Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an airway opening pillow. Background Art

[0002] In clinical practice or during surgery, patients may have tracheal obstruction. Medical staff often use the method of tilting the head back and lifting the forehead to lift the patient's chin to open the airway. However, in actual clinical operations, there are no auxiliary medical devices specifically for opening the patient's airway. Other common items (such as towels, water bags, etc.) are often used as temporary pads, placed under the back of the patient's neck for support to facilitate the opening of the patient's airway. Especially for younger children, when using temporary pads, they will move their bodies or heads due to the foreign body sensation and discomfort, which will affect the treatment process, and most children are unwilling to cooperate with medical staff. Therefore, when doctors perform airway opening surgery on younger children, the treatment process becomes more difficult.

[0003] In the prior art, for example, a patent document with publication number CN107184035A discloses an airway opening pillow, which also discloses a head support portion, a neck support portion and a shoulder support portion. In actual application, when the height of the patient's headrest needs to be adjusted, multiple adjustment pads are required to adjust the height. On the one hand, it is cumbersome, and on the other hand, the patient needs to raise his head to operate, which is not conducive to the normal treatment. In addition, the headrest cannot be adjusted in angle, and its application range is small. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figure 1-Figure 2 As shown, the utility model is an airway opening pillow, comprising a base plate 1, on which a headrest mechanism is arranged, the headrest mechanism comprising a shoulder support portion 2 for supporting the patient's shoulders, a head support portion 201 for supporting the patient's head is arranged at the end of the shoulder support portion 2, and the head support portion 201 is in a "convex" shape and is smoothly connected to the shoulder support portion 2; in one implementation of this embodiment, during the use of the airway opening pillow, the medical staff places the base plate 1 on the nursing bed, supports the patient's shoulders through the shoulder support portion 2, and supports the patient's head position through the head support portion 201;

[0026] In this embodiment, the shoulder support 2 and the head support 201 are made of memory foam, which can improve the comfort of the patient when leaning on the pillow, and has the effect of ventilation and heat dissipation;

[0027] Among them, a limiting groove 202 for limiting the patient's head is provided in the middle position of the head support part 201, and a guide groove 203 is provided at the bottom of the limiting groove 202. A support pad 3 for supporting the back of the patient's head is arranged in the guide groove 203 in a sliding manner along the vertical direction, and the support pad 3 is connected to a lifting part that drives it to move in the vertical direction; it can be explained that when the airway opening pillow is in use, the patient's head can be embedded in the limiting groove 202 for limiting, so that the patient's head is more stable and less likely to be deflected. At the same time, the back of the patient's head is supported by the support pad 3 arranged in the limiting groove 202. When the height of the patient's head needs to be adjusted, the support pad 3 can be driven to rise and fall along the guide groove 203 by the lifting part, and there is no need to use other support pads to support the patient's head, so the adjustment is more convenient;

[0028] In addition, the support pad 3 is also made of memory foam.

[0029] Example 2

[0030] Based on Example 1, please refer to Figure 3 and Figure 4 The lifting part includes a support frame 211 arranged in the head support part 201, and an opening is provided on the support frame 211, which is a closed structure on all sides. A support plate 210 is slidably arranged in the support frame 211, and the support pad 3 is fixedly arranged on the support plate 210. The support plate 210 and the side wall of the support frame 211 enclose an air cavity 208, and the air cavity 208 is connected to an inflation mechanism arranged outside the head support part 201 to transport gas into the air cavity 208; it can be explained that when it is necessary to adjust the height of the patient's head, gas is transported into the air cavity 208 through the inflation mechanism, and the support plate 210 can be pushed to move toward the opening direction of the support frame 211 under the action of air pressure, thereby synchronously pushing the support pad 3 to rise;

[0031] In this embodiment, the inflation mechanism includes an air supply pipe 204 connected to the air cavity 208, the other end of the air supply pipe 204 is connected to the inflatable bag 205, and the other end of the inflatable bag 205 is connected to the air inlet pipe 206, wherein a one-way valve limited to air intake is provided between the air inlet pipe 206 and the inflatable bag 205, and a one-way valve limited to exhaust is provided between the air supply pipe 204 and the inflatable bag 205; it can be explained that when inflating the air cavity 208, the medical staff presses the inflatable bag 205 back and forth, and the external gas can first enter the inflatable bag 205 through the air inlet pipe 206, and finally enter the air cavity 208 through the air supply pipe 204, thereby achieving the inflation effect, and the operation is very convenient.

[0032] Furthermore, an exhaust pipe 207 connected to the air cavity 208 is arranged on the outside of the head support part 201, and a valve is arranged between the exhaust pipe 207; it can be explained that when it is necessary to adjust the support pad 3 to descend, the exhaust pipe 207 is opened through the valve to discharge the gas in the air cavity 208, and the support pad 3 can be lowered, which is convenient to operate.

[0033] In addition, several groups of telescopic springs 209 are provided in the air cavity 208, one end of the telescopic spring 209 is fixed to the bottom of the support frame 211, and the other end is fixed to the support plate 210; specifically, when the support pad 3 is driven to rise, the telescopic spring 209 is in a stretched state, which makes it easier to drive the support pad 3 to reset when exhausting.

[0034] Example 3

[0035] Based on Example 2, please refer to Figure 1-Figure 2 , the bottom plate 1 is symmetrically provided with a support 101, the end of the shoulder support part 2 is rotatably connected to the support 101 through a support shaft 102, wherein a limit seat 103 is fixedly provided on the bottom plate 1, a screw rod 4 is rotatably provided between the limit seats 103, a handle 401 is fixedly provided at the end of the screw 4, a nut 402 is spirally sleeved on the screw 4, a push rod 403 is rotatably provided on the nut 402, and the end of the push rod 403 is rotatably connected to the head support part 201;

[0036] It can be explained that during the treatment process, when the patient's head angle needs to be adjusted, the screw 4 is driven to rotate by rotating the handle 401. During the movement of the nut 402 on the screw 4, the shoulder support part 2 and the head support part 201 can be pushed by the push rod 403 to rotate around the support shaft 102, so as to adjust the angle of the patient's head, which is easy to operate.
