Description

Technical Field

[0001] The utility model relates to a medical tool, in particular to a protection device for preventing oral aspiration. Background Technique

[0002] For oral surgeries under general anesthesia, in order not to affect the intraoperative oral operation, more than 98% of cases require nasal intubation. The conventional position is with the head tilted backward, and an oral retractor is routinely used during the operation to fully expose the oral cavity. As a result, a hole is formed among the glossopalatine arch, uvula and root of the tongue. Foreign bodies such as bone debris, tooth stumps, and irrigation fluid during the operation are easy to enter but difficult to exit. After entering the hole, there are anatomical parts such as the epiglottis, bilateral arytenoid cartilages, hypopharynx, postcricoid area, and piriform fossa, with complex structures. Once foreign bodies enter, it is very difficult to aspirate them out through repeated intraoperative irrigation.

[0003] If it accidentally enters the trachea, it seriously threatens the life of the patient. Although there is an airbag at the bottom of the tracheal catheter to fix the pipeline and prevent foreign bodies from entering the airway, there is no better protection measure for the approximately 10 cm long distance from the oropharynx to the airbag. Foreign bodies can enter the esophagus or airway with the changes in body position, irrigation, negative pressure aspiration and other operations, such as bone fragments, tooth remnants or broken ends of instruments; if it enters the esophagus, it can also cause adverse consequences such as mucosal damage. To prevent any possible adverse factors that may harm the patient and take precautions, an oropharyngeal barrier is designed to seal the hole formed by the root of the tongue and the glossopalatine arch, that is, to block foreign bodies from the entrance and prevent all possible foreign bodies from entering, forming a protective barrier.

[0004] This device can be fixed, does not damage the oral mucosa, has safe materials, suitable shape and size, and is suitable in hardness and softness. It can fit and seal with the mucosa, and cannot enter the oropharynx, facilitating the treatment operation in the mouth. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the above background technique and provide a protection device for preventing oral aspiration.

[0006] A protection device for preventing oral aspiration includes a handle, a mucosa-fitting part, a connecting part and anti-detachment wings. The handle is arranged at the top of the connecting part, and the anti-detachment wings are arranged at the bottom of the connecting part. The outer surface of the anti-detachment wings is conical. A mucosa-fitting part is arranged between the handle and the connecting part. The outer surface of the mucosa-fitting part is inversely conical, and the thickness of the mucosa-fitting part decreases from inside to outside. A cavity is formed after the inner side walls of the handle, the connecting part and the anti-detachment wings are connected;

[0007] It further includes an inflatable fitting device, which includes an airbag, several branch air ducts, a main air duct, an exhaust pipe, an exhaust pipe plug, a one-way air valve and a connection port. The airbag is annularly arranged on the outer side wall of the connecting part. The branch air ducts are evenly distributed in a ring shape. One end of each branch air duct passes through the inner side wall of the connecting part and communicates with the inside of the airbag. The other ends of the branch air ducts converge and are connected to the bottom of the main air duct.

[0017] Please refer to Figures 1 to 7 As shown, a protection device against oral aspiration includes a handle 1, a mucosa fitting part 2, a connecting part 3 and an anti-detachment wing 4. The handle 1 is arranged at the top of the connecting part. The anti-detachment wing 4 is arranged at the bottom of the connecting part 3. The outer surface of the anti-detachment wing 4 is conical. A mucosa fitting part 2 is arranged between the handle 1 and the connecting part 3. The outer surface of the mucosa fitting part 2 is inversely conical, and the thickness of the mucosa fitting part 2 decreases from inside to outside. A cavity 5 is formed after the inner side walls of the handle 1, the connecting part 3 and the anti-detachment wing 4 are connected;

[0018] Specifically, the whole device is integrally formed by a hydrocolloid material, with a soft and transparent texture. After the tracheal intubation is inserted into a general anesthesia patient during oral surgery, this device is placed inside the patient's oral cavity. Since the device has a soft texture and an internal cavity 5, the device is pinched into deformation with a surgical forceps. The anti-detachment wing 4 is placed at the patient's larynx and then the surgical forceps are released. The anti-detachment wing 4 is stretched out, and the device is clamped at the patient's larynx. Then, the handle 1 is gently pressed to make the mucosa fitting part 2 fit with the oral mucosa. Since the thickness of the mucosa fitting part 2 decreases from inside to outside, the edge is more likely to fit with the patient's oral mucosa and has a good degree of fit. Then, oral surgery is performed on the patient. At this time, the foreign bodies generated will be blocked outside the larynx by the mucosa fitting part 2. After the surgery is completed and the oral cavity is cleaned, the edge of the mucosa fitting part 2 is gently pried to make the mucosa fitting part 2 separate from the cavity mucosa. Then, the handle 1 is gently pulled to take out the device from the cavity. Since the device has a soft texture, when the handle 1 is pulled, the anti-detachment wing 4 is deformed under the extrusion of the larynx, and the device can be easily taken out from the larynx;

[0019] It further includes an inflation fitting device 6. The inflation fitting device 6 includes an airbag 61, several branch air ducts 62, a main air duct 63, an exhaust duct 64, an exhaust duct plug 65, a one-way air valve 66 and a connection port 67. The airbag 61 is annularly arranged on the outer side wall of the connecting part 3. The branch air ducts 62 are annularly and evenly distributed. One end of the branch air duct 62 passes through the inner side wall of the connecting part 3 and communicates with the inside of the airbag 61. The other ends of the branch air ducts 62 converge and are connected to the bottom of the main air duct 63. The top end of the main air duct 63 passes through the handle 1. A connection port 67 is arranged at the top end of the main air duct 63. The connection port 67 is used to connect an external gas injection device. An exhaust duct 64 is also arranged on the side wall of the main air duct 63. An exhaust duct plug 65 is arranged at the tail end of the exhaust duct 64. A one-way air valve 66 is arranged on the main air duct 63 between the connection port 67 and the exhaust duct 64;

[0020] Specifically, in order to make the device fit better with the larynx and at the same time construct a second barrier against foreign objects, we added an inflatable fitting device 6 on the basis of the technology of the original embodiment. For a patient undergoing oral surgery under general anesthesia, after the tracheal intubation is inserted, the device is placed inside the patient's oral cavity. Since the device is soft in texture and has a cavity 5 inside, the device is pinched into deformation with surgical forceps. The anti-detachment wing 4 is placed at the patient's larynx and then the surgical forceps are released. The anti-detachment wing 4 is stretched out, and the device is clamped at the patient's larynx. Then, the handle 1 is gently pressed to make the mucosal fitting part 2 fit with the oral mucosa. Since the thickness of the mucosal fitting part 2 decreases from the inside to the outside, the edge is more likely to fit with the patient's oral mucosa and has a good degree of fit. Then, the connection port 67 is connected to a syringe, and air is injected into the main trachea 63 through the syringe. The air enters the inside of the airbag 61 via the main trachea 63, the one-way air valve 66, and the branch trachea 62. The several annularly distributed branch tracheas 62 can make the inflation of the airbag 61 more uniform. Since the device is soft and transparent in texture, when it is seen that the connection part 3 is slightly deformed under the action of the airbag 61, it means that the outer wall of the airbag 61 has fit with the inside of the throat. Then, an oral surgery is performed on the patient. At this time, the foreign objects generated will be blocked outside the larynx by the mucosal fitting part 2 and the airbag 61. When the surgery is over, the oral cavity is cleaned. After the cleaning is completed, the exhaust pipe plug 65 at the end of the exhaust pipe 64 is opened, so that the gas inside the airbag 61 is discharged through the exhaust pipe 64. The outer wall of the airbag 61 is separated from the inside of the throat. Then, the edge of the mucosal fitting part 2 is gently pried to make the mucosal fitting part 2 separate from the cavity mucosa. Then, the handle 1 is gently pulled to take the device out of the cavity. Since the device is soft in texture, when the handle 1 is pulled, the anti-detachment wing 4 is deformed under the extrusion of the larynx, and it is very easy to take the device out of the larynx.

[0021] The working principle and process of the present utility model:

[0022] Please refer to Figures 1 to 7As shown, during use, the oral surgery patient is under general anesthesia. After the tracheal intubation is inserted, this device is placed inside the patient's oral cavity. Since this device is soft in texture and has a cavity 5 inside, use surgical forceps to pinch this device until it deforms, place the anti-detachment wing 4 at the patient's larynx and then release the surgical forceps. Stretch out the anti-detachment wing 4, and clamp this device at the patient's larynx. Then gently press the handle 1 to make the mucosal fitting part 2 fit with the oral mucosa. Since the mucosal fitting part 2 has a decreasing thickness from the inside out, the edge is more likely to fit with the patient's oral mucosa and has a good degree of fit. Then perform oral surgery on the patient. At this time, the foreign bodies generated will be blocked outside the larynx by the mucosal fitting part 2. When the surgery is over, clean the oral cavity. After the cleaning is completed, gently pry the edge of the mucosal fitting part 2 to make the mucosal fitting part 2 separate from the cavity mucosa. Then gently pull the handle 1 to take out the device from the cavity. Since this device is soft in texture, when pulling the handle 1, the anti-detachment wing 4 deforms under the extrusion of the larynx, and it is very easy to take out this device from the larynx.
