Description

  The present invention relates to a medical tube seal apparatus.

  Conventionally, a plurality of tube seal portions are linearly arranged as a medical tube seal device that seals and welds a medical tube (hereinafter simply abbreviated as “tube”) disposed between a pair of electrodes. A medical tube seal device is known (for example, see Patent Document 1). In the case where, for example, eight tube seal portions are provided, a total of eight locations can be sealed and welded almost simultaneously by a single sealing operation.

  Each of the plurality of tube seal portions is provided with one detection portion on each side of the pair of electrodes for detecting that a medical tube has been inserted between the pair of electrodes.

  In this specification, “both sides of a pair of electrodes” means the positions on the right side and the left side of the pair of electrodes when the pair of electrodes are viewed along the opposing direction of the pair of electrodes. That means.

  By the way, a tube connected to a blood bag or the like is stored in a folded state before use (at a stage where it is wrapped in a packaging material). )). When such a tube with a crease or the like is inserted into a plurality of tube seal portions, the detector may not detect the insertion of the tube at a portion with a crease or the like. In that case, in the conventional medical tube seal device, if the detection unit does not detect the insertion of the tube even at one place, the plurality of tube seal units are controlled so as not to perform the sealing operation as a whole. Even if it is visible to the user of the apparatus (hereinafter simply referred to as the user) as if the tube is inserted in the entire tube seal portion, there may be a case where the sealing operation is not started at all.

  In addition, when a user who is suspicious that the sealing operation is not started at one time tries to remove the tube from a plurality of tube seal portions, for example, the tube is detected by chance in the detection portion that has not detected the tube insertion. There are cases where this would occur. In that case, since the entire sealing operation is performed at an unintended timing, the tube may break due to the overlap of the sealing operation and the operation of removing the tube, or insufficient sealing may occur in a part of the tube. This may cause a sealing failure.

  Therefore, the present invention has been made to solve such a problem, and can prevent seal welding at a timing not intended by the user, and can suppress the occurrence of a seal failure. An object is to provide a medical tube seal device.

  In order to achieve the above-described object, the inventor of the present invention, when a tube with a crease or the like is inserted into a tube seal portion, the detection portion (on both sides of the tube and a pair of electrodes) The positional relationship with the two detection units) was thoroughly investigated. As a result, when a tube with a crease or the like is inserted into the tube seal portion, even if the tube is located at a position where the detection portion is not detected by one of the two detection portions (a non-detectable position), the other In the detection part, the knowledge that the tube is located at a detectable position was obtained. That is, when a tube with creases or the like is inserted into the tube seal part, the tube is not located at a position where both of the two detection parts are not detected, but at one of the detection parts, the tube is located at a detectable position. It is located.

  The inventor of the present invention, based on the above knowledge, in the medical tube seal device in which one detection part is disposed on each side of the pair of electrodes, either one of the detection parts detected insertion of the tube. Based on the above, the inventors have conceived that the above-described problems can be solved if the entire tube seal portion is configured to perform the sealing operation, and the present invention has been completed.

  That is, the medical tube seal device of the present invention comprises a device main body, a plurality of tube seal portions provided in the device main body and arranged in a straight line, and a main control unit that performs overall control of each part of the device, Each of the plurality of tube seal portions is a pair of electrodes arranged orthogonal to the arrangement direction of the plurality of tube seal portions, and detection for detecting that a medical tube is inserted between the pair of electrodes.

The tube seal portion to be arranged is referred to as a “tube seal portion belonging to the second group”, and the tube arranged between the “tube seal portion belonging to the first group” and the “tube seal portion belonging to the second group”. The seal portion is referred to as “tube seal portion belonging to the third group”.
When the medical tube seal device 1 is viewed from the front, the tube seal portion 20A arranged on the rightmost side is a tube seal portion belonging to the first group, and the tube seal portion 20H arranged on the leftmost side is the first tube seal portion. It is a tube seal part which belongs to 2nd group, and tube seal parts 20B-20G are tube seal parts which belong to the 3rd group.

  The apparatus main body 10 is provided with a slot portion into which an external memory (for example, an SD card or a compact flash (registered trademark)), for example, as an external recording medium can be inserted.

  The tube seal portions 20A to 20H are high-frequency tube sealers that have a function of closing (sealing) a tube at a high frequency, for example. The structure of the tube seal portion 20A to 20H will be described by taking the tube seal portion 20A as an example. As shown in FIGS. 1 to 6, the tube seal portion 20A includes a pair of electrodes 21A and 22A and a pair of electrodes. Two detections for detecting that the tube has been inserted between the pair of electrodes 21A and 22A, the electrode support portions 23A and 24A for supporting 21A and 22A, the cover member 25A for covering the pair of electrodes 21A and 22A Parts 30A and 35A, and an advance / retreat mechanism 40A connected to the electrode support 23A.

  Of the pair of electrodes 21A and 22A, the electrode 21A is a movable electrode, and the electrode 22A is a fixed electrode. The pair of electrodes 21A and 22A is arranged orthogonal to the arrangement direction of the tube seal portions 20A to 20H (left and right direction when the apparatus main body 10 is viewed from the front). The pair of electrodes 21A and 22A is provided so as to protrude from the front surface of the apparatus main body 10, and is covered with a cover member 25A. As can be seen from FIG. 4, the cover member 25A is provided so that a tube can be inserted between the pair of electrodes 21A and 22A from above.

  The detection units 30A and 35A are arranged one on each side of the pair of electrodes 21A and 22A along the arrangement direction of the tube seal portions 20A to 20H (left and right direction when the apparatus main body 10 is viewed from the front). . As shown in FIG. 6A, the detectors 30A and 35A include light emitting elements 31A and 36A disposed on both sides of the electrode 21A, and light receiving elements 32A and 37A disposed on both sides of the electrode 22A. The light emitting elements 31A and 36A and the light receiving elements 32A and 37A are arranged at positions facing each other. The detection units 30A and 35A are, for example, transmissive photo interrupters, and as shown in FIG. 6B, the light from the light emitting elements 31A and 36A is blocked by the tube T inserted between the pair of electrodes 21A and 22A. The light receiving elements 32 </ b> A and 37 </ b> A detect that this has been done, and send the detection information to the main control unit 70.

  The advance / retreat mechanism 40A is composed of, for example, an electric cylinder. When the linear motion by the advance / retreat mechanism 40A is transmitted to the electrode 21A via the electrode support portion 23A, the electrode 21A is moved along the direction in which the pair of electrodes 21A and 22A approach or separate from each other. .

  The other tube seal portions 20B to 20H basically have the same configuration as the tube seal portion 20A described above.

  The lighting units 50A to 50H are made of LEDs, for example, and configured to emit light or blink in a plurality of colors.

  The power supply unit 60 guides AC power from an external commercial power supply or the like through a power cable (not shown), and performs processing such as transformation, rectification, and smoothing by a built-in AC / DC conversion unit (not shown). And has a function of supplying power to each part of the medical tube seal device 1.

  In the storage unit 62, it is determined that a tube is inserted into the tube seal portions 20A and 20H belonging to the first group and the second group, and then it is determined that a tube is inserted into the tube seal portions 20B to 20G belonging to the third group. At least data relating to a standard time until the process is performed (corresponding to a “predetermined time” described in the claims and hereinafter referred to as a standard time) is stored.

  The data related to the standard time stored in the storage unit 62 is configured to be rewritable by, for example, a user operation.

  The main control unit 70 is composed of, for example, a microcomputer. As shown in FIG. 1, the main control unit 70 includes a tube insertion state determination unit 72, a seal operation control unit 74 that controls the seal operation of the tube seal units 20A to 20H, and tubes belonging to the first group and the second group. The time (hereinafter referred to as elapsed time) from when it is determined that a tube has been inserted into the seal portions 20A and 20H until it is determined that the tube has been inserted into all of the tube seal portions 20B to 20G belonging to the third group. It has at least an elapsed time measuring unit 76 that measures and a lighting operation control unit 78 that controls the lighting operation of the lighting units 50A to 50H.

  In each of the tube seal portions 20A to 20H, the tube insertion state determination portion 72 has a function (first function) for determining whether or not a tube has been inserted between the pair of electrodes, and the tube seal portions 20A to 20H. When either one of the two detectors detects the insertion of the tube, it has a function (second function) for determining that the tube has been inserted into the tube seal portion.

  The second function of the tube insertion state determination unit 72 will be further described. In the tube seal unit 20A belonging to the first group, the detection unit 30A disposed on the front right side of the two detection units 30A and 35A inserts the tube. When detected, it is determined that “a tube has been inserted into the tube seal portion 20A”. In the tube seal portion 20H belonging to the second group, when the detection portion 35H arranged on the front left side of the two detection portions 30H and 35H detects the insertion of the tube, “the tube is inserted into the tube seal portion 20H. It is determined. In each of the tube seal portions 20B to 20G belonging to the third group, when any one of the two detection portions 30B to 30G and 35B to 35G detects the insertion of the tube, “the tube seal portion has a tube. It is determined that it has been inserted.

  For example, when the tube T is inserted into the tube seal portions 20A to 20H as shown in FIG. 7B, the detection portion 30A detects the insertion of the tube T in the tube seal portion 20A belonging to the first group. Therefore, the tube insertion state determination unit 72 determines that “the tube T has been inserted into the tube seal portion 20A”. In the tube seal part 20H belonging to the second group, since the detection part 35H detects the insertion of the tube T, the tube insertion state determination part 72 states that “the tube T has been inserted into the tube seal part 20H”. judge. In each of the tube seal portions 20B to 20G belonging to the third group, since either one of the two detection portions detects the insertion of the tube T, the tube insertion state determination portion 72 indicates that “the tube seal portion 20B It is determined that the tube T is inserted into each of ˜20G ”. At the position of the tube seal portion 20C, since the tube T has a crease or the like, the insertion of the tube T is not detected at the position of the detection portion 35C located on the left side, but the detection located on the right side. The insertion of the tube T is detected at the position of the part 30C.

  The seal operation control unit 74 performs the seal operation when it is determined that the tube is inserted between the pair of electrodes in all of the tube seal units 20A to 20H based on the determination result by the tube insertion state determination unit 72. When the elapsed time measured by the function for controlling the tube seal portions 20A to 20H (sealing operation control function) and the elapsed time measurement portion 76 exceeds the standard time, all of the tube seal portions 20A to 20H It has a function (lock function) for controlling the tube seal portions 20A to 20H so as not to perform the sealing operation.

  The lock function of the seal operation control unit 74 will be further described. The seal operation control unit 74 reads data related to the standard time stored in the storage unit 62, and the elapsed time measured by the elapsed time measurement unit 76 and the standard. Compare time. When the elapsed time exceeds the standard time, the tube seal portions 20A to 20H are controlled so that the sealing operation is not performed in all the tube seal portions 20A to 20H. When the above-described locking function works, even when trying to remove the tube T from the tube seal portions 20A to 20H, the sealing operation is not performed at a timing not intended by the user.

  As the case where the elapsed time exceeds the standard time, for example, after it is determined that the tube is inserted into the tube seal portions 20A and 20H belonging to the first group and the second group, the tube seal portions 20B to 20B belonging to the third group There is a case where it is not determined that a tube is inserted in at least one tube seal portion of 20G, and as a result, a standard time has elapsed.

  When the elapsed time measured by the elapsed time measurement unit 76 exceeds the standard time stored in the storage unit 62, that is, the lighting operation control unit 78 as a notification unit, that is, the tube function is controlled by the lock function of the seal operation control unit 74. When the sealing operation is not performed in all of the sealing portions 20A to 20H, a function (lock state notification function) of causing at least one of the lighting portions 50A to 50E to blink is provided.

  The lock state notification function will be specifically described. For example, when the tube T is inserted into the tube seal portions 20A to 20H as shown in FIG. 7C, the tube T is positioned at the position of the tube seal portion 20E. Since it is not inserted properly, the two detection parts 30E and 35E of the tube seal part 20E do not detect the insertion of the tube T. In this case, by the second function of the tube insertion state determination unit 72, “the tube T is inserted in the tube seal portions 20A to 20D and 20F to 20H, and the tube T is not inserted in the tube seal portion 20E”. It is determined. If the tube seal portion 20E belonging to the third group continues to be in a state where it is not determined that “the tube T has been inserted”, the elapsed time measured by the elapsed time measurement portion 76 exceeds the standard time, and as a result, the seal operation control portion The lock function 74 is exhibited, and the sealing operation is not performed in all the tube seal portions 20A to 20H. At this time, the above-described lock state notification function of the lighting operation control unit 78 is exhibited, and the lighting unit 50E corresponding to the tube seal unit 20E determined that the tube is not inserted among the lighting units 50A to 50H blinks. . By this blinking operation, the user can clearly recognize that the sealing operation is not performed in all of the tube seal portions 20A to 20H. Moreover, it is used that there was some trouble in the insertion state of the tube T at the position of the tube seal part 20E among the tube seal parts 20A to 20H by the lighting part 50E blinking among the lighting parts 50A to 50H. Will be able to recognize.

  In the example shown in FIG. 7C, the tube T is slightly shifted so as not to be removed from the tube seal portions 20A to 20H before the elapsed time measured by the elapsed time measurement unit 76 exceeds the standard time. If it is determined that “tube T is inserted” in all the tube seal portions 20A to 20H including the tube seal portion 20E belonging to the third group, the lock function of the seal operation control portion 74 is exhibited. Absent.
