Description
Technical field
The utility model relates to a kind of multiplexing online dislysate sampling cock, specifically for the online dislysate that extracts in real time on haemodialysis control unit.
Background technique
At present, haemodialysis control unit, in treatment clinical course, needs regularly in the situation that the online dislysate that extracts in real time of equipment operation carries out biochemistry detection.On existing dislysate pipeline, sampling cock is not set, during sampling, can only disconnects pipeline and be sampled.So not only troublesome poeration, and dislysate is easily contaminated, makes sampling operation very inconvenient.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of multiplexing online dislysate sampling cock that prevents from polluting dislysate.
The technical solution of the utility model is as follows: a kind of multiplexing online dislysate sampling cock, comprise block body (3), have the first via hole (5) that left and right connects in the middle and lower part of described body (3), have the step hole communicated with the first via hole (5) on the top of body (3), the small aperture section of this step hole communicates with the first via hole (5), be coated with sealing gasket (4) on the step surface of the small aperture of described step hole, be pressed with lid (2) on described sealing gasket (4), the step hole enlarged diameter section hole wall screw-thread fit of this lid (2) and body (3), have second via hole (1) of up/down perforation in lid (2), the center line of this second via hole (1) overlaps with the center line of step hole.
Adopt said structure, the first via hole left and right of body middle and lower part connects, up big and down small step hole lower end, body top communicates with the first via hole, be pressed with sealing gasket by lid on the step surface of the small aperture of step hole, the sealing pad adopts medical grade rubber butyl rubber to be made, and in lid, have with the first via hole over against the second via hole; In using process, as long as body is connected on the dislysate pipeline, the two ends, left and right of the first via hole are connected with the dislysate pipeline, when sampling, sampling probe is inserted from the second via hole, and the puncture through seal pad, can extract quickly and easily dislysate and be detected, after extracting sampling probe, the sealing gasket automatic-sealed, be hedged off from the outer world the dislysate in the first via hole, effectively prevented that dislysate is contaminated, and sealing gasket can be pierced repeatedly, use very convenient.
The orifice diameter of described step hole lower end is 2.5-3.5mm, and when the orifice diameter of step hole lower end is less than 2.5mm, the area that can repeatedly pierce through for sampling probe is too little, and the replacement cycle of sealing gasket is shorter, uses inconvenient; When the orifice diameter of step hole lower end is greater than 3.5mm, the aperture of step hole lower end is too large, easily affects the pressure in the dislysate pipeline, brings adverse effect to the circulation of dislysate.
The step column that described lid (2) is big up and small down, on the enlarged diameter section of this lid (2), cut four facing each other flat aspect (2a), described the second via hole (1) consists of two sections, wherein the big up and small down bell mouth shape of the epimere of the second via hole, be arranged in the enlarged diameter section on lid (2) top, rounded poroid, the reduced diameter section that is positioned at lid (2) bottom of the hypomere of the second via hole.Such lid not only installing/dismounting is convenient, and the enlarged diameter section on top blocks the step hole of body fully, uses health, safety more; The setting of flat aspect makes the people more laborsaving when turning lid, and the epimere of the second via hole is the insertion that bell mouth shape can facilitate sampling probe.
It is block that described body (3) is abnormity, and the lower end surface of body (3) is protruding cambered surface downwards, circumferentially extend in the upper end of body (3), form circular baffle plate (3a), described body (3) stretches out at the two ends that have the first via hole (5), form the joint (3b) of circular tube shaped, the endoporus of described joint (3b) and the first via hole (5) connect, and described joint (3b) reduces gradually away from an end external diameter of body (3).Such body, when processing step hole, clamps convenient; The setting of circular baffle plate, make the profile of body more attractive in appearance; Joint is set, when the sampling cock body is connected with the dislysate pipeline, only silicone tube need to be enclosed within on joint, can connect quickly and easily.
The thickness of described sealing gasket (4) is 1.9-2.1mm.When the thickness of sealing gasket is less than 1.9mm, sealing gasket is too thin, the sealing gasket after not only piercing through self-closing and after sealing reduce, and easily affect the pressure in the dislysate pipeline; When the thickness of sealing gasket is greater than 2.1mm, not only there is no need, and the waste material.
Beneficial effect: the first via hole that the utility model connects by left and right is set in the body middle and lower part, body top arranges lower end and the step hole communicated with the first via hole, be fixed with sealing gasket by the interior lid of opening the second via hole on the step surface of step hole, effectively prevented that dislysate when sampling is contaminated, have be skillfully constructed, simple in structure, produce easily and the characteristics such as cost of production is low.
