A portion of the syringe 30 may be inserted into the cover body 110 . Specifically, by inserting at least a portion of the needle unit 32 including the needle unit (N), it is possible to prevent the needle unit (N) from being contaminated by external factors or being damaged by external impact (Fig. 7a to 7c). The cover body 110 may have a space into which the needle unit 32 can be inserted, and in this case, the cover body 110 may have various shapes such as a cylinder and a polygonal pillar. However, hereinafter, for convenience of explanation, the embodiment in which the cover body 110 has a cylindrical shape having a space therein will be mainly described.

The coupling unit 120 may couple the syringe cover 10 to the syringe 30 . In one embodiment, the coupling unit 120 is disposed on one end of the cover body 110, the cover body 110 and the syringe 30 can be coupled. In this case, the coupling part 120 may have an insertion hole 121 . The coupling part 120 may have various shapes, such as a cylinder, a polygonal pillar, etc. provided with the insertion hole 121 . However, hereinafter, for convenience of description, an embodiment in which the coupling part 120 has a circular column shape in cross section will be mainly described.

As an embodiment, the coupling part 120 may be detachably disposed with the cover body 110 . However, the present invention is not limited thereto, and as another embodiment, the coupling part 120 may be formed integrally with the cover body 110 .

The insertion hole 121 may be formed to pass through the coupling portion 120 , and a portion of the syringe 30 may be inserted into the syringe cover 10 through the insertion hole 121 . In this case, the insertion hole 121 may communicate with the inner space of the cover body 110 .

At least a portion of the coupling portion 120 may be changed in width along the longitudinal direction (a direction parallel to the central axis C1 or the X-axis direction) of the coupling portion 120 . In this case, a portion of the coupling portion 120 may have a different width from other portions of the coupling portion 120 .

The insertion end 122 of the coupling part 120 may increase in width in a direction spaced apart from the cover body 110 (eg, the -X-axis direction in FIG. 2 ). Here, the insertion end 122 may mean an end located in a direction in which the needle unit 32 is inserted among the ends of the coupling unit 120 . In this case, the area of the insertion end 122 may be expanded toward the -X-axis direction of FIG. 2 . As a result, the area of the region where the needle unit 32 starts to be inserted increases, so that it is possible to facilitate the insertion of the needle unit 32 into the insertion hole 121 .

In addition, the insertion hole 121 may be formed to be narrower in area from the coupling part 120 to the cover body 110 . Accordingly, the insertion end 122 and the inside thereof, as shown in FIG. 3 , are formed to be inclined toward the cover body 110 , so that the needle unit 32 is inclined after being inserted into the insertion hole 121 . It can be guided to the inner space of the cover body 110 by moving along the insertion end 122 .

3 is a cross-sectional view illustrating a coupling part according to an embodiment of the present invention. Referring to FIG. 3 , the coupling part 120 may include a protrusion. In this case, the protrusion may be disposed on the inner circumferential surface of the insertion hole 121 to protrude toward the center of the insertion hole 121 (eg, the central axis C1 ).

The protrusion may extend along the circumferential direction of the inner circumferential surface of the insertion hole 121 . In this case, the protrusion may have a ring shape extending along the inner circumferential surface of the insertion hole 121 so that both ends of the protrusion meet each other. However, the present invention is not limited thereto, and the protrusion is provided with a plurality of protrusions, and the plurality of protrusions may be disposed to be spaced apart from each other along the circumferential direction of the inner circumferential surface of the insertion hole 121 .

At least one protrusion may be provided. As an embodiment, a plurality of protrusions may be provided. In this case, the number of protrusions is not limited, but for convenience of explanation, the coupling part 120 will be described mainly in an embodiment in which the first protrusion part a1 and the second protrusion part a2 are provided. .

The plurality of protrusions are disposed on the inner circumferential surface of the insertion hole 121 and may be spaced apart from each other. Specifically, the first protrusion a1 and the second protrusion a2 may be disposed to be spaced apart from each other. In this case, the first protrusion a1 may be disposed closer to the insertion end 122 of the coupling part 120 , and the second protrusion a2 may be disposed closer to the cover body 110 .

The plurality of protrusions may protrude at different protrusion distances. Specifically, the first protrusion a1 and the second protrusion a2 may protrude toward the central axis C1 of the insertion hole 121 . At this time, the first protrusion distance r1 at which the first protrusion a1 protrudes toward the central axis C1 and the second protrusion distance r2 at which the second protrusion a2 protrudes toward the central axis C1 are may be different from each other.

As an embodiment, as the second protrusion a2 protrudes more toward the central axis C1 of the insertion hole 121 than the first protrusion a1 , the second protrusion distance r2 is the first protrusion distance r1 . ) can be longer than In this case, there may be a difference of r between the first protrusion distance r1 of the first protrusion a1 and the second protrusion distance r2 of the second protrusion a2 . Due to the difference in the protrusion distance between the first protrusion a1 and the second protrusion a2, the first protrusion a1 and the second protrusion a2 each have a fixing protrusion B of the needle unit 32 to be described later. ) can provide different fixing forces.

The first protrusion (a1) and the second protrusion (a2) have a surface facing the needle unit 32 insertion direction (hereinafter, front), and a surface opposite to the direction in which the needle unit 32 is inserted (hereinafter, rear surface). may include

The front and rear surfaces of the first protrusion a1 may have curved surfaces. Thereby, when the needle unit 32 moves in the insertion direction (X-axis direction), the fixing protrusion (b) to be described later moves along the curved front surface of the first protrusion (a1), so that the first protrusion (a1) can easily pass through. In addition, by applying a force to the syringe 30 in the opposite direction (-X-axis direction) to the insertion, if necessary, the fixing protrusion (b), which was fixed by the first protrusion (a1), is inserted in the opposite direction (-X-axis direction) By moving along the rear surface of the first protrusion a1, the fixed state by the first protrusion a1 may be released.

The front surface of the second protrusion a2 may include a curved surface. In this case, the rear surface of the second protrusion a2 may not include a curved surface, and for example, the rear surface of the second protrusion a2 may include a flat surface. In this case, when the needle unit 32 moves further in the insertion direction (X-axis direction) past the first protrusion a1, the fixing protrusion b moves along the curved front surface of the second protrusion a2. , can easily pass through the second protrusion (a2). Thereafter, the fixing protrusion (b) passing through the second protrusion (a2) is caught on the flat rear surface of the second protrusion (a2), so that it may not be able to re-move in the opposite direction of insertion (-X-axis direction). In this way, the second protrusion (a2) is formed in a different shape on its front and back surfaces, so that the needle unit 32 and the syringe 30 including the same can be completely coupled in a state inserted into the syringe cover 10. .

The grip part 130 may be a part that moves the syringe cover 10 or grips the syringe cover 10 to insert and couple it to the syringe 30 . In this case, the holding part 130 may be disposed on either the cover body 110 or the coupling part 120 . However, the present invention is not limited thereto, and a part of the gripping part 130 may be disposed on the cover body 110 , and the remaining part of the gripping part 130 may be disposed on the coupling part 120 .

The grip part 130 may include a bent part 131 . The bent part 131 may be disposed at one end of the grip part 130 as an embodiment. In this case, the bent portion 131 may be bent in a direction facing the outside of the cover body 110 (eg, -X-axis direction in FIG. 2 ). In this case, the bent part 131 may be a part gripped by the user to use the syringe cover 10 .

The bent part 131 may be disposed to be spaced apart from at least one of the cover body 110 and the coupling part 120 , and in this case, the bent part 131 is either the cover body 110 or the coupling part 120 and They may be spaced apart by the first distance L1a. In this case, the connection part 132 may be disposed between the bent part 131 and the cover body 110 or between the bent part 131 and the coupling part 120 .

Specifically, one end of the connection part 132 may be connected to at least one of the cover body 110 and the coupling part 120 , and the other end of the connection part 132 may be connected to the bent part 131 . In this case, the connection part 132 is from one end of the connection part 132, toward the other end of the connection part 132, in a direction perpendicular to the longitudinal direction (X-axis direction in FIG. 2) of the cover body 110 (in FIG. 2 - in the Y-axis direction). Accordingly, when the syringe 30 is inserted into the syringe cover 10, the bent portion 131 may not be disposed on the same line as the insertion direction (X-axis direction) of the needle portion (N). That is, the bent portion 131 is spaced apart from the needle portion (N) and disposed to deviate from the needle portion (N), whereby the user's hand is punctured by the needle portion (N) in the syringe 30 insertion process (that is, , cut) can be prevented.

The first distance L1a may mean a distance at which the bent part 131 is spaced apart from the cover body 110 or the length of the connection part 132 . At this time, the first distance L1a may be changed according to the shape or size of the syringe body 31 or the needle unit 32 of the syringe 30 coupled to the syringe cover 10 .

The bent part 131 may be disposed in parallel with the cover body 110 . Specifically, the bent portion 131 may be disposed parallel to the longitudinal direction (X-axis direction) of the cover body 110 or may be disposed parallel to the central axis C1 of the cover body 110 . Accordingly, the bent portion 131 may be disposed parallel to the syringe 30 or the needle unit 32 inserted into the cover body 110 . Due to the bent portion 131 disposed in parallel as described above, the user can check whether the syringe 30 and/or the needle portion N is inserted into the syringe cover 10 to be flat with the central axis C1.

A portion of the bent part 131 may protrude more than the coupling part 120 to the outside of the coupling part 120 . As an embodiment, one end of the bent part 131 may protrude more than the coupling part 120 in a direction away from the coupling part 120 (-X-axis direction in FIG. 2 ). Here, one end of the bent portion 131 that protrudes more than the coupling portion 120 is the bent portion 131 disposed on the side opposite to the syringe body 31 when the syringe cover 10 is coupled with the syringe 30 . It can be an end.

Specifically, one end of the bent portion 131 may protrude further in the opposite insertion direction (-X-axis direction) than the insertion end 122 by the second distance L1b. Thereby, when the needle unit 32 is inserted into the syringe cover 10, one end of the bent portion 131 gripped by the user is disposed so as to be adjacent to the syringe body 31 rather than the needle portion N, so that the needle portion It is possible to prevent being stabbed by (N). At this time, the second distance L1b may be changed according to the shape or size of the syringe body 31 or the needle unit 32 of the syringe 30 coupled to the syringe cover 10 .

The gripper 130 may have a concave portion 131a concavely formed in a groove shape on its surface. Due to the concave portion 131a , when the user grips the gripper 130 , it is possible to prevent the user's hand from sliding from the gripper 130 . As an embodiment, the concave portion 131a may be provided on at least one surface of the bent portion 131 . In this case, the concave portion 131a may be disposed on both surfaces of the bent portion 131 to be concave toward the inner side of the bent portion 131 (Z-axis direction or -Z-axis direction in FIG. 1 ). . In this case, the area of the concave portion 131a may be smaller than the area of the surface of the bent portion 131 in which the concave portion 131a is formed.

As another embodiment, an anti-slip member (not shown) may be disposed in the concave portion 131a. In this case, the anti-slip member may apply a frictional force to the gripping user's hand, and in this case, the anti-slip member may be, for example, a rubber plate. As such, by disposing the anti-slip member in the concave portion 131a, the effect of preventing the user's hand gripping the grip portion 130 from slipping while the syringe cover 10 is in use can be improved.

The gripper 130 may include a transverse protrusion 133 . As an embodiment, the transverse protrusion 133 may be disposed on the bent portion 131 . Specifically, the transverse protrusion 133 may be disposed at an end of the bent portion 131 connected to the connecting portion 132 . In this case, the transverse protrusion 133 may protrude in a direction perpendicular to the longitudinal direction (X-axis direction) of the bent portion 131 .

Specifically, one end of the protruding ends of the transverse protrusion 133 may protrude from the bent section 131 in the Z-axis “? The other end may protrude in the -Z axis direction from the bent portion 131. In this case, both protruding ends of the transverse protrusion 133 protrude the same protrusion distance, so that both protruding ends of the transverse protrusion 133 are symmetrical to each other. At this time, the transverse protrusion 133 may extend along the longitudinal direction (X-axis direction) of the bent part 131 and be formed to have the same length as the bent part 131. In this case, the transverse protrusion ( 133) can shield between the bent part 131 and the cover body 110. Thereby, the needle part N inserted into the cover body 110 is prevented from moving to the bent part 131, so that the user can protect the hands of

4 is a perspective view showing a gripper according to another embodiment of the present invention. Referring to FIG. 4 , the gripper 130 may further include a longitudinal protrusion 134 .

The longitudinal protrusion 134 may be disposed on the connection part 132 . As an embodiment, the longitudinal protrusion 134 is at the end of the needle unit 32 and opposite to the needle unit 32 among the ends of the connection part 132 when the needle unit 32 of the syringe 30 is inserted into the syringe cover 10. can be placed. In this case, the longitudinal protrusion 134 may protrude in a direction perpendicular to the longitudinal direction (Y-axis direction) of the connecting part 132 .

Specifically, one end of the protruding ends of the longitudinal protrusion 134 protrudes from the connecting part 132 in the Z-axis "? In this case, both protruding ends of the longitudinal protrusion 134 protrude the same protrusion distance, so that both protruding ends of the transverse protrusion 133 may be symmetrical to each other. It extends along the longitudinal direction (Y-axis direction) and may be formed to have the same length as the connecting portion 132. In this case, the longitudinal protrusion 134 may shield between the connecting portion 132 and the insertion hole 121. By this, even when the user uses the syringe cover 10 while holding the connection part 132, the needle part N is prevented from moving to the connection part 132, thereby protecting the user's hand. .

Meanwhile, the protrusion distance of the longitudinal protrusion 134 is the same as the protrusion distance of the lateral protrusion 133 , so that the longitudinal protrusion 134 may be formed to be continuous with the transverse protrusion 133 . By the transverse protrusion 133 and the longitudinal protrusion 134 , it is possible to completely shield the gripping part 130 from the insertion region into which the needle part N is inserted, thereby preventing cuts caused by the needle part N. can be prevented from occurring.

5 and 6 , the syringe cover 20 according to another embodiment of the present invention may include a cover body 210 , a coupling part 220 , and a gripping part 230 . At this time, the cover body 210 extends along the central axis (C2), the syringe 30 or the needle unit 32 therein may be provided with a space to be inserted.

The coupling part 220 may have an insertion hole 221 , and in this case, the insertion hole 221 may communicate with the space inside the cover body 210 . However, unlike the coupling portion 120 of the syringe cover 10 of the above-described embodiment, the insertion end of the coupling portion 220 may have a constant width along the longitudinal direction (X-axis direction) of the coupling portion 220. .

The gripping part 230 may include a bent part 231 and a connection part 232 , and in this case, a concave part 231a may be provided on at least one surface of the bent part 231 . In this case, the bent portion 231 is disposed to be spaced apart from the cover body 210 by a first distance L2a, and one end of the bent portion 231 has a second distance in the -X-axis direction than the coupling portion 220 ( It may protrude further by L2b). However, unlike the grip portion 130 of the syringe cover 10 of the above-described embodiment, the grip portion 230 may not include a transverse protrusion and/or a longitudinal protrusion.

Except for the differences as described above, the specific features of each component included in the syringe cover 20 are the same as or similar to those of the syringe cover 10 described above, so a redundant description thereof will be omitted.

Figure 7a is a cross-sectional view showing a state before the syringe is inserted into the syringe cover in the syringe set according to an embodiment of the present invention. 7B is a cross-sectional view showing a first fixed state in which the syringe is inserted and fixed in the syringe cover in the syringe set of FIG. 7A. And, FIG. 7c is a cross-sectional view showing a second fixed state in which the syringe is inserted and fixed in the syringe cover in the syringe set of FIG. 7a.

7A to 7C , the syringe set 1 may include the syringe covers 10 and 20 and the syringe 30 . At this time, the specific features of the syringe cover are the same or similar to the above-described, syringe cover 10 according to an embodiment of the present invention, or the syringe cover 20 according to another embodiment of the present invention, and thus overlapping description is to be omitted.

The syringe 30 may refer to a generally used syringe used for injecting a substance into or discharging a substance from the body, and may include a disposable syringe. In general, the syringe 30 may include a syringe body 31 and a needle unit 32 . In this case, the syringe body 31 may contain a substance to be injected into the body.

The needle unit 32 may include a needle part (N) and a fixing protrusion (b). In this case, the needle part (N) may be directly inserted into the body and serve as a passage through which the material accommodated in the syringe body 31 is injected into the body.

The fixing protrusion (b) may be disposed on the needle unit (32). The fixing protrusion (b) may protrude outward from the outer peripheral surface of the needle unit 32 in the radial direction of the needle unit 32 . In this case, the fixing protrusion (b) may include a surface (hereinafter, front) facing the syringe body 31, and a surface (hereinafter, rear) opposite to the front of the fixing projection (b). In this case, the front surface of the fixing protrusion (b) may be formed as a flat surface, and the rear surface of the fixing projection (b) may be formed as an inclined surface inclined toward the needle part (N) from the flat front surface.

The fixing protrusion (B) may be fixed by the first protrusion (a1) or the second protrusion (a2) when the syringe 30 is inserted into the syringe cover 10 . By the fixing protrusion (B) and the first protrusion (a1) or the second protrusion (a2), the syringe 30 or the syringe body 31 may be selectively coupled to the syringe covers 10 and 20.

The fixing protrusion (B) may extend along the circumference of the outer peripheral surface of the needle unit (32). Specifically, the fixing projection (B) is extended along the outer peripheral surface of the needle unit (32), both ends of the fixing projection (B) may be in a ring shape meeting each other.

The fixing protrusion (B) may include an elastic material. Due to this elastic material, when an external force of a certain size or more is applied to the fixing projection (B), the shape of the fixing projection (B) may be deformed or contracted, and then when the external force applied to the fixing projection (B) is reduced or removed In this case, the fixing protrusion (B) may be restored to its original shape by an elastic restoring force.

A process in which the syringe 30 is inserted and coupled to the syringe cover 10 according to an embodiment of the present invention may be as follows, and for convenience of explanation, the syringe 30 is a syringe 30 according to an embodiment of the present invention An embodiment to be inserted into the syringe cover 10 will be mainly described.

First, as shown in Figure 7a, the syringe 30 may be disposed in a position adjacent to the syringe cover (10). Specifically, the syringe 30, the needle portion (N) may be placed on a straight line with the central axis (C1) of the cover body (110). In this case, the user may grip the syringe 30 with one hand, and hold the grip portion 130 or the bent portion 131 with the other hand.

As described above, the user may move the needle unit 32 toward the insertion hole 121 along the insertion direction (eg, the X-axis direction) while holding the bent portion 131 . In this case, the bent part 131 is spaced apart from the cover body 110 by the first distance L1a, so that the user's hand may deviate from the insertion path of the needle part N. Thereby, in the process in which the syringe 30 is inserted into the syringe cover 10 , it is possible to prevent the user from being stabbed in the hand by the needle portion N.

As an embodiment, the user holds the end of the bent portion 131 more protruding in the direction opposite to the insertion (-X-axis direction) than the coupling portion 120 , and inserts the syringe 30 into the syringe cover 10 . can be inserted. In this case, the end of the bent portion 131 gripped by the user is disposed closer to the syringe body 31 than the needle portion N of the syringe 30 in the direction opposite to the insertion (-X-axis direction), whereby the above-described bent The user's hand gripping the end of the part 131 may be positioned to be spaced apart from the needle part N. Accordingly, it is possible to prevent the stab wound from occurring by the needle portion (N).

Next, as shown in FIG. 7B , the needle unit 32 may be inserted into the syringe cover 10 . Specifically, as the needle unit 32 is inserted in the insertion direction (X-axis direction), the fixing protrusion B of the needle unit 32 is disposed on the inner circumferential surface of the insertion hole 121 toward the first protrusion (a1). can move At this time, the fixing projection (b) may be pressed by the first protrusion (a1) having a higher rigidity than the fixing projection (b). In this case, the shape of the fixing projection (b) is deformed by the pressing by the first protrusion (a1) and the elasticity of the fixing projection (b), so that the fixing projection (b) moves in the insertion direction (X-axis direction) in the first direction. It can move past the protrusion a1.

After the fixing projection (b) passes through the first protrusion (a1), the shape of the fixing projection (b) may be restored by the elastic restoring force of the fixing projection (b). In this case, the fixing protrusion b may be fixed by the first protrusion a1 in a state in which the rear surface of the fixing protrusion b is in contact with or caught on the front surface of the first protrusion a1 . Thereby, it is possible to prevent the syringe 30 from coming out of the syringe cover 10 in the direction opposite to the insertion (-X-axis direction).

In the case described above, the first protrusion distance r1 of the first protrusion a1 may be shorter than the third protrusion distance r3 of the fixing protrusion B. At this time, the fixing protrusion (b) may be fixed by contacting the end of the first protrusion (a1) (first fixing state). Accordingly, there may be a certain play between the outer surface of the needle unit (32). In this first fixed state, by applying a force in the direction opposite to the insertion (-X-axis direction) by the user to the syringe 30, the syringe 30 can be separated and discharged again from the syringe cover (10). Thereby, the syringe 30 in a state that has not been used can be temporarily stored by combining the syringe cover 10 and the first coupled state. Accordingly, it is possible to prevent the syringe 30 that has not been used from being contaminated by foreign substances.

Next, as shown in FIG. 7c , the syringe 30 may be further inserted into the syringe cover 10 than in the case of the first fixed state. Specifically, as the needle unit 32 is further inserted in the insertion direction (X-axis direction), the fixing protrusion (b) of the needle unit 32 is disposed on the inner circumferential surface of the insertion hole 121, the second protrusion (a2) can move towards At this time, the fixing projection (b) may be pressed by the second protrusion (a2) having a higher rigidity than the fixing projection (b). In this case, the shape of the fixing projection (b) is deformed by the pressure by the second protrusion (a2) and the elasticity of the fixing projection (b), so that the fixing projection (b) is inserted in the insertion direction (X-axis direction) in the second direction. It can move past the protrusion a2.

After the fixing projection (b) passes through the second protrusion (a2), the shape of the fixing projection (b) may be restored by the elastic restoring force of the fixing projection (b). At this time, by abutting the flat rear surface of the fixing protrusion (b) with the flat front surface of the second protrusion (a2), the fixing projection (b) may be fixed. Thereby, it is possible to prevent the syringe 30 from coming out of the syringe cover 10 in the direction opposite to the insertion (-X-axis direction).

In the case described above, the second protrusion distance r2 of the second protrusion a2 may be the same as or similar to the third protrusion distance r3 of the fixing protrusion b, and accordingly, the second protrusion a2 There may be no play between and the outer surface of the needle unit 32 . At this time, by hooking the rear surface of the fixing protrusion (b) to the front surface of the second protrusion (a2), the syringe 30 may be fixed (second fixing state). In this second fixed state, even if the user applies a force to the syringe 30 in the opposite direction (-X-axis direction), the needle unit ( 32) The syringe 30 may not be separated from the syringe cover 10 again and discharged. Thereby, the used syringe 30 can be stored or processed by combining the syringe cover 10 and the second fixed state.

As described above, in the second fixed state, since the syringe 30 is not separated from the syringe cover 10 again, it is possible to prevent being stabbed by the needle portion N of the syringe 30 that has been used, Accordingly, it is possible to prevent the occurrence of secondary infection by the already used syringe 30 .

The user may select and couple the syringe 30 and the coupling state of the syringe cover 10 to any one of the first fixed state and the second fixed state, as described above. Thereby, depending on whether the use of the syringe 30 is completed, the degree of capping of the syringe 30 by the syringe cover 10 can be adjusted.

As described above, the syringe covers 10 and 20 and the syringe set 1 according to the embodiments of the present invention, the syringe 30 by the bent portion 131 more protruding than the coupling portion 120, It is possible to prevent cuts from occurring during the capping process. In addition, by the two-stage coupling by the protrusions having different protrusion distances, the degree of capping of the syringe 30 can be adjusted depending on whether the syringe 30 is used or not.

In the above, the embodiment shown in the drawings has been described with reference to, but this is merely exemplary, and those of ordinary skill in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
