Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to the work of suctioning and collecting a medicinal solution stored in an ampoule into a ring fluid drip bottle containing Ringer's solution, glucose solution, etc., and mixing it. Alternatively, the present invention relates to a liquid medicine collection device that automatically performs an operation for collecting liquid medicine from individual ampoules in order to collect the liquid medicine in the ampoules.

(Prior art) Ringer's solution or glucose solution is often mixed with medicinal solutions such as antibiotics, cardiotonic drugs, vasodilators, vitamins, etc., and administered to patients. Although it is becoming more and more common to mix 10 ampoules of liquid,
Currently, the work of co-injecting a large number of different types of medicinal solutions stored in ampoules is performed manually using a syringe.

In other words, cut the neck of each ampoule one by one, draw out the drug solution with a syringe,
Next, the process of inserting the needle of the syringe into the rubber stopper of the liquid ring bottle and injecting the liquid into the liquid ring bottle is repeated.

In such work, since the liquid ring bottle is sealed, internal pressure is applied during injection, and the injection operation must be performed while removing the air inside the liquid ring bottle.

Therefore, it requires a great deal of effort, skill, and time, and furthermore, the rubber stopper of the liquid ring bottle is punctured multiple times with a syringe needle, resulting in many holes, which may lead to the contamination of bacteria and the risk of the liquid ring bottle being turned upside down when used. There were some inconveniences, such as the liquid sometimes flowing out.

No. 167590, etc., discloses a method in which the needle of a suction tube connected to an aspirator is inserted into a liquid bottle, and the medicinal liquid in the ampoule is sucked and injected into the liquid bottle while reducing the pressure. Only the injection into the bottle is performed automatically using a pump, and the operations of cutting the ampoule and setting the suction tube into the ampoule are still manual operations.

(Problems to be Solved by the Invention) In the conventional method as described above, in order to co-inject medicines in 5 to 10 ampoules, it is necessary to cut open the ampoule neck and set the suction tube for each ampoule. Since the operation is complicated, it takes 3 to 5 minutes for each ampoule, and in the case of a large number of ampules, a large amount of time, considerable effort and skill are required. It was far from it.

In addition, in the case of expensive ampoule liquids, if the ampoule container becomes defective due to defective deformation, etc.
The content liquid is collected and reused, but even in such cases, the above-mentioned problems have conventionally occurred due to manual collection operations.

(Means for Solving the Problems) Therefore, the technical problem of the present invention is to improve the drawbacks of the conventional methods as described above, reduce labor and working time, and eliminate concerns such as bacterial contamination and liquid leakage. The purpose of the present invention is to provide a device for collecting medicinal liquid into a ring-free liquid bottle, etc., and the technical means of the present invention to solve this technical problem is to hold the ampoule so that the neck of the ampoule is in a constant position. a cutter for making a cut into the neck of the ampoule; a means for removing the ampoule from the ampoule holding means; a means for removing the neck of the ampoule from the cut; and a suction for sucking the drug solution from the ampoule from which the neck has been removed by the means. The device comprises a nozzle, a means for inserting and extracting the suction nozzle into the ampoule, a pipe for sending the medicinal solution from the suction nozzle to the collection container, and a pipe means for removing air from the collection container, the neck of the ampoule being The holding means includes a neck holding part consisting of a substantially arcuate fixing part that holds a part of the periphery of the neck of the ampoule, and a pin part connected to the fixing part and always closed and opened with elastic force; This is a liquid medicine collection device that consists of a hanging frame that suspends a neck holding part at a certain height.

(Example) The embodiments shown in the drawings will be described below.

The present invention consists of a means A for holding the ampoule so that the position of the neck of the ampoule is constant, a cutter B for making an incision in the neck of the ampoule, a means C for taking out the ampoule from the ampoule holding means, and a means D for separating the neck from the incision. , a suction nozzle E for sucking the medicinal solution from the ampoule, a vertical movement means F for inserting and extracting the suction nozzle into the ampoule, a pipe for sending the medicinal solution from the suction nozzle to the collection container, and a pipe means G for removing air from the collection container. ing.

Therefore, a description will be given of means A for holding the ampoule so that the position of the neck of the ampoule remains constant.

1 is an ampoule hanging device, as shown in Figure 4.
Between the hanging fixing part 1a and the base 1b are the side plates 1c, 1.
They are connected by c. The suspension fixing part 1a has a retaining screw 2, which is adapted to horizontally hold a clamping pin 3 having an ampoule neck clamping part at its tip. The clamping pin 3 is normally closed and is designed to open with elastic force (see FIG. 4).

The above constitutes a frame that suspends the ampoule neck holding part at a certain height.

The base 1b also has a sawtooth cutout 4 for feeding.

According to this ampoule hanger, the neck of the ampoule can be held between the clamping pins 3 and suspended, and the ampoule can be easily removed from the clamping pin by sliding the ampoule in the horizontal direction with a chuck which will be described later. As a result, each large and small ampoule is held at the neck position of the ampoule by the clamping pin 3, so that the neck position of the ampoule can be aligned at a fixed position, and the cutter described later will automatically hit the neck. Become.

Next, the cutter B that makes a cut into the neck of the ampoule will be explained.

5, 5a are side guides on the base plate 9,
This guides the base 1b of the ampoule hanging tool (see Figure 1).

Reference numeral 6 denotes a support post protruding from the base plate 9, and an arm 8 having a cutter 7 on the top thereof moves left and right.

Therefore, the ampoule hanger 1 is the feeding device 4a.
When the ampoule is conveyed to the position of the cutter 7 and held by a chuck, which will be described later, a cut is made in the neck of the ampoule with the cutter. The cutter can be a diamond cutter with a diamond attached to a disk, a knife cutter, a laser beam, a microwave, or a heated nichrome wire, etc., to make an incision in the neck of the ampoule. According to current ampoules, it is not necessary to make a cut.

Next, the arms 10, 10 with chucks for clamping and fixing the body of the ampoule that is latched to the above-mentioned ampoule hanging tool will be explained.
is an arm that slides along guide grooves 11, 11 on the base plate 9, and has bars 12, 1 at its upper end.
The ampoule of the hanging tool is clamped and fixed by the chucks 13, 13 at the two ends, and when the ampoule is clamped from the left and right with the chucks in conjunction with the ampoule hanging tool 1 through a mechanism not shown, the cutter is activated.

When a cut is made in the ampoule by the cutter 7, the lifting device 1 is moved to the next feeding device 14 by the feeding device 4a.
will be taken over.

The sling 1 is conveyed by the feeding device 14 to a position where the neck of the ampoule is cut off.

Therefore, the means C for taking out the ampoule from the ampoule holding means is activated by detecting the ampoule with the sensor 15a.
It moves left and right in a direction perpendicular to the direction of movement of the ampoule hanger 1, and has a swinging fulcrum 1 at the lower end.
When the movable table 15 retreats and hits the stopper 19, the pin 20 hits the rear end of the slit groove 21 and tilts forward (see FIG. 8).

The moving table 15 is moved forward and backward by screwing the feed screw 17 and the female screw 18 together as shown in FIG.

At the upper end of the movable table 15 there are chucks 22, 23 that hold the ampoule from the left and right sides, and the chucks 22, 23 are opened and closed by the rotation of a pinion 24 via racks 25, 26 that mesh with the chucks. The bar 27 of the chuck 22 is always elastically supported by a spring 28 to prevent the ampoule from being damaged by the chuck.

Reference numeral 29 denotes a spring for cushioning the impact when the movable table 15 comes into contact with the stopper 19.

In any case, when the sensor 15a detects the ampoule whose neck should be cut off, the chucks 22, 23
works to clamp the ampoule. When the ampoule is clamped by the chucks 22, 23, the movable table 15 is moved back to take out the ampoule from the ampoule hanger 1, and then the means D for separating the neck from the incision is activated.

Reference numeral 30 shown in FIG. 1 is the ampoule neck cutting bar, which rotates around the support 31, hits the neck of the ampoule, and cuts the neck into a dust (not shown) cut below the base plate 9. .

The means for cutting off the ampoule is not limited to the above-described method of hitting and cutting off the notched neck.

For example, as in the embodiment shown in FIG. 9, a gripper 40 that can be opened freely grips the head of the ampoule, and while pulling the gripper 40 upward while holding the ampoule, the outer circumference is There is also a method of interlocking the support arm 41 that applies a rotational bending motion to the side, and bending and separating the neck part with an action similar to a hand-folding action.

That is, as shown in FIG. 9, a pincer-shaped gripping tool 40 that opens and closes around a fulcrum 48 by an appropriate opening/closing means is configured so that it can reciprocate in the direction of the arrow by a cylinder mechanism, and the vertical movement of this gripping tool 40 On the other hand, the support arm 41 is also moved up and down by the springs 44 and 45, and an appropriate bending means is applied to this so that the support arm 41 is bent in the direction of the arrow about the fulcrum 43. Then, the ampoule head gripped by the chuck 42 is bent and separated by the gripper 40. Note that 46 indicates the rubber of the gripping tool 40.

In this case, the cutter part that makes an incision in the neck of the ampoule and the cutting means are not installed in different positions, but the gripping tool is installed above the same position as the cutter part for bending and cutting. 42 is a chuck that clamps the body of the ampoule to fix the ampoule and keep it in a stable state when it is separated, and the bar 12 and chuck 13 shown in FIG.
It is similar to

Next, the moving table 15 retreats.

When the movable table 15 moves backward and hits the stopper 19, the ampoule tilts forward about the fulcrum 16.

Next, the suction nozzle E and the vertical movement means F for inserting and extracting the suction nozzle into and out of the ampoule will be explained. Reference numeral 32 shown in FIG. has been done. The nozzle guide 33 is supported by a nozzle holder 34, and the nozzle holder 34 is moved up and down by the operation of a cylinder 35.

Next, a description will be given of the pipe that sends the medicinal solution from the suction nozzle to the collection container, and the pipe means G that removes the air in the collection container. The bottle 38 is connected to a suction pump or a tubing pump (liquid feeding pump) through a pipe 39.

Therefore, when the moving table 15 is tilted forward, the ampoule supported by the chucks 22 and 23 is tilted forward, and the suction nozzle 32 is inserted into the cut end by the actuation of the cylinder 35.

When the suction nozzle 32 is inserted into the ampoule, the suction pump and the tubing pump are activated to inject the medicinal liquid in the ampoule into the ring liquid bottle 38.

In addition, when injecting the medicinal liquid in the ampoule into the ring liquid bottle 38, there is also a method of feeding it by pressurization, which does not require removing the air from the bottle. In this case, the nozzle 32 for sucking the ampoule liquid is inserted obliquely with respect to the ampoule, so that the medicinal liquid in the ampoule can be completely sucked up.

In other words, the bottom of the ampoule is generally high at the center, and if the nozzle is placed in the center, it will not be possible to remove the liquid completely.

However, the suction nozzle itself may be tilted without tilting the ampoule chuck.

Next, the ampoule from which the chemical solution has been sucked out falls when the chucks 22 and 23 are opened and is thrown into the dust.Then, the moving table 15 moves forward, and the sensor confirms that the next ampoule is in the fixed position. Then, the chucks 22 and 23 are closed again, and the operation described above is performed.

In this way, the ampoule suspended from the hanging device 1 passes through each of the above-mentioned means sequentially, and the medicinal solution is injected into the ring liquid bottle, and all the ampules suspended from the hanging device perform the above operations. When this is received, the hanging device 1 is moved to the discharge position by the feeding devices 49, 50, and 51, and when the new hanging device with the ampoule suspended is set in the state shown in Fig. 1, the same operation is repeated again. It is.

It should be noted that the feeding devices 49, 50, 51, like the feeding devices 4a, 14 described above, perform parallelogram motion and are advanced by engagement of their saw teeth with the saw teeth of the hanger.

(Effect of the invention) According to this technical means, the work of suctioning and collecting the medicinal solution stored in the ampoule into a drip bottle containing Ringer's solution or glucose solution, etc., and mixing it, or the medicinal solution in the ampoule The feature is that the work to collect the drug solution from individual ampoules can be performed automatically, which reduces labor and work time and eliminates concerns such as contamination with bacteria and liquid leakage. A device for collecting medicinal liquid into a liquid bottle or the like can be obtained.

In particular, the means for holding the neck of the ampoule consists of a substantially arcuate fixing part that clamps around a part of the neck of the ampoule, and a pin part that is connected to the fixing part and always closes and opens with elastic force. It consists of a neck clamping part and a hanging frame that suspends the neck clamping part at a certain height, so the ampoule can be suspended by pinching the neck part with pins, and the ampoule can be slid horizontally. Therefore, the ampoule can be easily removed from the pin, and each large and small ampoule is held at the neck position by a holding pin.
The neck of the ampoule can be aligned at a fixed position, and the cutter can be automatically applied to the neck. Therefore, it is also possible to handle a mixture of large and small ampoules.
