Hereinafter, a key for medical instruments according to the present invention will be described in detail with respect to the docking system of the lock structure.

When administering drugs into a patient's blood vessels, various medical devices are needed, typically an angiocatheter to secure the patient's blood vessel route, a bag containing the fluid or drug to be administered, and an infusion set connecting them. etc are needed. In addition, if necessary, a filter for drug injection that removes fine glass powder that may be included in the injected drug, a needleless connector that enables drug injection without a needle, etc. may be used.

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

In the present invention, in order to prevent drug administration errors and blood transfusion errors in the docking, an intaglio groove 11 is provided in the female-docking unit 1 and an embossed projection 12 is provided in the male docking unit 2 It has a technical feature that the groove 11 and the projection 12 are configured to correspond to each other. Therefore, if even one error occurs in the process of preparing for drug administration, docking itself becomes impossible and drug administration becomes physically impossible, through which the medical personnel and the patient can recognize and correct the error.

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

The technical characteristics are shown in FIG. 1A, and in FIG. 1A, the number of grooves 11 and projections 12 of the docking system is shown as four, respectively, but the number of grooves 11 and projections 12 is thus It is not limited and may be determined as needed. In addition, the angle formed 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 needed.

5A and 5B are an example of an alphabet-based shape system and a number-based shape system designed to shape the code name of a drug consisting of alphabets and numbers, respectively. The groove 11 and the protrusion 12 may be configured in the shape of alphabets and numbers shown 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 check which drug is administered or whether the prescribed drug is properly prepared with the docking connector itself alone.

In addition, the docking connector according to the present invention male-to the docking unit (1) - when the angle at which the docking unit 2 can be inserted, the display lines 21 arranged in a straight line with each other may be provided. A medical person using the docking system can quickly dock through the display line 21 .

On the other hand, the aforementioned "connection part" of the cancer-medical device is generally formed directly on the cancer-medical device, but may be formed indirectly in the form of the arm-adapter 31 . In addition, the "connection part" of the male-medical device is generally formed directly on the male-medical device, but may be formed indirectly in the form of the male-adapter 32 .

If the "connection part" is formed directly on the medical device, the female-docking part (1) and the male-docking part (2) and the like are directly formed 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 instruments such as angiocatheters, infusion sets, needleless connectors, and filters for drug injection.

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

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 normally, and when the adapter is coupled to a female-medical device or a male-medical device, the flexible tube ( 33), it is preferable that the connection part is exposed to the outside. This is because, if the connection part formed on the adapter is exposed outside even in normal times, it is possible to use anomalous use of pre-fastening the male and female structures of the female-adapter 31 and the male-adapter 32 .

In addition, if the "connection part" of the medical device is indirectly formed to the medical device through an adapter or the like, it is preferable to configure so that the female-medical device and the male-medical device are not directly connected without the adapter.

In addition, the docking system is preferably manufactured by a 3D printer.

Hereinafter, through a workflow in which a drug is prescribed and injected into a patient, how the docking system of the present invention prevents misadministration of the drug.

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

A1. Prescribing medications by your doctor, checking the above prescriptions by the nurse and preparing tools

A2. To secure the blood vessel route of the patient, prepare angiocatheter, disinfectant swab, fixing tape, etc. to visit the patient and secure the blood vessel 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, check that the injected drug is the one prescribed for the patient, and then inject the drug

Through the steps A1 to A4, it is confirmed that the drug prescribed to the patient is being prepared correctly, so-called double check is made. Meanwhile, in each step of the workflow, medical personnel repeatedly check for errors through medical records and conversations with patients, but it is practically impossible to record all of these simple and repeated verification processes.

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. Prescribing the drug by the doctor in charge and prescribing a key-lock structure with a unique shape according to the type of drug, confirming the prescription by the nurse and preparing the tool

B2. In order to secure the blood vessel route of the patient, prepare an angiocatheter, disinfectant swab, fixing tape, etc. having the unique type of lock structure to visit the patient and secure the blood vessel route

B3. Prepare the 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, check that the injected drug is the one prescribed for the patient, and then inject the drug

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, making it impossible to administer the drug, and through this, misadministration of the drug can be fundamentally and physically prevented.

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

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