Description

Technical Field

[0001] This utility model relates to the field of infusion set drip assembly technology, and in particular to an air-blowing infusion set drip assembly device. Background Technology

[0002] During the production of air-blowing infusion sets, connecting tubes need to be assembled at both ends of the drip chamber to facilitate subsequent connection of the infusion tubing. However, common drip chambers are usually made of flexible and easily deformable materials. Due to the lack of an effective support structure during assembly, the drip chamber is prone to collapse and deformation under pressure. This collapse and deformation not only leads to deviations in component installation positions, increases assembly difficulty, and reduces production efficiency, but also affects the sealing effect of the drip chamber assembly position, thus compromising the practicality of the air-blowing infusion set drip chamber assembly device. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an air-blowing infusion drip assembly device that uses air pressure to keep the drip in a taut state, reduces the possibility of the drip collapsing and deforming under pressure during the assembly process, improves the convenience of assembling the two ends of the drip, and uses air inflation to simultaneously detect whether there is air leakage at the drip assembly point.

[0004] This utility model also provides an assembly device for a blow-type infusion set drip chamber, comprising: a base plate, on the upper surface of which a cylinder, a pad, and a rubber block are fixedly connected; an installation tube is fixedly connected to the output end of the cylinder; a blower is fixedly connected to the surface of the installation tube; and an air guide tube is fixedly connected to the outlet of the blower. When using the device, the right end of the air guide tube passes through the assembly component with the drip chamber and enters the interior of the drip chamber. The upper surface of the pad and the left surface of the rubber block are respectively provided with a groove and a socket hole. A vertical plate is fixedly connected to the front and rear surfaces of the pad. A pressure plate is slidably connected to the upper end of the vertical plate. A liquid storage box is fixedly connected to the upper surface of the pressure plate, and a flow guide tube is fixedly connected to the lower surface of the liquid storage box.

[0005] According to the present invention, in the assembly device for an air-blowing infusion set drip chamber, there is a damping force at the sliding point between the pressure plate and the upright plate. When using the device, the lower surface of the pressure plate contacts the side surface of the drip chamber without applying pressure to it. This improves the effectiveness of the pressure plate.

[0006] According to the present invention, the width of the guide tube in the air-blowing infusion set drip assembly device is greater than the diameter of the drip pot, and when using the device, the guide tube is located directly above the drip pot assembly node. This improves the effectiveness of the guide tube.

[0007] According to the present invention, a hot air box is fixedly connected to the upper surface of the base plate of an air-blowing infusion drip chamber assembly device, and the hot air box is located between the cylinder and the pad block. This improves the convenience of drying the drip chamber.

[0008] According to the present invention, a filter plate is fixedly connected inside the hot air box of an air-blowing infusion set drip chamber. The filter plate is tilted to the lower right to improve the contact effect between the drip chamber and the hot air.

[0009] According to the present invention, the hot air box of the air-blowing infusion set drip chamber assembly device consists of a box body and a hot air blower, and the installation location of the hot air blower is separated from the filter plate, with the air outlet of the hot air blower extending through to the filter plate installation location. This facilitates the maintenance of the hot air box.

[0010] According to the present invention, an arc plate is fixedly connected to the right inner wall of the filter plate mounting location in the air-blowing infusion drip assembly device. The arc plate is distributed opposite to the air outlet of the hot air blower, thereby improving the flow of hot air.

[0011] According to the present invention, the front, rear, left, and right surfaces of the housing of the air-blowing infusion set / drip container assembly device are provided with heat dissipation holes, which are interconnected with the hot air blower mounting location, thereby improving the heat dissipation efficiency of the hot air blower.

[0012] Beneficial effects:

[0013] Compared with existing technologies, this air-blowing infusion set drip chamber assembly device uses an automatic telescopic rod, installation tube, blower, air guide tube, rubber pad, groove, rubber block, and socket hole to seal the unassembled end of the drip chamber during assembly. It also uses continuous air blowing to keep the flexible drip chamber taut, reducing the possibility of the drip chamber collapsing and deforming under pressure. At the same time, the continuous air blowing, in conjunction with the liquid storage box, tests the airtightness of the assembly point while assembling the drip chamber. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses an assembly device for an air-blowing infusion set drip chamber, comprising: a base plate 1, a cylinder 2, a pad 3, and a rubber block 4 fixedly connected to the upper surface of the base plate 1; an installation tube 7 fixedly connected to the output end of the cylinder 2; the cylinder 2 provides a thrust to the installation tube 7 to approach the drip chamber; a blower 8 is fixedly connected to the surface of the installation tube 7; and an air guide tube 11 is fixedly connected to the outlet of the blower 8. When using the device, the right end of the air guide tube 11 passes through the assembly component with the drip chamber and enters the interior of the drip chamber. The blower 8 cooperates with the air guide tube 11 to fill the interior of the drip chamber with gas, ensuring that the drip chamber always remains in an expanded and taut state, thereby improving the pressure resistance of the drip chamber. The upper surface of the pad 3 and the left surface of the rubber block 4 are respectively provided with a groove 13 and a socket hole 14. The groove 13 and the socket hole 14 cooperate to increase the convenience of placing the drip chamber. At the same time, the socket hole 14 and the rubber block 4 cooperate to seal one end of the unassembled component of the drip chamber, thereby improving the sealing of the drip chamber during the assembly process.

[0023] Specifically, the dripper is placed in the groove 13 and pushed to the right into the socket 14. At this time, the opening on the right end of the dripper is sealed by the rubber block 4. Then, the component assembled with the dripper is inserted into the surface of the air guide tube 11. At this time, the output end of the cylinder 2 extends and drives the mounting tube 7 to move to the right. Therefore, the assembly component fixed to the surface of the air guide tube 11 gradually approaches the dripper. After the docking component contacts the dripper, the blower 8 is turned on to fill the inside of the dripper with gas, keeping it in an expanded and taut state to increase the dripper's pressure resistance.

[0024] A vertical plate 5 is fixedly connected to the front and rear surfaces of the pad 3. A pressure plate 15 is slidably connected to the upper end of the vertical plate 5. There is a damping force at the sliding point between the pressure plate 15 and the vertical plate 5. When using the device, the lower surface of the pressure plate 15 contacts the side surface of the drip pot, and no pressure is applied to the drip pot. The pressure plate 15 is used to limit the vertical range of motion of the drip pot and reduce the negative impact of blowing air. A liquid storage box 16 is fixedly connected to the upper surface of the pressure plate 15. A guide tube 17 is fixedly connected to the lower surface of the liquid storage box 16. The width of the guide tube 17 is greater than the diameter of the drip pot. When using the device, the guide tube 17 is located directly above the drip pot assembly node. The liquid storage box 16 cooperates with the guide tube 17 to judge the airtightness of the drip pot splice by adding water. The liquid storage box 16 stores soap water inside.

[0025] Specifically, after the dripper is placed on the surface of the pad 3, the pressure plate 15 is pressed down to make the pressure plate 15 contact the surface of the dripper. At this time, the assembly work can be carried out. After the assembly part is fixed, the guide tube 17 is opened to let the soap water inside the liquid storage box 16 fall to the assembly node. The assembly node is observed to see if there are air bubbles by re-inflating the dripper, so as to test the airtightness of the assembly node. Excess soap water inside the groove 13 flows out through the left side.

[0026] A hot air box 6 is fixedly connected to the upper surface of the base plate 1. The hot air box 6 is located between the cylinder 2 and the pad 3. The hot air box 6 consists of a box body 18 and a hot air blower 19. The hot air box 6 is used to dry the soapy water on the surface of the dripping pot. The temperature of the hot air blower 19 is controlled within 40-60℃ to avoid damage to the dripping pot due to heating. The installation location of the hot air blower 19 is separated from the filter plate 10. The air outlet of the hot air blower 19 extends through to the installation location of the filter plate 10. The front, back, left, and right surfaces of the box body 18 are provided with heat dissipation holes 9. The heat dissipation holes 9 are connected to the installation location of the hot air blower 19. The parts are interconnected, and the heat dissipation holes 9 increase the heat dissipation efficiency of the hot air blower 19. A filter plate 10 is fixedly connected inside the hot air box 6. The filter plate 10 is tilted to the lower right. The filter plate 10 uses its own holes to increase the contact effect between the dripper and the hot air. At the same time, the tilted structure of the filter plate 10 prevents the dripper from contacting the air outlet of the hot air blower 19 when there is too much dripping. A circular arc plate 12 is fixedly connected to the right inner wall of the filter plate 10. The circular arc plate 12 is distributed opposite to the air outlet of the hot air blower 19. The circular arc plate 12 improves the gas dispersion effect.

[0027] Specifically, after the dripper is assembled, the friction between the air guide tube 11 and the inner wall of the assembled component causes the dripper to be moved to the left by the installation tube 7. When the dripper moves away from the pad 3 and moves above the filter plate 10, the dripper is manually blocked to separate from the installation tube 7. At this time, the dripper falls into the hot air box 6 and comes into contact with the hot air blown out by the hot air blower 19, thereby drying the water stains on the surface of the dripper. At the same time, after the dripper falls and collides with the filter plate 10, some of the water stains on its surface are separated by stress and fall into the interior of the box 18.

[0028] Working principle: The dripper and assembly parts are added to the designated position. After applying epoxy resin adhesive to the surface of the assembly parts, the cylinder 2 is used to move the assembly parts closer to the dripper. After the assembly parts are close to the dripper, the blower 8 is turned on to fill the dripper with gas. Since the air guide tube 11 can pass through the assembly parts and enter the dripper, the gas blown out by the air guide tube 11 cannot affect the adhesive on the surface of the assembly parts. After the assembly parts are completely spliced ​​with the dripper and the two are fixed by adhesive, soapy water is applied to the assembly joint, and the dripper is blown with air again. The airtightness of the assembly is checked by observing whether bubbles are generated in the soapy water. Finally, the assembled dripper is put into the hot air box 6 for water storage and drying.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
