Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilators, specifically a wearing structure for ventilators. Background Technology
[0002] A ventilator oxygen mask is a medical device used to deliver oxygen to patients or assist with mechanical ventilation. It is usually made of soft material and uses a fastening strap to ensure a seal and prevent oxygen leakage. It connects to a ventilator or oxygen supply system via a connecting tube and can adjust the oxygen concentration and ventilation pressure as needed. It is suitable for scenarios such as surgery, intensive care, or respiratory failure.
[0003] Chinese patent CN213911879U discloses a wearable ventilator mask structure, including a main body. A fixing group is provided at the top of the main body. A connecting seat is connected between the main body and the fixing group. The connecting seat consists of two parts, and a movable block is connected between the two parts. A rotating block is fixed at the bottom of the movable block. One end of the connecting seat has a rotating groove adapted to the rotating block. The rotating block rotates inside the rotating groove. A connecting block is fixed at the top of the movable block. The other end of the connecting seat has a connecting groove. The connecting block is inserted into the connecting groove and connected by threads.
[0004] Although the aforementioned patent allows for adjustable distance between the fixed assembly and the main body through the design of connecting blocks, movable blocks, rotating blocks, and rotating grooves, and enables the size of the device to be adjusted according to needs, making the device fit the patient's face more closely and thus facilitating its use, the mask still suffers from the problem of relying on a rigid structure for sealing and manual adjustment, resulting in poor adaptability to different face shapes and a tendency to leak air or cause localized pressure. Utility Model Content
[0005] The purpose of this invention is to provide a wearing structure for a ventilator to solve the problems of existing devices that rely on rigid structures for sealing and require manual adjustment, resulting in poor adaptability to different face shapes and easy leakage or local pressure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wearing structure for a ventilator, including an oxygen mask, wherein connecting blocks are fixedly connected to both sides and the front of the oxygen mask, and straps are connected inside the connecting blocks; a docking ring is fixedly connected to the top of the oxygen mask; an airtight structure is provided at the bottom of the oxygen mask; a hollow interlayer is provided inside the oxygen mask; several connecting grooves are provided through the bottom of the hollow interlayer; and several air delivery grooves are provided on the inner wall of the oxygen mask.
[0007] Preferably, the airtight structure includes an air cushion, which is fixedly connected to the bottom of the oxygen mask, the air delivery channel is connected to the hollow interlayer, and the connecting channel is connected to the interior of the air cushion.
[0008] Preferably, the air cushion has a plurality of venting grooves extending through its inner wall, the number of venting grooves being less than the number of connecting grooves.
[0009] Preferably, a docking ring is fixedly connected to the top of the oxygen mask, and the docking ring is in communication with the interior of the oxygen mask.
[0010] Preferably, the oxygen mask has a connecting ring fixedly connected to the top of its interior, and the inner wall of the connecting ring has several docking grooves that are connected to the gas delivery groove.
[0011] Preferably, the inner wall of the connecting ring is fixedly connected with a plurality of air-blocking blocks, the positions of which correspond to the positions of the docking grooves.
[0012] Preferably, the air baffle is set in an inclined state, and the docking groove is also set in an inclined state.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1) By using the adaptive expansion of the air cushion to fit the patient's facial contours, the oxygen mask can reduce local pressure while ensuring a tight seal, thus actively adapting to different facial features and effectively improving the universality of medical equipment.
[0015] 2) By varying the number of venting grooves and connecting grooves, a dynamic air pressure balance is achieved, maintaining the air cushion's support while avoiding over-expansion caused by continuous inflation, thus providing a dual guarantee of flexible sealing and pressure safety.
[0016] 3) By optimizing the oxygen distribution path through the guiding effect of the air block, the inflation efficiency of the air cushion is improved while ensuring normal oxygen supply to the patient, thus forming a collaborative working mechanism between the main oxygen supply channel and the auxiliary sealing system.

[0023] 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.
[0024] Example 1
[0025] Combination Figures 1-5 A ventilator wearing structure includes an oxygen mask 1, with connecting blocks 2 fixedly connected to both sides and the front of the oxygen mask 1, straps 3 connected inside the connecting blocks 2, a docking ring 4 fixedly connected to the top of the oxygen mask 1, an airtight structure 5 provided at the bottom of the oxygen mask 1, a hollow interlayer 8 opened inside the oxygen mask 1, a plurality of connecting grooves 10 opened through the bottom of the hollow interlayer 8, and a plurality of air delivery grooves 9 opened on the inner wall of the oxygen mask 1.
[0026] In actual operation, the oxygen mask 1 is fixed to the patient's mouth and nose by the strap 3, and then the docking ring 4 is connected to the external oxygen delivery tube to deliver oxygen to the patient.
[0027] When oxygen is delivered to the inside of the oxygen mask 1, some oxygen will enter the inside of the hollow sandwich layer 8 through several gas delivery channels 9, and then be delivered to the inside of the air cushion 6 through several connecting channels 10, causing the air cushion 6 to expand, thereby closely fitting the patient's face and adapting to the patient's facial curve, thus improving the airtightness of the oxygen mask 1.
[0028] The airtight structure 5 includes an air cushion 6, which is fixedly connected to the bottom of the oxygen mask 1. The air delivery channel 9 is connected to the hollow interlayer 8, and the connecting channel 10 is connected to the interior of the air cushion 6.
[0029] The air cushion 6 has several air venting grooves 7 that penetrate its inner wall. The number of air venting grooves 7 is less than the number of connecting grooves 10.
[0030] Specifically, after oxygen enters the air cushion 6, it enters the oxygen mask 1 through the venting grooves 7. Since the number of venting grooves 7 is less than the number of connecting grooves 10, the air intake speed of the air cushion 6 is greater than the air release speed. Therefore, the air cushion 6 will expand first to fit the patient's face and prevent the air cushion 6 from over-expanding.
[0031] A docking ring 4 is fixedly connected to the top of the oxygen mask 1, and the docking ring 4 is connected to the inside of the oxygen mask 1.
[0032] The oxygen mask 1 has a connecting ring 11 fixedly connected to the top of the interior. The inner wall of the connecting ring 11 has several docking grooves 12, which are connected to the gas delivery groove 9.
[0033] Several air baffles 13 are fixedly connected to the inner wall of the connecting ring 11, and the positions of the air baffles 13 correspond to the positions of the docking groove 12.
[0034] Specifically, when oxygen enters the oxygen mask 1 through the docking ring 4, some of the oxygen will be blocked by several air-blocking blocks 13 and thus enter the interior of the docking groove 12. Therefore, it will then enter the interior of the air cushion 6 through the air delivery groove 9 and the connecting groove 10. Thus, by increasing the amount of oxygen entering the hollow interlayer 8 through the air-blocking blocks 13, the expansion speed of the air cushion 6 is increased.
[0035] The air baffle 13 is set in an inclined state, and the docking groove 12 is also set in an inclined state.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
