Description

Blood collection separator Technical Field The utility model relates to the technical field of blood collection, in particular to a blood collection and separation device. Background The blood collection and separation cup is a common consumable for collecting blood components and raw material plasma and separating components in the current blood transfusion industry, and a cup body, a cup core and a stationary head of the separation cup are key components for realizing the separation of the blood components. The working principle is that the centrifugal force generated by the high-speed rotation of the separating cup is used for separating blood components, and the static head is used for keeping fixed so as to realize the inflow and outflow of blood in the separating cup. Wherein, the static head is fixed on the cylinder cover of the blood component separator, the separating cup body is fixed on the rotating base of the blood component separator, and the rotating base drives the separating cup body to rotate at high speed. At present, the blood inlet direction and the blood component outlet direction of the static head of the separation cup are horizontal directions, so that the connection assembly of a blood inlet and a blood outlet and a consumable blood circulation pipeline is inconvenient on the use site of the separation cup, and the automatic assembly is difficult to realize. Meanwhile, in the prior art, the capacity of the cup body is relatively fixed, and different capacities are inconvenient to collect. In view of this, the present application has been made. Disclosure of utility model The utility model aims to provide a blood collection and separation device, which is convenient for the automatic assembly of a separation cup and a consumable blood circulation pipeline by improving the structure of the static head, and simultaneously, the improvement of the connection structure between the static head and an upper cover as well as the improvement of the connection structure between the static head and a lower cover as well as the change of the matching modes of an elastic element, a fixed sealing element and a rotary sealing element, thereby being convenient for the automatic assembly in the production process of the separation cup and improving the production efficiency. The utility model is realized by the following technical scheme: The blood collection and separation device comprises a separation cup, wherein the separation cup comprises a cup body, a cup cover, a static head, an upper cover and a lower cover, and is characterized in that a blood inlet and a blood outlet at the top of the static head are vertically arranged, and the upper cover and the lower cover are connected with the bottom of the static head; the lower cover is sleeved in the upper cover, the upper end of the lower cover is communicated with the blood inlet to form a blood inflow channel, and the space between the upper cover and the inner wall of the lower cover is communicated with the blood outlet to form a blood outflow channel; The liquid inlet end of the blood inflow channel enters the lower cover from the end A and penetrates through the cup cover to extend into the bottom of the cup body; The liquid outlet end of the blood outflow channel passes through the cup cover and is positioned at the cup mouth along the top of the cup body, enters the gap between the upper cover and the lower cover, and flows out through the position B. According to the separating cup, the blood inlet and outlet of the static head are improved from the horizontal direction to the vertical direction, so that when the separating cup is produced, after the static head is clamped and fixed through equipment, consumable pipelines can be vertically and downwards arranged above the static head, the assembling is more convenient, automatic assembly can be performed by utilizing automatic equipment, and the consumable pipelines do not need to be manually arranged like the existing separating cup. Further, the device also comprises a fixing clamp, wherein the bottom of the fixing clamp is provided with a clamping groove matched with the shape of the top of the static head, and the fixing clamp can be mounted and dismounted with the static head through up-and-down movement or flip movement. The outer wall of the joint of the stationary head and the stationary clamp is in a conical surface or a cylindrical surface, and the clamping groove of the stationary clamp is matched with the stationary head through the conical surface or the cylindrical surface. The utility model improves the static head blood inlet and outlet to be vertical, thus the fixed clamp can be improved into an integral structure, the static head is clamped and fixed by the up-and-down movement of the fixed clamp or the flip movement of the fixed clamp, the operation is more convenient, and the static head can be fixed rapidly.
