Blood component separating and collecting device capable of adjusting extracorporeal circulation volume

Abstract

The invention discloses a blood component separating and collecting device capable of adjusting extracorporeal circulation volume, and relates to the technical field of separating and collecting equipment, the blood component separating and collecting device comprises a fixing plate, and the left side of the upper surface of the fixing plate is fixedly connected with a fixing box. Through mutual cooperation of the rotating disc, a threaded column, an arc-shaped supporting plate, a semi-annular sliding groove and an annular fixing block, the blood separation tank can be clamped and fixed, so that the stability of the blood separation tank can be guaranteed in the centrifugal process of the blood separation tank; through mutual cooperation of an electromagnetic valve, a plasma communicating pipe, a blood cell communicating pipe, a platelet communicating pipe, a whole blood input pipe, a blood connecting pipe and a flow dividing piece, the effects of collection and separation preparation of blood of a blood donor can be achieved at a time, and it is not needed to use different types of consumables for multiple times of operation; therefore, the problem that blood workers such as patients and mutual-aid blood donors need to be subjected to multiple times of vein puncture, so that the blood workers feel uncomfortable is solved.

Description

technical field [0001] The invention relates to a device for separating and collecting blood components, in particular to a device for separating and collecting blood components with an adjustable extracorporeal circulation volume. Background technique [0002] In the clinical work of the hospital, the collection, use or long-term storage of blood components such as plasma, platelets, and red blood cells are often involved, and blood components such as plasma, platelets, and red blood cells are mainly from the blood of patients and mutual donors. At present, there are still some defects and deficiencies in the use of the blood component separation and collection device. The specific areas that need to be improved are as follows: [0003] 1. The existing preparation and collection of blood components such as plasma, platelets, and red blood cells, or the replacement of pathological plasma, all require medical staff to use different types of consumables, and are mostly done ma...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a blood component separation and collection device with adjustable extracorporeal circulation volume, to solve the existing preparation and collection of blood components such as plasma, platelets and red blood cells, or the replacement of pathological plasma Treatment, etc., require medical staff to use different types of consumables, and most of them are done manually. In the process, it is necessary to perform multiple venous punctures on patients, mutual blood donors and other blood personnel, which increases the inconvenience of blood personnel. Moderate, and at the same time, the whole blood and blood components must be in contact with the outside air in the existing blood component separation process, which will easily lead to blood component pollution, bacterial and viral infections, and there are serious safety hazards
