Description

Technical Field

[0001] The utility model relates to the technical field of artificial amniotomy, in particular to an artificial amniotomy assisting device. Background Technique

[0002] Artificial amniotomy refers to using external force to rupture the fetal membrane as early as possible so that the fetal head is in direct contact with the cervical os, enabling the prostaglandin in the amniotic fluid to contact the cervix, which can degrade prostaglandin dehydrogenase, promote cervical ripening, discharge amniotic fluid, observe the color of amniotic fluid, reduce the volume of the uterus, make the presenting part descend, stimulate the cervix, promote cervical dilation, and reflexively cause uterine contractions, so as to achieve the purpose of accelerating childbirth. It is a commonly used induction method in the process of natural childbirth.

[0003] At present, when performing artificial intervention, the common artificial amniotomy methods used by obstetricians are to assist artificial amniotomy with a disposable syringe or amniotomy needle or hemostatic forceps or disinfected cotton swab. In this process, the doctor needs to push the disposable syringe or amniotomy needle or hemostatic forceps through the birth canal to the position of the fetal membrane. The doctor operates in the closed space of the vagina and cannot see the cervix and amniotic sac. Therefore, it must be done by touch, which is difficult to operate. It is very easy to injure the parturient's birth canal during the pushing process. If the puncture is too deep during amniotomy, it is easy to injure the fetus, pregnant women and medical staff by needle puncture. According to research, the success rate of artificial amniotomy is related to many factors such as the visual pain score of pregnant women during artificial amniotomy, the occupational exposure rate of medical staff, the cesarean section rate, the fetal injury rate, the subjective feeling rate of medical staff, and the glove breakage rate and occupational exposure rate of artificial amniotomy gloves. In addition, working in the delivery room requires more contact with the body fluids, blood and pathogens of pregnant women, which will significantly increase the probability of occupational exposure risks. Medical staff in the delivery room have become a high-risk group for occupational exposure. Blood-borne occupational exposure mainly occurs in sharp injuries, one of which is needle puncture during artificial amniotomy. The traditional artificial amniotomy assisting device is inconvenient and unsafe to operate. Based on this, we propose a new type of artificial amniotomy assisting device with simple, convenient and safe operation methods, which can avoid the blade from contacting the fetus, thus better protecting pregnant women and medical staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide an artificial amniotomy assisting device to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solution: An artificial membrane rupture assisting device, comprising a membrane rupture finger sleeve main body and a hook-shaped membrane rupture blade. The membrane rupture finger sleeve main body is sequentially provided with a first finger joint corresponding area, a second finger joint corresponding area, and a third finger joint corresponding area which are movably connected from top to bottom. A scale layer is provided on the outer side wall of the second finger joint corresponding area, and anti-slip protrusions are provided on the outer side wall of the third finger joint corresponding area. The hook-shaped membrane rupture blade is embedded at the top end inside the membrane rupture finger sleeve main body. An elastic recessed member connected to the hook-shaped membrane rupture blade is provided on the first finger joint corresponding area. A reserved amniotic fluid suction tube buried inside the side wall of the membrane rupture finger sleeve main body is fixed on the hook-shaped membrane rupture blade.

[0006] Preferably, the connections of the first finger joint corresponding area, the second finger joint corresponding area, and the third finger joint corresponding area are sequentially provided as bendable structures.

[0007] Preferably, a medical rigid PET base layer is provided inside the side walls of the first finger joint corresponding area, the second finger joint corresponding area, and the third finger joint corresponding area.

[0008] Preferably, an outer medical silicone anti-scratch layer is provided on the outer side walls of the first finger joint corresponding area, the second finger joint corresponding area, and the third finger joint corresponding area.

[0009] Preferably, an inner medical flexible PVC anti-slip layer is provided on the inner side walls of the first finger joint corresponding area, the second finger joint corresponding area, and the third finger joint corresponding area.

[0010] Preferably, a closed end is provided at the top end of the membrane rupture finger sleeve main body, and an open end is provided at the bottom end of the membrane rupture finger sleeve main body.

[0011] Preferably, a one-way valve is installed at the bottom of the reserved amniotic fluid suction tube.

[0012] Preferably, an inner threaded layer for assembly is provided inside the bottom end of the reserved amniotic fluid suction tube.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) The artificial amniotomy assisting device is equipped with a rupture finger sleeve body, etc., which optimizes its own performance. On the one hand, there is an elastic recess part, i.e., an elastic recess member, in the inner wall of the cylindrical device of one of the rupture finger sleeve bodies. The inner side of this part is connected and fixed to a hooked rupture blade, so that the hooked rupture blade forms a blunt head in the non-use state. Subsequently, when the fingertip of the user with the device bends, the elastic recess part, i.e., the elastic recess member, which is usually in the contracted position, is punctured. At this time, the hooked rupture blade protrudes out of the device and radially extends to expose the tip. At this time, the user can use it to rupture the amniotic sac. On the other hand, a scale layer is arranged at the position of the finger ventral surface of the rupture finger sleeve body close to the corresponding area of the second finger joint, which is convenient for mastering the length inserted into the vagina and can dynamically understand the fetus reaching each plane of the pelvis. Moreover, the finger ventral surface of the corresponding area of the third finger joint on the rupture finger sleeve body is increased with uneven protrusions, i.e., anti-slip protrusions, which can increase the anti-slip property of the finger sleeve structure, solve the problem that the viscous secretions secreted by the vagina make the device inconvenient for intravaginal operation, and can effectively prevent the finger sleeve structure from slipping off;

[0015] (2) The artificial amniotomy assisting device is equipped with a hooked rupture blade, etc. When the device is actually used, on the one hand, the rupture knife structure of this design is a hooked rupture blade, and its tip is hooked. Compared with the conventional conical or pointed shape, it can not only avoid hurting the fetus or damaging the patient's cervix or vaginal wall, but also prevent the needlestick injury of medical staff and avoid iatrogenic infection, thus facilitating the smooth incision of the fetal membrane. On the other hand, the user can suck out the amniotic fluid smoothly through the amniotic fluid suction reserved tube with the opening facing the hooked rupture blade and cooperate with an external adsorption structure, so that the amniotic fluid in the fetal membrane can be attracted to the outside, which is convenient for analyzing the state of the parturient through the amniotic fluid and also avoids the pollution of the amniotic fluid to medical staff and the surrounding environment. In the past, medical staff held a disposable syringe needle or a forceps, which caused great panic to pregnant women. The appearance of this design can often reduce the fear of patients, with good compliance and strong practicability. And by installing a one-way valve at the bottom of the amniotic fluid suction reserved tube, it can avoid the problem of liquid backflow when sucking out the amniotic fluid in the fetal membrane and improve the safety of the operation. Also, by using the internal thread layer for assembly arranged at the bottom end of the amniotic fluid suction reserved tube, it is convenient to use a threaded connection structure to realize the connection between the device and the corresponding adsorption equipment;

[0016] (3) The artificial amniotomy assisting device is installed with the corresponding area of the second finger joint, etc., which optimizes its own structure. On the one hand, by setting the device as a cylindrical amniotomy finger sleeve body, with its two ends respectively set as an open end and a closed end, and the amniotomy finger sleeve body is successively provided with a first finger joint corresponding area, a second finger joint corresponding area, and a third finger joint corresponding area, and the joints of the first finger joint corresponding area, the second finger joint corresponding area, and the third finger joint corresponding area are successively set as bendable structures, the device has an optimized structure, is suitable for being placed on the finger and operated by the finger, and is thus convenient for rupturing the amniotic sac during obstetric surgery. This makes the device convenient for finger carrying and operation, highly convenient, and easy to promote. On the other hand, by successively arranging a composite structure composed of an inner medical flexible PVC anti-slip layer, a medical rigid PET base layer, and an outer medical silica gel anti-scratch layer on the first finger joint corresponding area, the second finger joint corresponding area, and the third finger joint corresponding area that make up the amniotomy finger sleeve body, the device has a soft and anti-scratch outer wall, anti-slip inner wall, and a rigid material support in the middle, improving the use effect.
