Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and more specifically, relates to an ampoule cutting device. Background Technology

[0002] Ampoules are small glass containers used to hold liquid medicines. Their structure includes a body and a head, as well as a neck that is recessed between the body and the head. The capacity is generally 1 to 25 ml, and they are generally used for injectable liquid medicines.

[0003] Currently, when preparing medication solutions for ampoules, the common practice is to first score the neck of the ampoule with a scalpel, then sterilize it, and then break off the upper part of the ampoule by hand or other tools. Finally, the medication in the ampoule is drawn into a mother solution bag using a syringe. This method requires manual breaking of the ampoule, and if the force applied when scoring the ampoule with a scalpel is not properly controlled, it can easily cause injury to medical personnel. Therefore, in view of this, this paper studies and improves the existing structure and its shortcomings, providing an ampoule cutting device to achieve a more practical purpose.

[0028] As attached Figure 1 To be continued Figure 8 As shown:

[0029] This invention provides an ampoule cutting device, comprising a main housing 1, with an installation port and an operation port on one side of the front of the main housing 1. A panel 2 is sealed to the outside of the installation port. A fixing sleeve 3 for fitting the neck of the ampoule is installed on the top of the main housing 1 near the operation port. A partition 4 is vertically installed inside the main housing 1. A mounting plate 5 and a mounting plate 6 are respectively connected to the left and right sides of the partition 4. A transmission arm 7 is slidably installed on one side of the mounting plate 5. The right end of the transmission arm 7 passes through the partition 4, and a push block 10 is installed on the right side of the partition 4. A trigger 8 for locking the transmission arm 7 is rotatably installed on one side of the mounting plate 5. The left end of the transmission arm 7 is fitted with a second tension spring 11 and a third tension spring 12 via fasteners. The other end of the second tension spring 11 is fixedly connected to the mounting plate 5 via fasteners. The other end of the third tension spring 12 is fixedly connected to a steel rope 14, and a drive column 15 for driving the trigger 8 to unlock is fixedly installed on the outside of the steel rope 14. The right end of the steel rope 14 passes through the partition 4 and is connected to a sliding plate 16. The sliding plate 16 is slidably installed on the bottom side of the mounting plate 6, and the fixing sleeve 3 is fixedly installed on one side of the sliding plate 16. A U-shaped through groove is provided on one side of the mounting plate 6, and a bottle cutting assembly 9 is installed on the top of the mounting plate 6 near the left side of the U-shaped through groove.

[0030] The panel 2 is installed at an angle on one side of the front of the main housing 1, and the first mounting plate 5 is arranged parallel to the panel 2, while the second mounting plate 6 is arranged perpendicular to the panel 2, so that the second mounting plate 6 is in an inclined state after installation, which is conducive to quickly removing glass shards during use.

[0031] Panel 2 is a transparent acrylic plate, which allows the internal components to be observed during bottle cutting so that a timely response can be made in case of malfunction. The transparent acrylic plate has an clearance groove on the top side near the mounting location of the fixing sleeve 3 so that the fixing sleeve 3 and the ampoule can enter smoothly for ampoule cutting.

[0032] The trigger 8 includes an L-shaped plate 801, with a locking plate 802 and a drive plate 803 respectively at both ends. The bottom side of the transmission arm 7 is provided with a locking groove 701 that can engage with the locking plate 802. One side of the drive plate 803 is provided with a U-shaped slot for the steel rope 14 to pass through, and the opening width of the U-shaped slot is smaller than the diameter of the drive column 15, so that when the steel rope 14 moves, the drive column 15 can drive the drive plate 803 to move, thereby driving the trigger 8 to rotate and unlock. The L-shaped plate 801 is rotatably connected to the mounting plate 5 by a shaft pin.

[0033] The bottle cutting assembly 9 includes a fixed cover 901 that is fastened to the top of the mounting plate 6 by fasteners. The fixed cover 901 has an opening on one side of its bottom, and a cutter arm 903 is rotatably mounted inside the opening via a pivot pin. A cutter 904 is fixedly mounted on the right end of the cutter arm 903, and one end of the cutter 904 is located on the top side of the U-shaped through groove. A tension spring 902 is fastened to the top of the right end of the cutter arm 903, and the other end of the tension spring 902 is fastened to the top side of the fixed cover 901. The tension spring 902 ensures that the cutter 904 can fit tightly against the ampoule neck when the ampoule neck passes through, thus achieving a cut, and can drive the cutter arm 903 and the cutter 904 back to their original positions when the ampoule neck has completely passed through.

[0034] Among them, slide rail 17 and slide rail 28 are fixedly installed on one side of mounting plate 15 and mounting plate 26 respectively. Slide seats are slidably installed on the surface of slide rail 17 and slide rail 28. The two sets of slide seats are fixedly connected to the transmission arm 7 and the sliding plate 16 respectively. By installing and using slide rail 17 and slide rail 2, the accuracy of movement of transmission arm 7 and sliding plate 16 can be effectively improved, so as to facilitate rapid bottle cutting operation.

[0035] Among them, an installation shaft is fixedly installed on one side of the bottom of the installation plate 2 6, and a fixed pulley 13 is rotatably installed on one end of the installation shaft. The right end of the steel rope 14 passes around the fixed pulley 13 and is fixedly connected to the sliding plate 16. The setting of the fixed pulley 13 can effectively improve the smoothness of the steel rope 14 when moving.

[0036] The main housing 1 has a collection chamber near the operation port, and a waste box 19 is slidably installed inside the collection chamber. The top of the waste box 19 is open to facilitate the quick collection of glass shards knocked out by the pusher 10, which is conducive to subsequent centralized processing. Multiple sets of silicone strips 20 are fixedly bonded to the bottom of the main housing 1 to ensure high stability when the whole is placed.

[0037] The working principle of this embodiment is as follows: In use, first place the device on a horizontal platform. Then, insert the ampoule through the bottom end of the fixing sleeve 3, ensuring the top end protrudes from the top of the fixing sleeve 3, thus exposing the neck of the ampoule. Next, push the fixing sleeve 3 with your finger, causing it to drive the sliding plate 16 to move into the U-shaped groove. During this movement, the neck of the ampoule will contact the cutter 904, cutting the neck of the ampoule. Simultaneously, the steel cable 14 will be pulled by the sliding plate 16, causing the drive column 15 to move, and simultaneously pulling... When spring 12 is extended, and the ampoule moves to the bottom of the U-shaped groove, the drive column 15 contacts the drive plate 803 of the trigger 8, driving the trigger 8 to rotate. At this time, the latch plate 802 of the trigger 8 separates from the latch 701, and the transmission arm 7 moves to the right under the action of spring 12. Through the push block 10 at its right end, the bottle head of the ampoule is broken off, realizing the opening operation. After that, the opened ampoule can be taken out from the bottom of the fixed sleeve 3. After taking it out, the transmission arm 7 and the sliding plate 16 can return to their original positions under the action of spring 11 for the next operation.

[0038] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
