Description

Clinical supplementary natural birth bed of obstetrical department

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an obstetric clinical auxiliary obstetric table.

Background

The benefits of spontaneous delivery are many, and first, in the case of neonates, uterine contraction stimulation during vaginal delivery can promote fetal brain cell development and contribute to the development of neural balance movement of the neonate. And secondly, the birth canal extrudes the fetal lung, so that amniotic fluid in the fetal lung can be discharged, the alveolus is stimulated to generate active substances, the normal lung respiration establishment of a newborn is facilitated, and the occurrence of wet lung and respiratory distress syndrome of the newborn is reduced. Therefore, more and more parturients now choose a proper delivery fetus.

At present, the normal labor of the lying-in women is mostly performed on an obstetric table. The existing obstetric table generally comprises a bed plate and a backrest, wherein the bed plate and the backrest are generally in a flat plate shape, the shapes of different puerperae bodies are substantially different, and the contact areas and the force applying points of the puerperae bodies when the puerperae bodies lie on the bed plate or the backrest are different. But the bed board of the obstetric table can not be adjusted by the plate surface of the backrest, so that the lying-in woman can hardly feel comfortable all the time.

When in normal delivery, the fetus extrudes the intestinal tract, so that the fetus has the defecation feeling. Also during this process, there is a possibility that excrement is discharged, which is normal. Therefore, the obstetric table is generally paved with the disposable medical pad, and the obstetric table is cleaned manually after production. The existing obstetric table does not have a sealing function, and excrement is not fixed in many times and possibly exists in many places in the obstetric table, so that the cleaning is very time-consuming and labor-consuming. Generally, many hospitals only have one delivery room, if the number of the puerperae is too large, the use efficiency is affected, the puerperae in the natural delivery does not want to be delivered through caesarean, most of the puerperae can not be born on time, and the puerperae can not wait for too long time in the process of birth, so that the delivery room and the delivery bed are required to be in a usable state most of the time.

Also, during normal delivery, the fetus comes out first of all with the head. For a fetus with an abnormal birth, a doctor is also required to assist in pulling the fetus out of the woman's vagina. When in operation, a doctor sucks the head of the fetus by using a manual sucking disc, and then manually pulls out the fetus by using the assistance force in an arc-shaped track from bottom to top. But the existence of excrement causes inconvenience to doctors in operation.

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the invention discloses an obstetrical clinical antenatal auxiliary device, which comprises a bed body and a control system. The bed body includes bed board 2, and the bottom of bed board 2 is equipped with a plurality of elevating system, utilizes elevating system in order to adjust the vertical distance between bed board 2 and the ground to the user lies on bed board 2.

In the scheme, three lifting mechanisms are arranged and are uniformly distributed along the length direction of the bed plate 2. The lifting mechanism comprises a base 13, a bidirectional cylinder 12 and a supporting seat 11. Supporting seat 11 and bed board 2 fixed connection, the piston rod of two-way cylinder 12 is articulated with supporting seat 11, and two-way cylinder 12 fixed connection is on base 13.

The bed board 2 is connected with a back plate 8 through a rotating mechanism. The rotating mechanism comprises a rotating shaft and a small motor 9. The bed board 2 is hinged with the back board 8 through a rotating shaft. The pivot with back plate 8 fixed connection, the pivot with bed board 2 rotates to be connected, small motor 9 and bed board 2 fixed connection, and the output shaft and the coaxial fixed of pivot of small motor 9 drive pivot are rotatory and then adjust the face of back plate 8 and the ascending contained angle size of horizontal direction through small motor 9. That is, the angle of the backrest plate 8 is driven by the small motor 9, and the backrest plate is not manually operated.

In the scheme, a plurality of air bags 5 are arranged on the bed plate 2 and the backrest plate 8. All the air bags 5 are uniformly distributed along the long direction of the plate surface of the backrest plate 8 of the bed plate 2. The length of the air bag 5 on the bed board 2 is equal to the width of the bed board 2, and the length of the air bag 5 on the back board 8 is equal to the width of the back board 8. In the optimized embodiment, the cross section of the air bag 5 is semicircular, and the bottom plane of the air bag 5 is fixedly connected with the bed plate 2 or the backrest plate 8.

Whether the air bag 5 is inflated or how much compressed air is inflated and how much deformation is generated is performed by the control system in the scheme. The control system comprises a main control module, unit control systems and an air compressor, wherein one unit control system corresponds to one air bag 5, and the main control module controls all the unit control systems. The unit control system comprises a unit control module, a first air pressure sensor, an air inlet pipe and an exhaust pipe, wherein an air inlet electric control valve is arranged on the air inlet pipe, the on-off of the air inlet pipe is controlled by the air inlet electric control valve, one end of the air inlet pipe is communicated with an air compressor, the other end of the air inlet pipe is communicated with a corresponding air bag 5, and compressed air is introduced into the air bag 5 by the air compressor; and an exhaust electric control valve is arranged on the exhaust pipe, the exhaust electric control valve is utilized to control the on-off of the exhaust pipe, one end of the exhaust pipe is communicated with the corresponding air bag 5, and the other end of the exhaust pipe is communicated with the atmosphere.

In particular, each unit control module is used to control one airbag 5. The principle of control is shown in fig. 4 and is divided into three processes. The process a: all the air bags 5 are filled with certain compressed air firstly, and the value of the compressed air in the air bags 5 is controlled to be p1 (generally 1/3 of the maximum pressure-bearing limit of the air bags 5); and a process b: when lying on the bed board 2 and the head or back of the parturient leans against the backrest board 8, each unit control module detects the compressed air value in each air cell 5 through the respective first air pressure sensor and records the compressed air value in the main control module. Through comparing the compressed air value in each air bag 5 in the process a and the process b, a lying curve which is most suitable for the bed plate 2 and the back plate 8 when the back of the user lies on the bed plate 2 and the back plate 8 can be obtained, and the main control module flushes corresponding air pressure into each air bag 5 in a proportional mode according to the curve, so that the air bags 5 along the long direction of the bed plate 2 and the back plate 8 are concave and convex, a state similar to the shape of the back of the user when the user lies is formed, each part of the body of the user can be in contact with the air bags 5, and the hardness degrees of the contacted air bags 5 are approximately equal. At the moment, the user feels most comfortable, and the force sent by each part of the body is most suitable when the parturient gives out the fetus with strength.

In the process, the back curves of different users are different, but the process a and the process b are repeated, so that the concave-convex curve formed by the air bags 5 along the length direction of the bed plate 2 and the backrest plate 8 is inosculated with the back curve of the user, and then the back of the user can be powerfully supported by the air bags 5 when the user lies or sits and lies, and the comfort level is better. The backrest angle of the backrest plate 8 can be adjusted through the small motor 9, the overall height of the bed plate 2 and the inclination angle of the bed plate 2 can be adjusted through the three lifting mechanisms, so that a puerpera can feel more comfortable when the puerpera is in the midwifery delivery, and a doctor can deliver the puerpera in the most favorable posture by adjusting the angles so as to facilitate the operation.

The present invention also contemplates such a configuration for cleaning purposes. Be equipped with scalable waterproof cushion 3 on the face that bed board 2 was kept away from to gasbag 5 also for gasbag 5, scalable waterproof cushion 3 covers entirely bed board 2 and back board 8 to scalable waterproof cushion 3 is connected with detachable connected mode and gasbag 5, if adopt the detachable adhesive structure that the magic was pasted.

As shown in fig. 1, the two sides of the telescopic waterproof cushion 3 along the width direction of the bed plate 2 are provided with water-blocking folding awnings 4, and the water-blocking folding awnings 4 are foldable along the length direction of the bed plate 2. No matter what angle the back plate 8 is at, what kind of curve is changed to scalable waterproof cushion 3 under the effect of gasbag 5, and manger plate folding covering 4 homoenergetic prevents effectively that clean water from splashing out the bed body. Meanwhile, the device can effectively isolate the splashing of the excrement of the puerpera so as to avoid the contamination of the delivery room. The protection of the delivery room environment is realized as much as possible, so that the turnover use efficiency of the delivery room is accelerated by replacing the telescopic waterproof cushion 3.

And in a further optimization, electric heating wires are embedded inside the telescopic waterproof cushion 3. The electric heating wire can realize the heating of the telescopic waterproof cushion 3 so as to avoid the puerpera from being cooled. As an optimization, the retractable waterproof cushion 3 can be a latex cushion or a silica gel cushion.

It is known that the fetus sometimes needs the assistance of a doctor when being separated from the body of the parturient. The existing assistance mode is manually performed by a doctor. The head of the fetus is sucked by a manual midwifery device similar to a sucking disc, and then the fetus is assisted to be ejected from the body of the parturient from bottom to top in an arc-shaped track. However, this procedure is a burden on the doctor, which sometimes makes it difficult for the doctor to take into account other symptoms of the parturient, and sometimes makes it difficult for the doctor to operate in the presence of excrements. Therefore, the invention also designs a midwifery mechanism 1.

As shown in fig. 3, the midwifery mechanism 1 comprises a support body 15, a hanging seat 14 is fixedly installed on the support body 15, an arc-shaped slideway 14a and an arc-shaped friction step 14b are arranged on the hanging seat 14, the arc-shaped slideway 14a and the arc-shaped friction step 14b are concentric, and a moving assembly is arranged in the arc-shaped slideway 14 a; the moving assembly comprises a main hanging rod 16 and an auxiliary hanging rod 17 which are parallel to each other and are vertically arranged, the upper end of the auxiliary hanging rod 17 is rotatably connected with a pulley, the auxiliary hanging rod 17 is rotatably connected with the arc-shaped track through the pulley, and the lower end of the auxiliary hanging rod 17 is fixed with the main hanging rod 16; a connecting shaft is arranged at the upper end of the main hanging rod 16 and penetrates through the arc-shaped slide way 14a along the axial direction, one end of the connecting shaft is rotatably connected with the upper end of the main hanging rod 16, a friction wheel 19 is fixedly arranged at the other end of the connecting shaft, and the wheel surface of the friction wheel 19 is abutted to the arc-shaped step surface of the arc-shaped friction step 14 b; the upper end of the main hanging rod 16 is also fixedly provided with a driving motor 18, an output shaft of the driving motor 18 is coaxially fixed with the connecting shaft, and the driving motor 18 can drive the friction wheel 19 to rotate so as to realize that the friction wheel 19 moves along the arc-shaped steps.

The lower end of the main hanging rod 16 is provided with a pull-assisting assembly, the pull-assisting assembly comprises a pull-assisting cylinder 20, a vacuum air pump and a fixed sucker 22 adapted to the shape of the head of the fetus, and the vacuum air pump is communicated with the fixed sucker 22; the pull-assisting cylinder 20 is rotatably connected with the main hanging rod 16, a piston rod of the pull-assisting cylinder 20 is coaxially fixed with the fixed sucker 22, the piston rod of the pull-assisting cylinder 20 is sleeved with a tension spring 21, one end of the tension spring 21 is fixed with the pull-assisting cylinder 20, and the other end of the tension spring 21 is fixed with the fixed sucker 22.

The pull-assisting cylinder 20 of the delivery assisting mechanism 1 moves along the track of the arc-shaped slide way 14a from bottom to top under the synergistic action of the main hanging rod 16, the auxiliary hanging rod 17, the arc-shaped slide way 14a and the driving motor 18, so that the movement track of a doctor during manual fetal pull assisting is simulated. The pulling-assisted cylinder 20 is fixed with the head of the fetus through the fixed suction cup 22, so as to provide an acting point for pulling the fetus. The principle of the connection of the fixed suction cup 22 to the fetal head is as follows: the fixed suction cup 22 approaches the direction of the bed body until the fixed suction cup 22 contacts with the head of the fetus, and at this time, manual guidance is needed by a doctor. The vacuum is then drawn by the vacuum pump and the fixed suction cup 22 holds and holds the fetal head. The driving motor 18 drives the friction wheel 19 to rotate through the connecting shaft, the rotating friction wheel 19 pulls the main hanging rod 16 and the auxiliary hanging rod 17 to move along the arc-shaped slide way 14a to the direction far away from the bed body, and in the process, the auxiliary pulling cylinder 20 and the main hanging rod 16 can rotate, so that the adaptation of angle change can be automatically completed, and the simulation of manually pulling the fetus is finally realized.

The above process enables automated pulling of the fetus. In a further optimization, the fixed suction cup 22 has a conical inner cavity, the fixed suction cup 22 axially comprises a closed end and an open end, and the inner cavity of the fixed suction cup 22 is gradually enlarged from the closed end to the open end; an annular inflatable rubber ring 25 is arranged at the open end of the fixed sucker 22, and the outer ring surface of the annular inflatable rubber ring 25 is fixedly connected with the open end of the fixed sucker 22 in a sealing manner along the circumferential direction of the fixed sucker 22; the annular inflatable rubber ring 25 is provided with an inflatable tube communicated with compressed air. The open end of the fixed suction cup 22 is provided with a plurality of annular inflatable rubber rings 25, and the diameter of the inner annular surface of each annular inflatable rubber ring 25 is gradually increased from the closed end to the open end of the fixed suction cup 22.

The working principle of the optimized fixed suction cup 22 is as follows: the annular inflatable rubber ring 25 is in contact with the head of the fetus after the open end of the fixed suction cup 22 first contacts the head of the fetus. Compressed air is injected into the annular inflatable rubber ring 25 through the inflation tube, and the annular inflatable rubber ring 25 expands and is tightly attached to the skin of the head of the fetus. The vacuum pump draws the interior of the fixed suction cup 22 to vacuum and maintains it. If the annular inflatable rubber ring 25 is loosened from the scalp of the fetus during the pulling process of the fetus, the inflation tube continues to inject the compressed air into the annular inflatable rubber ring 25, and the vacuum suction pump continues to suck the air inside the fixed suction cup 22 at the same time until the fixed suction cup 22 sucks the head of the fetus again.

During the above process, it is possible that the detachment of the annular inflatable rubber ring 25 from the fetal head is instantaneous and the system is not ready to react. Several annular inflatable rubber rings 25 are therefore designed. When the fixed suction cup 22 contacts with the head of the fetus, the contact position of each inflatable rubber ring with the head of the fetus is different, and the annular inflatable rubber rings 25 with different inner annular surface diameters are just matched with the shape of the head of the fetus. The vacuum area formed between the fixed suction cup 22 and the fetal head is gradually enlarged from the closed end to the open end, and multi-stage connection and fixation are formed. This effectively solves the problem that the holding cup 22 is unstable in holding the fetus.

However, we also consider other factors in the design. Such as: when the body of the fetus is too large, the fetus is not easy to separate from the mother. If the fetus is forcibly pulled, it may cause injury to the parturient. Therefore, the degree of vacuum inside the fixed suction cup 22 needs to be controlled. How to control this vacuum, we consider doing this as follows:

a millimeter scale 23 is arranged on the pull-assisting cylinder 20 along the axial direction of the piston rod, and one end of the millimeter scale 23 is fixedly connected with the fixed sucker 22; a sliding block made of transparent plastic is fixed on the pull-assisting cylinder 20, and the millimeter-scale ruler 23 penetrates through the sliding block and is in sliding fit with the sliding block; a triangular pointer 24 is fixed on the slide block, and the triangular pointer 24 points to the millimeter scale 23.

When the child is pulled, the pull-assisting cylinder 20 relies not on the pneumatic energy of the pull-assisting cylinder 20 but on the restoring force of the tension spring 21. Mainly because the action of cylinder is too fast, and the extension spring 21 moves more slowly when resumeing the deformation, more with the action that the manual pulling foetus of manual work matches. By reading the size of the millimeter scale 23 indicated by the triangular pointer 24, we can easily obtain the restoring force value of the tension spring 21 because it can be calculated by multiplying the deformation length of the tension spring 21 by the deformation coefficient of the tension spring 21. Therefore, the structure is designed, the force for pulling the fetus is controlled by rapidly reading the deformation length of the tension spring 21 and further obtaining the restoring force of the tension spring 21, so that the injury to the fetus or a pregnant woman caused by excessive force is avoided, and the fetus is pulled within a controllable range. When this range is exceeded, the tension spring 21 will act in the opposite direction or will not contract but will stretch, and the fixed suction cup 22 will no longer pull the fetus outwards.

Furthermore, we can also control the vacuum between the fixed suction cup 22 and the fetal head by providing a second air pressure sensor in the fixed suction cup 22. The pressing force of the annular inflatable rubber ring 25 on the fetal scalp is adjusted by adjusting the vacuum degree, so that the head of the fetus is prevented from being injured by the annular inflatable rubber ring 25.

As shown in fig. 1, a grab bar 7 for a parturient to hold is further disposed on the backrest plate 8, and a grip 6 is rotatably connected to an end of the grab bar 7 far from the backrest plate 8. When the lying-in woman gives strength to give birth to the fetus, the handle 6 can be held by the lying-in woman. In the process of the parturient taking a fetus, the delivery assisting mechanism 1 moves in the direction far away from the bed body. We want to: if the parturient can control the birth of the fetus by himself with the aid of the midwifery mechanism 1, it is a great advantage for the parturient, because the parturient's own feelings are more important than the doctor's judgment once he feels the unfavorable condition.

Thus, we have a pressure sensor inside the grip 6 and electrically connect the pressure sensor to the drive motor 18 through the control system. When the parturient clenches the grip 6 with hand strength, the pressure sensor on the grip 6 transmits the signal to the driving motor 18, at this time, the driving motor 18 can drive the friction wheel 19 to rotate, and the midwifery mechanism 1 can work normally; when the parturient releases the grip 6, the pressure sensor completely blocks the drive motor 18, and the drive motor 18 can no longer continue to operate. It is equivalent to a pressure sensor which is used as a protective measure for lying-in women. When a lying-in woman feels that the body of the lying-in woman cannot bear the pain of breaking away from the fetus, the aid of the delivery assisting mechanism 1 can be immediately stopped by loosening the handle 6, and compared with the situation that a doctor judges firstly and then operates the delivery assisting mechanism 1 to stop, the method is more direct and effective, and protects the lying-in woman to the greatest extent.

The above description is only exemplary of the present invention and should not be taken as limiting, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
