Description

Technology Field

[0001] The present invention relates to a wound dressing applicator, and more specifically, to a wound dressing applicator that allows a user to adjust the dosage of a liquid medicine. Background Technology

[0002] A wound is a physical injury caused by external force in which the skin or other tissue is severed or a defect occurs in a part of the tissue. It is a condition in which the continuity of tissue is destroyed by external pressure and is classified into chronic wounds, such as diabetic ulcers, and acute wounds, such as burns and lacerations.

[0003] Wound dressings are medical devices designed for purposes such as preventing contamination of the wound site, protecting the skin, absorbing exudate, and preventing bleeding or fluid loss. They are used to promote wound healing and protect the wound surface in areas of skin defects. Unlike dry dressings, which typically use gauze or bandages to treat wounds, these are moist dressings. Because they offer higher regenerative effects and can prevent scarring compared to traditional dressings, demand is expanding globally.

[0004] Meanwhile, these wound dressings can be classified into sheet, foam, and liquid types.

[0005] FIG. 10 illustrates an example of a conventional liquid wound dressing applicator (100), where FIG. 10 (a) shows a state with a stopper (103) attached, and FIG. 10 (b) shows a cross-sectional view when the stopper (103) is removed.

[0006] The existing wound dressing applicator (100) includes a body portion (101) and a head portion (102) having a wound dressing application portion (1021).

[0007] The body part (101) has a space (S) in which a liquid medicine is located inside, a protrusion (1011) is provided around the perimeter, and a seal (1012) is disposed at the end.

[0008] The head portion (102) has two grooves (1021, 1022) spaced apart from each other. It also has a seal breaking portion (1023) capable of breaking, i.e., tearing, the seal (1012).

[0009] In the state before use (Fig. 10 (a)), the seal breakage part (1023) is positioned at a distance from the seal (1012) due to the stopper (103).

[0010] To apply the liquid medicine to the patient's skin, the stopper (103) is removed and the head portion (102) is slid relative to the body portion (101), causing the projection (1011) to be fitted into the groove (1022). At this time, the seal break portion (1023) tears the seal (1012), causing the liquid medicine located in the space (S) to flow out toward the application portion (1021), thereby allowing the liquid medicine to be applied to the patient's skin (see FIG. 10 (b)).

[0011] However, in conventional wound dressing applicators, once the seal (1012) that prevents the liquid from flowing out of the space (S) is torn, the liquid continues to flow out and cannot be stopped midway. As a result, there was a problem in that the user had to use it without stopping until the liquid came out, or if the liquid ran out in the middle of the procedure, use an additional applicator.

Specific details for implementing the invention

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can implement the invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0029] FIG. 1 shows a schematic diagram of a liquid wound dressing applicator according to one embodiment of the present invention.

[0030] The wound dressing applicator of the present invention comprises a body part (1), a connecting part (2), and a head part (3) as main components.

[0031] As shown in FIG. 2, the body part (1) comprises a body part case (11), a separator plate (14) that divides the internal space of the body part case (11) into a first space (S1) and a second space (S2), a first seal (15) that seals the entrance of the first space (S1), and a second seal (16) that seals the entrance of the second space (S2).

[0032] The body part case (11) includes a body part case large diameter portion (111), a body part case small diameter portion (112) that is stepped from the body part case large diameter portion (111) and has a relatively smaller outer diameter, and a projection (113) located on the surface of the body part case small diameter portion (112). The body part case large diameter portion (111) may be formed so that its outer diameter gradually increases toward the body part case small diameter portion (112).

[0033] As shown in FIGS. 1 and 3, the connecting part (2) is connected to the body part (1) and is provided with a first seal breaking part (22) capable of breaking the first seal (15) and a second seal breaking part (23) capable of breaking the second seal (16). Meanwhile, it is preferable that the first seal breaking part (22) and the second seal breaking part (23) have pointed tips so that they can easily tear the first seal (15) and the second seal (16) when in contact with them (see FIG. 3 (c)). Also, the first seal breaking part (22) and the second seal breaking part (23) may be formed with different heights; for example, the first seal breaking part (22) may be formed to be higher (in the transverse direction of FIG. 3 (c)) than the second seal breaking part (23).

[0034] Additionally, the connecting part (2) includes a connecting part large diameter part (21) into which the small diameter part (112) of the body part case (11) is inserted, and a connecting part small diameter part (24) which is connected to the connecting part large diameter part (21) with a step difference and has a relatively small outer diameter.

[0035] The connecting large diameter portion (21) is spaced apart in the longitudinal direction (transverse direction based on (c) of FIG. 3) and includes three grooves (211, 212, 213) into which the projection (113) of the body portion case (11) can be selectively inserted.

[0036] The connecting portion small diameter portion (24) further includes an annular protrusion (241) positioned at a predetermined distance from the connecting portion large diameter portion (21), as shown in FIGS. 3 and 9.

[0037] As shown in FIGS. 1 and 4, the head portion (3) is connected to the connecting portion (2) and has a wound dressing application portion (31) at its end.

[0038] Additionally, referring to FIG. 9, the head portion (3) includes a head portion case (33) into which a connecting portion small diameter portion (24) is inserted, and one or more elastic tilting portions (32) mounted on the outer wall of the head portion case (33). In this embodiment, two elastic tilting portions (32) located opposite each other are illustrated as an example.

[0039] The elastic tilting part (32) includes a pressure part (323) located at one end of the elastic tilting part (32), a catch (322) located at the other end of the elastic tilting part (32) that can be caught on an annular protrusion (241), and an elastic fixing part (321) fixed to the head part case (33) and always exerts a restoring force in the direction in which the catch (322) is caught on the annular protrusion (241).

[0040] Meanwhile, as shown in FIG. 1, a first stopper (41) and a second stopper (42) may be disposed in the small diameter portion (112) of the body part case (11).

[0041] With the first stopper (41) and the second stopper (42) positioned, the projection (113) is coupled to the first groove (211) located closest to the tip of the connecting part (2) among the three grooves (211, 212, 213). For reference, the term "tip" of the component refers to the part located furthest to the right in FIG. 1, and the term "end" refers to the part located furthest to the left in FIG. 1.

[0042] As shown in FIG. 5, in the small diameter portion (112) of the body part case (11), either of the first and second stoppers (41, 42) may be removed, for example, and only the second stopper (42) may be placed, and as shown in FIG. 6 (a), in this state, the connecting portion (2) is moved relatively toward the body part (1) to connect the projection (113) of the body part case (11) to the second groove (212) located in the middle of the three grooves (211, 212, 213).

[0043] As illustrated in FIG. 6 (c) and (d), at this time, the first seal break portion (22) tears and breaks the first seal (15), and the second seal break portion (23) is positioned at a distance from the second seal (16). Therefore, the liquid medicine located in space (S1) flows toward the head portion (3). And the liquid medicine located in space (S2) cannot flow out to the outside because the second seal (16) is sealed.

[0044] The user rubs the application portion (31) of the head portion (3) on the wound area where wound dressing needs to be applied. Then, if it is determined that the liquid medicine no longer flows out from the space (S1) or that the application portion (31) needs to be replaced, the used head portion (3) can be separated from the connecting portion (2), and a new head portion (3) can be attached to the connecting portion (2) to replace it.

[0045] As illustrated in FIG. 9(b), when replacing the head part (3), pressing the pressure part (323) of the elastic tilting part causes the two elastic tilting parts (32) to spread apart from each other, and at this time, the catch (322) that was caught on the annular protrusion (241) separates from the annular protrusion (241). In this state, the used head part (3) can be separated from the connecting part (2). Then, with the new head part (3) inserted into the connecting part (2), if the external force applied to the pressure part (323) is removed, the elastic tilting part (32) is closed again by the elastic fixing part (321), and at this time, the catch (322) catches on the annular protrusion (241), preventing the head part (3) from detaching from the connecting part (2) (see FIG. 9(a)).

[0046] Next, as shown in FIGS. 7 and 8, the second stopper (42) is removed and the connecting part (2) is moved relative to the body part (1) so that the end of the large diameter part (111) and the tip of the connecting part (2) come into contact. At this time, the projection (113) of the body part case (11) is coupled to the third groove (213) located closest to the end among the three grooves (211, 212, 213) of the connecting part (2). Then, the second seal breaking part (23) tears and breaks the second seal (16).

[0047] Therefore, the liquid medicine located in the space (S2) flows toward the head portion (3). The user rubs the application portion (31) of the head portion (3) on the wound area where the wound dressing needs to be applied.

[0048] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
