Abstract
The utility model relates to a plasma separating cup with a center pipe of an umbrella-shaped structure. The plasma separating cup with the center pipe of the umbrella-shaped structure comprises a static head, a sealing bowl, a sealing cushion, a sealing ring, a cup cover, an upper cover, a cup body and a cup core, a blood inlet, a plasma outlet and the center pipe. The upper cover, the cup cover, the sealing ring, the sealing cushion and the sealing bowl are sequentially and movably installed and then the static head is installed in a sliding and matched mode. The plasma separating cup with the center pipe of the umbrella-shaped structure is characterized in that an umbrella-shaped face is arranged on the center pipe to form the center pipe of the umbrella-shaped structure. The umbrella-shaped face is arranged below the upper cover. A gap between the umbrella-shaped face and the upper cover forms a plasma overflowing channel. The top end of the center pipe of the umbrella-shaped structure is reliably welded with the static head. During production, only a pair of molds and a set of equipment are needed to form the center pipe of the umbrella-shaped structure in a one-time mode. In a general assembling procedure, only one-time welding needs performing to finish production. Producing a lower cover is not needed, production cost is reduced and production efficiency is improved.
Description
Technical field
This utility model relates to a kind of medical equipment, and particularly a kind of central canal is the separating plasma cup of beveled structure.
Background technology
The separating plasma cup is to utilize centrifugal principle to carry out one of important means of separating plasma in the modern biomedical engineering field, its ultimate principle is to utilize the sampled plasma machine to drive separating plasma cup high speed rotating, make compositions such as blood plasma in the separating plasma cup, hemocyte realize undamaged separation, regather plasma fraction, simultaneously, after separating end, the hemocyte that also needs not collect feeds back, the separating plasma cup is emptied, so that carry out collection, the separation of next circulation or finish whole capture program.Therefore in separating plasma cup inside, just design has the access way of blood and the overflow channel of blood plasma respectively, and the access way of blood is realized by the central canal in the separate cup.The central canal of present widely used separating plasma cup is to adopt following cover and the lower center tube comprise the upper channel part to produce injection molding respectively, assembles bonding before assembling again or the ultrasonic bonding mode forms separate cup blood access way central canal.This kind structure is being produced, is being prone to seepage, fracture equivalent risk in the use, has increased the input of artificial, adhesives or welding equipment simultaneously.
Summary of the invention
In view of the drawback of the separating plasma cup blood channel central canal mode of production at present commonly used, the purpose of this utility model is a kind of reduction central canal seepage of design, risk of breakage, the separating plasma cup that reduces production costs.
This utility model is realized above-mentioned purpose by following architectural feature:
This utility model is that a kind of central canal is the separating plasma cup of beveled structure, comprise static head, obturating cup, sealing gasket, sealing ring, bowl cover, last cover, cup, cup nuclear, the blood entrance, blood plasma outlet and central canal, last cover, bowl cover, sealing ring, sealing gasket, the static head of packing into is slidingly matched after the movable installation of obturating cup order, it is characterized in that having the umbrella shape face on the described central canal, form the central canal of beveled structure, the umbrella shape face is positioned at the below of cover, and the gap between the last cover forms the blood plasma overflow channel, beveled structure central canal top and the reliable welding of static head.
The separating plasma cup adopts the central canal of beveled structure, and cancel separating plasma cup use commonly used and covered the structure that part is formed the blood plasma overflow channel down, the deficiency of having avoided original separating plasma cup to exist, the realization blood separation is collected purpose.
In the production, the central canal of beveled structure only needs a secondary mould, a set of equipment, one-shot forming, only need once weld and to finish in the general assembly link, no longer need to produce down cover, and comprise following cover and the lower center tube injection moulding production respectively of upper channel, need carry out twice welding, twice assembling, all will cause certain waste to cost of labor, material cost, board equipment, reduce by a step welding process, and more can guarantee product quality, reduce consumption again, improved production efficiency.
Description of drawings
Fig. 1 is that this central canal is the separating plasma cup distribution structure sketch map of beveled structure.
Fig. 2 central canal is the profile of beveled structure.
Fig. 3 is central canal and static welding sketch map of beveled structure.
Among the figure:
9 glasss of nuclear of cover 7 umbrella shape faces 8 cups, 10 beveled structure central canals, 11 blood entrances, 12 pads, 13 blood plasma outlet on 1 static 2 obturating cups, 3 sealing gaskets, 4 sealing rings, 5 bowl cover 6
The specific embodiment
This utility model central canal be beveled structure the separating plasma cup as shown in Figure 1, by static 1, obturating cup 2, sealing gasket 3, sealing ring 4, bowl cover 5, on cover 6, umbrella shape face 7, cup 8, cup nuclear 9, beveled structure central canal 10, blood entrance 11, blood plasma outlet 13 constitute.Figure 2 shows that the central canal of beveled structure.With the difference of the central canal of original separating plasma cup be that a umbrella shape face 7 is arranged on the top of central canal.As shown in Figure 3, umbrella shape face 7 cooperates with last cover 6 below cover 6, and the gap between the two is the blood plasma overflow channel of separating plasma cup.On the last cover 6 respectively activity command install to be slidingly matched behind bowl cover 5, sealing ring 4, sealing gasket 3, the obturating cup 2 and pack static 1 into, again the central canal 10 of beveled structure is carried out ultrasonic bonding at pad 12 places and is fixed as one with static 1.So far, central canal is that the blood access way of separating plasma cup of beveled structure and blood plasma overflow path and namely finishes and produce assembling.It is assemblied in the central authorities of separating plasma cup 8, and namely finishing central canal of the present utility model is the production assembling of the separating plasma cup of beveled structure.
