Description

Technical Field

[0001] This utility model relates to a medical auxiliary device, and more particularly to an adjustable-length painless gastroscopy device for gastroscopy. Background Technology

[0002] In clinical practice, during painless gastroscopy, a gastroscopy mouth block is often used to open the patient's mouth. The purpose of the mouth block is to keep the patient's mouth open and prevent the patient from biting the endoscope with their incisors. Currently, the traditional gastroscopy mouth block used clinically is made of white plastic and is generally oval-shaped. Before the procedure, medical staff place the mouth block between the patient's upper and lower incisors to open the mouth and protect the endoscopic catheter.

[0003] Before performing a painless gastroscopy, medical staff need to administer intravenous general anesthesia to the patient. During the anesthesia, the patient loses control of their body, and the base of the tongue may fall back, obstructing the upper airway and leading to hypoxia and a risk of suffocation. In such cases, an oropharyngeal airway can be placed to prevent the tongue from falling back, thereby increasing the space between the tongue and the pharyngeal wall and maintaining an open upper airway. However, the length of the oropharyngeal airway that can be accommodated varies from patient to patient. Therefore, medical staff need to select the appropriate oropharyngeal airway based on the actual needs. An excessively long oropharyngeal airway can repeatedly induce vomiting after placement, affecting the surgical process, while an excessively short oropharyngeal airway cannot pass through the base of the tongue and thus cannot open the airway.

[0004] Current technology often combines the endoscope mouthpiece and oropharyngeal airway, forming a combined device that can effectively open the patient's mouth while avoiding airway obstruction. However, existing combined devices are simply a combination of the two and cannot adjust the depth at which the part of the device that functions as the oropharyngeal airway is inserted into the patient's throat. This makes it difficult to guarantee the patient's comfort, leading to potential obstructions during the examination. Furthermore, medical staff often need to purchase combined devices of various lengths for different treatment needs, resulting in high costs. Utility Model Content

[0005] The purpose of this invention is to provide a painless gastroscopy device for clinical gastroscopy surgery that can adjust the length of the oropharyngeal airway inserted into the patient's oral cavity.

[0006] To achieve the above objectives, this utility model provides an adjustable-length painless gastroscopy device, which includes a mouth pad and an oropharyngeal airway that is sleeved and movably engaged with the mouth pad.

[0007] The mouth pad includes a baffle and a fixing sleeve disposed at the center of the baffle. The baffle has through holes on both sides for connecting the strap, and the bottom of the fixing sleeve is provided with a first adjustment device for movable connection with the oropharyngeal airway.

[0008] The oropharyngeal airway includes a movable bite block disposed at the front end of the oropharyngeal airway and a pharyngeal flap for insertion into the upper respiratory tract to facilitate gastroscopy guidance and prevent patient asphyxiation. The movable bite block and the pharyngeal flap are connected. The movable bite block is provided with a first oxygen supply channel and a second adjustment device for oxygen supply. The first oxygen supply channel is disposed inside the movable bite block, and the second adjustment device is disposed outside the movable bite block. The movable bite block is movably engaged with the first adjustment device of the fixed sleeve through the second adjustment device to change the depth of the pharyngeal flap inserted into the patient's upper respiratory tract. The pharyngeal flap includes a pharyngeal flap body and a second oxygen supply channel disposed on the pharyngeal flap body. The second oxygen supply channel and the first oxygen supply channel are directly connected.

[0009] Compared to existing technologies, this invention innovatively introduces an adjustable-length painless gastroscopy device to meet the diverse needs of patients undergoing gastroscopy. Before the gastroscopy, medical staff utilize this device: first, they observe the patient's condition; second, considering factors such as the patient's age and oral cavity condition, they attach the oropharyngeal airway to the mouth pad; then, through the interlocking of the first and second adjustment devices, they change the length of the oropharyngeal airway extending beyond the mouth pad, thereby adjusting the depth of the pharyngeal flexure plate inserted into the patient's upper respiratory tract. This allows the patient to adapt to the device, increasing patient comfort and improving the smoothness of the gastroscopy procedure. Furthermore, the medical staff no longer needs to purchase multiple sizes of oropharyngeal airways and mouth pads, further reducing medical costs. In addition, this invention solves the problem that it is impossible to place an oropharyngeal airway to open the airway at the same time as placing a mouth pad during painless gastroscopy. It ensures airway opening, avoids tongue retraction or airway obstruction that could lead to hypoxia / hypoxia in patients, and at the same time ensures that the patient's mouth is effectively open, protecting the gastroscope from damage or breakage due to the patient's biting.

[0010] As can be seen from the above, throughout the entire use of this utility model, the adjustable-length painless gastroscopy device allows medical staff to make appropriate adjustments for different oral conditions, promoting the smooth progress of the surgery and enhancing the patient's experience during the gastroscopy examination, improving comfort and reflecting humanistic care. At the same time, this utility model effectively provides a solution to the problem of different lengths of oropharyngeal airways required for different patients, avoiding the need to purchase multiple types of oropharyngeal airways and saving consumable costs.

[0011] Optionally, the first adjusting device comprises a plurality of consecutive positioning holes, and the second adjusting device comprises a positioning protrusion for engaging with the positioning holes. The positioning protrusion can engage with one of the consecutive positioning holes, and by engaging the positioning protrusion with different positioning holes, the length of the oropharyngeal airway extending from the mouth pad and the depth of insertion into the patient's oral cavity can be adjusted.

[0012] Optionally, the fixed sleeve and the movable dental pad have the same rounded triangular cross-section, and the movable dental pad is fitted into the fixed sleeve. The identical cross-section of the fixed sleeve and the movable dental pad allows the movable dental pad to fit into the fixed sleeve, thereby achieving length adjustment. The triangular and rounded corner design conforms to human biting habits and prevents the edges from scratching the oral cavity, causing wounds and serious infections.

[0013] Optionally, one end of the first oxygen supply channel is provided with a pagoda connector for connecting an oxygen supply device. The oxygen supply device is connected to the oxygen supply channel via a pipe. The pagoda connector can connect to pipes of various diameters, offering flexible and adaptable connections. When the oxygen supply device is connected to the first oxygen supply channel using a flexible pipe, the pagoda connector increases friction to prevent the flexible pipe from falling off and affecting the inspection process.

[0014] Optionally, the pharyngeal flap has a C-shaped curved structure adapted to the human pharynx. This adaptation allows the pharyngeal flap to fit snugly against the patient's throat, providing more precise guidance for the endoscope during gastroscopy and improving oxygen supply efficiency.

[0015] Optionally, the second oxygen supply channel and the pharyngeal plate are integrally formed, and both the first oxygen supply channel and the second oxygen supply channel have a cylindrical structure.

[0016] Optionally, the present invention further includes an anti-slip ring with the same longitudinal section as the fixed sleeve. The anti-slip ring is disposed between the movable dental pad and the pharyngeal flexure plate, and the diameter of the anti-slip ring is not less than the diameter of the fixed sleeve. The anti-slip ring is used to limit the length of the movable dental pad when it is pushed outward, preventing the oropharyngeal airway from being pushed outward by the patient during the examination.

[0023] Please see Figures 1 to 4 As shown, the adjustable-length painless gastroscopy device of this invention provides a device that can change the insertion depth into the oral cavity to enhance patient comfort, improve the smoothness of gastroscopy operation, and save costs during gastroscopy.

[0024] The adjustable-length painless gastroscopy device of this utility model includes a mouth pad 1 and an oropharyngeal airway 2 that is sleeved and movably engaged with the mouth pad 1 at its front end. The mouth pad 1 includes a baffle 11 and a fixed sleeve 12 disposed at the center of the baffle 11. The oropharyngeal airway 2 includes a movable bite pad 21 disposed at the front end of the oropharyngeal airway 2 and a pharyngeal flexure plate 22 for insertion into the upper respiratory tract to guide the gastroscopy and prevent the patient from suffocating. The movable bite pad 21 and the pharyngeal flexure plate 22 are connected.

[0025] Specifically, in some embodiments, the baffle 11 has through holes 111 on both sides for connecting the strap, the bottom of the fixing sleeve 12 is provided with a first adjustment device 121 for movably connecting with the oropharyngeal airway 2, the movable bite pad 21 is provided with a first oxygen supply channel 211 for supplying oxygen and a second adjustment device 212, the first oxygen supply channel 211 is provided inside the movable bite pad 21, the second adjustment device 212 is provided outside the movable bite pad 21, the movable bite pad 21 is movably engaged with the first adjustment device 121 of the fixing sleeve 12 through the second adjustment device 212 to change the depth of the pharyngeal plate 22 inserted into the patient's upper respiratory tract, the pharyngeal plate 22 includes a pharyngeal plate body 221 and a second oxygen supply channel 222 provided on the pharyngeal plate body 221, the second oxygen supply channel 222 and the first oxygen supply channel 211 are directly connected.

[0026] See Figures 1 to 4 As shown, before the start of the gastroscopy, the medical staff uses this invention. First, the medical staff observes the condition of the patient being examined. Then, considering factors such as the patient's age and oral condition, the oropharyngeal airway 2 is fitted into the mouth pad 1. Subsequently, by the movable engagement between the first adjustment device 121 and the second adjustment device 212, the length of the oropharyngeal airway 2 extending out of the mouth pad 1 is changed, thereby adjusting the depth of the pharyngeal flexure plate 22 in the oropharyngeal airway 2 inserted into the patient's upper respiratory tract, so that the patient can adapt to this invention, in order to better carry out the gastroscopy.

[0027] In addition, this invention solves the problem that the oropharyngeal airway 2 cannot be placed at the same time as the mouth pad during painless gastroscopy, ensuring airway opening and avoiding posterior displacement of the tongue or airway obstruction that could lead to hypoxia / hypoxia in patients. At the same time, it ensures that the patient's mouth is effectively open, protecting the gastroscope from damage or breakage due to the patient's biting.

[0028] As can be seen from the above, throughout the entire use of this utility model, the adjustable-length painless gastroscopy device allows medical staff to make appropriate adjustments for different oral conditions, which helps to enhance the patient's experience during the gastroscopy process, improve comfort, and reflect humanistic care. At the same time, this utility model effectively provides a solution to the problem of different lengths of oropharyngeal airways 2 required for different patients, avoiding the need to purchase multiple types of oropharyngeal airways 2 and saving consumable costs.

[0029] Please see Figure 1 and Figure 3As shown, specifically, the first adjusting device 121 consists of several consecutive positioning holes, and the second adjusting device 212 is a positioning protrusion for engaging with the positioning holes. The positioning protrusion can engage with one of the consecutive positioning holes. During use, the oropharyngeal airway 2 is fitted into the mouth pad 1, and then the mouth pad 1 and the oropharyngeal airway 2 are combined through the engagement between the positioning protrusion and the positioning hole. By engaging the positioning protrusion with different positioning holes, the length of the oropharyngeal airway 2 extending out of the mouth pad 1 can be adjusted, thereby adjusting the depth of the oropharyngeal airway 2 inserted into the patient's oral cavity.

[0030] Please see Figure 2 As shown, in some embodiments, the fixed sleeve 12 and the movable dental pad 21 have the same rounded triangular cross-section, with the movable dental pad 21 fitted inside the fixed sleeve 12. The identical cross-section of the fixed sleeve 12 and the movable dental pad 21 allows the movable dental pad 21 to fit into the fixed sleeve 12, thereby achieving length adjustment. The triangular and rounded corner design conforms to human biting habits and prevents the edges from scratching the oral cavity, causing wounds and serious infections.

[0031] Please see Figures 1 to 4 As shown, in some embodiments, one end of the first oxygen supply channel 211 is provided with a pagoda connector 23 for connecting an oxygen supply device. The oxygen supply device is connected to the oxygen supply channel via a pipe, and the pagoda connector 23 can connect pipes of various diameters, offering flexible and adaptable connections. When the oxygen supply device is connected to the first oxygen supply channel 211 using a flexible pipe, the pagoda connector 23 increases friction, preventing the flexible pipe from falling off and thus affecting the inspection process.

[0032] Please see Figure 1 , Figure 3 and Figure 4 As shown, the pharyngeal convoluted plate 22 has a C-shaped curved structure adapted to the human pharynx. The pharyngeal convoluted plate 22, adapted to the pharynx, allows it to fit closely to the patient's throat, thereby providing more precise guidance for the inserted endoscope during gastroscopy, and ensuring more precise and direct oxygen supply, thus improving oxygen supply efficiency.

[0033] In some embodiments, the second oxygen supply channel 222 and the pharyngeal flexure plate 22 are integrally formed, and both the first oxygen supply channel 211 and the second oxygen supply channel 222 have a cylindrical structure. The integrally formed second oxygen supply channel 222 and pharyngeal flexure plate 22, compared to independently formed structures, reduce the risk of repeated collisions between the oxygen supply channel and the endoscope during gastroscopy, and also prevent the oxygen supply channel from dislodging, thus improving the safety of gastroscopy.

[0034] Please see Figure 1 , Figure 3 and Figure 4In some embodiments, the present invention further includes an anti-slip ring 24 with the same longitudinal section as the fixed sleeve 12. The anti-slip ring 24 is disposed between the removable dental pad 21 and the pharyngeal flexure plate 22, and the ring diameter of the anti-slip ring 24 is not less than the diameter of the fixed sleeve 12. The anti-slip ring 24 is used to limit the length of the removable dental pad 21 when it is pushed outward, preventing the oropharyngeal airway 2 from being pushed outward by the patient during the examination or from slipping out due to saliva adhesion.

[0035] Specifically, the adjustable-length painless gastroscopy device of this invention is preferably made of materials such as thermoplastic polyurethane, which is low in cost, stable, and has good chemical resistance and wear resistance.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Meanwhile, the above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
