Description

Technical Field

[0001] This invention belongs to the field of blood collection technology, and in particular relates to a fluid-carrying mobile peripheral blood collection mechanism. Background Technology

[0002] Blood tests are a common medical procedure used in hospitals to diagnose and treat patients. For adults, most blood draws are now done using vacuum blood collection tubes or disposable syringes for venous blood collection. For infants and the elderly, due to their thinner blood vessels or limited mobility, capillary blood is often collected. Capillary blood collection involves puncturing the blood with a needle, allowing the blood to flow through the collection tube. This is done by squeezing and releasing the balloon to allow the capillary blood to enter. To prevent blood from being expelled during a second collection, the inner end of the collection tube is usually inserted into the balloon a short distance, forming a reservoir where the blood is stored. However, this structure makes it difficult to quickly and easily expel the blood from the reservoir. It requires squeezing the lower edge of the balloon to compress the reservoir, making the procedure inconvenient and inefficient. Therefore, the structure needs to be upgraded to allow for more convenient and efficient blood drainage. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a fluid-carrying mobile peripheral blood collection mechanism that allows for convenient and efficient drainage of blood.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A fluid-carrying mobile capillary blood collection mechanism includes a collection cylinder, a collection airbag, a fluid-carrying plate, a telescopic sealing sleeve, a rotating ring, and a blood collection tube. A blood collection tube is fixedly installed in the lower center of the collection cylinder. The fluid-carrying plate is installed inside the lower part of the collection cylinder. The middle sealing sleeve of the fluid-carrying plate is connected to the outer periphery of the blood collection tube. The telescopic sealing sleeve is installed inside the middle of the collection cylinder, with its upper periphery connected to the collection cylinder and its lower periphery connected to the upper periphery of the fluid-carrying plate. The upper end of the blood collection tube is located within the telescopic sealing sleeve. Inside; the upper end of the collection tube is provided with a vent opening, which is located in the middle of the upper end of the telescopic sealing sleeve. The collection airbag is installed at the upper end of the collection tube and is connected to the vent opening; a rotating ring is rotatably installed around the upper outer periphery of the collection tube, and the rotation of the rotating ring drives the liquid-carrying plate to move up and down; when the liquid-carrying plate moves downward, the outer periphery of the collection tube, the liquid-carrying plate, and the telescopic sealing sleeve form a liquid storage cavity; when the liquid-carrying plate moves upward, the upper end of the collection tube is distributed in the middle of the liquid-carrying plate, and the upper end of the collection tube is sealed to the liquid-carrying plate.

[0005] Furthermore, a venting tube is fixedly inserted into the venting opening of the collection tube, and an annular connecting plate is provided around the upper end of the venting tube, with a collection airbag installed at the upper end of the annular connecting plate.

[0006] Furthermore, it also includes a moving mechanism; the moving mechanism includes an inner gear block, a rotating rod, a threaded ring, and a lifting screw; a lifting screw is installed on each of the upper two sides of the liquid-carrying plate; the inner two ends of the rotating ring are respectively meshed with the inner gear block; a rotating rod is installed on the lower end of the inner gear block, the rotating rod rotates through the collection tube, and the lower end of the rotating rod is connected to the threaded ring; the threaded ring is threadedly screwed to the lifting screw.

[0007] Furthermore, a limiting moving block is provided on the outer side of the lifting screw; a limiting moving groove is provided on both sides of the inside of the collection tube; the limiting moving block is slidably engaged with the limiting moving groove.

[0008] Furthermore, the lower end of the rotating rod is provided with a connecting block, and the two sides of the lower end of the connecting block are connected to threaded rings through fixing rods.

[0009] Furthermore, the lower end of the rotating ring is provided with locking blocks on both sides; the upper end of the collection tube is provided with an annular groove; the rotating ring is rotatably locked onto the annular groove through the locking blocks.

[0010] Furthermore, the blood collection tube is made of a polymer material.

[0011] Furthermore, the liquid-carrying plate has a through hole in the middle, and a sealing ring is provided on the through hole; the blood collection tube is inserted into the through hole and its outer sides are sealed and abutted against the sealing ring.

[0012] Furthermore, the telescopic sealing sleeve is made of bellows or elastic material.

[0013] The beneficial effects of this invention are as follows: This invention utilizes a collection balloon that is squeezed to expel airflow. The lower end of the blood collection tube then contacts the capillary blood. Releasing the collection balloon allows the capillary blood to flow through the blood collection tube into the collection cylinder. The blood then enters a reservoir surrounded by the outer perimeter of the blood collection tube, a liquid-carrying plate, and a telescopic sealing sleeve. This design ensures the blood is positioned around the upper perimeter of the blood collection tube. During secondary collection, squeezing the collection balloon prevents blood from entering the reservoir and is thus avoided. To expel blood from the reservoir, a rotating ring is rotated. This rotation drives an inner gear block, which in turn drives a threaded ring via a rotating rod. The threaded ring's rotation moves a lifting screw upwards, which in turn moves the liquid-carrying plate upwards. This positions the upper end of the blood collection tube within the liquid-carrying plate, sealing it in place. This upward compression of the reservoir until it disappears, simultaneously causing the blood to move upwards. Squeezing the collection balloon again allows for efficient blood expulsion, making the invention flexible and convenient to use. Attached Figure Description

[0018] The invention will now be described in further detail with reference to the accompanying drawings.

[0019] like Figures 1 to 4As shown, a fluid-carrying mobile capillary blood collection mechanism includes a collection cylinder 1, a collection airbag 2, a fluid-carrying plate 3, a telescopic sealing sleeve 4, a rotating ring 5, and a blood collection tube 6. A blood collection tube 6 is fixedly installed in the lower center of the collection cylinder 1. The fluid-carrying plate 3 is installed inside the lower part of the collection cylinder 1. The middle sealing sleeve of the fluid-carrying plate 3 is connected to the outer periphery of the blood collection tube 6.

The collection airbag 2 is installed on the upper end of the collection tube 1 and is connected to the vent opening 11. A rotating ring 5 is rotatably installed around the upper outer periphery of the collection tube 1. The rotating ring 5 drives the liquid-carrying plate 3 to move up and down. When the liquid-carrying plate 3 moves downward, the outer periphery of the collection tube 6, the liquid-carrying plate 3, and the telescopic sealing sleeve 4 form a liquid storage cavity 7. When the liquid-carrying plate 3 moves upward, the upper end of the collection tube 6 is distributed in the middle of the liquid-carrying plate 3, and the upper end of the collection tube 6 is sealed to the liquid-carrying plate 3.

[0020] like Figures 1 to 4 As shown, in order to facilitate the connection between the collection airbag 2 and the collection tube 1, a ventilation tube 8 is fixedly inserted into the ventilation opening 11 of the collection tube 1. An annular connecting plate 81 is provided around the upper end of the ventilation tube 8, and the collection airbag 2 is installed at the upper end of the annular connecting plate 81.

[0021] like Figures 1 to 4 As shown, in order to facilitate the control of the liquid-carrying plate 3's up-and-down movement by rotating ring 5, a moving mechanism 9 is further included; the moving mechanism 9 includes an inner gear block 91, a rotating rod 92, a threaded ring 93, and a lifting screw 94; a lifting screw 94 is installed on each of the upper two sides of the liquid-carrying plate 3; the inner two ends of the rotating ring 5 are respectively meshed with the inner gear block 91; a rotating rod 92 is installed on the lower end of the inner gear block 91, the rotating rod 92 is rotatably connected to the collection tube 1, and the lower end of the rotating rod 92 is connected to the threaded ring 93; the threaded ring 93 is threadedly screwed to the lifting screw 94.

[0022] like Figures 1 to 4 As shown, in order to ensure the stable up and down movement of the lifting screw 94, a limiting moving block 941 is provided on the outer side of the lifting screw 94; a limiting moving groove 12 is provided on both sides of the inside of the collection cylinder 1; the limiting moving block 941 is slidably engaged with the limiting moving groove 12.

[0023] like Figures 1 to 4As shown, in order to facilitate the connection between the rotating rod 92 and the threaded ring 93, the lower end of the rotating rod 92 is provided with a connecting block 921, and the threaded ring 93 is connected to both sides of the lower end of the connecting block 921 through a fixing rod 922.

[0024] like Figures 1 to 4 As shown, in order to ensure stable rotation of the rotating ring 5, locking blocks 51 are provided on both sides of the lower end of the rotating ring 5; annular grooves 13 are provided around the upper end of the collection tube 1; the rotating ring 5 is rotatably locked onto the annular grooves 13 by the locking blocks 51. Furthermore, the blood collection tube 6 is made of polymer material.

[0025] like Figures 1 to 4 As shown, to ensure a sealed connection between the liquid-carrying plate 3 and the blood collection tube 6, the liquid-carrying plate 3 is further provided with a through hole 31 in the middle, and a sealing ring 32 is provided on the through hole 31; the blood collection tube 6 passes through the through hole 31 and its outer sides are sealed and abut against the sealing ring 32. Furthermore, the telescopic sealing sleeve 4 is made of corrugated pipe or elastic material.

[0026] This invention involves squeezing the collection airbag 2 to expel airflow, then contacting the lower end of the blood collection tube 6 with capillary blood, and releasing the collection airbag 2. This allows capillary blood to enter the collection cylinder 1 through the blood collection tube 6, and into the reservoir 7 formed by the outer periphery of the blood collection tube 6, the liquid-carrying plate 3, and the telescopic sealing sleeve 4. This ensures the blood is positioned around the upper periphery of the blood collection tube 6. Therefore, during secondary collection, squeezing the collection airbag 2 prevents blood from entering the blood collection tube 6 from the reservoir 7, avoiding the expulsion of blood. When it is necessary to drain the blood from the reservoir 7, it can be... Rotating the rotating ring 5 causes the inner gear block 91 to rotate. The inner gear block 91, through the rotating rod 92, causes the threaded ring 93 to rotate. The rotation of the threaded ring 93 causes the lifting screw 94 to move upward. The lifting screw 94 causes the liquid-carrying plate 3 to move upward, so that the upper end of the blood collection tube 6 is distributed in the middle of the liquid-carrying plate 3, and the upper end of the blood collection tube 6 is sealed to the liquid-carrying plate 3. This causes the liquid storage chamber 7 to be compressed upward until it disappears, and at the same time, the blood moves upward. Thus, when the collection airbag 2 is squeezed, the blood can be smoothly discharged, making it flexible and convenient to use.
