[0002] In recent years, medical staff have generally used oral pressure measuring devices to measure the user's oral muscle pressure, thereby helping them to evaluate and conduct rehabilitation training for patients with oral and maxillofacial dysfunction. In order to accurately evaluate the user's oral and maxillofacial functions such as sucking, swallowing and pronunciation, the requirements for the accuracy of oral pressure measuring devices are becoming increasingly higher.

[0003] At present, in the oral pressure measuring device, the air bag is connected to the air pressure measuring device through a slender catheter. When the user's oral muscles squeeze the air bag, the air pressure is measured by the air pressure measuring device to determine the oral pressure. However, friction occurs during the transmission of the gas in the catheter, causing gas loss, resulting in low measurement accuracy of the oral pressure. In addition, the catheter is prone to aging or deformation. When the size or structure of the catheter changes, the measurement accuracy of the oral pressure is low. Summary of the invention

In addition, the oral pressure measuring device has a simple structure and a simple production process.

[0032] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

The air pressure detection component 300 can accurately detect the air pressure in the airbag component 200, and the measurement accuracy of the oral pressure is high.

[0040] It can be understood that by setting the first handle body 110 and the second handle body 120, the air pressure detection assembly 300 is fixed on the first handle body 110, and the user holds the oral pressure measuring device through the second handle body 120. During normal use of the oral pressure measuring device, the user will not touch the air pressure detection assembly 300, which can effectively protect the air pressure detection assembly 300 and increase the reliability of the handle assembly 100. The first handle body 110 and the second handle body 120 are detachably connected, which is convenient for replacement of components and has high practicality.

[0041] It should be noted that the air pressure detection component 300 is fixed on the first handle body 110, which means that the air pressure detection component 300 is fixed on the end surface of the first handle body 110, and has high stability.

[0045] In some embodiments of the oral pressure measurement device, the thickness of the flexible air pressure sensor 310 is less than 450 microns, the cross-sectional area of ​​the flexible air pressure sensor 310 is less than 5.5 square millimeters, and the measuring range of the flexible air pressure sensor 310 is less than 100 kPa.

[0046] It can be understood that the size of the flexible air pressure sensor 310 is limited to ensure that the flexible air pressure sensor 310 extends into the airbag assembly 200 and is resistant to bending; in addition, by adjusting the range of the flexible air pressure sensor 310, the flexible air pressure sensor 310 can adapt to airbag assemblies 200 of different specifications. The range adjustment method of the flexible air pressure sensor 310 includes but is not limited to: cascading sensing units, and adjusting the pressure difference between the inside and outside of the second sealed cavity 314 during vacuum pressing.

When the connecting member 220 and the first handle body 110 are in a connected state, the sealing gasket 420 fits tightly with the connecting member 220, thereby ensuring a sealed connection between the first handle body 110 and the connecting member 220, thereby ensuring the airtightness of the flexible airbag 210; in addition, the connecting member 220 and the first handle body 110 are detachably connected, which can facilitate the replacement of parts and improve work efficiency.

[0050] It should be noted that the materials used to make the flexible airbag 210 include, but are not limited to, polyvinyl chloride, rubber, and silicone.

[0051] In some embodiments of the oral pressure measurement device, a sealant 410 is provided between the air pressure detection component 300 and the sealing gasket 420, and the air pressure detection component 300 and the sealing gasket 420 are sealed and connected by the sealant 410, for example Figure 4 and Figure 5 As shown in the oral pressure measurement device provided in.

[0052] It can be understood that by providing the sealant 410, the sealing between the air pressure detection component 300 and the sealing gasket 420 can be ensured, the production process is simple, and the manufacturing cost is low.

[0053] In some embodiments of the oral pressure measurement device, the first through hole 101 penetrates the first handle body 110 and the second handle body 120, the inner wall of the first handle body 110 close to the second handle body 120 is provided with a first thread 510, the outer wall of the second handle body 120 close to the first handle body 110 is provided with a second thread 520, the first thread 510 matches the second thread 520, the second through hole 221 is provided with a third thread 530, the outer wall of the first handle body 110 away from the second handle body 120 is provided with a fourth thread 540, the third thread 530 matches the fourth thread 540, for example Figure 5 As shown in the oral pressure measurement device provided in.

[0054] It can be understood that the first handle body 110 and the second handle body 120 are connected by threads. By fixing the first handle body 110 and rotating the second handle body 120, the first handle body 110 and the second handle body 120 can be disassembled and assembled, which is simple to disassemble and assemble, which is convenient for disassembly and assembly and debugging of the air pressure detection component 300, and makes the connection between the first handle body 110 and the second handle body 120 more secure; the connecting piece 220 and the first handle body 110 are connected by threads. By fixing the connecting piece 220 and rotating the first handle body 110, the connecting piece 220 and the first handle body 110 can be disassembled and assembled, which is simple to disassemble and assemble, which is convenient for disassembly and assembly and debugging of the air pressure detection component 300, and makes the connection between the connecting piece 220 and the first handle body 110 more secure.

[0055] It should be noted that the first thread 510 is disposed in the first through hole 101 of the first handle body 110 , and the lead-in procedure of the first wire 301 is simple.

[0056] In some embodiments of the oral pressure measurement device, the outer diameter of the sealing pad 420 is equal to the diameter of the second through hole 221. Figures 2 to 4 As shown in the oral pressure measurement device provided in.

[0057] It is understandable that the outer diameter of the sealing gasket 420 is limited, and when the connecting member 220 and the first handle body 110 are in a connected state, the sealing gasket 420 and the second through hole 221 are tightly fitted, which can ensure the airtightness of the airbag assembly 200.

[0058] In some embodiments of the oral pressure measuring device, a first rotary head 111 is disposed at one end of the first handle body 110 close to the second handle body 120, and a second rotary head 121 is disposed at one end of the second handle body 120 away from the first handle body 110, for example Figure 1 and Figure 2 As shown in the oral pressure measurement device provided in.

[0059] It can be understood that the first screw head 111 and the second screw head 121 have the same shape and structure, and are both composed of a plurality of convex ribs, and the plurality of convex ribs are evenly distributed around the first handle body 110 or the second handle body 120, and the convex ribs are provided with teeth, and the teeth are used to increase friction. By setting the first screw head 111 and the second screw head 121, the disassembly and assembly of the first screw head 111 and the second screw head 121 can be facilitated.

[0060] In some embodiments of the oral pressure measurement device, the first handle body 110 and the second handle body 120 are in the shape of a hollow cylinder, and the central axis of the first handle body 110 coincides with the central axis of the second handle body 120. Figure 1 and Figure 2 As shown in the oral pressure measurement device provided in.

[0061] It can be understood that the shapes of the first handle body 110 and the second handle body 120 are defined, and the relative positions of the first handle body 110 and the second handle body 120 are defined. Since the central axis of the first handle body 110 and the central axis of the second handle body 120 coincide with each other, it is equivalent to that the first handle body 110 and the second handle body 120 are located on the same straight line, which facilitates the lead-in of the first wire 301.

[0062] In addition, refer to Figure 7 , Figure 7 It is a schematic diagram of a response curve of an air pressure detection component 300 provided in another embodiment of the present invention.

[0063] It can be understood that when the user's oral muscles squeeze the airbag assembly 200, the air pressure in the first sealed cavity 201 will change, and the resistance change rate of the air pressure detection assembly 300 will decrease. When the airbag assembly 200 is not squeezed, the resistance change rate of the air pressure detection assembly 300 returns to the initial value; when different pressures are applied to the airbag assembly 200, the electrical signal of the air pressure detection assembly 300 will change accordingly.

[0064] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
