An opening is formed at the rear side of the first cylinder 1100, and an external force can act on the first piston 1110 from the rear to deliver the drug to the front side.

Accordingly, the first piston 1110 inserted into the opening side is connected to the front gasket 1200 to seal the drug filled in the accommodation space 1001 so that it does not leak to the rear side, and the first rod 2210 of the automatic injector from the rear side. ) to provide power.

The gasket 1200 installed in front of the first piston 1110 seals the accommodation space 1001 backward. The gasket 1200 is made of a material having a predetermined flexibility and has a shape capable of sealing by being in close contact with the inner wall surface of the first cylinder 1100 at the outer periphery.

In addition, in order to minimize the remaining amount after injecting the drug into the first cylinder 1100, the second cylinder 1120 is formed through the central portion of the first piston 1110 and the gasket 1200. It has a structure in which the second piston 1113 is inserted from the rear of the cylinder 1120, the inner diameter of the second cylinder 1120 is the same as the inner diameter of the connection part 1130, and the second cylinder 1120 and the connection part ( 1130 are arranged on a straight line with each other so that when the gasket 1200 advances, it can communicate with the connecting portion 1130, and at this time, when the second piston 1113 advances inside the second cylinder 1120, it The tip portion has a length that can approach the tip portion of the connecting portion 1130.

Here, the second piston 1113 is formed as a square body in cross section, and similarly, the second cylinder 1120 is also formed as a hollow part whose cross section is square to accommodate the second piston 1113, The outer circumferential surface of the piston 1113 is in airtight contact with the inner circumferential surface of the second cylinder 1120, or a separate gasket is attached to the tip of the second piston 1113 so that the drug filled in the front of the second piston 1113 is transported to the rear. to prevent leakage.

The rear portion of the first piston 1110 has a cylindrical shape, and a first key 1112 protrudes outward from one side or both sides thereof, and a first key groove ( 1114) is formed, so that the first piston 1110 is detachably coupled to the first rod 2210 that is drawn out or drawn in from the adapter 2100, and the first piston 1110 is detachably coupled to the first rod 2210 that is drawn in or drawn out. The second piston 1113 is detachably coupled to the second rod 2220.

2-1) Receiving prescription information of a specific patient

When a doctor treats a patient and then inputs prescription information through the computer 5000, the prescription information is transmitted to the cradle 4000 through the Wi-Fi network or the RoLa network, and the cradle 4000 receives the received Bluetooth Low Energy It is transmitted to the handpiece 2000 through a local area network such as (BLE).

As mentioned above, the prescription information includes the patient's name, date of birth, type and dose of drug, date and time of prescription, ID for designating a specific auto-injector, and the like.

The BLE communication unit 2510 of the handpiece 2000 receives the prescription information transmitted from the holder 4000 and provides it to the controller 2500, whereby the controller 2500 receives the prescription information included in the prescription information and It checks if the ID of the matches.

This is to reconfirm the completion state after drug injection by transmitting prescription information of a specific patient to an autoinjector designated by a doctor.

Therefore, when it matches their ID, the prescription information is stored in the storage unit 2520, the display unit 2540 is turned on and the prescription information is displayed through the display unit 2540, and the operation standby mode becomes

As a result, according to the lighting state of the display unit 2540, the medical personnel can check the operation standby mode of the specific auto-injector, and can check the prescription information displayed through the display unit 2540, and the medical personnel can check the patient's name It is possible to prevent errors of injecting wrongly into other patients by directly confirming the patient's date of birth and date of birth.

2-2) Installation of pre-filled syringe

After the patient's prescription information is received, the medical personnel mounts the adapter 2100 on the front end of the handpiece unit 2000, and mounts the prefilled syringe 1000 on the adapter 2100.

To mount the prefilled syringe 1000, the first rod 2210 and the second rod 2220 are fastened by a key fastening method. When the first key 1112 is inserted into the second key groove 2211, The second key 2221 is automatically inserted into the first key groove 1114, and in this state, when the disposable injection 1000 is rotated 90°, the coupling is easily performed.

Since the prefilled syringe 1000 must be replaced for each injection considering the safety of vaccine injection, etc., the above coupling method has a very simple structure.

The ring-shaped adapter 2100 has a structure in which the rear portion of the first cylinder 1100 is inserted and fixed, and since this structure is similar to that of the one-sided adapter, a structural description thereof will be omitted.

Thereafter, the control unit 2500 drives the reading unit 2600, and accordingly, the drug information stored in the storage unit 1300 of the prefilled syringe 1000 is read, and the controller 2500 reads the read drug information for prescription. It is determined whether the information matches the drug prescription information, and the injection mode is performed only when the information matches.

Of course, if the code information does not match, the display unit 2540 displays the inconsistency information and the motor driving unit 2530 is not operated.

2-3) Drug injection

As described above, when the prefilled syringe 1000 is mounted on the adapter 2100 and other medical devices are connected and mounted on the prefilled syringe 1000, the control unit 2500 is controlled by an input of the button unit 2310 from a medical person. Injects the drug inside the accommodation space 1001 into the patient by controlling the motor driving unit 2530 so that the first piston 1110 and the second piston 1113 can move forward at the same speed.

Thereafter, when the advancement of the first piston 1110 and the second piston 1113 is completed, the control unit 2500 continues to advance the second piston 1113 so that the drug inside the second cylinder 1120 is transferred to the connection space ( 1002) is injected.

In addition, as the second piston 1113 advances from the inside of the connection space 1002 to the front end of the connection part 1130, the drug inside the connection space 1002 is injected, and a part of it remains only inside the needle.

That is, the remaining amount of the drug is minimized as the drug filled in the accommodation space 1001 remains only inside the other medical device, that is, the needle.

When the injection is completed, the exhausted prefilled syringe 1000 is removed from the adapter 2100 and the unused prefilled syringe 1000 is replaced and used. This removal may be performed in the reverse order of the mounting step.

The handpiece unit 2000 injects the drug while controlling the injection amount and speed of the drug.

As shown in FIG. 7, a typical LDS (Low Dead Space) syringe has a pillar-shaped insertion protrusion 131 protruding forward at the front end of the piston 130, so that the insertion protrusion 131 is connected to the connecting portion during injection. Although it is inserted into the connection space 121 of 120 to reduce the remaining amount, the connection space 121 is removed by the insertion protrusion 131 before the drug accommodated in the accommodation space 101 escapes into the connection space 121. By being closed, smooth injection is not performed and the injection speed is slowed down.

In addition, even when there is a free space between the outer diameter of the insertion protrusion 131 and the inner diameter of the connection space 121, injection of the injection solution can be slightly faster, but there is a problem in that the drug remains in the free space.

However, when the injection is performed according to the structure of the present invention, the residual amount of the drug is not left at all or is minimized.

3) Transmission of injection information

On the other hand, since the object of the present invention is to increase efficiency so that it can be applied to fields requiring rapid and mass inoculation, such as vaccines, it is preferable that the inoculation amount of each automatic injector is centrally managed. To this end, the present invention may have a function of converting, storing, and transmitting information about inoculation, such as the number or amount of injection of a drug and inoculation completion information of an inoculator, into data. Accordingly, the control unit 2500 stores the inoculation information in the storage unit 2520 for each inoculation time, converts it into a database, and manages the cumulative management.

Therefore, the transmitted inoculation data can be transmitted to the smartphone or tablet computer of the inoculator on which the application is installed through Bluetooth, or the inoculation information can be transmitted to the central management server unit and the inoculator's smartphone via a relay network such as a Wi-Fi network.

This relay network will be able to transmit inoculation information to the central management server and the smartphone via a mobile communication network such as LTE and 5G as well as a Wi-Fi network.

4) Information management

In addition, through a smartphone, the person to be treated, that is, a patient or an inoculation person, a reservation holder, a hospital user, etc., can visualize and view information on vaccination, current count, reservation status, etc. By providing management information such as the number of inoculations and the operation status of the auto-injector, it has the basis of the Internet of Things.

That is, the control unit 2500 stores information such as the number of daily inoculations, the cumulative number of inoculations, and the operating state of the autoinjector in the storage unit when injecting drugs using an autoinjector, and the low power Bluetooth ( By providing information by BLE), the cradle 4000 transmits it to the computer 5000 or the central management server through a mobile communication network such as Wi-Fi, LTE, or 5G, and also transmits it to a medical practitioner's smartphone.

Of course, the handpiece unit 2000 and the medical practitioner's smart phone may be paired with each other to receive information directly.

When the application is installed on the medical practitioner's smartphone and executed, the initial screen is displayed as shown in FIG. 8, and when the Bluetooth icon displayed on the screen is touched, the BLE communication function is activated and pairing with the handpiece unit 2000 .

Since the model name of the handpiece part 2000 displayed in the application is 'I-JECT', if you touch the 'View iExec details' button, you will be moved to the mode selection screen as shown in FIG. When the 'Select' button is touched after touching, management information such as the number of daily inoculations, the cumulative number of inoculations, the amount of inoculation, and the operation status of the autoinjector is transmitted from the autoinjector.

At this time, when a request from the handpiece unit 2000 occurs, the smart phone transmits the current date and time information to the handpiece unit 2000, and the handpiece unit 2000 transmits the current date and time information to the handpiece unit 2000. The number of inoculations is counted, the number of inoculations and the amount of inoculation are accumulated in the storage unit 2520, and then transmitted to the smartphone and the remote central management server unit.

The inoculation amount can be confirmed by a separate sensor when one inoculation is completed, but if an accurate vaccine is inoculated by the above process, it can be easily calculated by prescription information.

In addition, since various information such as standby state, charging state, air removal, loading, and injection of the handpiece part 2000 is transmitted to the smart phone in real time, the operating state of the handpiece part 2000 can be recognized immediately.

10 shows a state in which the operating state of the handpiece unit 2000 is displayed through a smartphone application, and the battery remaining amount of the handpiece unit 2000, the serial number, the amount of vaccine used, the number of inoculations per day, and the cumulative inoculation The number of times, operation status, etc. are displayed.

The automatic injector of the present invention can be managed centrally by setting an identifier such as a serial number for each device, registering the identifier at the hospital using the product, and managing the central management server unit at the time of product purchase contract.

That is, as shown in Figure 11, when the production year, production month, ID, and production number of the auto-injector are entered in the application of the smartphone, and then the 'generate serial number' button and the 'register device number' button are entered, the central management server The automatic injector is transmitted to the unit and the auto-injector is registered, and then all information of the registered auto-injector is transmitted to the central management server unit, thereby enabling integrated management.

According to the configuration as described above, it is possible to update the status of vaccinated persons in real time, and for example, it is possible to aggregate vaccination information by time, region, item, and hospital. Accordingly, since the expiration date and usage statistics of vaccines are easily derived, and this becomes the basis for maintaining an appropriate inventory, the efficiency of global management can be dramatically improved.

Having described specific parts of the present invention in detail above, it is clear to those skilled in the art that these specific descriptions are only preferred embodiments, and the scope of the present invention is not limited thereby. something to do.

Accordingly, the substantial scope of the invention will be defined by the appended claims and their equivalents.
