The suction testing device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1, in a first aspect of an embodiment of the present application, there is provided a suction testing device, which may include: the nipple 100, the hose 200, the flow sensor 300, the liquid storage container 400, the pressure sensor 500 and the hand grip 600;
The hand grip 600 is provided with a cylindrical support frame 610, the pressure sensor 500 is annular, and the pressure sensor 500 is sleeved on the circumferential side of the cylindrical support frame 610;
The silica gel nipple 100 is provided with a first connecting part 110, and the hand grip 600 is provided with a second connecting part 620; the silica gel nipple 100 is sleeved outside the cylindrical supporting frame 610, and is connected with the hand grip 600 through the cooperation of the first connecting portion 110 and the second connecting portion 620;
the silica gel nipple 100 is provided with a sucking hole, and the sucking hole is communicated with the inner cavity of the liquid storage container 400 through the hose 200 and the flow sensor 300.
The oromandibular system is a complex motor biological system, and the contraction of the perioral muscles is not only the motive force that creates various oral pressures, but the labial, buccal and lingual muscle activities themselves also exert pressure on the dental jaw, i.e., perioral pressure. Intra-oral pressure refers to the negative pressure of the oral contents, which is generated by the contraction of the oral muscles and the movement of the mandible, due to the squeezing of the oral contents and the suction of air, and is positively correlated with the sucking force.
In the embodiment, the flow sensor 300 is used for measuring the flow rate and flow rate of the liquid sucked by the infant, and the negative pressure in the oral cavity can be obtained through calculation; in addition, because infant's lip closure ability is closely related with sucking power, only closure ability is stronger, is difficult for the gas leakage more, and sucking power is also stronger, and the nipple is usually circular in reality, has added annular pressure sensor in this embodiment, directly laminates with the nipple for measure lip closure ability.
According to the device, the pressure sensor 500 and the flow sensor 300 are combined through the silica gel nipple 100, so that the extrusion force of lip closing and the negative pressure in the oral cavity are measured, and objective and accurate measurement of sucking force is realized; therefore, the development and health condition of the whole body and the local oral cavity of the infant individual can be judged according to the measurement result.
The first connection part 110 and the second connection part 620 in this embodiment may be engaged with each other by a snap fit, a screw thread engaged with each other, or a bolt and a nut engaged with each other, so long as the nipple 100 and the hand grip 600 can be fixed.
In some embodiments, the cylindrical support 610 is provided with a miniature wide angle camera 700 near the end of the silica gel nipple 100;
The silica gel nipple 100 is made of high-permeability silica gel.
The sucking ability is a complex combination of movements, and changes in the sucking ability are caused by perilabial forces, tongue packing ability, cheek muscle forces and mandibular movements. Therefore, the micro wide-angle camera 700 of the present embodiment is used to observe the oral cavity activity and feeding skill of the infant, and further determine the sucking force.
Specifically, the miniature wide-angle camera 700 can adopt a fish-eye structure camera, and the visual angle range can reach 120 degrees, so that more environments in the oral cavity can be captured. In addition, the camera can adopt an infrared camera, in the detection process, transparent test liquid can be added into the liquid storage container 400, and the transparent test liquid is easily captured by the infrared camera through the difference between the liquid temperature and the body surface temperature, so that the whole muscle action in the swallowing action is analyzed.
More specifically, since the peak wavelength of liquid fluorescence is 290nm, and f=c/λ, f=3×108/290×10 -9, the spectral frequency is: 1.03 x 10 15 Hz. Based on this spectral frequency, the image can be corrected.
In some embodiments, the miniature wide angle camera 700 is provided with a light source on the perimeter side.
The lips close during sucking and the internal environment of the mouth is relatively dark, thus requiring an additional auxiliary light source.
As shown in fig. 2, in some embodiments, the plurality of light sources are disposed uniformly around the miniature wide-angle camera 700.
The surrounding arrangement of the light source can avoid unclear observation caused by the shielding of the tongue
In some embodiments, the light source is an infrared LED lamp.
The light of the infrared LED lamp is invisible light, so that eyes of children are not hurt.
In some embodiments, the suction testing device further comprises: a data receiver 800;
The data receiver 800 is connected to the miniature wide-angle camera 700, the flow sensor 300, and the pressure sensor 500, respectively.
In this embodiment, the data receiver 800 may be connected to the micro wide-angle camera 700, the flow sensor 300, and the pressure sensor 500 by bluetooth, wifi, or a data line 900, respectively.
Preferably, the data receiver 800 may be connected to the micro wide-angle camera 700, the flow sensor 300 and the pressure sensor 500 through data lines 900, respectively. This reduces the effect of radiation on the infant.
In some embodiments, the data receiver 800 is provided with a display screen for displaying the test fluid flow and lip closure pressure in real time.
Specifically, the data receiver 800 may adopt an STM32F4 series microprocessor, and connect interactive data with the micro wide-angle camera 700, the flow sensor 300 and the pressure sensor 500 through a USB port, where the data receiver 800 may output an image to a display screen, both the flow sensor 300 and the pressure sensor 500 access an AD pin of the microprocessor, and convert an analog quantity into a digital quantity through an AD conversion in the processor, so as to obtain real-time flow and pressure, and the AD conversion can reach 12-bit precision.
In some embodiments, the diameter of the pressure sensor 500 satisfies the following equation:
98％D≤d＜D
Where d is the diameter of pressure sensor 500; d is the inner diameter of the silicone nipple 100.
The diameter of the pressure sensor 500 is slightly smaller than the inner diameter of the silicone nipple 100, so that even if the lips are gently closed, detection of the closing force is more accurate.
In some embodiments, the hand grip 600 is provided with a lead-out hole for the silicone hose 200;
The guide-out hole is used for restraining the silica gel hose 200.
The guiding-out hole of the present embodiment prevents the flexible tube 200 from being caught by the infant, affecting the accuracy of the detection.
In some embodiments, the first connection portion 110 and the second connection portion 620 are snap-fit to each other;
The first connecting portion 110 is clamped with the second connecting portion 620, so that the silica gel nipple 100 is fixed with the hand grip 600.
Furthermore, comfort is critical in the design of infant sucking test devices. The infant's skin is delicate, so it is necessary to ensure that the parts of the device that come into contact with the infant are soft, harmless and ergonomic. The silicone nipple 100 is medical grade silicone to ensure that it is non-irritating to the infant's skin. The silica gel nipple 100 is designed to be in a shape fitting with the oral cavity structure of the infant, so that the fitting degree of the silica gel nipple with the oral cavity of the infant is ensured to be high, and uncomfortable feeling is reduced. And the edge of the silicone nipple 100 is smoothed to ensure smooth edges of the device, avoiding irritation to the infant's skin, especially when used for a long period of time.
The hand grip 600 is a natural material. Illustratively, the hand grip is natural rubber or organic cotton to reduce exposure to chemical components and reduce risk of allergies. Natural materials are generally softer, more breathable, milder to the skin of the infant, and may provide a more comfortable use experience.
The flow sensor 300 and the liquid storage container 400 are designed with waterproof function to ensure durability and safety of the device. In the material selection and structural design of the device, waterproof materials and sealing structures are adopted to prevent liquid from penetrating into the device, and cleaning and disinfection are easy.
The embodiments of the present application have been described above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present application and the scope of the claims, which are to be protected by the present application.
