The first positioning hole 411 and the second positioning hole 412 are latching recesses for fitting and latching the fitting protrusions 571 of the attachment / detachment operation member 504 shown in FIG. The fitting protrusion 571 is a so-called dog that is fitted into the first positioning hole 411 or the second positioning hole 412 and latched.

Next, the structure of the support member mounting unit 500 will be described with reference to FIGS.
6 is a perspective view showing the back surface portion 2R on which the support member mounting unit 500 is mounted, and FIG. 7 is a perspective view showing the back side of the support member mounting unit 500. As shown in FIG. FIG. 8 is a view showing the back surface portion 2R to which the support member mounting unit 500 is mounted.
As shown in FIG. 6, the support member mounting unit 500 can be called a pole clamp, for example, and is detachably held (clamp) with respect to a stand pole 900 as a support member for supporting the infusion pump 1. It is a mounting tool to do. The support member mounting unit 500 has a back surface portion with respect to the first engaging portion 401, the second engaging portion 402, the third engaging portion 403, and the fourth engaging portion 404 of the mounting portion 400 shown in FIG. By sliding and fitting along 2R along the Z2 direction, the back surface 2R is detachably mounted and engaged.

The support member mounting unit 500 shown in FIG. 6 includes, for example, a plastic base 501, a metal fixing portion 590 such as aluminum mounted on the base 501, and an attachment / detachment operation member 504. Yes. Thereby, weight reduction and cost reduction can be achieved by making the base 501 made of plastic instead of metal. However, the fixing portion 590 is made of a metal such as aluminum, for example, to ensure strength when the pole 900 is clamped.
6 and 8, the base 501 is mounted and engaged with the back surface portion 2R in the first mounting posture RS1, and in FIG. 10, the base 501 is different from the first mounting posture RS1 in a second state. It is mounted on the back surface portion 2R in the mounting posture RS2. As shown in FIG. 8, in the base 501 in the first mounting posture RS1, the fixing unit 590 can be fixed by detachably holding a pole 900 as a support member arranged along the first direction (Z direction). It is. On the other hand, as shown in FIG. 10, the fixing portion 590 is arranged along the second direction (X direction) different from the first direction (Z direction) in the base 501 of the second mounting posture RS2. A pole 900 as a support member can be detachably sandwiched and fixed. The first mounting posture RS1 and the second mounting posture RS are in a position rotated 90 degrees with respect to each other. Thus, since the base 501 can be attached to the back surface portion 2R in two mounting postures, the first mounting posture RS1 and the second mounting posture RS2, the poles arranged in the Z direction shown in FIG. 900 can be fixed, and the pole 900 arranged in the X direction shown in FIG. 10 can also be fixed.

As shown in FIG. 7, the base 501 has a main body 521, for example, a square plate-shaped attachment portion 522. The main body 521 is fitted and fixed with a strength holding unit 502 shown in FIG. As shown in FIG. 7, the plate-like attachment portion 522 has attachment edge portions 522A, 522B, 522C, and 522D. The mounting edge portions 522A, 522B, 522C, and 522D are detachably fitted to the first engaging portion 401, the second engaging portion 402, the third engaging portion 403, and the fourth engaging portion 404 of the mounting portion 400. This is the part that can be installed. As shown in FIGS. 6 and 7, a protrusion-shaped stopper 540 is formed at the end of the attachment edge portion 522.
As shown in FIGS. 6 and 8, the fixing portion 590 includes a strength holding unit 502 and a pressing member 503. The strength holding unit 502 is formed in a substantially U shape, and has a first protrusion 502A and a second protrusion 502B. The first projecting portion 502A and the second projecting portion 502B face each other at an interval. This interval is set larger than the width of the pole 900. The cross-sectional shape of the pole 900 is not particularly limited, and may be circular or rectangular.

As shown in FIGS. 6 and 8, the pressing member 503 has a male screw portion 530, a rotation operation member 531, and a pusher 532, and the male screw portion 530 is a female screw portion 533 of the first projecting portion 502A. Biting against. The metal pusher 532 is fixed to the distal end portion of the external thread portion 530 and faces the second projecting portion 502B. The male screw portion 530 and the pusher 532 are made of metal in order to obtain mechanical strength when fixing the pole. However, the rotary operation member 531 is preferably made of plastic for weight reduction.
9A and 9B show examples of the shape of the pusher 532 and the second projecting portion 502B and a state where they are fixed to different poles 900 and 901, and are viewed from the Z1 direction in FIG. It is a figure.

The pusher 532 has concave portions 550 and 551 and inclined portions 552 and 553. Similarly, the 2nd protrusion part 502B has the recessed parts 560 and 561 and the inclination part 562,563. The concave portions 550 and 551 and the inclined portions 552 and 553 face the concave portions 560 and 561 and the inclined portions 562 and 563, respectively. When the operator rotates the rotation operation member 531 in the forward direction, the pusher 532 can be gradually advanced in the X1 direction with respect to the second protrusion 502B.
As a result, for example, as shown in FIG. 9A, a pole 900 having a circular cross section is sandwiched between the concave portions 550 and 551, the inclined portions 552 and 553, the concave portions 560 and 561, and the inclined portions 562 and 563. Thus, the infusion pump 1 can be detachably fixed to the pole 900 using the support member mounting unit 500. Further, as shown in FIG. 9B, the infusion pump 1 uses a support member mounting unit 500 by inserting a pole 901 having a rectangular cross section between the recesses 550 and 551 and the recesses 560 and 561. The pole 901 can be detachably fixed. Thus, the infusion pump 1 can be easily and reliably fixed to the pole 900 or 901 even if the cross-sectional shape and thickness of the pole are different.

  The attachment / detachment operation member 504 shown in FIGS. 6 and 7 is made in a tongue-like shape, for example, by an elastically deformable plastic, and has a knob portion 570 and a fitting projection 571. The fitting protrusion 571 is formed to protrude toward the back surface 572, and is, for example, a square protrusion. The fitting protrusion 571 that is a square protrusion is sized to fit into the square first positioning hole 411. For example, as shown in FIG. 8, the mounting unit 500 of the support member is in the first mounting posture RS1, and the first engaging portion 401, the second engaging portion 402, the third engaging portion 403, the fourth engaging portion 400 of the mounting portion 400. In a state where it is slid and attached to the engaging portion 404, the fitting protrusion 571 is fitted into the first positioning hole 411 on the back surface portion 2R side. Accordingly, the fitting protrusion 571 and the first positioning hole 411 constitute a retaining means for preventing the attachment unit 500 of the support member from falling out of the mounting portion 400 in the Z1 direction.

  As described above, in a state where the attachment unit 500 of the support member is prevented from being detached from the mounting portion 400, the stopper portion 540 is in contact with the lower side of the third engagement portion 403. Thus, the support member mounting unit 500 is prevented from entering the Z2 direction (upward) any more from the mounted state of FIG. As a result, the fitting protrusion 571 and the first positioning hole 411 can be aligned in the Z2 direction, so that the fitting protrusion 571 can be securely fitted into the first positioning hole 411.

By the way, in correct 1st mounting attitude | position RS1 of the attachment unit 500 of the supporting member shown in FIG. 8, the rotation operation member 531 is located in the left side in FIG. However, unlike this correct first mounting posture, if the rotation operation member 531 is not shown in FIG. 8 but is positioned on the right side and the support member mounting unit 500 is slid in the Z2 direction to be mounted, it will try to slide. Since the protruding stopper portion 540 hits the fourth engaging portion 404 before the mounting, the support member mounting unit 500 cannot be slid in the Z2 direction. That is, the protruding stopper portion 540 can prevent the mounting unit 500 of the support member from being mounted in the Z2 direction in an incorrect posture that is not the first mounting posture RS1.
In FIG. 8, by removing the fitting protrusion 571 from the first positioning hole 411, when the support member attachment unit 500 is removed from the attachment portion 400 in the Z <b> 1 direction and removed, the operator can remove the attachment / detachment operation member 504. It is only necessary to lift the knob portion 570 in the RQ direction. Thereby, the attachment unit 500 of a support member can be easily removed from the mounting part 400. In FIG. 8, by removing the fitting projection 571 and the first positioning hole 411 from the mounting portion 400 to remove the support member attachment unit 500 in the Z1 direction, the operator can remove the knob portion of the attachment / detachment operation member 504. It is only necessary to lift 570 in the RQ direction. Thereby, the attachment unit 500 of a support member can be easily removed from the mounting part 400.

  FIG. 10 shows a state in which the support member mounting unit 500 is mounted on the mounting portion 400 in the second mounting posture RS2 that is the second mounting direction. In the state of this second mounting posture RS2, the pole 900 is oriented in the horizontal direction, and compared with the first mounting posture RS1 shown in FIG. 8, the mounting posture of the support member mounting unit 500 with respect to the back surface portion 2R of the infusion pump 1 Is mounted in a state rotated 90 degrees to the right. The square fitting protrusion 571 is fitted into the square second positioning hole 412 on the back surface 2R side. As a result, the fitting protrusion 571 and the second positioning hole 412 constitute a retaining means for preventing the mounting unit 500 of the support member from falling out of the mounting portion 400 in the Z1 direction. In this state, the stopper portion 540 is in contact with the lower side of the fourth engaging portion 404 instead of the third engaging portion 403. Since the support member mounting unit 500 does not enter the Z2 direction any more from the mounted state of FIG. 10, the fitting projection 571 and the second positioning hole 412 can be easily aligned in the Z2 direction. The fitting protrusion 571 can be securely fitted into the second positioning hole 412.

By the way, in correct 2nd mounting attitude | position RS2 of the attachment unit 500 of the supporting member shown in FIG. 10, the rotation operation member 531 is located on the upper side. However, unlike this correct second mounting posture RS2, even if the support member mounting unit 500 is slid in the Z2 direction so that the rotation operation member 531 is positioned on the lower side, the protrusion is formed before the slide. Since the stopper portion 540 having a shape abuts against the third engagement portion 403, the attachment unit 500 of the support member cannot be slid and attached in the Z2 direction. That is, the protruding stopper portion 540 can prevent the mounting unit 500 of the support member from being mounted in the reverse direction with an incorrect mounting posture.
In FIG. 10, when the fitting protrusion 571 is removed from the second positioning hole 412 and the support member attachment unit 500 is removed from the attachment portion 400 in the Z1 direction and removed, the operator removes the knob of the attachment / detachment operation member 504. It is only necessary to lift the portion 570 in the RQ direction. Thereby, the attachment unit 500 of a support member can be easily removed from the mounting part 400.

In addition, the support member mounting unit 500 is mounted to the mounting portion 400 of the back surface portion 2R of the infusion pump 1. In this state, the fitting protrusion 571 is fitted into the first positioning hole 411 on the back surface 2R side. Accordingly, the fitting protrusion 571 and the first positioning hole 411 prevent the support member attachment unit 500 from coming off from the attachment portion 400 in the Z1 direction and falling.

In addition, the stopper portion 540 is in contact with the lower side of the third engaging portion 403. Thereby, since the attachment unit 500 of the support member is prevented from entering the Z2 direction any more from the mounted state of FIG. 8, the fitting projection 571 and the first positioning hole 411 can be aligned in the Z2 direction, The fitting protrusion 571 can be securely fitted into the first positioning hole 411. Thereby, the worker can easily perform the mounting operation of the mounting unit 500 of the support member.
In FIG. 8, when removing the fitting projection 571 and the first positioning hole 411 and removing the support member mounting unit 500 from the mounting portion 400 in the Z1 direction and removing it, the operator holds the knob of the detachable operation member 504. It is only necessary to lift the portion 570 in the RQ direction. Thereby, the attachment unit 500 of a support member can be easily removed from the mounting part 400.

  Further, in the second mounting posture RS2 of the infusion pump 1 illustrated in FIG. 17, a plurality of infusion pumps 1 are fixed to the pole 900 along the horizontal direction X. Also in this case, each infusion pump 1 is fixed to the pole 900 using a support member mounting unit 500. The treatment unit 700 of each infusion pump 1 collectively holds the infusion tube 200 and, if necessary, the electrical wiring on the infusion pump 1 side without being scattered. Accordingly, the plurality of infusion tubes 200 led out from the infusion pump 1 or the electrical wirings are securely held together as necessary, so that the appearance is improved and the infusion tube 200 is not prepared. The treatment unit 700 can hold the infusion tube 200 even when the infusion tube 200 is pulled, so that it is possible to prevent the infusion tube 200 from being burdened.

FIG. 19 is a perspective view showing a syringe pump which is another preferred embodiment of the medical pump of the present invention. FIG. 20 is a perspective view of the syringe pump shown in FIG. 19 viewed from the W direction.
A syringe pump 1001 that is a medical pump shown in FIGS. 19 and 20 is an example of a medical pump that is a medical device.

This is a micro continuous infusion pump that is used for performing micro infusion treatment of drugs such as therapeutic agents, blood transfusions, nutrients, etc. for a relatively long time with high accuracy.
Similarly to the infusion pump 1 described above, the syringe pump 1001 can be used by applying the support member mounting unit 500 and the infusion tube processing unit 700. The shape of the main body cover 1002 of the syringe pump 1001 and the shape of the main body cover 2 of the infusion pump 1 are substantially common.

  For example, the syringe pump 1001 can be set so that the syringe body 1201 of the syringe 1200 filled with a medicine does not move using the clamp 1005. When the motor M rotates the drive shaft of the syringe pusher drive unit 1007, the slider 1010 of the syringe pusher drive unit 1007 presses the syringe pusher 1202 of the syringe 1200 in the T direction, and the medicine in the syringe main body 1201. As shown in FIG. 20, the liquid is accurately delivered to the patient P via the infusion tube 1203 and the indwelling needle 1204. The syringe pump 1001 has a main body cover 1002 which is also called a main body. The main body cover 1002 is integrally formed of a molded resin material having chemical resistance, and even if a drug or the like is applied, the main body cover 1002 enters the inside of the syringe pump 1001. It has a splash-proof treatment structure that can prevent this.

  First, the elements disposed on the main body cover 1002 of the syringe pump 1001 will be described. The syringe pump 1001 has a main body cover 1002 and a handle 1002T. A display portion 1003 and an operation panel portion 1004 are disposed on the upper portion 1002A of the main body cover 1002. A syringe setting unit 1006, a motor M, and a syringe pusher drive unit 1007 are disposed on the lower portion 1002 </ b> B of the main body cover 1002. Thereby, the medical worker can perform the liquid feeding operation of the medicine from the syringe 1200 while visually confirming the information content displayed in color on the display unit 1003 of the upper portion 1002A of the main body cover 1002. Then, the medical staff can operate the operation buttons on the operation panel unit 1004 while confirming the information content displayed in color on the display unit 1003 of the main body cover 1002.

  The operation panel unit 1004 is disposed on the right side of the display unit 1003 in the upper part 1002A of the main body cover 1002. The operation panel unit 1004 includes, as illustrated in the example, a pilot lamp 4A, a fast-forward switch button 4B, and a start switch. A button 4C, a stop switch button 4D, a menu selection button 4E, and the like are arranged.

  The syringe setting unit 1006 and the syringe pusher driving unit 1007 are arranged side by side along the X direction. The syringe setting unit 1006 can select and mount the necessary amount of syringe 1200 from among a plurality of types of syringes having different amounts of accommodation. The syringe setting unit 1006 includes a housing unit 8 for housing the syringe body 1201, a clamp 1005, and a body flange gripping part 1500 for fitting and gripping the body flange 1209 of the syringe 1200. The accommodating part 1008 has a concave syringe body holding part 1008D. A tube fixing portion 1009 for detachably holding the infusion tube 1203 is formed on the wall portion at the left end of the housing portion 1008. This tube fixing portion 1009 is a groove portion that sandwiches and fixes a part of the infusion tube 1203.

  19 and 20, when a medical worker operates the clamp 1005 to remove the syringe 1200 from the syringe setting unit 1006, for example, the clamp 1005 is against the force of a spring (not shown) in the Y1 direction (frontward direction). The clamp 1005 is separated from the outer peripheral surface of the syringe main body 1201 by being pulled 90 degrees and turning 90 degrees in the R1 direction. Accordingly, the syringe body 1201 can be released from the syringe body holding part 1008D of the housing part 1008 by releasing the fixation by the clamp 1005, and the infusion tube 1203 can be removed from the tube fixing part 1009.

  Further, when the syringe 1005 is operated and accommodated in the accommodating portion 1008 of the syringe setting portion 1006 by operating the clamp 1005, the clamp 1005 is pulled in the Y1 direction against the force of a spring (not shown) to be 90 in the R2 direction. The syringe body 1201 is housed in the syringe body holding part 1008D of the housing part 1008 and the infusion tube 1203 is fitted in the tube fixing part 1009 by turning it back and returning to the Y2 direction by the force of the spring. It can be fixed by a clamp 1005.

  When the syringe body 1201 is housed and mounted in the syringe body holding unit 1008D of the housing unit 1008, the syringe pusher 1202 is disposed in the syringe pusher drive unit 1007. The syringe pusher drive unit 1007 has a slider 1010 as a moving member. When the motor M is driven by a command from the control unit, the slider 1010 pushes the pusher flange 1205 of the syringe pusher 1202 little by little along the T direction relative to the syringe body 1201. Thereby, the medicine in the syringe body 1201 can be delivered to the patient P with high accuracy over a relatively long time through the infusion tube 1203 and the indwelling needle 1204. Note that the X direction, the Y direction, and the Z direction are orthogonal to each other, and the Z direction is the vertical direction.

  In FIG. 21, a plurality of syringe pumps 1001 are fixed so as to be stacked on a pole 900 having a circular cross section, for example, along the Z direction (vertical direction). In this case, each syringe pump 1001 is fixed to the pole 900 using a support member mounting unit 500. The processing unit 700 of each syringe pump 1001 collectively holds the infusion tube and, if necessary, the electrical wiring on the syringe pump 1001 side without being scattered. As a result, the plurality of infusion tubes 1200 led out from the syringe pump 1001 are securely held together, so that the appearance of the infusion tube 1203 is improved and the infusion tube 1203 is inadvertently pulled. However, since the processing unit 700 can hold the infusion tube 1203, it is possible to prevent the infusion tube 1203 from being burdened.

  FIG. 22 shows a state in which a plurality of syringe pumps 1001 are fixed to a pole 900 along the horizontal direction X. In this case, the pole 900 is, for example, a bed railing. Also in this case, each syringe pump 1001 is fixed to the pole 900 by using a support member mounting unit 500. The processing unit 700 of each syringe pump 1 collectively holds the infusion tube and, if necessary, the electrical wiring on the syringe pump 1001 side without being scattered. As a result, the plurality of infusion tubes 1203 led out from the syringe pump 1001 are securely held together, so that not only the appearance of the infusion tube is improved, but also the infusion tube 1203 is inadvertently pulled. However, since the processing unit 700 can hold the infusion tube 1203, it is possible to prevent the infusion tube 1203 from being burdened. For this reason, the syringe connected to the infusion tube 1203 can be prevented from being pulled.

By the way, when arranging a plurality of medical pumps in the vertical direction, a rack on which a plurality of medical pumps are mounted instead of a pole is used. In this rack, a plurality of infusion tubes and electrical wiring are arranged together. Means need to be provided.
In addition, when a pole is used as the support member, it is difficult to provide means for collecting a plurality of infusion tubes and electrical wirings on the pole side. However, in the medical pump according to the embodiment of the present invention, even when fixing using a support member such as a pole, a plurality of infusion tubes are provided by providing the infusion tube processing unit 700 for the main body of each medical pump. And electrical wiring can be done easily and reliably.
In the embodiment of the present invention, even if it is a support member arranged along the first direction such as the vertical direction, it may be a support member arranged along the second direction which is the horizontal direction of the patient bed. The medical pump can be easily attached in a detachable manner. Accordingly, the medical pump can be widely used in places where a medical pump is required, such as a treatment room or a hospital room.

By the way, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made to the present invention, and various modifications can be made within the scope described in the claims.
The pressing member 503 shown in FIG. 8 has a structure in which the operator causes the pusher 532 of the male screw portion 530 to gradually advance with respect to the pole 900 by forwardly rotating the rotation operation member 531. However, the structure of the pressing member 503 is not limited to this. For example, the pressing tool 532 can rapidly advance and approach the pole 900 up to a certain point, and the pressing tool 532 approaches the pole 900. Then, the structure may be adopted in which the pusher 532 is advanced little by little, and conversely, when the pusher 532 leaves the pole 900 from the pole 900, it can be suddenly withdrawn from the pole. Thereby, the operation | work which fixes a medical pump with respect to the pole 900 can be done quickly, and also becomes easy.
