Description

Technical Field

[0001] The utility model relates to the technical field of blood collection, in particular to a blood collector for hemodialysis care. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection to remove metabolic waste from the body and maintain electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The entire process is called hemodialysis.

[0003] For example, the Chinese patent with the announcement number: CN215017564U discloses a new blood collection device for hemodialysis care. It mainly solves the drawbacks of the existing guide needle that is easy to bend and fall off. The patent uses a guide groove to keep the test tube in a straight line when entering the installation cavity, avoiding the deviation of the installation sleeve and causing the guide needle to bend; the test tube is fixed in the connecting sleeve by a fixed block to ensure that the test tube will not fall off during sampling. Although the above patent solves the problem of the guide needle being easy to bend and fall off, it still has the following two drawbacks in actual operation:

[0004] 1. In the prior art, since most patients undergoing hemodialysis are uremia patients, after blood is collected from the patients, the needle and hose are directly discarded in the medical waste. Residual blood is easily retained in the needle. If the cleaning staff accidentally pierces the skin with the needle during handling, it is easy to cause blood virus infection, thereby increasing the workload of the cleaning staff;

[0005] 2. In the prior art, since blood sampling tests are conducted in batches, patient information is pasted on blood collection tubes via printed labels. If the labels accidentally come into contact with water or other liquids, the label information will be damaged and blurred, making it difficult to confirm the patient's identity, thereby increasing conflicts between doctors and patients.
