Description

A oozing blood monitoring devices for hemodialysis branch of academic or vocational study

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to oozing blood monitoring devices for hemodialysis branch of academic or vocational study.

Background

Hemodialysis is one of the kidney replacement treatment modes of acute and chronic renal failure patients, and is characterized in that blood in vivo is drained to the outside of the body, and the blood and electrolyte solution with similar body concentration are arranged inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, so that the substance exchange is carried out through dispersion and convection, the metabolic waste in the body is removed, and the electrolyte and acid-base balance are maintained; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis.

Currently, the most commonly used vascular access for hemodialysis patients is an internal arteriovenous fistula. The internal fistula puncture needle needs to be retained in a blood vessel for 4-5 hours during dialysis treatment, and the occurrence rate of blood leakage at the puncture point of the internal fistula is higher (about 6-12%) due to the facts that anticoagulant is used for dialysis treatment, the blood vessel wall of the internal fistula is thin, the blood flow is large, scar tissues are formed by long-term puncture, the elasticity of the blood vessel is poor, and the arm of a patient is involuntarily shaken during dialysis treatment; in the current practical operation, when hemodialysis treatment is performed on a hemodialysis patient, whether the blood seeps from a puncture point is checked is mainly judged by regularly observing the puncture point of the internal fistula and the personal feeling and self-check of the patient by a hemodialysis room nurse through naked eyes. Therefore, regularly checking whether the puncture point of the internal limb fistula of the patient is oozed by blood is one of the most important work contents of the hemodialysis room nurse, and finding out the oozing in time is very critical. If a small amount of blood seepage is not found and treated in time to cause the needle to slide off, the blood loss of a patient in one minute can reach 200ml, and if the blood seepage is not found and treated in time, the life of the patient can be endangered; the existing monitoring device for the blood seepage condition of the puncture part has simpler function, and in addition, the protection performance after the blood seepage is also poorer.

The state intellectual property office discloses a utility model patent that publication number is "CN 201445525U" 5.5.2010, a simple "dialysis puncture oozing blood monitor" has been proposed, dialysis puncture oozing blood monitor, by alarm (2), three kinds of subassemblies of monitoring head (1) and central display (5) constitute, alarm (2) for dialysis puncture oozing blood monitor are with wire (4) connection U-shaped or semi-ring monitoring head (1), alarm (2) and central display (5) wireless connection, an independent work alarm unit is constituteed to per two monitoring heads (1) and an alarm.

The monitor can basically detect the condition of the oozing blood, but at present, as more and more patients are used or a nurse deals with problems for other patients, the blood loss amount can reach hundreds of milliliters in tens of seconds when the patient is not busy, particularly in the case of needle removal, and the life of the patient can be endangered.

Therefore, there is a need to find a simple device or method that can detect bleeding and achieve simple emergency hemostasis.
