Abstract
Description
Technical field:
[0001] The present invention provides a puncture head, which is a component of a medical intelligent dispensing machine and belongs to the field of medical devices, and is particularly suitable for use in a centralized intravenous drug dispensing center in a hospital. Background technology:
[0002] Under the national advocacy, all general hospitals are actively establishing "centralized intravenous drug dispensing centers". All the infusion drugs of the hospital are concentrated in the "dispensing center" for centralized dispensing. The characteristics of centralized dispensing are: many drugs, large amounts of liquid to be dispensed, concentrated time, heavy workload, and the dispensing personnel are under pressure and highly concentrated. It is inevitable that mistakes will be made in a hurry, but the dispensing of drugs requires zero errors. Therefore, the dispensing method needs to be innovated, and an automated, efficient and pollution-free dispensing method has emerged. Summary of the invention:
[0003] 1. The present invention is a component of an intelligent mechanical device, which completes the automatic puncture of a vial during the process of dissolving a vial of powdered medicine and injecting a solvent. Due to the wide variety of vials and the need for strict disinfection of the equipment after use, the puncture head provided by the present invention is composed of a bottle height probe, a clamp, a slide, a bearing, and a power assembly. The power assembly drives the slide to move, and the clamp is composed of a clamp 1, a clamp 2, and a clamp 3. The characteristics are: the clamp 2 is mounted on the slide and moves with the slide, and the clamp 2 is provided with a clamp 1 relative to the clamp 1. The adaptable limit platform, the clamper 1 is buckled on the limit platform of the clamper 2, and is positioned by the positioning magnets installed on the clamper 1 and the clamper 2. When replacing disposable consumables, it can be longitudinally dislocated and removed; the limit platform of the clamper 2 is provided with a positioning groove adapted to the clamper 3, and the clamper 3 is installed in the positioning groove provided for it on the clamper 2, and is positioned by the positioning magnets installed on the clamper 2 and the clamper 3. When replacing disposable consumables, it can be horizontally dislocated and removed. Installing the clamper 1 limits the lateral movement and dislocation of the clamper 3; the bottle height probe is installed in the slide groove of the bearing.
[0004] It can slide longitudinally and is positioned and reset by magnets.
[0005] With this structural design, the only parts that come into contact with the disposable consumable material puncture needle are the clamp 1 and the clamp 3. The part clamp 1 can be easily removed by longitudinal dislocation to install or remove the puncture needle. After the clamp 1 is removed, there is no limiting effect of the clamp 1, and the clamp 3 can be removed by left and right dislocation. The two parts can be immersed and disinfected, and the other parts that are not in contact with the puncture needle can be wiped and disinfected on the surface; the bottle height probe is installed in the slide groove of the support component and can slide longitudinally. It is positioned and reset by a magnet. During operation, as the puncture head moves, the bottle height probe presses onto the syringe bottle and slides in the slide groove of the support component. The positioning magnet triggers the bottle height sensor to realize height detection and positioning. At the same time, the reset magnet is misaligned. When the puncture head is reset and the bottle height probe leaves the syringe bottle, the reset magnet resets it like a spring. The bottle height probe is in direct contact with the syringe bottle and can be removed for immersion, cleaning and disinfection.
[0006] The present invention is achieved through the following solutions: Description of the drawings:

[0011] Specific implementation: The following is a typical embodiment described in conjunction with the accompanying drawings. The specific structural forms of the dispensing needle are diverse and are not limited to the forms of the embodiments given in the specification. Other forms are within the scope of protection of the patent claims.
[0012] Example 1 puncture head:
[0013] The clamp consists of three parts. Part 4 clamp 2 is provided with a limit platform for part 3 clamp 1, and the limit platform is provided with a positioning slot for part 7 clamp 3. Part 7 clamp 3 is installed in the positioning slot provided for it on part 4 clamp 2 and can move horizontally. It is positioned by part 8 positioning magnets installed on part 4 clamp 2 and part 7 clamp 3. Part 3 clamp 1 is placed on the limit platform on part 4 clamp 2 and can move vertically. It is positioned by part 8 positioning magnets installed on part 3 clamp 1 and part 4 clamp 2. Part 3 clamp 1 limits the lateral movement of part 7 clamp 3. Disposable consumables need to be installed. During puncture, Part 3's Clamp 1 is displaced longitudinally for easy removal. A disposable puncture needle can then be installed and replaced in Part 3's Clamp 1. Part 3's Clamp 1, under the action of Part 8's positioning magnet, secures the puncture needle to the clamp. Following this procedure, the puncture needle can also be easily removed. With this structural design, the only parts that come into direct contact with the puncture needle are Part 3's Clamp 1 and Part 7's Clamp 1. First, displace Part 3's Clamp 1 longitudinally to remove it, then displace Part 7's Clamp 3 laterally to remove it. These two parts can be soaked, cleaned, and disinfected. Other parts not in direct contact with the puncture needle can be surface-wiped and disinfected. Part 4's Clamp 2 is mounted on Part 5's slide. Driven by power assembly 10, Part 5's slide moves longitudinally, driving the clamp to puncture the medicine bottle. Part 1's bottle-height probe, mounted in the slot of Part 6's support, can slide longitudinally. It is positioned by Part 11's bottle-height probe positioning magnet and reset by Part 12's bottle-height probe reset magnet. During operation, as the puncture head moves, the bottle-height probe of part 1 presses onto the vial and slides in the slide of part 6. The positioning magnet of the bottle-height probe of part 11 triggers the bottle-height sensor of part 9 to achieve height detection and positioning. At the same time, the reset magnet of the bottle-height probe of part 12 is misaligned. When the puncture head is reset and the bottle-height probe of part 1 leaves the vial, the reset magnet of the bottle-height probe of part 12 acts like a spring to reset it. The bottle-height probe of part 1 is in direct contact with the vial and can be directly removed for immersion, cleaning, and disinfection. The puncture head can automatically position the height of vials of any specification and puncture with the shortest distance of the puncture needle. The parts in direct contact with the vial and the puncture needle can be easily removed for immersion, cleaning, and disinfection, which has a positive effect on improving efficiency and safety assurance of automatic equipment.
