Description

Technical Field

[0001] The invention belongs to the field of medical equipment, and in particular relates to a multifunctional probe of a B-ultrasound or fetal heart monitor. Background Art

[0002] With the emergence of assisted reproductive technology, the reproductive problems of most infertile families in today's society have been solved, but at the same time, the consumption of clinical resources and the difficulty of fetal intrauterine monitoring have increased. Among them, the perinatal mortality rate of twin pregnancy is significantly higher than that of single pregnancy, and the incidence of intrauterine death of one of the twins is 2-6%. Intrauterine fetal death of one of the twins refers to a twin pregnancy that is confirmed in the early pregnancy, and ultrasound examination later indicates that one of the fetuses has died. The death of one of the twins can have potential effects on the mother and child. Timely and effective monitoring and intervention during pregnancy are the key to improving the prognosis of the mother and child.

[0003] Electronic fetal heart rate monitoring is a means of assessing the intrauterine status of the fetus. Its main purpose is to detect fetal intrauterine hypoxia in time so that further measures can be taken in time. At present, electronic fetal heart rate monitoring is widely used in midwifery medical institutions at all levels across the country. Correct interpretation of fetal heart rate monitoring graphics has great clinical significance in reducing neonatal convulsions, cerebral palsy, perinatal mortality, and predicting neonatal acidosis, and can reduce unnecessary midwifery and cesarean section operations. The current structure of the electronic fetal heart rate monitor includes a host (laptop or desktop), a fetal heart rate probe (wired and wireless), a uterine pressure probe (wired and wireless), and a printer or paperless transmission to the host. The determination of the placement of the fetal heart rate probe of the electronic fetal heart rate monitor depends on the operator's skilled physical examination level in clinical practice. It will be affected by fetal peristalsis, changes in the pregnant woman's body position, loosening of the bandage, etc. Once a pregnant woman with obesity, polyhydramnios, etc., who has high uterine tension, cannot touch the fetal position, and is difficult to find the fetal heart, will take a long time to find and wear it. In addition, when twin or multiple pregnancies are undergoing fetal heart monitoring and the baseline curves are similar and difficult to distinguish, it is far from enough to judge the intrauterine fetal situation by physical examination alone, and the assistance of B-ultrasound is needed at this time. In addition, when the fetal heart baseline drops to 60-100 beats / min during the monitoring process, it is difficult to distinguish whether it is the pregnant woman's heart rate or the fetal heart rate, and the assistance of B-ultrasound is needed. Usually in clinical practice, when these situations occur, pregnant women are generally asked to do B-ultrasound or have a bedside B-ultrasound pushed over, but this often delays some time. If the intrauterine fetal situation is OK, you can wait for the arrival of the B-ultrasound machine, but once it involves emergency situations such as fetal distress and racing against time, pushing the B-ultrasound machine is often a waste of time. Therefore, this visual fetal heart monitoring probe with B-ultrasound function is feasible and valuable.

[0004] Although the electronic fetal heart rate monitors on the market have achieved paperless operation, images can be uploaded to the computer at any time, saving paper costs and labor time, and the uterine fundus and fetal heart rate probes have also achieved the transition from wired to ineffective. These changes have made electronic fetal heart rate monitors more convenient, but in the above situations, the assistance of B-ultrasound technology is still needed. The connection wires on clinical electronic fetal heart rate monitors are long and take up space, which increases the inconvenience of operation. Therefore, it is very necessary to design a retractable fetal heart rate probe with B-ultrasound probe function, and wired and wireless styles can be designed for clinical medical staff to choose. Summary of the invention

[0005] In view of the above-mentioned prior art, the purpose of the present invention is to provide a multifunctional probe.

[0006] The technical solution of the present invention is implemented as follows: a multifunctional probe includes a B-ultrasound probe, a fetal heart monitoring probe and a winding reel. The B-ultrasound probe and the fetal heart monitoring probe are fixed on both sides of a spherical shell so that the positions of the B-ultrasound probe and the fetal heart monitoring probe can be switched after the shell is rotated 180 degrees. The B-ultrasound probe and the fetal heart monitoring probe are provided with a data line and can be connected and disconnected with a B-ultrasound or fetal heart monitoring host by a switch on the shell. The data line can be wound or contracted on the winding reel and an interface is provided at the end of the data line for connection with the B-ultrasound or fetal heart monitoring host.

[0007] The beneficial effect of this design is to reduce the time for fetal heart monitoring for pregnant women with obesity, polyhydramnios, etc., which leads to high uterine tension, inability to touch the fetal position, and difficulty in finding the fetal heart, and save medical resources and labor costs. If the baseline curves are similar and difficult to distinguish when the pregnant woman is undergoing fetal heart monitoring for twin or multiple pregnancies, this design can quickly assist the doctor in judging the correctness of fetal heart monitoring and the intrauterine situation of the fetus. During the monitoring process, when the fetal heart baseline drops to 60-100 beats / min and it is difficult to distinguish whether it is the maternal heart rate or the fetal heart rate, this design can assist in identification, help to identify fetal distress early, and buy time for the prognosis of pregnant women and newborns. The design concept is scientific and practical. In line with the original intention of more effective and timely pregnancy detection and prevention of pregnancy outcomes such as intrauterine fetal death in twin and multiple pregnancies, the problem of long wearing time due to unclear fetal position caused by objective factors is solved, and the dilemma of difficult baseline identification of multiple fetuses and difficult maternal and fetal heart rate identification during fetal distress is dealt with in a timely and effective manner. It brings convenience to clinical operators, saves the cost of medical resources for subsequent vaginal B-ultrasound, and relieves the anxiety of pregnant women. The structure and function are harmonious, and the appearance is beautiful. It breaks the disadvantage of the traditional wired probe being too long. It adopts a telescopic storage line with a sleeve, which can adjust the length of the line according to the distance, reducing the floor space occupied by the line and the interference of the exposed line during operation. The interface of the probe adopts a common interface with the traditional one, which is convenient for better accommodating the advantages of traditional fetal heart monitoring. The whole is light and portable, and easy to operate. The retractable probe line greatly reduces the number and weight of the exposed wires, making the overall appearance of the fetal heart monitoring more neat and light, and also convenient to use.

[0008] Furthermore, a groove is provided on the cable winding reel which matches the protrusion on the shell so that the shell can be placed on the cable winding reel. The cable winding reel is provided with an elastic device which can automatically retract the data cable and a locking device so that the data cable can be locked after being pulled out to a certain length and automatically retracted by elastic potential energy after being unlocked. This design facilitates placement, reduces space occupation and makes placement more compact.

[0009] A multifunctional probe includes a base, a probe positioning seat and a probe. The probe is provided with a plurality of probes of different functional types and sizes, which are matched with corresponding probe positioning seats respectively so that different probes can be fixed to different probe positioning seats. The outer periphery of the probe positioning seat is designed the same to match the base. The base is provided with a fixing belt to fix the base to a certain position. With this design, different probes can be replaced at the same position. For example, after the B-ultrasound probe detects the position of the fetus, the fetal heart monitoring probe can be used for long-term monitoring. The base can be directly bound to a certain position of the human body, so that the positioning is very accurate and will not be displaced. Since there are many types of probes and different probes have different shapes and sizes, different probe positioning seats must be designed to match the probes in order to match the base, and then different probes can be completely fixed on the base.

[0010] Furthermore, a plurality of rotatable gear pumps are distributed inside the base along the outer circumference of the probe, the gear pump is provided with two side-by-side meshing conveying wheels, a driving wheel is provided below the conveying wheel, the conveying wheel and the driving wheel are both spur gears with the same modulus, the driving wheel is meshed with a conveying wheel close to one side of the probe so that the driving wheel can drive the conveying wheel to rotate, the driving wheel is hinged to the base and part of the gear teeth protrude from the base so that other objects contact the gear teeth and move in the plane of the base in the direction perpendicular to the center line of the gear, that is, the driving wheel can rotate relative to the base when it moves relative to the base, a certain gap is provided between the driving wheel teeth and the base so that the coupling agent can flow in the gap, the conveying wheel teeth and the base are closely matched so that the coupling agent will not leak, a coupling agent pipeline is provided above the conveying wheel so that the coupling agent can be delivered to the gear teeth, and the coupling agent pipeline is connected to the coupling agent pump so that the coupling agent can be delivered to the conveying wheel teeth through the coupling agent pump. This design does not require additional coupling agent to be added when using the probe, and the coupling agent can be continuously delivered by moving the base, and the coupling agent will only be released in the direction of the probe rotation, and the coupling agent will not be released behind the probe, so unnecessary waste will not be caused. In this design, the gear pump rotates in the forward direction in front of the probe, which can continuously deliver the coupling agent, and in the reverse direction behind the probe, the gear pump does not deliver the coupling agent. The gear pump on the side hardly rotates and does not deliver the coupling agent. This design uses a simple mechanical structure to achieve the output of the coupling agent in the correct position, which can be said to be a very sophisticated design.

[0011] Furthermore, a plurality of concentric annular coupling agent recovery grooves are provided on the periphery of the bottom of the base, the recovery grooves are inclined at a certain angle to the plane of the base and the upper part of the recovery grooves is inclined outward, and the recovery grooves are made of elastic material so that when the base moves in a certain direction, the gap at the front side of the recovery groove is reduced or completely closed by friction and pressure, and the gap at the rear side of the recovery groove is increased by friction. The recovery groove is connected to the recovery pipe, and the recovery pipe is connected to the recovery pump so that the air pressure in the recovery pipe is less than the atmospheric pressure. The advantage of this design is that the excess coupling agent can be absorbed back to avoid unnecessary waste, and in winter, the climate is relatively cold and a large amount of coupling agent is relatively cold, so the coupling agent in unnecessary places can be absorbed back, so that the user has a better use experience. The coupling agent can be continuously recycled for the same user, and it must be completely renewed for different users.

[0012] Furthermore, an elastic pin is provided on the base to position the probe positioning seat, so that the probe is fixed more stably.

[0013] Furthermore, a handle is provided on the base, a catheter is provided inside the handle to deliver the coupling agent, and a control switch is provided near the handle to control the on and off of the catheter, so that B-ultrasound examination can be performed more conveniently. After the final position is determined, the base is fixed. BRIEF DESCRIPTION OF THE DRAWINGS
