Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a splash-proof face shield. Background Technology

[0002] Currently, medical staff in hospitals are required to use protective face shields when performing invasive procedures on patients. These face shields are mostly disposable medical devices made of transparent plastic, with an elastic band attached to the top. When using them, the elastic band is placed over the back of the medical staff's head, and the face shield is positioned in front of the staff. This way, during invasive procedures, the face shield can, to some extent, prevent the patient's blood, bodily fluids, and secretions from splashing onto the operator's face and eyes.

[0003] However, existing protective face shields cover the face, leaving a gap between the shield and the head, and do not extend downwards to the neck for protection; or even if the shield extends downwards to the neck, the gap between the shield and the neck is too large. This results in insufficient protection for the neck, allowing medical personnel to easily splash blood, bodily fluids, and secretions onto the neck when performing medical procedures above the patient. Furthermore, these fluids may even spray upwards through the gap between the face and the shield, reaching the face and eyes. Therefore, the protective capabilities of existing face shields still need improvement. Utility Model Content

[0004] The present invention aims to provide a splash-proof face shield to protect the necks of medical personnel and improve the protective capability of the face shield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a splash-proof face shield, including a face shield, a neck shield connected to the bottom of the face shield, and a fitting support part fixedly provided on the top of the face shield for fitting against the forehead, and an air vent provided on the fitting support part.

[0006] The principle and advantages of this solution are as follows: The face shield is worn in front of the face, and the fitting support part is used to fit the forehead. The fitting support part separates the face shield from the face and supports the face shield. At the same time, the fitting support part makes a gap between the face shield and the face shield, avoiding the face shield from being too close to the face shield.

[0007] The face shield in this design provides protection for the face and eyes. A neck shield is integrated at the bottom of the face shield, positioned in front of the neck and fitting snugly to protect it. This design effectively protects the neck, preventing blood, bodily fluids, and secretions from splashing onto the operator's neck during invasive procedures. Because the neck shield fits snugly against the neck and connects to the bottom of the face shield, it blocks the gap between the bottom of the face shield and the neck. This prevents blood, bodily fluids, and secretions from entering the gap between the face and neck from the bottom of the face shield, significantly enhancing protection for the face, eyes, and neck.

[0008] This design incorporates an air vent on the support structure. This vent allows for air exchange at the top of the mask, facilitating ventilation between the inside and outside of the mask. This prevents fogging around the eyes from obstructing vision. The air vent's location at the top of the mask, compared to other parts, is closer to the eyes, effectively preventing fogging around the eyes.

[0009] Preferably, as an improvement, the fitting support includes multiple support blocks, which are arranged laterally along the top of the screen, and gaps are formed between adjacent support blocks to form an air outlet.

[0010] Preferably, as an improvement, the fitting support part includes a support strip, which is horizontally fixed to the inner side of the top of the face screen, and the air outlet part consists of multiple air outlets located on the support strip, with the air outlets arranged vertically.

[0011] Therefore, the bonding support can be configured in different forms. When configured as a support block, multiple support blocks are required, which are horizontally distributed along the top of the screen, with gaps between adjacent support blocks, allowing for gas exchange between the inside and outside of the screen. When the bonding support is configured as a support strip, the support strip is horizontally fixed to the inner side of the top of the screen, and multiple vent holes are provided on the support strip, allowing for gas exchange between the inside and outside of the screen.

[0012] Preferably, as an improvement, the vent is a square or round hole. Therefore, the shape of the vent can be set to different shapes.

[0013] Preferably, as an improvement, the bonding support further includes a bonding strip, which is fixedly located on the side of the support block away from the front screen, and the bonding strip is flexible.

[0014] Preferably, as an improvement, the bonding support further includes a bonding strip, which is fixedly located on the side of the support strip away from the face screen, and the bonding strip is flexible.

[0015] Therefore, the fitting band is used to fit the forehead. The fitting band is flexible. When the fitting band is applied to the forehead, its softness can reduce the pressure of the fitting support on the forehead. This avoids the discomfort caused by the support block or support band being made of harder materials and directly affecting the head, thus improving the comfort of the fitting support and the forehead.

[0016] Preferably, as an improvement, the support block is made of sponge, rubber, or plastic.

[0017] Preferably, as an improvement, the neck shield is connected to a connecting part, which is connected to the bottom of the face screen. Thus, the connecting part enables the connection between the neck shield and the bottom of the face screen.

[0018] Preferably, as an improvement, the top of the connecting part is provided with a slot, and the bottom of the face shield is inserted into the slot. Thus, by inserting the bottom of the face shield into the slot, the connecting part and the bottom of the face shield are connected. When it is necessary to separate the connecting part from the bottom of the face shield, the bottom of the face shield can be pulled out of the slot by force. Therefore, with this solution, the connection between the neck shield and the bottom of the face shield is convenient, facilitating quick assembly and wearing of the face shield and neck shield.

[0019] Preferably, as an improvement, the inner wall of the slot is provided with a slot, and the bottom side of the screen is provided with a protrusion, which engages in the slot. Thus, when the bottom of the screen is inserted into the slot, and the protrusion engages in the slot, the connection between the connector and the bottom of the screen is more stable.

[0029] Example 1

[0030] The basics are as follows: Figure 1 , Figure 2 and Figure 5 As shown: This embodiment discloses a splash-proof face shield, including a face shield 1, which is made of transparent plastic. The surface of the face shield 1 is curved from left to right. The width of the top 3 of the face shield is smaller than the width of the bottom 2 of the face shield. In this embodiment, the thickness of the face shield 1 is 0.5-1mm. Elastic bands 4 are connected to both ends of the top 3 of the face shield.

[0031] In this embodiment, a neck shield 5 is connected to the bottom 2 of the face shield. The neck shield 5 is made of fabric, such as a medical towel or cloth. The neck shield 5 and the bottom 2 of the face shield are specifically fixed as follows: the top of the neck shield 5 can be glued to the inner side or the outer side of the bottom 2 of the face shield; or, in combination with... Figure 5 As shown, a connecting part is adhered to the inner side of the bottom 2 of the face screen, and the top of the neck shield 5 is adhered to the connecting part. In this embodiment, the connecting part can be a long strip of sponge block with a thickness of 1-2 cm. The top of the neck shield 5 is adhered to the side of the sponge block away from the face screen 2. Of course, in other embodiments, the top of the neck shield 5 and the bottom 2 of the face shield can also be connected by Velcro. For example, a Velcro tab is attached to the inside of the bottom 2 of the face shield, and a Velcro tab is attached to the top of the neck shield 5. By attaching the Velcro tab and the Velcro tab together, the top of the neck shield 5 and the bottom 2 of the face shield can be detachably connected. The top of the neck shield 5 and the bottom 2 of the face shield are easy to connect and separate, and easy to put on and take off. It can be selected whether to connect the top of the neck shield 5 and the bottom 2 of the face shield according to the actual situation. If the medical staff does not perform invasive operations and performs ordinary use, they only need to wear the face shield 1 and do not need to wear the neck shield 5. If the medical staff performs invasive operations, the top of the neck shield 5 and the bottom 2 of the face shield are connected.

[0032] Combination Figure 1 As shown, the neck shield 5 is also connected to the two sides of the neck shield 5 with fixing ropes 16. The number of fixing ropes 16 on each side of the neck shield 5 can be set to one or two.

[0033] A fitting support portion for conforming to the forehead is fixedly provided on the inner side of the top 3 of the face screen, and an air vent is provided on the fitting support portion. Specifically, in this embodiment, combined with Figure 2 As shown, the fitting support part includes multiple support blocks 6, which are arranged laterally along the top 3 of the front screen. There are gaps 7 between adjacent support blocks 6 to form an air vent. The support blocks 6 can be made of rubber, sponge or plastic, and the thickness of the support blocks 6 is 1-2cm.

[0034] Therefore, in this embodiment, the face shield 1 is worn in front of the face, the elastic band 4 is looped around the back of the head to fix the face shield 1 in front of the face, and the neck shield 5 is located on the front of the neck, with the fixing rope 16 wrapped around the back of the neck and tied together, so that the neck shield 5 fits snugly against the neck. After the face shield is worn, the support block 6 fits against the forehead, separating the face shield 1 from the face. The support block 6 supports the face shield 1, and at the same time, the support block 6 creates a gap between the face shield 1 and the face, preventing the face shield 1 from being in close contact with the face.

[0035] In this embodiment, after the face shield is worn, the face shield 1 protects the face and eyes. Simultaneously, a neck shield 5 is located at the bottom 2 of the face shield, covering the front of the neck and fitting snugly against it. This prevents blood, bodily fluids, and secretions from splashing onto the operator's neck during invasive procedures, such as during bronchoscopy, preventing respiratory secretions from splashing upwards onto the operator's neck. Furthermore, because the neck shield 5 fits snugly against the neck, and its top connects to the bottom 2 of the face shield, it blocks the gap between the bottom 2 of the face shield and the neck. Blood, bodily fluids, and secretions cannot enter the gap between the face and the face shield 1 from the bottom, thus achieving protection for the face, eyes, and neck, significantly improving protective capabilities.

[0036] In this embodiment, the gap 7 between two adjacent support blocks 6 allows for gas exchange at the top of the mask, and ventilation is allowed between the inside and outside of the mask through the gap 7 between the two adjacent support blocks 6, thereby preventing fogging around the eyes of the face shield 1 from affecting vision.

[0037] Example 2

[0038] This embodiment provides a different fitting support portion than that in Embodiment 1, combined with... Figure 3As shown, the bonding support in this embodiment includes not only the support block 6 but also a bonding strip 10. The bonding strip 10 is elongated and has a thickness of 0.2-0.5 cm. The bonding strip 10 is attached to the side of the support block 6 away from the front screen 1. The bonding strip 10 in this embodiment is flexible and can be made of rubber or sponge. The thickness of the support block 6 in this embodiment can be set to 0.5-1.5 cm.

[0039] Therefore, when this mask is worn on the head, the fitting band 10 fits snugly against the forehead. Compared to Embodiment 1, where only the support block 6 contacts the forehead, the fitting band 10 has a larger contact area with the forehead, which helps improve the stability of the mask on the head. At the same time, the fitting band 10 is made of a flexible material, making it relatively soft. The support portion does not exert significant pressure on the forehead, thus improving comfort. This allows the support block 6 to be made of a rigid material such as plastic. Furthermore, the gap 7 between adjacent support blocks 6 in this embodiment can still serve as an air vent for ventilation.

[0040] Example 3

[0041] This embodiment provides a fitting support portion with a different structure from Embodiment 1, combined with... Figure 4 As shown, the bonding support in this embodiment includes a support strip 8 and a bonding strip 10. Both the support strip 8 and the bonding strip 10 are elongated strips, bonded together. The support strip 8 is horizontally bonded to the inner side of the top 3 of the faceplate. The air outlet in this embodiment consists of multiple air holes 9 located on the support strip 8. The air holes 9 are all vertically arranged and distributed along the length of the support strip 8. The bonding strip 10 in this embodiment is flexible and can be made of rubber or sponge. The support strip 8 can be made of plastic. The thickness of the support strip 8 can be 0.5-1.5 cm, and the thickness of the bonding strip 10 can be 0.2-0.5 cm. The air holes 9 can be square or round.

[0042] Example 4

[0043] Combination Figure 6 As shown, this embodiment differs from Embodiment 1 in that it provides a different connection method between the neck shield 5 and the bottom of the face screen 2. In this embodiment, a connecting part is also glued and fixedly connected to the top of the neck shield 5. The connecting part in this embodiment is a connecting block 12, which is long and strip-shaped. The connecting block 12 in this embodiment is made of rubber or plastic. A slot 13 is provided on the top of the connecting block 12, and the bottom of the face screen 1 can be inserted into the slot 13. In order to ensure the stability of the bottom of the face screen 2 inserted into the slot 13, the depth of the slot 13 can be set to 0.5-1cm. In this embodiment, the width of the slot 13 is slightly smaller than the thickness of the face screen 1, specifically less than 0.1-0.2mm.

[0044] Thus, the bottom 2 of the front screen is inserted into the slot 13, thereby connecting the connecting part and the front screen 1. Since the width of the slot 13 is slightly smaller than the thickness of the front screen 1, after the bottom 2 of the front screen is inserted into the slot 13, the inner wall of the slot 13 clamps the front screen 1, making it difficult for the connecting part to fall off the bottom 2 of the front screen, thus ensuring the connection stability between the neck shield 5 and the bottom 2 of the front screen. Using the connection method in this embodiment, the connection between the bottom 2 of the front screen and the neck shield 5 is convenient and quick. The front screen 1 and the neck shield 5 can be manufactured separately, and whether or not to connect the front screen 1 and the neck shield 5 can be selected according to the specific usage scenario.

[0045] In this embodiment, the top of the neck shield 5 is relatively loose during actual use, which provides sufficient space for head shaking and avoids the neck shield 5 being too tight, thus affecting head shaking.

[0046] Example 5

[0047] Combination Figure 7 As shown, this embodiment further defines the feature based on embodiment 4. In this embodiment, the inner wall of the slot 13 is provided with a slot, and protrusions 14 are integrally provided on both sides of the bottom of the front screen 2. The protrusions 14 are engaged in the slot. Therefore, when the bottom of the front screen 2 is inserted into the slot 13, and the protrusions 14 are engaged in the slot, the connection between the connecting block 12 and the bottom of the front screen 2 is more stable, and the connecting block 12 and the bottom of the front screen 2 are less likely to separate, ensuring stable operation.

[0048] In order to facilitate the insertion of the front screen 1 into the slot 13, this embodiment provides a chamfer 15 at the top of the slot 13, so as to facilitate the insertion of the bottom 2 of the front screen into the slot 13.

[0049] The anti-splash face shield in the above embodiments has a simple structure, is easy to manufacture, and has a low production cost. It can be used as a disposable medical device, for example, in infectious disease wards.
