Description

Technical Field

[0001] The present invention relates to a drug injection module including a sliding assisting unit. The drug injection module including the sliding assisting unit forms a plurality of protrusions on the outside of a cylinder, so that when inserted into a human body, uneven pressure is applied to the cylinder, thereby facilitating sliding between the human body and the cylinder. Background Art

[0002] Generally, in recent years, there are many cases where various fluids are injected into the human body for various purposes.

[0003] For example, there are: injecting cleaning fluid into the female genitals to clean them; using contraceptive liquid for contraception; injecting liquid medicine to treat hemorrhoids, sexually transmitted diseases, etc.; injecting lubricants during sexual intercourse, etc., and the uses are very diverse.

[0004] In this case, the inside of the human body's genitals and anus, etc., as the exposed mucous membrane, is very sensitive to external stimulation, and the mucous membrane is easily damaged or contaminated. Therefore, in order to inject the various liquids listed above, careful attention is required.

[0005] In the past, in order to improve the inconvenience of directly injecting the above liquid manually, a device for injecting liquid into the body was invented. Due to hygiene issues and difficulty in cleaning, such liquid injection devices are usually prepared as disposables, and therefore, are sold on the market in a state where liquid is pre-contained inside.

[0006] However, when a user injects liquid into the human body, the syringe must be inserted into the human body. In this case, there is a problem that pain may be caused by friction when the syringe is inserted into the human body.

[0007] In particular, when inserting into or ejecting from the human body, the human body will deform according to the shape of the cylinder and apply pressure to the cylinder, so the friction will increase. Since the connection between the inside and outside of the human body is blocked, it will be difficult to inject or eject the drug due to the pressure difference.

[0008] Furthermore, when inserted into the human body, the body muscles relax or contract due to human body signals and tension, making it difficult to insert and inject or discharge drugs.

[0009] Therefore, a new solution to this problem is needed. Summary of the invention

[0010] Technical issues

[0011] The technical problem of the present invention is to solve the problems mentioned in the background technology. The present invention provides a drug injection module including a sliding assist unit, that is, in an injection module containing drugs, a separate sliding assist unit is formed on the outer surface of the cylinder to make the pressure of the body on the cylinder uneven, and to form a separate connecting space to minimize the pressure difference between the inside and outside of the human body, thereby facilitating the sliding of the cylinder.

[0012] The technical problems to be solved by the present invention are not limited to the technical problems mentioned above, and ordinary technicians in the technical field to which the present invention belongs can clearly understand other technical problems not mentioned through the following description.

[0013] Technical Solution

[0014] The drug injection module of the present invention proposed to solve the technical problem includes: a cylinder having a relatively long length and a storage space capable of storing drugs therein, a discharge port for discharging the above-mentioned drugs being formed at the front end, and an opening at the rear end; a piston inserted into the interior of the above-mentioned storage space through the rear end of the above-mentioned cylinder, and sliding along the length direction to discharge the above-mentioned drugs; and a sliding assisting unit, which forms an uneven cross-sectional shape by making at least a part of the outer surface of the above-mentioned cylinder protrude or recessed, and produces a deviation in the pressure acting on the surface when contacting the body of the user; when the above-mentioned cylinder is inserted into the human body, the above-mentioned sliding assisting unit prevents the pressure of the human body acting around from becoming uniform, so as to facilitate sliding.

[0015] Furthermore, the slip assist unit may be extended along the longitudinal direction of the cylinder and have a predetermined length.

[0016] Furthermore, the above-mentioned sliding assisting unit may be formed in plurality along the circumference or length direction of the above-mentioned cylinder, with at least one being different.

[0017] Furthermore, at least one of the sliding assisting units may be formed to protrude along an outer surface of the cylinder so that a peripheral shape of the cylinder is uneven.

[0018] Furthermore, the slip assist unit may include: a protrusion protruding from the outer surface of the cylinder; and a blade portion extending from a protruding end portion of the protrusion, having a width relatively larger than that of the protrusion, and forming a separate connecting space between the protrusion and the cylinder.

[0019] Furthermore, the present invention is characterized in that the shape along the periphery to the edge of the blade portion is bent downward toward the cylinder and is spaced apart from the surface of the cylinder so as to be adjacent to the cylinder.

[0020] Furthermore, at least one of the slip assisting units may be recessed along an outer surface of the cylinder to make a peripheral shape of the cylinder uneven.

[0021] Furthermore, the present invention is characterized in that the width of the slip assist unit in the inner direction may be relatively larger than the surface of the cylinder.

[0022] Furthermore, the present invention is characterized in that the sliding assisting unit may form a communicating space communicating between the inside and the outside at least in a portion between the outer surface of the cylinder and the user's body.

[0023] Furthermore, the sliding assisting unit may form a pattern on the outer surface of the cylinder, and may form a plurality of protrusions protruding adjacent to each other.

[0024] Effects of the Invention

[0025] The drug injection module of the present invention includes a sliding assist unit, and a sliding assist unit is formed on the outer surface of the cylinder in the form of protrusions or depressions.

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the present invention, descriptions of known functions or structures will be omitted to clarify the gist of the present invention.

[0037] Furthermore, when describing the present invention, terms indicating directions such as front, rear, or upper / lower are recorded to enable technicians to clearly understand the present invention and indicate relative directions, and the protection scope of the present invention is not limited thereto.

[0038] First, refer to Figures 1 to 5 , the structure of an embodiment of a drug injection module including a sliding assist unit of the present invention is described in detail.

[0039] Figure 1 FIG. 1 is a diagram briefly showing a structure of an embodiment of forming a protrusion in a drug injection module including a sliding assist unit of the present invention. Figure 2 FIG. 2 is a diagram showing a state in which a drug injection module including a sliding auxiliary unit of the present invention is inserted into a human body. Figure 3 To show the pressure acting on Figure 2 Diagram of human body deformation under the state of cylinder.

[0040] and, Figure 4 To show the sliding assist unit Figure 3 The diagram shows the degree of pressure at each position caused by the protrusions in the cylinder. Figure 5 To show Figure 1 FIG. 4 is a diagram of the deformed morphology of the drug injection module including the sliding assist unit.

[0041] As shown in the figure, the drug injection module including the sliding assisting unit 300 of the present invention generally includes a cylinder 100 , a piston 200 and the sliding assisting unit 300 .

[0042] The cylinder 100 is long and has a receiving space 110 capable of receiving medicine therein. A discharge port 120 for discharging the medicine is formed at the front end, and the rear end is open for inserting a piston 200 described later.

[0043] Specifically, the cylinder 100 is a cylinder 100 in the form of a common syringe, and the medicine is filled in the housing space so that the medicine can be selectively ejected by a user's operation.

[0044] In this case, the cylinder 100 is extended in the front-to-back direction, and is generally curved, with a circular cross section, so that it can be inserted into the human body. Therefore, when inserted into the human body, it does not cause pain to the user. In addition, the transverse cross-sectional area of ​​the rear end of the cylinder 100 can be gradually enlarged to facilitate the insertion of the piston 200.

[0045] Furthermore, in the present embodiment, the discharge port 120 formed at the front end of the cylinder 100 may be provided with a cover to prevent the liquid contained before the user uses the body fluid insertion device from leaking through the discharge port 120 .

[0046] On the other hand, the piston 200 is inserted into the receiving space 110 through the rear end of the opening of the cylinder 100 in a manner that it can move forward and backward. That is, if the piston 200 is moved forward in a state where the piston 200 is inserted into the receiving space 110 in the cylinder 100, the liquid contained in the receiving space 110 will be pushed and ejected.

[0047] In this embodiment, although not shown in the drawings, a separate sealing component (not shown) is provided at the front end of the piston 200, so that the sealing component can be pushed forward and moved as the piston 200 moves forward.

[0048] Therefore, the front end of the piston 200 is inserted into the rear end of the cylinder 100 and can slide along the length direction, thereby pressurizing and ejecting the medicine.

[0049] As described above, the present invention is formed in the form of a syringe in which the cylinder 100 and the piston 200 are combined, and the medicine contained in the containing space 110 can be selectively discharged through the discharge port 120 formed at the front end.

[0050] On the other hand, the sliding auxiliary unit 300 is protruded or recessed on the outer surface of the cylinder 100. When the cylinder 100 is inserted into the human body S, the pressure distribution is uneven, thereby facilitating the insertion and discharge of the user. Moreover, a connecting space is formed inside and outside the human body S, thereby reducing the generation of pressure difference.

[0051] Specifically, the sliding assist unit 300 forms an uneven cross-sectional shape by making at least a portion of the outer surface of the cylinder 100 protrude or recess, so that a deviation in pressure acting on the surface occurs when the sliding assist unit 300 contacts the body of the user.

[0052] In this embodiment, as shown in the figure, a plurality of the sliding assisting units 300 are formed to protrude from the outer surface of the cylinder 100, so that the outer surface of the cylinder 100 has a non-circular shape and an uneven cross-sectional shape.

[0053] The sliding assisting unit 300 may be formed in a long slit shape along the length direction of the cylinder 100 , and as in an embodiment, a plurality of the sliding assisting units 300 may be radially and unevenly arranged.

[0054] That is, the sliding assisting unit 300 extends along the longitudinal direction of the cylinder 100 and has a predetermined length. A plurality of sliding assisting units 300 are formed along the periphery or the longitudinal direction of the cylinder 100 , and at least one of the sliding assisting units 300 has a different shape or size.

[0055] Thus, the sliding assisting unit 300 is formed to protrude from the surface of the cylinder 100, forming a non-uniform cross section, and when the cylinder 100 is inserted into the user's human body S, a pressure deviation is generated in the contact portion. Therefore, it is possible to prevent the pressure acting on the human body S along the periphery of the cylinder 100 from becoming uniform, and it is possible to suppress the friction generated when the cylinder 100 is inserted or ejected.

[0056] In particular, refer to Figure 3 and Figure 4 As shown in the figure, the cross-sectional shape of the human body S that is inserted into the body of the user is shown in a state where the sliding assist unit 300 is formed on the outer surface of the cylinder 100. Unlike the cylinder 100 with a uniform cross-sectional shape, the shape of the human body S that contacts the outer surface of the cylinder 100 actually forms an uneven shape due to the sliding assist unit 300.

[0057] In this case, the human body S can be in a shape that applies pressure to the cylinder 100. When the cylinder 100 has a circular cross section, the human body S also contacts the cylinder 100 in a circular shape and contacts the surface with a uniform pressure. However, as in the present invention, the sliding auxiliary unit 300 is formed on the outer surface of the cylinder 100, so that the human body S contacts the cylinder 100 in an uneven shape, and therefore, the protruding part and the non-protruding part contact the human body S with different pressures.

[0058] That is, when the portion of the outer surface of the cylinder 100 where the sliding assist unit 300 is formed and the portion where the sliding assist unit 300 is not formed respectively contact the human body S, they will contact with different pressures. Therefore, when inserting and ejecting the cylinder 100, the friction force between the various portions can cause sliding, thereby facilitating insertion and ejection.

[0059] In particular, in this embodiment, if Figure 4As shown, the sliding assisting unit 300 is configured to have a cross-sectional shape protruding in a curved form, and when in contact with the human body S, it can be divided into three regions A, B, and C.

[0060] Region A is the protruding portion of the sliding auxiliary unit 300 . When in contact with the human body S, the region is subjected to the greatest pressure. Due to the great pressure, the friction force generated in this portion during sliding is also the greatest.

[0061] Moreover, the area C is an area in the cylinder 100 where the sliding assist unit 300 is not provided. In this case, when the area C contacts the user's body S, the area C is subjected to pressure similar to that of the surrounding area, thereby causing friction to act.

[0062] On the other hand, region B is a region of the boundary portion of the cylinder 100 where the sliding assist unit 300 is formed, and is located between the positions where the protruding sliding assist unit 300 and the surface of the cylinder 100 contact the human body S. In this case, since it is a boundary region between the protruding portion and the non-protruding portion, it is a region where the pressure on the human body S is the smallest due to the height step difference, and thus the friction force is also the smallest. In addition, in region B, a portion that does not contact the human body S may be generated depending on the situation. In this case, the pressure difference can be suppressed by forming a connecting space connecting the inside and the outside of the human body S.

[0063] As described above, the drug injection module of the present invention includes the above-mentioned cylinder 100, the above-mentioned piston 200 and the above-mentioned sliding assist unit 300. It is not a simple syringe form, but the above-mentioned sliding assist unit 300 is used to make the pressure acting along the periphery become uneven when inserted into the human body S, thereby facilitating sliding, and the pressure difference can be prevented from being generated by additionally forming a connecting space connecting the inside and outside of the human body S.

[0064] On the other hand, referring to Figure 5 , shows the deformation form of the above-mentioned sliding auxiliary unit 300 in the above-mentioned drug injection module, and the basic form is a protrusion form.

[0065] However, the slide assisting unit 300 is not a simple protrusion, but a distal end portion is expanded, thereby forming a separate communication space at the bottom.

[0066] Specifically, as shown in the figure, the sliding assisting unit 300 includes: a protrusion 310 protruding from the outer surface of the cylinder 100; and a blade portion 320 expanding from the protrusion 310 to form a communicating space.

[0067] The protrusion 310 is formed in a shape similar to the above-mentioned embodiment with a predetermined width, and protrudes from the outer surface of the cylinder 100 so as to contact the user's body S. In addition, the blade portion 320 is expanded from the protruding tip portion of the protrusion 310 to form a width relatively larger than the protrusion 310. In this case, the blade portion 320 is expanded laterally from the tip portion of the protrusion 310, so that at least a part of the blade portion 320 is separated from the outer surface of the cylinder 100, thereby forming the above-mentioned communication space with the cylinder 100.

[0068] In this embodiment, the shape along the periphery to the edge of the blade portion 320 is bent toward the cylinder 100 and is arranged adjacent to the surface of the cylinder 100. That is, as shown in the figure, a mushroom shape is formed, and the communication space is formed between the cylinder 100 and the blade portion 320, so when the cylinder 100 is inserted into the human body S of the user, the air inside and outside flows through the communication space, thereby preventing the pressure difference from being generated.

[0069] Among them, the above-mentioned sliding auxiliary unit 300 extends along the length direction of the above-mentioned cylinder 100 and can form cross-sectional shapes with the same form. Different from this, it can form a circular or polygonal protrusion shape instead of a simple slit shape. The above-mentioned blade portion 320 can also be formed on both sides or radially along the width direction from the end portion of the above-mentioned protrusion portion 310 corresponding to each shape.

[0070] As described above, the first embodiment of the drug injection module of the present invention is understood. The above-mentioned sliding auxiliary unit forms a protrusion shape. When it contacts the human body S, the pressure acting on the surface of the cylinder 100 becomes uneven, so that slippage is easy to occur. At the same time, a connecting space is formed, thereby suppressing the pressure difference inside and outside the human body S, making the injection of the drug easier.

[0071] Next, refer to Figures 6 to 8 The drug injection module of the second embodiment of the present invention is described as follows.

[0072] Figure 6 FIG. 2 is a diagram showing a state in which the sliding assist unit 300 is in a groove form in the drug injection module including the sliding assist unit 300 of the present invention. Figure 7 To show Figure 6 FIG. 1 is a diagram showing the pressure effect caused by the deformation of the human body S when the cylinder 100 in the drug injection module is inserted into the human body S. Figure 8 To show Figure 6 FIG. 1 is a diagram showing a deformed form of a sliding assist unit 300 formed by a cylinder 100 of a drug injection module.

[0073] The drug injection module of the second embodiment of the present invention is similar in basic drug injection form, but different from the above content in that the sliding auxiliary unit 300 is not in a protrusion form, but in a groove form.

[0074] Specifically, as shown in the figure, the sliding assist unit 300 is recessed to a specified depth on the surface of the cylinder 100 and forms at least one portion that applies uneven pressure to the outer surface of the cylinder 100 when in contact with the human body S of the user.

[0075] As shown in the figure, the sliding auxiliary unit 300 is formed to extend along the length direction of the cylinder 100, has a predetermined length, and can be formed in plurality, and can be arranged spaced apart from the surface of the cylinder 100. In this case, as in the first embodiment, the sliding auxiliary unit 300 can be formed in a plurality of the same shapes, or at least a portion of the sliding auxiliary units can be formed in different shapes or sizes.

[0076] Furthermore, the sliding assisting unit 300 may be formed by being recessed at different depths on the surface of the cylinder 100 .

[0077] In this embodiment, the sliding auxiliary unit 300 extends along the length direction of the cylinder 100 to form a slit shape, and as shown in the figure, is recessed so that a part of it enters the interior of the recessed part when it contacts the user's body S.

[0078] As shown in the figure, when the human body S enters the recessed interior of the sliding assisting unit 300, the sliding assisting unit 300 is actually contacted with a relatively smaller pressure than the portion in contact with the outer surface of the cylinder 100. Therefore, when the cylinder 100 contacts the human body S of the user, slippage is easily generated by contacting in an uneven form.

[0079] Furthermore, a portion of the human body S that has entered the slide assisting unit 300 is not actually in contact with the human body, but is separated from the human body, thereby forming the communication space that allows the inside and outside of the human body S to communicate with each other.

[0080] As described above, when the sliding assisting unit 300 is in the groove form, it contacts the human body S contacting the surface of the cylinder 100 with uneven pressure, thereby making the friction force uneven, making sliding easier when inserting and removing the cylinder 100.

[0081] In addition, refer to Figure 8 Although the sliding assisting unit 300 is in the form of a groove, the width formed in the inner direction may be relatively larger than the surface of the cylinder 100 .

[0082] Specifically, the sliding assist unit 300 is formed long with a predetermined length and a predetermined width on the surface of the cylinder 100. The width L2 of the groove formed in the inner direction of the cylinder 100 is relatively large compared to the width L1 formed on the surface of the cylinder 100, so that even if the user's body S enters the interior of the sliding assist unit 300, a communication space can be ensured.

[0083] Generally, in the case of a body S having a specified level of elasticity, it is difficult to make the width of the body greater than the width of the entered portion even if pressure is applied when entering the groove. Therefore, even if the body S of the user enters the interior of the above-mentioned sliding assist unit 300, a width smaller than the width L1 is actually formed.

[0084] In the present embodiment, the sliding assist unit 300 is in a trapezoidal shape, so that the portion located on the surface of the cylinder forms a relatively small width L1. Therefore, even if the user's body S contacts the cylinder 100 and pressure is applied, the interior of the sliding assist unit 300 cannot be completely filled, and a portion of the connecting space can be maintained.

[0085] Next, refer to Fig. 9 Another deformation form of the drug injection module of the present invention is described as follows.

[0086] As shown in the figure, the sliding assisting unit 300 is not simply formed in the form of a protrusion, but forms a predetermined pattern on a partial area or the entire outer surface of the cylinder 100, and a plurality of protrusions protrude adjacent to each other.

[0087] Specifically, as shown in the drawings, the slide assisting unit 300 is formed of a plurality of curved protrusions that are adjacent to each other and form a specific pattern, and are formed on the outer surface of the cylinder 100 .

[0088] Among them, the above-mentioned sliding auxiliary unit 300 forms grooves dividing each protrusion on the outer surface of the above-mentioned cylinder 100, so when the above-mentioned cylinder 100 is inserted, the part that contacts the user's human body S is contacted in an uneven form. Not only that, a connecting space connecting the inside and outside of the human body S can also be formed through the groove.

[0089] Of course, unlike the illustrated sliding assist unit 300, it may be formed only on a portion of the cylinder rather than the entire surface, and the protrusions may have uneven shapes, sizes, heights, etc.

[0090] As described above, various embodiments of the drug injection module of the present invention are understood. The present invention includes the above-mentioned cylinder 100, the above-mentioned piston 200 and the above-mentioned sliding assisting unit 300. The above-mentioned sliding assisting unit 300 is used to contact the cylinder 100 with uneven pressure when inserting it into the human body S, thereby having the advantage of easy slippage.

[0091] As described above, specific embodiments of the present invention are illustrated and described, but the present invention is not limited to the described embodiments, and various modifications and variations can be made without departing from the concept and scope of the present invention, which is obvious to those skilled in the art. Therefore, these modified examples or variations should not be understood separately from the technical concept or viewpoint of the present invention, and the modified embodiments should be deemed to belong to the scope of the invention claimed by the present invention.
