Description

Dispensing system and dispensing method

Technical Field

The invention mainly relates to the field of automatic dispensing, in particular to a dispensing system and a dispensing method suitable for running on the dispensing system.

Background

In modern medicine, infusion therapy is widely used as an effective treatment means in the course of treatment against various diseases. To achieve a better therapeutic effect, the medical fluid to be delivered to the patient typically comprises saline and one or more drugs. The modern infusion treatment is generally carried out in a mode of independent storage, namely, the infusion bag generally only contains physiological saline, and the medicines are usually contained in penicillin bottles, ampoule bottles and the like so as to be stored conveniently. The reason for such independent storage is that the storage requirements of various drugs are different, and the types and concentrations of the drugs in the drug solutions to be finally infused in the treatment of different patients are different. The storage mode of independent storage requires dispensing of the infusion bag before infusion is performed on the patient.

Currently, the dispensing of infusion bags is done manually by a nurse. Manual dispensation by a nurse ensures that the infusion bag is dispensed accurately and that the various medications are kept in a suitable condition for storage prior to use, but such dispensing methods still have some improvements. On the one hand, the nurse often needs to make a round trip to grip infusion bag, xiLin bottle and ampoule when dispensing to infusion bag, and the operation cylinder is operated on one hand, and operating procedure is more complicated, and then leads to the whole efficiency of dispensing on the low side. On the other hand, manual dispensing presents a risk of error. The consequences of dispensing errors are often severe.

There is therefore a need for an automated dispensing system and method of dispensing suitable for operation on the dispensing system.

In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

Furthermore, each of the embodiments described below has one or more technical features, and thus, the use of the technical features of any one embodiment does not necessarily mean that all of the technical features of any one embodiment are implemented at the same time or that only some or all of the technical features of different embodiments are implemented separately. In other words, those skilled in the art can selectively implement some or all of the features of any embodiment or combinations of some or all of the features of multiple embodiments according to the disclosure of the present invention and according to design specifications or implementation requirements, thereby increasing the flexibility in implementing the invention.

An embodiment of the dispensing system and dispensing method of the present invention will be described with reference to fig. 1 and 2. In the present embodiment, the dispensing system 100 includes an infusion bag holding assembly 110, a vial holding assembly 120, a syringe moving device 130, a syringe manipulator device 140, a waste port 150, and a controller. Wherein the infusion bag holding assembly 110 is capable of holding the infusion bag 200 such that the infusion bag 200 is in a state convenient for dispensing. The particular manner in which the bag 200 is held by the bag holding assembly 110 may vary. For example, in some embodiments, the bag holding assembly 110 is an open container adapted to receive an infusion bag 200.

The penicillin bottle holding component 120 can hold the penicillin bottle 300, so that the process of extracting the medicine in the penicillin bottle 300 can be kept stable. The penicillin bottle holding component 120 can also shake the penicillin bottle 300, so that the medicine in the penicillin bottle 300 can be uniformly mixed with the liquid injected into the penicillin bottle 300. The syringe moving means 130 can move the syringe 400 in horizontal and vertical directions so that the syringe 400 can be aligned with the infusion bag 200, the vial 300, or the waste port 150. The syringe operation device 140 can control the syringe 400 to perform the operations of sucking and injecting, thereby performing operations of sucking liquid from the infusion bag 200, injecting liquid into the vial 300, sucking liquid from the vial 300, and the like. The waste port 150 is connected to an external waste collection device to receive waste.

The controller is connected to the vial gripping assembly 120, the syringe moving device 130, and the syringe manipulator 140, and is capable of controlling the vial gripping assembly 120, the syringe moving device 130, and the syringe manipulator 140 to dispense the drug. Wherein the specific location and form of the controller may vary. The controller may be disposed inside the apparatus shown in fig. 1, or may be disposed outside the apparatus and connected to the vial gripping assembly 120, the syringe moving device 130, and the syringe handling device 140. The controller is therefore not shown in fig. 1.

It is noted that FIG. 1 shows only a portion of a dispensing system according to one embodiment for ease of illustration. The dispensing system in some embodiments may in fact include more structures. For example, vial gripping assemblies 120 and bag gripping assemblies 110 are disposed at the edge of a rotating table and can rotate with the rotating table, and the rotating table has waste ports 150. In these embodiments, the dispensing system also has a plurality of pipette moving devices 130, and a pipette handler 140 is disposed on each pipette moving device 130. The plurality of syringe moving devices 130 are disposed on a rail above the rotating table and can perform a horizontal movement along the rail.

Referring to fig. 1-3 in some embodiments, the dispensing system 100 may perform the following dispensing method, under the control of the controller:

in step 11, the infusion bag 200 is sucked by the suction/injection device 400. If air is present in the bag 200, the air will be concentrated on the uppermost side of the bag 200 when the bag 200 is held by the bag holding assembly 110. When air is present in the infusion bag during this suction operation, the air is collected at the uppermost portion of the infusion bag 200 and is drawn out by the suction syringe 400. If the bag 200 has less air, the syringe 400 will draw out a portion of the air and a portion of the base fluid (typically saline) in the bag 200. If there is no air in the infusion bag, the syringe 400 will only draw out the base fluid.

In step 12, the syringe 400 is moved to the waste port 150 and an injection operation is performed. The syringe 400 draws air and/or base fluid in a previous step, which is discarded.

The steps 11 and 12 are performed for the purpose of exhausting air in the infusion bag 200, and therefore the steps 11 and 12 may be collectively referred to as an exhausting step 10. It is noted that the number of the degassing step 10 is not necessarily one. A preset number of venting steps 10 may be performed during the dispensing process. The specific number of times of the preset number may be set according to the size of the syringe 400 and the condition of air in the infusion bag 200. For example, the preset number may be set to 1 time, 2 times, 3 times, or 4 times.

Since the degassing step 10 is set to be performed earlier and the number of times it is performed is preset, only the saline solution should be present in the infusion bag 200 after the completion of all the degassing steps 10. On the other hand, even if the air in the infusion bag 200 is small and the number of air exhaust steps 10 is large, the arrangement only loses some of the physiological saline in the infusion bag 200 and does not cause the loss of the medicine. After the venting step is completed 10, only the base liquid will be present in the infusion bag 200, ensuring that a sufficient amount of base liquid will be sucked in the subsequent sucking step without sucking air, and further ensuring that the dispensing process can be smoothly performed.

After the above-mentioned air discharging step 10 is completed, the liquid transferring step 20 can be performed. The pipetting step 20 further comprises:

in step 21, the infusion bag 200 is sucked by the suction/injection device 400. Since this step is performed after the degassing step 10, a sufficient amount of the base liquid is sucked in this step without sucking air.

In step 22, the syringe 400 is moved to align with the vial 300 to perform an injection operation on the vial 300, for example, by inserting the needle of the syringe 400 into the vial 30 and then pushing the push rod of the syringe 400. This step allows a sufficient amount of base solution to be injected into vial 300. These base solutions can serve as carriers for the powder in vial 300, allowing the powder to be withdrawn from vial 300 more smoothly in subsequent steps.

In step 23, the syringe 400 is separated from the vial 300. For example, the needle of the syringe is pulled out of vial 30. The purpose of this step is not to damage the syringe 400 during subsequent steps of shaking the vial 300.

In step 24, vial 300 is shaken. The purpose of this step is to allow the base liquid to better carry the powder in vial 300.

After the pipetting step 20 is completed, a drug returning step of returning the powder and the base liquid in the vial 300 to the infusion bag 200 may be performed. This drug returning step 30 further comprises:

in step 31, the vial 300 is sucked by the sucking and injecting device 400. Since penicillin bottle 300 has been shaken, the suction operation performed on penicillin bottle 300 in this step can preferably suck out the base liquid carried by the base liquid together with the base liquid in penicillin bottle 300.

Step 32 is to inject the infusion bag 200 with the syringe 400. Since the powder in the vial 300 has been drawn out into the syringe 400, the dispensing process of the infusion bag 200 can be completed only by injecting the infusion bag 200.

In the dispensing system and the dispensing method provided in this embodiment, since the preset number of air exhausting steps 10 are provided, the air in the infusion bag 200 can be exhausted before the liquid transferring step 20 is performed, so that the subsequent liquid transferring step 20 and the medicine returning step 30 do not fail due to the air in the infusion bag 200, and thus the automated dispensing is realized.

While the dispensing system and method of one embodiment of the present invention are described above, in other embodiments of the present invention, the dispensing system and method may have further details than those described above and at least some of these details may vary widely in many respects. For example, while steps 20 and 30 are described above, in some embodiments, steps 20 and 30 may be performed multiple times. For example, when the size of the syringe 400 is small, the step 20 may be performed several times and then the step 30 may be performed several times. For another example, when it is desired to more thoroughly utilize the powder in vial 300, steps 20 and 30 may be repeated. At least some of these details and variations are described below in several embodiments.

With continued reference to fig. 1 and 2, in some embodiments the infusion bag 200 includes a body 210, a cap 220, and a neck 230. Each infusion bag 200 has two neck portions 230, and a cap 220 is provided at the upper end of each neck portion 230. At least a portion of the cover member 220 is made of an elastic material. This arrangement allows aspiration and infusion of the bag 200 by piercing the cap 220 with a needle. The bag holding member 110 is a horizontally disposed plate and the thickness of the plate corresponds to the neck 230. The bag holding member 110 is provided with two open slots having a size corresponding to the neck 230. Such an arrangement enables the bag holding unit 110 to detachably engage with the neck 230, thereby holding the bag 230.

In some embodiments, the bag holding assembly 110 and the neck 230 are detachably engaged in a manner that: the bag holding member 110 is a plate member having a thickness equal to or slightly less than the length of the neck 230, the width of the open slots is equal to or slightly greater than the diameter of the neck 230, and the distance between the two open slots corresponds to the distance between the two necks 22.

This arrangement allows the neck 230 to engage the open slot, thereby allowing the bag 200 to be held by the bag holding assembly 110. After the neck 230 is engaged with the opening slot, the position of the infusion bag 200 is not easy to move, so that the position of the cover 220 is relatively stable, and the automatic dispensing operation of the dispensing system is facilitated.

In the above step 12, the air and/or the base liquid in the syringe 400 is discarded in such a manner that the syringe 400 is moved to the waste liquid port 150 and the injection operation is performed. This step 12 may further comprise the steps of:

in step 12a, the pipette 400 is moved horizontally into alignment with the waste port 150.

In step 12b, the syringe 400 is vertically moved such that at least a portion of the needle 430 of the syringe 400 enters the waste port 150;

in step 12c, an injection operation is performed, and the air and/or the base liquid in the syringe 400 is discarded;

in step 12d, the syringe 400 is vertically moved such that the needle 430 of the syringe 400 is away from the waste port 150.

The arrangement in step 12 is such that the tip of the needle 430 of the syringe 400 is located in the waste port 150 each time the air and/or base liquid in the syringe 400 is discarded. Therefore, if the base fluid is present in the syringe 400, the base fluid will not spill out when entering the waste port 150, thereby keeping the dispensing system 100 clean.

Referring to fig. 1-3, in some embodiments an infusion bag 200 has two covers 220. In the "step of performing the aspiration operation of the infusion bag 200 with the aspirator 400" and the "step of performing the injection operation of the infusion bag 200 with the aspirator 400", for example, in steps 11, 12, 21, and 32, the needle 430 of the aspirator 400 is inserted into the same cap 220 of the infusion bag 200. Such an arrangement can keep the other cap 220 as clean as possible, and remain ready for use while administering fluid to the patient.

The manner in which vial 300 is held by vial gripping assembly 120 may vary. In some embodiments, vial gripping assembly 120 grips the middle portion of vial 300 and enables rotation of vial 300. Referring to fig. 1, in some embodiments, the way in which the penicillin bottle holding assembly 120 holds the penicillin bottle 300 is: the vial gripping assembly 120 is detachably fixed to the bottom 300 of the vial and the vial gripping assembly 120 is further capable of shaking the vial 300 in a horizontal direction. Such a gripping arrangement requires less precision in the alignment between the gripping assembly 120 and vial 300. On the other hand, in such a holding manner, even if the holding unit 120 is accidentally released due to a failure, the vial 300 does not fall off, and the loss due to the falling and damage of the vial 300 can be reduced.

The specific method of the syringe moving means 130 moving the syringe 400 in the horizontal and vertical directions may be various. In some embodiments, the syringe moving device 130 is a multi-joint robot arm that is movable in horizontal and vertical directions. Referring to fig. 1 and 2, in some embodiments, the dispensing system 100 further includes a horizontal track 160. The syringe moving device 130 cooperates with the horizontal rail 160 such that the syringe moving device 130 can move along the horizontal rail 160. It is noted that although the horizontal rail 160 is described as a "horizontal" rail, it does not mean that the rail must be strictly horizontal, nor that the rail need be linear. For example, in the example shown in fig. 1, the horizontal rail 160 is a circular rail disposed horizontally.

The syringe operating means 140 is provided on the syringe moving means 130 in such a manner that the syringe 400 can be operated for injection and suction by the operation of the syringe operating means 140 regardless of the position to which the syringe moving means 130 is moved.

With continued reference to fig. 1 and 2, in some embodiments, the syringe moving device 130 further includes a horizontal moving assembly 131 and a vertical moving assembly 132. Literally, the horizontal moving assembly 131 allows the pipette 400 to move in the horizontal direction, and the vertical moving assembly 132 functions to allow the pipette 400 to move in the vertical direction. Specifically, the horizontal moving assembly 131 is engaged with the horizontal rail 160 and can move along the horizontal rail 160. The vertical moving assembly 132 is provided on the horizontal moving assembly 131, and thus can be moved horizontally while being carried by the horizontal moving assembly 131. The vertical moving assembly 132 itself is capable of vertical movement relative to the horizontal moving assembly 131. A syringe operator 140 is disposed on the vertical moving assembly 132. This arrangement enables the pipette operating device 140 to be moved in the horizontal and vertical directions by the movement of the horizontal moving assembly 131 and the vertical moving assembly 132.

Referring to fig. 2, in some embodiments, the syringe 400 further includes an outer sleeve 410, a push rod 420, and a needle 430. Wherein the vertical moving assembly 132 is detachably secured with the outer sleeve 410. The syringe operator 140 is removably secured to the push rod 420. The syringe operator 140 is movable in the vertical direction along the vertical movement assembly 132. This arrangement fixes the position of the outer sleeve 410 and the vertical moving assembly 132, so that the syringe operating device 140 can move the push rod 420 up and down by moving up and down along the vertical moving assembly 132 in the vertical direction, so as to enable the syringe 400 to perform the injection and suction operations.

While the invention has been described with reference to a number of specific embodiments, it will be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the invention, and various changes in and substitutions of equivalents may be made without departing from the spirit of the invention. Therefore, changes and modifications to the above-described embodiments within the spirit and scope of the present invention will fall within the scope of the claims of the present application.
