Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a blood collection device for newborn disease screening. Background Technology

[0002] Because the environment in which newborns grow and develop in the womb is complex, some congenital metabolic diseases, endocrine disorders or other serious illnesses often lack obvious external symptoms at birth and are difficult to detect in a timely manner through routine examinations.

[0003] However, traditional blood collection devices mostly rely on restraint straps or simple fixation frames. These fixation methods not only fail to provide a stable and reliable fixation effect, but also make it easy for the blood collection position to shift if the newborn struggles even slightly, seriously affecting the efficiency and accuracy of blood collection; moreover, if the restraint force is not properly controlled, an overly tight restraint can cause marks or even damage to the newborn's delicate skin.

[0004] At the same time, existing blood collection devices generally lack the function of heating the blood collection site. Since newborns have a weak ability to regulate their own body temperature, their blood vessels will constrict in a low-temperature environment, which undoubtedly increases the difficulty of blood collection, prolongs the blood collection time, and thus brings more unnecessary pain and discomfort to newborns.

[0005] Furthermore, from a structural design perspective, the device lacks flexibility. Existing blood collection devices are difficult to adjust in height and angle according to actual operational needs, failing to adequately accommodate the operating habits of different medical personnel and the individual differences in body size and position of newborns, resulting in numerous inconveniences during practical use. Therefore, there is an urgent need to design a blood collection device for newborn disease screening to address these issues.

[0006] Invention Content The purpose of this invention is to provide a blood collection device for newborn disease screening to address the aforementioned shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A blood collection device for newborn disease screening includes a base and an installation assembly. A fixing assembly is provided on the bottom inner wall of the base. The fixing assembly includes a miniature air pump bolted to the bottom inner wall. An air delivery pipe is provided on the top of the miniature air pump. A branch pipe is provided at one end of the air delivery pipe. Fixing rings are provided at both ends of the branch pipe. An air bag is provided on one side of the fixing ring. The mounting assembly includes a mounting plate located above the base, and a driving assembly is provided at the bottom of the mounting plate. The driving assembly includes an electric telescopic rod II bolted to the bottom of the mounting plate. A fixing block is fixedly connected to the output end of the electric telescopic rod II. A connecting plate is provided on one side of the fixing block, and fixing plates are provided at both ends of the connecting plate.

[0008] Preferably, the base has a plurality of support legs at its bottom, and the bottom of each support leg is provided with an anti-slip pad.

[0009] Preferably, a rotating seat is provided on both sides of the bottom of the mounting plate, and a connecting rod is provided between the rotating seats, the connecting rod passing through the rotating seats and connecting to the base.

[0010] Preferably, the mounting plate is provided with telescopic rods on both sides of its bottom, and the mounting plate is connected to the base through the telescopic rods. The mounting plate is provided with slide groove one and slide groove two on both sides of its top.

[0011] Preferably, a fixed base is provided on one side of the mounting plate, and an electric telescopic rod is provided at the bottom of the fixed base. The electric telescopic rod is fixedly connected to the base, and the electric telescopic rod is used at least to lift one side of the mounting plate.

[0012] Preferably, a heating assembly is provided on the top of the mounting plate. The heating assembly includes a mounting base slidably connected to the top of the heating assembly. A heating element is provided on the outer wall of the mounting base, and locking nuts are provided on both sides of the top of the mounting base.

[0013] Preferably, the micro air pump is equipped with a one-way valve at its outlet, the air supply pipe and branch pipe are both made of flexible rubber, and the inner wall of the airbag is provided with a soft silicone pad.

[0014] Preferably, the heating element is a PTC constant temperature heating element, and the heating temperature range is set to 32-37℃.

[0015] Preferably, the travel range of the electric telescopic rod is 5-15cm, and its output end is connected to the fixed base via a ball joint, wherein the rotation angle range of the ball joint is 0-30°.

[0017] In the above technical solution, the blood collection device for newborn disease screening provided by the present invention has the following beneficial effects: (1) Through the coordinated operation of the micro air pump, air delivery tube, branch tube, fixing ring and air bag in the fixing component, flexible fixation of the newborn's limbs is achieved. The micro air pump can inflate the air bag as needed and flexibly adjust the air bag pressure, which can effectively prevent the newborn's limbs from shaking and affecting the blood collection operation, and avoid injury to the newborn caused by rigid restraint. At the same time, the soft silicone pad layer on the inner wall of the air bag further enhances the newborn's comfort experience.

[0030] like Figure 1-7 As shown in the figure, an embodiment of the present invention provides a blood collection device for newborn disease screening, including a base 1 and an installation assembly 3. A fixing assembly 4 is provided on the bottom inner wall of the base 1. The fixing assembly 4 includes a miniature air pump 41 bolted to the bottom inner wall. An air supply pipe 42 is provided on the top of the miniature air pump 41. A branch pipe 43 is provided at one end of the air supply pipe 42. Fixing rings 44 are provided at both ends of the branch pipe 43. An air bag 45 is provided on one side of the fixing ring 44. The installation assembly 3 includes an installation plate 31 located above the base 1. A driving assembly 7 is provided at the bottom of the installation plate 31. The driving assembly 7 includes an electric telescopic rod 71 bolted to the bottom of the installation plate 31. A fixing block 72 is fixedly connected to the output end of the electric telescopic rod 71. A connecting plate 73 is provided on one side of the fixing block 72. Fixing plates 74 are provided at both ends of the connecting plate 73.

[0031] Specifically, in this embodiment, it includes a base 1 and a mounting component 3. A fixing component 4 is provided on the bottom inner wall of the base 1. The base 1 is in the shape of a rectangular frame, and its bottom inner wall serves as the mounting base for the fixing component 4, providing stable support for the entire device. The fixing component 4 includes a miniature air pump 41 bolted to the inner wall of the bottom. The miniature air pump 41 is vertically fixed to one side of the inner wall of the bottom of the base 1 by bolts to ensure the stability during operation. The top of the miniature air pump 41 is provided with an air supply pipe 42, and one end of the air supply pipe 42 is provided with a branch pipe 43. The top of the miniature air pump 41 is vertically connected to the air supply pipe 42. After the air supply pipe 42 extends upward to the middle of the hollow area inside the base 1, the branch pipe 43 is horizontally provided. The branch pipe 43 has a "Y" shaped structure, and both ends are connected to the fixing ring 44 respectively. Both ends of the branch pipe 43 are provided with fixing rings 44. The fixing rings 44 are semi-circular metal structures and are fixed to both ends of the branch pipe 43 by welding. One side of the fixing rings 44 is tightly attached to the airbag 45, and the airbag 45 is provided on one side of the fixing rings 44. The airbag 45 is attached to the fixing rings 44 with strong glue. When the miniature air pump 41 is started, compressed air enters the air bag 45 through the air supply pipe 42 and the branch pipe 43, causing the air bag 45 to inflate, thereby fixing the external object. Mounting assembly 3 includes a mounting plate 31 located above the base 1. The mounting plate 31 is a rectangular metal plate. A driving assembly 7 is provided at the bottom of the mounting plate 31. The driving assembly 7 includes an electric telescopic rod 71 bolted to the bottom of the mounting plate 31. A fixing block 72 is fixedly connected to the output end of the electric telescopic rod 71. The output end of the electric telescopic rod 71 extends horizontally toward the base 1 and is fixedly connected to the fixing block 72 by high-strength screws. A connecting plate 73 is provided on one side of the fixing block 72, and fixing plates 74 are provided at both ends of the connecting plate 73. The fixing block 72 is a cube structure, and one side of it is connected to the connecting plate 73 by welding. The connecting plate 73 is long and strip-shaped, and the fixing plates 74 are welded perpendicularly to both ends. When the electric telescopic rod 71 extends or retracts, it can drive the fixing block 72, the connecting plate 73 and the fixing plate 74 to move horizontally, thereby realizing the movement of the fixing ring 44 and realizing flexible adjustment of the fixing component 4 for different lengths.

[0032] Specifically, in this invention, the bottom of the base 1 is provided with a plurality of support legs 2, and the bottom of the support legs 2 is provided with anti-slip pads. The support legs 2 are vertically arranged at the four corners of the bottom of the base 1. The support legs 2 are cylindrical metal rods, and the bottom of them are connected to the anti-slip pads by threads. The anti-slip pads are made of rubber and have uneven textures on the surface, which can increase the friction with the ground and prevent the device from sliding during use.

[0033] Specifically, in this invention, rotating seats 32 are provided on both sides of the bottom of the mounting plate 31, and a connecting rod 33 is provided between the rotating seats 32. The rotating seats 32 are U-shaped metal structures and are fixed to the bottom of the mounting plate 31 by welding. The connecting rod 33 is horizontally arranged between the rotating seats 32, and both ends of the connecting rod 33 pass through circular through holes on the rotating seats 32 and are connected to the rotating seats 32 by bearings, so that the connecting rod 33 can rotate freely within the rotating seats 32. The connecting rod 33 passes through the rotating seat 32 and is connected to the base 1. At the same time, after passing through the rotating seat 32, the connecting rod 33 is fixed to the top two sides of the base 1 by welding, thereby realizing the rotational connection between the mounting plate 31 and the base 1, so that the mounting plate 31 can be rotated around the connecting rod 33 at a certain angle.

[0034] Specifically, in this invention, telescopic rods 36 are provided on both sides of the bottom of the mounting plate 31. The mounting plate 31 is connected to the base 1 through the telescopic rods 36. The telescopic rods 36 are multi-stage sleeve structures. One end is fixed to the bottom of the mounting plate 31 by welding, and the other end is connected to the top of the base 1 by welding. During the operation of the device, the telescopic rods 36 can extend and retract with the movement of the mounting plate 31, playing a supporting and guiding role. The top two sides of the mounting plate 31 are provided with slide groove 1 34 and slide groove 2 37 respectively. Both slide groove 1 34 and slide groove 2 37 are provided on the top two sides of the mounting plate 31. Both are arranged parallel to the length direction of the mounting plate 31. The drive component 7 is slidably connected to the fixed component 4 through slide groove 1 34, and the heating component 6 is slidably connected to slide groove 2 37.

[0035] Specifically, in this invention, a fixed seat 35 is provided on one side of the mounting plate 31, and an electric telescopic rod 5 is provided at the bottom of the fixed seat 35. The electric telescopic rod 5 is fixedly connected to the base 1, and the electric telescopic rod 5 is used at least to lift one side of the mounting plate 31. When the electric telescopic rod 5 extends, it can push the fixed seat 35, thereby causing one side of the mounting plate 31 to flip upward around the connecting rod 33, thus adjusting the tilt angle. Since the output end of the electric telescopic rod 5 is connected to the fixed seat 35 through a ball joint, and the rotation angle range of the ball joint is 0-30°, the electric telescopic rod 5 can flexibly adjust the angle within a certain range when pushing the fixed seat 35, avoiding motion interference caused by angle limitation.

[0036] Specifically, in this invention, a heating component 6 is provided on the top of the mounting plate 31. The heating component 6 includes a mounting seat 61 slidably connected to the top of the heating component 6. The mounting seat 61 has a semi-circular ring structure, and a slider matching the second slide groove 37 is provided at its bottom. Through the sliding connection between the slider and the second slide groove 37, the mounting seat 61 can slide freely on the top of the mounting plate 31 along the direction of the second slide groove 37. The outer wall of the mounting base 61 is provided with a heating element 62. The heating element 62 is installed on the outer wall of the mounting base 61 by means of a slot and screw. The heating element 62 is a PTC constant temperature heating element with a heating temperature range of 32-37℃, which can stably provide a suitable temperature. Locking nuts 63 are provided on both sides of the top of the mounting base 61. When the mounting base 61 slides to the appropriate position, the mounting base 61 can be fixed on the mounting plate 31 by tightening the locking nuts 63.

[0037] Specifically, in this invention, a one-way valve is provided at the air outlet of the micro air pump 41. The function of the one-way valve is to prevent compressed air from flowing back and to ensure the normal inflation and fixation effect of the airbag 45. Both the gas supply pipe 42 and the branch pipe 43 are made of flexible rubber, which allows them to deform flexibly with the movement of the components during the movement of the device, avoiding damage to the pipes due to rigid connections. The inner wall of the airbag 45 is provided with a soft silicone pad. The soft silicone pad can prevent damage to the surface of the object when the airbag 45 inflates and fixes the object.

[0038] Specifically, in this invention, the heating element 62 is a PTC constant temperature heating element, and the heating temperature range is set to 32-37℃.

[0039] Specifically, in this invention, the travel range of the electric telescopic rod 5 is 5-15cm, and the tilt angle of the mounting plate 31 can be adjusted according to actual usage needs. Its output end is connected to the fixed base 35 through a ball joint, and the rotation angle range of the ball joint is 0-30°.
