Description

Technical Field

[0001] This utility model relates to the technical field of medical auxiliary devices, and in particular to a fast-inflating shoulder pillow that can be fixed in front of the chest for continuous airway opening. Background Technology

[0002] In the resuscitation of critically ill patients, ensuring adequate cardiac circulation and ventilation is fundamental to the rescue. A crucial step in maintaining effective ventilation is bag-valve-mask oxygenation. Opening the patient's airway during bag-valve-mask oxygenation is of paramount importance. A good airway opening can provide sufficient ventilation support and ensure adequate ventilation and oxygen reserves for the patient's resuscitation.

[0003] Currently, the most commonly used airway opening technique during bag-valve-mask oxygenation in resuscitation is the EC maneuver. The left hand uses a "3-2" technique: three fingers form an "E" shape to open the mouth, and two fingers form a "C" shape to secure the mask. The right hand simultaneously squeezes the bag for ventilation. This technique's advantage lies in its rapid initiation, making it suitable for emergency situations (initiation time <10 seconds). However, this method also has drawbacks. For single-person resuscitation using the EC maneuver, the operator's arm is constantly supporting the chin, which can easily lead to fatigue over time. Literature shows that the operator's hand muscle strength decreases by >20% per minute. Therefore, the "E" in the EC maneuver is the primary force used for continuous airway opening, and the quality of airway opening decreases significantly with the operator's declining hand strength over time. Therefore, in clinical practice, two people are often needed to perform bag-valve ventilation: one person uses the EC maneuver with both hands to open the airway, and the other administers oxygen via the bag, which consumes manpower during resuscitation.

[0004] At the same time, if the patient is receiving oxygen via bag valve while undergoing cardiopulmonary resuscitation (CPR), and the CPR practitioner is applying downward chest compressions with the heels of their hands, the person providing bag valve ventilation must resist both the patient's own body weight and the downward vertical force applied by the CPR practitioner. Ensuring adequate airway opening becomes even more difficult in this situation.

[0005] The same situation can also occur during the endotracheal intubation and tracheotomy of critically ill patients. Insufficient airway opening can easily lead to poor visual exposure during intubation and insufficient airway opening time during tracheotomy.

[0006] When prolonged airway opening is required, a comfortable and supportive shoulder pillow, as disclosed in utility model patent CN216221050U, and a medical shoulder pillow, as disclosed in utility model patent CN217430368U, are occasionally used to support the patient's shoulders and back, thus opening the airway. However, traditional shoulder pillows generally have the following drawbacks, including poor fixation, easy slippage of the body position, especially during simultaneous chest compressions, and inability to adapt to different body types, resulting in poor practicality. Therefore, there is an urgent need for a fast-inflating shoulder pillow that can be fixed in front of the chest for continuous airway opening to solve the above problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a fast-inflating shoulder pillow that can be fixed in front of the chest and keeps the airway open. The patient lies flat on the base plate with the patient's shoulders and back on the support mechanism. The support mechanism is inflated by an inflation mechanism, which expands the support mechanism to support the patient's shoulders and back, thereby tilting the patient's head back and opening the patient's airway. At the same time, the patient is restrained by a limiting mechanism to prevent the patient from slipping, thereby improving the practicality of the device.

[0008] This utility model discloses a fast-inflating shoulder pillow that can be fixed in front of the chest and maintain continuous airway open, including a base plate; it also includes a support mechanism, a limiting mechanism and an inflation mechanism, with the support mechanism and the limiting mechanism both mounted on the base plate;

[0009] The support mechanism supports the patient's shoulders and back, the limiting mechanism limits the patient's position, and the inflation mechanism adjusts the height of the support mechanism.

[0010] The patient lies flat on the base plate with their shoulders and back resting on the support mechanism. Inflation is made into the support mechanism by the inflation mechanism, causing it to expand and support the patient's shoulders and back, which in turn tilts the patient's head back, opening the airway. At the same time, the limiting mechanism restrains the patient to prevent them from slipping, thereby improving the practicality of the equipment.

[0011] Preferably, the support mechanism includes a scapular airbag and a connector. The top of the base plate has a groove, the scapular airbag is installed in the groove of the base plate, the connector is installed on the base plate, and the interior of the base plate has an exhaust passage. The connector communicates with the interior of the scapular airbag through the exhaust passage. The patient lies flat on the base plate with their shoulders and back on the scapular airbag. Then, the inflation mechanism is connected to the connector, allowing the inflation mechanism to inflate the scapular airbag. The scapular airbag expands and supports the patient's shoulders and back, thereby improving the practicality of the device.

[0012] Preferably, the limiting mechanism includes two sets of sliders, two sets of screws (first type), two sets of restraint straps, a support frame, a baffle, two sets of screws (second type), and two sets of screws (third type). The two sets of sliders are slidably mounted on the front and rear of the base plate, respectively. A long through hole is provided in the middle of the base plate.

One end of each set of restraint straps is mounted onto the two sets of sliders, and each set of restraint straps is provided with Velcro A and Velcro B. The support frame is slidably mounted on the left side of the base plate. The two sets of screws (third type) are threaded onto the front and rear of the base plate, respectively. The baffle is hinged to the support frame. The two sets of screws (second type) are threaded onto the front and rear of the support frame, respectively. Limiting holes are provided at the front and rear of the baffle, and two sets of limiting holes are provided on the left side of the baffle. The device consists of two sets of sliding blocks. The positions of the two sets of restraint straps are adjusted by sliding the two sets of sliders. Then, screw one is rotated so that it passes through the sliders and rests against the base plate, limiting the position of the two sets of sliders. Next, Velcro A on one set of restraint straps is attached to Velcro B on the other set to restrain the patient. The support frame is then pulled out of the base plate or retracted into it to adjust the position of the baffle. Screw three is then rotated so that it rests against the support frame, limiting its position. The baffle is then moved to raise it, positioning the patient's legs in the two limiting slots of the baffle. Screw two is then rotated so that one end of screw two passes through the support frame and extends into the limiting hole of the baffle, blocking the patient's groin and legs and preventing slippage, thus improving the device's usability.

[0013] Preferably, the baffle has a recess in the middle; the recess on the baffle protects the groin area of ​​male patients, thereby improving the practicality of the device.

[0014] Preferably, the inflation mechanism includes a manual pressurizing ball, a three-way pressure relief valve, and a quick connector. The exhaust port of the manual pressurizing ball is installed on one end of the three-way pressure relief valve, and the quick connector is installed on the other end of the three-way pressure relief valve. The quick connector is connected to the connector head, and by pressurizing the manual pressurizing ball, air passes through the three-way pressure relief valve, the quick connector, and the exhaust passage in the base plate in sequence, allowing air to enter the scapular airbag. After the emergency or treatment is completed, the three-way pressure relief valve is opened to expel the air from the scapular airbag, thereby improving the practicality of the device.

The inflation cylinder is installed on one end of the two-way pressure relief valve, and the two-way quick connector is installed on the other end of the two-way pressure relief valve. The two-way quick connector is opened to open the inflation cylinder, allowing compressed gas to pass sequentially through the three-way pressure relief valve, the two-way quick connector, the connecting head, and the exhaust passage in the base plate, allowing the compressed gas to enter the scapular airbag. After the emergency or treatment is completed, the two-way pressure relief valve is opened again to expel the air from the scapular airbag, thereby improving the practicality of the equipment.

[0016] Preferably, both sets of limiting grooves of the baffle are provided with silicone pads; thereby improving patient comfort.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the patient lies flat on the base plate with the patient's shoulders and back on the support mechanism. The support mechanism is inflated by the inflation mechanism, which expands the support mechanism to support the patient's shoulders and back, thereby tilting the patient's head back and opening the patient's airway. At the same time, the patient is restrained by the limiting mechanism to prevent the patient from slipping, thereby improving the practicality of the device. Attached Figure Description
