Hereinafter, a docking system having a key-lock structure for a medical device according to the present invention will be described in detail.

When administering drugs into the patient's blood vessels, various medical devices are required. Typically, an angiocatheter to secure the patient's vascular route, a bag containing fluids or drugs to be administered, and a fluid set connecting them. I need a back. In addition, if necessary, a drug injection filter for removing fine glass powder or the like that may be included in the drug to be injected, a needleless connector to enable drug injection without a needle, or the like may be used.

Since the medical devices are composed of several parts, in order to actually administer the drug to the patient, a process of connecting the medical devices to each other (docking) is required. This docking is achieved by inserting the male-docking portion 2 of the connecting portion of one medical device (cancer-medical appliance) into the female-docking portion 1 of the connecting portion of another medical appliance (cancer-medical appliance).

In the present invention, in order to prevent an error in drug administration and blood transfusion in the docking, a groove 11 is provided in an intaglio in the arm-docking part 1, and a raised protrusion 12 in the male-docking part 2 is provided. It is provided, and the groove 11 and the protrusion 12 are technically characterized in that they are configured to correspond to each other. Therefore, if even one error occurs during the preparation of drug administration, docking itself becomes impossible and drug administration is physically impossible, and through this, medical personnel and patients can recognize and correct the error.

Furthermore, in the present invention, the groove 11 and the protrusion 12 are designed in a unique shape determined according to the type of drug. The native form is not necessarily limited to this, but may be the code name of the drug. In particular, it is preferable that the eigenmorphism be adjusted based on the code promised within the integrated system.

The technical features are shown in Fig. 1A, and Fig. 1A shows that the number of grooves 11 and protrusions 12 of the docking system is four, respectively, but the number of grooves 11 and protrusions 12 is thus It is not limited and can be determined according to needs. In addition, the angles between the grooves 11 or the projections 12 and the sizes of the grooves 11 and the projections 12 are sufficient as long as they correspond to each other, and can be determined as necessary.

5A and 5B are examples of an alphabet-based shape system and a number-based shape system designed to shape the code name of a drug composed of alphabets and numbers, respectively. The groove 11 and the protrusion 12 may be configured in the shape of alphabets and numbers of FIGS. 5A and 5B. For a specific example, if the code name of the drug vincristine is set to <IVCRN013>, it will have the shape of a docking connector as shown in FIG. 6B.

Since the docking connector according to the present invention can identify the drug code name through the cross-section of the connector as shown in FIG. 6B, it is possible to check which drugs are administered or whether the prescribed drugs are properly prepared by the docking connector itself.

In addition, the docking connector according to the present invention may be provided with display lines 21 arranged in a straight line with each other at an angle at which the male docking part 2 can be inserted into the female docking part 1. A medical person using the docking system can quickly perform docking through the display line 21.

On the other hand, although the "connection" of the above-described cancer-medical device is generally formed directly on the cancer-medical device, it may be formed indirectly in the form of an arm-adapter 31. Further, the "connection" of the veterinary device is generally formed directly on the veterinary device, but may be formed indirectly in the form of a male-adapter 32.

If the "connecting part" is formed directly on the medical device, configurations such as the female docking part 1 and the male docking part 2 are formed directly on the medical device. That is, the female docking part 1 and the male docking part 2 are directly formed at the ends of medical devices such as angiocatheter, infusion set, needleless connector, and drug injection filter.

If, the "connector" can be formed indirectly in the form of an adapter to the medical device. In this case, the female-docking portion (1) and the male-docking portion (2) are not formed directly at the ends of the medical device, and the female-docking portion (1) and the male-docking portion (2) are medical devices. It may be formed in a separate adapter coupled to the end of.

On the other hand, as shown in Fig.7, the adapter is wrapped with a flexible tube 33 or the like so that the connection part is not exposed outside in normal times, and when the adapter is coupled to a female-medical device or a veterinary-medical device, the flexible tube ( 33) It is desirable that the connection is exposed to the outside. This is because, if the connection portion formed in the adapter is exposed outside, it is possible to use an anomaly in which the male and female structures of the female-adapter 31 and the male-adapter 32 are previously fastened.

In addition, if the "connection part" of the medical device is indirectly formed through an adapter or the like to the medical device, it is preferable to configure the cancer-medical device and the veterinary-medical device not to be directly connected without the adapter.

In addition, it is preferable that the docking system is manufactured by a 3D printer.

Hereinafter, it will be described how the docking system of the present invention prevents incorrect administration of drugs through a workflow in which drugs are prescribed and injected into a patient.

In a conventional docking system, drugs are administered to a patient through the following workflow (A1 to A4).

A1. Prescribing medication by your doctor, check the above prescription by nurse and prepare tools

A2. To secure the patient's vascular route, prepare an angiocatheter, disinfectant cotton, and fixation tape to visit the patient to secure the vascular route

A3. Prepare the drug and connect the appropriate infusion set to the bag containing the drug.

A4. Visit the patient with the prepared drug and inject the drug after confirming that the drug was prescribed for the patient

Through the steps A1 to A4, it is confirmed whether the drug prescribed to the patient is being properly prepared, so-called double check. On the other hand, in each step of the workflow, the medical practitioner repeatedly checks whether there is an error through the medical record and the conversation with the patient, but it is practically impossible to record all the processes of such simple repetition check.

On the other hand, in the docking system of the present invention, the drug is administered to the patient through the following workflow (B1 to B4).

B1. Prescribing drugs by the doctor in charge and prescribing a key-lock structure that has a unique form according to the type of drug, and the nurse confirms the above prescription and prepares tools

B2. To secure the patient's vascular route, visit the patient to secure the vascular route by preparing angiocatheter, disinfectant, and fixing tape having the above-described lock structure.

B3. Prepare a drug, and connect the infusion set with the unique key structure to the bag containing the drug.

B4. Visit the patient with the prepared drug and inject the drug after confirming that the drug was prescribed for the patient

If an error occurs in any one of the steps B1 to B3, the combination of the key-lock structure is impossible in step B4, and the administration of the drug becomes impossible, thereby preventing the incorrect administration of the drug from the source and physically.

In other words, since all steps B1 to B4 use connectors having a unique shape according to the type of drug, there is an effect that double checks are possible at each step, so that a quadruple check (four double checks) can be realized. have. In addition, in the workflow using the present invention, each double check process remains in a physical form (intrinsic form of a connector), so that the process of simple repetition confirmation is actually recorded.

The present invention can be used without limitation in medical devices used by combining cancer-medical devices and water-medical devices, and in particular, angiocatheter (FIG. 2), needleless connector (FIGS. 3a, 3b), and drug injection filter (Figure 4) can be used.
