Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a multifunctional cap - type ventilator mask. Background Art

[0002] In the modern medical field, as an important life - support device, ventilators are widely used in the treatment of various patients with respiratory dysfunction; and the ventilator mask is a key component connecting the ventilator and the patient, and its performance directly affects the treatment effect and the patient's comfort. At present, the existing clinical ventilator masks mainly have the following problems: The existing ventilator masks are usually fixed by a neck strap when worn. After long - term use, the neck strap is prone to deformation, resulting in insecure fixation of the mask and easy slipping. This not only affects the treatment effect but also increases the discomfort of the patient and the workload of the nursing staff. And because the ventilator mask needs to be frequently cleaned and disinfected to ensure hygiene and safety. However, after multiple cleanings and disinfections, the material of the neck strap is easily damaged and its elasticity is reduced, further exacerbating the problem of insecure fixation. In addition, the existing ventilator masks have relatively single functions and often only focus on the realization of the breathing function. For some patients, mouth breathing is a common situation, but the existing masks cannot effectively prevent excessive air flow from entering the stomach through the mouth, which may cause problems such as stomach discomfort.

The top surface of the sliding rod is fixedly connected to a guide plate. The bottom surface of the other end of the guide plate is fixedly installed with a support rod, and the bottom surface of the support rod is fixedly installed with a partition plate, and the bottom surface of the partition plate is fixedly connected to an adjusting plate. The adjusting plate is slidably sleeved outside the column. The bottom of the column is fixedly connected to the mounting frame, the top of the column is fixedly connected to a limiting plate, and a spring frame is sleeved outside the column; A plurality of exhalation holes are evenly formed on one surface of the mounting frame.

[0008] Preferably, one end of the spring frame is fixedly connected to the surface of the limiting plate, and the other end of the spring frame is fixedly connected to the surface of the adjusting plate.

[0009] Preferably, a silica gel sleeve is sleeved outside the bite plate.

[0010] Preferably, the fixing band A is adhesively bonded to the surface of the upper adjusting band through a magic tape, and the fixing band B is also adhesively bonded to the surface of the lower adjusting band through a magic tape.

[0011] Preferably, a rubber pad is fixedly arranged on the inner wall of the forehead support frame.

[0012] Preferably, an anti-fog coating is coated on the inner surface of the mask shell or the mask shell is made of anti-fog material.

The rubber pad on the inner wall of the forehead support also increases the wearing comfort, and the multiple slots on the surface of the fixing hood improve the air permeability. Through this design, the wearing comfort of patients is further improved.

[0015] In the present invention, a breathing adjustment mechanism is arranged inside the mask shell. When wearing the mask, when the patient bites the bite plate in the breathing adjustment mechanism, through the linkage of components such as the sliding rod, guide plate, support rod, baffle plate, and adjustment plate, when the patient breathes through the mouth, the baffle plate moves upward to fit the patient's lips under the action of the spring frame, thereby driving the position of the baffle plate to be adjusted, so that the baffle plate blocks a part of the exhalation holes. Thus, when the patient breathes with the mouth open, it effectively prevents too much air flow from entering the stomach through the oral cavity, reducing problems such as stomach discomfort.

A fixing headgear 12 is fixedly installed on the bottom surface of the head fixing band 1. The forehead support frame 3 is fixedly connected to the mask body assembly 7 through a connecting rod 11. A respiratory adjustment mechanism 94 is fixedly arranged in the mask body assembly 7.

[0022] Refer to Figure 4 , the mask body assembly 7 includes a mask shell 91. A pipeline interface 92 is fixedly arranged on the surface of the mask shell 91. A breathable cushion 93 is arranged at the part of the mask shell 91 in contact with the patient's face. The breathable cushion 93 is made of medical - grade sponge material, and a plurality of breathable holes are designed on the surface of the sponge material; This design can effectively prevent the occurrence of facial pressure sores.

[0023] Refer to Figure 5 , the respiratory adjustment mechanism 94 includes a mounting frame 13. The mounting frame 13 is fixedly installed on the inner wall of the mask shell 91. An airbag sleeve 14 is adhered to the inner wall of the mounting frame 13. A bite plate 15 is movably arranged in the middle of the airbag sleeve 14; A sliding rod 16 is fixedly installed at the top of the occlusal plate 15, and the sliding rod 16 slidably penetrates through the airbag sleeve 14 and the mounting frame 13. The top surface of the sliding rod 16 is fixedly connected to the guide plate 17. The bottom surface of the other end of the guide plate 17 is fixedly installed with a support rod 19, and the bottom surface of the support rod 19 is fixedly installed with a partition plate 20. The bottom surface of the partition plate 20 is fixedly connected to the adjusting plate 22. The adjusting plate 22 is slidably sleeved on the outside of the column 21. The bottom of the column 21 is fixedly connected to the mounting frame 13. The top of the column 21 is fixedly connected to the limiting plate 24. A spring frame 23 is sleeved on the outside of the column 21; A plurality of air exhalation holes 18 are evenly formed on one surface of the mounting frame 13; when the patient opens the mouth, the occlusal plate 15 and the partition plate 20 can move upward under the action of the spring frame 23, so that the partition plate 20 blocks the air exhalation holes 18 on the surface of the mounting frame 13, reducing the amount of air flowing through the oral cavity into the stomach.

[0024] Refer to Figure 5 , one end of the spring frame 23 is fixedly connected to the surface of the limiting plate 24, and the other end of the spring frame 23 is fixedly connected to the surface of the adjusting plate 22.

[0025] A silica gel sleeve is sleeved on the outside of the occlusal plate 15.

[0026] Refer to Figure 2 , the fixing band A4 is adhesively bonded to the surface of the upper adjusting band 2 through a magic tape, and the fixing band B8 is also adhesively bonded to the surface of the lower adjusting band 7 through a magic tape; specifically, the fixing band A4 and the fixing band B8 are fixed at appropriate positions on the upper adjusting band 2 and the lower adjusting band 7 through the magic tape to ensure that the mask shell 91 is firmly worn and fixed.

[0027] A rubber pad is fixedly installed on the inner wall of the forehead support frame 3.

[0028] An anti-fog coating is applied to the inner surface of the mask shell 91 or the mask shell 91 is made of an anti-fog material.

[0029] Refer to Figures 2-3 , the top fixing band 1, the upper adjusting band 2, the fixing band A4, the connecting band 5, the stabilizing pad band 6, the lower adjusting band 7, the fixing band B8, the mask body assembly 7, and the fixing headgear 12 are all made of soft elastic fabrics, and a plurality of slot holes are formed on the surface of the fixing headgear 12.

[0030] In the present invention, when in use, the multifunctional cap-type ventilator mask is worn on the patient's head, and the lengths of the upper adjusting band 2 and the lower adjusting band 7 are adjusted according to the size of the patient's head to make the mask shell 91 closely fit the patient's face; specifically, the fixing band A4 and the fixing band B8 are fixed at appropriate positions on the upper adjusting band 2 and the lower adjusting band 7 through the magic tape to ensure that the mask shell 91 is firmly worn and fixed; among them, the position of the forehead support frame 3 is adjusted to make it comfortably fit the patient's forehead, and the rubber pad on the inner wall of the forehead support frame 3 can increase the wearing comfort; It should be noted that during the wearing process, the patient's lips or teeth can bite the occlusal plate 15, so that the occlusal plate 15 moves downward to the middle of the lips against the elastic force of the spring frame 23; during this wearing process, the airbag sleeve 14 fits closely with the patient's lips; When the patient uses a ventilator, if the patient breathes with an open mouth, the occlusal plate 15 bitten by the patient moves upward against the elastic force of the spring frame 23 and presses closely against the patient's lips or upper teeth. During this process, components such as the sliding rod 16, the guide plate 17, the support rod 19, the partition plate 20, and the adjusting plate 22 are also linked by the elastic force of the spring frame 23, so that the partition plate 20 blocks the air holes 18 on the surface of the mounting frame 13 to a certain extent. In this way, when the patient breathes with an open mouth, it can effectively prevent excessive airflow from entering the stomach through the oral cavity and reduce problems such as stomach discomfort; If there is fog on the mask, the fog can be removed by wiping or other means. Since the inner surface of the mask shell 91 is coated with an anti-fog coating or made of an anti-fog material, it can effectively reduce the generation of fog and improve the visibility and comfort of the patient; When wearing the mask for a long time, the air holes on the surface of the breathable pad 93 can keep the facial skin dry and effectively prevent the occurrence of facial pressure sores; moreover, the multiple slot holes on the surface of the fixed headgear 12 also improve the air permeability of the entire mask and further improve the comfort of the patient wearing it; and the fixed headgear 12 can be made of silica gel material, so as to provide a certain degree of elasticity and better adapt to the size and shape of the heads of different patients.
