Description

Technical Field

[0001] The present invention relates to the field of medical device manufacturing, in particular to a urinary catheter cannula machine. Background Art

[0002] A urinary catheter is primarily used to drain urine from the body, greatly helping people with physical disabilities and incontinence. It is widely used in medicine. A urinary catheter is a tube made of rubber, silicone, or plastic that can be inserted into the bladder through the urethra to drain urine. It primarily consists of a balloon cuff and a drainage tube. After insertion, the balloon cuff near the tip of the catheter is inflated, expanding the cuff and securing the catheter within the bladder, preventing it from being removed. The drainage tube has a balloon hole. An elastic balloon cuff is placed over the balloon hole in the drainage tube and then sealed with glue at both ends to form a balloon cavity. In existing technology, the balloon cuff is typically manually expanded and inserted into the drainage tube, then secured and sealed with glue. This results in low production efficiency. Inaccurate insertion positioning can result in misalignment between the balloon hole and the cuff, while difficulty accurately controlling the glue application range can easily result in an undersized balloon cavity. Ultimately, the balloon may not fully inflate or even fail to inflate, rendering it ineffective. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a catheter sleeve machine that can improve the assembly efficiency of the air bag sleeve and the drainage tube.

[0004] The embodiment of the present invention discloses a urinary catheter sheath machine, comprising: a machine platform; a driving device mounted on the machine platform; an air bag sleeve expansion and fixing device, comprising an expansion mechanism and a fixing mechanism, both of which are movably mounted on the machine platform, the driving device being capable of driving the expansion mechanism and the fixing mechanism to move toward or away from each other, the expansion mechanism being capable of expanding the air bag sleeve, and the fixing mechanism being capable of clamping and fixing the expanded air bag sleeve on the drainage tube; a drainage tube positioning and adjustment device movably mounted on the machine platform and located on one side of the air bag sleeve expansion and fixing device, the drainage tube positioning and adjustment device comprising a pin mechanism, the expansion mechanism and / or the fixing mechanism being provided with a first through hole for the pin mechanism to pass through, the driving device being capable of driving the pin mechanism to move, thereby driving the drainage tube to move; a glue dispensing device mounted on the machine platform, the glue dispensing device being capable of dispensing glue on the drainage tube after the pin mechanism drives the drainage tube to move below the glue dispensing device.

[0005] The catheter sheath machine according to the embodiment of the present invention has at least the following beneficial effects: an airbag sheath expansion and fixing device, a drainage tube positioning and adjustment device, and a glue dispensing device are provided, and the driving device is used to automatically complete the assembly steps of expanding the airbag sheath, positioning the drainage tube, glue dispensing and sealing, and inserting the airbag sheath, thereby significantly improving the assembly efficiency between the airbag sheath and the drainage tube.

[0006] According to some embodiments of the present invention, the first through-hole is provided on the expansion mechanism, and the fixing mechanism is provided with a second through-hole for the drainage tube to pass through. By providing the first through-hole on the expansion mechanism, the ejector mechanism positions the end of the drainage tube fixed to the expansion mechanism, which expands the airbag cuff, thereby minimizing the relative positional error between the airbag cuff and the drainage tube. Providing the second through-hole on the fixing mechanism for the drainage tube to pass through fully utilizes the device space, avoiding the need for the fixing mechanism to avoid the drainage tube, which would increase the device size.

[0007] According to some embodiments of the present invention, the drive device includes a first drive mechanism, a second drive mechanism, and a third drive mechanism. A guide rail is mounted on the machine platform, and the first drive mechanism, the second drive mechanism, and the third drive mechanism are capable of respectively driving the expansion mechanism, the fixing mechanism, and the ejector mechanism to move forward and backward along the guide rail. By providing separate drive mechanisms to drive the movement of each mechanism, the equipment achieves a higher degree of automation, which is beneficial for enhancing equipment control capabilities and improving assembly efficiency.

[0008] According to some embodiments of the present invention, the drive device further includes a fourth drive mechanism capable of driving the dispensing head of the dispensing device to move up and down toward or away from the drainage tube. Providing the fourth drive mechanism to drive the dispensing head allows the dispensing head to be positioned close to the drainage tube during dispensing, thereby improving dispensing quality and preventing the dispensing head from colliding with the drainage tube and damaging parts during further assembly processes.

[0009] According to some embodiments of the present invention, the expansion mechanism includes a first drive unit and an expansion unit, the expansion unit including at least three expansion arms, the first drive unit being capable of driving the at least three expansion arms to move to expand the airbag cuff, and the fixing mechanism including a second drive unit and a fixing unit, the fixing unit including at least three fixing arms, the fixing arms being parallel to and facing the expansion arms, and the second drive unit being capable of driving the at least three fixing arms to move to clamp and fix the expanded airbag cuff to the drainage tube. The first drive unit is configured to drive the expansion unit to move to expand the airbag cuff, and the second drive unit is configured to drive the fixing unit to move to clamp and fix the expanded airbag cuff to the drainage tube. When the expansion arms release the airbag cuff, the airbag cuff remains in a clamped and fixed state, thereby reducing positional errors of the airbag cuff after it is attached to the drainage tube.

[0010] According to some embodiments of the present invention, the first drive unit includes a first mounting plate, a first drive member, and a first transmission unit. The first mounting plate is movably disposed on the machine platform. The first drive member and the first transmission unit are both mounted on the first mounting plate. The expansion arm is connected to the first transmission unit. The first drive member can drive at least three expansion arms to slide toward or away from each other on the first mounting plate through the first transmission unit. By configuring the first drive unit as the first mounting plate, the first drive member, and the first transmission unit, the first drive member can simultaneously control at least three expansion arms to slide toward or away from each other on the first mounting plate through the first transmission unit, thereby completing the steps of expanding and releasing the airbag cover. The position error of the expansion and release processes is small and the efficiency is high.

[0011] According to some embodiments of the present invention, the second drive unit includes a second mounting plate, a second drive member, and a second transmission unit. The second mounting plate is movably mounted on the machine platform. The second drive member and the second transmission unit are both mounted on the second mounting plate. The fixed arm is connected to the second transmission unit. The second drive member can drive at least three fixed arms to slide toward or away from each other on the second mounting plate via the second transmission unit. By configuring the second drive unit as the second mounting plate, the second drive member, and the second transmission unit, the second drive member can simultaneously control at least three fixed arms to slide toward or away from each other on the second mounting plate via the second transmission unit, thereby completing the step of clamping the airbag cover. The position error of the airbag cover clamping process is small and the efficiency is high.

[0012] According to some embodiments of the present invention, the ejector mechanism includes an ejector and an abutment portion, wherein the abutment portion is capable of abutting against the end face of the drainage tube, and the ejector can be inserted into the drainage tube to drive the movement of the drainage tube. Providing the ejector pin to drive the movement of the drainage tube, and providing the abutment portion to abut against the end face of the drainage tube, can improve the ejector mechanism's ability to position the drainage tube and reduce assembly errors.

[0013] According to some embodiments of the present invention, the drainage tube positioning and adjustment device further includes a fifth drive mechanism capable of driving the ejector pin to rotate, thereby driving the drainage tube to rotate. By adding a fifth drive mechanism to drive the ejector pin to rotate the drainage tube, the glue dispensing device can more evenly dispense glue onto the drainage tube, thereby improving the sealing effect between the airbag sleeve and the drainage tube.

[0014] Some embodiments of the present invention further include a control device mounted on the machine platform and electrically connected to the drive device, the airbag cuff expansion and fixing device, the drainage tube positioning and adjustment device, and the glue dispensing device. By centrally controlling the drive device, the airbag cuff expansion and fixing device, the drainage tube positioning and adjustment device, and the glue dispensing device through the control device, operation is simplified and user-friendly, the probability of misoperation is reduced, and the qualified rate of finished products is improved.

[0033] Reference Figures 1 to 5The present invention discloses a urinary catheter cannula machine for assembling an airbag cuff 700 on a drainage tube 800, comprising a machine platform 100, a driving device 200, an airbag cuff expansion and fixing device 300, a drainage tube positioning and adjustment device 400, and a glue dispensing device 500. The driving device 200 is mounted on the machine platform 100. The airbag cuff expansion and fixing device 300 comprises an expansion mechanism 310 and a fixing mechanism 320, both of which are movably mounted on the machine platform 100. The driving device 200 can drive the expansion mechanism 310 and the fixing mechanism 320 to move toward or away from each other, so that the expansion mechanism 310 can expand the airbag cuff 700, and the fixing mechanism 320 can clamp and fix the expanded airbag cuff 700 on the drainage tube 800. The drainage tube positioning and adjustment device 400 is movably mounted on the machine 100 and located to one side of the airbag sleeve expansion and fixing device 300. The drainage tube positioning and adjustment device 400 includes a pin mechanism 410. The expansion mechanism 310 and / or the fixing mechanism 320 are provided with a first through-hole 311 for the pin mechanism 410 to pass through. The driving device 200 is capable of driving the pin mechanism 410 to move, thereby driving the drainage tube 800. The glue dispensing device 500 is mounted on the machine 100. After the pin mechanism 410 drives the drainage tube 800 to move below the glue dispensing device 500, the glue dispensing device 500 can dispense glue on the drainage tube 800. The assembly process of the airbag cover 700 and the drainage tube 800 begins with the expansion mechanism 310 expanding the airbag cover 700. Next, the drainage tube 800 is inserted into the airbag cover 700. At this point, the ejector mechanism 410 moves forward through the first through-hole 311 to secure the drainage tube 800. The ejector mechanism 410 continues its forward movement, driving the drainage tube 800. After the predetermined glue dispensing position on the drainage tube 800 moves to below the glue dispensing device 500, the glue dispensing device 500 dispenses glue onto the drainage tube 800. After dispensing, the ejector mechanism 410 pulls the drainage tube 800 back, aligning the dispensed position with the airbag cover 700. The securing mechanism 320 then moves backward, causing the securing arms 322 to clamp and deform the airbag cover 700, partially pressing the airbag cover 700 against the drainage tube 800. Finally, the expansion arm 312 is released from the airbag sleeve 700, and the airbag sleeve 700 is completely attached to the drainage tube 800. The glue between the airbag sleeve 700 and the drainage tube 800 seals the ends of the airbag sleeve 700, completing the assembly process of the airbag sleeve 700 and the drainage tube 800. The airbag sleeve expansion and fixing device 300, the drainage tube positioning and adjustment device 400, and the glue dispensing device 500 are provided. Driven by the driving device 200, the assembly steps of expanding the airbag sleeve 700, positioning the drainage tube 800, applying glue and sealing, and inserting the airbag sleeve 700 are automatically completed, thereby significantly improving the assembly efficiency between the airbag sleeve 700 and the drainage tube 800.

[0034] Reference Figure 2 、 Figure 3In certain embodiments of the present invention, a first through-hole 311 is provided on the expansion mechanism 310, and a second through-hole 321 is provided on the fixing mechanism 320 for passage of the drainage tube 800. In this case, the corresponding drainage tube positioning and adjustment device 400 is provided on a side adjacent to the expansion mechanism 310, with the expansion mechanism 310 located between the drainage tube positioning and adjustment device 400 and the fixing mechanism 320. By providing the first through-hole 311 on the expansion mechanism 310, the end of the drainage tube 800 fixed by the ejector mechanism 410 is positioned close to the expansion mechanism 310 that expands the airbag cuff 700, minimizing the relative positional error between the airbag cuff 700 and the drainage tube 800. Providing the second through-hole 321 on the fixing mechanism 320 for passage of the drainage tube 800 can fully utilize the equipment space and avoid increasing the equipment size due to the fixing mechanism 320 avoiding the drainage tube 800.

[0035] It is conceivable that the first through hole 311 for the ejector mechanism 410 to pass through can also be provided on the fixing mechanism 320, and the second through hole 321 for the drainage tube 800 to pass through can be provided on the expansion mechanism 310. At this time, the drainage tube positioning and adjustment device 400 is provided on the side close to the fixing mechanism 320, which can also play the role of making way for the ejector mechanism 410 and the drainage tube 800 to avoid the equipment being larger in size.

[0036] Reference Figures 3 to 5 In certain embodiments of the present invention, the drive device 200 includes a first drive mechanism 210, a second drive mechanism 220, and a third drive mechanism 230. A guide rail 110 is mounted on the machine platform 100 and arranged parallel to the front-to-back direction. The first drive mechanism 210, the second drive mechanism 220, and the third drive mechanism 230 can respectively drive the expansion mechanism 310, the fixing mechanism 320, and the ejector mechanism 410 to move forward and backward along the guide rail 110. By providing separate drive mechanisms to drive the movement of each mechanism, the equipment achieves a higher degree of automation, which helps enhance equipment control capabilities and improve assembly efficiency.

[0037] Reference Figures 3 to 5 In certain embodiments of the present invention, the drive device 200 further includes a fourth drive mechanism 240, which is capable of driving the dispensing head of the dispensing device 500 to move up and down toward or away from the drainage tube 800. Providing the fourth drive mechanism 240 to drive the dispensing head movement improves the dispensing quality by allowing the dispensing head to be positioned close to the drainage tube 800 during the dispensing process, while also preventing the dispensing head from colliding with the drainage tube 800 and potentially damaging parts during the assembly process.

[0038] Reference Figures 3 to 5In some embodiments of the present invention, the first drive mechanism 210, the second drive mechanism 220, and the fourth drive mechanism 240 are all cylinders. Using cylinders as drive mechanisms has a simple structure and low energy consumption during the drive process, which can reduce costs.

[0039] In certain embodiments of the present invention, the first drive mechanism 210, the second drive mechanism 220, the third drive mechanism 230, and the fourth drive mechanism 240 may also be electric cylinders or hydraulic cylinders. Using electric cylinders as drive mechanisms improves drive precision, while using hydraulic cylinders as drive mechanisms increases output force, enabling rapid movement of the expansion mechanism 310, the fixing mechanism 320, the ejector mechanism 410, and the dispensing head of the dispensing device 500.

[0040] Reference Figure 6 、 Figure 7 In certain embodiments of the present invention, the expansion mechanism 310 includes a first drive unit and five expansion units, each of which includes three expansion arms 312. The first drive unit is capable of driving at least three expansion arms 312 to expand the airbag cuff 700. The fixing mechanism 320 includes a second drive unit and five fixing units, each of which includes three fixing arms 322. The second drive unit is capable of driving at least three fixing arms 322 to clamp and secure the expanded airbag cuff 700 to the drainage tube 800. The first drive unit is configured to drive the expansion unit to expand the airbag cuff 700, and the second drive unit is configured to drive the fixing unit to clamp and secure the expanded airbag cuff 700 to the drainage tube 800 of the urinary catheter. When the expansion arms 312 release the airbag cuff 700, the airbag cuff 700 remains clamped and secured, thereby reducing positional errors after the airbag cuff 700 is attached to the drainage tube 800.

[0041] Reference Figure 6 In certain embodiments of the present invention, the first drive unit includes a first mounting plate 315, a first drive member (not shown), and a first transmission unit 313. The first mounting plate 315 is movably mounted on the machine 100. The first drive member and the first transmission unit 313 are both mounted on the first mounting plate 315. The expansion arms 312 are connected to the first transmission unit 313. The first drive member, through the first transmission unit 313, can drive at least three expansion arms 312 to slide toward or away from each other on the first mounting plate 315. By configuring the first drive unit as the first mounting plate 315, the first drive member, and the first transmission unit 313, the first drive member, through the first transmission unit 313, can simultaneously control the at least three expansion arms 312 to slide toward or away from each other on the first mounting plate 315, thereby completing the steps of deploying and releasing the airbag cover 700. Positional errors during the deployment and release processes are minimized and efficiency is high.

[0042] Reference Figure 6 In certain embodiments of the present invention, the first mounting plate 315 is provided with first chutes 314 that correspond one-to-one with the expansion arms 312. In this embodiment, three expansion arms 312 correspond to three first chutes 314, with one end of each first chute 314 oriented toward the expansion center of the expansion unit. The first chutes 314 allow the expansion arms 312 to slide along the first chutes 314, moving toward or away from the expansion center of the expansion unit. The first chutes 314 restrict the sliding direction of the expansion arms 312, allowing the expansion arms 312 to expand or contract the airbag cover 700 more smoothly and with less positioning error.

[0043] Reference Figure 6 In some embodiments of the present invention, the first transmission unit 313 includes a first driving gear 3131, a first rack 3132, a first driven gear 3133 and a first connecting member (not shown in the figure) corresponding to the expansion arm 312. The first rack 3132 is respectively engaged with the first driving gear 3131 and the first driven gear 3133. The first driving gear 3131 is movably connected to the first driving member. The first driven gear 3133 is provided with a first arc groove (not shown in the figure) corresponding to the expansion arm 312. One end of the first connecting member passes through the first arc groove and is connected to the expansion arm 312. The rotation of the first driven gear 3133 can drive the first connecting member to slide along the first arc groove, thereby driving the expansion arm 312 to slide along the first sliding groove 314. The first driving gear 3131 rotates to drive the first rack 3132 to move, thereby driving the first arc groove on the first driven gear 3133 to rotate, causing the first connecting member to slide relative to the first arc groove, and also driving the expansion arm 312 to slide along the first sliding groove 314. The structure is relatively simple and the transmission is effective.

[0044] Reference Figure 7 In certain embodiments of the present invention, the second drive unit includes a second mounting plate 325, a second drive member (not shown), and a second transmission unit 323. The second mounting plate 325 is movably mounted on the machine 100. The second drive member and the second transmission unit 323 are both mounted on the second mounting plate 325. The fixed arms 322 are connected to the second transmission unit 323. The second drive member, through the second transmission unit 323, can drive at least three fixed arms 322 to slide toward or away from each other on the second mounting plate 325. By configuring the second drive unit as the second mounting plate 325, the second drive member, and the second transmission unit 323, the second drive member, through the second transmission unit 323, can simultaneously control the at least three fixed arms 322 to slide toward or away from each other on the second mounting plate 325, thereby completing the step of clamping the airbag cover 700. This process of clamping the airbag cover 700 results in minimal positional error and high efficiency.

[0045] Reference Figure 7In certain embodiments of the present invention, the second mounting plate 325 is provided with second sliding grooves 324 that correspond one-to-one with the fixed arms 322. In this embodiment, three fixed arms 322 correspond to three second sliding grooves 324, with one end of each second sliding groove 324 facing the clamping center of the fixed unit. The second sliding grooves 324 allow the fixed arms 322 to slide along the second sliding grooves 324, moving toward or away from the clamping center of the fixed unit. The second sliding grooves 324 restrict the sliding direction of the fixed arms 322, allowing the fixed arms 322 to clamp the airbag cover 700 more smoothly and with less positioning error.

[0046] Reference Figure 7 In some embodiments of the present invention, the second transmission unit 323 includes a second driving gear 3231, a second rack 3232, a second driven gear 3233 and a second connecting member (not shown in the figure) corresponding to the fixed arm 322. The second rack 3232 is respectively engaged with the second driving gear 3231 and the second driven gear 3233. The second driving gear 3231 is movably connected to the second driving member. The second driven gear 3233 is provided with a second arc groove (not shown in the figure) corresponding to the fixed arm 322. One end of the second connecting member passes through the second arc groove and is connected to the fixed arm 322. The rotation of the second driven gear 3233 can drive the second connecting member to slide along the second arc groove, thereby driving the fixed arm 322 to slide along the second sliding groove 324. The second rack 3232 is driven to move by the rotation of the second driving gear 3231, which in turn drives the second arc groove on the second driven gear 3233 to rotate, causing the second connecting member to slide relative to the second arc groove, and also drives the fixed arm 322 to slide along the second sliding groove 324. The structure is relatively simple and the transmission is effective.

[0047] Reference Figure 8 In certain embodiments of the present invention, the ejector mechanism 410 includes an ejector 411 and an abutting portion 412. The abutting portion 412 can abut against the end surface of the drainage tube 800. The ejector 411 can be inserted into the drainage tube 800 to drive the movement of the drainage tube 800. The insertion of the ejector 411 into the drainage tube 800 to drive the movement of the drainage tube 800, coupled with the abutting portion 412 abutting against the end surface of the drainage tube 800, can improve the ejector mechanism 410's ability to position the drainage tube 800 and reduce assembly errors.

[0048] Reference Figure 8In certain embodiments of the present invention, the drainage tube positioning and adjustment device 400 further includes a fifth drive mechanism 420, which comprises a third drive member (not shown), a third driving gear 421, a third rack 422, a third driven gear 423, and a third mounting plate 424. The third mounting plate 424 is movably mounted on the machine 100, and the third driving gear 421, the third rack 422, and the third driven gear 423 are all movably mounted on the third mounting plate 424. The third rack 422 meshes with the third driving gear 421 and the third driven gear 423, respectively. The third drive member is connected to the third driving gear 421, and the third driven gear 423 is connected to the ejector mechanism 410. When the third drive member drives the third driving gear 421 to rotate, the third driving gear 421 drives the third driven gear 423 to rotate via the third rack 422, ultimately driving the ejector mechanism 410 to rotate. The rotation of the ejector 411 of the ejector mechanism 410 then drives the drainage tube 800 to rotate. By adding a fifth driving mechanism 420 to drive the ejector pin 411 to rotate the drainage tube 800, the glue dispensing device 500 can evenly dispense glue on the drainage tube 800, which helps to improve the sealing effect between the airbag cover 700 and the drainage tube 800.

[0049] Reference Figure 1 In certain embodiments of the present invention, a control device 600 is further included. The control device 600 is mounted on the machine 100 and is electrically connected to the drive device 200, the airbag cuff expansion and fixing device 300, the drainage tube positioning and adjustment device 400, and the glue dispensing device 500. Centrally controlling the drive device 200, the airbag cuff expansion and fixing device 300, the drainage tube positioning and adjustment device 400, and the glue dispensing device 500 through the control device 600 makes operation simpler and more user-friendly, reduces the probability of misoperation, and improves the yield rate of finished products.

[0050] Reference Figure 1 In some embodiments of the present invention, a dust cover 120 is further included. The dust cover 120 is provided to at least partially cover the control device 600, the drive device 200, the airbag sleeve expansion and fixing device 300, the drainage tube positioning and adjustment device 400, and the dispensing device 500, thereby protecting them from dust and ensuring reliable operation of the device.
