Description

Technical Field

[0001] The invention relates to the field of tracheal intubation, and in particular to an auxiliary positioning device for emergency tracheal intubation. Background Art

[0002] Emergency endotracheal intubation is an emergency medical procedure designed to quickly establish an artificial airway to maintain the patient's respiratory function. When a patient is unable to breathe on his own due to respiratory failure, airway obstruction, cardiac arrest or surgical anesthesia, the doctor will insert a special endotracheal tube into the trachea through the mouth or nose to ensure that the airway is open and provide mechanical ventilation support.

[0003] The existing intubation procedure is to first use a ventilator on the patient, the purpose of which is to increase the patient's oxygen reserve and ensure that the patient can maintain adequate oxygen supply even if a brief apnea occurs during the intubation process. Then, move the items required for intubation (such as laryngoscope, endotracheal tube, guidewire, lubricant, fixing tape, etc.) to the bedside, and adjust the patient's position so that his head is tilted back and his oropharynx is in a straight line. Next, the operator holds the laryngoscope in his left hand, inserts it from the right corner of the patient's mouth, gently pushes the tongue away, and exposes the glottis; holds the endotracheal tube in his right hand, accurately inserts it into the glottis along the laryngoscope path, and after confirming that the tube has entered the trachea, connect the ventilator and fix the tube. Finally, by auscultating the breath sounds of both lungs and observing the rise and fall of the chest, confirm that the intubation position is correct and start mechanical ventilation.

[0004] However, the above steps are only applicable when the patient is in bed and when there are sufficient medical supplies. If the patient needs to be intubated in complex situations such as in the wild, the existing intubation technology cannot guarantee that the patient can be effectively intubated at a certain speed and safety, which further worsens the patient's condition.

DETAILED DESCRIPTION

[0032] The following combination Figures 1 to 10 Embodiments of the present invention are described in detail.

[0033] The embodiment of the present application discloses an auxiliary positioning device for emergency tracheal intubation, which explains that the present application is mainly used in scenes such as outdoor, so that medical staff can carry the medical equipment required for intubation and perform auxiliary intubation on patients on the spot. In terms of technical effect, the medical equipment required for intubation can be stored and protected by providing a protective box, which is convenient for medical staff to carry. The pillow assembly provided on the outside of the protective box can also enable the protective box to support the patient's head and fix the protective box at the same time. Furthermore, a positioning device for auxiliary clamping of the intubation is also provided inside the protective box to assist medical staff in intubation.

[0034] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a protection box 1, a curved surface 10, a pillow assembly 2, a cover plate 11 and a lifting handle 12. One side of the protection box 1 is a curved surface 10, and the inner wall of the curved surface 10 is provided with a pillow assembly 2 for assisting the patient's head to rest. One side of the protection box 1 is provided with a cover plate 11 in a hinged manner, and the outer side of the cover plate 11 corresponds to the upper end of the protection box 1, and one side of the cover plate 11 is provided with a lifting handle 12.

[0035] That is, when the patient needs to be intubated on the spot, the medical staff lifts the protection box 1 by pulling the handle 12 and moves it to the side of the patient, and then places the patient's head on the pillow assembly 2 to provide auxiliary support for the patient's head, which is convenient for the medical staff to perform the intubation operation, and then flips the cover 11 off the protection box 1, no longer sealing the protection box 1, and picks up the medical equipment in the protection box 1 to prepare for intubation of the patient.

[0036] Reference Figure 3 and Figure 4 As shown, the pillow assembly 2 is used to assist the patient's head to rest on it; specifically, the pillow assembly 2 includes an arc plate 20, a headrest 21, an arc frame 22, a support plate 23, a blocking plate 24 and a plug-in handle 25. The arc plate 20 is arranged on the inner wall of the arc surface 10, and a headrest 21 is arranged on the arc plate 20. The headrest 21 is made of a flexible material, and the shape of the headrest 21 corresponds to the arc plate 20. That is, the protection box 1 is first placed on the ground, and then the patient's head is lifted and placed on the headrest 21. Since the headrest 21 is made of a flexible material, it can cushion the patient's head and improve the comfort of the patient's head. At the same time, after the patient's head rests on the headrest 21, the arc plate 20 can also limit the protection box 1 to a certain extent, and limit the protection box 1 on the ground to prevent the protection box 1 from moving accidentally.

[0037] An arc frame 22 is detachably provided at the upper end of the arc plate 20, and the outer side of the arc frame 22 corresponds to the inner diameter of the arc surface 10, and a support plate 23 located at the upper end of the headrest 21 is provided on the inner wall of the arc frame 22, that is, medical equipment, such as an oxygen mask, can be placed inside the arc frame 22, and a separate placement space can prevent the oxygen mask from colliding with the outside and causing damage, and the oxygen mask is placed in the arc frame 22 and supported by the support plate 23 to prevent the oxygen mask from contacting the headrest 21; and a blocking plate 24 is slidably plugged into the opening at the upper end of the arc frame 22, and a plug-in handle 25 is provided on the blocking plate 24, and the plug-in handle 25 can be used to cover the blocking plate 24 on the upper end of the arc frame 22, and the blocking plate 24 blocks the upper end of the arc frame 22 to prevent foreign objects from entering the arc frame 22.

[0038] At the same time, the arc frame 22 can also seal and protect the headrest 21 in the initial state, preventing the headrest 21 from being exposed to the air for a long time and being contaminated with bacteria, thereby causing accidental infection to the patient.

[0039] During use, the arc frame 22 is first removed from the arc plate 20, and then the patient's head can be rested on the headrest 21. Then, the sealing plate 24 is removed from the arc frame 22 through the plug-in handle 25, and the oxygen mask inside the arc frame 22 is taken out to supply oxygen to the patient, increase the oxygen reserve in the patient's body, and prepare for intubation.

[0040] Continue to refer to Figure 1 As shown, specifically, it includes an insertion groove 3 and a sealing strip 30 , the upper end of the protection box 1 is provided with an insertion groove 3 distributed along its extension section, and the lower end of the cover plate 11 is provided with a sealing strip 30 corresponding to the insertion groove 3 , and the insertion groove 3 is used to accommodate the sealing strip 30 .

[0041] That is, after the cover 11 covers the upper end surface of the protection box 1, the sealing strip 30 will enter the insertion groove 3, which can improve the sealing performance between the cover 11 and the upper end surface of the protection box 1, and at the same time increase the friction area between the cover 11 and the upper end of the protection box 1, so that the cover 11 can be limited at the upper end of the protection box 1 and will not unfold. At the same time, a torsion spring is also installed at the hinge between the cover 11 and the protection box 1, which drives the cover 11 to cover the protection box 1 in the initial state, so that the medical staff can lift the protection box 1 by pulling the handle 12 and the cover 11 to move it. During use, the protection box 1 is placed on the ground, and the patient's head leans on the headrest 21. At this time, the protection box 1 has been limited, and then the sealing strip 30 is moved out of the insertion groove 3 by pulling the handle 12, and the cover 11 is opened from the upper end of the protection box 1.

[0042] Reference Figure 5 As shown, specifically, a T-shaped partition plate 4 is provided inside the protection box 1 , and the partition plate 4 divides the position of the raised portion of the protection box 1 into a first placement cavity 40 and a second placement cavity 41 .

[0043] It can be seen from this that the independent cavities for placing the first cavity 40 and the second cavity 41 can be used to place medical devices separately, thereby increasing the classified placement area in the protective box 1 to improve the ability to place different medical devices separately.

[0044] Reference Figure 6 and Figure 7 As shown, a lifting unit 5 for placing medical devices is also provided inside the protective box 1; specifically, the lifting unit 5 includes a strip plate 50, a placement plate 51, a limit frame 52, a swing plate 53, a limit shaft 54, a supporting plate 55, a placement groove 56 and a bending handle 57, two strip plates 50 are symmetrically arranged on the inner bottom wall of the protective box 1, and several placement plates 51 are evenly spaced and distributed on the upper end of the strip plates 50, and the limit frames 52 are symmetrically arranged on the lower end of the placement plates 51, the upper end of the strip plates 50 is symmetrically hinged with swing plates 53, and the two swing plates 53 are staggered, and one side of the swing plate 53 is plugged with a limit shaft 54 ​​located on the inner side of the corresponding limit frame 52.

[0045] That is, when the placement plate 51 at the lower end is driven by external force to move in the up and down directions, the corresponding swing plate 53 will also drive the corresponding limit axis 54 to slide in the limit frame 52, and the other end of the swing plate 53 will also swing at the hinge point on the strip plate 50, and the swing plate 53 will swing along with the up and down movement of the placement plate 51.

[0046] Swinging plates 53 are symmetrically hinged on both sides of the placement plate 51, and two adjacent swinging plates 53 are staggered. A limiting shaft 54 ​​is also provided on one side of the swinging plate 53, which is slidably inserted into the inner side of the corresponding limiting frame 52, and the uppermost placement plate 51 is not hinged with a swinging plate 53.

[0047] Similarly, when the topmost placement plate 51 is pulled by an external force, it will also drive the corresponding swing plate 53 to swing, and synchronously, the remaining swing plates 53 will also swing synchronously, and the spacing between the swing plates 53 will also increase or decrease. The swing plate 53 is also provided with a damping device at its hinge point, that is, when the swing plate 53 is not driven by an external force, it will stop swinging, so that the placement plate 51 will remain at this height after being separated by a certain distance and will not fall.

[0048] A supporting plate 55 is provided at the upper end of the placement plate 51, and a plurality of placement grooves 56 are provided on the supporting plate 55 along its extended section. The placement grooves 56 are used to place strip-shaped instruments such as cannulas and syringes, so that they can be placed separately. When medical staff need to take them, they can be taken from the placement grooves 56. When the placement plates 51 are pressed against each other, the bottom of the placement plates 51 will block the placement grooves 56 at the lower end, and after the cover plate 11 is covered, the placement grooves 56 at the uppermost end will also be blocked, so that the instruments in the placement grooves 56 will not fall off. The placement grooves 56 are used to place cannulas and intubation auxiliary instruments. The uppermost supporting plate 55 is symmetrically provided with bending handles 57, and medical staff lift the placement plates 51 uniformly by the placement handles.

[0049] Reference Figure 8 and Fig. 9 As shown, a positioning unit 6 for assisting the insertion of the intubation is provided on one side of the uppermost placement plate 51; specifically, the positioning unit 6 includes a sliding plate 60, a support bar 61, a rolling ball 62, a through groove 63, a push spring rod 64 and a limiting ball 65. The two sliding plates 60 are symmetrically slidably arranged on one side of the placement plate 51, and a support bar 61 is provided on the corresponding side of the two sliding plates 60. When driven by an external force, the support bar 61 can drive the sliding plate 60 to move in the front-rear direction under the limiting guide of the corresponding placement plate 51.

[0050] A ball 62 is arranged between the support bars 61 for rotation together, and a through groove 63 is opened inside the ball 62. The through groove 63 is used to insert the guide tube. When in use, the guide tube is first inserted into the through groove 63, and the ball 62 is driven to rotate between the support bars 61 through the guide tube to adjust the angle of the guide tube. Then, one end of the guide tube is inserted into the patient's mouth, and then the intubation tube is inserted into the guide tube. The intubation operation is performed on the patient under the guide tube, and there is an indirect limit of the ball 62 on one side of the guide tube, so that the medical staff can free their hands to perform the intubation operation.

[0051] The inner wall of the through slot 63 is provided with several structural cavities distributed along its axis, and a push spring rod 64 is arranged in the structural cavity. The telescopic end of the push spring rod 64 is located in the through slot 63, and a limit ball 65 is arranged to rotate toward one side of the axis of the through slot 63.

[0052] That is, the outer diameters of the guide tubes are different, so after the guide tube is inserted into the through groove 63, the outer wall of the guide tube will contact the limiting ball 65 of the telescopic part of the push spring, and then the telescopic end of the push spring rod 64 will be driven to be retracted through the limiting ball 65. After the insertion is completed, the push spring rod 64 can use its telescopic end and the limiting ball 65 to tighten and limit the guide tube, and because the limiting ball 65 can rotate, the guide tube can still move up and down, so that the guide tube can be inserted into the patient's mouth.

[0053] Example 2: Reference Fig.10 As shown, on the basis of the first embodiment, in order to enable the protection box 1 to remain horizontal when placed on a sloping ground, a horizontal component 7 is provided at the bottom of the protection box 1; specifically, the horizontal component 7 includes a support column 70 and a circular plate 71, four thread grooves are evenly spaced at the four corners of the bottom of the protection box 1, and the support column 70 is threadedly connected in the thread groove, and a circular plate 71 is sleeved on the side of the support column 70 away from the protection box 1, and the circular plate 71 is used to contact the ground and support the protection box 1.

[0054] During use, the medical staff lifts the protective box 1 as a whole by pulling the handle 12 according to the slope of the ground, and then drives the support column 70 to rotate in the corresponding thread groove through the circular plate 71 alone, so that the support column 70 moves out of the thread groove or enters into the thread groove. After the adjustment is completed, the protective box 1 is placed on the ground so that the circular plate 71 can contact the ground, and the height difference between the support columns 70 is offset by the slope of the ground.

[0055] During work: the first step is to lift the protective box 1 to the patient's side by pulling the handle 12, then remove the arc frame 22 from the arc plate 20, and then place the patient's head on the pillow assembly 2 to assist in supporting his head, so as to facilitate the subsequent intubation operation.

[0056] Step 2: Open the cover plate 11 and the blocking plate 24 and stop blocking the upper ends of the protection box 1 and the arc frame 22 in turn, take out the arc frame 22, the first cavity 40 and the second cavity 41, and prepare the patient for intubation.

[0057] Step 3: When performing intubation, separate the placement plates 51 in the lifting unit 5 from each other by bending the handle 57, then take out the required intubation instrument from the placement slot 56, and then insert the guide tube into the positioning unit 6, so that one side of the guide tube can be limited separately, and the medical staff can free their hands to perform other preparatory operations. Finally, the medical staff inserts the cannula into the guide tube, and the cannula enters the patient's body under the limit guidance of the guide tube to perform the intubation operation.

[0058] Step 4: After the protection box 1 is placed on the ground, the slope of the ground will make the protection box 1 unstable. At this time, the four corners of the bottom of the protection box 1 are assisted in leveling through the horizontal component 7 so that the protection box 1 can be placed steadily, and then the patient's head can be placed stably on the pillow component 2.

[0059] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0060] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
