In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installed", "connected", "connected", and "connector" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0031] The following will refer to the attached Figures 1 to 5 The present invention is described in detail with reference to embodiments.

[0032] In general, the present invention provides a vital sign monitoring device for hospitalized patients, comprising a fixed cylinder 1 with an inner cavity formed therein, baffles 2 fixedly arranged at the front and rear ends of the fixed cylinder 1, an airbag assembly arranged at the inner end of the fixed cylinder 1 and connected to the baffles 2 on both sides, a plurality of elastic components fixedly arranged around the airbag assembly, and a heart rate sensor 6 and a blood oxygen sensor 7 fixedly arranged on the inner side wall of the airbag assembly;

[0033] like Figure 1 and Figure 2 As shown, the elastic component includes a top plate 4 and a first spring 401, the top plate 4 is fixedly connected to the airbag component, a plurality of first springs 401 are fixedly provided on the side of the top plate 4 facing away from the airbag component, one end of the first spring 401 is fixedly connected to the top plate 4, and the other end abuts against the inner wall of the fixed tube 1; the airbag component is connected to the air inlet pipe 304, and the end of the air inlet pipe 304 passes through to the outside of the fixed tube 1.

[0034] In this embodiment, the patient's hand is inserted into the airbag assembly, and the airbag assembly is filled with air through the air inlet pipe 304. The air inlet pipe 304 is closed, so that the airbag assembly wraps and clamps the patient's arm, so that the heart rate sensor 6 and the blood oxygen sensor 7 on the airbag assembly inside the airbag assembly fit closely with the patient's skin, reducing the interference of external factors and providing real-time and accurate monitoring data. In addition, after the airbag is inflated, the elastic component provides an inward clamping force for it, and can also prevent the airbag from being inflated with too much force, causing discomfort to the patient's arm.

[0035] In the elastic component, during specific implementation, as the airbag component is inflated, the first spring 401 will be compressed to provide cushioning for the airbag component to prevent the patient's arm from feeling discomfort. At the same time, the resetting force of the first spring 401 will also squeeze the airbag component to provide a certain clamping force.

[0036] It should be understood that blood oxygen and heart rate monitoring rely on close contact between the sensor and the skin. Blood oxygen saturation is usually obtained by measuring the ratio of oxygenated hemoglobin to reduced hemoglobin in the blood, and this process requires the sensor to accurately capture the blood flow under the skin. Heart rate monitoring is achieved by detecting the tiny vibrations of the skin caused by the heartbeat, which also requires good contact between the sensor and the skin.

[0037] Based on the above settings, in this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the fixed cylinder 1 is also provided with an extrusion component that cooperates with the elastic component. The extrusion component can cooperate with the elastic component to prevent a gap between the patient's arm muscles and the airbag component when exercising, thereby affecting the accuracy of monitoring. The extrusion component includes a thread 101 arranged on the outer wall of the fixed cylinder 1, an inclined block 501 slidably arranged on the fixed cylinder 1, a rotating sleeve 102 screwed to the fixed cylinder 1 through the thread 101, and a pressing plate 5 fixedly arranged at the bottom end of the inclined block 501. The pressing plate 5 corresponds to the elastic component and abuts against the end of the first spring 401.

[0038] In specific implementation, if the patient moves, a gap is generated between the airbag and the skin. At this time, the rotating sleeve 102 is rotated toward the direction of the inclined block 501, so that it abuts against the inclined surface of the inclined block 501, driving the pressing plate 5 to press against the first spring 401, and then transmitting the squeezing force to the airbag, so that the airbag wraps the patient's arm more compactly. In addition, the thread 101 of the rotating sleeve 102 is screwed with the fixed tube 1, which also plays a certain limiting role.

[0039] like Figure 3 As shown, the airbag assembly includes a first airbag 3, a second airbag 301, a third airbag 302, and a fourth airbag 303, which are connected to each other at the ends in sequence. In this embodiment, the inner sides of the first airbag 3, the second airbag 301, the third airbag 302, and the fourth airbag 303 are arc-shaped, which can help the sensor to better fit the patient's skin. In specific implementation, four groups of elastic components are set, which are fixedly arranged on the outer sides of the first airbag 3, the second airbag 301, the third airbag 302, and the fourth airbag 303 in sequence. Corresponding to the four directions of the upper, lower, left, and right of the patient's arm, it is convenient to clamp and wrap the arm more tightly.

[0040] It should be noted that the heart rate sensor 6 is fixedly arranged inside the first airbag 3, and the blood oxygen sensor 7 is fixedly arranged inside the second airbag 301. A plurality of friction strips 8 are fixedly arranged inside the third airbag 302 and the fourth airbag 303 at intervals.

[0041] During specific implementation, the first airbag 3 and the second airbag 301 are used to clamp the detected package, and the third airbag 302 and the fourth airbag 303 are used to fix the patient's arm. Combined with the friction strip 8, the friction between the patient's arm can be increased to prevent the present invention from detaching from the patient's arm and causing an accident.

[0042] It should be further explained that, in order to facilitate the installation of the airbag assembly, in this embodiment, Figure 3 As shown, the airbag assembly is connected to the baffle 2 through a mounting strip 305, one end of the mounting strip 305 is fixedly connected to the airbag assembly, and the other end is plugged into and matched with the baffles 2 on both sides. In specific implementation, the number of mounting strips 305 is set according to actual conditions and is not further limited here.

[0043] Preferably, in order to facilitate the installation of the heart rate sensor 6 and the blood oxygen sensor 7 on the airbag assembly, in the present embodiment, the blood oxygen sensor 7 and the heart rate sensor 6 are fixedly mounted on the inner wall of the airbag assembly via a mounting plate 11, the blood oxygen sensor 7 and the heart rate sensor 6 are fixedly embedded in the mounting plate 11, and the mounting plate 11 is fixedly connected to the airbag assembly.

[0044] In order to further prevent the present invention from being separated from the patient's arm, in this embodiment, a clamping assembly is further provided on one side of the fixing cylinder 1, such as Figure 1 As shown, the clamping assembly includes a fixing ring 9 fixedly connected to the fixing tube 1, guide posts 901 symmetrically slidably arranged on the upper and lower sides of the fixing ring 9, a clamping plate 903 fixedly arranged on the guide post 901 at one end inside the fixing ring 9, and a second spring 902 sleeved on the guide post 901; the clamping plate 903 is arc-shaped.

[0045] In specific implementation, the arc opening directions of the clamping plates 903 on the upper and lower sides are opposite to each other, clamping the patient's arm in the middle, and the second spring 902 is compressed and reset to give force to the clamping plate 903 to clamp the patient's arm. In specific installation, one end of the second spring 902 is fixedly connected to the clamping plate 903, and the other end is fixedly connected to the fixing ring 9.

[0046] In order to prevent the patient's arm from being improperly placed during surgery or recuperation and affecting the accuracy of monitoring, in this embodiment, Figure 1 As shown, a support assembly is fixedly provided at the bottom of the fixed tube 1 , and the support assembly includes a mounting sleeve 10 fixedly sleeved on the outer side wall of the fixed tube 1 , and an L-shaped support leg 1001 fixedly provided on the mounting sleeve 10 .

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
