Description

Technical Field

[0001] The present invention relates to the technical field of pulse fixing sleeves, and particularly to a neonatal care pulse fixing sleeve. Background Art

[0002] Due to being newly born, many newborns will have various diseases and risks during the production process or due to congenital factors. At this time, they need to be transferred to the neonatal intensive care unit. In the neonatal intensive care unit, most doctors face many complex problems. Considering that they are dealing with newborns, there are very high requirements in all aspects, whether it is instruments, facilities, drugs, or the overall quality of medical staff.

[0003] For critically ill newborns, it is generally necessary to continuously measure various values such as pulse, heart rate, and blood pressure. During this process, since most monitoring instruments need to use a measuring tape to wrap around the pulse of the newborn, there are certain problems in actual use:

[0004] 1. Since the measuring tapes of such monitoring instruments are mostly large, and the wrists of newborns are very soft and delicate, the measuring tape cannot be fully attached to the wrists of newborns. At the same time, because newborns are prone to moving around randomly, the measuring tape may fall off, affecting the monitoring of pulse and heart rate;

[0005] 2. The edges and interiors of the measuring tapes of most monitoring instruments are relatively rough. Since the skin of newborns is delicate, when newborns move around a lot, the measuring wristbands may scratch the wrists of newborns, which is not conducive to use. Summary of the Invention

[0006] The purpose of the present invention is to provide a neonatal care pulse fixing sleeve to solve the problems that the measuring tape of the monitoring instrument is large, while the wrists of newborns are very soft and delicate, resulting in the inability of the measuring tape to be fully attached to the wrists of newborns. At the same time, because newborns are prone to moving around randomly, the measurement is prone to falling off; the edges and interiors of the measuring tape are relatively rough. Since the skin of newborns is delicate, when newborns move around a lot, the measuring wristband is prone to scratching the wrists of newborns.

[0007] To achieve the above purpose, the present invention provides a neonatal care pulse fixing sleeve, including a base ring that can be opened and closed. A pulse measuring tape that can slide within a certain range is arranged inside the base ring. An opposing fitting mechanism for squeezing the pulse measuring tape to fit the wrist is arranged on the base ring. A shielding ring with an edge exceeding the base ring is arranged inside the base ring. A plurality of anti-collision patches with edges exceeding the outermost edge of the opposing fitting mechanism are arranged on the outer wall of the base ring;

[0008] The pulse measuring tape cooperates with the shielding ring to form an all-round annular fitting sleeve inside the base ring;

[0009] The base ring includes a base loop, an opening and closing side loop, and a locking mechanism. The base loop and the opening and closing side loops are both arc-shaped loops. Two of the opening and closing side loops are installed in a group and rotatably mounted on both side edges of the base loop respectively. The locking mechanism is arranged between the ends of the two opening and closing side loops away from the base loop and can be locked to form a lock between the ends of the two opening and closing side loops.

[0010] Through grooves that are mirror-symmetric are provided on the loop walls of the base loop and the opening and closing side loops. A set of opposite fitting mechanisms is provided at the edges of the through grooves of the base loop and the opening and closing side loops respectively. Among them, the opposite fitting mechanism on the base loop acts on the shielding loop, and the opposite fitting mechanism on the opening and closing side loop acts on the pulse measurement belt.

[0011] As a further improvement of this technical solution, the opposite fitting mechanism includes an outward convex mounting ring, a rotating extrusion piece, a torsion spring, and an outward pulling rope body. Two of the outward convex mounting rings are in a group and are provided at the edges of the outer wall through grooves of the base loop and the opening and closing side loops respectively. Two of the rotating extrusion pieces are in a group and are rotatably mounted in the two outward convex mounting rings of the same group respectively, and the rotating extrusion pieces of the same group are mirror-symmetric. The rotating end of the rotating extrusion piece passes through the through groove. The torsion spring is arranged at the connection between the outward convex mounting ring and the rotating extrusion piece, so that the rotating extrusion piece maintains a rotating trend of passing through the through groove. The outward pulling rope body is arranged on the outer wall of the rotating extrusion piece.

[0012] As a further improvement of this technical solution, the rotating extrusion piece is an arc-shaped piece, and the inner arc side faces the side of the base ring. A connecting piece is provided on the outer wall of the rotating extrusion piece. The two ends of the outward pulling rope body are respectively connected to the connecting pieces on the outer walls of the rotating extrusion pieces of the same group, so that the two rotating extrusion pieces of the same group can be synchronously rotated outward by pulling the outward pulling rope body.

[0013] As a further improvement of this technical solution, the outward pulling rope body is a hard rubber rope body, and the outer edge of the outward pulling rope body extends beyond the edge of the anti-collision patch.

[0014] As a further improvement of this technical solution, the locking mechanism includes a positioning rotating frame and a locking belt. The positioning rotating frame is rotatably mounted at the end of one of the opening and closing side loops. The locking belt is arranged at the end of the other opening and closing side loop. A through slot is provided on the positioning rotating frame. Magic tapes for sticking are provided on the belt body and the end of the locking belt, so that the end of the locking belt can pass through the through slot of the positioning rotating frame and then stick to the belt body of the locking belt to achieve end-to-end sticking.

[0015] As a further improvement of this technical solution, an inner concave is provided on the inner arc wall of the opening and closing side loop. A multi-directional limiting component is provided at the inner concave of the opening and closing side loop. A clamping piece for buckling in the limiting component is provided on the outer arc surface of the pulse measurement belt.

[0016] As a further improvement of the technical solution, the limiting component includes a horizontal limiting block and a vertical limiting block. The horizontal limiting block includes two horizontally arranged limiting blocks with opposite openings, and the vertical limiting block includes two vertically arranged limiting blocks with opposite openings. The horizontal limiting block and the vertical limiting block are both arranged at the central concave part of the opening and closing side ring, and the four limiting blocks are arranged in a surrounding manner. The clamping piece is a cross-shaped sheet body, and the four corners of the clamping piece can be respectively inserted into the four surrounding limiting blocks.

[0017] As a further improvement of the technical solution, the distance between the two limiting blocks of the horizontal limiting block is greater than the length of the horizontal sheet body of the clamping piece, and the distance between the two limiting blocks of the vertical limiting block is greater than the length of the vertical sheet body of the clamping piece, so that when the clamping piece is inserted into the four limiting blocks, there is a certain movement gap in all four directions.

[0018] Compared with the prior art, the present invention provides a neonatal monitoring pulse fixing sleeve, which has the following beneficial effects:

[0019] 1. Through the combined action of the base ring, the pulse measurement belt, the shielding ring, the locking mechanism and the opposing fitting mechanism, the present invention further squeezes the inner pulse measurement belt through the opposing fitting mechanism on the base ring, and at the same time, the locking effect of the base ring itself forms a double lock on the outer side of the fixed ring sleeve jointly formed by the pulse measurement belt and the shielding ring, helping the pulse sleeve to stably fit on the outer side of the neonatal wrist and effectively preventing the pulse measurement belt from falling off;

[0020] 2. Through the movement of the clamping piece on the outer arc surface of the pulse measurement belt on the limiting component at the concave part of the opening and closing side ring, a certain movement space can be formed between the fixed ring sleeve jointly formed by the pulse measurement belt and the shielding ring and the base ring, preventing the base ring from driving the inner pulse measurement belt to shift and rub against the neonatal wrist when the neonatal arm moves randomly, and better protecting the neonate.

[0030] Embodiment 1

[0031] Referring to Figures 1-6 , a neonatal monitoring pulse fixing sleeve. In order to better fix the measurement belt at the wrist of the neonate and make it fit better, a basic ring 1 that can be opened and closed is provided here. Inside the basic ring 1, a pulse measurement belt 2 that can slide within a certain range is provided. On the basic ring 1, an opposing fitting mechanism for squeezing the pulse measurement belt 2 to fit the wrist is provided. Inside the basic ring 1, a shielding ring 3 with edges exceeding the basic ring 1 is provided. On the outer wall of the basic ring 1, a plurality of anti-collision patches 4 with edges exceeding the outermost edge of the opposing fitting mechanism are provided. The use of a plurality of anti-collision patches 4 forms a protective structure for the outer ring at the outer side of the basic ring 1 and the edge of the opposing fitting mechanism, which can prevent the protruding opposing fitting mechanism from scratching the neonate;

[0032] The pulse measurement belt 2 cooperates with the shielding ring 3 to form an all-round annular fitting sleeve inside the basic ring 1. Since both sides of the shielding ring 3 exceed the pulse measurement belt 2 and the shielding ring 3 and the pulse measurement belt 2 are split sleeves, a certain amount of movement space can be formed on both sides of the pulse measurement belt 2 by the shielding ring 3. When the wrist of the neonate bends, a certain amount of bending space can be provided to prevent the neonate from crying due to discomfort caused by excessive restraint of the wrist.

[0033] The base ring 1 includes a base ring 101, an opening and closing side ring 102, and a locking mechanism. Both the base ring 101 and the opening and closing side ring 102 are arc-shaped rings. A through groove for connecting wires to pass through is provided on the base ring 101, which can facilitate the external wires to pass through the base ring 101 and connect to the pulse measurement belt 2. Two opening and closing side rings 102 are a group and are respectively rotatably installed at both side edges of the base ring 101. The locking mechanism is arranged between the ends of the two opening and closing side rings 102 away from the base ring 101, and can form a lock between the ends of the two opening and closing side rings 102. The base ring 101 and the two opening and closing side rings 102 can form a circular ring body with one side being openable;

[0034] Through grooves that are mirror-symmetric are provided on the ring walls of the base ring 101 and the opening and closing side ring 102. A set of opposing fitting mechanisms are provided at the edges of the through grooves of the base ring 101 and the opening and closing side ring 102 respectively. Among them, the opposing fitting mechanism on the base ring 101 acts on the shielding ring 3, and the opposing fitting mechanism on the opening and closing side ring 102 acts on the pulse measurement belt 2, so that when surrounding the wrist of a newborn, both the pulse measurement belt 2 and the shielding ring 3 can be inwardly pressed and fitted to the wrist of the newborn on the inner side of the base ring 1.

[0035] The opposing fitting mechanism includes an outwardly convex mounting ring 5, a rotating pressing piece 6, a torsion spring 7, and an outward pulling rope body 8. Two outwardly convex mounting rings 5 are a group, and a set of them are provided at the edges of the outer wall through grooves of the base ring 101 and the opening and closing side ring 102 respectively. Two rotating pressing pieces 6 are a group and are respectively rotatably installed in the two outwardly convex mounting rings 5 of the same group, and the rotating pressing pieces 6 of the same group are mirror-symmetric. The rotating end of the rotating pressing piece 6 passes through the through groove. The torsion spring 7 is arranged at the connection between the outwardly convex mounting ring 5 and the rotating pressing piece 6, so that the rotating pressing piece 6 maintains a rotating trend of passing through the through groove. The outward pulling rope body 8 is arranged on the outer wall of the rotating pressing piece 6.

[0036] The rotating pressing piece 6 is an arc-shaped piece, and the inner arc side faces the side of the base ring 1. A connecting piece is provided on the outer wall of the rotating pressing piece 6. Both ends of the outward pulling rope body 8 are connected to the connecting pieces on the outer walls of the rotating pressing pieces 6 of the same group, so that the two rotating pressing pieces 6 of the same group can be synchronously rotated outward by pulling the outward pulling rope body 8.

[0037] The outward pulling rope body 8 is a hard rubber rope body, and the outer edge of the outward pulling rope body 8 extends beyond the edge of the anti-collision patch 4. The outward pulling rope body 8 cooperates with the anti-collision patch 4 to form an outer protection ring on the outer side of the base ring 1 and the outer edge of the opposing fitting mechanism, which can further prevent the protruding opposing fitting mechanism from scratching the newborn.

[0038] The locking mechanism includes a positioning rotating frame 103 and a locking belt 104. The positioning rotating frame 103 is rotatably installed at the end of one of the opening and closing side rings 102, and the locking belt 104 is arranged at the end of the other opening and closing side ring 102. A through groove is formed on the positioning rotating frame 103, and Velcro for adhesion is provided on the body and end of the locking belt 104, so that the end of the locking belt 104 can pass through the through groove of the positioning rotating frame 103 and then adhere to the body of the locking belt 104 to achieve end-to-end adhesion. By adjusting the adhesion position of the locking belt 104, the length after the connection of the positioning rotating frame 103 and the locking belt 104 can be controlled, thereby controlling the distance between the ends of the two opening and closing side rings 102, and achieving the effect of controlling the tightness of the ring body of the base ring 1.

[0039] In this embodiment, during use, first pull the two opening and closing side rings 102 to open. At this time, pulling the outer pull rope body 8 drives the two rotating pressing pieces 6 on the same opening and closing side ring 102 to rotate outwards, allowing the newborn's hand to pass through the shielding ring 3. After releasing the outer pull rope body 8, under the torsion of the torsion spring 7, the rotating pressing piece 6 rotates inwards and passes through the through groove on the opening and closing side ring 102, squeezing both sides of the pulse measurement belt 2 on the inner wall of the opening and closing side ring 102, so that the pulse measurement belt 2 fits on the newborn's wrist. Then, pull the locking belt 104 to pass through the through groove of the positioning rotating frame 103 and then adhere to the body of the locking belt 104, so that the base ring 101 and the opening and closing side ring 102 surround the outside of the newborn's wrist. The base ring 1 is locked outside the newborn's wrist through the locking mechanism, forming a fixed position for the whole. Then, through the opposing fitting mechanisms on the base ring 101 and the opening and closing side ring 102 respectively, the shielding ring 3 inside the base ring 101 and the pulse measurement belt 2 inside the opening and closing side ring 102 are respectively squeezed to surround and fit on the outside of the newborn's wrist, forming targeted point-by-point squeezing and fixing, thereby forming an all-round fixing of the belt body fitting the newborn's wrist from point to surface. At this time, the pulse measurement belt 2 and the shielding ring 3 form a circumferential pulse measurement sleeve at the newborn's wrist, while the base ring 101 and the opening and closing side ring 102 form a protective ring belt outside the measurement sleeve. The anti-collision patch 4 and the outer pull rope body 8 form another protective belt to prevent the newborn from bumping on the outside of the ring belt. On the premise of stably fixing the pulse measurement sleeve, protection is formed outside the fixed measurement sleeve to prevent the newborn's arm from moving randomly and hitting himself.

[0040] Embodiment 2

[0041] As Figures 1-6 shown, this embodiment is basically the same as Embodiment 1. Preferably, in order to prevent the measured belt body from scratching the wrist when the newborn moves around and protect the newborn, a multi-directional limiting component 9 is arranged at the concave part of the opening and closing side ring 102, and a clamping piece 10 for buckling in the limiting component 9 is arranged on the outer arc surface of the pulse measurement belt 2.

[0042] The limiting component 9 includes a horizontal limiting block 901 and a vertical limiting block 902. The horizontal limiting block 901 includes two horizontally arranged limiting blocks with opposite openings, and the vertical limiting block 902 includes two vertically arranged limiting blocks with opposite openings. The horizontal limiting block 901 and the vertical limiting block 902 are both arranged at the concave center of the opening and closing side ring 102, and the four limiting blocks are arranged in a surrounding manner. The clamping piece 10 is a cross-shaped sheet body, and the four corners of the clamping piece 10 can be respectively inserted into the four surrounding limiting blocks.

[0043] The distance between the two limiting blocks of the horizontal limiting block 901 is greater than the length of the horizontal sheet body of the clamping piece 10, and the distance between the two limiting blocks of the vertical limiting block 902 is greater than the length of the vertical sheet body of the clamping piece 10. When the clamping piece 10 is inserted into the four limiting blocks, there is a certain movement gap in all four directions. When the pulse measurement belt 2 is attached to the outside of the newborn's wrist under the extrusion of the opposing attachment mechanism, the distance between the clamping piece 10 and the limiting component 9 can ensure that there is a certain movement space for the pulse measurement belt 2 inside the opening and closing side ring 102. When the newborn's arm moves randomly, the friction between the pulse measurement belt 2 and the wrist can be reduced.

[0044] In this embodiment, after the pulse measurement belt 2 and the shielding ring 3 are doubly fixed to the newborn's wrist by using the base ring 1 and the opposing attachment mechanism, through the movement space between the horizontal limiting block 901 and the vertical limiting block 902 inside the opening and closing side ring 102 of the clamping piece 10 on the outside of the pulse measurement belt 2, when the newborn's arm moves randomly, a certain movement space can be formed for the base ring 1 on the outside of the wrist, preventing the base ring 1 from driving the inner pulse measurement belt 2 and the shielding ring 3 to shift and rub against the newborn's wrist when the newborn's arm moves randomly, and better protecting the newborn.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
