Problems solved by technology

[0005] However, the current market lacks a device that can wind medical catheters before assembly. In order to apply the device for automatically winding medical catheters to the winding of medical catheters before assembly, the problems that need to be solved are: 1. The coil winding device does not have a tensioning mechanism for tensioning the medical catheter, and the medical catheter is relatively loose after coiling, which is not conducive to subsequent feeding and assembly; 2. The original coil device drives the mandrel up and down through the cylinder to make the tubular medical tube The device is detached from the positioning block, and this blanking method cannot meet the needs of subsequent assembly

Embodiment 1

[0051] The medical catheter winding device is used for winding the medical catheter, which facilitates the subsequent assembly of the medical catheter and saves the space required for assembly. The medical catheter winding device comprises a support seat 1, a turntable body 2, a positioning seat 3, a chuck 8, a tensioning mechanism and a driving mechanism.

[0052] Specifically, as figure 1 and Figure 9 As shown, the positioning seat 3 is symmetrically arranged on the turntable body 2, and each positioning seat 3 has a support rod 31 for supporting the medical catheter. In this embodiment, a fixed seat 4 is provided between the turntable body 2 and the positioning seat 3, and the turntable body 2 has a chute 2a corresponding to the position and shape of the fixed seat 4, and the fixed seat 4 can slide relative to the chute 2a Or it is positioned with the slide groove 2a through screw connection, which is suitable for winding medical catheters of different diameters or diffe...

Embodiment 2

[0059] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, such as Figure 7 As shown, the tension mechanism includes a support platform 9 positioned on the support base 1 and a tension clamp 15 arranged on the support platform 9. The tension clamp 15 is driven by the driving source 22 and drives its two ends to open or In the closing action, the two ends of the tension clamp 15 are respectively provided with freely rotatable runners 16. Driven by the drive source 22, the two runners 16 approach each other so that the runners 16 wheel surfaces are pressed against the medical catheter. Or move away from each other to make the running wheel 16 wheel surfaces unclamp the motion of the medical catheter. In this embodiment, the tension clamp 15 includes an active clamp 151 and a passive clamp 152 that both can rotate around the support platform 9 , and the active clamp 151 can drive th...

Embodiment 3

[0063] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1 or Embodiment 2. The difference is that in this embodiment, the driving mechanism includes a rotating shaft 17 fixed on the turntable body 2 and a rotating shaft 17 fixed on the support platform 9. The ejector rod, driving source 4 and driving source 5 on the top, the rotating shaft 17 is connected with the output shaft of the driving source 4, the ejector rod is connected with the piston rod of the driving source 5, and the driving source 4 drives the turntable body 2 to rotate, and the driving source 5 drives the support platform 9 rise or fall corresponding height. The rotation of the turntable body 2 and the lifting of the support platform 9 are controlled by the control unit, which facilitates the adjustment of linkage parameters and meets the needs of different winding densities of medical catheters.

[0064] In the actual manufacturing process, motor, air mot...

Abstract

The invention provides a medical catheter winding device, and belongs to the technical field of medical equipment production equipment. The medical catheter winding device solves the problem that when an existing medical catheter winding device is used for winding a medical catheter, the catheter is loose after being wound. The medical catheter winding device comprises a supporting base and a rotary disk body which is axially located on the supporting base. Two locating bases are arranged on the rotary disk body, both the locating bases are provided with supporting rods used for supporting the medical catheter, the rotary disk body is further provided with a chuck used for clamping the end portion of the medical catheter and a tensioning mechanism used for enabling the catheter to be kept in a tight state when the catheter is wound and a driving mechanism used for driving the rotary disk body to rotate and meanwhile driving the rotary disk body and the tensioning mechanism to rise or fall relatively are arranged on the supporting base. Due to the fact that the medical catheter is provided with the tensioning mechanism, the medical catheter is kept in the tight state in the whole winding process and accordingly the medical catheter which is wound is made to be tight and firm.

Description

technical field [0001] The invention belongs to the technical field of medical device production equipment, and relates to a winding device, in particular to a medical catheter winding device. Background technique [0002] The infusion set is a kind of commonly used medical apparatus and instruments, and it generally comprises medical conduit, is connected with piercer, drip funnel, flow regulator and liquid medicine filter on the medical conduit. In the current production process of the infusion set, the puncture device, the drip funnel, the flow regulator and the liquid medicine filter are usually firstly assembled on the medical catheter respectively, and then wound and sealed for packaging after leak testing. [0003] With the emergence of mechanized and automated infusion set assembly equipment, the automatic winding of the assembled infusion set gradually replaces the original manual winding, which improves the production efficiency of the infusion set and avoids secon...
