Description

Technical Field

[0001] The utility model relates to the technical field of medicine packaging, in particular to a self-sealing glue joint of a glass medicine irrigator. Background Art

[0002] Glass volumizer, also known as glass infuser, is used to hold the required liquid medicine. It is a pharmaceutical preparation equipment that mainly uses glass as the filling material, which can effectively ensure the quality and safety of the medicine. The glass volumizer is also equipped with a sealing glue joint to ensure the sealing and safety of the medicine during storage and transportation.

[0003] Sealing glue joints are usually made of high-quality soft materials such as rubber or silicone. They are not only elastic but also durable. They are designed with transparent or translucent materials to ensure that users can clearly observe the flow of drugs and thus conduct precise control. However, the current sealing glue joints are mainly connected to the liquid outlet of the glass irrigator by plugging. Although this connection method is convenient for quick disassembly, it has obvious shortcomings: the connection is not stable enough and is easy to fall off. In view of this, we propose a self-sealing glue joint for the glass irrigator. Utility Model Content

[0025] This embodiment provides a technical solution:

[0026] See also Figure 1-Figure 4 , a self-sealing adhesive joint for a glass irrigator, comprising a glass irrigator 1. The glass irrigator 1 comprises an irrigating cartridge 10 with an opening at the rear end, and two symmetrical clamps 102 are installed on the front end surface of the irrigating cartridge 10; a liquid outlet head 11 is coaxially fixed at the center of the front end of the irrigating cartridge 10, and two limit rings 111 are coaxially fixed on the outer wall of the liquid outlet head 11; an ear plate 101 is installed at the rear end of the outer wall of the irrigating cartridge 10, and a piston 12 is slidably installed in the opening of the irrigating cartridge 10, and a push block 14 is provided on the rear side of the piston 12, and a push rod 13 is coaxially fixed between the push block 14 and the piston 12; a self-sealing adhesive joint is provided on the outside of the liquid outlet head 11; the self-sealing adhesive joint comprises a connecting plate 17, a connecting ring 16 and an adhesive head 15 which are arranged in sequence from back to front, the connecting ring 16 and the adhesive head 15 are tightly bonded, and the liquid outlet head 11 passes through the connecting plate 17, a connecting ring 16 and an adhesive head 15, and ... The connecting plate 17 and the connecting ring 16 are inserted into the rubber head 15; the connecting plate 17 is coaxially fixed with the connecting ring 16, and the outer wall of the connecting plate 17 is provided with a card slot 171 that is engaged with the card head 102; the rear end of the rubber head 15 is provided with a liquid inlet cavity 151 that is plugged into the liquid outlet head 11, and the inner wall of the liquid inlet cavity 151 is provided with two limiting grooves 155, and the limiting ring 111 is inserted into the limiting groove 155, and the front end of the rubber head 15 is provided with an interface 152, and the interior of the rubber head 15 is provided with a plurality of expandable flow channels 154 that are used for the circulation of liquid medicine and can be deformed, and adjacent expandable flow channels 154 are connected through the connecting cavity, and the outer wall of the rubber head 15 is provided with a plurality of inner grooves 153, and the inner grooves 153 are located outside the expandable flow channels 154.

[0027] In this embodiment, the rubber head 15 is made of rubber material, and the outer wall of the liquid inlet cavity 151 is closely fitted with the outer wall of the liquid outlet head 11. The rubber material has certain elasticity and drug resistance. The use of this material can tightly seal the expandable flow channel 154 when there is no external force to prevent drug leakage. At the same time, it is ensured that the drug will not leak from the connection between the liquid outlet head 11 and the liquid inlet cavity 151.

[0028] In this embodiment, the connecting plate 17 and the connecting ring 16 are integrally formed, and both the connecting plate 17 and the connecting ring 16 are made of plastic. The integrally formed connecting plate 17 and the connecting ring 16 have better structural strength, which ensures the service life of the connecting plate 17 and the connecting ring 16.

[0029] In this embodiment, the clamp head 102 is a plastic product, and the clamp head 102 is tightly bonded to the drug filling cartridge 10. The plastic clamp head 102 has the advantage of being easy to process, and is also conducive to the clamping and matching of the clamp head 102 and the clamping slot 171.

[0030] In this embodiment, the cross-sectional shape of the limiting ring 111 and the cross-sectional shape of the limiting groove 155 are both annular, and the size of the limiting ring 111 is adapted to the size. This design ensures the close fit between the limiting ring 111 and the limiting groove 155, and improves the connection reliability between the rubber head 15 and the liquid outlet head 11.

[0031] In this embodiment, the drug filling cartridge 10, the liquid discharge head 11 and the limiting ring 111 are an integrally formed structure, and the drug filling cartridge 10, the liquid discharge head 11 and the limiting ring 111 are all made of glass. The integrally formed drug filling cartridge 10, the liquid discharge head 11 and the limiting ring 111 have better structural strength, ensure the connection reliability of the drug filling cartridge 10, the liquid discharge head 11 and the limiting ring 111, and ensure the service life of the drug filling cartridge 10, the liquid discharge head 11 and the limiting ring 111.

[0032] It should be added that the preferred number of expandable flow channels 154 in this embodiment is 2. This design enables the rubber head 15 to have a double sealing effect, thereby improving the sealing performance of the rubber head 15.

[0033] During specific assembly, the user first passes the liquid outlet head 11 through the connecting plate 17 and the connecting ring 16, and inserts it into the liquid inlet cavity 151. Then, the user aligns the clamping groove 171 with the clamping head 102 and presses the connecting plate 17 on one side of the clamping head 102. The clamping head 102 is plastically deformed and clamped into the clamping groove 171. Then, the user continues to push the rubber head 15, and the limiting groove 155 is clamped on the outside of the limiting ring 111. The self-sealing rubber joint is assembled.

[0034] When the push block 14 is pushed, the push rod 13 pushes the piston 12 to move. At this time, the medicine in the medicine cartridge 10 enters the liquid inlet chamber 151 through the liquid outlet head 11. Under the action of pressure, the expandable flow channel 154 is deformed and expanded. At this time, the medicine passes through the expandable flow channel 154, and finally the medicine flows out to other containers through the interface 152.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
