Embodiment 1

[0037] like Figure 1-9 As shown, the device for collecting biochemical samples includes a collection and filtration mechanism 1 and a separation and purification mechanism 2. The collection and filtration mechanism 1 includes a cavity-11, the height of which is adjustable, and an opening and a built-in electrified electrode-14 The original sample collection bottle 13 is used to accommodate the biochemical samples to be processed, and is detachably connected to the opening side of the cavity one 11; the rotating mechanism one 12 includes a connecting shaft one connecting the notch one 121 and the screw mechanism 123 at both ends respectively 122, used to drive the original sample collection bottle 13 to move up and down along the cavity one 11, the cavity one 11 is divided into two regions by the filter diaphragm 124 connected in the middle of the connecting shaft one 122; There is a buffer solution 26 that can be transferred to the first cavity 11 and an electrode two 25 that...

Embodiment 2

[0057] When the device and assembly for biochemical sample collection of the present invention are actually used, the driving mechanism 3 is first fixed, and the cover 111a and cover 2 111b installed on the upper and lower holes of the side wall of the cavity 11 for sealing and antifouling are installed on the Pull out the leak-proof cover three 21a and cover four 21b on the upper and lower holes on the side wall of cavity two 21, connect the corresponding holes with a drainage tube, and swing the bottle body 271 of the separated sample collection bottle 27 into the turntable 223. The collected and filtered mechanism 1 and the separation and purification mechanism 2 after docking are adsorbed and suspended on the corresponding positions on the driving mechanism 3 . The original sample collection bottle 13 is screwed into the opening side of the cavity one 11 to form a closed space after collecting the samples. When the rotating mechanism one 12 rotates, under the guidance of th...

Abstract

The invention discloses a device and an assembly for collecting biochemical samples, which belong to the technical field of biochemical equipment. The device comprises a collecting and filtering mechanism, a separating and purifying mechanism and a driving mechanism, wherein the collecting and filtering mechanism and the separating and purifying mechanism are removably mounted on the driving mechanism; a through drainage pipe is horizontally connected between the collecting and filtering mechanism and the separating and purifying mechanism; a shunting mechanism of the separating and purifyingmechanism comprises a shunting pipe adopting a Venturi tube principle and resistor loops connected in series with different resistance values; and the driving mechanism can be in butt joint with a first notch and a second notch to drive a first connecting shaft and a second connecting shaft to rotate correspondingly, and is communicated with a first electrode and a second electrode for electrophoretic separation. By adopting the device and the assembly, the phenomena of separation sample belt mixing, sample denaturation and easy capillary tube blockage caused by medium temperature rise due toheating during electrophoresis separation of a biochemical sample are avoided, the buffer solution is recycled to reduce pollution, the separation efficiency is high, the effect is good, the detectionaccuracy can be ensured by storing the samples in vacuum, and all required types of separated samples can be separated and collected at one time.

Description

technical field [0001] The invention belongs to the technical field of biochemical equipment, and in particular relates to devices and components for collecting biochemical samples. Background technique [0002] The collection of biochemical samples as a clinical activity to assist in the diagnosis and treatment of diseases is of great significance in clinical diagnostic applications. Clinical samples include blood, feces, urine, pleural and ascites, etc. The classification and counting of sample components, especially the rapid and accurate quantitative counting of some specific rare components, is very important for doctors to correctly diagnose the patient's condition and monitor the patient's recovery process. [0003] Patent US08062903B2 provides a method and apparatus for overcoming deleterious diffusion effects in a sample liquid stream by forming segmented liquids from the sample liquid stream in an immiscible liquid stream. Liquid is formed at the intersection of c...
