Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a malleable auxiliary ventilation mask for endoscopic examination. Background Technology

[0002] Endoscopy is a common medical diagnostic and treatment method. It involves using an endoscope to examine, diagnose, or treat diseases in cavities that connect the patient to the outside world. Common types include digestive endoscopy and respiratory endoscopy. With the increasing popularity of comfortable medical care and to ensure safer endoscopic procedures, anesthesia, commonly known as "painless," is often administered to patients in clinical practice. This includes painless gastroscopy, colonoscopy, and bronchoscopy. However, after the administration of anesthesia, coupled with oral endoscopic procedures, patients often experience respiratory depression and decreased blood oxygen saturation, which can lead to life-threatening complications in severe cases. In such situations, the procedure must be paused, the endoscope removed, and the patient given controlled ventilation via a mask by an anesthesiologist until the patient's condition improves before the procedure can continue. This not only affects patient safety but also significantly reduces the efficiency of endoscopic examinations.

[0003] A malleable assisted ventilation mask is a specially designed mask used to provide assisted ventilation during endoscopic procedures.

[0004] Existing ventilation masks require the endoscope to be inserted into the oral cavity through a physical leak-proof device via the endoscope port on the mask. The endoscope lens inevitably rubs against this device; however, endoscope lenses are very delicate, and friction can easily cause scratches, affecting clarity and thus impacting observation, potentially leading to missed or misdiagnosed diagnoses. During endoscopic examinations, operators often need to repeatedly advance, retreat, and rotate the endoscope to examine different areas. However, the existing leak-proof devices on the masks are prone to leakage during this process, failing to guarantee effective oxygen and air supply to the patient. Current solutions involve tightening the mask's fasteners to artificially increase the mask's closure to the patient's face, while simultaneously increasing the pressure on the ventilator used for assisted ventilation.

[0005] However, this approach can lead to some adverse consequences:

[0006] 1. Tightening the fastening buckles will increase the pressure of the mask on the face. Endoscopic procedures may cause the mask to shift, potentially leading to pressure on facial tissues and organs. For example, prolonged pressure on the eyes could result in blindness. Furthermore, in clinical practice, due to significant differences in facial features among patients, tightening the fastening buckles to increase pressure has little effect on ensuring the mask's closure.

[0007] 2. Increasing the ventilation pressure on the assisted ventilation machine can lead to poor respiratory coordination and low patient comfort for patients undergoing endoscopy without the use of muscle relaxants. Most importantly, higher ventilation pressure may force excessive air into the patient's stomach, potentially causing postoperative nausea and vomiting.

[0008] Therefore, there is a need to provide a malleable auxiliary ventilation mask for endoscopic examinations to prevent air leakage from the connection between the endoscope and the ventilation mask during the examination, which would affect the ventilation efficiency. Summary of the Invention

[0009] This invention provides a malleable auxiliary ventilation mask for endoscopic examinations to solve the problems in the prior art.

[0010] The present invention employs the following technical solution: a malleable auxiliary ventilation mask for endoscopic examination, comprising a mask body, an endoscope hole on the front of the mask body, and an insertion tube sleeve for inserting an endoscope connected to the endoscope hole; the bottom of the insertion tube sleeve is connected to the mask body, and the top of the insertion tube sleeve is connected to a one-way valve sleeve; a suffocating airbag that can contract or expand is provided inside the insertion tube sleeve, the suffocating airbag can seal the gap between the endoscope and the insertion tube sleeve, and a conduit for controlling the ventilation of the suffocating airbag is provided on the suffocating airbag, the conduit being connected to the suffocating airbag and extending to the outside of the mask body; the mask body is provided with an oxygen supply tube and a ring-shaped memory foam.

[0011] Furthermore, the one-way valve sleeve is provided with a plurality of one-way valves, which are evenly spaced and arranged circumferentially on the one-way valve sleeve. The outer circumference of the one-way valve sleeve has crease grooves for folding the valves, and these crease grooves are slightly lower than the outer circumference of the one-way valve sleeve. A through groove is located in the middle of the one-way valve sleeve. This protects the endoscope lens and alleviates the endoscopist's concerns about damage to the endoscope lens.

[0012] Furthermore, the one-way valve has a triangular structure, and adjacent one-way valves are in a mutually closed and sealed state when closed. The one-way valve can be extended and retracted to accommodate endoscopes of different diameters for protection.

[0013] Furthermore, the sealing airbag is provided with a spring coil, the outer wall of which is connected to the inner wall of the sealing airbag. The spring coil can contract or expand within the sealing airbag. A tubular hole is provided at the middle position between the spring coil and the sealing airbag. A one-way valve is provided on the conduit of the sealing airbag.

[0014] Furthermore, the one-way valve includes a connecting pipe that communicates with a connecting airbag. A conical end cap is located inside the connecting pipe, and a moving rod is located at the rear end of the conical end cap. A return spring is located on the conical end cap, and a connecting bracket connected to the inside of the connecting pipe is located on the return spring. A sealing block that seals against the conical end cap is located inside the connecting pipe, and a connecting pipe is provided on the connecting pipe. This design can seal gaps created during endoscopic operations, preventing gas leakage during endoscope rotation and avoiding postoperative discomfort to the patient due to blindly increasing the assisted ventilation pressure.

[0015] Furthermore, a connecting airbag is provided between the conduit and the one-way valve; the connecting airbag allows observation of whether the sealing airbag is leaking.

[0016] Furthermore, the oxygen supply tube is a telescopic single-threaded tube, and the mask body is provided with an oxygen hole located below the endoscope hole on the front of the mask body. The oxygen supply tube is connected to the oxygen hole.

[0017] Furthermore, the mask body is also equipped with a fixing elastic cord, and the fixing elastic cord has a mask fixing buckle. The mask body can be fixed to the patient by the mask fixing buckle, so that it is not easy to fall off during the operation of the endoscope, and a closed oxygen inhalation space is provided.

[0018] Furthermore, the ring-shaped memory foam is located on the bottom surface of the mask body, and the ring-shaped memory foam is consistent with the shape of the mask body. The ring-shaped memory foam better fits the patient's face shape and will not cause gas leakage during endoscopic examinations, thus not affecting the patient's breathing.

[0019] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0020] This invention features a specially designed, moldable, skin-friendly memory foam protective pad suitable for various face shapes, as well as an endoscope size-adaptable protective kit. This kit not only fits different face shapes but also ensures airtightness while reducing damage to patients caused by mask displacement. It also features a lens-free leak-proof protective kit to ensure uninterrupted examination procedures while assisting patient ventilation and preventing hypoxia.

[0021] At the same time, taking into account the concerns of endoscopists about the damage to the delicate endoscope lens caused by the mask in the past, the flexible mask has been specially designed with a non-lens contact triple leak-proof protection structure, which greatly improves the problem of air leakage during operation and avoids postoperative discomfort to patients caused by blindly increasing the assisted ventilation pressure.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Reference Figures 1 to 14 As shown, this embodiment of the invention provides a malleable auxiliary ventilation mask for endoscopic examination, including a mask body 1. The front of the mask body 1 is provided with an endoscope hole 11, and an insertion tube sleeve 12 for inserting an endoscope is connected to the endoscope hole 11. The bottom of the insertion tube sleeve 12 is connected to the mask body 1, and the top of the insertion tube sleeve 12 is connected to a one-way valve sleeve 2. The insertion tube sleeve 12 is provided with a sealing airbag 3 that can be contracted or expanded. The sealing airbag can seal the gap between the endoscope and the insertion tube sleeve 12. The sealing airbag 3 is provided with a conduit 4 for controlling the ventilation of the sealing airbag 3. The conduit 4 is connected to the sealing airbag 3 and extends to the outside of the mask body 1. The mask body 1 is provided with an oxygen supply tube 5 and a ring-shaped memory foam 6.

[0042] When in use, the mask body 1 is fixed to the patient's face with two elastic cords 7. The ring-shaped memory foam 6 makes the mask body 1 fit the patient's face better, and will not cause oxygen gas to leak out during ventilation, providing the first layer of protection against gas leakage.

[0043] During an endoscopic examination, the endoscope is inserted into the mask body 1 through the one-way valve sleeve 2 and the insertion tube sleeve 12. During the insertion process, several one-way valves 21 are in a vertical position, which will not damage the lens of the endoscope. After the movement is completed, the several one-way valves 21 in the vertical position are rotated to a horizontal position to protect the endoscope.

[0044] Then, the syringe is connected to the connecting tube 39 to inflate the occlusion airbag 3, causing it to expand. The expanded occlusion airbag 3 can seal and fill the gap between the endoscope and the insertion tube sleeve 12, preventing gas leakage from the endoscope and the patient from being unable to breathe normally after ventilation in the mask body 1. The occlusion airbag 3 can achieve double leakage protection, ensuring the safety of the patient.

[0045] After use, the sealing airbag 3 can be removed from the inlet sleeve 12, and the sealing airbag 3 can be cleaned and disinfected to facilitate the next use of the sealing airbag 3.

[0046] Specifically, the one-way valve sleeve 2 is provided with a plurality of one-way flaps 21, which are arranged in a circular pattern at equal intervals on the one-way valve sleeve 2. The outer ring plane of the one-way valve sleeve 2 is provided with fold grooves 22 for the one-way flaps 21 to be folded. The fold grooves 22 are slightly lower than the outer ring plane of the one-way valve sleeve 2. The one-way valve sleeve 2 is provided with a through groove 23 in the middle position. The one-way flaps 21 are triangular in structure, and adjacent one-way flaps 21 are in a closed state of mutual tightness and sealing.

[0047] The one-way valve 21 is a sponge pad that can be squeezed. When it is in a horizontal state, the mutual compression can make the two adjacent one-way valves 21 in a sealed state. When protecting endoscopes of different diameters, the one-way valve 21 of the sponge pad can be stretched to adapt to the protection of endoscopes of different diameters.

[0048] In this embodiment,

[0049] Before endoscope insertion (see reference) Figure 7 As shown): Several one-way valves 21 are in a vertical state, several one-way valves 21 are folded upward around the fold groove 22, and several one-way valves 21 are in an open state. The diameter of the passage through the groove 23 will become larger, which facilitates the entry of the endoscope lens and will not cause damage to the lens when it enters.

[0050] After endoscope insertion (see reference) Figure 6 (As shown): Several one-way valves 21 are pulled downwards, so that the one-way valves 21 in the vertical position are rotated to the horizontal position, which protects the endoscope rod and can also prevent gas leakage.

[0051] After the endoscopic examination is completed (see reference) Figure 7As shown): When medical staff move several one-way valves 21 from a horizontal position to a vertical position, the diameter of the through groove 23 will increase, and the endoscope lens and rod will easily pass through the through groove 23. When the endoscope moves upward from the mask body 1, it will not damage the lens, will not rub the lens, will not affect the clarity of subsequent endoscopic observation, and will not cause serious consequences such as missed diagnosis or misdiagnosis.

[0052] Specifically, the sealing airbag 3 is provided with a spring coil 31, the outer wall of the spring coil 31 is connected to the inner wall of the sealing airbag 3, the spring coil 31 can contract or expand within the sealing airbag 3, a tubular hole 32 is provided at the middle position of the spring coil 31 and the sealing airbag 3, and a one-way valve 30 is provided on the conduit of the sealing airbag 3; the one-way valve 30 includes a connecting pipe 33, the connecting pipe 33 is connected to the connecting airbag 8, a conical end cap 34 is provided inside the connecting pipe 33, a moving rod 35 is provided at the rear end of the conical end cap 34, a return spring 36 is provided on the conical end cap 34, a connecting bracket 37 connected to the inside of the connecting pipe 33 is provided on the return spring 36, a sealing block 38 is provided inside the connecting pipe 33 that seals against the conical end cap 34, and a connecting pipe 39 is provided on the connecting pipe 33.

[0053] In this embodiment, the sealing airbag 3 can be contracted and expanded by the contraction and expansion of the spring coil 31, thereby sealing the gap between the endoscope rod and the insertion tube sleeve 12, preventing gas leakage when ventilating the face shield body 1, which would affect the patient's use. When the endoscope rod is passed through the tubular hole 32, the diameter of the tubular hole 32 is much larger than the diameter of the endoscope lens when the spring coil 31 is in the contracted state, which facilitates the inward delivery of the lens and will not cause damage to the lens.

[0054] When the spring coil 31 is in the expanded state (refer to...) Figure 4 and Figure 9 (As shown): At this time, the sealing airbag 3 needs to be inflated to expand the spring coil 31. The head of the syringe is inserted into the connecting tube 39, and gas is injected into it through the syringe. The gas will cause the conical end cap 34 to retract back through the moving rod 35 and drive the return spring 36 to separate the conical end cap 34 from the sealing block 38. At this time, a gap will be formed between the conical end cap 34 and the sealing block 38. The gas injected into it through the syringe will be delivered into the sealing airbag 3. After the air is injected into the syringe, the presence of the return spring 36 causes the conical end cap 34 to abut against the sealing block 38, forming a seal between the conical end cap 34 and the sealing block 38 to prevent gas from leaking out.

[0055] When spring coil 31 is in the contracted state (refer to...) Figure 5 andFigure 8 (As shown): At this point, the gas in the sealing airbag 3 needs to be expelled. This can be done by pressing the tip of the syringe against the conical end cap 34 or by pressing the deflation tool against the conical end cap 34. Moving the conical end cap 34 inward will disengage it from the sealing block 38, thus expelling the gas in the sealing airbag 3. At this time, the spring coil 31 is also in a contracted state. After contraction, the diameter of the tubular hole 32 will also increase, which will help to move the endoscope lens outward without causing damage to the lens or friction affecting its use.

[0056] Specifically, a connecting airbag 8 is provided between the conduit 4 and the one-way valve 30;

[0057] In this embodiment, when the occlusion airbag 3 is inflated or deflated, the existing syringe is connected to the connecting tube 39. During the inflation and occlusion process of the occlusion airbag 3, the amount of gas injected into the occlusion airbag 3 can be recorded by the scale marked on the syringe. This ensures that during the expansion process of the occlusion airbag 3 and the spring coil 31, the amount of gas in the occlusion airbag 3 will not be too much, causing damage to the occlusion airbag 3, nor will it be too little, resulting in a gap between the endoscope and the occlusion airbag 3 and causing air leakage.

[0058] A connecting airbag 8 is provided between the one-way valve 30 and the conduit 4. When inflated, the connecting airbag 8 is also inflated, and the gas is delivered to the sealing airbag 3 through the conduit 4. When the gas in the sealing airbag 3 is saturated and the spring coil 31 is in an expanded state, the connecting airbag 3 is also filled with gas. The gas in the connecting airbag 8 and the sealing airbag 3 are connected together. The purpose of designing the connecting airbag 8 is to be able to determine whether the sealing airbag 3 is leaking by observing the connecting airbag 8 when sealing the gap, which is convenient for observation. Moreover, the conduit 4 is located on the side of the mask body 1, which also facilitates the operation of inflating the sealing airbag 3.

[0059] Specifically, the oxygen supply tube 5 is a telescopic single-threaded tube, and the mask body 1 is provided with an oxygen hole. The oxygen hole is located below the endoscope hole 11 on the front of the mask body 1, and the oxygen supply tube 5 is connected to the oxygen hole.

[0060] In this embodiment, the telescopic single-threaded tube is telescopic, with one end connected to the oxygen supply port on the mask body 1 and the other end connected to the oxygen supply machine. The telescopic single-threaded tube can rotate 360 ​​degrees, so that it does not affect the operation of the endoscopic examiner when using the mask body 1. The telescopic single-threaded tube is also because the breathing loop connected to the breathing device is generally large and occupies the space on the side of the patient's head, which can easily affect the operation of the endoscopic operator.

[0061] Specifically, the mask body 1 is also provided with a fixing elastic cord 7, and the fixing elastic cord 7 is provided with a mask fixing buckle 71;

[0062] In this embodiment, the mask body 1 is placed over the patient's face during use, and two fixing elastic ropes 7 are passed through the patient's head. The mask body 1 can be fixed to the patient by the mask fixing buckle 71, so that it is not easy to fall off during the operation of the endoscope, and a closed oxygen inhalation space is provided.

[0063] Specifically, the annular memory foam 6 is located on the bottom surface of the mask body 1, and the annular memory foam 6 has the same shape as the mask body 1;

[0064] In this embodiment, the ring-shaped memory foam 6 can adaptively adjust and shape according to the patient's body shape and temperature, providing more personalized support and comfort. When some patients are in a coma for a long time or are malnourished, their cheekbones may protrude and their cheeks may become sunken. The ring-shaped memory foam 6 can better fit and conform to the patient's face shape. When there is oxygen with a certain pressure in the inner cylinder of the mask body 1, it will not cause gas leakage and will not affect the patient's breathing during endoscopic examinations.

[0065] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
