Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an oxygen absorption mask assembly. Background Art

[0002] The ICU is a specialized area providing intensive, around-the-clock monitoring and treatment for critically ill patients. Equipped with advanced medical equipment and a dedicated medical team, it manages a variety of critical conditions to ensure stable vital signs and effective disease management. Some ICU patients, unable to breathe independently, require oxygen masks for assisted breathing.

[0003] The mask body of a traditional oxygen mask is directly worn on the patient's face, aligned with the patient's mouth and nose, and is firmly bound by tape or a strap to ensure the stability of the oxygen mask when worn and prevent the oxygen mask from falling off and causing adverse effects.

[0004] The oxygen mask needs to be removed when the patient feels unwell, needs to undergo specific examinations or monitoring, or needs to be observed for autonomous breathing awareness or autonomous language awareness. The patient frequently removes the mask during the observation period, which results in the need to frequently tear off the tape or untie the restraints to release the restraints on the oxygen mask. When putting the mask on again, the tape needs to be re-applied or the restraints need to be fastened, which is very troublesome. Frequent removal of the oxygen mask will also consume a certain amount of tape. Utility Model Content

[0005] The purpose of the utility model is to provide a split oxygen inhalation mask assembly, which effectively solves the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0007] An oxygen mask assembly includes an annular wearing base, a mask body, a skirt and a fastening device. The skirt is fixedly and sealedly arranged on the end surface of the mask body and extends toward the periphery of the mask body. At least two fastening devices are arranged on the side of the annular wearing base. When the oxygen mask is worn, the skirt is pressed and fastened to the upper surface of the annular wearing base by the fastening devices. In addition, the pressing of the skirt can be cancelled by operating the fastening devices.

[0008] It can be seen that the oxygen inhalation mask set has a split design of the annular wearing base and the mask body, and uses a fastening device to press the skirt onto the annular wearing base to achieve the combination of the annular wearing base and the mask body. It only needs to operate the fastening device to cancel the squeezing of the skirt, and the mask body can be quickly removed without completely disassembling the entire mask assembly. It is also easier to put on again, and no materials such as tape will be consumed. It is suitable for situations where the mask is frequently taken off and put on again.

[0009] Furthermore, at least four binding belts are provided on the outer edge surface of the annular wearing base, and the positions of the binding belts are evenly distributed.

[0010] Furthermore, the fastening device includes an L-shaped arm, an adjusting screw and an extrusion block. The L-shaped arm is fixed on the outer edge wall of the annular wearing base. A horizontally through-threaded hole is provided on the L-shaped arm. The adjusting screw is threadedly matched and installed in the threaded hole. The extrusion block is rotatably installed on the end of the adjusting screw. There is a sloped surface above the skirt, and the lower surface of the extrusion block has an inclined surface. The inclined surface is extruded and matched with the inclined surface of the sloped surface.

[0011] Furthermore, a rubber sealing ring is fixed to the lower surface of the skirt. When the skirt is pressed against the annular wearing base, the rubber sealing ring is tightly squeezed between the skirt and the annular wearing base. A pinching handle is installed on the end of the adjusting screw away from the extrusion block, and the outer edge wall of the pinching handle has anti-slip grooves.

[0012] Furthermore, an elastic capsule is fixed below the annular wearing base, and the extension trajectory of the elastic capsule is consistent with the annular wearing base. An inflation and deflation portion is provided on the side of the elastic capsule for inflating or deflation of the elastic capsule.

[0013] Furthermore, the inflation and deflation part includes a catheter, an inflation and deflation port and a connector. The catheter is connected to the side of the elastic sac and communicates with the interior of the elastic sac. The inflation and deflation port is connected to the end of the catheter, and the connector is connected to the end of the inflation and deflation port. The connector can be inserted into the syringe end, and a valve core valve body is also provided in the inflation and deflation port.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0015] 1. The utility model has a split design of the annular wearing base and the mask body, and uses a fastening device to press the skirt onto the annular wearing base to realize the combination of the annular wearing base and the mask body. It only needs to operate the fastening device to cancel the squeezing of the skirt, and the mask body can be quickly removed without completely disassembling the entire mask assembly. It is also easier to put on again, and no materials such as tape will be consumed. It is suitable for situations where the mask is frequently taken off and put on again.

[0016] 2. After the ring-shaped wearing base is firmly bound by the restraining belt, the elastic bladder is inflated by connecting the inflation device to the inflation and deflation part. After inflation, the elastic bladder expands and extends. Due to its elastic effect, it can adaptively deform according to the patient's facial curve, forming a soft sealing filling between the ring-shaped wearing base and the patient's facial skin surface, ensuring good sealing between the ring-shaped wearing base and the patient's facial skin surface, preventing excessive oxygen leakage or a large amount of external air from entering and affecting the oxygen purity, thereby improving the patient's oxygen inhalation quality.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 The utility model provides an oxygen mask assembly, including an annular wearing base 1, a mask body 2, a skirt 3 and a fastening device 4. The skirt 3 is fixedly and sealedly arranged on the end surface of the mask body 2 and extends toward the periphery of the mask body 2. At least two fastening devices 4 are arranged on the side of the annular wearing base 1. When the oxygen mask is worn, the skirt 3 is pressed tightly and bound to the upper surface of the annular wearing base 1 through the fastening device 4. In addition, the pressure on the skirt 3 can be cancelled by operating the fastening device 4.

[0024] When wearing the oxygen mask, first, the annular wearing base 1 is fastened to the patient's face, and the patient's mouth and nose are exposed from the middle of the annular wearing base 1. Then, the skirt 3 is placed on the annular wearing base 1, and the fastening device 4 is operated to press the skirt 3 onto the annular wearing base 1. In this way, the oxygen mask is worn and can meet the patient's oxygen inhalation needs.

[0025] When the mask body 2 needs to be removed, the mask body 2 and the skirt 3 can be quickly removed from the annular wearing base 1 by operating the fastening device 4 to cancel the squeezing of the skirt 3. When wearing again, the skirt 3 can be pressed against the annular wearing base 1 again using the fastening device 4.

[0026] The oxygen inhalation mask assembly is designed with a split ring-shaped wearing base 1 and a mask body 2. The skirt 3 is pressed against the ring-shaped wearing base 1 by a fastening device 4 to realize the combination of the ring-shaped wearing base 1 and the mask body 2. It is only necessary to operate the fastening device 4 to cancel the squeezing of the skirt 3. Without completely disassembling the entire mask assembly, the mask body 2 can be quickly removed, and it is easier to put on again without consuming materials such as tape. It is suitable for situations where the mask is frequently taken off and put on again.

[0027] Specifically, at least four straps 11 are provided on the outer edge surface of the annular wearing base 1, and the straps 11 are evenly distributed. When wearing, the annular wearing base 1 needs to be placed on the patient's face first, and the annular wearing base 1 needs to be firmly bound by the straps 11.

[0028] Specifically, the fastening device 4 includes an L-shaped arm 41, an adjusting screw 42 and an extrusion block 43. The L-shaped arm 41 is fixed to the outer edge wall of the annular wearing base 1. A horizontally through-threaded hole 411 is provided on the L-shaped arm 41. The adjusting screw 42 is threadedly matched and installed in the threaded hole 411. The extrusion block 43 is rotatably installed on the end of the adjusting screw 42. The skirt 3 has a sloped surface 31 above, and the lower surface of the extrusion block 43 has an inclined surface 431. The inclined surface 431 is extruded with the inclined surface 31 to fit the skirt 3 on the upper surface of the annular wearing base 1. By tightening the adjusting screw 42, the extrusion block 43 is pushed to extrude the inclined surface 31, and the skirt 3 can be limited and pressed on the annular wearing base 1 to realize the combination of the mask body 2 and the annular wearing base 1.

[0029] When the mask body 2 needs to be removed, the adjusting screw 42 is screwed in the reverse direction to drive the extrusion block 43 to gradually separate from the slope surface 31, and finally the extrusion of the skirt 3 is cancelled, so that the mask body 2 and the skirt 3 can be quickly removed from the annular wearing base 1 as a whole.

[0030] Specifically, a rubber sealing ring 32 is fixed to the lower surface of the skirt 3. When the skirt 3 is pressed against the annular wearing base 1, the rubber sealing ring 32 is tightly squeezed between the skirt 3 and the annular wearing base 1. The rubber sealing ring 32 plays an extrusion sealing effect, ensuring good sealing between the skirt 3 and the annular wearing base 1, and preventing excessive leakage of oxygen or a large amount of external air from entering and affecting the oxygen purity.

[0031] A pinch handle 421 is installed on the end of the adjusting screw 42 away from the extrusion block 43. By pinching the pinch handle 421, the contact area with the fingers is increased, making it convenient to exert force to screw and adjust the adjusting screw 42. The outer edge wall of the pinch handle 421 has anti-slip grooves to increase the friction between the fingers and avoid slipping.

[0032] Specifically, an elastic bag 5 is fixed under the annular wearing base 1, and the extension trajectory of the elastic bag 5 is consistent with the annular wearing base 1. The side of the elastic bag 5 is provided with an inflation and deflation part 6, which is used to inflate or deflate the elastic bag 5. When the annular wearing base 1 is worn, the elastic bag 5 is attached to the patient's facial surface. After the annular wearing base 1 is firmly bound by the restraint belt 11, the elastic bag 5 is inflated by connecting the inflation device to the inflation and deflation part 6. After inflation, the elastic bag 5 expands and extends. Due to its elastic effect, it can adapt to the deformation according to the curve of the patient's face, forming a soft sealing filling between the annular wearing base 1 and the patient's facial skin surface, ensuring good sealing between the annular wearing base 1 and the patient's facial skin surface, avoiding excessive leakage of oxygen or a large amount of external air entering and affecting the oxygen purity, thereby improving the patient's oxygen inhalation quality.

[0033] Specifically, the inflation / deflation unit 6 includes a conduit 61, an inflation / deflation port 62, and a connector 64. The conduit 61 is connected to the side of the elastic bladder 5 and communicates with the interior of the elastic bladder 5. The inflation / deflation port 62 is connected to the end of the conduit 61. The connector 64 is connected to the end of the inflation / deflation port 62. The connector 64 can be inserted into the end of the inflation / deflation port 62. A valve core body 63 is also provided in the inflation / deflation port 62. The working principle of the valve core body 63 is the same as that of the valve core on a bicycle tire.

[0034] When inflating the elastic sac 5, the syringe head is inserted into the connector 64, and the end face of the syringe head is used to squeeze the convex column on the valve core valve body 63 and retract it, so that the syringe can inject gas into the elastic sac 5 through the valve core valve body 63, the charging and discharging port 62 and the conduit 61 in sequence to achieve inflation. When deflating, a sharp object is inserted into the valve core valve body 63 to squeeze the convex column and retract it, and the gas in the elastic sac 5 is discharged through the conduit 61, the charging and discharging port 62, the valve core valve body 63 and the connector 64 to achieve deflation of the elastic sac 5.

[0035] In addition, the connector 64 is adaptively connected to the syringe, which is a common medical device that is simple to operate and easy to obtain, thereby eliminating the need for additional inflation devices and providing high practicality.

[0036] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and the performance or use are the same, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
