Description

Technical Field

[0001] This utility model relates to the field of medical inflatable pillow technology, specifically to an inflatable pillow for post-anesthesia observation. Background Technology

[0002] Post-anesthesia patients are often observed for a period of time. To avoid adverse reactions such as headaches caused by low intracranial pressure, patients are often asked to lie flat without a pillow for several hours. Due to the residual effects of anesthetic, patients may experience posterior displacement of the tongue, obstructing the airway. The quickest way to prevent this is to lift the patient's chin into a head-tilt position, as the physiological structures of the throat will open the airway when the head is tilted back. However, patients may unconsciously adjust their head position, leading to airway obstruction. Because the post-anesthesia recovery room is often crowded with fewer medical staff, there may be instances where observation is not timely, making it impossible to adjust the patient's head position promptly, thus increasing the patient's safety risks. Manually adjusting the patient's head multiple times is also labor-intensive.

[0003] Patent publication number "CN202069973U" discloses an inflatable pillow for anesthesia, comprising an air-bag type pillow body with an arc shape corresponding to the head position. An inflation tube is provided on the pillow body, connected to an inflation device. An adjusting valve is provided on the inflation tube, and an exhaust port with an exhaust valve is also provided on the pillow body. In use, if the anesthesia mask does not fit well against the mouth and nose, the adjusting valve can be opened to inflate the pillow body and adjust the angle of the patient's head to ensure proper fit. This inflatable pillow is suitable for use during anesthesia; however, its use during post-anesthesia observation can easily lead to intracranial hypotension, and manually adjusting the inflation and deflation of the pillow is labor-intensive. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned background technology and provide an air pillow for post-anesthesia observation.

[0005] The technical solution adopted in this utility model is: a post-anesthesia observation air pillow, which includes,

[0006] An airbag pillow body, wherein a transverse bladder is provided on one longitudinal side of the airbag pillow body. When inflated, the transverse bladder is higher than the middle area of ​​the pillow surface of the airbag pillow body, and is used to lift the patient's neck.

[0007] An air pump, the air pump pipeline of which connects the airbag pillow body and the transverse airbag body;

[0008] The sensor, whose tubing is connected to a nasal cannula, is used to deliver carbon dioxide via the nasal cannula to detect the patient's end-tidal carbon dioxide concentration;

[0009] A controller, which is communicatively connected to a sensor and an air pump, is used to regulate the air pump's inflation based on the carbon dioxide concentration.

[0010] Furthermore, it also includes a pressure sensor for detecting the air pressure of the airbag pillow body; the pressure sensor is located on the air pump or the airbag pillow body or the pipeline between the air pump and the airbag pillow body.

[0011] Furthermore, the transverse bladder is connected to the airbag pillow body, and the inflation pump is connected to the airbag pillow body through the first inflation tube.

[0012] Furthermore, the airbag pillow body is provided with a protruding bladder on the pillow surface, and the protruding bladder is connected to the air pump pipeline.

[0013] Furthermore, the protruding bladder body and the airbag pillow body are not connected, and the inflation pump is connected to the airbag pillow body and the protruding bladder body respectively through the first inflation pipe and the second inflation pipe.

[0014] Furthermore, the protruding bladder is longitudinally positioned on the airbag pillow, and after inflation, it is higher in the middle and lower on both sides laterally.

[0015] Furthermore, the transverse bladder body and the airbag pillow body are integrally formed, and the structure becomes arc-shaped after inflation.

[0016] Furthermore, the controller is used to regulate the inflation and deflation of the air pump according to the carbon dioxide concentration.

[0017] Furthermore, the nasal cannula includes an oxygen delivery side tube and a collection side tube that is offset at one end from the end of the oxygen delivery side tube. The opposite ends of the oxygen delivery side tube and the collection side tube are not connected, and an oxygen delivery hole and a collection hole are respectively provided on the same side of the opposite ends.

[0018] Furthermore, there are two oxygen delivery holes and two collection holes, which are stacked one on top of the other and placed at the nostril.

[0019] Furthermore, the outer wall of one end of the collection side tube is connected to the outer wall of one end of the oxygen delivery side tube; the collection hole of the collection side tube is provided with a collection protrusion.

[0020] Furthermore, the nasal cannula also includes an adjustment slider, which has two sliding holes, in which the oxygen delivery tube and the collection tube are slidably disposed respectively.

[0021] The beneficial effects of this utility model include: 1. The sensor connected to the nasal cannula can detect the patient's end-tidal carbon dioxide concentration and determine the patient's airway obstruction. The controller automatically adjusts the inflation pump according to the carbon dioxide concentration. After inflation, the transverse bag can elevate the patient's neck, allowing the patient to tilt their head back and open the airway, preventing the patient's tongue from falling back and obstructing the airway. The controller inflates according to the carbon dioxide concentration, which has high timeliness and sensitivity. It can also maintain the patient in a supine position without a pillow for as long as possible, without the need for manual adjustment of the patient's head position, saving manpower.

[0022] 2. The air pressure of the airbag pillow body is detected by a pressure sensor, which can prevent damage to the airbag pillow body due to excessive pressure;

[0023] 3. When the transverse bladder body is connected to the airbag pillow body, only one inflation tube is needed to connect to the inflation pump, making the structure simpler;

[0024] 4. After inflation, the protruding sac protrudes from the occipital surface, causing the patient's head to turn to one side, thus preventing vomit or secretions from flowing back and blocking the airway;

[0025] 5. The protruding bladder body and the airbag pillow body are not connected. The air pump is connected through two air tubes to ensure the air pressure of the protruding bladder body, so as to support the patient's occipital region and turn the head to one side.

[0026] 6. The structure of the protruding sac is simple. It is set longitudinally on the pillow surface of the airbag pillow. After inflation, it is high in the middle and low on both sides, which makes it easy for the patient's head to turn to one side.

[0027] 7. The inflation and deflation of the air pump can be controlled by the controller, and the airbag pillow and protruding sac can be automatically inflated and deflated according to the carbon dioxide concentration, which can prolong the time the patient is in a supine position without a pillow and avoid the adverse effects of low intracranial pressure.

[0028] 8. The nasal cannula collects the patient's end-tidal carbon dioxide concentration through the collection side tube and delivers oxygen to the patient through the oxygen delivery side tube. This avoids blocking the patient's nostrils with the collection side tube and ensures the amount of oxygen inhaled when collecting carbon dioxide concentration.

[0029] 9. The outer wall of the collection side tube is connected to the oxygen delivery side tube, which allows both the collection hole and the oxygen delivery hole to be aligned with the nostril. The collection protrusion can be extended into the patient's nasal cavity to increase the effective collection volume.

[0030] 10. The slider is slidably connected to the oxygen delivery tube and the collection tube through two sliding holes, which facilitates sliding adjustment to fix the nasal cannula to the head.

[0031] This utility model relates to an air pillow for post-anesthesia observation. It uses a sensor connected to a nasal cannula to detect the patient's end-tidal carbon dioxide concentration. The controller automatically adjusts the inflation pump according to the carbon dioxide concentration. After inflation, the transverse bladder protrudes from the pillow surface, which can raise the patient's neck and open the airway, preventing the tongue from falling back and blocking the airway. It can automatically adjust the patient's head position, improve airway obstruction, and save manpower. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] This utility model relates to a post-anesthesia observation pillow, used to adjust the patient's head position after anesthesia. Anesthetized patients may experience posterior displacement of the tongue, obstructing the airway. This observation pillow, connected to a nasal cannula 5 via a sensor, can detect the patient's end-tidal carbon dioxide concentration to determine the degree of airway obstruction. The controller 4 automatically adjusts the inflation pump 3 based on the carbon dioxide concentration. After inflation, the transverse bladder 12 elevates the patient's neck. Due to the physiological structure of the pharynx, the airway is opened when the head is tilted back, preventing airway obstruction due to posterior displacement of the tongue. The controller 4 inflates based on carbon dioxide concentration, providing high timeliness and sensitivity (compared to blood oxygen monitoring). It also helps maintain the patient in a supine position without a pillow for as long as possible, eliminating the need for manual head position adjustments and saving manpower.

[0041] A type of air pillow for post-anesthesia observation, specifically, such as... Figure 1-3 As shown, the device includes an airbag pillow body 1, an air pump 3, a sensor, and a controller 4. A transverse bladder 12 is connected to one longitudinal side of the airbag pillow body 1. When inflated, the transverse bladder 12 is higher than the middle area of ​​the pillow surface 11 of the airbag pillow body 1, which is used to lift the patient's neck. The pillow surface 11 can be an arc-shaped concave surface. The air pump 3 is connected to the airbag pillow body 1 and the transverse bladder 12 through a tubing. The sensor tubing is connected to a nasal cannula 5, which is used to deliver carbon dioxide through the nasal cannula 5 to detect the patient's end-expiratory carbon dioxide concentration. Figure 2 The sensor is located inside the controller 4. The sensor is existing technology and can be used with a carbon dioxide detector. The controller 4 is communicatively connected to the sensor and the air pump 3, and is used to adjust the air pump 3 to inflate according to the carbon dioxide concentration.

[0042] After anesthesia, patients often lie supine without a pillow. When the inflatable cuff 1 is placed under the patient's head and not inflated, it helps prevent intracranial hypotension. The sensor is connected to the nasal cannula 5 (not shown in the diagram). The nasal cannula 5, worn in the patient's nose, delivers the patient's exhaled carbon dioxide to the sensor. The sensor detects the patient's end-tidal carbon dioxide concentration and transmits this concentration to the controller 4. When the sensor detects a low end-tidal carbon dioxide concentration, it indicates airway obstruction. The controller 4 then adjusts the inflation pump 3 to automatically inflate the cuff 1 and the transverse cuff 12 based on a comparison of the carbon dioxide concentration with a preset threshold. Inflated transverse cuff 12 lifts the patient's neck, opening the airway and improving airway ventilation.

[0043] In one embodiment, the post-anesthesia observation air pillow also includes a pressure sensor for detecting the air pressure of the airbag pillow body 1; by detecting the air pressure of the airbag pillow body 1 by the pressure sensor, excessive pressure can be avoided and damage to the airbag pillow body 1 can be prevented. The pressure sensor is located on the inflation pump 3, or on the airbag pillow body 1, or on the pipeline between the inflation pump 3 and the airbag pillow body 1; preferably, the pressure sensor is located on the inflation pump 3, to avoid the inconvenience of using it if located on the airbag pillow body 1.

[0044] The post-anesthesia observation air pillow also includes a pressure sensor. In one embodiment, the transverse bladder 12 is connected to the air pillow body 1, and the inflation pump 3 is connected to the air pillow body 1 through the first inflation tube 6. Only one inflation tube is needed to connect the inflation pump 3, making the structure simpler.

[0045] Preferably, the transverse bladder 12 is integrally formed with the airbag pillow 1, and after inflation, it has an arc-shaped protrusion structure to improve patient comfort.

[0046] Anesthesia may cause gastrointestinal reactions in patients, leading to vomiting or increased secretions. For example... Figure 1 As shown, the airbag pillow body 1 has a protruding bladder 2 located on the pillow surface 11. The protruding bladder 2 is connected to the air pump 3 via a pipeline. The protruding bladder 2 is preferably located in the middle area of ​​the pillow surface 11. After being inflated, the protruding bladder 2 is higher than the pillow surface 11, lifting the back of the patient's head. This is used to turn the patient's head to one side, which is conducive to the discharge of vomit and secretions from the corner of the mouth and to prevent the backflow of vomit or secretions from blocking the airway.

[0047] In a preferred embodiment, such as Figure 2 The protruding sac 2 is not connected to the airbag pillow 1. The air pump 3 is connected to the airbag pillow 1 and the protruding sac 2 through the first air pipe 6 and the second air pipe 7 respectively. This ensures that the air pressure of the protruding sac 2 can support the patient's occipital region and turn their head to one side.

[0048] More preferably, the pressure sensor can also detect the air pressure in the protruding bladder 2. In actual use, two pressure sensors can be used to detect the air pressure in the airbag pillow 1 and the protruding bladder 2 respectively.

[0049] In some embodiments, such as Figure 1 As shown, the protruding sac 2 is longitudinally positioned on the airbag pillow 1, and after inflation, it is higher in the middle and lower on both sides, like an arc-shaped protrusion. Its structure is simple and makes it easy to tilt the patient's head to one side.

[0050] In one embodiment, the controller 4 is used to regulate the inflation and deflation of the air pump 3 according to the carbon dioxide concentration. This control method can automatically deflate the observation pillow. After the sensor detects that the patient's end-tidal carbon dioxide concentration is within the normal range for a period of time, the controller 4 can automatically regulate the deflation of the air pump 3, either by opening the valve or by suctioning air, so that the patient can continue to be in a supine position without a pillow, thereby reducing the adverse effects of intracranial hypotension.

[0051] In one embodiment, such as Figure 1-2As shown, the nasal cannula 5 includes an oxygen delivery side tube 51 and a collection side tube 52, one end of which is offset and connected to the other end of the oxygen delivery side tube 51. The opposing ends of the oxygen delivery side tube 51 and the collection side tube 52 are not connected, and each has an oxygen delivery hole 511 and a collection hole 521 on the same side of its opposing ends. The patient's end-tidal carbon dioxide concentration is collected through the collection side tube 52, while the oxygen delivery side tube 51 delivers oxygen to the patient. This avoids the collection side tube 52 blocking the patient's nostrils, ensuring the oxygen intake volume when collecting carbon dioxide concentration.

[0052] The nasal cannula 5 includes a collection side tube 52 and an oxygen delivery side tube 51, such as Figure 2-3 As shown, the outer wall of one end of the collection side tube 52 is connected to the outer wall of one end of the oxygen delivery side tube 51; the collection port 521 of the collection side tube 52 is provided with a collection protrusion 522. During exhalation, the outflow rate is greater than the oxygen delivery rate. The collection protrusion 522 is inserted into the nostril, and the oxygen delivery port 521 is located at the nostril. This reduces the adverse effect of oxygen from the oxygen delivery side tube on the detection, making it easier for the sensor to accurately collect the carbon dioxide concentration. In a specific application, there are two collection ports 521 and two oxygen delivery ports 511. The collection ports 521 and oxygen delivery ports 511 are stacked one-to-one to be aligned with the nostril simultaneously. That is, one collection port 521 and one oxygen delivery port 511 form a group aligned with the same nostril. The collection side tube 52 is connected to the outer wall of the oxygen delivery side tube 51, so that both the collection port 521 and the oxygen delivery port 511 can be aligned with the nostril. The collection protrusion 522 can be extended into the patient's nasal cavity to increase the effective collection volume.

[0053] The nasal cannula 5 includes a collection side tube 52 and an oxygen delivery side tube 51, such as Figure 1-2 As shown, the nasal cannula 5 also includes an adjusting slider 53, which has two sliding holes. The oxygen delivery tube 51 and the collection tube 52 are slidably disposed in the two sliding holes, respectively. There is friction between the adjusting slider 53 and the oxygen delivery tube 51 and the collection tube 52, which can adjust the size of the ring formed by the oxygen delivery tube 51, the collection tube 52 and the adjusting slider 53, so as to facilitate sliding adjustment and fix the nasal cannula 5 to the head.

[0054] In a specific embodiment, such as Figure 1 As shown, the transverse bladder 12 is integrally formed with the airbag pillow body 1, and the protruding bladder 2 is not connected to the airbag pillow body 1. The inflation pump 3 is connected to the airbag pillow body 1 and the protruding bladder 2 through the first inflation pipe 6 and the second inflation pipe 7 respectively. The inflation pump 3 is equipped with a pressure sensor to detect the air pressure of the protruding bladder 2 and the airbag pillow body 1 respectively. One end of the acquisition side pipe 52 is connected to the sensor, and one end of the oxygen delivery side pipe 51 is used to connect to the oxygen source. The sensor is located on the controller 4.

[0055] In actual use, the uninflated airbag pillow 1 is placed under the patient's head, and one end of the oxygen delivery tube 51 is connected to the oxygen source. When the patient's tongue falls back or vomiting causes airway obstruction, the controller 4 identifies that the patient's end-tidal carbon dioxide concentration is lower than the preset threshold. The controller 4 controls the inflation pump 3 to inflate the airbag pillow 1 and the protruding bladder 2. After inflation, the transverse bladder 12 raises the patient's neck to open the airway. The protruding bladder 2 can lift the back of the patient's head to turn the head to one side to avoid airway obstruction by vomit or other substances. After the patient's end-tidal carbon dioxide concentration remains within the normal range for a period of time, the controller 4 controls the inflation pump 3 to deflate, so that the patient is in a supine position without a pillow, reducing the adverse effects of intracranial hypotension.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
