Description

[0001] APPARATUS FOR INJECTING MEDICINE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug injection device, and more particularly, to a drug injection device that can inject a needle-cooled injection solution into a patient.

Drug infusion has been achieved by injecting the drug directly into the blood vessels or muscles, allowing a thin, sharp needle to penetrate through the skin. However, such a syringe has a problem that it may cause a secondary infection, which is caused by being stabbed by a contaminated needle as well as causing discomfort to the patients.

* Recently, "needle-less syringes" have been introduced that can inject injections under subcutaneous pressure with strong pressure.

"Needle-free syringes" utilize the pressure of gas or air, or Lorentz force, which acts on the charge moving in the magnetic field. At this time, the injection liquid was poured out with a strong pressure and passed to the blood vessels through the pores of the skin, so that the injection fluid could be injected into the affected area in a short time while reducing the patient's pain.

However, in the case of the " needle-less syringe " according to the conventional method, when injecting the liquid injection at a high pressure, the injection may be lost without being injected into the patient under the hypodermic route. There is a problem that it is difficult to keep it constant.

Further, there is a problem that the desired drug efficacy can not be obtained since the depth of injection of the injection liquid can not be controlled.

Therefore, there is a need for a syringe capable of injecting the injection fluid into the patient's subcutaneous tissue in a novel manner.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Also, the singular forms herein may include plural forms unless specifically stated in the text. It is noted that the terms "comprises" and / or "comprising" used in the specification are intended to be inclusive in a manner similar to the components, steps, operations, and / Or additions.

1 is a functional block diagram illustrating a drug injection device 100 according to an embodiment of the present invention.

A drug injection device 100 according to an embodiment of the present invention includes a syringe 200 and a cooling device 300. [ In addition, the injector 200 includes a pressurization unit 210, a fluid storage unit 220, and a coolant circulation unit 230.

However, it should be understood that those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope of the invention as defined in the appended claims. It will be appreciated that additional components may be included.

The pressurizing portion 210 generates high-pressure compressed air so that the injection liquid can be injected under the skin of the patient. The pusher 210 according to an embodiment of the present invention can be implemented as a propulsion system using a spring.

For example, after applying pressure to the cylinder using the elastic force of the spring, the injected fluid can be injected under the patient's skin by the force of the air that the cylinder pushes.

However, the method of implementing the pressing unit 210 is not limited to the above-described embodiment, and it is also possible to generate bubbles by using a laser to eject the injection liquid by using the pressure when bubbles are generated, So that the injected liquid is discharged by causing the fast magnetic field to push out the piston.

The injection liquid storage unit 220 is a space in which the injection liquid to be injected into the patient is stored. The injection liquid storage unit 220 is provided with at least one wedge-shaped frame so that the injection liquid can be cooled in a needle shape.

That is, the injecting solution storage part 220 serves as a cooling mold for cooling the injecting solution into a needle shape thinner from the upper end to the lower end. In addition, the injection liquid storage unit 220 may be formed of a stretchable material so that the cooled injection liquid can be discharged.

Accordingly, when a physical force or a high-pressure gas is generated by the pressurizing unit 210, the distal end of the injection liquid storage unit 220 is temporarily opened and the cooled injection liquid is discharged.

The process of injecting the injection liquid from the injection liquid storage unit 220 will be described in detail with reference to FIG.

Meanwhile, the injection solution storage unit 220 according to an embodiment of the present invention may be detachably attached to the syringe 200. A second infectious disease may occur when a single injection solution is injected into a plurality of patients using one injection solution storage unit 220 so that the used injection solution storage unit 220 can be replaced.

The refrigerant circulation unit 230 is a flow passage through which the refrigerant circulates. Specifically, the refrigerant circulation unit 230 is disposed adjacent to the injection liquid storage unit 220, and serves to circulate the refrigerant circulating through the cooling unit 300.

The coolant circulation unit 230 according to an exemplary embodiment of the present invention may be configured to enclose the injector solution storage unit 220.

The liquid refrigerant flowing in the cooling device 300 circulates around the liquid storage part 220 along the refrigerant circulation part 230 and absorbs heat. The refrigerant that has absorbed the surrounding heat and is converted to the gaseous state is returned to the cooling device 300 again.

The cooling device 300 provides a low-temperature refrigerant capable of freezing the injection liquid stored in the injection liquid storage part 220. The cooling device 300 according to an embodiment of the present invention may include a compressor (not shown), a condenser (not shown), and an evaporator (not shown).

The compressor compresses the gaseous refrigerant to high temperature and high pressure. The high-temperature and high-pressure refrigerant is transferred to the condenser and is liquefied and releases heat. The refrigerant in the liquid state in which the pressure is lowered circulates in the refrigerant circulation unit 230 and absorbs the heat inside the syringe 200 so that the ambient temperature is lowered.

As described above, since the coolant circulation unit 230 can be implemented to surround the periphery of the injection liquid storage unit 220, the coolant circulation unit 230 can circulate through the coolant circulation unit 230, It is possible to cool the liquid injected liquid stored in the liquid injecting section 220.

Since the injection liquid stored in the injection liquid storage unit 220 can be cooled down into a plurality of needles, the injected liquid is discharged to the outside of the syringe 200 by the high pressure gas generated by the pressurization unit 210 It is administered subcutaneously to the patient.

As described above, when a plurality of needles-cooled injections are subcutaneously administered to a patient, it is possible to achieve an effect of minimizing the amount of injections that may be lost when injecting a liquid injectate at a high pressure.

That is, it is possible to minimize the phenomenon that the injected liquid in the liquid state can not be injected subcutaneously and is repelled, or the phenomenon that the injected liquid does not reach the desired depth and spreads is minimized.

2 is a cross-sectional view of a syringe according to an embodiment of the present invention.

In this embodiment, the syringe 200 is a spring type syringe. The spring type injector 200 includes a trigger switch 210a, a spring 210b, and a piston 210c.

2, when the user operates the trigger switch 210a, the spring 210b returns to the original state, and the piston 210c is returned to the injection liquid storage unit 220, Direction.

On the other hand, a syringe storage part 220 is mounted at one end of the syringe 200 to store the syringe and cool the stored syringe into a plurality of wedge shapes.

A coolant circulating unit 230 is provided around the injecting liquid storing unit 220 to absorb heat from the stored injecting liquid to freeze the injecting liquid. Specifically, the coolant circulation unit 230 may be provided to surround the injection liquid storage unit 220 as shown in FIG.

Although not shown in FIG. 2, an insulator may be filled in the periphery of the injection liquid storage part 220 so that the injected liquid cooled by the external heat is not melted again.

In the above-described embodiment, the syringe 200 is of a spring type. However, the present invention is not limited thereto.

For example, in the case of using the compressed air, a compressed air cartridge (not shown) may be provided so that the expansion force of the compressed air is used as an energy source.

3 is a view for explaining a process of discharging the injection liquid stored in the injection liquid storage unit 220 by the user's operation.

When the user presses the trigger switch 210a, the elastic force of the compressed spring 210b pushes the piston 210c toward the injection liquid storage part 220. [

Accordingly, the compressed air in the syringe 200 is injected into the skin or tissue of the patient in a state where the compressed air is stored in the injected liquid storage part 220 in a cooled state.

Since the injection liquid storage unit 220 is made of an elastic material, when the injected liquid compressed by the compressed air is pushed out, the distal end of the injection liquid storage unit 220 is temporarily opened so that the injection liquid is discharged to the outside of the syringe 200 . The process of discharging the cooled injected liquid will be described in detail in FIG.

Thereafter, the user can repeat the administration of the injection liquid by refilling the elastic force of the spring 210b.

As described above, it is possible to minimize the amount of the injectable liquid which can be lost during the administration by administering the cooled injected liquid to the patient. In addition, by administering the injected liquid cooled at a low temperature, it is possible not only to alleviate the patient's pain but also to shorten the recovery time.

4 is a view for explaining a process of discharging a cooled injected liquid according to an embodiment of the present invention.

The injecting solution storage unit 220 according to an embodiment of the present invention may include a plurality of wedge shaped molds having an opening 221 at one end and a distal end 223 at which the other end is temporarily opened.

In addition, the injection solution storage unit 220 may be formed of a stretchable material. For example, the injection liquid storage part 220 may be made of a material such as rubber or silicone that is elastic and does not react with the injection liquid.

Accordingly, when a force for pushing out the injected liquid cooled by the inner pressure of the injector 220 is applied, one end of the injected liquid storage part 220 is opened to the left and right so as to be discharged into the injected liquid stored therein.

After the cooled injected liquid is discharged, one end of the injected liquid storage part 220 is closed again so that the injected liquid in the liquid state is not leaked to the outside even if injected into the injected liquid storage part 220.

5 is a view for explaining a method of filling an injection solution into the injection solution storage part according to an embodiment of the present invention.

When the injection liquid stored in the injection liquid storage unit 220 is used up, the injector 200 can be opened to fill the injection liquid. For this, a hinge part 260 for opening the syringe 200 may be formed on the outer surface of the syringe 200 according to an embodiment of the present invention.

The user can open the inside of the syringe 200 by rotating the upper end portion 250 and the lower end portion 240 of the syringe 200 at a predetermined angle around the hinge portion 260.

When the liquid storage portion 220 is exposed to the outside in the opened state, the user can fill the additional liquid injection.

5, when the injector 200 is implemented, it is necessary to fill the injector every time the injection fluid is injected. Therefore, when the injected injected fluid is injected, the fluid injected into the injector fluid storage part 220 may be automatically injected have.

6 is a view for explaining a syringe equipped with an injector replenishment unit according to an embodiment of the present invention.

The injector 200 according to an embodiment of the present invention may further include an injector replenishing section 270 as shown in FIG. A liquid injected liquid is stored in the injected liquid replenishing unit 270, and the injected liquid can be filled into the injected liquid storage unit 220.

The injecting liquid replenishing unit 270 according to the embodiment of the present invention is embodied as an elastic material so that when the injecting liquid storing unit 220 is empty when the user presses the injecting liquid replenishing unit 270, As shown in FIG.

However, the method of filling the injection solution using the injection solution replenishing unit 270 is not limited to the above-described method, and it is also possible that the injected solution stored in the injection solution replenishing unit 270 automatically senses that the injection solution storage unit 220 is empty And injected into the injection fluid storage unit 220.

6 illustrates an example in which the injector replenishing unit 270 is attached to the outside of the injector 200. However, the injector replenishing unit 270 may be implemented to be mounted inside the injector 200 have.

On the other hand, in the case where the same patient is to be injected several times, there is no fear of infection even if the injection solution storage unit 220 is repeatedly used. However, when the same injection solution storage unit 220 is used for different patients, There is a possibility of tea infection.

Accordingly, the injection solution storage unit 220 according to an embodiment of the present invention may be implemented in a detachable form.

7 is a view for explaining a method of replacing the injection solution storage unit 220 according to an embodiment of the present invention.

The injection liquid storage unit 220 can be filled with the injection liquid as well as the injection liquid storage unit 220 itself while the inside of the syringe 200 is opened around the hinge unit 260. [ As described above, when injecting an injection solution into a plurality of patients through the same injection solution storage unit 220, a secondary infection may occur due to a hygiene problem.

Specifically, the injected liquid storage part 220a may be removed and the new injected liquid storage part 220b may be mounted, and then the injected liquid may be filled and used.

In addition, the injector 200 according to another embodiment of the present invention can be independently used in a state where it is not connected to the cooling apparatus 300 since the injector solution storage unit 220 is detachable.

1, the syringe 200 is connected to the cooling unit 300 so that even if the injection liquid is filled in the injection liquid storage unit 220, the injection liquid is cooled in a needle shape 7, if the injector solution storage part 220 is replaceable as shown in FIG. 7, the injector solution that has already been needle-shaped according to the shape of the injector solution storage part 220 may be injected into the injector solution storage part 220, It may be mounted on the syringe 200 together with the syringe 220 and used.

In other words, the injector cooled in a needle shape according to the shape of the injector solution storage part 220 is mounted on the injector 200 together with the injector solution storage part 220 and injected to the patient, It is also possible to use another injection liquid storage unit 220 in which the cooled injection liquid is filled after the storage unit 220 is removed.

Therefore, it is possible to achieve an effect that the portability and usability of the syringe 200 can be increased.

8 to 10 are views showing a fluid storage unit according to various embodiments of the present invention.

As described above, since the injection solution storage unit 220 according to one embodiment of the present invention is implemented in a form detachable from the syringe 200, the injection solution storage unit 220 having a different shape may be mounted according to the purpose of use .

This is because the position to which the injection solution should be administered may vary depending on the efficacy of the injection solution to be injected into the affected part.

For example, when the drug has to reach deep into the dermis, the injection solution storage part 220 can be used, which can cool the injection solution into a long needle shape as shown in FIG.

On the other hand, when the drug is to be injected only into the epidermis of the patient, the injection solution storage unit 220 may be used, which can cool the injection solution into a needle shape having a short length as shown in FIG.

Alternatively, when the amount of the injection solution to be administered is large, as shown in FIG. 10, the injection solution storage part 220 having a narrow needle interval and a large number of needles may be used.

As described above, it is possible to efficiently inject the injectable solution by mounting the injectable solution storage part 220 according to the type, use, and the volume of the injectable solution to be injected, thereby maximizing the efficacy of the injectable solution. Can be achieved.

11 is a view for explaining a drug infusion apparatus according to another embodiment of the present invention.

1 to 10, a needles-cooled injected solution is administered to a patient through a syringe 200. However, the injector 200 may be directly administered without using a separate syringe 200.

The body portion 1100 includes a cylindrical injection-receiving portion 1200 having a wedge-shaped end and an opening at the other end. Therefore, when the injection solution is stored in the injection solution storage part 1200 and then frozen, a needle-shaped injection solution can be obtained.

The lid part 1300 is engaged with the body part 1100 so as to shield the opening of the injection liquid storage part 1200.

A grip portion 1320 may be formed on one side of the lid portion 1300 so that the user can easily handle the lid portion 1300. [ A plurality of protruding portions 1310 may be formed on the surface opposite to the surface on which the grip portion 1320 is formed so as to easily extract the cooled injected liquid from the liquid injecting portion 1200 of the body portion 1100.

The protrusions formed at the lower end of the lid portion 1300 will be described in detail in Fig.

11, after the injection liquid is filled in the injection liquid storage part 1200 formed in the body part 1100, the drug injection device 1000 is put in a separate cooling device with the lid part 1300 covered The filled injectate should be cooled.

However, the drug injection device 1000 according to an embodiment of the present invention may be implemented to further include a cooling device (not shown) and a coolant circulation unit (not shown).

At this time, the coolant circulation unit (not shown) may be configured so as to surround the periphery of the injection liquid accommodation unit 1200, as shown in FIG. The low-temperature refrigerant circulates in the refrigerant circulation part to absorb the surrounding heat, so that the injection liquid filled in the injection liquid accommodation part 1200 can be cooled.

As described above, when the drug injector 1000 is implemented to include a cooling device (not shown), the drug injector 1000 may be connected to a separate cooling device to cool the injected liquid filled in the injector housing 1200 It is possible to achieve an effect that user convenience can be improved.

12 is a view for explaining a lid of a drug infusion device according to an embodiment of the present invention.

As shown in FIG. 12, a plurality of protrusions 1310 may be formed at the lower end of the lid portion 1300 to be coupled with the injected liquid. When the lid part 1300 is separated from the body part 1100, the needle-shaped injected liquid should be coupled to the lower end of the lid part 1300 since the needle-shaped injected solution should be administered to the patient.

Therefore, the protrusion 1310 according to an exemplary embodiment of the present invention may have a latching protrusion 1311 formed at one end thereof to allow the injected liquid cooled in the injection liquid container 1200 to be coupled to the protrusion 1300.

The cooled injected liquid can be separated from the injection-receiving portion 1200 while being coupled to the lower end of the lid portion 1300 by the latching jaws 1311 of the projections 1310. [ Thereafter, the user is allowed to administer the injection solution coupled to the lid portion 1300 to the patient.

13 is a diagram for explaining a method of administering a cooled injection according to another embodiment of the present invention.
