Description

Technical Field

[0001] The present application relates to the technical field of medical needle tube processing, and in particular to a tool for processing a side wall groove of a safety needle tube. Background Art

[0002] Medical safety needles and syringes are a common basic medical device. Compared with ordinary needles and syringes, safety needles and syringes can provide higher safety protection. After the ordinary needles and syringes are used, the needles of ordinary needles and syringes have no protective measures and may accidentally stab the staff or patients during the handling process, causing skin damage or bleeding. If the needle has been contaminated with bacteria and viruses during previous use, then the stab injury may cause cross infection. At the same time, if protective measures such as paper sleeves or sleeves are not used, the needle will accumulate dust when in contact with the external environment, resulting in an increased risk of needle contamination, which may pose a threat to the patient's health when used. The needles of safety needles and syringes are usually stored in paper sleeves or sleeves before and after use, thereby reducing the risk of injury and infection that may be caused by the needle.

[0003] At present, some paper covers or sleeves installed on the needle heads of safety needles on the market usually have no fixing measures, which makes the paper covers or sleeves easily fall off the needle heads of safety needles, increasing the risk of using the safety needle tubes. In order to facilitate the fixing of the paper covers or sleeves, grooves are usually provided on the side walls of the safety needle tubes. However, in the process of processing the grooves on the side walls of the safety needle tubes, the processing is difficult and the cost of existing production equipment is relatively high.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a tool for processing the side wall groove of a needle tube of a safety needle.

[0032] Example 1

[0033] Reference Figure 1 A tooling for processing the side wall groove of a safety needle tube includes a mounting seat 1, a processing device 2 for clamping and processing the safety needle tube, and a mounting frame 3 for mounting the mounting seat 1. The mounting frame 3 includes a bottom plate 31, a guide rod 32 fixedly connected to the side of the mounting seat 1 away from the bottom plate 31, and a top plate 33 fixedly connected to the side of the guide rod 32 away from the bottom plate 31; the processing device 2 includes a clamping block 21 slidably connected to the side of the mounting seat 1 away from the bottom plate 31, a punch 22 set on the clamping block 21 for processing the groove, and a driving assembly 23 for driving the clamping block 21 to move. The clamping blocks 21 are relatively arranged with two blocks, and the punches 22 are correspondingly arranged with two blocks, and the two punches 22 are relatively arranged on the opposite sides of the two clamping blocks 21. The punches 22 are hemispherical, and the two punches 22 are located on the same horizontal plane. During processing, the staff places the mounting frame 3 on the stamping device, and drives the driving assembly 23 to move through the stamping device. The stamping device is the same as the existing equipment, and this application will not elaborate on it in detail.

[0034] During use, the staff places the safety needle tube to be processed between the two clamping blocks 21, and the limiting device 4 limits the two ends of the safety needle tube, so that the position of the safety needle tube during processing is more secure. After the safety needle tube to be processed is placed, the staff operates to install the mounting frame 3 on the stamping die, and connects the stamping head with the driving component 23, so that under the action of the stamping head, the driving component 23 drives the two clamping blocks 21 to move toward each other, and the punch 22 abuts against the side wall of the safety needle tube. As the clamping block 21 moves, the punch 22 gradually squeezes the side wall of the safety needle tube, so that a groove is formed on the side wall of the safety needle tube, thereby improving the processing efficiency of the groove on the side wall of the safety needle tube.

[0035] Reference Figure 1 The clamping block 21 includes a moving block 211 and an abutting block 212 fixedly connected to one side of the moving block 211. A first extrusion surface 213 is provided on the side of the moving block 211 away from the mounting seat 1. The first extrusion surface 213 is inclined from top to bottom, and the inclined surface of the first extrusion surface 213 faces the side of the moving block 211 away from the abutting block 212. The cross section of the abutting block 212 is an isosceles triangle, the vertex of the triangle is located on the side of the abutting block 212 away from the moving block 211, the punch 22 is located at the end of the abutting block 212 away from the moving block 211, and the moving block 211 and the abutting block 212 are integrally formed.

[0036] In order to reduce the impact of the side of the abutting block 212 away from the moving block 211 on the workers or the side wall of the safety needle tube during the processing operation, the end of the abutting block 212 away from the moving block 211 is set as an arc surface 214.

[0037] Reference Figure 1 and Figure 2 The driving assembly 23 includes a connecting tube 231, a driving plate 232, an extrusion block 233 fixedly connected to the side of the driving plate 232 close to the mounting seat 1, and a positioning block 234 for limiting the position of the extrusion block 233. Among them, one end of the connecting tube 231 is fixedly connected to the side of the driving plate 232 away from the mounting seat 1, and the other end is penetrated through the top plate 33; two positioning blocks 234 are relatively arranged, and the positioning blocks 234 are located on the side of the moving block 211 away from the abutting block 212, and the two positioning blocks 234 are symmetrically arranged along the central axis of the long side of the mounting seat 1; two extrusion blocks 233 are arranged, and the side of the extrusion block 233 close to the mounting seat 1 is inclinedly arranged with a second extrusion surface, and the inclined surface of the second extrusion surface faces the side of the abutting block 212. Under normal conditions, the second extrusion surface abuts on the first extrusion surface 213, and the side of the extrusion block 233 away from the moving block 211 abuts against the side wall of the positioning block 234, and the guide rod 32 is penetrated through the driving plate 232 to guide the moving direction of the driving plate 232.

[0038] When in use, the staff connects the connecting tube 231 with the stamping device, so that the stamping device drives the connecting tube 231 to move toward the mounting seat 1, drives the plate 232 to move toward the mounting seat 1, and the extrusion block 233 moves toward the mounting seat 1 accordingly. The second extrusion surface applies a thrust to the first extrusion surface 213, so that the two moving blocks 211 move toward each other, thereby causing the punch 22 to extrude the side wall of the safety needle tube.

[0039] Reference Figure 1 and Figure 2 In order to facilitate the timely resetting of the moving block 211 after the processing is completed, the processing device 2 is also provided with a resetting assembly 24 for resetting the clamping block 21. Two resetting assemblies 24 are relatively arranged, and are respectively located on both sides of the two clamping blocks 21. The resetting assembly 24 includes a fixed block 241, a connecting shaft 242 fixedly connected to one end of the fixed block 241, and a resetting spring 243 sleeved on the connecting shaft 242. The end of the connecting shaft 242 away from the fixed block 241 is fixedly connected to the side wall of the moving block 211. The mounting seat 1 is provided with a sliding groove 244 for the moving block 211 to move. The resetting spring 243 is located between the mounting seat 1 and the fixed block 241.

[0040] After use, the staff separates the connecting tube 231 and the punching device. Under the elastic force of the reset spring 243, the fixed block 241 moves away from the mounting seat 1, so that the connecting shaft 242 drives the moving block 211 to move in the sliding groove 244, thereby returning the moving block 211 to its original position, so that the staff can process the next safety needle tube, thereby improving work efficiency.

[0041] Reference Figure 1 In order to facilitate fixing the position of the safety needle tube during processing, a limiting device 4 is provided on the mounting seat 1, and the limiting device 4 includes a limiting block 41 fixedly connected to the side of the mounting seat 1 away from the bottom plate 31 and a protrusion 42 fixedly connected to the side of the limiting block 41 close to the abutment block 212. The limiting block 41 and the protrusion 42 are integrally formed, and two relatively arranged limiting blocks 41 form a group. The two limiting blocks 41 in the same group are relatively arranged, and the side wall of the protrusion 42 is located in the same plane as the side wall of the limiting block 41, that is, the limiting blocks 41 and the protrusion 42 in the same group jointly form a convex shape, and a placement groove 43 for the safety needle tube to be embedded is jointly formed between the two limiting blocks 41 and the two protrusions 42 in the same group. The placement groove 43 is located on the central axis of the two positioning blocks 234, that is, when the safety needle tube is embedded in the placement groove 43, the distance between the safety needle tube and the two abutment blocks 212 is equal, thereby improving the consistency of the depth of the two grooves during processing.

[0042] In order to increase the stability of the safety needle tube during processing, the two protrusions 42 in the same group are located between the two moving blocks 211 away from the limiting block 41, thereby increasing the range of the bearing force of the safety needle tube during processing.

[0043] In order to further increase the stability of the safety needle tube during processing, two groups of limit blocks 41 are provided. The two groups of limit blocks 41 are arranged opposite to each other, and the two groups of limit blocks 41 are symmetrically arranged along the axis between the two positioning blocks 234, that is, the limit blocks 41 are symmetrically arranged along the central axis of the long side of the mounting seat 1, and at the same time, the two groups of limit blocks 41 are symmetrically arranged along the central axis in the width direction of the mounting seat 1, which increases the limiting effect received by the safety needle tube during processing, thereby improving the stability during processing.

[0044] The implementation principle of Example 1 is as follows: when in use, the staff will embed the safety needle tube into the placement groove 43, and connect the connecting tube 231 with the stamping device, so that under the action of the stamping device, the driving plate 232 drives the extrusion block 233 to move toward the mounting seat 1, and the second extrusion surface abuts against the first extrusion surface 213 so that the moving block 211 drives the abutting block 212 to move toward each other, and the punch 22 performs groove processing on the side wall of the safety needle tube. After the processing is completed, under the action of the reset spring 243, the moving block 211 moves away from each other and returns to the initial position, so that the staff can process the next safety needle tube.

[0045] Example 2

[0046] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the limiting device 4 also includes a fixing component 44 for limiting the position of the safety needle tube in the placement groove 43, and the fixing component 44 includes a mounting block 441 slidably connected to the side of the limiting block 41 away from the mounting seat 1 and a power member for driving the mounting block 441 to move. Two mounting blocks 441 are relatively arranged and are respectively located on two groups of limiting blocks 41.

[0047] Reference Figure 3 and Figure 4 The power part includes a connecting plate 442 fixedly connected to the side of the mounting block 441 close to the mounting seat 1, a driving motor 443 fixedly connected to one side of the mounting seat 1, and a bidirectional lead screw 444 fixedly connected to the output shaft of the driving motor 443. It can be understood that two connecting plates 442 are provided, and the two connecting plates 442 are respectively located at two threads of the bidirectional lead screw 444 with opposite rotation directions. The connecting plate 442 is threadedly connected to the bidirectional lead screw 444. The limit block 41 and the mounting seat 1 are both provided with a moving groove 445 for the connecting plate 442 to move. The bidirectional lead screw 444 is penetrated by the mounting seat 1 and is rotatably connected to the mounting seat 1.

[0048] When in use, the staff starts the drive motor 443, the output shaft of the drive motor 443 rotates, driving the bidirectional screw 444 to rotate, so that the two connecting plates 442 move toward each other, driving the mounting block 441 to move toward the abutment block 212, thereby fixing the safety needle tube embedded in the placement slot 43.

[0049] In order to protect the safety needle tube, a buffer pad 45 is provided on the side of the fixing block 241 close to the abutting block 212 .

[0050] The implementation principle of Example 2 is: when in use, after the staff inserts the safety needle tube to be processed into the placement groove 43, the staff starts the drive motor 443, so that the two mounting blocks 441 fix the safety needle tube, and then operates the drive assembly 23, so that the extrusion block 233 drives the moving block 211 to move toward each other, so that the punch 22 can better process the side wall of the safety needle tube, thereby increasing the stability of the safety needle tube during processing.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
