Blood circulation promoter for hematopoietic stem cell collection

Abstract

The invention discloses a blood circulation promoter for hematopoietic stem cell collection. The blood circulation promoter comprises a fixing frame, a clamping plate, an air cushion, an adjusting frame, a shell, an indicating lamp, a storage battery, a first wiring terminal, a second wiring terminal, a sliding groove, a conductive slider, a spring, an airbag, a circulating hole, a first air pipe,a three-way valve, a second air pipe, an inflatable airbag, a third air pipe, an air cushion belt and a heating pad. The blood circulation promoter is powerful in function and simple to operate; through inflation-type pressurizing design inside, convenience can be brought to exposing blood vessels of an arm of a donor, so that puncture success rate is increased greatly, and clinical practicability is improved; by arranging a heating mechanism inside, blood circulation of the donor can be promoted, so that effect of subsequent hematopoietic stem cell collection can be improved. To sum up, great safety and convenience can be brought to the donor, burden of medical staff is relieved effectively, and the blood circulation promoter is conducive to clinical popularization and application.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood circulation promoting instrument for collecting hematopoietic stem cells. Background technique [0002] At present, there are two methods for clinical hematopoietic stem cell collection. The first method is that medical staff puncture the donor’s ilium to collect hematopoietic stem cells in the bone marrow. You will feel pain. The second is to use scientific methods to effectively mobilize the hematopoietic stem cells in the bone marrow and other parts to release a large amount into the peripheral blood, collect them from the donor's arm veins, and separate the hematopoietic stem cells through a machine, leaving the rest The blood is returned to the donor, so the method is the same as a normal blood donation. [0003] According to the above, when collecting the second type of hematopoietic stem cells, some women or donors with thin blood vessels are difficult to ...

AI Technical Summary

Problems solved by technology

[0003] According to the above, when collecting the second type of hematopoietic stem cells, some women or donors with thin blood vessels are difficult to expose during the puncture process due to the thin blood vessels, which greatly affects the follow-up. In addition, the traditional method can not achieve the promotion of blood circulation of patients, which affects the release speed of hematopoietic stem cells into the peripheral blood. In view of the above defects, it is necessary to design a blood circulation promoting instrument for hematopoietic stem cell collection.
