Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a medicine bottle module that connects with a syringe for dispensing medicine. Background Technology

[0002] In the medical field, it is often necessary to mix medications in vials with other solutions for pre-injection preparation. Currently, the process for mixing medications in vials involves: medical staff opening a pre-purchased medication transfer device on-site; manually installing the device onto the vial by piercing the stopper; connecting the vial to the device; connecting a pre-filled syringe to the device and injecting the solution into the vial; and finally, using the syringe to extract the mixed solution. However, this on-site assembly of the medication transfer device and vial not only consumes considerable preparation time for medical staff but also easily leads to problems such as incompatibility, resulting in installation failures or insecure installation, causing unnecessary waste (e.g., wasted equipment costs due to replacement of the transfer device, wasted time on reassembly, and wasted medication due to vial detachment). Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a medicine bottle module that connects with a syringe for dispensing medicine. It pre-assembles the medicine bottle and the medicine transfer device together to reduce the operation steps of medical staff when dispensing medicine on site. It not only eliminates the risk of incorrect assembly, but also saves time and effectively improves the reliability and efficiency of medicine dispensing.

[0004] To achieve the above and other related objectives, this utility model provides a vial module for dispensing medication via a syringe, comprising a pre-assembled vial and a medication transfer device. The medication transfer device includes a vial connecting shell and a puncture device, the puncture device being slidably disposed within the vial connecting shell along its own axial direction. The vial connecting shell is fixed to the vial, and the puncture device is used for docking and communication with the syringe. A protective mechanism is provided between the puncture device and the vial connecting shell to prevent the puncture device from unintentionally switching from a non-puncture state to a puncture state. This application pre-assembles the vial and medication transfer device together before leaving the factory, which not only simplifies the on-site medication dispensing operation steps for medical personnel but also avoids the risk of incorrect assembly by medical personnel, improving the reliability and efficiency of on-site medication dispensing. The protective mechanism effectively prevents the vial module from accidentally puncturing the vial during transportation or medication preparation, improving medication safety and reducing waste costs.

[0005] Preferably, the protective mechanism includes an elastic claw on the puncture device and a stop on the vial connecting shell; the elastic claw and the stop cooperate to restrict the puncture device from moving accidentally toward the vial, so as to prevent the puncture device from accidentally puncturing the vial cap under a small external force, thereby improving medication safety.

[0006] Preferably, the protective mechanism includes a radial protrusion detachably mounted on the puncture device, and the vial connecting shell is provided with a limiting hole that mates with the radial protrusion; the axial movement of the puncture device is restricted by the mate between the radial protrusion and the limiting hole, thereby preventing the puncture device from piercing the vial or completely detaching from the vial connecting shell during transportation or drug preparation.

[0007] Preferably, the puncture device includes a puncture needle, a syringe connector coaxially connected to the puncture needle, and an annular sliding portion located outside the syringe connector; the annular sliding portion is located between the medicine bottle and the stop; the stop restricts the maximum stroke position of the annular sliding portion to prevent the puncture device from detaching from the medicine bottle connector shell.

[0008] Preferably, the outer periphery of the annular sliding part is evenly distributed with multiple axial grooves, and the medicine bottle connecting shell is provided with an axial slider that slides in cooperation with each axial groove to ensure the stability of the axial sliding of the puncture device.

[0009] Preferably, the axial slider abuts against the cap of the medicine bottle to avoid the problem of the medicine bottle shaking during installation.

[0010] Preferably, the axial groove and the elastic claw are arranged alternately in the circumferential direction of the annular sliding part to ensure that the elastic claw has sufficient deformation space.

[0011] Preferably, the medicine bottle connecting shell has multiple expansion grooves evenly distributed circumferentially, and an elastic arm is formed between two adjacent expansion grooves; the elastic arm is provided with an inverted buckle; in this way, the elastic arm can be used to elastically reset so that the inverted buckle can hold the medicine bottle, thereby achieving the clamping and fixing of the medicine bottle.

[0012] Preferably, the medicine bottle connecting shell and the medicine bottle are threaded together.

[0013] Preferably, the outer wall of the puncture needle near the puncture end is provided with a drainage port that communicates with the inside of the puncture needle, so that when the medicine bottle is inverted, the residual liquid below the puncture end can flow out through the drainage port, avoiding waste of medicine.

[0014] As described above, the medicine bottle module of this utility model that connects with a syringe for dispensing medicine has the following beneficial effects:

[0015] 1) This utility model pre-assembles the medicine bottle and the medicine transfer device together to form a medicine bottle module that can be used "out of the bag". This not only avoids the risk of incorrect assembly due to non-standard operation or model mismatch during on-site assembly, but also simplifies the operation steps of on-site medicine preparation and improves the reliability and efficiency of on-site medicine preparation.

[0016] 2) The drug transfer device of this utility model includes a drug connection shell and a slidably disposed puncture device, and a protective mechanism is added between the drug connection shell and the puncture device to prevent the puncture device from accidentally moving towards the drug bottle under a small external force to puncture the bottle cap, thereby ensuring the safety of the drug in the drug bottle module during the transfer or preparation of the drug, and avoiding additional cost waste.

Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0027] Please see Figures 1 to 7 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0028] Example 1:

[0029] like Figures 1 to 3 As shown, this embodiment provides a vial module that docks with a syringe. The vial module includes a vial 1 pre-assembled at the factory and a liquid transfer device. The liquid transfer device includes a vial connecting shell 2 and a puncture device 3 slidably disposed in the vial connecting shell 2 along its own axial direction. The vial connecting shell 2 is fixedly installed on the vial 1, and the puncture device 3 is used to dock and communicate with an external syringe (not shown in the figure). In this way, after the puncture device 3 punctures the cap of the vial 1, the liquid medicine in the syringe can be introduced into the vial 1 for mixing and preparation.

[0030] It is understood that the connection between the medicine bottle connecting shell 2 and the medicine bottle 1 can be in the following forms, including but not limited to:

[0031] Connection type 1:

[0032] The medicine bottle connecting shell 2 is threadedly connected to the medicine bottle 1.

[0033] Connection type two:

[0034] The medicine bottle connecting shell 2 is snapped and fixed onto the medicine bottle 1. At this time, the medicine bottle 1 is a vial or a similar structure.

[0035] Specifically, such as Figure 2 and Figure 6As shown, the outer wall of the lower part of the medicine bottle connecting shell 2 has multiple expansion grooves 22 evenly distributed circumferentially, and there is an elastic arm 23 between two adjacent expansion grooves 22. The elastic arm 23 is provided with an inverted buckle 24. When the mouth of the medicine bottle 1 is inserted into the medicine bottle connecting shell 2, the medicine bottle 1 will squeeze the inverted buckle 24 on the elastic arm 23, causing the elastic arm 23 to bend and deform so that the inverted buckle 24 deflects away from the axis of the puncture device. When the inverted buckle 24 passes the mouth of the medicine bottle 1 and reaches the neck, the elastic arm 23 will automatically reset so that the inverted buckle 24 is engaged at the neck of the medicine bottle 1, thus completing the clamping and fixing of the medicine bottle 1.

[0036] The structure of puncture device 3 is as follows Figure 2 and Figure 3 As shown, it includes a coaxially arranged puncture needle 31, syringe connector 33, and annular sliding part 32; wherein, the syringe connector 33 is coaxially connected with the puncture needle 31; the annular sliding part 32 is located outside the syringe connector 33 and slides in axial direction with the medicine bottle connecting shell 2; when the puncture needle 31 of the puncturist 3 punctures the cap of the medicine bottle 1, the annular sliding part 32 is used to contact and abut against the cap of the medicine bottle 1, so as to control the puncture depth of the puncture needle 31.

[0037] It should be noted that the syringe connector 33 is a Luer connector or other connector, and there are no restrictions on which one is used, as long as it can be connected to an external syringe.

[0038] like Figure 4 As shown, the puncture needle 31 has a drainage port 311 on the outer wall near the puncture end, which is connected to the inside of the puncture needle. In this way, when the puncture needle 31 is inserted into the medicine bottle 1, the medicine bottle module can be inverted to allow the residual liquid below the level of the medicine bottle 1 to flow out through the drainage port 311, thus avoiding the waste of medicine.

[0039] To ensure the sliding stability of the puncture device 3, such as Figure 4 and Figure 6 As shown, the annular sliding part 32 has a plurality of axial grooves 321 evenly distributed on its outer periphery, and the medicine bottle connecting shell 2 is provided with an axial slider 25 that slides in cooperation with each axial groove 321; in this embodiment, as Figure 2 As shown, the axial slider 25 abuts against the cap of the medicine bottle 1, which not only prevents the medicine bottle 1 from being over-installed, but also prevents the medicine bottle 1 from shaking after installation, ensuring installation stability.

[0040] In addition, to prevent the puncture device 3 from accidentally puncturing the bottle cap during transportation or preparation of the medicine bottle module due to vibration or shaking, which would render the medicine bottle module unusable, this application adds a protective mechanism between the medicine bottle connecting shell 2 and the puncture device 3. This protective mechanism prevents the puncture device 3 from unintentionally switching from a non-puncture state to a puncture state.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, the protective mechanism includes an elastic claw 34 located on the annular sliding part 32 and a stop 21 located on the medicine bottle connecting shell 2. In the initial state, the elastic claw 34 and the stop 21 cooperate to restrict the puncturist 3 from moving accidentally towards the medicine bottle 1 under a small external force, thereby preventing the cap of the medicine bottle 1 from being punctured unintentionally. When it is necessary to puncture the cap of the medicine bottle 1, it is only necessary to deform the elastic claw 34 inward to disengage from the stop 21 and move the puncturist 3 towards the medicine bottle 1.

[0042] It is understood that there can be one or more elastic claws 34, and there is no limitation on this; when there are multiple elastic claws 34, the multiple elastic claws 34 are evenly distributed circumferentially on the top of the annular sliding part 32.

[0043] In a preferred embodiment, such as Figure 4 As shown, the elastic claws 34 and axial grooves 321 are arranged alternately in the circumferential direction of the annular sliding part 32 to ensure that the elastic claws 34 have sufficient deformation space.

[0044] like Figure 4 and Figure 5 As shown, the elastic claw 34 includes a cantilever portion 341 and a claw portion 342; wherein, the claw portion 342 includes a stopped surface 3421 that cooperates with the stop member 21, and the stopped surface 3421 is a horizontal surface or an inclined surface; in this embodiment, the stopped surface 3421 is preferably an inclined surface, so that as long as the puncture device 3 is pressed with a large external force, the stopped surface 3421 of the claw portion 342 will rotate towards the axis of the puncture device under the stopping action of the stop member 21, so that the claw portion 342 can smoothly pass over the stop member 21 and complete the subsequent puncture action.

[0045] Furthermore, such as Figure 5 As shown, the claw portion 342 includes a guide surface 3422, which is an inclined surface. Thus, when the puncture device 3 is installed in the vial connecting shell 2 from bottom to top, the stop member 21 will contact and squeeze the guide surface 3422 of the claw portion 342, so that the claw portion 342 rotates in a direction closer to the axis of the puncture device, thereby allowing the claw portion 342 to smoothly pass over the stop member 21 and complete the locking of the claw portion 342 and the stop member 21.

[0046] In addition, such as Figure 2 As shown, in the initial state, the top of the annular sliding part 32 abuts against the stop 21. In this way, the stop 21 can be used to limit the maximum travel position of the annular sliding part 32, so as to prevent the puncture device 3 from accidentally detaching from the medicine bottle connecting shell 2 during transportation or drug preparation.

[0047] Of course, a cover can also be added to the medicine bottle connecting shell 2 to cover the syringe connector 33, so as to limit the maximum travel position of the puncture device 3.

[0048] Example 2:

[0049] The main difference between this embodiment and Embodiment 1 lies in the specific structure of the protection mechanism.

[0050] In this embodiment, the protective mechanism includes an elastic claw 34 located on the annular sliding part 32, and a groove on the medicine bottle connecting shell 2 that cooperates with the elastic claw 34; the axial position of the puncturist 3 is restricted by the cooperation of the elastic claw 34 and the groove, so as to avoid the situation where the puncturist 3 accidentally punctures the medicine bottle cap during the transportation or preparation of medicine.

[0051] When the puncture device 3 needs to puncture the medicine bottle 1, simply press the elastic claw 34 at the slot to make the elastic claw 34 deflect inward and disengage from the corresponding slot, and push the puncture device 3 to move closer to the medicine bottle 1.

[0052] Example 3:

[0053] The main difference between this embodiment and Embodiment 1 lies in the specific structure of the protection mechanism.

[0054] like Figure 7 As shown, the protective mechanism of this embodiment includes a radial protrusion 4 that is detachably mounted on the annular sliding part 32 by means of threaded connection, snap-fit ​​connection, etc. The medicine bottle connecting shell 2 is provided with a limiting hole that cooperates with the radial protrusion 4. The axial position of the puncturist 3 is limited by the cooperation of the radial protrusion 4 and the limiting hole, so as to prevent the puncturist 3 from puncturing the medicine bottle cap during the transportation or preparation of medicine.

[0055] When it is necessary for the puncturer 3 to puncture the medicine bottle 1, simply remove the radial protrusion 4 and push the puncturer 3 towards the medicine bottle 1.

[0056] In summary, this application pre-assembles the medicine bottle 1 and the medicine transfer device together before leaving the factory to form a "ready-to-use" medicine bottle module, effectively avoiding the risk of incorrect assembly due to model mismatch during on-site assembly, and improving the reliability and efficiency of on-site drug dispensing. In addition, the medicine transfer device of this application maintains the state between the medicine connection shell 2 and the puncture device 3 through a protective mechanism, so as to avoid the situation where the puncture device 3 accidentally punctures the medicine bottle cap during the transfer or drug preparation process, thus ensuring the safety of drug use.

[0057] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
