Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent monitoring device for neonatal abdominal pressure. Background Art

[0002] Newborns, especially premature infants, are at high risk for neonatal necrotizing enterocolitis (NEC) and feeding intolerance (FI). Neonatal necrotizing enterocolitis is severe and rapidly progressive, requiring some patients to undergo surgical intervention, such as bowel resection or enterostomy. Even with surgical intervention, extensive necrotizing bowel or complications such as sepsis and disseminated intravascular coagulation (DIC) can lead to delayed surgery or even death. Survivors may also experience serious adverse outcomes such as short bowel syndrome, growth restriction, and impaired neurological development, which can negatively impact their quality of life. Statistics show that the incidence of NEC in live births ranges from 0.5‰ to 5‰, accounting for 2% to 5% of NICU admissions, but the mortality rate is 23% to 30%. Early detection and diagnosis of neonatal necrotizing enterocolitis and prompt treatment can alleviate the severity and duration of the disease, reduce the need for surgery, and minimize the risk of sequelae and mortality.

[0003] The early clinical manifestations of the disease are often atypical, mainly including abdominal distension, vomiting, bloody stools, weakened or absent bowel sounds, and associated symptoms of infection. Abdominal distension may usually be the first symptom, and because the lesion is intestinal necrosis in the abdominal cavity, it will inevitably cause changes in abdominal tension. However, since it is impossible for medical staff to continuously check or examine the child, in clinical diagnosis, most of the time, the patrol nurse discovers the child's abdominal distension or other symptoms, then notifies the clinician, and then confirms the diagnosis through further physical examination and laboratory tests. This usually happens when NEC has entered the progressive process. How to detect and identify the disease early is particularly important. Because these children often have abdominal distension symptoms, and it is usually an early-onset symptom, this discovery continuously monitors changes in abdominal pressure, intelligently analyzes pressure abnormalities, and promptly reminds appropriate clinical interventions to reduce the severity of the disease, reduce mortality and disability rates, and improve the prognosis of children. Summary of the Invention

[0004] The purpose of the present invention is to provide a newborn abdominal pressure intelligent monitoring device that can monitor the newborn abdominal pressure in real time, so as to detect newborn symptoms as early as possible and improve the efficiency and success rate of diagnosis and treatment.

[0005] Based on the above purpose, the present invention adopts the following technical solutions: A device for intelligently monitoring abdominal pressure in newborns comprises a rotating body-shaped shell, the interior of the shell being vertically hollow, and a ring-shaped adhesive patch being coaxially fixedly connected to the bottom edge of the shell; a top cover being provided on the top of the shell, and a pressure sensor being fixedly connected below the top cover; a spring being fixedly connected below the pressure sensor, the spring being arranged vertically, and a marble being fixedly connected to the end of the spring; the marble being coaxially arranged with the shell, and an electronic stethoscope being provided inside the marble.

[0006] Preferably, the electronic stethoscope includes a film, which is fixed to the bottom end of the marble through a bottom cover; a sound tube is provided on the top of the film, and a sound transmission channel is provided inside the sound tube; and an acoustic-electric converter is connected to the top of the sound tube.

[0007] Preferably, a buffer pad is sandwiched between the top of the sound tube and the acoustic-electric converter, and an inner lining pad is provided on the inner wall of the sound transmission channel.

[0008] Preferably, a pressure plate is fixedly provided at the bottom of the pressure sensor, and the top end of the spring is fixedly connected to the pressure plate.

[0009] Preferably, a positioning rod is provided on the bottom surface of the top cover, and the positioning rod is vertically arranged; and positioning holes that cooperate with the positioning rod are provided on the pressure sensor and the pin.

[0010] Preferably, a convex edge is provided on the outer side surface of the top of the shell, and a fixing through hole is provided on the convex edge; the fixing through hole is arranged horizontally, and a fixing screw hole matching the fixing through hole is provided on the top cover; the top cover is fixedly connected to the shell by screws.

[0011] Preferably, the electronic stethoscope and the pressure sensor are both connected to the monitoring terminal via a connecting line.

[0012] Preferably, a battery compartment is fixedly provided on the top of the top cover, and the battery compartment is connected to the electronic stethoscope and the pressure sensor respectively through power supply lines.

[0013] Preferably, a display screen is provided on the top of the battery compartment, the display screen is connected to the battery compartment via a power supply line, and the electronic stethoscope and the pressure sensor are both connected to the display screen via signal lines.

[0014] The beneficial effects of the present invention are: The present invention can be directly attached to the patient's body surface and continuously and dynamically monitor the patient's abdominal pressure, solving the traditional problem of being unable to continuously monitor the abdominal pressure of newborns. By continuously monitoring the abdominal pressure of newborns, the ability to identify diseases early, diagnose and treat them early is greatly improved, which can significantly reduce the extent and number of severe cases, reduce the mortality and disability rates of related diseases, and improve the quality of life of the population.

[0015] In addition to being able to monitor the patient's abdominal pressure, the present invention can also monitor the patient's bowel sounds in real time through a built-in electronic stethoscope. Through the dual monitoring of abdominal pressure and bowel sounds, the diagnostic accuracy of related diseases can be further improved, and the occurrence and development of diseases that may cause changes in abdominal pressure and bowel sounds, such as various types of intestinal obstruction, peritonitis, and abdominal surgery, can be discovered in a timely manner. It can also expand the scope of application, dynamically monitor the abdominal pressure and bowel sound changes of infants and young children at different ages, and expand the cognition and understanding of the development or physiological changes of the gastrointestinal tract of premature infants, newborns, and infants.

[0016] The present invention is compact in size and light in weight. It is attached to the patient's body surface through an adhesive patch and can withstand simple activities, crying, turning over and other movements of newborns and infants, and is not easy to fall off. The spring continuously adds pressure to the marble and is limited by the positioning rod, so that it can adapt to various postures of the patient and can maintain normal operation even when the abdomen is not in an upward posture. It is connected to the upper monitoring end through a wired or wireless connection, and the monitoring data is transmitted to the monitoring end for recording. By recording and arranging the patient's abdominal pressure and bowel sound data trends for a long time, the influence of short-term movements, breathing and the like is eliminated, and symptoms are discovered in a timely and accurate manner.

DETAILED DESCRIPTION

[0019] Example 1 The following is a further explanation of the present invention with reference to specific embodiments. Figure 1As shown, this embodiment is an intelligent abdominal pressure monitoring device for neonates, which is mainly used to monitor the abdominal pressure and bowel sounds of neonates, and includes a shell 1; the shell 1 is a rotating body structure, its interior is hollow, and a ring-shaped adhesive sheet 11 is provided at the bottom; an adhesive is provided on the bottom surface of the adhesive sheet 11, and the device can be adhered to the patient's body surface for fixation.

[0020] like Figure 2 and Figure 3 As shown, a circle of convex edge 12 is provided on the outer side surface of the top of the shell 1, and the convex edge 12 protrudes from the outer side surface of the shell 1, making it easier to stick and remove the device; a top cover 2 is provided on the inner side of the top of the shell 1, and a positioning groove 21 is provided on the side of the top cover 2, which is used to cooperate with the protrusion on the inner side of the top of the shell 1 to position the installation angle of the top cover; a pair of positioning through holes 13 are provided on the side of the convex edge 12, and a pair of positioning screw holes are provided on the side of the top cover 2 to cooperate with it; when the positioning through holes 13 are aligned with the positioning screw holes, the top cover 2 can be fixed to the top of the shell 1 by screws 14.

[0021] like Figure 4 As shown, a pressure sensor 5 is fixedly provided on the bottom surface of the top cover 2, and a pressure plate is provided on the bottom surface of the pressure sensor 5, and a spring 6 is fixedly connected to the bottom surface of the pressure plate; the spring 6 is a vertically arranged compression spring, and when the spring 6 is compressed by pressure, the pressure can be transmitted to the pressure sensor 5 through the pressure plate and a corresponding electrical signal is generated; a ball 4 is fixedly connected to the bottom of the spring 6, and the ball 4 is a hollow rotating body structure coaxially arranged with the shell 1; a positioning rod 22 is also provided on the bottom surface of the top cover 2, and in this embodiment, a pair of positioning rods 22 are symmetrically provided; in coordination with this, a pair of positioning rods 22 are provided on the top surfaces of the pressure sensor 5 and the ball 4. A positioning hole 51 is provided to cooperate with it; a quick-release buckle (not shown in the figure) is provided on the positioning rod 22 to cooperate with the pressure sensor 5, and the pressure sensor 5 can be fixed between the quick-release buckle and the top cover 2; and through the positioning rod 22 and the positioning hole 51, the movement of the ball 4 can be limited so that it can only perform telescopic movement in the vertical direction, thereby ensuring that the value received by the pressure sensor is accurate; in the natural state, the bottom end of the ball 4 is set beyond the bottom end of the shell 1, and when the device is installed on the patient, the bottom surface of the ball 4 and the bottom surface of the shell 1 are in contact with the patient's body surface, and the spring 6 is always subjected to inward pressure to compress it.

[0022] An electronic stethoscope structure is provided inside the ball 4, including a film 42 provided at the bottom of the ball 4; the bottom of the ball 4 is provided with an opening, and the film 42 is fixed at the bottom through a bottom cover 43; the middle part of the bottom cover 43 is provided with a through hole, so that the film 42 can be directly attached to the patient's body surface to collect the patient's bowel sounds; a sound receiving tube 41 is provided on the top of the film 42, and the sound receiving tube 41 includes a truncated cone-shaped lower half and a cylindrical upper half, and a sound transmission channel 45 is provided in the sound receiving tube 41, which can transmit the sound emitted by the vibration of the film upward through the sound transmission channel 45; an acoustic-to-electric converter 44 is connected to the top of the sound receiving tube 41 through a cushioning pad made of various materials, and the acoustic-to-electric converter 44 can generate a corresponding electrical signal after receiving the sound transmitted through the sound transmission channel 45; an inner lining is provided on the inner wall of the sound transmission channel 45, and the inner wall of the inner lining is smooth, which can avoid the gap at the connection of the multi-layer cushioning pads causing bowel sounds to generate noise during the transmission process, thereby improving the sound reception quality.

[0023] like Figure 2 As shown, this embodiment is a wired connection, and a wire outlet 15 is provided on the side of the housing 1; the power line and data line of the pressure sensor 5 and the electronic stethoscope can be extended through the wire outlet 15 and connected to the external monitoring end to maintain power supply and transmit the obtained electrical signal to the monitoring end; the monitoring end can obtain the patient's abdominal pressure and bowel sound data through the electrical signal transmitted by the analysis device.

[0024] When this embodiment is actually used, it only needs to be directly attached to the patient's abdomen through the adhesive patch 11; under the action of the spring 6, the ball 4 always keeps the bottom end close to the patient's body surface, so that the film 42 remains in contact with the patient's abdominal skin; the patient's bowel sounds can be collected by the electronic stethoscope and transmitted to the monitoring end; and because the spring 6 always remains in a compressed and contracted state during use, it will apply a pressure to the pressure plate; this pressure will change according to the patient's abdominal pressure, and the pressure sensor 5 collects and converts the pressure data into an electrical signal and transmits it to the monitoring end. The monitoring end can identify the patient's abnormal abdominal pressure signal by recording the pressure change trend; combined with the bowel sound data, the patient's condition can be diagnosed promptly and quickly, thereby seizing the precious early treatment time.

[0025] Example 2 The difference between this embodiment and embodiment 1 is that this embodiment no longer adopts the form of wired connection to the monitoring terminal, but instead provides a display screen 7 on the top of the top cover 2, and displays the patient's abdominal pressure data in real time through the display screen 7.

[0026] A battery compartment 71 is fixedly provided on the top of the top cover 2, and the battery compartment 71 supplies power to the display screen 7, the pressure sensor 5 and the electronic stethoscope respectively; the data obtained by the pressure sensor 5 and the electronic stethoscope are directly input into the PLC built into the display screen 7, and converted into visual data for display on the display screen 7; the PLC is preset with an abnormal monitoring program, and when the patient's abdominal pressure and bowel sound data are abnormal, an alarm can be sounded through the speaker hole 72, prompting medical staff to check and diagnose in time; a wireless connection module can also be set in the PLC, and its data can be connected to the monitoring end via a wireless connection, and the monitoring data can be synchronized in real time at the monitoring end; the wireless connection can eliminate the connecting wires, thereby avoiding the risk of newborns and infants being injured by entanglement or binding of the connecting wires.
