Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to a high-efficiency medicine dispensing device. Background Art
[0002] Intravenous infusion is widely used as the main treatment method in clinical practice, so the preparation of medicine before intravenous administration is also a key task before infusion. At present, the traditional method of preparing medicine uses a syringe, usually injecting the solution in the infusion bag or bottle into the powder injection bottle through a syringe, shaking and vibrating to completely dissolve it evenly, and then withdrawing it with a syringe and injecting it into the infusion bag or bottle. This method requires repeated punctures, and the needle is repeatedly exposed to the outside air, which pollutes the operation of the liquid medicine in the bottle and causes needlestick injuries, and there is a phenomenon of insufficient drug transfer and waste of drugs. In addition, when the liquid medicine is currently configured, the needle of the syringe needs to be inserted into the liquid medicine to be added, and then the liquid medicine is extracted, and then the needle of the syringe is inserted into the infusion bag or infusion bottle, and finally the liquid medicine in the syringe is injected into the infusion bag or infusion bottle, and the needle of the syringe is pulled out to complete the configuration of a liquid medicine. When multiple liquid medicines need to be configured, the above operation can be repeated. Its disadvantage is that the workload of nurses is large, repeated operations cannot avoid the occurrence of contamination.
[0003] At present, other liquid preparation technologies are also used. Such technologies use one pipeline for both liquid discharge and liquid inlet, which inevitably leads to problems such as blockage, pollution, low efficiency, drug waste, and limited scope of use. Moreover, for the preparation of the above two different preparations, except for the use of syringes, the existing technologies have a single function and effect, and are not applicable to the preparation of the above two different preparations and soft bottles, glass bottles, and bagged solvents (such as saline). Such technologies, especially for poorly soluble powders, inevitably require long-term rapid shaking or vibration. Summary of the invention
[0004] The purpose of the utility model is to provide a multifunctional and efficient medicine dispensing device with a simple and reasonable structure, simple process and easy manufacturing, simple operation, using a one-way solvent liquid medicine transfer pipeline and a one-way mixed medicine special pipeline for dissolving and dispensing medicines, convenient to use, efficient, avoiding pollution, reducing waste, suitable for preparing medicines in various containers, and particularly suitable for dissolving and transporting poorly soluble powders without changing the connection and operation mode. The device has a particularly good technical effect, and can transfer liquid medicines to infusion bottles or bags without changing the puncture connection mode, and can also transfer solvent-dissolved powders from infusion bottles and then transfer them to infusion bottles or bags. In order to solve these problems in the prior art, the technical solution provided by the utility model is: an efficient medicine dispensing device, including a first puncture device and a second puncture device, characterized in that: two medicine transfer pipelines, a first medicine transfer pipeline and a second medicine transfer pipeline, are provided between the first puncture device and the second puncture device, and the first medicine transfer pipeline and / or the second medicine transfer pipeline are provided with a check valve.
[0005] In a preferred implementation state, the first puncture device and the second puncture device are provided with a first pipeline opening and a second pipeline opening; the first pipeline opening of the first puncture device and the first pipeline opening of the second puncture device are located at two ends of the first liquid medicine transport pipeline; the second pipeline opening of the first puncture device and the second pipeline opening of the second puncture device are respectively located at two ends of the second liquid medicine transport pipeline.
[0006] In a preferred implementation state, the drug liquid transport pipeline with two check valves connected in series leads to the extraction device interface and / or the extraction device; or leads to the syringe or the extrusion balloon.
[0007] In a preferred implementation state, the first puncture device and the second puncture device are connected by a plastic tube.
[0008] In a preferred implementation state, the first puncture device and the second puncture device are located at two ends of the puncture seat.
[0009] In a preferred implementation state, the first puncture device and the second puncture device are equipped with a plastic puncture needle and / or a stainless steel puncture needle.
[0010] In a preferred implementation state, the first pipeline opening and the second pipeline opening are side holes.

[0012] In a preferred implementation state, a filter is provided in the first drug liquid transport pipeline and / or the second drug liquid transport pipeline.
[0013] In a preferred implementation state, the puncture seat is provided with a filter membrane, a check valve and an injection device interface.
[0014] Compared with the solutions in the prior art, the advantages of the present invention are:
[0015] 1. The utility model uses independent solvent one-way transfer pipelines and independent drug transfer pipeline technologies to achieve efficient circulation of drug solution transportation, avoiding drug waste and pollution.
[0016] 2. The utility model sets up an independent medicine transfer pipeline with a filter, so that the medicine entering the infusion bottle or bag can be filtered in one direction without bidirectional medicine passing through the filter, thus preventing the filtered particles from entering the infusion bottle or bag again.
[0017] 3. When the independent solvent transfer pipeline of the utility model is in use, the solvent directly enters the powder injection bottle to dissolve the powder without passing through a filter, and the air or dissolved medicine in the powder injection bottle enters the solvent bottle or bag through the medicine transfer pipeline, forming a closed loop that can quickly dissolve the powder and transfer the solvent solution to the solvent bottle or bag.
[0018] 4. The powder injection bottle can be completely dissolved without vibration or shaking during the powder dissolution process. Since the technology of the utility model can form a continuous pulse flushing convection effect, it can achieve a particularly good technical effect for the dissolution of poorly soluble powders without changing the equipment or connection method and technique.
[0019] 5. Liquid medicine can be transferred to an infusion bottle or bag, or the liquid medicine dissolved in the powder by the transfer solvent in the infusion bottle can be transferred to the infusion bottle or bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1: See attached Figure 1 As shown:
[0029] A high-efficiency medicine dispensing device comprises a first puncture device 1 and a second puncture device 7. The first drug liquid transport pipeline 2 and the second drug liquid transport pipeline 5 are respectively provided with a check valve 3-1 and a check valve 3-2; a filter 6 is connected in the second drug liquid transport pipeline 5, and the first puncture device 1, the second puncture device 7, the filter 6 and the check valve 3-1 and the check valve 3-2 are connected in series by a plastic pipeline.
[0030] In clinical use, the first puncture device 1 is inserted into a solvent (such as saline) soft bottle or bag, and the second puncture device 7 is inserted into a powder injection (such as penicillin) bottle. The saline bottle is located above the penicillin bottle, and the saline bottle or bag is tilted or inverted. The saline bottle or bag is squeezed by hand, and the saline is pressurized to enter the penicillin bottle through the first puncture device 1, the first drug liquid transport pipeline 2 plastic pipeline, and the second puncture device 7. At the same time, the pressure of the penicillin bottle increases, and the air or / and drug solution in its inner cavity enters the saline bottle or bag through the second drug liquid transport pipeline 5 through the filter 6. Then the saline bottle or bag is released, and the air or / and drug solution in the penicillin bottle further enters the saline bottle or bag through the second drug liquid transport pipeline 5 through the filter 6. In this way, a closed cycle is formed. Repeated squeezing and loosening can completely dissolve the powder drug. Then the penicillin bottle is placed above the saline bottle and tilted or inverted. The saline bottle or bag can be squeezed to completely transfer the drug in the penicillin bottle to the saline bottle or bag.
[0031] Since there are two reverse independent one-way inlet and outlet pipes, the resistance in actual use will be reduced by half compared with other dispensers using filters, which is very convenient for nurses to operate.
[0032] The direction of the drug liquid transport pipeline where the filter is located is to flow toward the solvent bottle (such as a saline bottle), so the filter 6 in this example can also be connected in series in the first drug liquid transport pipeline 2, and the flow direction is toward the solvent bottle, so that the drug liquid entering the solvent bottle can be completely filtered through the filter 6 in one direction.
[0033] This example can also be directly used for transferring liquid medicines that do not need to be dissolved. For example, first pierce the first puncture device 1 into a solvent (such as saline) bottle, and then place the second puncture device 7 into the liquid medicine to be added, such as an ampoule bottle or a liquid medicine packaging bag. The saline bottle is placed vertically and squeezed. The air in the saline bottle is discharged through the first liquid medicine transfer pipeline 2. Since the saline bottle is under negative pressure at this time, the liquid medicine can pass through the second liquid medicine transfer pipeline 5 and the filter 6 into the saline bottle to complete the liquid preparation.
[0034] In this example, the drug liquid transport channels at both ends of the first drug liquid transport pipeline 2 and the second drug liquid transport pipeline 5 leading to the first puncture device 1 and the second puncture device 7 can be independent of each other or shared drug liquid transport channels, that is, the openings of the first puncture device 1 and the second puncture device 7 can be one or two.
[0035] Embodiment 2: See attached Figure 2 As shown:
[0036] An efficient medicine dispensing device Figure 1 , including a first puncture device 1 and a second puncture device 7. The first drug liquid transport pipeline 2 is provided with two check valves, and the drug liquid transport pipeline between the two check valves is connected to the extraction device interface 4; the first drug liquid transport pipeline 2 and the second drug liquid transport pipeline 5 are connected in series with various accessories by plastic pipes.
[0037] In clinical use, the first puncture device 1 is inserted into a solvent (such as saline) bottle or bag, and the second puncture device 7 is inserted into a powder injection (such as penicillin) bottle. The syringe is connected to the extraction device interface 4 to form a closed space. The saline bottle or bag is placed above the penicillin bottle and tilted or hung upside down, and the syringe is sucked. The check valve 3-1 in the first liquid medicine transport pipeline is opened and the check valve 3-2 is closed. The saline liquid is drawn from the saline bottle or bag through the first puncture device 1, the plastic pipeline of the first liquid medicine transport pipeline 2, and the check valve 3-1 into the syringe. Pushing the syringe again can close the check valve 3-1 and open the check valve 3-2. The saline passes through the plastic pipeline of the first liquid medicine transport pipeline 2, the check valve 3-2, and the second puncture device 7 into the penicillin bottle. Since the syringe sucks the saline in one direction, the pressure in the saline bottle or bag is reduced or The penicillin bottle presents negative pressure, and the pressure in the penicillin bottle increases due to the entry of saline, forcing the air and / or liquid medicine in the penicillin bottle to enter the second puncture device 7 and the second liquid medicine transport pipeline 5 plastic pipeline through the first puncture device 1 into the saline bottle or bag. In this way, the penicillin powder in the penicillin bottle can be completely dissolved without residue under the continuous flushing of saline, and the dissolved liquid medicine can be transferred to the saline bottle. Finally, the penicillin bottle is placed on the saline bottle or bag or the saline bottle is upright, and the penicillin bottle solution can be completely transferred by pulling out the push injection syringe, and then the dispenser is removed, and the whole dispensing process is completed.
[0038] The above two check valves can also be set in reverse, that is, the operation process is that the syringe draws air from the penicillin bottle and enters the syringe through the first liquid medicine transport pipeline 2. Due to the negative pressure in the penicillin bottle, saline also enters the penicillin bottle along the second liquid medicine transport pipeline 5. The syringe is pushed, and the air inside it can enter the saline bottle or bag. Repeated operations form a circulating liquid circuit between the syringe, the first liquid medicine transport pipeline 2 and the second liquid medicine transport pipeline 5. The powder in the penicillin bottle is quickly dissolved and moved to the saline bottle or bag under the continuous pulse flushing of the saline, which is particularly suitable for the transportation of poorly soluble powders. At the same time, the liquid medicine can also be directly sucked, and the first puncture device 1 is directly placed in the liquid medicine bottle, and the saline is placed vertically. Pulling the syringe can make the liquid medicine enter the saline bottle or bag along the first liquid medicine transport pipeline 2. This operation can be performed without removing the saline bottle or bag puncture needle, which is convenient and efficient.
[0039] In this example, the two check valves and the extraction device interface 4 can also be integrated into one component.
[0040] The dispenser in this embodiment is suitable for the preparation of various powders and liquids, and is also suitable for solvent bottles and bags of various materials, such as hard plastic bottles, soft bags and glass bottles and other infusion bags. In this example, since this technology can form continuous flushing convection, it is particularly effective for poorly soluble powders without the need to shake or vibrate the powder injection bottle.
[0041] Embodiment 3: See attached Figure 3 , 4 As shown:
[0042] The rest of this embodiment is the same as the second embodiment, except that the first puncture device and the second puncture device 7 are respectively provided with a first pipeline opening and a second pipeline opening, and the first pipeline opening of the first puncture device 1 and the first pipeline opening of the second puncture device 7 are located at two ends of the first drug liquid transport pipeline 2; the second pipeline opening of the first puncture device 1 and the second pipeline opening of the second puncture device 7 are respectively located at two ends of the second drug liquid transport pipeline 5; and a filter 6 is serially connected in the plastic pipeline of the second drug liquid transport pipeline 5.
[0043] In clinical use, the first puncture device 1 is inserted into the solvent bottle or bag, the second puncture device 7 is inserted into the powder injection bottle, and the syringe is connected to the extraction device interface 4 to form a closed space. Since the first liquid medicine transport pipeline 2 is a one-way pipeline, the second liquid medicine transport pipeline 5 is also a one-way pipeline in actual use. Therefore, the solution entering the solvent bottle or bag passes through the filter 6 in one direction into the saline, and there is no existing technology in which the inlet and outlet liquids pass through the filter so that the filtered particles enter the solvent bottle or bag again.
[0044] Since there are two independent one-way inlet and outlet pipes, the resistance in actual use will be reduced by half compared with other dispensers using filters, which is very convenient for nurses to use.
[0045] The direction of the drug liquid transport pipeline where the filter is located is toward the solvent bottle (such as a saline bottle), so the filter 6 in this example can also be set in the first drug liquid transport pipeline 2, and then the flow direction of the first drug liquid transport pipeline 2 is set to flow toward the solvent bottle (such as a saline bottle).
[0046] This example is also applicable to the preparation of liquid medicine, please refer to Example 2 for details.
[0047] Embodiment 4: See attached Figure 5 As shown:
[0048] The rest of this embodiment is the same as the second and third embodiments, except that a filter 6 is connected in series in the plastic pipeline of the second liquid medicine transport pipeline 5, and the extraction device interface 4 connected between the two check valves in the plastic pipeline of the first liquid medicine transport pipeline 2 is replaced with an extrusion balloon 8.
[0049] In actual use, the trocar is connected to the corresponding bottle body, and the balloon 8 is directly and continuously squeezed to prepare the liquid medicine for transportation. For other operations, refer to the second and third embodiments.
[0050] Embodiment 5: See attached Figure 6 As shown:
[0051] In this example, the first puncture device 1 and the second puncture device 7 are connected to the two ends of the puncture seat. A filter membrane, a check valve, and two liquid medicine transport pipelines are arranged in the puncture seat. The extraction device interface 4 is located between the first puncture device 1 and the second puncture device 7.
[0052] In this example, the drug liquid transport pipeline between the two check valves can be connected to the extraction device interface 4; or the extraction device interface 4 can be directly connected to or replaced with a syringe or an extrusion balloon 8, or a plastic hose can be used to connect the puncture seat and the extraction device interface 4 or the extraction device.
[0053] For usage, technical effects and other references, refer to Examples 2, 3 and 4.
