Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a quantitative drug dispensing device for intravenous preparation. Background Technology
[0002] Intravenous drug preparation is a crucial part of clinical treatment, especially in hospital intravenous drug preparation centers, where large-scale, high-precision mixing of medications is required. Traditional fully manual drug preparation methods are not only labor-intensive and inefficient, but also prone to errors due to human factors during dosage extraction and mixing, and may even lead to microbial contamination, posing medication safety risks to patients.
[0003] To overcome the drawbacks of manual operation, automated medication dispensing equipment has emerged. While some existing automated equipment can replace manual labor to a certain extent in performing actions such as extraction and drainage, improving the accuracy of individual operations, it still falls short in terms of the overall automation level of the workflow. For example, when processing multiple medications or dispensing medications for multiple patients, operators still need to frequently and manually change different medication bottles and place them in the designated working positions on the equipment. The entire process is repeatedly interrupted by manual intervention, failing to fundamentally solve the problem of low medication dispensing efficiency.
[0004] Furthermore, while some highly automated devices attempt to address the problem of continuous handling of multiple medication vials, their structures are often complex, and they do not adequately consider the securing method of the final preparation container (such as infusion bags or bottles). Existing clamping structures are typically simple, and during equipment operation, vibrations or other factors may cause the preparation container to shift, affecting the accurate injection of the needle, or even causing the container to detach. This not only interrupts the medication preparation process but also introduces risks of medication waste and contamination. Therefore, current technology has not yet provided a compact and reliable solution that efficiently integrates the automated transfer of multiple medication vials with the stable clamping of the final preparation container.
[0005] Therefore, this invention proposes a quantitative dispensing device for intravenous administration to address the shortcomings of existing technologies. Summary of the Invention
[0006] In view of the problems of low efficiency in automated transfer and positioning of multiple medicine bottles and insufficient clamping stability of the final preparation container in the existing intravenous preparation quantitative dispensing device, this utility model aims to provide an intravenous preparation quantitative dispensing device with an improved structure that can effectively solve the above problems.
[0007] This utility model provides a quantitative dispensing device for intravenous preparation, including: a dispensing machine, a rotating shaft, a turntable, and a dispensing base; as well as a fixing ring, an adjusting ring, a linkage plate, and a sliding shaft disposed on the turntable, and a clamping mechanism disposed on the dispensing machine, the clamping mechanism including a clamping plate, a rotating shaft, and a spring.
[0008] The rotating shaft is rotatably mounted on the dispensing machine, the turntable is fixed to the rotating shaft, and the dispensing seat is located below the turntable.
[0009] Furthermore, in the medicine bottle clamping structure, the fixing ring is located on the turntable, and the adjusting ring is located inside the fixing ring. The adjusting ring is connected to the sliding shaft via the linkage plate. In the container clamping mechanism, the clamping plate is rotatably installed via the rotating shaft, and the two ends of the spring are respectively connected to the clamping plate and the dispensing machine. Through this structural combination, the automated transfer and positioning of the medicine bottle and the stable clamping of the dispensing container are realized.
[0010] Preferably, a connecting plate is fixed to the edge of the turntable, and the fixing ring is fixed to the connecting plate.
[0011] Preferably, the axial movement of the sliding shaft drives the linkage plate, which in turn pushes the adjusting ring to clamp the medicine bottle.
[0012] Preferably, the clamping mechanism further includes a pull plate connected to the clamping plate, which is used to conveniently drive the clamping plate to rotate against the spring force.
[0013] Preferably, the clamping mechanism further includes an abutment block, which is disposed on the dispensing machine and located within the clamping space of the card plate, for assisting in abutting the dispensing container.
[0014] Preferably, the clamping mechanism further includes a limiting plate, which is fixedly disposed next to the rotating shaft to limit the rotation range of the clamping plate.
[0015] Preferably, the dispensing machine has a base at its bottom to enhance the overall stability of the device.
[0016] Preferably, the outer casing of the dispensing machine is provided with heat dissipation holes for heat dissipation during equipment operation.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Example:
[0030] Please refer to Figures 1 to 5 This utility model provides a quantitative dispensing device for intravenous preparation, which aims to solve the problems of low structural integration and cumbersome operation of existing intravenous dispensing devices in terms of automated transfer of medicine bottles and stable clamping of preparation containers.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the intravenous dispensing device includes a base 3 and a dispensing machine 1 fixedly connected to the base 3. The dispensing machine 1 serves as the main body of the entire device, and its outer shell has heat dissipation holes 2. A rotating shaft 4 is rotatably mounted on the dispensing machine 1, and a turntable 5 is fixed on the rotating shaft 4. The turntable 5 is used to carry and transport multiple medicine bottles. A dispensing seat 6 is also provided on the dispensing machine 1 below the turntable 5. The dispensing seat 6 is used to extract the medicine from the medicine bottles transported from the turntable 5 to its upper part.
[0032] To solve the above-mentioned technical problems, the core of the technical solution in this embodiment lies in the medicine bottle clamping structure integrated on the turntable 5 and the configuration container clamping mechanism set on the dispensing machine 1.
[0033] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 3 The following is a detailed description of the medicine bottle clamping structure: A connecting plate 7 is fixed to the edge of the turntable 5. A fixing ring 8 for accommodating the mouth of the medicine bottle is fixed on the connecting plate 7. An adjusting ring 9 is provided on the inner side of the fixing ring 8. The adjusting ring 9 is connected to the sliding shaft 10 through the linkage plate 11. Specifically, the axial movement of the sliding shaft 10 drives the linkage plate 11, and the linkage plate 11 in turn pushes the adjusting ring 9 to produce radial movement, thereby clamping the medicine bottle placed in the fixing ring 8. This linkage structure realizes the quick and reliable fixation of the medicine bottle.
[0034] Please refer to the following carefully. Figure 1 and Figure 4 The following is a detailed description of the container clamping mechanism: A clamping plate 12 is rotatably connected to the dispensing machine 1 via a rotating shaft 17. A spring 13 is also connected between the clamping plate 12 and the dispensing machine 1. The elastic force of the spring 13 causes the clamping plate 12 to tend to clamp the container. A pulling plate 14 is also connected to the clamping plate 12. By pulling the pulling plate 14, the clamping plate 12 can be rotated around the rotating shaft 17 to overcome the elastic force of the spring 13 and put in or take out the container. In addition, an abutment block 15 is provided in the clamping space of the clamping plate 12 on the dispensing machine 1 to assist in abutting the container. A limit plate 16 is fixedly provided next to the rotating shaft 17. The limit plate 16 is used to limit the rotation range of the clamping plate 12 to prevent it from deviating and falling off.
[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:
[0036] As one specific implementation method, please refer to Figure 2 To facilitate the installation and positioning of the fixing ring 8, a connecting plate 7 is fixedly connected to the edge of the turntable 5, and the fixing ring 8 is fixedly installed on the connecting plate 7.
[0037] Further, please refer to Figure 3 The specific implementation of the medicine bottle clamping method is as follows: the sliding shaft 10 drives the linkage plate 11 to move axially, and the linkage plate 11 then pushes the adjustment ring 9 to clamp the medicine bottle.
[0038] As a preferred embodiment, please refer to Figure 4 In order to facilitate the operator to open the clamping mechanism, a pull plate 14 is also connected to the clamping plate 12. The clamping plate 12 can be opened by applying a pulling force to the pull plate 14.
[0039] For further optimization of the clamping mechanism, please refer to... Figure 4 The dispensing machine 1 also has an abutment block 15 installed in the clamping space of the clamping plate 12. The abutment block 15 is used to assist in abutting the dispensing container from the other side, improving the stability of clamping. To ensure the reliable operation of the clamping mechanism, please refer to... Figure 4 A limit plate 16 is also fixedly installed next to the rotating shaft 17. The limit plate 16 is used to limit the rotational stroke of the clamping plate 12 to prevent it from deviating. To improve the overall stability of the device, please refer to... Figure 1 and Figure 5 The bottom of the dispensing machine 1 is fixedly connected to the base 3; considering that the equipment will generate heat during long-term operation, heat dissipation holes 2 are provided on the outer shell of the dispensing machine 1 to dissipate internal heat in a timely manner.
[0040] The working principle of this utility model's intravenous quantitative drug preparation device is as follows:
[0041] During medication preparation, the medicine bottle to be prepared is first installed in the fixing ring 8 fixed by the connecting plate 7 on the outer side of the turntable 5. The sliding shaft 10 drives the linkage plate 11, which in turn pushes the adjusting ring 9 to clamp the medicine bottle. Then, the rotating shaft 4 is started, causing the turntable 5 to rotate and transfer the clamped medicine bottle to the dispensing seat 6 below the dispensing machine 1. The automatic dispensing device on the dispensing seat 6 then picks up the liquid medicine. For the final preparation container, the pulling plate 14 is pulled, causing the clamping plate 12 to rotate and open around the rotating shaft 17, allowing the preparation container to be placed inside. When released, the rebound force of spring 13 will cause the clamping plate 12 to clamp the container, and the abutment block 15 will also abut against the container to assist in fixing it. The limiting plate 16 will limit the rotation of the clamping plate 12. During the operation of the equipment, the heat dissipation holes 2 on the outside of the dispensing machine 1 can dissipate the heat generated by the equipment in time, and the base 3 provides stable support for the entire device. Through the coordinated work of the automatic transfer and positioning structure of the turntable 5 and the independent spring clamping mechanism, this utility model effectively solves the problems of low structural integration and cumbersome operation in the prior art.
[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
