An open distal end of the inner tube is connected to an inner tube cap, and the inner tube and the inner tube cap form a closed chamber for containing disinfectant fluids. The inside of the housing is provided with a punching part, such that when the inner tube advances distally relative to the housing, the punching part will abut and break the inner tube cap.

Description

SKIN DISINFECTANT APPLICATOR

TECHNICAL FIELD

[0001] The disclosure relates to a disinfectant applicator, in particular to a skin disinfectant applicator.

BACKGROUND

[0002] In clinical medicine, doctors need to sterilize the skin with disinfectant fluid before a surgery. The conventional disinfection method is to hold gauze with forceps, and then dip it into disinfectant fluids, such as iodine, medical alcohol, or the like.

SUMMARY

[0003] In one example, the disclosure is directed to a skin disinfectant applicator comprising a housing and an inner tube mating with the housing, the distal end of the housing being provided with a liquid outlet and a wipe end, characterized in that, both the inner tube and the housing are plastic materials, the open distal end of the inner tube being connected with an inner tube cap, the inner tube and the inner tube cap forming a closed chamber for containing disinfectant fluids, and the inside of the housing being provided with a punching part, when the inner tube distally advances relative to the housing, the punching part will abut and break the inner tube cap.

[0004] To prevent the side leakage of the disinfectant fluid, and improve the sealing performance, preferably, the inner tube cap may be fixedly connected (e.g., by welding) to the inner tube.

[0005] To reduce the breaking strength of the inner tube cap, and make the broken of the inner tube cap easier, on the inner tube cap a breaking face may be provided, and the punching part is provided with a convex cone mating with the shape of the breaking face. The shape of the breaking face may be a crossing recessed or triangular or quincunx-shaped or star-shaped structure, accordingly, the shape of the punching part may also be various convex cones mating with the shape of the breaking face. [0006] The details of one or more examples are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

[0013] The skin disinfectant applicator of the present disclosure may be a disposable disinfection product. In one example, as shown in FIGS. 1-3, the disinfectant applicator comprises a housing 1, a housing cap 2, an inner tube 3, an inner tube cap 4, and a sponge block 5. Preferably, both the housing 1 and the inner tube 3 are plastic materials so as to facilitate the transportation, storage, and use.

[0014] The distal end of the housing 1 is provided with a liquid outlet 11, and forms a wipe end 12, on which the sponge block 5 is mounted. The inner tube 3 is inserted into the housing 1, and can axially move relative to the housing 1. The open distal end of the inner tube 3 is fixedly connected (e.g. by welding) with the inner tube cap 4, so that the inner tube 3 and the inner tube cap 4 form a closed chamber containing disinfectant fluids (such as iodine, alcohol, etc.).

[0015] To reduce the breaking strength, and facilitate the breaking, on the inner tube cap 4 the crossing recessed breaking face 41 (the structure thereof may also be star- shaped, quincunx-shaped, triangle, and other shapes) is provided, and accordingly, inside the housing 1 the punching part 13 which abuts and breaks the inner tube cap 4 is provided, and the punching part 13 of the housing 1 is in the form of a crossing- shaped convex cone corresponding to the crossing recessed breaking face 41 on the inner tube cap 4 (the convex cone may also be other shapes mating with the shape of the breaking face) (see FIG 3).

[0016] To ensure the axial positioning of the inner tube 3 relative to the housing 1, and prevent improper operations, at the proximal end of the housing 1 there is provided with the housing cap 2, the top of which forms a tile-shaped depression 21 comprising the opposite side surfaces 210 and 211, and the bottom surface, where the depression 21 in the portion of the bottom surface closely adjacent to the side surface 210 is provided with a hole 212. The proximal end 31 of the inner tube 3 is formed with a stopper handle 311 projecting outward from the outer surface of the inner tube, where the stopper handle 311 is seated on the bottom surface of the depression 21, and the shape of the stopper handle 311 is mating with the shape of the hole 212. In the abutting position of the stopper handle (see FIG. 1), the stopper handle 311, adjacent to the side surface 211, abuts the bottom surface, thereby achieving a rotation limit to make the inner tube 3 unable to move axially; and in the crossed position of the stopper handle, the stopper handle 311, adjacent to the side surface 210, passes through the hole 212, so that the inner tube 3 can distally move in the axial direction relative to the housing 1. To facilitate the force application, the outside wall of the housing 1 is further provided with a pair of side flips 14 which are oppositely arranged to be gripped by a user's fingers.

[0017] In use, the stopper handle 311 is firstly rotated from the abutting position to the hole 212. Then, the disinfectant applicator is held by hand, the thumb pressing the proximal end 31 of the inner tube 3, and the index and middle fingers holding the pair of the side flips 14 of the housing 1. Applying a smaller thrust force, the inner tube 3 will distally advance in the axial direction relative to the housing 1, and the crossing recessed breaking face 41 of the inner tube cap 4 will abut the crossing convex cone in the housing 1 until broken. The disinfectant fluid flows from the inner tube 3 through the wipe end of the housing 1 to the sponge block 5, to provide the pre-surgery skin disinfection by the health care personnel. [0018] In this example, both the inner tube 3 and the housing 1 are plastic materials to avoid broken during the transportation and the storage; and also, the housing cap 2 on one hand may prevent the inner tube 3 from falling out of the housing, and on the other hand may ensure that the disinfectant applicator, when not in use, can be function of a good rotation limit, and prevent improper use, so as to better meet the need of the prior medical disinfection.

[0019] In another example, as shown in FIGS. 4-6, the disinfectant applicator comprises a housing , an inner tube 3', an inner tube cap 4', and a sponge block 5'. All of the inner tube 3', the inner tube cap 4', and the housing may be plastic materials so as to facilitate the transportation, storage, and use.

[0020] The distal end of the housing 1 ' is provided with a liquid outlet 11 ' , and forms a wipe end 12', on which the sponge block 5' is mounted. The inner tube 3' comprises a proximal grip part 3 and a distal connection part 32' . On the connection part 32' an outer thread is provided, and inside the housing a corresponding thread is provided to threadedly engage the outer thread of the connection part 32'. The distal end of the connection part 32' of the inner tube 3' is fixedly connected (e.g., by welding) with the inner tube cap 4', so that the inner tube 3' and the inner tube cap 4' form a closed chamber containing the disinfectant fluid (such as iodine, alcohol, etc.).

[0021] To reduce the breaking strength, and facilitate the breaking, on the inner tube cap 4' there is provided with the crossing recessed breaking face 41 ' (the structure thereof may also be star-shaped, quincunx- shaped, triangle, and other shapes), and accordingly, inside the housing there is provided with the punching part 13' which abuts and breaks the inner tube cap 4', and the punching part 13' of the housing is in the form of a crossing-shaped convex cone corresponding to the crossing recessed breaking face on the inner tube cap 4' (the convex cone may also be other shapes mating with the shape of the breaking face).

[0022] The grip part 3 of the inner tube 3' is held by hand, and the inner tube 3' is circumferentially rotated one cycle, so that the inner tube 3' distally advances and the crossing recessed breaking face on the inner tube cap 4' abuts the crossing- shaped convex cone in the housing until broken. The disinfectant fluid flows through the wipe end of the housing to the sponge block 5', then the pre- surgery skin disinfection may be performed.
