Infusion device and fixture

The present invention relates to a closed state that can be closed at an intermediate position of an infusion tube, a jig that returns to a standby infusion release state, and an infusion device that can arbitrarily attach and detach a jig.

In particular, it is a special jig for a dedicated infusion tube that can ensure the accuracy of infusion, and an infusion set that can be used for a general-purpose jig used for a universal infusion tube that cannot be connected to a drip measuring device.

The infusion device, such as the peristaltic infusion device, is a holding state of the infusion tube between the plurality of fingers and the pressing plate after the installation of the infusion tube by the pressing plate having the extruded infusion tube, by the motor Drive to deliver liquid.

The infusion set used in the infusion device has a roller clamp and a tube closing fixture near the puncture needle at the front end of the infusion tube, and the caregiver has a closed roller clamp and a tube closing fixture when the infusion tube is taken out of the infusion device after the end of the infusion. responsibility.

However, due to the recent introduction of various medical devices by hospitals and the shortage of experienced caregivers, the problem of forgetting to close the jig often occurs. Therefore, it may cause problems in patient safety.

Therefore, it has been proposed to add a kind in the middle of the infusion tube. The jig is installed in the infusion device by a clamp device method in a clamp that changes between the closed state and the standby infusion release state. When the liquid is delivered, the infusion is automatically released, and after the end of the infusion, the clamp is re-opened with the opening operation. Closed infusion set. The device further has a pressure-receiving plate for squeezing the infusion tube, and automatically closes the infusion tube closing mechanism of the infusion tube as the door opening operation is performed (for example, Patent Document 1).

The applicant of the present application also proposes a jig and a jig loading and unloading method that can be arbitrarily attached and detached to an infusion tube (Patent Document 2).

Patent Document 1: Japanese Laid-Open Patent Publication No. Hei 5-277186.

Patent Document 2: Japanese Laid-Open Patent Publication No. 2004-73822.

However, according to the infusion device described above, when the caregiver takes the jig and the infusion tube out of the infusion device, the jig is again closed due to the force application. Since the infusion tube remains closed, when the pressure to close is large, force must be applied to remove the outside of the infusion set. Moreover, since the jig is a simple large-aperture structure having continuous longitudinal grooves, the infusion tube in the longitudinal groove is easily slid and released from the closed state when subjected to a punching force or other various external forces when falling, thereby causing safety problems. Moreover, since the proper holding feeling cannot be obtained when the jig is attached and detached, the operability is not satisfactory.

In order to solve the above problem, the object of the first aspect of the present invention is to provide a clamp that can maintain the closed state of the infusion tube. When the infusion device is taken out, the clamp can be surely returned to the closed state, and the device is closed in the infusion tube. Clamping device for the downstream end of the mechanism In the case of attaching and detaching a jig, it is necessary to apply an appropriate amount of force, so that it has a feeling of holding and has an excellent inoperability.

According to the present invention, it is proposed that the clamp can be used to maintain the closed state of the infusion tube. When the infusion device is taken out, the clamp can be surely returned to the closed state, and the clamp device mechanism of the device at the downstream end of the infusion tube closing mechanism must be applied when loading and unloading the clamp. With a moderate amount of power, there is a feeling of holding and a good infusion device.

The infusion device can use a special infusion set that has a dedicated infusion tube to ensure the accuracy of the infusion, and a universal infusion set that cannot be used to ensure that the infusion accuracy must be connected to the drip measuring device with a universal infusion tube.

According to the infusion device of each of the above proposals, since a dedicated infusion set with a dedicated jig and a general infusion set for a general-purpose jig are provided, there is a problem that the use of a dedicated jig or a general-purpose jig cannot be discriminated at the time of use.

In order to solve the above problem, the present invention proposes an infusion device which can be used in a middle position of a dedicated infusion tube for ensuring the accuracy of infusion, and a special jig for changing between infusions in a closed state and a standby release state, and infusion can not be ensured. Accuracy must be connected to the universal fixture used in the universal infusion tube of the drip measuring device.

According to the first aspect of the invention, there is provided an infusion device which can be used in an intermediate position of a dedicated infusion tube for ensuring the accuracy of infusion, and in a closed state and a standby release state. A special fixture for changing between infusions, and a general-purpose fixture for the universal infusion tube that cannot be connected to the drip measuring device.

According to the infusion device of the above proposal, when the caregiver simultaneously removes the jig and the infusion tube from the infusion device, the applied force causes the jig to be turned off again. Since the closing pressure for maintaining the infusion tube closed state is increased, it is necessary to increase the force applied outside the infusion set. Since the jig is a simple large-aperture structure having continuous longitudinal grooves, the infusion tube in the longitudinal groove is easily slid and released from the closed state when subjected to a punching force or other external force when falling, which causes a safety problem.

According to the latter proposal, when the infusion set is taken out, the clamp is returned to the closed state, which may cause permanent deformation that cannot be recovered. Moreover, the clamp is easily detached from the direction of the length of the vertical infusion tube, and may cause problems if used in other infusion tubes.

In order to solve the above problem, the infusion device according to the present invention can maintain the closed state of the infusion tube by using a jig, and can not be released from the closed state including various external forces such as the flushing force at the time of dropping, and is attached to the clamp device mechanism of the infusion device. When it is released from the closed state and the liquid is started to be transported, and it is taken out by the infusion device and returned to the standby state, permanent deformation does not occur, and the closed state can be surely achieved. Since the jig does not easily fall off from the infusion tube, it is good. Security.

The infusion device comprises: sequentially pressing the infusion tube with a plurality of fingers A peristaltic infusion pump for transporting a liquid, a roller type infusion pump for infusion using a rotating roller disc for infusion, and a syringe type infusion pump for injecting a syringe piston.

In these infusion devices, a peristaltic infusion pump that inverts the infusion tube in order to perform infusion is taken as an example, and the middle position of the infusion tube that can be arbitrarily loaded and unloaded is fixed in the groove portion of the infusion pump body. After the fixed position, if the door is closed and the door is fixed to the body, the outer surface of the infusion tube is maintained by the plurality of fingers driven by the pump and the holding plate between the pressing plates of the door. The pump drives the infusion.

Recently, when the residual drug solution in the infusion tube is taken out, it is desirable to develop a leak-stop type infusion device having a function of preventing free fall.

The infusion set used in the infusion device has a roller clamp and a tube closing fixture near the puncture needle at the front end of the infusion tube, and the caretaker has a closed roller clamp when the infusion tube is taken out by the infusion device after the infusion is completed. The responsibility of the pipe to close the pipe used in the jig.

However, in recent years, as hospitals gradually introduce various medical devices and the shortage of skilled caregivers, it is highly probable that the case of forgetting to close the jig may occur. Therefore, it may cause problems in patient safety.

Wherein the leak-stop infusion device has a position between the closed state and the standby infusion release state in the middle position of the infusion tube The clamp is changed, and after the clamp is attached to the infusion device, it can automatically become the infusion release state during the infusion, and the clamp is once again closed after the infusion is completed.

However, according to the infusion device of the above proposal, when the caretaker takes out the jig and the infusion tube by the infusion device, the applied force causes the jig to be closed again. Therefore, when the closing pressure for maintaining the infusion tube closed state is increased, it is necessary to increase the force applied to the outside of the infusion set. Since the clamp is a simple continuous longitudinal groove structure with a large aperture, it includes the punching force at the time of falling, and various other external forces, which may cause the infusion tube in the longitudinal groove to move, and easily release the closed state, causing safety problems. .

According to the fixture of the latter proposal, when the infusion device is taken out and returned to the closed state, there is a possibility of permanent deformation and it is impossible to return to normal. Moreover, it is easy to fall off from the direction of the length of the vertical infusion tube, which may cause problems if used in other infusion tubes.

In order to solve the above problem, the present invention also provides a jig capable of maintaining the infusion tube closed state, including various external forces such as the flushing force at the time of dropping, and the unclosed state, and after being infused into the infusion device, the infusion state is started. When the state is released, when it is taken out by the infusion device and returned to the standby state, the permanent deformation does not occur, and the clamp can be surely closed, and the clamp can be easily removed without being easily detached.

The jig according to the present invention is a kind of which can maintain the infusion tube In the closed state, various external forces such as the flushing force at the time of falling can not be released from the closed state. After the infusion device is installed, the infusion state is released from the closed state, and the permanent infusion is not generated during the pressing, and can be surely removed when the infusion device is taken out. Returning to the closed state, the fixture with good safety will not be easily detached.

In order to solve the above problem, the object of claim 9 of the present invention is to provide an infusion device having a simple structure, which uses a jig to maintain a closed state of the infusion tube, and various external forces such as a punching force at the time of dropping cannot be released. In the closed state, after being attached to the clamp device mechanism of the infusion device, the infusion release state is started after the release of the infusion device, and when the infusion device is taken out and returned to the standby state, permanent deformation does not occur, and the closed state can be surely achieved, and the jig is not easily The ground is detached from the infusion tube. Also, an infusion device that can be operated with a small operating force when the door is closed. In addition, the infusion device is a simple infusion device.

According to the jig of the ninth aspect of the invention, it is possible to maintain the closed state of the infusion tube, and it is impossible to release the closed state including various external forces such as the urging force at the time of dropping, and after the infusion device is installed, the infusion state is released and the infusion is released. State, no permanent deformation occurs when squeezed, can be surely returned to the closed state when taken out by the infusion device, has good safety because it does not fall off easily, and can be operated with a small operating force when the door is closed. Infusion device.

Next, a preferred embodiment of the present invention will be described by way of illustration.

Next, the finger-like method proposed by the inventor of the Japanese Patent Publication No. Hei 9-151856 uses a finger to completely flatten the upstream end and the downstream end of the infusion tube to form a closed state, but does not have a closed position. The method of infusion is completely flattened, so that the infusion tube can be prevented from being affected by the thickness of the tube wall as an example.

However, it is not limited to the method, the infusion tube is completely flattened by an infusional pump of a peristaltic finger formed by a peristaltic motion, and other infusion tubes are extruded, for example, by a disc having a rotating roller for infusion. Infusion devices such as roller type infusion pumps are also applicable.

1 is a special jig 1 and a universal jig according to an embodiment of the present invention, which are preset to be stored in a transparent bag after the outlet tube 7 of the drip tube 6, and after being sterilized, the special infusion set 4 and the universal infusion set 5 are sealed. Front view. Although the illustrated kits 4 and 5 partially overlap, the illustrated dedicated jig 1 and the kit of the general jig 101 are identical.

The use cases of the dedicated infusion set 4 and the universal infusion set 5 having the dedicated jig 1 and the universal jig 101 are not particularly limited, and both of the sets 4 and 5 can be used on the infusion set. Next, a case where both sets of components can be used will be described as an example.

According to Fig. 1, the transparent bag in the special infusion set 4 is a crimped collection to ensure the accuracy of infusion, dimensions, wall thickness, material, hardness, etc., and must be strictly manufactured and managed. The length is about 2 m and the diameter is about 5 mm. Transparent special infusion tube 2. One side of the dedicated infusion tube 2 is a drip tube 6 made of a transparent resin, and the other side is a connector 13. The drip tube 6 is connected as shown by a broken line to pierce the bottle needle 8 of the infusion bag, and the outlet tube 7 of the drip tube 6 has a predetermined dedicated jig 1 as shown by a broken line.

The bottle needle 8 and the connector 13 have a cover 9 and a cover 14 respectively to maintain a sterilized state, and the cover is removed in use. There is also a puncture needle 15 prepared as a broken line in the pocket of the connector 13, and the cover 16 can be used after being removed. Viewed from the direction of the infusion, the upstream end of the connector 13 has a roller clamp 10. The roller jig 10 is composed of a resin having a quadrangular cross section, and is inserted into the infusion tube 2 as shown to form an inclined left and right grooves 11. The roller 12 can be rotationally moved in the direction of the arrow from the illustrated position, so that the distance between the intubation tube 2 and the peripheral surface of the roller 12 becomes small, and finally reaches the closed state. Therefore, the roller jig 10 can be set to the open position at the start of infusion and set to the closed position after the infusion is completed.

The above is the contents of the special infusion kit 4, the universal infusion set The content of item 5 is roughly the same. The infusion tube 3 of the general infusion set 5 is manufactured by a process in which the accuracy of the infusion cannot be ensured. Therefore, it is necessary to use a drip detecting device that can count the number of drops in the drip tube 6 (for example, 15 drops of 1 ml). Since the general infusion set 5 must be connected to the drip detection device, the price is cheaper than the dedicated infusion set 4. In addition to the contents of the above kits, some include an auxiliary belt for the auxiliary bottle needle hanging, an air vent filter, a tee for connection, and a branching tube for injecting the liquid medicine with a rubber cap.

According to the above kit, the difference from the conventional kit is that the special jig 1 is vertically fixed with respect to the drip tube outlet tube 7 having a larger outer diameter of the infusion tube, and can be moved in the direction of the infusion tube during use. Therefore, whether it is the special jig 1 or the general jig 101, the movement of the jig can be avoided, the deformation of the infusion tube, and the breakage of the transparent belt can be avoided.

Fig. 2(a) is a perspective view showing the appearance of the infusion tubes 2, 3 in an open state in the closed portion of the tube when the special jig 1 and the universal jig 101 after the injection molding of the resin are in use, and (b) is the same A perspective view of the appearance of the infusion tubes 2, 3 in a closed state in the closed portion of the tube.

According to the second (a) drawing, the jigs 1, 101 are preferably integrally formed of a nylon-based engineering plastic having a reverse elastic deformation such as polyacetal resin (trade name: Duracon). In order to close the infusion tubes 2, 3, one side of the main base portion 20 has a closing portion 21, and the other side has a closing portion 31 which, as shown, is extended from the main base portion 20 through a first elastic supporting portion 33 to the releasing direction. Formed secondary base 34.

The main base portion 20 and the sub-base portion 34 may be snapped together. When the second (b) is in the closed state, the pressing surface 41a is pressed to a position further inside than the outer peripheral surface, and the second (b) diagram can be used. The state in which the state returns to the standby release state is integrally formed.

The jigs 1, 101 are not limited to the resin molded articles described above, but it is preferable to use plastics or metals, cardboard, and combinations of these materials which do not generate toxic gases when burned.

As shown in the figure, the plate-shaped main base portion 20 formed by the plate thickness 20t cannot be bent in the thickness direction, passes through the first elastic support portion 33, and is integrally molded with the joined sub-base portion 34. The first elastic supporting portion 33 can be elastically deformed in the direction of the plate thickness 33t to form an arc and a curved surface. When the external force in the direction of the arrow F1 in the second arrow (a) is applied, the closing portion 31 on the side of the main base portion 20 moves to the closing portion 21 on the other side, and the infusion tubes 2, 3 are closed.

When the pressing faces 41a and 41a are simultaneously pressed in the direction of the arrow F2, the arc-shaped second elastic supporting portion 40 moves inward. As a result of the movement of the third hooking portion 43 inward, the jamming state with the first latching portion 23 is released. When these operations are performed, since the first elastic support portion 33 has an elastic restoring force, the sub-base portion 34 returns to the position shown in the second (a) figure, and the second and second hook portions 24, 24 and the fourth card are vertically positioned. The buckles 44, 44 will return to the stuck standby position. The release state of the infusion tubes 2, 3 is maintained by the above operation.

The position and number of the respective snap portions are not limited to the examples described.

Corresponding to the number of bits of the up-and-down switch 222, the display unit is changed to 0.1 mL/h, 1 mL/h, etc. when pressed, and the flow rate can be programmed from a minimum of 1.0 to a maximum of 500 mL/h.

Above the predetermined flow rate display portion 233 is a jig display portion 239 which is displayed when the dedicated jig 1 is used, and a general-purpose jig display portion 238 which is displayed when the general jig 101 is used.

The upper portion of the predetermined flow rate display portion 233 has a cumulative predetermined amount display portion 223 as shown. When the range of the predetermined amount is set to correspond to the upper and lower buttons of the same upper and lower switches 222, the range of 1 to 9999 mL can be set, and the setting can be set in units of 1 mL or freely set and the set value can be stored.

The display range of infusion total is 0.0~9999mL, which can be displayed in units of 0.1mL or 1mL. These flow rate display portions 233 and the accumulated predetermined amount display portion 223 are all displayed by LEDs, and therefore, can be clearly seen even in a dark room at night.

The cumulative predetermined amount display portion 223 has a warning display portion of various warning characters. As shown in the warning display section, it can illuminate the finished display portion 224 of the "completed" text, and when the detection of the infusion tube 2, 3 is closed and the liquid cannot be normally transported, the "off" warning person is turned off to display the shutdown abnormality display. Part 230, door 204 relative to this When the bottom portion 3 of the body is not completely closed, the state of the door is detected, and the door opening display portion 227 that lights the "door" character and the air bubbles in the infusion tubes 2, 3 are mixed with a bubble longer than a predetermined length (10 mm), and the "bubble" is lit. The text displays the bubble abnormality display portion 228 and, when the built-in battery voltage is insufficient, the "battery" lights up to display the battery abnormality display portion 229 and the like. In addition, when the infusion tube 2 is closed, the high pressure of the alarm pressure is "H", the medium pressure of "M", and the low pressure of "L" are set, and the display unit is set in the horizontal direction of the three-stage green light-emitting diode. The preset off detection alarm pressure is displayed frequently. The light emitting diodes are packaged on the same package substrate, and the flexible circuit board supplies power. The uppermost portion of the display portion 208 has a jig display portion 237 displayed by the lamp 237a.

The door base 204a, which is indicated by a broken line, is made of aluminum cast or rigid resin, and the design is focused on forming a curved surface between the side surface and the front surface while forming a convex protrusion thereon and having an action indicator 206. The inside of the action indicator 206 is a red and green light emitting diode, which is illuminated according to the operating state. That is, it is turned off when the liquid is transported and when it is transported quickly, and red and green are alternately lit during the standby, so that the state of the infusion can be recognized from a distance.

Fig. 11(a) is a front view showing the open state of the door 204 of the infusion device 200, and Fig. 11(b) is a side view showing the appearance of the inclined member 50. To illustrate the state of the infusion device 200 when the door 204 is open, the figure is the state in which the door 204 is open relative to the body bottom 203, and the door 204 can be opened to a predetermined size of about 105. Degree of angle and has a stop stop card. (b) An oblique view of the inclined member 50 before being inserted into the door 204.

According to the eleventh (a) drawing, the description of the members denoted by the same reference numerals is omitted, and the infusion device 200 is a specific cover 212 with a specific resin material and a special injection molding which does not generate a resin flow mark, and the bottom portion 203 of the body is provided. The four corners are covered and fixed, and after the integrated cover 212 is taken out, all the internal parts can be simply assembled.

On the integrated cover 212 there is a handle 205 that can be held in use. As shown in the figure, the main body bottom portion 203 has an upper and lower groove portion 203m integrally formed near the center position, and the infusion tubes 2, 3 can be installed in the groove portion 203m.

Below the groove portion 203m, there is a pump mechanism 201 that can be attached and detached by four screws by a cross screwdriver. When the pump mechanism 201 is contaminated by a chemical solution or the like, the fingers 201a, 201b, 201c, 201d, and 201e are not easily operated. The pump mechanism 201 is taken out from the bottom 203 of the body, and the liquid is cleaned with a specific detergent to restore the action to normal. Therefore, the finger of the pump mechanism 201 is formed by injection molding of a drug-resistant liquid and a thermoplastic resin having excellent resistance to cockroaches such as a polyacetal resin material.

A lower portion of the main body bottom portion 203 has a pair of protruding portions 203a integrally formed by the protruding paper surface. When the covered door 204 is closed, the upper portion of the protruding dam portion 203a is opposite to the lower side of the covering door, regardless of the external force being applied. The crotch portion 203a will withstand external forces and allow coverage The door and door 204 are not directly subjected to external forces.

The middle right side of the bottom 203 of the main body is fixed by a hook 259, and the locking portion 207a of the door latch 207 which can be arbitrarily rotated on the door 204 is caught by the hook 259, so that the door 204 can be maintained in a fixed state with respect to the main body.

The opposite door 204 of the uppermost end of the groove portion 203m has a door sealant 266 formed by an elastic body. When the door 204 is closed, a joint sealing surface is formed with the body bottom portion 203 as shown in the shape portion 203j to allow the door sealant 266. Deformation prevents the liquid medicine from entering the inside. The door sealant 266 is fixed by a tube pressing plate 267 fixed to the door 204 to prevent falling off.

A bubble sensor 260 is provided below the shape portion 203j. The bubble sensor 260 can detect bubbles that are mixed into the infusion tubes 2, 3 beyond a predetermined length (for example, 10 mm) and a predetermined amount (about 0.08 cc) of the tube, and forcibly stop the subsequent action, and the opposite side of the bubble sensor 260 When the tube pressing plate 267b is formed integrally with the tube pressing plate 267, and the door 204 is closed, the infusion tubes 2, 3 can be accurately detected when the infusion tubes 2, 3 are in a stationary state.

Below the bubble sensor 260 is the position of the pump mechanism 201, below which there is a closing sensor 262, and a gimbal-type closing plate 269 on the opposite door 204 is in the front-rear direction of the paper. Hold the infusion tubes 2, 3. The closing sensor 262 is composed of a permanent magnet and an analog detector that detects the moving position of the permanent magnet to detect the closed state of the infusion tubes 2, 3, and the movement of the permanent magnet position caused by the change in the internal pressure. According to the description, the closing plate 269 is closed. There is no need to limit the change in internal pressure of the infusion tubes 2, 3 in any direction, and the illustrated disc is the bottom of the spring plate (elastic member) to maintain free movement.

The operation principle of the pump mechanism 201 is that the infusion tube 2 of the device is pressed by the fingers 201a, 201b, 201c, 201d, and 201e to continuously deliver the liquid at a set time flow rate, and according to the data stored by the microcomputer (CPU). A signal that produces motor rotation, a rotation signal that controls motor rotation, drives the pump, and regulates infusion flow. The fingers are the first finger, the second finger, the third finger, the fourth finger, and the fifth finger, respectively, from the upstream end, and are respectively in the bottom of the pump. The front and back directions of the paper are driven in reverse.

As shown, the shapes of the first finger and the fourth finger are different from those of the other second finger, the third finger, and the fifth finger. That is, the width W1 of the first finger and the fourth finger is larger than the width W2 of the other fingers. Further, the pressing faces of the first finger and the fourth finger have convex portions.

Since the shape of each of the fingers is not completely the same, the present applicant has proposed a peristaltic finger method which can be implemented in Japanese Patent Laid-Open Publication No. Hei 09-151856.

That is, the convex portions formed on the pressing faces of the first finger and the fourth finger completely close the upper end and the downstream end of the infusion tubes 2, 3, and the other second fingers, The third finger is not fully pressed at the intermediate position, so it can be achieved without being affected by the thickness of the infusion tube wall. High precision infusion. When the first finger and the fourth finger completely press the infusion tube 2, the infusion tubes 2, 3 are widened to the left and right, and therefore, the width W1 of the first finger and the fourth finger must be higher than the other. The width of the fingers is large W2. The fifth finger 201e is for compensating for the pulsation.

In the general peristaltic motion mode, all the fingers are transported by the peristaltic motion of the infusion tube in such a manner as to flatten and completely press the infusion tubes 2, 3 as in the second finger 201b.

The door 204 is opposite to the body bottom 203, and is formed by a pair of upper and lower hinges 265 and a dotted line plug 261, and the display portion 208, the button panel portion 209, the power source of the action indicator 206, etc. Then, it is supplied through a flexible circuit board 263 which can be flexibly reversed. The central portion of the door 204 has a backing plate mechanism 230 at the opposing pressing plate of the pumping mechanism 201.

The back plate mechanism 230 and the fingers of the pump mechanism 201 are disposed opposite to each other, and the pressed surface formed by the fingers is moved toward the front and back of the paper. When the load is too large, the paper is retracted in the direction of the paper to avoid damage to the infusion. Tubes 2, 3. Since the first finger and the fourth finger completely press the infusion tubes 2, 3, the opposing back plate members 231 and the back plate bottoms 232 of the fingers are individually moved in the front-rear direction of the paper.

Below the closing sensor 262, the movable infusion tube closing piece 51 and the fixed infusion tube closing piece 52 constituting the infusion tube closing mechanism are moved to the illustrated release position when the door 204 is closed.

A rotating arm 53 of the jig handling device is provided below the movable infusion tube closing piece 51, and an opening guiding portion is formed on the other side of the device jig. Further, the fixed infusion tube closing piece 52 has a guiding member 54 below, and the other side is provided with an opening guiding portion. A lower guide member 56 is fixed below the turning arm 53.

The back surface of the infusion device 200 is an external signal connector (not shown), a fuse slot and an AC power connector (pin plug), and a lister switch and a DC connector that are packaged on a motherboard (not shown). The opening is connected to the outside.

According to the eleventh (b)th view, the inclined member 50 fixed to the inner side of the door 204 of the infusion device 200 is fixed to the inner surface of the door 204 by a spring, together with the folding surface 53f of the rotating arm 53 which will be described later. The inclined surface 50c, the second inclined surface 50a of the pressing surface of the pressing jig 1, 101, the groove portion 50b inserted into the first extending portion 22, and the third inclined surface in which the valley is disposed opposite to the second inclined surface 50a The surface 50d or the like is integrally molded in a shape as shown in a predetermined resin material such as polyacetal resin.

Fig. 12 is a cross-sectional view showing the state in which the infusion tubes 2, 3 are in the infusion set 200 and the door 204 is closed. In the figure, the description of the members denoted by the same reference numerals is omitted, and the bottom portion 203 of the main body is integrally formed with a shape portion 203t which can accommodate the pump mechanism 201 and a crotch portion 203a which are indicated by broken lines in the drawing.

The crotch portion 203a is the same height as the door 204 to protect the door 204. The body bottom 203 is an assembly base of each member, as shown by an aluminum cast upper plate The member is fixed to the upper plate to form an upper frame portion. The back surface portion of the upper plate is a back plate formed of an iron plate having a thickness of about 1 to 2 mm to form a back surface member, and the upper plate has screw holes fixed to the back side of the device by two screws to form a rear outer frame portion. The lower portion of the body bottom 203 and the back plate are screwed lower plate members and form the bottom frame portion of the device. The body bottom 203, the upper plate, the back plate, and the lower plate form a strong outer frame structure. It does not matter whether the upper plate, the back plate, the lower plate, and the battery case 241 are integrally formed.

According to the above, the upper and lower plates and the built-in mechanism and the substrate constitute an integrated and highly rigid structure based on the bottom portion 203 having high strength, and the mechanism and the circuit can be protected in case of accidental dropping. And isolate the electromagnetic wave to achieve the minimum impact.

The upper and lower portions of the shape portion 203t of the body bottom portion 203 support the cam shaft 248 that can be arbitrarily rotated with the built-in bearing. The shaft body at the upper end of the cam shaft 248 is a gear 247 fixed by a screw (not shown). The upper plate is a power output shaft, and has a gear 1241 that is fixed to the fixed stepping motor 240 by a screw (not shown) or smaller than the gear 247, and the rotational force of the stepping motor 240 is transmitted between the gears by the belt 242. Camshaft 248. As shown in the figure, the edge of each gear can eliminate the need to take out the stepping motor 240 when replacing a belt having a convex tooth on one side.

The outer peripheral surface of the cam shaft 248 is an eccentric convex shaft shape portion corresponding to the fingers, and is integrally processed by a computer controlled processing device in order to ensure accuracy. Due to the high precision of the camshaft 248, if the size is used High precision infusion tubes can achieve flow accuracy of, for example, within ±5%. The integrally formed cam shaft 248 is mechanically machined from SUS304 stainless steel. The rotation detecting sensor 246 is attached to the upper side of the gear 247, and the rotational position and the number of rotations of the cam shaft 248 are optically read in cooperation with a timing disc not shown. Therefore, it is necessary to fix the rotation detecting sensor 246 to the fixing portion integrally formed on the upper plate.

The back plate is mounted on the back of the motor 240 as shown in the figure, and serves as a base portion of the substrate such as a power connector. The battery unit is located below the motor 240, and the battery can be replaced through the opening on the lower plate.

After the above-described pump mechanism 201 is fixed to the shape portion 203t by four screws, the small radial bearing of the finger described later is brought into contact with the convex axis surface of the cam shaft. Since the upper plate and the gear are in a disengaged state, when the cam shaft is fixedly coupled to the upper plate, or fixed after the cam shaft is combined, there is no problem that the combination cannot be sequentially performed. The battery unit is fixed to the lower plate as shown. Further, the flexible circuit board 263 extends through the opening of the main body bottom portion 203 from a main board (not shown).

The storage device and the motherboard for which predetermined control is performed are assembled upward and have a plurality of connectors, and the motherboard is screwed to the upper edge of the side of the upper plate. The motherboard has a grounding pattern, so in addition to the wiring of the electronic components, noise interference of various devices in the operating room can be avoided.

Fig. 13(a) is a side view showing the appearance of the special jig 1 and the general jig 101 before being attached to the jig device mechanism, and (b) the appearance of the jig device mechanism after being installed from the front obliquely upward. .

In the figure, the description of the members indicated by the same reference numerals is omitted, and the shape of the reinforcing guide portion 30 integrally formed with the main base portion of the jigs 1 and 101 as the guide member 54 as the opening guide portion is formed to form an opening groove portion 54a having the inner dimension as shown in the drawing. . The center groove portion 54b is formed at the center of the opening groove portion 54a, and after the main base portion is inserted, the restriction portion 25 formed on the first extension portion 22 is restricted by the position of the surface 54f of the guide member 54 and cannot be pushed into the above position.

The turning arm 53 is folded into contact with the outer peripheral surface of the second elastic supporting portion 40 to form a contact convex portion, so that the jig is inserted when the jig is inserted. The lower member 56 and the guiding member 54 are resin molded articles of the same color, and are fixed together below the movable infusion tube closing piece 51 constituting the infusion tube closing mechanism and the fixed infusion tube closing piece 52.

Fig. 14 is a side view showing the appearance of the infusion device 200 as viewed obliquely from the infusion tube 2, using the dedicated jig 1 and the general-purpose jig 101 in a closed state. Fig. 15 is an operation manual 57 on the side of the infusion device 200.

The description of the members denoted by the same reference numerals is omitted in the two figures, and the jigs 1, 101 are closed from the outlet pipe of the drip tube 6 to the lower side of the infusion tubes 2, 3.

The door 204 of the infusion device 200 is opened and set according to the instruction 57 of Fig. 15. That is, the door 204 is opened, the tube closing mechanism is released, and the infusion tubes 2, 3 are loaded into the groove of the groove 203m and the red tube guiding 268 under the infusion mechanism 201 (that is, "the pump mechanism"), and the clamps 1, 101 are respectively An insertion guide between the guiding member 54 and the turning arm 53 is inserted. Then, the door handle 207 of the door 204 is closed to fix the main body, and the closed state is released, and the release state is released to start preparation of the infusion.

When the clamps 1 and 101 are dropped or subjected to the urging force in the closed state, the door 204 is not closed, and the door 204 is closed. After the release state is released, the clamp is instantaneously changed from the state of the second (b) to the second (a). In the state, each buckle portion cannot be recovered due to permanent deformation. That is, when the door 204 is closed, the release of the closed state does not cause the permanent deformation of the jig to change the shape of the jig and affect the stop mechanism of the door interlocking jig mechanism. The test results are displayed on the operation panel, taking into account the fact that both the dedicated infusion kit and the universal infusion kit's dedicated infusion kit and universal infusion kit are available.

When using a special infusion set that can ensure an infusion accuracy of 10%, it can be directly used on an infusion pump. If a general infusion set is used, since the accuracy cannot be ensured, the drip sensor 47 must be counted by optical drops, for example, 15, 20 60 drops are detected by 1 ml, and the infusion set used in the setting of the number of drops preferably has a changeover switch. When using IC tags, barcodes, etc. for automatic detection, the user can set the number of drops from the panel.

The reinforcing guide portion 30 is a wall portion designed to prevent erroneous insertion in order to prevent the jigs 1, 101 from being inverted. Further, when the hand device is used as the jig, the restricting portion 25 having the step portion can be used as a target for the device jig. The feeling of getting stuck in the device is caused by the convex portion of the rotating arm. In order to prevent the caregiver from grasping the clamp and the tube at the same time, the pipe is flexed to release the closed state to cause an external leak, and a protrusion is provided. Since the dedicated infusion set and the universal infusion set are packaged together with the jigs 1, 101 and the clips are prevented from falling off, they are packaged in the form of the jig. This also avoids backflow during reverse loading. Moreover, the special infusion set and the universal infusion set are displayed in different colors, so they can be easily distinguished (white, orange).

Fig. 16 is an exploded perspective view of the clamp device mechanism as viewed from below, and Fig. 17(a) is a bottom view of the clamp device mechanism before the special jig 1 and the universal jig 101 are loaded, and Fig. 17(b) shows the special jig 1 attached thereto. The bottom view after the clamp device mechanism and the 17th (c) view are the bottom views of the universal jig 101 attached to the clamp device mechanism.

The function of the clamp device mechanism includes, as described with reference to Fig. 11(b), the tilting member 50 fixed to the inner side of the door 204 of the infusion device 200, and by the opening and closing operation of the door 204, the folded surface 53f of the rotating arm 53 is pressed. The first inclined surface 50c of the inclined member 50 and the one side of the pressing surface 41a of the jigs 1, 101 are pressed against the second inclined surface 50a to perform the first function of the closed state and the released state, and the detection special-purpose jig 1 and the general-purpose jig 101 device state. The second function.

The structure to be described later is only one embodiment. In order to achieve the first function and the second function described above, the shape and size of the jigs 1, 101 can be appropriately changed, and an individual mechanism can be used. If a special jig 1 or a general-purpose jig is used, In the case of the dedicated fixture device mechanism of 101, the state of the device can be detected by RF in combination with an optical or IC tag.

According to Fig. 16, referring to Figs. 13(a) and (b), an opening portion into which the jigs 1, 101 are inserted is formed between the guiding member 54 and the turning arm 53 indicated by broken lines.

The bottom portion 58 further includes a large bolt shaft body 59 having a groove portion of the fitting wheel 62, and a small bolt shaft body 61 having a groove portion fitted with the same stopper wheel 62, which is press-fitted in the vertical direction.

The turning arm 53 is integrally formed of a resin material such as PPS resin as shown in the figure. One side of the turning arm 53 has a through hole 53a into which the bolt shaft body 59 is inserted, the other side forms a folded surface 53f and a convex portion 53b, and a folded surface 53d and a body 53k (indicated by a broken line) are formed on the right side of the drawing, from the body 53k The extension portion 53m is formed on the inner side surface of the protrusion portion 53g while the extension portion 53m is folded, and the folding protrusion portion 53s illustrated by a broken line is folded with respect to the bottom portion 58. It is integrally formed with the inside of the body 53k. The through hole 53a of the turning arm 53 is inserted into the bolt shaft body 59 of the bottom portion 58 and then the retaining wheel 62 is attached to achieve the purpose of arbitrarily rotating without falling off.

The ends 60a, 60b of the compression coil 60 are respectively located between the projection 58a of the bottom portion 58 and the projection 539 of the pivot arm 53 while being pre-stressed to cause slight compression in a natural state. Therefore, the folded surface 53d of the body 53k is brought into contact with the second curved portion 58c. As a result, the turning arm 53 that is biased by the compression coil 60 rotates counterclockwise with the shaft 59 as the axis.

Special fixtures and universal fixtures can be used to achieve non-contact and reliable detection resolution using IC tags. In the figure, the bottom portion 58 has a disc 63 which is arbitrarily rotatable relative to the shaft body 61, and the disc 63 can optically detect the rotational position when the insertion jig is rotated. This makes it possible to achieve the purpose of the test fixture in a limited volume.

The disk disc 63 is made of enamel resin which is impenetrable by light, and has a through hole 63a at the center of rotation, a notch portion 63b of the peripheral surface, a recess 63c, and a notch portion fixed to the other side 65c of the torsion spring 65. 63d. The end portions 65b, 65c of the disc 63 compress the coil portion of the torsion spring 65 to generate an elastic restoring force, and the shaft body 61 of the bottom portion 58 is inserted and the retaining wheel 62 is attached to achieve the purpose of arbitrarily rotating and preventing falling off. .

The notch portion 63b can be inserted into the first recess portion 26a of the dedicated jig 1 and the second recess portion 27a of the universal jig 101 to transmit the rotation in the forward and reverse directions. When the force is taken out, each of the jigs is returned to the initial position by the restoring force of the torsion spring 65 and the contact force of the inclined faces of the recesses 26a and 27a. Therefore, even when there is a chemical liquid, it is possible to surely return to the initial position.

The first inductor 67 and the second inductor 66 for detecting the rotation concave portion 63c of the disk 63 are constituted by a light-emitting element and a light-receiving element which are fixed to the sensor substrate 68 across the disk 63, and the sensor substrate 68 is fixed to the bottom portion 58. The curved part 58k. In addition to using a light transmissive light sensor, a magnetic sensor can also be used for detection.

17(a), (b), and (c) are omitted from the description of the members denoted by the same reference numerals, and the first of the concave portions 63c of the disc 63 is detected before the device-specific jig 1 and the general-purpose jig 101 as shown in Fig. 17(a). The inductor 67 and the second inductor 66 block the optical axis. The notch portion 63b is stopped at a position about 15 degrees from the parallel axis. The turning arm 53 stops at a position perpendicular to the parallel axis of the folding surface 53d and compresses the coil 60 in the same direction.

From the state described above, the dedicated jig 1 or the general-purpose jig 101 is inserted between the guide member 54 constituting the one opening portion and the convex portion 53b of the turning arm 53 of the other opening portion in the direction of the arrow, as shown in Fig. 17(b) and 18 (c) The state of the graph.

When the dedicated jig 1 is attached to the jig mechanism, as shown in Fig. 17(b), the contact surface 63b-1 of the notch 63b of the disc 63 is in protruding contact with the front end of the insertion guide 26 of the special jig 1, and is moved back and forth. The first recessed portion 26a is inserted into the convex portion 63b-2 of the notch portion 63b, and the disc 63 is rotated by a predetermined angle with respect to the shaft 61, and the first induction cannot be blocked. The optical axis of the device 67 can thus detect the recess 63c. At this time, when the convex portion 53b passes the outer peripheral surface of the second elastic supporting portion 40, there is a feeling of being caught, and the restricting portion 33a comes into contact with the stopping member 58c to prevent the above insertion.

Fig. 17(c) is a bottom view of the general-purpose jig 101 attached to the jig device mechanism, and the general-purpose jig 101 is attached to the jig device mechanism as shown in the figure, and the contact surface 63b-1 of the notch portion 63b of the disk 63 is inserted and guided by the general-purpose jig 1 The front end of the portion 27 is in contact with each other, and then moves forward and backward to a position where the second concave portion 27a is deeper than the convex portion 63b-2 of the notch portion 63b.

As described above, when the insertion guide 27 is used longer than the dedicated jig, the disc 63 can be rotated by a predetermined angle of 15 degrees to reach the stop position, and since the optical axis of the second inductor 66 cannot be shielded, the recess 63c is used. Test. At this time, the convex portion 53b has a feeling of being caught when passing through the outer peripheral surface of the second elastic supporting portion 40, and the restricting portion 25 is in contact with the guiding member 54 to prevent the above insertion.

When the loading and unloading are performed, the turning arm 53 is folded into contact with the folding surface 53d of the reinforcing guide portion 30 of the jig. As a result, the compressive force of the compression coil 60 causes the turning arm 53 to slightly rotate in the counterclockwise direction to have a grip feeling.

Fig. 18(a) is a cross-sectional view of the main body 53k of the turning arm 53 taken obliquely when the jig device mechanism door 204 is opened, and before the special jig 1 is attached to the jig device mechanism, and Fig. 18(b) is a view A cross-sectional view of the special jig 1 after it is attached to the jig mechanism.

In the same figure, the description of the members denoted by the same reference numerals will be omitted. When the door 204 is opened, as shown in the figure, the first inclined surface 50c, the second inclined surface 50a, and the third inclined surface 50d of the inclined member 50 are largely retracted. The folding surface 53f of the main body 53 of the turning arm 53 is located at the opposite position of the guiding member 54, and the infusion tube 2 in which the dedicated jig 1 is closed is inserted into the opening formed therebetween in the direction of the arrow. At this time, the folded surface 53d of the turning arm 53 comes into contact with the reinforcing rib 37 of the jig 1, and thus there is a moderate resistance. The reinforcing guide portion 30 is attached to the guide groove portion of the guiding member 54, which can avoid insertion errors. At this time, the disc 63 will stop at the same position as the 17th (a) figure.

Next, after attaching the special jig 1 to the jig device mechanism according to the 18th (b) figure, the feeling of the stuck feeling is obtained, and the result is as shown in Fig. 17(b). It is known from the electrical signal of the sensor 67 whether or not the dedicated jig 1 has been loaded onto the infusion device 200. The door 204 is then closed in the direction of the arrow.

When the door 204 of Fig. 19(a) is closed, the dedicated jig 1, the turning arm 53, and the contact member 50 are in a pressed state. In other words, when the pressing surface 41a of the special jig 1 is pressed against the inside of the second inclined surface 50a of the inclined member 50 in the buckle releasing direction, the lifting is started as shown in Fig. 2(b). At the same time, as shown in the figure, the folded surface 53f of the turning arm 53 is pressed against the first inclined surface 50c of the inclined member 50, and is rotated counterclockwise by the compressive force of the compression coil.

Next, according to Fig. 19(b), when the door 204 is closed to an angle of about 1 degree with the infusion device, the second inclined surface 50a is further pressed to the pressing surface 41a of the special jig 1 to be released soon. Buckle status.

As shown in Fig. 20(a), the door 204 finally closes the lock and releases the closed state of the special jig 1 and the infusion tube. At this time, due to the elastic force, the pressing surface 41a of the first extending portion 41 instantaneously returns to the natural state without being permanently deformed when it is separated from the valley of the inclined member 50. When the turning arm 53 is moved to the standby position as described above, the sub base formed by the reinforcing rib 37 on the special jig 1 is moved to the side of the turning arm 53. By the action, it becomes a state in which a liquid can be transported.

If the clamp is to release the buckle, the door 204 can be closed with a slight force as long as the point of application of the force is changed.

Infusion is performed using the peristaltic motion in the stated state.

After the completion of the infusion, as shown in Fig. 20(b), the first inclined surface 50 of the tilting member 50 of the turning arm 53 is separated from the folding surface 53f, and the dedicated jig 1 starts to press to the right. At this time, the second inclined surface 50a of the inclined member 50 starts to be separated from the pressing surface 41a of the first extending portion 41.

As shown in Fig. 21(a), when the door 204 is further opened to the angle 8 or so, the turning arm 53 is moved to the pressing position and the special jig 1 is returned to the stuck state and the infusion tube is closed. Next, as shown in Fig. 21(b), the state in which the door 204 can be opened can be removed.

Finally, Fig. 22(a) is a cross-sectional view showing the state in which the special jig 1 is taken out, and the caretaker takes out the grip portion of the special jig 1 up and down from the front, and the feeling of holding is described. When taking out, as shown in Fig. 22(b), the disc 63 is forcibly rotated to return to the initial position.

As described, the clamp of the special infusion set and the clamp of the universal infusion set can be automatically inspected, and when the clamp device is converted into a rotary motion from the parallel motion, the notch portion of the non-detection portion and the two light transmissive sensors are The torsion spring has a disc in the standby position, so it can be installed in a limited space. When the jig is taken out, the notch portion of the disc is returned to the original position. Therefore, even if the chemical liquid (and after drying) is used, the torsion spring cannot be returned to the original position, so that it can be forcibly returned to the original position, so the next time it is used, Will cause problems.

Fig. 23 is a flow chart showing the automatic detection of the dedicated jig 1 and the general jig 101. Step S1 in the figure refers to the description of Fig. 15 to set the jig and the infusion tube. When using a universal infusion set, the drip tube with the spot check probe must be mounted on the drip device and the drip device attached to the infusion set.

Next, in accordance with step S2, the maintenance gate 204 is opened and the power supply sensing 215 is turned ON for about 1 second to initialize the program, and initialization and self-checking of each device are performed, and if an abnormality occurs or a warning is issued, the subsequent operation is stopped.

Next, in step S3, the dedicated jig 1 and the general-purpose jig 101 are set, and in step S4, the door 204 is closed, and the jig is released.

Then, according to step S5, the special fixture 1 or the universal fixture 101 can be detected by the sensors 66 and 67. If it is recognized as the special fixture 1 according to step S6, the process proceeds to step S7, and the display light of the special fixture 1 is simultaneously displayed. Then, proceeding to step S8, the liquid is delivered.

If the step S6 recognizes that the special jig 1 is not the dedicated jig 1 but the general-purpose jig 101, the process proceeds to step S9, and the display lamp of the general-purpose jig 101 is simultaneously displayed, and then proceeds to step S10 to determine whether or not the drip detection probe is connected, and if the connection is confirmed, the process proceeds to the step. S8 begins the infusion. If the step S10 is missed and the dot detecting probe is not connected, the process proceeds to step S11 to issue a warning to notify the person.

According to the above description of the present invention, it is not necessary to insert the infusion tube in advance, and the jig can maintain the closed state for a long time. However, if the clamp is released from the closed state of the infusion tube due to the switching action of the door, it can be returned to the closed state again. Moreover, the jig does not accidentally disengage from the infusion tube, and can provide a highly reliable jig and an infusion device using the jig.

Fig. 24 is a cross-sectional view showing the dedicated jig 1 in a closed state when the door 204 of the other embodiment is opened. According to the figure, the description of the members denoted by the same reference numerals is omitted, and the door 204 is opened to the left side with respect to the pivot pin 261 of the body bottom 203. The door 204 has a contact surface 204a in the vicinity of the plug 261.

A shaft body 59 is provided on the bottom portion 58. As described, the rotatable pivot arm 53 rotates counterclockwise with the shaft body 59 as the axis. The ends 60a, 60b of the compression coil 60 are located between the projection 58a of the bottom portion 58 and the projection 300a of the moving member 300, as shown, with a naturally compressed preloaded state.

The moving member 300 is made of, for example, a resin and has a contact surface with the door 204. The front end of the contact portion 301 that is in contact with the 204a is integrally formed and moved by the compressive force of the compression spring 60. One side of the bottom 58 shaft body 303 is a rotation shaft that can be arbitrarily rotated, and the other side is a shaft body 302 of the moving member 300. The first coupling member 305 located inside the moving member 300 can be arbitrarily rotated with respect to the shaft body 302. The turning arm 53 is fixed to the shaft body 304. One side of the shaft body 304 is an arbitrary rotating shaft, and the other side is a second connecting member 306 whose surface side is rotatably movable relative to the moving member 300 and the shaft body 302. Since these joining members 305, 306 are subjected to compressive and tensile forces, it is preferable to use a metal product having strength. The connecting member 306 has a notch that is in contact with the shape portion 310 of the moving member 300 as shown in the drawing, so that movement other than the illustrated state can be restricted.

Fig. 25 is an operation explanatory view of Fig. 24, in which the moving member 300 is moved in the direction of the arrow D2 by the compression force in the direction of the arrow D1 of the compression spring 60. The movement is caused to move laterally with the connecting members 305 and 306, and the connecting member 306 moves the turning arm 53 in the direction of the arrow D3 to maintain the closed state of the jig 1.

Next, Fig. 26 is a cross-sectional view showing the door 204 closed and the dedicated jig 1 turned into an open state. When the door 204 is closed, the contact portion 301 of the moving member 300 and the contact surface 204a of the distance plug 261 L are moved by contact by a half turn of the rotating arm 53 as shown. As a result, the dedicated jig 1 becomes an open state. Figure 27 is another embodiment. When the door 204 is closed, the special jig 1 is in an open state. When the door 204 is closed, the moving member 300 moves in the direction of the arrow D4 to compress the compression spring in the direction of the arrow D5. move. This movement is caused by the movement of the connecting members 305 and 306 toward each other, and the turning arm 53 is moved in the direction of the arrow D7. By the action of the inclined surface, the jig 1 is brought into an open state and maintained in this state.

As with the structure, the operating force when the door 204 is closed can be reduced.
