Description
The present invention relates to an injection device, and more particularly, to a medical injection device for preventing cells suspended in an injection solution from being settled or not floating and safely injecting the same evenly.
An injection device capable of injecting a liquid at a constant rate is used to inject the liquid through the veins of a human or animal. Here, the infusion solution is a mixture of a specific drug or other substance (including stem cells) in a saline solution (or a Ringer's solution or a nutrient solution capable of being administered to a human body), a saline solution (a Ringer's solution or a nutrient solution) , Liquid medicine in the form of a mixture of two or more kinds of drugs, and liquid medicine in emulsion or slurry form.
Stem cells are cells capable of self-proliferation and differentiation, and can be largely divided into embryonic stem cells and adult stem cells. In the case of double adult stem cells, it has been found that the stem cells are abundant in adipose tissue and bone marrow tissue of the body.
Cells that can be easily used in the current hospital include SVF cells (Stromal Vascular Fraction cells) obtained after enzymatic treatment after collecting adipose tissue, and stromal stem cells obtained after further purification of epidermal blood vessel fraction cells (ADSCs, Adipose derived stem cells), bone marrow-derived mesenchymal stem cells (BMMSCs) that can be obtained by culturing bone marrow fluid from bone marrow.
Recently, stem cell-based therapies have been developed and interest in stem cells has been increasing. Accordingly, a lot of equipment for facilitating the extraction of stem cells has been developed.
Stem cells are easily precipitated (precipitated) under water due to the difference in specific gravity between them after extraction or extraction. In addition, it has adhesion which is well adhered to plastic, and can be clumped together and solidified.
Because of the nature of these stem cells, if careful attention is not paid to injecting the extracted stem cells into the human body, significant cell loss may occur during the injection process, which may result in a reduction in therapeutic efficacy.
In addition, when the stem cells are administered in a loose state or at a high concentration, blood vessels may be blocked to cause thrombosis and allergy may be induced.
In addition, an additional process such as filtering is required for safety when an emulsion or a slurry type substance (a substance which is not dissolved in a cell or a solution) is input. There is a possibility that the effect will fall.
Despite these risks, the development of injection devices for injecting stem cells has been limited. In the case of administration using a conventional injection device, a device capable of controlling the rate at a constant rate and a device capable of administering the drug at a safe concentration by stirring the stem cells may cause a fatal medical accident.
Disclosure of Invention Technical Problem [10] Accordingly, the present invention has been made in order to solve the above problems of the prior art, and it is an object of the present invention to provide a stem cell, It is an object of the present invention to provide an injection device which can block the delivery of the drug, prevent the patient from being injured, and safely administer the injection solution at a constant speed or rate.
