Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary air pillow suitable for endotracheal intubation. Background Technology

[0002] Endotracheal intubation, a common and important clinical procedure, is widely used in pre-hospital emergency care, general anesthesia, and cardiopulmonary resuscitation. The primary purpose of endotracheal intubation is to ensure a patent airway and provide artificial ventilation or respiratory support; therefore, its success directly impacts patient safety. The success rate of endotracheal intubation is closely related to the number of complications during the procedure, the skill of the operator, and the selection of relevant equipment.

[0003] During endotracheal intubation, adequate exposure of the glottis is a prerequisite for successful intubation. By fully exposing the glottis with a laryngoscope, the operator can accurately insert the endotracheal tube into the trachea with the aid of direct vision or video laryngoscope, thereby ensuring airway patency.

[0004] However, in clinical practice, difficulty in exposing the glottis often becomes a significant obstacle to successful endotracheal intubation. Currently, traditional endotracheal intubation techniques face the following technical problems:

[0005] 1. Insufficient exposure of the glottis: When traditional laryngoscope blades are inserted into the oropharynx, the glottis is often not effectively exposed due to its high position. In this case, the operator is often forced to use a blind insertion method, that is, to shape the endotracheal tube with the aid of a stylet and insert it blindly, which greatly reduces the success rate of intubation.

[0006] 2. High operational risk: When the glottis is too high and the laryngoscope blade is not fully exposed, the medical operator may resort to force or repeated operations because they cannot see the tube. This not only causes great discomfort and pain to the patient during intubation, but may also cause traumatic damage such as edema and bleeding of the pharyngeal mucosa.

[0007] 3. Operational complexity: Insufficient glottic exposure directly leads to prolonged endotracheal intubation time, reduces the success rate of intubation, and increases the technical difficulty of the procedure. In this case, the medical operator needs to expend more effort and skill to complete the intubation.

[0008] In summary, existing endotracheal intubation techniques suffer from multiple limitations, including insufficient glottic exposure, high operational risks, technical complexity, and poor patient experience. Therefore, there is an urgent need for an effective endotracheal intubation technique that can address these issues, thereby improving intubation success rates, reducing operational risks, and enhancing patient experience. Utility Model Content

[0009] To address the shortcomings of existing technologies, the purpose of this invention is to propose an auxiliary air cushion suitable for endotracheal intubation. With the shoulder cushion, the first air cuff can be inflated to allow for placement in the classic laryngoscope position during intubation; with the head and neck cushions, the second air cuff can be inflated to allow for placement in the flower-smelling position during intubation. These two intubation positions solve the problems of insufficient glottal exposure and high operational difficulty.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An auxiliary air pillow suitable for endotracheal intubation includes a shoulder pillow, a neck pillow detachably connected to one side of the shoulder pillow, and a head pillow connected to the side of the neck pillow away from the shoulder pillow. The head pillow is cylindrical, and the neck pillow is sloping. The higher end of the neck pillow is connected to the head pillow, and the lower end of the neck pillow is connected to the shoulder pillow.

[0012] The shoulder cushion is equipped with a first airbag, and the neck cushion and head cushion are connected to a second airbag. The first airbag is connected to a first air tube, and the second airbag is connected to a second air tube. The other ends of the first and second air tubes are connected to an inflation tube via a T-junction, and the other end of the inflation tube is connected to an air pump.

[0013] Preferably, a first valve is installed on the first air pipe, and a second valve is installed on the second air pipe.

[0014] Preferably, the first airbag is an ellipsoidal balloon, and the second airbag includes multiple elliptical cylindrical airbags and multiple right-angled trapezoidal airbags. The elliptical cylindrical airbags are vertically arranged on both sides of the head cushion, and the multiple right-angled trapezoidal airbags are arranged in the neck cushion and the head cushion. The sloping sides of the right-angled trapezoidal airbags are located inside the neck cushion. The multiple elliptical cylindrical airbags and right-angled trapezoidal airbags are connected by a connecting tube, and the air outlet of the second air tube is connected to one of the elliptical cylindrical airbags.

[0015] Preferably, the shoulder cushion has a first hard plastic protective plate at the bottom and the outside, and the neck cushion and the head cushion have a second hard plastic protective plate at the outside and the bottom after they are connected.

[0016] Preferably, the shoulder pillow, neck pillow, and head pillow are all latex pillows.

[0017] Preferably, the air pump is a foot-operated air pump.

[0018] Preferably, the shoulder pad and the neck pad are detachably connected by a first hard plastic guard plate and a second hard plastic guard plate. The first hard plastic guard plate of the shoulder pad near the neck pad has a protrusion, and the second hard plastic guard plate of the neck pad near the shoulder pad has a groove. After the protrusion and the groove are slidably connected, convex plugs are installed at both ends of the groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The auxiliary air pillow of this utility model has two modes of use. First, by setting a first airbag in the shoulder cushion, when in use, the patient lies down with their shoulder resting on the shoulder cushion. At this time, the valve core of the second valve is turned to the air inlet, and the second trachea is blocked. The valve core of the first valve is turned to the bypass port, and the bypass port is blocked, connecting the air inlet and the working port. The air pump is turned on, and the first airbag is inflated through the air inlet tube. After inflation, it supports the patient's shoulder, making it convenient for intubation. When the first valve core is turned to the working port, the working port is blocked to prevent deflation, so that the patient is positioned in the classic laryngoscope position for intubation, which is convenient for tracheal intubation. Second, by setting a second airbag in the head cushion and neck cushion, when in use, the patient lies down with their shoulder resting on the shoulder cushion. The patient lies down with their head and neck resting on a headrest and neck support. Turn the first valve to the inlet, blocking the first trachea. Turn the second valve to the bypass port, blocking the bypass and connecting the inlet and working port. Turn on the inflation pump to inflate the second cuff through the inflation tube. After inflation, support the patient's neck and head, then turn the second valve (511) to the working port, blocking it to prevent deflation. This positions the patient in the olfactory position for intubation. Both methods ensure full exposure of the glottis, avoiding insufficient exposure and blind intubation that could lead to complications and throat injury, significantly improving the success rate of intubation.

[0021] (2) The first and second hard plastic protective plates of this utility model have limiting and shaping functions. When in use, they can prevent the airbag from deviating and collapsing when it is inflated. When not in use, they can be deformed for easy storage and can also improve the comfort of the auxiliary pillow. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figures 1-4 As shown, an auxiliary air pillow suitable for endotracheal intubation includes a shoulder pillow 100, a neck pillow 200 detachably connected to one side of the shoulder pillow 100, and a head pillow 300 connected to the side of the neck pillow 200 away from the shoulder pillow 100. The head pillow 300 is cylindrical, and the neck pillow 200 is sloping. The higher end of the neck pillow 200 is connected to the head pillow 300, and the lower end of the neck pillow 200 is connected to the shoulder pillow 100.

[0030] The shoulder cushion 100 is equipped with a first airbag 400, and the neck cushion 200 and head cushion 300 are connected to a second airbag 500. The first airbag 400 is connected to a first air tube 410, and the second airbag 500 is connected to a second air tube 510. The other end of the first air tube 410 and the second air tube 510 is connected to an inflation tube 600 through a T-junction, and the other end of the inflation tube 600 is connected to an air pump 700.

[0031] The air pump 700 is used to inflate the first airbag 400 and the second airbag 500. The inflated first airbag 400 can support the shoulder cushion 100, and the inflated second airbag 500 can support the head cushion 300 and the neck cushion 200. The head cushion 300 is cylindrical to better support the head, and the neck cushion 200 is sloping to better fit the neck.

[0032] It should be noted that the upper part of the cylindrical head cushion 300 can be set as a ramp, and the high part of the ramp is connected to the high part of the shoulder cushion 100, so that the patient's neck and head are connected at the highest position, which can better expose the glottis.

[0033] In this embodiment, a first valve 411 is installed on the first air pipe 410, and a second valve 511 is installed on the second air pipe 510.

[0034] Both the first valve 411 and the second valve 511 can be three-way valves. It should be noted that the three-way valve has an inlet, a working port, and a bypass port. During installation, the inlet and working port are connected to the trachea, with the inlet in the valve's inlet direction and the working port in the valve's outlet direction. When inflating the first airbag 400, rotate the valve core of the second valve 511 to the inlet position, blocking the second trachea 510. At this time, rotate the valve core of the first valve 411 to the bypass port, blocking the bypass port and connecting the inlet and working port. Turn on the inflation pump 700, and the first airbag 400 can be inflated through the inflation tube 600. After inflation, support the patient's shoulder to facilitate intubation. When the first valve 411 is turned to the working port, the working port is blocked, preventing gas leakage from the first airbag 400. After the patient examination or intubation is completed, the valve core of the first valve 411 is turned to the air inlet. At this time, the working port and the bypass port are connected, and the gas in the first airbag 400 is discharged through the bypass port, achieving the effect of deflation. When it is necessary to inflate the second airbag 500, the valve core of the first valve 411 is turned to the air inlet, and the second airbag 500 can be inflated according to the above operation, achieving the effect of independent control. Moreover, it can perfectly inflate, deflate, and preserve gas, with good performance.

[0035] In this embodiment, the first airbag 400 is an ellipsoidal balloon, and the second airbag 500 includes multiple elliptical cylindrical airbags 520 and multiple right-angled trapezoidal airbags 530. The elliptical cylindrical airbags 520 are vertically arranged on both sides of the head cushion 300, and the multiple right-angled trapezoidal airbags 530 are all arranged in the neck cushion 200 and the head cushion 300. The sloping sides of the right-angled trapezoidal airbags 530 are located inside the neck cushion 200. The multiple elliptical cylindrical airbags 520 and the right-angled trapezoidal airbags 530 are connected by a connecting pipe 540, and the air outlet of the second air pipe 510 is connected to one of the elliptical cylindrical airbags 520.

[0036] Multiple elliptical cylindrical airbags 520 and multiple right-angled trapezoidal airbags 530 fill the neck cushion 200 and head cushion 300, providing support. The elliptical cylindrical airbags 520 on both sides of the head cushion 300 can better fit the inner wall of the cylindrical head cushion 300. The right-angled trapezoidal airbags 530 are elongated and extend from the neck cushion 200 to the head cushion 300. When inflated, the head and neck can inflate simultaneously, making it more comfortable for the patient and improving the effect. The airbags are connected in pairs through the connecting tubes 540 to achieve the effect of simultaneous inflation.

[0037] In this embodiment, the shoulder cushion 100 is provided with a first hard plastic protective plate 110 at the bottom and the outside, and the neck cushion 200 and the head cushion 300 are provided with a second hard plastic protective plate 120 at the outside and the bottom after they are connected.

[0038] The first hard plastic protective plate 110 and the second hard plastic protective plate 120 have a limiting and shaping function. When in use, they can prevent the airbag from deviating and collapsing during inflation, and ensure the support effect of the shoulder pad 100, neck pad 200 and head pad 300.

[0039] It should be noted that the hard plastic backing is fixedly bonded to the cushion.

[0040] In this embodiment, the shoulder pillow 100, neck pillow 200, and head pillow 300 are all latex pillows.

[0041] Latex pillows are softer and have a resilient function, making them more comfortable to use.

[0042] In this embodiment, the air pump 700 is a foot-operated air pump.

[0043] The foot-operated air pump allows doctors to perform selective operations.

[0044] In this embodiment, the shoulder cushion 100 and the neck cushion 200 are detachably connected by a first hard plastic guard plate 110 and a second hard plastic guard plate 120. The first hard plastic guard plate 110 of the shoulder cushion 100 near the neck cushion 200 is provided with a protrusion 111, and the second hard plastic guard plate 120 of the neck cushion 200 near the shoulder cushion 100 is provided with a groove 121. After the protrusion 111 and the groove 121 are slidably connected, convex plugs are installed at both ends of the groove 121.

[0045] When separate use is required, the convex plug can be removed from one end of the groove 121 and slid outward through the protrusion 111 to separate it from the groove 121; after use, the protrusion 111 can be slid into the groove 121 to achieve mating installation, and the convex plug can be used to fix it after mating installation.

[0046] The working principle of this utility model's auxiliary air pillow for endotracheal intubation is as follows:

[0047] There are two ways to use this device. First, remove the convex plug at one end and slide the protrusion 111 away from the groove 121 to separate the shoulder cushion 100 from the head cushion 300 and neck cushion 200. Second, for the classic laryngoscopy position, use the shoulder cushion 100. The patient lies down with their shoulder resting on the shoulder cushion 100. Turn the valve core of the second valve 511 to the air inlet, blocking the second trachea 510. Turn the valve core of the first valve 411 to the bypass port, blocking the bypass port and connecting the air inlet and working port. The air pump 700 inflates the first cuff 400 through the air tube 600. After inflation, it supports the patient's shoulders, facilitating intubation. The valve core of the first valve 411 is turned to the working port, which blocks the working port to prevent deflation, thus assuming the classic laryngoscopy position for intubation. This elevates the patient's shoulders, allowing the patient to open their mouth and fully expose the glottis, facilitating endotracheal intubation. Alternatively, the "flower-smelling position" can be used, with the patient lying down and using a head pillow 300 and a neck pillow 200. The patient's head is placed on... With the head resting on pillow 300 and the neck resting on pillow 200, turn the valve core of the first valve 411 to the air inlet, blocking the first air tube 410. Turn the valve core of the second valve 511 to the bypass port, blocking the bypass port and connecting the air inlet and working port. Turn on the air pump 700, and the second air bag 500 can be inflated through the air tube 600. After inflation, the patient's head rests on the head resting on pillow 300 and the neck rests on pillow 200. Turn the valve core of the second valve 511 to the working port, blocking the working port to prevent deflation. The patient is positioned in the olfactory position for intubation, and the glottis is fully exposed when the patient opens their mouth. Both methods of use ensure full exposure of the glottis, avoiding the problem of insufficient exposure and blind insertion by the operator, which can cause discomfort to the patient. This greatly improves the success rate of intubation. After use, the valve core is rotated to the air inlet, and both the first airbag 400 and the second airbag 500 are deflated. The groove 121 and the protrusion 111 can then be slidably connected and secured by the convex plug for easy storage.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
