Hereinafter, a docking system having a key-lock structure used in a connection portion of a needleless connector according to the present invention will be described in detail.

When administering a drug into a patient's blood vessel, various medical devices are required. Representatively, an angiocatheter to secure the patient's blood vessel route, a bag containing the fluid or drug to be administered, and a fluid set connecting them I need a back. In addition, if necessary, a filter for drug injection to remove 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, a process (docking) of connecting the medical devices to each other is necessary to actually administer the drug to the patient. This docking is achieved by inserting the number-docking portion 2 of the connection portion of one medical device (water-medical device) into the arm-dock portion 1 of the connection portion of another medical device (cancer-medical device).

The present invention, in order to prevent drug administration errors and transfusion errors in the docking, the arm-dock portion (1) is provided with a groove (11) at an intaglio, and the water-dock portion (2) is embossed (12). It is provided and characterized in that the groove 11 and the projection 12 are configured to correspond to each other. Therefore, if any error occurs during the preparation of drug administration, docking itself becomes impossible, and drug administration becomes physically impossible, thereby enabling medical personnel and patients to recognize and correct errors.

Furthermore, in the present invention, the groove 11 and the projection 12 are designed in a unique form determined according to the type of drug. The intrinsic form, although not necessarily limited to this, may be the code name of the drug. In particular, it is desirable to allow the eigenform to be adjusted based on the promised code in the integrated system.

The technical features are shown in FIG. 1A, and in FIG. 1A, the number of grooves 11 and protrusions 12 of the docking system is shown to be four, respectively, but the number of grooves 11 and protrusions 12 is thereby It is not limited and can be determined as needed. In addition, the angles between the grooves 11 or the protrusions 12 and the size of the grooves 11 and the protrusions 12 are sufficient as long as they correspond to each other, and can be determined as necessary.

5A and 5B are examples of alphabet-based shape systems and number-based shape systems designed to shape code names of drugs consisting of alphabets and numbers, respectively. The groove 11 and the protrusion 12 may be configured in the shape of alphabets and numbers in 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 code name of the drug through the cross section of the connector as shown in FIG. 6B, it is possible to confirm which drug is being administered or the prescribed drug is correctly prepared by the docking connector itself.

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

On the other hand, the "connecting portion" of the above-described cancer-medical device is generally formed directly on the cancer-medical device, but may be formed indirectly in the form of the female-adapter 31. In addition, the "connection" of the water-medical device is generally formed directly on the water-medical device, but may be formed indirectly in the form of a water-adapter 32.

If the "connecting portion" is formed directly on the medical device, a configuration such as the arm-docking part 1 and the male-docking part 2 is directly formed on the medical device. That is, the arm-docking part 1 and the water-docking part 2 are directly formed at the ends of medical devices such as an angiocatheter, an infusion set, a needleless connector, and a filter for injecting drugs.

If, the "connection" can be formed indirectly in the form of an adapter to the medical device. In this case, the arm-docking part 1 and the male-docking part 2 and the like are not directly formed at the distal end of the medical device, and the arm-docking part 1 and the male-docking part 2 are medical devices. It may be formed in a separate adapter that is coupled to the end.

On the other hand, as shown in FIG. 7, the adapter is wrapped with a flexible tube 33, etc., so that the connection part is not normally exposed outside, and the flexible tube (when the adapter is coupled to a cancer-medical device or a water-medical device) 33) It is desirable that the gaps open to reveal the connecting portion. This is because, if the connecting portion formed in the adapter is normally exposed outside, it is possible to use anomalies in which the male and female structures of the female-adapter 31 and the male-adapter 32 are fastened in advance.

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

In addition, the docking system is preferably made of a 3D printer.

Hereinafter, a description will be given of how the docking system of the present invention prevents misadministration of drugs through a workflow in which drugs are prescribed and injected into a patient.

In the conventional docking system, the drug is administered to the patient through the following workflows A1 to A4.

A1. Prescribing medications from your doctor, confirming the prescriptions above, and preparing tools

A2. To secure the patient's vascular route, prepare angiocatheters, disinfecting pads, and fixing tapes to visit the patient to secure the vascular route

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

A4. Visit the patient with the prepared drug, confirm that the infusion drug is prescribed for the patient, and inject the drug

Through the steps of A1 to A4, it is confirmed whether the drug prescribed to the patient is correctly prepared, so-called double check is performed. On the other hand, at each step in the workflow, the medical practitioner repeatedly checks for errors through medical records and conversations with the patient, but it is practically impossible to record all of these simple repetition checks in the record.

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

B1. The prescription of the drug by the doctor in charge, the prescription of the key-lock structure having the unique form according to the type of the drug, confirmation of the prescription by the nurse, and preparation of the tool

B2. In order to secure the vascular route of the patient, an angiocatheter, disinfecting pad, fixing tape, etc. having the above-described lock structure is prepared to visit the patient to secure the vascular route

B3. Prepare the drug and connect the fluid set with the key structure of the unique type to the bag containing the drug

B4. Visit the patient with the prepared medication, confirm that the infusion medication is prescribed for the patient, and inject the medication

If an error occurs in any one of the steps B1 to B3, it is impossible to combine the key-lock structure in the step B4, so that administration of the drug is impossible, and through this, erroneous administration of the drug can be prevented by nature.

In other words, since all of the B1 to B4 steps use a connector having a unique shape according to the type of drug, there is an effect that a double check is possible in each step, and 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 (a unique form of the connector), so that the process of confirming a simple iteration is substantially recorded.

The present invention can be used without limitation in a medical device used by combining a cancer-medical device and a water-medical device, in particular, an angiocatheter (FIG. 2), a needleless connector (FIG. 3A, 3B), and a filter for drug injection (FIG. 4).
