Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheter processing, in particular to a side hole punching device for urinary catheter processing. Background Art

[0002] A urinary catheter is a medical device, usually made of a flexible tubular material, used to drain urine from the bladder to the outside of the body. The end of the catheter body is provided with a side hole for drainage.

[0003] If the edge of the side hole is not smooth, it will directly affect the harm to the patient during use. Conventionally, a flat knife is used to process the side hole of the catheter tube body. When the knife moves forward to cut and form the side hole, it often causes certain burrs, and some burrs face outward. Some smaller burrs are easily overlooked during the inspection process. In addition, the inner diameter of the tube body of some small-sized catheters is small, and it is easy to penetrate the entire tube body during the side hole drilling process. Ultimately, all of these will affect the quality of the product. Utility Model Content

[0004] The utility model aims to provide a side hole punching device for processing a urinary catheter, which has the function of improving the processing quality of the product.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a side hole punching device for processing a urinary catheter, comprising a base, a bottom plate vertically arranged on the base, a base arranged on the bottom plate, a sliding seat arranged on the base for horizontal sliding, a first cylinder arranged between the base and the sliding seat and driving the sliding seat to move, a mounting seat arranged on the sliding seat, a tool arranged on the mounting seat, a processing mold arranged on the base and for the end of the catheter to be embedded, an electric heating ring arranged on the base and for heating the end of the tool, and an electric heating ring arranged between the base and the sliding seat and for limiting the bottom. The invention relates to a limiting mechanism for the sliding stroke of the seat; the processing mold is provided with a mounting hole for the end of the tube body of the catheter to be embedded, and the processing mold is provided with a hole groove which is communicated with the mounting hole and for the tool to enter, and the tool is aligned with the hole groove; the limiting mechanism includes an "L"-shaped bracket arranged on the upper surface of the sliding seat, a first limiting screw arranged on the bracket, and a limiting arm arranged at one end of the sliding seat away from the processing mold, the piston rod of the first cylinder is connected to the limiting arm, and when the sliding seat moves toward the direction close to the processing mold, the end of the first limiting screw is used to press against the upper end of the limiting arm to achieve limiting.

[0006] By adopting the above technical solution, when drilling the side hole, first insert the end of the catheter into the installation hole, and drive the tool on the sliding seat to move in the direction close to the processing mold through the cylinder. Because the tool is heated by the electric heating ring, the tool can directly heat and melt away the fine burrs in the process of drilling the side hole, so that the edge of the drilled side hole is inward and the outer wall of the tube body is smooth to the touch, thereby improving the processing quality of the product; at the same time, the sliding stroke of the sliding seat is limited by the setting of the limiting mechanism, thereby avoiding the situation where the tool penetrates the tube body.

[0007] The utility model is further configured as follows: a fixed vertical plate for mounting the first cylinder is arranged on the base, the middle part of the tool is fixed on the mounting seat, and the rear end of the tool is provided with a guide shaft passing through the fixed vertical plate during the movement of the sliding seat.

[0008] By adopting the above technical solution, first, the middle part of the tool is fixed on the mounting seat so that the joining point between the tool and the mounting seat is located in the middle of the tool to reduce the shaking of the tool during the movement of the sliding seat; at the same time, a guide shaft passing through the fixed vertical plate is set at the rear end of the tool to improve the stability of the tool during movement.

[0009] The utility model is further configured as follows: the limiting mechanism also includes a second limiting screw rod arranged on the upper end of the fixed vertical plate, and when the sliding seat moves in a direction away from the processing mold, the end of the second limiting screw rod is used to press against the limiting arm for limiting.

[0010] By adopting the above technical solution, the formation during the resetting process of the sliding seat can be limited by limiting the second limiting screw.

[0011] The utility model is further configured as follows: the base is lifted and lowered on a bottom plate, a second cylinder for driving the base to be lifted and lowered is provided between the bottom plate and the base, two mounting holes distributed up and down are provided on the processing mold, and two hole grooves corresponding to the mounting holes are provided on the processing mold.

[0012] By adopting the above technical solution, two mounting holes are provided for the catheter to be embedded, so that after the processing of the catheter in one mounting hole is completed, the tool can process the catheter in another mounting hole. At this time, the operator has enough time to remove the catheter in the previous mounting hole and install a new unprocessed catheter, which has the effect of improving work efficiency.

[0013] The utility model is further configured as follows: a projection range of the electric heating coil projected onto the processing mold along the horizontal direction covers two holes, and the electric heating coil is provided with a three-quarter circle wrapping portion at positions corresponding to the two holes, and the electric heating coil is close to the processing mold.

[0014] By adopting the above technical solution, when the tool is processing the catheter corresponding to the two mounting holes, the lifting and lowering of the tool will not interfere with the electric heating coil. At this time, the tool only needs to move a small stroke when resetting, so that the end of the tool can be heated by the electric heating coil. The setting of the wrapping part can achieve uniform heating of the tool. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Embodiment: A side hole punching device for processing a urinary catheter, such as Figure 1 As shown, it includes a base 1, a bottom plate 2 vertically arranged on the base 1, a base 3 arranged on the bottom plate 2, a sliding seat 4 arranged on the base 3 for transverse sliding, a first cylinder 5 arranged between the base 3 and the sliding seat 4 and driving the sliding seat 4 to move, a mounting seat 6 arranged on the sliding seat 4, a tool 7 arranged on the mounting seat 6, a processing mold 8 arranged on the base 1 and for the end of the catheter body to be embedded, an electric heating coil 9 arranged on the base 1 and for heating the end of the tool 7, and a limiting mechanism arranged between the base 3 and the sliding seat 4 and limiting the sliding stroke of the base 3.

[0021] like Figure 1 As shown, the processing mold 8 is provided with a mounting hole 81 for the end of the catheter to be embedded in, and the processing mold 8 is provided with a hole groove 82 which is connected with the mounting hole 81 and for the tool 7 to enter, and the tool 7 is aligned with the hole groove 82.

[0022] like Figure 1As shown, the limiting mechanism includes an "L"-shaped bracket 101 arranged on the upper surface of the sliding seat 4, a first limiting screw 102 arranged on the bracket 101, a limiting arm 103 arranged at the end of the sliding seat 4 away from the processing mold 8, and a second limiting screw 104 arranged at the upper end of the fixed vertical plate 11. The piston rod of the first cylinder 5 is connected to the limiting arm 103. When the sliding seat 4 moves toward the direction close to the processing mold 8, the end of the first limiting screw 102 is used to press against the upper end of the limiting arm 103 to achieve limiting; when the sliding seat 4 is reset in the direction away from the processing mold 8, the end of the second limiting screw 104 is used to press against the limiting arm 103 to achieve limiting.

[0023] like Figure 1 As shown, a fixed vertical plate 11 for mounting the first cylinder 5 is provided on the base 1, the middle part of the tool 7 is fixed on the mounting seat 6, and the rear end of the tool 7 is provided with a guide shaft 12 that passes through the fixed vertical plate 11 during the movement of the sliding seat 4.

[0024] Implementation effect: When drilling the side hole, first insert the end of the catheter into the mounting hole 81, and drive the tool 7 on the sliding seat 4 to move toward the direction close to the processing mold 8 through the cylinder. Because the tool 7 is heated by the electric heating ring 9, the tool 7 can directly heat and melt away the fine burrs during the process of drilling the side hole, so that the edge of the drilled side hole faces inward and the outer wall of the tube body is smooth to the touch, thereby improving the processing quality of the product; at the same time, the sliding stroke of the sliding seat 4 is limited by the setting of the limiting mechanism, thereby preventing the tool 7 from penetrating the tube body.

[0025] First, the middle of the tool 7 is fixed on the mounting seat 6, so that the joint point of the tool 7 and the mounting seat 6 is located in the middle of the tool 7 to reduce the vibration of the tool 7 during the movement of the sliding seat 4; at the same time, a guide shaft 12 passing through the fixed vertical plate 11 is arranged at the rear end of the tool 7 to improve the stability of the tool 7 during the movement. By limiting the second limiting screw 104, the formation of the sliding seat 4 during the resetting process can be limited.

[0026] Embodiment 2: A side hole punching device for processing a urinary catheter, such as Figure 2 and Figure 3 As shown, the difference from Example 1 is that the base 3 is set on the bottom plate 2 for lifting, a second cylinder 13 for driving the base 3 to lift is arranged between the bottom plate 2 and the base 3, two mounting holes 81 distributed up and down are arranged on the processing mold 8, and two hole grooves 82 corresponding to the mounting holes 81 are arranged on the processing mold 8. The projection range of the electric heating coil 9 projected onto the processing mold 8 in the horizontal direction covers the two hole grooves 82, and the positions of the electric heating coil 9 corresponding to the two hole grooves 82 are respectively provided with a three-quarter circle wrapping portion 91, and the electric heating coil 9 is close to the processing mold 8.

[0027] Implementation effect: By providing two mounting holes 81 for the catheter to be embedded, after the catheter in one mounting hole 81 is processed, the cutter 7 can process the catheter in another mounting hole 81. At this time, the operator has enough time to remove the catheter in the previous mounting hole 81 and install a new unprocessed catheter, which improves work efficiency.

[0028] At this time, when the tool 7 is processing the catheter corresponding to the two mounting holes 81, the lifting and lowering of the tool 7 will not interfere with the electric heating coil 9. At this time, the tool 7 only needs to move a small stroke when resetting, so that the end of the tool 7 can be heated by the electric heating coil 9. The setting of the wrapping portion 91 can achieve uniform heating of the tool 7.

[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
