Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an airbag protection device. Background Art

[0002] The laryngeal mask is a supraglottic ventilation device, which is an airway device that can be inserted into the pharynx to achieve ventilation, oxygen supply and anesthetic gas administration without the need for endotracheal intubation. It is widely used in airway management during anesthesia and emergency treatment.

[0003] The existing laryngeal mask comprises a mask body, a cannula, an inflation tube and an inflation valve. The mask body has a breathing chamber for communicating with the respiratory tract, one end of the cannula is communicated with the breathing chamber, and the other end is used to connect to the breathing device, and the inflation tube is used to inflate the mask body, one end of which is communicated with the mask body, and the other end is connected to the inflation valve, and the inflation valve can be inserted with a syringe to inflate the mask body.

[0004] With regard to the above-mentioned related technologies, when the laryngeal mask is in use, the tube needs to be inserted from the patient's mouth into the throat. At this time, the patient's mouth needs to remain open for a long time, and the patient's teeth will come into contact with the tube or even be squeezed, which may easily cause damage to the tube by the teeth. Therefore, there is room for improvement. Utility Model Content

[0005] In order to reduce the damage caused by the patient's teeth to the laryngeal mask and ensure the normal progress of treatment, the present application provides an airbag protection device.

[0006] The present application provides an airbag protection device that adopts the following technical solution:

[0007] An airbag protection device comprises an integrally connected shielding cover and an extension portion, wherein the shielding cover is provided with a clearance notch for a laryngeal mask to pass through, and the shielding cover is used for a patient to bite; the extension portion is arranged at one end of the shielding cover, and the extension portion is used to limit the shielding cover from being swallowed into the patient's mouth.

[0008] By adopting the above technical solution, when it is necessary to treat the patient, the cannula of the laryngeal mask can be first stuck in the gap, and then the cannula can be inserted into the patient's throat. After the insertion is completed, the doctor adjusts the position of the shielding cover so that the shielding cover is contained in the patient's mouth; because the cannula is protected by the shielding cover, the patient's teeth are prevented from directly biting the cannula, thereby reducing the damage to the laryngeal mask. At the same time, after the patient bites the shielding cover, the extension part is located outside the patient's mouth. The existence of the extension part can limit the patient from completely containing the shielding cover in his mouth, making it convenient to take out the entire bite device after the treatment is completed.

[0009] Preferably, the shielding cover and the extending portion are both made of hard plastic material.

After the patient bites on the shielding cover, the pressure of the shielding cover and the extension part on the patient can be reduced, thereby improving the comfort level during treatment.

[0013] Preferably, one end of the shielding cover away from the extending portion is integrally connected with a reinforcing portion, and the reinforcing portion is arranged along the circumference of the shielding cover.

[0014] By adopting the above technical solution, the reinforcement part can play a reinforcing role, thereby improving the bending resistance of the shielding cover.

[0015] Preferably, it further comprises a binding strap, wherein the binding strap is arranged on the extension portion.

[0016] By adopting the above technical solution, the strap is connected to the extension part. After the patient bites the hood, the strap can be tied on the patient's head or ears, thereby limiting the position of the entire bite device, and the patient does not need to use his hands to maintain the position of the bite device all the time.

[0017] Preferably, a mounting hole is provided on the extension portion, and two ends of the binding strap are detachably connected to the mounting hole.

[0018] By adopting the above technical solution, the end of the strap passes through the mounting hole, thereby connecting to the extension portion. The strap can be connected by tying a slipknot or stapled to achieve detachability. After the bite device is discarded, the strap and the shielding cover can be separated from each other for separate recycling.

[0019] Preferably, the strap is made of elastic material.

[0020] By adopting the above technical solution, the strap made of elastic material has good elastic deformation ability, so that the strap can be better put on the back of the patient's head.

[0021] Preferably, an elastic layer is provided on the inner wall of the clearance gap, and the elastic layer is made of elastic material.

[0022] By adopting the above technical solution, the elastic layer has good deformation ability, and when the cannula is set in the clearance gap, the softness of the contact between the cannula and the shielding cover can be increased.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By providing the shielding cover and the extension part, the laryngeal mask passes through the gap and extends into the patient's throat. The shielding cover is held in the patient's mouth and the cannula is protected by the shielding cover, thereby preventing the patient's teeth from directly biting the cannula, thereby reducing damage to the laryngeal mask.

[0035] The present application embodiment discloses an airbag protection device. Figure 1 The airbag protection device includes a shielding cover 1 and an extension part 2 which are integrally connected. The shielding cover 1 is cylindrical, and a clearance gap 3 is provided on the outer surface of the shielding cover 1. The clearance gap 3 is arranged along the length direction of the shielding cover 1. The clearance gap 3 is used for the laryngeal mask intubation tube to pass through, and the shielding cover 1 is used for the patient to bite. The extension part 2 is connected to one end of the shielding cover 1, and the extension part 2 is plate-shaped and is used to limit the shielding cover 1 from being completely swallowed into the patient's mouth. Among them, the shielding cover 1 and the extension part 2 are both made of hard plastic materials, and the hard plastic materials can be but are not limited to polyvinyl chloride, polystyrene, etc. These hard plastic materials have the advantages of light weight, low cost, safety and non-toxicity, and are suitable for making disposable medical supplies without causing harm to the health of patients.

[0036] When the patient needs to be treated, the cannula of the laryngeal mask can be first stuck in the gap 3, and then the cannula can be inserted into the patient's throat. After the insertion is completed, the doctor adjusts the position of the shielding cover 1 so that the shielding cover 1 is contained in the patient's mouth; because the cannula is protected by the shielding cover 1, the patient's teeth are prevented from directly biting the cannula, thereby reducing damage to the laryngeal mask. At the same time, after the patient bites the shielding cover 1, the extension part 2 is located outside the patient's mouth. The existence of the extension part 2 can limit the patient from completely containing the shielding cover 1 in the mouth, and it is convenient to take out the entire bite device after the treatment is completed.

[0037] Specifically, the edge of the shielding cover 1 and the edge of the extension part 2 are both in an arc shape. The end of the shielding cover 1 away from the extension part 2 is integrally connected with a reinforcement part 4, and the reinforcement part 4 is arranged along the circumference of the shielding cover 1. The arc-shaped structure itself has good softness. After the patient bites the shielding cover 1, the pressure of the shielding cover 1 and the extension part 2 on the patient can be reduced, thereby improving the comfort level during treatment.

[0038] In addition, an elastic layer (not shown in the figure) is fixedly connected to the inner wall of the clearance notch 3, and the elastic layer is made of elastic material, and the elastic material includes but is not limited to rubber, elastomeric plastic, etc. The elastic layer has good deformation ability, and when the cannula is set in the clearance notch 3, the softness of the contact between the cannula and the shielding cover 1 can be increased.

[0039] According to some embodiments of the present application, optionally, please refer to Figure 2 The bite device also includes a strap 5, which is made of elastic material and connected to the extension part 2. The strap 5 is used to be placed on the patient's brain. After the patient bites the shield 1, the strap 5 can be tied on the patient's head or ears to limit the position of the entire bite device, and the patient does not need to use his hands to maintain the position of the bite device all the time.

[0040] Specifically, a plurality of mounting holes 6 are provided on the surface of the extension part 2. In this embodiment, the number of mounting holes 6 is three, and the number of straps 5 is two. The ends of the straps 5 are detachably connected to the mounting holes 6. The ends of the straps 5 can pass through the mounting holes 6 and be folded in half, and then stapled together with staples. Of course, the straps 5 can also be tied with a slipknot to achieve the detachability of the straps 5 and the extension part 2. After the bite device is discarded, the straps 5 and the shielding cover 1 can be separated from each other to achieve separate recycling.

[0041] The implementation principle of the airbag protection device of the embodiment of the present application is as follows: when the patient needs to be treated, the cannula of the laryngeal mask can be first stuck in the gap 3, and then the cannula can be inserted into the patient's throat. After the insertion is completed, the doctor adjusts the position of the shielding cover 1 so that the shielding cover 1 is contained in the patient's mouth, and at the same time puts the strap 5 on the back of the patient's head.

[0042] During treatment, the cannula is protected by the shielding cover 1, thereby preventing the patient's teeth from biting the cannula directly, thereby reducing damage to the laryngeal mask. In addition, after the patient bites the shielding cover 1, the extension part 2 is located outside the patient's mouth. The presence of the extension part 2 can limit the patient from completely holding the shielding cover 1 in the mouth, making it convenient to take out the entire bite device after the treatment is completed.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
