Abstract

The present invention comprises an intelligent injection device including a tube connection part for seating a tube connected to a drug pack, a motor that drives a pressure pump to pump the drug from the drug pack and discharge it through the tube, a tube information extraction part that scans one side of the drug pack to extract manufacturing information and extracts information on the tube connected to the drug pack based on the manufacturing information, and a control part that controls the motor's rotation information according to the tube information so that a precise amount of drug is automatically injected. Accordingly, the present invention has the advantage of automatically injecting a precise amount of drug by changing the motor's rotation information according to the thickness of the tube connected to the drug pack.

Description

Intelligent Injection Apparatus and Method of Injecting Drug The present invention relates to an intelligent injection device and a method of operation thereof, and more specifically, to an intelligent injection device and a method of operation thereof that allows the amount of drug administered to be automatically changed so that a precise amount of drug is administered according to the circumference of a tube. Pharmaceutical products (including large and small molecule agents, hereinafter referred to as "drugs") are administered to patients in various ways for the treatment of specific medical indications. Regardless of the method of administration, caution must be exercised when administering drugs to avoid adverse effects on the patient. For example, care must be taken not to administer more of the drug than is safe for the patient. This sometimes requires considering the amount of the given dose and the time frame in which the dose is delivered in relation to previous doses or doses of other drugs. Furthermore, care must be taken not to inadvertently administer the wrong drug to the patient, or a drug that has decomposed due to its aging period or storage conditions. All of these considerations may be conveyed in guidelines associated with specific drugs or drug combinations. However, these guidelines are not always strictly followed due to errors, such as human error. This can cause adverse effects on the patient or lead to inappropriate drug administration, for example, insufficient or excessive doses of medication administered for specific medical indications. Additionally, the drug delivery device may be operational but unable to complete its operation or successfully administer the drug. These failures to complete operation and unsuccessful administration, respectively, may pose a risk of harm to the patient if the problem is not promptly identified. Regarding the manner in which a drug is administered to a patient, various forms of administration may be used. For example, these forms of administration may include parenteral, inhaled, oral, ophthalmic, nasal, topical, and suppository forms of one or more drugs. The dosage form can be administered directly to the patient through a drug delivery device. There are numerous different types of drug delivery devices commonly available for the delivery of various dosage forms. In the case of a drug administration device in which a specific amount of drug from a drug pack is automatically pumped and injected into a patient's body through a tube, the thickness of the tube varies depending on the manufacturer of the drug pack, so the nurse had to manually input the thickness of the tube. However, on one side of the drug pack, a large amount of data (i.e., manufacturer information, drug information, etc.) is written in small print, making it difficult to find information regarding the thickness of the tube, and there is a disadvantage that it must be entered individually every time the drug pack is changed. FIG. 1 is a drawing for explaining an intelligent injection device according to an embodiment of the present invention. FIG. 2 is a block diagram illustrating the internal structure of an intelligent injection device according to one embodiment of the present invention. FIGS. 3 and FIGS. 4 are drawings for illustrating a dot code coded on a drug pack according to an embodiment of the present invention. FIG. 5 is a flowchart illustrating an embodiment of the operation method of an intelligent injection device according to the present invention. FIGS. 6 and FIGS. 7 are exemplary diagrams for explaining a motor control process according to tube thickness in accordance with an embodiment of the present invention. The aforementioned objectives, features, and advantages are described in detail below with reference to the attached drawings, thereby enabling those skilled in the art to easily implement the technical concept of the present invention. In describing the present invention, detailed descriptions of known technologies related to the present invention are omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.
