[0002] Skin disinfection is an essential step before invasive operations such as surgery. Effective skin disinfection can keep the operation site sterile and reduce the incidence of perioperative SSI (surgical wound infection).

[0003] At present, the commonly used disinfection method is that the hand-washing nurse uses disinfection forceps to clamp a certain amount of gauze or cotton balls and put them into the disinfection bowl. Then the circulating nurse pours disinfectant into the disinfection bowl, soaks it and then hands it over to the doctor for disinfection. As a result, one disinfection work requires the cooperation of three people, and the process is cumbersome, which will reduce the processing efficiency of medical staff. If the operation is improper, it will contaminate the sterile disinfection equipment. At present, some manufacturers have tried to produce medical equipment that can be disinfected by only one person. However, due to design or cost issues, the disinfectant often leaks from the equipment.

[0004] Therefore, there is an urgent need for a technology that solves at least one of the above problems. Utility Model Content

[0038] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0039] As described in the background technology, the currently commonly used disinfection method requires the cooperation of multiple people, is cumbersome, inefficient, and easily contaminates sterile instruments; and some manufacturers produce single-person disinfection instruments, which often leak disinfectant from the instruments due to design or cost issues.

[0040] Therefore, the utility model creatively proposes a surgical disinfection brush, which includes a brush body and a liquid storage container. The brush body includes a head and a connecting part, and a first cavity is provided in the head, a second cavity is provided in the connecting part, a third cavity is provided in the liquid storage container, and a liquid blocking ring is provided on the outer peripheral side of the liquid storage container. When preparing for disinfection, the medical staff inserts the matching part of the liquid storage container into the second cavity through the connecting hole. When the matching part and the second cavity are assembled, the liquid outlet is connected with the flow hole, and the disinfectant flows out from the third cavity and flows into the first cavity through the flow hole. The first cavity can extend the flow path of the disinfectant so that the disinfectant flows to the brush head at an appropriate speed. After the brush head absorbs the disinfectant, the medical staff can use the brush head to apply disinfection; at the same time, the liquid blocking ring cooperates with the inner circumference of the second cavity to prevent the disinfectant from leaking through the gap between the second cavity and the liquid storage container.

[0041] The present invention will be described in detail below through specific embodiments.

[0042] This embodiment provides a surgical disinfection brush, referring to Figures 1 to 3 As shown, the surgical disinfection brush includes a brush body 1 and a liquid storage container 2, and the brush body 1 and the liquid storage container 2 are formed separately, and are independently separated and aseptically packaged during packaging to avoid mutual contamination between the two, thereby ensuring the reliability of disinfection.

[0043] Reference Figures 2 to 4 As shown, the brush body 1 comprises a head 11 and a connecting portion 12, wherein a first cavity 112 with an opening 111 at one end is provided in the head 11, the head 11 comprises a brush head 113 made of a soft adsorbent material, the brush head 113 closes the opening 111, the connecting portion 12 comprises a second cavity 121, the second cavity 121 comprises a flow hole 122 communicating with the first cavity 112, and a connecting hole 123 communicating with the outside;

[0044] The liquid storage container 2 has a third cavity 22 with a liquid outlet 21 at one end, a hand-holding portion 24 and a mating portion 25 assembled and connected to the second cavity 121 are provided on the side of the liquid storage container 2, wherein the liquid storage container 2 is plugged into and matched with the connecting hole 123 so that the liquid outlet 21 is connected to the circulation hole 122, and a liquid-blocking ring 4 mating with the inner circumferential wall of the second cavity 121 is provided on the outer peripheral side of the liquid storage container 2.

[0045] In an alternative example, the liquid-blocking ring 4 includes a sealing ring that is interference-fitted with the second cavity 121 ; in this embodiment, the liquid-blocking ring 4 is disposed on the outer peripheral side of the third cavity 22 and is integrally formed with the third cavity 22 .

[0046] In another alternative example, the liquid-blocking ring 4 is an adsorption ring made of a material with adsorption properties, such as sponge.

[0047] Specifically, when preparing for disinfection, the medical staff inserts the matching part 25 of the liquid storage container 2 into the second cavity 121 through the connecting hole 123. In the process of moving the liquid storage container 2 in the second cavity 121, the liquid outlet 21 and the circulation hole 122 begin to be gradually connected, and the disinfectant in the third cavity 22 will flow out through the liquid outlet 21, and flow into the first cavity 112 through the circulation hole 122, and then flow into the soft adsorption material of the brush head 113, so as to be used by the medical staff for disinfection, thereby realizing that one person can complete the surgical disinfection and improving the disinfection processing efficiency; and when the disinfectant flows into the second cavity 121, the liquid blocking ring 4 is circumferentially abutted against the inner side of the second cavity 121 to prevent the disinfectant from leaking through the gap between the second cavity 121 and the liquid storage container 2.

[0048] Among them, through the setting of the first cavity 122, the path of the disinfectant to flow to the brush head 113 is extended, so that the disinfectant flows to the brush head 113 at an appropriate speed, avoiding the disinfectant from directly impacting the end face of the brush head 113, and allowing the brush head 113 to absorb an appropriate amount of disinfectant.

[0049] Furthermore, a guide groove is provided on the inner circumference of the first cavity 122 to guide the disinfectant to the brush head 113; specifically, the guide groove is in an elongated strip shape, and its length direction is consistent with the length direction of the first cavity 122. Preferably, a plurality of guide grooves are evenly provided on the inner circumference of the first cavity 122 along the circumferential direction, so that the disinfectant can flow evenly to the brush head 113 to ensure the disinfection effect.

[0050] In a replaceable example, a membrane rupture portion 3 is further provided in the second cavity 121, and a film 23 is connected to the liquid outlet 21 to seal the liquid outlet 21, wherein when the matching portion 25 and the second cavity 121 are assembled, the membrane rupture portion 3 pierces the film 23, thereby connecting the third cavity 22 and the first cavity 112, and the liquid-blocking ring 4 is circumferentially abutted against the inner side of the second cavity 121.

[0051] In another alternative embodiment, a film 23 is connected to the liquid outlet 21, and medical personnel can remove the film by manually tearing it off.

[0052] When using the disinfection brush, first disassemble the corresponding packaging, and then complete the combination of the brush body 1 and the liquid storage container 2.

[0053] Reference Figure 2 As shown, in order to ensure the disinfection effect and range, the end of the head 11 away from the connecting part 12 is square, and the soft adsorbent material is evenly distributed on the end surface of the head 11. In this embodiment, the soft adsorbent material is a medical grade cotton material, and is bonded to the end surface of the brush head 113 by hot melt adhesive. It can be understood that in other examples, the end surface of the head 11 can also be a circular, elliptical or polygonal structure; at the same time, the soft adsorbent material can also be replaced by other materials that can meet medical disinfection standards and can be used to release disinfectant after adsorption, such as medical sponge materials.

[0054] In this embodiment, the film 23 is made of aluminum foil. It is understandable that the film 23 can also be made of other materials that meet medical disinfection standards and can seal medical disinfectants, such as tin foil.

[0055] It should be noted that, in this embodiment, the disinfectant generally refers to iodine or medical alcohol.

[0056] For ease of use and aesthetics, refer to Figures 2 to 4 As shown, the brush body 1 and the liquid storage container 2 are cylindrical as a whole. Correspondingly, the first cavity 112, the second cavity 121 and the third cavity 22 are all cylindrical.

[0057] Furthermore, in order to improve the sealing performance of the brush body 1 and prevent leakage of the disinfectant, the head 11 and the connecting portion 12 are integrally formed; correspondingly, the first cavity 112 and the second cavity 121 are integrally formed.

[0058] Among them, the circulation hole 122 is located at the center of the second cavity 121, and the axis of the circulation hole 122 coincides with the central axis of the second cavity 121, so that the disinfectant flows evenly to the brush head 113; in order to prevent the instantaneous flow of the disinfectant from being too large and soaking the brush head 113, the ratio of the cross-sectional area of ​​the circulation hole 122 to the cross-sectional area of ​​the first cavity 112 is less than 1 / 2.

[0059] In this embodiment, to ensure smooth flow of the disinfectant, after the liquid storage container 2 and the brush body 1 are assembled, the axis of the liquid outlet 21 coincides with the axis of the flow hole 122, and the ratio of the cross section of the liquid outlet 21 to the cross section of the flow hole 122 is greater than 2.

[0060] Preferably, refer to Figure 1 and Figure 2 As shown, the first cavity 112 and the second cavity 121 are arranged in a linear direction and are in a stepped shaft shape. While facilitating the installation of the liquid storage container 2, the flow rate of the disinfectant after entering the first cavity 112 can be controlled to a certain extent to avoid excessive disinfectant in the first cavity 112.

[0061] Furthermore, a chamfer 124 is provided at the connection between the second cavity 121 and the first cavity 112. Figure 2 As shown, the chamfer 124 is arranged at the end of the second cavity 121 close to the first cavity 112; because the surgical disinfection brush takes the ground as the reference plane when in use, the brush head 113 is generally closer to the ground than the brush body 1, when the membrane piercing portion 3 pierces the film 23, a small portion of disinfectant may flow into the second cavity 121. At this time, the inclined surface formed by the chamfer 124 will guide this portion of disinfectant to flow to the flow hole 122, and then enter into the first cavity 112, so that the disinfectant can fully enter the first cavity 112.

[0062] In some examples, reference Figure 2 As shown, a guide surface 1121 is provided on the inner side of one end of the first cavity 112 close to the second cavity 121. When the disinfectant flows into the first cavity 112, the disinfectant flows along the guide surface 1121 toward the inner wall of the first cavity 112, so that the disinfectant can flow toward the brush head 113 more evenly, so that the soft adsorption material of the brush head 113 can evenly absorb the disinfectant, thereby ensuring the disinfection effect.

[0063] The vertical section of the guide surface 1121 is in a step shape, so that when the head 11 of the brush body 1 faces upward, the guide surface 1121 can prevent the disinfectant from flowing back.

[0064] Further, in some examples, reference Figure 2 As shown, at least one shielding tooth 1122 is provided in the first cavity 112. The shielding tooth 1122 is formed by bending a thin plate and protrudes toward the inner side of the first cavity 112; so that when medical staff use the disinfection brush, the shielding tooth 1122 can play a partial diversion role and shorten the time for the disinfectant to flow to the brush head 113.

[0065] It can be understood that there can be two or even more blocking teeth 1122 , and in order to evenly guide the disinfectant, the multiple blocking teeth 1122 are symmetrically distributed about the center of the flow hole 122 .

[0066] Reference Figure 2 As shown, the membrane-breaking portion 3 includes at least one membrane-breaking tooth 31, and the membrane-breaking tooth 31 has a sharp portion facing the connecting hole 123. In this embodiment, the membrane-breaking tooth 31 is formed by bending a triangular thin plate, and its bending surface protrudes toward the inner side of the first cavity 112, so that after puncturing the film 23, the disinfectant can be directed to the flow hole 122, so that the disinfectant enters the first cavity 112.

[0067] In some examples, the liquid storage container 2 is made of PP material, which is relatively soft.

[0068] Reference Figure 3 and Figure 4 As shown, in order to enhance the structural strength of the liquid storage container 2, a reinforcing structure 5 is provided on the outer circumference of the liquid storage container 2, which effectively avoids the risk of deformation of the liquid storage container 2 (especially the third cavity 22) due to the negative pressure generated inside the liquid storage container 2 when the liquid storage container 2 (especially the third cavity 22) is sterilized with a specific gas. At the same time, it can also avoid deformation during the assembly process, thereby avoiding squeezing of the disinfectant, ensuring the fit between the third cavity 22 and the second cavity 121, and avoiding a large gap between the third cavity 22 and the second cavity 121, which causes the liquid blocking ring 4 to be unable to function and cause leakage of the disinfectant.

[0069] In this embodiment, the specific gas is ethylene oxide; of course, other gases with similar sterilization effects may be used for sterilization, such as propylene oxide and beta-propiolactone.

[0070] It is understandable that the reinforcement structure 5 can be set to two or more, and can be selected according to the material used by the liquid storage container and the requirements of the structural strength. In some examples, the reinforcement structure 5 can be a reinforcement ring arranged around the circumference of the liquid storage container 2.

[0071] Furthermore, when the mating portion 25 is assembled with the second cavity 121, part of the liquid storage container 2 extends out of the connecting hole 123, so that the second cavity 121 can protect the liquid storage container 2 (especially the third cavity 22) to avoid external impact or squeezing. At the same time, the part of the liquid storage container 2 extending out of the connecting hole 123 can be used as a hand-held portion 24 for medical staff to hold.

[0072] In this embodiment, the handle portion 24 includes at least two anti-slip grooves 241 .

[0073] In this embodiment, the hand-held portion 24 is an integrally formed structure of the liquid storage container 2, which is convenient for medical personnel to directly grasp and reduce assembly time. Of course, the hand-held portion 24 can also be designed and processed separately from the liquid storage container 2 according to actual use needs.

[0074] It should be specially explained that, in the present embodiment, the reinforcing structure 5 is integrally provided with the hand-held portion 24 , that is, the reinforcing structure 5 can be used as the hand-held portion 24 while improving the structural strength of the liquid storage container 2 .

[0075] In some examples, reference Figure 2 As shown, in order to improve the convenience of using the disinfection brush, the end surface of the brush head 113 away from the second cavity 121 and the plane where the axis of the first cavity 112 is located form an angle of 20° to 60°, which conforms to the principles of ergonomics.

[0076] There are many ways of assembling and connecting the matching portion 25 of the liquid storage container 2 and the second cavity 121, including threaded connection, plug-in connection, snap-on connection, etc. Figure 3 and Figure 4 As shown, in this embodiment, the matching portion 25 is an external thread, and correspondingly, an internal thread is provided in the second cavity 121 near the membrane-breaking portion 3, so that when the matching portion 25 is gradually screwed into the second cavity 121, the membrane-breaking portion 3 gradually pierces the film 23.

[0077] In this embodiment, the liquid storage container 2 of the surgical disinfection brush can be made in different sizes to adapt to brush bodies 1 of different sizes. When in use, the liquid storage container 2 of corresponding capacity can be selected according to the area of ​​skin to be disinfected and the brush body 1.
