Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical examination auxiliary device for infants lying on their sides. Background Art

[0002] Developmental hip dysplasia is one of the most common skeletal diseases in infants and young children. Ultrasound examination of infant hip joint mainly uses the principle of ultrasound to image the hip joint, and diagnoses whether there are abnormalities in the hip joint and clarifies the developmental status based on observation and analysis of the ultrasonic imaging structure.

[0003] According to the precautions for operation, when doing hip ultrasound, the baby needs to be quiet and keep in the side-lying position, and the lower limb on the examined side needs to be naturally flexed and slightly internally rotated. Then the examiner places the probe on the greater trochanter on the outside of the examined lower limb, and the probe is parallel to the long axis of the body for examination. In the past, when performing hip ultrasound examination on infants, a special medical staff was required to maintain their side-lying posture so that the angle between their trunk and thigh was controlled within a reasonable range. However, in the actual B-ultrasound examination process, infants are prone to hyperactivity due to their lack of autonomous consciousness, which greatly increases the difficulty of control for medical staff. More importantly, even if the medical staff re-intervene, the baby's examination position cannot be accurately reset, which will inevitably cause imaging deviation, thereby affecting the accuracy of the test results, which is not conducive to the doctor's judgment of their condition.

[0004] In recent years, many hospitals have jointly developed a series of medical examination auxiliary devices for infants lying on their sides with medical equipment manufacturers. For example, Chinese utility model patent CN205758596U discloses an infant hip joint ultrasound examination operating table, including a trunk fixing bar, an angle holding device, a chest pillow and a mattress. The mattress is located at the bottom of the operating table, for the examined infant to lie on his side for examination. The two trunk fixing bars are also located on the left and right sides of the mattress. The angle holding device and the chest pillow are also arranged above the mattress. The trunk fixing bar is used to fix the range of motion of the examined infant's body. The angle holding device is used to maintain the bending angle between the infant's trunk and thigh. The hip joint pillow is provided with a holding slope for fitting the infant's legs and buttocks to keep the hip joint and the trunk at an obtuse angle (the angle is 150°, and the doctor can adjust the angle slightly according to the infant's developmental status). The angle holding device includes an adjustable cushion and a hip joint pillow. Although the baby's position can be reliably determined and medical staff can be relieved during the ultrasound examination, due to the different body shapes of babies (mainly determined by gender, months of development, and fatness), medical staff need to frequently add or remove cushions to adjust the relative position of the adjustable pillow size. The entire operation process is relatively cumbersome, and the adhesion reliability between multiple cushions is difficult to ensure, which can easily lead to the position of the baby moving around during the actual B-ultrasound examination. Therefore, medical staff are in urgent need of solving the above problems. Summary of the invention

[0005] Therefore, in view of the above existing problems and defects, medical personnel collected relevant information, combined with years of clinical experience, and after multiple evaluations and considerations, ultimately led to the emergence of the infant side-lying medical examination auxiliary device.

[0006] In order to solve the above technical problems, the utility model relates to an auxiliary device for medical examination of infant side-lying, which is used to fix the side-lying posture of infants under six months old, and assist B-ultrasound examination device to screen or diagnose whether there are abnormalities and developmental conditions of their hip joints. The auxiliary device for medical examination of infant side-lying includes a base, an internal posture stabilizing component, an external posture stabilizing component and a manual push-pull part. The internal posture stabilizing component and the external posture stabilizing component are both supported by the base, and a side-lying channel is formed between the two.

A mounting through hole is provided on the vertical connecting arm for the third fastening assembly to pass freely. In the application state, the vertical connecting arm is in contact with the first external folding plate and is connected as a whole with the help of the third fastening assembly, while the horizontal connecting arm is in contact with the side lying plate and is connected as a whole with the help of the second fastening assembly. In the process of the first external folding plate performing angle adjustment relative to the first external protective composite plate, the relative position between the second fastening assembly and the arc-shaped adjustment hole changes adaptively.

[0010] As a further improvement of the technical solution disclosed in the utility model, the first external protective composite plate is a pull-out design structure, which includes a flip base plate, an external pull-out plate and a fourth fastening assembly. The flip base plate is used as a hinged base for the first external folding plate. The external pull-out plate is inserted into the flip base plate, and the fourth fastening assembly is used to lock the pull-out depth value d1.

[0011] As a further improvement of the technical solution disclosed in the utility model, an external draw-out cavity is provided at the non-hinged end of the flip base plate, and correspondingly, an external draw-out extension section adapted to the external draw-out cavity is extended from the end surface of the external draw-out plate.

[0012] As a further improvement of the technical solution disclosed in the utility model, the built-in stabilizing assembly is a combined design structure, which includes a built-in stabilizing base plate, a built-in pull-out plate and a fifth fastening assembly. The built-in stabilizing base plate is an integrated bending part, and its bending angle is set to β. The built-in pull-out plate is inserted into the built-in stabilizing base plate, and the fifth fastening assembly is used to achieve the locking of the pull-out depth value d2.

[0013] As a further improvement of the technical solution disclosed in the utility model, the end surface of the built-in stable posture base plate extends inward to form a built-in drawer cavity, and correspondingly, a built-in drawer extension section adapted to the built-in drawer cavity extends from the end surface of the built-in drawer plate. A second long waist-shaped hole that is connected to the built-in drawer cavity and allows the fifth fastening component to freely pass through is provided on the top wall of the built-in stable posture base plate, and correspondingly, a second threaded hole for the fifth fastening component to be screwed into is provided on the top wall of the built-in drawer extension section.

[0014] As a further improvement of the technical solution disclosed in the utility model, the built-in stabilizing assembly also includes a guide part to correct its displacement direction. The guide part is composed of at least two guide rods that are inserted on the bottom wall of the built-in stabilizing base plate and linearly evenly distributed along the length direction of the built-in stabilizing base plate. At least two long waist-shaped guide holes parallel to each other are provided on the side lying plate for the guide rods to freely pass through.

[0015] As a further improvement of the technical solution disclosed in the utility model, the manual push-pull part includes a load-bearing plate, a hand-cranked screw assembly and a sixth fastening assembly. The load-bearing plate is in an upright shape, with its bottom surface in contact with the bottom plate, and its inner side surface leaning against the outer wall of the side lying plate. The load-bearing plate is fixedly connected to the side lying plate by means of the sixth fastening assembly. The hand-cranked screw assembly is used to drive the internal stabilizing assembly to perform displacement movement toward / backwards from the external stabilizing assembly, and it uses the load-bearing plate as an assembly basis.

[0016] During the clinical B-ultrasound operation, the infant is first placed in the side-lying channel and kept in the side-lying position. Then, the medical staff uses the manual push-pull part to drive the internal posture stabilizing component to perform displacement movement toward the external posture stabilizing component until the infant is securely clamped, thus paving a good foundation for the next B-ultrasound examination. When the B-ultrasound examination is completed, the medical staff drives the manual push-pull part in the reverse direction to make the internal posture stabilizing component perform displacement movement away from the external posture stabilizing component, so that the infant can be successfully picked up.

[0017] In practical applications, the infant side-lying medical examination auxiliary device disclosed in the utility model has achieved at least the following beneficial technical effects, specifically:

[0018] 1) Medical staff can easily and quickly change the width of the side-lying channel by manually pushing and pulling the built-in posture stabilizing component to perform displacement movement.

DETAILED DESCRIPTION

[0044] In the description of the present invention, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] The infant side-lying medical examination auxiliary device is used to fix the side-lying position of infants under six months old, and assists the B-ultrasound examination device to screen or diagnose whether there are abnormalities and developmental conditions in their hip joints, which is helpful for the attending physician to judge their condition.

[0046] The following is a further detailed description of the contents disclosed in the present utility model in conjunction with specific embodiments. Figure 1 , Figure 2 , Figure 3 The three-dimensional schematic diagrams of the infant side-lying medical examination auxiliary device disclosed in the utility model are respectively shown in three different perspectives. It can be seen that it is mainly composed of a base 1, an internal stabilizing component 2, an external stabilizing component 3 and a manual push-pull part 4. Among them, the internal stabilizing component 2 and the external stabilizing component 3 are both supported by the base, and a side-lying channel is formed between the two. The manual push-pull part 4 is used to drive the internal stabilizing component 2 to perform displacement movement toward / backward to the external stabilizing component 3, so that the opening width of the side-lying channel can be changed.

[0047] like Figure 4 ,5 As shown in the figure, the base 1 is a combined design structure, which includes a bottom plate 11, a side lying plate 12 and a support assembly 13. When performing B-ultrasound examination, the base 1 is placed on the examination table as a whole, and the bottom plate 11 is in contact with the examination table surface. The side lying plate 12 is used to place the baby in the side-lying state, which is parallel to the bottom plate 11 and is located directly above the bottom plate 11. The support assembly 13 is composed of a plurality of support columns 131 connected between the bottom plate 11 and the side lying plate 12 and arranged in a plane uniform state.

[0048] like Figure 6 As shown in , the built-in stabilizing assembly 2 is a modular design structure, and its main body is a built-in stabilizing base plate 21. The built-in stabilizing base plate 21 is an integrated bending part and has a bending angle β. Fig. 9 , 10 As shown in the figure, the external posture stabilizing component 3 is also a modular design structure, which includes a first external protective assembly plate 31, a first external folding plate 32, a pin 33, a first fastening assembly 34 and a posture locking mechanism 35. The first external protective assembly plate 31 is in an upright shape, with its bottom surface in contact with the bottom plate 11, and its inner side surface against the outer wall of the side lying plate 12. The first external protective assembly plate 31 is fixedly connected to the side lying plate 12 by means of the first fastening assembly 34 (as shown in FIG. Fig.19 ). The first external folding plate 32 is also in an upright position, supported by the side lying plate 12, and is hinged to the first external protective assembly plate 31 by a pin 33. According to the different body shapes of the pre-examined infants, the angle α formed between the first external folding plate 32 and the first external protective assembly plate 31 is adaptively adjusted, and after the adjustment is completed, the first external folding plate 32 is locked in position by means of a posture locking mechanism 35, so that the angle α is locked.

[0049] like Fig.17 As shown in the figure, the manual push-pull part 4 is mainly composed of a bearing plate 41, a hand screw assembly 42 and a sixth fastening assembly 43. The bearing plate 41 is in an upright shape, with its bottom surface in contact with the bottom plate 11, and its inner side surface against the outer wall of the side lying plate 12. The bearing plate 41 is fixedly connected to the side lying plate 12 by means of the sixth fastening assembly 43. The hand screw assembly 42 is used to drive the internal stabilizing assembly 2 to perform displacement movement toward / backwards from the external stabilizing assembly 3, and it uses the bearing plate 41 as an assembly basis.

[0050] During the clinical B-ultrasound operation, the infant is first placed in the side-lying channel formed by the internal posture stabilizing component 2 and the external posture stabilizing component 3, and is kept in the side-lying position. Then, the medical staff drives the hand-cranked screw assembly 42, and the internal posture stabilizing component 2 performs a displacement movement toward the external posture stabilizing component 3 due to the thrust, and the width of the side-lying channel is reduced. During the process, the infant is gradually clamped, which lays a good foundation for the next B-ultrasound examination. When the B-ultrasound examination is completed, the medical staff drives the hand-cranked screw assembly 42 in the reverse direction, and the internal posture stabilizing component 2 performs a displacement movement away from the external posture stabilizing component 3 due to the pulling force, and the width of the side-lying channel is expanded, so that the infant can be smoothly picked up.

[0051] In practical applications, the infant side-lying medical examination auxiliary device disclosed in the utility model has achieved at least the following beneficial technical effects, specifically:

[0052] 1) Medical personnel can drive the hand-cranked screw assembly 42 in the forward and reverse directions to make the built-in posture stabilizing assembly 2 perform displacement movement, so as to conveniently and quickly change the opening width of the side-lying channel. In this way, it is ensured that the baby is reliably and stably restrained, which is conducive to maintaining the baby's correct position relative to the B-ultrasound instrument during the examination process, thereby effectively avoiding the occurrence of inaccurate examination results due to the baby's movement during the examination process, which is conducive to the treatment of the baby;

[0053] 2) The opening width of the side-lying channel can also be adaptively changed according to the body shape of the child to be examined, which means that the scope of application of the infant side-lying medical examination auxiliary device is expanded;

[0054] It should also be noted here that, with the aid of the baby side-lying medical examination auxiliary device, only one medical staff member is needed to determine and maintain the baby's posture, which saves time and effort and lays a good foundation for a significant improvement in the efficiency of B-ultrasound examinations.

[0055] As is known, according to design common sense, under the premise of ensuring that the first external folding plate 32 can freely perform rotation angle adjustment relative to the first external protective assembly plate 31, the posture locking mechanism 35 can adopt a variety of design structures to achieve the expected function. However, hereby recommends an implementation scheme with a simple design structure, easy to manufacture and implement, and reliable and stable locking function, specifically: Figure 2 , 10As shown in Figures 15 and 16, the posture locking mechanism 35 is mainly composed of several parts such as a locking member 351, a second fastening assembly 352 and a third fastening assembly 353. Among them, the locking member 351 is a 90° bent sheet metal part, which is connected in sequence by a horizontal connecting arm 3511, an arc transition section 3512 and a vertical connecting arm 3513. An arc-shaped adjustment hole 35111 is provided on the horizontal connecting arm 3511 for the second fastening assembly 352 to pass freely. A mounting through hole 35131 is provided on the vertical connecting arm 3513 for the third fastening assembly 353 to pass freely. In the application state, the vertical connecting arm 3513 is in contact with the first external folding plate 32, and is connected as a whole with the help of the third fastening assembly 353, while the horizontal connecting arm 3511 is in contact with the side lying plate 12, and is connected as a whole with the help of the second fastening assembly 352 (such as Fig.18 As shown in ). If the body shape of the baby to be examined is different from the norm, it is necessary to adjust the angle α formed between the first external folding plate 32 and the first external protective assembly plate 31, so as to ensure that the angle between the trunk and the thigh is controlled within a reasonable value range. In the process of the first external folding plate 32 performing angle adjustment relative to the first external protective assembly plate 31, the locking member 351 undergoes a follow-up deflection movement, and in this process, its deflection path is restricted by the second fastening assembly 352 until the second fastening assembly 352 occupies the correct position relative to the arc-shaped adjustment hole 35111. The following problems were also found during the small-scale trial production stage of medical devices, specifically: when the baby is placed in the side-lying channel, the medical hospital drives the hand-cranked screw assembly 42, and the internal stabilizing assembly 2 is subjected to the push and pull forces and undergoes displacement movement. It is very easy to deflect due to uneven force, and thus it is difficult to cooperate with the external stabilizing assembly 3. In view of this, as a further optimization of the above technical solution, the built-in stabilizing assembly 2 is further provided with a guide portion 24 to correct its displacement direction. The guide portion 24 is composed of at least two guide rods 241 inserted on the bottom wall of the built-in stabilizing base plate 21 and linearly evenly distributed along the length direction of the built-in stabilizing base plate 21 (such as Figure 6 At least two long waist-shaped guiding holes 122 (as shown in FIG. 1 ) are provided on the side lying plate 12 for the guiding rod 231 to freely pass through and are parallel to each other. Figure 4 , 5 As shown in ). When the medical staff drives the internal posture stabilizing assembly 2 with the help of the hand screw assembly 42, the multiple guide rods 231 always slide along the corresponding long waist-shaped guide holes 122, which means that the displacement direction of the internal posture stabilizing assembly 2 is corrected in real time (as shown in ). Fig. 20 , 21 ).

[0056] Furthermore, according to clinical experience, infants' leg lengths vary greatly according to gender, months of development, and personal qualities. In order to improve the versatility of the infant side-lying medical examination auxiliary device and ensure the accuracy of the examination results, as a further refinement of the above design structure, Figure 11-14 As shown in the figure, the first external protective composite plate 31 is a pull-out design structure, which includes a flip base plate 311, an external pull-out plate 312 and a fourth fastening assembly 313. The flip base plate 311 is used as the hinged base of the first external folding plate 32. The external pull-out plate 312 is inserted into the flip base plate 311, and the fourth fastening assembly 313 is used to lock the pull-out depth value d1. As a detailed solution, an external pull-out cavity 3111 is provided at the non-hinged end of the flip base plate 311, and correspondingly, an external pull-out extension section 3121 adapted to the external pull-out cavity 3111 is extended from the end face of the external pull-out plate 312. A first long waist-shaped hole 3122 is provided on the external pull-out plate 312 for the fourth fastening assembly 313 to pass freely, and a first threaded hole (not shown in the figure) is provided on the outer side wall of the side lying plate 12 for the fourth fastening assembly 313 to be screwed in. By adopting the above-mentioned technical solution, when the total length of the first external protective assembly plate 31 needs to be adjusted, the medical staff can first loosen the fourth fastening component 313 until the external pull-out plate 312 and the side wall of the side lying plate 12 are maintained in a disengaged state or a critical contact state, and then drag the pull-out plate 312 outward or inward until the total length of the first external protective assembly plate 31 meets the expected requirements, and the medical staff can re-tighten the fourth fastening component 313.

[0057] In order to achieve the same design purpose, the built-in stabilizing component 2 can also be analogous to the above-mentioned design structure, specifically: Figure 6 As shown, in addition to the built-in stabilizing base plate 21, the built-in stabilizing assembly 2 also includes a built-in pull-out plate 22 and a fifth fastening assembly 23. The built-in pull-out plate 22 is inserted into the built-in stabilizing base plate 21, and the fifth fastening assembly 23 is used to lock the pull-out depth value d2. Figure 7 , 8 As shown in the figure, the end surface of the built-in stabilizing base plate 21 extends inward to form a built-in pull-out cavity 211. Correspondingly, a built-in pull-out extension section 221 adapted to the built-in pull-out cavity 211 extends from the end surface of the built-in pull-out plate 22. A second long waist-shaped hole 212 is provided on the top wall of the built-in stabilizing base plate 21, which is connected to the built-in pull-out cavity 211 and allows the fifth fastening component 23 to pass freely. Correspondingly, a second threaded hole (not shown in the figure) is provided on the top wall of the built-in pull-out extension section 221 for the fifth fastening component to be screwed in. The overall length adjustment method of the built-in stabilizing component 2 is basically the same as that of the external stabilizing component 3 described above. In order to save space, it will not be repeated here.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
