphery. The end portions 3a and 3b of the tubular sheet 3 are folded outward so as to cover the annular grooves 11a and 11b of the mounting ring bodies 1 and 2, and the O-ring 5 is formed on the annular groove from above. The fastening cylinders 6 and 7 having internal thread portions 13a and 13b are fitted into the mounting ring bodies 1 and 2 and are fitted into the fixing ring bodies 1 and 11b. The O-ring 5 is in close contact with the circumferences 6a and 7a.

  The tubular medical device cleaning method according to the invention of claim 6 is the cleaning holder H1, H2 according to any one of claims 1 to 5, with one end side of the unconstrained tubular sheet 3 facing upward. Arranged on the instrument receiving members 8A and 8B, a plurality of tubular medical instruments T1 and T2 having both ends opened inside the cylindrical sheet 3 are erected in such a manner that the lower ends are supported by the instrument receiving members 8A and 8B. After that, the tubular sheet 3 is converted into a restrained state by relative rotation of the mounting ring bodies 1 and 2 so that the tubular medical devices T1 and T2 are bundled by the intermediate portion 30 of the tubular sheet 3 and are in close contact with each other. In this restraint holding posture, the cleaning liquid L is supplied from one end side of the tubular sheet 3 in such a manner that one open end e1 of each of the tubular medical devices T1 and T2 is immersed in the liquid. Tubular medical instruments T1, T2 Parts in was passed is characterized by to flow out from the other open end e2.

  According to a seventh aspect of the present invention, in the tubular medical instrument cleaning method according to the sixth aspect, the bent medical section T1 of the tubular medical instrument T1 bent in a U-shape is higher than the intermediate section 30 of the tubular sheet 3. The configuration is such that it stands upright.

  The effects of the present invention will be described below with reference numerals in the drawings. First, in the tubular medical device cleaning holders H1 and H2 according to the invention of claim 1, by rotating both the mounting ring bodies 1 and 2 relative to each other from an unconstrained state in which the cylindrical sheet 3 forms a substantially cylindrical shape, The tubular sheet 3 can be converted into a restrained state in which the intermediate portion 30 is constricted by being twisted. Therefore, if a plurality of tubular medical devices T1 and T2 whose both ends are opened inside the tubular sheet 3 in an unconstrained state and the tubular sheet 3 is converted into a restrained state, these tubular medical devices T1 , T2 are automatically bundled and held tightly by the intermediate portion 30 where the cylindrical sheet 3 is narrowed. If the cleaning liquid L is supplied from one end side of the tubular sheet 3 in this restraint holding posture in such a manner that one open end e1 of each of the tubular medical devices T1 and T2 is immersed in the liquid, the tubular sheet 3 is narrowed. Since the gap between the bundled tubular medical devices T1 and T2 is very small in the intermediate portion 30, most of the cleaning liquid L passes through the inside of each tubular medical device T1 and T2, and the other side. As a result, the lumens of the tubular medical devices T1 and T2 are reliably cleaned.

  Thus, according to the cleaning holders H1 and H2, the tubular medical devices T1 and T2 are placed in the tubular sheet 3 from the unconstrained state regardless of the number of the tubular medical instruments T1 and T2 placed on the inner side of the tubular sheet 3. Just by switching to the constrained state, the central part 30 is tightly bundled and constrained and held, so even a large number of dozens can be washed at the same time without any trouble, and high processing efficiency can be obtained with a simple operation. Even different items can be cleaned at once. The difference in the types of the tubular medical devices T1 and T2 includes not only the difference in end shape and diameter, but also the difference in outer diameter, the presence or absence of bending, the position and degree of bending, and the difference in length. To do. Further, the cleaning holders H1, H2 are structurally very simple and can be manufactured at low cost, and an adapter corresponding to the type of the tubular medical devices T1, T2 as in the prior art is unnecessary. By using H2, the equipment cost and member cost as a cleaning device can be greatly reduced as compared with the conventional case.

  According to the invention of claim 2, since the tubular sheet 3 is made of a flexible material having rubber elasticity, the bundle of the tubular medical devices T1, T2 is strongly strengthened by the elastic contraction force in the restraining posture of the tubular sheet 3. Tighten and restrain.

  According to the invention of claim 3, in the configuration in which the cylindrical sheet 3 is made of a flexible material having rubber elasticity, the cylindrical sheet 3 expands and contracts due to the relative displacement in the axial direction of both the mounting ring bodies 1 and 2. Since the tightening force in the restrained state increases or decreases depending on the degree of expansion / contraction, the tightening force can be appropriately adjusted according to the number of restraints of the tubular medical devices T1, T2.

  According to the fourth aspect of the present invention, the liquid storage tubular frames 4A and 4B that are liquid-tightly fitted to the mounting ring body 1 on the introduction side of the cleaning liquid L are axially outer than the edge of the cylindrical sheet 3 during cleaning. Since the annular peripheral wall portions 41 and 42 rising to the side can be formed, even when the opening end of the restrained tubular medical device T1 or T2 on the side of the cleaning liquid L is located beyond the edge of the cylindrical sheet 3, it can be cleaned. Accordingly, the allowable range of the lengths of the tubular medical devices T1 and T2 to be cleaned increases.

  According to the invention of claim 5, both end portions 3a, 3b of the tubular sheet 3 are folded outward so as to cover the annular grooves 11a, 11b on the outer periphery of the mounting ring bodies 1, 2, and the O-ring 5 Is fitted in the annular grooves 11a and 11b, and the O-ring 5 is in close contact with the inner peripheries 6a and 7a of the fastening cylinders 6 and 7 that are externally fitted to the mounting ring bodies 1 and 2, respectively. The cylindrical sheet 3 can be easily replaced with a new one due to breakage or life, and the both ends 3a and 3b of the cylindrical sheet 3 are securely fixed to the mounting ring bodies 1 and 2, and the fixing is performed. There is an advantage that leakage of the cleaning liquid L to the outside is prevented by liquid-tight sealing at the portion.

  According to the tubular medical device cleaning method of the sixth aspect of the present invention, the device receiving members 8A and 8B are arranged below the cleaning holders H1 and H2, and are placed upright inside the unconstrained tubular sheet 3. Since the lower ends of the tubular medical instruments T1 and T2 are supported by the instrument receiving members 8A and 8B, the cleaning holders H1 and H2 are used as convenient receiving containers for the used tubular medical instruments T1 and T2. It can be used to sequentially insert the finished tubular medical devices T1 and T2. When the accumulated tubular medical devices T1 and T2 reach a certain number, the tubular sheet 3 is bundled and constrained and held tightly by switching to the restrained state, and one end of the tubular sheet 3 is held in this restrained holding posture. If the cleaning liquid L is supplied from the side so that one open end e1 of each tubular medical instrument T1, T2 is immersed in the liquid, the cleaning liquid L passes through the inside of each tubular medical instrument T1, T2 and the other open end Since it flows out from e2, the lumen | bore of each of these tubular medical devices T1 and T2 can be wash | cleaned reliably.

  According to the seventh aspect of the present invention, in the above-described cleaning method, the tubular medical device T1 bent into a U-shape is erected so that the bent portion c is higher than the intermediate portion 30 of the tubular sheet 3. Therefore, it is possible to avoid an increase in the gap between the bent portions c located in the intermediate portion 30 of the tubular sheet 3 and to improve the cleanability of the lumens of the tubular medical devices T1 and T2.

The restraint state of the tubular medical device by the holder for washing is illustrated, (a) is a longitudinal side view, (b) is a plan view. It is a vertical side view which shows the washing | cleaning method by the washing | cleaning liquid supply from the upper direction in the holder for the washing | cleaning. It is a vertical side view which shows the washing | cleaning method by the washing | cleaning liquid supply from the downward direction in the same holder for washing | cleaning. It is a half vertical side view which illustrates the acceptance state of the tubular medical device by the holder for washing | cleaning of 2nd embodiment which concerns on this invention. It is a semi-longitudinal sectional side view which illustrates the washing state by the washing holder. It is a bar graph which shows the amount of residual protein of the suction tub tube cleaned by the method of this invention and the normal immersion method, and an unwashed suction tub tube. It is a bar graph which shows the amount of residual proteins for each suction scissor tube washed by the method of the present invention and the normal dipping method.

  The cleaning holder H1 of the first embodiment shown in FIGS. 1 and 2 is the most basic form of the cleaning holder of the present invention, and includes a pair of upper and lower mounting ring bodies 1, 2 made of a hard synthetic resin molded product. And a rubber cylindrical sheet 3 disposed on the inside thereof. Both the mounting ring bodies 1 and 2 have a short cylindrical shape with the same inner and outer diameters in the main portion, and the reduced diameter outer peripheral portion 2a at the upper portion of the lower mounting ring body 2 is added to the enlarged inner peripheral portion 1a of the upper mounting ring body 1. Is inserted so as to be relatively rotatable on the same axis. The cylindrical sheet 3 is folded outward so that the opened upper end side 3a wraps the upper edge of the upper mounting ring body 1 and the opened lower end side 3b wraps the lower edge of the lower mounting ring body 2 respectively. Then, the fastening band 9 is wound around and tightened from the outside to be fastened to the both mounting ring bodies 1 and 2 over the entire circumference.

  For example, as shown in FIG. 1 (a), such a cleaning holder H1 has a flange portion provided on the lower outer periphery of the lower mounting ring body 2 at the upper peripheral edge of a circular container-like instrument receiving member 8A disposed below. By placing 2b, the whole is made into a bottomed vertical cylindrical form and used as a receiving container for a used tubular medical device. That is, the curved tubular medical device T1, the straight tubular medical device T2, and the like subjected to surgery, treatment, examination, etc. are sequentially placed in the cleaning holder H1 so that the lower end thereof is supported by the device receiving member 8A. Stand inside.

  Then, when the tubular medical devices T1 and T2 stored in the cleaning holder H1 reach a certain number, the two attachment ring bodies 1 and 2 are relatively rotated as a pre-operation for cleaning. As shown in FIGS. 2 (a) and 2 (b), the tubular sheet 3 is twisted and deformed so that the intermediate portion 30 is narrowed by this rotation operation. Are bundled naturally, and are bound and held in a tight bundle inside the intermediate portion 30. The tubular medical devices T1 and T2 thus restrained and held can be simultaneously cleaned at the same time by supplying the cleaning liquid from above or below in the restraint and holding posture.

  First, in the method of supplying the cleaning liquid from above, as shown in FIG. 3, a liquid storage cylinder frame 4 </ b> A constituting an annular peripheral wall 41 higher than the upper edge of the cylindrical sheet 3 on the upper side of the cleaning holder H <b> 1. Is attached to the upper mounting ring body 1 in a liquid-tight manner, and a reed-type instrument receiving member 8B is disposed on the lower side. Then, when a cleaning liquid jet tube (not shown) is connected to the top opening 40 of the liquid storage cylinder frame 4A and the cleaning liquid L is introduced, the tubular medical that is tightly restrained and held inside the intermediate portion 30 of the cylindrical sheet 3. Since the gap between the instruments T1 and T2 is very small and the amount of liquid flowing down through the gap is very limited, a liquid pool L1 is generated and expanded in the liquid pool frame 4A. However, when the rising liquid level exceeds the upper end opening e1 of the tubular medical devices T1 and T2, the cleaning liquid L flows down through the inside of the tubular medical devices T1 and T2, and receives the device from the lower end opening e2. It passes through the porous bottom wall 81 of the member 8B and is discharged downward. Therefore, most of the supplied cleaning liquid L passes through the inside of the tubular medical devices T1 and T2 and is led out to the upper and lower sides, so that the lumens of the tubular medical devices T1 and T2 are surely cleaned. . Further, the arrangement of the instrument receiving member 8B prevents the downward movement of the tubular medical instruments T1 and T2 due to the pressure of the cleaning liquid L.

  In FIG. 3, the entire cleaning holder H1 is disposed vertically, but the cleaning holder H1 may be disposed in an inclined state in which the top opening 40 is high. In the case of this inclined arrangement, among the tubular medical devices T1 and T2 bundled at the initial stage of washing, a part of the upper end opening e1 that is higher in the inclined state is located in the air layer in the liquid storage tubular frame 4A. However, since the flow resistance in the tube is smaller than that in the cleaning liquid, the air in the liquid storage cylinder 4A is discharged through the tubular medical devices T1 and T2 in which the upper end opening e1 is located in the air layer. Along with this, the air layer shrinks and eventually the upper end openings e1 of all the tubular medical devices T1, T2 are immersed in the cleaning liquid L, and normal lumen cleaning can be performed.

  On the other hand, in the method of supplying the cleaning liquid from below, as shown in FIG. 4, a liquid storage tubular frame 4 </ b> A similar to the above is externally fitted on the upper mounting ring body 1 on the upper side of the cleaning holder H <b> 1. The liquid tank 10 is disposed on the lower side while being mounted. Then, the cleaning liquid L is introduced into the liquid tank 10 from the introduction port 10a, and the liquid layer L2 is sucked into the top opening 40 of the liquid storage tubular frame 4A with the lower end openings e2 of the tubular medical devices T1 and T2 immersed therein. When a tube (not shown) is connected and vacuum suctioned, the gap between the tubular medical devices T1 and T2 that are tightly restrained and held inside the intermediate portion 30 of the tubular sheet 3 is very small. Since the pressure loss due to the liquid is small, the cleaning liquid L in the liquid tank 10 passes through the tubular medical devices T1 and T2 and is sucked into the liquid storage cylinder frame 4A and fills the liquid storage cylinder frame 4A. It is discharged upward from the top opening 40, so that the lumen of each tubular medical device T1, T2 is reliably washed.

  Further, as a method of supplying the cleaning liquid from below, there is a method of performing lumen cleaning by supplying the cleaning liquid L from below without performing vacuum suction from above. In this case, the cleaning liquid L may be supplied at a pressure higher than a predetermined pressure from the inlet 10a in a state in which the space between the lower mounting ring body 2 of the cleaning holder H1 and the liquid tank 10 is sealed. The cleaning liquid L is discharged from the top opening e1 into the liquid storage cylinder frame 4A through the tubular medical devices T1 and T2, and is discharged upward from the top opening 40 while filling the liquid storage cylinder frame 4A. Is done.

  The cleaning liquid L here includes a decontamination cleaning liquid containing a chemical component such as a surfactant, a proteolytic enzyme, and a bactericide, and water for decontamination (usually tap water). And in the water washing with a tap water, what is necessary is just to connect the hose connected to a water tap as a washing | cleaning liquid jet pipe to the top opening 40 of 4 A of liquid storage cylinder frames. In addition, about washing | cleaning of the outer surface side of tubular medical instrument T1, T2, before or after washing | cleaning of the lumen | bore in the constrained state of the cylindrical sheet 3 mentioned above, the jet of the cleaning liquid L is performed in the unconstrained state of the tubular sheet 3 You can make it soak.

  The cleaning holder H2 of the second embodiment shown in FIGS. 5 and 6 is improved in terms of operability and cleaning performance with respect to the first embodiment, but is common to the first embodiment. Are denoted by the same reference numerals and description thereof is omitted.

  In the cleaning holder H2, as in the first embodiment, a rubber cylindrical sheet 3 having both ends open is provided on the inner side of the upper and lower mounting rings 1 and 2 arranged coaxially. It is arranged. However, annular grooves 11a and 11b are provided on the outer peripheral upper edge of the upper mounting ring body 1 and the outer peripheral lower edge of the lower mounting ring body 2, respectively, and the upper edge 3a and lower end 3b of the tubular sheet 3 are provided. Is folded outward so as to cover the annular grooves 11a and 11b, and the O-ring 5 is fitted into the annular grooves 11a and 11b from above, so that the upper and lower ends 3a and 3b of the tubular sheet 3 are It is fixed to both mounting ring bodies 1 and 2 over the entire circumference.

  Further, male threaded portions 12a and 12b are formed at the outer peripheral intermediate portions of the both mounting ring bodies 1 and 2, and upper and lower fastening cylinders 6 and 7 having female threaded portions 13a and 13b on the inner peripheries are respectively mounted ring bodies 1. , 2 and the inner peripheries 6a, 7a of the fastening cylinders 6, 7 are in close contact with the O-ring 5, so that the mounting ring bodies 1, 2 and the fastening cylinders 6, 7 are connected to each other. Is hermetically sealed and the O-ring 5 is prevented from coming off, so that the upper and lower end portions 3a, 3b of the cylindrical sheet 3 are firmly attached. Thus, the upper fastening cylinder 6 is integrally formed with a liquid storage cylinder frame 4B that forms an annular peripheral wall portion 42 that expands from the entire circumference of the upper part to the outside.

  Further, an outer cylindrical body 14 that covers the outer periphery extending from a position closer to the lower portion of the upper mounting ring body 1 to a position closer to the upper portion of the lower mounting ring body 2 is fitted to the middle portion of the cleaning holder H2 in a circumferentially rotatable manner. An O-ring 15 fitted on each of the mounting ring bodies 1 and 2 is interposed between the inner periphery of the outer cylindrical body 14 and the outer periphery of both the mounting ring bodies 1 and 2. The outer cylinder body 14 has an upper end 14 a in contact with the downward annular step 16 integrally formed on the outer periphery of the upper mounting ring body 1, and a lower end 14 b in contact with the upper end 7 b of the lower fastening cylinder 7. In addition, groove-shaped notches 17 that are recessed upward from the lower end 14b are formed at a plurality of circumferential locations (four locations in the figure) on the lower edge of the outer cylindrical body 14, and are formed on the lower mounting ring body 2 side. The fixed rotation stopper pin 18 is fitted in each notch portion 17. The lower mounting ring body 2 and the outer cylinder body 14 are held so as not to rotate relative to each other by the fitting of the non-rotating pin 18 to the notch portion 17, and the lower mounting ring body 2 moves up and down within the range of the notch portion 17. It is possible.

  Therefore, in the cleaning holder H2, as shown in FIG. 5, the lower mounting ring body 2 is in the upper limit position where the upper end abuts the lower end of the upper mounting ring body 1 in the unconstrained state of the cylindrical sheet 3. Is set. However, when the lower fastening cylinder 7 is rotated from this state in a direction to deepen the screwing with respect to the lower mounting ring body 2, the contact state between the fastening cylinder 7, the outer cylindrical body 14 and the upper mounting ring body 1 is changed. Since the outer cylinder body 14 and the lower mounting ring body 2 are not rotatable relative to each other, only the lower mounting ring body 2 is lowered and separated from the upper mounting ring body 1, and the cylindrical sheet is separated by the distance. 3 extends in the vertical direction.

  Similar to the first embodiment, such a cleaning holder H2 is used as a receiving container for a used tubular medical device when the tubular sheet 3 is not restrained. In the illustrated example, the receiving container is configured by placing the cleaning holder H2 on the net cage 8B as the instrument receiving member via the annular receiving frame 19, and is used for surgery, treatment, inspection, and the like. The bent tubular medical device T1, the straight tubular medical device T2, and the like are sequentially placed on the inside of the cleaning holder H2 so that the lower ends thereof are supported by the mesh cage 8B.

  When the tubular medical instruments T1 and T2 stored in the cleaning holder H2 reach a certain number, the outer cylindrical body 14 is rotated to restrain the cylindrical sheet 3 as a pre-operation for cleaning. Convert to That is, as the outer cylindrical body 14 rotates, the lower mounting ring body 2 also rotates integrally through the engagement of the notch 17 and the locking pin 18, but the upper mounting ring body 1 does not rotate. As shown in the figure, the tubular sheet 3 is twisted and deformed so that the intermediate portion 30 is narrowed, so that the tubular medical devices T1 and T2 that have been erected are naturally bundled together inside the intermediate portion 30. It is held in a tight bundle.

  Thus, after the tubular medical devices T1 and T2 are constrained and held by the cleaning holder H2, the cover plate 20 is put on the liquid storage cylinder frame 4B as shown in FIG. The lid 20 is fixed by fitting a locking pin 43 protruding from the upper outer surface of the liquid storage cylinder frame 4B into the groove 20a, and the cleaning liquid jet tube is inserted into the connecting screw hole 20b in the center of the lid 20 21 injection ports 21a are screwed in. When the cleaning liquid L is introduced into the liquid storage cylinder frame 4B from the injection port 21a, the inner side of the intermediate portion 30 of the cylindrical sheet 3 is tightly constrained and held as in the case of the first embodiment. Since the gap between the tubular medical devices T1 and T2 is very small and the amount of liquid flowing down through the gap is very limited, a liquid reservoir L1 is generated and enlarged in the liquid storage cylinder frame 4B. Then, at the stage where the rising liquid level exceeds the upper end opening e1 of the tubular medical devices T1 and T2, the cleaning liquid L flows down through the inside of the tubular medical devices T1 and T2, and the net from the lower end opening e2 It passes through the porous bottom wall 81 of the ridge 8B and is discharged downward. Accordingly, most of the supplied cleaning liquid L passes through the tubular medical devices T1 and T2 and is led out to the other side in the vertical direction, and the lumens of the tubular medical devices T1 and T2 are reliably cleaned, The net cage 8B prevents the tubular medical instruments T1, T2 from moving downward due to the pressure of the cleaning liquid L.

  Further, in this cleaning holder H2, both end portions 3a, 3b of the cylindrical sheet 3 are folded outward so as to cover the outer circumferential grooves 11a, 11b of the mounting ring bodies 1, 2, and an O-ring 5 is formed from above. Is fitted in the annular grooves 11a and 11b, and the O-ring 5 is in close contact with the inner peripheries 6a and 7a of the fastening cylinders 6 and 7 that are externally fitted to the mounting ring bodies 1 and 2, respectively. It can be easily replaced with a new one due to breakage or life, and both ends 3a and 3b of the cylindrical sheet 3 are securely fixed to the mounting ring bodies 1 and 2, and the liquid sealing is performed at the fixed portions. By stopping, there is an advantage that leakage of the cleaning liquid L to the outside is prevented.

  In the illustrated example of FIG. 6, the two attachment ring bodies 1 and 2 are separated in the vertical direction in order to increase the tightening force by the intermediate portion 30 of the cylindrical sheet 3. This is because the cylindrical sheet 3 is stretched in advance by rotating the lower fastening cylinder 7 in the state. That is, when the unconstrained tubular sheet 3 is stretched in advance as described above, the elastic restoring force when converted to the restrained state is increased and the tightening force is increased, and the middle of restraining the bundle of the tubular medical devices T1 and T2 Since the vertical width of the portion 30 is also enlarged, the tubular medical devices T1 and T2 can be more strongly restrained and held. Therefore, the tightening force necessary for restraint changes depending on the number of restraints of the tubular medical devices T1 and T2, and therefore, the degree of expansion and contraction of the tubular sheet 3 may be adjusted appropriately according to the restraint number.

  In the cleaning holder H2 of the second embodiment, as in the first embodiment, the cleaning holder H2 at the time of cleaning may be disposed in an inclined manner in the method of supplying the cleaning liquid L from below. It is also possible to adopt a method of supplying from below. However, since many tubular medical devices are generally narrower on the distal end side than on the proximal end side (operation side), when the cleaning liquid L is supplied from below in a normal standing posture with the distal end side down, the cleaning liquid L Enters the lumen from the side with the smaller diameter, depressurizes by expanding the flow path, flows out from the side with the larger diameter, and weakens the cleaning power of the lumen. Therefore, when the tubular medical device whose upper end side is large in the standing state is to be cleaned, including the case of the first embodiment, a method of supplying the cleaning liquid L from above is recommended.

  In addition to supplying the cleaning liquid L to the cleaning holder through a tube or pipe from a cleaning liquid tank with a discharge pump, the cleaning liquid L in an existing medical instrument cleaning apparatus such as a tubular cleaning device or a washer disinfector is used. A method that is performed by connecting to a jet port or a spray nozzle port, a method that is performed by connecting to a jet port of a liquid circulation type thermostatic bath containing a cleaning liquid, and the like can also be employed.

  As a tubular medical device to which the present invention is applied, the curved and straight tubular medical devices T1 and T2 are shown in a simple pipe form in order to make the operation easy to understand, but the end shape, the diameter, There are a wide variety of items with different degrees of bending and length. Specific examples include various suction tubes used in otolaryngology and neurosurgery, fistulas of powder and spray injectors, cleaning fistulas used in ophthalmology and oral surgery, catheters, and surgical instruments. And some medical tubes such as silicon tubes and respiratory snake tubes.

  Thus, according to the present invention, as suggested from the above-described first and second embodiments, the tubular medical device can be used regardless of the number of tubes placed on the inside of the tubular sheet 3. By simply switching the sheet 3 from the unconstrained state to the restrained state, the central sheet 30 is tightly bundled and restrained and held, so even a large number of dozens of sheets can be washed at the same time without any trouble, and high in simple operation. In addition to high processing efficiency, different types can be cleaned at once. In addition, the difference in the type of the tubular medical device includes not only the difference in the end shape and the diameter, but also the difference in the outer diameter, the presence / absence of the bend, the position and degree of the bend, the slight difference in length, and the like. In addition, the cleaning holder of the present invention is structurally extremely simple and can be manufactured at low cost, and an adapter corresponding to the type of tubular medical instrument as in the past is unnecessary, so that the cleaning holder can be used as a cleaning device. The equipment cost and the material cost can be greatly reduced as compared with the prior art.

  In the method for cleaning a tubular medical device according to the present invention, when a bent medical device such as a curved tubular medical device T1 exemplified as an object to be cleaned is included, the bent portion c is an intermediate portion of the tubular sheet 3. It is better to stand so as to be higher than the unit 30. This is because, when the bent portion c is positioned at the intermediate portion 30 of the tubular sheet 3, the clearance between the tubular medical devices when restrained and held tends to increase, and thereby the cleaning liquid that passes through the lumen of the tubular medical device This is because the ratio of L is reduced and the cleaning property is lowered.

  In the illustrated cleaning holders H1 and H2 of the first and second embodiments, when the upper and lower mounting ring bodies 1 and 2 are relatively rotated to bring the cylindrical sheet 3 into a restrained state, the rubber of the cylindrical sheet 3 Both mounting ring bodies 1 and 2 are placed in a fixed state by elastic restoring force, but in the present invention, both a locking mechanism for fixing both mounting ring bodies 1 and 2 in the restrained state, and both in the restrained state. An uneven engagement portion for making the attachment ring bodies 1 and 2 difficult to relatively rotate may be provided. Further, in the second embodiment, the upper and lower mounting ring bodies 1, 2 are separated and displaced in the axial direction by the threaded portion between the lower mounting ring body 2 and the lower fastening cylinder 7. However, as this connecting / disconnecting means, the direct fitting part of the both mounting ring bodies 1 and 2 in the first embodiment is a screwed structure, or an engaging structure of an inclined guide groove and a pin is used instead of the screw part. Also good. In addition, the detailed configuration of the cleaning holder of the present invention can be variously modified in addition to the embodiment.

[Cleaning test]
15 suction fistula tubes (four types of suction pipes color-coded for each diameter manufactured by Daiichi Medical Co., Ltd .: four yellow (outer diameter 2.3 mm), four green (outer diameter 2.6 mm), After passing 1 ml of 10% human serum through each of three red (outer diameter 2.9 mm) and blue (outer diameter 3.4 mm)], it was dried at room temperature for 12 hours, and further at 120 ° C. for 1 hour. Samples were heat-denatured by heat drying. Then, in a liquid circulation thermostatic chamber (incubator CCS-099 manufactured by Clean Chemical Co., Ltd., container CCS-001), a cleaning liquid (protease-containing neutral detergent manufactured by Clean Chemical Co., Ltd .: 1% dilution of trade name S CLEAN EM) ), And kept at a temperature of 40 ° C., the 15 suction tubules of the sample are in close contact with the cleaning holder H2 of the second embodiment (inner diameter 64 mm, length 92 mm when the cylindrical sheet 3 is attached). And the nozzle 21a of the jet pipe 21 of the thermostatic bath is connected to the screw hole 20b for connection of the lid plate 20 of the cleaning holder H2 (see FIG. 6), and cleaning is performed for 60 minutes. Rinse thoroughly under running water. In addition, as a normal immersion cleaning, 15 suction scissors tubes of the same sample were immersed in the thermostatic bath cleaning solution for 60 minutes and then rinsed in the same manner.

[Cleanability evaluation 1]
The above-described cleaning test using the cleaning holder of the present invention and the cleaning test using the normal immersion cleaning are each performed three times, and the detection kit (acidic dye) disclosed in Japanese Patent No. 3165668 is used for each suction fistula after the test. The amount of residual protein was quantified according to the detection method of protein adhering substance using amide black 10B as The result is shown in FIG. Moreover, the average value of the residual protein mass by the washing | cleaning test by the holder for washing | cleaning of this invention and a normal immersion cleaning is shown in FIG. 8 with the average value of the residual (adhesion) protein mass in the case of an unprocessed (blank).

  From the results of FIG. 7 and FIG. 8, when a large number of tubular medical devices are to be cleaned, and the proteins attached to the lumens are simultaneously cleaned and removed, according to the cleaning using the cleaning holder of the present invention, It can be seen that a much higher cleaning removal effect can be obtained as compared with ordinary immersion cleaning. Further, from FIG. 7, it is clear that the use of the cleaning holder of the present invention has a very small difference in cleaning and removing action due to the difference in tubular medical instruments, and high reliability can be obtained.
