Abstract
Description
Technical Field
[0001] This utility model relates to the field of cap opening technology, and in particular to a cap opening mechanism and a radiopharmaceutical dispensing device including the same. Background Technology
[0002] Radiopharmaceutical concentrate vials are typically packaged and distributed via distribution containers. In clinical use, the container lid needs to be opened to extract and dispense the concentrate for patient consumption. Currently, this process is mostly done manually, which is complex and poses a radiation hazard to medical personnel.
[0003] Based on this, this application creates a new cap-opening mechanism and a radiopharmaceutical dispensing device including it, enabling mechanized cap-opening action, providing favorable support for subsequent radiopharmaceutical dispensing steps, and truly reducing the harm of radiopharmaceuticals to medical personnel. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a cap-opening mechanism that enables mechanized cap-opening action, providing favorable support for subsequent radiopharmaceutical dispensing steps, truly reducing the harm of radiopharmaceuticals to medical personnel, and thus overcoming the shortcomings of existing radiopharmaceutical dispensing equipment.
[0005] To solve the above-mentioned technical problems, this utility model provides a cover opening mechanism, including a sliding shaft, a sliding base plate that slides up and down along the sliding shaft, an operating handle connected to the edge of the sliding base plate, and an opening and closing unit disposed on the sliding base plate;
[0006] The opening and closing unit includes an opening and closing lever, an opening and closing slider, opening and closing connecting rods, and opening and closing hooks. The opening and closing lever is located below the operating handle and has two pins in its middle. The first pin is rotatably connected to the sliding base plate, and the second pin is disposed in the central elongated hole of the opening and closing slider. The upper part of the opening and closing slider is connected to the upper part of the sliding base plate by a tension spring. An opening and closing connecting rod is connected to each of the two lower sides of the opening and closing slider. An opening and closing hook is connected to the lower end of each opening and closing connecting rod. The lower end of the opening and closing hook has a barb, and its upper end has two... There are two connection points: the outer connection point is hinged to the lower end of the opening and closing linkage, and the inner connection point is hinged to the sliding base plate. The two opening and closing hooks are arranged opposite each other. Under the elastic force of the tension spring, the opening and closing slider pushes the barbs at the lower ends of the two opening and closing hooks to tighten, so as to grasp the can lid to be opened. When the operating handle is lifted upward, the can lid is lifted and clamped. When the opening and closing control lever moves the opening and closing slider upward under the action of external force, the two opening and closing linkages drive the barbs at the lower ends of the two opening and closing hooks to unfold, thereby releasing the can lid.
[0007] In a further improvement, the opening and closing unit also includes a locking unit, which includes a locking plate fixed to the upper part of the sliding shaft and a locking block fixed to the inner end of the opening and closing control lever. A locking space is formed between the bottom of the locking plate and the sliding shaft. When the opening and closing control lever is not subjected to external force, the locking block can enter the locking space along with the sliding base plate to lock the opening and closing control lever.
[0008] In a further improvement, the sliding substrate is slidably mounted on the sliding shaft via a linear bearing.
[0009] A further improvement includes an outer casing, on the side wall of which is provided a vertical groove for the operating handle to extend, and the upper end of the vertical groove is provided with a locking element for locking the operating handle.
[0010] In a further improvement, the outer casing is provided with an opening limiting unit. The opening limiting unit includes an opening limiting rod fixed to the bottom of the sliding base plate and a limiting hole provided at the bottom of the outer casing. When the opening limiting rod moves downward with the sliding base plate, it can be inserted into the limiting hole to ensure that the opening mechanism can achieve the opening and positioning of the can lid.
[0011] In a further improvement, the outer end of the operating handle is provided with a telescopic handle sleeve. The telescopic handle sleeve retracts in its natural state and cooperates with the locking member to fix the operating handle. When the telescopic handle sleeve is pulled out under the action of external force, it can disengage from the locking member and drive the operating handle to slide up and down along the vertical slide groove.
[0012] As another improvement of this utility model, this utility model also provides a radiopharmaceutical dispensing device, which includes the above-mentioned opening mechanism, the opening mechanism being used to open the lid of the original liquid bottle distribution tank in the radiopharmaceutical dispensing device.
[0013] With this design, the present invention has at least the following advantages:
[0014] 1. The lid opening mechanism of this utility model is designed with an opening and closing unit. It uses spring tension to enable two opening and closing hooks to grip the lid, and the operating handle drives the sliding base plate to move up and down to lift the lid. Furthermore, the opening and closing control lever enables the opening and closing unit to release the lid. It is simple, convenient, scientific and labor-saving.
[0015] 2. Furthermore, the locking unit allows for easy locking of the can lid after it is lifted, preventing it from falling freely and interfering with subsequent steps, thus enhancing safety and reliability. The locking mechanism also ensures the operating handle can be securely held in place, providing operators with safer and more convenient operating conditions.
[0016] 3. Furthermore, the opening limit unit ensures the positioning of the can lid opening position and locks the opening position.
[0017] 4. The radiopharmaceutical dispensing equipment of this utility model, by setting the opening mechanism, can be used to open the lid of the original liquid bottle delivery tank in the radiopharmaceutical dispensing equipment, so that the radiopharmaceutical can be directly used in the drug dispensing step while it is inside the shell, which greatly reduces radiation hazards.

[0023] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0024] See attached document Figure 1 As shown, the opening mechanism of this embodiment includes a sliding shaft 1, a sliding base plate 2 that slides up and down along the sliding shaft 1, an operating handle 3 connected to the edge of the sliding base plate 2, and an opening and closing unit disposed on the sliding base plate 2. The sliding shaft 1 is vertically fixed to the outer casing. The sliding base plate 2 is slidably disposed on the sliding shaft 1 via a linear bearing 21.
[0025] The opening and closing unit includes an opening and closing lever 5, an opening and closing slider 6, an opening and closing connecting rod 7, and an opening and closing hook 8. The opening and closing lever 5 is located below the operating handle 3, and has two pins in its middle. The first pin 51 is rotatably connected to the sliding base plate 2, and the second pin 52 is disposed in the central elongated hole 61 of the opening and closing slider 6. The upper part of the opening and closing slider 6 is connected to the upper part of the sliding base plate 2 by a tension spring 9. An opening and closing connecting rod 7 is connected to each of the two lower sides of the opening and closing slider 6, and an opening and closing hook 8 is connected to the lower end of each opening and closing connecting rod 7. The lower end of the opening and closing hook 8 is provided with a barb 81. The upper end of the opening and closing hook 8 is provided with two connection points. The outer connection point 82 is hinged to the lower end of the opening and closing connecting rod 7, and the inner connection point 83 is hinged to the sliding base plate 2. The two opening and closing hooks 8 are arranged opposite each other. The opening / closing slider 6, under the elastic force of the tension spring 9, pushes the barbs 81 at the lower ends of the two opening / closing hooks 8 to tighten, thereby gripping the can lid 10 to be opened. When the operating handle 3 is lifted upwards, the can lid 10 is lifted and clamped, as shown in the attached figure. Figure 2 As shown in the attached diagram. When the opening / closing lever 5 moves the opening / closing slider 6 upward under external force, the two opening / closing connecting rods 7 cause the lower barbs of the two opening / closing hooks 8 to unfold, thereby releasing the can lid 10, as shown in the attached diagram. Figure 1 As shown.
[0026] The opening and closing unit also includes a locking unit, which includes a locking plate 11 fixed to the upper part of the sliding shaft 1 and a locking block 53 fixed to the inner end of the opening and closing lever 5. A locking space 12 is formed between the bottom of the locking plate 11 and the sliding shaft 1. When the opening and closing lever 5 is not subjected to external force, the locking block 53 can enter the locking space 12 along with the sliding base plate 2, that is, the locking plate 11 and the locking block 53 are tightly fitted, preventing the locking block 53 from rotating, thereby preventing the opening and closing lever 5 from rotating, thus forming a lock on the opening and closing lever 5, as shown in the attached figure. Figure 2 As shown, this is to prevent the lid 10 from falling off.
[0027] See attached document Figure 3 and 4 As shown, the radiopharmaceutical dispensing equipment in this embodiment includes the above-mentioned opening mechanism, which is used to open the lid 10 of the original liquid bottle delivery tank 20 in the radiopharmaceutical dispensing equipment.
[0028] Specifically, the opening mechanism is located inside the outer shell of the radiopharmaceutical dispensing equipment. The side wall of the outer shell is provided with a vertical groove for the operating handle 3 to extend out, and the upper end of the vertical groove is provided with a locking member 4 for locking the operating handle 3, so as to ensure that the operating handle 3 can be locked in the upper part of the vertical groove.
[0029] Furthermore, the outer end of the operating handle 3 is provided with a telescopic handle sleeve 31. In its natural state, the telescopic handle sleeve 31 retracts and cooperates with the locking member 4 to secure the operating handle 3. When the telescopic handle sleeve 31 is pulled out under external force, it disengages from the locking member 4, causing the operating handle 3 to slide up and down along the vertical groove. The locking member 4 can be any existing locking structure. The telescopic handle sleeve 31 can be an existing elastic telescopic structure, which simply needs to remain retracted in its natural state.
[0030] To ensure accurate positioning during cap opening, the radiopharmaceutical dispensing equipment in this embodiment also includes a cap opening limiting unit inside its outer casing. This unit comprises a cap opening limiting rod 22 fixed to the bottom of the sliding base plate 2 and a limiting hole 23 located at the bottom of the outer casing. When the cap opening limiting rod 22 moves downwards with the sliding base plate 2, it inserts into the limiting hole 23, ensuring alignment between the cap opening mechanism and the canister cap 10. Alternatively, the limiting hole 23 can be located on the movable base of the raw material bottle delivery canister 20; in this way, the cooperation between the cap opening limiting rod 22 and the limiting hole 23 further ensures the locking of the raw material bottle delivery canister 20.
[0031] This invention's lid-opening mechanism utilizes spring tension to grip the lid using two opening and closing hooks. The lid is lifted by moving a sliding base plate up and down via an operating handle. Furthermore, the opening and closing lever allows for the release of the lid from the opening and closing unit. This design is simple, convenient, scientific, and labor-saving. When used in radiopharmaceutical dispensing equipment, this mechanism easily opens the lids of the original solution delivery containers, facilitating the extraction of the original solution during subsequent dispensing of radiopharmaceuticals. This allows radiopharmaceuticals to be directly used in the dispensing process from within the outer casing, eliminating the need for manual opening and significantly reducing radiation hazards.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
