Embodiment Construction

[0016] FIG. 1 shows a double cartridge 1 with a coupling ring 2 for connecting a delivery part 3 on which a calibration device 4 is fitted. The coupling ring and cartridge comprise known bayonet fastening means. Other fastening means, such as snap rings, are also possible. Calibration devices for adjusting the relative heights of the components to ensure an exact mixing ratio between the components from the beginning of the dispensing operation or mixing operation respectively, and for completely venting the air in the double cartridge to avoid entrapment in it There is air trapped. In the field of medical technology, both states are extremely important.

[0017] When applied to endoscopes, such as corresponding laparoscopes, the diameter of the delivery part and the mixer cannot exceed a certain smaller value and cannot have stepped parts. However, for economical reasons, commercially available cartridges are used which can also be used in other applications and whose over...

Abstract

Disclosed is a two component dispensing system comprising a dispenser cartridge or dispensing apparatus and a mixer. A transfer part (3) which can be connected to both the cartridge (1) or apparatus and the mixer (5) is disposed therebetween. In a preferred embodiment, an adapter (10, 21) is placed on both sides of the transfer part. Said transfer part (3) is provided with a cylindrical bar (38), within the circumference of which two longitudinal grooves (39, 40) are arranged. The bar (38) is enclosed so tightly by a jacket tube (28) that two ducts (17, 18) are formed which allow no material to travel from one duct to the other. Such an arrangement allows for simple production of the transfer part and reliable working conditions, which are important above all in laparoscopy because the distance between the dispenser cartridge and the point of intervention in the abdominal cavity is quite large.

Description

technical field [0001] The present invention relates to a dosing set, in particular to a dosing set for two or three components. Background technique [0002] In most dosing sets, the mixer is fastened to the cartridge and the set is used in this form. An accessory is often attached to the mixer to influence the shape of the mixed components and to allow the targeted application of the drug to the desired location in special cases. However, there are many situations, more specifically in medicine, where such a simple combination of dispensing cartridge, mixer and accessory equipment is not sufficient. [0003] In medicine, some joints are now achieved by sealing rather than suturing, for which a two-component sealant is used. Thus, the application of the dosing set, for example in procedures involving the use of an endoscope, requires a long delivery section between the cartridge and the mixer, especially when laparoscopy. In laparoscopy, longer tubes are introduced into ...
