Description

Technical Field

[0001] This utility model relates to the field of ventilator mask technology, specifically an adjustable ventilator mask. Background Technology

[0002] A ventilator mask is a medical device used in medical or emergency situations. It is typically made of soft material and covers the mouth and nose to provide oxygen or regulate airflow. A ventilator mask is an important component of a ventilator system, used to connect the ventilator to the patient for artificial or assisted ventilation. Artificial ventilation: In emergency or surgical situations, the ventilator mask connects to the ventilator to provide regulated oxygen or a gas mixture, maintaining the patient's respiratory function. Assisted ventilation: For patients with breathing difficulties or requiring assisted breathing, the ventilator mask can provide additional oxygen or airflow support to help them maintain normal breathing.

[0003] When using some existing ventilator masks, the mask is aligned with the patient's face, and then the symmetrical elastic bands are placed over the upper and lower sides of the patient's head for wearing.

[0004] Existing ventilator masks of this type have the following problems: when using a ventilator mask, if the elastic band is worn on the patient's head for a long time, it will cause marks on the patient's head and make the patient feel uncomfortable. Therefore, we propose an adjustable ventilator mask. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an adjustable ventilator mask. When using the ventilator mask, the tightness of the straps can be quickly adjusted. When the straps are on the patient's head for a long time, they will not cause chafing marks on the patient's head, thus avoiding discomfort to the patient. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable ventilator mask, including a mask, a connecting tube at the air inlet at the front end of the mask, a mounting block at the upper end of the mask, a T-shaped piece rotatably connected inside the mounting block, hooks 1 respectively installed on the left and right sides of the upper end of the T-shaped piece, connecting buckles at the left and right ends of the mask, and hooks 2 respectively installed on the outer ends of the connecting buckles, and also includes an adjustment mechanism;

[0007] Adjustment mechanism: It includes straps, connecting straps and buckles. The right end of hook one on the right side and the right end of hook two on the right side are respectively equipped with straps. The left end of hook one on the left side and the left end of hook two on the left side are respectively equipped with connecting straps. The left end of each connecting strap is equipped with a buckle. The front end of each strap is fitted with a vertically adjacent buckle. When using a ventilator mask, the tightness of the straps can be quickly adjusted. When the straps are worn on the patient's head for a long time, they will not cause marks on the patient's head, thus avoiding discomfort.

[0008] Furthermore, the adjustment mechanism also includes a rotating shaft, a locking block, and a slot. The upper and lower inner walls of the buckle are rotatably connected to the rotating shaft. The middle part of the rotating shaft is fixedly fitted with a locking block. The left side of the front end of the strap is provided with evenly distributed slots. The inner end of the locking block is fitted with the slots that are longitudinally adjacent to it for easy locking.

[0009] Furthermore, the adjustment mechanism also includes torsion springs. Torsion springs are fixedly connected between the upper and lower inner walls of the buckle and the upper and lower ends of the vertically adjacent locking blocks, respectively. The torsion springs are respectively sleeved on the upper and lower ends of the rotating shaft to facilitate springback.

[0010] Furthermore, the adjustment mechanism also includes a support rod and a lever. The upper end of the lever is fixedly connected to the support rod, and the upper end of the support rod is fixedly connected to the lever, which facilitates adjustment.

[0011] Furthermore, a rubber ring is provided at the rear edge of the mask to prevent oxygen leakage.

[0012] Furthermore, the rear end of the strap is provided with a sponge pad for easy fitting.

[0013] Furthermore, all the straps are made of silicone for ease of use.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable ventilator mask has the following advantages:

[0015] The straps and connecting straps form a ring that fits over the upper and lower sides of the patient's head. When adjusting the tightness of the straps, the lever and support rod cause the locking block to disengage from the slot. Pulling the straps forward or backward adjusts the tightness. Then, the torsion spring returns the straps to engage with the slot. When using a ventilator mask, the tightness of the straps can be quickly adjusted. Even when the straps are on the patient's head for a long time, they will not leave marks on the patient's head, thus avoiding discomfort. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: an adjustable ventilator mask, including a mask 1, with evenly distributed air holes on the front side of the mask 1, a connecting tube 2 at the air inlet at the front end of the mask 1, a mounting block 4 at the upper end of the mask 1, a T-shaped piece 5 rotatably connected inside the mounting block 4, hooks 7 respectively installed on the left and right sides of the upper end of the T-shaped piece 5, connecting buckles 6 respectively at the left and right ends of the mask 1, hooks 8 respectively installed on the outer ends of the connecting buckles 6, and also includes an adjustment mechanism 9, a rubber ring 3 at the rear edge of the mask 1, and a U-shaped anti-pressure ring at the top of the rubber ring 3, the U-shaped anti-pressure ring being a silicone U-shaped ring;

[0023] Adjustment mechanism 9 includes straps 91, connecting straps 92, and buckles 93. Straps 91 are provided at the right ends of hook 1 7 and hook 2 8 on the right side, and connecting straps 92 are provided at the left ends of hook 1 7 and hook 2 8 on the left side. Buckles 93 are provided at the left ends of the connecting straps 92. The front ends of the straps 91 are fitted with adjacent buckles 93. Adjustment mechanism 9 also includes a rotating shaft 94, a locking block 96, and a slot 97. The rotating shaft 94 is rotatably connected between the upper and lower inner walls of the buckles 93. Locking blocks 96 are fixedly fitted in the middle of the rotating shaft 94. The left side of the front end of the straps 91 is provided with... The evenly distributed slots 97 and the inner ends of the locking blocks 96 are respectively installed in conjunction with the longitudinally adjacent slots 97. The adjustment mechanism 9 also includes torsion springs 95. The upper and lower inner walls of the buckle 93 are respectively fixedly connected to the upper and lower ends of the vertically adjacent locking blocks 96. The torsion springs 95 are respectively sleeved on the upper and lower ends of the rotating shaft 94. The adjustment mechanism 9 also includes support rods 98 and levers 99. The upper ends of the locking blocks 96 are respectively fixedly connected to the support rods 98, and the upper ends of the support rods 98 are respectively fixedly connected to the levers 99. The middle part of the rear end of the straps 91 is respectively provided with sponge pads 10. The straps 91 are all silicone straps. When using the ventilator mask, first install the rubber ring 3 on the face. Next, align the rubber ring 3 with the patient's face, then hook the first hook 7 onto the left and right sides of the upper end of the T-shaped piece 5, and then hook the second hook 8 onto the connecting buckles 6 at both ends. Next, insert the front ends of the straps 91 into the interiors of the longitudinally adjacent buckles 93, and then the locking blocks 96 engage with the adjacent slots 97, thus forming a ring-shaped whole through the straps 91 and the connecting straps 92. Then, place the upper strap 91 over the upper side of the patient's head, aligning the upper sponge pad 10 with the upper middle part of the patient's head, and place the lower strap 91 over the lower side of the head, aligning the lower sponge pad 10 with the lower middle part of the patient's head. When the tightness of the strap 91 needs to be adjusted, squeeze the lever 99, which will cause the support rod 98 to slide inside the annular groove at the upper end of the buckle 93. This will cause the locking block 96 to rotate clockwise under the rotation of the rotating shaft 94, thus disengaging the locking block 96 from the slot 97. Then, pull the strap 91 forward or backward. Pulling the strap 91 forward will tighten it, and pulling the strap 91 backward will loosen it. Then, release the lever 99, and the rotating shaft 94 will rotate counterclockwise under the action of the torsion spring 95. This will cause the locking block 96 to rotate counterclockwise and engage the slot 97. The support rod 98 will also limit the movement at the rear end of the annular groove.

[0024] The working principle of the adjustable ventilator mask provided by this utility model is as follows: When using the ventilator mask, first install the rubber ring 3 at the rear end of the mask 1, then align the rubber ring 3 with the patient's face, then hang the hook 1 7 on the left and right sides of the upper end of the T-shaped piece 5, then hang the hook 2 8 on the connecting buckles 6 at both ends, then insert the front end of the strap 91 into the interior of the longitudinally adjacent buckles 93, and then the locking block 96 engages with the adjacent slots 97, thus forming a ring-shaped whole through the strap 91 and the connecting strap 92, then put the upper strap 91 on the upper side of the patient's head, so that the upper sponge pad 10 is aligned with the upper middle part of the patient's head, and put the lower strap 91 on the lower side of the head. Align the lower sponge pad 10 with the lower center of the patient's head. When adjusting the tightness of the strap 91, squeeze the lever 99, which then drives the support rod 98 to slide inside the annular groove at the upper end of the buckle 93. This causes the locking block 96 to rotate clockwise under the rotation of the rotating shaft 94, thus disengaging the locking block 96 from the slot 97. Then, pull the strap 91 forward or backward. Pulling the strap 91 forward tightens it, while pulling it backward loosens it. Then, release the lever 99, and the rotating shaft 94 will rotate counterclockwise under the action of the torsion spring 95. This causes the locking block 96 to rotate counterclockwise and engage with the slot 97. The support rod 98 then limits the movement by blocking the rear end of the annular groove.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
