Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0025] Such as Figures 1 to 3 As shown, a self-adaptive negative pressure suction head, the main components involved are: a suction head assembly 1, a support 3, an elastic element 4, wherein the support 3 is composed of a suction head seat cover 31 and a suction head base 32 in the height direction Assembled structure, the floating positioning inner cavity 33 inside the support 3 is surrounded by the tip holder cover 31 and the tip base 32, and the tip assembly 1, the tip holder cover 31 and the tip base 32 are all made of aluminum alloy . The suction head assembly 1 has a central ventilation hole 1a. The suction head assembly 1 includes an air pressure inlet joint 12, a suction head body 11 and a suction head rubber 13 connected sequentially from top to bottom. The middle part of the suction head body 11 is provided with The protruding floating positioni...

Abstract

The invention discloses a self-adaptive negative pressure suction head, which comprises a suction head assembly with a central vent hole, wherein a floating positioning part protruding outwards in the radial direction of the suction head assembly is arranged in the middle of the suction head assembly, a support is arranged at the position corresponding to the floating positioning part in a sleeving mode, the support is provided with a floating positioning inner cavity, a positioning groove is formed in the side wall of the floating positioning inner cavity, the floating positioning portion is provided with a positioning protrusion matched with the positioning groove, the floating positioning portion is elastically supported in the floating positioning inner cavity through an elastic element, the positioning protrusion is embedded into the positioning groove under the action of the elastic element, and the suction head assembly and the support are combined into a whole. The self-adaptive negative pressure suction head has the beneficial effects that the lower end of the suction head assembly can be adaptively adjusted to be level with the upper end surface of the reaction cup through shaking of the floating positioning part, so that the suction head assembly can successfully grab the reaction cup.

Description

technical field [0001] The invention belongs to the field of medical detection equipment, and in particular relates to an adaptive negative pressure suction head. Background technique [0002] In immunoassay experiments, chemiluminescence immunoassay methods are usually used to detect and analyze body fluids, and chemiluminescence immunoassays are a means of detection using the specific reaction of antigens and antibodies. [0003] Using chemiluminescent immunoassay equipment to detect and analyze samples involves filling, mixing, incubation, washing, testing and cleaning. In order to meet the requirements of high automation of equipment, liquids such as samples or reagents need to be packed in reaction cups In the middle, and then grasped by the negative pressure suction head, so as to realize the operation of the cuvette between the various stages of detection. [0004] However, in the actual detection and analysis process, since the uniqueness of the cuvette’s posture ca...
