Description

Technical Field

[0001] This utility model relates to the field of jaundice measurement technology, and more specifically, to a transcutaneous jaundice measurement device. Background Technology

[0002] Bilirubin accumulates in blood, tissues, and interstitial fluid, causing yellowing of the skin, mucous membranes, sclera, and certain body fluids, clinically known as jaundice. Neonatal hyperbilirubinemia is a common disease in the neonatal period, and in severe cases, it can lead to kernicterus and bilirubin-induced brain disorders. Therefore, dynamic observation of neonatal jaundice is necessary in clinical practice for timely detection and treatment. Traditional serum tests can accurately measure the levels of total bilirubin and direct bilirubin in serum, but they require blood collection, causing some discomfort to the infant and are inconvenient for repeated testing. Transcutaneous bilirubinometers, on the other hand, have the advantages of being quick and non-invasive, facilitating dynamic observation, and have wide applications.

[0003] In existing technologies, transcutaneous jaundice meters measure jaundice by pressing a probe to emit light. To improve measurement accuracy, the area around the probe needs to be manually covered to prevent light leakage from affecting accuracy. Furthermore, when measuring the forehead, it's crucial to prevent light leakage from shining into the infant's eyes and causing harm, thus preventing discomfort and movement during the measurement process that could affect accuracy. How to invent a transcutaneous jaundice meter that solves these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a transcutaneous jaundice meter, which aims to solve the problem that in the transcutaneous jaundice meter, the area around the probe needs to be manually covered to avoid light leakage affecting the measurement accuracy when the light emitted during the measurement process is generated by pressing the probe.

[0005] This utility model is implemented as follows: This utility model provides a transcutaneous jaundice meter, including an instrument body and a fixing ring disposed on one side of the instrument body, wherein a probe is installed at one end of the instrument body; The fixing ring is installed on the outside of the probe. Multiple adjusting springs are installed at one end of the fixing ring, and adjusting rings are installed at one end of each adjusting spring. A silicone ring is installed on the inner wall of one end of the adjusting ring.

[0006] Preferably, the probe and the inner wall of one end of the instrument body are slidably connected, a threaded strip is provided on the outer side of the probe, and the inner wall of the fixing ring is fixed to the outer wall of the probe by the threaded strip.

[0007] Preferably, the two end sidewalls of the adjusting spring are fixedly connected to one end of the fixed ring and the adjusting ring, respectively, and the inner wall of the adjusting ring is slidably connected to the outer wall of the probe.

[0008] Preferably, one end of the adjusting ring is fixedly connected to one end of the silicone ring, the surface of the silicone ring is coated with a brown coating, and one end of the silicone ring is fixedly connected to an annular airbag.

[0009] Preferably, a plurality of piston sleeves are fixedly connected to one end of the adjusting ring near the adjusting spring, and the surface of the adjusting ring has through holes aligned with the internal holes of the piston sleeves.

[0010] Preferably, a plurality of piston rods are fixedly connected to one end of the fixing ring near the piston sleeve, and a piston plate is fixedly connected to one end of the piston rod. The outer wall of the piston plate is piston-connected to the inner wall of the piston sleeve.

[0011] The beneficial effects of this utility model are: During the pressing of the probe, the annular airbag is compressed and deformed, allowing its outer surface to better conform to the baby's skin. This effectively blocks external light from entering through the edge gaps and better covers areas around the skin that may leak light, ensuring the darkness of the measurement environment and thus improving measurement accuracy. At the same time, the annular airbag can evenly distribute pressure on the contact area, avoiding excessive local pressure that could damage the baby's skin, thereby improving the baby's comfort during the testing process. Additionally, the soft silicone ring at one end of the annular airbag, together with the annular airbag, can reduce the squeezing sensation felt by the baby during the measurement process, further improving the comfort of the measurement process. Simultaneously, the piston sleeve, in conjunction with the piston rod, pushes the air inside the piston sleeve to flow outward during the pressing and measurement process. This allows the air to blow out through the hole at one end onto the baby's skin, providing a cooling sensation and relieving the stuffiness caused by pressing and skin contact. This makes the baby feel more comfortable, reducing crying and struggling caused by discomfort, making the measurement process smoother, and ensuring the accuracy of subsequent measurements.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example, refer to Figures 1-4 A transcutaneous jaundice device includes an instrument body 1 and a fixing ring 2 disposed on one side of the instrument body 1, characterized in that a probe 11 is installed at one end of the instrument body 1; The fixing ring 2 is installed on the outside of the probe 11. Multiple adjusting springs 21 are installed on one end of the fixing ring 2. An adjusting ring 22 is installed on one end of the adjusting spring 21. A silicone ring 23 is installed on the inner wall of one end of the adjusting ring 22.

[0017] Furthermore, the probe 11 is slidably connected to the inner wall of one end of the instrument body 1, and a threaded strip 12 is provided on the outer side of the probe 11. The inner wall of the fixing ring 2 is threadedly fixed to the outer wall of the probe 11 through the threaded strip 12. The two side walls of the adjusting spring 21 are respectively fixedly connected to one end of the fixing ring 2 and the adjusting ring 22. The inner wall of the adjusting ring 22 is slidably connected to the outer wall of the probe 11. The inner wall of one end of the adjusting ring 22 is fixedly connected to one end of the silicone ring 23. The surface of the silicone ring 23 is coated with a brown coating. An annular airbag 24 is fixedly connected to one end of the silicone ring 23.

[0018] It should be noted that when using the instrument to detect jaundice in an infant, the device is held perpendicular to the infant's skin, with the annular airbag 24 not fully inflated, ensuring one end of the annular airbag 24 is in close contact with the infant's skin. Then, the instrument body 1 is pressed downwards. During this process, the instrument body 1 and the probe 11 move simultaneously with the outer fixing ring 2, and the position of the adjusting ring 22 remains unchanged under the action of the adjusting spring 21, until the probe 11 contacts the infant's skin. Then, during the downward movement, the probe 11 is compressed and extends into the interior of the instrument body 1, continuing the detection until the position of the probe 11 remains fixed. Throughout this process, the annular airbag 24 remains in close contact with the infant's skin, and the annular airbag 24 is squeezed during the pressing of the probe 11. The deformation allows its outer surface to better conform to the baby's skin, effectively blocking external light from entering through the edge gaps. It can better cover areas near the skin that may leak light, ensuring the darkness of the measurement environment and thus improving measurement accuracy. At the same time, the annular airbag 24 can evenly distribute pressure on the contact area, avoiding excessive local pressure that could damage the baby's skin, thereby improving the baby's comfort during the testing process. Meanwhile, the soft silicone ring 23 at one end of the annular airbag 24 has a certain cushioning performance, which, together with the annular airbag 24, can further reduce the impact on the baby's skin when pressed, reducing the squeezing sensation felt by the baby during the measurement process, thereby further improving the comfort of the measurement process.

[0019] Furthermore, multiple piston sleeves 221 are fixedly connected to one end of the adjusting ring 22 near the adjusting spring 21. The surface of the adjusting ring 22 has through holes aligned with the internal holes of the piston sleeves 221. Multiple piston rods 25 are fixedly connected to one end of the fixing ring 2 near the piston sleeves 221. A piston plate 251 is fixedly connected to one end of the piston rod 25. The outer wall of the piston plate 251 is piston-connected to the inner wall of the piston sleeve 221.

[0020] It should be noted that during the pressure measurement process, as the annular airbag 24 contacts the probe 11 and then the infant's skin, the downward pressure of the probe 11 causes the outer fixing ring 2 to move, while the position of the adjusting ring 22 remains fixed. During this process, multiple piston rods 25 at one end of the fixing ring 2 drive the piston plate 251 at one end to move towards the skin side within the piston sleeve 221. In this process, the piston plate 251 pushes the air inside the piston sleeve 221 to flow outward, allowing air to blow onto the infant's skin through the hole at one end. This provides a cooling sensation to the infant, relieving the stuffiness caused by pressure and skin contact, making the infant feel more comfortable, thus reducing crying and struggling caused by discomfort, making the measurement process smoother, and ensuring the accuracy of subsequent measurements.

[0021] The working principle of this transcutaneous jaundice meter: When performing jaundice detection on an infant using the instrument, the device is held perpendicular to the infant's skin. The annular air bladder 24 is not fully inflated, so that one end of the annular air bladder 24 is pressed tightly against the infant's skin. Then, the instrument body 1 is pressed down. During this process, the instrument body 1 and the probe 11 move simultaneously with the outer fixing ring 2, and the position of the adjusting ring 22 is kept unchanged by the action of the adjusting spring 21 until the probe 11 contacts the infant's skin. Then, during the downward movement, the probe 11 is compressed and extends into the interior of the instrument body 1, and the detection continues until the probe 11 retracts to its end position and remains fixed, thus completing one detection. During this process, the annular air bladder 24 remains in close contact with the infant's skin, and the annular air bladder 24 is squeezed during the pressing of the probe 11. The pressure causes deformation, allowing its outer surface to better conform to the baby's skin. This effectively blocks external light from entering through edge gaps and better covers areas near the skin where light might leak, ensuring a dark measurement environment and improving measurement accuracy. Simultaneously, the annular airbag 24 distributes pressure evenly across the contact area, preventing excessive local pressure from damaging the baby's skin and improving comfort during the measurement process. Furthermore, the soft silicone ring 23 at one end of the annular airbag 24 provides cushioning, further reducing impact on the baby's skin during pressure and minimizing the squeezing sensation, thus further enhancing comfort.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
