Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a surgical mask that can be quickly cleaned. Background Art

[0002] In surgical operations, patients often spurt blood. Even in some joint replacements or osteotomies, not only blood may spurt, but also some bone fragments may spurt out. Bone fragments and blood spurts may stain the face or eyes of medical staff, causing occupational exposure to medical staff and bringing serious psychological and physiological burdens to medical staff. Therefore, when performing related operations, medical staff must wear special surgical masks to perform necessary surgical isolation.

[0003] Existing masks generally include a transparent curved baffle and a headband that can be worn on the head. The transparent curved baffle covers the face of medical staff to block dirt such as bone residue and blood. However, when the curved baffle is splashed by dirt, the dirt easily blocks the doctor's sight, thereby affecting the normal progress of the operation. Chinese patent document CN104223494A discloses a surgical protective mask that can be cleaned on site. It consists of a head cover, a guard plate, and a mask. The top of the head cover is a double-layer structure with an opening at the front of the double-layer structure. The guard plate is a bendable transparent material. The upper end of the guard plate is inserted into the front opening of the head cover. A horizontal sponge strip is installed in the double-layer structure of the head cover. The sponge strip is connected to the lower surface of the upper structure of the double-layer structure. The guard plate is located below the sponge strip. The upper end of the guard plate is connected to a traction belt, and the end of the traction belt is led out from the rear of the double-layer structure. When blood splashes onto the guard plate and affects the line of sight, pull the pull belt backwards, the sponge strip in the headgear can wipe the blood on the guard plate, and the adsorption strip can absorb the flowing blood and water mixture. After wiping, pull the guard plate downward to continue the surgical operation. The above technical solution uses a sponge strip to wipe the guard plate on site. Although it can remove dirt to a certain extent, it still has the following defects: 1) The sponge strip has adsorption properties and limited adsorption capacity. After wiping several times, the sponge strip will be soaked with blood. The sponge strip soaked with blood obviously cannot completely wipe the guard plate clean, so that the guard plate cannot be restored to clarity; 2) The adsorption capacity of the adsorption strip is limited. After multiple adsorptions, the adsorption strip reaches saturation and cannot continue to adsorb blood and water, causing dirt to flow and drip onto the face and body of medical staff. Therefore, when encountering a surgery with a lot of splashes, the above protective mask obviously cannot keep the guard plate clear for a long time. During the operation, replacing the surgical shield or replacing the sponge strip or adsorption strip will obviously cause the operation process to be interrupted or delayed, seriously affecting the progress and quality of the operation.

[0004] Therefore, there is an urgent need for a surgical mask that can protect the face and prevent dirt from blocking the doctor's vision, and can also be continuously and quickly cleaned when facing operations with a lot of spatter. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of the surgical masks in the prior art that, when encountering operations with a lot of spatters, the sponge strips for wiping the shield and the adsorption strips for absorbing blood and water easily reach saturation after multiple adsorptions, and the dirt cannot be wiped and adsorbed continuously, so that the shield cannot be kept clear throughout the entire operation, and the dirt is easily caused to flow and drip onto the faces and bodies of medical staff, causing pollution to the medical staff. The present invention thus provides a surgical mask that can protect the face and prevent dirt from blocking the doctor's vision, and can also be continuously cleaned quickly when facing operations with a lot of spatters.

[0044] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] This embodiment provides a surgical mask that can be quickly cleaned, such as Figure 1-5 As shown, it includes a mask body 1, a fixing belt 2 and a film supply mechanism 3; wherein the mask body 1 is suitable for covering the human face, and a transparent eye mask 11 is arranged corresponding to the position of the human eye; the fixing belt 2 is arranged on the mask body 1, and is used to fix the mask body 1 on the human head; the film supply mechanism 3 is installed on the mask body 1, and is located on one side of the eye mask 11, and a transparent anti-fouling film 31 with a certain length is accommodated inside; the width of the anti-fouling film 31 is greater than or equal to the width of the eye mask 11, and the anti-fouling film 31 can be continuously pulled out from the film supply mechanism 3 and covered on the eye mask 11.

[0046] In the quick-cleanable surgical mask of this embodiment, the length of the anti-fouling film 31 can be determined according to different surgical operations. When it is expected that dirt splashing may occur frequently during the operation, or the amount of splashed dirt is expected to be large, the length of the anti-fouling film 31 can be set to be longer; when it is expected that the probability of dirt splashing during the operation is low, or the amount of splashed dirt is small, the length of the anti-fouling film 31 can be set to be shorter. When the medical staff wear the surgical mask of the present embodiment to perform a surgical operation, the splashed blood, tissue fluid, bone chips, bone slag and other dirt will be blocked by the mask body 1 to prevent the dirt from contacting the face of the medical staff; when the amount of dirt splashed is large and has blocked the medical staff's vision, it is only necessary to pull the anti-fouling film 31 to pull out a new anti-fouling film 31 of a certain length from the film supply mechanism 3 and cover the eye mask 11, and then tear off or cut off the anti-fouling film 31 stained with dirt, so that the dirt attached to the anti-fouling film 31 can be separated from the mask body 1 together with the anti-fouling film 31, so that the medical staff's vision can be restored to a clear state again; in the subsequent operation, if the amount of dirt splashed once again blocks the medical staff's vision, the anti-fouling film 31 can be pulled again, and a new anti-fouling film 31 can be pulled out from the film supply mechanism 3 to cover the eye mask 11, and then the anti-fouling film 31 stained with dirt can be torn off or cut off, so that the medical staff's vision can be restored to a clear state again. That is to say, by timely pulling out a new anti-fouling film 31 from the film supply mechanism to cover the eye mask 11, and tearing off or cutting off the anti-fouling film 31 with dirt attached, the dirt that blocks the medical staff's vision can be quickly removed at one time, thereby ensuring a clear field of vision during surgery. In the surgical mask that can be quickly cleaned in this embodiment, the film supply mechanism 3 includes a reel 32 and an anti-fouling film 31; wherein the reel 32 is rotatably mounted on the outside of the mask body 1 through a connecting structure; the anti-fouling film 31 is wound and stored on the reel 32, and has a free end 311 suitable for being pulled.

[0047] The quickly cleanable surgical mask of this embodiment, further, the connecting structure includes two support seats 12, which are fixedly mounted on the mask body 1 on the left or right side of the eye mask 11 and are opposite to each other up and down; the support seat 12 has a vertically through mounting hole 121, the two mounting holes 121 are opposite to each other up and down, and the side of the mounting hole 121 away from the mask body 1 has an opening 122; a limiting portion 321 is provided at the upper end of the reel 32, and the outer diameter of the limiting portion 321 is larger than the inner diameter of the mounting hole 121; the reel 32 can be detachably installed into the mounting hole 121 through the opening 122, and is limited by the limiting portion 321, and the reel 32 can rotate freely in the two mounting holes 121.

[0048] In this embodiment, the opening 122 may be slightly smaller than the outer diameter of the reel 32, and the reel 32 may be installed into the mounting hole 121 through the opening 122 by pressing with an external force, or may be removed from the mounting hole 121 through the opening 122 by pulling with an external force. When the free end 311 of the anti-fouling film 31 is pulled, the reel 32 may rotate freely in the mounting hole 121 and will not fall out of the mounting hole 121.

[0049] In the quick-cleanable surgical mask of this embodiment, the anti-fouling film 31 includes a plurality of sub-anti-fouling films 312 connected end to end, and adjacent sub-anti-fouling films 312 are connected by an easy-tear structure 313; the length of the sub-anti-fouling film 312 is greater than the length of the eye mask 11.

[0050] The quickly cleanable surgical mask of this embodiment further comprises: the easy-tear structure 313 being an easy-tear line arranged between two adjacent sub-antifouling films 312; the length of the easy-tear line is the same as the width of the sub-antifouling films 312; and the easy-tear line is formed by alternating breakpoints and connection points in sequence.

[0051] In this embodiment, a sub-antifouling film 312 can be covered on the eye mask 11 each time. Since the length of the sub-antifouling film 312 is greater than the length of the eye mask 11, the extra part of the sub-antifouling film 312 is easier to grasp and pull when the sub-antifouling film 312 is pulled. When the sub-antifouling film 312 covering the eye mask 11 is attached with dirt and blocks the vision, only the sub-antifouling film 312 needs to be pulled to pull out a new sub-antifouling film 312 from the film supply mechanism 3 and cover the eye mask 11. Then, the sub-antifouling film 312 with dirt attached can be torn off along the easy-tear line, so that the dirt attached to the sub-antifouling film 312 can be separated from the mask body 1 together with the sub-antifouling film 312, so that the vision of the medical staff can be restored to a clear state again.

[0052] The quickly cleanable surgical mask of the present embodiment further includes two limiting plates 13, which are fixedly arranged on the mask body 1 at the upper and lower sides of the eye mask 11 respectively; the limiting plates 13 are long strips and extend from one side of the eye mask 11 to the other side along the length direction of the eye mask 11; the cross-section of the limiting plates 13 is L-shaped, and the two limiting plates 13 are respectively enclosed with the mask body 1 to form limiting grooves 131 with opposite openings; the anti-fouling film 31 can extend from one side of the eye mask 11 through the limiting groove 131 to the other side, and is limited by the limiting groove 131 to fit the eye mask 11.

[0053] In this embodiment, the upper limiting plate 13 can block the splashed dirt to prevent the dirt from entering between the anti-fouling film 31 and the eye mask 11, and the upper and lower limiting grooves 131 can limit the anti-fouling film 31 located therein so that it always fits with the eye mask 11.

[0054] The quickly cleanable surgical mask of this embodiment further includes a fixing structure 14 , which is arranged on a side of the mask body 1 opposite to the film supply mechanism 3 and is used to fix the free end 311 of the anti-fouling film 31 .

[0055] In this embodiment, after the anti-fouling film 31 is covered on the eye mask 11, the fixing structure 14 can temporarily fix the free end 311 of the anti-fouling film 31; when the anti-fouling film 31 needs to be pulled, the free end 311 of the anti-fouling film 31 can be removed from the fixing structure 14. Specifically, the surface of the fixing structure 14 can be an adhesive surface, so that the free end 311 can be fixed by adhesive; or the fixing structure 14 can be a clip, so that the free end 311 can be clamped and fixed.

[0056] The quick-cleanable surgical mask of this embodiment, the fixing belt 2 includes a first belt 21, a second belt 22 and an adhesive belt 23; one end of the first belt 21 is fixedly connected to one side of the mask body 1; one end of the second belt 22 is fixedly connected to the other side of the mask body 1; the adhesive belt 23 is respectively installed on the other end of the first belt 21 and the other end of the second belt 22, and is used to detachably connect the first belt 21 and the second belt 22.

[0057] The quick-cleanable surgical mask of this embodiment further comprises two sets of fixing belts 2, which are respectively mounted on the upper and lower parts of the mask body 1. In this embodiment, the two sets of fixing belts 2 can be fixed to the upper and lower positions of the head respectively.

[0058] The quickly cleanable surgical mask of this embodiment further includes an upper support pad 15 and a lower support pad 16; wherein the upper support pad 15 is installed at a position corresponding to the forehead on the inner side of the mask body 1, and is in the shape of a long strip extending along the left and right directions of the mask body 1; the lower support pad 16 is installed at a position corresponding to the chin on the inner side of the mask body 1, and is in the shape of a long strip extending along the left and right directions of the mask body 1.

[0059] In this embodiment, the upper support pad 15 and the lower support pad 16 can increase the gap between the face and the mask body 1, which is beneficial to the circulation of air inside the mask body 1, thereby improving the wearing comfort. The upper support pad 15 and the lower support pad 16 can be made of a flexible material, such as a silicone material, or a soft foam material, thereby improving the wearing comfort.

[0060] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of this innovative technical solution.
